In the Fig. 1 shown inventive system is used to produce a component B consisting of two parallel, flat wire mesh mats M, M 'of intersecting and welded together at the crossing points longitudinal and transverse wires L, L' and Q, Q ', from the two wire mesh mats M, M 'in a predetermined spaced apart straight ridge wires S, S', which are welded at each end with a wire of the two wire mesh mats M, M ', as well as a between the wire mesh mats M, M' and arranged at a predetermined distance from these , At least partially dimensionally stable insulating body W, for example, an insulating plate I made of plastic.

The system has a base frame 1, on which a horizontal production channel 2, which is indicated only schematically, is preferably arranged centrally. Two upright wire mesh webs G and G 'are drawn off from two supply reels 3, 3' in correspondence with the arrows P1 and P1 ', the mutual distances of the longitudinal wires L, L' and the transverse wires Q, Q 'of each wire mesh web G, G' from one another ie the so-called longitudinal wire and transverse wire divisions, as well as the width of each wire mesh web G, G 'within certain ranges are freely selectable.

Via a wire mesh track guide 4, 4 ', each wire mesh web G, G' passes into a straightening device 5, 5 ', each consisting of a plurality of mutually offset straightening rolls 6, 6', which straighten each wire mesh web G, G '. Each straightening device 5, 5 'has at its inlet side a wire mesh feed device 7, 7', each consisting of a driver roller 8, 8 'and with the driver roller 8, 8' cooperating drive rollers 9, 9 ', wherein each drive roller. 9 '9' brought by pivoting according to the double arrow P2, P2 'either in or out of engagement with the driving roller 8, 8' can be. The wire mesh feeders 7, 7 'have the task of the wire mesh webs G, G' for further processing downstream wire rack slide-in devices 10, 10 'in the direction of the arrows P1, P1' supply, or after completion of production no longer required residual pieces of Wire mesh tracks against the direction of the arrows P1, P1 'from the straightening devices 5, 5' out to promote.

Each wire rack insertion device 10, 10 'is according to the double arrow P3, P3' between a working position in which it is in engagement with the inserted wire mesh web G, G ', and a rest position pivotable in which they disengaged from the wire mesh web G, G 'is. With the help of the grid rail insertion devices 10, 10 ', the structure of which will be described later, the grid paths G, G' are gradually fed wire mesh mats scissors 11, 11 ', each having a respective cutter bar 12, 12' and a cutter bar 13, 13 ' and separating from the endless wire mesh webs G, G 'wire mesh mats M, M' of predetermined length.

The wire mesh mat shears 11, 11 'work in the example shown so that they perform a separating cut and thus of the wire mesh webs G, G' continuously separate successive wire mesh mats M, M '. In the context of the invention, however, it is also possible, the wire mesh mats scissors 11, 11 'in such form and to control that they perform a trimming cut on the longitudinal wires L, L' and in one or two cutting operations from the wire mesh webs G, G 'a selectable section Cut, whose length in the feed direction preferably corresponds to the cross-wire pitch or an integral multiple of the cross-wire pitch.

By slightly curved, the directed wire mesh mats M, M 'only elastically deforming and tangentially opening in opposite longitudinal sides of the production channel 2 Leitvorrichtungen 14, 14', for example, consist of several superimposed curved strips and by means of brackets 15, 15 'and 16, 16 'Are fixed to the base frame 1, the wire mesh mats M, M' so in the production channel 2 that they get there in a parallel position to each other, with a mutual distance which corresponds to the desired thickness of the component B to be produced. In the production channel 2, the two wire mesh mats M, M 'by means of only schematically indicated spacer elements 17, 17', which consist for example of spacer plates and a plurality of vertically spaced superimposed distance guides, safely guided over its entire width and always precisely defined in this Distance kept.

With the aid of a wire mesh mat conveying device 18, which essentially has two pairs of opposing feed elements 19, 19 'and 20, 20' arranged on both sides of the production channel 2, the two wire mesh mats M, M 'are stepped in the guide devices 14, 14 'and conveyed in the production direction P4 along the production channel 2 to the downstream processing stations. The first pair of feed elements 19, 19 'is arranged in the parallel outlet region of the guide devices 14, 14'. The distance between the first feed element pair 19, 19 'of the wire mesh mats scissors 11, 11' and the distance between the two feed element pairs 19, 19 'and 20, 20' from each other must be smaller than the smallest length of the wire mesh mats M, M intended for the manufacture of the component B. 'to ensure safe further promotion of the wire mesh mats M, M' by the wire mesh mat conveyor 18.

From a feeder device 21 individual insulating plates I are fed according to the direction of the arrow P5 a guide device 22 which forms the inlet side of the production channel 2 and is fixed by means of a mounting plate 23 on the base frame 1. The guide device 22 is designed such that the insulating plate I is guided both in the vertical direction and in its position relative to the two wire mesh mats M, M 'and at a predetermined distance from these safely. The length and width of the insulating I is preferably consistent with the length and the width of the wire mesh mats M, M 'match.

In the inlet region of the guide device 22, the insulating plate I is detected by an over the entire length of the production channel 2 extending insulating body conveyor 24 and gradually fed synchronously with the wire mesh mats M, M 'the downstream processing stations of the production plant.

In the present invention, it is possible to supply the feeder device 21 with an insulating material web K instead of the individual pre-lengthened insulating plates I and separate it from the insulating material web K insulator W of a predetermined length by means of an insulating material cutter 25 disposed in the discharge region of the guide device 22. Corresponding embodiments are in the FIGS. 4 to 6 described in more detail.

On both sides of the production channel 2, the guide devices 14, 14 'each have a web wire feeding and cutting device 26, 26' downstream, with which at the same time from both sides of the production channel 2 more wires D, D 'step by step of wire supply coils 27, 27' according to the direction of the arrow P6, P6 'withdrawn, by means of a dressage device 28, 28' straightened, inserted in the horizontal direction in the space between the two wire mesh mats M, M ', through the insulating body W, as from a nail, pushed through and separated from the wire supply , The piercing of the insulating body W is substantially facilitated by heating the tips of the web wires S, S ', wherein the heating takes place for example by an inductively operating heater.

In the context of the invention, it is possible to arrange all web wire feeding and cutting devices 26, 26 'on one side of the production channel 2 in the production direction one behind the other.

In the context of the invention, it is possible to feed already pre-stretched webs S, S 'in vertically extending rows R1 and R2 at selectable angles to the wire mesh mats M, M' the production channel 2 side. Also in this case, the tips of the land wires can be preheated by means of appropriate heaters.

The insulating body W is penetrated by a plurality of rows R1 and R2 of a plurality of, in the vertical direction at a mutual distance one above the other arranged straight web wires S, S '. The webs S, S 'are with their two ends respectively to the corresponding longitudinal wires L, L' of the two wire mesh mats M, M 'and protrude slightly laterally out to secure welding with the corresponding longitudinal wires L, L' of the wire mesh mats M, M 'to ensure. In the illustrated embodiment of the component, the embodiment of the Fig. 10 corresponds to the ridge wires S, S 'within a vertical row R1 and R2 in the same direction horizontally inclined to the wire mesh mats M, M'. In adjacent rows R1; R2 the ridge wires S, S 'are inclined in opposite directions. Seen in the horizontal direction, the webs S, S 'extend in the form of horizontal lines H obliquely between opposite longitudinal wires L and L' of the wire mesh mats M and M '. The respective angles of the webs S, S 'to the longitudinal wires L, L' are selectable, the sense of direction of the webs S, S 'within a row Z changes, so that a truss-like, zigzag-shaped arrangement of the webs S, S' within a row H arises. In the insulating body W, therefore, a plurality of parallel, horizontal lines H of web wires S, S 'are arranged one above the other in the vertical direction, ie the web wires S, S' form in the insulating body W and thus also in the component B to be produced a matrix-like structure with standing upright component B horizontal lines H and vertical rows R1, R2.

The entry angle, under which the webs S, S 'in the space between the two wire mesh mats M, M' are introduced by pivoting the web wire feeding and cutting device 26, 26 'according to the double arrows P7, P7' adjustable. The material and the structure of the insulating body W must be such that the insulating body W fix the web wires S immovable in the subsequent, taking place in the direction of production P4 onward transport in position within the insulating body W. The number, the Einschußwinkel and the mutual vertical distances of the row in a row R1 and R2 in the vertical direction superimposed web wires S and the horizontal distance of the Stegdrahtreihen is selected according to the static requirements of the component B.

In some applications, it may be necessary to make the insulating body W of the component B of such hard materials that it can not be penetrated by the ridge wires S, S 'without deformation of the same. For example, hard plastics, such as polyurethane, lightweight concrete provided with expanded or foamable polystyrene as a lightweight aggregate, gypsum plaster boards or cement-bonded press plates containing waste plastics, wood chips or wood shavings, mineral or vegetable fibrous substances, can be used. In these cases, each web wire feeding and cutting device 26, 26 'is a in Fig. 1 shown schematically piercing device 29, 29 '. Each Vorstechvorrichtung 29, 29 'has a plurality of vertically superimposed tools which serve for molding each of a channel in the insulating body W for receiving a respective stranded wire S, S' and which are arranged on a common, pivotable stand. Here, the stand of the Vorstechvorrichtungen 29, 29 'with the associated Stegdrahtzuführ- and cutting means 26, 26' fixedly coupled, and together with this in the direction of the insulating body W of the component B and away from this movable and together with this according to the double arrow P7 , P7 'swiveling.

In the context of the invention, it is possible, the Vorstechvorrichtungen 29, 29 'according to the im EP-B - 398465 To make the device described. In this case, the advancing movement of the piercing devices 29, 29 'for forming the receiving channel for the web wires S, S' is independent of the feed movement of the Stegdrahtzuführ- and cutting devices 26, 26 '. Only the pivotal movement of each stand of the Vorstechvorrichtungen 29, 29 'for changing the Einschußwinkel the webs S, S' is synchronous with the pivoting movement of each associated Stegdrahtzuführ- and cutting device 26, 26 'according to the double arrows P7, P7'.

The tools for forming the receiving channel for the web wires S, S 'may be formed as solid plug or hollow needles or as a rotating drill, and have a wear-resistant, for example, hardened tip. The plug or hollow needles are preferably preheated in their tips to facilitate penetration of the insulating body W.

The two wire mesh mats M, M 'with the aid of the second feed element pair 20, 20' of the wire mesh mats conveyor 18 stepwise and synchronously with the insulative body W advanced by means of the insulator conveyor 24 together with the web wires S, S 'downstream web welding devices 30, 30th 'in which the webs S, S' in each case at one end by means of welding tongs 31, 31 'with the longitudinal wires L, L' of the wire mesh mats M, M 'are welded. The web wire welding devices 30, 30 'are offset from one another on the outside of the two wire mesh mats M, M'.

The now dimensionally stable component B is progressively conveyed further by a downstream component conveying device 32, which essentially has two pairs of conveying elements 33, 33 'and 34, 34' lying opposite one another on both sides of the production channel 2.

The protruding over the wire mesh mats M, M 'protrusions of the web wires S, S' pose a significant risk of injury in the handling of the component B, hinder the stacking of the components for transport and must therefore be separated so that the ridge wires S, S 'possible flush with the longitudinal wires L, L '. With the aid of the first conveyor element pair 33, 33 ', the component B is fed downstream, on opposite sides of the production channel 2 staggered arranged Besäumvorrichtungen 35, 35', which with the corresponding longitudinal wires L, L 'of the wire mesh mats M, M' laterally projecting web wire ends Cut off the longitudinal wires L, L 'flush.

In the context of the invention, it is possible to divide the finished, trimmed component B by means of horizontally arranged horizontal cutting devices 36, 36 'on both sides of the production channel 2 to the trimming devices 35, 35' in at least two, preferably equally large components. The horizontal cutting devices 36, 36 'are designed such that they can sever both the transverse wires Q, Q' of the wire mesh mats M, M 'and the insulating body W.

In the context of the invention, it is also possible, by means of the feeder device 21, to supply individual, cut-to-length insulating panels I and / or a plurality of vertically extending, endless insulating material webs K in a plurality of webs of the guiding device 22 running one above the other in the vertical direction.

Furthermore, it is possible within the scope of the invention to divide the einstükkigen insulating I and / or the endless Isoliermaterialbahn K in the Isoliermaterialbahn-cutting device 25 by means of an additional cutting tool in at least two, vertically extending over one another or partial webs, so that in the Horizontal cutting devices 36, 36 'only the transverse wires Q, Q' of the wire mesh mats M, M 'are to be cut.

According to the invention, it is also possible in the insulating material web cutting device 25 in horizontally cutting the insulating plate I and the insulating material K not completely cut through, but only from both sides or even from one side of the insulating I and the insulating material K as far as in cut them, that a connecting the two parts web stops in the insulating body W. In the horizontal cutting devices 36, 36 'in this case, only the transverse wires Q, Q' of the wire mesh mats M, M 'severed and made the final division of the finished component B in two or more component parts only at the construction site by breaking the connecting web between the insulators ,

In order to keep the cross wire projections as small as possible when cutting through the component B and to avoid further trimming of the component parts, it is possible within the scope of the invention, as in Fig. 2 illustrated, the distances between the two central longitudinal wires C, C ', between which the component B is cut through, correspondingly smaller than the remaining longitudinal wire pitch of the wire mesh mats M, M' to choose.

The finished, edged component B is conveyed out of the production channel 2 with the aid of the second pair of conveyor elements 34, 34 'of the component conveying device 32, and an in Fig. 4 presented device for removal or even to stack a plurality of components passed.

The distance between the second feed element pair 20, 20 'of the wire mesh mat conveyor 18 and the first conveyor element pair 33, 33' of the component conveyor 32 and the distance between the conveyor element pairs 33, 33 'and 34, 34' must always be smaller than the smallest Length of the wire mesh mats M, M 'used to make the component B, in order to ensure a safe further promotion of the wire mesh mats M, M' between the wire mesh mats conveyor 18 and the component conveyor device 32 and through this.

For the continuous production of the components B, it is absolutely necessary that the two wire mesh webs G, G ', the wire mesh mats M, M' and the insulating material web K or the individual insulating panels I the individual processing stations 11, 11 '; 25; 26, 26 '; 29, 29 '; 30, 30 '; 35, 35 '; 36, 36 'safe and trouble-free supply. To ensure this, the wire mesh slide-in devices 10, 10 ', the feed element pairs 19, 19'; 20, 20 'of the wire mesh mat conveyor 18, the conveyor element pairs 33, 33'; 34, 34 'of the component conveying device 32 and the insulating body conveying device 24 driven by a central main feed drive 37, wherein all elements 19, 19'; 20, 20 '; 33, 33 '; 34, 34 'and the wire mesh slide-in device 10, 10' by means of articulated drive shafts 38, 38 'are interconnected. The feed steps take place cyclically, because the insertion of the web wires S, S ', the welding of the web wires S, S' with the wires of the wire mesh mat M, M 'and the trimming of the web wire end parts respectively at standstill of the wire mesh mats M, M', of the insulating body or of the component B take place. Here, the length of the feed steps corresponding to the cross-wire pitch or an integral multiple of the cross-wire pitch can be selected.

By broadening the production channel 2 and corresponding, individually or jointly carried out lateral adjustment of the feed elements 19, 19 '; 20, 20 ', the conveying elements 33, 33'; 34, 34 'and the elements of the processing stations 25; 26, 26 '; 29, 29 '; 30, 30 '; 35, 35 '; 36, 36 'components B can be made with different predetermined width.

In the Fig. 2 schematically shown insulating body conveyor 24 has a driven by the main feed drive 37 according to the arrow P8 conveyor chain 39, which defines the conveying path of the insulating body W within the production channel 2. The conveyor chain 39 carries a plurality of carrier carrier 40, which are each provided with a driver 41. The drivers 41 are angled, hook-shaped or formed thorn-like, to establish a secure connection with the underside of the insulating body W and thus to avoid any slippage between this and the driver carriers 40 during advancement of the insulating body W.

When supplying the insulating body W in a plurality of superimposed webs, the insulating body conveyor 24 has a further upper conveyor chain 39 'with corresponding Mitnehmerträgern 40' and drivers 41 ', which engage at the top of the insulating body W of the uppermost Isolierkörperbahn.

In the Fig. 2 schematically shown feed elements 19, 20 of the wire mesh mats conveyor 18 have a tilted to the vertical shaft 42, which is driven via a coupling 43 by an angle gear 44 and is mounted in an abutment 45. The angle gear 44 is driven by the main feed drive 37 via the drive shaft 38. Each shaft 42 is provided with a plurality of spaced adjustable spacing transport discs 46 which are rotatable for adjustment on the shaft 42 and are fixedly connected after adjustment by means of a clamping member 47 with the shaft 42.

The transport discs 46 have, as in Fig. 3a shown, multiple, regularly distributed on the circumference lattice engagement recesses 48 with selectable depth, so that flattened teeth 49 arise. The number of Gittereingriffsausnehmungen 48 is selected according to the transverse wire pitch of the wire mesh mats M, M 'such that the transverse wires Q, Q' of the wire mesh mats M, M 'are reliably detected by the transport discs 46 and the slip-free feed of the wire mesh mats M, M' is guaranteed , Due to the inclination of the shafts 42 engage the transport discs 46 of each feed element 19, 19 '; 20, 20 'not only on one, but on a plurality of transverse wires Q, Q' of the wire mesh mats M, M ', so that the tensile force is distributed to a plurality of wires and these are not too heavily loaded during advancement of the wire mesh mats M, M' , The inclination of the shafts 42 also ensures a continuous and slip-free onward transport of the wire mesh mats M, M 'of successive components B, wherein the successive wire mesh mats may have distances in the joint area, for example when trimming the wire mesh mats M, M' or when separating pieces from the wire mesh webs G, G 'arise.

The conveying elements 33, 33 '; 34, 34 'of the component conveying device 32 are analogous to the advancing elements 19, 19'; 20, 20 'of the wire mesh mat conveyor 18 constructed. Only the transport discs 46 have lattice engagement recesses 48 of lesser depth. The wireframe slide-in devices 10, 10 'have substantially the same elements as those in FIG Fig. 2 shown advancing elements 19, 20 of the wire mesh mat conveyor 18. The only difference is that, as in Fig. 3b illustrated, the lattice engagement recesses 48 of the transport discs 50 are substantially deeper so that they have pointed teeth 51. This shaping of the teeth 51 ensures that the teeth 51 reaching from the side into the non-guided wire mesh web G, G 'reliably detect the transverse wires Q of the wire mesh webs G, G' and advance the wire mesh webs G, G 'without slip.

It is possible to produce with the system according to the invention components B, in which the wire mesh mats M, M 'different structure, ie, different longitudinal wire pitches and / or transverse wire pitches and different diameters of the longitudinal wires and / or transverse wires. However, the various transverse wire pitches must be integer multiples and may be 50, 100 or 150 mm, for example. Another limitation is that it must be ensured that the webs S, S 'can be positioned so that, despite these different wire divisions and wire diameter can be securely welded to the longitudinal wires of the two wire mesh mats M, M'.

It is possible to produce components B using the system according to the invention, in which one and / or both wire mesh mats M, M 'project beyond the insulating body W on one or both sides running parallel to the production direction P4. To achieve this, either the driver 41 are raised or extended, or the conveyor track of the conveyor chain 39 is raised so that the lower, parallel to the production direction P4 extending side surface of the insulating body W is raised accordingly, whereby one and / or both wire mesh M, M 'form the desired supernatant on this side. The conveyor track of the arranged at the top of the insulating body W upper conveyor chain 39 'must be lowered accordingly or the driver 41' lowered or extended accordingly.

For the manufacture of components B, in which the insulating body W project beyond the two wire mesh mats M, M 'on one or both side or sides running parallel to the production direction P4, the conveying path of the lower conveyor chain 39 is lowered and, if appropriate, the conveying path of the upper conveyor chain 39 'raised so that the lower and possibly the upper, parallel to the direction of production P4 extending side surface of the insulating body W is lowered or raised accordingly, whereby the insulating body W, the two wire mesh mats M, M' on one or both sides with the desired supernatants surmounted.

The continuous production of the components B by means of the installation according to the invention preferably takes place in such a way that the wire mesh mats M, M 'of successive components B are separated from each other only by a negligibly narrow parting line between the longitudinal wires of successive wire mesh mats M, M' and also the corresponding insulator W associated therewith successive components B follow each other without appreciable gaps.

In the context of the invention, however, it is also possible to produce components B in which one and / or both wire mesh mats M, M 'project beyond the insulating body W at one or both, perpendicular to the direction of production P4 side. If one or both wire mesh mats M, M 'should project beyond the insulating body W on both sides, the insulating bodies W of adjacent components B are fed by the feeder device 21 with appropriately selected distances to the production channel 2 and fed there at these mutual distances. When using an endless insulation material web K, a part corresponding to this distance must be separated from the web K during separation of the insulating body W. The two joints between the wire mesh mats M, M 'successive components B are either exactly opposite or laterally offset from each other.

For the manufacture of components B, in which the insulating body W project beyond the two wire mesh mats M, M 'on one or both sides perpendicular to the production direction P4, the wire mesh mats M, M' are advanced in the production channel 2 at a predetermined distance.

Each wire mesh mat M or M 'consists of several longitudinal wires L and L' and of a plurality of transverse wires Q and Q ', which intersect each other and at the crossing points welded together. The mutual distance of the longitudinal wires L, L 'and the transverse wires Q, Q' to each other is selected according to the static requirements of the device. The distances are preferably the same size, for example, selected in the range 50 to 150 mm, so that the respective adjacent longitudinal and transverse wires form square mesh. In the context of the invention, the meshes of the wire mesh mats M, M 'can also be rectangular and, for example, have short side lengths of 50 mm and long side lengths in the range of 75 to 100 mm.

In the insulating body W a plurality of through holes 92; 93, 93 ', which run perpendicularly and / or at a selectable angle in each case obliquely to the cover surfaces 91, 91' of the insulating body W. The through holes 92; 93, 93 'are drilled in the insulating body W or punched out of this. In the context of the invention, it is also possible, in the production of the insulating body W by appropriate shaping of the molds, the through holes 92; 93, 93 'already auszusparen. The directions of the oblique through-holes 93, 93 'are selected such that, when the device is used as a vertical wall, at least the through-holes 93, 93' of a type run obliquely from top to bottom, the directions being parallel to the longitudinal wires L, L 'and / or parallel to the transverse wires Q, Q' of the wire mesh mats M, M 'extend. The number, dimensions and distribution of all through holes 92; 93, 93 'is freely selectable.

The shape of the through holes 92; 93, 93 'is also arbitrary and may be, for example, square, rectangular or round. For round cross-section of the through holes 92; 93, 93 ', the diameters are preferably in the range of 50 to 100 mm. The distribution of the through holes 92; 93, 93 'in the component can be regular or random in the context of the invention, wherein to avoid resonance effects a random and asymmetrical distribution of the through holes 92; 93, 93 'is advantageous.

As from the in Fig. 9 shown in the wire mesh mat M at the edge of the component B, the longitudinal wires L and the longitudinal edge wires L1 each flush with the edge cross wires Q1 and the transverse wires Q and the edge cross wires Q1 each flush with the edge wires L1 from. The same applies analogously to the wires L ', L1'; Q ', Q1' of the other wire mesh mat M '.

In Fig. 10 is a side view of the component B seen in the direction of the cross-wire crowd shown. The ridge wires S, S 'are each welded to the longitudinal wires L and L' of the wire mesh mat M and M '. In this case, the web wires S running parallel in the cross-wire direction form a row R1 extending perpendicular to the plane of the drawing, and the corresponding web wires S 'form another row R2 extending perpendicular to the plane of the drawing and running obliquely in the opposite direction to the row R1. The in-plane webs S, S 'of different rows R1, form a Stegdrahtreihe H, which in Fig. 10 runs parallel to the drawing plane. In the production of the component B in the systems according to the invention, the rows R1, R2 extend in the vertical direction perpendicular to the production direction P4, while the web wire rows H extend in the horizontal direction parallel to the production direction P4.

The FIGS. 11 and 12 each show embodiments with different angles between the ridge wires S, S 'and the corresponding longitudinal wires L, L' of the wire mesh mats M, M ', wherein according to Fig. 11 Within a component, different angles within a row of ridge wires are possible.

Fig. 13 shows a component B, in which in a row R1, the web wires S in the same direction obliquely between the longitudinal wires L and L 'of the wire mesh mats M, M', while in the next row R2, the dashed lines drawn bar wires S 'also in the same direction obliquely, but with opposite Direction sense between the corresponding longitudinal wires L, L 'run, that is, the device has several rows of the same direction oblique ridge wires with changing sense of direction from row to row. In the context of the invention, the rows of corrugated webs oriented in the same direction can also run between the transverse wires Q, Q 'of the wire mesh mats M, M'.

Fig. 14 shows a component B with oppositely inclined ridge wires S, S 'each row R1, R2, wherein the spacings of adjacent ridge wires in the row are chosen such that the mutually facing ends of the ridge wires come as close as possible, thereby optionally two ridge wires together in one Operation with the corresponding grid wire can be welded.

As Fig. 15 shows, the insulating body W can also be arranged asymmetrically to the two wire mesh mats M, M '. Here, the diameters of the wires L ', L1'; Q ', Q1, the wire mesh mat M' located farther to the insulating body W advantageously larger than the diameters of the wires L, L1; Q, Q1 of the insulating body W closer wire mesh mat M.

For stiffening the grid body at its edges can according to Fig. 16 additional, preferably perpendicular to the wire mesh mats M, M 'extending and with the corresponding edge wires L1, L1'; Q1, Q1 'of the wire mesh mats M, M' welded Edge webs S1 are provided. The diameter of the edge webs S1 is preferably equal to the diameter of the webs S, S '.

In Fig. 17 is a component B shown according to the invention, the insulating body W at the parallel to the transverse wires Q, Q 'extending side surfaces 94 not with the two wire mesh mats M, M' concludes, but is surmounted by these laterally. By this embodiment, when linking two similar components is achieved that the insulating body of adjacent components can be arranged without a gap, while the wire mesh mats of the two components each overlap each other and thereby form a bearing overlap shock. Similarly, the wire mesh mats M, M 'laterally project beyond the parallel to the longitudinal wires L, L' extending side surfaces 94 '.

The insulating body W can in the context of the invention on all side surfaces 94, 94 'flush with the inner wire mesh mat M' and only overtop the outer wire mesh mat M in practical use. Analogously, it is possible within the scope of the invention for the insulating body W to terminate flush with the outer wire mesh mat M on all side surfaces 94, 94 'and to project beyond only the inner wire mesh mat M' which is used in practice.

One or both of the wire mesh mats M, M 'may laterally project beyond the insulating body W on all side surfaces 94, 94' thereof. In all embodiments, any Randstegdrähte S1 can be arranged so that they extend outside of the insulating body W or flush with these laterally connect.

The longitudinal and transverse wires L, L ', L1, L1'; Q, Q ', Q1, Q1' of the wire mesh mats M, M 'and the web wires S, S', S1 may have any cross section. The cross sections can be oval, rectangular, polygonal or square.

Fig. 18 shows a component B, which has a two-part insulating body W '. In doing so, if necessary, the parts of the insulating body W 'are glued together at their contact surfaces. The two parts of the insulating body W 'include cavities 95 for the purpose of saving material, which, however, can also be filled with other materials, for example pourable, free-flowing and flowable insulating materials, such as wood and foam chips, sand, plastic, rice or straw waste , The insulating body W 'may also consist of several interconnectable parts, for example, have a multi-layered structure. It is also possible to provide a one-piece insulating body W with cavities 95.

Like in the Fig. 19 is shown schematically, an outer shell 96 is applied, for example, made of concrete to the insulating the outer body W, W ', enclosing the outer wire mesh mat M and together with this the load-bearing component of the finished concrete component B. 'forms. The thickness of the outer shell 96 is selected according to the static and the sound and thermal requirements of the component B 'and is for example 20 to 200 mm. If the component B 'used as a ceiling element, it must be 50 mm for static reasons, the minimum thickness of the outer shell 96.

On the inner wire grid mat M 'intended for forming the component inner side, an inner shell 97 is applied, which adjoins the insulating body W, W', encloses the inner wire mesh mat M 'and consists for example of concrete or mortar. The thickness of the inner shell 97 is selected according to the static as well as the sound and thermal requirements of the component B 'and is for example 20 to 200 mm. The two shells 96, 97 are preferably applied at the point of use of the component B ', for example sprayed on by a wet or dry process. The statically required thickness of the outer shell 96 and the inner shell 97 determined also the distance of the insulating body W, W 'of the wire mesh mats M, M'.

Since lying in the interior of the component B 'portions of the web wires S, S' and possibly also the edge webs S1 are not covered with concrete and therefore exposed to corrosion, the web wires S, S 'and S1 must be provided with a corrosion protection layer. This is preferably achieved by galvanizing and / or plastic coating of the webs S, S ', S1. However, in order to allow the webs S, S ', S1 to be welded to the wires of the wire mesh mats M, M', the plastic layer must not cover the end regions of the webs S, S 'or edge webs S1. For reasons of cost, it has proved to be advantageous to use galvanized wire already during the production of the grid body A, at least for the bar wires S, S ', S1. The webs S, S ', S1 can also be made of stainless steel grades or other non-corrosive materials, such as aluminum alloys, which must be connected to the wires of the wire mesh mats M, M', preferably welded. In the context of the invention, the wires L, L ', L1, L1'; Q, Q ', Q1, Q1' of all wire mesh mats M, M 'or at least the wires L, L1; Q, Q1 of the outer wire mesh mat M be provided with a corrosion protection layer or consist of stainless steel grades or other, non-corrosive materials. The corrosion protection layer or the materials must be such that a welding of the wires of the wire mesh mats M, M 'with the web wires S, S' and with the edge web wires S1 is easily possible. The corrosion protection layer can consist for example of a copper or zinc layer. In the context of the invention, it is possible, in the finished device B 'before the application of the outer and inner shell, at least the outer wire mesh mat M together with the protruding from the insulating body W, W' areas of the land wires S, S 'and the edge web wires S1 to provide a corrosion protection layer. This can be, for example by dipping the corresponding wire mesh mat M together with adjacent areas of the webs S, S 'and the edge web wires S1 done in a painting or galvanizing.

For static reasons and / or to increase the sound insulation, it may be necessary to provide the component B 'on at least one component side with a very thick concrete shell with a two-ply reinforcement. In Fig. 20 is a section of a component B 'shown with a very thick outer shell 96' made of concrete, the outer shell 96 'is reinforced with an outer, additional reinforcement mat 98 whose distance to the outer wire mesh mat M according to the static requirements for the component B' freely selectable is. The outer additional reinforcement mat 98 prevents cracks forming in the outer shell 96 'due to temperature and shrinkage stresses.

For structural reasons and / or to increase the sound insulation, the component B 'can also be provided with a very thick inner shell 97', which is either provided only with an inner wire mesh mat M 'or, like Fig. 21 shows reinforced with an inner wire mesh mat M 'and an inner, additional reinforcement mat 98'. The distance of the inner additional reinforcement mat 98 'to the inner wire mesh mat M' is freely selectable according to the static requirements for the component B '. The diameters of the wires of the outer additional reinforcement mat 98 and / or the inner additional reinforcement mat 98 'are preferably larger than the diameters of the wires of the two wire mesh mats M, M' and are for example in the range of 3 to 7 mm. If the thick inner shell 97 'is reinforced only with the inner wire mesh mat M', the diameters of the wires L ', L1'; Q ', Q1' of the inner wire mesh mat M 'and the land wires S, S', S1 are preferably larger than the diameters of the grid wires L, L1; Q, Q1 of the outer wire mesh mat M and are in the range of 5 to 6 mm, for example. This applies analogously to the case that the thick outer shell 96 'is reinforced only with the outer wire mesh mat M.

The inner wire mesh mat M 'and the inner additional reinforcement mat 98' may be connected by a plurality of spacer wires 99, which are preferably perpendicular to the inner wire mesh mat M 'and inner additional reinforcement mat 98' and whose mutual, lateral spacing is freely selectable. The diameter of the spacer wires 99 is preferably equal to the diameters of the wires of the wire mesh mats M, M '.

In the context of the invention, the outer additional reinforcement mat 98 and the outer wire mesh mat M can also be connected to spacer wires, which extend preferably perpendicular to the outer wire mesh mat M and outer additional reinforcement mat 98. These spacer wires are arranged with selectable lateral distances from each other and have diameters which are preferably equal to the diameters of the wires of the two wire mesh mats M, M '.

The thick, provided with two-ply reinforcement concrete shells 96 'and 97' can also be cast in situ concrete at the point of use of the component B ', wherein the outer boundary of the concrete shells 96', 97 'is formed by a shuttering, not shown.

In order to improve the adhesion on the two, the wire mesh mats M, M 'facing top surfaces 91, 91' of the insulating body W, W 'when peaking the outer shell 96 and the inner shell 97 of the insulating and prevent unwanted downflow of the material during application, the cover surfaces 91, 91 'of the insulating body W, W' can be roughened. As in Fig. 22 is shown, the top surfaces 91, 91 'can be provided with recesses 100, for example, by means of gears or rollers that carry on their circumference spines or nubs, during the manufacture of the component B in the Dekkenflächen 91, 91' of the insulating body W. , W 'are shaped.

In the context of the invention, it is according to Fig. 23 possible to provide the insulating body W, W 'at its top surfaces 91, 91' with transverse grooves 101 which extend in the horizontal direction when using the device as a wall element. The wells 100 and the transverse grooves 101 can be generated in the invention in the production of the insulating body.

To improve the adhesion of the outer concrete shell 96 on the insulating body W, W ', as in Fig. 24 shown, a plaster base grid 102 find use, which rests on the top surface 91, 91 'of the insulating body W, W' and by the web wires S, S ', S1 or the insulating body W, W' is fixed. The plaster base grid 102 consists for example of a fine mesh welded or woven wire mesh with a mesh size of for example 10 to 25 mm and wire diameters in the range of 0.8 to 1 mm. The plaster base grid 102 can also be made of expanded metal in the context of the invention. Between the plaster base 102 and the top surface 91, 91 'of the insulating body W, W' an additional separation layer 103 may be arranged, for example, aluminum foil, impregnated construction paper or cardboard, which also serves as a vapor barrier and is preferably connected to the plaster base grid 102.

It is understood that the described embodiments may be varied variously within the scope of the general inventive concept; In particular, it is possible to attach the outer shell 96 and / or the inner shell 97 already in the factory on the component.

Insulating body W, W 'as well as separating layer 103 may be made of hard or non-flammable materials or may be impregnated or provided with substances which make insulating body W, W' and separating layer 103 difficult or non-flammable. The insulating body W, W 'and the separating layer 103 may also be provided with a difficult or non-flammable paint.

In the context of the invention, it is possible to produce a prefabricated wall made of cast concrete from several components. This manufacturing method is characterized by the fact that several central components B each with their narrow sides next to each other adjoining be arranged with a selectable distance between two formwork walls and the spaces between the insulating bodies W, W 'of the components B and the shuttering walls are completely filled with concrete. Here, the concrete shells are poured in several operations, but between the individual operations, the concrete may not cure completely.

The method is used to produce vertical prefabricated walls. In this case, a plurality of components B are arranged abutting each other in the vertical and horizontal direction adjacent to each other for forming a vertical prefabricated part wall and the lower components B are each anchored in a stationary base plate, adjacent in a horizontal direction adjacent components B in a straight line and / or along a curved line and / or are arranged at any angle to each other.
