Description

The present invention relates to a receiving device of a mounting support system according to the preamble of claim 1.

A mounting support system of this type is generally used for installing or connecting, for example, prefabricated concrete balcony support panels to the ceilings and/or walls of a building.

The assembly support system consists of two external, individual units, namely a connection element and a receiving device, each of which is designed with a coupling or a matching coupling counterpart. When producing the concrete support slab, referred to below as the prefabricated component, a number of evenly spaced connection elements are cast into it ready for assembly, while the receiving devices are installed on site, i.e. on the construction site when a part of the building, for example a concrete ceiling, is completed. In other words, when producing a building ceiling, for example, the receiving devices are cast into the ceiling either on the construction site or, in the case of a prefabricated concrete ceiling, in the factory and firmly anchored in the concrete ceiling using appropriate reinforcing bars.

To mount the prefabricated component on the building part, only the coupling pieces of the connection elements on the prefabricated component side must be connected to the coupling counterparts of the receiving devices on the building part side. In order to align the surface of the prefabricated component with the surface of the building ceiling, an adjustment process is also required, i.e. raising or lowering the concrete support plate in certain areas if necessary. For this purpose, the connection elements spaced along the connection edge of the prefabricated component or the opposite

Support devices allow vertical movement of the prefabricated component when it is already connected, i.e. when it is already loaded. This adjustment process also serves to compensate for manufacturing tolerances when manufacturing the prefabricated component and/or the building part. For example, the horizontal distances between the individual connection elements must essentially match those of the support devices. However, this is not always the case. In the case of larger deviations, tolerance compensation in the horizontal direction must therefore be made possible in order to enable coupling of the connection elements and/or support devices that lie outside the installation tolerances.

Despite this adjustment possibility, however, the connecting element and the receiving device must be able to be installed in a simple and safe manner and the connecting element must be able to be coupled to the receiving device without major difficulty.

It is therefore an object of the invention to provide an assembly support system with a building-side receiving device and a prefabricated component-side connecting element, which allows an adjustment of the prefabricated component to compensate for manufacturing tolerances and at the same time can be mounted and coupled safely and easily.

This object is achieved by a mounting support system having the features of claim 1.

The invention therefore consists in the assembly support system comprising, among other things, a tie rod to which a connection element on the part of the production component can be coupled and which can be brought into engagement with an abutment held in the building part via an anchor stop and an interposed, movably mounted pressure disk, a device for ensuring a predetermined relative position of two of the above-mentioned assembly elements. This device allows the two assembly elements to

· ·

Hold in position at the beginning of the coupling process so that alignment of the elements for coupling the tension anchor with the connecting element is considerably simplified.

According to claim 2, the device is a deformable holding element that holds the pressure disk in a predetermined design position on the tie rod. The holding element can be elastically or plastically deformable so that the pressure disk can be moved to compensate for manufacturing tolerances on the tie rod by applying the deformation work, while ensuring optimal force introduction into the abutment.

A further development of the subject matter of the invention according to claim 13 provides that the connecting element for coupling with the tie rod has a coupling piece in the form of a screw thread, which is formed on a tensile component of the connecting element, for example a tie rod, and is in operative engagement with a coupling counterpart in the form of a sleeve, which is arranged on the tie rod, wherein the device for ensuring a predetermined relative position is a visual unscrewing control device, which indicates the minimum screw-in depth of the screw thread in the sleeve for a still sufficient force transmission.

Further advantageous embodiments of the invention are the subject of the remaining subclaims.

The invention is explained in more detail below using preferred embodiments with reference to the accompanying drawings.

Fig. 1 shows the overall side view of a mounting support system with a connection element anchored in a prefabricated component and a building-side receiving device according to a first preferred embodiment of the invention,

Fig. 2 is an enlarged partial side view of a receiving device according to a second preferred embodiment of the invention,

Fig. 3 is an enlarged partial side view of a receiving device according to a third preferred embodiment of the invention,

Fig. 4 is an enlarged partial side view of a receiving device according to a fourth preferred embodiment of the invention and

Fig. 5 is an enlarged partial side view of a receiving device according to a fifth preferred embodiment of the invention.

According to Fig. 1, the assembly support system according to a first preferred embodiment of the invention comprises a connection element 1 on the prefabricated component side and a receiving device 2 on the building part side, which is designed as a unit external to the connection element 1.

The connecting element 1 essentially consists of an upper component 3 capable of withstanding tensile loads, a lower component 4 capable of withstanding compression loads and a strut 5 capable of absorbing a transverse force, all of which are cast with their one end sections for firm anchoring in a prefabricated component 6. The upper component 3 capable of withstanding tensile loads is formed with a coupling piece 7 at its other end section protruding from the prefabricated component.

The receiving device 2, which can be firmly anchored in a building part 9, consists of a pressure element 11 and a tension element 10 for introducing a pressure or tension force into the building part 9, as well as a coupling piece 7 of the connecting element 1, which is designed to fit the tension element 10.

arranged coupling counterpart 12, which can be brought into engagement with the coupling piece 7 of the connecting element 1 in the anchored state of the receiving device 2.

As can be seen from the side view according to Fig. 1, the tensile, upper component 3 of the connection element is formed from a central tension rod 3a, preferably made of a steel material, e.g. a stainless steel, to one end of which two iron rods aligned parallel to one another and/or an iron grid 13 (preferably made of structural steel) are welded or screwed. The iron rods and/or grids 13 serve as reinforcement for firmly anchoring the upper component in the prefabricated component (e.g. a concrete support slab) during its manufacture. At the opposite end of the central tension rod 3a, it is provided with an external screw thread of a predetermined length, which represents the above-mentioned coupling piece 7.

The pressure-loadable, lower component 4 of the connecting element comprises a pressure rod 4a, which is aligned essentially parallel to the central pull rod 3a at a predetermined height distance from it. An end section of the pressure rod 4a is bent or curved upwards in the direction of the central pull rod 3a, with a pressure plate 14 being welded to the end of this bent end section, which extends at right angles to the bent end section of the pressure rod 4a. This bent end section is also completely cast into the finished component.

The opposite end section of the pressure rod 4a is provided with an external screw thread 8 of a predetermined length, onto which an adjusting nut or sleeve 15 is screwed for adjusting the length of the pressure rod 4a. A sleeve 15a extending to the finished component 6 is attached to the sleeve 15 (preferably by welding, gluing or plugging), which surrounds the rear area of the external thread 8 and thus protects the thread 8 from contamination and damage.

protects. In addition, the sleeve 15a has a predetermined axial length with respect to the length of the thread 8 and the sleeve 15 in order to serve as a type of unscrewing control. This means that the axial length of the sleeve 15a is set in such a way that the sleeve 15 can be unscrewed from the thread 8 until the rear end section of the thread 8 becomes visible. In this axial position, there are still enough threads active that a sufficient pressure force can be transmitted. The sleeve 15a therefore defines the adjustment window of the sleeve 15 or the lower component 4.

Two transverse force rods 5a (only one transverse force rod can be shown in the side view according to Fig. 1) run between the central tension rod 3a and the pressure rod 4a of the connecting element 1, which form the strut 5 that absorbs the transverse force. In the side view according to Fig. 1, the transverse force rods 5a have a substantially S-shaped contour and are welded in their longitudinal extension on the one hand in the area of the external thread 7 to the central tension rod 3a via two axially spaced welding points and on the other hand in the area of the bent end section to the pressure rod 4a via two axially spaced welding points. In the area in which the transverse force rods 5a bridge the height difference between the upper tension rod 3a and the lower pressure rod 4a, a plastic sleeve 16, shown only in outline in Fig. 1, is inserted, which fits snugly against the transverse force rods 5a and the tension and pressure rods 3a, 4a and thus additionally reinforces the internal statics of the connecting element 1 and also forms contact surfaces for fastening thermal insulation panels (not shown).

Furthermore, the connecting element 1 according to the first preferred embodiment of the invention has a support device 17 for introducing vertical forces into the building, i.e. into a building wall 25, and if necessary also for adjusting the height of the prefabricated component 6 to be assembled with respect to

&bull;&bull;J

of the building part 9. This support device 17 consists of a base 18 to which a support profile (in this case a W-beam or also a T-, &EEgr;-beam, etc.) 19 is welded edgewise. A through hole 20 is formed in the support profile 19, the dimensions of which allow the pressure rod 4a to be passed through. For stability reasons, the pressure rod 4a passed through the through hole 20 is welded to the support profile 19. On the upper edge section of the support profile opposite the base 18, the central tension rod 3a rests in the area behind the external screw thread 7, preferably between the two axially spaced welding points of each transverse force rod 5a and is additionally welded to the upper edge section and thus secured against slipping. As can be seen from this design description, the support device 17 is not suitable per se for height adjustment. In order to make this possible, however, washers of different thicknesses can be pushed under the base 18 in order to raise or lower the prefabricated component 6.

The tension element 10 of the receiving device 2 according to the first embodiment of the invention consists, as can be seen from Fig. 1, of two rectangular metal plates 42 arranged upright and at a parallel distance from one another (only one metal plate can be shown in the side view of Fig. 1), which are connected to one another at a lower edge section by a web plate 43 welded to it. A tension rod 29 made of structural steel is welded to the outer sides of each of the two metal plates 42. A force transmission plate or a pressure disk 31 rests on the rear edges of the metal plates 42, in which at least one transverse (horizontal) elongated hole is formed. Alternatively, a crossing horizontal and vertical elongated hole or simply a through hole of a predetermined diameter can be formed. A tension rod 33 is passed through the through hole from the front edges of the metal plates 42 in

Form of a metal extruded profile, to the rear end section of which a stop or anchor plate 34 is welded. The diameter of the through hole in the pressure disk 31 is, as can be clearly seen in Fig. 1, significantly larger than the diameter of the tension rod 33, so that the latter can move vertically and/or horizontally within the through hole.

In order to prevent the thrust washer 31 from slipping due to its oversized through hole and thus its incorrect or asymmetrical installation before and during installation of the tie rod 33, i.e. before a tensile load is applied to the tie rod 33, an elastic bracket or U-shaped spring element 35 is attached to the latter, which rests on the end of the tie rod 33 or on the anchor disk 34 welded to it and holds the thrust washer 31 in the correct longitudinal position essentially centrally to the tie rod 33. This means that the spring element 35 reliably prevents the thrust washer 31 from moving along the tie rod 33, so that when it is inserted into the receiving device, the thrust washer 31 comes to rest behind the metal plates 42 almost automatically without jamming or tilting. The spring element 35 preferably consists of a steel or plastic material and is fixed to the pressure disk 31 by welding, soldering, gluing or a positive or non-positive connection.

According to Fig. 1, the web plate 43 is bent downwards at a right angle in a central section and is welded to the pressure element 11 at its lower edge to form a unit. The web plate 43 forms a type of edge and end face protection for the building part 9, in this case a precast concrete ceiling, which absorbs an impact of the protruding connection elements 1 on the precast concrete ceiling, particularly during assembly of the precast component 6, i.e. the coupling of the connection elements 1 to the receiving devices 2, and thus prevents the ceiling edges from buckling.

A screw sleeve or sleeve 12 is welded to the front end of the tie rod 33. A sleeve 21 is attached to the end face facing away from the tie rod 33, which also serves to protect the external thread 7 of the central tie rod 3a of the connecting element 1 from contamination and damage and also takes on the function of an unscrewing control corresponding to the sleeve 15a.

The pressure element 11 of the receiving device 2 consists of two parallel extending pressure rods 22 (only one pressure rod can be shown in the side view), to one end of which a pressure plate 23 is welded perpendicularly to these and which are preferably welded at their other end sections to an iron grid which firmly anchors the pressure element 11 in the building part 9. At this point it should be noted that, as can be seen from Fig. 1, the pressure rods 22 are arranged in a lower third of the concrete ceiling. In this respect, the term "compression rod" refers only to their function in the assembly support system according to the invention. In addition, however, they also serve as tensioning elements within the concrete ceiling to absorb bending moments resulting from the dead weight of the ceiling and loads placed on it, for example according to the principle of prestressed concrete technology. In order to position the compression element 11 in the correct position for these functions during the manufacture of the building part, i.e. the concrete ceiling 9, spacers 24 are welded to the compression plate between the two compression rods 11 and to the rear ends of the compression rods, on which the compression elements 11 and thus also the tension elements 10 are supported on the substrate via the web plate 43. Since these spacers 24 may be visible on the underside of the concrete ceiling 9 after its completion and are therefore exposed to corrosion, they can optionally be partially covered with a protective layer, e.g. made of plastic.

For the assembly of the prefabricated component 6, for example in the form of a concrete support slab as a balcony platform to the building part 9,

For example, if a concrete ceiling is installed using the mounting support system described above, the following is carried out:

Prerequisites for assembly are, of course, the correct prefabrication of the prefabricated component 6 with a certain number of essentially evenly spaced connection elements 1 on the assembly edge of the prefabricated component 6 and the preparation of the building part 9 by anchoring the same number of receiving devices 2 with equal spacing in the building part 9. This means that the reinforcing iron 29 with the metal plates 42 and web plate 43 welded to it and the spacers 24 with pressure element 11 are concreted into the building part, in this case the concrete ceiling 9, in such a way that a chamber space 26 freely accessible from the top of the concrete ceiling 9 remains behind the metal plates 42.

The concrete components prepared in this way are now assembled on site, i.e. on the construction site, by first screwing the tie rods 33 onto the central tie rods 5a of the connecting elements 1. This process can of course also be carried out in the production plant for the prefabricated component 6. The prefabricated component 6 is then moved closer to the connecting edge of the building part 9, for example by means of a crane, until the anchor plates 34 together with the pressure disks 31 held to them by means of the spring elements 35 reach behind the metal plates 42. During this assembly step, due to the arrangement of the spring elements 35, it is not necessary to pay attention to the correct position of the pressure disks 31 in relation to the anchor plates 34, since the spring elements 35 hold the pressure disks 31 elastically in position. This means that the spring elements 35 prevent the pressure disks 31 from moving away from the anchor plates 34 and thus blocking the insertion of the tie rod 33 between the metal plates 42. The assembly can therefore be carried out much more safely and easily at this point. In addition, the pressure discs 31 allow for compensation of manufacturing tolerances by being

t

formed elongated holes can be moved against the slight preload force of the spring elements 35 in order to be positioned exactly behind the metal plates 42.

If the prefabricated component 6 is now slowly lowered, the support devices 17 come into contact with the building 25, while the pressure rods 8 are supported against the pressure elements 11 via the sleeves 15. Since the assembly support system described is made entirely of steel elements, deformations in the elastic and partially elastic range are inevitable under such high loads, so that readjustment is required for an exact alignment of the prefabricated component 6 with respect to the building part 9.

This readjustment is primarily carried out via the sleeves 15 and , which can be screwed back and forth along the external threads 7 and 8 and thus change the angle of inclination of the prefabricated component 6 with respect to the building 25. The adjustment path of the sleeves 12 and 15 can be controlled using the sleeves 15a and 21 attached to them, which cover the rearmost section of the external threads 7 and 8. Preferably, the external threads 7 and 8 themselves serve as end markings for the maximum possible unscrewing path of the sleeves 12 and 15. As soon as the sleeves 15a and 21 release the external threads 7 and 8, the maximum unscrewing position of the sleeves 12 and 15 is reached, in which a sufficient coupling between the respective connection element and the receiving device is still guaranteed.

In addition to the adjustment process described above, it is also possible to slide washers or plates (not further shown in Fig. 1) under the bases 18 of the support devices in order to partially raise the prefabricated component 6 or to compensate for unevenness in the support surface of the building 25.

Fig. 2 shows a second embodiment of the invention, which is directed to a construction of the receiving device 2 which is modified from the first embodiment, in particular the mounting of the pressure disk 31 on the tie rod 33. In this respect, only the features which are different from the first embodiment are described below, while with regard to the remaining construction of the assembly support system according to the second embodiment, reference is made to the above description.

As can be seen from Fig. 2, the pressure disk 31, which can be moved on the tie rod 33, is filled with foam using a material which allows the movements of the pressure disk 31 on the tie rod 33 required for tolerance compensation, but still holds it in the design position, preferably in contact with the anchor plate 34. This material 27 can be, for example, a PU foam or a Styrofoam, which bonds to the surface of the tie rod 33 and the inner surface of the elongated hole within the pressure disk 31. In contrast to the first embodiment, however, when the pressure disk 31 is moved to compensate for manufacturing tolerances, the foaming material 27 is not elastically deformed but essentially plastically. This means that after the respective pressure disk 31 has been correctly adjusted, it is held in this new position by the plastically deformed foam 27. This has the advantage that if the tie rod 33 has to be removed from the metal plates 42 again for any reason during the assembly process, the pressure disk 31 will rest on the metal plates 42 in the correct position after the tie rod 33 has been reinserted between them and thus does not need to be adjusted again.

Furthermore, in the second embodiment, the arrangement of a sleeve on the sleeves 12 and 15, as provided in the first embodiment, was dispensed with. Instead, markings are provided on the respective external threads 7 and 8 of the central pull rod 3a and the push rod 4a of the connecting element 1.

7a and 8a are attached, which indicate the end of the permissible unscrewing path of the sleeves 12 and 15. A paint application, an inserted O-ring or a molded part may serve as a marking.

In the second embodiment, the rear ends of the external threads 7 and 8 remain essentially unprotected. However, the formation of a sleeve with a predetermined length and the fastening of the sleeve to the screw nuts or sleeves are not necessary, which makes the construction overall simpler and therefore more cost-effective.

Fig. 3 shows a third embodiment of the invention.

According to Fig. 3, the pressure disk 31 is held in position by means of a spring-elastic spacer 35'. The spacer 35' consists in this case of a spring steel sheet which has a through hole in a central section through which the tension rod 33 passes. On both sides of the through hole, the spring steel sheet is bent into two legs which extend away from one another in a substantially V-shape, the free ends of which rest on the pressure disk. For this purpose, the free ends of the legs are bent upwards at their corner edge areas at a substantially right angle, thereby forming a type of locking projection or simply contact surface which is pressed against one end face of the pressure disk 31 in a spring-elastic manner. Between the upwardly bent corner edge areas, there remain longitudinally extending tabs which extend into the through hole of the pressure disk 31 and rest against its inner wall. The ring area of the spring steel sheet surrounding the through hole is in contact with the sleeve 12 of the tie rod 33. The length of the legs is also selected such that the pressure disk 31 is pressed via the contact surfaces against the anchor plate 34, which is welded to the tie rod 33 in its rear end section.

The spring steel sheet 35' thus takes on the same function as the spring element 35 according to the first embodiment, but does not use the anchor plate 34 but rather the sleeve 12 as an abutment for positioning the pressure disk 31. In this respect, the spring steel sheet 35' or its leg can also be fastened to the outer surface of the pressure disk 31.

Furthermore, the third embodiment shows an alternative solution to the second embodiment with regard to the adjustment control device for the sleeves 12 and 15. The external threads 7 and 8 are coated with a signal color 7b, 8b to a certain length as an unscrewing control, which is covered by the sleeves 12 and 15 when fully unscrewed. When the sleeves 12 and 15 are unscrewed, the coating becomes visible from a certain unscrewing position and thus signals that the minimum screw-in depth has been reached for sufficient tensile or compressive force transmission to the respective tension and compression rods 3a and 4a.

Fig. 4 shows a further, fourth embodiment of the invention.

According to this embodiment, the spring element according to the first embodiment is replaced by a flexible hose 28. As can be seen from Fig. 4, the pressure disk 31 and the anchor plate 34 are covered on their outer surface with the common flexible hose 28, which fits tightly against the pressure disk 31 and the anchor plate 34. The hose 28 can preferably be a rubber material that adheres well to the metallic surface and holds the pressure disk 31 firmly against the anchor plate 34. At the same time, however, the elasticity of the flexible hose 28 allows a relative displacement of the pressure disk 31 and the anchor plate 34 similar to the spring element according to the first embodiment. The advantage of the hose variant is

particularly in its simple assembly and its cost-effective production and processing.

The arrangement of a flexible hose can in principle also be transferred to the adjustment control device. The fourth embodiment provides for the arrangement of a hose, preferably a shrink hose 21' and 15a', at a rear end section of the two sleeves 12 and 15, which are shrunk onto the outer surfaces of the sleeves 12 and 15. The shrink hoses 21' and 15a' thus replace the sleeves used in the first embodiment. Consequently, the shrink hoses 21' and 15a' also have a protective property for the threads 7 and 8 underneath and indicate that the minimum screw-in depths have been reached when the respective external threads 7 and 8 become visible.

According to Fig. 5, a fifth embodiment of the invention provides for the arrangement of a type of disc spring 35'', which is attached to the anchor plate 34 and/or to the tie rod 33 and fixes the movable pressure disk 31 from the inside. The disc spring 35'' has a cylindrical section, which preferably has three axial incisions at one end region (according to Fig. 4, the left end region), whereby three tabs are formed. These tabs are bent radially outwards to form a conically widening section, to the front side of which with a small diameter the cylindrical section is consequently integrally connected. The free ends of the tabs are additionally bent radially outwards, resulting in an interrupted flange extending radially outwards. This flange rests against an end face of the pressure disk 35 (can additionally be attached thereto by soldering, gluing or welding), which faces away from the anchor plate 34, in such a way that the conical and the cylindrical section extend through the through hole of the pressure disk 31 and protrude beyond the end face facing the anchor plate 34.

The inner diameter of the cylindrical section of the disc spring 35'' preferably forms a press fit with the diameter of the tie rod 33, with the anchor plate 34 sitting on the cylindrical section and being fillet welded to the tie rod 33 on its end face facing away from the pressure disc 35''. At the same time, this weld seam also firmly connects the disc spring 35'' to the tie rod 33. The pressure disc 31 is thus pulled against the anchor plate 34 by the disc spring 35'', with the tabs allowing the pressure disc 31 to move at least in the radial direction on the tie rod.

Furthermore, the fifth embodiment according to Fig. 5 provides an adjustment control device in the form of two corrugated pipes or bellows 15a'' and 21'', which can be pushed together and apart in the axial direction of the central pull rod 3a or the push rod 4a. These corrugated pipes 15a'' and 21'' protect the rear section of the external threads 7 and 8 and are fixed to the pull rod 3a or the push rod 4a at one of their end sections. The opposite ends rest on one end face of the sleeves 12 and 15.

If the sleeves 12 and 15 are now turned in the unscrewing direction, the corrugated pipes 15a'' and 21'' move along a predetermined distance according to the compression level with which they are previously pressed together by the sleeves 12 and 15. As soon as the corrugated pipes 15a'' and 21'' are completely relaxed, i.e. have reached their maximum length, the sleeves 12 and 15 move away from the corrugated pipes as they are unscrewed further, whereby the external threads become visible in the gap created. This in turn is the indication that the respective minimum screw-in depths have been reached.
