Description

TECHNICAL FIELD

[0001] The present invention relates to a scaffold, podium or grandstand with at least two scaffold floors that are connected to structurally supporting and laterally contiguous or mutually spaced apart elements, each scaffold floor having the following characteristics: a service surface, two souls attached to the service surface, and connection units arranged frontally for the detachable connection of the scaffolding floor to some structural supporting elements, in particular horizontal crossbars, each soul presenting several recesses that are arranged in the longitudinal direction of the soul in one or several predetermined modular dimensions and the recesses of both souls arranged with complementary symmetry being seen in side elevation.

CURRENT STATE OF THE TECHNIQUE

[0002] Scaffolding floors of the type mentioned at the beginning have already been known for a long time, for example for use in the framework of the already known Layher-Blitz or Layher-Allround scaffolding system. Scaffolding floors have a U-shaped cross section, with souls that are facing down and formed on the two longitudinal side edges. The scaffold floors are hooked frontally on crossbars of the scaffolding system by means of connecting units. Such scaffolding floors are used in large numbers in scaffolding systems and have given good results in the past. [0003] US-A-4984654 describes a multi-part scaffold floor. This multi-part scaffold floor has souls arranged on the left and right longitudinal side edges. The souls have modular recesses arranged displaced in height in the longitudinal direction, being fixedly joined between the recesses, or between the souls, hollow profiles as cross-linking profiles. These hollow profiles serve for the lasting union of both souls and at the same time for the connection of uprights, which is achieved thanks to the fact that the upright presents at its lower end an outgoing elastic profile, which is inserted from the outside into the hollow profile and can bracing by means of an existing plate at the end in combination with a screw that can be screwed from the outside, achieving bracing thanks to the fact that when the plate is pressed against the elastic profile, it widens and braces into the hollow profile. [0004] Document DE 19515062 A discloses a scaffold floor which has in its souls recesses arranged modularly in the longitudinal direction. The recesses are produced by cutting the double-wall core in a U-shape and then folding the U-shape 180 ° by forming in the cut area, in order to mutually join the two wall portions of the double-wall core, thereby that together a greater load capacity can be achieved. [0005] Document DE 1559034 A describes a removable work scaffold, which has two adjacent scaffold floors that can be folded by means of hinges and away from some steps of the vertical stairs located on the front sides or hooked by notches of Hold open down. In the outer souls of the scaffold floor, bolts are provided for the connection of perforated diagonal bars.

EXHIBITION OF THE INVENTION

[0006] Starting from the current state of the art mentioned, the present invention has the objective, or is based on the technical problem, of indicating a scaffold, podium or grandstand that increases the great possibilities of variation in terms of surface configuration of scaffolding floors, or console surfaces, and if necessary allow greater load capacities with less flexion of the scaffolding system as a whole. [0007] The scaffold, podium or platform according to the invention, with scaffolding floors attached to supporting structural elements, is given (a) by the characteristics of the independent claim 1. Of the characteristics of the claims directly or indirectly dependent on the claim 1 advantageous configurations and refinements emerge. [0008] By using scaffolding floors with recesses modularly present in the souls, the variability of the connection possibilities for elements, or profiled connecting bars, or profiled cross-linking bars is considerably increased. In this way connection possibilities are achieved that allow a variability in the configuration of scaffold floor surfaces, a configuration that can also be modified or expanded later, which was not possible with the scaffold floors used to date. [0009] Thus, at least in the area of a recess, a connection unit may be present, which can be detachably connected, or at least one profiled cross-linked bar, arranged so that it crosses recesses with complementary symmetry, for connecting vertical profiled bars or profiled connection bars. [0010] As profiled crossbars, profiled vertical link bars or profiled connecting bars are preferably used hollow profiled bars, in particular round tubular bars.

[0011] At the same time, in a preferred configuration it is possible to create without any problem, by means of connected profiled bars, joints with the other elements of the scaffolding, a rigid bending corner or a diagonal bracing. [0012] By using the scaffold floors described it is also possible to connect a console device, which can be arranged between two scaffold floor planes so that it can be freely adjusted in height. By virtue of a preferred configuration, this is made possible by the fact that the profiled connecting bar forms with the other elements of the structure a rigid bending corner or a diagonal bracing. [0013] A preferred configuration is distinguished in that fixing units are used, which removably fix the profiled cross-link bars in their inserted position. A possible configuration of the fixing unit consists in configuring it as a coupling unit for tubes, being in this case guaranteed at the same time the possibility of connecting an additional vertical joint profiled bar, which can be connected to each other in a statically active way Scaffold flooring floors located above or below. [0014] In order to ensure a secure height fixation of the inserted cross-linked profiled bars, a preferred configuration is distinguished in that the height of the recesses is insignificantly greater than the height of the cross-sectional section of the inserted cross-sectioned profiled bar. [0015] From an economic point of view, it is particularly advantageous to use profiled crossbars having a diameter between 33 and 34 mm (millimeters), in particular 33.7 mm (millimeters), since such profile bars are available at an economical price as series profiled bars in the steel industry. [0016] It is especially advantageous to configure the vertical joint profiled bars as profiled scaffold bars having a diameter between 48 and 49 mm (millimeters), in particular 48.3 mm (millimeters), since in this way, in combination with the recesses of the souls arranged modularly of holes, a possibility of connection compatible with the system for other elements of a scaffolding system can be guaranteed. [0017] Application possibilities, particularly advantageous and economical, are achieved when the scaffolding floor described above is part of a work platform or floor surface. For this, at least two laterally contiguous scaffolding floors are preferably arranged, which are joined together in a statically active manner by means of two profiled cross-linked bars inserted in the recesses spaced mutually spaced in the longitudinal direction. [0018] With respect to an advantageous work floor surface, it is possible to connect a support structure to the bottom of the profiled crossbars, so that, for example, a scissor table is formed. [0019] It is also possible to connect a railing structure to the upper part of the profiled crossbars. [0020] An advantageous configuration is distinguished in that the scaffold is configured as a work platform or floor surface, at least two laterally contiguous scaffold floors being disposed and at least one profiled crossbar, and especially two profiled tie bars. transverse arranged mutually spaced in the longitudinal direction, inserted (s) in the recesses. [0021] With the scaffold floor described above in combination within an application for a system scaffold, a scaffold podium or a podium, a platform or a work floor surface, the particularly advantageous applications described in by way of example: [0022] By inserting profiled cross-link bars it is possible to couple several adjacent scaffold floors together, which for example results in less flexion under load. If fixing units are used at the protruding end of the inserted cross-profiled bars, it is not possible to form any indentation between the different adjacent scaffold floors. In addition, such adjacent floors, coupled with the aforementioned cross-linked profile bars, can be used as a platform. [0023] As profiled crossbars, steel tubes with a diameter of 33.7 mm (millimeters) are preferably used here, which are produced by the large-scale steel industry and therefore constitute a type of profile particularly economical [0024] It is also advantageously possible, simply by passing profiled cross-linked rods configured in particular in the form of the above-mentioned tubes with a length greater than the width dimension of the base system, allowing the possibility of easily fitting from outside onto the bars cross-section profiles other scaffolding floors and, thus, make available console areas, which can also be arranged offset with respect to the existing scaffolding system or covering two scaffolding fields. [0025] The variability is further enhanced by the insertion of profiled cross-linked bars in the recesses of the souls of scaffold floors and the possibility of connecting to these cross-linked profiled bars vertical profiled profiled bars - for example by means of pipe couplings - which, in the same way, can create a possibility of connection with the scaffolding floor (s) above or below. These profile bars of vertical union can then be coupled to console units at any height, being guaranteed by the described configuration of the modular system of the recesses of the souls of the scaffold floors the possibility of easily connecting to the units of An additional scaffolding floor planks connected to the system are connected to the vertical connecting profile bars.

[0026] Another great advantage of scaffolding floors according to the invention is that the weight of each scaffold floor is reduced by means of the cut-off forecast, without this having negative consequences on the static load capacity. Thanks to this weight saving, the ease of assembly and disassembly is greatly increased. [0027] Finally, the recesses arranged in the souls of the scaffold floors constitute a simple possibility of hanging devices that serve for vertical transport or the supply of material (for example a lifting pulley). [0028] In addition, the existing recesses in the souls of scaffolding floors offer a simple possibility (for example using S-shaped connecting devices) to hang or connect tools, material, paint buckets or clothing or other equipment , whose placement on the scaffolding floor in question is not, at least temporarily, advantageous. [0029] The recesses of the souls of the scaffolding floors also allow the possibility of hanging handholds by means of which the scaffolding floor can be hooked or detached more quickly. [0030] Finally, the scaffolding floor according to the invention also offers the possibility of, in superimposed scaffolding floors, reducing the light of scaffold floors by using profiled cross-linked profile bars and profiled bar sections. vertical connection connected to them, especially if the profiled vertical connection bars are housed directly on the ground or the ground, which is advantageous especially in the case of large loads, since in this way the bending is considerably reduced. [0031] It is also possible without any problem to configure rigid bending corners within a scaffolding system, easily connecting a profiled connecting bar to a profiled cross-linked bar inserted in the scaffold floor or recesses and also connecting its another end to the structural elements of the scaffolding, already existing. [0032] It is also possible without any problem to join two or three scaffolding floors coupled by means of profiled cross-link bars to obtain a work surface, which can then be used, for example by a suitable substructure, as a floor surface of work, particularly as a scissor table. [0033] The provision of recesses in the souls of scaffolding floors also offers the advantageous possibility of taking fall assurance measures in almost any position, for example by hooking the fall-insuring belt easily into one of the recesses of the souls. of the scaffolding floor, present in almost all positions. [0034] In order to increase the flexural stiffness and load capacity and reduce the flexion of the different scaffold plates, it is also possible, using profiled crossbars, to connect laterally some reinforcing supports, for example support profiles, which can be easily realized, for example, by means of coupling units for tubes, provided that the supports to be reinforced are configured as tubes. [0035] Finally, it is easily possible to use the laterally projecting end of the profiled tie bars inserted in the recesses of the scaffold floors for the connection of railings or the fixing of shelves. [0036] As already mentioned, the most diverse shapes can be used for the internal contour of the recesses. The possibility of mixing different forms of holes and modules of holes allows to optimally take advantage of the connection of other structural elements by applying the possibility of numerous insertion options in the longitudinal direction of the soul of the scaffold floor. With the scaffolding floor according to the invention, it is possible to make floors in metric measurement and, for example, in the system measurement of the already known Layher "Blitz" and "Allround" scaffolding systems. At the same time, the described scaffolding floor can be used in different scaffolding systems, for example depending on the configuration of the connection units as connection claw units to engage in open U-profiles upwards, to engage in round tubes or to hook on spikes. [0037] Additional features and advantages of the invention follow from the features mentioned further in the claims, as well as from the embodiments indicated below. The characteristics of the claims can be combined with each other at will, provided they are not mutually exclusive in an obvious way.

EMBODIMENTS OF THE INVENTION

[0039] In figure 1a a scaffolding floor 10.4 is shown schematically in perspective, which, according to figure 2, has an essentially U-shaped cross section, with a service surface 12 with holes 13 located at the top and some souls 14 that are formed on the longitudinal side edges and oriented downwards. [0040] At the respective front ends, front end plates 15 facing down are formed, to which two connection units 16 having an L-shaped cross-section with one of the arms facing down are connected. Such connection units 16 serve to engage the scaffold floor 10.4, for example, in a horizontal crossbar of a scaffolding system having a cross-sectional profile in the form of an upwardly oriented U. [0041] In each soul 14 there are through recesses 20, 22 with a closed inner peripheral contour. Of these, first recesses 20 have a circular inner peripheral contour with the diameter L1 or H and second recesses 22 have height H and length L2. [0042] The recesses 20, 22 are arranged symmetrically with respect to the longitudinal center, in a predetermined module in the longitudinal direction of the soul. The first two recesses 20 arranged symmetrically with respect to the center have a modular adaptation dimension A. The first and second recesses 20, 22 that follow these in the direction of the front end are arranged in the modular dimension R. At the same time , a first round recess 20 always appears alternately and then a second oblong recess 22 and so on. [0044] The recesses 20, 22 shown are exemplary embodiments. There may also be recesses that have a polygonal inner peripheral contour, for example in the form of a square or rectangle. [0045] In Figure 1b the end of the scaffolding floor 10.4 is shown, to whose front face 15 a connection unit 17 is connected which has a through recess 19 at each of its two ends and, therefore, can be engaged. on existing spikes in the scaffolding system. Figure 1c shows the end of the scaffold plank 10.4 with two connection units 18 that are connected to the front face 15, have a circular segment-shaped contour in cross-section and, therefore, are suitable for engaging them in tubular profiles round. [0046] As shown in Figure 2, recesses 20, 22 can be easily produced by punching. In this case, the wall of the soul extends straight to the recess 20, 22, according to the exemplary embodiment of Figure 2. [0047] However, it is also possible to provide a reinforcement of the cross-section in the contour of each recess. . In FIGS. 3a to 3c, possible embodiments of a cross-section reinforcement of this type are shown, which is preferably produced by cold forming. According to Figure 3a, the cross-sectional reinforcement has been carried out by directly stamping a convexity 42 on the wall of the core, along the entire edge of the cutout 20. In Figure 3b, a cut-out edge has been stamped on the edge of the cutout. convexity 44 which is at a certain distance from the recess 20, that is to say that from the area of the convexity 44 to the edge of the recess there is a wall section 46. According to Figure 3c, in this exemplary embodiment the cross-sectional reinforcement it has been performed by causing the wall of the soul to present a bend 48 at the peripheral edge of the recess 20, such that the bend 48 is slightly inclined inward. [0048] In figures 4a to 4e, scaffold floors 10, 10.1, 10.2, 10.3, 10.4 are shown in a side view that have different system lengths and respectively have the same system of modular dimensions, with modular dimensions A for the first two inner recesses 20 and R for the other recesses 20, 22, the first and second recesses 20, 22 alternating in the longitudinal direction also appearing here. The difference in length between the scaffold floors 10, 10.1, 10.2, 10.3, 10.4 represented is such that, starting from the scaffold floor 10 according to Figure 4e, each other scaffold floor shown above has a greater length as far as one Modular dimension of predefined SR system. [0049] As shown in Figure 4a, the recesses module 20, 22 is summed up in such a way that there are spaced recesses 20, 22 whose separations correspond to the system dimensions S1, S2, S3, for example of a system scaffolding. [0050] In the embodiment shown, the modular dimension A is 197 mm (millimeters) and the modular dimension R is 125 mm (millimeters). The modular dimensions S1, S2 and S3 are 1,572, 2,072 and 2,572 mm (millimeters). The modular dimension of the SR system is 500 mm (millimeters). [0051] By means of the configuration of the recesses in the system of modular dimensions represented and the forecast of oblong holes it is possible to realize the most diverse lengths of system for the connection of structural elements of system, which offers great advantages especially as regards the Application variability of such scaffolding floors within a scaffolding system. This is especially applicable in the event that a coupling is made through additional structural elements through scaffolding floors, as will be described later. Thus, it is no problem to realize the system dimensions of the already known Layher-Allround or Layher-Blitz scaffolding system, nor to use scaffolding floors whose system dimensions are based on a metric system. [0052] In figures 5 to 8 the coupling of scaffold floors 10, 10.1 to 10.5 arranged laterally adjacent is described by way of example. Figure 6 shows a top view of the scaffold floor surface of a system scaffold. The normal scaffolding field has vertical uprights 24 and horizontal crossbars 26 that join together the vertical uprights 24 (connections not shown in detail) and in which the scaffolding floors 10 are engaged by means of their connection units 16. The surface of scaffolding formed by the two 10.3 scaffolding floors can now be easily expanded with scaffold console surfaces. For this purpose, profiled crossbars 30, which, in the inserted position, protrude laterally from both scaffold floors 10.3, are passed in the corresponding places, in the transverse direction, through the corresponding recesses 20, 22. Two scaffolding floors 10 (in figure 6, represented in the upper left) and two scaffold floors 10.2 (in figure 6, represented in the part, are fitted from outside the protruding crossbar 30). lower right), that is to say that the profiled cross-linked bars 30 are introduced into the corresponding recesses 20 or 22 of the scaffold floors 10 or 10.2. The profiled cross-link bars 30 also have a protruding end on both sides to which fixing units can be detachably connected, which prevent the formation of a groove between the embedded scaffold floors 10 or 10.2. The cross-linked profiled bars 30 also have the effect that the existing scaffolding floors 10.3 of the existing system scaffold act in a statically co-supporting manner, that is, if only one scaffold floor 10.3 is loaded, the one located at its side absorbs the load together, which results in a reduction in flexion. [0053] As profiled cross-link bars 30, for example, round steel tubes having a diameter of 33.7 mm (millimeters), which is a common diameter in the sector of steel profiles, can be used. At the same time, the recesses 20, 22 have a height H that is insignificantly greater than the diameter of the profiled cross-linked bars 30 inserted. [0054] The fixing units 40 may preferably be configured as coupling units for pipes, which will be used in large quantities in the construction of scaffolding and at the same time offer the possibility of allowing, in addition to the fixing of adjacent scaffolding floors, the connection of other profiled scaffolding elements. [0055] In figure 5 the connection of scaffolding floors 10 to a scaffold floor 10.3 with different longitudinal displacements is schematically represented, in a side view, with scaffold floors 10.3 being arranged in figure 5 one below the other. , 10 adjacent. The recesses 20, 22 corresponding to each other, through which a profiled crossbar can be introduced respectively, are schematically linked with arrows P. [0056] Figure 8 shows, by way of example, another embodiment of the configuration of console surfaces by means of the lateral fit of scaffold floors 10.2, 10.3 on profiled cross-linked bars 30 inserted in the existing scaffold floors 10.4. With this, it is also possible to achieve surface extensions of scaffolding floors, which extend, at least partially, through two scaffold fields (in figure 8, represented at the bottom). [0057] Figure 7 shows, in a manner similar to Figure 5, the arrangement of adjacent scaffold floors with different longitudinal displacements, which are partly extended by two scaffold fields, also being arranged here displaced in height in the representation of adjacent scaffolding floors. The recesses 20, 22 corresponding to each other, through which a profiled crossbar can be introduced respectively, are schematically linked with arrows P. [0058] A detail of a system scaffold is shown in Figure 9, as for example, the Layher-Blitz scaffolding system, in which structural frame elements with vertical uprights 24 and horizontal crossbars 26 are used. In total three floors of scaffolding floors are represented. Each floor of scaffolding floors will be formed by two 10.4 scaffolding floors hooked on horizontal crossbars 26. By means of the recesses of the souls 14 of the scaffolding floors 10.4 they have passed respectively through the two adjacent scaffold floors 10.4, in the floors of floors of upper and central scaffolding, approximately at the points located one third and two thirds of the length, two profiled crossbars 30 protruding laterally slightly forward. In this projecting area, a profiled vertical bar 32 is connected respectively to the profiled crossbar 30 of the upper and central scaffold floor floors, by means of coupling units not shown in detail. By means of these two profiled vertical connecting rods 32, a supporting structure is made available to which, as shown by way of example in Figure 9, other scaffolding elements can be connected as, in the case in question, console units 38. The vertical joint profiled bars 32 are standard scaffolding tubes and, given the geometry of the modular dimension of the recesses of the scaffold floors 10.4, they are arranged in the dimension of scaffolding system S2 in the longitudinal direction. In this way it is possible to easily and smoothly hook a system scaffolding floor 10 into the two console units 38. A great advantage of this design is that the console units 38 can be connected at virtually any height (arrow h) between the floors of upper and central scaffolding floors. [0059] On the floor of lower scaffold floors, two scaffold floors 10.4 are also hooked on the horizontal crossbars 26. At points one third and two thirds of the length have passed through the recesses of the floors of Scaffolding 10.4, cross-section profiles 30, which protrude forward and form a cantilever support. Two other 10.4 scaffolding floors have been fitted on this projecting area, so that a console surface corresponding to the surface of the scaffold floors within the system scaffold is obtained. At the remaining projecting end of the profiled cross-link bars 30 there are fixing units, not shown in detail in Figure 9, whose purpose is to prevent crevices from forming between embedded scaffold floors. [0060] In figure 10 a detail of a scaffolding system is shown in a side view in which on each scaffold floor 10.4, seen in a vertical line, a profiled cross-linked bar 30 is inserted through the corresponding recesses, being connected to its protruding end, at each level of scaffold floors, a profiled vertical connecting bar 32 that reaches the ground. In this way, the light of the respective scaffolding floors 10.4 is divided into two approximately equal parts, which results in a greater load capacity and less flexion under load. [0061] Figure 11 differs from the representation according to figure 10 in that in this variant embodiment three total vertical profile bars 32 are connected to the cross section profile bars 30. [0062] Figure 12 shows schematically depicted the connection of a profiled connecting bar 34 configured as a diagonal bar, which is also connected by profiled cross-linked bars 30 that are inserted in their corresponding position in the scaffold floor 10.4. [0063] Figure 13 shows the possibility of creating rigid bending frame corners by means of inclined profiled connecting bars 34, which are respectively connected to a profiled cross-sectional bar 30 and a vertical post 24. [0064] Figure 14 shows a perspective of a detail of the configuration of a scaffold floor surface between two lattice beams 50, in a first embodiment variant. Between the two lattice beams 50, four scaffolding floors 10.4 extending parallel to the upper bead 52 are arranged laterally adjacent to the height of the corresponding upper bead 52 and are coupled to each other by two profiled cross-linked bars 30 arranged approximately in the points located one third and two thirds of the length. The ends of the profiled cross-link bars 30 are connected to the upper cord 52 of the corresponding lattice beam 50 by means of connecting units 54, schematically represented. The connection units 54 may be, for example, coupling units for tubes, provided that the upper bead is configured as a tubular profile. [0065] In Fig. 15 another variant embodiment is schematically shown in perspective for the configuration of a scaffold floor surface between two lattice beams 60. Scaffold floors 10.4, arranged at the height of the corresponding upper cords 62 between the two lattice beams 60 separated, extend perpendicularly to the upper bead 62 and are easily engaged by their connection units in the upper bead 62, which is configured as a U-profile open upwards. Approximately at the points located at one third and two thirds of the length are inserted through the recesses of the souls of the scaffold floors 10.4, parallel to the lattice beam 60, profiled cross-linked bars 30 that join the floors 10.4 adjacent scaffolding forming a joint platform. In this design, the loads that are presented on a 10.4 scaffold floor are also not absorbed only by this scaffold floor, but are diffused to adjacent 10.4 scaffold floors. [0066] Figures 16a and 16b schematically show, in cross section, a possibility of easily increasing the loading capacity of a 10.4 scaffold floor. For this purpose there are support profiles parallel to the longitudinal edge of the scaffold floor 10.4, which, according to Figure 16a, can be configured as a profile in I 70 or, according to Figure 16b, as a tubular profile 72. In order to use The profiles 70, 72 for the static joint support under load, are passed through the recesses 20 of the souls 14 of the scaffold floor 10.4 at least one profiled crossbar 30, whose corresponding end joins the profile in I 70 or to the tubular profile 72. For this purpose connection units 74.1 and 74.2 are used which are adapted to the corresponding geometry of the profile 70, 72 in question. [0067] A detail of a scaffolding system is schematically shown in Figure 17, in which also profiled vertical link bars 32 are connected to profiled crossbars 30, similar to the embodiments shown in Figures 10 and 11. However, here the profiled connecting rods 32 do not reach the floor area, but instead join three floors of overlapping scaffold floors, so that a load that is present on a floor of scaffold floors It is distributed on three floors of scaffolding floors. In contrast to the representation of Figure 10, two separate vertical profiled bars 32 are also used here. The vertical link profile bars 32 are connected to the cross profile profile bars 30 both at the front and at the back of the system scaffolding. [0068] Figure 18 schematically shows the configuration of a platform, which in the exemplary embodiment is formed by five adjacent scaffold floors 10.4, a total of four profiled cross-linked bars 30 being inserted into the recesses of the souls 30 in a relatively narrow module. The means for detachably fixing the profiled cross-link bars 30 in their inserted position are not shown in detail in Figure 18. [0069] Figure 19 schematically shows the configuration of a so-called scissor table in the that, as a work floor surface, two adjacent 10.4 scaffold floors are provided, for example. At the end and at points one third and two thirds of the length, a total of four profiled crossbars 30 are inserted through the recesses of the scaffold floors 10.4, so that the two scaffold floors Adjacent 10.4 act as a platform. [0070] To the two profiled cross-sectional outer bars 30 is connected, by means of coupling units for pipes not shown in detail, a vertical bar 80 that rests on the ground. To stabilize the scissor table there are two diagonal bars 82 which, together with the scaffolding floor 10.4 and the vertical bar 80, respectively form a rigid corner to bending. The diagonal bars 82 are respectively connected, at the top, to the profiled cross-link bars 30 inserted at the points located one third and two thirds of the length and, at the bottom, to the lower end of the vertical bar 80 [0071] Figure 20 schematically shows the easy connection of a railing structure 84, composed of vertical uprights 86 and horizontal crossbars 88, to a scaffold floor 10.4 provided with recesses in the

5 souls, easily connecting the vertical uprights 36 to the protruding end of a profiled cross-link bars 30 inserted in the recesses of the scaffold floor 10. [0072] The inserted cross-section profiles can also be used as protection against lifting for flooring scaffolding, joining the profiles fixedly to the ground by means of connected elements. [0073] In figure 21 two 10.5 steel scaffolding floors are shown, which are arranged one after

10 and have respectively an modular dimension of increased adaptation AS and three recesses 20, 22 respectively arranged in a modular dimension R at the points located one third and two thirds of the length. [0074] In the embodiment shown, the modular dimension is 1,197 mm (millimeters) and the modular dimension R is 125 mm (millimeters). The modular dimension AS can be calculated according to the formula 197 mm

15 + n * 250mm, siendon = 0,1,2,3, .... [0075] Below is a 10.4 scaffold floor, which is arranged laterally offset with respect to the two 10.5 scaffold floors and coupled to these last by means of profiled cross-linked bars not shown in detail. The recesses 20, 22 corresponding to each other, through which a profiled crossbar can be introduced respectively, are schematically linked

20 with arrows P. [0076] The forecast of only three recesses 20, 22 in the area of the points located one third and two thirds in length allows relatively high load capacities for the 10.5 scaffold floor, achieving no However, at the same time, the variable connection possibilities offered by the recesses.
