Fig. 1 shows only a small part of a scaffold. Stems 30 carry perforated disks 31, which are known per se, at a distance from one another which corresponds to the grid dimension of the scaffolding system. A support bar 32 is fastened to the perforated disks 31 between the stems 30 by means of wedge heads 35 . For this purpose, wedges 34 penetrate the perforated disks 31 and the wedge heads 35 . The support bar 32 is designed as an upwardly open U-profile. The upper ends of the vertical legs 37.1 and 37.2 of the support bar 32 are designed as support edges 38 for the hooking means forming hooks 46.1 , 46.2 , 46.3 of the scaffolding floor 45 . The wedge heads 35 are designed in a known manner with horizontal slots and put on the perforated disks 31 and secured to them with the wedges 34 . In this or a similar way, many scaffolding days are realized in one scaffold. This section is only shown to illustrate how the scaffold floors with their designs are arranged throughout the scaffold. Instead of a scaffold with stems and modular node connections, frame scaffolds can also be provided.

As shown in FIGS. 1 and 2 show, the selected here as an example scaffolding floor 45 has three hooks 46.1, 46.2, 46.3 narrow at the two end faces. These are fastened by welding to the stable cross-connection cap 54 made of sheet steel, as is evident from the following drawings and the associated descriptions. The suspension jaws 47 of the suspension hooks 46.1 , 46.2 , 46.3 reach over the vertical legs 37.1 , so that the respective scaffold floor is supported on the support edge 38 of the support bar 32 . A second scaffold floor (not shown) can be supported on the vertical leg 37.2 .

Figs. 1, 2 and 3 show a single frame bottom 45. This consists of several profile parts. The two edge- bottom profile parts 48.1 and 48.2 are connected to the bottom-center profile part 49 along the center seams 51 , 52 . Cross-connection caps 54 designed as cross reinforcement profiles are connected together with the hooks 46.1 , 46.2 , 46.3 to the edge- bottom profile parts 48.1 , 48.2 and the bottom-center profile part 49 in the manner described in more detail with reference to the further drawings. Instead of the embodiment described in more detail here with a plurality of floor profile parts 48.1 , 48.2 , 49 , however, the scaffold floor 45 can also be formed with only a single floor profile part.

The scaffold floor 45 has, as illustrated in FIGS. 1, 2 and 4.1, a longitudinal profile in partial regions 56 tread 55, wherein alternating smooth with these longitudinally extending portions 57 of the tread 55 are provided. The longitudinally profiled partial areas 56 of the tread 55 formed with longitudinal ribs 63 ( FIGS. 7, 11.1 to 11.3) enable a non-slip surface. For this purpose, can also bulges in Figures 11.1 to 11.3 shown in more detail, the edge configurations, and the like contribute, whereby openings or holes may be provided with raised edges -.. As described in more detail in connection with the discussion of Fig 11.1 to 11.3..

On the underside of the scaffold floor 45 , as can be clearly seen in FIG. 4.1, cross-sectionally shaped longitudinal reinforcing bars are integrally formed, in the exemplary embodiment the two edge bars 58.1 , 58.2 and the central bar 59 as well as the longitudinal seam connecting elements 61 , 62 as Auxiliary reinforcement structures are formed in one piece with the respective floor profile part. As can be seen, there is an integral surface part and frame structure of great stability with regard to bending, twisting and twisting.

The hooks 46 are designed in the usual manner, being designed respectively to guarantee a secure support of the two lateral hooks 46.1 and 46.2 of the middle hooks 46.3 in such a manner fixed relative to the hooks 46.1 and 46.2 that this edition of the suspension hooks at 46.1 and 46.2 on the support edge 38 of the vertical leg 37.1 of the support bar 32 has not yet touched the support edge 38 .

The profile of the cross-connection cap 54 results above all from FIGS. 4.2, 4.3 and 5.1 to 5.3. It has a horizontal thigh 66 , a horizontal lower leg 67 , a vertical outer wall 68 and on both sides vertical side legs 69 and the following connection conditions, which are also designed to match the hook design. In the vertical outer wall 68 of the cross-connection cap 54 , two horizontally extending, outwardly curved beads 70 are each arranged at a distance 71 from the side legs 69 and at a distance 72 from the lower leg 67 . The width 73 of the beads 70 is slightly larger than the width 74 of the hooks 46 .

The thigh 66 , the lower leg 67 and the side legs 69 are each bent on the same side relative to the vertical outer wall 68 at an angle of 90 °, so that there is a U- or C-shaped cross-sectional profile. As a result, the lower leg 67 is formed parallel to the thigh 66 and normal to the vertical outer wall 68 and the side legs 69 are also parallel to one another and in each case normal to the vertical outer wall 68 and normal to the lower leg 67 and the thigh 66 . The corner transitions between the vertical outer wall 68 and the thigh 66 , the lower leg 67 and the side legs 69 are each rounded. The thigh 66 has a depth 76 which is the same as the depth 77 of the lower leg 67 . The respective front outer edge 83 of the thigh 66 has a distance 84 from the outer surface 85 of the side leg 69 which is greater than the distance 87 ( FIG. 6.2) of the inner surface 88 of the outer spar wall 89 of the side rails 58 from the inner edge 91 at the transition between the displacement limiting rib 92 and the tread 55 .

The respective end outer edge 93 of the lower leg 66 has a distance 94 from the outer surface 85 of the side leg 69 that is greater than the distance 84 from the outer surface 85 of the side leg 69 . The side legs 69 have a width 96 which is smaller than the distance 97 between the inner surface 98 of the upper spar wall 101 of the edge spar 58 and the inner surface 99 of the lower spar wall 102 of the edge spar 58 . The upper edge 103 of the side leg 69 has a distance 107 from the inner surface 105 of the thigh 66 which is the same as the distance 108 between the lower edge 104 of the side leg 69 and the inner surface 106 of the lower leg 67 . The distances 107 , 108 are greater than the thickness 109 of the upper spar wall 101 , 153 or the upper wall 111 , 151 of the edge-bottom profile part 48 or the bottom-center profile part 49 ( FIG. 7, 10.2) having the longitudinal ribs 63 . The thigh 66 , the lower leg 67 and the side leg 69 have the insertion bevels 78 , 79 , 80 in their inwardly facing corner regions. These are designed to be chamfered by an angle of 45 ° or 135 ° with respect to the respective outer edges of the thigh 66 , the lower leg 67 or the side leg 69 .

The inner surface 105 of the thigh 66 is at a distance 113 from the inner surface 106 of the lower leg 67 which is the same size or slightly larger than the distance 116 of the tread 55 from the lower surface 117 of the lower spar wall 102 of the edge spars 58 ( FIG. 4.3) or the lower surface 118 of the lower spar wall 126 of the central spar 59 . The outer surfaces 85 of the two side legs 69 are at a distance from one another which is the same size or slightly smaller than the distance between the inner surfaces 88 of the outer spar walls 89 of the edge spars 58.1 and 58.2 .

Due to the measures described above, the cross-connecting cap 54 may be on or in with the edge-floor section parts 48.1, 48.2 and the bottom-middle profile part up 49 formed scaffolding floor structure of the framework floor 45 and are pushed until the inner surface 122 of the vertical Outer wall 68 strikes in the area of the outward-facing end edge 123 of the tread 55 or the end edges 124 of the lower spar wall 102 of the edge spars 58.1 , 58.2 or the end edge 125 of the lower spar wall 126 of the center spar 59 . The thigh 66 overlaps the running surface 55 and the lower leg 67 overlaps the lower surfaces 117 and 118 of the side rails 58.1 , 58.2 and the lower surface 118 of the center rail 59 . In contrast, the side legs 69 are pushed into the side rails 58.1 , 58.2 in the assembled state, so that the outer surfaces 85 of the side legs 69 lie opposite the inner surfaces 88 of the outer rail walls 89 of the side rails 58.1 , 58.2 . Instead of the embodiment described above, the cross-connection cap 54 can also be inserted with its thighs 66 and / or its lower legs into the scaffold floor structure of the scaffold floor 45 . The thigh 66 engages under the tread 55 and the lower leg 67 engages under the inner surfaces of the edge bars 58.1 , 58.2 and the center bar 59 or rest there. For this purpose - depending on the embodiment - either the thigh 66 and / or the lower leg 67 with the distance and the thickness of the vertical spar walls 159 ; 154.1 , 154.2 suitably designed and extending to the inner surface 122 of the vertical outer wall 68 slots and / or the vertical spar walls 159 ; 154.1 , 154.2 are provided with slots designed to match the wall thickness 144 and the depth 76 or 77 of the thigh 66 and / or the lower leg 67 . By inserting and designing the cross-connection cap 54 into the scaffolding floor profile structure with the cross-sectionally closed box-shaped longitudinal reinforcement profiles, in contrast to all-round welding, the formation of hollow chambers in which condensed water can collect is avoided.

In the vertical outer wall 68 of the cross-connection cap 54 , position holes 142 are provided at suitable locations, which serve to position the cross-connection cap 54 during the manufacturing process. These also allow the hanging of the hanging hooks 46 provided with the cross-connection cap 54 in the surface coating or in the transport of associated with the cross-connecting caps 54 scaffolding floors 45, for example by means of transport elevators.

The hooks 46 are welded to the cross-connection cap 54, for example using a suitable auxiliary device, on the vertical outer wall 68 of the cross-connection cap 54 . The exact height position of the side hooks 46.1 and 46.2 is determined in such a way that they are placed with their rear bearing surface 145 below the bead 70 on the vertical outer wall 68 and are moved upwards until they are in their upper boundary surface 146 rest on the bead 70 . The hooks 46 formed from sheet steel by means of forming are protected against moisture-related aging after welding with the cross-connection cap 54 made from sheet steel in a suitable surface coating method, in particular by galvanizing.

The fastening of the cross-connection cap 54 is made at the bottom profile structure of the framework floor 45 in the exemplary embodiment by means of suitable small joining means, preferably rivets, in particular blind rivets, 127, 128, 129, so that a metallschmelzflußfreie or hot joining processes free compound is formed. The blind rivets 127 , 128 , 129 are inserted through through bores 121 provided at suitable points in the cross-connection cap or the floor profile structure and are subsequently shaped or deformed using a conventional shaping process. This results in a connection of the cross-connection cap 54 to the floor profile parts of the scaffolding floor 45 which is very economical in terms of time and costs, without any welding processes being necessary for this. Furthermore, a self-repair that may need to be carried out is simple and inexpensive.

The attachment of the cross-connection caps 54 to the scaffolding floor profile structure of the scaffolding floors 45 with the aid of blind rivets can be seen in particular from FIGS . 10.1 and 10.2. There are three blind rivets 127.1 , 127.2 , 127.3 penetrating the upper leg 66 and the upper spar walls 101.1 , 101.2 , 153 and four the lower leg 67 of the cross-connection cap 54 and the lower spar walls 102.1 , 102.2 , 126 of the longitudinal reinforcing spars rivets 128.1 , 128.2 , 128.3 , 128.4 are provided. Furthermore, other fastening options are also created by connecting the outer spar walls 89 of the edge spars 58.1 and 58.2 to the side legs 69 of the cross-connection caps 54 which are inserted on the inside. For this purpose, the two blind rivets 129.1 , 129.2 are provided, which are each arranged vertically one above the other in the outer spar walls 89 in the area between the two abutment surfaces 165 and 167 . This results in a further improved stability of the surface part and frame structure, in particular with regard to twisting and twisting.

The two blind rivets 128.2 and 128.3 are arranged in the lower spar wall 126 of the central spar 59 symmetrically to the transverse axis of symmetry 130 . The two blind rivets 128.2 and 128.3 find sufficient space in the wide lower spar wall 126 of the central spar 59 , the arrangement and positioning of these two blind rivets 128.2 and 128.3 being advantageous from the point of view of strength and assembly. The blind rivets 128.2 and 128.3 are further arranged so spaced that, in the stacking of the scaffold platforms 45.1, 45.2 shown in FIG. 10.1 is sufficient space for the blind rivet 127.2 in the transverse center of the underlying framework floor 45.2. The blind rivets 127.1 and 128.1 or 127.3 and 128.4 arranged in the area of the edge rails 58.1 and 58.2 of the scaffold floors 45.1 and 45.2 are also offset in the transverse axis direction of the scaffold floors 45 . This creates a scaffold floor that is optimized for transport height.

The exact engagement conditions in the area of the side rails 58.1 when the scaffold floors 45 are stacked can be seen from FIG. 10.2. Thereafter, when the respective upper scaffolding floor 45.1 with the rivet heads 132.1 , 132.2 , 132.3 , 132.4 of the lower blind rivets 128.1 , 128.2 , 128.3 , 128.4 is stacked , it rests on the thigh 66 of the cross-connection cap 54 of the scaffolding floor 45.2 below. Accordingly, the upper scaffold floor 45.1 also rests with the lower leg 67 of its cross-connection cap 54 on the rivet heads 131.1 , 131.2 , 131.3 of the blind rivets 127.1 , 127.2 , 127.3 of the lower scaffold floor 45.2 .

The wall thickness 81 , 82 , 86 of the wall parts forming the scaffold floor profile parts is essentially the same ( FIGS. 7, 10.2). The cross-connection cap 54 has an essentially constant wall thickness 144 , which here is approximately 75% of the wall thickness 81 , 82 of the wall parts forming the scaffold floor profile parts. The rivet head height 133 corresponds approximately to the wall thickness 144 of the cross connection cap 54 .

The overall structure of the individual floor profile parts can best be seen in FIGS. 6.1 and 6.2. Fig. 6.1 shows the symmetrically shaped to the transverse axis of symmetry 130 bottom middle profile part 49. This has the central spar 59 , the top wall 151 formed with the tread 55 and the two cross joint connection element parts 155.1 , 155.2 formed on the cross ends 152.1 and 152.2 . The bottom-center profile part 49 is formed in one piece with the center bar 59 . The central spar 59, which is designed as a longitudinal reinforcing spar, is formed with the upper spar wall 153 , the lower spar wall 126 and the two side spar walls 154.1 and 154.2 which run obliquely inwards downward, so that a box-shaped or trapezoidal, cross-sectionally closed reinforcing profile is formed, that is designed without any structural elements that may weaken the material structure, in particular without longitudinal seam connecting elements.

Fig. 6.2 one of the two identically shaped edge is ground profile portions 48. This is formed with the upper wall 111 containing the tread 55 , the edge rail 58 and the transverse butt joint element part 156 arranged at the opposite transverse end 155 . The reinforcing bar designed as a longitudinal spar 58 is formed with the horizontal upper spar wall 101 , the horizontal lower spar wall 102, the vertical outer spar wall 89 and the inner spar wall 159 . This has a C-shaped or V-shaped rear spar wall rear grip profile 110 which engages behind the lower spar wall 102 and which forms the handle recess 120 which is designed to be easy to handle. This enables the scaffolding floor 45 to be secured against slipping and ergonomically when carried by hand, even when wearing gloves.

The inner spar wall 159 is formed with the two part spar walls 161 and 162 . The upper partial spar wall 161 extends from the inner end 114 of the upper spar wall 101 obliquely downwards and outwards. It forms an angle 136 with the upper spar wall 101 . The lower part-spar wall 162 extends from the inner end 115 of the lower-spar wall 102, which is also rounded off from the point of view of handling safety, and extends obliquely upwards and both part-spar walls 161 , 162 go into one another, forming the longitudinal edge 163 about. The lower partial spar wall 162 forms an angle 137 with the lower spar wall 102 which is larger than the angle 136 . The two angles 136 and 137 have been optimized with regard to handling and stress conditions.

These measures enable safe gripping when transporting the scaffolding floor by hand, even with gloves, as well as additional stiffening of the side rails 48.1 , 48.2 and a reduced risk of buckling. The two partial spar walls 161 , 162 are designed over the entire length of the scaffold floor with the flat and relatively smooth partial surfaces 147 , 148 . This facilitates the handling of the scaffolding floors 45 and reduces the risk of injury. In addition to the measures described above, the width 139 of the lower spar wall 102 is designed to be securely gripped when the scaffolding floors 45 are transported with the human hand, even with gloves, to which the arrangement and design of the centering rib 164 also contribute.

The upper spar wall 101 has a width 138 which corresponds to the width 139 of the lower spar wall 102 . The upper spar wall 101 has in the outer edge region an upwardly extending displacement-limiting rib 92 which, when the scaffolding floors are stacked, as in FIGS . 10.1 and 10.2, with that in the region of the lower outer edge of the edge spar 58 provided centering rib 164 corresponds. This centering rib 164 , which is designed as a partial cylinder rib, has the outer abutment surface 165 . At the upper end of the outer spar wall 89 , the corner rib 166 is provided. This has the outer abutment surface 167 , which lies in the same plane as the outer abutment surface 165 of the centering rib 164 .

The exact design of the cross joint connection element parts 155.1 and 155.2 and 156 results from FIG. 7, in particular from FIGS. 8.1 and 8.2. The cross joint connection element part 155 is shown in FIG. 8.1. This is designed with a spring-connection element 170 which is T-shaped in cross section and which, in the assembled state - as can be seen in FIG. 7 - with the groove connection connection which is designed as a cross joint connection element part 156 and has a hook-shaped cross section. Element 200 is engaged. As can be seen from FIG. 8.1, the spring connection element 170 is connected in one piece to the top wall 151 of the bottom-center profile part 49 . It is formed with the outwardly extending diagonal web 171 , the outwardly facing horizontal web 172 and the downwardly extending vertical web 173 arranged centrally on this. In the area of the diagonal web 171 , the keyway 176 is formed between the top wall 151 and the horizontal web 172 . This is delimited by the wedge surface 174 which runs obliquely inwards and the upward-facing contact surface 175 of the horizontal web 172 . The horizontal contact surface 175 of the horizontal web 172 is at a slight distance 168 from the lower surface 177 of the upper wall 151 . Starting from the keyway 176, the horizontal contact surface 175 runs parallel to the scaffold floor transverse axis 169 and consequently parallel to the running surface 55 or the top wall 151 . The horizontal web 172 is formed at its free end 178 with the spring part 180 . This is limited at the top by the contact surface 175 and at the bottom by the conical surface 182 and is designed at the free end 178 with the insertion radius 181 . The cone surface 182 is inclined at an angle 183 with respect to the scaffold floor transverse axis 169 or with respect to the contact surface 209 of the groove-connecting element 200 corresponding to it in the assembled state, so that the insertion bevel 184 is formed. The horizontal web 172 has a depth 185 and the spring part 180 of the horizontal web 172 has a maximum insertion length 186 . At the inner end 187 of the spring part 180 , the connecting part formed with the vertical web 173 is arranged. At its lower end 179, this has the welding flap 190 formed with the material accumulation 189 . The vertical web 173 has a depth 193 in a region formed with the parallel vertical surfaces 191 and 192, which depth is designed in accordance with the selected joining method. The welding flap 190 has the lower inclined surface 194 , which forms an angle 195 with the vertical surface 191 of the connecting part 188 , which here is approximately 60 °. The connecting part 188 has the depth 196 .

The horizontal web 172 is delimited in the area between the connecting part 188 and the diagonal web 171 by the horizontal lower surface 197 , which is formed parallel to the horizontal contact surface 175 . The diagonal web 171 adjoining the horizontal web 172 inwards at the top has the inclined surface 198 .

All corner transitions of the cross joint connection element part 155 , 156 are designed with radii optimized for material and stress, with the exception of the transition part 157 of the top wall 151 , which is formed with the relatively tapered edge 158 .

In Fig. 8.2 of the transverse joint connecting-element part 156 is shown with the hook-shaped in cross-section groove connecting element 200. This is formed with the horizontal top wall part 202 , the diagonal web 203 , the horizontal rear gripping web 204 and the essentially vertical connecting part 205 . The top wall part 202 has at its free end 206 the wedge surface 207 which, in the assembled state, abuts the wedge surface 174 of the spring connection element 170 ( FIG. 7). The top wall part 202 is rounded at its free end 206 with the radius 208 . The upper wall part 202 is delimited on its underside with the horizontal contact surface 209 . The horizontal contact surface 209 of the horizontal top wall part 202 is at a slight distance 149 from the bottom surface 112 of the top wall 111 .

The top wall part 202 has a depth 210 which is greater than the depth 185 of the horizontal web 172 of the spring-connecting element 170 . The diagonal web 203 is formed at the inner end 231 of the top wall part 202 . This is delimited on its side pointing towards the edge rail 58 by the inclined surface 211 and delimited on its side pointing towards the free end 206 of the top wall part 202 by the vertical surface 217 . The diagonal web 203 merges into the horizontal rear engaging web 204 , the transition being designed with the relatively large radius 212 . The rear grip web 204 is delimited by the support surface 213 and the outer surface 214 parallel to it. The groove 215 is formed between the contact surface 209 of the top wall part 202 , the vertical surface 217 of the diagonal web 203 and the horizontal support surface 213 of the rear engagement web 204 .

The rear grip web merges into the vertical web 218 of the connecting part 205 which is formed perpendicular to it. In the area of the parallel vertical surfaces 219 and 220, this has a depth 221 which is designed to be adapted to the selected joining and connecting method. At its lower end 221 , the connecting part 205 has the welding tab 225 formed with the material thickening 222 . The material thickening 222 extends on the one hand in the direction of the edge spar 58 and is further delimited by the horizontal lower surface 223 and the vertical surface 220 . The connecting part 205 has a depth 224 which is greater than the depth 196 of the connecting part 188 of the spring connecting element 170 . All corner transitions of the groove-connecting element 200 are rounded off in a way that is optimized for the material and stress. The distance between the vertical surface 220 of the vertical web 218 from the wedge surface 207 of the top wall part 202 of the groove-connecting element 200 and the distance between the vertical surface 191 of the vertical web 173 from the wedge surface 174 of the transition part 157 of the spring-connecting element 170 are selected so that in the assembled state, the gap 230 is formed between the two opposite vertical surfaces 220 and 191 ( FIG. 7).

In Fig. 7, the cross joint connection element 160 is shown with the cross joint connection element parts 155 and 156 in a mounting arrangement. To assemble the scaffold floor profile parts, these are inserted horizontally into one another with the cross joint connection element part 155 containing the spring connection element 170 and the cross joint connection element part 156 containing the groove connection element 200 . First, the spring part 180 is inserted into the groove 215 and then a horizontal displacement movement is carried out parallel to the scaffold floor transverse axis 169 until the wedge surface 207 of the top wall part 202 of the groove connection element 200 contacts the wedge surface 174 of the transition part 157 of the spring connection element 170 abuts. For this purpose, the depth 210 of the top wall part 202 is greater than the depth 185 of the horizontal web 172 . When inserted, the conical surface 182 of the spring part 180 of the spring connection element 170 touches the support surface 213 of the rear engaging web 204 of the groove connection element 200 . Because the maximum thickness 199 of the spring part 180 having the conical surface 182 is greater than the groove width 216 , the conical surface 182 of the spring part 180 presses on the supporting surface 213 of the rear engaging web 204 of the groove-connecting element 200 when inserted further. As a result, the upward-facing contact surface 175 of the horizontal web 172 of the spring-connecting element 170 is pressed against the downward-pointing contact surface 209 of the horizontal upper wall part 202 of the groove-connecting element 200 , so that in the assembled state a rattle-free connection between the two cross joint connection element parts 155 and 156 and consequently between the edge- bottom profile parts 48.1 , 48.2 and the bottom-center profile part 49 is made possible.

The structural design of the cross joint connection element parts 155 and 156 , in particular the formation of the tongue and groove connection in connection with the contact of the rear engaging web 204 on the tongue part 180, enables a tongue and groove connection secured against loosening due to stress. A welded connection is additionally provided, as can be seen in FIG. 7, in order to create a connection between the neighboring parts of the scaffolding floor that will permanently withstand the stresses on scaffolding floors. For this purpose, the welding flaps 190 and 225 formed with the material accumulations 189 and 222 are provided at the lower end of the vertical webs 173 and 218 of the spring-connecting element 170 and the groove-connecting element 200 . The welding groove 227 is provided for receiving the weld metal 226 shown in dotted lines in FIG. 7. In the assembled state, this is formed between the lower inclined surface 194 of the welding tab 190 and the vertical surface 220 of the vertical web 218 containing the welding tab 225 . To avoid an undesired flow of material when welding the relatively thin vertical webs 173 and 218 , the welding tabs 190 and 225 are formed with the material accumulations 189 and 222 .

FIG. 9 shows a further alternative design of the cross joint connection element parts 255 and 256 . These are designed with weld-free, screw-free and rivet-free behind-grip joining structures. In the exemplary embodiment, the cross-connection element parts 255 and 256 are also designed with a tongue and groove connection, with the tongue connection element 270 and the groove connection element 300 . The spring connection element 270 is designed in the same way as the spring element part 170 shown in FIG. 8.1 and described above with the transition part 257 , the diagonal web 271 and the horizontal web 272 formed with the spring part 280 . These partial elements are structurally identical to the spring connection element 170 described above.

The spring connection element 270 has the vertical web 273 . This is arranged on the horizontal web 272 in the same way as the vertical web 173 on the horizontal web 172 . The vertical web 273 is delimited by the vertical surface 292 facing the central spar 59 and by the opposite diagonal surface 291 . At its lower end 286 it merges into the horizontally extending hooking arm 294 . The latching hook 296 is formed in one piece at its free end 295 . This has the insertion slope 297 , which runs obliquely upwards and the vertical latching surface 298 adjoining it at an acute angle downwards. The transition from the vertical web 273 to the hooking arm 294 is designed with the generously dimensioned outer radius 288 and the likewise generously dimensioned inner radius 289 . The vertical web 273 has at its base 284 a wall thickness 285 which corresponds approximately to the wall thickness 276 of the horizontal web 272 . The vertical web 273 tapers - starting from its base 284 - continuously downwards to approximately half its height on the wall thickness 277 .

The groove connection element 300 has the top wall part 302 , the vertical web 303 , the rear gripping web 304 and the vertical web 318 . The top wall part 302 is configured identically to the groove connection element 200 described above. The vertical section 303 is limited by mutually parallel vertical surfaces 317 and 311 and goes to the extending at an angle of 90 ° in the direction of the wedge surface 274 and parallel to the top wall part 302 inter-engagement rib 304 in height of the support surface 313 on. The transition from the vertical surface 311 of the vertical web 303 to the lower outer surface 314 of the rear gripping web 304 , which extends at an angle of 90 ° thereto, is rounded off with the radius 312 . In the transition region to the vertical web 318, the rear gripping web 304 is also essentially the same as the rear gripping web 204 of the groove-connecting element 200 . The vertical web 318 is delimited by the two parallel vertical surfaces 319 and 320 . The vertical surface 320 continuously merges into the inclined surface 330 in the region of the free end 321 of the vertical web 318 , which intersects with the vertical surface 319 at the free end 321 of the vertical web 318 at the pointedly shaped snap edge 331 .

To assemble the scaffold floor profile parts, the edge-floor profile part 48 and the middle-floor profile part 49 with their cross joint connection element parts 256 and 255 are also joined together by horizontal transverse insertion and sliding movement. This is possible easily and inexpensively on roller conveyors, in that suitably designed pressure rollers are pressed on the one hand against the vertical surface 311 of the vertical web 303 of the groove-connecting element 300 and on the other hand against the vertical surface 292 of the vertical web 273 of the spring-connecting element 270 . In the present exemplary embodiment, the additional connection securing of the scaffolding floor profile parts is carried out by latching the latching hook 296 of the hooking arm 294 of the spring part 270 on the securing surface 332 of the vertical web 318 of the groove-connecting element 300 formed with the vertical surface. When the spring connection element 270 and the groove connection element 300 are joined together , the inclined surface 330 of the vertical web 318 touches the inclined surface 333 of the insertion bevel 297 of the latching hook 296 . In the course of the continued insertion, the inclined surface 333 slides on the inclined surface 330 , the hooking arm 294 elastically deflecting downward. Finally, the latching hook 296 engages on the securing surface of the vertical web 318 with simultaneous elastic return of the hooking arm 294 . This results in an inseparable, metal melt flow-free, hot-joining process-free, weld-free, screw-free and rivet-free formed under-grip connection for the permanent securing of the adjacent scaffold floor profile parts.

In addition to the securing measures described above, an adhesive connection can additionally be provided in the region of the two wedge surfaces 307 and 274 , in the region of the contact surfaces 309 and 275 , in the region of the cone surface 282 and the support surface 313 and in the surface regions assigned to the groove 315 .

Fig. 11.1 to 11.3 show how the entire tread 55 perforations 355.1, 355.2 with up or bulged bottom hole edges 378.1, 378.2 and is provided with rib-like roughness. On the one hand, these enable a non-slip surface and, on the other hand, the drainage of fluid media. Fig. 11-3 shows a left corner of the framework floor 45 with the hooks 46.1 in plan view. With the exception of the tread areas between the vertical spar walls 89 and 159 or 154.1 and 154.2 assigned to the edge spars 58.1 , 58.2 and the center spar 59 , the tread 55 has oval openings 355.1 and 355.2 which are arranged in longitudinal rows 351.1 , 351.2 . Within a longitudinal row 351.1 and 351.2 , the perforations 355.1 and 355.2 are each evenly spaced such that their longitudinal axes 356.1 and 356.1 are alternately offset from one another by the angles 357.1 and 357.2 of 90 ° C. The longitudinal axes 356.1 and 356.2 of the openings 355.1 and 355.2 each form an angle 358 of 45 ° C. with the scaffold floor transverse axis 169 ( FIG. 6.1). The perforations 355.1 and 355.2 are also arranged in longitudinal rows 351.1 and 351.2 in the tread 55 in such a way that they cut both the partial area 56 provided with roughness-forming longitudinal ribs 63 and the subsequent partial area 57 designed with a smooth surface. Furthermore, the openings 355.1 and 355.2 of mutually adjacent longitudinal rows 351.1 and 351.2 are each arranged in transverse rows 361.1 and 361.2 . The openings 355.1 and 355.2 provided in the transverse rows 361.1 and 361.2 are each offset from one another at an angle 362 of 90 ° C.

The hole edges 378.1 of the openings 355.1 are each bulged upwards and the hole edges 378.2 of the openings 355.2 are each bulged downwards (FIGS . 11.2 and 11.3). The first transverse row 361.1 adjacent to the cross-connection cap 54 has the perforations 355.1 with the hole edges 378.1 bulging upwards. These openings 355.1 are at a distance 364 from the thigh 66 of the cross-connection cap 54 which is smaller than the length 366 of the openings 355 and which here is approximately twice the width 367 of the openings 355 .

Due to the arrangement and design of the openings 355.1 and 355.2 described above, not only is sufficient slip resistance and the drainage of fluid media ensured, but it also means the least possible material damage to the running surface 55 . This prevents local deformation or other undesirable damage to the tread 55 in the case of local stress, for example with a shoe heel or with objects supported on the tread 55 at points.

The openings 355.1 and 355.2 each have the same oval hole design. They are each designed with the perforated edges 368.1 and 368.2 running parallel to the longitudinal axis 356.1 and 356.2 and are rounded at their ends 369.2 and 369.2 with the same radius 370.1 and 370.2 . The openings 355 have the length 366 and the width 367 , the ratio of length 366 to width 367 here being approximately 5: 1.

Due to the arrangement of the openings 355.1 and 355.2 described above, their perforated edges 368 , 378 - as shown in FIGS. 11.2 and 11.3 - are partially formed with the longitudinal ribs 63 . These are each at a distance 373 from one another in the undeformed hole edge region and run parallel there. They are formed on their upper sides with the partial cylinder surfaces 374 and have a height 64 , which here is approximately 25 to 30% of the distance 373 of the adjacent longitudinal ribs 63 . The longitudinal ribs 63 have a height 64 which here is approximately 45% of the wall thickness 81 , 82 of the upper walls 111 and 151 of the edge-bottom profile parts 48 and the bottom-center profile part 49 ( FIG. 7).

The upwardly curved hole edges 378.1 of the openings 355.1 and the downwardly curved hole edges 378.2 of the openings 355.2 have the bulging depth 379.1 and 379.2 . This corresponds approximately to the wall thickness 81 , 82 of the upper wall 111 of the edge-bottom profile parts 48 or the top wall 151 of the bottom-center profile part 49 containing the tread 55 .

An important part of the description is given below:
The scaffold floor 45 has at least one light metal extruded profile part oriented in its longitudinal direction. According to a preferred embodiment of the invention, end connection means connecting the floor profile parts are provided, which are formed with steel cross-bracing profiles. According to an alternative embodiment of the invention, the end connection means are connected to the base profile parts free of metal melt flow or free of hot joining processes. A further preferred embodiment is formed with transverse box-shaped longitudinal reinforcing bars, between which longitudinal seam connecting elements are arranged in the region of the upper part of the floor profile. According to a further alternative embodiment, the longitudinal reinforcement bars have an under-wall rear grip profile.
