Summary of the invention

Starting from the current state of the art, the The present invention is based on the objective or technical problem consisting of specifying a scaffolding platform that, maintaining its economic production, increase the variability of Assembly and use of scaffolding systems, make it easy to mount, make possible a variable surface configuration of scaffolding platforms, also in case of already created scaffolding, and that offers possibilities to increase the load capacities of scaffolding and avoid bending deformations that occur under load

The scaffolding platform according to the invention it has the characteristics indicated in the claim independent 1. In the direct dependent claims or indirectly to independent claim 1 are indicated advantageous configurations and improvements to the platform scaffolding according to the invention.

Therefore, the scaffolding platform according to the invention is characterized in that it essentially presents a U-shaped cross section with two wings provided with recesses separated from each other, the recesses of each wing are arranged in a longitudinal direction on a single axis, and the Longitudinal dimensions of the recesses have values different alternately in the longitudinal direction.

The recesses offer the possibility of introduce profiled crossbars that allow the coupling of gateways arranged in an adjacent position. To the at the same time, at the recess they can also be connected, at least temporarily, other elements, whether they are scaffolding components, and be other materials or equipment necessary within the framework of the activity of an operator, through connection units.

You can make a connection without problems components of scaffolding or other scaffolding platforms with different longitudinal system dimensions. Preferably the recesses are arranged symmetrically modular with with respect to the longitudinal center of the wing.

To achieve compatibility with system dimensions of scaffolding components already known in the market, an advantageous configuration is characterized because the Modular dimension of the recesses is chosen, at least by areas, such that an integer multiple of the modular dimension is equal to one meter (1000 mm).

To ensure compatibility with respect to scaffolding system components based on a dimension of metric system and scaffolding system components based on the dimensions of Layher's Blitz scaffolding system or system Known and accredited Allround scaffolding, a variant of Especially advantageous embodiment is characterized because two recesses located symmetrically with respect to the center longitudinal of the wing are arranged with a modular dimension of adaptation chosen in such a way that the sum of the modular dimension of adaptation and an integer multiple of the modular dimension of other recesses result in a system dimension of the scaffolding system

An embodiment that has given results especially good in practice is characterized because the Modular dimension of the recesses is equal to 125 mm (millimeters) and the modular adaptation dimension is 197 mm (mm) However, modular dimensions can also have other values For example, some modular dimensions of Advantageous adaptation are equal to 197 mm + n * 250 mm, with n = 0, 1, 2, 3, ...

A preferred configuration is characterized because the recesses have a rounded interior contour, in particular a circular and / or hole-shaped inner contour oblong.

Alternatively, another configuration that gives good result is characterized because the recesses have a polygonal interior contour, in particular an interior contour square or rectangular

In order to further increase the stability in the connection or housing area of the recesses for connection units or connection profiles, a advantageous embodiment variant is characterized in that the area marginal peripheral of a recess presents a reinforcement of cross section configured for example in the form of a fold inward or outward or in the form of a convex bulge or Concave cross section.

As material for the scaffolding platform Steel, aluminum or plastic.

In addition, the variability is increased by possibility of introducing profiled crossbars in the recesses of the wings of the scaffolding platforms and of connect on these profiled cross-section bars vertical connection profiles - for example through tube couplings-, which in the same way can constitute a possibility of connection with the scaffolding floor (s) located by above or below. In these profiled connecting bars Vertical console units can be attached at any height. Through the described configuration of the modular system of the recesses of the wings of the scaffolding platform ensures the possibility to easily connect other gateways scaffolding platform according to the system in the units of console connected to the profiled connecting bars vertical.

Another great advantage of scaffolding platform according to the invention is that the recesses reduce the weight of the individual scaffolding platform, without this having negative consequences on static load capacity. Through this weight saving greatly increases the ease of assembly and disassembly.

Finally, the recesses located on the wings of scaffolding platforms offer a simple possibility to suspend devices that are used for vertical transport or for material supply (eg lifting pulley).

In addition, the recesses present in the wings of scaffolding platforms offer simple possibilities (for example using S-shaped connection devices) to hang or connect tools, material, paint buckets, garments of dressing or any other equipment whose placement on the platform of corresponding scaffolding is not advantageous, at least temporarily.

In addition, the recesses in the wing of the scaffolding platforms offer the possibility of having places  of suspension for grips that allow to hook or unhook faster scaffolding platforms.

Finally, the scaffolding platform according to the invention offers the possibility, in case of scaffolding platforms superimposed, to reduce the span of scaffolding platforms by using profiled connecting rods transverse fittings and vertical connection profile bars connected with these, especially when the profiled bars of vertical connection are supported directly on the ground or the soil, which is particularly advantageous in case of large loads, since this considerably reduces the bending deformations.

It is also possible to configure without problems rigid flexion angles within a scaffolding system simply connecting a profiled connecting rod in a profiled crossbar inserted into the recess or recesses of the scaffolding platform, and also connecting its other end to the scaffolding components present.

They can also meet without problems two or three scaffolding platforms coupled through the bars transverse connection profiles to form a surface of work, which can then be used as a work area, in particular as a scissor table, for example by means of a adequate substructure.

The forecast of recesses in the wings of the Scaffolding platform also offers the advantageous possibility of be able to take fall protection measures practically in any position, for example simply by hooking the belt of protection against falls in the corresponding recess present in virtually any position of the wing of the scaffolding platform.

In order to increase flexural stiffness and load capacity and to reduce bending deformation of individual scaffold gateways, it is also possible to connect lateral reinforcement brackets, for example support profiles, using profiled crossbars, which is can be carried out simply by means of coupling units of tubes, if the supports to be reinforced are configured in the form of tubes

Finally, the end zone laterally protruding from the profiled connecting bars introduced in The recesses of scaffolding platforms can be used easily for connection of railings or for fixing edge boards.

As already mentioned above, you can use recesses with the inner contour shapes more diverse. Through the possibility of mixing different forms of hole and hole modules you can optimally take advantage of the connection of other components through the change of many possibilities of introduction in the longitudinal direction of the wing of the scaffolding platform. With the scaffolding platform according to the invention platforms can be arranged in metric dimensions and for example in the dimensions of the known systems of Scaffolding of Layher "Blitz" and "Allround". At the same time, The scaffolding platform described can be used in different scaffolding systems, for example, depending on the configuration of the connection units, such as connection claw units for suspension in U profiles open upwards, for suspension in round tubes or for suspension in spikes.

Other embodiments and advantages of the invention follows from the characteristics indicated in the claims and of the specified embodiments more down. The characteristics indicated in the claims are they can combine with each other at will, provided they are not excluded in an obvious way.

Embodiments of the invention

In figure 1a it is represented schematically in perspective a 10.4 scaffolding platform that, according to figure 2, it presents a cross section essentially U-shaped with a step surface 12 with holes 13 at the top and wings 14 facing down and formed on the longitudinal lateral edges.

On the faces of the front ends corresponding front end plates 15 are formed facing down, in which two units of connection 16 presenting an L-shaped cross section with one arm facing down. These connection units 16 serve to suspend the 10.4 scaffolding platform for example of a horizontal bar of a scaffolding system presenting a section U-shaped cross section oriented upwards.

Each wing 14 has through recesses 20, 22 with a closed inner peripheral contour. In this context they are formed first recesses 20 that have an outline inner circular peripheral with the diameter L1 or H. Next to these second recesses 22 are formed that have the height H and length L2.

The recesses 20, 22 are arranged symmetrically with respect to the longitudinal center in a module predetermined in the longitudinal direction of the wing.

The first two recesses 20 arranged symmetrically with respect to the center they have a dimension Modular adaptation A. The first and second recesses 20, 22 which join them in the direction towards the front end face are arranged with the modular dimension R. In this context they are always arranged alternately a first recess circular 20 and then a second recess in the form of oblong hole 22, and so on.

The recesses shown 20, 22 are Examples of realization There may also be recesses that have a polygonal inner peripheral contour, for example in Shape of a square or a rectangle.

Figure 1b shows the area of the end of scaffolding platform 10.4, on whose front face 15 a connection unit 17 is attached which presents in each of its two ends a continuous recess 19 and that, consequently, It can be suspended from spikes present in the scaffolding system. Figure 1c shows the end zone of the scaffold table 10.4 with two connection units 18 fixed on the front face 15 that have a circle-shaped cross section contour partial and that, therefore, are suitable to suspend them from round profiles

As Figure 2 shows, the recesses 20, 22 They can be produced simply by punching. According to exemplary embodiment according to figure 2, the wing wall is extends straight to the recess 20, 22.

However, it is also possible to provide a cross section reinforcement in the peripheral area of each recess Figures 3a to 3c are represented as possible. embodiments of a cross section reinforcement of this type, which are preferably produced by forming in cold. According to figure 3a, the section reinforcement Transversal is done by stamping a convex bulge 42 in the wing wall directly in the peripheral marginal zone of the recess 20. In figure 3b a bulge has been stamped convex 44 in the marginal area of the recess, located at a determined distance from the recess 20, that is, from the area from convex bulge 44 to the edge of the recess there is a wall projection 46. In the exemplary embodiment shown in the Figure 3c, the cross-sectional reinforcement is that the wing wall has a fold 48 in the peripheral marginal zone of the recess, such that the fold 48 is slightly tilted in.

In figures 4a to 4e a side view of scaffolding platforms 10, 10.1, 10.2, 10.3, 10.4 that have different system lengths and that present in each case the same system of modular dimensions with the dimension Modular A for the first two interior recesses 20 and R for the other recesses 20, 22, being in this case the first and second recesses 20, 22 also present alternately in longitudinal direction. Scaffolding platforms 10, 10.1, 10.2, 10.3, 10.4 represented differ in their length from such so that, starting from the scaffolding platform 10 according to the figure 4e, each next scaffolding platform located above presents an increased length in a modular dimension of SR system preset

As Figure 4a shows, the module of the recesses 20, 22 is configured in sum so that there are present recesses 20, 22 separated whose distance corresponds to the system dimensions S1, S2, S3 for example of a system of scaffold.

In the embodiment shown, the Modular dimension A is equal to 197 mm (millimeters) and the dimension Modular R is equal to 125 mm (millimeters). Modular dimensions S1, S2 and S3 are equal to 1572, 2072 and 2572 mm (millimeters). The modular dimension SR is equal to 500 mm (millimeters).

By setting the recesses in the system of modular dimensions represented and the forecast of longitudinal holes you can get the most diverse system lengths for the connection of system components, which offers great advantages especially when it comes to variability of use of these scaffolding platforms within of a scaffolding system. This is mostly because through of the scaffolding platforms a coupling is made by additional components, which is described below. By consequently there is no problem to get the dimensions of Layher's Allround scaffolding system or the Laylit Blitz scaffolding, or also use scaffolding platforms whose system dimensions are based on a metric system.

In figures 5 to 8 it is described as a example the coupling of scaffolding platforms 10, 10.1 to 10.5 arranged in adjacent position. Figure 6 shows a view in platform surface of a scaffolding system. He normal scaffolding field features 24 vertical posts and bars horizontal 26 joining the vertical posts 24 (connections not shown) and in which the Scaffolding platforms 10 through their connection units 16. The scaffolding surface formed by the two scaffolding platforms 10.3 can be easily expanded with console surfaces Scaffolding To do this, in the corresponding places introduce profiled crossbars 30 in direction  transverse through the corresponding recesses 20, 22 and, when inserted, said bars protrude from the sides of the two scaffolding platforms 10.3. In the outstanding part of profiled cross-link bars 30 are introduced from outside two scaffolding platforms 10 (represented by the left up in figure 6) and two 10.2 scaffolding platforms (represented on the right below in figure 6), that is, the profiled crossbars 30 are strung in the corresponding recesses 20 or 22 of the scaffolding platforms 10 or 10.2. The cross-section profiled bars 30 they also have an outstanding part on both sides in which fixing units that can be connected detachably prevent an interstitium from forming between scaffolding platforms 10 or 10.2 crossed by the bars. Another effect of the bars transverse connection profiles 30 is that platforms present in the scaffolding system cooperate in the static load support, that is, if it is subjected to load only a 10.3 scaffolding platform, the adjacent platform helps to support the load, which leads to a reduction in bending deformation

As profiled crossbars 30, for example, round steel tubes with a diameter of 33.7 mm (millimeters), a common diameter in the field of steel profiles. At the same time, the recesses 20, 22 it has a height H that is slightly larger than the diameter of the cross-linked profile bars 30 introduced through from the same.

The fixing units 40 may be preferably configured in the form of coupling units of tubes, which are used in large quantities in the construction of scaffolding and that, in addition to setting scaffolding platforms in position adjacent at the same time also offer the possibility of connect other profiled scaffolding elements.

In figure 5 it is represented schematically a side view of the connection of platforms scaffolding 10 with a 10.3 scaffolding platform with different longitudinal displacements, and 10.3 scaffolding platforms, 10 arranged in an adjacent position are represented one below of another in Figure 5. The corresponding recesses 20, 22, to through which you can enter in each case a bar profiled cross connection, are schematically linked using the arrows P.

Figure 8 shows another example of how to Performing console surface configuration using the lateral introduction of scaffolding platforms 10.2, 10.3 in profiled cross-link bars 30 introduced in 10.4 scaffolding platforms previously present. It is also possible to make scaffold surface extensions that are extend at least by two scaffolding fields (represented at the bottom of figure 8).

Figure 7, similar to Figure 5, shows the arrangement of scaffolding platforms located in adjacent positions with different longitudinal displacements which extend over two scaffolding fields, and in this case scaffolding platforms arranged in adjacent position also They are represented with a vertical scroll. The recesses 20, 22 corresponding, through which you can enter in each case a profiled crossbar, are linked schematically by the arrows P.

In figure 9 a part of a scaffolding system, such as the Blitz scaffolding system from Layher, in which frame components with posts are used vertical 24 and horizontal bars 26. In total they are represented three floors of scaffolding platforms. Each floor of scaffolding platforms consists of two scaffolding platforms 10.4 suspended from horizontal bars 26. Through the recesses of wings 14 of scaffolding platforms 10.4 of the upper and middle scaffold platform floors are introduced in each case two profiled crossbars 30 approximately at the points corresponding to one third of the platform through the two 10.4 scaffolding platforms located in an adjacent position, said bars protruding slightly laterally forward. In this outstanding area, the bars 30 transverse connection profiles of the scaffolding floors upper and lower are connected in each case with a bar vertical connection profile 32 through units of coupling (not shown in detail in the figure). How show figure 9 by way of example, using these bars vertical connection profiles 32 a structure of support on which other scaffolding elements can be connected, as console units 38 in this case. The profiled bars Vertical connection 32 are standard scaffolding tubes and, due to the geometry of the modular dimension of the recesses of the 10.4 scaffolding platforms, are arranged in the direction vertical in the dimension of scaffolding system S2. This allows easily and smoothly suspend a scaffolding platform 10 from the two console units 38. A big advantage of this construction is that console units 38 can be connect at virtually any height (arrow h) between upper and middle scaffold platform floors.

On the floor of scaffolding platforms there are also two 10.4 scaffolding platforms suspended from the bars horizontal 26.

In the points corresponding to one third of the platform, through the recesses of the platforms of 10.4 scaffolding profiled connecting rods are introduced transverse 30 that protrude forward and constitute a cantilever armor. In this outstanding area they are introduced two other 10.4 scaffolding platforms, resulting in a console surface corresponding to the scaffold surface which is inside the scaffolding system. So that it does not form no gap between the scaffolding platforms introduced, in the remaining area of the protruding end of the bars transverse connection profiles 30 are mounted units of fixation not shown in more detail in figure 9.

A view is shown in figure 10 side of a part of a scaffolding system, in each of whose 10.4 scaffolding platforms, seen in a vertical line, is introduced a profiled cross-link bar 30 through of the corresponding recesses, at whose outstanding end a profiled vertical connection bar 32 is connected in each level of scaffolding platform, reaching said bar until the ground. Thus, the span of 10.4 scaffolding platforms corresponding is divided in approximately half, so higher load capacities and lower deformations are achieved by Flexion under load.

Figure 11 differs from the representation of figure 10 in which in this variant embodiment there are in total three profiled vertical connection bars 32 connected to bars cross-section profiles 30.

In figure 12 it is represented schematically the connection of a profiled connecting rod 34 configured as a slash, which is also connected to through profiled cross-link bars 30 that are already previously entered in the corresponding positions in the scaffolding platform 10.4.

Figure 13 shows the possibility of producing rigid bending frame angles by profiled bars of suitable connection 34 connected in each case to a bar cross-section profile and a vertical pole 24.

Figure 14 shows a perspective of a part of the configuration of a scaffold surface between two Lattice supports 50 in a first embodiment variant. Between the two lattice supports 50, at the height of the upper head 52 corresponding, four scaffolding platforms are arranged 10.4 adjacent that extend parallel to the upper head 52 and that are coupled to each other through two profiled bars of cross connection 30 arranged approximately at the points corresponding to one third of the platform. The ends of the profiled crossbars 30 are connected to the upper head 52 of the lattice holder 50 corresponding to through connection units 54 schematically represented. The connection units 54 may consist, for example, of units of tube coupling, provided that the upper head is configured as tube profile.

Figure 15 shows a schematic view in perspective of another embodiment variant for configuration of a scaffold surface between two lattice supports 60. The 10.4 scaffolding platforms, arranged at head height corresponding upper 62 between the two lattice supports 60 separated, extend perpendicularly with respect to the head upper 62 and are simply suspended, by means of their connection units, of the upper head 62 configured in shape U-profile open up. Approximately in the points corresponding to one third of the platform, through the recesses of the wings of the 10.4 scaffolding platforms are introduced parallel cross-linked profiled bars 30 to lattice supports 60, which join the scaffolding platforms 10.4 arranged in an adjacent position forming a common plate. With this construction, the loads exerted on a platform 10.4 scaffolding are not supported solely by this platform scaffolding, but is distributed between 10.4 scaffolding platforms adjacent.

Figures 16a and 16b show in a section schematic transverse the possibility of easily increasing the Loading capacity of a scaffolding platform 10.4. For it load profile supports are arranged parallel to the edge longitudinal scaffold platform 10.4, which may be configured as profiles in I 70 according to figure 16a or as tube profiles 72 according to figure 16b. For profiles 70, 72 cooperate statically in the support of loads, through the 20 recesses of the wings of the 10.4 scaffolding platform is introduced at least one profiled crossbar 30 whose corresponding end is connected to the profile in I 70 or with pipe profile 72. Connection units are used for this 74.1 and 74.2 that are adapted to the geometry of profile 70, 72 correspondent.

In figure 17 it is represented schematically a part of a scaffolding system in which there are also profiled vertical connection bars 32 connected to profiled cross-link bars 30, similar to those Examples of embodiment shown in Figures 10 and 11. Without However, in this case the profiled connecting rods 32 do not they reach the ground, but they dock three floors of platforms scaffolding arranged one over another, so that the load exerted on a floor of scaffolding platforms is distributed between three scaffolding platform floors. Unlike the representation shown in figure 10, two bars are also used here vertical connection profiles 32 separated from each other. The bars vertical connection profiles 32 are connected to the bars transverse connection profiles 30 both in the front as in the back of the scaffolding system.

Figure 18 schematically shows the configuration of a platform that in this embodiment is formed by five 10.4 scaffolding platforms arranged in position adjacent, being introduced in the recesses of the wings in total four profiled crossbars 30 in one relatively narrow modular dimension. In figure 18 they are not represented in detail the means to fix detachable cross-linked profile bars 30 introduced

Figure 19 schematically shows the configuration of a so-called scissor table, which presents as  work surface for example two 10.4 scaffolding platforms arranged in adjacent position. At the ends and at the points corresponding to one third of the platform are introduced in total four profiled cross-linked bars 30 across of the recesses of the 10.4 scaffolding platforms, so that the two adjacent 10.4 scaffolding platforms act as a board.

On the two profiled connecting bars transverse outer 30 a vertical bar 80 is connected to through pipe coupling units not shown anymore In detail, it rests on the ground. For stabilization of the scissor table are provided two diagonal bars 82 that in each case they form a rigid angle to bending along with the 10.4 scaffolding platform and 80 vertical bar. Bars diagonals 82 are connected by the top in each case with profiled cross-link bars 30 inserted at points corresponding to one third of the platform, and for the lower part with the lower area of the vertical bar 80.

Figure 20 schematically shows the simple connection of a railing construction 84, which consists  on vertical posts 86 and horizontal bars 88, with a 10.4 scaffolding platform with wing recesses, which is carried out simply by connecting the vertical posts 36 with the protruding ends of profiled connecting rods transverse 30 introduced in the recesses of the platform scaffolding 10.

The profiled crossbars entered can also be used as insurance against the lifting scaffolding platforms joining the profiles of fixed form with the ground through connected elements.

In figure 21 two are represented 10.5 steel scaffolding platforms arranged one behind the another, which in each case has a modular dimension of expanded AS adaptation and also presented in each case three recesses 20, 22 arranged in the modular dimension R in the points corresponding to one third of the platform.

In the embodiment shown, the modular dimension is equal to 1197 mm (millimeters) and the dimension Modular R is equal to 125 mm (millimeters). The modular dimension AS is can set according to the formula 197 mm + n * 250 mm, with n = 0, 1, 2, 3, ...

At the bottom a 10.4 scaffolding platform that is arranged displaced laterally with respect to the two 10.5 scaffolding platforms and which is coupled with these through profiled bars of cross connection not shown in more detail. The corresponding recesses 20, 22, through which you can enter in each case a profiled connecting bar transversal, they are linked schematically by the arrows P.

The forecast of only three recesses 20, 22 in the area of points corresponding to one third of the platform allows 10.5 scaffolding platforms to withstand relatively high loads, while maintaining the variable connection possibilities offered by the recesses
