WAYS OF CARRYING OUT THE INVENTION

A scaffolding support device 10, which is used as a scaffolding tower is formed, has scaffold posts 12 with in the longitudinal axis direction arranged in a predetermined grid R. Perforated disks 14, scaffold diagonals 18 and scaffold bars 20. The scaffold posts 12, scaffold diagonals 18 and scaffold bars 20 are components from the well-known Layher all-round scaffolding system. The components are interconnected about the proven wedge lock technology. For this purpose, the Ends of the framework diagonals 18 and the framework bars 20 Connection head units 22 integrally formed, one of the Have open slot 24 on the front side, so that the Terminal head units 22 on the perforated disk 14 can be postponed. The perforated disc 14 itself has recesses 16 distributed radially around the circumference. Furthermore, each connection head unit 22 has a vertical continuous recess 26 extending to slot 24, which in turn has a recess 16 in the perforated disk 14 can be brought to cover. In this state, a Wedge 28 in recess 26 and recess 16 struck so that a permanently reliable Connection of the components is guaranteed. This connection technology is known as such.

The scaffold support device 10 is a square support tower educated. In each corner area of the square are total four scaffolding stems 12 running parallel to each other arranged. The four scaffold posts 12 are via connection head devices 30 coupled to each other, whereby the Load capacity of the entire scaffold support device 10 enormous can be increased.

The connection head device 30 sees according to a first Embodiment 30.1 so that they have two connection head units 22 has that at an angle of 180 ° are arranged to each other, i.e. from both ends forth the slots 24 are present. With such a Connection head device 30.1 are two adjacent arranged scaffolding stems 12 coupled together by simply drive a total of two wedges 28 into the Recesses 26 and 16. A side view of the Details of such a coupling is enlarged in FIG. 3 shown.

Overall, there is a coupling in a corner area existing four scaffolding posts 12 via four connection head devices 30, as seen in FIG. 2 in a plan view arranged in the side edges of an imaginary square are, whose corner points in the axes of the four scaffold posts 12 lie.

1 takes place in the embodiment such coupling of four scaffolding posts 12 in the longitudinal axis direction the scaffolding stems 12 on every second perforated disc 14, i.e. the grid dimension of the couplings is 2R. A The payload can be increased if the Couplings described in the grid dimension R performed become.

There are 10 on the scaffolding support device per side wall according to the spacing of the scaffolding posts 12 in Corner area two scaffold bars 20 and scaffold diagonals 18 to the corresponding perforated disks 14 of the scaffolding posts 12 connected.

In each corner point there is a foot spindle 40 in the bottom area Spindle rod 44 and spindle nut 46 available, the Spindle rod 44 on one welded on the underside Support plate 68 with corresponding stiffening elements 69 is stored. The power transmission from the scaffolding posts 12 in the spindle rod 44 takes one in Fig. 4a to c Load centering unit 50.1 shown. This consists of a central tube 52 in which the spindle rod 44 is guided is and that is supported on the spindle nut 46. The outer circumference is offset by an angle 56 of 90 ° a total of four slim, high rectangular profiles as console units 54 welded to the free end area tubular receiving units 58 are in turn welded on, whose longitudinal axis each corresponds to the longitudinal axis of the associated one Scaffold 12 coincides. Are in the top Recording units 58 inserted sleeves 64 on which the corresponding end areas of the scaffold posts 12 plugged become.

Finally, there is one on each receiving unit 58 Perforated disc 14 welded with recesses 16 so that in Area of the load centering unit 50.1 an additional Coupling of the four incoming scaffolding posts 12 by means of Connection head devices 30.1 can be made or further scaffold bars 20 or scaffold diagonals 18 can be connected.

The detail of the connection of the load centering unit 50.1 the foot spindle 40 and the connection of the scaffold posts 12 shown schematically in Fig. 5.

In the upper head area of the scaffolding stems 12 is another Load centering unit 50.2 arranged with respect to the central tube 52, the console units 54 and the receiving units 58 essentially that already described Load centering unit 50.1 in the foot area corresponds. There are however, no perforated disks 14 are welded on, likewise none Push-in sleeves 64 are present on the load centering unit 50.2.

In the central tube 52, the spindle rod 44 is one Head spindle 42 guided, the head spindle 42 over the Spindle nut 46 is mounted on the central tube 52, the its load over the console units 54 and receiving units 58 to the four scaffolding posts 12. At the top The end region of the head spindle 42 is a U-shaped one that is open at the top Support shoe 48 articulated, the For example, one is not suitable shown yoke carrier to record.

The ones required for the lower load centering unit 50.1 Receptacles 64 can in the upper load centering unit 50.2 are omitted, since such sleeves 66 are already in inserted into the upper end region of each scaffold post 12 are.

The connection of the head spindle 42 via the load centering unit 50.2 to the four scaffolding posts 12 is in FIG. 7 shown schematically.

Different embodiments are shown in FIGS. 8 to 11 from connection head devices 30.1 to 30.4 shown.

The connection head device 30.1 is already on the occasion of Description of Figures 1 to 3 has been explained. at In this embodiment, the two connection head units 22 an angle 32 of 180 ° to each other.

In the embodiment of a connection head device 30.2 according to FIG. 9 are also two connection head units 22 present on a core unit 60, which, however, in one Angle 32 of 90 ° to one another to a core unit 60 are connected. The possibility of arranging a third connection head unit 22 is at an angle of 90 ° indicated by dashed lines in FIG. 9.

A particularly preferred embodiment of a connection head device 30.3 is shown in Fig. 10. in this connection there are a total of four connection head units 22 which seen in a plan view at an angle 32 of 90 ° circumferentially offset on a cube-shaped Core unit 60 are connected. Such a connection head device 30.3 can the four connection head devices 30.1 for the four available in the corner area Scaffolding posts 12 of the scaffolding support device 10 according to FIG. 2 replace, in the areas where the interior no further component between the four scaffolding posts 12 is available.

As already stated, the connection head units 22 via the slot 24 on existing on the scaffolding posts 12 Perforated disks 14 pushed on. These perforated disks are in the Figures 8, 9 and 10 indicated by dashed lines.

A connection head device is essential to the invention to look at, for example, a polygonal core unit has, on the outside connection head units are connected. The polygon can be a triangle, Rectangle, pentagon, hexagon or the like.

An embodiment with a hexagonal core unit 60 is shown in FIG Fig. 11 shown. There is one on each outside of the polygon Connection head unit 22 connected.

The embodiment according to FIG. 11 draws another one Special feature. At the center of the core unit 60 is one of Continuous recess 36 available at the top, whereby A hollow profile unit 38 on the top and bottom is connected, the inside diameter of which Corresponds to the inner diameter of the recess 36. So that serves the connection head device 30.4 on the one hand the coupling several scaffolding stems and on the other hand a central one Load introduction via a spindle. This connection is in Fig. 13 is shown schematically. The head spindle 42 gives the load on the hollow profile unit via its spindle nut 46 38 and thus to the connection head device 30.4 again their stress on that in Fig. 13 not closer passes the scaffolding shown. The same connection head device can also be used in the area of a foot spindle Load centering and coupling are available.

The core unit 60 with or without recess 36 can also be used as Profile element be formed.

A recess 36 can also, for example, in a square core unit 60 (for example according to FIG. 10) to be available.

With the scaffold support device shown, it is possible without any problems, using largely standardized Components to manufacture a scaffolding support device can take very high vertical loads and is suitable also to transfer horizontal loads. At the same time enables quick assembly and disassembly. By the use of foot spindles and head spindles is one Height adjustment to the respective conditions on site possible without any problems.
