The invention relates to a support tube for small structures, in particular to their frame structures, which tube is provided with at least one connecting profile releasably connected to it, the circumference of which has at least one tubular projecting strip and which rests on the outer circumference of the support tube.

By small structures is meant here, for example, open shelters, waiting halls, cabins, kiosks, stalls and the like.

Such small structures most often have frame structures and can be made with an arbitrary floor plan.

An important part of the frame frame structure is always the support pipes and their connection profiles to which walls or doors made of sheet metal, corrugated sheets, glass, wood or the like can optionally be attached or installed inside or outside the frame frame structure as required.

To date, in particular, the attachment of walls and doors to a frame structure or support pipes has proved to be relatively difficult, as such joints between walls and support pipes are subject to high requirements in terms of durability, strength and tightness, resulting in significant costs for the numerous joints required to make such joints. .

Screw and / or welding joints are used in small structures of the above-mentioned type or in their frame-frame structures. However, in the case of welded joints, it must be borne in mind that, when used, it is very difficult to replace damaged wall sections with new wall sections if this is sometimes necessary, which is why screw joints are preferred over welded joints in practice. Given that small structures are different in shape, i. they can be made triangular, quadrangular or polygonal, it is often the case that the two wall parts connected to the support tube do not always form an angle of 90 °, but that such an angle formed by the two wall parts can be below or above 90 °, as the case may be.

For example, DE-A-844 055 discloses a rod-shaped structural element, in particular for temporary wall structures, which element is in the form of a tube with diametrically opposed, perforated strips or profiles. Such structural elements can be used to a limited extent in small structures with a rectangular base, but they are not suitable for different shapes, for example for triangular or polygonal structures.

The invention can be mainly based on DE patent publication 2 305 612, which relates to a hollow light metal profile used for support and / or lattice points of a frame structure. However, this rod-shaped hollow profile has some disadvantages in terms of the connection possibilities of the connecting parts in small structures, as well as the appearance of the structure.

According to the publication, since the hollow profile is provided with longitudinally extending, inwardly widened grooves, the connection profiles can only be threaded into the profile at this end. The circumference of the rod-shaped profile does not have any fixed connection strip 3 68105 which is identical with this. This means e.g. the fact that in the assembly work of the structure all the connection strips, which in addition have to be threaded into the profile at its end, must be fastened separately, which of course slows down the assembly work.

It is now an object of the invention to provide a support tube for small structures, in particular for their frame structures, with which the disadvantages of the known solutions described above can be avoided. To achieve this, the invention is characterized by a combination of the following features: a) that there is also at least one outwardly pointing strip on the circumference of the support tube; b) that a plurality of axially extending recesses are provided on the outer circumference of the support tube, and c) that in addition the inner side of the connecting profile formed in the shape of a circle has a plurality of protrusions emanating from the base circle which engage the recesses of the support tube.

According to Figs. The connection profile 12 is provided with holes 16 and correspondingly threaded holes 18 in the support tube 10 so that the countersunk screws 14 can be passed through the holes 16 and screwed into the threaded holes 18 of the support tube 10. The connection profile 12 is further provided by an extrusion method known per se. a strip 20 which forms an integral part of the connection profile 12 and serves to attach the wall parts not shown in more detail here to the connection profile.

Preferably, the periphery of the support tube 10 made by the extrusion method is likewise provided with at least one radially outwardly facing strip 22 which forms a unit with the tube 10 and acts like a strip 20 of the connection profile 12 to attach wall portions to the tube substantially not shown here.

In the first embodiment shown in Figs.

The recesses and protrusions in each case arranged in the support tube 10 and the connection profile 12 are connected to each other in the installed state of the tube 10 and the connection profile 12, as a result of which the connection profile 12 is secured very well against the support tube 10 and thus cannot move circumferentially with the support tube 10.

The circumference of the support tube 10 preferably has an average distance of 15 ° from the corrugated recesses 26. This distance is similarly arranged for the wave-shaped protrusions 32 of the connection profile 12.

681 05 6

The connection profile 12 forms a circular arc in the 90 ° angular range. The radially outwardly facing strip 20 is arranged on the circumference of the connection profile 12 so that the radial line 36 passed through the end 34 of the circular arc forms an angle of 30 ° with the strip 20.

According to the second embodiment shown in Figures 3 and 4 of the connection profile 12 and the support tube 10, 15 15 recesses 48 extending into the angular region of the arcuate range, which substantially correspond to the outlines of the protrusions 42 arranged in the connection profile 12.

In the connection profile 12 shown in Fig. 3, the angle formed by the sides 50 and 52 of the toothed protrusions 42 is always greater than 90 ° with respect to the 90 ° circular arc of the profile 12 so that the connection profile 12 can be mounted unobstructed in its recesses 10 in the support tube 10

The angles α 'and α', respectively formed by the radial line 55 and the second side 50 or 52, represent angular diameters. Similarly, the size of the angle formed by the two sides, 54 and 56, as shown in Figure 4, is 90.

The required size of the angle formed by the sides 50 and 52 and 54 and 56 depends essentially on the angle range formed by the angle profile 12. When the angular range of the connection profile 12 is greater than 90 °, it is not possible to mount the connection profile 12 on the support tube 10 with the projections 12 of the connection profile 12 and the recesses 48 of the support tubes 10 in the structure 10. For example, see the direction of movement of the connection profile 12 with the support tube 10.

The relatively most used profiles 7 of the support tube 10 are shown in Figures 5-8. 6 81 0 5

The profiling shown in Fig. 5 corresponds to the profiling of the support tube 10 described in connection with Fig. 4 and therefore does not need to be explained in more detail here. The associated interface profile is shown in Figure 3.

According to Fig. 6, according to a third embodiment, the support tube 10 has trapezoidal recesses 64 starting from its outer circular circumference 62. The average distance between the individual recesses is 15 degrees of arc and thus corresponds to the distribution of the part of the circular circumference 24.

The angles α 'and α ", each formed by the radial line 66 and the other side 68 or 70, are angular diagonals which together form an angle of 90 °. A connecting profile not shown here is provided with a circular arc-shaped inner side of 15 °. at average distances, trapezoidal protrusions arranged in each case in the shape of the trapezoidal recesses 64 of the support tube.

The profiling shown in Fig. 7 corresponds to the profiling of the support tube 10 shown in connection with Fig. 1. It should also be mentioned here that the angle formed by both angles a 'and a' is 90 °.

According to Fig. 8, according to a fourth embodiment, the support tube 10 has triangular recesses 74 at a distance of 15 degrees from the outer circumference 72, the sides 76 and 78 of which together form an angle of 90 °. The angles af and a ", which are in each case formed by the radial line 80 and the other side 76 or 78, are also angular diameters. In the connection profile (not shown), triangular protrusions are arranged on the circular inner side at an average distance of 15 degrees, respectively in the form of triangular recesses 74 in the support tube 10.

8 68105

In order to form the most used angular positions shown in Figures 9-27, on the one hand the strip 22 of the support tube 10 and on the other hand one or more connection profiles 12 or resp. 22, a division into 24 parts was best arranged for the placement of recesses and protrusions in the support tube or its connection profile.

The minimum angle between the two strips is 30 °. Other angular positions and examples of the arrangement of the support tubes 10 can be seen in Figures 9-27.

Other possible angular positions are accordingly 45 °, 60 °, 75 °, 90 °, 105 °, 120 °, 135 °, 150 °, 165 ° and 180 °.

According to Fig. 28, a spacer 82 is provided in each case on the floor and ceiling of a small building, mostly made of concrete, not shown, for fixing the support pipe 10 to the floor and ceiling, or it is screwed to the floor and ceiling.

The cylindrically formed spacer body 82 has a first portion 84 having a diameter slightly smaller than the inner diameter of the support tube 10. Further, the spacer 82 has a second portion 86 provided with a larger diameter relative to the inner diameter of the support tube 10, so that this second portion 86 of the spacer 82 extends over the upper and lower edges of the support tube 10.

When the support tube 10 is placed on one of the spacers 82 arranged on the floor, the tube with the strips 22 and the connection profile 12 with the strips 20 are brought in the desired direction. The connection profile 12 is then fastened to the support tube 10 with screws 14, which can also be, for example, self-tapping, or with so-called pop rivets.

Screws that cannot be removed by unauthorized persons are used to secure the support tube 10 with the spacers 82 in a manner not shown here, because special socket wrenches must be used for this purpose.

When the frame structure, i.e. the zone profiles 88, the gold profiles 90 and the support pipes 10 with their connection profiles 12 are upright, the wall or window parts 92 can be screwed in a simple manner to the connection profile 12 or the support pipe 10 strips 20 and 22. remove.

The invention is not limited to the embodiments shown. Within the scope of the invention, it is possible, for example, to arrange several strips on the outer circumference of the support tube 10 and / or on the connection profile 12 belonging to this support tube, if so desired. The shape of the recesses and protrusions in the support tube or in the connection profile can also differ from the shapes shown in the exemplary embodiments. It should further be pointed out that the recesses and the protrusions can also always be arranged at a greater distance from each other on the outer circumference of the support tube 10 or on the inner side of the connection profile than shown in Figures 1-8.
