At least part of the chambers formed in the hollow sections is provided with a slot (15, 18) open to the outside. Preferably, the hollow sections are cubes with an external circular cross section and having internal walls, which partly run radially, connecting to a central core (8).

Description

Partition beam for production of mobile buildings

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a crossbeam for the production of mobile buildings, in particular fair and exhibition stands, consisting of a plurality of parallel metal profiles which are connected transversely between them by a transverse grid structure.

BACKGROUND OF THE INVENTION

Crossbeams are used in the construction industry for the production of overvoltage or in mechanical engineering, for example for the production of stationary columns or arms of building cranes and the like. As a rule, they consist of steel profiles that are welded or riveted with a grid structure or other beams. Such crossbeams are not suitable, due to their weight, for the production of mobile buildings, in particular fair and exhibition stands, because their assembly and dismantling are too expensive.

For the production of such fair and exhibition stands, however, building systems are known in which octagonal stationary columns with longitudinal grooves are used in which transverse beams can be inserted quickly and easily, but also very stably using suitable clamping locks (Octanorm system

Octanorm Betriebs-Vertriebs-GmbH (Bauelemente Filderstadt). Such systems are suitable up to a certain carrier length. For overvoltage of mobile, quickly assembled and demountable buildings, for larger self-supporting ceiling ¹ *. ¹ 'construction is also possible, such systems without change-use. For this purpose, crossbar systems are provided using connecting nodes (EP 0 393 090 B1) into which the ends of the bars provided with the foot can be hung.

However, since the use of crossbeams is also of interest for fair and exhibition stands for bridging larger bearing lengths or as a decorative element, the present invention aims to provide a crossbeam at the beginning of the aforementioned type that can be used as a supplement to existing

-2-rupture building systems and is suitable as a possibility of special aesthetic effects.

SUMMARY OF THE INVENTION

The solution of this problem is a cross beam at the beginning of the mentioned type, in which three hollow profiles are connected to a beam with the cross-section of an equilateral triangle, in which it has a hollow profile at the top of the triangle symmetrically and the other two hollow profiles mirrored symmetrically to the plane hollow chambers and at least a portion of the hollow chambers of all hollow sections have an outwardly open notch on its outside.

With this construction, the new crossbeam can be provided with clamping locks in the hollow chamber slots for connecting known components. However, it is also possible to use these notches to install additional parts, for example lighting installations or to slide the outer edges of the decorative panels, so that the crossbar becomes an aesthetic building element.

In a further embodiment of the invention, all the hollow profiles are designed as tubes with an outer circular cross-section which is connected to a concentrically positioned circular core of the tube by means of a plurality of inner walls directed radially to the workpiece. This construction results in stable hollow profiles which are, however, nice in shape and can be made, for example, of light metals such as aluminum. In this case, the circular core of the tube offers the possibility of making connections or, as mentioned below, the insertion of termination plates at the ends of the hollow profiles.

In a further embodiment of the invention, each sub-profile may have three chambers with outwardly open cuts, two notches each facing one notch on the side hollow profile, while the third notch is always positioned in the chamber directed out of the cross-section of the triangle. This construction allows the decorative panels to be slid into the chambers with the slots facing each other in the above-mentioned manner, the chambers corresponding to these slots having to be sized sufficiently large to guarantee the introduction of the edges of the panels.

The outwardly facing chambers allow, as already indicated, the attachment of additional columns or beams by means of known clamping means

-3zámkov. The notches and chambers can be adapted for this purpose by fastening notches of known fair building systems.

In a further embodiment of the invention, the notches which are not required are closed by decorative profile strips.

In a further embodiment of the invention, triangular plates are used for connecting the end ends of the hollow profiles, which can be screwed, for example, to the circular core of the tube.

These triangular plates may in a further embodiment of the invention be provided with a coupling for the connection of a further crossbeam or for the connection of stationary columns, the coupling consisting in one of the first embodiments of two bolt pins guided by reinforced ribs. suspension slots.

These column-type connection heads can be mounted, for example, on the previously mentioned stationary columns, and have recesses for insertion of the coupling hinge heads. In this way, the crossbeams according to the invention can be arranged very simply transversely to the known stationary column or can be connected in other ways to known systems.

In a further embodiment of the invention, however, the couplings may also consist of holes for insertion of plug pins which are provided on the connection heads. In this way it is also possible to use the crossbeams according to the invention separately as stationary columns and to combine them by means of their triangular plates with crossbeams or with other sections of the profile.

EXAMPLES OF EMBODIMENTS OF THE INVENTION

1 to 3, a crossbeam according to the invention is shown, which is made up of three hollow profiles 1, 2 and 3, which can be made, for example, as an extruded aluminum profile. The three hollow sections 1, 2 and 3 are arranged parallel to each other, as shown in the cross-section in Figure 3, and connected to a single beam with a cross-section of an isosceles triangle by means of a lattice grid structure 4 positioned therebetween. The grid structure 4 is welded. In the exemplary embodiment it consists essentially of a triangular structure disposed transversely to the longitudinal axes of the hollow profiles I to 3.

In Figure 3, it can be seen that the two hollow sections 2 and 3 are formed identically, but mirror-symmetrical to a plane 5 that extends through the center between the two equally long arms 6 of the triangular cross-section and the junction point of the two arms 6. a hollow profile 1 which is formed but different from the hollow profiles 2 and 3, the axes of which always lie at the contact point of the arm 6 and the base line 7 of the triangle.

The hollow profile 1 has an outer wall with a circular cross-section and concentrically to this outer wall a circular core of the tube 8 from which four dividing walls forming the hollow chambers 9, 10, ti and 12 are led out and from these are further parallel dividing walls extending parallel to the arms. The two compartments 13 and 14 are all arranged symmetrically to the central plane 5. The compartments 13 and 14 each have an open slot 15 open to the profile 3 or 2, and the slot 15 of the chamber 13 in the illustrated embodiment is closed by means of The edge of the decorative plate 17 is inserted into the slot 15 of the chamber 14. The chamber 12 has an outwardly open slot 18 whose longitudinal axis coincides with the central plane 5.

The hollow sections 2 and 3 likewise have a circular core of tube 8, from which five dividing walls extend to the outer circular wall of the tube, which form the five hollow chambers 19, 20, 21, 22 and 23. Of these chambers, the chambers 20, 21 and 23 again externally open cuts 15, wherein in the cut of the chamber 23, in each case analogous to the chambers 13 and 14, the profile strip 16 or the edge of the decorative plate 17 is likewise arranged so that they are directed towards each other. These can optionally be closed using profile strips 16, as shown on the left

6, or a decorative plate can be inserted into this notch as shown on the right side of Figure 3. The other notches 15 of the chambers 20 are open to the outside. Their longitudinal axis is always symmetrical to the central plane 5 in a plane parallel to the plane 5.

Figure 1 shows that the front ends of the three hollow sections 1 to 3 can be covered by triangular plates 24, which can be fixed, for example, by using screws (not shown) to the circular core of the tube 8 of the sections 1 to 3. in particular in Figure 5, by providing the decorative panels 17 on triangular sides, they form a closed structured element on all sides, which can serve in particular as an interesting sight for the eyes of fair and exhibition buildings.

Figure 2 shows that the triangular plates 24 are screwed in the form of two bolts 27 guided in the corresponding rib braces 26. The free ends of the bolts 27 are provided with hinged heads 31 of larger diameter which can be hung from above in the clamping groove 28 of the cylindrical connection head 29, in that the octagonal cross-section of the connection head 29 is interrupted by two orbiting ring grooves 30 into which the hinge heads 31 are inserted radially and then axially fitted behind the grooves 28. By means of two wing screws 32 a coupling 25 is fixed to the triangular plate 24 and to the suspended crossbeam.

Figures 4 and 5 show initially two crossbeams according to the invention in the embodiment according to figure 1 with front mounted triangular plates 24, wherein in the embodiment of figure 4 it is hinged by means of not shown clamping locks in one of the chambers J3 or 14 (figure 3) 33, which can again be used, as schematically shown, for a displaceable arrangement of a reflector 34. FIG. 5 shows, on the other hand, the possibility of fastening a crosspiece frontally closed by a triangular plate 24 by a hollow profile 1 not shown in a manner not shown; so that it can be used as a kind of structured element, and as shown in figure 5, it can also be equipped with integrated luminaires 35 in the decorative panel facing downwards.

Figures 6 to 8 relate first to the fastening method of Figure 2. Figure 7 shows a connection head 29 by means of which, as explained in Figure 2, two crossbeams according to the invention are connected transversely by means of a coupling 25 and triangular plates 24. Here, the connection head 29 is slid by means of the lower plug-in pin 36 shown in FIG. 2 into the hole 37 of the triangular plate 24 shown in FIG. 6, which serves here as the upper front end of the beam according to the invention. The three beams according to the invention form a spatial corner in the manner shown in Figure 7 (or 8). Of course, it would be possible to attach additional crossbeams to the connection head 29.

However, Figure 2 also shows that the coupling head 29 has, on its side facing away from the plug-in pin 36, an annular flange 39 having a central opening 38 into which the plug-in pin 40, which is positioned protruding from FIG. In this way, as shown in Figure 7, it is possible to extend the crosspiece serving as a stationary column axially upwards.

However, as shown in FIG. 8, it is possible to associate the previously mentioned plug-in pin 40 with the connection head 29 and to use the known profile column 41 with an octagonal cross-section and groove 28 of the connection head 29. In this case exhibition buildings, as sold by the applicant, with beams according to the present invention.

Of course, it is also possible, as already mentioned with reference to FIG. 3, to utilize a slot 18 of the chamber 1 of the profile 1 and a slot 15 of the two chambers 20 of the profiles 2 and 3 to combine the commercially available building elements.

Figures 9 and 10 show two examples of the use of new girders in connection with other parts of fair construction systems already on the market. In the exhibition stand according to FIG. 9, several crossbeams according to the invention having the reference numeral 42 are used. Three of these crossbars 42 are located on stationary columns 44 of the conventional type, which have an additional head lining 29 . On this

The couplers 25 are hinged to the connection head and, by means of them and the triangular plates 24, the crossbeams 42. These crossbeams and columns 44 are supplemented with commercially available stationary columns 41 and corresponding wall plates 45.

Figure 10 shows that, for example, with the help of three crossbeams 42, it is possible to assemble an arched ceiling structure by inserting corresponding and commercially available arched parts 43 into the open cuts of the chambers 20 (Figure 3) of the hollow sections 3 and 2 respectively. thus increasing the possibilities of using existing building parts for fair and exhibition buildings. They thus complement such fairing building systems, but can also be used without such parts, for example in the manner illustrated in Figure 7, as lightweight and fast but stable modular fairing building components.

Fig. 11 shows first a connection head 29 which, as will be explained further from Figs. 12 and 13, consists of a hollow hollow profile having axial slits 50 (or grooves 28 according to Fig. 2) on the outer periphery which open into equally axial chambers 51. These hollow chambers 51 are formed such that hinge heads 31 of bolt pins 27 can be inserted therein. It would of course also be possible to insert instead of triangular plates 24 with couplings 25 of other hinge heads 31 of other beams, for example beams in which bolts 27 They are aligned with two profile tubes parallel to one another, which are connected to each other by means of a plane beam. In this way, it would then be possible to connect flat bar beams.

Figure 11, in particular Figure 12 clearly shows that the column pieces of the connecting head tubes 29 are interrupted by two spaced apart ones. Also, the circular grooves 30, the axial dimension of which is sufficiently large to introduce the hinge heads 31 in a radial direction on the pipe axis of the connection head 29 and then to move axially down into the chambers 51. Figures 11 and 12 also show, however, that the connection head tube is closed up and down by one circular flange 39, which is fixed by means of screws 53 immediately at the front end of the tube. The screws 53 pass through the holes 54 of the circular flange 39 and can be inserted into the inner grooves 55 of the tube and screwed there. In the same way, it is possible to mount the lower circular flange 39, on which the hollow cylindrical connection piece 36 with the front end can be screwed in the same way.

9, the screws 53 can be inserted into the corresponding holes 54 '.

As shown in particular in Figure 13, the other grooves 57 are parallel to the hinge grooves 50 and radially from the inside of these on the inside of the chambers 51, which can be used to introduce commercially available clamping locks of known building systems by means of which The connection head 29 is then universally applicable.

11 and 12, it can finally be recognized that the guide grooves 30 can be inserted into the suspension grooves 50 and the chambers 51 by means of a groove 30 which abut the lower circular flange 39 and thus serve to adjust the height of the hinged hinge heads 31. Thus, the height adjustment of, for example, the girders according to FIG. 2 on the connection head 29 can be easily changed.
