Abstract

Exhibition stands are constructed using a lattice beam comprising several parallel hollow metal sections (1, 2, 3) which are held together by lattice structures. The hollow sections are assembled to form a beam with an isosceles triangular cross-section in which the hollow section (1) at the apex is symmetrical and the two other hollow sections (2,3) are mirror-symmetrical to the plane (5Ü running between the sides of equal length of the triangle. 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

Connecting head for lattice beams for mobile construction production.

The present invention relates to a head of lattice beam connection for component production mobile phones, particularly at trade fair and exhibition stands, which It consists of a tube segment with axially running grooves distributed on the periphery to engage tensioning elements of crossbars

In construction, lattice beams are used for the production of dust jackets or crane davit Construction or similar. Said lattice beams consist of general steel profiles that are welded or riveted with the lattice structure and with additional beams. These beams of Lattice are suitable because of its weight, but, because of this reason, they are not for the production of mobile constructions, in particular stands of fairs and exhibitions, because its assembly and Dismantling are too laborious.

However, for the production of such positions fairs and exhibitions are also known systems of construction in which octagonal support columns are used with longitudinally extending grooves, in which, with with the help of suitable tensioners, cross members can be inserted very easy and fast, but also very stable (Octanorm System of Octanorm Vertriebs-GmbH für Bauelemente de Filderstadt). Such systems are suitable for such wingspan In general, such systems are not suitable without further measures for the dust jacket of movable movable constructions and Quickly removable even for large roof constructions in cantilever In this case, framework systems are planned using junction nodes (EP 0 393 090 B1) where they can be attached bar ends provided with thickening.

However, since the use of beams latticework is also interesting for the construction of fairs and exhibitions to bypass larger openings or also as decorative element, although here it is necessary, a possibility simple to apply to the junction points, the present invention it is based on the problem of configuring a connection head of the type quoted at the beginning so that it can be used as complement of existing fairs construction systems and be suitable to make possible special aesthetic effects.

To solve this problem, it is foreseen in a connection head of the type mentioned above characterizing features of claim 1.

Due to this configuration, it is possible to simple way to arrange lattice beams transversely to known support columns that are provided with the head of Connection.

Thus, they can be arranged in lattice beams, for example, triangular plates with coupling means for connection to the connection head. The means of coupling can consist, in a first configuration, of two guided threaded bolts with reinforcing ribs, whose ends free have hook heads for the grooves of the connecting heads The connecting heads can be seated, by example, on the known support columns mentioned above. He Hitching process is done very easily by the provision of annular grooves, since no routing is necessary front of the hitch heads in the slots that run axially Therefore, lattice beams can be provided with a very simple way transversely to known support columns or they can be coupled in another way with known systems.

Other advantageous features of the new connection head result from the claims subordinates

In figures 1 to 3, a beam of lattice that consists of three hollow profiles 1, 2 and 3 that, for example, they may have been manufactured as extruded profiles of aluminum. These three hollow profiles 1, 2 and 3 are oriented in parallel to each other and, as the section shows cross section of figure 3, are assembled through lattice structures 4 formed as a framework, which run between them to form towards a beam with a cross section of an isosceles triangle. Lattice structure 4 is welded. In the exemplary embodiment, said structure consists of substantially of triangular structures placed obliquely with respect to the longitudinal axes of the profiles gaps 1 to 3.

Figure 3 shows that the two profiles gaps 2 and 3 are formed identically, but are placed with specular symmetry with respect to a plane 5 that extends in the center of the two sides 6 of equal length of the triangular cross section and through the point of intersection of these two sides 6. In this vertex of the triangle is arranged the hollow profile 1 which, however, is shaped so different from the hollow profiles 2 and 3, which are located with their axes respectively at the intersection point of sides 6 with the baseline 7 of the triangle.

The hollow profile 1 has an outer wall with circular cross section and a circular tube core 8 concentric to this outer wall, from which they extend four partitions for the formation of four hollow chambers 9, 10, 11 and 12 and from the partitions that extend parallel to the sides of the triangle, additional partitions still extend to the formation of two additional chambers 13 and 14. All partitions are arranged in this case symmetrically with respect to the plane medium 5. Chambers 13 and 14 are provided with a groove 15 open outwards, specifically to the respective profiles 3 and 2, the slit 15 of the chamber 13 being closed, in the example of embodiment represented by a profiled strip 16 and being lodged in the groove 15 of the chamber 14 a edge of a plate decoration 17. Chamber 12 has a slit 18 open towards outside, whose longitudinal axis coincides with the middle plane 5.

Hollow profiles 2 and 3 also have a circular tube core 8 from which five partitions extend to the outer wall of the annular tube, which form five chambers gaps 19, 20, 21, 22 and 23. Of these cameras, cameras 20, 21 and 23 are again provided with open slits 15 towards outside, being housed in the slit of chamber 23, analogously to the configuration of cameras 13 and 14, a respective profiled slat 16 or a respective edge of the plate decoration 17. The slits of the chambers 21 are arranged also so that they are oriented towards each other. Optionally, the slits can be closed with slats profiles 16, as indicated in the left half of figure 3, or a plate of decoration 17, analogously to what is shown on the right side of the Figure 3. The other grooves 15 of the chambers 20 open towards outside. Its longitudinal axes are symmetrically arranged with with respect to the middle plane 5 in a respective plane that runs parallel to the plane 5.

Figure 1 shows that the front ends of the three hollow profiles 1 to 3 by means of triangular plates 24 that can be fixed to the tube core circular 8 of profiles 1 to 3 using, for example, screws Not shown in detail. The plates 24 thus close the surfaces front of the lattice beam, which, as can be seen in particular in figure 5, it can be shaped as an element structural enclosure on all sides through the provision of decoration plates 17 on the sides of the triangle, whose element It can serve as special captamiradas especially in the construction of fairs and exhibitions.

Figure 2 shows that on the plates triangular 24 is screwed coupling means 25 into shape of two 27 threaded bolts guided in the corresponding reinforcement ribs 26. Free ends of threaded bolts 27 are provided with coupling heads 31 of larger diameter which can be hooked according to figure 2 from above in the clamping slots 28 of a connection head 29 in the form of tube because the octagonal cross section itself of the connection head 29 is interrupted by two annular grooves peripherals 30 in which the heads of radically are introduced hook 31 and then placed axially behind the slots 28. Two thumb screws 32 that can be tightened to hand, then take care of the fixing of the coupling means 25 with triangular plate 24 and the hanging lattice beam of the same.

Figures 4 and 5 show first two Lattice beams in one embodiment according to Figure 1 with triangular plates 24 placed on the front side, being engaging an electrical installation profile 33, in the example of embodiment of figure 4, in one of the chambers 13 or 14 (figure 3) through tensioners not shown in detail, whose profile, as schematically represented, can be used to your time for the movable arrangement of a light projector 34. By on the contrary, figure 5 shows the possibility of fixing the beam of closed lattice on the front side on triangular plate 24 with the hollow profile 1 upwards in a manner not illustrated in detail and close it completely out with the respective plates of decoration 17, so that said beam can be used as a kind of structural element and, as shown in figure 5, can also be equipped with integrated light sources 35 on the plate decoration directed down.

Figures 6 to 8 are first connected to the type of fixing according to figure 2. Figure 7 shows the connecting head 29, in which they are transversely mounted, in the manner explained with the help of figure 2, two beams of lattice through coupling means 25 and triangular plates 24. In this case, this connection head 29 is now inserted with its lower plug pin 36, visible in figure 2, into a housing opening 37 visible in figure 6 of a triangular plate 24 which serves here as the upper front closure of a lattice beam that is used as a support column. Three of the lattice beams according to the invention thus form, according to Figure 7 (or 8), a corner of a room. Naturally, it would still be possible to connect additional crossbars to the connecting head
29.

However, Figure 2 also shows that the connecting head 29 on its side away from the plug pin 36 it is provided with an annular flange 39 which has an opening central 38 where you can now enter and set again a plug-in pin 40, which is arranged in a triangular plate 24 according to figure 6 protruding from the front side. Thus, as shown in figure 7, it is possible to extend axially up the lattice beam that serves as a support column.

However, as Figure 8 also shows, it is possible to associate the plug-in pin 40 already mentioned before connection head 29 and place a known profile column 41 with octagonal cross section and with grooves in the manner of slots 28 of the connecting head 29. In this case, it is possible to combine with lattice beams one of the known systems for fair construction and exhibitions, such as the one sold by the applicant.

Of course, as already indicated with the help of Figure 3, it is also possible to use the slit 18 of the chamber 12 of profile 1 and grooves 15 of the two chambers 20 of profiles 2 and 3 to combine common components in the market with lattice beams using tensors.

Figures 9 and 10 show two examples of use of lattice beams in relation to other parts of the fair building system, such as those They are already in the market. At the exhibition stand according to the figure 9 several lattice beams are used here that are you now have the reference symbol 42. Three of these beams lattice 42 are mounted here on support columns 44 of type usual in the market, which are provided above a head of connection 29 - additionally coated in the exemplary embodiment. In this connection head the means of coupling 25 and, through these and triangular plates 24, lattice beams 42. These lattice beams and columns 44 are complement forming the position represented by means of Support columns 41 usual in the market and the corresponding ones wall plates 45.

Figure 10 shows that, for example, with help three lattice beams 42 can produce constructions of vault roof when arched parts are arranged corresponding 43, which are already on the market, in the open slits of chambers 20 (figure 3) of profiles gaps 3 and 2.

Figure 11 shows a connection head 29 which, as will also be explained with the help of figures 12 and 13, It consists of a hollow tube-shaped profile that is provided, in its outer periphery of slits 50 that run axially (or slots 28 according to figure 2), which lead to chambers 51 which also run axially. These hollow chambers 51 are configured so that they can accommodate the heads of hook 31 of the threaded bolts 27. Naturally, it would be possible also accommodate, instead of triangular plates 24 with the coupling means 25, other coupling heads 31 of others beams, for example beams in which the threaded bolts 27 are aligned with two profiled tubes that run parallel to each other other and that are linked together by means of a flat lattice. From this way, it would be possible then the connection of the beams of flat lattice.

Figure 11, but in particular Figure 12, clearly show that the column segment as a column of connection head 29 is interrupted with two annular grooves 30 running at a distance from each other, whose axial dimension is large enough to insert the coupling heads 31 into  radial direction to the axis of the tube segment of the head of connection 29 and then be able to move them down axially entering the chambers 51. However, figures 11 and  12 also show that the tube segment of the head of connection is closed up and down by a respective flange annular 39 which is applied directly to the front end of the tube segment with screws 53. Screws 53 they then pass through recesses 54 of the annular flange 39 and can fit into inner grooves 55 of the segment of tube and screw there. In the same way you can fix the flange lower ring 39, to which it can also be screwed even from the likewise a hollow cylindrical connection piece 36 with a front closure plate 56, being able to penetrate here also the screws 53 through the corresponding recesses 54 '.

As can be deduced particularly from the Figure 13, parallel to the engagement grooves 50 and radially inside of them they are provided on the inner side of the cameras 51 additional slots 57 that can be used to be able to introduce known commercial construction tensioners, to through which can be mounted again -usual crossbars also in the market- in the head tube segment of connection 29. Therefore, connection head 29 is universally usable.

Finally, figures 11 and 12 allow us to appreciate still that in hitch slots 50 and in chambers 51, it they can insert a groove studs 58 from the annular grooves 30, which rest on the lower ring flange 39 and, of this way, they can serve to adjust the heads of height hitch hooked 31. Therefore, changing the groove blocks it is also possible to easily vary the height adjustment, for example, of the lattice beams according to figure 2 in the head connection 29.
