Description

The invention relates to a connection head for a system for creating structures and a system for creating structures.

Known connection heads and systems for constructing structures are used, for example, for constructing double-storey stands. On the one hand, such two-storey trade fair stands must be quick and easy to assemble and, on the other hand, they must be reliably loadable. Known connection heads are marketed by the applicant under the name DFS 250 and have a hollow profile, extending from the starting on four sides connecting flanges off. The connecting flanges are intended for use with double T-beams, which are constructed as hollow profiles and whose lower boundary of the central web is milled in the region of the front side. As a result, a downwardly open pocket is formed in the region of the end of the carrier through the central web. To mount the carrier on the connection head, this is pushed from above onto the connecting flange, until the upper end bar abuts the upper end of the connecting flange. The connecting flange is then partially received in the pocket on the front side of the double-T-beam. In this position, the double T-beam is secured to the connection flange by means of screws.

From the Belgian patent BE 1006773 A5 is a connection head for a system for creating structures known, wherein the connection head has a tubular base body and is pushed over a likewise tubular support. The connection head has an upper end and a lower end, wherein a central longitudinal axis of the connection flange extends between the upper and lower end, and the connection head has two or three connecting flanges between the upper and lower end, each with a contact surface for applying a carrier. The connecting flanges and the abutment surfaces are laterally offset with respect to a radial plane to the central longitudinal axis and the abutment surfaces are arranged parallel with respect to the radial plane. The contact surfaces of the connection flanges are laterally offset by half the width of the connection end of a support.

This patent discloses the features of the preamble of claim 1 and claim 2.

In the French patent application FR 2 145 466 14, a connection head is shown, which has two connecting flanges arranged at right angles to one another between a base plate and a cover plate. In the region of the central longitudinal axis of the connection head, a slot is provided between the connection flanges in order to be able to pass through sections of a carrier.

From the German patent application DE 33 03 190 A1 a connection head for a system for creating structures with an upper and a lower end is known, wherein a central longitudinal axis of the connecting flange extends between the upper and lower end and wherein between the upper and lower end four connecting flanges each having a contact surface for applying a carrier are provided. The connection head is tubular and can be pushed onto a rod-shaped extension of a carrier. Carriers are then pushed onto the connection flanges, which then enclose the connection flange on both sides. This disclosure discloses the features of the preamble of claim 5.

With the invention, a connection head and a system for constructing structures are provided, in which a simple assembly and manufacture are possible.

According to the invention for this purpose, a connection head for a system for creating structures with an upper end and a lower end is provided, wherein a central longitudinal axis of the connecting flange between the upper and lower end, and at least one arranged between the upper and lower end flange with a contact surface for applying a Support in which the connection flange and bearing surface are laterally offset with respect to a radial plane to the central longitudinal axis, wherein the abutment surface is arranged parallel with respect to the radial plane in which the contact surface of the connection flange laterally offset by half the width of the connection end of a carrier is, in which a total of four connecting flanges are provided, the contact surfaces are arranged offset by 90 ° to each other and each offset laterally with respect to a central longitudinal axis to the plane and having a bottom plate and a cover plate, the parallel z Are arranged one above the other and between which the four connecting flanges are arranged.

Such a design of the connection head makes it possible to push a carrier laterally against the contact surface and still be able to arrange it centrally to the connection flange. The lateral pushing of the Support on the contact surface allows a much simpler installation of the carrier, since they can be introduced at the height in which they are ultimately to be mounted in the structure. For example, carriers can also be used below an already lying ceiling. The upper end is formed, for example, by a lid surface of a lid plate and the lower end by the bottom surface of a bottom plate.

By displacing the contact surface of the connecting flange, the center plane of the carrier is then exactly on a radial plane to the central longitudinal axis.

By providing four connection flanges, up to four supports can be arranged on the connection flange. Even when arranging four carriers, it is still possible to pivot the carrier laterally against the contact surfaces of the connecting flanges.

The invention also relates to a system for constructing structures with at least one connection head according to claim 2.

The provision of an end-side receiving chamber on the carrier allows the insertion of the coupling part and the overall very easy training of the wearer. For example, the carrier can be formed as an aluminum hollow profile. The coupling part itself, yes the considerable In contrast, forces due to the fastening screws on the connection flange is exposed, whereas it may consist of solid material. Thereby the advantage of a light hollow carrier can be used without the fear that the hollow section will be compressed during attachment.

In a further development of the invention, the carrier is designed as a double-T-carrier and has a height which corresponds to the height of the connection head.

In this way, the end webs of the double-T carrier and the cover surface and the bottom surface of the connection head can be flush. This creates ideal conditions to hang on connection head and carrier floor panels.

In a further development of the invention, a height of the inserted into the receiving chamber on the end face of the carrier coupling part is smaller than a distance between the lid surface and the bottom surface of the connection head.

In this way, when pivoting the coupling part between the cover surface and the bottom surface of the connection head some space available, so that the carrier during pivoting does not necessarily have to be aligned exactly perpendicular to the central longitudinal axis of the connection head.

The problem underlying the invention is also solved by a system for creating structures with at least two carriers according to claim 5, wherein the carrier are formed as a double-T-carrier and at both end webs on both sides of the central web to the respective opposite end web opened longitudinal grooves have, wherein a connecting flange with a lateral stop surface in two opposite longitudinal grooves can be fastened, wherein one of the carrier is provided at one end with a front-side receiving chamber and wherein a section wise arranged in the receiving chamber and in sections over the end of the carrier projecting coupling part is provided, which is fastened to the lateral stop surface of the connecting flange.

In this way, the possibility is created, two double-T-carrier in a simple manner, for example, at right angles, to connect together. The connection flange can be used and fastened in a particularly simple manner in the two opposite longitudinal grooves. The position of the connecting flange can thus be selected arbitrarily along the longitudinal grooves and structures can therefore be planned extremely flexibly with the system according to the invention. For attachment of the carrier to the connection flange of this can be pivoted laterally between the longitudinal grooves until the coupling member abuts against the stop surface of the connection flange. Advantageously, a height of the coupling part in its projecting beyond the end of the carrier area selected smaller than a distance between the two end webs of the double-T-beam. When inserting the carrier must therefore not be located exactly in the height position in which he is finally attached to the flange.

Further features and advantages of the invention will become apparent from the claims and the following description of the invention taken in conjunction with the drawings. Individual features of the embodiments of the invention shown in the different figures can be combined with one another in any desired manner, without exceeding the scope of the present application.

Various illustrations of a system for creating structures according to a further embodiment of the invention when attaching a carrier.

In the presentation of the Fig. 1 a system according to the invention for constructing structures according to a first embodiment of the invention is shown, wherein by way of example a corner connection obliquely from the front and obliquely from above is shown. The corner joint is part of the supporting structure of a two-storey exhibition stand. The corner joint has a vertical column 10, on the upper end side of a connection head 12 is attached. At the connection head 12, in turn, two carriers 14 and 16 are attached at right angles to each other. The carriers 14, 16 are each formed as a double-T-carrier and each have one Middle web 18 and two opposite end webs 20 and 22, respectively.

The connection head 12 has a bottom plate 24 and a cover plate 26, which are arranged parallel to each other and each having a square shape. The bottom plate 24 is secured by means not shown screws on the front side of the column 10.

Between the bottom plate 24 and the cover plate 26 a total of four plate-shaped connecting flanges 28, 30, 32 and 34 are arranged. The fourth connection flange 34 is merely in the illustration of Fig. 2 to recognize.

The connecting flanges 28, 30, 32 and 34 are each formed as elongated metal plates and parallel to a in Fig. 1 not shown center longitudinal axis 58 of the connection head 12 between the bottom plate 24 and cover plate 26 is arranged.

The connecting flanges 28, 30, 32 and 34 each carry two spaced passage openings, which are provided with an internal thread. Already in the presentation of the Fig. 1 It can be seen that the connecting flanges, for example the connecting flange 30, and a contact surface 36 of the connecting flange 30 are laterally offset with respect to a radial plane to the central longitudinal axis. The connecting flange 30 and the stop surface 36 are thereby offset from the center of the connecting flange 12 out. This can be seen for example from the fact that a center groove 38 of the column 10 in the illustration of Fig. 1 not aligned with a front edge of the connecting flange 30. The contact surface 36 is also arranged parallel with respect to the imaginary, radial to the central longitudinal axis plane. In this way, a carrier can be applied laterally to the contact surface 36 and secured thereto, and yet can be a center plane of the carrier then with the Center longitudinal axis of the connection head 12 are aligned. The lateral application of the carrier or a still to be explained coupling part of the carrier to the contact surface 36 of the connection flange 30 is easy to do, since the carrier does not have to be lifted above the connection head 12.
In the presentation of the Fig. 1 and Fig. 2 It can be seen that the carrier 14 is attached by means of a non-visible coupling part on the connecting flange 34 and that the carrier 16 by means of a in Fig. 2 recognizable coupling member 40 is attached to the connecting flange 32. Either Fig. 1 as well as Fig. 2 It can be seen that the carrier 14, 16 are fixed exactly centered to the connection head 12 and that their respective center planes intersect exactly in the central longitudinal axis of the connection head 12.

The carriers 14, 16 are formed as a hollow profile and have a receiving chamber 42 within their central web. In the example of the carrier 16, the coupling part 40 is partially inserted into this receiving chamber 42 and is then secured by means of two bolts 44 in the receiving chamber 42. Two further bolts 46 serve to press the coupling member 40 against the abutment surface of the abutment flange 32 and thus secure the coupling member 40 and thus also the carrier 16 to the connecting flange 12.

The carrier 16 is constructed identically to the carrier 14 and has a central web and two mutually opposite end webs 48, 50. On both sides of the central web, these end webs 48, 50 form grooves which open in each case to the opposite end web 48 or 50. On the upper surfaces of the end webs 48, 50, a groove is provided centrally in each case, which forms an undercut.

The side view of Fig. 3 shows in broken representation the carrier 16, which is provided at both ends with coupling parts 40, 52. It It can be seen that the height of the coupling parts 40, 52 is smaller than the total height of the carrier 16 and also smaller than a distance between the bottom plate 24 and the cover plate 26 of the connection head 12 and smaller than a distance between the lower end bar 50 and When mounting the carrier 16 on the connection head 12 of this can thereby easily tilted between the bottom plate 24 and the cover plate 26 are inserted and only when inserting the bolt 46, the carrier 16 must take its exact intended position.

The presentation of the Fig. 4 shows the coupling part 40 in a front view and a side view. The coupling part 40 is made of solid material, is generally plate-shaped and has in its upper and lower portions in each case a thickened web 54, 56. The thickness of the webs 54, 56 is dimensioned so that they rest against the inner walls of the receiving chamber 42 and the webs 54, 56 are also each provided with holes for the passage of the bolts 44, 46. Although the carrier 16 is designed as a very lightweight aluminum hollow profile, by attaching means of the coupling member 40 is not to be feared that the carrier 16 would be damaged by tightening the bolts 44. The system according to the invention thus makes it possible to create lightweight and highly stable structures that are easy to assemble and disassemble. This is especially important in trade fair construction.

The presentation of the Fig. 5 shows the connection head 12 alone. Also in the view of Fig. 5 only three connection flanges 28, 30 and 32 can be seen, the fourth connection flange 34 is in the illustration of Fig. 5 covered. The four connecting flanges 28, 30, 32, 34 are arranged at an angle of 90 ° to each other and each laterally offset to a plane radial to the central longitudinal axis 58. Such an imaginary radial plane is in the representation of Fig. 5 indicated by dashed lines and it is closed recognize that the abutment surface 36 of the connecting flange 30 is arranged parallel to this imaginary radial plane 60 and offset laterally to this. Since the connection flange 30 itself is laterally offset from this radial plane 60, the carrier or a coupling part of a carrier can be pushed laterally onto the connection flange 30 and fastened thereto, and yet a center plane of the carrier can correspond to the radial plane 60 of the connection flange 12 , The other connecting flanges 28, 32 and 34 are also each arranged laterally offset from an imaginary radial plane and also their respective contact surface is parallel to such a radial plane and arranged laterally offset therefrom. Overall, this results in a center axis 58 axisymmetric design of the connection flange 12th

The presentation of the Fig. 6 shows a connecting flange 62, which is intended to be inserted between the two end webs 48, 50 of the carrier 16. As in the presentation of Fig. 7 can be seen, the connecting flange 62 is inserted for this purpose with its upper or lower end in a longitudinal groove on the upper end web 48 and the lower end web 50. In the desired position on the support 16, the connecting flange 62 is then locked by the fact that 64 pins are inserted into its upper transverse web, which then press against the bottom of the longitudinal groove on the upper end web 48. As a result, the connecting flange 62 is clamped between the two end webs 48, 50 and held immovably in its position.

Another carrier 66 is provided on its one end face with a coupling part 68 and can then be attached to the connecting flange 62. For fixing the carrier 66 to the connecting flange 62, as shown in FIG FIGS. 7, 8 and 9 can be seen, the carrier 66 is first arranged obliquely to the carrier 16 and then pivoted in a direction perpendicular to the carrier 16 position. If the carrier 66 then one to the carrier 16 vertical position, see Fig. 8 , This is moved downward until the coupling member 68 rests with its lower end on the upper edge of the lower end web 50. Starting from this position, the carrier 66 can then, see Fig. 9 , are pushed to the connecting flange 62 parallel to the support 16 until the coupling part 68 abuts against the lateral stop surface of the connecting flange 62. In this position, the coupling part 68 can then be firmly connected by means of two bolts with the connecting flange 62.
