Description

[0001] The invention relates to a supporting structure with a grating that can be attached to at least two opposite supports.

[0002] A generic support structure is known, for example, from document EP 2 227 610 B1. This support structure rests with its grating on two opposing beams. Resting the support structure on the opposing beams increases the overall height. However, there are applications where the lowest possible height is desirable. The height of the beams cannot be easily reduced, as a specific cross-section is required for strength reasons.

[0003] Other generic support structures are known in which a suspension bracket is used to suspend the actual grating, which usually consists of load-bearing and cross-member bars, from the aforementioned supports. These include purely welded constructions in which the bracket is welded to the load-bearing bars, as well as constructions in which the required strength is achieved through a positive fit and additional welded joints. In these cases, the required load-bearing capacity can be achieved through the positive fit alone, but welding is still required to ensure that the suspension bracket does not detach from the load-bearing bar.

[0004] The object of the invention is to provide a supporting structure with a grating which can be attached to at least two opposing supports without the overall height of the structure being significantly increased compared to the height of the supports, which ensures sufficient strength and safe handling without welded joints.

[0005] This object is achieved by the features of claim 1. According to the invention, a support structure is provided with a grating that can be placed on two opposite supports, wherein the grating has support bars and filler bars arranged at an angle thereto and connected to the latter. At least one support bar, but preferably all of the support bars, is engaged by at least one suspension bracket that has a first leg that can be placed on one of the supports and a second leg that engages with the underside of the support bar, wherein these two legs are connected via a connecting leg that rests against the end face of the support bar. The second leg has an upwardly angled end region that engages in a recess in the support bar on its underside.Furthermore, a height adjustment is provided on the underside of the support rod in the area where the second leg engages. This means that the height of the support rod is reduced in this area.

[0006] In this way, a compact structure is created which is connected to the support rod by a suspension bracket which engages with the support rod via several legs or surfaces, so stably that a welded connection is no longer necessary.

[0007] Advantageously, the recess on the support rod has a height that is at least equal to the thickness of the second leg of the suspension bracket. A design in which the recess corresponds to the thickness of the second leg has proven effective, resulting in a compact structure with a seamless contour on the underside of the support rod.

[0008] A particularly strong connection between the suspension bracket and the support rod is achieved when the angled end section and the corresponding recess in the support rod form an angle other than 90° with the underside of the support rod. The angled end section or the corresponding recess in the support rod can be inclined towards the end of the support rod against which the connecting leg rests. This is the preferred embodiment, which results in a particularly stable connection between the suspension bracket and the support rod by essentially clamping the suspension bracket to the support rod. In principle, a similar effect can also be achieved if the angled end section with the corresponding recess in the support rod is inclined in the opposite direction, i.e. away from the end of the support rod against which the connecting leg rests, i.e. in the opposite direction.

[0009] The definition of the inclined, angled end section or the corresponding recess of the support bar can also be defined with respect to the end face of the support bar against which the connecting leg rests. In this case, an inclined, angled end section and a corresponding recess of the support bar can be defined by an angle other than 90° between the recess and the end face of the support bar against which the connecting bracket rests.

[0010] The clamping of the suspension bracket to the support rod can be further improved or increased by giving the angled end section a corrugated and / or angled shape. Advantageously, the recess in the support rod also has a corresponding cross-section. While this does not increase the load-bearing capacity of the structure, it does further reduce the risk of the suspension bracket accidentally becoming detached from the support rod.

[0011] For manufacturing reasons, a design in which the end face of the support bar forms a 90° angle to its top and bottom surfaces is generally preferred. Accordingly, the suspension bracket is designed so that the connecting leg also forms a 90° angle to the first and second legs. However, a solid connection between the elements can also be achieved using a design in which the end face of the support bar forms a different angle to the top and bottom surfaces of the support bar. The suspension bracket follows this contour, so that the connecting leg also forms an angle other than 90° to the first and second legs.Particularly in such a construction, but not necessarily in such a construction, it is also possible for the angled end section and the corresponding recess in the support rod on its underside to have an angle of 90° to the underside of the support rod. If the support structure is to be realized with such an angled end section or corresponding recess in the support rod and an end face of the support rod that is formed at a 90° angle to the top and bottom sides, and a corresponding connecting leg, the angled end section has a corrugated and / or angled cross-section to ensure sufficiently secure clamping of the suspension bracket or anchoring of the suspension bracket to the support rod.

[0012] To increase overall strength, the end face of the support bar can be provided with a projection that engages a recess on the connecting leg of the suspension bracket. The projection and recess preferably have corresponding cross-sections. A square or triangular shape, viewed from the side of the support bar, has proven effective.

[0013] The secure attachment of the connecting leg to the front side of the support bar and the second leg of the suspension bracket to the underside of the support bar is increased if the transition from the front side of the support bar to its underside is provided with a rounding or chamfer, since the inner contour of the suspension bracket usually has a certain rounding in this area.

[0014] The invention is described in more detail using preferred embodiments. Fig. 1 shows the support bar with mounted suspension bracket in the upper section, the support bar without suspension bracket in the lower section on the left, and an alternative support bar end on the right. Fig. 2 shows a first variant of the supporting structure. Fig. 3 shows a second variant of the supporting structure. Fig. 4 shows a third variant of the supporting structure. Fig. 5 shows a fourth variant of the supporting structure in which the front side of the supporting rod has an angle other than 90° to the top and bottom of the supporting rod. Fig. 6 shows a fifth variant similar to the variant according to Fig. 5 with a likewise inclined end face of the support rod, whereby the suspension angle is additionally provided with a projection which engages in a corresponding recess on the support rod.

[0015] Fig. 1 shows a first exemplary embodiment in cross-section. In the lower section, the support bar 2 is shown on its own, with the right-hand illustration showing an alternative design of the end face of the support bar 2. In the upper section, the support bar 2 is shown together with the suspension bracket 1 for placing on a beam 10. Furthermore, the upper illustration shows the filler bars 3 running transversely to the support bar 2. Only one side of the support structure is shown in the figures. The grating consists of support bars 2 and filler bars 3, which are inserted into corresponding recesses in the support bars 2. In the specific exemplary embodiment, the filler bars 3 are arranged at a right angle to the support bars 2, and the recess for receiving the filler bars 3 is provided on the upper side of the support bars 2 such that the upper side of the filler bars 3 is flush with the upper side of the support bars 2.

[0016] The grating, which essentially consists of support bars 2 and filler bars 3, is connected to a support 10 via suspension brackets 1, which are connected to the support bars 2 on the one hand and can be placed on a support 10 on the other. In the specific exemplary embodiment, which is shown here in cross-section, the suspension bracket 1 is provided as a continuous piece. This means that it extends across the entire width of the grating and engages with all support bars 2 of the grating. The suspension brackets 1 of the preferred exemplary embodiments described here all have a first leg 1a, which serves to rest on a support 10, and a second leg 1b, which engages beneath the support bar 2 and engages with the support bar 2 by means of an angled end region 1d.The first leg 1a and the second leg 1b are further connected to a connecting leg 1c, which, in the embodiments described here, rests against the end face 2a of the support rod 2. According to the invention, the support rods 2 have a recess 4 on the underside in the front area, i.e., the area following the end face 2a, by means of which the height of the support rod 2 is reduced at its end. The dimensioning of the recess 4 corresponds approximately to the thickness of the suspension bracket 1, so that, as can be seen from . Fig. 1 and the other figures, after mounting the suspension bracket 1 on the support rod 2, an essentially flat design without projections or recesses results on the underside of the support structure.

[0017] The angled end portion 1d of the suspension bracket 1 engages in a corresponding recess 5 of the support rod 2. This recess 5, or the orientation of the angled end portion 1d, is provided at an angle of >90° to the underside of the support rod 2 and, in this embodiment, in which the end face 2a of the support rod 2 is designed at a right angle to the top and bottom of the support rod 2, has an angle of <90° to the end face of the support rod 2.

[0018] As shown, the legs 1c, 1b of the suspension bracket 1 rest against corresponding surfaces of the support rod 2. Since the suspension bracket 1 in the specific embodiment is a bent metal part with specific radii between the individual legs, the desired flat contact is achieved by a rounded portion 6 of the support rod between the front and the bottom, without requiring particularly high manufacturing tolerances. Alternatively, a conventional chamfer can also be provided here.

[0019] Due to the angled recess 5, with its end pointing diagonally upwards, and the corresponding design of the suspension bracket 1, as well as the arrangement of the lower leg 1b in a corresponding recess 4 of the support bar 2, when the grating is loaded with the support bars 2 and the filler bars 3, the suspension bracket 1 tilts or spreads within the support bars 2, thus easily creating a stable connection. Immediately after mounting the suspension bracket 1 on the support bar(s) 2, the suspension bracket 1 is already anchored to the support bar(s) 2, even without any separate load on the grating, ensuring safe handling.

[0020] In the lower right area of ​​the Fig. 1 shows an alternative support rod end. In this design, the end face 2a of the support rod 2 has a projection that, viewed from the side of the support rod 2, has a triangular cross-section in a longitudinal section along the support rod 2. Correspondingly, in this alternative embodiment, a corresponding recess for receiving the projection 7 is provided on the suspension bracket 1. This creates an even further improved connection between the suspension bracket 1 and the support rod 2.

[0021] In the following description of further variants, only the differences to the one with Fig. 1 illustrated embodiment.

[0022] According to the embodiment according to Fig. 2 and Fig. 3, the recess 5 on the support rod 2 is also designed at an angle <90° relative to the end face 2a of the support rod.

[0023] However, the recess 5 is provided with an angle in its end area, just like the angled end area 1d of the suspension bracket 1. This results in an even stronger wedging of the suspension bracket 1 on the support rod 2. According to Fig. 2, the end surface of the recess 5 facing away from the end face 2a is designed at an angle of >90° to the underside of the support rod 2.

[0024] According to the embodiment according to Fig. 3 a 90° angle is provided here.

[0025] As already explained, in this case a corresponding recess or a corresponding recess is provided on the suspension bracket 1 to accommodate the projection 7.

[0026] The embodiment according to Fig. 4 basically corresponds to the embodiment according to Fig. 3, wherein the projection 7, viewed from the side, has a square cross-section instead of a triangular cross-section.

[0027] In the embodiment according to Fig. 5 is a variant of the embodiment according to Fig. 1, in which the end face 2a of the support rod 2 is inclined, i.e. has an angle other than 90° with respect to the top and bottom of the support rod 2. In the specific embodiment, the end face 2a has an angle <90° with respect to the bottom and an angle >90° with respect to the top. In principle, such an inclined design of the end face 2a can also be implemented in the opposite direction. As can be seen from the figure, the suspension bracket 1 is designed accordingly, i.e. the connecting leg 1c is arranged at an angle other than 90° with respect to the first leg 1a and the second leg 1b. In the specific case, the angle between the connecting leg 1c and the first leg 1a or the second leg 1b is less than 90°. If the end face 2a of the support rod is inclined in the opposite direction, the suspension bracket will have angles greater than 90°.

[0028] A construction with, compared to the embodiment according to Fig. 5 oppositely inclined front surface 2a shows the Fig.6. In this embodiment, the end face 2a of the support rod 2 has a recess 8 which, as shown, engages with a corresponding projection 9 on the suspension bracket 1. The projection 9 on the suspension bracket 1 is achieved by a notch in the material and projects towards the support rod 2. The cross-section is preferably triangular or square when viewed from the side. A lower surface of the projection preferably runs approximately in the direction of the support rod 2. As can be clearly seen from the figure, this results in an extremely good and secure locking of the support rod 2 and suspension bracket 1 in the assembled state. Of course, in the embodiments described so far, instead of a projection at the end of the support rod, a recess and a corresponding projection can be provided there on the suspension bracket 1.
