Description

[0001] The invention relates to a system for introducing loads into a supporting structure of a building, in particular a parking garage, comprising: at least one impact mat for absorbing loads, in particular loads caused by the impact of a vehicle, wherein the at least one impact mat has a plurality of support bars which preferably run at least partially substantially horizontally, at least one support element, in particular at least one steel support, wherein the at least one support element can be part of the supporting structure of the building, and at least one connecting element for connecting the at least one impact mat to the at least one support element.

[0002] The above-mentioned systems for introducing loads into a supporting structure of a building, in particular into a supporting structure of a parking garage, comprising at least one impact mat for absorbing loads, are already known from the prior art.

[0003] For example, crash mats, also called crash barriers, are used as parapets on parking levels in parking garages and are attached to two spaced-apart support elements, particularly vertical support elements. Such a crash mat can prevent a vehicle from crashing if it crosses the outer boundaries of the respective parking level. Crash mats can also be used to separate two opposing parking rows and for other purposes. In this context, it is also possible to provide the crash mats in question with a covering.

[0004] The aforementioned impact mats are designed, for example, as single-bar mats and regularly comprise essentially horizontally running support bars and essentially vertically running grid bars, which can be welded to form the impact mat.

[0005] Conventional impact mats, especially the end sections of the impact mat support bars, are usually connected to one or more connecting elements by means of a weld seam, whereby the connecting elements can then be subsequently screwed to a support element. However, the provision of these weld seams has proven disadvantageous from a manufacturing and assembly perspective, as the welding step naturally entails additional costs.

[0006] In this respect, the present invention is based on the technical problem of providing a system for introducing loads into a supporting structure of a building, in particular into a supporting structure of a parking garage, which is both cost-effective and advantageous in terms of assembly technology.

[0007] The above-mentioned technical problem is solved according to the invention in a system described at the outset for introducing loads into a supporting structure of a building, in particular into a supporting structure of a parking garage, in that the end regions of the plurality of supporting rods are each clamped between the at least one connecting element and the at least one support element, are connected to the at least one connecting element and the at least one support element by means of a clamping connection and / or can be clamped between the at least one connecting element and the at least one support element.

[0008] As a result, the at least one impact mat can be connected to the at least one support element in a cost-effective and time-efficient manner by means of at least one connecting element.

[0009] The at least one impact mat is designed to absorb an impact or collision of a vehicle and to transmit the resulting forces via the at least one connecting element into the at least one support element or into the supporting structure of the building.

[0010] Preferably, the at least one impact mat comprises a plurality of support bars, wherein the plurality of support bars extend substantially horizontally. Preferably, the plurality of support bars has end regions that extend beyond a mat region of the impact mat, so that the end regions can be clamped between the at least one connecting element and the at least one support element.

[0011] Preferably, the impact mat further comprises substantially vertically extending grid bars arranged in the mat region, wherein the substantially vertically extending grid bars can be welded to the plurality of support bars at intersection points, for example. Furthermore, it is preferred that both the grid bars and the support bars have a substantially round profile.

[0012] In addition, the impact mat may further comprise substantially horizontally extending grid bars arranged in the mat area, which are not designed as support bars within the meaning of the present invention. The substantially horizontally extending grid bars are, for example, welded to the substantially vertically extending grid bars at intersection points.

[0013] The at least one support element preferably extends substantially vertically, so that loads can be absorbed and transmitted, particularly in the direction of the longitudinal axis of the at least one support element. The at least one support element is preferably designed as a steel support or an aluminum support. For example, the at least one support element can be configured as a support profile, with a double-T profile being advantageous.

[0014] The at least one connecting element can, for example, be designed as an elongated rectangular profile. For example, the at least one rectangular profile can be made of a steel alloy or an aluminum alloy.

[0015] The clamping connection between the end regions of at least some of the plurality of support rods and the at least one connecting element and the at least one support element is, in particular, a mechanical connection technique in which, in particular, the aforementioned components are connected to one another by means of clamping forces. The clamping connection is preferably reversible.

[0016] Preferably, the clamped connection is established by clamping and / or clamping the end regions between the at least one support element and the at least one connecting element. This can be achieved, for example, by applying a mechanical force, using, for example, screws, bolts, nuts, clamping rings, and / or clamping plates. Clamping forces can create a secure and stable connection without the need for additional adhesives, solder, and / or welded joints.

[0017] In particular, the end regions substantially protrude laterally beyond a mat region of the at least one impact mat that has intersection points and can thus be conveniently clamped to the at least one support element by means of the at least one connecting element. Thus, the end regions are particularly those regions of the support bars that, starting from an intersection point with a grid bar, no longer have a further intersection point with a grid bar.

[0018] Clamping the end regions between at least one connecting element and at least one support element means in particular that the respective end regions are arranged between the at least one connecting element and the at least one support element in such a way that clamping forces can be exerted by them on the respective end region.

[0019] A further advantageous embodiment is characterized in that the end regions of the support rods, in particular the end regions clamped between the at least one connecting element and the at least one carrier element, each comprise a bent section, wherein the bent section has an angle in a range of 170° to 190°, preferably an angle of substantially 180°, so that the distal ends of the support rods run substantially parallel to the support rods arranged in a mat region of the impact mat. This makes it possible to provide self-locking of the clamped connection between the at least one impact mat, the at least one connecting element, and the at least one carrier element. When the impact mat is loaded by a vehicle, the majority of support rods strive out of the at least one connecting element due to their rope-like behavior.In such a case, the radius of the bent section is narrowed by the aforementioned bent section and the absorbed load can be advantageously introduced into the at least one connecting element or into the at least one support element.

[0020] A further preferred embodiment is characterized in that the distal ends of the plurality of support rods have a diameter-enlarged section to prevent slipping out of the at least one connecting element. This further ensures sufficient load-bearing capacity of the at least one impact mat. For example, the respective diameter-enlarged sections of the plurality of support rods can be provided by an end cap that is integrally connected to the respective support rod.

[0021] A further preferred embodiment is characterized in that the respective end regions of the plurality of support rods are clamped and / or clamped in corresponding grooves of the at least one connecting element.

[0022] By providing grooves in the at least one connecting element, easy alignment of the at least one connecting element during assembly of the at least one impact mat can be enabled. Furthermore, the clamping force exerted on the end regions by the at least one connecting element or the at least one supporting element can be increased, so that the connection also transfers high loads from the impact mat to the supporting structure of the building.

[0023] A further preferred embodiment is characterized in that the at least one connecting element has two grooves associated with a support rod, and in particular, both the distal end and the region of the respective support rod located upstream of the bent section are clamped in corresponding grooves of the at least one connecting element. This further improves the alignment of the bent section of the end region with the at least one connecting element and increases the security of the clamped connection.

[0024] A further preferred embodiment is characterized in that the at least one connecting element is connected to the at least one support element by means of at least one screw connection, so that tightening the at least one screw connection increases the clamping force exerted on the end regions of the support rods. This allows for convenient adjustment of the respective clamping force depending on the installation situation of the at least one impact mat. For this purpose, the at least one connecting element preferably has, for example, an internal thread and / or is provided with a dowel having an internal thread.

[0025] A further preferred embodiment is characterized in that the at least one connecting element has a through-hole, in particular a through-hole designed as a round through-hole or as an elongated hole, for receiving a screw bolt and / or a screw. A screw bolt or a screw is a short, generally cylindrically shaped connecting element which in particular has an external thread. A connection made by a screw bolt or a screw is generally reversible. By providing a through-hole designed as an elongated hole, sufficient play can be provided when attaching the at least one impact mat. If the through-hole is designed as a round through-hole or as a round hole, tolerance compensation can be achieved by moving the connecting element on the support rods.

[0026] A further preferred embodiment is characterized in that at least two separate connecting elements are provided per support element for connecting the at least one impact mat to the respective support element. This provides a connection through which loads occurring during operation can be reliably transferred into the supporting structure of the building. Furthermore, it is preferred that two end regions of the support rods can be connected to the at least one support element by means of a clamp connection, each by means of a connecting element.

[0027] A further preferred embodiment is characterized in that the at least one impact mat is designed as a single-bar mat. Practical tests have shown that the use of a single-bar mat is sufficient to absorb the loads occurring during operation. In this respect, the use of a single-bar mat can save costs compared to a double-bar mat. However, the impact mat can also preferably be designed as a double-bar mat, especially in areas that typically come into contact with vehicles.

[0028] In the following, the invention is explained using exemplary embodiments with reference to the drawing. The drawing shows Fig. 1 a perspective view of an embodiment of a system for introducing loads.

[0029] Fig. 1 shows a system 2 for introducing loads into a supporting structure of a building.

[0030] The system 2 comprises an impact mat 4 for absorbing loads caused by vehicle impacts. It can be seen that the impact mat 4 is designed as a single-bar mat comprising essentially horizontally extending support bars 6 and essentially vertically extending grid bars 8. The support bars 6 are preferably welded to the grid bars 8 at the respective intersection points 10.

[0031] Furthermore, the system 2 comprises two support elements 12 extending essentially in the vertical direction. The support elements are designed in particular as double-T steel beams and are part of the supporting structure of a building, in particular a parking garage.

[0032] Furthermore, the system 2 comprises four connecting elements 14 for connecting the impact mat 4 to the support elements 12. The connecting elements 14 each have four essentially horizontally extending grooves 15.

[0033] The end regions 16 of the support bars 6 have a curved section 18, wherein the curved section 18 has an angle of substantially 180°, so that the distal ends 20 of the support bars 6 run substantially parallel to the support bars 6 arranged in the mat region 22 of the impact mat 4.

[0034] It can be seen that the distal ends 20 of the support rods 6 have a diameter-enlarged section in the form of a closure cap 26, which can prevent the support rods 6 from slipping when loads are being absorbed.

[0035] The respective end regions 16 of the support rods 6 are arranged in the grooves 15 and are braced or clamped to the two support elements 12 by means of the connecting elements 14. For this purpose, the connecting elements 14 each have a through hole, in particular an elongated hole 28, and a screw bolt 30 arranged in the elongated hole 28. By tightening the screw bolt 30, the clamping force exerted on the support rods 6 can be increased. For this purpose, both the distal end 20 and the region 32 of the support rods 6 arranged upstream of the curved section 18 are arranged in the grooves. The distal end 20 and the upstream region 32 of a support rod 6 run essentially parallel to one another due to the curved section 18.
