Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision walls, in particular to a municipal road anti-collision wall. Background Art

[0002] In the existing municipal road and bridge construction, crash walls, as important components for protecting bridge structures, have always attracted much attention for their design and application.

[0003] Traditional crash barriers usually adopt a rigid structure design. When a car collides with it, due to the lack of an effective energy absorption mechanism, the impact energy will be directly transferred to the car and the driver and passengers, causing serious injuries. This rigid design not only fails to effectively protect the safety of the driver and passengers, but may also aggravate the consequences of the accident. In addition, the poor energy absorption performance will also cause the crash barrier to be easily damaged when it is hit, and it cannot effectively play its protective role. For this reason, we propose a municipal road crash barrier. Utility Model Content

[0004] The purpose of the utility model is to provide a municipal road anti-collision wall to solve the problems raised by the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a municipal road crash barrier, comprising a crash barrier body, a plurality of collapse grooves are opened on one side of the crash barrier body, an energy absorption box is installed inside the collapse groove, and an integral plate is installed on one side of the plurality of energy absorption boxes;

[0006] A plurality of collapse guiding grooves are arranged on the outer side of the energy absorption box, and the collapse guiding grooves are distributed along the axial direction of the energy absorption box.

[0007] Preferably, a reflective strip is bonded to one side of the integrated panel.

[0008] Preferably, a plurality of reinforcing plates are integrally formed on the inner side of the energy absorption box, and reinforcing tubes are integrally formed between the plurality of reinforcing plates.

[0009] Preferably, the energy absorption box, the reinforcement plate and the reinforcement tube are all made of aluminum alloy.

[0010] Preferably, a connection frame is installed on one side of the integrated plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When the integrated panel of the municipal road crash barrier is hit, it moves toward the crash barrier body and compresses the energy absorption box. The energy absorption box can absorb part of the energy generated by the car collision until the integrated panel hits the crash barrier body. The crash barrier body and the integrated panel stop the car and prevent it from leaving the road. The energy is absorbed by the collapse of the energy absorption box, which protects both the car and the crash barrier body and reduces impact damage.

[0013] 2. The municipal road crash barrier reserves a collapse space for the energy absorption box through the collapse groove, and the collapse guide groove can play a collapse guide effect, so that the collapsed energy absorption box can enter the collapse groove, thereby improving the energy absorption effect and further reducing impact damage.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Embodiment 1

[0020] Please refer to Figure 1-3 As shown, the utility model provides a municipal road crash barrier, including a crash barrier body 1, a plurality of collapse grooves 2 are opened on one side of the crash barrier body 1, an energy absorption box 3 is installed inside the collapse groove 2, and an integrated plate 4 is installed on one side of the plurality of energy absorption boxes 3;

[0021] A plurality of collapse guide grooves 9 are provided on the outer side of the energy absorption box 3 , and the collapse guide grooves 9 are distributed along the axial direction of the energy absorption box 3 .

[0022] Specifically, when the integrated panel 4 is hit, the integrated panel 4 moves toward the direction close to the crash wall body 1 and compresses the energy absorbing box 3. The energy absorbing box 3 can absorb part of the energy generated by the collision of the car until the integrated panel 4 hits the crash wall body 1. The crash wall body 1 and the integrated panel 4 stop the car and prevent the car from leaving the road. The energy is absorbed by the collapse of the energy absorbing box 3, thereby reducing the damage to the crash wall body 1 and the car.

[0023] Wherein: a reflective strip 6 is bonded to one side of the integrated plate 4, and the reflective strip 6 is used to warn vehicles.

[0024] Among them: a plurality of reinforcing plates 7 are integrally formed on the inner side of the energy absorbing box 3, and reinforcing tubes 8 are integrally formed between the plurality of reinforcing plates 7. The energy absorbing box 3, the reinforcing plates 7 and the reinforcing tubes 8 are all made of aluminum alloy. The reinforcing plates 7 and the reinforcing tubes 8 can improve the overall strength of the energy absorbing box 3, thereby increasing the energy absorption performance.

[0025] Wherein: a connection frame 5 is installed on one side of the integrated plate 4, and the integrated plate 4 covers the energy absorption box 3, so that the anti-collision wall has better integrity.

[0026] Working principle: The utility model is a municipal road crash barrier. When the integrated plate 4 is hit, the integrated plate 4 moves toward the crash barrier body 1 and compresses the energy absorption box 3. The energy absorption box 3 can absorb part of the energy generated by the collision of the car until the integrated plate 4 hits the crash barrier body 1. The crash barrier body 1 and the integrated plate 4 stop the car and prevent the car from leaving the road. The energy absorption box 3 collapses and absorbs energy, which protects the car and the crash barrier body 1 and reduces the impact damage.

[0027] The crush groove 2 reserves a crushing space for the energy absorbing box 3, and the crush guiding groove 9 can play a crushing guiding effect, so that the crushed energy absorbing box 3 can enter the crush groove 2, thereby improving the energy absorption effect.
