Description

Technical Field

[0001] The utility model relates to the technical field of slope personnel evacuation protection measures, in particular to a modular anti-collapse guardrail at a slope. Background Art

[0002] The main entrances and exits of civil air defense serve as life passages to ensure the normal entry and exit of personnel in wartime. When personnel are evacuated during wartime, the evacuation ramp is within the collapse range and anti-collapse scaffolding must be installed to prevent the entrance from being blocked. The anti-blocking scaffolding will not collapse under the predetermined shock wave and collapse load of ground buildings, thereby improving safety.

[0003] Deficiencies of existing technology:

[0004] At present, the general approach to preventing collapse is to pile up sandbags on the boundary line of the collapse range. Stacking sandbags is bulky and labor-intensive, and cannot completely guarantee that the evacuation passage will not be blocked by falling objects. The sandbags themselves may also be dispersed and collapsed by the shock wave. Not only can it not guarantee the safe evacuation of personnel, it may also endanger personal safety. Utility Model Content

[0005] The purpose of the utility model is to provide a modular anti-collapse guardrail at a ramp to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a modular anti-collapse guardrail at a ramp, comprising a ramp structure plate, the ramp structure plate is provided with an anti-collapse component, and the anti-collapse component comprises:

[0007] Guardrail vertical poles, the guardrail vertical poles are connected by a connecting assembly;

[0008] A high-strength screw is arranged at the bottom of the vertical upright pole of the guardrail.

[0009] Preferably, the connecting assembly includes a fixing plate and a connecting rod, the guardrail vertical pole is vertically arranged on the fixing plate, and the connecting rod is arranged on the top of the guardrail vertical pole.

[0010] Preferably, a structural reserved groove is provided inside the ramp structural plate to match the position of the vertical upright pole of the guardrail.

[0011] Preferably, the vertical upright pole of the guardrail can move up and down on the fixed plate.

[0012] Preferably, when the vertical upright pole of the guardrail runs to the reserved groove of the structure, the high-strength screw can be extended in a T-shape.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The modular anti-collapse guardrail at a ramp is provided with an anti-collapse component, which includes a vertical pole of the guardrail and high-strength screws. A structural reserved groove needs to be opened inside the ramp structure plate, and a fixing plate is placed on the ramp structure plate. When the vertical pole of the guardrail is installed, the connecting rod is pressed to make the vertical pole of the guardrail enter the structural reserved groove downward. The high-strength screws at the bottom of the vertical pole of the guardrail extend in a T-shape inside the structural reserved groove and are completely anchored inside the structural reserved groove. The anti-collapse guardrail has a small size and is easy to install, and reduces labor. In addition, a certain resistance level of the anti-collapse guardrail can be obtained, so as to prevent falling objects from blocking the evacuation passage and ensure the orderly and normal evacuation of personnel.

When the guardrail vertical pole 121 is installed, the connecting rod 132 is pressed to make the guardrail vertical pole 121 enter the structure reserved groove 140 downward, and the high-strength screw 122 at the bottom of the guardrail vertical pole 121 extends in a T-shape inside the structure reserved groove 140 and is completely anchored inside the structure reserved groove 140. It has a small volume and is easy to install, so that a certain resistance level of anti-collapse guardrail can be obtained, thereby achieving the requirement of preventing falling objects from blocking the evacuation channel and ensuring the orderly and normal evacuation of personnel.

[0023] Furthermore, for example, in a densely populated area, the main entrance and exit of the civil air defense project in wartime is located at the car ramp. The net width of this ramp is 7m, and the collapsed range has occupied 5m. The wartime evacuation path is 2m wide and is located outside the collapse range. Since the ramp surface is in the same space, it is necessary to run out of the ground along the prescribed path to evacuate in a dispersed manner. In the case that it cannot be guaranteed that the falling objects within the collapse range will not completely block the evacuation path, guardrail vertical poles 121 are set at the 2m and 5m dividing line positions to effectively prevent the rolling of falling objects and ensure that they cannot block the evacuation passage, thereby ensuring the safe evacuation of personnel.

[0024] The working principle of the utility model is as follows:

[0025] When a modular anti-collapse guardrail at a ramp of the present embodiment is in use, during construction, a structural reserved groove 140 needs to be opened inside the ramp structure plate 110, and the fixing plate 131 is placed on the ramp structure plate 110. When the guardrail vertical pole 121 is installed, the connecting rod 132 is pressed so that the guardrail vertical pole 121 enters downward into the structural reserved groove 140, and the high-strength screw 122 at the bottom of the guardrail vertical pole 121 extends in a T-shape inside the structural reserved groove 140 and is completely anchored inside the structural reserved groove 140. It is small in size and easy to install, so that the guardrail vertical pole 121 with a certain resistance level can be obtained, thereby achieving the requirement of preventing falling objects from blocking the evacuation channel and ensuring the orderly and normal evacuation of personnel.

When the guardrail vertical pole 121 is installed, the connecting rod 132 is pressed to make the guardrail vertical pole 121 enter the structure reserved groove 140 downward, and the high-strength screw 122 at the bottom of the guardrail vertical pole 121 extends in a T-shape inside the structure reserved groove 140 and is completely anchored inside the structure reserved groove 140. It has a small volume and is easy to install, so that a certain resistance level of anti-collapse guardrail can be obtained, thereby achieving the requirement of preventing falling objects from blocking the evacuation channel and ensuring the orderly and normal evacuation of personnel.

[0027] Furthermore, for example, the main entrance and exit of the civil air defense project in a densely populated area is located at the non-motorized ramp, and the non-motorized ramp is just at the critical point of the collapse range line. Since it is at the critical point, it cannot be completely confirmed that falling objects will not fall into the ramp for various reasons and injure people or block the entrance and exit. Therefore, a guardrail vertical pole 121 is set on the low wall on the side of the ramp to ensure that the collapsed objects cannot block the evacuation passage and ensure the safe evacuation of personnel.

[0028] The working principle of the utility model is as follows:

[0029] When a modular anti-collapse guardrail at a ramp of the present embodiment is in use, during construction, a structural reserved groove 140 needs to be opened inside the ramp structure plate 110, and the fixing plate 131 is placed on the ramp structure plate 110.
