Description

Technical Field

[0001] This utility model relates to the field of guardrails, and in particular to a protective device for preventing collapse at civil defense entrances and exits. Background Technology

[0002] As an important component of the urban disaster prevention and mitigation system, the stability and reliability of the safety protection facilities at civil defense entrances and exits directly affect the efficiency of personnel evacuation and emergency rescue. Currently, most civil defense entrances and exits use traditional guardrails, which are mostly made of metal and placed at the entrances and exits. However, when the flow of people surges or is subjected to sudden external impacts, the guardrails are prone to tipping over, not only failing to provide protection but also potentially causing secondary injuries to people. Guardrails fixed to the ground or walls by welding or bolting are prone to loosening or breaking due to material fatigue or environmental corrosion during long-term use, leading to a decrease in the stability of the guardrails. At the same time, this installation method lacks the flexibility for quick disassembly and replacement. Utility Model Content

[0003] The purpose of this utility model is to provide a simple structure, easy installation, and a guardrail that, when assembled with a base plate, effectively prevents accidental tipping.

[0004] This utility model is achieved through the following measures: A collapse-proof protection device for civil defense entrances and exits, characterized in that it includes an installation base plate and a plurality of assembled guardrails installed on the installation base plate; The assembled guardrail includes a pair of inclined protective frames, each protective frame including several parallel diagonal braces, each diagonal brace having a horizontal insert at its bottom end, each diagonal brace having a connecting crossbar at its top end, a U-shaped guardrail between the two ends of the connecting crossbar, and several horizontal guardrails on the inner side of the U-shaped guardrail. The mounting base plate is bolted to the ground at the entrance / exit of the civil defense facility; The mounting base plate has several assembly tubes evenly spaced on both sides corresponding to the position of the horizontal insertion rod. One end of each assembly tube is open and the other end is closed. The end of the horizontal insertion rod is inserted into the assembly tube. The connecting crossbars on both sides of the assembled guardrail are connected by connectors.

[0005] The specific features of this utility model also include: The connector includes a connecting plate, and a pair of pipe clamps are provided at the bottom of the connecting plate, the pipe clamps being mounted on the connecting crossbar.

[0006] A ramp is bolted between adjacent assembly tubes and on the side of the mounting base plate to facilitate pedestrian movement.

[0007] An L-shaped rubber support block is provided at the bottom of the connection between the horizontal insert rod and the diagonal brace, and the bottom surface of the L-shaped rubber support block is flush with the bottom of the mounting base plate.

[0008] Warning signs are installed on both sides of the assembled guardrail.

[0009] During the installation of the guardrail, the protective frame of one assembled guardrail is inserted into the corresponding assembly tube. Then, the adjacent connecting crossbars are connected by connectors (the pipe clamps are installed on the corresponding connecting crossbars respectively). After that, the next assembled guardrail is installed according to the required position and quantity.

[0010] The advantages of this utility model are: simple structure, convenient installation, and the combination of assembled guardrail and installation base plate effectively prevents accidental tipping. Attached Figure Description
