Problems solved by technology

[0005] In view of the related technologies mentioned above, the inventor believes that there are the following defects: in the actual use of the road, due to various reasons such as accident avoidance, road congestion, curiosity, convenience at night, etc., people often leave the vehicle to climb over and climb on the bridge. Behaviors such as climbing and clinging, especially at night and in low visibility conditions such as heavy fog, can easily ignore bridge gaps and cause bridge falling accidents

Embodiment 1

[0042] refer to figure 1 and figure 2 A kind of anti-falling safety facility for the central divider of an expressway bridge comprises two oppositely arranged concrete guardrails 1, the two concrete guardrails 1 respectively belong to two adjacent bridges, and the central divider is between the two concrete guardrails 1; A safety protection net 2 is arranged horizontally between the two concrete guardrails 1, and a plurality of transverse reinforcement ropes 3 and a plurality of longitudinal reinforcement ropes 4 are arranged horizontally below the safety protection net 2, and the transverse reinforcement ropes 3 are all perpendicular to the two concrete guardrails. 1 the opposite side walls, the longitudinal reinforcement ropes 4 are parallel to the opposite side walls of the two concrete guardrails 1, all the transverse reinforcement ropes 3 and all the longitudinal reinforcement ropes 4 are fixed to each other, the opposite sides of the safety protection net 2 and all Bot...

Embodiment 2

[0049] refer to Figure 4 , The difference from Embodiment 1 is that there are gaps between the transverse reinforcement rope 3 and the safety protection net 2, and between the longitudinal reinforcement rope 4 and the safety protection net 2. When the safety protection net 2 is under pressure, it first produces a certain degree of deformation to offset a part of the pressure. The transverse reinforcement rope 3 and the longitudinal reinforcement rope 4 provide support for the safety protection net 2, which improves the strength of the transverse reinforcement rope 3 and the longitudinal reinforcement rope. 4 service life.

Embodiment 3

[0051] refer to Figure 5 and Figure 6 , The difference from Embodiment 1 is that each hook 6 is provided with an anti-unhook mechanism 8 for preventing the thickened side rope 5 from detaching from the hook 6 . The top of the hook end 62 is provided with a vertically arranged pressing groove 621, and the bottom of the pressing groove 621 is provided with an accommodating groove 622, and the opposite sides of the accommodating groove 622 are provided with horizontal sliding holes; The bent portion 71 is hollow in the middle, and the two sides of the bent portion 71 are respectively located on opposite sides of the hook end 62 , and the openings of the two sliding holes are respectively located inside the two sides of the bent portion 71 .

[0052] refer to Figure 5 and Figure 6 The anti-decoupling mechanism 8 includes a pull column 81 slidably connected in the pressing groove 621, two connecting rods 82 hinged at the bottom end of the pull column 81 and located in the re...

Abstract

The invention relates to an expressway bridge medial strip anti-falling safety facility, which belongs to the technical field of expressway safety facilities. The expressway bridge medial strip anti-falling safety facility comprises two concrete guardrails which are oppositely arranged, a safety protection net is arranged between the two concrete guardrails, a plurality of transverse reinforced ropes and a plurality of longitudinal reinforced ropes are arranged below the safety protection net, and all the transverse reinforced ropes and all the longitudinal reinforced ropes are mutually fixed; thickened side ropes are fixed to the two sides, close to the concrete guardrails, of the safety protection net and the two ends, close to the concrete guardrails, of the transverse reinforced ropes, the opposite side walls of the two concrete guardrails are each fixedly provided with a row of hooks, the thickened side ropes are hung on the row of hooks, and each hook is provided with an anti-unhooking mechanism used for preventing the thickened side ropes from being separated from the hooks. The facility has the effects of improving the road traffic safety and preventing and reducing the falling accidents of the expressway bridge medial strip.

Description

technical field [0001] The present application relates to the technical field of expressway safety facilities, in particular to an anti-falling safety facility for the middle divider of expressway bridges. Background technique [0002] Most expressway bridges in our country adopt left and right framing structures, and vehicle safety is mainly considered in the design. Most of the traditional expressway protection nets are vertical safety nets, which can only prevent overturning. [0003] In recent years, there have been frequent reports of falling accidents in the middle of expressway bridges, which have caused great social repercussions. The problem of falling in the gap between bridges can no longer be ignored. How to prevent and reduce the occurrence of such accidents is an issue for every bridge engineer. Questions that must be considered. [0004] The existing expressway is divided into two adjacent bridges, and the two edges of the upper surface of each bridge are fix...
