Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering, in particular to a full-bridge type safety rope structure. Background Art

[0002] Bridge engineering refers to the process of bridge survey, design, construction, maintenance and verification, as well as the science and engineering technology that studies this process. It is a branch of civil engineering. The development of bridge engineering mainly depends on the needs of transportation. Bridge engineering mainly studies bridge design, determines the bridge aperture, considers navigation and line requirements to determine the bridge deck height, considers the base from scouring or frost heave to determine the foundation burial depth, designs diversion buildings, etc.; bridge type design; bridge structure design; bridge construction; bridge verification; bridge testing; bridge maintenance, etc.

[0003] When constructing the bridge deck system in a bridge project, in order to prevent construction workers from falling, the traditional edge protection measures are to set up guardrails and protective nets on the edge. With the large-scale construction of large-span and high-pier bridges, the disadvantages of this traditional edge protection measure, such as high investment, time-consuming, and unreliable, have become prominent, and it can no longer meet the needs of safe production. Especially after the bridge deck is paved, when constructing the guardrail, the traditional guardrail cannot be installed, and there are no edge protection measures. The construction workers are exposed to danger. Once the operation is wrong, it is very likely to fall to death. In view of this, we propose a full-bridge safety rope structure. Utility Model Content

[0008] The upper surface of the bridge base is paved with a filling structure that wraps the gate reinforcement and the base assembly and establishes a stable fixing effect between the bridge base, the gate reinforcement and the base assembly;

[0009] A through hole for accommodating a fixing pipe is formed at a position corresponding to the internal threaded hole inside the filling structure, and a guardrail component for workers to connect safety belts to provide safety protection during construction is detachably provided at a position corresponding to the base component on the surface of the filling structure and cooperates with the internal threaded hole.

[0010] Preferably, a positioning piece is provided in the middle of the embedded frame, and a rubber positioning block is provided in a rectangular array at the bottom of the positioning piece, and arc-shaped positioning grooves are formed on the four sides of the rubber positioning block for adapting and engaging with the door reinforcement to achieve automatic positioning effect during welding.

[0011] Preferably, a reinforcement plate is formed between the block-shaped components corresponding to the corners and the middle parts of the four side surfaces of the positioning member, and a spiral reinforcement structure is formed between the reinforcement plate and the positioning member.

[0012] Preferably, the guardrail assembly includes a guardrail base with a guardrail rod arranged in the center of the top, and countersunk holes are formed at the four inner corners of the guardrail base. Bolts are arranged in the countersunk holes, and the bottom ends of the bolts pass through the through holes and are detachably connected to the threaded holes in the fixing tubes, and the outer cover of the bolt cap is provided with a rubber sleeve for preventing slipping.

[0013] Preferably, a U-shaped receiving piece is symmetrically formed on the outer edge surface of the top end of the guardrail rod, and a rope structure is arranged between the guardrail rods. The rope structure includes a guardrail rope with hanging rings at both ends that can be detachably bound, and the hanging ring is sleeved and connected to the U-shaped receiving piece.

[0014] Preferably, ribs are welded in a circular array on the outer edge surface of the bottom end of the guardrail rod, and the lower end surface of the ribs is welded and fixed to the guardrail base.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. By setting door reinforcement and embedded frames, fixing them by welding, and casting a filling structure between the door reinforcement and the base assembly for further reinforcement, a stable connection structure based on the threaded holes in the fixed pipe can be established on the surface of the filling structure, so that the guardrail assembly can be stably installed with the help of the threaded holes in the fixed pipe as needed, so that workers can connect safety belts with the help of the guardrail assembly to achieve the protection effect of the edge construction of the bridge, which is beneficial to provide protection for the life safety of workers and avoid falling accidents when installing bridge deck guardrails.

[0017] 2. By arranging a rubber positioning block at the bottom of the positioning piece and opening arc-shaped positioning grooves on the four sides of the rubber positioning block, when welding the embedded frame and the door reinforcement, it can be pressed hard to deform the rubber positioning block and make the door reinforcement snap into the arc-shaped positioning groove, so that accurate positioning can be achieved when welding the door reinforcement and the embedded frame, without manual positioning support, which is conducive to improving the welding effect between the door reinforcement and the embedded frame, thereby further improving the stability of workers connecting the safety belt with the help of the guardrail assembly to achieve bridge edge construction protection.
