Assembly type guardrail

Abstract

The invention relates to an assembly type guardrail which comprises a leveling layer, a concrete guardrail body and connecting steel bars, and the leveling layer is used for leveling a bridge floor; the concrete guardrail is arranged on one side of the leveling layer; one end of each connecting steel bar is a bridge body end, the other end of the connecting steel bar is a guardrail end, the bridge body end is arranged in the leveling layer in a penetrating mode, the guardrail end is arranged in the concrete guardrail in a penetrating mode, and the part, close to the leveling layer, of the guardrail end transits to the part, close to the concrete guardrail, of the bridge body end in the width direction parallel to the leveling layer. The concrete guardrail is arranged on one side of the leveling layer, the concrete guardrail and the leveling layer are connected through the connecting steel bars, and connection between the leveling layer and the concrete guardrail can be enhanced. When the concrete guardrail is impacted, impact force can be transmitted to the leveling layer from the concrete guardrail along the connecting steel bars, it is guaranteed that the transmission path of the impact force between the concrete guardrail and the leveling layer is clear, the impact force is transmitted to the leveling layer with a larger stress structure, and the structural stability of the concrete guardrail can be effectively protected.

Description

technical field [0001] The invention relates to the technical field of road transport protection equipment, in particular to an assembled guardrail. Background technique [0002] Guardrails are an important part of road bridges, generally located on both sides of the road, which can effectively prevent vehicles from rushing out of the lane and cause more serious accidents. At present, the construction method of concrete bridge guardrail is mostly in the form of pouring on site. That is to pre-buried the anti-collision guardrail anchor steel bars in the bridge deck, and after the main girder construction is completed, the guardrail steel bars are bound on site and the concrete is poured. In the field pouring, the position of the pre-embedded steel bars on the bridge deck is often inaccurate, resulting in insufficient thickness of the protective layer. During the use, there are problems such as leaking bars, concrete rust and cracks, which seriously affect the durability of t...

AI Technical Summary

Problems solved by technology

However, at present, the structure of the prefabricated concrete guardrail and the structure of the bridge are connected in a complicated way. The connection structure between the concrete guardrail and the bridge body is not easy to check. The construction precision is high and the quality cannot be guaranteed. The guardrail structure is easy to be damaged when it is actually hit. destroy
