Description

Technical Field

[0001] The utility model relates to the technical field of road traffic engineering construction, in particular to an anti-throwing net fixing seat and a concrete bridge anti-throwing net. Background Art

[0002] The bridge anti-throwing net is an important traffic safety facility. Its main function is to prevent objects from being thrown from the bridge, thereby ensuring traffic safety on the road below.

[0003] There are two structural forms of existing bridge anti-throw nets. One is that a mounting seat is set at the bottom of the anti-throw net column, and a hole is drilled on the top surface of the concrete guardrail, and the mounting seat is fixed to the top surface of the guardrail by expansion bolts. The other form is cast-in-place reinforced concrete. The installation of bridge anti-throw nets usually adopts the pre-buried steel pipe method. The single-layer steel pipe is pre-buried in the corresponding position during the concrete pouring. During installation, the anti-throw net column is directly inserted into the pre-buried single-layer steel pipe to achieve fixation. Both structural forms of bridge anti-throw nets have their own advantages and disadvantages.

[0004] At present, the construction site of the embedded steel pipe method is mainly carried out by pre-embedded construction in advance during the construction of concrete guardrails. After the concrete strength of the guardrail reaches the design requirements, the protective net columns are inserted into the embedded parts, and the gaps between the columns and the embedded parts are filled with concrete. Before the filled concrete reaches the design strength, the columns are prone to tilt when collided, and their verticality and embedded depth cannot be guaranteed. Utility Model Content
