Outward-wrapped-type anti-collision guardrail formwork reinforcing structure

Abstract

The invention discloses an outward-wrapped-type anti-collision guardrail formwork reinforcing structure. A formwork comprises an outer formwork body and an inner formwork body. The longitudinal section of the outer formwork body is L-shaped, and the bottom of the outer formwork body is bent towards the bottom plane of a bridge and is supported on the bottom plane of the bridge through a supporting foot; the longitudinal section of the inner formwork body is in a broken-line shape, and the bottom face of the inner formwork body is supported on the upper plane of the bridge; ejection ribs are arranged between the outer formwork body and the inner formwork body for supporting and pull rods are arranged between the outer formwork body and the inner formwork body for tensioning. According to the reinforcing structure, the formwork is fixed through the ejection ribs and the pull rods firstly, supports and pull wires are oppositely arranged on a vertical seam between the two adjacent formworks so as to prevent the situation that a joint of the two formworks deforms and accordingly the defect of a concrete faulted slab remains permanently when the concrete is poured, the left of the vertical seam is 10 cm away from the right of the vertical seam, the problem that an outward-wrapped-type anti-collision guardrail formwork is difficult to reinforce is solved, and construction quality is guaranteed.

Description

technical field [0001] The invention relates to the construction technology of bridge anti-collision barriers, in particular to an outsourcing anti-collision barrier formwork reinforcement structure. Background technique [0002] With the development of bridges towards long-span, light weight, high strength and overall direction, the forms of bridge anti-collision barriers are also undergoing rapid changes. As the auxiliary structure of the bridge, the appearance quality of the anti-collision guardrail directly affects the overall appearance of the bridge, and it will also bring many technical problems. At present, most of the anti-collision guardrails on highway bridges are of the traditional support type, that is, the anti-collision guardrails are seated on the beam flange. [0003] In order to meet the needs of economic construction and people's aesthetic requirements, the form of anti-collision barriers of many bridges along the project is outsourced, that is, the botto...
