Building formwork for highway bridges

Abstract

The invention provides a building template for a highway bridge, and solves the problem that in the using process, an existing building template cannot have both intensity and rigidity and also cannot have both low use cost and great turnover times. The building template for the highway bridge comprises a square wood board; one end face of the wood board is of a plane structure; convex ribs are formed at intervals on the other end face; all the convex ribs are arranged into a rectangular array in the same direction; a wrapping part made of lightweight metal is arranged at the plane structure; the wrapping part is provided with a transition part beyond an interface of the wood board along the edge of the wood board; the transition part is provided with a fastening part; the fastening part is provided with a bending part matched with the wood board; the transition part is also provided with an abutting part; the abutting part comprises a first abutting interface extending outwards at an angle of 45 degrees with the inner surface of the wrapping part and a second abutting interface extending outwards at an angle of 90 degrees with the first abutting interface. According to the building template provided by the invention, the turnover times of the template in the using process can be ensured, and turnover and use cost of the template is greatly reduced.

Description

technical field [0001] The invention relates to the field of concrete pouring for large buildings or highway bridges, in particular to building templates for highway bridges. Background technique [0002] In recent years, the domestic construction industry has developed vigorously, among which the reinforced concrete structure project has the fastest development. In the reinforced concrete structure, the cost of the formwork project is the highest, accounting for about 25% of the total cost of the entire reinforced concrete, and its labor accounted for 1% of the reinforced concrete structure. It takes about 35% of the total labor of the concrete structure, and its construction period accounts for 50% to 60% of the total construction period of the project. Therefore, if the cost of the formwork project can be controlled during the construction process, it will be of great importance to the cost control and economic benefits of the entire project. important meaning.
