Rack for binding prefabricated box girder top plate reinforcement cage

Abstract

The invention relates to a rack for binding a prefabricated box girder top plate reinforcement cage; the rack comprises at least two support units, two parallel reinforcement limiting components, at least two parallel first reinforcement supporting components and at least one second reinforcement supporting component. Each support unit is of a T-shaped structure, all the support units are arranged side by side, the projections of the support units coincide, and the two reinforcement limiting components are connected to the two transverse ends of each support unit respectively, so that an elongated T-shaped structure is formed. Each first reinforcement supporting component is located between the two reinforcement limiting components and is parallel to the reinforcement limiting components, each first reinforcement supporting component is connected to the support unit, each first reinforcement supporting component is provided with a plurality of steel bar positioning grooves distributed according to preset intervals, and all the steel bar positioning grooves are aligned in the transverse direction and the longitudinal direction; the groove bottom of each steel bar positioning groove, the bottom face of the reinforcement limiting component and the second reinforcement supporting component are located on the same horizontal plane.

Description

technical field [0001] The invention belongs to the technical field of roof reinforcement skeleton binding, and in particular relates to a bench for binding a prefabricated box girder roof reinforcement skeleton. Background technique [0002] In the construction of infrastructure such as highways and bridges, cement reinforcement is a commonly used and extremely important method to ensure the strength of concrete structures. In the bridge structure, due to the relatively large load that the bridge body has to bear, it is necessary to arrange a large number of steel bars in the load-bearing structure to ensure the structural strength of the reinforced concrete. As a rule, a reinforced skeleton is formed by binding. [0003] Generally, the roof reinforcement skeleton is bound directly above the pier base, and then concrete is poured. However, due to the large span between the piers, it is extremely inconvenient to operate. In addition, the reasons for high-altitude operation...

Problems solved by technology

[0003] Generally, the roof reinforcement skeleton is tied directly above the base of the bridge pier, followed by concrete pouring. However, due to the large span between the bridge piers, it is extremely inconvenient to operate, and during the operation, due to the lack of supporting structures below, And the reasons for high-altitude operations are likely to cause uneven spacing of steel bars, inaccurate positioning, and easier deformation after binding, which greatly slows down the progress of construction
