Bridge transverse prestress tensioning bench

Abstract

The invention relates to a bridge transverse prestress tensioning bench. The bridge transverse prestress tensioning bench comprises a counterweight frame, a safety platform, an operation platform anda connecting truss, wherein the counterweight frame is arranged on a bridge deck; the safety operation is arranged on the side surface of the counterweight frame; the operation platform is arranged under the safety platform; and the connecting truss is arranged between the safety platform and the operation platform. Compared with the prior art, the bridge transverse prestress tensioning bench hasthe advantages that the integral stability of the bench is guaranteed placing the counterweight frame on the bridge deck and by using a counterweight block to enable construction personnel to performtransverse prestress tensioning operation by standing on the operation platform; the integral structure is simple; the dimension design is flexible; the safety coefficient is high; through rolling wheels, the bridge transverse prestress tensioning bench move on the bridge deck to be convenient for performing transverse prestress tensioning operation on different positions of the bridge; and therefore, the working efficiency is greatly enhanced.

Description

technical field [0001] The invention belongs to the technical field of bridge construction auxiliary equipment, and relates to a bridge transverse prestressed tension stand. Background technique [0002] In bridge construction, it is often necessary to configure transverse prestressed reinforcement due to force or structural requirements. When the transverse prestressed beam is stretched, workers need to install jacks on the edge of the beam. For this reason, some simple brackets are often used to hang the jacks and install them during construction. Not only is there a problem of inconvenient operation, but also the safety factor is low during construction. There is a high risk of falling. If a large-scale construction support or platform is set up under the bridge, not only the structure is complicated, the cost is high, but also it is inconvenient to move and the work efficiency is low. [0003] Therefore, it is necessary to design a transverse prestressed tensioning dev...

Problems solved by technology

When the transverse prestressed beam is stretched, workers need to install jacks on the edge of the beam. For this reason, some simple brackets are often used to hang the jacks and install them during construction. Not only is there a problem of inconvenient operation, but also the safety factor is low during construction. high risk of falling

If a large-scale construction support or platform is erected under the bridge, not only the structure is complex, the cost is high, but also the movement is inconvenient and the work efficiency is low

[0003] Therefore, it is necessary to design a transverse prestressed tensioning device to solve the problems of time-consuming, laborious and low construction efficiency in the prior art while ensuring safety.
