Precast beam wet joint diaphragm plate variable space operation platform and manufacturing method thereof

Abstract

The invention provides a precast beam wet joint diaphragm plate variable space operation platform and a manufacturing method of the precast beam wet joint diaphragm plate variable space operation platform. The operation platform is arranged in the joint position of two adjacent precast beams and comprises a bottom board structure, an enclosure structure and connecting components. The bottom boardstructure is horizontally arranged at the bottom of the operation platform. The enclosure structure is arranged along the edge of the bottom board structure, and the enclosure structure and the bottomboard structure jointly define a box structure with a bottom and without a cover. The connecting components are arranged on the two sides of the top of the enclosure structure. The width of the two connecting components is smaller than the width of a to-be-constructed wet joint. The bottom edges of the connecting components are hinged to the top edges of the enclosure structure. The top edge of each connecting component penetrates through an embedded reinforcing steel bar gap in the to-be-constructed wet joint to be detachably connected to a fixing component above the top face of the corresponding precast beam. The operation platform solves the technical problems that in traditional precast beam joint construction, a lower temporary support is difficult to erect, construction cost is high, operation is dangerous, work efficiency is low, and the construction quality is hard to guarantee.

Description

technical field [0001] The invention relates to the technical field of bridge narrow space construction, in particular to a prefabricated beam wet joint diaphragm variable space operating platform and a manufacturing method thereof. Background technique [0002] During the construction of the bridge, the turbulent water under the bridge brought great difficulties to the construction. It is difficult to obtain a reliable foundation for the temporary support of the lower part. The temporary support of the lower part often requires a lot of manpower and financial resources. At the same time, it is a huge project for the project. As a source of danger, if we can find a load-bearing structure on the upper part, it is not only safe and economical, but also very convenient, and there is no need to consider the turbulent water in the lower part. This top-down type will be an industrial revolution in the field of bridge construction. [0003] The prefabricated beam of the bridge is ...
