Abstract

A prefabricated beam wet joint diaphragm variable space operating platform and its manufacturing method, wherein the operating platform is set at the joint position of two adjacent prefabricated beams, including a bottom plate structure, an enclosure structure and a connecting member; The bottom plate structure is horizontally arranged at the bottom of the work platform; the enclosure structure is arranged along the edge of the bottom plate structure, and together with the bottom plate structure forms a box-shaped structure with a bottom and no cover; the connecting members are respectively arranged in the enclosure Both sides of the top of the protective structure; the width of the two connecting members is smaller than the width of the wet joint to be constructed; the bottom edge of the connecting member is hingedly connected with the top edge of the enclosure structure, and the top edge of each connecting member passes through The pre-embedded reinforcement gap in the wet joint to be constructed is detachably connected to the fixed member above the top surface of the prefabricated beam. The invention solves the technical problems of difficulty in setting up temporary supports at the lower part in traditional prefabricated beam joint construction, high construction cost, dangerous operation, low work efficiency and difficulty in guaranteeing construction quality.

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 ...
