Problems solved by technology

At the same time, when the lower bracket is installed on site, there are a large number of high-altitude welding operations, and the construction risk is extremely high. A large number of materials are piled up on site, which is not conducive to safe and civilized construction. Conducive to construction

Abstract

The invention discloses a support for a cast-in-place box girder and a construction method thereof. The support for the cast-in-place box girder is characterized by comprising a pile foundation, a cross beam, a supporting frame and a bailey frame, wherein the bailey frame is supported on the supporting frame, a supporting point is located at a web member of the bailey frame, the supporting frame is arranged on the cross beam, the cross beam is arranged at the upper end of the pile foundation, and the lower end of the pile foundation extends into the ground. The construction method comprises the steps of building of the supporting frames, construction of the pile foundations, installation of the cross beams, hoisting of the supporting frames, installation of the adjacent pile foundations and hoisting of the bailey frame. According to the support, the supporting stress point of the bailey frame can be accurately located at the position of the web member through adjustment of the pile top cross beam, and therefore the supporting effect can be achieved; compared with traditional on-site support installation and welding, installation time is saved, and the support can be disassembled for multiple times to be recycled and is more economical and reasonable; in addition, due to overall installation, welding of the supporting frame at high altitude can be avoided, and higher safety guarantee is achieved.

Description

technical field [0001] The invention relates to the construction field of a cast-in-place box girder, in particular to a support for a cast-in-place box girder and a construction method thereof. Background technique [0002] Bailey beam support is widely used in cast-in-place box girders, but the substructure of the entire support is welded on site using the same pipe piles as the foundation, which requires a lot of work at heights, difficult site welding, slow installation speed, and safe construction cannot be guaranteed. At the same time, once the foundation positioning is not accurate or the position is adjusted due to geological reasons, the top beam cannot be accurately positioned at the web member of the Bailey frame, and the bracket collapses due to the partial instability of the Bailey frame under load. Thunder beam support is used in cast-in-place concrete box girder construction system. Bailey frame is the main force-bearing member. During the construction proces...
