Bridge structure connecting joint and construction method

Abstract

The invention relates to a bridge structure connecting joint and a construction method. The bridge structure connecting joint comprises a movable supporting seat, a peripheral connecting part and a fixed connecting body; the movable supporting seat is disposed between a bearing structure and a bent cap structure and is used for movably supporting a bent cap body; the peripheral connecting part isarranged around the bearing structure and the bent cap structure and used for connecting the bearing structure and the bent cap structure in the circumferential direction; and the fixed connecting body is arranged around the movable supporting seat, is arranged between the bearing structure and the bent cap body in a filling mode, and is used for fixedly connecting the bearing structure with the bent cap body. According to the connecting mode of the bridge structure connecting joint, the structure is good in stress, and a stand column cannot be damaged when impact loads and bending moments areapplied to the bearing structure; the peripheral connecting part can prevent the bearing structure and the bent cap structure from horizontally and relatively sliding under the accidental condition,and safety accidents caused by position deviation are avoided.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a connection node of a bridge structure and a construction method. Background technique [0002] For urban viaduct projects with heavy ground traffic, the traditional construction method of pouring concrete on site is directly carried out on-site at the bridge site, which will block traffic for a long time and generate large construction pollution, which cannot meet the current requirements. Ecological construction and environmental protection requirements; and repeated configuration of construction equipment and auxiliary facilities, resulting in large resource and energy consumption, waste of financial and material resources and other problems. [0003] Different from the traditional cast-in-place construction method, most of the work is completed in the factory by adopting the "fabricated bridge construction method" of factory prefabrication and on-site assembly. With the ...

AI Technical Summary

Problems solved by technology

[0006] Based on this, it is necessary to provide a bridge structure connection node and construction method for the problem that the traditional connection method of steel cap beam and column has poor structural stress, and the impact load and bending moment applied to the column may easily cause damage to the column.
