A bridge construction corbel structure fixed to concrete

Abstract

The invention relates to the technical field of bridge engineering construction, in particular to a bridge construction corbel structure fixed on concrete. The corbel structure comprises a fixed plate and a bearing plate; a reinforcing bar is arranged between the side wall of the fixed plate and the bottom surface of the bearing plate; the edge of the bearing plate is provided with a guiding groove; one end of a tensile embedded part is pre-embedded and fixed inside a concrete structure; the other end of the tensile embedded part extends to the outside of the concrete structure; the end, extending out of the concrete structure, of the tensile embedded part is provided with a guiding block; the guiding block is inserted into the inside of the guide groove from top to bottom; one end of an inner dental socket is fixedly connected with an inner dental socket connecting embedded part; the other end surface of the inner dental socket extends to the outside of the concrete structure; bolts are fastened with the inner dental socket in a threaded connection mode after penetrating through through holes. The bridge construction corbel structure fixed on the concrete is safe and reliable in structure when in use, the risk of overhead welding is avoided, disassembly and assembly are simple, the efficiency in disassembly and assembly is improved to the largest degree, and convenience is provided for maintenance and repair in the future.

Description

technical field [0001] The invention relates to the technical field of bridge engineering construction, in particular to a bridge construction corbel structure fixed on concrete. Background technique [0002] In the field of bridge construction, people have higher and higher requirements for urban bridge landscape. The corbel bracket structure is widely used in bridge structures. The corbel bracket structure used in the current bridge construction design is mostly realized by pre-embedding steel structural parts on the concrete structure and welding the corbel outside. However, its construction method involves high-altitude welding construction work, which brings risks to the safety of construction personnel and is not conducive to construction operations; moreover, the welding of corbels adds difficulty to future maintenance. [0003] Therefore it is necessary to carry out further technological innovation to the existing bridge construction corbel structure fixed on the co...
