Fastener connecting structure for cantilever box beam triangle brackets

Abstract

The invention provides a fastener connecting structure for cantilever box beam triangle brackets, and relates to the technical field of bridge construction. The fastener connecting structure comprises a pier, wherein triangle brackets are symmetrically arranged on the two sides of the pier; embedded parts are arranged in the pier; the triangle brackets are fixedly mounted on the side walls of the pier through the embedded parts; the triangle brackets symmetrically on the two sides of the pier are connected through an anchoring system; the embedded parts and the triangle brackets are connected through steel plate fastener pins; the triangle brackets on the same side of the pier are connected into a whole body through a transverse connecting system. The load is transferred by utilizing the steel plate fastener pins, so that the shear capacity is improved, and the influences that concrete is heated and fractured and steel plates are deformed caused by direct welding and thermal cutting on the embedded parts are completely eradicated.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a cantilevered box girder triangular bracket fastener connection structure. Background technique [0002] Prestressed reinforced concrete continuous box girder is a common superstructure form of bridges, and the hanging basket construction method is often used, such as figure 1 As shown, the 0# block at the top of the pier is a working platform assembled with hanging baskets, and the load-bearing system of the overhanging part of the pier top can adopt a triangular bracket structure. At present, the shear resistance of the existing load-bearing system is poor. The brackets of the load-bearing system are directly welded to the embedded parts. During the construction process, the concrete will be cracked by heat and the steel plate will be deformed. The construction safety is low and the construction quality is not easy to control.

AI Technical Summary

Problems solved by technology

At present, the shear resistance of the existing load-bearing system is poor. The bracket of the load-bearing system is directly welded on the embedded parts. During the construction process, the concrete will be cracked by heat and the steel plate will be deformed. The construction safety is low and the construction quality is difficult to control.
