Corbel support for cast-in-place concrete construction on the top of bridge pier

Abstract

The invention discloses a corbel support for cast-in-place concrete construction on the top of a bridge pier, which includes a plurality of horizontal rods arranged on the side of the large mileage and the side of the small mileage of the bridge pier, and a plurality of first horizontal rods are correspondingly arranged under the multiple horizontal rods. A diagonal brace, a plurality of second diagonal braces are arranged one by one under the plurality of first diagonal braces, and the upper ends of the plurality of first diagonal braces and the upper ends of the plurality of second diagonal braces are connected with the horizontal bar above them. The pier is provided with a plurality of first boxes corresponding to the first diagonal braces, a plurality of second boxes corresponding to the second diagonal braces and a plurality of horizontal rods corresponding to each other. The third box body, the lower end of the first diagonal strut is connected with the first box body, the lower end of the second diagonal strut is connected with the second box body, one end of the horizontal bar is connected with the third box body, and the upper end of the horizontal bar is fastened and connected Multiple prestressed tie rods. The corbel bracket overcomes the defects of high requirements on the length and quality of the weld between the horizontal bar and the third box, and difficulty in achieving it on site.

Description

technical field [0001] The invention relates to a corbel, in particular to a corbel for the construction of cast-in-place concrete on the top of a bridge pier. Background technique [0002] At present, when performing cast-in-place concrete construction on the top of the bridge pier, the existing technology uses pre-embedded steel plates on the pier body, welded with corbels composed of section steel or steel plates, as a support system for cast-in-place 0# blocks, and then laying vertical and horizontal distribution on the top Beams and formwork systems are used for cast-in-place construction. The existing technology has the following disadvantages during use: 1. Because the cantilever at both ends is too long and the weight is large, the horizontal load and bending moment borne by the corbel horizontal member will become very large. The corbels need to be specially designed to ensure that the force meets the requirements, and all the force of the corbel horizontal members ...
