Steel K brace-hollow concrete column pier

Abstract

The invention discloses a steel K brace-hollow concrete column pier for effectively shortening a construction period of a bridge and reducing bridge construction investment. The steel K brace-hollow concrete column pier comprises a left hollow concrete pier stud, a right hollow concrete pier stud, a stud roof beam, and a steel K brace formed by a steel K brace cross bar and a steel K brace sway rod; pier body force transfer connecting components are pre-buried into the left hollow concrete pier stud and the right hollow concrete pier stud along a longitudinal interval; a roof beam force transfer connecting component is pre-buried into the middle of the stud roof beam; two ends of the steel K brace cross rod are fixedly connected with the pier body force transfer connecting components and the top end is fixedly connected with the roof beam force transfer connecting component; and two ends of the stud roof beam and the left hollow concrete pier stud and the right hollow concrete pier stud are solidified into a whole separately.

Description

technical field [0001] The invention relates to bridge engineering, in particular to a steel K brace-hollow concrete column bridge pier. Background technique [0002] In U-shaped or V-shaped valley areas with good foundation conditions, the upward-supported arch bridge has been widely used in the construction of mountainous railways and highways due to its large building height, easy control of the connection elevation at both ends, and coordination with mountainous terrain. According to the size of the span, concrete, steel pipe concrete, and steel truss structure arch rings are generally used; in order to meet the strength and rigidity requirements, reinforced concrete rigid frame piers are generally used for the columns on the arch. There are also arch piers with all-steel structures on highway bridges, but It is rarely used on railways that require high pier stiffness, and the cost of all-steel structures is relatively high. [0003] Ordinary reinforced concrete piers a...

AI Technical Summary

Problems solved by technology

The pier columns are connected by a horizontal connection system. Due to the small size of the cross section, the horizontal connection system has the problems of difficult binding of steel bars and difficult control of the quality of the concrete. In addition, the method of erecting a full hall on the arch is often used for construction, which is difficult to construct and has a relatively long construction period.
