Assembly type structure with concrete-filled-steel-tubular radial gate support and pier

Abstract

The invention discloses an assembly type structure with a concrete-filled-steel-tubular radial gate support and a pier. The assembly type structure comprises a concrete pier and a radial gate supportconnected with the pier, and foundation bolts are arranged on the radial gate support; the structure is characterized in that the radial gate support is a concrete-filled-steel-tubular member formed by filling concrete in a steel tube with a polygonal cross section, the part, connected with the pier, of the radial gate support is cast to be integrated with the pier through the concrete, and the radial gate support is partially buried inside the pier; a plurality of radiation steel bars arranged outside the part, buried inside the pier, of the radial gate support are connected with the piers, and supporting legs are fixedly connected with the bottom of the part, buried inside the pier, of the radial gate support; and the supporting legs is fixedly connected with anchor plates pre-buried onthe pier. The structure is simple, the connection strength between the support and the pier is high, the support can be adjusted in the construction process, the accuracy of the installation positionis high, the construction difficulty is low, the problems of a conventional structure with a concrete corbel type support and a pier are solved, and the structure can be widely applied to water gate engineering.

Description

technical field [0001] The invention relates to an assembled steel pipe concrete arc door support gate pier structure, which belongs to the technical field of water conservancy facilities. Background technique [0002] In the sluice engineering, the arc door support is a short cantilever member, and its function is to transfer the load to the main structure pier. In the prior art, reinforced concrete corbel-type bearings and gate pier structures are usually used between the arc door support and the gate pier. This structure has the following outstanding problems: ①The connection between the support and the gate pier and the local tension area of ​​the gate pier The crack resistance of concrete is poor; ②The corbel of the arc door support is large in size, heavy in structure, poor in seismic performance, and affects flood discharge; The reinforcement mesh of the gate pier is interwoven with the reinforcement mesh of the gate pier, the construction is difficult, and the quali...
