A kind of cushioning and protecting component around pier columns used in bridge construction

Abstract

The invention discloses a pier column peripheral buffer protection assembly for bridge construction, and relates to the technical field of bridge protection. The invention includes a pier column body; a protective mechanism is movably installed on the side of the pier column body; the protective mechanism includes two anti-collision assemblies with the same structure and connected to each other through connecting pieces; the anti-collision assembly includes an upper hoop, a middle hoop and a lower hoop. Hoop; the limit frame is hinged on the side of the lower hoop; one surface of the limit frame is hinged with two symmetrically arranged first compressive and tensile members and two symmetrically arranged second compressive and tensile members; two first compressive and tensile members are hinged. The ends of the tension parts far away from the limit frame are hinged with the middle hoop; the ends of the two second compression and tensile parts far away from the limit frame are hinged with the upper hoop. Through the design of the protection mechanism and the anti-collision component, the invention adds a buffer protection device on the basis of the traditional bridge pier column, and then effectively improves the anti-collision performance of the bridge pier column through the layout of the buffer protection device.

Description

technical field [0001] The invention belongs to the technical field of bridge protection, and in particular relates to a buffer protection component around pier columns used in bridge construction. Background technique [0002] The pier column is the lower load-bearing object used to carry the upper structure in civil engineering. The cross-section of the pier column is mostly circular, and there are also heterogeneous pier columns such as oval, square, curved, and parabolic. It is an important part of highway bridges, railway bridges, sidewalks and other bridges, overpasses, ramp bridges, flyovers and other projects. [0003] Most of the existing piers are exposed. In the event of accidental traffic accidents, they are easily impacted by vehicles. In severe cases, the vehicles will be scrapped, and the structural stability of the piers will also be damaged. Contents of the invention [0004] The purpose of the present invention is to provide a pier column peripheral buff...
