Self-resetting concrete bridge pier with replaceable anti-buckling energy-consuming steel plate at bottom

Abstract

The invention relates to a self-resetting concrete bridge pier with a replaceable anti-buckling energy-consuming steel plate at the bottom, and relates to the field of fixed buildings. The self-resetting concrete bridge pier comprises a bearing platform, a replaceable component, perforated angle steel, a joint steel pipe and a pier column with an outer convex part. The outer convex part is wrapped with an upper outer wrapping perforated steel pipe. The replaceable component is detachably connected with the perforated angle steel. Anchoring steel bars are embedded in the bearing platform. The perforated angle steel is also detachably connected with the anchoring steel bars. A perforated steel plate is arranged at the joint of the perforated angle steel and the replaceable component and is used for being connected with the perforated angle steel and the replaceable component. The joint steel pipe is provided with a ball hinge type steel component and wraps the bottom of the pier column. A concave steel component is arranged on the surface of the bearing platform. The joint steel pipe is placed on the concave steel component. The scheme of the self-resetting concrete bridge pier solves the technical problem that a bridge pier is damaged after an earthquake but is difficult to repair and is suitable for bridge pier construction.

Description

technical field [0001] The invention relates to the field of fixed buildings, in particular to a self-resetting concrete pier with a replaceable anti-buckling energy-dissipating steel plate at the bottom. Background technique [0002] With the continuous development of modern basic theories and the application of new technologies and materials, people are looking forward to new bridge structures and putting forward new requirements for bridge quality. The construction of bridges has brought great convenience to economic development and traffic travel. Among them, bridge piers, as components bearing the upper load of bridge structures, play a pivotal role. Multiple earthquake damage investigations have shown that the failure mode of bridge piers mainly occurs at the base of columns and other connecting parts. [0003] In order to reduce the loss caused by bridge damage, such as the loss caused by earthquakes, there are currently two methods for seismic design of bridges, nam...

Problems solved by technology

[0007] The beneficial effects of the present invention are: detachably connect the part of the pier used for energy consumption, and the part that is most likely to be lost is used as a replaceable part. When the pier needs to be repaired, only the replaceable part or other detachable parts need to be replaced. Thereby reducing the difficulty of replacing replaceable parts and solving the technical problem of how to quickly replace damaged parts;
