Anti-overturning bridge pier structure

Abstract

The invention belongs to the field of bridge piers, and particularly relates to an anti-overturning bridge pier structure. A mounting plate is fixedly mounted at the top of a stand column on a base; abridge is fixedly mounted at the top of a support in the center of the top of the mounting plate; the top of the mounting plate is fixedly provided with two pieces of symmetrically-arranged I-shapedsteel, and the top of each piece of the I-shaped steel is fixedly mounted with the bottom of the bridge; the two pieces of I-shaped steel are respectively positioned on two sides of the support; the top of the mounting plate is fixedly provided with two pieces of arc-shaped steel which are symmetrically arranged; shearing force assemblies are fixedly mounted at the top of the two pieces of arc-shaped steel; the top of each of the two shearing force assemblies is fixedly mounted with the bottom of the bridge; anti-overturning bases are fixedly mounted at two sides of the stand column; two symmetrically-arranged inclined supports are movably mounted at the top of each anti-overturning base; and the top parts of the two inclined supports located on the same side are fixedly mounted with the bottom of the mounting plate. The problems that the connection tightness of the bridge and the mounting plate is not high, the connection strength of the mounting plate and the stand column is low, andconsequently the anti-overturning capacity of the bridge is poor are solved.

Description

technical field [0001] The invention belongs to the field of bridge piers and relates to an anti-overturning bridge pier structure. Background technique [0002] Curved bridges such as urban overpasses and high-speed ramps mostly adopt the single-column cast-in-place continuous box girder structure. The internal structure of this type of bridge has the advantages of reducing land occupation, increasing visual field and beautiful bridge. [0003] Notification number is that the authorized document of CN106120539B discloses a kind of single column pier bridge anti-overturning structure, solves the problem that single column bridge easily overturns. It includes auxiliary support blocks installed on both sides of the pier column, self-aligning support installed between the pier column and the bottom of the bridge girder, and an anti-fall device installed between the auxiliary support block and the bottom of the bridge girder, among which the self-aligning support The seat inclu...

Problems solved by technology

[0004] In view of this, the present invention provides an anti-overturning bridge pier structure in order to solve the problem that the connection tightness between the bridge and the mounting plate is not high, and the connection strength between the mounting plate and the column is low, resulting in poor anti-overturning ability of the bridge
