A triangular rigid frame pier

Abstract

The invention discloses a triangular rigid frame pier. The triangular rigid frame pier comprises a cross tie beam arranged along a cross bridge direction, a pair of components, a bearing platform and the foundation, wherein the bearing platform is arranged on the top end of the foundation, the bottom end of each component is fixedly arranged on the upper surface of the bearing platform, the top ends of the components are connected with two ends of the cross tie beam; each component is an outward inclined cylinder in a vertical plane, and the bottom ends of the pair of components are staggered along a longitudinal bridge direction; the pair of the components and the cross tie beam form the triangular rigid frame. The components according to the invention are staggered along the longitudinal bridge direction to form a landscape effect that the cross bridge direction and the longitudinal bridge direction are all changed, the design is innovative and beautiful; the components and the cross tie beam form powerful triangular rigid frame system; the cross rigidity is large, the force-loading is reasonable, and the pier is safe and reliable. The triangular rigid frame pier disclosed by the invention is small in foundation scale, and can be used for saving the floor area, reducing the limit factors of the construction, and lowering the construction cost.

Description

technical field [0001] The invention relates to a bridge pier, in particular to a triangular rigid frame bridge pier. Background technique [0002] A bridge generally consists of a superstructure, a substructure and an auxiliary structure. The superstructure mainly refers to the bridge span structure and support system. The selection of the superstructure is mainly based on the comprehensive consideration of the actual use functionality, the possibility of on-site construction, and the economical implementation. However, in practical applications, the superstructure The choice is relatively simple; the substructure includes abutments, piers and foundations, and the design of the substructure is relatively diverse under the premise of meeting the force transmission requirements of the superstructure; the auxiliary structure refers to the bridge head buttress, conical slope protection , revetment, diversion works, etc. [0003] With the rapid development of bridge constructi...

AI Technical Summary

Problems solved by technology

[0005] However, the existing girder structure bridges have a relatively single structural form, which directly affects their overall landscape effect, and the base of the lower structure is large in scale and occupies a large area. The river bed is compressed to a certain extent, which is not conducive to flood control and drainage in the city; when it is used for urban flyover bridges, there are inevitable contradictions and disadvantages in solving multi-layer traffic

In addition, the large scale of the foundation of the substructure and the large footprint also lead to many construction constraints, poor construction conditions, and high project costs
