Connecting method for rigid joint of steel girdle and concrete bridge pier

Abstract

The invention is a rigid connecting method of steel girder and concrete pier, a combined structural form of steel girder and reinforced concrete pier by using high-strength bolts, and the method is the rigid joint is arranged on the top of the reinforced concrete pier; the two sides of the top of the reinforced concrete pier are arranged in the vertically axial direction of a bridge with a pier-part bending moment transfer steel plate, respectively, where the distance between the two steel plates is equal to the width of the reinforced concrete pier, the tops of the two steel plates extend out of the top of the reinforced concrete pier and are connected with the two main beam-part bending moment transfer steel plates by high-strength bolts, respectively, and the two main beam-part bending moment transfer steel plates are connected with the steel girder; there are two horizontal-shear transfer steel plates, vertical to the two pier-part bending moment transfer steel plates, and arranged in the reinforced concrete pier between the two pier-part bending moment transfer steelplates, and the tops of the two horizontal-shear transfer steel plates extend out of the top of the reinforced concrete pier and are connected with the steel girder by high-strength bolts.

Description

technical field [0001] The invention relates to a combined structure of a steel girder and a concrete pier applied to a bridge, in particular to a combined structure of a steel girder and a concrete pier connected by high-strength bolts, and belongs to the technical field of civil engineering. Background technique [0002] In bridge construction, with the continuous improvement of the overall performance, span and structural form of the bridge, steel and concrete composite structure bridges have received more and more attention. Its application in engineering practice has gradually shown good social and economic effects. [0003] In the field of bridge construction, the materials used are mainly steel and concrete, so the composite structure we usually refer to mainly refers to the composite structure of steel and concrete. The biggest advantage of steel is that it has good tensile properties, while concrete has good compressive properties. If the ...

Problems solved by technology

In the traditional bridge structure form, the steel girders of the superstructure and the concrete piers of the substructure need to be provided with supports to transmit the load of the superstructure. The problem brought about by this structure is that the integrity of the bridge structure is The anti-seismic performance is relatively weak, and because of the use of bearings, it also increases the construction cost of the bridge and the maintenance management cost after completion
