Prefabricated pier and bearing platform connected structure and butt joint construction method thereof

Abstract

The invention discloses a prefabricated pier and bearing platform connected structure. The prefabricated pier and bearing platform connected structure is characterized in that a bottom connecting section of a pier body of the pier is connected with the top surface of the bearing platform to be formed into a whole. The bottom connecting section of the pier body and the bearing platform can be poured together; or a prefabricated section member can be inserted into the bearing platform; shear keys which are correspondingly matched with each other are arranged at a connecting position of the pier body bottom connecting section and the pier body prefabricated section. The prefabricated pier and bearing platform connected structure and a butt joint construction method thereof have the advantages of effectively reducing bending moment at seaming positions, improving stained condition of seams and improving durability of the seams due to the fact that seaming cross sections are moved upward from the pier bottom through a butt joint structure; strengthening shear resistant performance of the seams and being convenient to construct due to the fact that the shear keys with corresponding concave and convex surfaces are arranged on the seams; enabling force bearing of the pier and the bearing platform connection to be reliable, being convenient to construct, simple to operate and easy to control, effectively reducing workloads for field welding and concrete pouring and enabling construction process to be speeded up.

Description

technical field [0001] The invention relates to the technical field of civil engineering design, in particular to a connection structure between a prefabricated bridge pier and a cap and a butt joint construction method thereof. Background technique [0002] At present, the substructures of urban bridges commonly used in my country are all cast-in-place construction methods, which not only prolong the construction period of bridges, but also bring more adverse effects on the urban environment. With the continuous advancement of my country's large-scale urban construction process at this stage, energy conservation, environmental protection, and low carbon have gradually become the theme of my country's economic development. [0003] One of the main challenges facing the current design of urban bridge structures is that in addition to the safety and durability of the bridge structure, owners and residents also require rapid construction to reduce interference with surrounding ...
