Connecting structure of precast concrete beam and cast-in-place column and construction method thereof

Abstract

The invention discloses a connecting structure of a precast concrete beam and a cast-in-place column and a construction method thereof. The connecting structure of the precast concrete beam and the cast-in-place column comprises the cast-in-place columns, a column longitudinal reinforcement and the precast beam, wherein the column longitudinal reinforcement is arranged above the cast-in-place columns; the column longitudinal reinforcement extends into the cast-in-place columns to be fixedly connected with the cast-in-place columns; the precast beam is arranged above the cast-in-place columns;two cast-in-place columns are arranged; the two ends of the precast beam are correspondingly laminated to the two cast-in-place columns; ring buckle-shaped U-shaped reinforcements are arranged on thetwo sides of the precast beam; and the ring buckle-shaped U-shaped reinforcements extend into the precast beam to be fixedly connected with the precast beam. The problem that site assembling constructions of existing precast beam and cast-in-place column connecting structure and connecting mode are complicated during assembling connection of a prefabricated concrete structure is solved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a connection structure between a concrete prefabricated beam and a cast-in-place column and a construction method thereof. Background technique [0002] Prefabricated beams are prefabricated in factories, and then transported to the construction site to be installed and fixed according to the design requirements. Before the continuous part of the approach bridge is erected, the permanent support is installed first, and then the temporary support and the bottom mold of the cast-in-place section of the pier top are placed. After the beam body is erected, the concrete of the continuous section of the pier top is poured, and then the negative moment beam tension construction is carried out, and the temporary support is removed to form a continuous system. The cast-in-place column is a column made of reinforced concrete. The most basic load-bearing components in vario...
