A construction method for horizontal prefabricated components of prefabricated concrete structures

Abstract

The invention discloses a construction method for fabricated concrete structure horizontal prefabricated components. The construction method comprises the steps that the positions of column main reinforcements are positioned, and column stirrups are placed on the positions of the column main reinforcements; supporting framed bents of the horizontal prefabricated components are erected on the periphery of a cast-in-situ frame column; the horizontal prefabricated components are hoisted on the supporting framed bents, and a core zone is reserved; core zone stirrups are installed in the core zone; the column main reinforcements of the cast-in-situ frame column are installed on the positions of the column main reinforcements, the column stirrups are fixed to the column main reinforcements according to a regulated separation distance, and the core zone stirrups are fixed to the column main reinforcements; a column formwork of the cast-in-situ frame column is installed; and concrete is poured. According to the construction method for the fabricated concrete structure horizontal prefabricated components, the installation order of the column main reinforcements, the column stirrups, the horizontal prefabricated components and the core zone stirrups is reasonably adjusted, the horizontal prefabricated components and the core zone stirrups are installed firstly and then the column main reinforcements and the column stirrups are installed so that the problem that installation of the post-mounted horizontal prefabricated components with the column main reinforcements and the core zone stirrups is not convenient can be effectively solved, and the installation efficiency of the fabricated concrete structure horizontal prefabricated components is improved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method for a horizontal prefabricated component of an assembled concrete structure. Background technique [0002] The current existing construction methods for horizontal prefabricated components of prefabricated concrete structures are: binding column main reinforcement and stirrups, erecting horizontal component support frames, installing prefabricated beams, installing prefabricated slabs, binding laminated layer reinforcement, and pouring concrete. [0003] There are following problems in the above-mentioned installation method of this prefabricated building: [0004] 1) The number of column main reinforcement is large and dense, and the prefabricated beam reinforcement is easy to collide with the column main reinforcement, which increases the difficulty of positioning and placement, and affects the efficiency of installation; [0005] 2) The installation ...

AI Technical Summary

Problems solved by technology

[0004] 1) The number of column main reinforcement is large and dense, and the prefabricated beam reinforcement is easy to collide with the column main reinforcement, which increases the difficulty of positioning and placement, and affects the efficiency of installation;

[0005] 2) The installation of stirrups in the beam-column core area is difficult: if the stirrups in the beam-column core area are installed first, the prefabricated beam cannot be hoisted; if the prefabricated beam is hoisted first, the stirrups in the core area are inconvenient to install;

[0006] 3) When the column reinforcement is installed, it is necessary to set up an operation platform for binding the reinforcement, which increases certain safety hazards
