Precast concrete member with prefabricated plate and fixing channels

Abstract

The present invention relates to a precast concrete member using a PC member, which comprises a prefabricated plate and fixing channels, and is used as a linear member for a column which is an axial force member, as a planar member for a wall which is an axial force member, or as a linear member for a beam or a girder which is a flexural member. A preferred embodiment of the present invention provides a premade precast concrete member having a PC body formed at a predetermined length and multiple steel reinforcements embedded within the PC body along the longitudinal direction, the precast concrete member comprising: a plate assembly in which a pair of board-like plates having a pair of coupling holes formed to be penetrated at a regular interval are formed so as to be spaced apart from each other and to face each other, or two pairs of board-like plates are spaced apart from each other so as to face each other, with one end of each thereof being embedded into one or both longitudinal ends of the PC body, and the other ends thereof protruding, wherein the plate assembly comprises a connecting member of which a part embedded into the PC body of the plate is welded to one side of the steel reinforcement, and both ends are respectively bolt-coupled to the coupling holes of a pair of plates so as to connect a part embedded into the PC body of a pair of facing plates; and fixing channels which comprise a U-shaped channel having an opening formed on the top thereof and multiple anchor bodies coupled to the rear surface of the U-shaped channel, the opening of the U-shaped channel comprising a rib which is formed to be bent inwardly, wherein at least two rows of fixing channels are embedded at regular intervals into one side surface of the width direction of the PC body or into at least one pair of corresponding surfaces of the width direction of the PC body.

Description

technical field [0001] The present invention relates to a prefabricated concrete component with a prefabricated slab and an anchor channel (hereinafter referred to as a precast concrete component). On girders and beams, it is easy and simple to join column-to-column, column-to-beam, beam-to-beam and wall-to-wall using prefabricated concrete elements with prefabricated slabs and anchor channels, and because A precast concrete member with a prefabricated slab and an anchor channel that is provided with an anchor channel on the precast concrete member so that the steel bars arranged on the concrete surface can be easily combined with the precast concrete member. Background technique [0002] In the existing prefabricated concrete components, high-strength mortar is injected into the elliptical space of the prefabricated concrete component joints, and then the steel bars of the prefabricated concrete components are combined at the joints. This joining method does not immediatel...

AI Technical Summary

Problems solved by technology

[0010] The background technology cannot ensure the continuity of the cross-sectional properties of precast concrete column members and beam members and the tensile capacity of internal reinforcement, and it is difficult to combine concrete surfaces and wall reinforcement on precast concrete members
