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.

Abstract: The present invention provides a shear reinforcement for a reinforced concrete structure which may be installed within a reinforced concrete structure after the installation of reinforcing bars during construction, in order to increase resistance against shear failure. The shear reinforcement (10) for the reinforced concrete structure includes a reinforcement bracket (20) and a connecting bar (40), wherein the reinforcement bracket (20) is disposed in a fixed number along a lengthwise direction thereof, and the connecting bar (40) is parallelly disposed in a lengthwise direction of the connecting bar (40) and fixed on each of upper anchor heads (22) of a plurality of the reinforcement brackets (20). The shear reinforcement (10) for the reinforced concrete structure according to the present invention may maximize the shear reinforcing performance of a shear reinforcement proposed by this inventor through a prior application and improve the convenience of work.
