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.

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.
