Document Type and Number:
Japanese Patent JP2023073752
Kind Code:
A
Abstract:
To improve productivity such as labor saving, manpower saving, and a shorter construction period by maximizing the advantage of adopting a half-precast method when a half-precast concrete member is manufactured.SOLUTION: A method for constructing a half-precast concrete member composed of a precast concrete member and a cast-in-place concrete member comprises: a step of manufacturing a precast concrete member in a state where a looped reinforcement is projected from the surface off-site; a step of manufacturing a reinforcement unit off-site; a step of installing the precast concrete member at a construction site; a step of mounting the reinforcement unit on the precast concrete member; and a step of installing cast-in-place concrete so as to bury the reinforcement unit in the surface of the precast concrete member. The reinforcement unit is provided with connection means for connection with the looped reinforcement projected from the precast concrete member.SELECTED DRAWING: Figure 1
