Japanese Patent JP2019157488
Kind Code:
A
Abstract:
To provide a junction structure for a half PCa earthquake-resisting wall, which provides high workability and facilitates securing of a space for a joint.SOLUTION: The walls (2, 4, 5) of an earthquake-resisting wall have cast-in-place parts (7a-7c) made of cast-in-place concrete cast with pairs of PCa members (6a-6f) in a half PCa structure. A concrete part (8) of each PCa member has a flat-plate body (9) and a plurality of projections (10) that are provided to the backside of the body so as to extend in a longitudinal direction. A longitudinal reinforcement (11) is buried in each projection except the upper end thereof, and the upper end projects from the projection. A lateral reinforcement (12) is buried in the body. The upper end of the longitudinal reinforcement of a lower floor is inserted into a cast-in-place part of an upper floor so as to be received in a recess formed between the two adjacent projections of the upper floor. Thus, the upper end of the longitudinal reinforcement of the lower floor and the lower end of the longitudinal reinforcement of the upper floor form a lap joint.SELECTED DRAWING: Figure 1
