Document Type and Number:
Japanese Patent JP7026501
Kind Code:
B2
Abstract:
To provide a joint for reinforcing bars capable of confirming the insertion depth of a reinforcing bar by visually observing the butting interval of the reinforcing bar even after the grout material is filled.SOLUTION: A joint 1 is provided with a first connecting part 11, which is formed in a cylindrical shape, and into which one reinforcing bar is inserted from the axial tip end so as to be able to pass through to be connected, and a second connecting part 12, which is formed in a cylindrical shape, and into which the other reinforcing bar is inserted from the axial tip end so as to be able to pass through to be connected. Injection holes 11d and 12d for filling grout materials between a cylindrical wall and the inserted reinforcing bar are formed in the cylindrical walls of the first and second connecting parts at intermediate positions between the axial tip end and the base end, respectively. A plurality of bridge parts 13 which are bridged in a state in which the first and second connecting parts are separated are provided between the base end part of the first connecting part and the base end part of the second connecting part at intervals in the circumferential direction of the first and second connecting parts. A gap 14 between the plurality of bridge parts 13 exposes the respective tip end parts of one reinforcing bar and the other reinforcing bar that pass through the first and second connecting parts, respectively.SELECTED DRAWING: Figure 1
