Document Type and Number:
WIPO Patent Application WO/2020/138354
Kind Code:
A1
Abstract:
The purpose of the present invention is to suppress both lateral sides at each entry of fitting recesses of a foundation joint from expanding in a direction away from each other when tensile force of a reinforcing steel bar is being exerted, and, even when expanded, to prevent grout and concrete at portions adjacent to the lateral sides from being subjected to deforming pressure. A foundation joint 1 is provided with: a first fitting recess 11 into which an end portion of a reinforcing steel bar 2 and a protrusion 21 provided at a distal end side of the reinforcing steel bar 2 are fitted; a second fitting recess 12 into which an end portion of another reinforcing steel bar 2 and a protrusion 21 provided at a distal end side of the reinforcing steel bar 2 are fitted; and a reinforcing rib portion 13 positioned between the first fitting recess 11 and the second fitting recess 12.
