グするならば一層有利である。This concrete member joining device has the above-described configuration. In this device, the tensile force acting on the bolt joining the two members is transmitted as a compressive force to the reinforcing member located around the bolt insertion hole via the bolt head, the screw nut or the seat plate interposed, The reinforcement made of flat steel plates with a cross-section having a high cross-section has high rigidity against compression, and its length can be set to about twice the bolt diameter as shown in Fig. 2. Since the cross-sectional area of is small in the vicinity of the bolt insertion hole, it is possible to impart a large rigidity to withstand a large tensile force acting on the bolt inserted inside. The reinforcing material is fixed directly to the reinforcing bar parallel to the bolt insertion hole direction at the overhanging part on the outer side of the well, and is integrated with the reinforcing bar along the length direction of the bolt. Demonstrate. Further, since this device is not exposed to the concrete surface except for the bolts, it is advantageous against corrosion, and it is more advantageous if the inner surface of the bolt insertion hole is lined with a corrosion preventive material such as plastic.
