構成であつてもよい。 In FIG. 1, a joining metal fitting 1 has one side portion formed into a plate shape, the planar shape of which is, for example, a plucked shape, and a groove surface 2 is provided at the tip. The other side of the joining hardware 1 is a rod-shaped attachment portion 3, and a threaded portion is provided on the outer periphery of this attachment portion. This attachment part can be screwed into the opening at the end of a threaded hole 5a of the joint pipe 5 which is fitted and crimped onto the end of the reinforcing bar 4. A nut 6 is attached to the mounting portion 3 in order to fix this screw connection. The means of connecting the joining hardware 1 and the reinforcing bars 4 does not necessarily need to be a joint pipe,
When the diameter of the reinforcing bar is large, the fitting part 3 of the joining hardware may be directly screwed into a screw hole drilled at the tip of the reinforcing bar.

している。 Next, a connection structure between a PC beam and a column steel frame using the joint hardware 1 of the present invention will be explained based on FIGS. 2 and 3. Four main beam reinforcements (only the beam main reinforcement 4a is shown in the drawing) are arranged at the inner lower part of the PC beam 7, and four main beam reinforcements 4b, 4c,
4d and 4e are arranged, and joining metal fittings 1 are attached to the tips of the central beam main reinforcements 4a, 4c, and 4d among the upper and lower beam main reinforcements via joint pipes 5. Then, the tip of the joint metal fitting 1 is brought into contact with the flange 8a of the column steel frame 8, and the groove surface 2 is welded to the flange.

接を行う。 A method for joining the joint hardware 1 during construction of this joint will be described. After joining the joint steel frame 9 of the PC beam 7 and the gusset plate 10 of the column steel frame 8 with bolts 11 and temporarily fixing the PC beam and the column steel frame,
Turn the joint hardware 1 attached to the lower beam main reinforcement 4a as appropriate, and when the gap between the groove surface 2 and the flange 8a of the column steel frame is determined to a predetermined value, tighten the nut 6 to fix the joint hardware. After fixing, weld the groove.
