The present invention will be described below with reference to the illustrated embodiments. A is a beam, and a reinforcing bar insertion hole 1 is penetrated in the axial direction of the beam, and the deformed reinforcing bar constituting the above-mentioned joining rod, the reinforcing bar 2 made of a screw rod reinforcing bar and the like, and a grip joint at the tip of the reinforcing bar Alternatively, a sleeve 3 having an internal thread on the inner peripheral surface thereof, which is fixed by means such as screwing, is inserted and incorporated.

Further, columns B and B'arranged at predetermined intervals.
The insertion hole 1 is provided so as to straddle the beam A ′ in contact with each of the columns, and the reinforcing bar 2 having the sleeve 3 fixed to the tip thereof is inserted and incorporated into the insertion hole 1 in the same manner as described above. Then, as shown in FIG. 1, the beam A is hung between the opposing columns B and B ', and as shown by an arrow in FIG. Using the gap t generated between the other pillar B and the other pillar B, the bolts 4 constituting the above-mentioned screw joining member are inserted into the respective reinforcing bar insertion holes 1 of the other pillar B and the beam A facing each other and incorporated. The beam A is crimped to the other pillar B by screwing and tightening between the tip sleeves 3 of the reinforcing bars 2.

As a result, as shown in FIG. 3, a gap t is formed between the beam A and the one pillar B'and the beam A. By utilizing this gap t, the bolt 4 is interposed in the same manner as described above. It is screwed and tightened between the tip sleeves 3 of the reinforcing bars 2 inserted into the reinforcing bar insertion holes 1 of the one pillar B'and the beam A. As described above, when the joining of the reinforcing bars inserted in the reinforcing bar insertion holes 1 of the adjacent columns and beams is completed, the water blocking sealing material 5 is installed, and the water repellent sealing material 5 is provided in each of the reinforcing bar insertion holes 1 to the beam A An adhesive such as an epoxy resin is filled from the inlet 6 to integrate the insertion hole 1, the bolt 4, the pillars B and B ′, and the beam A.

[0010]

As described above, according to the present invention, the inner peripheral female screw portion is provided at the tip end of the insertion hole provided over the columns arranged at predetermined intervals and the beams in contact with the columns. Insert the joint rod to which the sleeve is fixed, and insert the joint rod to which the sleeve with the inner peripheral female thread at the tip is fixed between the opposing columns into the insertion hole that penetrates in the axial direction. The beam is hung down, and the beam is biased so that it touches one of the opposing columns, thus creating a gap between the other of the columns facing the beam and the joining screw material in the gap. The other column and the beam are coupled by being screwed and tightened to the tip sleeves of the respective connecting rods inserted and inserted into the other column and the beam.

As a result, the gap between the beam and the one column is used to connect the one column and the beam through the joining screw material in the same manner as described above.
