However, in the case of a conventional jig as described above, since the fastening is performed with one central bolt, the fastening force is weak and it is difficult to align the displaced PC plate. . In addition, when the plate thickness of the PC plate changes, it is necessary to replace the bolt with a length corresponding to the plate thickness each time, which is troublesome.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to allow a PC plate or the like to be easily aligned and to be used when the thickness of the PC plate or the like changes. Another object of the present invention is to provide a matching jig that can be easily handled.

[0006]

SUMMARY OF THE INVENTION According to the present invention, a joining jig is used, for example, when joining the ends of PC plates constituting a balcony of an apartment via a caulking material, the connecting portions of the plates to be connected. A jig for aligning these plates with each other, and a plurality of horizontal members arranged in parallel along the thickness direction of the plate, and one ends of these horizontal members A positioning member that connects the parts together and abuts one surface of the plate, and a connection that connects the other end of the horizontal member and that can move along the horizontal member and be fixed to the horizontal member It is characterized by comprising a slide member and a fastening member attached to both ends of the connecting slide member and having a front end pressed against the other surface of the plate.

[0007] The horizontal member is set in the alignment direction (P
It is preferable to dispose a pair at a predetermined interval in the joining direction of the C plate or the like. It is preferable that the connecting member is fixed to the horizontal member with bolts, and a plurality of bolt holes of the horizontal member are arranged at intervals in the longitudinal direction of the horizontal member. The tightening member is composed of a bolt screwed in parallel with the plate along the thickness direction of the plate to a mounting portion provided below both ends of the connecting slide member, and a pressing plate provided at the tip of the bolt. It is preferable to face the positioning member.

[0008] As described above, the aligning jig is set at the joint between the plates from above, the positioning member is brought into contact with one side of the adjacent plate, and then each tightening member is tightened. The other end of the plate is pressed by the tip of the fastening member. Adjacent printing plates can be aligned by the positioning member, and the adjacent printing plates can be pressed by the transverse member and the tightening member provided with the joining portion interposed therebetween, so that the displaced PC plates can be easily aligned. In addition, even when the plate thickness of the PC plate or the like changes, it can be easily coped with by moving and fixing the connecting slide member.
