(Problems to be solved by the invention) However, in the above-mentioned conventional technique, it is necessary to sequentially rotate the three anchor rebars 9U, 9D, 9D little by little so that the tensioning forces thereof become substantially equal. However, the work itself was very skilled and time consuming.
That is, it is relatively easy to adjust up to two lines, but when adjusting the third line, the tension force is unavoidably biased and it becomes necessary to readjust all three lines from the beginning. In addition, it is difficult to get hands in the formwork of the segment 5 where the reinforcing bars are vertically and horizontally converging. It is very difficult to rotate and adjust the three anchor reinforcing bars 9U, 9D and 9D. Was there.

In the joint fitting 1 configured as described above, when the pair of joint fittings 1 and 1 are faced to each other on the rear surface side so as to be connected by the anchor rebars 9, as shown in FIGS. Since the side receiving portion 7D is symmetrical with respect to the center line CL of the joint plate 2, the positions thereof face each other in both joint fittings 1 and 1, and the upper receiving portion 7U conversely becomes staggered and cannot face each other. , Lower receiving part
Connect the fitting 1 with only two lower anchor rebars 9D, 9D that are screwed to 7D, and other upper anchor rebars 9U, 9U, 9U, 9
U can be simply screwed to either one of the fittings 1. Therefore, in the formwork of segment 5,
It is only the lower anchor rebars 9D and 9D that come to the deeper position of the mold when inserting into the formwork that adjusts the bracing force by rotating in a certain direction, and the upper anchor rebar 9U that should come to a shallower position. , 9U, 9U, 9U can be installed one by one after the adjustment, so the fitting 1 can be easily set even in the formwork where the reinforcing bars are converging vertically and horizontally. The property is improved.

Moreover, since the positions of the upper receiving portions 7U do not match each other, the upper anchor rebars 9U, 9U, 9U, 9U screwed to the upper receiving portions 7U do not interfere with each other, and their lengths (lap lengths) are determined by the other side. Since it can be extended to the vicinity of the fitting metal fitting 1 of each, the adhesion strength of each anchor rebar 9U, 9U, 9U, 9U to concrete is sufficiently obtained,
There is no need to fall out of

Further, in the lower receiving portion 7D, since the threading directions of the lower screw holes 8D are opposite to each other on the left and right, when facing the back side of exactly the same pair of fittings 1 and 1, they face each other. Since the corresponding lower screw holes 8D, 8D also have opposite thread cutting directions, the type of fitting metal fitting 1 can be used to make the joint fitting 1 separate (or approach) when the anchor rebar 9D rotates in a certain direction. Therefore, only one type of mold is required, which is very economical and does not cause unnecessary confusion at the work site.

The embodiment according to the present invention is not limited to the above, and for example, only one upper receiving portion 7U may be provided.
In this case, considering the positional balance with the lower receiving portion 7D to some extent, it is desirable to provide it on the upper side,
It is preferably provided at least at the same position or above the bolt insertion hole 2a on the outer diameter side of the tunnel. This also applies to the case where there are two upper receiving portions 7U as in the present embodiment.

(Effect of the Invention) According to the present invention, when the rear sides of the pair of joint fittings 1 and 1 are opposed to each other, the lower receiving portion 7D has a corresponding position, and conversely, the upper receiving portion 7U. Since they are mutually staggered and do not correspond to each other, when inserting and setting a pair of joint metal fittings 1 and 1 connected by anchor rebar 9 in the formwork, it is important to adjust the tension force of the formwork. Only the two anchor rebars 9 related to the lower receiving part 7D that come to a deeper position are required, and the anchor rebar 9 related to the upper receiving part 7U that comes to a shallower position of the formwork is the above-mentioned sequential fitting metal fittings 1,1. It is only necessary to attach it to one of the above, and the work becomes very simple. Further, at this time, since the upper receiving portions 7U are staggered, the anchor rebars 9 attached to them are also staggered and do not interfere with each other, so that the length can be set to a sufficient wrap length. Adhesion with concrete can be sufficiently obtained.
