われる。(Prior Art) Fig. 1a is a side view of a plate joining structure using conventional joint plates, and Fig. 1b is a front view thereof. In this plate joining structure, a plate 2 to be joined is joined by two joint plates 1, a bolt 3, and a nut 4. Bonding of this type of bonded structure is carried out by the method shown in FIG. 2a or b.

る。 In the method shown in FIG. 2a, a worker 5 uses a scaffold 6 or the like to support the joint plate 1 from below or above, align the bolt holes, and join. In addition, in the method shown in Fig. b, two joint plates 1 are temporarily fastened to one joint plate 2 with bolts 3 for final tightening, and the other joint plate 2 is inserted between these joint plates 1. Insert and join. However, the method shown in Figure a has the drawback that it requires scaffolding at a high location, and the larger the joint plate 1 becomes, the heavier it becomes, requiring manpower to support it. On the other hand, the method shown in Fig. b has the disadvantage that it is not easy to insert the plate 2 to be joined between the two joint plates 1. especially,
When the cross section of the plate 2 to be joined is box-shaped, the joint plates are provided at four locations on the top, bottom, left and right, or at two locations on the left and right, making it extremely difficult to join using the method shown in FIG.

合する。 Fig. 3a is a plan view showing a joint plate according to an embodiment of the present invention and a connected plate to which this joint plate is attached;
is a plan view showing two joint plates temporarily fixed to this joint plate, and Fig. c is a plan view of a joint structure using these joint plates. As shown in Fig. a, the joint plate 9 has two corners cut out, and two auxiliary bolt holes 8 into which auxiliary bolts 10 for positioning are inserted are bored in the other corner. Auxiliary bolt holes 11 are provided in two locations corresponding to the auxiliary bolt holes 8 in the plate 2 to be connected. Of course, the joint plate 9 and the connected plate 2 have bolt holes 7 and 12 into which the bolts 3 fit.
are provided for each. The joint plate 9 and the plate 2 to be connected having such a structure are temporarily fastened together with auxiliary bolts 10 as shown in FIG. Then, after aligning the joining points as shown in Fig. c, the final tightening bolts 3 (not shown) are tightened to join both plates 2 to be joined.

様の効果が顕著である。 In this embodiment, two corners are cut out so that auxiliary bolts 10 can be attached, so that the coupling plate 9 can be attached to the plate 2 to be coupled in advance on the ground. Therefore,
Using this embodiment, it is possible to reduce the need for manpower and scaffolding when working at heights. Further, since the oblique side 15 of the other joint plate 9 can be guided between the two auxiliary bolts 10, the bolt holes 7 of the joint plate 9 and the bolt holes 12 of the plate to be connected 2 can be easily and quickly aligned. In particular, when joining materials with a box-shaped cross-sectional view, several joint plates are used at the joint, so it was difficult to join using conventional joint plates. If used, joining can be done easily and quickly.
Furthermore, even in a joined structure in which the joint plate is large, the same effect is also remarkable since there is no need to support it manually during joining.

（考案の効果）以上説明したように、本考案によれば、接合が
容易に迅速に行なえる継手板が提供できる。(Effects of the invention) As explained above, according to the invention, a joint plate that can be joined easily and quickly can be provided.
