[Effect]

Fig. 1 shows the function of the receiving metal fitting of the first embodiment of the present invention.
This will be explained based on FIG. As shown in FIGS. 1 and 2, the receiving fitting of the first embodiment is particularly suitable for constructing the outer enclosure of the interlock-shaped building board 9. This will be explained using the construction of the outer enclosure as an example. First, the receiving fitting main body A is fixed onto a structural member 8 such as a purlin or a rim, and the mounting bottom portion 7b of the hanger 7 is attached to the mounting hole 4a of the base plate 4 of the upper fitting B with bolts or the like.

Then, the top surface part 9b of the cross-shaped construction board 9 is placed on the horizontal piece 4c of the upper metal fitting B of the receiving metal fitting, the lower part 9c is locked to the locking part 7a of the hanger 7, and then the adjacent The upper part 9d of the cuff-shaped construction board 9 is fastened to the locking part 7a of the hanger 7, and this process is repeated one after another to construct the outer enclosure.

Next, the operation of the receiving metal fitting according to the second embodiment of the present invention will be explained based on FIG. 7. The brackets of these two embodiments are particularly suitable for constructing the outer envelope of the folded construction board 10, and will be explained using the construction of the outer envelope of the folded construction board 10 as an example. . First, the bracket body A
is fixed on a structural member 8 such as a purlin or a rim, and a chevron portion 10a on one side of the folded construction board 10 is placed on the flange 5a of the screw rod 5 of the upper metal fitting B or on the gate-shaped metal fitting 6. The chevron portion 10a on the other side of the adjacent folded construction board 10 is placed on top of this, and the threaded rod 5 of the upper metal fitting B is inserted into this overlapping portion, screwed with a nut, and then removed. This involves constructing an enclosure.

[Effect of idea]

In the present invention, rising pieces 2b, 2b are provided on both sides of the top surface 2 of the substantially mountain-shaped receiving fitting main body A,
Through-holes 2c, 2c are bored in these rising pieces 2b, 2b, and the upper metal fitting B is loosely inserted into these through-holes 2c, 2c, so that the upper metal fitting B can be made to be a receiving metal fitting that can freely slide on the receiving metal body A. By using this for constructing the outer envelope of the folded or folded construction board, firstly, the outside temperature of the outer envelope of the folded or folded construction board 9 or the folded construction board 10 can be reduced. It can respond well to the thermal expansion and contraction in the longitudinal direction due to changes in
Thirdly, the structure is extremely simple, has excellent workability, and can be provided at a relatively low price.

To explain these effects in detail, the rising pieces 2b provided on both side edges of the top surface portion 2 of the receiving fitting main body A of the present invention,
Since the upper metal fitting B is loosely inserted into the through-holes 2c, 2c provided in 2b so as to be able to freely slide, the upper metal fitting B can slide extremely smoothly. In addition, even if rust occurs on the metal holder of the present invention, since the upper metal fitting B is loosely inserted into the through holes 2c, 2c of the metal holder main body A, its sliding performance will not deteriorate and it will last forever. A smooth sliding condition can be maintained.

Therefore, by using the present invention in constructing the outer envelope of a construction board in the form of a cross-section or a folded board, it is possible to extremely well cope with the thermal expansion and contraction of the construction board in the longitudinal direction of the outside temperature. It is possible to maintain this good response permanently.

Furthermore, due to the good thermal expansion and contraction properties of the architectural board in the longitudinal direction, it is possible to prevent the occurrence of the plate rattling phenomenon and prevent damage to the bolt attachment points.

In addition, since the section modulus of the top surface 2 of the receiving fitting main body A is increased by the rising pieces 2b, 2b provided on the top surface 2 of the receiving fitting main body A of the receiving fitting of the present invention, the receiving fitting of the present invention It is structurally strong and can be used for constructing the outer enclosure of relatively heavy construction boards.The structure of the receiving bracket of the present invention is extremely simple, and it has excellent workability. It is suitable for mass production and can be provided at a relatively low price.

As shown in FIGS. 8 and 9, if the upper metal fitting B of the receiving metal fitting of the present invention is formed into a curved shape, the outer circumference of the construction board, especially in the form of a ridge or folded plate having a slight inclination, can be formed into a curved shape. Can be used for body construction. That is, as shown in FIG. 9, by shifting and moving the curved upper fitting B on the receiving fitting main body A, the screw rod 5 or the hanger 7 is placed on the structural member 8 such as the purlin or the rim. Therefore, when constructing the outer enclosure of a construction board that is also slightly inclined, there is no need to apply excessive force to the parts where the screw rod 5 or hanger 7 is attached to the construction board and the part where the upper metal fitting B is attached. Can be used without any hassle.
