DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The fastening metal fittings for the edge portion of the hollow molded outer wall plate of the present invention will be described below with reference to the drawings. Figure 1 (a)
(B) is a perspective view and a plan view showing an example of a fastening metal fitting A according to the present invention. The fastening bracket A includes a fastening plate body 10 and an elongated hole 1 formed in the fastening plate body 10.
1 and a thread cutting screw 12 which is inserted into the elongated hole 11.

The fastening plate body 10 is a plate-shaped member having a semicircular cross section, and is a flat surface having a length dimension that can be inserted into the through holes 2 of the outer wall plates 1 and 1 facing each other. It is formed in a rectangular shape as viewed. A long hole 11 is formed in the top of the fastening plate body 10 along the length direction.

A thread 12 is inserted into the long hole 11. The head 12a of the screw 12 has a diameter larger than the width of the elongated hole 11, so that the screw 12 is movably engaged in the longitudinal direction of the elongated hole 11.

As shown in FIG. 2, by using the fastening bracket A, the outer wall plates 1 and 1 which are adjacent to each other with a gap 14 therebetween are fastened to the base 5, and the length of the fastening plate body 10 is set. Both ends 10a and 10b in the direction are inserted into the through holes 2 of the outer wall plates 1 and 1, respectively. Then, the screw 12 is inserted from the gap 14 into the elongated hole 11 and moved in the elongated hole 12 to be positioned at the approximate center of the gap 14. Then, the screw 12 is screwed into the base 5.

When the screw 12 is screwed into the base 5,
The head 12a of the screw 12 applies a pressing force to the peripheral portion of the elongated hole 11 toward the base 5 side. Thereby, the fastening plate body 1
0 moves to the base 5 side, and both ends 10a,
The edge portions of the outer wall plates 1 and 1 are sandwiched between 10b and the base 5.

Therefore, by using the fastening metal fitting A, the edge portions of the outer wall plates 1 and 1 are securely clamped and fixed. Moreover, the outer wall plates 1 and 1 are free to slide in the lengthwise direction, and the edge portions thereof are not damaged by the expansion and contraction thereof.

Further, in the above embodiment, the cross section of the fastening plate body 10 has a semicircular shape, but the invention is not limited to this.
A member having a U-shaped cross section as shown in FIG. 3A, or a flat rectangular metal fitting as shown in FIG. 4 can sufficiently serve as the fastening plate material.

Further, as shown in FIG. 4 (b), the fastening plate body 10 of FIG. 4 (a) can be arranged in the opposite direction. This may be convenient because the contact area with the material (the inner wall of the through hole 2) becomes large.

In the above description, the thread cutting screw 12 is used, but the present invention is not limited to this, and the base 5 may be perforated and fixed by using a normal screw or a half thread cutting screw. Furthermore, although the present invention is applied to the hollow molded outer wall plate having the through holes 2, it goes without saying that
If at least at least a plurality of parallel holes are formed in the longitudinal direction from the end face, this method can be adopted.

[0019]

As described above, according to the fastening member for the edge portion of the hollow molded outer wall plate of the present invention, both ends of the fastening plate member in the length direction are opposed to each other. The screws inserted into the holes and inserted into the long holes of the fastening plate are screwed into the substrate, so that the entire fastening plate moves to the substrate side and the edge of the outer wall plate moves to the substrate side. Since it is pressed firmly, the edge of the outer wall plate can be securely clamped and fixed to the base.

Moreover, the fastened outer wall plate is free to slide in the lengthwise direction, and the end edge portion thereof is not damaged due to its expansion and contraction.
