Description

[Detailed Description of the Invention] This invention relates to a panel joining device that is applied to prefabricated buildings and the like.

BACKGROUND ART Conventionally, a prefabricated structure such as a storage shed as shown in FIG. 1 has been manufactured. In FIG. 1, 1 is a foundation, 2 is a wall panel erected on the foundation 1, 3 is a door, 4 is a roof, and 5 is a panel holder.

In such a prefabricated building, the panel joining device for joining the wall panels 2, 2 is
As shown in the figure, there is a panel presser 5 that integrates a lip groove-shaped member and a hat-shaped member with a nut 6 fixed to the inner surface of the top plate, this panel presser 5, a wall panel 2,
a panel presser 7 having a U-shaped cross section and facing each other with the panel holder 2 in between;
It consists of a screw 8 that fixes the panel holders 5 and 7 to each other.The panel holder 5 is fitted from the outside into the gap between the butt parts of the wall panels 2 and 2, and the panel holder 7 is covered from the inside, and the screw 8 is inserted from the inside to the panel holder. By tightening the panel holder 7 to the nut 6, the distance between the panel holders 5 and 7 is reduced, and the wall panels 2 and 2 are pressed together by the panel holders 5 and 7. In this case, in order to position the wall panels 2, 2 in the lateral direction, grooves 2a, 2a are provided near the abutting portions of the inner surfaces of the wall panels 2, 2, and the panel presser 7 is fitted into the grooves 2a, 2a. It is crowded. Note that the wall panel 2 has an exterior material 10 on the outer surface of the heat insulating panel (or heat insulating material) 9.
It is constructed by pasting.

However, such conventional panel joining equipment
Since the panel pressers 5 and 7 were fixed with screws 8 and nuts 6, it was not easy to align the screws 8 and nuts 6, making construction difficult. Furthermore, since the nut 6 was fixed to the panel presser 5, there was a problem in that the panel pressers 5 and 7 could not be fixed at positions other than the nut fixing position.

Therefore, the purpose of this invention is to provide a panel joining device that is easy to install and allows the fixing position to be arbitrarily selected.

An embodiment of this invention is shown in FIGS. 3 to 6. That is, this panel bonding device includes a panel presser 11 having a substantially convex cross section and a slit 11a in the longitudinal direction at the center of the upper surface as shown in FIG.
As shown in the figure, there is a panel presser 12 which is long plate-shaped and has a slit 12a in the longitudinal direction in the center, and a panel presser 12 which is approximately H-shaped as shown in FIG. Reverse slope lateral taper 13d
As shown in FIG. 3, a panel presser 11 is inserted from the outside into the gap between the abutting parts of two wall panels 2', 2' arranged side by side.
Insert the wall panel 2' with 1a inside, and
2' is covered with the panel presser 12 from the inside so that the slit 12a faces the slit 11a, one vertical piece 13a of the fastening metal fitting 13 is passed through the slits 12a, 11a from the inside, and the other side of the fastening metal fitting 13 is inserted. By rotating the clamp 13 approximately 90 degrees around the horizontal piece 13b with the vertical piece 13c, the interval between the panel holders 11 and 12 is reduced by the action of the lateral taper 13d, and the panel holders 11 and 12 are attached to the wall panel. It is designed to be brought into pressure contact with the abutting portions of 2' and 2'. In this case, the width D of the slits 11a, 12a is larger than the thickness D' of one vertical piece 13a of the fastening metal fitting 13, and
is set to a size that allows it to rotate freely within the slits 11a and 12a, and the horizontal piece 13 of the fastening fitting 13
The length b is set to a length that can hold the wall panels 2', 2'. The wall panel 2' is constructed by pasting an exterior material 15 on a heat insulating material 14.

In this way, two wall panels 2′,
2' is sandwiched between panel holders 11 and 12, and the space between the panel holders 11 and 12 is reduced by rotating an H-shaped fastening fitting 13, so that the wall panels 2' and 2' are brought into pressure contact with the abutting portions. This eliminates the need for conventional screws and nuts, and also eliminates the need for jigs, making installation easier and allowing the fixing position to be selected arbitrarily.

As mentioned above, the panel joining device of this invention is
A first slit having a generally convex cross-section and having a first slit in the longitudinal direction at the center of the upper surface, the first slit being fitted from the outside into the gap between the abutting portions of two wall panels arranged side by side with the first slit facing inward. A panel retainer, which has a long plate shape and has a second slit in the longitudinal direction in the center, is placed over the abutting portion of the two wall panels arranged side by side so that the second slit faces the first slit. a second panel retainer having a substantially H shape and having a horizontal taper with an opposite slope at the top and bottom with the horizontal piece as a boundary on the inner surface of one vertical piece; The space between the first and second panel holders is reduced along the lateral taper by passing them through the slits and rotating them about the lateral pieces, so that the first and second panel holders are arranged side by side. Since it is equipped with a fastening fitting that is pressed into contact with the abutting portions of the wall panels, construction is easy and the fixing position can be arbitrarily selected.
