Description

[Detailed description of the invention] This invention is a wall panel connection device, more specifically, two wall panels with flat plate-shaped rear protrusions protruding backward from both side edges are connected by a joint fitting equipped with screws. This invention relates to a connection device for wall panels.

In the conventional wall panel connection method, as shown in FIG.
Drill 0 and attach the two wall panels 12 with screws 6 and nuts 11.
However, according to this method, the screws 6 were as small as φ4 and difficult to handle, so it was difficult to tighten the nuts 11 when joining the two wall panels 12.

In addition, since the connection is made only with the screws 6 and nuts 11, the connection strength of the wall panel 12 is poor, and furthermore, it is difficult to ensure that the position of the small hole 10 is accurate, so after installation, as shown in Figure 1, the two parts are It was not uncommon for wall panels 12 to have different levels.

The present invention has been provided in view of the above points, and
The purpose of this is to save construction work when joining two wall panels, solve the conventional problem of unevenness between two wall panels, and improve the strength of the joint. Reinforcement of wall panels by.

The present invention will be explained in detail below using examples.

As shown in Fig. 2, the two wall panels 1, each of which has rear projecting pieces 3 and 4 protruding backward from both ends, are joined together using a joint fitting 7 that has a cross-sectional shape. A small hole 2 is bored in one of the back projecting pieces 3 and 4 that protrudes backward from the wall panel 1, and a small hole is formed in the other back projecting piece 4. Do not drill.

On the other hand, the joint metal fitting 7 has a small protrusion 5 having the same inner diameter as the outer diameter of the small hole 2 that protrudes inward from one side piece of the joint metal fitting 7, and a tap cutter is provided on the opposite side piece. Screw hole 8
is provided, and the screw 6 is screwed into this screw hole 8.

However, the length of this small protrusion 5 may be equal to the thickness of the wall panel 1.

When this joint fitting 7 is clamped between the two dorsal projecting pieces 3 and 4, first, as shown in FIG. are brought into close contact with each other, and then the small protrusion 5 provided inside the joint fitting 7 is inserted into the small hole 2 of the dorsal protrusion piece 3 having a small hole.

Next, a screw 6 is screwed into the screw hole 8, and the rear protrusion 4, which does not have a small hole, is pressed against the screw 6.

FIG. 4 is a top view after tightening.

At this time, if there is a difference in level between the two wall panels 1,
By appropriately moving the rear projecting piece 4 without small holes in the front-back direction, the two wall panels will be placed on the same plane.

Also, insert the small protrusion 5 of the joint fitting 7 into the small hole 2 of the back protrusion piece 3.
The wall panel 1 can be completely fixed by inserting it into the wall panel.

Here, the length of the joint fitting 7 having a box-shaped cross section is approximately the same as the height of the wall panel 1.

Therefore, in the present invention, a small protrusion protruding inwardly from one side of the rectangular joint metal fitting of the dorsal protruding piece having a small hole is inserted and screwed into the other side of the waist joint metal fitting. Since the rear protrusion, which does not have a small hole, is pressed together with a screw, it is possible to fix it with only a screw without using a nut, and there is no need to hold a small nut with your fingers at the site. Construction work can be saved, and the difficulty of installation work is eliminated.

In addition, the wall panel is completely fixed by the small protrusion of the joint metal fitting and the small hole drilled in the rear protrusion piece, and in addition, because the joint metal fitting is straight-shaped, the joint metal fitting can be attached to the reinforcing material at the connection part. It serves a dual purpose, improving the strength of the connecting parts of wall panels.

Furthermore, flat plate-shaped rear protrusions are provided to protrude from both side edges of the wall panel, and a small hole provided in one of the adjacent rear protrusions is provided to protrude inward from one side of the joint metal fitting. At the same time, the other rear protrusion piece is held between the small protrusion and the tip of the screw screwed into the other side of the joint metal fitting. the panel can be moved in its thickness direction relative to the other wall panel;
This has the advantage that the surfaces of both wall panels can be adjusted so that they are flat, giving a beautiful appearance.

In addition, when connecting both wall panels with the joint metal fitting, the small protrusion that protrudes from the joint metal fitting is inserted into the small hole, so the joint metal fitting is temporarily fixed to the wall panel.
This has the advantage of making work easier.
