Description

[Detailed Description of the Invention] The present invention relates to a panel joint device that can extremely firmly connect panels used for roofs, floors, partitions, wall studs, etc. by simply press-fitting them.

To explain the proposed device in the case of controlling roofs, floors, walls, etc. shown in Figure 1, A in the figure is a connecting body, which is shaped by a single elastic metal plate and is flat. Folded bottom 5
The inverted L-shaped pieces 1, 1 rising up and protruding from each other are each provided with a bent groove part 2.2 in the middle, and the inverted L-shaped pieces 1, 1 are symmetrically close to each other and the new curved groove parts 2, 2 are gathered together. A congruent space C is formed.

In use, the bottom part 5 is attached to the substrate by any suitable method.

B is a panel constituting a roof, floor, wall, etc., whose inwardly bent edges are bent at right angles to the surface, with bent inwardly bulging parts 3, 3 provided in the middle, and an edge on the surface. A bent inward bulge portion 4 is formed near the portion.

To explain these in more detail, a bent groove part 2 is provided in the middle of the vertical part, and an inverted L-shaped piece 1 is formed with an inward bent part at the edge of the horizontal top part that is continuous with the vertical part in an inverted L shape. , 1 are symmetrically brought into close contact with each other to form a retaining space C by the adjacent bent grooves 2, 2, between the adjacent vertical parts of the connecting body A, there is an inward bend in the middle of the vertical bent edge. A pair of vertically bent edges of panels B and H are provided with bulging portions 3, 3 and bent inward bulging portions 4, 4 near the end of a horizontal portion continuous with the vertically bent edge. At the same time, the inwardly bent portions at each end of the horizontal top portion of the connecting body A are pushed in simultaneously or separately so that the bent inwardly bulging portions 3, 3 are engaged with the engagement space C, and the inwardly bent portions at each end of the horizontal top portion of the connecting body A are bent. The panel joint device of the present invention is made to press against the inner inclined walls of the inwardly bulging portions 4, 4, so that both horizontal top portions of the connecting body A are brought close to each other.

During construction, the inwardly bent edges of a pair of panels B and H are pressed together or separately between the inverted L-shaped pieces 1 and 1 of the connecting body A, and the bent inwardly bulging portion of the panel is inserted. 3, 3 are press-fitted into the engagement space C of the connecting body A, and the inverted L-shaped pieces 1, 1 where the double-folded inward bulges 4, 4 of the panel are about to expand. It is pressed against both the left and right top surfaces, and the tops are forcibly pressed so that they approach each other (see FIG. 2).

Therefore, even if you try to pull out the panel after installation, it will turn upside down.
It is impossible to escape the panel because the letter pieces 1 and 1 do not open left and right.

As is clear from the above, according to the present invention, the panel can be installed in a state where it cannot escape by simply pushing the inwardly bent edge of the panel into the connecting body, without using any other means, and the construction is easy. This allows for a simple and extremely strong connection.

In addition, the angle α of the bent inward bulge 4 and the top angle α of the inverted L-shaped piece 1
By adjusting , it is possible to adjust the adhesion force between the two.

Fig. 3 shows an example in which the proposed device is used for partitions, wall studs, etc. In this case, two sets of inverted L-shaped pieces 1, 1 are arranged on a straight line, and the middle is fixed by welding or clamping D. This is the same as in FIGS. 1 and 2 except that

The device of the present invention can be applied not only to construction but also to general applications such as installation of decorative panels.
