Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a panel connection structure for a corner portion of a so-called equipment unit, etc., which forms a room using panels and supports.

[Conventional technology]

Regarding the conventional panel connection structure,
Publication No. 38809, namely, as shown in FIG. 5, the corners formed by the adjacent substrates 2, 2 of the rectangular prism are cut, and an opening is formed between the substrates 2, 2, and both substrate ends are cut. A metal corner material 1 having a support piece 11 facing the substrate 2 and having an outward inclination of 45 degrees is fixedly erected at the corner, and at least the corner material 1
The bent pieces 10 of two orthogonal panels having 90-degree bent pieces 10 on the sides are inserted into the opening of the corner material 1 with the panels 8 orthogonal to each other, and the tips of the support pieces 10 of the corner material 1 are inserted. The corner material 1 is placed on the back surface of the panel 8 and the inside of the panel folded piece 10 is in contact with the inside of the corner material 1, and the joint material 15 having a fin portion is inserted between the panel corners in the opening. In this structure, a panel 8 is clamped between the inner side of the corner material support piece 11 and the joint material 15.

[Problem that the invention attempts to solve]

However, the conventional example had the following problems.

1. In order to drive the joint material 13 between the panel corners, a special tool 16 is required, and moreover, it requires skill. Therefore, if you are inexperienced, there is a risk that the panel will be damaged or dented due to mistakes, or that you may overfill the joint material.

2. In order to secure the wall panel fixing strength, the joint material must have a certain degree of strength, so the joint material could not be made extremely small, which would impair the appearance.

3. In order to ensure water sealing between panels using a joint material, it is necessary to strictly ensure the dimension a between the panels, which requires high assembly accuracy and requires a lot of work time.

The present invention was devised in view of the above-mentioned drawbacks, and it is an object of the present invention to provide a panel connection structure that has good appearance and water-tightness and is easy to assemble.

[Means for solving problems]

The structure of the present invention for achieving the above object will be explained using FIGS. 1 to 4 corresponding to the embodiment. A corner material 1 with an opening 3 formed between the substrates 2 and 2 by cutting the corner material 1 is erected, and inside the corner material 1, mutual leg portions 5 and 5 having an L-shaped cross section are in contact with the inner wall of the corner material 1. In addition, an inner spacer 4 with a bulge 7 formed on the outside perpendicular to the legs 5, 5 is inserted so that the bulge 7 faces the opening 3, and the bent pieces of the two panels 8, 8 are folded. 10, 10 are inserted into the opening 3, and the folded pieces 1 of the panels 8, 8 are inserted.
0 and 10 are sandwiched between the bulge 7 of the inner spacer 4 and the inner wall of the corner material 1.

[Effect]

According to the present invention, in order to assemble a panel into a corner material by the above-mentioned means, an L-shaped corner material having abutment pieces 12, 12 is placed on the inside of a corner material 1 which is a rectangular prism with an opening 3 between supporting pieces 11. An inner spacer 4 having an arcuate bulge 7 having projections 6, 6 at both ends on the outside perpendicular to the legs 5, 5 is inserted so that the bulge 7 faces the opening 3. ,
The inner spacer 4 is fixed by bringing the abutting pieces 12, 12 of the inner spacer 4 into contact with the inner wall of the corner material 1, and the opening 3 is turned indoors and becomes self-supporting. In this case, as shown in FIG. 4, elastic bodies 9 are attached to both ends of the bulging portion 7 of the inner spacer 4, that is, between both protrusions 6, 6 and the substrates 2, 2 of the corner material 1. bent piece 1
A gap is formed in which the elastic body 9 can be pressed against the protrusion L and inserted. Then, the bent piece 10 of the panel 8 to which the elastic body 9 is attached is pressed into the gap between the arc-shaped bulge 7 of the inner spacer 4 and the substrate 2 of the corner material 1 to fit the panel 8.
is held between the corner members 1.

Therefore, the connection strength is as shown in Figure 4.
When a force in the direction A is applied to the panel 8 from inside the room, the tip of the support piece 11 of the corner material 1 will move against the panel 8.
Since the bent piece 10 of the panel 8 is clamped between the substrate 2 of the corner material 1 and the bulging portion 7 of the inner spacer 4 on the back side, the force in the A direction is applied to the corner material 1 from the support piece 10. A force in the direction A is applied to the substrate 2 of the corner material 1 that indirectly faces the corner material 1 . However, in addition to the rigidity of the corner material 1, the bent piece 10 has a very strong strength due to the effect of the tensile rigidity of the adjacent panel 8' to which the other one is fixed.
Furthermore, when a force in the B direction is applied to the panel 8, the bent piece 10 of the panel 8 is clamped between the substrate 2 of the corner material 1 and the bulge part 7 of the inner spacer 4, and the friction resistance In addition, since the elastic body 9 of the panel 8 is firmly fixed by the bonding force engaged with the protrusion 6 of the bulge 7, the panel 8 will not come off.

Furthermore, by providing the abutting piece 12 of the inner spacer 4, the inner spacer 4 can be prevented from moving to the corner facing the opening 3 of the corner material 1, and the bulge 7 of the inner spacer 4 can This allows the panel folding piece 10 to be firmly fixed.

Furthermore, since the bulging portion 7 of the inner spacer 4 is formed in an arc shape, the panel 8
The inner spacer 4 can be easily inserted and fixed between the substrate 2 and the bulge 7 of the inner spacer 4.

[Effect of idea]

Since the present invention has the above configuration, it has the following effects.

1. There is no need for joint material to be driven between panel corners, there is no need for special tools or work that requires experience, and there are no scratches or dents on the panels. In addition, the sealing material is simply filled in the space created by the corners of the panel and the inner spacer, and no experience is required for the work.

2. Panel fixing strength is ensured by the elastic inner spacer and corner material substrate. Moreover, since the dimensions of the inner spacer and the corner material can be set relatively freely, the dimension a between the wall panels can be reduced and the appearance can be improved.

3 To seal off the water between panels, simply fill the space created by the corner of the panel and inner spacer with sealant, and there is no need to strictly ensure the dimension a between the panels, making assembly work easier. Therefore, the work time can be reduced.
