Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field 1] The present invention relates to a construction panel formed by attaching a reinforcement or assembly frame to a construction board.

[Background Art 1] This type of conventional architectural panel A' is formed by attaching the frame 2 to the architectural board 1 via an adhesive 5', but the adhesive strength is still limited to optical spectroscopy. There has been a problem in that the positions of the architectural board 1 and the frame 2 are shifted when the adhesive 5' is not properly bonded and when the adhesive 5' is cured. For this reason, as shown in FIG. 6, screws 7 and the like are used in combination, but this reduces productivity and increases costs. In addition, it is difficult to achieve thickness accuracy of the adhesive 5', and moreover, as shown in FIG.
Not only will the adhesive 5' be lost, but also the adhesive 5' that has protruded out.
had to be removed. Furthermore, when curing the adhesive 5', as shown in Figure 8, it was necessary to stack multiple boards and use something like a weight or a turnbuckle to fix the construction board and frame 7, which resulted in poor productivity. It was put away.

In this case, it is possible to use Motosufu together, but if this is done, the above-mentioned problem will occur.

[Object of the invention] The present invention has been made in view of the above circumstances, and its purpose is to prevent the positional shift between the architectural board and the frame without using screws, and to reduce the thickness of the adhesive. To provide a highly productive construction panel that can control the thickness and improve thickness accuracy, does not allow adhesive to protrude to the edge surface, and does not require any load during curing of the adhesive. be.

[Structure of the Invention] The construction panel of the present invention is a construction panel formed by attaching a reinforcing or assembling frame 2 to a construction board 1. 3
A tacky adhesive 4 is interposed on the outer periphery @ 3 a and an elastic adhesive 5 is interposed on the inner periphery 3 b. With this structure, the above object can be achieved. That is, the tackiness of the adhesive 4 can prevent misalignment between the building board 1 and the frame 2 during adhesion and curing of the elastic adhesive 5, and the load required during curing of the elastic adhesive 5 is also reduced. In addition, the thickness of the elastic adhesive 5 can be controlled by the adhesive adhesive 4 to improve thickness accuracy, and the adhesive adhesive 4 can be attached easily. Since the elastic adhesive 5 is interposed on the outer peripheral portion 3a of the portion 3, the elastic adhesive 5 does not protrude from the end surface.

Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. The building board 1 can be made of asbestos cement board, calcium silicate board, gypsum slag board, plywood, etc., and the reinforcement or assembly frame 2 can be made of metal, wood, plywood, etc.

A sticky adhesive 4 is interposed on the outer peripheral part 3IL of the attachment part 3 between the architectural board 1 and the frame 2, and an elastic adhesive 5 is interposed on the inner peripheral part 3b.
are attached to form a construction panel A. When attaching the frame 2 to the building board 1, apply adhesive 4. to the building board 111Ill. The elastic adhesive 5 may be applied in a bead shape or on the side of the frame 3 as shown in FIG. 3. The functions required of the adhesive adhesive 4 are that it has good workability , It is quick-drying and exhibits adhesive strength immediately when laminated together, has adhesive strength to the extent that it does not cause misalignment between architectural board 1 and 7 frame 2, and once pressure is applied to regulate the thickness, the thickness does not change. In particular, even when used together with the elastic adhesive 5, it is required that the performance of the elastic adhesive 5 is not affected. As the tacky adhesive 4 that satisfies these various functions, a hot melt type adhesive can be mentioned. The elastic i & adhesive 5 is #i adhesive which is the main adhesive force between the architectural board 1 and the frame 2, and is made of urethane-based, silicone-based, acrylic-based, rubber-based, etc., which have excellent durability and elasticity. Modified adhesives can be used. With this elastic adhesive 5, the architectural board 1
Due to the difference in dimensional changes due to heat and moisture between the 7-frame 2 and the 7-frame 2, the stress generated in both is absorbed and alleviated by its elasticity, thereby preventing deformation such as warping of the architectural panel A.

Specifically, each member constituting the architectural panel A is 6 x 1198 x 1898 (mm) as the architectural board 1.
Decorative special asbestos cement board, 7 frames 2 are 1,2

0 x 1900 (mm) metal 7 frames, the adhesive 4 is a hot melt type adhesive manufactured by Cemedine Co., Ltd., and the elastic adhesive 5 is 1 g manufactured by Cemedine Co., Ltd., and a mold-modified silicone adhesive. I can do it. The thickness of the adhesive adhesive 4 and the elastic adhesive 5 is 0.5 to 1.5 m.
o+ degree is preferable.

For example, as shown in FIG. 5, this construction panel A is formed by pasting a construction board 1 onto a frame 2 that has been assembled in advance when assembling equipment units.

be done. Silicone agent 6 may be filled between the building panels A.

[Effects of the Invention] In the present invention, an adhesive adhesive is interposed on the outer periphery of the attachment portion between the architectural board and the 7-frame frame, and an elastic adhesive is interposed on the inner periphery. Due to the adhesiveness of the adhesive, it is possible to prevent misalignment between the building board and the 7 frame during adhesion and curing when the adhesive strength of the elastic adhesive is not yet sufficient, without using screws, etc., and also to prevent the elastic adhesive from curing. No additional load is required, which can significantly improve productivity, and the thickness of the elastic adhesive can be regulated using adhesive adhesive to improve thickness accuracy.
Furthermore, since the adhesive adhesive is interposed on the outer periphery of the M portion, the elastic adhesive does not protrude to the outer periphery end surface.
