Description

[Detailed Description of the Invention] This invention relates to a board bonding structure in which a decorative board is bonded to the surface of a heat insulating board.

2. Description of the Related Art Boards used for the inner walls of buildings such as warehouses are constructed by laminating a decorative board onto the surface of a heat insulating board, which is conventionally joined as shown in FIG.

That is, as shown in the figure, board A is constructed by laminating a decorative board 2 such as alkali-resistant glass fiber reinforced cement (commonly known as FRC) on the surface of a heat insulating board 1 such as a wood wool cement board or a resin porous board. The board A is pasted on the inner surface of an outer wall B, such as concrete, of a building, and adjacent boards A are butted and joined with a joining tool C interposed.

The joint tool C includes a web 3 sandwiched between both boards A,
A front flange 4 provided on the front surface of the web 3 and applied to the surface of the decorative board 20, and a rear flange 5 provided on the rear surface of the web 3 and applied to the back surface of the board A (between the heat insulation board 1 and the outer wall B). The structure is such that the board A is held and joined by both flanges 4 and 5.

By the way, if the connecting tool C is in contact with the outer wall B as in the conventional case shown in Fig. 1, if a temperature difference occurs between the outside and the inside of the building, the connecting tool C will be heated by the outer wall B facing the outside. Alternatively, the joint tool C may be cooled, causing a temperature difference between the joint tool C and the inside of the building, resulting in a reduction in the heat insulation effect and the disadvantage that dew condensation may occur on the joint tool C.

This invention aims to provide a board joining structure that prevents the joining tool C from coming into contact with the wall and prevents dew condensation.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

Note that the same symbols as above indicate the same thing. Figures 2 and 3
As shown in the figure, the joining tool C connects the board A to be butted together.
Consisting of a web 10 sandwiched between, a front flange 11 provided on the front surface of the web 10 and applied to the surface of the decorative board 2, and a rear flange 12 provided on the rear surface of the web 10 and fitted into both boards A. There is a fitting hole 1 between the heat insulating board 1 and the decorative board 2 at the butt part of both boards A.
3 is formed.

Note that the connector C may be formed by bending a metal plate as shown in the figure, or may be integrally molded from resin.

When using board A as the inner wall of a building,
As shown in FIGS. 2 and 3, the boards A are pasted on the inner surface of the outer wall B using an adhesive or the like, and the adjacent boards A are butted together with a joining tool C interposed therebetween, and the rear flange 12 of the joining tool C is attached. Fit into the fitting hole 13, and both flanges 11
．． Hold decorative board 2 with 12, and connect both boards A with joint tool C.
Build the inner wall by joining.

At this time, the board A and the connector C may be bonded together using an adhesive or the like.

In addition, in the above embodiment, the insertion hole 13 is connected to the heat insulating board 1 and the decorative board 2.
However, as shown by the dashed line in Figure 3,
The insertion hole 13 may be formed within the heat insulating plate 1.

Also, as in the example, board A is not connected linearly (
Even if they are butted against each other at an angle, both flanges 11 and 12 of the connector C may be bent at the center (web 10 portion) in accordance with the angle.

As mentioned above, according to the board joint structure of this invention,
The rear 7 lunges of the connector do not touch the exterior wall, and the joint surface behind the rear 7 lunges is insulated from the outside by the insulation board, which contacts the joint surface and is insulated from the outside by the insulation board, so there is a temperature difference between the outside and the inside of the building. Even if this occurs, the joining tool will not be heated or cooled (
, condensation does not form on the joint, and the heat insulation effect is improved.

Claims (1)

[Scope of utility model registration request] In a board joining structure in which boards with a decorative board pasted on the surface of a heat insulating board are butt-joined with a joining tool interposed, the joining tool includes a web sandwiched between both boards, and a web provided on the front surface of the web. It has a cross-sectional shape consisting of a front flange that is applied to the decorative board surface of both boards, and a rear flange that is provided on the rear surface of the web and is fitted into both boards. A fitting hole is formed inside the heat insulating board or between the heat insulating board and the decorative board, and the rear flange of the joining tool is fitted into the hole, and the front and rear flanges sandwich the boards to join both boards. The joint surface of the board is a board joint structure in which the insulation board surface is in contact with the joint surface.
