Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a siding board useful as an exterior wall material for buildings and structures. More specifically, the present invention relates to a siding board in which a part of an air cycle circulation path is formed in the siding board itself.

Due to the spread of energy conservation laws, the use of insulation materials in houses is steadily increasing. However, the construction of the insulation material at this time was usually to the extent that the insulation material was attached to the rim, or a panel with the insulation material as the core material was constructed. As a result, in houses constructed in this way, it is not possible to prevent condensation from occurring, which may corrode the building materials, or
There were drawbacks such as the glass fiber insulation material being made into a damp cloth (low insulation material). The causes include ○B insufficient insulation in the outer wall of the building, ○B lack of ventilation, ○C insufficient air circulation within the building, and ○D deficiencies in the moisture barrier layer.

In order to eliminate such drawbacks, the present invention integrally forms a synthetic resin foam with a closed cell foam structure on the back surface of an impermeable base material, and provides a recess in a portion of the back surface of the foam. The open end of the is closed with a special sheet-like material, and due to the function of the concave part of this composite, the above ○I ~
We propose a siding board that significantly improves the functions of (2) and prevents internal condensation.

An embodiment of the siding board according to the present invention will be described in detail below with reference to the drawings. 1 is mainly a hard base material, such as a noncombustible board such as a metal plate or gypsum board, which is formed into a concave cross-section and a rectangular long piece, which mainly functions as a surface material and a decorative material (embossed board). It is something. Reference numeral 2 denotes a male connecting portion, and an insertion edge 3 protrudes outward from one end of the main body 1.
4 is a female connecting part which bends the other end of the main body 1 inwardly, protrudes outward again to provide an insertion groove 5, and extends the lower edge 6 of the insertion groove 5 outwardly. It is extended to form an extension part 7. 8 is a protrusion that is provided as necessary in the middle of the extension part 7;
Numeral 10 is a tongue piece formed at the tip of the insertion edge 3 and the extension part 7 as shown in FIG. It has a function of imparting elasticity to the board connecting portion. 11 is a heat insulating layer made of a synthetic resin foam with a closed cell structure, such as polyurethane foam, polyisocyanate foam, phenol foam, styrene foam, polyester foam, polyacetal foam, vinyl chloride foam, polyethylene foam;
The concave shape of the main body 1 and the male and female connecting parts 2 and 4
The bulging portion 12 protruding downward from the back surfaces 2a and 4a of the bulging portion 12 and the vicinity of the male connecting portion 2 are
It is composed of a notch portion 12a that is recessed over the entire length. Note that the heat insulating layer 11 is formed by using a molded body or by foaming raw material on the back surface of the main body 1 and integrally molding it with a mold, and also functions as a core material.
Moreover, the thickness H ₁ to _{H 3} of the heat insulating layer 11 is H ₁ > H ₂ H ₃ ,
H ₁ = about 10 to 100 mm, H ₂ = 4 mm or more.
The reason why H ₂ is set to 4 mm or more is that the heat insulation properties of the joints when the siding boards are connected to each other have a large effect on the occurrence of dew condensation. 13 is a concave part, for example, a third
From the back surface 11a to the main body 1 in the shape shown in Figures a to f.
It is recessed in a straight line toward the back surface 1a of the main body 1 and parallel to the side wall 1b of the main body 1, and is mainly formed by molding or cutting. In addition, H ₄ is H ₁ = 50
mm, approximately 20 mm is appropriate, and this is a gap that does not disturb air convection. Of course, H ₄ can also be dimensioned larger in relation to H ₁ in order to increase the chimney effect. Reference numeral 14 is a sheet that covers the opening surface of the recess 13 and serves as a partition and an intake/exhaust member that allows the recess 13 to function as an air circulation path 16. Micropore 1 of size
5 are drilled in large numbers. The sheet 14 is made of one or more of the following materials: waterproof sheet, paper, metal foil, and synthetic resin film. In addition, the air circulation path 16
As shown in Figure 4, the attic 17 and the underfloor 1 of the building are
8 and is useful for causing convection between the two parts without causing turbulence.

Next, a construction example will be explained.

That is, in order to form the outer wall of a building using siding boards as shown in Fig. 1, siding boards _A1 are fixed on the rim C with nails B as shown in Fig. 5, and then siding board
Insert the insertion edge 3 of the siding board A ₂ into the insertion groove 5 of A ₁ . Therefore, in order to form the outer wall, such operations may be repeated in sequence. In addition, in the height direction, as shown in Figure 4,
A drainer D is fixedly installed on a base E, and the back side of the siding board is pressed against it, so that the protruding side D' of the drainer D sticks into the heat insulating layer 11 and closes the lower end of the air circulation path 16. Furthermore, at the end of the siding board A ₁ on the girder side, a stop edge F closes off the upper end of the air circulation path 16 .

In buildings constructed in this way, the temperature on the indoor surface tended to approach room temperature. Moreover, no condensation occurred because the air circulation path 16 functioned to perform an air cycle between the upper and lower parts of the building, and the building had sufficient heat insulation.

What has been described above is only one embodiment of the siding board according to the present invention, and the micropores may be provided only in the vicinity of both longitudinal ends of the siding board. This is to prevent insufficient convection if the micropores are provided throughout the open end of the recess.

As described above, the siding board according to the present invention has the feature that an air circulation path for preventing dew condensation can be easily formed at the same time as the siding board construction without impairing the heat insulation properties.
