DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 and 2 showing a building board 1 according to an embodiment of the present invention, the board 2 of the building board 1 is made of solid wood. ,
Plywood, laminated wood, laminated veneer, wood fiber board, particle board and other wood boards are used.

Most preferably, a wood fiber board is used as the substrate of the architectural board of the present invention. Wood fiber board defibrate wood chips obtained by cutting hardwood or softwood raw wood,
It is generally manufactured by press-molding the obtained wood fiber, and a hard layer is formed on the front and back surfaces thereof. The hard layer on the front and back surfaces is formed when the fiber mat obtained by forming the wood fiber is pressed and formed, and has a high specific gravity, is hard, and has low hygroscopicity.

When used as a substrate of a building board of the present invention, the specific gravity of the wood fiber board is preferably about 0.6 to 1.1. When the specific gravity is smaller than 0.6, when used as a floor base plate or the like, the strength against overload becomes low and becomes unsuitable for practical use. Conversely, when the specific gravity exceeds 1.1, the weight increase becomes remarkable. Transport and construction of building boards becomes difficult.

A moisture-proof airtight sheet (not shown) can be attached to the front and back surfaces of the substrate. The moisture-proof airtight sheet is a sheet having airtightness that does not allow liquid moisture or gaseous water vapor or moisture to pass therethrough. For example, a polyethylene terephthalate resin (PET) is formed on the front and back of a core layer composed of an aluminum foil or an aluminum vapor-deposited layer. ), Vinyl chloride resin,
A three-layer structure in which front and back layers made of a synthetic resin such as a polypropylene resin and a polyethylene resin are laminated can be used. By adhering the moisture-proof airtight sheet, the airtightness and heat insulation as a building board are improved,
The effect becomes more remarkable as the area covered with the moisture-proof airtight sheet becomes larger, so that it may be stuck not only on the front and back surfaces of the substrate but also on the edge of the substrate. In addition, since moisture absorption and desorption of the substrate is suppressed in a portion covered with the moisture-proof airtight sheet, the dimensional stability is also improved.

In the configuration shown in FIGS. 1 and 2, the hermetic packing 3 is provided with an elastic tip covering portion 3a for covering the tip of the substrate 2 and a portion near the tip of the front and back sides of the substrate 2 continuous with the tip opening. A pair of side portions 3b. 3b, and is formed in a substantially U-shaped cross section.
Are fitted on the four circumferences of the substrate 2 to form the building plate 1.

The hermetic packing 3 is obtained by molding a rubber-based material such as natural rubber or synthetic rubber, or various synthetic resin-based materials into a predetermined shape. As will be described later, the hermetic packing of an adjacent building plate is used. In order to close each other and eliminate the gaps between the building boards by pressing and deforming the facing edge portions, it is necessary that at least the edge portion 3a is soft and elastic.

Further, it is desirable that the side portion 3b of the airtight packing also has elasticity, so that, as described later,
When the building board 1 is nailed to the structural material at the time of construction with a nail or the like, the side surface portion 3b can be brought into close contact with the structural material, which contributes to further improving the airtightness in the room.

In general, the hermetic packing 3 is obtained as an integrally formed product having a kiguchi covering portion 3a and a side portion 3b by molding an elastic material such as the rubber material or the synthetic resin material described above into a predetermined shape. Kiguchi covering part 3a also side part 3b
Also have the required elasticity, and can exhibit the above-described respective effects.

When the hermetic packing 3 is formed to have a substantially U-shaped cross-section, the elasticity of the material of the hermetic packing 3 is used because the opening of the board 2 is fitted between the pair of side portions 3b, 3b. Can be fitted to the four circumferences of the substrate 2, but if necessary, the glue of the glue of the substrate 2 and the inner surface of the glue coating 3 of the airtight packing are adhered via the double-sided tape 4 as shown in FIG. This prevents the airtight packing from falling off.

FIG. 3 shows an example of the construction structure according to the present invention obtained by connecting construction plates 1 and 1 shown in FIGS. 1 and 2 on a structural material (post) 5. More specifically, the building boards 1, 1 are brought into contact with each other on the structural material 5 by pressing the wooden sealing portions 3a, 3a of the airtight packings 3, 3 facing each other so that there is no gap therebetween, and butt them on the structural material 5, and the side portions 3b on the front side , 3b from the nails 6 (or screws,
(Fixing means such as staples). Due to the elasticity of the airtight packing described above, the building plates 1, 1
The two members are closely butted against each other in a state where there is no gap, and are also fixed by being pressed against the structural member 5 in a pressed state, so that the airtightness in the room can be maintained at a high level.

Further, in this construction, since the wood-sealed portions 3a and 3a of the hermetic packings 3 and 3 are pressed against each other, the substrate 2 is pressed toward the wood-mouthed portion 3a even inside the hermetic packing 3. When the double-sided tape 4 is used, the elasticity of the double-sided tape 4 is combined with the substrate 2 and the airtight packing 3.
Good airtightness is also secured between the two.

FIGS. 4 to 7 show a modification of the shape of the hermetic packing 3, and particularly show a modification of the shape of the opening 3a.

As shown in FIG. 4 and FIG. 5, a convex portion and a concave portion which can be fitted to each other can be provided on the front end surface of the lip end portion of the airtight packing. In the figure, a concavo-convex shape uneven portion is formed.

Further, as shown in FIG. 5, the tip end surface of the mouth opening of the hermetic packing may have a curved shape. Moreover,
As shown in FIG. 6, a hollow molded member 3c formed of a separate member may be joined to the kiguchi covering portion. Such a hollow molded member 3c is easily elastically deformed when the airtight packings are butted against each other, and is excellent in the effect of maintaining a high airtightness.

The side surface portion 3b of the hermetic packing 3 covers at least the vicinity of the opening at one side of the substrate 2,
As shown in FIG. 8, an airtight packing 3 'having only one side portion 3b may be used. In this case, a pair of side surfaces 3
b, 3b, it is not possible to exert the function of sandwiching and fitting the opening of the board 2 between them, so that it is necessary to prevent the airtight packing 3 from dropping off the board 2 by using a fixing means such as a double-sided tape 4 or the like. .

[0024]

According to the construction board of the present invention, since airtight packing is fitted around the four sides of the substrate,
A good airtight state can be obtained only by pressing the airtight packings of the adjacent building boards against each other and performing abutting work, resulting in excellent work efficiency.
