FIG. 1 is a diagram showing a moisture-proof structure according to one embodiment of the present invention.

In the figure, reference numeral 40 denotes a concrete foundation, on which a first floor panel 42 is mounted, and a semi-base 41 is mounted on the outer periphery thereof.

A plurality of wall panels 43 constituting a wall portion are erected and fixed on the floor panel 42. Further, a second floor panel 45 is mounted on the wall panel 43, and the outer periphery of the second floor panel 45 is attached to the outer periphery thereof. 44 are attached.

A ceiling 55 is formed above the wall panel 43 on the first floor and below the floor panel 45 on the second floor. A ceiling is also formed on the upper part of the wall panel on the second floor. The ceiling portion 55 is in a state in which a grid-like field edge 47 is suspended and supported by a ceiling suspension beam extending between upper portions of the wall panel 43 via a ceiling suspension tree 49 and a field edge receiver 48.

The moisture-proof building material 1 is mounted on the indoor side of the wall formed by the wall panel 43 and the ceiling 55.

As shown in FIGS. 2 and 3, the moisture-proof building material 1 includes a gypsum board 2 as a face material and a gypsum board 2
Is integrally formed with a vinyl sheet 3 as a moisture-proof material, which is bonded to the back surface with a vinyl acetate-based adhesive 4 having excellent moisture-proof properties.

The thickness, width and length of the gypsum board 2 are set in accordance with the portion where the gypsum board 2 is to be attached.
For example, thickness 9 mm (or 12 mm) x width 300 mm x height 1820 mm, thickness 9 mm (or 12 mm) x width 91
It is formed to have a size of 0 mm × 1820 mm in height, or 9 mm (or 12 mm) in thickness × 910 mm in width × 2420 mm in height.

Further, the vinyl sheet 3 is formed to be larger than the gypsum board 2 by a predetermined area, and a pair of adjacent edges 31 and 32 of the vinyl sheet 3 are connected to a pair of adjacent edges 21 of the gypsum board 2. , 22 are adhered. As a result, the protruding portion 3 protruding, for example, by about 100 mm in the joining directions A and B of the gypsum board 2
3, 34 are formed.

Although the gypsum board 2 generally used as a face material is used here, the invention is not limited to this, and examples thereof include plywood, calcium silicate (silical board), and hard wood cement board. , Asbestos board or the like can be used.

Although the vinyl sheet 3 is used as the moisture proof material, the invention is not limited thereto, and a synthetic resin film or sheet such as a polypropylene film or a polyethylene film, or a moisture proof film or sheet such as a moisture proof paper may be used. can do.

Further, the adhesive 4 is not limited to vinyl acetate, as long as it is capable of closely bonding the face material and the moisture-proof material and has excellent moisture-proof properties.
For example, a vinyl acetate / acrylic, ethylene / vinyl acetate, acrylic / ethylene, or urethane adhesive can be used.

The protruding portion 33 of the vinyl sheet 3
Are formed so as to protrude in the directions of the arrows A and B in FIG. 2, but may be formed so as to protrude in the directions opposite to the directions of the arrows A and B.

When attaching a plurality of such moisture-proof building materials 1 to the wall panel 43, first, one of the moisture-proof building materials 1 (for example, the moisture-proof building material located on the left side of FIG. 1) so that the protruding portion 33 of the vinyl sheet 3 faces upward. ) Is erected, the surface of the vinyl sheet 3 is applied to the wall panel 43 whose surface is coated with caulking, and the gypsum board 2 is attached to the wall panel 43 by nailing or the like.

Then, the left edge of the moisture-proof building material 1 to be attached next is superimposed on the protruding portion 34 of the attached moisture-proof building material 1, and the left edge 21 of the gypsum board 2 to be attached is attached.
The gypsum board 2 is attached to the wall panel 43 by nailing or the like so that the gypsum board 2 is in contact with the right side edge of the gypsum board 2 already attached. In this way, as shown in FIG. 4, the plurality of moisture-proof building materials 1 are sequentially attached in the direction in which the wall panels 43 are connected.

The wall panel 43 as shown in FIGS.
When the board 46 is attached above the moisture-proof building material 1, the upper protruding portion 33 of the moisture-proof building material 1 to be stuck is cut or bent and the moisture-proof building material 1 is stuck.

FIGS. 1 and 4 show a case in which the height of the wall panel 43 is not so large and the wall panel 43 can be covered with one piece of the moisture-proof building material 1 in the height direction. As shown in FIG. The moisture-proof building material 1 is also attached to the wall panel 43 forming a certain atrium or the like in the joining direction A.

That is, as shown in FIG. 6, after a plurality of moisture-proof building materials 1 are pasted in the joining direction B by the above-described method, the protruding portions 33 of the moisture-proof building materials 1 already pasted.
The lower edge of the moisture-proof building material 1 (downward in FIGS. 5 and 6) is superimposed on the gypsum board 2, and the lower edge 22 of the gypsum board 2 to be abutted comes into contact with the upper edge of the gypsum board 2 already applied. Then, the gypsum board 2 is nailed to the wall panel 43. In this manner, the plurality of moisture-proof building materials 1 are sequentially attached to the wall panel 43 along the joining direction A.

As a result, the edges of the vinyl sheets 3 and 3 of the moisture-proof building material 1 located above and on the right side of the moisture-proof building material 1 abut on the upper and right protrusions 33 and 34 of the moisture-proof building material 1 already attached. Since the overlapping portions are pressed against the wall panel 43 in a state where they are in close contact with each other by nailing of the gypsum board 2, the overlapping portions of the adjacent vinyl sheets 3, 3 are completely airtight.

Therefore, if a plurality of moisture-proof building materials 1 are attached to the wall panel 43, substantially the same effect as covering the entire wall panel 43 with one large vinyl sheet is obtained.
The gap 50 between the wall panels 43 is a plurality of vinyl sheets 3
With this, it is completely closed from the indoor side.

As a result, the indoor humidity is reduced by the vinyl sheet 3.
As a result, there is no intrusion into the gap 50 of the wall panel 43, and no indoor heat escapes from the gap 50 to the outside.

FIG. 7 shows how the moisture-proof building material 1 is attached to the ceiling 55.

The attachment of the moisture-proof building material 1 to the ceiling 55 is performed by attaching the moisture-proof building material 1 to each grid unit of the ridge 47 or to a plurality of grid units.

Specifically, in the present embodiment, as shown in FIG. 8, first, one of the moisture-proof building materials 1 (for example, located at the leftmost side in FIG. The edge of the gypsum board 2 is stuck to the bezel 47 by nailing or the like with the surface of the moisture-proof building material) facing the vinyl sheet 3 facing the bezel 47 side.

Then, the moisture-proof building material 1 to be subsequently attached to the protruding portions 33, 34 of the moisture-proof building material 1 attached thereto.
Edges of the gypsum board 2 on which the edges of
1 and 22 are brought into contact with the edges of the gypsum boards 2 already applied, so that these gypsum boards 2
7 is attached by nailing or the like.

That is, the moisture-proof building material 1 already attached
The protruding portions 33 and 34 and the edges of the vinyl sheets 3 and 3 of the moisture-proof building material 1 adjacent to the moisture-proof building material 1 overlap at a field edge 47, and the overlapped portion is formed by nailing the gypsum board 2 or the like. A plurality of moisture-proof building materials 1 are sequentially attached to each lattice so as to be pressed against 47.

Since the protruding portions 33 and 34 of the moisture-proof building material 1 located on the rightmost side and the innermost side in FIG. 7 are left behind, do not fold and conceal them below the edge 47 as shown in FIG. Or cut out.

By attaching a plurality of moisture-proof building materials 1 to the ceiling as described above, the entire lattice-shaped ridge 47 of the ceiling is air-tightly covered with the plurality of vinyl sheets 3.

Therefore, the indoor humidity is completely shut off by the vinyl sheet 3, so that the moisture does not enter the wooden part such as the field margin 47 and adhere to the wooden part, and the warm air from the indoor flows from the ceiling part 55 to the outside. Never escape.

As described above, the moisture-proof structure of the present embodiment uses the moisture-proof building material 1 in which the gypsum board 2 as the face material and the vinyl sheet 3 as the moisture-proof material are formed integrally with the wall panel 43.
Since it is a structure to be attached to the ridge 47 of the ceiling portion 55 or the ceiling portion 55, if the gypsum board 2 is attached by nailing or the like, the vinyl sheet 3 is inevitably attached, as in the conventional example shown in FIGS. This eliminates the need for separately attaching the vinyl sheet 3 and the gypsum board 2 at the construction site. As a result, labor saving at the construction site can be achieved, and complete dampproofing can be achieved in a cold-area house.

[0045]

As described above, in the moisture-proof structure of the present invention, since the moisture-proof building material in which the surface material and the moisture-proof material are integrated is attached at the construction site, the surface is inevitably applied only by the work of attaching the moisture-proof building material. Since the material and the moisture-proof material are attached, labor saving of on-site work can be achieved.

Further, a plurality of moisture-proof building materials are sequentially arranged along the joining direction of the face materials so that the moisture-proof material of the moisture-proof building material adjacent to the wall portion of the building overlaps the protrusion of the moisture-proof material of the one moisture-proof building material. As a result, the wall panels are completely covered with a single piece of moisture-proof material, so that moisture does not enter the gaps between the wall panels, making it possible to achieve complete dampproofing of the house. There is. Here, in caulking
The moisture-proof material of the moisture-proof building material to be installed first does not protrude
Because it can suppress the moisture that enters from the side part,
Moisture proof can be ensured. Further, since the moisture-proof material is not exposed to the indoor side and no special treatment for hiding the moisture-proof material is required, labor at the construction site can be saved. Since the protruding portions of the moisture-proof material do not overlap with each other, the connection of the moisture-proof building material is easy, and the work of attaching the moisture-proof building material can be performed quickly and accurately. In addition, since the surface material of the moisture-proof building material has a width substantially equal to the wall panel to which the moisture-proof building material is attached, the inner wall surface of the wall formed using the wall panel can be covered without excess or shortage, and the width of the wall portion can be improved. It is not necessary to perform cutting or the like on site to adjust to. Therefore, it is possible to construct an efficient and highly reliable moisture-proof structure.
