Further, the moisture-permeable waterproof sheet 11 or the waterproof sheet 14 can prevent rainwater or the like from entering the room.

FIG. 4 is a schematic view of a building sheet in which a core material, a filter and a moisture-permeable waterproof sheet or a waterproof sheet are integrated. FIG. 4 (a) is a building sheet 3a in which a filter 13 is attached to one side of a core material 12 and a moisture-permeable waterproof sheet 11 or a waterproof sheet 14 is attached to the other side of the core material 12 to be integrated, and FIG. Is a building sheet 3b in which the filter 13 and the moisture-permeable waterproof sheet 11 or the waterproof sheet 14 are attached to one side of the core material 12 so as to be integrated. As a method of integrating the same, the same method as that of attaching the filter 13 or the moisture-permeable waterproof sheet 11 and the waterproof sheet 14 to the core material 12 described above can be used.

The building sheet 3a shown in FIG. 4 (a) is used, for example, for mortar wall construction in which a tacker nail is directly attached to the underlaying material of the wall, a lath is further applied thereon, and mortar coating is applied. You can A space (ventilation layer) can be formed in the wall by the high compressive strength of the core material 12 included in the building sheet 3a in one step of attaching the building sheet 3a with a tacker nail. In addition, the filter 13
Prevents the mortar from entering the core material 12, and allows moisture from the wall body to pass through the moisture permeable waterproof sheet 11 to the core material 1
2 can be dehumidified. Further, the moisture-permeable waterproof sheet 11
Instead of this, by integrating the waterproof sheet 14, it is possible to completely prevent the intrusion of water from the outside, and it is also possible to use it in a place that does not require moisture permeability.

The building sheet 3b shown in FIG. 4 (b), like the building sheets 2a and 2b shown in FIG. 3, can be directly attached to the underlaying material of the wall or the base material of the roof with a tacker nail. . Since the filter 13 also plays a role of reinforcing the compressive strength of the core material 12, the building sheet 3b thus integrated is used for attaching to the underlaying material of the wall using tucker nails or the base material of the roof. Can be a material that can withstand enough. Further, since the filter 13 has air permeability, the core material 12 and the moisture-permeable waterproof sheet 11 or the waterproof sheet 1 are used.
Since the core material 12 is positioned between the core material 12 and the core 4, the function of moisture removal / ventilation in multiple directions performed through the hollow structure of the core material 12 can be further enhanced.

The construction sheet of the present invention is not limited to the structure shown in FIG. 4 when it includes the filter 13 and the moisture-permeable waterproof sheet 11 or the waterproof sheet 14, and for example, the filter 13 is made of the core material 12. The structure may be such that it is attached to both sides and the moisture-permeable waterproof sheet 11 or the waterproof sheet 14 is further attached to one side thereof. When the filter 13 and the moisture-permeable waterproof sheet 11 or the waterproof sheet 14 are attached to the same side of the core material 12, either one may be on the outside. In any configuration, a space for ventilation and dehumidification (ventilation layer) is formed in one step of attaching the building sheet to the underlaying material of the wall or the base material of the roof using tacker nails. You can

The building of the present invention is one in which any of the above-mentioned building sheets is attached to a base material in at least construction of any of roof, wall and floor. Some examples are shown below. FIG. 5 is a schematic view showing the structure of the wall of the building, FIG. 5 (a) is a structure of the conventional outer wall ventilation method, and FIG. 5 (b) is a schematic showing the structure of the wall of the building of the present invention. It is a figure. 6 is a schematic view showing the structure of the wall of the building, FIG. 6 (a) is the structure of the conventional general mortar outer wall ventilation method, and FIG. 6 (b) is the structure of the building of the present invention. It is the schematic which shows the structure of a wall. The construction of the conventional outer wall ventilation method is
For example, as shown in FIG. 5 (a), a moisture-permeable waterproof sheet 11 is put on a subbing material 22 of a wall 20 of a building, and a paulownia edge 2 is placed on the waterproof sheet 11.
The outer wall material 23 is stretched by nailing 4 with nails at intervals of the studs 21b, but when the outer wall material 23 is thin, warpage occurs as the years go by. Furthermore, the space (ventilation layer) 25 of the wall 20 of the building
In the inside, the moisture-permeable waterproof sheet 11 sags due to heat and is shaken by the wind entering through the gap, and adheres to the back surface of the outer wall member 23 with water droplets coming from dew condensation, thereby significantly reducing its function. Further, if the thickness of the paulownia border 24 is increased and the space (ventilation layer) 25 is increased to prevent adhesion, air convection occurs in the space (ventilation layer) 25, and the heat insulating effect is reduced.

However, as shown in FIG.
In the architectural sheet 2a of the present invention, the core material 12 and the moisture-permeable waterproof sheet 11 are integrated, and the core material 12 has a hollow structure. Therefore, the space for ventilation (ventilation layer) 25
At the same time, the core material 12 prevents adhesion between the moisture-permeable waterproof sheet 11 and the outer wall material 23. Therefore, unlike the conventional case, the paulownia edge 24 for providing the space (ventilation layer) 25 for ventilation is not required, and the construction sheet 2a is simply attached to the outer wall subbing material 22 directly with a tacker nail. Since the construction can be done in one step, the process can be remarkably simplified, the construction period can be shortened and the cost can be reduced.
Further, since the core material 12 has a three-dimensional structure and high compressive strength, the outer wall material 23 can be stretched directly on the core material 12. Further, the core material 12 has a hollow structure,
Air and moisture can move in all directions. As a result, moisture inside the wall 20 of the building or rainwater or water that has entered from the outside does not stay through the core material 12,
Moisture, ventilation, and drainage can be performed outside, and the durability of the building can be increased. Although FIG. 5B shows an example using the building sheet 2a, the building sheet 1
And the moisture-permeable waterproof sheet 11 can be used together, and the building sheet 3b including the moisture-permeable waterproof sheet can also be used.

Further, as shown in FIG. 6 (a), in the conventional mortar wall ventilation method, it is necessary to provide a paulownia edge 24 on the subbing material 22 and to further provide a double subbing material 22. Yes, it was too expensive. However, according to the present invention, as shown in FIG. 6 (b), the building sheet 3 a
A space (ventilation layer) 25 for ventilation can be formed by a single one-step construction in which the underlayer 22 is directly stretched with a tacker nail. Since the filter 13 can prevent the mortar, which is the outer wall material 23, from entering, the building sheet 3
A mortar can be applied by placing a lath on a. In this way, the construction can be greatly simplified, the construction period can be shortened and the cost can be saved. Although FIG. 6B shows an example in which the building sheet 3a is used, the building sheet 1
And the moisture-permeable waterproof sheet 11 or the waterproof sheet 14 may be used together.

FIG. 7 is a schematic view showing a structure of a roof 30 of a building, FIG. 7 (a) shows a conventional general tile roof structure, and FIG. 7 (b) shows a structure of the building of the present invention. It is the schematic which shows the structure of a tiled roof. A conventional thatched roof 30 is shown in FIG.
As shown in FIG. 3, the waterproof sheet 14 is attached to the base material 33, the sprue 32 is struck on the waterproof sheet 14, and the roof tile 31 is stretched. For this reason, the rainwater invaded by the piers 32 is dammed up and stays there, which damages the roofing material over time, which in turn causes rain leakage in the building. However, according to the present invention, as shown in FIG. 7 (b), the construction sheet 2 a may be attached to the base material 33, the sprue 32 may be struck on the construction sheet 2 a, and the roof tile 31 may be attached. . Since the core material 12 included in the building sheet 2a has a high pressure resistance, even if the sprue 32 is directly struck on the core material 12 and the roof tile 31 is stretched, the core material 12 maintains a hollow structure and has a space for ventilation ( A ventilation layer) can be formed. With such a configuration, rainwater that has entered through the gap between the tiled roofs is drained through this space and does not stay there. Further, in the hollow structure of the core material 12, since there is no partition, air is ventilated in all directions, so the effect of moisture removal and ventilation is great. This makes it possible to enhance the durability of the building without damaging the roofing material over time. Although FIG. 7B shows an example using the building sheet 2a, the building sheet 1 and the waterproof sheet 1 are shown.
4 can be used together, and the building sheet 3b including a waterproof sheet can also be used.

FIG. 8 is a schematic view showing the structure of a roof 30 of a building, and FIG. 8 (a) shows a structure of a conventional general decorative slate roof with a ventilation method, and FIG. 8 (b). FIG. 1 is a schematic view showing the structure of a decorative slate thatched roof of the building of the present invention. In the case of the conventional ventilation method for a decorative slate thatched roof, as shown in FIG. 8 (a), rafters 34 are nailed on the base material 33 at regular intervals, and the base material 33 is stretched on the rafters 34 to form a space ( A ventilation layer 25 is provided, the waterproof sheet 14 is placed on the ventilation layer 25, and the decorative slate roofing material 31-A is used for finishing. With such a configuration, a space (ventilation layer) 25 that can be ventilated can be secured, but since the formed space (ventilation layer) 25 is also partitioned by the rafters 34, ventilation is limited to one direction, and the exhaustion and ventilation are limited. The effect of is reduced. However, according to the present invention, as shown in FIG. 8 (b), the rafter 34 and the base material 33 may be a single set, and the construction sheet 3 b is stretched over the base material 33 to make a makeup slate roofing. The roof material 31-A may be used for finishing. Since the core material 12 included in the building sheet 3b has high compressive strength, the direct decorative slate roofing material 3 is used.
Even if 1-A is stretched, the hollow structure can be maintained and a space (ventilation layer) 25 for ventilation can be formed. This can completely prevent dew condensation on the back surface of the decorative slate roofing material 31-A. Further, the core material 12
With the hollow structure, there is no partition, and since it ventilates in all directions, the effect of moisture removal and ventilation is great. Further, the construction of the conventional roof by the ventilation method can be remarkably simplified, and the construction period and cost can be reduced. Furthermore, the durability of the obtained building can be improved. Although FIG. 8B shows an example using the building sheet 3b, the building sheet 2b can also be used, and the building sheet 1 can be used.
And the waterproof sheet 14 can be used together.

The building sheet of the present invention can be used for walls, roofs and floors of condominiums and commercial buildings. In particular, it can be used by laying under a closet for facilitating dehumidification, or can be used in a veranda garden or the like that requires drainage. In addition, it can be laid under soil such as gardens and farms provided indoors and outdoors, and finished concrete such as basements, underground parking lots and paved roads, and can be used for construction to improve drainage. Furthermore, by using the building sheet of the present invention, it is possible to shorten the construction process and period as compared with the conventional case.

The building method of the present invention is to construct a building using any of the above-mentioned building sheets. As already described by way of example, the method has a step of attaching one of the construction sheets to a base material for a roof, a wall, a floor lining material, and the like. Here, for example, the construction sheet 2b in which the waterproof sheet 14 and the core material 12 are integrated may be attached to a location requiring waterproofness, or the filter 13 and the core material 12 may be integrated. The waterproof sheet 14 may be stretched after the reduced construction sheet 1 is stretched. Any of the building sheets of the present invention can be appropriately used according to the ease of construction. By such a construction method of the present invention, the steps required for the conventional ventilation method can be significantly simplified,
The construction period can be shortened and the cost can be reduced.
