At the same time, the fixing piece 9 is fixed to the surface of the pillar 10, and the grooved strip 7
This relates to an air cycle house in which the space surrounded by the board and the board 8 is accommodated as an air cycle space.

An air cycle house is a space with a thickness of, for example, 10 to 20 m between the inner wall 1 and outer wall 2 of the building, which is used as an air cycle space 3. In the winter, the heat stored in the attic space 4 is passed through the air cycle space 3 to keep the inside of the wall warm, and warm air is guided to the underfloor space 5 to keep the underfloor warm.In the summer, the cold air in the underfloor space is transferred to the air. While cooling the inside of the wall through the cycle space 3, it is raised to the attic space 4 and only hot air is released.

FIG. 1 shows the state of the air cycle in winter, when the ventilation opening A under the floor and the ventilation opening B in the attic are closed.

In Figure 1, C indicates a heating device such as a stove, A, indicated by the thick arrow in Figure 1, indicates solar heat, and the opening indicated by the thick arrow indicates north wind, as indicated by the thin arrow in Figure 1. air is allowed to circulate.

FIG. 2 shows the state of the air cycle in the summer, in which the ventilation opening A under the floor and the ventilation opening B in the attic are open.

In a cooling device such as a D&X cooler in Fig. 2, the thick arrow C in Fig. 2 indicates outside air, and the air flows as shown by the thin arrow in Fig. 2.

By the way, in the above-mentioned air cycle house, when glass wool is filled between the inner wall 1 and the outer wall 2 as a heat insulating material, when the humid air under the floor circulates and passes through the wall, the humid air is absorbed by the glass wool. There is a problem in that moisture enters the glass wool, degrading its inherent insulation properties, and condensation occurs inside the walls.Furthermore, in air cycle houses, air cycle spaces are installed inside the walls. Although the purpose is to connect the attic space 4 and the underfloor space 5 to circulate air, filling the space between the outer wall 2 and the inner wall 1 with glass wool blocks the air flow. However, air cycle houses are now becoming unsuitable as air cycle systems, and now air cycle houses are being developed that do not reduce the insulation properties due to condensation, etc. even if insulation is placed inside the walls, and do not block the air flow. desired.

The purpose of this invention is to attach a board to the heat insulating board and create an air cycle space in the space surrounded by the grooves and the board, allowing for smooth air flow and making the heat insulating board independent. Since it is made of synthetic resin foam with a foam structure, moisture does not get inside and the insulation properties do not deteriorate.Furthermore, the width of the board is wider than the insulation board, and both ends of the board are fixed pieces, so the insulation is improved. When installing the board, you can easily install the heat insulating board by fixing the fixing pieces to the pillars.In addition, by providing a lath on the surface of the board (this allows the board to be used as a base for the exterior wall, and the lath also To provide an air cycle house which can be constructed simultaneously and is easy to construct.

The present invention will be explained in detail below using examples.

Reference numeral 6 in the figure is a heat insulating board made of synthetic resin foam with a closed cell structure such as polyethylene, polystyrene, polyvinyl chloride, etc. The surface of this heat insulating board 6 is provided with multiple rows of grooves 7 extending vertically. be.

A plate material 8 wider than the heat insulating board 6 is attached to the surface of the heat insulating board 60 with an adhesive, and portions of this board material 8 that protrude from both ends of the heat insulating board 6 serve as fixing pieces 9.

The board material 8 may be, for example, a wooden board, a wood cement board,
Wood fiber cement board 2 A board-like material such as gypsum board is used, and a felt lath paper 12 is pasted on the surface of this board material 8, and a lath 11 like a wire mesh is attached to the surface of the lath paper 12. It is ge.

Here, the width of the heat insulating board 6 is approximately equal to the distance between the pillars 10 of the air cycle house, for example, 450 fi, and the protruding length of the fixed piece 9 is approximately - the width of the pillars 10. Further, the thickness of the heat insulating plate 6 is approximately equal to the width of the pillar 10.

Thus, the heat insulating plates 6 are fitted between the columns 10, and the fixing pieces 9 are applied to the surfaces of the columns 10 and fixed by nailing or the like.

In this case, the board material 8 is used as the base of the outer wall, and the board material 8
The outer wall 2 is formed by applying mortar 13 on the lath 11 of the 0 surface for finishing.

Here, the space surrounded by the groove 1 and the plate material 8 becomes an air cycle space 3, and this air cycle space 3 communicates with the attic space 4 and the underfloor space 5, and is an air cycle space. 3 through which air circulates between the attic space 4 and the underfloor space 5.

In the figure, 1 is the inner wall.

In the present invention, as described above, a plate material is attached to the heat insulating board and the space surrounded by the groove and the board material is used as an air cycle space, so the heat insulating board is placed between the inner wall and the outer wall. This allows for smooth air flow, which prevents condensation from forming inside the walls, and allows air to circulate between the attic space and the underfloor space, resulting in a good air cycle effect. Furthermore, since the insulation board is made of synthetic resin foam with a closed cell structure, moisture does not enter inside and the insulation effect does not deteriorate.Furthermore, the width of the board is made wider than the insulation board. Since both ends are fixed pieces and these fixed pieces are fixed to the surface of the pillar, the insulation plate with air cycle space can be installed by simply inserting the insulation board between the pillars and fixing the fixed piece to the pillar, making installation easy. It has the advantage of being able to be used as a material, and since it is made of plate material, it does not deform even when subjected to external force.
It's something that won't break.

Furthermore, since the board material has a lath on its surface, the lathed board material attached to the insulation board can be used as the base for the exterior wall, and there is no need for a separate base for the exterior wall, and mortar can be applied directly onto the lath. The outer wall can be formed by using the lathed board material, which is a part of forming the air cycle space and also a part of fixing the insulation board to the pillar, as the base of the outer wall. It is possible to create an air cycle house with a simple structure and a small number of parts.
