Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidity control building material used as an interior wall material or a ceiling material in a building such as a building or a general house, and a building wall structure having an air layer between an outer wall and an inner wall. More specifically, the present invention relates to a humidifying building material that exhibits a humidifying function using diatomaceous earth, and a building wall structure that prevents dew formation in an air layer.

[0002]

2. Description of the Related Art In buildings such as houses, interior materials made of wood and the like have been used as interior materials for rooms and the like. Such an interior material made of wood or the like has a function of absorbing and releasing moisture in the air and releasing the absorbed moisture into the air, and adjusts the indoor humidity to a substantially constant humidity. However, in recent years, it has been difficult to use an interior material having a moisture absorption / release function such as wood due to demands for high airtightness, high heat insulation, non-combustibility, and the like, and the interior material cannot be expected to have a moisture absorption / release function. For this reason, not only dew condensation and the like occur in the room, but also mold and mites are generated, which is one of the causes of impairing the feeling of living.

[0003] Therefore, various building materials such as panels having a function of absorbing and releasing moisture have been developed.
No. 895 is known. In Japanese Patent Application Laid-Open No. 9-85895, a foamed ceramic molded plate in which ceramic fine hollow particles are joined with a melt of a ceramic or ceramic composition is used as a front and back surface material, and a core material is filled with a humidity control material. A lightweight humidity control panel with a honeycomb or corrugated structure is described.

[0004]

However, in the lightweight humidity control panel described in Japanese Patent Application Laid-Open No. 9-85895, since both sides are made of foamed ceramic, the texture is limited and the degree of freedom in design is limited. And its use is limited, and the production is difficult and expensive. The present invention has been made in view of the above problems, and an object of the present invention is to provide a humidity control building material that can be designed at a high degree of freedom and can be manufactured at low cost, and further provide a building wall structure and a room interior structure. .

[0005]

In order to achieve the above object, a humidity control building material according to the first aspect of the present invention comprises a supporting material having a honeycomb structure or a corrugated structure filled with a humidity control material containing at least diatomaceous earth. It was sandwiched between a rigid material and a moisture permeable material.

According to a second aspect of the present invention, there is provided a humidity control building material, wherein a supporting material having a honeycomb structure or a corrugated structure filled with a humidity control material containing at least diatomaceous earth is arranged in a frame of a frame material. An impermeable material was fixed on one surface of the material, and a moisture permeable material was fixed on the other surface of the frame material.

[0007] Further, the humidity control building material according to the third aspect of the present invention is a humidity control material including a support member having a plurality of recesses formed therein, and a humidity control material containing at least diatomaceous earth filled in the recesses of the support material. And a moisture-permeable material fixed to the surface of the support material on the concave opening side.

Still further, according to a fourth aspect of the present invention, in a building wall structure in which an air layer is defined between an outer wall and an inner wall, a humidity control material is provided inside at least one of the outer wall and the inner wall. The humidity control building material was provided so as to be exposed to the air layer.

According to a fifth aspect of the present invention, there is provided the humidity control building material according to any one of the first to third aspects and the building wall structure according to the fourth aspect, wherein the humidifying material is diatomaceous earth alone, diatomaceous earth and a ceramic raw material. Or a composite containing diatomaceous earth as a filler. This humidifier is preferably
The diatomaceous earth uses Wakkanai diatomite shale, and if necessary, diatomaceous earth is gradually coarsely crushed to finely crushed, sieved to obtain a particle having a particle size of about 1 μm, mixed with a powder of ceramic or the like, and then 1 mm to 3 mm. It is formed into granules having a particle size of a certain degree or a desired shape.

[0010]

According to the first aspect of the present invention, the moisture-control building material sandwiches the supporting material between the moisture-permeable material and the rigid material, and the moisture-conditioning building material according to the second aspect holds the supporting material on the frame material (or the frame material and the water-impermeable material). To provide a moisture permeable material to the frame material,
The humidity control building material according to claim 3 holds the humidity control material in the support material and provides the moisture control material on the opening side of the concave portion of the support material, so that moisture is adsorbed through the humidity control material in the support material, and In addition, the moisture of the humidity control material is released via the moisture permeable material, and the humidity of the space to which the humidity control material is exposed is adjusted. And since the moisture permeable material can be composed of paper, nonwoven fabric, etc., a great degree of freedom in design is obtained,
In addition, it is easy to manufacture, and can be manufactured at low cost.

According to the fourth aspect of the present invention, since the humidity of the air layer between the outer wall and the inner wall is adjusted by the humidity control building material, dew condensation can be prevented at low cost. That is, in the conventional building wall structure, a positive ventilation structure that opens the air layer to the atmosphere, or an active ventilation structure that further includes a forced ventilation mechanism such as a fan is employed to prevent dew condensation on the air layer wall surface, In the former positive ventilation structure, condensation cannot be sufficiently prevented, and in the latter active ventilation structure, not only initial costs but also running costs increase, so by using the building wall structure of the present invention together,
Since at least a part of the air layer is defined by the humidity control building material, dew condensation can be reliably prevented without increasing the cost.
