Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete building, and more particularly to a concrete building structure suitable for use as a building for displaying works of art or a clean room.

[0002]

2. Description of the Related Art Alkali harmful substances such as ammonia are generated from concrete, which is a material for constructing a building, and are taken into the air to generate an alkaline atmosphere. It has been confirmed that the most occurrences occur after the completion of construction, and when this concrete building is used as a museum as it is, the artworks exhibited in the room are exposed to the alkaline atmosphere and deteriorate or deteriorate. There was a problem that caused it. Therefore, the air conditioner of the building is equipped with an adsorption filter using activated carbon or zeolite to remove the alkaline substance in the atmosphere of the indoor space.

[0003]

However, there is a considerable distance from the interior surface of a concrete building to the air conditioner with an adsorption filter, and the alkaline atmosphere from the interior surface is displayed in the room on the way to the air conditioner. There is a problem that it may come into contact with the existing artwork and affect it. In addition, in the fields of electronics, precision equipment, biotechnology, etc., it is more suitable for industrial clean rooms where semiconductor manufacturing, precision machine assembly, etc. are performed, or bio clean rooms where hospitals or microorganism / tissue culture experiments are conducted. High cleanliness is required. Therefore, there has been a demand for preventing the generation of an alkaline atmosphere due to the concrete of the building in these clean rooms.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a concrete building structure capable of preventing the generation of an alkaline atmosphere in the indoor space of a concrete building.

[0005]

In order to achieve the above-mentioned object, a concrete building structure according to the present invention has an interior surface of a concrete building that defines an interior space and an interior material attached to the interior surface. And an adsorbent for shielding an alkaline substance generated from concrete between the interior space and the interior space.

The adsorbent is a sheet-shaped or felt-shaped member containing activated carbon or zeolite.

[0007]

The operation of the present invention will be described. Between the interior surface of a concrete building that defines the interior space and the interior material attached to the interior surface, an alkaline substance generated from concrete is injected into the interior space. By providing the adsorbent for shielding, the alkaline substance generated in the concrete comes into contact with the adsorbent and is adsorbed and removed before the alkaline atmosphere is generated in the indoor space. Therefore, even if an alkaline substance such as ammonia is generated from the concrete after the building is completed, it is possible to prevent the alkaline atmosphere from being generated in the indoor space.

Further, since the adsorbent contains activated carbon or zeolite, an alkaline substance such as ammonia is sufficiently adsorbed, and the adsorbent is a sheet-like or felt-like member, so that the interior surface and the interior material are Can be easily arranged between the two.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a vertical sectional view showing a preferred embodiment of a concrete building structure according to the present invention. An adsorbent 12 for shielding an alkaline substance generated from concrete is provided between the interior surface 6 of the reinforcing steel or steel-concrete concrete building 2 that forms the interior space 4 and the interior material attached to the interior surface 6. It is provided.

Alkaline substances, in this case mostly ammonia, are released from the concrete surface. It is considered that an alkaline atmosphere is generated in the indoor space 4 due to the fact that this ammonia is taken into the moisture in the air.

The adsorbent 12 is formed by containing activated carbon or zeolite. The activated carbon is a carbonaceous substance having a strong adsorptivity as is well known, and is usually powdery or granular. Zeolite is a zeolite and has an ion exchange property and has a strong adsorptivity similar to activated carbon. Further, since the adsorbent 12 is a sheet-shaped or felt-shaped member, it is not only easy to process such as cutting, but also can be easily fixed to a mounting plane by a method such as adhesion, so that workability is improved. It is good.

A plaster board 8 is provided as an interior material on the ceiling surface or the wall surface, and a floor material 10 is provided on the floor surface. An adsorbent material 12 is previously fixed to the back surface of the plaster board 8 or the floor material 10 by a method such as adhesion before being arranged.

Then, between the interior surface 6 of the concrete building 2 which defines the interior space 4 and the interior material attached to the interior surface 6, the interior space 4 is shielded from alkaline substances generated from concrete. Adsorbent 12 to do
By providing the above, the alkaline substance generated in the concrete comes into contact with the adsorbent 12 and is adsorbed and removed before the alkaline atmosphere is generated in the indoor space 4. Therefore, even if an alkaline substance such as ammonia is generated from the concrete after the building is completed, it is possible to prevent the alkaline atmosphere from being generated in the indoor space 4.

Further, since the adsorbent 12 is arranged so as to be in contact with the indoor surface 6, even if the alkaline atmosphere is generated from the concrete, the alkaline substance is immediately adsorbed to the adsorbent as it is. , Can be efficiently removed, and diffusion to the surroundings is surely prevented. Therefore, even if an alkaline substance is generated from concrete, it is possible to prevent an alkaline atmosphere from being generated in the indoor space 4. Therefore, even if a work of art is displayed in the indoor space 4 immediately after the completion of construction, alkaline substances such as ammonia will not be generated. It does not promote the deterioration or deterioration of works of art. Then, even a concrete building can be sufficiently used as an art museum or the like. Further, compared to the conventional case where an adsorbing device such as a filter is provided in the air conditioner to remove the alkaline substance, the work of art is not exposed to the alkaline atmosphere between the concrete and the air conditioner. On the other hand, since it is possible to almost prevent the generation of an alkaline atmosphere, it is possible to reduce the number of adsorbing members of the air conditioner, and it is possible to reduce the transportation power of the air conditioner and the pressure loss. It is possible. In addition, by adopting the same structure in a concrete clean room where semiconductor manufacturing, precision machine assembly, etc. are carried out, or a hospital or a bio clean room where microorganisms / tissue culture experiments are carried out, etc. ,
It is possible to prevent an alkaline atmosphere from being generated in the clean room. Therefore, a clean space that is not affected by the alkaline atmosphere can be formed.

Further, since the adsorbent 12 contains activated carbon or zeolite, an alkaline substance such as ammonia is sufficiently adsorbed, and the adsorbent 12 is a sheet-shaped or felt-shaped member, so that its workability is improved. Plasterboard 8 which is an interior material because of its goodness
The interior surface 6
And the plasterboard 8 and the flooring material 10 which are interior materials. Therefore, the alkaline substance such as ammonia can be removed efficiently, and the installation can be done easily without any trouble.

[0016]

According to the present invention, an alkaline substance generated from concrete is shielded from the interior space between the interior surface of a concrete building defining an interior space and the interior material attached to the interior surface. By providing the adsorbent for this purpose, even if an alkaline substance is generated in concrete, it is adsorbed and removed by the adsorbent, so that it is possible to prevent an alkaline atmosphere from being generated in the indoor space.

Further, since the adsorbent is a sheet-like or felt-like member containing activated carbon or zeolite, alkaline substances such as ammonia can be efficiently removed, and the installation can be done easily and without any trouble. .
