Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a direct foundation which is an important component of a building, and more particularly to a direct foundation formed of concrete.

[0002]

2. Description of the Related Art A direct foundation for a building is an important structure for a building because it directly transfers the load from the superstructure of the building to the ground to support the building and prevent adverse effects from the ground. Of course, it is an element. Since such an important direct foundation is in direct contact with the ground, it is likely to be adversely affected by generation of mold (mainly decay fungi) due to moisture from the ground or pests.

In order to prevent such an adverse effect of the direct foundation, various studies have been made so far, but a typical method thereof is to form the direct foundation by concrete. In this way, the direct foundation itself is almost adequately protected against mold and pests.
However, pests such as termites can also pierce such concrete and invade into and overwhelm the superstructure of buildings with many woody parts, and also directly lay the foundation. Depending on the situation, molds that adversely affect the superstructure may reach the top through this direct foundation. In other words, even if the direct foundation was made of concrete, the superstructure of the building could not be reliably protected in some cases.

As a conventional antiseptic / insect repellent treatment especially for a solid foundation, a method of applying an antiseptic treatment or an insect repellent treatment by laying a sheet on the whole surface, or applying an antiseptic agent or an insect repellent to the sheet itself is applied. Methods such as preservative treatment or insect repellent treatment are also under study. However, not only is it difficult to cover the surface of a solid foundation with such a sheet, but a gap is inevitably formed between this sheet and the solid foundation, and termites and mold enter the superstructure side through this gap. It is possible to do so. In other words, even if a direct foundation such as a solid foundation was made of concrete and a sheet was laid on it, the superstructure of the building could not be reliably protected in some cases.

Therefore, the present inventor has made various studies on how to directly protect the foundation itself from mold and pests and also to sufficiently protect the upper structure of the building located above it. As a result, the present invention has been completed.

[0006]

SUMMARY OF THE INVENTION The present invention has been made based on the above circumstances, and the problem to be solved is to ensure that a direct foundation made of concrete for a building is subjected to antiseptic or insect repellent treatment. To apply to.

An object of the present invention is to provide a direct foundation with a simple structure capable of reliably protecting itself and a superstructure of a building located above it from mold and pests.

[0008]

In order to solve the above problems, the means adopted by the invention according to the first aspect is
The description will be given with the reference numerals used in the examples. “In the building 20 in which the cloth foundation 11 and the solid foundation 12 formed therebetween are formed of concrete,
0.01% to 10% of at least one of the preservative or insect repellent is applied to at least one of the cloth foundation 11 and the solid foundation 12.
A direct foundation 10 "for a building 20, characterized in that it is formed by a% mixed concrete.

That is, in the direct foundation 10 for the building 20, the cloth foundation 11 and the solid foundation 12 are made of concrete, and the following preservative or insect repellent is mixed in the concrete material. Therefore, either the cloth foundation 11 or the solid foundation 12 is subjected to antiseptic / insect repellent treatment.

Various kinds of preservatives or insect repellents can be applied. In the present invention, the following water-soluble, oil-soluble or oily substances are appropriately selected and used.

(1) Water-soluble preservative or insect repellent: boron-based, chromium / copper / arsenic compound-based, phenolic inorganic / fluoride-based, alkylammonium compound, benzothiazole-based, acidic copper chromate-based, ammoniacal Copper arsenate, Chromated zinc arsenate, Chromated zinc chloride.

(2) Oil-soluble preservative or insect repellent Organic tin-based, naphthenic acid metal salt, chlornaphthalene-based,
Organic iodine type, pyrethroid type, bromide type, chlorobenzene type, carbamate type, organic phosphorus type, organic chlorine type, kepon type, carbonate type, phenols (chlorophenol type, bromphenol type, nitrophenol type),
Quinolines, cyclofluamides, TPIC, S-42
1, xylazane aluminum salt, flutolanil.

(3) Oily preservative or insect repellent creosote oil.

Of the above preservatives or insect repellents, oil-soluble or oily ones are difficult to mix into fresh concrete as they are, but a surfactant or the like is used before mixing. It may be used by emulsifying it or enclosing it in microcapsules. Such preservatives or insect repellents are
It is necessary to mix the concrete material in the range of 0.01% to 10%. The reason is 0.01%
This is because if the amount is less, the antiseptic / insect repellent effect is not sufficient, while if it is more than 10%, not only does the substantial antiseptic / insect repellent effect remain unchanged, but it may cause phytotoxicity. .. Above all, the mixing ratio of this preservative or insect repellent with respect to the concrete material is most effective and economical in the range of 0.1% to 3%.

Of course, one of these preservatives or insect repellents may be used alone or both of them may be used at the same time. The selection is made in consideration of the site conditions of the building and the like. All you have to do is go.

The preservative or insect repellent as described above may be applied or sprayed directly on the surface of the cloth foundation 11 or the direct foundation 10 of the solid foundation 12, which is defined in claim 2. This is the direct foundation 10.
The application or spraying of such an antiseptic or insect repellent is performed by the direct foundation 1 such as the cloth foundation 11 or the solid foundation 12.
It may be performed after 0 is formed by concrete, and spraying has the best workability.

As described above, claim 1 or claim 2
In any of the direct foundations 10 above, since the preservative or insect repellent is present on the entire surface thereof, the harmful insects and molds which try to enter the superstructure side of the building are prevented. In particular, the direct foundation 10 according to claim 1
In this case, since an antiseptic or an insect repellent is also mixed in the inside, even if the base 10 is directly cracked, no pests or molds can enter through the cracks. Further, in the direct foundation 10 according to claim 1, since the insect repellent is mixed inside as described above, it is a pest capable of making a hole in the concrete itself, such as a termite. Even if it does, it cannot reach the superstructure side of the building.

Therefore, the direct basis 1 according to any claim
Even if it is 0, the preservative or insect repellent prevents the invasion of mold and harmful insects into the superstructure side,
The direct foundation 10 as well as the superstructure of the building above it is surely protected.
