BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a basic structure of a building for preventing damage such as termites.

[0002]

It is known that copper patina can be used as an insecticide. Copper reacts with carbon dioxide and water to change to patina. A structure has been developed that uses an insecticidal action of patina to make an electric wire an insect-proof structure or to prevent the building foundation from being damaged by termites. For example, actual fair 4-2137
Japanese Patent Publication No. 2 describes a technique for preventing a termite from being damaged by sandwiching a copper-based metal plate between a building foundation and a base.
The insect repellent structure described in this publication has both sides of a copper-based metal plate folded back and sandwiched between a foundation and a base. The basis of this structure is to kill termites or prevent them from entering the base due to the toxicity of the patina generated from copper-based metal plates.

[0003]

The basic structure of a building of this structure has the feature that the base can be prevented from being damaged by termites for an extremely long period of time due to the patina in which the copper-based metal plate changes. However, the copper-based metal plate processed in this way is
It has the drawback of being difficult to install between the foundation and the base. This is because after fixing the copper-based metal plate to the foundation, the base on it is fixed. When the copper-based metal plate is fixed to the foundation by this method, it is necessary to form a through hole in the copper-based metal plate in accordance with the position of the anchor bolt of the foundation. If the positions of the through holes are misaligned, the copper-based metal plate cannot be attached at the correct position on the foundation, and the copper-based metal plate projects from the side surface of the base or is located inside the base. If the copper-based metal plate projects from the base, it becomes an obstacle. For this reason, it is necessary to form the through holes in the copper-based metal plate with extremely high accuracy, and this work has a drawback that the work is troublesome.

Further, as described above, the structure in which the copper-based metal plate is sandwiched between the foundation and the base has a drawback that the patina changed from the copper-based metal plate cannot be effectively penetrated into the base. . If patina is able to effectively penetrate the base, the toxicity of patina effectively protects the base from termite damage.

The present invention was developed for the purpose of solving this drawback. The important purpose of this device is
It is an object of the present invention to provide a foundation structure for a building which can be easily and accurately attached to the foundation and the foundation and which can effectively prevent the termite from the termite.

[0006]

The building basic structure of the present invention has the following constitution in order to achieve the above-mentioned object. That is, this invention is an improvement of the basic structure in which the copper-based metal plate 3 is sandwiched between the concrete base 1 and the base 2. In the basic structure of the present invention, a groove 4 is provided on the lower surface of the base 2 so as to extend vertically. The copper-based metal plate 3 is
The ridge 5 is fitted in the groove 4 of the base 2. The ridges 5 of the copper-based metal plate 3 are fitted into the grooves 4 of the base 2 so that the copper-based metal plate 3 is connected to the base 2. Further, the copper-based metal plate 3 is bent upward on both sides to cover the side surface of the base 2.

[0007]

In the basic structure of the building of the present invention, the ridges 5 of the copper-based metal plate 3 can be fitted into the grooves 4 of the base 2 to connect the copper-based metal plate 3 to the base 2. Therefore, the basic structure of the building of the present invention can be constructed as follows. The ridge 5 is fitted into the groove 4 and the copper-based metal plate 3 is temporarily fixed to the base 2. At this time, the foundation 1 is preliminarily attached to the base 2.
Through holes for inserting the anchor bolts 6 are provided. It is not necessary to form a through hole at the position of the anchor bolt 6 in the copper-based metal plate 3. The anchor bolt 6 of the foundation 1 is inserted into the through hole of the base 2. Since the copper-based metal plate 3 is temporarily fixed to the lower surface of the base 2, by pressing the base 2 against the anchor bolt 6, the anchor bolt 6 can be pressed by the weight and pressing force of the base 2.
The tip of the part breaks a part of the copper-based metal plate 3. The position where the anchor bolt 6 breaks the copper-based metal plate 3 is located in the through hole of the base 2. In this state, the copper-based metal plate 3 sandwiched between the base 2 and the foundation 1 does not need to be provided with a through hole in accordance with the position of the anchor bolt 6, and the base 2 is pressed against the anchor bolt 6 to make copper. The metal plate 3 can be clamped at a correct position. In this state, the copper-based metal plate 3 sandwiched between the base 2 and the foundation 1 effectively penetrates the base 2 by the patina 5 of the ridge 5 that enters the groove 4 of the base 2. In particular, the inside of the groove 4 of the base 2 is likely to be in a wet state due to the moisture absorbed by the wooden base 2, and the copper-based metal plate 3 is likely to be patina. Groove 4
The patina generated inside penetrates effectively into the inside of the wooden base 2 from the surface of the groove 4. The toxic patina that has penetrated into the base 2 effectively prevents termites from damaging the base 2.
Further, the copper-based metal plate 3 bent upward along the lower edge of the base 2 also covers the surface of the base 2, and the patina generated on the surface facing the base 2 penetrates into the base 2 to cause the base 2 to be termite. Protect from the harm of.

[Effect of the Invention] The basic structure of the building of the present invention can be attached to the foundation by temporarily fixing the copper-based metal plate to the base. In particular, a part of the copper-based metal plate can be broken by the anchor bolt by pressing the base against the anchor bolt without forming a through hole of the anchor bolt in the copper-based metal plate.
Therefore, it is not necessary to form a through hole in the copper-based metal plate in exact alignment with the position of the anchor bolt, and the base is pressed against the foundation, and the copper-based metal plate is sandwiched between the base and the foundation and fixed in position. Can be attached to. Therefore, the basic structure of the building of the present invention has a feature that the copper-based metal plate can be attached in an extremely simple and accurate position.

Further, in the basic structure of the building of the present invention, a groove is provided on the lower surface of the base, and a ridge of a copper-based metal plate is fitted into this groove. In this way, the foundation structure, which is sandwiched between the base and the foundation, and the convex strip of the copper-based metal plate is inserted into the groove, effectively penetrates the patina, which is a chemical change of the copper-based metal plate, into the base, It has the feature that it can be effectively prevented from feeding damage by termites. Especially,
Since the groove provided on the lower surface of the base is closed by the upper surface of the foundation, it tends to be in a wet state, and the copper-based metal plate tends to be patina. Furthermore, the patina generated here easily penetrates into the base from the surface of the groove. The base of patina penetrated inside is effectively prevented from termite feeding damage due to patina toxicity. In this way, the basic structure that chemically changes the copper-based metal plate into a toxic patina and penetrates it into the base to protect the base from termites has a long-term base compared to methods such as spraying chemicals.
