BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing material having an anti-termite function, which is disposed on the inner wall of a cloth foundation under the floor of a building.

[0002]

2. Description of the Related Art Termites often nest in the soil under the floor of a wooden structure, and the termites may erode wood-based materials such as the foundations and pillars of the fence. Since termites prefer moist soil and wood, the underfloor, which is barely exposed to sunlight, is the most preferred environment for termites, and there is much damage to it.

For this reason, wooden structures have been traditionally used for termite control, and measures for improving drainage and ventilation have been made for a long time, but in recent years, usually termite control has been performed by spraying termite control agents. Has been done. As an anti-termite agent, creosote oil obtained by carbonizing carbon was used in the past. It is said that carboxylic acid and other aromatic compounds contained in creosote oil have an anti-termite effect, and it was applied on the surface of wood for anti-termite treatment, but since it is liquid, it is the active ingredient. Had the drawback that the ant-preventing effect did not last for a long time.

For this reason, concrete is sometimes poured into the soil so that the termites do not climb up from the nesting site in the soil to the surface of the soil of the building. The cast concrete will prevent the transfer of termites and the damage caused by termites will be suppressed to some extent.

[0005]

Even if concrete is poured into the soil, termites secrete formic acid from the mouth to dissolve the concrete, and the concrete shrinks when it dries. A gap is formed at the boundary with the inner wall of the termite, and the termites can rise through the gap. Therefore, even if concrete is cast on the floor to form a concrete floor, there is a problem in that it is not possible to obtain the expected termite-proof effect.

The present invention has been made in order to solve the above-mentioned conventional problems, and provides a sealing material having an anti-termite function capable of realizing a more effective anti-termite and a method of constructing the same. It is intended to be provided.

[0007]

A sealing material having an anti-termite function according to claim 1 of the present invention has a tubular sheet body formed of a synthetic resin sheet in which an anti-termite agent is kneaded. An elastic body is fitted and inserted in the hollow portion of the sheet body.

According to a second aspect of the present invention, there is provided a sealing material having an anti-termite function according to the first aspect of the present invention, wherein the tubular sheet body has a flat band portion on one surface, It is characterized in that it is composed of a bridge portion bridged in a mountain shape between both side portions in the width direction of the strip portion.

According to a third aspect of the present invention, in the method for applying a sealing material having an anti-termite function, the inner surface of the cloth foundation surrounding the soil below the floor has its lower surface wrapped around the inner wall of the cloth foundation. It is characterized in that a sealing material having an anti-termite function is arranged, and concrete is placed in a space surrounded by the sealing material.

[0010]

According to the sealing material having an anti-termite function according to the first aspect of the invention, the sealing material is such that the elastic body of the expandable synthetic resin is covered with the cylindrical sheet body made of synthetic resin. It is placed in a compressed state in the gap of a structure where harmful insects such as termites come and go, and the restoring force of the elastic body completely closes the gap along the form of the gap to effectively prevent the coming and going of termites. It can be used for. Then, when the sealing material is arranged in the gap of the structure or the like, the tubular sheet body makes the sliding better, and the sealing material can be easily inserted into the gap, and the tubular sheet body has a soft foaming property. It is possible to effectively prevent damage to the elastic body made of synthetic resin. In addition, since the tubular sheet body is kneaded with an ant-repellent agent, harmful insects such as termites repel this ant-anticide,
Further, it becomes possible to effectively prevent the movement of termites and the like.

According to the second aspect of the present invention, in the sealing material having a dovetail-proof function, the tubular sheet body is bridged in a mountain shape between the belt-shaped portion having one flat surface and the widthwise both side portions of the belt-shaped portion. Since it is composed of a bridge portion, it is possible to dispose the flat strip portion in a state of being in close contact with, for example, the inner side wall of the cloth foundation between the soil, such as a termite with which the inner side wall of the cloth foundation is hung. Traffic can be effectively blocked.

According to the sealing material having an anti-termite function according to the third aspect, the anti-termite function according to the first or second aspect is such that the lower surface of the cloth foundation is surrounded by the inner wall of the cloth foundation surrounding the soil below the floor. A sealing material having a sealant is arranged, and concrete in a fluid state is placed in a space surrounded by the sealing material while pressing the sealing material, so that when the concrete dries, it is placed with the inner wall of the cloth foundation. The sealing material is sandwiched between the concrete floor and the concrete floor, and the sealing material is sandwiched in the gap between the concrete floor and the inner wall of the cloth foundation formed as a result of the solidification of the concrete.

Since the sealing material sandwiched by the pressure expands due to the restoring force of the expandable synthetic resin forming the elastic body inside, the surface of the sealing material is always on the inner wall of the cloth foundation and the concrete floor. Then, the traffic of the ant and the like through the gap is completely blocked.
