Description

[Detailed description of the invention]

This invention relates to an underfloor paving method for obtaining moisture-proofing and termite-proofing effects under building floors. Generally, when the humidity under the floor of a building becomes high, various problems occur. First of all, if the wood under the floor gets wet, due to the nature of the wood, it will deteriorate quickly and rot, which can even cause the foundation to collapse. When the humidity under the floor and floorboards increases, there is a high possibility that the fungus, which is a basidiomycete fungus belonging to the family Shiwatake family and is widely distributed throughout the world, will grow all over the floor. This fungus is also called a house fungus because it likes moisture and spreads and rots the wooden parts of houses, especially floorboards, and along with the termites mentioned below, it is something that should be avoided in buildings at all costs. Additionally, if the wood under the floor or the subfloor is damp, there is a risk of termite damage.
Termites habitually nest at a depth of about 30 cm below the soil surface, build ant trails in the soil, prefer poor ventilation, warm, humid, and dark places, and damage wood in damp conditions. In houses, the best places for termites are under floors, especially bathrooms, kitchens, washrooms, toilets, places with rain leaks, and under the eaves where they are exposed to rain, and the wooden parts such as foundations and pillars in these places are ideal for termites. Becomes food. The damage caused by termites is so severe that if a house is left unnoticed for some time, the foundation of the house is destroyed and it is often impossible to repair the house. Conventionally, as a moisture-proofing measure under the floor of a building, a polyethylene sheet was laid from the ground level under the floor to the bundle stones and foundation, and then sand was spread evenly to a thickness of about 5 cm on top of the sheet, or concrete was poured on top of the subfloor. method is being carried out. Although the above method using polyethylene sheets has a moisture-proofing effect in the space under the floor, water droplets aggregate in the overlapping areas of the sheets, on the stacking stones, and near the wooden foundations above the foundations, which can lead to the formation of the above-mentioned Namida mushrooms. On the other hand, although concrete with a dirt floor has a moisture-proofing effect compared to soil, condensation is likely to occur on the concrete surface. On the other hand, in order to prevent termites under the floor, the general method is to infiltrate the inside and outside of the foundation, around the pile stones, or the entire surface of the subfloor, or perform soil treatment such as mixing it with the soil. Wood treatments such as soaking, painting, spraying, and perforation injection with insecticides are also used. However, with this method, it is difficult to obtain a moisture-proofing effect under the floor. This invention was made in view of the above circumstances,
The purpose of this is to provide a subfloor paving method that improves the moisture-proofing effect of the subfloor and strengthens the control against termite damage. It is designed to spray asphalt emulsion. This invention will be explained in detail below. In this invention, after leveling the subfloor of a building, a 2 to 5 cm thick bituminous mixture at room temperature or heating or a bituminous mixture for termite prevention is directly paved on the entire surface of the subfloor, and on top of that, asphalt emulsion or 0.1 to 5% by weight is applied. Asphalt emulsion for termite prevention added with termite control agent
It is characterized by being sprayed at a rate of 0.3 to 2/m ² . Next, examples will be shown to specifically explain the present invention. Example: The following room-temperature termite-proofing mixture was paved to a thickness of 3 cm under the floor of a gymnasium, and 2% chlordane was added to the asphalt emulsion PK-3 over the entire paved surface of the above-mentioned termite-proofing room-temperature mixture from around the pile stones and foundations. The added/prepared anti-termite emulsion is 1/
When sprayed with ^m2 , there was no termite damage for a long period of time (5 years). In addition, the floor surface was well dry and no growth of Namidata mushrooms was observed. "Room-temperature mixture for termite prevention" Mixed aggregate shown in the table below is heated to 110℃, and cutback asphalt heated to 70℃ is added to this mixed aggregate.
Add 5.7% MC800 and mix, then patent No. 598311
A room-temperature mixture for termite prevention that can be stored for a long time and manufactured by spraying 0.6% of the light component oil used in No. 1 with 2% chlordane mixed into the above mixture.

[Table] As can be seen from the above explanation, the underfloor paving method according to the present invention enhances the moisture-proofing and termite-proofing effects of the underfloor of buildings, prevents damage to buildings caused by moisture, improves livability, and is effective in controlling termite damage. It has the following.
