のが通常である。2. Description of the Related Art A termite damage to a wooden building is very large, and a new building may be damaged in a short period of time as well as a building that has passed a certain number of years. The damage is not limited to the foundation and pillars, but can also extend to the roof.
Since the termite feeding damage will be lost soon after it is discovered, it is usual to carry out drug treatment for termite control beforehand.
【０００３】ところが、かつて汎用されていたクロルデ

剤処理を行わなければならない。However, the use of termite control agents, such as chlordane, which has been widely used for a long time and has a long-term effect, is prohibited. Therefore, it is necessary to carry out the chemical treatment at short intervals such as every year.

かなり進行してしまうことが多い。食害が進行した木質
材は、内部が巣になっており、強度が著しく低減してい
る。However, such frequent drug treatments are often complicated and expensive, and thus can be neglected. As a result, the termite feeding damage to the wooden building often progresses considerably. The wood material that has been damaged by feeding has a nest inside and the strength is remarkably reduced.
【０００５】このような段階になってから薬剤処理する

ようにどうしても取り替え不可能な個所がある。[0005] It is no longer worthwhile to treat with chemicals after such a stage (even if it is meant to prevent the spread of food damage to surrounding wood materials), and the foundations, columns, girders (beams) that have been damaged ), Purlins, rafters, flooring, joists, lintels, pallets, etc. can only be replaced with new ones, but there are places such as girders and purlins that cannot be replaced.
【０００６】特に文化財建築物においては、柱などを新

ものを損なってしまうことになるので、対策に窮する。Particularly in the case of a cultural property building, exchanging pillars with new ones will impair the value itself as a cultural property, so it is difficult to take measures.
【０００７】もし食害が進行した木質材を強化復元する

る。Means for Solving the Problems The method for strengthening a termite-feeding material according to the present invention comprises infiltrating a 2-cyanoacrylate compound from the inside or the surface of the wood material into the tissue of the wood material damaged by the termites. It is characterized in that the 2-cyanoacrylate compound is cured in the structure of the wood material by reacting with the water in the wood material.

【００１２】本発明においては、シロアリによる食害を
受けた木質材の組織内に、その木質材の内部または表面
から２−シアノアクリレート化合物を浸透させる。In the present invention, the 2-cyanoacrylate compound is permeated into the tissue of the wood material damaged by termites from the inside or the surface of the wood material.
【００１３】この場合、木質材の表面からの浸透には限

化合物を浸透させることが特に好ましい。In this case, since there is a limit to the permeation of the wood material from the surface, a hole is made in an appropriate portion of the wood material that has been damaged by feeding, and the 2-cyanoacrylate compound is injected through the hole to remove the wood material. It is particularly preferable to penetrate the 2-cyanoacrylate compound from the inside into the tissue.

しておくことが望ましい。Drilling is usually performed by a drill. The number of holes is set to an appropriate number (for example, several to ten or more) while observing the damage condition. The injected 2-cyanoacrylate compound flows down and diffuses inside while penetrating the tissue around the nest formed inside the wood material. Excess runoff flows out from the lower part of the wood material, so it is desirable to protect the lower part of the wood material with an enclosure such as tape so that it does not flow around and contaminate.

る。Examples of the 2-cyanoacrylate compound include alkyl 2-cyanoacrylate, cycloalkyl 2-cyanoacrylate and alkoxyalkyl.
A 2-cyanoacrylate compound such as 2-cyanoacrylate, alkenyl 2-cyanoacrylate, or alkynyl 2-cyanoacrylate is used. In these 2-cyanoacrylate compounds, if necessary, a polymerization inhibitor, a stabilizer, a thickener, a heat resistance imparting agent, a plasticizer, and a pH.

From the hole, 2-
Injecting a cyanoacrylate compound so that it penetrates into the tissue from the inside of the wood material), the inside of the wood material that has been damaged by feeding becomes a nest, so the injected 2-cyanoacrylate compound is While flowing into the internal structure of the wood material, it flows down and diffuses inside. Then, the 2-cyanoacrylate compound promptly reacts with the water in the wood material to be hardened (polymerized) in the tissue of the wood material to strengthen the wood material. Moreover, the termites in the wood material are exterminated by the heat of reaction during polymerization, and the hardened tissue of the wood material is no longer susceptible to termite feeding damage.

In Example 3, since odorlessly low ethoxyethyl 2-cyanoacrylate was used, almost no odor was observed during the above operation. After fever, the temperature gradually dropped and after about 3 to 7 minutes, the temperature returned to near room temperature.

As a result, a remarkable nest (lacking in the softness between the annual rings from the outer surface of the column to a point of 5 to 45 mm) However, it was confirmed that 2-cyanoacrylate penetrated into the remaining structure and was hardened and hardened, and the remaining structure was highly reinforced. Since this hardened tissue is extremely hard, it is hard to be damaged by termites.
