  The present invention relates to a basic heat insulating structure of a building in which a basic heat insulating material is closely attached to an inner surface of a rising portion of a fabric foundation constructed on the outer periphery of the building, and more specifically, termites enter the inside of the basic heat insulating material. The present invention relates to a basic heat insulating structure of a building for checking whether or not to perform ant protection reprocessing.

As shown in FIG. 7 and FIG. 8, when so-called internal heat insulation of the building 51 in a cold district or the like, the basic heat insulating material 54 is provided on the inner side surface 3 a of the rising portion 3 of the cloth foundation 2 constructed on the outer peripheral portion of the building 51. It is common to make it closely_contact | adhere (for example, refer patent document 1).
Japanese Patent Laying-Open No. 2005-83137 (FIGS. 5, 6, 8, etc.)

  As shown in FIG. 7, when the foundation heat insulating material 54 is provided so as to contact the floor base board 7, the soil concrete 6 on the floor base board 7 is inward from the base heat insulating material 54 in close contact with the inner side surface 3 a of the rising portion 3. It is constructed to be handed over to. In this case, in general, the application of an antifungal agent to the inner side surface 3 a of the rising portion 3, the application or mixing of the antifungal agent to the basic heat insulating material 54, and the antifungal agent to the outer peripheral portion or the entire surface of the floor base board 7. Ant protection is performed by spraying the agent.

  On the other hand, as shown in FIG. 8, when the foundation heat insulating material 54 is provided so as not to contact the floor base board 7, the soil concrete 6 is constructed so as to be handed inward from the rising portion 3. In this case, the foundation heat insulating material 34 is provided so as to be adjacent to the upper part of the soil concrete 6, and the soil heat insulating material 35 may be further laid on the soil concrete 6 so as to be adjacent to the inside of the foundation heat insulating material 34. Many. In general, the ant-proofing treatment is performed by spraying the ant-proofing agent on the outer peripheral portion or the entire surface of the floor base board 7.

  Since the effective period of the termite-preventing agent used for the above-mentioned anti-antacting treatment is about 5 to 10 years, termites have entered the basic heat insulating materials 54 and 34 before the effective period elapses. It is desirable to check whether or not, and if necessary, retreat the ants.

  However, in the conventional example of FIG. 7 and the conventional example of FIG. 8, in order to check whether termites have penetrated the inside of the basic heat insulating materials 54, 34, at least a part of the basic heat insulating materials 54, 34 is used.
