PROBLEM TO BE SOLVED: To inhibit corruption that is caused by feeding damage of termites and rot fungi even if the termites reach a wooden structural material and a wooden statue by humidity rise due to heavy rainfall and inundation.SOLUTION: A first structural material 14 and a second structural material 15 of a cross posture are connected by a fitting between a tenon 12 and a tenon hole 13. An anti-termite sheet 17 for making a base material 19 carry an anti-termite agent and having an adhesion layer 20 is stuck on an end face 16 of the first structural material 14. The termite has a nature to invade from an end face (butt end) of wood. However, even if the termite reaches a joint of structures 14, 15 due to humidity rise, the anti-termite agent leaching or eluded from the anti-termite sheet 17 shifts to the first structural material 14, and thereby feeding damage of the first structural material 14 can be inhibited. Preservatives can be used in addition to or in place of the anti-termite agent.SELECTED DRAWING: Figure 2 |
