摘要

Recently the recycling law regarding construction was in force to preserve the earth environment. It is requested to pick up the non-damaged wooden materials at the site of dismantled wooden house to reuse and recycle. As the machine dismantling system is carried out for the wooden houses, we can not obtain the non-damaged wooden member. The hand dismantling system is requested to get the non-damaged wooden member. The investigation of the waste and dismantling system for the five houses was conducted. The trouble of dismantling changes with the method of dismantling process and the situation of the house. The trouble decreases according to the floor space increasing. The rate of the wood decay was dependent on the completion year.
