<p>PROBLEM TO BE SOLVED: To solve such problems in a timber frame construction method that some metal components are used in joints, and then the components themselves are critical points of stress and force concentrates thereon, and the balance of strength with timbers is the most important examination places of the frame construction method, however, in the fire, it is even the cause of risk in which the strength of the contact points with the timbers is yielded at a remarkably fast rate in the state where structural stress is concentrated on a local part due to high thermal conductivity of the metal components.SOLUTION: Joints using metal components are eliminated from the main structure part of a timber frame construction method in which the efficiency of fire resistance is demanded. Fireproof charring coating is formed in the whole of structural materials by gapless wooden joints on the basis of an adhesion system, and thereby the joint of total cross section type stress is provided in which a localized stress is not concentrated to a part of the member.</p> |
