PROBLEM TO BE SOLVED: To provide a structural reinforcing method to reinforce a flaw such as a split and a crack generated in the direction orthogonal to the material axis or the direction near to its direction, caused in a framework member, particularly, in a bending member such as a beam material and a girder material, in a traditional wooden building such as Buddhist temple and Shinto shrine buildings and a frame work member of a conventional method of a relatively large scale. SOLUTION: A female screw bolt 3 is embedded in the substantially right-angled direction to a material surface in its both right-left positions around a reinforcement requiring place 2 of a wooden building structural material 1. A joining tool 4 manufactured by a shape memory alloy of contracting by heating, is installed by a bolt 5 between the right-left female screw bolts 3 and 3. Afterwards, tensional force is generated by heating the joining tool 4 up to the contraction temperature of the shape memory alloy. COPYRIGHT: (C)2008,JPO&INPIT
