PROBLEM TO BE SOLVED: To provide the auxiliary instrument of an attic connection part on a wooden framework structural building making a box type by forming a corner and a side by adjacent faces and forming a fixing hole without using the connection of a strip-like plate material aiding the prevention of column pulling, column slip and column torsion produced by aging and large and small vibration of the attic connection part on the wooden framework structural building. SOLUTION: The prevention of pulling, column slip and column torsion is aided by receiving and supporting the force of an attic connection part applied on column B, C pulling, column slip and column torsion produced by aging and large and small vibration of the attic connection part on a wooden framework structural building by faces and sides adjacent to the column B, C. Adjacent faces form a corner and a side without using the connection of a strip-like plate material, and a box type forming a fixing hole 2 on each face is made. |
