RESIDUAL DEFORMATION SUPPRESSION STRUCTURE OF FRAMEWORK JOINING PART

摘要

PROBLEM TO BE SOLVED: To suppress the residual deformation of a joining part in a framework of a building by a small number of constituents and an easy construction method.SOLUTION: A residual deformation suppression structure 10 comprises resilience force impartment means 15 which imparts a restoration force in a direction in which a horizontal material 12 and a column 11 approximate each other when an external force acts in a direction in which the horizontal material is separated from the column, and accommodation means 16 which accommodates the restoration force impartment means 15 into the column 11 and the horizontal material 12. The restoration force impartment means 15 comprises a joining member 21 which joins the column 11 and the horizontal material 12 to each other, and a coil spring 23 which is attached to the joining member 21, and restores a joining part C to an original joining state when there occurs deformation in the separation direction. The accommodation means 16 is formed so that the joining member 21 can be bridged between the column 11 and the horizontal material 12, and arranged so as to be accessible to the joining member 21 from the outside of the column 11 and the horizontal material 12 in a state that the restoration force impartment means 15 is accommodated.
