PROBLEM TO BE SOLVED: To spread a seismic control construction method by solving the problems wherein although the seismic control construction method is commercialized in the form of a seismic control panel, it is expensive, requires skill to insert a heat insulating material and is laborious to install. SOLUTION: A plurality of viscoelastic bodies of different dynamic characteristics fill gaps between a two-layered steel block 1 and a two- or three-layered steel block 2 to form a spatial structure against a planar structure of a seismic control panel. The steel block 1 and the steel block 2 are coupled with movable bolts. Vibrational energy of an earthquake or the like propagates through the steel blocks and to the three or four viscoelastic body layers, wherein it is consumed and damped. Such a seismic control fitting is mounted on the most efficient place in a general wooden house of a position where a column and a beam, or a column and a sill are joined. A seismic control effect works on vibrational energy of an earthquake or the like, and after the effect, the three bolts exert an effect as a joint fitting. COPYRIGHT: (C)2003,JPO
