EARTHQUAKE RESISTANT FIXING HARDWARE

PROBLEM TO BE SOLVED: To provide an earthquake resistant fixing hardware whose assembling and adjustment of length can be facilitated and which can secure a sufficient large rigidity and improves the earthquake resistant performance. SOLUTION: In an earthquake resistant fixing hardware for equipment S arranged on a double floor structure composed of a building floor C and a free access floor B, one of them is fixed to the building floor C and the other one is fixed to the equipment through the free access floor B. Further, the hardware is provided with a pair of turnbuckle bolts 4A, 4B in which mutually reverse screw parts are formed at the ends opposite to respective fitting fixed sides, and mutually reverse screw holes screwing up the screw parts of these turnbuckle bolts 4A, 4B, and a turnbuckle drum 3 extensibly connecting the mutual turnbuckles 4A, 4B.
