FOOTING CONSTRUCTION OF VIBRATION ISOLATION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide footing construction of a vibration isolation structure capable of reducing a construction cost and shortening a construction period of time. ;SOLUTION: Footing beams 5 are provided to the bottom of an upper structure 4, at the same time, a footing bearing the upper structure through a laminated rubber 3 is used only for independent piles or independent direct footings, and usually, the footing beams provided so as to tie between the piles or the direct footings, are eliminated. When an independent pile 6 is used as the footing, a pile head section 6a thereof is used as a pin bearing to the ground, and allowable construction can be obtained without constraining the rotation of the pile head section to the ground.;COPYRIGHT: (C)1997,JPO
