SHAKING PREVENTION STRUCTURE, SHAKING PREVENTION METHOD, AND CONSTRUCTION METHOD FOR TOWERING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To restrain the shaking of an upper structure from being caused by the action of an earthquake or a wind, without requiring much labor for construction or providing large-scale reinforcement, in a lift up method. SOLUTION: A shaking prevention member 80 is equipped with a jack 82 which is contracted while resisting a compressive load, and a slidable sliding bearing plate 83 which is attached to a leading end of the jack 82. The plurality of shaking prevention members 80 are horizontally installed at spacings in a plurality of three or more vertical tiers along the inner periphery of a steel tower body 20 in such a manner that the sliding bearing plate 83 can face an antenna steel tower 30. The jack 82 is constantly extended until the sliding bearing plate 83 comes into contact with the steel tower body 30. COPYRIGHT: (C)2010,JPO&INPIT
