BOILER SUPPORT STRUCTURE
PROBLEM TO BE SOLVED: To provide a boiler support structure capable of drastically reducing an acting seismic force and capable of integrally vibrating during earthquakes.SOLUTION: A boiler support structure 10 includes: a boiler body 3; a support iron frame 11 which comprises a plurality of columns 11a erected via a column base 11b on a foundation 1 and a plurality of beams 11c for tying the adjacent columns 11a together, and which supports the boiler body 3 in the state of suspending it; and a base-isolating device 5 for supporting each of the plurality of columns 11a. In each of the base-isolating devices 5, base-isolation characteristics are set depending on horizontal reaction generated on the plurality of column bases 11b. The base-isolating device 5 is provided between the foundation 1 and the column base 11b.
【課題】作用する地震力を大幅に低減できるとともに、地震時に一体となって振動することが可能なボイラの支持構造体を提供する。【解決手段】ボイラ本体３と、基礎１に柱脚１１ｂを介して立設される複数の柱１１ａと、隣接する柱１１ａを繋ぐ複数の梁１１ｃと、備え、ボイラ本体３を吊下げて支持する支持鉄骨１１と、複数の柱１１ａの各々を支持する免震装置５と、を備える。各々の免震装置５は、複数の柱脚１１ｂに生じる水平反力に応じて、免震特性が設定されるボイラ支持構造体１０。免震装置５は、基礎１と柱脚１１ｂの間に設けられる。【選択図】図１
