BOILER SUPPORT STRUCTURE

摘要

A boiler support structure is provided that is capable of significantly reducing an effect of a seismic force and also capable of vibrating integrally during an earthquake. The boiler support structure is provided with a main boiler body (3), a support steel frame (11) that supports the main boiler body (3) in a suspended state and that includes a plurality of pillars (11a) that each stand on a foundation (1) with a pillar legs (11b) placed therebetween and a plurality of beams (11c) that connect the adjacent pillars (11a), and seismic isolation devices (5) that support the plurality of respective pillars (11a). In the boiler support structure (10), seismic isolation characteristics of each of the seismic isolation devices (5) are set in accordance with horizontal reaction forces occurring in the plurality of pillar legs (11b).
