PROBLEM TO BE SOLVED: To provide a demolition method for a boiler and a boiler building, which enables boiler dismantling operations to be performed on the ground or in a low place near the ground, without being performed in a high place, which prevents the boiler from falling due to the weight of the ceiling beam, the boiler, etc., suspended by a jack, which facilitates ceiling beam cutting work, and which dispenses with a step of cutting a connecting material for connecting the ceiling beam and the boiler together. SOLUTION: A temporary beam 3 is placed and fixed on the permanent column of the boiler building 1. The jack 5 is provided in a prescribed position on the temporary beam 3. A hanging member 7 of the jack 5 is latched to the ceiling beam 6. The ceiling beam 6 is separated from the boiler building 1 by cutting both ends of the ceiling beam 6. The ceiling beam 6 and the boiler 4 are lowered by paying out the hanging member 7 from the jack 5, and stopped for the dismantlement of the boiler 4. COPYRIGHT: (C)2010,JPO&INPIT
