The upper part of the turbine body 1 is supported by the top part 3b of the turbine pedestal 3. A plurality of equipment chambers 4 for accommodating various types of equipment (not shown) are arranged around the outer periphery of the turbine pedestal 3, and an adjacent wall 4a of the equipment room 4 adjacent to the outer periphery of the turbine pedestal 3 and an outer peripheral surface of the turbine pedestal 3 are provided with A required gap 5 is set for vibration prevention. Further, a turbine building roof 6 is horizontally suspended above the turbine main body 1.

Next, a conventional turbine building construction method will be explained based on FIG. 3.

Formwork and concrete pouring are carried out in several parts, and the column parts 3a of the turbine pedestal 3 are erected one after another.

After the top 3b of the column 3a is completed, the scaffolding around the outer periphery of the turbine pedestal 3 is dismantled.

After such turbine pedestal construction work is completed,
The equipment room 4, which will be the installation area for turbine system equipment around the outer periphery of the turbine pedestal 3, will be built from the bottom up, with reinforcing bars, formwork, and concrete being poured in that order. After the construction work of this equipment room 4 is completed, the steel frame assembly and reinforced concrete work for the turbine building roof 6 are performed to complete the turbine building. After the turbine building is completed, the turbine main body 1 and the generator main body (not shown) are installed.

However, in such a conventional turbine building construction method, there is a gap between the turbine pedestal 3 and the adjacent wall 4a of the equipment room 4 adjacent to the outer periphery of the turbine pedestal 3. For example, about 5 In! to prevent the photographing from affecting other equipment and to prevent the turbine body 1 from being affected by the vibrations of other equipment. A gap 5 of approximately R is provided. For this purpose, after completion of the turbine pedestal 3, construction work for the equipment room 4 was started so as to have a predetermined gap 5. As a result, the construction period for the turbine building becomes longer, and the installation of equipment in the turbine building, piping work, and installation of the turbine itself are also delayed, resulting in a problem that the power plant construction period becomes longer.

(Objective of the Invention) An object of the present invention is to provide a construction method for a turbine building that can significantly shorten the construction period of a power plant and improve the efficiency of construction work by shortening the construction period of the turbine building. be.

(Summary of the Invention) In order to achieve the above-mentioned object, the present invention integrates a turbine pedestal and an adjacent wall of an orthopedic chamber adjacent to the outer periphery of the turbine pedestal, and performs construction work of the integrated turbine pedestal. The construction work of the equipment room is carried out in parallel, and the top part of the turbine pedestal is constructed by interposing an elastic member between the upper part and the lower part of the turbine pedestal construction work.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings.

That is, the lower outer periphery of the turbine body 1 is surrounded by the pillar portion 10a of the turbine pedestal 10, and the upper part of the turbine body 1 is supported by the top portion 10b of the turbine pedestal 10. The column portion 10a of the turbine pedestal 10 is connected to an adjacent wall 11a of the equipment room 11 adjacent to the outer periphery of the column portion 10a.
As in the conventional example shown in FIG.
No gap 5 is provided between a and the adjacent wall 11a. On the other hand, the top part 10b of the turbine pedestal 10 that supports the upper part of the turbine body 1 is vertically defined by an upper part 12 and a lower part 13, and a spring unit 14 is provided in a gap 10c in the defined part, as shown in FIG. is mediated. Adhesive plates 15 are provided on both upper and lower surfaces of the spring unit 14, respectively.

Next, an embodiment of a construction method for a turbine building constructed in this manner will be described.

First, as shown in Figure 1, the mat 2, which is the foundation of the building,
Reinforcement, formwork, and concrete placement will be carried out. This process is the same as before. After the mat 2 is completed, the construction work of the column part 10a of the turbine pedestal 10 and the construction work of the equipment room 11 arranged around the outer periphery of this column part 10a are carried out in parallel. That is, the pillar portion 10a of the turbine pedestal 10
is formed on the wall of the chamber 11 adjacent to the outer periphery of the column 10a, and the column 10a is erected by sequentially assembling scaffolding, reinforcing bars, and placing concrete. Then, when the construction level of this column 10a reaches the lower part 13 of the turbine pedestal top 10b, the upper part 12 of the turbine pedestal top 10b, which becomes the foundation of the turbine body 1, is constructed. That is, as shown in the partially enlarged view of FIG. 2, after concrete is placed in the lower part 13 of the turbine pedestal top 10b, the level of the concrete surface is measured.

Next, an elastic adhesive board 15 is placed on the concrete surface, and the spring unit 14 is set on this adhesive board 15. Next, the support assembly for the upper part 12 of the turbine pedestal top 10b and the formwork installation are carried out. , assembling reinforcing bars, installing anchor bolts for the turbine body 1, etc. At this time, the elastic adhesive plate 15 on the spring unit 14 and the shim plate 16 for adjusting the lever are set.
