DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a method for simultaneously constructing a steel frame building and piping, and more particularly, to a thermal power generation facility, for example.

- This invention relates to a method for simultaneously constructing a steel frame building and piping, which is suitable for use in installing an axial type combined cycle power plant.

[Background of the invention]

In the field of thermal power generation, which is the mainstay of the electric power business, the so-called combined cycle power generation equipment, which combines a gas turbine and a steam turbine, has recently been attracting attention as a new energy-saving technology. It has advantages such as high thermal efficiency and short startup and shutdown times.

Figure 13 is an explanatory diagram of the operating system of a combined cycle power generation facility, in which 1 is a gas turbine, 2 is a steam turbine, 3 is a generator, 4 is an exhaust gas passage of the gas turbine, and 5 is an exhaust heat recovery boiler. (HR3G), the exhaust gas from the gas turbine 1 is led to the exhaust heat recovery boiler 5 through the passage 4, steam is generated in the boiler 5 section, and the steam turbine 2 is rotated by this steam. But.

Combined cycle power generation! Among Qm, -axis type combined cycle i'! The equipment has advantages such as short startup and shutdown times and easy periodic inspection, and its configuration is as shown in FIG. 14. That is, the configuration of the -shaft type combined cycle power generation equipment is as shown in FIG.
5 Generator 3. The steam turbine 2 is arranged in a straight line with the exhaust heat recovery boiler 5 in what is called a ■-type arrangement, and a large number of units called the ■-type device are arranged to form one series, and the above-mentioned The line length of the series is long, and common piping is installed for each of the above two units.

Therefore, when installing the power generation equipment described above in the steel frame building 6, conventionally the main columns are arranged in the longitudinal direction of the building 6 and beams are hung between the main columns. The erection process and piping installation for Building 6 are completely different processes, and the steel frame building ff16-1
After finishing the northing, the main engine is brought into the building 6, and then the piping is laid. In addition, when installing piping after completing the erection of the steel frame building 6, since the inner and outer wall panels have already been attached to the steel frame building 6, the position where the piping is taken into the steel frame building 6 is the 14th
There is no choice but to use the main engine entrance shown by reference numeral 7 in the figure. 1st
FIG. 5 is a perspective view showing a conventional example of piping intake into a steel frame building 6, and is a conventional example.

In order to take the piping 8 into the steel frame building 6, as shown in FIG. Thereafter, the piping 8 is taken into the steel frame building m6 using chain blocks, wires, etc., and horizontally pulled to a predetermined position.

However, according to the conventional method described above, the steel frame building 6
Since the construction process and the installation process of the piping 8 are so-called series processes, the period from the start of construction to the start of plant operation is unavoidably long. The relevant piping 8
Due to the limited length of the pipe 8, not only the number of times the pipe 8 is taken in increases, but also the number of welding points of the pipe 8 taken into the steel frame building 6 increases. Furthermore, the piping 8 must be laid after the steel frame building 6 has been erected.

Already the interior and exterior wall panels (in Fig. 15, the exterior wall panels are marked 1)
Piping 8 is installed inside the steel frame building 6 where the
This means that the work of bringing in a large number of pipes 8 into the steel frame building 6, which has a complex structure surrounded by internal and external wall panels, becomes extremely complicated.Moreover, while the pipes 8 are being taken in, there is a crane truck on the main engine loading lower. 9 is stopped, the main engine cannot be carried in from the loading lower.

In addition, Japanese Patent Application Laid-open No. 57-684 titled "Method of constructing buildings"
Publication No. 36 states that ``fittings (fittings for attaching building equipment such as piping) should be installed at the same time as the concrete for the building skeleton is poured. What is installed at the same time as 1~ is only the metal fittings that support the building equipment, not the building equipment such as piping, and these building equipment are made by drying and solidifying the concrete that is the building frame It is installed later, and in this point it is essentially different from the present invention, which will be described later.
