An example of a turbine building will be explained with reference to FIG. 4.The entire building 1 is comparable in size to a high-rise building, and the inside of two rows of main columns 2.2 separated by a large span is an internal column 3.2. 3 and 4 are made of reinforced concrete, and the roof part 5 is made of steel frame. There is an attached layer 6.6 on the outside of the main pillar 2.2, and the base 7 of the entire basement part is also made of reinforced concrete.

が挙げられ、いずれも大型の重量機器である。Currently, many of the power plants being constructed to meet the electricity demand are thermal or nuclear power plants, and a turbine T is installed in the center of the turbine building 1.
1 generator G is arranged, supported by a frame called a pedestal, and installed on the top surface of the frame. The main equipment attached to the turbine T includes a condenser C1 and a low-pressure feed water heater H, all of which are large and heavy equipment.

た前記天井走行クレーン９を使って据付けを行う。Next, to describe the installation of heavy equipment in the bin building 1, before assembling the turbine T1 generator G,
The condenser C and low-pressure feed water heater H will be installed, but since both equipment require a very long process due to equipment piping work, they will be brought in early without waiting for the overhead traveling crane 9 to start operating.
Must be installed. Therefore, a board opening E is provided on the side wall of the building 1, and a temporary pedestal Sl is provided for the roller lead-in path of the condenser C, and a roller lead-in path for various equipment such as the low-pressure feed water heater H located on the upper floor. An elevated temporary pedestal S2 for the road will be erected. On the other hand, heavy equipment is transported on a large trailer, unloaded using a large temporary lifting machine K, received on the pedestal, taken in from the board opening of the side wall of the building 1, and then pulled horizontally. Perform installation. Subsequently, the turbine T1 generator G was carried in and installed, but as before, both heavy equipment were transported by a large trailer and brought in through the board opening in the side wall of the building, and the overhead traveling crane 9, which was now ready for operation, was moved. Use it for installation.

。The scale of the turbine building 1 is, in the example of a 1 million KW class power plant, the span of the main column 2 is 40 m, the height is 40 m above ground, and the rows are 10.
0 to 120 m, and the height of the operation floor 8 is about 18 m.

終了しないとコンクリートが打設できない場合が多い。Problems that the invention aims to solve Not only in turbine buildings but also in buildings with a large number of equipment, there is always an overlap in the construction period between the construction process and the equipment process, and if work is received and handed over by process, the construction period will be delayed. do. Furthermore, in construction work, a curing period is required after pouring to ensure sound concrete before equipment installation, and conversely, concrete cannot often be poured until equipment installation is completed.

る広い面積にわたって次工程の妨害となる。In particular, when there is a lot of large and heavy equipment, such as in a turbine building, a temporary lifting machine K is required and a large crawler crane is used. This is uneconomical, and since operation from outside the building does not take advantage of the great mobility, a temporary load receiving rack S2 and a retractable rack S1 from there are required. Although the labor and construction time required for its installation and removal are not as important as its effectiveness, it also interferes with the next process over a wide area that corresponds to the lead-in path, along with the accompanying repair of the board frontage.

受は渡しが大きな課題であった。On the other hand, the overhead traveling crane 9 was installed after the reinforced concrete construction of the main pillar 2, and even after it started operating, it could hardly be used for horizontally moving equipment to be brought in from the outside, and this horizontal movement is the reason why the equipment installation work is labor-intensive. This became a problem in terms of both the construction period and construction period, and in addition, the delivery of the construction period for this type of work and construction work was a major issue.

る。Means for Solving the Problems The present invention is designed to fundamentally reconsider the organization of each process of conventional construction methods in buildings such as turbine buildings where the processes of construction work and installation of heavy equipment are complicated. It was developed with the aim of providing a rational construction method. This construction method enables the overhead traveling crane installed in this type of building to operate relatively early in the construction work, and by operating the traveling crane, congestion between construction work and heavy equipment installation work is reduced. The main idea is to avoid this and shorten the overall construction period. In the present invention, construction of the steel frame structure up to the operation floor, which is the main floor of the building, is carried out in advance, and a temporary runway is provided on the upper surface for the overhead traveling crane for the permanent installation. The most distinctive feature is the process of attaching temporary legs to the crane to form a gate-shaped crane, which can be operated on the runway. For this purpose, the temporary runway is extended outdoors in the direction of travel, and that part is supported by a temporary pedestal to serve as a cargo receiving area. As a result, when installing equipment using a portal crane, it is possible to lift and move freely on the entire operation floor, without affecting parallel construction work, especially concrete work, and after construction is completed, the traveling crane can be used as the original crane.・It is easy to reposition on rails and remove temporary gate-shaped legs.

This portal crane utilizes the main body 91 of the permanent overhead traveling crane 9, and a pair of temporary legs 101 each having two column bodies and a traveling body are placed at positions corresponding to the spans of the internal columns 31 and 31. .101
Assemble and configure. The height of the temporary legs 101 is set to be greater than or equal to the height at which the main body 91 is supported on the running surface of the permanent overhead traveling crane 9 when the portal crane 10 is placed on the runway 12. The portal crane 10 can be lifted from the side of the building 1 or the gantry 20 using a lifting machine, and can be easily installed on the runway 12. The portal crane 10 is temporarily installed with the main body 91 on the runway 12! ! 1l101 may be directly assembled.

Turbine T after a curing period
1 generator G is carried in using a portal crane 10 and installed. There is no need to explain the transport and installation of small equipment, but at this stage the upper part of Building 1 is free space, and it is possible to transport and install the equipment directly using a general lifting machine rather than using a gantry crane. A certain point is emphasized.

のブロック化ができ、現場の工期が短縮できる。Effects of the Invention According to the construction method of the present invention, the existing overhead traveling crane can be configured into a gantry crane at an early stage of construction work, and can be operated for lifting and transporting, making it possible to perform horizontal movement operations at the time of delivery. This makes it possible to directly install heavy equipment simply by lowering it from above, and there is no need to disassemble and transport the equipment, allowing it to be made into large blocks at the prefabrication stage, reducing construction time on site. can be shortened.
この間に搬入据付の工程と建築工事の工程が錯綜せず、
相互に待ち期間が回避できるから、建設工程の全体を短

Since waiting periods can be avoided, it contributes to shortening the entire construction process, and there is no need to deploy large lifting machines for a long period of time, greatly improving economic efficiency in that respect.

大きな負担となることはない。The steel frame structure that will be constructed in advance will be used as the frame material that makes up the building, and the crane body of the portal crane is also the body of the permanent overhead traveling crane, so temporary legs will be used as temporary materials. These steel materials do not require special materials, can be reused, and are not a big burden compared to the utility of their use.
