Are formed in a box shape by appropriately providing a plurality of steel plate ribs 77 and welding them to the respective plates.

However, the conventional common gantry 20 shown in FIGS. 5 and 6 has the following problems. That is, it is formed into a box-like body by bending or welding as it is with a large number of steel plates, and because the number of steel plates increases to maintain rigidity, the number of welding spots increases and welding is difficult due to the box-like body. There are some parts. For this reason, the number of steps of the welding work increases, and the welding workability is low.

In addition, since the box-like body is used, a space for piping and wiring for equipment is secured, so that the width of the common frame 20 is wide and the compactness is lacking. Furthermore, since it is a box-shaped body, heat is easily trapped inside, so that heat dissipation is low, which may cause overheating of devices.

An object of the present invention is to reduce the number of steel materials, to reduce the number of welding points and to improve welding workability, to have high rigidity, to make piping and wiring compact, and to further reduce heat dissipation. An object of the present invention is to provide a common mounting base for equipment which is favorable and can avoid overheating of equipment.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and the first means, which is the gist thereof, is:
In a common mounting base for equipment in which a plurality of equipment such as a turbine and a generator are fixed to one mounting base, the common mounting base is formed by welding a plurality of H-shaped steels and steel plates, and the common mounting base is formed by welding. A space for mounting the above equipment and a cavity for inserting piping, wiring, and the like therein are provided to penetrate vertically from the floor plate to the bottom plate.

The second means is the first means,
The common gantry includes a side structural member including a vertical plate that vertically couples both the side floor plate and the side bottom plate, and a vertical structural plate that vertically couples both the front floor plate and the front bottom plate. The H-shaped steel is used as a structural member and a structural member including a rear floor plate and a vertical plate that vertically couples both the rear floor plate and the rear bottom plate.

According to the above means, the common frame comprises at least the side structural member, the front structural member and the rear structural member constituting the outer shell made of a highly rigid H-shaped steel, which is reinforced with ribs made of a steel plate. With this structure, the gantry has high rigidity with a small number of structural members as compared with the conventional steel gantry made of a steel plate welded body, and has a reduced gantry weight.

Therefore, it is possible to reduce the number of welding points and to form a large number of vertical cavities while maintaining rigidity, so that there are no difficult-to-weld parts and the number of welding operations is significantly reduced as compared with the conventional one. Is done.

Further, since a large number of vertical cavities are formed between the structural members made of H-section steel, piping and wiring can be performed through these cavities. This makes it possible to easily perform piping and wiring work without having to route piping and wiring around the outside of the common stand unlike the conventional one, and it is compact because there is no exposure of piping and wiring to the outside. Aesthetics also improve.

Further, since a large number of cavities are formed in the common frame and the space is open to the outside without a closed space, heat radiation is improved, and heat is trapped inside the frame to allow equipment and wiring to be installed. It does not cause overheating.
