Abstract

A plant building (4) includes a building body (5) that has a first installation region (51) where a first rotary machine (2) is installed, a second installation region (52) where a second rotary machine (3) is installed, and a carrying in and out region (53) provided between the first installation region (51) and the second installation region (52) in a horizontal direction, a first overhead crane (6) that is disposed in the building body (5) and is capable of traveling above the first installation region (51) and above the carrying in and out region (53), and a second overhead crane (7) that is disposed at a height position different from a height position of the first overhead crane (6) in the building body (5) and is capable of traveling above the second installation region (52) and above the carrying in and out region (53).

First claim

The invention claimed is:

1. A plant building comprising:
a building body that has a first installation region where a first rotary machine is installed, a second installation region where a second rotary machine is installed, and a carrying in and out region provided between the first installation region and the second installation region in a horizontal direction;
a first overhead crane that is disposed in the building body and is capable of traveling above the first installation region and above the carrying in and out region; and
a second overhead crane that is disposed at a height position different from a height position of the first overhead crane in the building body and is capable of traveling above the second installation region and above the carrying in and out region,
wherein the first overhead crane is capable of traveling only above a region excluding the second installation region.

2. The plant building according to claim 1 , wherein the second overhead crane is capable of traveling only above a region excluding the first installation region.

3. The plant building according to claim 1 ,
wherein the first rotary machine has a first rotary shaft that is rotatable about a first axis,
the second rotary machine has a second rotary shaft that is rotatable about a second axis which is disposed so as to be parallel to the first axis and to be spaced apart from the first axis in the horizontal direction,
the first overhead crane is capable of traveling in the horizontal direction orthogonal to the first rotary shaft, and
the second overhead crane is capable of traveling in the horizontal direction orthogonal to the second rotary shaft.

4. The plant building according to claim 3 ,
wherein the first overhead crane has a pair of first traveling rails extending in the horizontal direction orthogonal to the first rotary shaft,
the second overhead crane has a pair of second traveling rails extending in the horizontal direction orthogonal to the second rotary shaft, and
the first traveling rails and the second traveling rails overlap each other in a vertical direction above the carrying in and out region.

5. The plant building according to claim 1 ,
wherein the second overhead crane is disposed at a position lower than the first overhead crane, and
the building body has
a first ceiling provided above the first overhead crane, and
a second ceiling provided above the second overhead crane at a position lower than the first ceiling.

6. The plant building according to claim 1 ,
wherein the first rotary machine has a first height dimension, which is a dimension from a floor of the building body in a vertical direction necessary for maintenance,
the second rotary machine has a second height dimension, which is a dimension from the floor of the building body in the vertical direction necessary for maintenance, and
the second height dimension is smaller than the first height dimension.

7. A plant comprising:
the first rotary machine installed in the first installation region;
the second rotary machine installed in the second installation region; and
the plant building according to claim 1 .

8. A multi-shaft combined-cycle plant comprising:
the plant building according to claim 1 ;
a gas turbine that is the first rotary machine installed in the first installation region;
a steam turbine that is the second rotary machine installed in the second installation region; and
a generator.

9. A plant building comprising:
a building body that has a first installation region where a first rotary machine having a first rotary shaft rotatable about a first axis is installed and a second installation region where a second rotary machine having a second rotary shaft rotatable about a second axis, which is disposed so as to be parallel to the first axis and to be spaced apart from the first axis in a horizontal direction, is installed;
a first overhead crane that is disposed in the building body and is capable of traveling above the first installation region in the horizontal direction orthogonal to the first rotary shaft;
a second overhead crane that is disposed at a position lower than the first overhead crane in the building body and is capable of traveling above the second installation region in the horizontal direction orthogonal to the second rotary shaft;
a first ceiling provided above the first overhead crane; and
a second ceiling provided above the second overhead crane at a position lower than the first ceiling,
wherein the first overhead crane is capable of traveling only above a region excluding the second installation region,
the first overhead crane has a pair of first traveling rails which extends in the horizontal direction orthogonal to the first rotary shaft in a state of being parallel to each other, and
the second overhead crane has a pair of second traveling rails which extends in the horizontal direction orthogonal to the second rotary shaft in a state of being parallel to each other.

10. The plant building according to claim 9 , wherein the first traveling rails and the second traveling rails are disposed so as to overlap each other in a direction where the first traveling rails extend, when seen from above in the vertical direction.

11. The plant building according to claim 9 , wherein the building body has a carrying in and out region inside thereof.

12. The plant building according to claim 11 , wherein the carrying in and out region is region provided between the first installation region and the second installation region in a horizontal direction.

13. The plant building according to claim 9 , wherein the second overhead crane is capable of traveling only above a region excluding the first installation region.
