  • the anchor members are attached to the outer surfaces of the formwork, when the second plant structure members are moved along an inner surface of the formwork to install the second plant structure members, the second plant structure members do not collide with the anchor members including the removable tightening apparatuses used to install the second plant structure members and thereby the movement of the second plant structure members is not impeded. This enables the second plant structure members to be easily disposed in the composite integrated module 1 by using the anchor members including tightening apparatuses.
  • the anchor member 13 is disposed on the back surface of the wall steel plate 12 and the anchor member 20 is disposed on the back surface of the floor steel plate 19 and these anchor members do not protrude from the fronts of steel plates. Accordingly, an internal structure member that needs to be attached to at least two of the sidewall member 10 , floor member 16 , and ceiling member 21 , specifically the equipment 27 , can be easily disposed in the composite integrated module 1 . Concretely, when the underside of the installation frame 29 of the equipment 27 is moved horizontally, for example, near the top surface of the floor steel plate 19 , the through-holes formed in the installation frame 29 , into which the installation bolts 25 are inserted, can be easily aligned to the openings 35 formed in the floor steel plate 19 .
  • the equipment 27 can be easily attached to two surfaces of the composite integrated module 1 .
  • the anchor member 13 does not protrude into the inside of the wall steel plate 12
  • anchor member 20 does not protrude into the inside of the floor steel plate 19 .
  • the present embodiment can solve the problem with conventional installation of a plant facility in which foundation bolts are installed to a floor member and a wall member of a composite integrated module and these foundation bolts are used together with nuts to install the plant facility.
  • the installation bolts 24 and 25 are removed.
  • the equipment 27 can then be moved, enabling the maintenance and the inspection of the equipment 27 to be easily carried out. After the maintenance and the inspection of the equipment 27 have been carried out, it can be easily installed in the composite integrated module 1 as descried above. Force that is generated by tightening the installation bolts 24 and 25 can be transmitted to the concrete through the anchor members 13 and 20 .
  • the pillar steel frames 2 and first ceil steel frames 3 and module skids 11 support the ceiling member 21 , so these members can support the load of concrete poured on the deck plate 23 . Accordingly, concrete can be poured on the Q-deck 23 and outside the sidewall members 10 simultaneously, shortening a building period of the nuclear power plant. In particular, it becomes unnecessary to establish a period that has been required to wait until concrete poured outside the sidewall members 10 is hardened before concrete is poured into the ceiling section.
  • the embedded plate 31 A to which a plurality of anchor bolts 32 A (anchor members) 32 A is attached is directly fixed to the front surface of the module skid 11 , and the support member 33 attached to the embedded plate 31 A supports first plant structure members such as the pipe 34 or duct. Accordingly, when the composite integrated module 1 is transported, the loads based on the first plant structure members can be held by the module skids 11 .
  • the pipe 34 undergoes thermal expansion during an operation of the nuclear power plant. Due to this thermal expansion and the weight of the fluid flowing in the pipe 34 , the load applied to the pipe 34 is extremely larger than the load applied to the pipe 34 during transportation of the composite integrated module 1 .
  • the anchor bolt 32 A attached to the embedded plate 31 A and the module skid 11 are buried in the hardened concrete, the embedded plate 31 A being directly attached to the module skid 11 . Accordingly, in the present embodiment, since a support structure member, which includes the embedded plate 31 A, for supporting the pipe (or duct) 34 , and the tray is used, the first plant structure members, to which large loads are applied during a plant operation, such as the pipe (or duct) 34 and the tray can be easily supported.
  • a load applied to the first plant structure members (the pipe 34 and the like, for example) during a plant operation is transmitted through the support member 33 to the embedded plate 31 A and further transmitted to the module skid 11 and anchor bolts 32 A, which are buried in the concrete. Since the load is transmitted to the module skid 11 and anchor bolts 32 A in this way, the pipe 34 , to which a large load is applied during a plant operation, can be supported. Materials installed to reinforce the wall steel plate 12 can be substantially lessened.
  • a support structure member for this pipe may be attached directly to the front surface of the module skid 11 without using the embedded plate.
  • the positions of the wall steel plates 12 can be easily adjusted during the manufacturing of the composite integrated module 1 because adjacent two wall steel plates 12 are attached to the front surface of the module skid 11 so that the clearance G is formed between them.
  • the clearance G is also formed when the floor steel plate 19 is attached to the frame beams 17 and 18 , facilitating positional adjustment of the floor steel plate 19 .
  • Time taken to weld the wall steel plate 12 to the module skid 11 and to weld the floor steel plate 19 to the frame beams 17 and 18 can be substantially shortened, contributing reduction in time taken to manufacture the composite integrated module 1 .
  • the module skid 11 can be disposed outside the wall steel plates 12 and buried in the concrete of the nuclear reactor building, so the room 26 , which is internally formed, can be enlarged.
  • Each pillar steel frame 2 is attached to the floor member 16 , specifically to the frame beam 17 and the like by using the first floor steel frame 5 . Therefore, the lower end portion of the pillar steel frame 2 can be fixed directly to the floor member 16 , enabling the composite integrated module 1 to be easily transported.
  • the first floor steel frame 5 and second floor steel frame 6 are removed from the composite integrated module 1 when the composite integrated module 1 is placed at a predetermined position in an area in which a nuclear reactor building is constructed before concrete is poured outside the sidewall members 10 .
  • a point in time at which to start the pouring of concrete can be moved ahead, shortening a building period of the nuclear power plant.
  • the first plant structure member may be attached to the ceiling member (see FIG. 8 ), as described below.
  • This ceiling member 21 A has a plurality of frame member 46 , ceiling steel plate formworks 45 and an embedded plate 31 C.
  • the ceiling steel plate formworks 45 are used instead of the deck plate.
  • a plurality of frame members 46 extending in a direction orthogonal to the frame beam 22 is disposed on the frame beam 22 .
  • a plurality of ceiling steel plate formworks 45 disposed between the frame member 46 and frame beam 22 are welded to the frame member 46 in the same way as when the sidewall member 10 is attached to the wall steel plate 12 .
  • the embedded plate 31 C to which the anchor bolts 32 C extending upward are attached, is welded directly to an undersurface of the frame member 46 .
  • the support member 48 is disposed on the underside of the embedded plate 31 C, and at least one of the pipe, duct, and tray is attached to the support member 48 .
  • FIG. 8 shows a state that pipes (first plant structure members) 49 are attached to the support member 48 .
  • the adjacent two ceiling steel plate formworks 45 are fixed to the undersurface of the frame member 46 so that a clearance G is formed between the two ceiling steel plate formworks 45 as with wall steel plate 12 shown in FIG. 7 .
  • This type of support structure member can support the first plant structure member, which is supported by the ceiling member 21 A, to which a large load is applied during a plant operation.
  • the concrete is poured atop the ceiling steel plate formworks 45 .
  • the embedded plate 31 C can be attached to at least one of the frame members disposed on the sidewall member 10 , the floor member 16 and ceiling member 21 based on the arrangement of the first plant structure member in the composite integrated module.
