摘要： PURPOSE:To contrive the reduction of a workload by supporting one end of a structural material on the upper end of a shielded side wall, temporarily connecting the other end thereof to a reactor containment vessel and releasing the temporary connection after placing concrete on the structural material to solidify. CONSTITUTION:At first, the work of a reactor containment vessel 12 and a shielded side wall 15 is performed after the execution of a mat 10. One end of a steel frame beam 18 is supported to fix on a steel frame column 17 buried on the upper end of the side wall 15 and a mold form 19 is supported on the beam 18 by a separator 20. A plate 25 is attached to the end part of the side of the vessel 12 of the beam 18 and a female shear lug 23 is connected to the plate 25. Next a male shear lug 22 and the female lug 23 attached to the vessel 22 are attached each other temporarily. Next concrete is placed on the form 19 and around the circumference of the beam 18. After concrete of a shielded wall ceiling floor 16 is solidified, the temporary connection of the lugs 22, 23 is released and the function of a shear lug 21 essentially needed is imparted.

摘要： PURPOSE: To reduce the quantity of temporary construction materials necessary for supporting the weight of a partition floor and curtail man-days and the working period for a construction work by supporting the lower part of a liner at the underface of a partition floor and placing concrete while making use of the compressibility of water filled in the lower chamber of a container. CONSTITUTION: A central mat 6 whose bottom is lined with a bottom liner 7 and the outer peripheral wall is lined with a side face liner 8 to form a concrete container 2. A container lower chamber 5 is provided so that the internal face wall in which the partition plate 3 of the ceiling is lined with a partition underface liner 10 is made airtight by a pressure vessel pedestal 9 and a vent tube 11. A supply water sluice valve is opened to fill water in the container lower chamber 5 and the upper weight is supported by making use of the compressibility of water at the underface of the partition floor underface liner 10. In this state, concrete for the partition plate 3 is placed. When the concrete has been solidified, a sluice valve 24 for drain is opened to discharge water. In this way, the work to support the partition plate 3 from above is simplified and hence man-days can be reduced.

摘要： PURPOSE:To eliminate the use of long-sized temporary supporting materials and to shorten the period of work by placing concrete for a partition wall while allowing a steam relief safety discharge pipe erected in a pressure suppression chamber to receive the load from a horizontal beam in the lower part of the partition floor. CONSTITUTION:The pressure control chamber 14 is constituted of a central mat 10, a bottom liner 13, a side face liner 2, the partition floor 4 and a linear 3 for the rear face of the partition wall, etc. The foundation of the steam relief safety discharge pipe 8 is constituted prior to the installation of the central mat 10. The concrete for the central mat 10 is then placed and after a quencher 9 is installed by an anchor bolt, the discharge pipe 8 is fixed by welding. A temporary post 6 is then erected to the upper part of the pipe 8 to join the pipe and the top end of the post is fixed by welding to the temporary horizontal beam 5. The beam 5 is installed to support the liner 3 for the rear face of the partition wall via mating hardware 16 and a supporting bracket 19. The concrete for the partition wall 4 is then placed. The load at the concrete placement of the partition floor 4 is born by the bracket 19, the hardware 16 and the pipe 8.
