摘要： PROBLEM TO BE SOLVED: To improve the construction property and prevent the occurrence of a crack in a wall due to excessive stress by providing a fitting groove on a precast beam, mounting a precast wall in the fitting groove in such a manner that it can slide, and filling mortar in the fitting groove to bond them. SOLUTION: A precast wall 2 is slidably mounted in a fitting groove 10 provided in a precast beam 1 which is a heavy structure to perform positioning of the beam 1 and the wall 2 due to play in a slide section. Next, a steel plate 12 is provided between the wall 2 and the fitting groove 10 and then mortar 14 is filled therebetween to bond and fix them so that a necessity of the mounting work such as welding, tightening bolt is eliminated. Moreover, instead of the steel plate 12, synthetic resin sheet such as Teflon sheet and a viscous elastic body such as asphalt are used to absorb earthquake energy. Consequently, it is possible to improve the mounting work property greatly and prevent the occurrence of a crack on the precast wall 2 even when an earthquake occurs.

摘要： PROBLEM TO BE SOLVED: To improve the workability, and to shorten the construction period by constructing a lower structure and a cylindrical wall under a housing container, and arranging a top slab and a pool, which are integrally assembled with each other on a frame, on the cylindrical wall under the housing container. SOLUTION: A base rock G is excavated so as to form a lower structure 1a of a nuclear reactor building 1 and a cylindrical wall 3a of a lower structure of a housing container 3, and simultaneously, a frame 15 of steel is provided in a side of the building 1 during the construction. Thereafter, a top slab 4 and a pool 5 are integrally assembled with each other on the temporary frame 15, and the unified unit is slid from the frame 15 by a jack. Continuously, a chill tank 16 is removed, and the unit is integrally connected to the lower structure 1a of the building 1 and the cylindrical wall 3a, and the frame 15 is disassembled for elimination. Continuously, a pressure container 4 is provided inside of a housing container 3, and a shield wall 18 is formed in the top of the container 3, and furthermore, a side wall 7 of the slab 4 is formed with a cover 19. With this structure, construction period is shortened, and high lift work is reduced by assembling the top slab 4 and the pool 5 on the ground so as to improve the safety of the work.

摘要： PROBLEM TO BE SOLVED: To build a roof body, with which a construction work space is covered, by using a regular building structure material, to cope with conveying-in of a material from the outside by an external lift, and to perform a building work without being influenced by weather. SOLUTION: A preceding frame 4 is precedingly built at a preceding construction area 3 and a rail body is arranged at the preceding frame 4. An opening closing roof 13 built in such a manner that a plurality of curing roofs are caused to span between the rain bodies is built between the preceding frame 4. The opening closing roof 13 is transferred, in order, to an upper story along with preceding construction of the preceding frames 4 to a given height. A structure in a subsequent construction area 2 is built under the opening closing roof 13 transferring to above.

摘要： PURPOSE:To make it possible to save manpower of labor intensive type exterior wall construction work and proceed with the exterior wall construction work systematically without any restrictions on lifting operation of the exterior wall work. CONSTITUTION:A horizontal beam 4 is mounted to the upper end of an expansion type mast 1 where a horizontally movable lifting facility 6 is installed along the lower part of the beam 4, thereby constituting an exterior wall construction expansion type mast at the tip of the paired expansion type masts 1 installed side by side so as to support suspendingly and lift freely a unit scaffolding 12, which covers a specified construction unit area of the exterior wall which connects integrally a specified number of unit scaffoldings in the extension direction and the height direction of the exterior wall. A plurality of paired expansion type masts 1 are installed with a specified spacing in the extension direction of the exterior wall to be constructed and erected on a floor 7 inside the exterior wall, thereby supporting suspendingly the unit scaffoldings 12 outside the exterior wall in the lifting facility 6 at the tip of the beam of each of the paired expansion type masts 1. The expansion type masts 1 are expanded and changed from the lower floor to the upper floor one by another, thereby constructing the exterior wall of a building between the unit scaffoldingly 12 outside the exterior wall and the scaffoldings assembled inside the exterior wall.
