摘要： PURPOSE:To make it possible to construct an artificial skiing slope having a sufficient distance for descent by preparing a concrete bottom board along a seabed inclining downward as it becomes away from the coast line, and by preparing banks at three sides of the periphery of the bottom board. CONSTITUTION:Over a seabed that gradually inclines downward as it becomes away from the coast line, a concrete bottom board 1 is constructed along undulations of the seabed. Then banks 2 encircling the periphery of the bottom board 1 from three sides are constructed and seawater is shut off thereby. To the seabed under the bottom board 1, earth anchors 5 and 5 are planted with their heads anchored to the underside of the bottom board 1 so that the bottom board 1 can be prevented from floating by buoyancy. Thereby resistivity against earthquake and wind load can be secured with easy construction, while maintenance and control of artificial snow becomes easy.

摘要： PURPOSE:To make the base of a pile reducible as well as to aim at reduction in body cost drilling plural pile holes so as to partially overlapped with each other, and driving each pile in these pile holes in guiding them each other. CONSTITUTION:A pile hole 8, with a sectional form made up of connecting two circular holes being partially overlapped, is formed by putting two augers 3, 3, insomuch that each drilling radius of these two augers 3, 3 is partially overlapped or so. Then, a pile 10 is driven in a one-side circular part 8a of the pile hole 8, and with this pile 10 set down to the guiding one, another pile 12 is driven in another side circular part 8b of the pile hole 8 via a spacer 11 attached to the peripheral side. With this constitution, since these two piles 10, 12 are driven in the hole as being approximated to each other, supporting force per pile can be increased.

摘要： PROBLEM TO BE SOLVED: To provide a joint structure of wooden members which can easily join a through pillar and beams to be jointed to both the sides of the pillar and surely and firmly join the through pillar and the beams of the opposite sides by a continuous beam effect. SOLUTION: A pipe-shaped nut 7 is embedded in a joint of a through pillar 1 and beams 2 and connecting bolts 10 in the end parts of the beams 2 respectively. The end parts 10b on the through pillar side of the connecting bolts 10 are screwed in the end parts of the pipe-shaped nut 7 respectively and connecting nuts 12 are screwed on the end parts on the beam sides, so as to joint the through pillar 1 and the beams 2 on the opposite sides respectively. The pipe-shaped nut 7 is inserted and embedded in a pipe-shaped nut insertion hole 3 formed in the joint of the through pillar 1 and the beams 2, while the connecting bolts 10 are inserted and embedded in connecting bolt insertion holes 5 formed in the end parts of the beams 2. Moreover, connecting bolt insertion pipes 9 are embedded in the connecting bolt insertion holes 5 and the connecting bolts 10 are inserted through these connecting bolt insertion pipes 9 and embedded.

摘要： PURPOSE:To improve workability by a method wherein push up devices raised by a measuring worm method are disposed adjacently to all the columns of a steel frame structure, and after a regular constructing beam is placed thereon and one story at a time is built on a ground, the structure is pushed up, in order. CONSTITUTION:A push up device 16 elevated in a way that upper and lower frames 3 and 4 are alternately engaged between a pair of temporary erected stays is arranged adjacently to each column 7 of a structure. Beams 6 for the floor of a topmost story structure are placed on the frame 3 brought into a lowermost position to build the steel frame of a topmost story. After a roof slab 20, an outer wall 20, and a deck material 21 for a next lower story are constructed, a structure equivalent to one full story is pushed up and concreting for the concrete floor of the story is executed. Columns 7a for a lower story are erected and after upper and lower parts are finely adjusted by jacks 23, the frames 3 and 4 are lowered. Beams are placed on the frame 3 and a corresponding story is built and pushed up. Further, after all stories are built in a similar manner described above, the devices 16 are disassembled for removal. This method and constitution executes construction without using temporary support beams and improves precision, safety, and efficeincy.

摘要： PURPOSE:To improve efficiency of construction by assembling the building frame on the uppermost storey, pushing up one storey part by means of push-up devices so as to assemble the building frame of next storey, and pushing up one storey part in order. CONSTITUTION:A roof of a building and the building frame such as beams, floors, and walls of uppermost storey are assembled on the ground part as a basement 10, and a plurality of push-up devices 20 are arranged between the beams between the pillars of the building frame and the basement 10. Temporary receiving beams 29 are drawn out, jacks 28 are extended, and a building is pushed up by one stroke through an upper load receiving beam 26. Next upper rotary nuts 24 are rotatingly elevated, the upper load receiving beam 26 is supported and fixed with temporary pillar bodies 21, and the jacks 28 are contracted so as to rotatingly elevate lower rotary nuts 25. Hereby, the upper load receiving beam 26 and the lower load receiving beam 27 are alternately elevated inch-worm-likely so as to push up the building of one storey part, and construction speed can be improved.
