摘要： PROBLEM TO BE SOLVED: To provide a high-performance stabilization liquid composition used for drilling method using a stabilization liquid for drilling of hole or groove so as to enable to perform drilling under severe conditions, e.g. drilling of a hole or a groove under underground water conditions having such high pressurized water head as to naturally spout or drilling of hole or groove to overconsolidated clay ground of diluvium layer or ground having a large flow rate of underground water and construct earth drill pile excellent in long-term disperse stability performance and concrete replacing property and continuous underground wall, etc. SOLUTION: This high-performance stabilization liquid composition having a high specific gravity is obtained by compounding kibushi-clay and/or kaolin mineral composed of kaolin as clay mineral and has >1 liquid specific gravity. For example, the stabilization liquid is obtained by compounding 1 m3 city water with 40 kg bentonite, 360 kg kibushi-clay, 2 kg CMC and 2 kg dispersing agent.

摘要： PURPOSE:To improve the safety of working and workability by attaching apparatuses such as air-conditioning apparatuses and electric apparatuses at a position close to the ground, finishing a ceiling, and moving the ceiling of a large- space structure to the specified height with lifting means, and fixing the ceiling. CONSTITUTION:This method is different from a conventional method, wherein the ceiling of the structure having the large space is constructed by providing scaffolds. Apparatuses, which are provided at the ceiling, and ceiling finishing materials are assembled on a bed frame 5 on a plane, which is slightly smaller than the planar periphery of a structure A. Thus, the apparatuses and the like are attached in the vicinity of the ground. Then, the frame is lifted through suspending members 4 with lifting devices 1 such as chain blocks, which are suspended from the ceiling (b) through wires 2. The suspending members 4 and suspending members 4a of the bed frame 5 are connected. After the apparatuses, which are provided at the specified positions, are connected to a main-body facility in this way, the lifting devices are removed.

摘要： PURPOSE:To save labor and the manufacturing cost and to enhance the structural reliability by laying a precast concrete plate which has been previously manufactured, between beams, and by placing concrecte in cut-out parts in the peripheral edge part thereof. CONSTITUTION:Truss type main beams 3 are laid in the longitudinal direction of small width rectangular steel plates 2, a number of floor plates 1 each composed of a combination of steel floor plates 1a through 1d integrally incorporated with floor reinforcement integral with the steel plate 2 are used as a floor die frame, the number corresponding to that used for one unit. Further, force distributing reinforcement 4 is laid between the main beams 3, and then concrete 5 is placed so as to form a PC floor board A having cut-out parts 6 in the peripheral edge part thereof. The PC floor boards A are transported to a jobsite, and are then laid between beams B while auxiliary reinforcement 8 is welded between the cut-out parts 6, 6 of the adjacent floor boards A, and then concrete C is placed in the cut-put parts 6, 6 so that the floor boards A are jointed to each other. Thereby it is possible to construct a floor only by joining the joint parts of the PC floor panels to each other.
