摘要： PROBLEM TO BE SOLVED: To generate a crack in a specific place easily and positively so as to prevent a crack from being generated in an optional direction in an unexpected place. SOLUTION: Three knotless reinforcements 1A, 1B, 1C are embedded in a thin wall part held between joint grooves 21, 21 of a reinforced concrete wall 11, at specified spaces parallel with the joint grooves 21, 21. Within a period from the time of concrete temperature becoming maximum due to heating reaction of hydration until the time of a temperature crack being generated to the reinforced concrete wall 11 by expansion and contraction caused by heating reaction of hydration, a current is applied to the reinforcements 1A, 1B, 1C by an AC power unit 2 to heat the reinforcements 1A, 1B, 1C. Tensile stress vertical to a plane including the reinforcements 1A, 1B, 1C is generated to the thin wall part between the joint grooves 21, 21 of the reinforced concrete wall 11 so as to generate a crack to the thin wall part.

摘要： PURPOSE:To lift or lower roof frames independently from a building not to hinder the carrying-in of materials and provide the flexibility. CONSTITUTION:A lift base 3 can be lifted/lowered by a lifting/lowering device mounted on it via a stanchion 2. A roof frame 4 is divided into two and can be folded by hinges, and one side opposite to the hinge side is fitted to the lift base 3 with other hinges. An opening/closing device 5 mounted on the lift base 3 folds/spreads and opens/closes the roof frame 4. When the stanchion 2 is erected independently from a building 8, the roof frame 4 can be lifted or lowered independently from the building 8. The roof frame 4 can be folded not to hinder the carrying-in of materials. The angle of a pair of roof frames 4, 4 is adjusted, the number of temporary roofs arranged in parallel is adjusted, thus the flexibility is provided.

摘要： PURPOSE:To make narrow a gap between a column and a slab surface and to make it possible to prevent a column side from stains caused by grout. CONSTITUTION:A grout injection hole 20 extending from a column side 1a to the approximately central part 21 of a column bottom 1b and a hole connecting to the upper ends of sleeves are bored in a precast concrete column (hereinafter referred to as 'column') 1 in advance, and a discharge pipe 15 projected from the column side is inserted into the hole. The discharge pipe 15 is positioned lower than a grout injection port 19. Down stair column main bars 12 are inserted in a sleeve 11, and the column 1 is erected by leaving out a gap C from a slab surface 3a. After that, a grouting form 17 is installed around the lower end of the column 1 through a gas permeable material 18 so as to surround the gap C. Then, grout is injected into the gap C and sleeve 11 through a grout injection port 19.
