    • PROBLEM TO BE SOLVED: To provide a reinforcement work execution method capable of carrying out safe and efficient work execution of horizontal reinforcements and using hook-part- shaped hoop reinforcements excellent in earthquake-resistance even in large-sized columnar structure and temporary reinforcement assembly jig used for the method. SOLUTION: A temporary assembly jig is used comprising a base frame installed in a work execution site, a plurality of columns 12 erectedly fixed detachably to the base frame, and a temporary assembly jig for temporarily assembling hoop reinforcements 1 to columns 12. In addition, a work execution site is provided with a temporary assembling process in which a temporary assembly 3 is assembled by temporarily assembling hoop reinforcements 1 to the columns 12 at set intervals through the temporary assembly device, a transfer process in which the temporary assembly 3 is installed from the top externally to the reinforcements 4 at the erected positions under the conditions that the engagement between the columns 12 and the base frame is released and the base frame is left, and a bonding process in which the transferred hoop reinforcements 1 of the temporary assembly 3 are bound to the reinforcements 4 at the closely built-up positions where work of erection is beforehand executed.

    • PROBLEM TO BE SOLVED: To provide a concrete house having an air-act structure in which indoor temperature difference in summer and in winter is not increased and power consumption for air-conditioning can be made largely lower than conventional devices. SOLUTION: External venting spaces 5 and internal venting spaces 6 mutually partitioned through heat-insulating panels are installed along the wall surface of a concrete wall constituting a house exterior wall on the main natural-lighting orientation side and the wall surface of the concrete wall configuring the house exterior wall on the reverse orientation side to a main natural-lighting orientation. Communication means mutually communicating with these spaces are mounted among these spaces, and an underfloor ventilation hole is formed to a ground beam 14 for a foundation section 13 in an openable and closeable manner. A blower 18 selectively introducing air introduced to an attic or the attic space of an uppermost floor through the external venting spaces and/or the internal venting spaces from the underfloor section of the first floor is secured to the attic or the attic space of the uppermost floor. Wall-rear venting spaces communicating with the attic space of the uppermost floor and the underfloor section of the first floor are formed into partition walls 19.

    • PROBLEM TO BE SOLVED: To provide an agitator for soil improvement, which enables efficient agitation in a short time, can secure great width capable of undergoing agitation at a time, enables the agitation and mixing without unevenness, and can miniaturize an actuator. SOLUTION: A rotating shaft 3 is provided so as to couple lower parts of vertically movable supporting parts 2 which are provided in parallel in a vertically longer shape at a prescribed interval; five thin quadrangular rotating tables 4a-4e are journaled on the rotating shaft 3 at prescribed intervals; agitating blades 5 are provided in such a manner as to be raised from quadrangular corner parts of the rotating tables 4a-4e and curved in the direction of the rotating shaft 3; a hydraulic motor 8 is provided in an upper part of the supporting part 2; sprockets 7 are provided in the rotating shaft 3 and an output shaft of the hydraulic motor 8; a chain 6 is made to run between the sprockets 7; and shallow stratum ground can be agitated with little resistance.

    • PROBLEM TO BE SOLVED: To facilitate the construction of a communicating tube and movement of the tube to the next construction place in a narrow place by titling a slide base having a driving shaft propulsion means and a driving shaft rotating means in the longitudinal direction and in the lateral direction. SOLUTION: A driving shaft 2 is inclined with a required gradient by forward and backward inclining cylinders 7, 8 to drill a mantle steel pipe until it reaches an underground pipe. After sediment in the steel pipe is discharged and the pipe is cleaned, a core is pulled out from the underground pipe to the ground by a core picking device with the same outer diameter as that of an internally fitted polyvinyl chloride inner pipe to be worked to a required shape. A stopper pipe is externally fitted to the polyvinyl inner pipe and fixed, the lower end of the stopper pipe is brought into contact with the outer periphery of the underground pipe, and the inner pipe projected part is inserted in a hole formed by pulling out the core to perform required mortar filling. If necessary, the driving shaft 2 is inclined in the lateral direction by a right and left inclining cylinder 5 to execute works. When the construction of the communicating pipe is completed, the construction device is moved to the next place by a hydraulic power shovel 9.

    • PURPOSE:To variably set the number of steps and the rise height according to a staircase different in floor height and by single form device. CONSTITUTION:A form device 12 for a staircase comprises a frame 13 where a guide groove 14 is formed in the longitudinal direction and plural molds 15 having a substantially U-shaped section, which are movably guided in the guide groove 14 of the frame 13 and erected on the frame 13 in such a manner as to oscillate, and further comprises a fixing means 16 for pressing the mold 15 to the adjacent mold 15 with a fixed angle alpha of inclination. At the time of manufacturing a staircase, the molds 15 are movably and continuously arranged in the longitudinal direction in the frame 13 according to the desired number of steps and the respective molds 15 are erected on the frame 13 in such a manner as to oscillate. The angle alpha of inclination of the mold 15 is variably adjusted to determine the step height h2, the molds 15 are fixed by the fixing means 16, and concrete 50 is thrown into a space partitioned by the inclined faces 30,31 of the frame 13 and the molds 15 to form a staircase.
