    • PURPOSE:To make it possible to give optimum prestress every optional section of a beam by coupling an intermediate sheath pipe placed between a fixed sheath pipe to be fixed to the beam and a fixed sheath pipe with a joint pipe. CONSTITUTION:A plurality of fixed sheath pipes 3 having an internal hole 4 respectively into which a PC steel is inserted are fixed lengthwise of a beam 1 at intervals each other. An intermediate sheath pipe 10 having the internal hole 4 into which the PC steel is inserted is provided between fixed sheath pipes 3 so that it is capable of loading and unloading. The fixed sheath pipe 3 and the intermediate sheath pipe 10 are coupled each other with a joint pipe 13 screwed into thread grooves 5 and 12 which are formed on the periphery of end section of the fixed sheath pipe 3 and the intermediate sheath pipe 10. Accordingly, the end section of the fixed sheath pipe 3 can be placed at an optional position of the beam 1, and optimum prestress can be given every optional section by a jack placed at the end section.

    • PURPOSE:To accelerate execution speed by fixing the perimeter of a membrane structure to the body section of a building, operating lifting devices by expending air-bags, and at the same time, by suspending them at a specific supporting point of suspension. CONSTITUTION:The outside column of a body section 1 as a supporting structure 2 is extended, and at the same time, a membrane structure 3 is formed by making a laminated coating material of synthetic resin on a basic cloth. Lifting devices 10 which the coating material of synthetic resin is applied to the basic cloth are so formed into baglike substances that they are capable of expansion and contraction. Then, the structure 3 is developed and expanded on the floor, the devices 10 are placed under a supporting point of suspension 4 in a state of contraction to connect to an air supply device, and at the same time, wires 6 anchored to each top 5 are wound around a winch W. The air is supplied to the devices 10, and at the same time, the which W is wound up to suspend the structure 3, and after a suspension roof 7 is completed, the devices 10 is contracted to remove. Accordingly, execution can be accelerated.
