    • PROBLEM TO BE SOLVED: To provide a large space roof structure with a simple structure, a roof supporting structural body unit used therefor and construction methods of them capable of being applied also to a membrane roof structure on which force blowing up caused by wind acts.
      SOLUTION: The end sections of an upper main cable 1 are fixed to the upper parts of struts 5 erected so as to oppose them at an interval, a large number of vertical subsidiary cables 3 supported by the upper main cable 1 are hung down at intervals in the longitudinal direction of the upper main cable 1, a projected and curved lower main cable is opposed to the upper main cable 1 at an interval and, at the same time, the roof supporting structural body unit 6 fixes the projected and curved lower main cable 2 at a lower part of the strut 5 on a place supported by a large number of vertical subsidiary cables 3. The roof supporting structural body units 6 are provided at regular intervals, a plurality of laterally subsidiary cables are arranged and are closely connected so that the laterally subsidiary cables 4 can be crossed over the lower main cable 2 in each roof supporting structural body unit 6 and that a roof finish 10 can be held by the lower main cable 2 and each laterally subsidiary cable 4.

    • PURPOSE:To perform an effective removal of toxic gases or powder dusts generated from a generating source by a method wherein a portable eddy-generating device is constructed by a double pipe of an inner circumferential pipe connected to a discharging fan and an outer circumferential pipe connected to an air feeding fan and then the outer circumferential pipe is provided with an air blowing port having a helical eddy-generating means. CONSTITUTION:One end of an inner circumferential pipe 1 of an eddy-generating device A is formed with an air suction port 2 and the other end of the inner circumferential pipe is provided with an air discharging port 3. The air suction port 2 of an outer circumferential pipe 4 is provided with an air suction port 5, and the air suction port 5 is provided with a plurality of air blowing nozzles 6 acting as an eddy- generating means. A side at the air discharging port 3 of the outer circumferential pipe 4 is provided with an air feeding port 7. Accordingly, the air feeding port 7 is connected to an air feeding fan and the air discharging port 3 is connected to the discharging fan. When both fans are operated, an eddy C is formed by a blowing air flow B got from the air blowing nozzles 6 and a suction air flow D is generated. With such an arrangement, toxic gases or powder dusts moved from or produced from a generating source can be removed instantly and effectively.
