PURPOSE:To prevent the diffusion of noise and light by partitioning a high and wide large space to each desired space. CONSTITUTION:A number of driving-out/taking-up devices are arranged at a number of places on a large roof, and each suspending member 18 is connected with each- driving out/taking-up device, and an extensible/contractible type frame work 20 is installed on the ground 12, spectator's seat, etc., under the driving-out/taking-up device, and the suspending member 18 of the driving-out/taking-up device is connected in a demountable manner at the upper part of the extensible/contractible type frame work 20. The extensible/contractible frame work 20 is extended upwardly by pulling up the upper part of the extensible/contractible frame work 20 by the operation of the driving-out/taking-up device, and a partitioning wall is formed from the extensible/ contractible frame work 20 in extended state and a wall member 23 installed on the frame work 20. A ceiling 15A connected with the suspending member 18 of the driving-out/taking-up device is lowered to the nearly equal height to the upper end of the extensible/contractible frame work 20 in extended state. Accordingly, the oscillation of the partitioning wall 8 by wind, etc., can be prevented even if the inside space of a large-sized building is formed so as to permit the inflow of the atmosphere. |
