PROTECTIVE SHEET AND PROTECTIVE SHEET STRUCTURE
PROBLEM TO BE SOLVED: To provide a protective sheet which has a ventilation opening formed for discharging wind pressure when a strong wind acts thereon, and closes after a strong wind.SOLUTION: A protective sheet 20 is provided along an outer surface of a temporary scaffold 1. The protective sheet 20 includes a slit 30 through which the wind passes and a plurality of rubber strings 40 which open/close the slit 30. The rubber strings 40 make an opening amount of a central part of the slit 30 larger than an opening amount of an end part. According to the present invention, when a strong wind acts on the protective sheet 20, the slit 30 through which the wind passes opens, and after a strong wind, the slit 30 is closed by the rubber strings 40.SELECTED DRAWING: Figure 6
【課題】強風が作用した際には、風圧を逃がす通風用開口が形成され、強風後に閉鎖する防護シートを提供すること。【解決手段】防護シート２０は、仮設足場１の外面に沿って設けられる。防護シート２０は、風が通るスリット３０と、このスリット３０を開閉する複数のゴム紐４０を備える。これらゴム紐４０は、スリット３０の中央部の開口量を端部の開口量よりも大きくする。この発明によれば、強風が防護シート２０に作用すると、風を通すスリット３０が開いて、強風後にはゴム紐４０によりスリット３０が閉鎖される。【選択図】図６
