PURPOSE:To facilitate an execution of works and maintenance with cost reduced by stretching ceiling members made out of flexible sheets by the use of fasteners, etc., set between ceiling back-up members adjacent with one another. CONSTITUTION:Exterior balconies 3 in a T-shape cross section are interposed at the both sides of multiple facility lines 2 in which floodlights, sprinklers, etc., are packaged, via suspension bolts 9, and a circular balcony 5 is concurrently installed onto a wall 4. In the second place. ceiling members 7 made of flexible sheets are provided, which are composed of cloth, vinyl cloth, etc., with desired properties such as transparency, flame resistance, ventilation, etc. Then, the ceiling members 7 are stretched by the use of open fasteners 11, etc., in places among the exterior balconies 3 and the circular balcony 5, and in spaces between the respective exterior balconies 3. In addition, maintenance accesses are provided, or an angle type ceiling is formed if required. This constitution permits joint sections to be reduced in number, and also permits the ceiling members to be mounted/demounted with ease, thereby making it possible to enhance an execution of works and maintenability with cost reduced. |
