TEMPORARY OUTER FENCE STRUCTURE USING SHEET

PROBLEM TO BE SOLVED: To facilitate construction work by installing two rails parallel to each other on a ceiling part, placing between the rails a plurality of cross girders each having wheels mounted on both ends, and laying a sheet over sheet connecting members secured to the cross girders. SOLUTION: Two rails 1 are placed parallel to each other on a ceiling part for a working space in a construction site, and a plurality of cross girders 2 each having wheels 5 mounted on both ends are placed to extend between the raild Sheet connecting members 4 are fastened in place below the cross girders 2, a sheet is laid between the sheet connecting members 4 as a roof sheet 3a, and another sheet is mounted below the sheet connecting members 4 as a partitioning sheet 3b. When the cross girders 2 are slid to increase the intervals among the cross girders 2, the root sheet 3a is extended to cover the ceiling part, whereas if the intervals among the cross girders 2 are reduced the roof sheet 3a is folded like bellows. Thus the roof for the working space can be formed to freely open and close.
