When the long sheet 54 a is stretched between the main frames 52 adjacent in the front-rear direction, the long sheet 54 a is stretched from the vicinity of the top of the roof material 51 of the main frame 52 toward the lower end of the column member 50. I try to set it up.

  That is, in a large tent, when the long sheet 54a is stretched between the main bone bodies 52 adjacent in the front-rear direction, first, the long sheet 54a folded in a zigzag shape is first removed by a crane or the like. 52 is lifted up to the vicinity of the top of the roofing material 51 and placed on a scaffolding plate or the like disposed near the top of the roofing material 51. Next, a plurality of workers in the vicinity of the top of the roofing material 51 receive a long sheet 54a. One end portion of the long sheet 54a is pulled out, and a rope-like retaining member 56 provided at both ears of the long sheet 54a is provided outside the column material 50 and the roof material 51 of the main bone body 52 adjacent in the front-rear direction. Is inserted into the guide groove of the sheet-like sheet extending rail 55 and then pulled along the sheet extending rail 55 while pulling out the folded long sheet 54a, and the long sheet 54a is pulled out. Stop member 56 By successively inserted into the guide groove of the over preparative tensioning rail 55, so as to stretched elongated sheet 54a between the main bone body 52 adjacent to the front-rear direction.

  However, in the large tent, when the long sheet 54 a is stretched between the main bone bodies 52 adjacent in the front-rear direction, the long sheet 54 a is positioned in the vicinity of the upper end of the sheet stretching rail 55 by the operator. The retaining member 56 of the long sheet 54a must be sequentially inserted into the guide groove of the sheet stretching rail 55 while supporting the sheet. There is a problem that it takes a lot of time and effort to insert into the guide groove of the rail 55, and it takes a lot of time and labor to stretch the long sheet between the main frames 52 adjacent in the front-rear direction. As a result, there was a problem that the assembly cost of the large tent was high.
