And a large tent in which a long sheet is stretched between main frames adjacent in the front-rear direction to form a curtain body.

  Conventionally, as a large tent such as a large temporary enclosure tent or a tent warehouse, for example, those disclosed in Japanese Patent Laid-Open Nos. 9-144323 and 9-144324, or the present applicant previously developed Those disclosed in Japanese Patent No. 5437164 and Japanese Patent No. 5971878 are known.

  FIG. 31 shows an example of a conventional large tent. The large tent is a gate-shaped main frame by a column member 60 arranged in a left-right facing manner and a mountain-shaped roof member 61 that connects upper ends of the left and right column members 60. A body 62 is formed, and a plurality of portal-type main bone bodies 62 are arranged at predetermined intervals in the front-rear direction. The frame structure 63 is formed by connecting with a connecting body (not shown), and a curtain body 64 that covers the entire frame structure 63.

  The curtain body 64 of the large tent is formed of a plurality of long sheets, a horizontally long triangular sheet, and the like. A long sheet is also provided between the main bone bodies 62 adjacent to each other in the front-rear direction. A horizontally long triangular sheet and a plurality of long sheets are stretched on both ends of the object 63, and the entire frame structure 63 is covered with the long sheet and the horizontally long triangular sheet to thereby form the curtain body 64. Try to form.

  The length of the long sheet stretched between the main frames 62 adjacent in the front-rear direction is the total length of the portal main frame 62 (the length of the left and right column members 60 and the length of the roof material 61). The length of the elongated sheet is formed to be substantially the same as the interval between the main bone bodies 62 adjacent in the front-rear direction. Furthermore, in both ears of the long sheet, it is slidable in the guide groove of a long sheet extending rail (not shown) provided outside the column member 60 and the roof material 61 of each main frame body 62. A flexible rope-like retaining portion to be inserted into each is provided.

  By the way, in a conventional large tent, when a long sheet is stretched between main frames 62 adjacent in the front-rear direction, first, the sheet is folded into a long sheet wound in a roll shape or a zigzag shape. The long sheet is placed at one lower end (position near the lower end of the left or right column 60) between the main frames 62 adjacent in the front-rear direction, and then a wire is attached to the front end of the long sheet. A hanging tool (not shown) such as a rope or a belt is attached, and then a long sheet extending rail (not shown) provided outside the column member 60 and the roof material 61 of the main body 62 adjacent in the front-rear direction. ) Is slidably inserted into the guide groove on both ends of the long sheet, and in this state, the suspension attached to the end of the long sheet is pulled up with a winch or crane, etc. And remove the long sheet By going sequentially inserted into the guide groove of the preparative tensioning rail, so that for tensioning the elongated sheet between the main bone body 62 adjacent to the front-rear direction.

  However, in the conventional large tent, the long sheet stretched between the main bone bodies 62 adjacent in the front-rear direction is formed to have substantially the same length as the entire length of the portal main bone body 62. The length of the long sheet is considerably long and the weight is also very heavy, making it extremely difficult to handle.

  Further, when the length of the long sheet is long, when inserting the retaining portions provided at both ends of the long sheet into the guide groove of the sheet extending rail provided in the main frame 62, The frictional resistance between the long sheet retaining portion and the seat tension rail becomes extremely large, and the long sheet retaining portion can be smoothly and smoothly inserted into the guide groove of the seat tension rail. Disappear.

  As a result, in the conventional large tent, it takes a lot of time and labor to stretch the long sheet between the main frames 62 adjacent to each other in the front-rear direction, which increases the assembly cost. there were.

  In order to solve the above-described problem, for example, if the long sheet is cut along the width direction at the intermediate portion and divided into two in the longitudinal direction, the length of the long sheet per sheet is significantly shortened. At the same time, the weight of the long sheet is reduced and the handling becomes easier. Also, since the length of the long sheet per sheet is short, the frictional resistance between the long sheet retaining portion and the sheet stretching rail is reduced, and the long sheet retaining portion is stretched. Can be inserted relatively smoothly and smoothly into the guide groove of the rail.

  However, in a large tent in which the long sheet is divided into two in the longitudinal direction, the long sheet can be easily and easily stretched in a relatively short time, but the upper ends of the two long sheets Since a gap is formed between them, there is a problem that rainwater leaks from the gap or dust in the large tent flows out to the outside.
