It is related to a large tent in which a long sheet is stretched between each main skeleton adjacent to each other in the anterior-posterior 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 Application Laid-Open No. 9-144323 and Japanese Patent Application Laid-Open No. 9-144324, or those developed by the applicant earlier. Those disclosed in Japanese Patent No. 5437164 and Japanese Patent No. 5971878 are known.

FIG. 31 shows an example of a conventional large tent, in which the large tent has a gate-shaped main frame formed by a pillar 60 arranged so as to face each other and a chevron roofing material 61 connecting the upper ends of the left and right pillars 60. A body 62 is formed, and a plurality of portal-shaped main skeletons 62 are arranged at predetermined intervals in the anterior-posterior direction, and portal-shaped main skeletons 62 adjacent in the anterior-posterior direction are provided as muscles, girders, etc. It is composed of a skeleton structure 63 formed by connecting with a connecting body (not shown) and a curtain body 64 covering the entire skeleton structure 63.

The curtain body 64 of the large tent is formed of a plurality of long sheets, horizontally long triangular sheets, and the like, and a long sheet is provided between the main skeletons 62 adjacent to each other in the anteroposterior direction, and a skeleton structure is provided. A horizontally long triangular sheet and a plurality of long sheets are respectively stretched on both end faces of the object 63, and the entire frame structure 63 is covered with the long sheet and the horizontally long triangular sheet to cover the curtain 64. I try to form it.

The length of the long sheet stretched between the main bones 62 adjacent to each other in the anteroposterior direction is the total length of the portal-shaped main bone 62 (the lengths of the left and right pillars 60 and the length of the roof material 61). The length is substantially the same as the total length), and the width of the elongated sheet is formed to be substantially the same as the distance between the main bone bodies 62 adjacent to each other in the anterior-posterior direction. Further, both ears of the long sheet can be slidably slid into the guide grooves of the long sheet tensioning rail (not shown) provided on the outside of the pillar material 60 of each main frame 62 and the roof material 61. Each is provided with a flexible rope-shaped retaining portion to be inserted into the.

By the way, in the conventional large tent, when the long sheet is stretched between the main skeletons 62 adjacent to each other in the anteroposterior direction, first, the long sheet wound in a roll shape or folded in a zigzag shape. A long sheet is placed at one lower end between the main skeletons 62 adjacent in the anterior-posterior direction (a position near the lower end of the pillar 60 on the left or right side), and then a wire is placed on the tip of the long sheet. A hanging tool such as a rope or a belt (not shown) is attached, and then a long seat tensioning rail (not shown) provided on the outside of the pillar 60 and the roofing material 61 of the main frame 62 adjacent in the front-rear direction. ), The retaining parts provided on both ears of the long sheet are slidably inserted, and in this state, the hanger attached to the tip of the long sheet is pulled up with a winch or crane. By sequentially inserting the retaining portion of the long sheet into the guide groove of the sheet tensioning rail, the long sheet is stretched between the main skeletons 62 adjacent to each other in the front-rear direction. ing.

However, in the conventional large tent, since the long sheet stretched between the main skeletons 62 adjacent to each other in the anteroposterior direction is formed to have substantially the same length as the total length of the portal-shaped main skeleton 62. The length of the long sheet is considerably long, and the weight is also quite heavy, which makes it extremely difficult to handle.

Further, if the length of the long sheet is long, when the retaining portions provided at both ends of the long sheet are inserted into the guide grooves of the seat tensioning rail provided on the main frame 62, The frictional resistance between the retaining part of the long sheet and the rail for attaching the sheet becomes extremely large, and the retaining portion of the long sheet can be smoothly and smoothly inserted into the guide groove of the rail for attaching the sheet. It disappears.

As a result, in the conventional large tent, it takes a lot of time and labor to stretch the long sheet between the main bones 62 adjacent to each other in the front-rear direction, and there is a problem that the assembly cost becomes high. there were.

To solve the above-mentioned problems, for example, if a long sheet is cut along the width direction at an 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 becomes lighter, which makes it easier to handle. In addition, since the length of each long sheet is short, the frictional resistance between the long sheet retaining part and the sheet tensioning rail is also small, and the long sheet retaining part is stretched. It can be inserted relatively smoothly and smoothly into the guide groove of the rail.

However, in a large tent in which a 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 on the other hand, the upper end portion of the two long sheets. Since a gap is formed between the gaps, there arises a problem that rainwater leaks from the gap or dust or the like in a large tent flows out to the outside.

Japanese Unexamined Patent Publication No. 9-144323 Japanese Unexamined Patent Publication No. 9-144324 Japanese Patent No. 5437164 Japanese Patent No. 5971878

The present invention has been made in view of such problems, and an object of the present invention is to form a long sheet when a long sheet is stretched between gantry-shaped main bones adjacent to each other in the anterior-posterior direction. It is an object of the present invention to provide a large tent in which a sheet can be easily and easily stretched, and rainwater can be prevented from leaking from the roof or dust and the like in the large tent can be prevented from flowing out to the outside.

In order to achieve the above object, in the large tent according to claim 1 of the present invention, a gate-shaped main skeleton provided with left and right pillar materials and a mountain-shaped roofing material is arranged at predetermined intervals in the front-rear direction. Along with the installation, the main skeletons adjacent to each other in the anteroposterior direction are connected by a plurality of connecting bodies to form a skeleton structure, and the left and right pillars except near the top of the roofing material of each main skeleton of the skeleton structure. In the guide groove of the long sheet tensioning rail provided on the outside of the material and roofing material, the long retaining parts provided on both ears of the long sheet are slidably inserted, and at least front and rear. Between each main skeleton adjacent to each other in the direction, one long sheet or a plurality of sheets are stretched from the vicinity of the top of the roofing material to the lower end of the left pillar material and the lower end of the right pillar material. It is a large tent in which long sheets are stretched in series to form a curtain body, and is arranged along the roof of the skeleton structure, and the ridge portion of the skeleton structure is above the roof body. The roof cover is provided with a plate-shaped roof cover that covers from the roof , and the roof cover is composed of a plurality of cover bodies formed in a rectangular shape, and each cover body is arranged in series along the ridge of the skeleton structure. At the same time, it is characterized in that it is provided with a plurality of locking pieces that are locked and fixed to a rail fitting that attaches the seat tensioning rail to the roofing material .

The large tent of the present invention has one length each from the vicinity of the top of the roofing material to the lower end of the left pillar and the lower end of the right pillar between the portal-shaped main bodies adjacent to each other in the front-rear direction. Since the structure is such that a long sheet is stretched or a plurality of long sheets are stretched in series, the long sheet can be used as a conventional large tent formed to be approximately the same length as the total length of the main skeleton. In comparison, the length of the long sheet is shorter and the weight is lighter, which makes it easier to handle. In addition, since the long sheet is short, when the retaining parts provided on both ears of the long sheet are inserted into the guide grooves of the seat tensioning rail provided on the main frame, the long sheet is long. The frictional resistance between the sheet retaining portion and the seat tensioning rail is reduced, and the seat retaining portion of the long sheet can be smoothly and smoothly inserted into the guide groove of the seat tensioning rail.
In particular, in a large tent in which a plurality of long sheets are stretched in series from the vicinity of the top of the roofing material to the lower end of the pillar material, the length of one long sheet is shorter. Therefore, the frictional resistance between the retaining portion of the long sheet and the guide groove of the seat tensioning rail becomes smaller, and the retaining portion of the long sheet can be inserted into the guide groove of the seat tensioning rail. It can be performed even more smoothly and smoothly.
As a result, in the large tent of the present invention, a long sheet can be easily and easily stretched between the main bone bodies adjacent to each other in the anteroposterior direction in a relatively short time, and the long sheet is stretched. It is possible to reduce the assembly cost without requiring a great deal of time and labor.

Further, since the large tent of the present invention is arranged along the ridge of the skeleton structure and has a plate-shaped roof cover that covers the ridge portion of the skeleton structure from the upper side of the curtain body, it is adjacent in the front-rear direction. It is possible to prevent rainwater from leaking from the gap between the upper ends of the left and right elongated sheets stretched between the main skeletons, or to prevent dust and the like in a large tent from flowing to the outside.

Further, in the large tent of the present invention, since the roof cover is formed by arranging a plurality of cover bodies in series, it can be made smaller by disassembling the roof cover, and it is easy to transport to the site. It can be done easily, the storage space is small, it is convenient for storage, and the roof cover of the desired length can be formed by changing the number of covers arranged in series, which is extremely convenient. Is. Moreover, since the waterproof tape is attached to the end portions of each cover body adjacent to each other in the front-rear direction so as to straddle the waterproof tape, it is not said that rainwater leaks between the cover bodies adjacent to each other in the front-rear direction.

Further, in the large tent of the present invention, since each cover body is provided with one or a plurality of reinforcing ribs on its outer surface, the shape of the large tent is less likely to be deformed even when an external force is applied, and the roof cover is deformed. It is possible to prevent twisting and twisting.

Further, in the large tent of the present invention, since the reinforcing ribs of each cover body are formed with a plurality of hanging holes into which the hanging tools are inserted and locked, each cover body can be easily lifted by a crane or the like.

Further, in the large tent of the present invention, since each cover body is provided with a plurality of locking pieces that are locked and fixed to the rail fittings that attach the seat upholstery rails to the roofing material, the tent has a frame structure. It becomes easy to install.
