Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bellows type tent structure such as a tent warehouse or a tent roof capable of reducing a volume ratio at the time of folding and a simple building structure using the same.

[0002]

2. Description of the Related Art Many bellows-type tent structures, such as warehouses, which have been used in the past, are often provided with two folds, as shown in FIG.
End frames 50 and 51 truss-assembled with horizontal connecting members and diagonal members as one set of frame members, and intermediate frames 52 and 52 disposed between the end frames 50 and 51.
Are connected by X-shaped horizontal connecting members 53 (hereinafter, referred to as X bar members), and the outer surface thereof is covered with a film material. The X bar member 53 has both lower ends of both oblique members fixed and the upper end slidable in the height direction of the frame.
1) and the intermediate frames 52, 52...
By moving the X-bar member 53 to the (50) side,
Is folded, and the tent structure is configured to be able to expand and contract or open and close.

[0003]

In the case of a bellows type tent structure of this type, the volume ratio at the time of folding (volume ratio with respect to the total expansion) is usually about 40%, that is, when the full tent structure is fully expanded in the expansion and contraction direction. In the case of a tent structure having a length of 10 m, the length when folded (tatami cost) is about 4 m.

For example, a semi-trailer or a trailer is usually used to carry a bellows-type tent structure having the above dimensions to the site. However, since the possible loading width of the semi-trailer or the trailer is 2.5 m, Most tent structures could not be transported in a folded state, and after each main frame was divided and transported to the site, it was assembled and installed again on site. Furthermore, in the case of a tent roof structure using a conventional X-bar member, the height of the frame must be determined in consideration of the slide length of the X-bar member 53, and the height dimension of the tent roof structure is reduced. There was also a problem that it could not be made smaller.

On the other hand, large equipment, large workpieces, etc.
Usually, production is carried out at a factory, and then the cargo is transported to the site by a large transport vehicle such as a trailer or a cargo ship.However, this method has problems such as high transportation costs and days of transportation. Had occurred. Therefore, in recent years, a tent warehouse was built in a local yard instead of a temporary factory,
Production of large-scale equipment and the like is performed locally.
However, when the height dimension of the product to be manufactured becomes large,
A sufficient eave height must be secured in the tent warehouse, but if the pillar height of the main frame is increased, problems such as the need to disassemble the main frame due to restrictions on the vehicle loading width may occur. Will do.

SUMMARY OF THE INVENTION Accordingly, a main object of the present invention is to provide a bellows type tent structure capable of reducing a volume ratio at the time of folding and easily transporting it in a folded state without disassembly by a transport vehicle such as a trailer. Another object of the present invention is to provide a simple building structure such as a warehouse or a factory, which has a high eave height and can be easily assembled on site by using this.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides an end frame provided at each end in the direction of expansion and contraction, and a plurality of intermediate frames provided between these end frames. A bellows-type tent structure which is constituted by a film material covering the outer surfaces of these frames, and which can be extended or contracted or opened and closed by moving one side of the end frame and the intermediate frame group to the other end frame side. In the object, each frame is connected to each other by a horizontal connecting rope in order to regulate the distance between the frames when the tent structure is fully deployed,
The present invention is characterized in that a stay leg member is provided for each frame to make the frame independent.

[0008] In the present invention, the X-bar member, which hindered the reduction of the volume ratio when the tent structure was folded, is eliminated, and instead, the frames are connected to each other to restrict the separation distance. A rope is provided, and a stay leg member is provided in addition to the main leg member so that each frame becomes independent. Therefore, at the time of folding, it becomes possible to move each frame to a state where it comes into close contact or approach, and the volume ratio at the time of folding can be significantly reduced. Further, the height of the tent structure can be set to a desired height because there is no need to consider the slide length of the X bar member.

According to the prototype by the present inventors, it is composed of an end frame and four intermediate frames, which will be described in an embodiment described later,
In the case of a tent roof structure having a length of about 10 m when fully deployed, it is possible to reduce the size when folded to almost less than 2.5 m (fold volume ratio 25%). as a result,
It can be mounted on a semi-trailer without disassembly,
The tent roof structure can now be directly mounted on a semi-trailer and transported in a simply folded state, so that transportation from the tent structure manufacturing plant to the site has been considerably reduced in labor.

[0010] In the tent structure, for example, a stay leg member may be provided on each of the front and rear surfaces of the frame so that the frame can be self-supported so as to prevent it from falling down in the front-rear direction. A running roller that is rotatable about a horizontal axis is provided on the side of the arm, and a running rail is a groove-shaped rail that opens in a lateral direction, and the running roller is inserted into the groove-shaped rail. By restricting both the upper and lower surfaces of the traveling roller, it is possible to prevent the stay from falling in the forward and rearward directions by one stay leg member. Furthermore, in addition to the running roller, the stay leg member is inserted into a rail groove formed along the direction of expansion and contraction, and is rotatable about a vertical axis that rolls while contacting the rail groove wall. It is also possible to provide a steady rest roller.

On the other hand, in the simple building structure using the bellows type tent structure, a frame scaffold is constructed to a predetermined height position in a rectangular frame shape in a plane, and a panel or a membrane material is formed on a side surface of the frame scaffold. To make the building wall surface, and the bellows type tent structure is installed at the top of the frame scaffold.

According to the simple building structure, a temporary factory or a temporary warehouse can be easily installed on the site by using a framework scaffold which is extremely easy to procure locally, and the dimensions and storage of the product can be easily obtained. Advantages such as the eave height can be set arbitrarily according to the size of the product are provided.
