FIG. 3 is an explanatory cross-sectional view of the main part of the silo, illustrating the attachment of the lower opening edge at the lower end of the upper storage part 20. The thickness of each component is as follows.
Omitted for simplicity. The upper opening edge 25 of the lower storage container 10 is extended in a flange shape in a horizontal outer direction over the entire circumference. The lower opening edge 40 of the upper storage portion 20 made of a tent canvas is sandwiched between the upper opening edge 25 of the lower storage container 10 and the holding plate 45, and is fixed by a clamp or the like, not shown. This fixation is not limited to the clamp, and it is needless to say that it may be fixed by various fixing means such as bolts and nuts.
In this embodiment, the outer side surface of the upper storage section 20 made of a tent canvas is sewn with a synthetic fiber cloth 46 made of nylon to form a double structure. This cloth 46
May have a double structure so as to cover not only the outer side surface of the upper storage portion 20 but also the entire top portion, that is, cover the entire outer surface of the upper storage portion 20. Further, by making the outer fabric 46 waterproof, the silo can be used outdoors.

FIG. 4 is an explanatory side view showing a state in which the tent frames 15, 15 on the upper part of the silo of the present invention are folded. The tent frames 15, 15 provided on the upper left and right side edges of the upper opening edge 25 of the lower storage container 10 in FIG.
After removing the upper storage portion made of the tent canvas and further removing the tent frames 16, 16, the lower storage container 10 can be folded as shown in the opening side. In this way, when the silo is not used, the upper part of the silo can be folded down and downsized.

Although the embodiment has been described above, in the present invention, the shape and size of the tent can be freely designed, and the structure of the tent frame as a constituent element is completely free. In a flexible tent frame, it is not necessary to divide it into three parts and implement it.
The whole can be formed as one. Pressing plate 4 for fixing lower opening edge 40 of upper storage section 20
5 may be connected to the roots of the tent frames 15, 16 via hinges. Thereby, the holding plate 45 can be arranged at the same time when the tent frame is assembled. The shape of the cylindrical joint is completely free. The tent canvas can also be made of another material. The positions of the entrance and exit of the cement are completely free.

[0014]

The present invention having the above-described structure has the following effects. Conventionally, the entire storage portion of the cement is made of metal. However, in the present invention, since the upper portion is constituted by the tent frame and the sheet, the weight of the entire silo can be extremely reduced. The upper part of the silo is assembled with a tent frame and a sheet, and can be disassembled, and the tent frame can be folded toward the opening side of the lower storage container. In addition, with the reduction in weight and size, the silo itself can be easily moved. Further, in the present invention, since the upper storage portion is formed of a sheet, the amount of cement stored therein is touched from the outside of the sheet with the hand and pressed to determine whether cement remains inside. There is also an advantage that can be confirmed. As described above, the present invention has a remarkable effect.
