Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a structure for preventing flapping of a membrane in an air tent, which prevents the membrane attached between the wires of the air tent from flapping due to the wind.

(Prior Art) Conventionally, as shown in Fig. 7, when constructing an air tent, the work of attaching the membrane 2 between the wires 1 installed in the vertical and horizontal directions was carried out depending on the scale of the tent. The number of membrane bodies 2 to be installed was several layers of soil, and this work took many days.

In addition, when the membrane body 2 is fully attached, the pressure inside the tent is slightly increased to air up, and the attached membrane body is kept in a taut state. It is being

For this reason, the membrane body 2 that was attached earlier would flap due to the wind and come off from between the wires 1 or be damaged.

Furthermore, the membrane 2 that has come off or is damaged between the wires 1 must be reattached, making the attachment work even more complicated and consuming extra time and effort.

(Problem to be solved by the invention) Therefore, in view of the above-mentioned problems, the inventor of the present invention has developed a method to prevent the membrane from flapping and coming off from between the wires or being damaged by the wind. With the idea of providing a structure, he worked hard and came up with this idea.

(Means for solving the problem) That is, the structure for preventing flapping of the membrane body in the air tent of this invention is characterized in that a bag containing a load is placed on the upper surface of the membrane body attached between the wires. It is something.

(Function) Therefore, the structure for preventing flapping of the membrane body in the air tent of this invention is to arrange a bag which is attached in a relaxed state between the wires and encapsulates the load on the upper surface of the membrane body, so that this bag is in a relaxed state. The attached membrane is pressed to create and maintain a tensioned state of the membrane, that is, a taut state, and prevent the membrane from flapping due to the wind.

In addition, the structure for preventing flapping of the membrane in the air tent of this invention simply places a load-encased bag on the attached membrane to create and maintain the tensioned state of the membrane, thereby preventing the membrane from flapping. This makes construction or removal of the structure extremely easy.

(Embodiments) Hereinafter, preferred embodiments of this invention will be described in detail by way of example with reference to the drawings. However, the dimensions and materials of the components described in this example,
Unless specifically stated otherwise, the shape, relative arrangement, etc. are not intended to limit the scope of this invention, but are merely illustrative examples.

As shown in Figures 1 and 2, the structure for preventing flapping of the membrane in the air tent of this invention is as follows:
It consists of a load 30 and a bag 20 that encloses the load and is placed on the upper surface of a membrane 12 attached between wires 11.

Now, as shown in FIGS. 4 to 6, wires 11 are installed at predetermined intervals in the vertical and horizontal directions of the air tent. The membrane body 12 is attached to.

The membrane body 12 has a predetermined size, for example, 10 m in length and 10 m in width.
The canvas is cut into 10 m long pieces, and a mounting member for attaching the membrane 12 to the wires 11 is provided on the peripheral edge thereof, thereby attaching the membrane 12 between the wires.

That is, as shown in FIG. 3, a plurality of mounting fittings 34 each consisting of a pair of clamping plates 35 and a plurality of bolts 36 are provided on the upper surface of the wire 11 at predetermined intervals in the longitudinal direction of the wire 11. A mounting base 37 is supported on the mounting bracket 34 so as to extend in the longitudinal direction along the wire 11, and a pair of opposing locking portions 38 are formed on the upper surface of the mounting base 37.

Membrane body 1 attached to both ends of the mounting base 37
A bag-shaped portion 39 is formed near the end edge of 2, and a rope 40 is inserted into the inside of the bag-shaped portion 39. Membrane body 1
A fitting part 42 at the proximal end of a locking member 41 is fitted into the bag-shaped part 39 of No. 2, and a mounting base 37 is fitted on the lower surface of the tip.
A claw portion 43 that can be engaged with the upper hook portion 38 is formed. Then, with the claw portion 43 of the hooking member 41 engaged with the hooking portion 38 on the mounting base 37, the hooking member 41 is attached to the mounting base using a nut 44 having a ring-shaped ring 45 protruding from the upper part thereof. 37, the membrane body 12 is attached to both sides of the mounting base 37 in a relaxed state.

Both sides of this mounting base 37, that is, the wire 11
A bag 20 enclosing a load 30 is disposed on the upper surface of the membrane body 12 attached between the two.

As shown in Figure 1, the load 30 is a sand bag, which is a double-layered sandbag measuring 350 mm in length and 900 mm in width, and is filled with sand, and its weight is 20 to 30 kg.
It is. Note that the weight of this load 30 can be changed depending on the type or size of the membrane body.

This load 30 is covered by the bag 20.

As shown in Figures 2 and 4, this back 2
0 is a substantially rectangular polypropylene sheet 22 with eyelets 2 provided at both ends of this sheet 22.
It is hung on the upper surface of the membrane body 12 in a bag-bound state by a hanging rope 24 passing through the membrane body 3 .

That is, the bag 20 is a hanging rope 2 that passes through eyelets 23 provided at both ends of the sheet 22.
4 is wound around the ring-shaped ring 45 and placed on the upper surface of the membrane body 12 in a hanging state.

Furthermore, this bag 20 is provided in a bag-stitched manner by folding a sheet 22 in half and having both ends overlapped and closed by a hanging rope 24, so that the load 30 is covered, that is, does not fall from the bag 20. It is provided.

Next, the action of the flapping prevention structure of the membrane body in the air tent of this invention will be explained.

First, as shown in FIGS. 1 to 6, a double layer is placed on the upper surface of the membrane 12 that is loosely attached between the grits, or wires 11, formed to a predetermined size to match the shape of the air tent. Load 3
0, that is, a bag 20 containing a sand bag is placed.

Next, a ring-shaped ring 45 is installed to protrude from the nut 44 that fixes the hanging member 41 to the mounting base 37.
A hanging rope 24 passing through the eyelet 23 of the bag 20 is wound around the bag 20, and the bag 20 is provided in a suspended state. Therefore, the bag 20 encasing the load 30 presses the membrane 12 that is loosely attached between the wires 11, and maintains the tensioned state of the membrane 12, that is, the state in which the membrane 12 is taut. However, it is possible to prevent the membrane body 12 from flapping due to wind.

Note that the load 30 may be a bag filled with water.

(Effects of the invention) As detailed above, the structure for preventing flapping of the membrane body in the air tent of this invention is that a load-encased bag is placed on the upper surface of the membrane body attached between the wires. The bag placed on the upper surface of the body presses against the membrane attached in a relaxed state, creating and maintaining a tensioned state in the membrane, thereby preventing the membrane from flapping due to the wind.

In addition, this method simply places a load-encased bag on the membrane attached between the wires to create and maintain tension in the membrane and prevent the membrane from flapping. Construction or removal of the structure is extremely simple.
