Abstract

PURPOSE:To facilitate installation and transfer by installing a tube which serves as outer peripheral anchor for an air bag and into which water can be poured and from which water can be discharged by utilizing the weight of water and attaching the reinforcing cloth in the longitudinal and lateral directions onto the inner and outer surfaces of the air bag. CONSTITUTION:Several pieces reinforcing cloth 2 are placed at the nealry equal intervals in parallel from each side of an anchor and arranged in net form as a whole, and an air bag 1 is formed. Then, said air bag 1 is spread at an installation place, and arranged at a certain position, having a tube 3 on the periphery as outer peripheral anchor. Then, water is poured from a water supply port by using the water supply port of the tube 3 as air feeding nozzle in drain. The internal pressure is increased by supplying air into the inside of the air bag 1, and the internal space is secured by spreading the air bag 1. Therefore, the lightweight and inexpensive reinforcement structure can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention relates to an air membrane structure in which a space is covered with a membrane-like member by utilizing the difference in air pressure between inside and outside.

[Prior art 1] Conventional air membrane structures have a shape that avoids wind pressure in one direction, but a shape that easily receives wind pressure in the direction perpendicular to this, that is, a kamabot shape as shown in Fig. 5, Alternatively, it was spherical and shaped like a balloon, as shown in Figure 6.

[Problem to be Solved by the Invention 1] However, the above-mentioned conventional configuration suffers from insufficient anchoring function due to large wind pressure on windy days, and the need to thicken or reinforce the air film. It had become uneconomical.

The present invention was made in order to solve the above-mentioned conventional problems, and its purpose is to be able to easily install, remove, and move between sites without being subjected to large wind pressure. The object of the present invention is to provide an air membrane structure with sufficient anchorage.

[Means for Solving the Problems 1] The air membrane structure of the present invention can be used as a peripheral anchor of an air membrane.
It is characterized by being equipped with a tube that allows water to be injected and drained using water ff1ffi, and also characterized by having reinforcing cloth attached vertically and horizontally to both the inside and outside of the air membrane. The seven anchors on the outer periphery of the membrane are configured in a rectangular shape, and the reinforcing cloth near each edge #tlX connecting the four corners of the anchor and each end of the air membrane tightening part is arranged in a diamond shape. .

[Embodiment 1] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In Fig. 1, 1 is an air film, and as shown in Figs. 2 and 3, - the air pressure in the inner space of the heavy membrane is increased, and the air pressure pushes up the air film 1 from the inner space. It is designed to ensure internal space.

As is clear from FIG. 3, reinforcing cloths 2 are attached to both the inner and outer surfaces of the air membrane 1. The reinforcing fabric 2 can be attached by attaching it with an appropriate adhesive, by integrally attaching it by heat melting, by sewing both the inner and outer reinforcing fabrics 2, or by a combination of these methods. (1゜Figure 4 shows another example in which the air membrane 1 is made into a double layer model, and the internal air pressure is adjusted to maintain the shape while stretching the membrane. Yes, and in this case as well, there is reinforcing cloth 2 on both the inside and outside.
Attach.

A tube 3 is attached as the outer peripheral anchor of the air membrane 1, and water can be injected or drained into the tube 3. In addition, it is preferable that the water supply port for water injection also serves as an air supply/X-nil during draining, so that the water can be pressurized with air during draining, so that the water can be drained reliably and completely.

As for the method of arranging the reinforcing cloth 2, since the outer circumferential anchors of the air membrane 1 are rectangular, as is clear from the f:tS1 figure, the reinforcing cloths 2 are stretched parallel to each other at approximately equal intervals from each side of the anchors. , are arranged in a mesh pattern as a whole. In this case, the mesh near each ridge line connecting the four corners of the outer circumferential anchor and both ends of the tightening part of the air membrane 1 is configured to have a substantially rhombic shape, so that the membrane rises gradually and has a smooth shape without corners. secure.

Since the air membrane structure of this embodiment is constructed as described above, when using the air membrane 1, first, the air membrane 1 is expanded at the installation location, and the tube 3 around it is placed in a fixed position.

Next, water is injected from the water supply port of the tube 3 to form an anchor.

Next, air v! , 1 to increase the internal pressure and stretch the air membrane 1 to secure the internal space.

[Advantageous Effects of the Invention 1 (1) A tube capable of injecting and draining water using the weight of water is provided as the outer circumferential anchor of the air membrane, making it easy to remove and move, and exhibiting a stable anchor function. Can be done.

(2) Since reinforcing cloth is attached vertically and horizontally to both the inner and outer surfaces of the two-layer membrane, it is possible to create a reinforcing structure that is both small and inexpensive.

(3) The outer circumferential anchor of the air membrane is configured in a rectangular shape, and the reinforcing cloth near each ridgeline connecting the four corners of the anchor and each end of the air membrane frame is arranged in a diamond shape, so that It maintains a smooth shape with gentle edges and no corners, and can effectively withstand wind pressure.
