Description

[Detailed Description of the Invention] (Field of Application in Business A) This invention is used as an event venue, a gymnasium, a simple warehouse, etc. by expanding the construction material into a tunnel shape, a semi-cylindrical shape, or any other required shape. tent-like structure,
The present invention relates to an installation method that can be constructed in an extremely short time and at low construction cost.

(Prior Art) For example, a conventional method for deploying a tent-like structure in the shape of a tunnel is to use a band-like structure having a length of, for example, 50 to 60 m and 8 degrees, which inflates and contracts by supplying and discharging air. The construction material is first anchored at both lengthwise ends of the construction material in a contracted state, and then the expansion is started by supplying compressed air, often from both ends of the construction material. During this expansion, a 6th layer usually occurs in the center of the construction material.
A common method is to continue expanding the construction material while removing the kinks shown in the figure by lifting it with one or more cranes, ultimately creating a tunnel shape as shown in Figure 7. It was a target.

Note that the depth of such a tent-like structure is determined by arranging building materials similar to those described above in parallel as required,
Inflating them sequentially or simultaneously,
By interconnecting them, they can be increased as appropriate.

(Problems to be Solved by the Invention) However, in such conventional installation methods, the occurrence of kinks in the building materials when air is supplied to them is removed by lifting them with a crane. For example, when setting up a tent-like structure with a width of 45 m and a depth of about 14 m, it takes 36 hours of work from the time the anchors are removed to the end of the installation. At the same time, four crane trucks would be required, resulting in a construction cost of approximately 8 million yen.On the other hand, there was a problem in that there was a lot of space around the construction site to be used only for the traveling and work of the crane trucks. There was a problem in that it was necessary to secure wasted space.

This invention was made by focusing on the problems of the prior art, and it is possible to construct a tent-like structure in an extremely short period of time without using any crane trucks, and without requiring any wasted space. The purpose is to provide a method that can be efficiently installed.

(Means for Solving the Problems) In the deployment method of the present invention, an air pillow is usually arranged in the center of the tent-like structure within the construction site, and on this air pillow, for example, It consists of placing a construction material consisting of a strip-shaped structure similar to that described in the prior art and then lifting at least a portion of the construction material by inflating an air pillow on the basis of the supply of air thereto.

(Function) In this method, for example, after a kink occurs in the belt-like structure during air supply to the belt-like structure as an example of a construction material, the air pillow is inflated to lift the kink part, thereby easily removing the kink. Moreover, it can be quickly removed and the strip structure can be deployed in an extremely short time.

In addition, in this method, the air pillow can be inflated before or simultaneously with the start of air supply to the strip structure, and in such a case, the generation of kinks in the strip structure can be prevented and prevented. can be deployed even more smoothly.

In addition, a roof frame covered with tent material can be used as the construction material, and in this case, the entire construction material is lifted and supported to the required height by air pillows to achieve the desired length. The struts can be easily connected to the construction material.

Therefore, according to this method, there is no need for a crane truck or any space for its travel and work, and it is possible to significantly reduce construction costs and work time.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

First, as shown in Figure 1, an air pillow 1 with a diameter of, for example, about 12 m when inflated is pulled out at a central position in the frontage direction within a construction site for a tent-like structure. Then, the belt-like structure 2 as an example of a structural material is placed on the air pillow.

Here, this band-shaped structure 2 is made of a bag-shaped fabric that has been treated to be airtight, and expands into a beam shape and contracts into a band shape by supplying and discharging compressed air to the hollow portion thereof.

Further, here, both lengthwise ends of the strip structure 2 arranged as described above are fixed to a frame 8, for example, in the ground.
Anchors can be removed by firmly connecting each to 3.

After that, for example, the supply of compressed air from both ends of the band-like structure 2 to the inside thereof is started, and at the same time, the air pipe o -
Start supplying air to 1.

As a result, as the air pillow 1 expands, it lifts the central portion of the band-like structure 2 as shown in FIG. do.

Therefore, after that, by continuing to supply air to the air pillow 1 and the strip structure 2, the strip structure 2, which has been lifted up to a predetermined height by the air pillow 1 in the central portion,
Thereafter, as shown in 3.41A, based on its own internal stress, it separates from the air pillow 1 and expands independently, gradually approaching the tunnel shape. When a predetermined internal pressure, for example, 250 degrees AQ, is supplied to the belt-like structure 2, the belt-like structure 2 assumes the fully-inflated attitude as shown in the seventh sentence.

Here, before the start of air supply to the strip structure 2, the air pillow 1 is inflated to a predetermined diameter to lift the central part of the strip structure 2 to a certain height, thereby preventing the occurrence of a kink in the strip structure 2. It is also possible to prevent
Conversely, after a kink occurs in the strip structure 2, the air pillow 1 can be expanded to remove the kink.

In addition, in the illustrated example, only one air pillow is arranged at the center in the frontage direction, in relation to the length of the strip structure.
It is also possible to arrange a plurality of air pillows at intervals in the frontage direction, and in the illustrated example, the extending direction of the air pillow, which is defined as the depth direction, can also be set as the frontage direction.

FIG. 5 is a perspective view showing another embodiment of the present invention. When the tent-like structure 4 as shown in the figure is expanded, a roof frame 5 covered with tent material is used as the structure material. By inflating the air pillow 1 placed below and lifting the entire roof frame to a predetermined height, and in this state connecting the long columns 6 to the roof frame 5, the column connection work, which was extremely difficult in the past, can be easily done. This makes it possible to do this quickly and easily.

(Effects of the Invention) Therefore, according to the present invention, it is possible to expand a tent-like structure in an extremely short time. For example, a structure similar to that described in the conventional example can be expanded in a working time of about zθ~80 minutes. can be set.

Moreover, here, there is no need to stop the crane at all, so there is no need for space for the crane to travel or work, and the remarkable effect of significantly reducing construction costs is brought about.
