Description

My disaster type air green house {Air green house with disaster tolerance}

In the present invention, the overall shape of the air house is formed into a semicylindrical shape, thereby preventing the concentration of stress by keeping the shape of the air film constant and preventing breakage of the air film against external force, It is about the house.

Air house is a structure that forms a certain space inside by injecting wind between an outer film and an inner film. It is widely used as a house for cultivating crops, a simple ceremony facility, and a warehouse.

The conventional air house as shown in FIG. 1 is configured such that the air house is formed into a hemispherical dome shape having a rounded curved roof as a whole, and an entrance and exit facility is directly installed to secure an entrance for user access at one or both ends of the air house (Patent No. 10-1672353).

However, when such a curved air house is fitted with a small straight entry door at one end of the air membrane, a very large local stress is generated at the joint of the air house and the entrance of the air house.

Such stress concentration phenomenon is particularly concentrated at the corners of the entrance facility, so that the film is often damaged at the corners.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is to provide an internal disaster type air cleaner which can prevent stress concentration phenomenon occurring at a joint portion between an air membrane and an entrance facility constituting an air house.

The present invention is intended to provide an internal-disaster air green house capable of preventing the air membrane from being damaged by air pressure or other external force.

According to another preferred embodiment of the present invention, the support frame comprises an upper flange on which an outer film is fixed on an upper surface, a web formed downward from one end of the upper flange, And a lower flange to which the film is fixed.

According to another preferred embodiment of the present invention, a film fastener is fixed to the upper surface of the upper flange and the lower flange, respectively. The film fastener is fixed to the upper surface of the upper flange or the lower flange. And a pressing member which is inserted into the fixed channel through which the film is inserted and the outer side of the fixing channel, and which presses the film inserted into the fixed channel at one end.

According to another preferred embodiment of the present invention, the pressing member is constituted by a bolt member threaded through the outside of the fixing channel and a fixing block pressing and fixing the film to the inside of the fixing channel by the pressing of the bolt member To provide a disaster-resistant air green house.

According to another preferred embodiment of the present invention, the inner film of the air film and the upper surface of the outer film are each provided with a net member, and a ring part is coupled to an outer upper end of the fixed channel, so that the end part of the net member is fixedly coupled to the ring part Wherein the air-permeability of the air-permeable sheet is measured.
