Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to temporary and permanent air membrane structures.

(Prior Art) As conventional air membrane structures, air membrane structures having a single membrane structure, a double membrane structure, and a beam structure are employed.

(Problems to be Solved by the Invention) However, the single-layer membrane structure has problems with the airtightness of entrances and exits and the internal structure of the building because it pressurizes the indoor space.

Further, in a double membrane structure, if the building has the same membrane as another membrane structure, there is a problem that the internal space becomes small.

Furthermore, the beam structure is structurally unsuitable for large-scale structures, and has the problem of being difficult to withstand snow loads and the like.

(Means for Solving the Problems) The present invention relates to an air membrane structure proposed to solve the above problems, in which an arch is disposed between the lower structures, and the arch and the lower structure are connected to each other. A superior membrane and a inferior membrane are installed between the arches and between adjacent arches, and a ventilation hole is provided between the attachment part of the superior membrane and the attachment part of the inferior membrane in each of the arches. The above-mentioned problem is solved by providing an air blower between the upper membrane attachment part and the lower membrane attachment part.

(Function) Since the air membrane structure according to the present invention is configured as described above, the air blowing section of the lower structure is connected to each attachment section of the upper membrane and the lower membrane in the arch disposed in the middle thereof. An air membrane structure is constructed by blowing air between the upper and lower membranes and applying pressure through a ventilation hole provided in the middle. Therefore, there is no need to pressurize the air in the indoor space, there is no need to seal the entrance or the internal structure of the building, and the air membrane structure is reinforced by the arch and sufficiently resists external loads.

(Effects of the Invention) As described above, according to the air membrane structure according to the present invention, there is no need to pressurize the air in the indoor space.
There is no need to make the entrance/exit or internal structure airtight,
In addition, by being reinforced by the arch, it can sufficiently resist wind loads and snow loads, so a large internal space can be secured, and even during deflation, there is sufficient internal space for evacuation. This allows for partial opening and closing of the membrane in the inflated state.

(Example) The present invention will be described below with reference to the illustrated embodiments.

1 and 2 show a first embodiment of the present invention, in which 1 is a lower structure, and an arch 2 is disposed between the lower structures 1. FIG.

An upper membrane 3 and an inferior membrane 4 are disposed between the lower structure 1 and the arch 2 and between the adjacent arches 2 so that their respective attachment parts are vertically separated, and the lower structure 1 and the arch A ventilation section 5 and a ventilation opening 5' in the arch 2 are provided between the attachment parts of both the upper and lower membranes 3 and 4 in the arch 2.

6 in the figure is a blower.

Since the illustrated embodiment is configured as described above, air is blown between the upper and lower membranes 3 and 4 by the blower 6 through the ventilation portions 5 and the ventilation openings 5' in the arch 2, and the air is pressurized to form an air film. Since it constitutes a structure and there is no need to pressurize the air in the indoor space, there is no need to make the entrance/exit and internal structure airtight.

Further, by reinforcing the air membrane structure with the arch 2, it can sufficiently resist wind loads, snow loads, etc., and furthermore, it can take up a large internal space. Sufficient internal space for evacuation can be secured even during deflation.

FIG. 3 shows a second embodiment of the present invention, in which there is a structure that can be opened and closed between adjacent arches 2 at the top of the air membrane structure, and between the arch 2 and the lower structure 1 at the side. An opening 7 is provided.

In the figure, parts equivalent to those of the above embodiment are given the same reference numerals.
