Description

Air dome foundation construction structure and construction method of air barrier structure

[0001] The present invention relates to a foundation construction structure and a construction method for an air dome having an air membrane structure, and more specifically, to a foundation construction structure and a construction method for an air dome having an air membrane structure, which, when installing an air dome having an air membrane structure, constructs the foundation and frame of the structure using steel beams and spiral piles, thereby ensuring convenience in construction, sturdiness against typhoons, and convenience in use.

[0002] In general, an air dome is a facility that does not use supports to maintain the air barrier (tent) in a certain shape, but simply blows air into the air barrier of the air dome with a blower to float the air barrier by the air pressure inside the air dome, thereby allowing the air barrier to maintain a certain structural shape.

[0003] The above air dome structure is a structure that simultaneously receives external compression force (compression) due to atmospheric pressure and wind applied to the air dome due to the characteristics of a columnless structure, and tensile force (tension) due to internal wind pressure to maintain the air dome shape.

[0004] Therefore, since the air dome is a structure that does not have supports to support the structure from the inside, it has a large internal usable area and is widely used in places that do not require supports, such as greenhouses for growing crops, exhibition halls, school playgrounds, sports facilities, warehouses, and event venues.

[0005] In particular, for greenhouse air domes for crop cultivation, a technology of a double film structure, such as Patent Application No. 2013-117247, as shown in FIGS. 7 to 9, is disclosed to maintain a constant internal temperature.

[0006] That is, the above air dome is composed of an inner film (10) and an outer film (20), and an entrance space (50) is formed on both sides of the air dome, and a machine room is formed in one of the entrances and exits, so that the shape of the structure can be maintained by inflating the air film of the inner film (10) and the air film of the outer film (20) by the air pressure of the blower installed in the machine room.

[0007] At this time, the blower continuously blows outside air into the inside of the air dome, the inside of the inner film (10), and the air layer (S) between the inner film (10) and the outer film (20) so that the air film expands and maintains the shape of the roof, i.e., the structure, and when the films are fully expanded and the complete shape of the structure is maintained, the operation of the blower is stopped.

[0008] Of course, when the air pressure inside the air dome drops due to people coming and going through the door and the air cooling, the blower starts up again to restore the structure to its original shape.

[0009] The inner film (10) and outer film (20) described above are very vulnerable to strong winds such as typhoons when maintained only by a membrane, so a reinforcing net is placed on the surface of the outer film (20), and in order to reinforce the reinforcing net, a wire rope is arranged again on the reinforcing net, and the lower part of the reinforcing net and the lower part of the wire rope are fixed to the base fixing part, thereby maintaining the stability of the air dome.

[0010] In addition, the above air dome is constructed with a concrete foundation having drainage channels on all edges of the air dome except for the entrances formed on both sides of the air dome, and an inner film fixing part and an outer film fixing part are formed on the concrete foundation, and then the film is sealed using a film fixing means to prevent the air inside the air dome from easily leaking to the outside.

[0011] However, the conventional air dome is a structure that constructs a reinforced or concrete foundation, forms an inner film fixing part and an outer film fixing part on the foundation, and then finishes the film so that it can be sealed using a film fixing means. Therefore, it is necessary to excavate the ground and pour reinforcing bars or concrete in the excavated area, which requires construction that involves excavating the ground.

[0012] This method requires excavation equipment to excavate the ground, and placing rebar and pouring concrete requires significant time, labor, and costs. Furthermore, this construction method often presents a drawback: depending on the soil's geology, construction may be impossible.

[0040] First, it should be noted that, among the drawings, identical components or parts are indicated by identical reference numerals, where possible. Furthermore, in describing the present invention, detailed descriptions of related known functions or configurations are omitted to avoid obscuring the gist of the present invention.

[0041] The basic construction structure of the air dome of the air membrane structure of the present invention is as follows.

[0042] First, the present invention uses various steel beams and spiral piles to form an air dome foundation and frame.

[0043] That is, the foundation of the present invention is composed of a pair of air dome side support beams (110) that are arranged to be parallel and connected by a reinforcing bar (113), a pair of extension beams (120) that are respectively connected horizontally to the ground at both ends of beams located on the outer side of the air dome side support beams (110), and a spiral pile (160) for fixing the air dome side support beams (110) to the ground, and the frame of the present invention is composed of a pair of inner film support beams (130) that are respectively connected vertically to the ground at both ends of beams located on the inner side of the pair of air dome side support beams (110), and an outer film support beam (140) that are respectively connected vertically to the ground at both ends of the extension beams (120).

[0044] The above steel beam has various structures such as H, I, T, L, and T-shaped, and any of them may be used, but the most preferred example of the steel beam in the present invention is an H-beam.

[0045] Therefore, it is preferable that the air dome side support beam (110), inner film support beam (130), outer film support beam (140), and extension beam (120) all use H beams.

[0046] In the H-beam, the part corresponding to the central crossbar is called a web, and the vertical bars formed at right angles to the crossbar on both sides are called flanges. In the present invention, the flange located lower than the crossbar is called a lower flange (111a), and the flange located upper is called an upper flange (111b).

[0047] The above spiral pile (160) has a spiral-shaped hooking jaw (162) formed at the bottom of a cylindrical pile (161) and a hooking jaw (163) formed at the top. The spiral hooking jaw (162) is embedded in the ground to prevent it from easily falling out, and the hooking jaw (163) hooks the top of the air dome side support beam (110) to prevent the air dome side support beam (110) from being lifted even in strong winds such as typhoons, thereby allowing the air dome of the present invention to be firmly supported.

[0048] In addition, the present invention can also install an air dome side support beam (110) on a concrete water pipe (150) that can act as a weight to support the air dome more firmly, i.e., on a bench plume.

[0049] In this case, the weight of the water pipe (150) buried in the ground, the weight of the water pipe (150), and the weight of the water filled in the water pipe (150) exert a considerable load, so that the air dome of the present invention can be stably supported even in moderately strong winds.

[0050] At this time, in order to firmly fix the air dome side support beam (110) to the water channel pipe (150), the air dome side support beam (110) is placed on the side wall (151) of the water channel pipe (150), and the lower flange (111a) of the H beam wraps around the upper side of one side wall (151) of the water channel pipe (150) on both sides, and the water channel pipe (150) and the air dome side support beam (110) can be connected to each other by a fastener, i.e., a bolt (111d) and a nut (111e), through a hole (111c) perforated in the lower flange (111a) of the air dome side support beam (110) and a hole (not shown) perforated in one side of the upper side of the side wall (151) of the water channel pipe (150).

[0051] It is preferable that a bolt-joining hole be formed in the upper flange (111b) of the above air dome side support beam (110), and that the film fixing member (171) be pressed against the film (170) by a pressure bolt (172) screwed into the bolt-joining hole so that the film (170) is fixed to the inside of the upper flange (111b) of the H beam.

[0052]

[0053] *That is, in the present invention, the film fixing means is composed of a bolt-joining hole (not shown) perforated on one side of the upper flange (111b) of the air dome side support beam (110), a bolt coupled to the bolt-joining hole, and a film fixing member (171) coupled to one end of the bolt.

[0054] On one side of the upper flange (111b) of the above air dome side support beam (110), a plurality of wire hooks (181) are formed at a predetermined interval, and a wire (180) is hung on the wire hooks (181) to prevent the film (170) and the mesh (not shown) covering the film (170) from being lifted.

[0055] In the present invention, it is preferable that the inner film support beam (130) and the outer film support beam (140) forming the skeleton be formed in a round shape. This is because, in the case of an air dome, it is greatly affected by wind and must have a streamlined structure to minimize this.

[0056] Therefore, it is preferable that the inner film support beam (130) supporting the inner film and the outer film support beam (140) supporting the outer film have a hemispherical or arc-shaped curvature.

[0057] In addition, in the case of the above extension beam (120), it is a structure for supporting the outer film support beam (140) so that a machine room (201) or an entrance (200) can be formed on the outside of the inner film support beam (130), so it is also preferable that it have a hemispherical or arc-shaped curvature. Of course, it is natural that it falls within the scope of the present invention even if the inner film support beam (130), the outer film support beam (140), and the extension beam (120) are used in a folded structure.

[0058] At this time, it is preferable to form the radius of curvature of the inner film support beam (130) larger than the round diameter of the outer film support beam (140), because the outer film support beam (140) is a structure for forming an entrance (200) and supporting the outer film.

[0059] In addition, the present invention can be configured to prevent sagging of the film (170) by connecting the upper ends of one inner film support beam (130) and the other inner film support beam (130) spaced apart from each other in a pair of inner film support beams (130) with a reinforcing wire (190). This is a structure necessary to prevent the film (170) from sagging over the crop even when a power outage, a blower failure, or the like occurs, as the pressure inside the air membrane decreases when the air blowing stops during replacement of the film (170), causing the film (170) to sag and the crops to be damaged due to its weight.

[0060]

[0061] The basic construction method of the air membrane structure of the present invention comprises the steps of: arranging a pair of air dome side support beams (110) that are connected by a reinforcing bar (113) and arranged in parallel to each other on the ground surface at a predetermined interval at a location where the air dome is to be installed; connecting an extension beam (120) horizontally to the ground to both ends of each outer beam among the pair of air dome side support beams (110); connecting an inner film support beam (130) to both ends of each inner beam among the pair of beams so as to be perpendicular to the ground; connecting an outer film support beam (140) to both ends of the extension beam (120) so as to be perpendicular to the ground; and fixing the air dome side support beams (110) by spiral piles (160) so as not to be lifted by wind, etc.

[0062] At this time, welding is preferred for joining steel beams and beams, but joining using bolts and nuts, or rivets, etc. is also acceptable.

[0063]

[0064] As described above, although the present invention has been described by limited embodiments, the present invention is not limited thereto, and various modifications and variations are possible by a person having ordinary skill in the art to which the present invention pertains within the scope of the technical idea of ​​the present invention and the equivalent scope of the patent claims to be described below.
