Description

{A constructing structure and constructing method for basics steel frame of air dome}

The present invention relates to the basic construction structure and construction method of an air dome with an air membrane structure. More specifically, when installing an air dome with an air membrane structure, the foundation and frame of the structure are constructed using steel beams and spiral piles, thereby facilitating construction. This relates to the basic construction structure and construction method of an air dome with an air membrane structure to ensure durability against typhoons and convenience of use.

In general, an air dome does not use props to maintain a certain shape of the air membrane (tent), but simply blows air with a blower into the air membrane of the air dome to lift the air membrane by the air pressure inside the air dome, thereby maintaining a constant air membrane. It is a facility that maintains the shape of the structure.

Due to the nature of the air membrane structure, the air-dome is subject to external compression due to atmospheric pressure and wind applied to the air membrane and tension due to internal wind pressure to maintain the dome shape of the air membrane. It is also a structure.

Therefore, the air dome is a structure without supports to support the structure inside, so it has a large internal usable area and is widely used in houses for growing crops that do not require support, exhibition halls, school playgrounds, sports facilities, warehouses, event halls, etc.

In particular, in order to maintain a constant internal temperature of an air dome for a house for growing crops, a double film structure technology such as Patent Application No. 2013-117247 as shown in FIGS. 7 to 9 is disclosed.

That is, the air dome is composed of an inner film 10 and an outer film 20, and entrance and exit spaces 50 are formed on both sides of the air dome, and a machine room is formed at one of the entrances and exits, so that the air pressure of the blower installed in the machine room is formed. This allows the air film of the inner film 10 and the air film of the outer film 20 to maintain the shape of the structure in an expanded state.

At this time, the blower blows external air into the air dome, inside the inner film 10, and into 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. The blower is continuously blown, and when the films are fully expanded and the complete structure shape is maintained, the blower operation is stopped.

Of course, when the air pressure in the air dome drops due to people entering and exiting through the door and the cooling of the air, the blower is started again to restore the structure to an intact state.

If the inner film 10 and the outer film 20 are maintained only by the membrane, they are very vulnerable to strong winds such as typhoons, so a reinforcing net is covered on the surface of the outer film 20, and the reinforcing net is In order to reinforce, the 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 foundation fixing part to maintain the stable condition of the air dome.

In addition, the above-described air dome is constructed by constructing a concrete foundation with drainage channels at all edges of the air dome except for the entrances formed on both sides of the air dome, forming an inner film fixing part and an external film fixing part on the concrete foundation, and then forming a film fixing means. The film is closed so that it can be sealed to prevent the air inside the air dome from easily leaking to the outside.

However, the conventional air dome is a structure in which a steel or concrete foundation is constructed, an inner film fixing part and an outer film fixing part are formed on the foundation, and then the film is finished to be airtight using a film fixing means, so basically, the ground is excavated. Since rebar or concrete must be placed in the excavated area, this requires excavating the ground.

This requires excavating equipment to excavate the ground, and also requires a lot of work time, work volume, and cost to place rebar and pour concrete. In addition, this type of construction method has the disadvantage of frequently occurring cases where construction is impossible depending on the geology of the land.

This is a perspective view of the basic construction structure of an air dome with an air membrane structure according to an embodiment.

First of all, it should be noted that in the drawings, identical components or parts are indicated by the same reference numerals whenever possible. Additionally, in describing the present invention, detailed descriptions of related well-known functions or configurations will be omitted in order to make the gist of the present invention unambiguous.

The basic construction structure of the air dome of the present invention's air membrane structure is as follows.

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

That is, the base of the present invention includes a pair of air dome side support beams 110 connected by a reinforcing bar 113 and arranged to be parallel, and a pair of air dome side support beams 110 located on both ends of the beam located on the outer side of each air dome side support beam 110. It is composed of a pair of extension beams 120 each horizontally coupled to the ground, and a spiral file 160 for fixing the air dome side support beam 110 to the ground, and the frame part of the present invention includes the pair of air domes. Among the side support beams 110, a pair of inner film support beams 130 are each coupled to both ends of the beam located inside each side perpendicular to the ground, and a pair of inner film support beams 130 are connected to both ends of the extension beam 120 perpendicular to the ground. This is achieved by the outer film support beams 140 that are each coupled together.

The steel beam has various structures such as H, I, T, L, and U-shaped, and any structure may be used, but the most preferred steel beam in the present invention is the H beam.

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

The part corresponding to the central horizontal bar of the H beam is called a web, and the vertical bars formed at right angles to the horizontal bar on both sides of the horizontal bar are called flanges. In the present invention, the flange located at the lower part centered on the horizontal bar is called the lower flange 111a, The flange located at the top will be referred to as the upper flange (111b).

The spiral pile 160 has a spiral-shaped spiral locking protrusion 162 formed at the lower part of the cylindrical pile 161, and a locking protrusion 163 is formed at the top, and the spiral locking protrusion 162 is embedded in the ground. To prevent it from falling out easily, the locking protrusion 163 hangs on 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 a typhoon, thereby firmly supporting the air dome of the present invention. make it possible

In addition, in the present invention, in order to support the air dome more firmly, the air dome side support beam 110 can be installed on the concrete water pipe 150, that is, the bench plume, which can act as a weight.

In this case, a significant load is exerted by 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, so that the air dome of the present invention can be stably supported even in fairly strong winds.

At this time, in order to firmly fix the air dome side support beam 110 to the water pipe 150, the air dome side support beam 110 is placed on the side wall 151 of the water pipe 150, and the lower flange 111a of the H beam ) surrounds both sides of the upper end of one side wall 151 of the water pipe 150, and the through hole 111c drilled in the lower flange 111a of the air dome side support beam 110 and the side wall of the water pipe 150 ( 151) The water pipe 150 and the air dome side support beam 110 may be coupled to each other by fasteners, that is, bolts 111d and nuts 111e, through a hole (not shown) drilled on one side of the upper end. .

A bolt coupling hole is formed in the upper flange (111b) of the air dome side support beam 110, and the film fixture 171 is brought into close contact with the film 170 by a compression bolt 172 screwed into the bolt coupling hole. It is preferable that (170) is fixed to the inside of the upper flange (111b) of the H beam.

That is, in the present invention, the film fixing means includes a bolt coupling hole (not shown) drilled on one side of the upper flange (111b) of the air dome side support beam (110). It consists of a bolt coupled to the bolt coupling hole, and a film fixture 171 coupled to one end of the bolt.

A plurality of wire hangers 181 are formed on one side of the upper flange 111b of the air dome side support beam 110 at predetermined intervals, and the wire hangers 181 have wires 180. It is hung to prevent the film 170 and the net (not shown) covering the film 170 from lifting.

In the present invention, the inner film support beam 130 and the outer film support beam 140, which form the frame, are preferably formed in a round shape. This is because in the case of an air dome, it is greatly affected by wind, so a streamlined structure is used to minimize this. Because you have to have it.

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.

In addition, in the case of the extension beam 120, it is structured to support the outer film support beam 140 to form the machine room 201 or the entrance 200 outside the inner film support beam 130. It is also desirable to have a hemispherical or arc-shaped curvature. Of course, it is natural that even if the inner film support beam 130, the outer film support beam 140, and the extension beam 120 are used in a bent structure, they fall within the scope of the present invention.

At this time, it is preferable to form a radius of curvature of the inner film support beam 130 larger than the round diameter of the outer film support beam 140, which means that in the case of the outer film support beam 140, the entrance 200 is formed and the outer film support beam 140 is formed. This is because it is a structure to support the film.

In addition, in the present invention, in a pair of inner film support beams 130, the upper ends of the inner film support beam 130 on one side and the inner film support beam 130 on the other side, which are spaced apart from each other, are connected with a reinforcement wire 190 to form a film. It can also be configured to prevent sagging of (170). This is because if the blowing is stopped due to a power outage or blower failure or when replacing the film 170, the pressure inside the air membrane decreases, causing the film 170 to sag and the crops to be damaged due to its weight. To prevent this, a power outage or blower failure may occur. This structure is necessary to prevent the film 170 from sagging over the crops even if a blower, etc. malfunctions.

The basic construction method of the air membrane structure of the present invention is to space a pair of air dome side support beams 110, which are connected by reinforcement bars 113 and arranged to be parallel, at a predetermined distance at the location where the air dome is to be installed, and place them on the ground surface so that they are parallel to each other. A step of coupling an extending beam 120 horizontal to the ground to both ends of each outer beam among the pair of air dome side support beams 110, and connecting an extension beam 120 to both ends of each inner beam among the pair of beams. Combining the inner film support beam 130 so that it is perpendicular to the ground, coupling the outer film support beam 140 to both ends of the extension beam 120 so that it is perpendicular to the ground, and The step is to ensure that the support beam 110 is fixed by the spiral pile 160 so as not to be lifted by wind, etc.

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

As described above, although the present invention has been described in terms of limited embodiments, the present invention is not limited thereto, and the technical idea of the present invention will be described below by a person skilled in the art to which the present invention pertains.
