Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal structure which is resistant to a large earthquake, a typhoon, a tsunami and other disasters, has a low building cost, and has a short building period, and a method of building the same.

[0002]

2. Description of the Related Art In recent years, urban development and regional comprehensive development have been promoted in various places. Accordingly, various large buildings such as a gymnasium and a meeting place are required. In addition, as experienced in the Great Hanshin Earthquake, large evacuation shelters and camps are necessary in preparation for large-scale disasters such as earthquakes, fires, tsunamis, river floods, etc.If a disaster actually occurs, It is also necessary to construct emergency shelters and temporary temporary camps on site.

Hitherto, these large buildings are so-called assembling types in which small divided factory products are transported to the site and assembled.

[0004]

However, large-scale prefabricated buildings take time and effort to transport and unload members and parts, and the construction cost increases. In addition, labor and a large amount of connecting parts are required for connecting members and parts, which also causes an increase in cost.

[0005] In addition, the assembled type has a high risk of being damaged at the connecting portion when it is subjected to an earthquake, a typhoon, or the like, and its strength is not sufficient.

Further, it is difficult to construct a building in an emergency in a short period of time, and when the parts or members are not carried in, the construction must be interrupted.

The present invention has been made in view of the above circumstances, and is a low-cost, short-period, and high-strength metal building in which a building can be directly constructed from materials at the building site as a temporary factory. And a method for constructing the same.

[0008]

In order to achieve the above object, according to the present invention, a metal small-diameter tube is spirally formed into a coil, and a metal plate is attached to the surface of the coil. The skeleton is constituted by using the constituted large-diameter tube made of metal as a skeleton.

[0009] The small-diameter pipe made of metal is manufactured from a metal strip by welding. This small diameter tube is easily formed into a spiral coil body. A metal plate can be easily attached to the surface of the coil body by welding. The large-diameter tube thus manufactured can be easily bent into a trabecular column because the core is a coil.

[0010] Therefore, as long as the metal band and its processing device are carried into the building site, the framework is directly assembled from the band at the building site. Then, a wall is attached to the assembled frame to complete the building. If hot water, cold water, or the like is allowed to flow through the coil body composed of the small-diameter pipe in the large-diameter pipe, heating and cooling in the building can be easily performed.

The wall material to be attached to the frame is preferably a metal strip panel. The metal strip panels are simply attached to the framework by welding or the like, and are easily joined together by welding.

The metal strip panel is preferably a surface beam panel having a corrugated plate sandwiched between two flat plates. The face beam panel has a high strength and is easily processed along the skeleton, and is manufactured directly from the metal band material at the building site similarly to the skeleton.

[0013] In other words, when a surface beam panel is used as a metal band-shaped panel, a metal band and a processing device are carried into a construction site, and full operation is performed at the construction site for 24 hours. A large building such as a dome can be built in a short period of time using only metal strips.

When there are many types of members / parts, even if one of them is interrupted, the construction will be interrupted. There is no risk of interruption. Therefore, construction is completed in a short time even in an emergency. Further, costs associated with manufacturing and carrying in parts and components are reduced.

[0015] More preferably, the skeleton is constituted by a monolithic type trabecula which is continuous from the lower part to the upper part of the building. Specifically, for example, the building rises upward from a plurality of outer edges of the building, and is formed in a dome shape by a plurality of vertical bone pillars butted at the center. By using such an integrally molded type trabecula, the number of connection points of the aggregate is further reduced, the construction period is further shortened, and the strength is improved.

The stage can be suspended at the middle position of the room by using the tip of the frame or the pillar. With this stage, the building can be partitioned into multiple floors. Also, high suspension strength is ensured.

Regarding the structure of the wall body, for example, a horizontal strip-shaped panel is stuck in multiple stages in the vertical direction on a vertical portion of a dome-shaped frame, and an inclined portion above the vertical portion is
The vertical strips are attached side by side in the horizontal direction. Alternatively, vertically extending strip-shaped panels that are continuous from the lower part to the upper part are attached to the dome-shaped framework in parallel in the horizontal direction. With this method, it is possible to create a wide range of disaster-prevention-type cities, such as regular large buildings, condominiums, and schools, in addition to the dome type.

In the inclined part of the dome-shaped frame, it is preferable to use a triangular gap formed between the adjacent strip-shaped panels as the inclination as a light window. The triangular panel and the panel for daylighting and ventilation fitted to the light window may be manufactured not at the site but at a factory for manufacturing fixed-size surface beam panels.

FIG. 2 is a plan view and a side view of a joint between a large-diameter pipe and a surface beam panel.

The metal building according to the present embodiment has a structure in which a wall material 200 is attached to the outer surface of a dome-shaped frame 100 as shown in FIGS.

The skeleton 100 is composed of a plurality of vertical bone columns 1.
Are combined in the horizontal direction (circumferential direction). Each trabecular column 110 is an integrally molded product that is continuous from the lower portion to the upper portion, and has a shape in which an inwardly curved arc-shaped portion 110 ″ is continuously provided above a straight portion 110 ′ perpendicular to the ground. The pillars 110, 110 ...
The dome-shaped frame 100 is formed by being erected at a plurality of outer edges of the building and joining each upper end to an annular frame 120 located at the center of the ceiling.

That is, the straight portions 110 'of the plurality of trabeculae 110, 110,... Constitute a vertical portion of the skeleton 100, and the arc-shaped portions 11 of the plurality of trabeculae 110, 110,.
0 ″ constitutes a hemispherical inclined portion of the skeleton 100.

This metal building has a three-layer structure of one basement floor and two floors above ground. The second floor is a hemispherical ceiling room.
As for the flooring material 300 of the ceiling room, the outer peripheral portion has the pillars 110 and 110.
・ Supported by each middle part, and the central part is bone columns 110, 110
..Plural vertical members 310, 31 suspended from each upper end
It is suspended by 0 ... When the floor material 300 is hung, a force in a direction of falling inward is applied to the trabeculae 110, 110,..., But the tips of the trabeculae 110, 110,. Since the falling force is offset, the floor material 300 is suspended and supported with high strength.

The floor material 300 on the second floor and the floor material 400 on the first floor, which also serves as the ceiling of the basement, are formed of a surface beam panel described later together with the wall material 200.

Each of the columns 110 constituting the skeleton 100 includes:
As shown in FIG. 4, a metal plate 11 is formed on the surface of a coil body 112 formed by spirally forming a small-diameter tube 111 made of metal.
3 is formed of a large-diameter pipe 114 which is formed into a cylindrical shape and adhered thereto. The outer metal plate 113 is welded to and integrated with the small-diameter pipe 11 constituting the coil body 112.

Since the large-diameter tube 114 has a composite structure using the coil body 112 as a core, it is lightweight and has high strength. Further, since the core body is the coil body 112, the bending process is easy despite the high strength. As will be described in detail later, the production is simple, and it is possible to produce the building at a construction site of the building from a strip-shaped metal plate as a material.

The wall member 200 includes a floor member panel 210 together with a floor member 300 on the second floor and a floor member 400 on the first floor which also serves as a ceiling of the basement.

As shown in FIG. 5, the face beam panel 210 is a composite metal panel material having a sandwich structure in which a corrugated plate 212 made of metal is sandwiched between two strip-shaped flat plates 211 and 211 made of metal. It is. This face beam panel 21
A value of 0 varies depending on the direction in which the waves of the corrugated sheet 212 are continuous. FIG. 5A shows a transverse wave type in which the direction in which the waves of the corrugated plate 212 are repeated coincides with the width direction of the corrugated sheet, and FIG. 5B shows a longitudinal wave type in which the direction in which the waves are repeated coincides with the longitudinal direction.
There is also a composite face beam panel 210 that combines shear and longitudinal waves for strong structures.

Since this panel material has a corrugated plate 212 as a core material, similar to the large-diameter tube 114 constituting the trabecular column 110,
Light weight and high strength. The characteristics change depending on the direction of the wave of the corrugated sheet 212. The transverse wave type has a particularly high strength in the longitudinal direction, and the longitudinal wave type has a simple bending process in the longitudinal direction.
The composite type combining the shear wave and the longitudinal wave shows high strength in both the longitudinal direction and the plate width direction. As will be described in detail later, the face beam panel 210 is also easy to manufacture, and can be manufactured from a strip-shaped metal plate as a material at the construction site of the building.

In the metal structure according to the present embodiment, the face beam panel 210 is oriented horizontally, as shown in FIG. 1, with respect to the vertical portion except for the hemispherical inclined portion (upper portion) of the frame 100. It is arranged in a vertical direction at a predetermined pitch in multiple stages without gaps, and is wound around this vertical portion in each stage. The face beam panel 210 of each step is fixed to the bone column 110 by welding or the like. Adjacent face beam panels 210 are joined by welding.

On the other hand, as shown in FIG. 2, vertical face beam panels 210 are attached at equal intervals in the horizontal direction (circumferential direction) to the hemispherical inclined portion (upper portion) of the frame 100. . Each face beam panel 210 is formed by the arc-shaped portion 11 of the trabecular column 110.
It is bent along the curve of 0 ". In the hemispherical inclined portion (upper portion) of the skeleton 100, the perimeter decreases as going upward. Therefore, the surface beam is formed so that no gap is formed at the lowermost portion. When the panels 210 are arranged in the horizontal direction (circumferential direction), the face beam panels 210 overlap at the upper part, and the overlapping face beam panels 210 are difficult to clean.

Therefore, in the present embodiment, the horizontal direction (circumferential direction)
The face beam panels 210 are arranged so that the face beam panels 210 do not overlap with each other.
The triangular gap 220 formed between 0 and 210 is positively utilized as a window for lighting. At the same time, the opening formed inside the annular frame 120 is also actively used as a lighting window. A translucent panel is fitted into these windows. A surface beam panel is also preferable as the light-transmitting light-transmitting panel. As this face beam panel, it is preferable that a lath net, not a flat plate, be processed into a corrugated shape and sandwiched between upper and lower flat lath nets and welded, and further a transparent plate adhered.

The bone column 110 composed of the large-diameter tube 114 has a circular outer shape. For this reason, the face beam panel 210 is
It is difficult to fix directly. Therefore, as for the face beam panel 210 constituting the wall material 200, as shown in FIG. 6A, a square frame-shaped connecting member 130 is attached to the trabecular column 110, and the face beam panel 210 is welded or screwed thereto. I do. The rectangular frame-shaped connecting member 130 is united and joined by bolts or welding as a half-split type.

The face beam panel 210 is a floor material 300 on the second floor.
And the floor member 400 on the first floor, which also serves as the ceiling of the basement, but as shown in FIG. 6 (b), the face beam panel 210 constituting the floor material has a square frame-like connection having a receiving portion. The member 140 is attached to the trabecular column 110,
1, the face beam panel 210 is welded or screwed. This square frame-shaped connecting member 140 is also combined as a half-split type by bolting or welding.

The face beam panel 210 is lightweight, has high strength, and is easy to bend in a specific direction, so that it can be easily applied to the wall material 200. Furthermore, the manufacture of the skeletal columns 110 constituting the skeleton 100 is simple, and both can be manufactured at the construction site of the building.

Next, the trabecular column 110 constituting the skeleton 100

The narrow strip-shaped metal plate 111 'is made into a small-diameter pipe 111 by a continuous manufacturing method similar to a conventional welded pipe. That is, the band-shaped metal plate 111 ′ is gradually formed into a U-shaped cross section,
Furthermore, it is formed into a circular cross section and the butted edges are welded to each other. The manufactured small-diameter pipe 111 is processed into a coil shape by a forming roll (not shown) to form a coil body 112. The manufactured coil body 112 advances in the axial direction outside the columnar core body 510 having excellent electrical conductivity such as copper.

The wide band-shaped metal plate 113 'is shown in FIG.
As shown in the figure, the coil body 112 is gradually formed into a U-shaped cross section, and further formed into a circular cross section.

As shown in (b), four welding electrodes 521, 522,
523 and 524 are provided. The welding electrode 521 is provided above the core body 510, and the coil body 11 is provided at the most upstream side.
2 from above. The welding electrode 523 is provided below the core body 510 and faces the coil body 112 from below on the most downstream side. The welding electrodes 522 and 524 are provided on both sides of the core body 510, and the coil body 1 is disposed between the welding electrodes 521 and 523.
12 from both sides.

That is, the four welding electrodes 521, 522,
523 and 524 are displaced in both the circumferential direction and the axial direction in accordance with the torsion of the coil body 112.

As described above, the wide band-shaped metal plate 11
3 'is gradually formed into a U-shaped cross section so as to cover the coil body 112, and further formed into a circular cross section. In the process of forming, first, the center in the width direction of the strip-shaped metal plate 113' is located on the upstream side. Is pressed against the coil body 112 by the welding electrode 521 and positioned. In this state, the forming of the band-shaped metal plate 113 ′ proceeds, and when the forming into a U-shaped cross section is completed, the band-shaped metal plate 113 ′ is pressed against the coil body 112 from both sides by the welding electrodes 522 and 524. In this state, the core 510
A predetermined voltage is applied to the welding electrodes 522 and 524 with the ground as ground, and the strip-shaped metal plate 113 ′ is

The coil body 112 and the strip-shaped metal plate 113 'are synchronously advanced in the axial direction. By repeating the above-described resistance welding for each pitch of the coil body 112, the cylindrical metal plate 113 covering the coil body 112 is welded to the coil body 112 at four locations on the upper and lower sides for each pitch.

Thus, the large-diameter tube 114 is continuously and directly manufactured from the narrow band-shaped metal plate 111 'and the wide band-shaped metal plate 113'. The welding location in the circumferential direction and the welding pitch in the axial direction are appropriately selected.

The manufactured large-diameter pipe 114 is connected to a bending device 600.
, And cut into a bone column 110. The bending apparatus 600 includes a carriage 610 provided with bending rolls 611, 611,.... The truck 610 is carried into the construction site by a truck or a trailer, and the pipe making device 50
0 is set downstream.

When a disaster such as the Great Hanshin Earthquake occurred,
The pipe making device 500 and the bending device 600 are carried into a vacant land such as a ground, and the belt-shaped metal plate 11 as a raw material is put together.
If the coils of 1 'and 113' are carried in, the trabeculae 11
0 is produced. If the full operation is performed for 24 hours, a large amount of the trabecular bone 110 is manufactured in a short period of time. If the manufactured trabecular columns 110 are sequentially assembled with a heavy machine, the skeleton 100 is completed in a short time.

As shown in FIG. 10, a face beam panel 210 to be attached as a wall material 200 to the frame 100 is also provided.

12 "is drawn out, processed into a corrugated sheet 212, and
If sandwich welding is carried out between 1 and 211, the surface beam panel 210 will be manufactured continuously.

As for the production of the face beam panel 210, if the manufacturing apparatus and the coil are carried into the construction site, a large number of face beam panels 210 can be manufactured in a short time by full operation for 24 hours.
If the face beam panel 210 to be manufactured is cut to an appropriate length and attached to the skeleton 100, the building is completed in a short time.

The face beam panel 210 attached to the skeleton 100 is not only fixed to the skeleton 100 but also
The edges of the adjacent face beam panels 210 are welded to each other. By this edge welding, airtightness in the building is ensured and the strength of the wall material 200 is ensured. Face beam panel 2
The edges on both sides of 10 are not rigid and are not always suitable for welding.

To solve this problem, as shown in FIG. 11A, both sides of the flat plates 211 and 211 are extended to both sides of the corrugated plate 212, and a core 213 having a U-shaped cross section is provided between the extended portions. Fit welding with the open side inside (or outside). This welding is performed by pressing the web portion of the core 213 from the outside with a metal pad 240 such as copper, and energizing the projecting portions of the flat plates 211 and 211 together with the core 213 with the welding electrodes 230 and 230 interposed therebetween. Face beam panel 210
Is a transverse wave type, as shown in FIG. 11B, a core 213 conforming to a space shape formed between both side edges of the flat plates 211 and 211 is fitted into this space and welded.
It is preferable to use the backing 240 for this welding. In either case, the edges on both sides of the face beam panel 210 are reinforced, making them suitable for welding.

This reinforcement is also performed by the face beam panel 21 shown in FIG.
0 can be performed continuously in the process of continuous production.

FIGS. 12 and 13 are longitudinal sectional views of a metal building according to another embodiment of the present invention.

In the metal building shown in FIG. 12, a dome-shaped frame 100 is formed by forming a trabecular column 110 into a spiral shape. Such a framework 100 is also manufactured at a construction site by the above-described continuous method. In addition, since the trabecular column 110 is continuous from the lower part to the upper part, the number of joints is small, and it is durable and easy to construct. A plurality of the trabeculae 110 may be used to increase the rising angle.

Surface beam panel 210 constituting wall material 200
Are vertically oriented, are arranged in the horizontal direction (circumferential direction) without gaps, and are fixed to the skeleton 100. The upper part of each face beam panel 210 is curved corresponding to a hemispherical upper shape.

In the metal building shown in FIG. 13, a kamaboko-shaped frame 100 is formed by combining a plurality of trapezoidal columns 110, 110. Wall material 200
Are all vertically oriented. The rooftop is formed flat so that it can be used as a rooftop.

These structures are also produced economically in a short time from coils at the construction site.

The features of the metal structure according to the present invention are listed below.

There are few types of members and parts. Therefore, the number of joints is small and the strength is high. Although many buildings were destroyed in the previous Great Hanshin Earthquake, much of the damage occurred at junctions. The metal structures according to the invention with few joints are of very high strength and can withstand strong earthquakes. Although there is a danger of lava flow and the like near a volcano, the metal building according to the present invention can withstand this. Of course, the strength of the trabecular column 110 and the wall material 210 is high.

A small number of members and parts means a reduction in transportation costs, which contributes to a reduction in construction costs. In the metal building according to the present invention, since the construction period is short, the construction cost is very low.

When a disaster occurs, it can be built immediately on site. When a disaster occurs, the transportation network is cut off and it is impossible to order many types of parts and parts. The metal building according to the present invention can be built on-site as long as the manufacturing apparatus, the coil, and some heavy equipment are carried into the site. In the Great Hanshin Earthquake, it took several months even to build simple temporary housing. In the case of the metal structure according to the present invention, it does not take one month to build a large-scale structure of the dome type baseball field class.
24 hours of full operation will further shorten this period.
A relatively small one can be completed in a few days. It is suitable as a temporary shelter in the event of a disaster. For small buildings,
It is also possible to build a strong basket-shaped structure by omitting the trabecular column and connecting only the face beam panels.

Since the strength of the building is high, there is no problem even if there is a large aftershock. Displaced people can spend their days with peace of mind. In addition, this building is soundproof, heat-resistant and heat-insulating and resistant to fire. The panels themselves can be thought of as fire walls, cool in summer and warm in winter. If the panels are connected in an airtight manner, toxic gas countermeasures will be thorough. If the foundation is strong, it will not be washed away by the tsunami. Furthermore, it can be used not only for buildings, but also for large-sized containers such as refrigerated and heat-insulated transport vehicles and ships, and has high versatility.

The large-diameter tube 114 used for the trabecular column 110
It has a coil body 112 composed of a small-diameter tube 111. If hot or cold water is allowed to pass through this small-diameter pipe 111,
The inside of the building is easily and comfortably temperature controlled without special piping.

[0066]

As described above, according to the metal building and the building method according to the present invention, a metal small-diameter tube is formed into a coil shape by forming it into a spiral shape, and a metal plate is formed on the surface of the coil body. By constructing the skeleton using a large-diameter metal pipe formed by sticking as a skeleton, a building can be directly constructed from materials at the construction site as a temporary factory. Therefore, the construction cost and the construction period can be significantly reduced. In addition, since the trabecular column is strong and has few joints, high strength and safety can be secured. Further, the present invention is not limited to the dome shape, and can be applied to various buildings having an arbitrary design such as a normal square, polygon, kamaboko, east roof, and the like.

When a face beam panel is used as a wall material to be attached to a frame, the wall material can be directly built from a material at a construction site, and high strength can be secured. Therefore, economy and strength can be further improved.
