Description

Description: TECHNICAL FIELD The present invention relates to a method for constructing a dome house using a triangular panel for an air cycle system.

(Prior Art) Conventionally, a dome house, which is a cubic curved surface structure, can obtain a large space, and is therefore widely applied to large buildings such as gymnasiums, pavilions, halls, offices, and general houses.

In particular, geodesic dome houses based on the spherical trigonometry are becoming popular in Japan for general housing, and 2,000 to 5,000 dome houses are built every year in the United States, and hundreds of thousands of residential dome houses have been built so far. Is being built.

On the other hand, in recent years, the use of natural energy has also been actively used in general houses, and for example, passive solar systems that utilize solar heat and natural ventilation by design methods such as structure and floor plan are used. An air cycle system, which is one of the passive solar systems, that is, an air cycle house that makes a gap between an outer wall and a heat insulating material and uses the principle of natural convection of air, has been attracting attention as an energy-saving house.

(Problems to be Solved by the Invention) Although the air cycle system is applied to a conventional house, it is not applied to a dome house where the air cycle system can be most effectively incorporated due to its structure. .

Therefore, according to the present invention, an air cycle is produced by partially pre-manufacturing a triangular panel having a gap between an outer wall and a heat insulating material, assembling the triangular panel, and sequentially bolting them to the outer edge beam of the adjacent triangular panel. The purpose of the present invention is to provide a dome house using the system and its construction method.

(Means for Solving the Problems) In order to achieve the above object, the present invention has the following configuration.

The method for constructing a dome house according to the present invention comprises a lower triangular panel consisting of a flat triangular inner wall plate having a triangular panel, an outer edge beam having a bolt hole formed therein, and a heat insulating material filled therein, an air cycle plate and an outer wall plate. The upper triangular panel is divided and molded, and first, the lower triangular panel is connected by inserting a bolt into a bolt hole, then the upper triangular panel is polymerized and fixed on the lower triangular panel, and finally the upper triangular panel. A waterproof layer is formed on (Example) Hereinafter, the present invention will be described more specifically with reference to Examples.

First, a triangular panel for an air cycle system having a ventilation layer will be described with reference to FIGS. 1 and 2.

The triangular panel 1 for an air cycle system comprises a lower triangular panel 3 and an upper triangular panel 5. The triangular panel 1 is formed in combination with a three-dimensional shape based on the spherical trigonometry, and the outer cover assembled as a whole constitutes a geodesic dome structure. The three angles of the triangular panel 1 are not the same but are calculated in advance. That is, the sum of the three angles is 180 degrees, and the sum of the angles at the center when the triangular panels 1 are butted to form a pentagon or a hexagon is 360 degrees.

The lower triangular panel 3 has bolt holes 8 on the back surface of the inner wall plate 7.
The outer edge beam 9 is fixedly attached. As shown in FIG. 2, the outer edge beam 9 has an upper portion inclined outward by an angle α with respect to the surface of the inner wall plate 7. Therefore, the dome house can be assembled without forming a V-shaped gap with the outer edge beam 9 of the adjacent triangular panel 1 simply by sequentially combining the triangular panels 1.

Further, inside the outer edge beam 9, a reinforcing member 11 is provided in parallel and arranged at right angles to one side of the outer edge beam 9. As shown in FIG. 1, the reinforcing members 11 are symmetrically provided, and the side surfaces thereof are inclined outwardly toward the upper surface similarly to the outer edge beam 9 (see FIG. 2),
Both ends are fixed to the inner surface of the outer edge beam 9, and the bottom surface is fixed to the back surface of the inner wall plate 7.

Further, a heat insulating material such as glass wool or urethane foam is provided in the gap formed by the outer edge beam 9 and the reinforcing material 11.
13 is filled, and a recess 15 is formed on the surface in contact with the bolt hole 8 so that the bolt hole 8 penetrates.

Next, the structure of the upper triangular panel 5 will be described.

The upper triangular panel 5 includes an air cycle plate 17 and an outer wall plate 19.

The air cycle plate 17 is joined to the upper surfaces of the heat insulating material 13 and the outer edge beam 9 and is inserted into the ventilation frame 21 having the cutouts 21a, and the columnar projections 23a are arranged at regular intervals. Ventilation plate made of expanded polystyrene
It consists of 23 and. The depth of the notch 21a of the ventilation frame 21 and the height of the columnar protrusion 23a are substantially the same, the outer wall plate 19 is joined to the upper surface of the columnar protrusion 23a, the ventilation layer 27 between the columnar protrusions 23a.
I am trying. The side surfaces of the air cycle plate 17 and the outer wall plate 19 are inclined at the same angle as the outer edge beam 9.

Since the upper triangular panel 5 is configured as described above, the air cycle plate 17 includes the cutout 21a of the ventilation frame 21 and the ventilation plate 2.
The three protrusions 23a form a ventilation layer 27 that can freely ventilate in three directions.

Although the air cycle plate 17 is formed of the ventilation frame 21 and the ventilation plate 23 in the above embodiment, when the ventilation plate 23 is formed of synthetic wood or the like, it can be integrally formed with the ventilation frame 21 by the same material. Is.

Further, in the above embodiment, the outer edge beam 9 and the air cycle plate are used.
Although the side surfaces of 17 are inclined by the angle α, the invention is not limited to this, and the side surfaces of the outer edge beam 9 and the air cycle plate 17 are formed perpendicularly to the surface of the inner wall plate 7 to form a cubic curved surface structure. The V-shaped gap formed between the outer edge beams 9 when assembled may be filled with a separately formed V-shaped wedge, and the V-shaped wedge may be connected to the outer edge beam 9 integrally by being bolted.

Further, the triangular panel 1 is divided into a lower triangular panel 3 and an upper triangular panel 5 in order to make the surface of the outer wall plate 19 a continuous smooth surface when the dome is formed. First, the lower triangular panel 3 is bolted. After joining, the upper triangular panel 5 is joined. However, by providing the upper triangular panel 5 with a recess extending from the concave portion 15 in advance so that the bolt can be inserted into the bolt hole 8, the lower triangular panel 3 and the upper triangular panel 5 are integrally joined to form a triangular panel. The triangular panel 1 may be assembled.

Next, a construction method for constructing a dome house using the triangular panel 1 will be described.

In the dome house using this air cycle system, the foundation work and the construction method of the first floor are the same as those in the conventional air cycle house, and therefore the dome construction method will be described below.

First, after the foundation A is formed, the lower triangular panels 3 forming the triangular panel 1 are sequentially connected to each other to form the lower triangular panel 3.
Build a dome by. In the lower triangular panel 3, the inner wall plate 7 is directed inward, the side surfaces of the outer edge beam 9 are butted against each other, the bolt 30 is inserted into the bolt hole 8, and the nut 31 is tightened to connect them sequentially. Since the outer edge beam 9 is inclined by the angle α, the dome is formed only by sequentially assembling it.

After forming the dome of the lower triangular panel 3 in this manner, the upper triangular panel 5 is joined onto the lower triangular panel 3. The upper triangular panel 5 is joined on the lower triangular panel 3 with the air cycle plate 17 facing inward and the outer wall plate 19 facing outward, and the screws 33 reaching the outer edge beam 9 are mounted on the peripheral edge of the outer wall plate 19. The upper triangular panel 5 and the lower triangular panel 3 are integrally fixed by driving. It is preferable that the screw 33 is driven in while avoiding the notch 21a in the air cycle plate 17 (see FIG. 3).

In the above embodiment, the triangular panel 1 is divided into the lower triangular panel 3 and the upper triangular panel 5, and the lower triangular panel 3 is first fixed with the bolts 30 and the nuts 31 and then the upper triangular panel 5 is integrally fixed. However, as described above, the triangular panel 1 can be integrally formed with the lower triangular panel 3 and the upper triangular panel 5.
In this case, the recesses 15 are also formed in the air cycle plate 17 and the outer wall plate 19.
The triangular panel 1 itself can be assembled by inserting the bolt 30 through the recess extended from the.

A part of the outer wall plate 19 is cut out at the uppermost part of the triangular panel 1 to form a vent hole 37 communicating with the vent layer 27 of the air cycle plate 17, and a blow-out 39 is provided above the vent hole 37.
And an upper vent 41. On the other hand, a lower vent 43 is provided at the lower end of the triangular panel 1 around the lower edge of the dome, and an insect net 45 is provided over the entire circumference of the ventilation layer 27 of the air cycle plate 17.

Finally, the dome house is completed by providing the waterproof layer 35 on the surface of the outer wall plate 19 forming the dome. Waterproof layer 35
Can be formed by a known method, and for example, can have a known structure such as mortar, enameled iron plate, and tile.

In the case of the above configuration, by opening the upper vent 41 and the lower vent 43, the air can be blown upward from below through the ventilation layer 37 of the air cycle plate 17, and the chimney effect produces a cool wind. Is introduced.

When the upper and lower vents 41 and 43 are closed, an updraft occurs in the air layer warmed by solar heat, and cold air under the floor or on the north side flows to the air layer on the south side and circulates to cool the entire building temperature. Work to keep constant.

Although the lower vent was provided directly at the lower end of the ventilation layer in the above-mentioned embodiment, the air taken in from the lower vent is guided to the underfloor and then allowed to flow to the ventilation layer, or the air is directly introduced to the underfloor and May flow to the ventilation layer.

Further, the entire shape of the dome house is not particularly limited, and it goes without saying that it can be designed in any shape.

(Effects of the Invention) Since the present invention has the above-described configuration, the following effects can be achieved.
