Technical field

The present invention relates to an assembled dome in which a plurality of dome pieces made of styrofoam or reinforced plastic (FRP) are assembled to form a hemispherical living space inside. Background art

Bungalows using wood are known as conventional outdoor accommodation facilities. However, timber-based bungalows are expensive to construct and require several days of construction. There is also a tent-type accommodation facility with a power of ⁵ '. There is no sense of luxury in terms of durability and appearance, and the installation location is limited. Disclosure of the invention

An object of the present invention is to provide an assemblable dome made of styrofoam or reinforced plastic, which is particularly suitable as an outdoor accommodation facility.

The assembly type dome according to the present invention is formed by assembling a plurality of dome pieces each made of styrofoam or reinforced plastic and forming a hemispherical living space inside. According to such a prefabricated dome, it is possible to provide outdoor accommodation facilities and dwellings that can be constructed in a short period of time and at low cost.

Further, in the assembled dome according to the present invention, both edges of the plurality of dome pieces are joined and adhered to each other, and the base of the dome pieces is fixed on the base so as to restrain the upward movement of the plurality of dome pieces. It is preferable to provide a restraining portion on the outer periphery of the dome piece so as to stop the movement of the dome piece in the outer circumferential direction. The structure in which the bases of the dome pieces are locked to the foundation makes it easy to position the dome pieces and also prevents the dome pieces from moving upward. Further, the dome piece can be prevented from expanding in the outer shape direction by the restraining portion.

Ventilation is applied to the opening at the top of the dome formed when multiple dome pieces are assembled. Preferably, the top of each of the plurality of dome pieces is engaged and fastened to the ventilator.

The dome piece can be formed from polystyrene foam having an expansion ratio of 10 to 50 times. Since the magnification is not particularly limited, it may be 1 × or 60 ×. After assembling the dome piece made of foamed polystyrene into a hemispherical shape, it is preferable to provide a resin concrete layer on the outer surface and the inner surface, and further apply a waterproof paint on the outer surface. A resin primer may be applied to the outer and inner surfaces, and a weather-resistant and fire-resistant paint may be applied thereon.

The dome piece can be formed by bonding a reinforced plastic material to both sides of the foamed steel mouth. After assembling the dome piece into a hemispherical shape, reinforced plastic is sprayed on the outer and inner surfaces, glass fiber reinforced plastic is sprayed on it, and weather resistant and fireproof paint is applied on the surface. It may be applied.

The dome piece can be formed by spraying glass fiber reinforced mortar on both sides of the foamed foam mouth. After assembling the dome piece into a hemispherical shape, a resin primer may be applied to the outer surface and the inner surface, and the outer surface and the inner surface may be coated.

The dome piece can be formed by applying a ceramic thick coating containing glass fiber to both sides of the polystyrene foam. After assembling the dome piece into a hemisphere, a resin primer may be applied to the outer surface and the inner surface, and the outer surface and the inner surface may be thickly coated.

The strength as a structure can be obtained with styrofoam alone.ί By using a thinner styrofoam and covering the surface with reinforced plastic, etc., weather resistance, impact resistance, etc. Can be improved.

At the top of the dome, the top ends of the plurality of dome pieces may be connected to each other by a top joint, and both edges of the plurality of dome pieces that are joined to each other may be connected to each other by an edge joint.

In the above-mentioned assembling dome, the dome can be bound by the binding means in the circumferential direction after assembling a plurality of dome pieces. By binding the dome pieces in the radial direction with a binding means such as a tie band, the dome pieces do not come apart even if the dome pieces are bonded with an adhesive. After assembling the reinforced piece of reinforced plastic (FRP) dome into a hemisphere, at least one of the outer surface and the inner surface may be provided with a layer of a soundproofing material or a heat insulating material. It may be provided on both sides. Furthermore, it is preferable to provide a layer of a weather-resistant material on the outer surface because durability is improved.

Embodiment of the Invention

FIG. 1 is an elevational view showing the whole of a prefabricated styrofoam dome according to the present invention, FIG. 2 is a plan view, and FIG. 3 is an internal plan view. Assembled Styrofoam Dome 100 A plurality of dome pieces 10 to 19 made of polystyrene are assembled to form a hemispherical living space SP inside. In FIG. 1, WD is a window provided in advance on a predetermined dome piece, and PT is an entrance provided in advance on a predetermined dome piece.

Each of the plurality of dome pieces 10 to 19 has a shape as shown in Fig. 4, and the expansion ratio is? It is formed of polystyrene foam having a thickness of 10 to 50 cm and a thickness of 10 to 50 cm. For example, when the maximum snow cover is about 80 cm, a dome piece made of foamed styrene having a foaming ratio of 20 times and a thickness of 20 cm can be used. In order to obtain the same strength, the thickness is increased by increasing the expansion ratio. In areas where it is not necessary to consider snow cover, the foaming ratio can be increased to more than 20 times, or the thickness can be reduced to 20 cm or less. Conversely, in areas where the snow cover is 1 m or more, the foaming ratio should be reduced to 20 times or less to secure the strength or increase the thickness. Each of the dome pieces 10 to 19 has an L-shaped base DB, joining edges DE and DD rising from the base DB, and concave tops DR at the tips of the joining edges DE and DD. Such dome pieces 10 to 19 are joined to each other at the top of the dome by connecting the upper end DRs of the dome pieces 10 to 19 with a top joint 22 and a plurality of dome pieces 10 to 19 are joined together. The dome is assembled by fastening each of the joining edges DE and DD of No. 1 to No. 19 to an adjacent dome piece with a fastener 21 as described later.

FIG. 5 shows the joining edge DE of one of the dome pieces 10 to be joined, and FIG. 6 shows the joining state of the joining edges DE and DD. FIG. 6 is a cross-sectional view taken along the line VI-VI of FIG. 1 showing a joining state of both edges DE and DD of the dome pieces 10 to 19. The joint surface is processed as a step-like joint surface so that the joint area is not less than a predetermined value, and at the same time, rainwater and the like from the outside of the dome do not enter the interior living space. As can be understood from FIG. 6, the joining edge D E has three slopes D E 1, D E 2, D E 3, and the joining edge D D has three slopes D D 1, D D 2, D D 3. The joining edge DD of the other dome piece 11 joined to the joining edge DE of the dome piece 10 is formed in a shape complementary to the joining edge DE of the dome piece 10. The slopes D E 2 and D D 2 in the middle part are formed with a rising gradient from the rainwater intrusion direction.

To assemble the dome pieces, three slopes DE1, DE2, Apply adhesive to DE 3 and the three slopes DD 1, DD 2, DD 3 at both edges DD. When the joining surfaces are joined to each other and a pair of dome pieces are fastened by applying a compressive force from inside and outside of the dome by the fastener 21, both joining surfaces are adhered with an adhesive.

The fastener (edge joint) 21 compresses the holding plates 2 1 1 a and 2 1 1 b inside and outside the dome and the holding plates 2 1 1 a and 2 1 1 b in the joining direction. The compression band consists of 2 1 2. The compression band 2 12 is a vinyl binding band used for binding the jahnes. Pull out the tip of the compression band 2 1 2 from the inside of the dome piece 10 to the outside of the dome piece 1 1, and then pull out the end of the compression band 2 1 2 from the outside of the dome piece 1 1 to the inside of the dome piece 10. Then, the joining slopes are bundled, and one end 2 12 a of the compression band 2 12 is pulled to be locked on the lock base 2 12 a. As a result, the joining slopes D E and D D of the dome pieces 10 and 11 are subjected to compressive force, and a predetermined joining force is obtained by bonding with the adhesive force of the adhesive.

As described above, the slopes D E 2 and D D 2 in the middle are the ascending slopes from the rainwater intrusion direction. Therefore, even if rainwater or the like intrudes from between the joint surfaces DE 1 and DD 1, the rainwater flows to the dome base side while flowing to the outside of the dome due to the intermediate slopes DE 2 and DD 2. Intrusion into the living space inside the dome from the interface of DE 3 and DD 3 is prevented.

FIG. 7 shows the details of the top joint 22. The top joint 22 includes an inner cylinder 2 21, an outer cylinder 2 2 2, a partition wall 2 2 3 that partitions the inner cylinder 2 2 1 into a cross, an inner cylinder 2 2 1 and an outer cylinder 2 2 A partition wall 2 2 4 that partitions a ring-shaped space between the inner cylinder 2 and the upper cylinder 2 25 that closes an upper part of the ring-shaped space between the inner cylinder 2 2 1 and the outer cylinder 2 2 2; It comprises a lower collar 222 closing the lower part of the ring-shaped space between the inner cylinder 222 and the outer cylinder 222. The inner cylinder 2 21 projects from the upper lid 2 25, and the inside is used as an indoor ventilation port. A rain cover 23 is attached to the inner cylinder 22 to prevent rain from entering the living space from the outside. In addition, a concave portion DR formed at the tip of the dome pieces 10 to 19 is fitted between and bonded to the upper brim 225 and the lower brim 226, and the top of the dome is fastened. As will be described later, this joint 22 is used not only as an assembling jig when assembling the dome, but also as an indoor ventilation device after assembling. The opening in which the joint 22 is provided may be lighted. FIG. 8 is a diagram showing details of the installation structure of the dome pieces 10 to 19. Soil concrete PD is installed at the place where the dome is installed. As shown in the figure, the dirt concrete PD includes an internal dwelling unit IM that forms a floor FL at a predetermined height (for example, 360 mm) above the ground plane GL, and a ground plane GL. It has a dome support part OM that supports the dome piece at the same height as that of, and a dome holding part DS that extends from the dome support part OM to the internal housing part IM. The dome holding portion DS is a ring-shaped concave portion, and as shown in FIG. 8, the L-shaped base DB of each of the dome pieces 10 to 19 is locked in the dome holding portion DS. In addition, secure the position of the dome and restrain the dome from moving upward or in the radial direction. The internal housing IM has a circular plan shape and an outer shape of 7 m. A mortar SM for restraining the base DB from spreading in the outer diameter direction is provided on the outer periphery of the base DB in a ring shape all around the base DB. In Figure 8, RM is the strengthening member of concrete PD and mortar SM.

Next, the assembly procedure will be described with reference to FIG. Pile of concrete slab concrete is first installed. Auxiliary columns 31 are erected at the center of the soil concrete section PD, and the top joints 22 are placed on the ends of the columns 31. The base portion DB of the dome piece 10 is placed on the support portion OM of the concrete slab concrete PD, and the L-shaped base portion DB is locked to the holding portion DS. Then, the top DR of the first dome piece 10 is locked to the joint 22. That is, as shown in FIG. 7, the recess DR at the tip of the dome piece 10 is fitted into the upper and lower collars 222, 226, and the top is positioned.

Next, the second dome piece 19 is also erected on the concrete slab concrete PD. An adhesive is applied to the joining edge DD of the first dome piece 10 and the joining edge DE of the second dome piece 19, and the second dome piece 19 is joined to the dome piece 10. That is, the joining surface DD of the dome piece 10 and the joining surface DE of the dome piece 19 are joined, and both are compressed and fastened by the fastener 21. Fastening by the fasteners 21 is performed at predetermined intervals in the vertical direction along the edges DE and DD as shown in FIG. On the other hand, the top recess DR of the dome piece 19 is also fitted into the upper and lower flanges 2 25, 2 26 of the joint 22, and the top is positioned. Also at this time, the two are adhered using an adhesive. These operations are sequentially performed. As shown in Fig. 9, the edge DD of the dome piece 11 is joined to the edge DE of the dome piece 10. After bonding, the dome assembly is completed. Next, the restraining mortar SM is cast outside the base of the dome piece.

Next, a resin primer is applied to the outer and inner surfaces of the hemispherically assembled dome piece, and after drying, a weather-resistant and fire-resistant paint is applied thereon. Next, interior decoration is performed. As the internal equipment, a kitchen, bath, flooring Western room, or Japanese-style room with tatami mats may be provided. A detailed description of the entrance door and windows force ^omitted?, As shown in FIG. 1, the entrance portion PT and the window portion WD is provided on the dome. In this way, a dome having a hemispherical living space inside is completed by assembling a plurality of styrofoam dome pieces by bonding and fastening. Therefore, it is possible to obtain low-cost, short-term prefabricated accommodation. Further, the assembled dome according to the present invention is an environment-friendly building because the styrofoam dome pieces can be completely recycled.

The joint edges DD and DE of the dome piece may be as shown in FIG. In this case, the effect of preventing rainwater intrusion is lower than that of the shape shown in FIG. 6, but the shape is simple, it is easy to join and position both edges D E and D D, and the assemblability is improved. As shown in Fig. 10, instead of the compression band 2 12, the dome piece can be fastened using a fastener 21 A made of a through bolt 22 1 and a nut 22 2. .

As shown in FIG. 11, it is preferable that the tie band TB is circumferentially wound around the three points of the dome 10 so that the dome pieces fastened and adhered are not separated. For example, a retaining portion can be provided on the holding plate 21 la shown in FIG. 6, and the tie band TB can be retained on the retaining portion. A flexible wire rope or piano wire can be used as the tie band TB. Alternatively, various things can be used, such as a method in which a plurality of three-dimensional plates each processed into a three-dimensional shape conforming to the peripheral surface shape of the dome are connected with screws to bind the dome in the circumferential direction. In addition, the dome can be covered with a net so that it is not scattered. Therefore, they function as a restraining means for the dome piece.

In the first embodiment, a dome piece having the expansion ratio of 10 to 50 times and a thickness of 10 to 50 cm using styrofoam can be used. The treatment of the inner and outer surfaces is different for each type of styrene foam used.

(1) Dom pieces are foamed foam with a foaming ratio of 10 to 50 times and a thickness of 10 to 50 cm. It is formed by gluing 3 to 5 mm reinforced plastic (FRP) on both sides of the mouth as the body. In this case, after assembling the dome piece into a hemispherical shape, the outer surface and the inner surface are dried by spraying a reinforced plastic containing glass fibers. After that, a reinforced plastic containing glass fiber is sprayed on it again, and a weather-resistant and fire-resistant paint is applied to the surface. Since the FRP functions as a dome strength member, the dome piece can be made thinner as compared with the above-described embodiment.

(2) The dough pieces are made of foam steel with a foaming ratio of 10 to 50 times and a thickness of 10 to 50 cm as a frame, and glass fiber reinforced mortar (GRC) is applied on both sides. ? It is formed by spraying with a thickness of l to 3 cm. In this case, after assembling the dome piece into a hemispherical shape, an acrylic resin primer is applied to its outer surface and inner surface. After that, the process of spraying and drying the glass fiber reinforced mortar to a predetermined thickness is repeated several times. Finally, paint the outer and inner surfaces. In this example, the GRC is inexpensive and the final paint is also inexpensive, providing a low cost dome.

(3) The dome piece is made of foam foam with a foaming ratio of 10 to 50 times and a thickness of 10 to 50 cm as a frame, and ceramic coating containing glass fiber on both sides is used. About several mm to improve the strength. After assembling the dome piece into a hemispherical shape, apply an acrylic resin primer on its outer and inner surfaces, and mix glass fibers on its outer and inner surfaces to improve the strength by thick coating. The process of painting and drying is repeated several times.

In the above, as shown in Fig. 8, the L-shaped base BD was formed on the dome pieces 10 to 19 and was fixed upright on the concrete-filled concrete floor PD, as shown in Figs. 12 and 13. Thus, the dome pieces 10 to 19 may be fixed to the slab concrete PD. In Fig. 12, anchor bolts AB are buried in soil concrete PD in advance, and dome pieces 10-19 are fixed to soil concrete PD with nuts NUT via the washer panel WP c Fig. 13 At this time, the anchor plate AP is buried in the soil concrete PD in advance. Further, the embedding nuts NT are buried in the dome pieces 10 to 19 in advance, and the dome pieces 10 to 19 are locked to the soil concrete PDs by bolts BT via the anchor-panel AP.

In the above, as shown in Fig. 6, irregularities are provided on the joint surface of the dome pieces 10 to 19 As shown in Fig. 14, the joint surfaces of the dome pieces 10 to 19 are flat FS, and the plywood VP is inserted into the joint surface to prevent rainwater from entering. May be prevented from entering. In this case, a groove for inserting the plywood VP in the plane FS is provided in the longitudinal direction. Also, it is preferable that the flat FSs are bonded to each other, but if the rainwater can be reliably prevented from being bonded, the bonding is not essential. In the joining structure shown in FIG. 14, the fastener 21 may be omitted. Resin or metal material may be used instead of the plywood.

After assembling the styrofoam dome piece into a hemispherical shape, a resin concrete may be sprayed or painted on the outer surface and the inner surface, and the outer surface may be further coated with a waterproof paint. Resin concrete may be applied only to the outer surface. Resin concrete is a mixture of resin and concrete and has fire resistance, fire resistance and waterproofness.

It is preferable to provide irregularities, grooves, etc. on the surface of the polystyrene foam to improve the adhesion of the coating material and the prevention of peeling.

In addition, instead of a styrofoam dome piece, a plurality of dome pieces made of reinforced plastic (FRP) are assembled to form a hemispherical space inside, so that an assembling dome can be used. Effects can be obtained. The structure and assembling procedure when using the FRP dome piece are the same as those described above, and a description thereof will be omitted. Also in this case, it is preferable to provide a layer of resin concrete on the inner and outer surfaces. Further, since FRP is inferior in soundproofing and heat insulating properties as compared with polystyrene foam, it is preferable to spray polystyrene foam on the inner surface and then spray resin concrete on the surface. Providing a layer of weather resistant material on the outermost surface improves durability.

Further, in addition to the force dome shape described above with respect to the hemispherical dome, the present invention can be applied to, for example, a rectangular parallelepiped temporary house, a simple house, a villa, a general house, and the like. Ri due to be a constituent member of the polystyrene foam opening Ichiruya FR Ρ, it is possible to minimize the injury of the residents at the time of of these at the time of earthquakes and typhoons houses collapsed _η
