Description

  The present invention relates to an assembly-type dome in which a plurality of dome pieces of polystyrene foam or reinforced plastic (FRP) are assembled to form a hemispherical living space therein.

  Bungalows using wood are known as conventional outdoor accommodation facilities.

  However, bungalows using wood are expensive to construct and require several days of construction. There are tent-type accommodation facilities, but there is no luxury in terms of durability and appearance, and the installation location is limited.

  An object of the present invention is to provide an assembly-type dome that is made of foamed polystyrene or reinforced plastic, which is particularly suitable as an outdoor accommodation facility.

The assembly-type dome according to the present invention is a collection of a plurality of dome pieces made of foamed polystyrene or reinforced plastic, and a hemispherical living space is formed inside. According to such an assembly-type dome, it is possible to provide an outdoor accommodation facility and a residence that can be constructed in a short period of time and at a low cost.
Further, in the assembly type dome according to the present invention, both edges of the plurality of dome pieces are joined and bonded to each other, and further, the base of the dome piece is locked so as to restrain the movement to the upper part of the plurality of dome pieces. And it is preferable to provide a restraining part in the outer peripheral part of a dome piece so that the movement to the outer peripheral direction of a dome piece may be restrained. Since each base portion of the dome piece is locked to the base, positioning of the dome piece can be facilitated and the dome piece can be prevented from moving upward. Moreover, it can prevent that a dome piece spreads in an external direction by a restraint part.
It is preferable to provide a ventilator at the opening of the top of the dome formed when the plurality of dome pieces are assembled, and engage and fasten the top of each of the plurality of dome pieces to the ventilator.
A dome piece can be formed from a foamed polystyrene having an expansion ratio of 10 to 50 times. Since the magnification is not particularly limited, it may be 1 or 60 times. After assembling the foamed dome pieces into a hemispherical shape, it is preferable to provide a resin concrete layer on the outer surface and the inner surface, and to apply a waterproof paint on the outer surface. A resin primer may be applied to the outer surface and the inner surface, and a weather-resistant and fire-resistant paint may be further applied thereon.
The dome piece can be formed by bonding a reinforced plastic material to both sides of the polystyrene foam. After assembling the dome pieces into a hemispherical shape, spray reinforced plastic on the outer and inner surfaces, spray glass fiber reinforced plastic on the dome pieces, and apply weatherproof and fireproof paint on the surface. Good.
The dome piece can be formed by spraying glass fiber reinforced mortar on both sides of the polystyrene foam. After assembling the dome pieces into a hemispherical shape, a resin primer may be applied to the outer surface and the inner surface, and coating may be applied to the outer surface and the inner surface.
The dome piece can be formed by applying a thick ceramic coating containing glass fibers on both sides of the polystyrene foam. After assembling the dome pieces into a hemispherical shape, a resin primer may be applied to the outer surface and the inner surface, and thick coating may be applied to the outer surface and the inner surface.
Although the strength as a structure can be obtained with only the expanded polystyrene, weather resistance, impact resistance, etc. can be improved by using a thinner expanded polystyrene and covering the surface with a reinforced plastic or the like.
At the top of the dome, the top ends of the plurality of dome pieces may be coupled to each other by a top joint, and both edges of the plurality of dome pieces to be joined to each other may be coupled to each other by an edge joint.
In the above assembly-type dome, a plurality of dome pieces can be assembled, and then the dome can be bound in the circumferential direction by binding means. By constraining the dome piece in the radial direction by a binding means such as a tie band, the dome piece does not come apart even if the dome piece is joined with an adhesive.
After assembling the reinforced plastic (FRP) dome pieces into a hemispherical shape, a layer of a soundproof material or a heat insulating material may be provided on at least one of the outer surface and the inner surface. It may be provided on both sides. Further, it is preferable to provide a layer of a weather-resistant material on the outer surface because durability is improved.

  According to the present invention, it is possible to provide an outdoor accommodation facility and a residence that can be constructed in a short period of time and at a low cost.

  FIG. 1 is an elevation view showing the whole of an assembling type polystyrene dome according to the present invention, FIG. 2 is a plan view, and FIG. 3 is an internal plan view. The assembly-type polystyrene foam dome 100 is a collection of a plurality of dome pieces 10 to 19 made of foam polystyrene, and a hemispherical living space SP is formed inside. In FIG. 1, WD is a window portion provided in advance in a predetermined dome piece, and PT is an entrance provided in advance in the predetermined dome piece.

  Each of the plurality of dome pieces 10 to 19 has a shape as shown in FIG. 4 and is formed from a foamed polystyrene having a foaming ratio of 10 to 50 times and a thickness of 10 to 50 cm. For example, when the maximum amount of snow is about 80 cm, a dome piece made of expanded polystyrene having an expansion ratio of 20 times and a thickness of 20 cm can be obtained. In order to obtain the same strength, the thickness increases as the expansion ratio is increased. Further, in areas where it is not necessary to consider snow accumulation, the expansion ratio can be made larger than 20 times, or the thickness can be reduced to 20 cm or less. On the other hand, in areas where the amount of snow is 1 m or more, the foaming ratio is reduced to 20 times or less to ensure the strength or the thickness is increased. Each of the dome pieces 10 to 19 has an L-shaped base DB, joint edges DE and DD rising from the base DB, and a concave top DR at the tip of the joint edges DE and DD. Such dome pieces 10 to 19 are joined to each other at the top end DR of the dome pieces 10 to 19 by the top joint 22 at the top of the dome, and the joint edges DE and DD of the plurality of dome pieces 10 to 19 are connected to each other. As will be described later, the dome is assembled by being fastened to the adjacent dome piece with the fastener 21 and then bonded.

  FIG. 5 shows a joining edge DE of one dome piece 10 joined to each other, and FIG. 6 shows a joining state of the joining edges DE and DD. FIG. 6 is a cross-sectional view taken along line VI-VI in FIG. 1 showing a joining state of both edge portions DE and DD of the dome pieces 10 to 19. The joint surface is processed as a stepped joint surface so that the joint area becomes a predetermined value or more, and rainwater or the like is prevented from entering the interior living space from the outside of the dome. As can be understood from FIG. 6, the joint edge DE has three slopes DE1, DE2, DE3, and the joint edge DD has three slopes DD1, DD2, DD3. The joint edge DD of the other dome piece 11 joined to the joint edge DE of the dome piece 10 is formed in a shape complementary to the joint edge DE of the dome piece 10. Further, the slopes DE2 and DD2 in the middle part are formed so that the gradient from the rainwater intrusion direction is ascending.

  To assemble the dome pieces, an adhesive is applied to each of the three slopes DE1, DE2, DE3 of the two edge portions DE and the three slopes DD1, DD2, DD3 of the two edge portions DD. When the joint surfaces are joined to each other and a pair of dome pieces are fastened by applying a compressive force from the inside and the outside of the dome with the fastener 21, the joint surfaces are bonded with an adhesive.

  The fastener (edge joint) 21 includes inner and outer pressing plates 211a and 211b and a compression band 212 that compresses these pressing plates 211a and 211b in the joining direction. The compression band 212 is a vinyl bundling band used when bundling the wire harness. Pull out the tip of the compression band 212 from the inside of the dome piece 10 to the outside of the dome piece 11, and reversely pull out the leading end from the outside of the dome piece 11 to the inside of the dome piece 10. One end 212a of the band 212 is pulled to lock to the lock base 212a. Thereby, the joining slopes DE and DD of the dome pieces 10 and 11 receive a compressive force, and a predetermined joining force is obtained together with the adhesive force by the adhesive.

  As described above, the slopes DE2 and DD2 in the middle part are climbing slopes from the rainwater intrusion direction. Therefore, even if rainwater or the like enters from between the joint surfaces DE1 and DD1, the rainwater flows to the dome base side while flowing toward the outside of the dome due to the slopes DE2 and DD2 at the intermediate portion, so the joint surfaces of the slopes DE3 and DD3. Is prevented from entering the living space inside the dome.

  FIG. 7 shows details of the top joint 22. The top joint 22 includes an inner cylinder 221, an outer cylinder 222, a partition wall 223 that partitions the inner cylinder 221 into a cross, a partition wall 224 that partitions a ring-shaped space between the inner cylinder 221 and the outer cylinder 222, The upper collar 225 closes the upper part of the ring-shaped space between the cylinder 221 and the outer cylinder 222, and the lower collar 226 closes the lower part of the ring-shaped space between the inner cylinder 221 and the outer cylinder 222. . The inner cylinder 221 protrudes from the upper lid 225, and the inside is used as an indoor ventilation port. A rain guard 23 is attached to the inner cylinder 221 so that rain or the like does not enter the living space from the outside. In addition, between the upper collar 225 and the lower collar 226, a recess DR formed at the tip of the dome pieces 10-19 is fitted and bonded, and the top of the dome is fastened. As will be described later, the joint 22 is used as an assembly jig when the dome is assembled, and is also used as an indoor ventilator after assembly. It is good also as lighting up the opening part in which the joint 22 is provided.

  FIG. 8 is a diagram showing details of the installation structure of the dome pieces 10 to 19. Dirt concrete PD is placed in the place where the dome is installed. The soil concrete PD supports the dome piece at the same height position as the ground surface GL and the internal dwelling part IM that forms the floor surface FL at a predetermined height (for example, 360 mm) higher than the ground surface GL as shown in the figure. It has a dome support part OM and a dome holding part DS that extends from the dome support part OM to the internal dwelling part IM. The dome holding portion DS is a ring-shaped concave portion. As shown in FIG. 8, the L-shaped base portion DB of each of the dome pieces 10 to 19 is locked to the dome holding portion DS to fix the position of the dome. In addition to ensuring, the dome is restrained from moving upward or in the inner diameter direction. The planar shape of the inner dwelling part IM is a circle, and its outer shape is 7 m. In addition, a restraining mortar SM that prevents the base DB from expanding in the outer diameter direction is provided in a ring shape on the entire outer periphery of the base DB. In FIG. 8, RM is a reinforcing member of concrete PD and mortar SM.

  Next, the assembly procedure will be described with reference to FIG. First, soil concrete PD is placed. Auxiliary support column 31 is erected at the center of soil concrete PD, and top joint 22 is put on the end of support column 31. The base DB of the dome piece 10 is placed on the support portion OM of the soil concrete PD, and the L-shaped base DB is locked to the pressing 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 top recess DR of the dome piece 10 is fitted into the upper and lower collars 225, 226, and the top is positioned.

  Next, the second dome piece 19 is similarly locked and erected on the soil concrete PD. Adhesive is applied to the joint edge DD of the first dome piece 10 and the joint edge DE of the second dome piece 19, and the second dome piece 19 is joined to the dome piece 10. That is, the joint surface DD of the dome piece 10 and the joint surface DE of the dome piece 19 are joined, and both are compressed by the fastener 21 and fastened. As shown in FIG. 1, the fastening by the fastener 21 is performed at predetermined intervals in the vertical direction along the edges DE and DD. On the other hand, the top concave portion DR of the dome piece 19 is also fitted into the upper and lower collars 225 and 226 of the joint 22, and the top portion is positioned. At this time, both are bonded using an adhesive. When such operations are sequentially performed and the edge DD of the dome piece 11 is bonded and bonded to the edge DE of the dome piece 10 as shown in FIG. 9, the assembly of the dome is temporarily finished. Next, the restraining mortar SM is placed outside the base of the dome piece.

  Next, a resin primer is applied to the outer surface and the inner surface of the dome pieces assembled in a hemispherical shape, and after drying, a weather-resistant and fire-proof paint is further applied thereon. Next, interior decoration is performed. As an internal facility, a Western room with a kitchen, bath, and flooring may be provided, or a Japanese-style room with tatami mats may be provided. Although a detailed description of the entrance door and the window is omitted, as shown in FIG. 1, the dome is provided with an entrance part PT and a window part WD.

  Thus, a dome having a hemispherical living space is completed by assembling a plurality of foamed dome pieces by bonding and fastening. Therefore, it is possible to obtain an assembly-type accommodation facility with a low cost and a short construction period. Moreover, the assembly-type dome according to the present invention is an environmentally friendly building because the polystyrene dome piece can be completely recycled.

  The joint edges DD and DE of the dome pieces may be as shown in FIG. In this case, although the rainwater intrusion prevention effect is lower than that of the shape of FIG. 6, the shape is simple, it is easy to join and position both edges DE and DD, and the assemblability is improved. As shown in FIG. 10, instead of the compression band 212, the dome piece can be fastened using a fastener 21 </ b> A including a through bolt 221 and a nut 222.

  As shown in FIG. 11, it is preferable that the tie band TB is wrapped around three locations of the dome 10 in the circumferential direction so that the dome pieces adhered by fastening are not separated. For example, the retaining plate 211a shown in FIG. 6 can be provided with a locking portion, and the tie band TB can be locked to the locking portion. A flexible wire rope or piano wire can be used as the tie band TB. Or various things, such as what couple | bonds the several tie band board each processed in the three-dimensional shape according to the surrounding surface shape of a dome with a screw | thread, and ties a dome in the circumferential direction, can be used. Furthermore, it is possible to prevent the dome from being covered with a net. Therefore, these function as a means for binding the dome pieces.

  In the first embodiment, foamed polystyrene having a foaming ratio of 10 to 50 and a thickness of 10 to 50 cm is used as the dome piece. However, the following dome piece can be used. In addition, the process of an inner and outer surface differs for every polystyrene foam to be used.

(1) The dome piece is formed by using a foamed polystyrene having a foaming ratio of 10 to 50 times and a thickness of 10 to 50 cm as a casing, and 3 to 5 mm of reinforced plastic (FRP) bonded to both sides thereof. In this case, after assembling the dome pieces into a hemispherical shape, a reinforced plastic in which glass fibers are mixed on the outer surface and the inner surface is sprayed and dried. Thereafter, a reinforced plastic mixed with glass fibers is sprayed again, and a weather resistant and fire resistant paint is applied to the surface. Since the FRP functions as a strength member of the dome, the dome piece can be made thinner as compared with the above-described embodiment.

(2) The dome piece is formed by foaming styrene foam having a foaming ratio of 10 to 50 times and a thickness of 10 to 50 cm, and glass fiber reinforced mortar (GRC) is sprayed on both sides with a thickness of 1 to 3 cm. The In this case, after assembling the dome pieces into a hemispherical shape, an acrylic resin primer is applied to the outer surface and the inner surface. Thereafter, the step of spraying and drying glass fiber reinforced mortar with a predetermined thickness is repeated a plurality of times. Finally, paint the outer and inner surfaces. In this example, the GRC is inexpensive, the final coating agent is also inexpensive, and a low-cost dome can be provided.

(3) The dome piece is made of foamed polystyrene having a foaming ratio of 10 to 50 times and having a thickness of 10 to 50 cm as a casing, and ceramic coating containing glass fibers is applied on both sides to improve the strength by several millimeters. is there. After assembling the dome pieces into a hemispherical shape, an acrylic resin primer is applied to the outer and inner surfaces, and thick coating is applied to improve the strength by mixing glass fibers on the outer and inner surfaces. The process of drying this is repeated a plurality of times.

  In the above, as shown in FIG. 8, the L-shaped base portion BD is formed on the dome pieces 10 to 19 and is locked and erected on the soil concrete PD. However, as shown in FIGS. -19 may be fixed to soil concrete PD. In FIG. 12, the anchor bolt AB is embedded in the soil concrete PD in advance, and the dome pieces 10 to 19 are locked to the soil concrete PD with the nut NUT through the washer panel WP. In FIG. 13, the anchor plate AP is previously embedded in the soil concrete PD. Further, the embedded nut NT is embedded in the dome pieces 10 to 19 in advance, and the dome pieces 10 to 19 are locked to the soil concrete PD with bolts BT via the anchor panel AP.

  Further, as shown in FIG. 6, as shown in FIG. 6, unevenness is provided on the joint surface of the dome pieces 10 to 19 and the joint surface is bonded to prevent rainwater from entering, but as shown in FIG. The joining surface 19 may be a flat surface FS, and the joining surface may be filled with a plywood plate VP to prevent rainwater from entering. In this case, a groove for inserting the veneer plate VP into the plane FS is provided in the longitudinal direction. Further, it is preferable to bond the flat surfaces FS to each other, but bonding is not essential if rainwater can be reliably prevented from entering. In the joining structure shown in FIG. 14, the fastener 21 may be omitted. A resin or a metal material may be used instead of the veneer plate.

  In addition, after assembling the foamed dome pieces into a hemispherical shape, resin concrete may be sprayed or applied to the outer surface and the inner surface, and a waterproof paint may be further applied to the outer surface. 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 unevenness, grooves and the like on the surface of the expanded polystyrene to improve the adhesion of the coating material and prevention of peeling.

  The same effect can be obtained when a plurality of dome pieces made of reinforced plastic (FRP) are assembled in place of the foamed dome pieces to form a hemispherical space inside the dome piece. It is done. The structure and assembly procedure when using a 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 resin concrete layer on the inner and outer surfaces. Further, since FRP is inferior in soundproofing and heat insulating properties as compared with foamed polystyrene, it is preferable to spray foamed polystyrene on the inner surface and spray resin concrete onto the surface. If a layer of weathering material is provided on the outermost surface, durability is improved.

  Furthermore, although the hemispherical dome has been described above, 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 other than the dome shape. By using foamed polystyrene or FRP as a constituent material, it is possible to minimize injuries to residents when these houses collapse during an earthquake or typhoon.
