Description

The present invention relates to a prefabricated dome house, and more particularly to a prefabricated dome house provided for sleeping by camping or the like.

Generally, as outdoor accommodation facilities, bungalows made of wood and tents made of cloth have been mainly used. However, since bungalows require the use of separate metal angles and brackets when assembling wood, there is a problem that installation is complicated and takes a lot of time. In addition, since the bungalow is complicated to install in this way, the dismantling is also complicated, and the bungalow is left as it is without being dismantled, so that the space utilization is inferior. The tent has the advantage of being excellent in space utilization because it is easy to install and disassemble, but it has a problem that it is not structurally rigid because its shape is easily deformed by an external force.

As an outdoor accommodation facility that solves such problems, a dome structure consisting of resin panels has been proposed. Such dome structures, which are made of resin panels and are lighter than bungalows, are easier to install and dismantle, and are structurally more robust than tents, so their use has increased recently. It is a trend. Such a dome structure has a form in which the circumferential direction of the dome is equally divided at regular intervals, and a large number of segment panels having an outer peripheral surface having a constant curvature in the vertical and horizontal directions are combined with the segment panels. It consists of a ceiling panel that covers the ceiling part that is exposed when it is done.

However, since the segment panel of the conventional dome structure bends in the vertical direction with a constant curvature, there is a problem that the weight of the ceiling panel, wind pressure, snow cover, and other loads are vulnerable. Along with this, there is a problem that the structural safety of the dome structure is lowered because the segment panel may be damaged or damaged by the load as described above. Further, when the segment panel is divided into a plurality of upper and lower parts for the convenience of construction of the segment panel and assembled, the number of assembly parts that are more vulnerable to the load increases, and the above-mentioned problem further increases. At this time, when a single fuselage segment panel without an assembly part is used to solve the above problem, the vertical length is long and it is not easy to store and transport, and the operator grips it for construction. There is also a problem that is not easy.

The present invention is for solving the above-mentioned problems, and an object of the present invention is to be able to support various loads more firmly, thereby improving structural safety and convenience of installation. However, it is easy to store and transport, and furniture such as shelves can be easily installed in the internal space, reducing the installation space of furniture and increasing the utilization of the internal space, and a separate heat insulating material. The purpose is to provide a prefabricated dome house with excellent heat insulation without the need for construction.

The lower segment panel 20 has a height h1 of 1/2 or more of the above, and the lower end is coupled to the lower segment panel 20 and the upper end is coupled to the ceiling panel 50, but the height h2 is the height of the lower segment panel 20. It is composed of an upper segment panel 40 formed relatively shorter than h1, and at least the back plate 12 of the lower segment panel 20 of the segment panels 10 is provided with reinforcing ribs 60 that are recessed inward and extend vertically. A prefabricated dome house featuring this is provided.

According to another feature of the present invention, at least the side surface portion of the lower segment panel 20 of the segment panel 10 is provided with side joint portions 21 and 25 to be coupled to the side surface portion of the adjacent lower segment panel 10. The side joint portions 21 and 25 are formed by the front plate 11 of the lower segment panel 20 so that the first joint groove 22 and the first joint protrusion 23 extending vertically are sequentially formed along the protrusion direction on the back surface. The first side coupling portion 21 in which a plurality of first bolt holes 24 are vertically separated from each other in the first coupling projection 23; and the back plate 12 of the lower segment panel 20 project laterally to the front surface. The second coupling groove 26 and the second coupling projection 27, which are coupled to the first coupling projection 23 and the first coupling groove 22 of the first side surface coupling portion 21, respectively, extend vertically and back and forth in the second coupling groove 26. The lower segment panel 20 is composed of a second side surface coupling portion 25; in which a plurality of second bolt holes 28 penetrating and aligning with the first bolt hole 24 of the first side surface coupling portion 21 are vertically separated from each other.
