Description

TECHNICAL FIELD

The present invention relates to a dome type structure, and more particularly to a dome type structure, in which main wall parts forming four walls and a portion of a ceiling and corner wall parts forming corners are separately manufactured and are assembled with each other so as to simply and rapidly assemble and disassemble the dome type structure, and the number of the main wall parts is changed and thus the length of the walls of the dome type structure is expanded and contracted so as to change the size of the space within the dome type structure and thus provide various-sized indoor spaces.

BACKGROUND ART

In general, a dome means a hemispheric roof, i.e., an upturned bowl shaped roof. A structure having the above shape refers to a dome type structure, which covers the roof of a circular stadium, such as a baseball ground or a soccer field.
Such a conventional dome type structure was applied to architecture in the Middle Ages, such as Eskimo igloos and African honeycomb housing. As a method for constructing the conventional dome type structure, a ferroconcrete or a polygonal structural frame was used and reconstructed several times. Recently, a solid frame is applied, or a structure, into which air can be injected, is manufactured and air is injected into the structure, thus constructing a dome type structure.
However, in these conventional dome type structures, since the frames forming the general shapes of the structures are mostly fixed, it is impossible to increase the inner area of the dome type structures. Further, if the inner area of the dome type structure is increased, the dome type structure is partially broken down and then reconstructed, or a new dome type structure is separately constructed, thereby requiring a high burden of time and cost and causing a difficulty in construction, and thus being incapable of being easily applied. The dome type structure manufactured by an air injection method is proper to be used for a medium or short time, but has many problems, such as a difficulty in changing the size of the structure and limitations on maintenance of the structure and application of interior and exterior decorative materials for construction.

DISCLOSURE OF INVENTION

Technical Problem

Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a dome type structure, in which main wall parts forming four walls and a portion of a ceiling and corner wall parts forming corners are separately manufactured and are assembled with each other so as to simply and rapidly assemble and disassemble the dome type structure, and the number of the main wall parts is changed and thus the length of the walls of the dome type structure is expanded and contracted so as to change the size of the space in the dome type structure and thus provide various-sized indoor spaces.

Technical Solution

In accordance with an aspect of the present invention, the above and other objects can be accomplished by the provision of a dome type structure comprising main wall parts, forming four walls and a portion of a ceiling, each of which is provided with a lower end fixed to or buried under the ground in each of four directions and an upper end bent in a dome shape toward the center of the upper portion of the structure such that both edges of the upper ends of the neighboring main wall parts contact each other; and corner wall parts disposed at four corners of the structure between the neighboring main wall parts, and thus forming dome type corners.

ADVANTAGEOUS EFFECTS

The dome type structure of the present invention is completed by assembling the main wall parts forming four walls and a portion of a ceiling and the corner wall parts forming corners, which are separately manufactured, thereby being simply and rapidly assembled and disassembled and thus being rapidly constructed as relief facilities or as collective accommodations.
Further, since the number of the main wall parts is changed and thus the length of the walls of the dome type structure is expanded and contracted, the dome type structure can be changed in size of the inner space, thereby being economic and having various constitutions and thus providing several kinds of convenient facilities and accommodations having various indoor spaces.
Moreover, the dome type structure has an excellent structural property of uniform dispersion of load, thereby being capable of reducing the weights of various load support units of a frame.

Further, a window hole 13 is formed through any one of the main wall parts 10, and a window 14, which can be opened and closed, is connected to the window hole 13.
Here, the main wall parts 10 provided with the door 12 and the window 14 are manufactured by a mold using a light-weight material, such as expanded polystyrene, aerated concrete, plaster, silicon, etc., or a heavy-weight material, such as concrete, polymer resin, a solidified material, etc.
In accordance with another embodiment of the present invention, as shown in FIG. 4, a plurality of main wall parts 10 is arranged in the correspondent wall direction, thus forming a rectangular dome type structure. Although not shown, a plurality of the main wall parts 10 may be arranged in each of four wall directions.
The corner wall parts 20, which are respectively disposed at four corners of the dome type structure between the neighboring main wall parts 10, have the shape of a triangular curved board, which is provided with a sharpened upper end and has the shape of one quarter of a hemisphere so as to form dome type corners.
Each of the corner wall parts 20 may be manufactured in one body. However, in the present invention, each of the corner wall parts 20 includes first and second corner wall parts 22 and 24 having the same structure, prepared in a pair, which are divided from each other by a central line.
Here, the saw-toothed engaging protrusion 20 a is formed on each of both side surfaces of the corner wall parts 20 such that the saw-toothed engaging protrusion 20 a can be engaged with the saw-toothed engaging protrusion 10 a of the corresponding one of the main wall parts 10.
In accordance with yet another embodiment of the present invention, as shown in FIG. 5, first and second former wall parts are respectively integrated with neighboring main wall parts, thus forming connection wall parts 50.
The central ceiling part 30 has the shape of a rectangular board, which closes the rectangular hole 5 formed at the ceiling portion by connecting the four main wall parts 10 and contacts the upper surfaces of the main wall parts 10.
More specifically, the central ceiling part 30 includes an outer frame 32, and a transparent window 34 installed in the outer frame 32.
Here, the saw-toothed engaging protrusions (not shown), which are engaged with the saw-toothed engaging protrusions formed on the upper surfaces of the main wall parts 10, may be formed on the outer surface of the outer frame 32.
Further, an outer wall reinforcing material 40 or 42 for reinforcing the outer walls of the main wall parts 10 is provided (with reference to FIGS. 1 and 3).
The outer wall reinforcing material 40 may be ceramic or mortar, which is applied to the outer walls of the main wall parts 10 at a designated thickness, and the thickness of the outer wall reinforcing material 40 is preferably in the range of 0.5˜1.5 mm. Further, the outer wall reinforcing material 42 may be a mesh net having a lattice structure, which is buried in the main wall parts 10.
In the case that a mesh net buried in the main wall parts 10 is used as the outer wall reinforcing material 42, the thickness of the main wall parts 10 is preferably in the range of 1˜10 cm.
The main wall parts 10, the corner wall parts 20, and the central ceiling part 30 may be connected by various connection units (for example, a combination of bolts/nuts) as long as these parts 10, 20 and 30 are easily assembled into the dome type structure or the dome type structure is easily disassembled into the parts 10, 20 and 30.
Further, fastening brackets (not shown) required by the above connection may be properly selected.
Hereinafter, a process for manufacturing the above dome type structure of the present invention will be described.
First, a plurality of the main wall parts 10 forming each of four walls is disposed at a correspondent position.
Here, the lower ends of the main wall parts 10 are fixed to the floor or the ground, or are buried under the floor or the ground so as to more firmly fix the main wall parts 10.
When the disposition of the main wall parts 10 has been completed, as described above, the corner wall parts 20 are disposed at the corner portions between the main wall parts 10, thus completing the outline of the dome type structure provided with the hole 5 formed therethrough.
Here, the main wall parts 10 and the corner wall parts 20 are firstly connected by engagement between the saw-toothed engaging protrusions 10 a formed on both side surfaces of the main wall parts 10 and the saw-toothed engaging protrusions 20 a formed on both side surfaces of the corner wall parts 20 a. Then, under the above state, the main wall parts 10 and the corner wall parts 20 are firmly connected using separate fastening units, such as bolts and nuts.
Thereafter, the central ceiling part 30 is connected to the hole 5, thus completing the dome type structure of the present invention.
In order to protect the outer wall of the dome type structure, the outer wall reinforcing material 40, such as ceramic or mortar, is applied to the outer wall of the dome type structure at a thickness of 1 mm or more, and preferably 0.5˜1.5 mm.
Instead of the outer wall reinforcing material 40 applied to the outer wall of the dome type structure, the outer wall reinforcing material 42 having the structure of a mesh net buried in the main wall parts 10 is used to reinforce the outer wall of the dome type structure.
In order to change the size of the dome type structure, the connection of the main wall parts 10, the corner wall parts 20, and the central ceiling part 30 is released, and then additional main wall parts 10 required to occupy a space of a desired area are further provided and assembled with the existing parts 10, 20, and 30. Thereby, it is possible to construct a new rectangular dome type structure simply and rapidly.
As described above, the respective parts of the dome type structure of the present invention are manufactured in proper places, and are simply assembled at a construction site only using a small number of people and equipment. Thereafter, a finishing process is performed, thus completing the dome type structure.
