ASSEMBLABLE PANEL STRUCTURE BACKGROUND OF THE INVENTION

Field of the Invention

[0001] The present invention relates generally to an assemblable panel structure and, more particularly, to an assemblable panel structure having an expansion module

connectable to a core module in an expansive manner.

Description of the Related Art

[0002] A house has long served as the foundation on which mankind can maintain settled

life.

[0003] The types of houses include an apartment, a detached house, a prefabricated

house, and the like.

[0004] Such an apartment or a detached house is mostly a concrete structure.

[0005] Such a concrete structure is robust but is impossible to move once built and has a

limited ability for structural modification.

[0006] For example, in order to expand a completed concrete structure, it is necessary to install the steel frame again and cure the concrete again.

[0007] This causes the construction period to be prolonged.

[0008] The technology that has emerged to shorten the construction period is the

prefabricated house.

[0009] In construction technology, the prefabricated house is constructed using panels

which are pre-manufactured and assembled to complete a house structure.

[0010] However, a prefabricated house in the related art has required separate processing

of the panels to be assembled according to the design.

[0011] Accordingly, extra construction time and cost associated with panel processing may be required.

[0012] Furthermore, much time and effort have been required for the finishing work to maintain the airtightness between the panels to be assembled.

[0013] This is because panel shapes vary depending on the design of the prefabricated house, and the finishing work is required to be separately performed according to the

connection between the panels having various shapes.

[0014] However, the prefabricated house in the related art may have poor heat insulation

performance as compared with a concrete house.

[0015] Furthermore, when the prefabricated house in the related art which has been

completed as designed is required to be expanded, a separate design is required again.

[0016] This is because the prefabricated house in the related art differs from the concrete

structure only in that the construction method is a prefabricated type, and a separate design,

a separate panel processing, and a separate coupling operation are required, which may be

complicated, costly, and time consuming.

[0017] Furthermore, the prefabricated house in the related art may be difficult to move for

installation once completed.

[00133] FIG. 8A, FIG. 8B and FIG. 8C are a view showing coupling variation of the

[00134] Each of the expansion modules M1 to M13 has a rectangular parallelepiped shape,

and the rectangular parallelepiped is configured such that the vertical section thereof has a

regular thickness in four directions and a space is defined therein.

[00135] The expansion modules may all be the same in size and specification.

[00136] The expansion module may be provided at an upper portion thereof with a solar

panel capable of converting the light of the sun into electric energy.

[00137] The expansion module may have an upper roof having an inclination.

[00138] The number of the expansion modules that are connectable is equal to one half of

the number N of the outer side surfaces.

[00139] For example, as shown in FIG. 8A, when the core module 100 is triangular in

horizontal-section (C1), the number of the outer side surfaces is six and three expansion

modules M1, M2, and M3 are connectable to the core module 100.

[00140] Meanwhile, as shown in FIG. 8B, when the core module 100 is rhombic or quadrangular in horizontal-section (a second core module C2), the number of the outer side

surfaces is eight and a total of four expansion modules (the fourth expansion module M4,

the fifth expansion module M5, the sixth expansion module M6, and the seventh expansion

module M7) are connectable to the core module 100.

[00141] As shown in FIG. 8C, when the core module 100 is hexagonal in horizontal

section (C3), the number of the outer side surfaces is twelve and a total of six expansion

modules (the eighth expansion module M8, the ninth expansion module M9, the tenth

expansion module Ml0, the eleventh expansion module Ml1, the twelfth expansion

module M12, and the thirteenth expansion module M13) are connectable to the core

module 100.

[00142] Each of the expansion modules may be configured such that a first end portion

thereof is in surface contact with the outer side surfaces while a second end portion thereof

is coupled to another core module.

[00143] For example, the second expansion module M2 may be coupled to the second core

module C2 at the position of the fifth expansion module M5 coupled to the second core

module instead of the fifth expansion module M5.

[00144] Herein, a first core module Cl is connectable to the second core module C2 in a

state where the first expansion module Ml, the second expansion module M2, and the third expansion module M3 are connected to the first core module, the second core module to which the fourth expansion module M4, the sixth expansion module M6, and the seventh expansion module M7 are connected.

[00145] Alternatively, the second expansion module M2 may be coupled to a third core module C3 at the position of the tenth expansion module M1O coupled to the third core module instead of the tenth expansion module M10.

[00146] Herein, the first core module Cl is connectable to the third core module C3 in a state where the first expansion module Ml, the second expansion module M2, and the third expansion module M3 are connected to the first core module, the third core module to which the eighth expansion module M8, the ninth expansion module M9, the eleventh expansion module M11, the twelfth expansion module M12, and the thirteenth expansion module M13 are connected.

[00147] Meanwhile, it is preferable that an angle between the expansion modules is 720/N.

[00148] In this case, the angle is defined by virtual lines passing through the central axes of adjacent expansion modules of the N expansion modules.

[00149] For example, the first core module Cl has three expansion modules Ml, M2, and M3, and an angle between the central axis of the M1 and the central axis of M2 is a 120 degree angle.

[00150] Meanwhile, the upper core panel 110 according to the preferred embodiment of the present invention may be a combination of six panels having the same shape.

[00151] FIG. 9 is a skeleton of the upper core panel 110 according to the preferred embodiment of the present invention.

[00152] More specifically explained, the upper core panel 110 includes a first coupling member 151, a second coupling member 152, a third coupling member 153, a fourth coupling member 154, a fifth coupling member 155, and a sixth coupling member 156.

[00153] A coupling member 150 may partially constitute the upper core panel 110.

coupling member 153, the fourth coupling member 154, the fifth coupling member 155,

and the sixth coupling member 156 has a first end coupled to the connecting member 157.

[00156] A finishing member 159 is coupled to a second end of each of the first coupling member 151, the second coupling member 152, the third coupling member 153, the fourth

coupling member 154, the fifth coupling member 155, and the sixth coupling member 156.

[00157] The first coupling member 151, the third coupling member 153, and the fifth

coupling member 155 are the same in length and shape.

[00158] The first coupling member 151 and the fourth coupling member 154 are located

on a straight line with each other.

[00159] The second coupling member 152 and the fifth coupling member 155 are located

on a straight line with each other.

[00160] The sixth coupling member 156 and the third coupling member 153 are also

located on a straight line with each other.

[00161] Meanwhile, the second coupling member 152, the fourth coupling member 154,

and the sixth coupling member 156 are the same in length and shape.

[00162] An upper plate (not shown) may be coupled between the first coupling member

151 and the second coupling member 152, between the second coupling member 152 and

the third coupling member 153, between the fourth coupling member 154 and the fifth

coupling member 155, and between the sixth coupling member 156 and the first coupling

member 151, and the overall shape thereof may be the same as in FIG. 1
