CONSTRUCTION PANEL ASSEMBLY AND CONSTRUCTION METHOD USING SAME

[0001] The present application claims priority under 35 U.S.C. §119(a) to Korean Patent Application No. 10-2014-0116215 filed on Sep. 2, 2014, and Korean Patent Application No. 10-2014-0153727 filed on Nov. 6, 2014, the contents of which are hereby incorporated by reference in their entirety.

[0002] The present disclosure relates to a construction panel assembly which may be assembled and disassembled to partition an indoor space of a building and a construction method using the same, and more particularly, to a construction panel assembly and a construction method using the same, in which a flat panel is mounted on a structure formed in such a way that a main frame and an auxiliary frame are inserted into each other. Thus, materials may be reused, and the generation of waste may be maximally prevented.

[0003] In general, to construct a typical building, a base framework is built through a method in which concrete is formed in a concrete form or steel beams are installed based on design specifications, and then, indoor or outdoor portions such as roofs, ceilings, walls and floors are built and finished.

[0004] Various kinds of buildings are used by partitioning one large indoor space into several small spaces for user convenience without damaging the existing structure of a building, and walls for partitioning the space are classified into fixed walls and assembly walls.

[0005] Fixed walls include masonry walls which need masonry work, plastering work, painting work or wallpapering work to be performed, and wood partitioning walls which need carpentry work, painting or wallpapering work to be performed. Since multiple processes need to be combined to complete a fixed wall, recently, an assembly wall, which is produced as a single panel formed through several processes and assembled, is popular and is being widely used in construction.

[0006] For construction panels, various functional or decorative characteristics such as ease of construction, stiffness and supporting strength, including thermal insulation, fire resistance, waterproofing, and appearance, are required. Recently, various types of construction materials have been widely developed to satisfy these characteristics.

[0007] Until now, since construction panels have also been constructed in a fixed type with respect to non-bearing walls, which are not bearing walls, when a situation arises in which a wall needs to be changed, the reuse of existing materials is almost impossible because the wall is completely removed and then new materials are installed.

[0008] For example, although a steel wall called a steel gypsum panel (SGP) is configured to be assemblable and disassemblable, this steel wall may not be applied to a whole pane of glass wall or a wall including a gypsum panel which is painted or wallpapered. Although this steel wall is separated into a structure material and a finishing material, this steel wall has the disadvantages in that it should be only used for SGP materials and does not sufficiently block noise, etc. because it does not have a shielded structure.

[0009] Moreover, also in construction methods, since finishing materials are coupled to structure materials by using screws, etc., screw heads are exposed. Since an additional packing should be inserted to compensate for this drawback, the consistent connection of walls, such as painting or wallpapering becomes impossible.

[0010] In relation to the installation of construction panels as described above, for example, Korean Patent No. 0695700 discloses a technique which is highly effective for noise blocking and heat insulation, shows noise blocking and fire resisting properties also for studs that form the coupling between panels, has a simple structure allowing for the mutual coupling of parts so as to make assembly convenient, and also allows for assembled firmness. However, since this is nothing but a technique for continuously coupling panels to each other by installing concave-convex portions at both ends with complex structures of the panels themselves, the technique may not be applied to the construction of a whole pane of glass or a whole wall.

[0011] Also, Korean Patent No. 0838961 discloses a technique, in which a modular wall is coupled to a fixing rod by sliding into the fixing rod after the fixing rod is screwed to a ceiling and a floor such that the wall may be simply and quickly installed and removed while minimizing damage to the ceiling and the floor, and thus improve ease of maintenance and repair. However, since the structure of the fixing stud for constructing a wall is complicated, and an elastic body such as a spring or an additional support plate is required to be assembled, a rise in price is caused by the manufacturing of additional materials, and the construction process becomes difficult.

[0012] A typical assembly structure of a construction panel will be described below as an example. As illustrated in the accompanying FIGS. 1 and 2, a steel stud 130 for a non-bearing wall is installed between a floor 110 and a ceiling 120 for constructing a typical drywall 100.

[0013] The steel stud 130 includes upper and lower track members 132 and 134 coupled to the sides of the floor 110 and the ceiling 120 by using an anchor bolt or the like (not shown) and stud members 136 functioning as a plurality of vertical beams assembled between the track members.

[0014] Also, the stud members 136 are fixed by a fixing member 138a horizontally disposed between the stud members 136 and a connection member 138b disposed to continuously extend in a longitudinal direction thereof, and concurrently, are finally are bound by a finishing material such as gypsum board 140, and the stud members 136 and the upper and lower track members 132 and 134 are coupled by screws 142.

[0015] Accordingly, as illustrated in FIG. 2, since the stud members 136 are fastened by the screws 142 from the outside of the track members after the stud members 136 are inserted between the track members 132 and 134 in the case of the typical drywall 100, head portions of the screws 142 protrude more than planes of the track members.

[0016] As a result, in the case of the typical wall 100, there is a limitation in that the process of installing the finishing member 140 after installing the steel stud 130 is interrupted by the head portions of the screws, or a space is generated in the process.

[0017] Furthermore, since the gypsum boards 140 should be finally installed at both sides of the steel stud 130, respectively, the wall becomes thicker, it is cumbersome to perform multiple stages of screw fastening, and it is also undesirable in the aspects of overall material cost or practical use.

[0018] Embodiments provide a construction panel assembly and a construction method using the same, which are applicable to a detachable method capable of assembling and disassembling almost all walls as well as a typical glass wall or gypsum wall, and also allow materials to be reused, so that the generation of construction waste may be minimized.

[0019] Embodiments also provide a construction panel assembly and a construction method using the same, in which structure materials and finishing materials that constitute a wall structure may be firmly fixed to each other even without using separate screws, and the construction thereof is very simple such that overall costs may be greatly reduced.

[0038] The details of one or more embodiments are set forth in the accompanying drawings and the description below. Other features will be apparent from the description and drawings, and from the claims.

[0050] Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0051] Prior to the detailed description of the present disclosure, particular structures or the functional descriptions are only exemplary for the purpose of describing embodiments according to the concepts of present invention, and the embodiments according to the concepts of present invention may be implemented in various forms and shall not be interpreted as limiting the embodiments described in this specification.

[0052] Also, embodiments may have various modifications made thereto and may have many different forms according to the concepts of the present invention. Thus specific embodiments are provided as examples in the drawings and are described in detail in this specification.

[0053] The present disclosure relates to a construction panel assembly which may be assembled and disassembled to partition an indoor space of a building and a construction method using the same. A construction panel assembly according to an embodiment includes a main frame disposed to be arranged to be mutually opposed on a wall surface at a predetermined position determined according to design specifications, an auxiliary frame inserted into the main frame to define a structure, a flat panel 400 mounted on the structure to partition a space, and a finishing member for shielding a connection portion of the main frame and the auxiliary frame.

[0054] Hereinafter, a construction panel assembly and a construction method using the same according to a first embodiment will be firstly described.

[0055] FIG. 3 is an overall perspective view illustrating a construction panel assembly according to a first embodiment, and FIG. 4 is a perspective view illustrating each member of a construction panel assembly according to the first embodiment.

[0056] In the first embodiment, the main frame includes a first main frame 210, the auxiliary frame includes a flat panel fixing member 310 inserted into the first main frame 210, and the finishing member includes a molding 510 and a washboard 610 for shielding the connection portion of the first main frame 210 and the flat panel fixing member 310. The flat panel 400 is mounted between the first main frame 210 and the flat panel fixing member 310 to partition a space.

[0057] As illustrated in the drawings, the present disclosure may be most preferably applied to a wall structure for partitioning a space in a building and include: a first main frame 210 basically fixedly installed between a ceiling and a floor; a flat panel fixing member 310 inserted into the first main frame 210; a flat panel 400 mounted in a flat panel insertion groove 217 defined by the first main frame 210 and the flat panel fixing member 310; and a molding 510 and a washboard 610 for shielding a connection portion of the first main frame 210, the flat panel fixing member 310 and the flat panel 400.

[0058] The first main frame 210 is installed on a ceiling and a floor at a position determined according to design specifications. That is, the main frame 210 may be simply fixed by using a fastening element, such as a small screw (not shown), while the main frame 210 is arranged along reference lines (not shown) marked on the ceiling and the floor.

[0059] Also, the flat panel 400 is inserted while being brought in contact with body support members 211a and 211b, flat panel support members 213a and 213b, and a flat panel guide member 214 of the first main frame 210 fixed to the ceiling and the floor. Then, a support member connecting groove 311 formed in the flat panel fixing member 310 is fastened to a support member connecting protrusion 218 formed at one end portion of the first main frame 210, such that the first main frame 210 and the flat panel fixing member 310 are fixed and the flat panel 400 is simultaneously mounted. Also, the flat panel 400 is inserted into a flat panel insertion groove 217 defined by the first main frame 210 and the flat panel fixing member 310 to define a wall surface. Almost all materials formed into panels, such as wood or gypsum, steel, and glass plates may be used as materials for the flat panel 400.

[0060] A gasket 910 is inserted into a gasket insertion member 511. Then, the molding 510 is inserted into molding insertion grooves 212c and 212d, which are defined by the body support members 211a and 211b, horizontal connection frame support members 212a and 212b, and the flat panel support members 213a and 213b of the first main frame 210, from both sides of the first main frame 210 so as to shield all connection portions in an upper portion of the wall structure. Here, gasket fixing protrusions 219 and 512 and a molding fixing protrusion 912 have an effect of consolidating the coupling of the first main frame 210, the gasket 910, and the molding 510.

[0061] The washboard 610 shields all connection portions in a lower portion of the wall structure in such a way that a washboard upper insertion protrusion 611 is fastened into a washboard insertion groove 216a defined by a washboard insertion protrusion 216 of the first main frame 210, and a washboard lower insertion protrusion 612 is fastened into a washboard insertion groove 215a defined by a washboard insertion protrusion 215 of the first main frame 210. Here, a washboard finishing member 613 contacts a floor surface to have an effect of consolidating the coupling of the washboard 610 and the first main frame 210.

[0062] Also, as illustrated in FIG. 11, when a wall structure in one direction and a wall structure in a direction perpendicular to the one direction are to be connectedly installed, connection frames 800 are interposed on a post frame 700 to mount the flat panels 400 in installation directions of the wall structures.

[0063] That is, concave grooves 701 are formed on the post frame 700 in four directions, such that protrusions 801 formed on the connection frames 800 are fastened to each other. Thus, the assembly of the flat panel 400 is possible in the four horizontal and vertical directions. That is, when the wall structure and the wall structure in a perpendicular direction are to be connectedly installed, they may be freely constructed in the shapes of characters “L”, “T”, and “+” through the same method by using the post frame 700 and the connection frame 800.

[0064] FIG. 5 is a view illustrating an embodiment of the formation of a wall structure in a construction panel assembly according to the first embodiment.

[0065] FIG. 5a is a view illustrating a state in which the upper and lower first main frames 210 are installed, and FIG. 5b is a view illustrating a state in which the post frame 700 is installed.

[0066] FIG. 5c is a view illustrating a state in which the flat panel 400 is installed, FIG. 5d is a view illustrating a state in which the flat panel fixing member 310 is installed, and FIG. 5e is a view illustrating a state in which the molding 510 and the washboard 610 are installed.

[0067] A construction method according to an embodiment may be used to construct not only a wall structure, but also a ceiling or a floor, and may be used for a well ceiling and an image wall through the same method. In other words, when the first main frame 210 is in an up-and-down vertical direction or a left-to-light horizontal direction, or also when the first main frame 210 has a partial installation area, the same construction method may be used with a change only in the position of the first main frame 210.

[0068] Hereinafter, a construction panel assembly and a construction method using the same according to a second embodiment will be firstly described.

[0069] FIG. 6 is an overall perspective view illustrating a construction panel assembly according to a second embodiment, FIG. 7 is a perspective view illustrating a state in which a finishing cover is detached from a construction panel assembly according to the second embodiment, FIG. 8 is a perspective view illustrating a state in which main and intermediate frames are detached from a construction panel assembly according to the second embodiment, FIG. 9 is a cross-sectional view illustrating a state in which a flat panel is assembled in a construction panel assembly according to the second embodiment, FIG. 10 is a view illustrating a state in which each frame and finishing panel of a construction panel assembly according to the second embodiment are disassembled, and FIG. 11 is a view illustrating an embodiment in which a wall structure is installed by using a column post frame.

[0070] In the second embodiment, the main frame includes a second main frame 220, the auxiliary frame includes an intermediate frame 320 inserted into the second main frame 220, the finishing member includes a finishing cover 520 for shielding a connection portion of the second main frame 220 and the intermediate frame 320, and the flat panel 400 is mounted between the intermediate frames 320 to partition a space.

[0071] As illustrated in the drawings, the present disclosure may be most preferably applied to a wall structure for partitioning a space in a building, and includes: second main frames 220 basically fixedly installed between a ceiling wall structure and a floor wall structure; intermediate frames 320 inserted between the second main frames 220, flat panels 400 mounted between the intermediate frames 320, and finishing covers 520 for shielding a connection portion of the second main frames 220 and the intermediate frames 320.

[0072] The second main frames 220 are installed opposite each other on a wall surface at a position determined according to design specifications. That is, the second main frame 220 may be simply fixed by using a fastening element, such as a small screw (not shown), while the second main frame 220 is arranged along reference lines (not shown) marked on the wall surface.

[0073] Also, a mounting groove 221 is formed in a central portion of the second main frame 220, and support members 222a and 222b having openings at both sides of the mounting groove 221 are simultaneously formed. The second main frame 220 includes a plurality of reinforcement protrusions 223 formed integrally on a bottom surface thereof in order to maintain a gap during attachment thereof to a wall surface.

[0074] The intermediate frame 320 includes a central insertion groove 323 which is defined by a protrusion portion 321 inserted into the mounting groove 221 of the second main frame 220, and supporting members 322a and 322b formed at both sides of the protrusion portion 321.

[0075] Also, the flat panel 400 is inserted into the insertion groove 323 of the intermediate frame 320 to form a wall surface. Almost all materials formed in panels, such as wood, gypsum board, steel, and glass plate, may be used as materials for the flat panel 400. When the flat panel 400 is formed of glass, it is preferably formed by interposing molding members 401 at both upper ends and both lower ends thereof.

[0076] The finishing cover 520 is installed by being elastically inserted such that the support members 222a and 222b of the second main frame 220 and the reinforcement members 322a and 322b of the intermediate frame 320 may be simultaneously shielded.

[0077] That is, protrusions 521a and 521b are formed at both upper ends and both lower ends of the finishing cover 520, are coupled to stop recesses 225a and 226b formed at both ends of the bottom surface of the second main frame 220 and reinforcement members 322a and 322b of the intermediate frame 320, and may thus be assembled with or disassembled from each other.

[0078] At upper end portions of the second main frame 220 and the intermediate frame 320, fixing members 920 may be interposed to provide a coupling force. The fixing members 920 are formed in such a way that pairs of vertical bodies 922a and 922b are integrally formed on upper and lower surfaces of a single horizontal body 921, respectively.

[0079] In addition, wire insertion grooves 224 and 324, through which various kinds of wires for indoor wiring may pass, are formed in the reinforcement members 322a and 322b of the intermediate frame 320 and the support members 222a and 222b of the second main frame 220. As a groove 226 is formed between a bottom surface of the second main frame 220 and the finishing cover 520, it may be caulked by using a typical material such as epoxy or polyester.

[0080] Also, as illustrated in FIG. 11, when a wall structure in one direction and a wall structure in a direction perpendicular to the one direction are to be connectedly installed, connection frames 800 are interposed on a post frame 700 to mount the flat panels 400 in installation directions of the wall structures.

[0081] That is, concave grooves 701 are formed on the post frame 700 in four directions, such that protrusions 801 formed on the connection frames 800 are fastened to each other. Thus, the assembly of the flat panel 400 is possible in each of the horizontal and vertical directions.

[0082] To construct a wall structure for partitioning an indoor space according to the above-described configuration, a reference line (not shown) is marked on a ceiling surface and a floor surface based on design specifications, and the second main frame 220 is then arranged and simultaneously fastened and fixed by screws (not shown).

[0083] Here, as a plurality of reinforcement protrusions 223 are integrally formed on a bottom surface of the second main frame 220, a predetermined gap is maintained when the second main frame 220 is coupled to a wall surface, and thus, supporting force may further be reinforced.

[0084] Here, since a plurality of reinforcement protrusions 223 are integrally formed on a bottom surface of the second main frame 220, the second main frame 220 may be more firmly constructed without distortion, and also a predetermined gap is maintained when the second main frame 220 is coupled to a floor surface of a building. Thus, supporting force may further be reinforced and the caulking operation may be more easily performed.

[0085] Next, an insertion groove 323 formed in the intermediate frame 320 is inserted and installed in a coupling portion of a flat panel 400, and both ends of an intermediate frame 320, on which the flat panel 400 is installed, may be installed by being inserted into a mounting groove 221 formed on the second main frame 320.

[0086] Thus, like in a method of assembling a typical window to a window frame, a protrusion portion 321 of the intermediate frame 320, on which the flat panel 400 is mounted, is inserted into the mounting groove 221 formed in the second main frame 220, first from a lower side of the second main frame 220, and then upwardly pushed so as to be vertically installed.

[0087] Also, a fixing member 920 is interposed between the second main frame 220 and the intermediate frame 320, which are disposed at the ceiling wall structure side, such that the second main frame 220 and the intermediate frame 320 may maintain a state of being firmly coupled.

[0088] That is, in a state in which a horizontal body 921 and a vertical body 922a of the fixing member 920 are interposed at the protrusion portion 321 of the intermediate frame 320, the vertical body 922b on the other side is brought in close contact with an inner surface of the insertion groove 221 of the second main frame 220, and may thus be assembled.

[0089] As such, in a state in which the second main frame 220, the intermediate frame 320, and the flat panel 400 are installed, various kinds of wires may be arranged by using wire insertion grooves 224 and 324 formed at both sides of these frames, and a finishing cover 520 is mounted on a connection portion of the second main frame 220 and the intermediate frame 320.

[0090] Here, in a state in which a protrusion 521b formed at a lower end portion of the finishing cover 520 is inserted into stop recesses 225a and 225b of the second main frame 220, a protrusion 521a formed at an upper end portion of the finishing cover 520 is pushed into reinforcement members 322a and 322b of the intermediate frame 320, and thus may be simply assembled.

[0091] Finally, a groove 226 formed between the second main frame and the finishing cover 520 is caulked and finished.

[0092] In the above-described embodiments, a method of installing a wall structure for partitioning a space by using the second main frame 220, the intermediate frame 320, and the flat panel 400 has been described. However, when the wall structure together with a wall structure perpendicular thereto are to be connectedly installed, they may be freely constructed in the shapes of characters such as “L”, “T”, and “+” through the same method by using a post frame 700 and a connection frame 800.

[0093] A construction method according to an embodiment is not limited to only a wall structure and may also be used to construct a ceiling or a floor, and may be used for a well ceiling and a sign image wall through the same method. In other words, when the second main frame 220 is in an up-and-down vertical direction or a left-to-light horizontal direction, or also when the second main frame 220 has a partial installation area, the same construction method may be used with a change only in the position of the second main frame 210.

[0094] According to embodiments, a construction panel assembly and a construction method using the same have the effects in that a panel formed of various materials, such as plate glass, a gypsum board, plywood, and steel, may be constructed to be freely assembled or disassembled by using a main frame and an auxiliary frame which constitute a structure, such that, unlike in the related art, materials may be reused, and accordingly, the generation of waste may be fundamentally prevented.

[0095] Also, since separate screws are not required between structure materials and finishing materials which constitute a wall structure, there are the effects in that the appearance is pleasing and construction is very simple, so that overall costs may be greatly saved.

[0096] Also, many components required to assemble a typical indoor wall structure are simplified, so that processes required for assembly, such as molding and painting, may be reduced and accordingly, manpower and manufacturing costs may be reduced.

[0097] Also, since the assembly and disassembly are simple, there is the effect in that a once-assembled wall structure may be disassembled and may be re-installed at other locations while the height, width, etc, thereof are arbitrarily adjusted and changed by a user.

[0098] Also, since various wires installed indoors may be configured to be disposed between structure materials and finishing materials, various kinds of wires may be freely and conveniently installed if the finishing materials are detached. Also, since wires may be freely disposed without being exposed to the outside even after the construction of the panel is completed, there is the effect in that indoor spaces may be more cleanly used.

[0099] The object of the present invention may be achieved by the aforementioned technical configurations, and although described with limited embodiments and drawings, the present invention is not limited thereto. It should be understood that various modifications and variations can be made by those skilled in the art in the field of present invention without departing from the spirit and scope of the invention. Accordingly, such modifications and variations should also be understood as falling within the claims of the present invention.
