[0001] The present application claims priority to Korean Patent Application No. 10-2025-0009994, filed Jan. 23, 2025, the entire contents of which are incorporated herein for all purposes by this reference.BACKGROUNDTechnical Field

[0002] The present disclosure relates to a building exterior panel supporting apparatus and an exterior panel construction method using the building exterior panel supporting apparatus. More particularly, the present disclosure relates to a building exterior panel supporting apparatus and an exterior panel construction method using the building exterior panel supporting apparatus configured such that an insulation material does not need to be separately cut and the exterior panel supporting apparatus mounted on an outer wall by bolt fastening is capable of being constructed rapidly within a short time, thereby improving constructability.Description of the Related Art

[0003] Generally, an outer wall refers to an outer wall surface of a building exposed to the outside. In the past, the outer wall was mainly finished by painting or by decoration using bricks or the like. However, in recent years, methods of fixing exterior panels formed of a metal material such as aluminum to an outer side of a wall surface of a building to enhance an external appearance have been widely used.

[0004] The methods of fixing exterior panels to a completed wall surface of a building are largely classified into a wet method and a dry method. The wet method is a method in which an exterior panel is disposed in surface contact on an outer side of a wall surface and cement or the like is poured between the wall surface and the exterior panel to fix the exterior panel. In the wet method, a construction period including curing is long, and workability and constructability are poor, so that the wet method is rarely used at present.

[0005] In contrast, the dry method is a method in which an exterior panel is coupled to an outer wall by using a separate fastening member formed of metal or the like. Compared to the wet method, the dry method has excellent constructability and workability, so that the dry method is currently used mainly.

[0006] As illustrated in FIG. 1A and FIG. 1B, a building exterior panel supporting apparatus 1 in the dry method includes a first frame 2 fixed to and mounted on an outer wall 10 by an angle 3 in a state in which an insulation material 20 is attached to the outer wall 10, and includes a second frame 4 welded and fixed in a horizontal direction to upper and lower portions of the first frame 2.

[0007] Here, since the first frame 2 and the second frame 4 are welded and fixed to each other, the number of work processes increases, so that there is a problem that construction costs are increased.

[0008] Accordingly, the present applicant filed Korean Patent Application Publication No. 10-2024-0020907 on Feb. 14, 2024. Korean Patent Application Publication No. 10-2024-0020907 relates to a building exterior panel supporting apparatus and an exterior panel construction method using the building exterior panel supporting apparatus. As illustrated in FIG. 2 to FIG. 3E, a building exterior panel supporting apparatus 50 includes a bracket 100 mounted on an outer wall 10 of a building at a predetermined distance by bolt fastening, a horizontal frame 200 mounted in a horizontal direction on the bracket 100 by bolt fastening so as to be spaced apart from the outer wall 10 by a predetermined distance, and a vertical frame 300 mounted in a vertical direction on the horizontal frame 200 by bolt fastening. In addition, the exterior panel construction method using the building exterior panel supporting apparatus includes: a first process in which the bracket 100 is mounted on the outer wall 10, a second process in which the horizontal frame 200 is mounted on the bracket 100, a third process in which an insulation material 20 is mounted between the horizontal frames 200, a fourth process in which the vertical frame 300 is coupled to the horizontal frame 200 such that a lattice shape is formed, and a fifth process in which an exterior panel 30 is mounted on the horizontal frame 200 and the vertical frame 300.

[0009] However, in an actual construction site to which Korean Patent Application Publication No. 10-2024-0020907 is applied, in the process of mounting the insulation material 20 between the horizontal frames 200, the insulation material 20 is required to be separately cut to match a distance between the horizontal frames 200. This acts as an inconvenience in the construction process, so that there has been a demand for a further improved device and construction method.

[0010] Accordingly, the present applicant proposes an improved building exterior panel supporting apparatus and an exterior panel construction method using the improved building exterior panel supporting apparatus.DOCUMENT OF RELATED ART(Patent Document 1) Korean Patent No. 10-1580642 (registered on Dec. 21, 2015)

[0035] Hereinafter, an exemplary embodiment of a building external panel supporting apparatus and an external panel construction method using the building external panel supporting apparatus will be described in detail with reference to the accompanying drawings.

[0037] The present disclosure relates to a building exterior panel supporting apparatus 50 capable of increasing constructability since an exterior panel supporting apparatus mounted on an outer wall by bolt fastening is capable of being rapidly constructed within a short time. As illustrated in FIG. 4 to FIG. 8B, the building exterior panel supporting apparatus 50 may include an anchor bolt 110 fixed to and mounted on an outer wall 10 through an insulation material 20 disposed on the outer wall 10, a bracket 100 screw-coupled to the anchor bolt 110, a first frame 200 mounted on the bracket 100 in a horizontal direction or a vertical direction by bolt fastening, and a second frame 300 mounted on the first frame 200 in the vertical direction or the horizontal direction by bolt fastening.

[0038] More specifically, a plurality of anchor bolts 110 may be mounted on predetermined positions such that the anchor bolts 110 pass through the insulation material 20 and are fixed to the outer wall 10 in a state in which the insulation material 20 is in close contact with and disposed on the outer wall 10 of a building.

[0039] In addition, each anchor bolt 110 may have a corresponding bracket 100 mounted thereon.

[0040] The bracket 100 may include a plate-shaped body 101 having a predetermined area, a penetration hole 103 may be formed in a center portion of the body 101, and a threaded portion 102 which has a thread formed on an inner circumferential surface of the threaded portion 102 such that the threaded portion 102 is capable of being screw-coupled to the anchor bolt 110 and which is in communication with the penetration hole 103 may be provided.

[0041] Accordingly, in a state in which a thread of the anchor bolt 110 and the threaded portion 102 of the bracket 100 are engaged with each other so that the anchor bolt 110 and the bracket 100 are coupled to each other, when the bracket 100 is rotated in a forward direction or a reverse direction, the bracket 100 is moved in a longitudinal direction of the anchor bolt 110 along the thread, so that a distance by which the bracket 100 is spaced apart from the insulation material 20 is capable of being adjusted.

[0042] Here, it is preferable that a position of the bracket 100 is adjusted such that a rear surface of the bracket 100 is in close contact with a front surface of the insulation material 20.

[0043] Meanwhile, in the first frame 200, first and second flanges 220 and 230 may be formed by bending both end portions of a first body 210 in up and down directions outwardly, the first body 210 having a “U”-shaped cross-section.

[0044] Accordingly, the first and second flanges 220 and 230 of the first frame 200 are brought into close contact with an outer surface of the body 101 of the bracket 100 and are fixed to and mounted on the outer surface of the body 101 of the bracket 100 by bolt fastening.

[0045] Here, when a mounting position of the bracket 100 does not correspond to a mounting position of the first frame 200, an auxiliary bracket 400 may be additionally mounted between the bracket 100 and the first frame 200.

[0046] The auxiliary bracket 400 may be formed in a plate shape having a predetermined area, and may be mounted on the body 101 of the bracket 100 by bolt fastening such that the auxiliary bracket 400 extends toward the first frame 200, so that the first flange 220 and the second flange 230 of the first frame 200 may be brought into close contact with the auxiliary bracket 400 and may fixed to and mounted on the auxiliary bracket 400 by bolt fastening.

[0047] In addition, the first flange 220 and the second flange 230 serve to allow coupling with the second frame 300 to be described later.

[0048] The second frame 300 includes a second body 310 having a “U”-shaped cross-section, and both end portions of the second body 310 in left and right directions may be bent outwardly so that a third flange 320 and a fourth flange 330 are formed.

[0049] Accordingly, as illustrated in FIG. 8A and FIG. 8B, the third flange 320 and the fourth flange 330 of the second frame 300 are brought into close contact with outer sides of the first flange 220 and the second flange 230 of the first frame 200 and are fixed to and mounted on the outer sides by bolt fastening. In addition, upper and lower ends of the second body 310 of the second frame 300 are in close contact with and supported by bent lower and upper ends of the first body 210 of the first frame 200, respectively.

[0050] With the configuration described above, the first frame 200 and the second frame 300 may be easily and firmly coupled to each other only by bolt fastening, without requiring separate fixing means or welding operations.

[0051] In addition, since the first and second flanges 220 and 230 of the first frame 200 and the third and fourth flanges 320 and 330 of the second frame 300 are formed by bending rather than extrusion, there are effects that manufacturing costs are reduced and manufacturability is increased.

[0052] Meanwhile, it is preferable that the first frame 200 and the second frame 300 are mounted such that the first body 210 and the second body 310 form a lattice shape.

[0053] Accordingly, an exterior panel 30 is mounted such that the exterior panel 30 covers the first body 210 of the first frame 200 and the second body 310 of the second frame 300, the first body 210 and the second body 310 being mounted in the lattice shape.

[0054] In the present disclosure, it is illustrated and described that the first frame 200 is mounted in the horizontal direction and the second frame 300 is mounted in the vertical direction. However, although not illustrated, the first frame 200 may be mounted in the vertical direction and the second frame 300 may be mounted in the horizontal direction.

[0055] Finally, a construction sequence of the present disclosure will be described with reference to FIG. 9 and FIG. 10A to FIG. 10F.

[0056] First, a first process S1 in which the insulation material 20 is disposed on the outer wall 10 of the building is performed.

[0057] Next, in a state in which the insulation material 20 is in close contact with the outer wall 10 in the first process S1, a second process S2 in which the anchor bolt 110 is mounted on the outer wall 10 through the insulation material 20 such that the anchor bolt 110 is fixed to the outer wall 10 is performed.

[0058] Here, the plurality of anchor bolts 110 may be installed at predetermined positions such that threaded portions of the anchor bolts 110 having threads formed on outer circumferential surfaces of the anchor bolts 110 protrude forward from the insulation material 20.

[0059] In addition, in the second process S2, it is preferable that the anchor bolts 110 are mounted at predetermined distances on the same line in the left and right directions and the up and down directions. However, the anchor bolts 110 may be freely mounted so as to improve work efficiency at an actual construction site.

[0060] Next, a third process S3 in which the bracket 100 is mounted on the threaded portion of the anchor bolt 110 is performed.

[0061] Here, it is preferable that a position of the bracket 100 that is screw-coupled to the anchor bolt 110 is adjusted according to a thickness of the insulation material 20 so that the bracket 100 is in close contact with the front surface of the insulation material 20.

[0062] Next, a fourth process S4 in which the first frame 200 is mounted on the bracket 100 is performed.

[0063] Here, the first frame 200 is installed so as to be seated on the brackets 100 installed at predetermined distances on the same line in the left and right directions on the outer wall 10 in the first process S1. In this manner, a plurality of first frames 200 are mounted in multiple rows on the brackets 100 arranged in the up and down directions.

[0064] Here, when the brackets 100 are not mounted at predetermined distances, the first frame 200 may be installed by connecting the auxiliary bracket 120 therebetween.

[0065] Next, a fifth process S5 in which the second frame 300 is coupled to the first frame 200 such that a lattice shape is formed is performed.

[0066] Here, a front surface of the first body 210 of the first frame 200 and a front surface of the second body 310 of the second frame 300 are mounted such that the front surfaces are positioned on the same plane.

[0067] In addition, since the first frame 200 and the second frame 300 are mounted such that the first frame 200 and the second frame 300 cover a portion of the front surface of the insulation material 20, the first frame 200 and the second frame 300 also serve to prevent separation of the insulation material 20.

[0068] Next, a sixth process S6 in which the exterior panel 30 is mounted on the first frame 200 and the second frame 300 is performed. Here, the exterior panel 30 may be mounted on the front surface of the first body 210 of the first frame 200 and the front surface of the second body 310 of the second frame 300 mounted in the lattice shape by a known coupling structure.

[0069] As described above, according to the present disclosure, the insulation material 20 does not need to be separately cut, and the first frame 200 and the second frame 300 of the building exterior panel supporting apparatus 50 for construction of the exterior panel 30 of the building are fixed to each other by bolt fastening. Therefore, compared to a structure fixed by welding, construction may be rapidly completed within a short time, thereby providing an effect of increasing constructability.

[0070] Thus far, the present disclosure has been described focusing on the preferred exemplary embodiments. The embodiments described above are merely illustrative for describing the distinctive technical idea pursued by the present disclosure and should be considered from an illustrative standpoint. Accordingly, a person having ordinary skill in the art to which the present disclosure pertains will understand that the present disclosure may be implemented in various modified forms without departing from the distinctive technical idea pursued by the present disclosure. Furthermore, the scope of the present disclosure should be construed as being covered by the scope of the appended claims, and all technical ideas falling within the scope of the claims should be construed as being included in the scope of the present disclosure.
