Description

Technology Field

[0001] The present invention relates to a building panel structure, and more specifically, to a building panel system in which a wall is formed by assembling a plurality of panel modules including an insulating core and a finishing plate, wherein a first metal support member and a second metal support member disposed on the side of the panel module are interlocked to perform a structural support function between the panel modules, a horizontal connecting member is provided on the upper side to align and connect the panel modules, and a space finishing material that reinforces structural rigidity is filled in the space between the metal support members to form a self-supporting structure without a separate structural column and improve constructability. Background Technology

[0003] Various panels containing insulation cores and finishing panels are widely used at construction sites for exterior walls, interior walls, partitions, partition walls for factories and warehouses, temporary structures, and modular buildings. These panels are advantageous for shortening construction time by ensuring lightweight design and thermal insulation performance, and their application scope is gradually expanding due to the advantage of maintaining consistent construction quality through a method of manufacturing them to standard specifications in a factory and assembling them on-site.

[0004] However, conventional panel construction methods often make it difficult to secure sufficient structural support using only the panels themselves; therefore, a structure has generally been adopted in which separate vertical and horizontal support members are installed before the panels are fastened. For instance, a common method has been to construct a wall by first erecting a vertical frame, such as steel or lightweight steel studs, and then additionally placing horizontal bracing or reinforcing members, followed by fastening the panels with screws or brackets. Furthermore, at the joints between panels, additional components such as connecting brackets, joint members, and moldings have been frequently used to align the panels and seal the gaps.

[0005] Conventional structures of this type require horizontal and vertical support bars or frame members to support the panels, resulting in a problem where dead space equivalent to the frame thickness occurs on the interior or exterior of the wall after construction. In particular, in indoor spaces, vertical frames such as lightweight steel studs increase the wall thickness, while horizontal reinforcements limit the space for plumbing and electrical wiring or require additional finishing structures, thereby reducing space utilization. Consequently, even for buildings with the same external dimensions, the actual usable effective area decreases.

[0006] In addition, the process of installing horizontal and vertical support bars itself poses a problem by increasing the number of steps and prolonging the work time. In other words, conventionally, multi-stage processes such as frame installation, horizontal reinforcement installation, panel alignment and temporary fixing, panel fastening, joint finishing, and gap filling must be carried out sequentially, and each process involves the input of manpower and equipment. In particular, since the verticality of the vertical frame and the level of the horizontal reinforcement must be aligned first, a high level of worker skill is required, and remeasurements and re-construction are often repeated depending on site conditions, which becomes a major cause of construction delays.

[0007] Furthermore, the installation of support bars and frame components contributes to increased material costs. In addition to the cost of the panels themselves, extra materials such as steel frames, connecting brackets, fasteners, reinforcing members, separate corner components, and finishing materials are required; the cost burden increases significantly as the construction area grows. Moreover, labor costs for frame installation and fastening increase, and as the process lengthens, problems arise regarding rising equipment rental and site management costs.

[0008] Furthermore, conventional structures suffer from the problem of difficulty in reliably ensuring panel alignment and joint quality. In methods where panels are fastened to a frame, the panel position can vary depending on the worker's assembly sequence and fastening status, and gaps or unevenness are prone to occur at the joints. This raises concerns about uneven finishing quality after construction or a decline in airtightness and thermal insulation performance. Additionally, if joint gaps are not sufficiently sealed, issues such as condensation, leakage, and drafts may occur, directly impacting user satisfaction and maintenance costs. Moreover, conventional panel installation methods have limitations in terms of structural stability. In structures where the frame and panels exist as separate components joined by fastening, the load transfer path becomes complex, leading to stress concentration at the fastening points or the possibility of loosening during long-term use. In particular, in environments subject to repeated loading, vibration, or thermal expansion and contraction caused by temperature changes, loosening of the fastening points and deformation of the joints may occur, potentially leading to a decrease in wall rigidity or the occurrence of cracks and deformation.

[0009] In particular, conventional methods are even more inefficient at construction sites where working conditions are limited, such as those with cramped environments, high-rise buildings, or interior remodeling. It is difficult to secure the workspace required for frame installation, and the process of bringing in and handling long support bars and reinforcing materials complicates workflow, which increases the risk of safety accidents. Furthermore, there is a problem of reduced on-site work efficiency as temporary jigs or additional personnel are sometimes required to support panels during the process of fastening them after frame installation.

[0010] Therefore, considering these limitations of conventional technology, there is a need to develop a new technology that allows for the formation of a self-supporting structure without the need for separate horizontal and vertical support bars by having metal support members placed on the sides of the panel modules interlock and connect to perform a vertical structural support function between the panels, providing a horizontal connecting member at the top to align and connect the panel modules, and enabling the internal space between the metal support members to be finished and reinforced for rigidity. This enables the reduction of assembly time, expansion of the workspace, and improvement of user space utilization after construction. Prior art literature

[0049] A modular building panel assembly having a self-supporting metal support joint structure related to one embodiment of the present invention for realizing the above-described problem is configured such that a plurality of panel modules (100) including an insulating core (110) and a finishing plate (120) are assembled to form a wall, and a first metal support member (210) and a second metal support member (220) disposed on the side of the panel module (100) are interlocked to form a support structure (200), thereby performing a vertical structural support function between the panel modules (100), a horizontal connecting member (300) is installed on the upper part of the plurality of panel modules (100) to mutually connect and align the panel modules (100) and the support structure (200), and the internal space between the first metal support member (210) and the second metal support member (220) is finished by a space finishing material (400) and is configured to reinforce structural rigidity.

[0050] First, the panel module (100) includes a finishing plate (120) disposed on at least one side of the insulation core (110). The panel module (100) can be applied as a building wall, partition, exterior or interior panel, and it is preferable that it be formed into a rectangular plate so that repeated construction is possible in a module unit. The thickness, width, and length of the panel module (100) may be selected according to the on-site application structure, required insulation performance, transportation conditions, etc., but generally, it is advantageous to standardize them to a certain size considering constructability and transportability.

[0051] The insulation core (110) is a key component responsible for insulation and lightweighting of the panel module (100) and may include an XPS board, an XR board, a PF board, or an XPS board. The XR board may be designed to have a low thermal conductivity as a core material prioritizing insulation performance, and the PF board may be designed with a composition that considers fire safety as a core material that enhances flame retardant or non-combustible performance. The density of the core material may vary depending on the purpose of application, but for example, the XR board may be composed of a relatively low density for lightweight and thermal insulation performance, and the PF board may be composed of a structure with a relatively high density or increased inorganic filler content to ensure flame retardancy and heat resistance stability. It is desirable that the strength of the core material be designed so that compressive strength and bending strength are secured above a certain level to prevent damage during transportation and construction processes and to ensure planar rigidity of the panel. The non-combustibility or flame retardancy of the core material may vary depending on the building's intended use and relevant regulations, and PF boards may contain flame-retardant additives, inorganic fillers, or non-combustible components to suppress flame spread and smoke generation. XPS boards are selected to enhance the stability and thermal insulation of buildings by improving flame retardancy and non-combustibility, as well as strength and density. Additionally, the core material may be formed to have a closed-cell structure or a micro-pore structure for thermal insulation, and a surface coating layer or a vapor barrier may be added to reduce moisture absorption and ensure dimensional stability during long-term use.

[0052] A finishing plate (120) is placed on at least one surface of the core material (110) to provide surface rigidity, impact resistance, weather resistance, and finishing quality of the panel. The finishing plate (120) may be formed from a cement board, concrete plate, fiber-reinforced cement board, metal plate, inorganic board, or gypsum-based board, and for exterior use, a material with excellent weather resistance and water resistance may be selected, and for interior use, a material with excellent workability and finishing properties may be selected. The material and thickness of the finishing plate (120) may be selected according to the required strength, fire resistance performance, and surface finishing type, and a fiber reinforcement layer or a mesh reinforcement layer may be included to prevent cracking and improve impact resistance.

[0053] Here, the shape of the panel module (100) is basically a flat plate, but to increase corner bonding strength, a stopper, an uneven surface, or a groove structure may be added to the side, and to increase surface finish quality, a coating layer, a waterproof layer, a texture layer, etc. may be formed on the outer surface.

[0054] The first metal support member (210) and the second metal support member (220) are each placed on the side of the panel module (100) and are made of metal profiles extending in the vertical length direction. When the two support members are combined, they are placed facing each other and interlocked, thereby forming a support structure (200) that performs a vertical structural support function between the panel modules (100).

[0055] The first and second metal support members (210, 220) are preferably formed as extruded or bent profiles having a uniform cross-section so that they can be repeatedly assembled at the construction site. To ensure structural rigidity and durability, the metal support members may be composed of steel plates, hot-dip galvanized steel plates, aluminum alloys, stainless steel, etc., and surface treatments such as galvanizing, powder coating, and anodizing may be applied considering the corrosive environment. In particular, when applied to exterior surfaces, surface treatments that consider anti-corrosion performance and weather resistance are preferred.

[0056] At this time, it is desirable for the interlocking joint structure to ensure joint stability without the need for fasteners, and structures such as a locking part, insertion part, hook shape, or slide joint part may be applied to generate joint force during snap jointing. This enables the realization of a structure that performs the function of a column while the panel and support are assembled without the conventional frame installation process.

[0057] Additionally, a horizontal connecting member (300) is installed on the upper portion of a plurality of panel modules (100) to interconnect the panel modules (100) and the support structure (200) and to align their positions. The horizontal connecting member (300) is preferably formed as a metal rail or a metal channel structure and serves to align the upper portion of the panel modules (100) according to a certain standard to reduce assembly errors and suppress lateral shaking from the upper portion. The horizontal connecting member (300) can be formed from steel plates, aluminum, stainless steel, etc., and if necessary, ribs can be formed on the inner side to increase bending rigidity.

[0058] Here, the space finishing material (400) is provided to finish the internal space formed between the first metal support member (210) and the second metal support member (220) and to reinforce structural rigidity. The space finishing material (400) fills the gaps to improve airtightness and sound insulation, and suppresses local deformation of the metal support member to increase the rigidity of the support structure (200). The space finishing material (400) may be formed from mortar, grout, urethane foam, or fireproof filler, and when applied to the exterior, a material that takes into account waterproofing and weather resistance performance may be selected.

[0059] Meanwhile, the first metal support member (210) and the second metal support member (220) may be formed with a cross-section in the shape of an L, an L-shape, a C-shape, or a box shape, and are provided to interlock with each other to form a closed cross-section or a partially closed cross-section structure. The closed cross-section or partially closed cross-section structure has superior torsional rigidity and buckling resistance compared to an open cross-section, thereby improving the structural support performance as a support structure (200). In addition, the two support members include a locking part or an insertion part that interlocks with each other, and a support projection or support ledge is formed on the inner surface to support the side of the panel module (100) so as to prevent the panel module (100) from deviating in the horizontal direction.

[0060] This structure provides an automatic alignment effect during assembly, improves construction precision by suppressing panel slippage within the support, and is advantageous for maintaining joint stability against repetitive loads or vibrations during long-term use. The support protrusions or ledges may be formed in the form of continuous ribs or as protrusions that are repeated at regular intervals, and various forms can be adopted to consider convenience during on-site construction.

[0061] Meanwhile, the panel module (100) is formed as a sandwich structure in which an insulating core (110) is placed between the first finishing plate (121) and the second finishing plate (122). The sandwich structure increases the bending rigidity of the panel and is advantageous for achieving lightweighting and thermal insulation performance compared to the same thickness. The first finishing plate (121) and the second finishing plate (122) may be made of the same material, or they may be selected from different materials depending on the performance requirements of the outer and inner sides.

[0062] At this time, an insertion groove or a coupling groove may be formed on the side of the panel module (100) to be inserted into the first metal support member (210) or the second metal support member (220). This groove structure has the effect of increasing the coupling area between the panel and the metal support member to improve coupling rigidity, preventing the panel from shifting position during the assembly process, and reducing the occurrence of gaps in the coupling part to improve airtightness and finishing quality.

[0063] Additionally, the horizontal connecting member (300) is formed in the shape of a metal rail or a metal channel and may include a position alignment projection or a position alignment groove for aligning the panel position. The position alignment structure reduces assembly errors by aligning the reference line on the upper part of the panel and improves the finishing quality by suppressing the occurrence of gaps at the upper part. The space finishing material (400) may be formed from any one of mortar, grout, urethane foam, or fireproof filler, and may be selected to enhance fire resistance or waterproofing performance depending on the application environment.

[0064] In addition, on the inner surface of the first and second metal support members (210, 220), a plurality of protruding connecting parts (230) are formed to be spaced apart in the vertical direction to support the side of the panel module (100) and align its position. The protruding connecting parts (230) contact the side of the panel module (100) and perform the function of preventing the panel from moving horizontally within the metal support member. The protruding connecting parts (230) maintain a constant insertion depth and position of the panel during assembly and provide local support points for the side of the panel to reduce sagging or gaps in the panel during long-term use. The shape of the protruding connecting parts (230) can be various forms, such as semicircular, square rib, or tapered protrusions, and the corners may be rounded to prevent damage to the panel, and may be formed to include fine irregularities to increase friction.

[0065] Additionally, the panel module (100) may include a first panel module (100a) and a second panel module (100b) arranged in a direction perpendicular to each other, and a first and second metal support member (210, 220) is interlocked between the two panels to form a corner support structure (250). The corner support structure (250) serves to increase structural rigidity at the corner of the wall and to improve wall stability by suppressing the spreading or twisting of the corner. By providing a metal support member extending in a perpendicular direction to be fitted together, the assembly of the corner is simplified and the alignment quality of the corner is improved.

[0066] Additionally, an upper finishing cap (500) formed to cover the upper portion of a plurality of panel modules (100) may be further provided on the upper portion of the horizontal connecting member (300). The upper finishing cap (500) is configured to align and fix the upper position of the panel by including an insertion projection or a locking projection that is inserted and coupled to the horizontal connecting member (300). The upper finishing cap (500) can provide effects such as preventing rainwater ingress, improving the quality of the upper finishing, protecting the upper corners of the panel, and improving upper airtightness. The upper finishing cap (500) may be formed of metal, synthetic resin, flame-retardant resin, or composite material, and may include a UV stabilizer to ensure weather resistance when applied to the exterior.

[0067] In the case of constructing the exterior walls of large-area buildings such as warehouses or factories, conventionally, a process of installing steel columns and horizontal reinforcing members followed by fastening panels was required. However, according to the present invention, a separate frame installation process can be reduced by forming a support structure (200) by interlocking the first metal support member (210) and the second metal support member (220) while arranging the panel modules (100). Additionally, by installing a horizontal connecting member (300) on the top and aligning it based on the top of the panel, the verticality and horizontality of the entire wall can be easily secured, and sound insulation, airtightness, and rigidity can be simultaneously secured by filling the space finishing material (400) into the internal space of the support. In the corner section, a corner support structure (250) can be applied to secure corner stability, and an upper finishing cap (500) can be applied to the top to improve finishing and waterproofing. As another example, when configuring interior partitions, the space occupied by horizontal and vertical frames can be reduced, allowing for an expansion of the usable space within the same area; furthermore, ease of assembly and disassembly makes it advantageous for remodeling or space reorganization work.

[0068] Meanwhile, the interlocking joint portions of the first metal support member (210) and the second metal support member (220) are configured to further provide an elastic fastening portion or a snap joint portion to maintain a fastening force or a connected state when connected, and it is preferable that the internal space of the first metal support member (210) and the second metal support member (220) is further provided with a fire-resistant reinforcing material or a fire-resistant coating layer to improve fire-resistant performance.

[0069] Here, the space finishing material (400) includes a flame-retardant foam material that hardens after foaming and hermetically fills the internal space of the support structure (200), and the horizontal connecting member (300) is configured to further include a compression part or a fastening part that presses and fixes the upper part of the panel module (100).

[0070] Additionally, the upper end cap (500) is configured to include a drainage path or a drip edge to prevent moisture entering from the outside from penetrating into the panel.

[0072] The present invention has been described above through a preferred embodiment. However, the above-described embodiment is merely an illustrative explanation of the technical concept of the present invention, and it will be understood by those skilled in the art that various changes are possible within the scope of the technical concept of the present invention. Accordingly, the scope of protection of the present invention should be interpreted by the matters described in the patent claims rather than by specific embodiments, and all technical concepts within the same or similar scope should also be interpreted as being included within the scope of rights of the present invention.
