Description

Technical Field

[0001] This utility model belongs to the field of composite panel technology, and more specifically, it relates to a flame-retardant composite vertical panel structure. Background Technology

[0002] Composite panels are widely used in building decoration, furniture manufacturing, and other fields due to their lightweight structure and high strength. However, traditional composite panels typically use adhesives to bond the layers together into a single structure, a design with significant drawbacks in practical use. Firstly, in high-temperature environments such as fires, the adhesives quickly lose their bonding strength, causing the panels to delaminate and fail. Furthermore, the lack of an effective flame-retardant layer means they cannot slow the spread of fire or form a heat insulation barrier, posing serious safety hazards. Secondly, because the layers are permanently bonded, partial damage or fire damage often necessitates complete replacement. Even undamaged sections that still have usability must be discarded, resulting in resource waste and economic losses. Utility Model Content

[0034] To address the technical problems of insufficient flame retardant performance of traditional composite panels in fire environments and the inability to partially replace damaged panels, such as... Figures 1 to 5 As shown, this application proposes a flame-retardant composite vertical panel structure, which is applicable to the field of building wall panels. The flame-retardant composite vertical panel structure includes a core board 1, a flame-retardant board 2, and a decorative panel 3 stacked sequentially in a horizontal direction.

[0035] The core board 1 is made of metal materials such as steel or aluminum plates, which not only has a certain load-bearing capacity, but also effectively blocks the transmission of open flames to the back side in the event of a fire, thereby improving the fire safety of the overall structure.

[0036] The flame-retardant board 2 is positioned between the core board 1 and the decorative panel 3. Its inner side is detachably connected to the core board 1. When either the flame-retardant board 2 or the decorative panel 3 is damaged due to fire or daily use, it can be individually removed and replaced, avoiding resource waste caused by discarding the entire board. The flame-retardant board 2 can be made of materials with flame-retardant properties such as extruded polystyrene board, fire-resistant extruded polystyrene board, rigid polyurethane board, tripolyester board, phenolic board, rock wool board, foam board, polyester board, or polyether board to meet different fire resistance requirements. The decorative panel 3 is fixed to the outer side of the flame-retardant board 2 using adhesive or hot-pressing processes. Its material can be selected according to the actual application scenario, including particleboard, medium-density fiberboard, blockboard, plywood, fireproof board, finger-jointed board, straight-jointed board, ecological board, multi-layer board, cement board, gypsum board, wood-plastic composite board, or aluminum-plastic composite board, balancing decoration and functionality.

[0037] The flame-retardant composite panel structure of this application, through its layered and detachable design, improves the maintainability and economy of the composite panel while ensuring fire resistance, making it particularly suitable for building applications with high requirements for fire safety and sustainability.

[0038] like Figure 1As shown in a specific embodiment of this application, flame-retardant boards 2 are connected to opposite sides of the core board 1, forming a symmetrical flame-retardant protective layer. A decorative panel 3 is further connected to the outer side of each flame-retardant board 2, thus constituting a composite structure with double flame-retardant layers and double exterior finishes. This ensures that both sides of the composite panel possess the same flame-retardant performance and decorative effect, improving not only the overall fire safety of the panel but also enhancing the symmetry and stability of the structure. When one side of the flame-retardant board 2 or decorative panel 3 needs to be replaced due to fire or mechanical damage, only the damaged portion can be disassembled and maintained, while the composite structure on the other side remains intact and can continue to be used. This double-sided symmetrical composite structure is suitable for partition wall systems requiring double-sided decorative effects or building envelope applications with high fire resistance requirements.

[0039] like Figures 1 to 3 As shown in a specific embodiment of this application, the detachable structure between the core board 1 and the flame-retardant board 2 is as follows: the surface of the core board 1 is provided with a hook 4, and the corresponding flame-retardant board 2 is provided with a slot 5; or, the flame-retardant board 2 is provided with a hook 4, and the core board 1 is provided with a slot 5. By embedding the hook 4 into the slot 5 and fixing it, a reliable connection between the flame-retardant board 2 and the core board 1 is achieved. This connection method ensures the structural stability of the composite panel during use and facilitates quick disassembly and replacement when the flame-retardant board 2 or the decorative panel 3 is damaged. This connection method avoids the irreversibility of traditional adhesive processes and improves the maintainability and reusability of the composite panel.

[0040] like Figures 1 to 3 As shown, in a specific embodiment of this application, hooks 4 are evenly distributed at preset intervals along the vertical direction of the core board 1 or the flame-retardant board 2, forming multiple independent connection points. The arrangement of slots 5 matches that of hooks 4, and their number, spacing, and installation position correspond to those of hooks 4, ensuring that each hook 4 can be accurately embedded in the corresponding slot 5. This multi-point distributed connection structure can effectively disperse the shear force and bending moment generated during the use of the composite panel, improving the load-bearing capacity and stability of the overall structure. At the same time, the spacing design between each hook 4 ensures connection strength while avoiding stress concentration caused by excessive material concentration. This connection method can adjust the specific number and distribution density of hooks 4 and slots 5 according to actual application needs to adapt to the installation requirements of composite panels of different specifications.

[0041] like Figure 4 and Figure 5As shown in a specific embodiment of this application, the decorative panel 3 and the flame-retardant board 2 are connected by a combination of mechanical positioning and adhesive bonding. Specifically, the decorative panel 3 has a mating protrusion 6 on the side facing the flame-retardant board 2, and the flame-retardant board 2 has a corresponding mating groove 7; or, the flame-retardant board 2 has a mating protrusion 6 on its outer side, and the decorative panel 3 has a mating groove 7 on its inner side. When the decorative panel 3 is fixed to the outer side of the flame-retardant board 2 by adhesive bonding or hot pressing, the mating protrusion 6 and the mating groove 7 interlock to form a mechanical positioning structure. This structure increases the contact area of ​​the adhesive, effectively improving the interface connection strength; on the other hand, the cooperation between the protrusion and the groove achieves precise positioning, preventing the decorative panel 3 from shifting during the adhesive curing process. The cross-sectional shape of the mating protrusion 6 can be trapezoidal, rectangular, or other geometric shapes, and its dimensions maintain a transitional fit with the mating groove 7 to ensure assembly accuracy. This combination of mechanical positioning and adhesive bonding ensures the installation firmness of the decorative panel 3 and improves production efficiency.

[0042] like Figure 4 and Figure 5 As shown, in one specific embodiment of this application, the mating protrusion 6 adopts a three-dimensional grid structure design, consisting of vertical ribs 61 extending continuously in the vertical direction and horizontal ribs 62 spaced apart in the horizontal direction. The vertical ribs 61 and horizontal ribs 62 intersect to form a grid-like support structure. When the mating protrusion 6 is embedded in the mating groove 7, this grid structure can effectively increase the contact area with the adhesive, and at the same time improve the shear resistance of the connection interface through multi-directional force. The continuous extension design of the vertical ribs 61 ensures the positioning accuracy of the decorative panel 3 in the vertical direction, while the spaced arrangement of the horizontal ribs 62 ensures the connection strength in the horizontal direction and avoids excessive material concentration. The mating protrusion 6 with this three-dimensional grid structure can adjust the distribution density of the vertical ribs 61 and horizontal ribs 62 according to actual needs to adapt to the connection requirements of decorative panels 3 of different sizes.

[0043] like Figure 4 and Figure 5 As shown, in a specific embodiment of this application, the vertical ribs 61 and horizontal ribs 62 of the mating protrusion 6 are arranged in a parallel configuration. Multiple vertical ribs 61 are spaced apart horizontally, maintaining a uniform spacing between them; and / or multiple horizontal ribs 62 are spaced apart vertically, maintaining a uniform spacing between them. This multi-rib spacing design ensures the overall strength of the mating protrusion 6 while achieving a uniform distribution of adhesive on the connection interface. The specific number of vertical ribs 61 and horizontal ribs 62 can be adjusted according to the size and load-bearing requirements of the decorative panel 3, while the spacing must ensure sufficient space for adhesive flow between adjacent ribs. This arrangement improves the peel resistance of the connection and avoids stress concentration caused by excessively dense ribs, making the connection between the mating protrusion 6 and the mating groove 7 more reliable.

[0044] like Figure 4 and Figure 5 As shown, in one specific embodiment of this application, the vertical ribs 61 and horizontal ribs 62 of the mating protrusion 6 form at least one intersection node in spatial layout. This intersection structure enhances the overall rigidity of the mating protrusion 6 and prevents the ribs from undergoing local deformation under stress. When the mating protrusion 6 is embedded in the mating groove 7, the three-dimensional structure at the intersection node can provide multi-directional constraints, effectively resisting the composite stress generated by the decorative panel 3 during use. The intersection angle between the vertical ribs 61 and horizontal ribs 62 can be designed as a right angle or other suitable angle according to actual needs, and the number of intersection points can be adjusted accordingly based on the size and strength requirements of the mating protrusion 6. This intersection design, while ensuring connection reliability, optimizes the flow path of the adhesive in the gaps between the ribs, ensuring that the adhesive layer forms a uniform stress distribution.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
