Description

Technical Field

[0001] The utility model belongs to the technical field of real grass planting, and particularly relates to a panel composite reinforcement structure. Background Art

[0002] In the field of construction engineering, as a new type of building material, composite panels are widely used in structures such as building exterior walls, table panels, rock slabs, and partition layers due to their excellent properties such as light weight, high strength, sound insulation, and heat insulation. Among them, the honeycomb panel technology, as an important composite panel technology, has attracted much attention in the industry with its unique structural form and excellent performance. However, the existing honeycomb panel technology still has many deficiencies, which limit its further application and promotion in the field of construction engineering.

[0003] Currently, the commonly used honeycomb panels mainly include paper honeycomb panels, fiberglass honeycomb panels, and aluminum honeycomb panels. Paper honeycomb panels are greatly limited in practical applications due to their low strength, poor moisture resistance, easy aging, and poor fire resistance. Although fiberglass honeycomb panels have improved strength to a certain extent, they still have problems such as low impact strength and easy aging. The aluminum honeycomb panel is formed by bonding an aluminum honeycomb core and an aluminum alloy panel. Although the aluminum honeycomb core is commonly made of aluminum foil, it is soft and has low strength, and usually requires a relatively thick aluminum alloy panel to provide sufficient strength and stiffness, which undoubtedly increases the self-weight of the honeycomb panel and brings inconvenience to construction and installation.

[0004] More importantly, whether it is paper honeycomb, fiberglass honeycomb, or aluminum honeycomb, when used as a building exterior wall, table panel, rock slab, or partition layer, it cannot withstand large longitudinal impacts, which greatly limits its application in occasions where certain impact loads need to be borne. In addition, during the composite process of the existing honeycomb panel and the panel, there are also defects such as high composite cost and complex composite process, which not only increase the production cost but also reduce the production efficiency, and are not conducive to the popularization and application of honeycomb panel technology.

[0005] Therefore, in view of the many deficiencies of the existing honeycomb panel technology, it is necessary to carry out technological innovation and improvement to develop a panel composite reinforcement structure to improve its properties such as strength, while reducing the composite cost and simplifying the composite process, so as to meet the urgent needs of the construction engineering field for high-performance and low-cost composite panels.

Detailed Embodiments

[0023] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] In order to improve the bearing strength of the panel, please refer to Figures 1 to 4 , the present utility model designs a panel composite reinforcement structure, including a panel 1, and a reinforcement layer 2 is compounded on the back of the panel. In the panel composite structure, the introduction of the reinforcement layer has significant necessity and technical effects. For existing hard and brittle panels, such as marble countertops, rock slabs, large ceramic tiles, glass panels, etc., although these materials have excellent appearance and certain service performance, they generally have the disadvantages of being fragile and prone to bursting, and are easily damaged when subjected to a large external force impact, seriously affecting the use effect and safety.

[0025] At the same time, for materials such as stainless steel panels and plastic plates, although they have certain strength and toughness, they still face the problems of insufficient flexural strength and easy deformation in actual applications. Especially in occasions where large loads need to be borne or frequent forces are applied, the risk of deformation and damage of these panels increases significantly.

[0026] Therefore, it is particularly necessary to composite an enhanced layer on the back of the panel. The main function of the enhanced layer is to improve the overall strength and stiffness of the panel, effectively resist external force impacts and load effects, prevent the panel from being damaged, deformed, or even burst. By reasonably selecting and designing the materials and structures of the enhanced layer, the comprehensive performance of the panel can be improved, making it have higher safety and durability while meeting the usage requirements.

[0027] The enhanced layer includes a thermoplastic honeycomb reinforcement module 2-1 or a reinforcement plate formed by splicing several honeycomb reinforcement modules (please refer to Figure 7 ), and the honeycomb reinforcement module is an integrally formed double-layer honeycomb panel; the honeycomb chambers 2-2 of the double-layer honeycomb panel are arranged in a staggered manner, and the upper and lower honeycomb chambers are connected; in the traditional honeycomb panel design, a single-layer honeycomb structure is usually adopted. Although this structure has certain strength and stability, its performance is often limited when facing complex and variable loads and environmental conditions. Especially in occasions where large impacts or loads need to be borne, the single-layer honeycomb structure is prone to deformation and damage, thus affecting the overall performance and service life.

[0028] In contrast, the enhanced layer with a double-layer staggered honeycomb design has more significant strength advantages. The honeycomb chambers of the double-layer honeycomb panel are arranged in a staggered manner. This unique design enables the honeycomb panel to better disperse and transfer stress when bearing loads, thus effectively resisting external force impacts and deformations. At the same time, the double-layer structure also provides better support and stability, significantly improving the overall performance of the honeycomb panel.

[0029] Specifically, the double-layer staggered honeycomb design realizes the full utilization and optimization of material properties by increasing the number of layers of the honeycomb panel and changing the layout of the honeycomb chambers. This design not only improves the strength and stiffness of the honeycomb panel but also increases its impact resistance and wear resistance. Therefore, under the same conditions, the enhanced layer with a double-layer staggered honeycomb design has higher load-bearing capacity and better durability compared to the traditional single-layer honeycomb structure.

[0030] In summary, the double-layer staggered honeycomb design has significant advantages in terms of strength, and can effectively improve the overall performance and service life of the panel composite structure.

[0031] One side of the honeycomb reinforcement module or the reinforcement plate (please refer to Figure 3 and Figure 5 ) or both sides (please refer to Figure 6)The non-woven fabric layer 2-3 is composite-welded by ultrasonic waves; the design of the honeycomb reinforcement module or reinforcement plate in the present utility model has extremely high flexibility and a wide range of application scenarios. When choosing to composite one side with the non-woven fabric layer, this layer is closely bonded to the panel, providing excellent structural strength and stability. And the exposed honeycomb chambers can be used for multi-functional applications according to specific requirements, such as filling thermal insulation materials to enhance the thermal insulation performance, or directly combining with the mortar layer of the structural surface layer to form an integrated structural system, further improving the strength and durability of the overall structure.

[0032] When using double-sided composite non-woven fabric layers, the technical effect of the present utility model is more remarkable. One layer of non-woven fabric is closely bonded to the panel, ensuring the stability and firmness of the structure. And on the other side, due to the composite non-woven fabric layer, it has more excellent bonding performance and can be easily applied to multiple complex scenarios, such as the already constructed concrete surface layer, wooden surface layer, metal surface layer, etc. This design not only simplifies the construction process, reduces the construction difficulty, but also improves the adaptability and durability of the overall structure.

[0033] The surface of the non-woven fabric layer is coated with an adhesive layer 2-4, and the adhesive layer is bonded to the back of the panel. Polyurethane adhesive or epoxy resin adhesive is selected as the bonding material between the panel and the non-woven fabric layer, and its foaming effect brings significant technical advantages. These two adhesives can form tiny bubbles during the curing process. These bubbles not only play a buffering role, but also can effectively disperse and absorb the impact force received by the panel, thereby improving the impact resistance of the overall structure. At the same time, the foaming effect also increases the volume of the adhesive, making it more fully fill the tiny gaps between the non-woven fabric layer and the panel, forming a more firm bond. This enhanced bonding effect not only improves the stability and durability of the panel composite reinforcement structure, but also effectively prevents the structural failure problem caused by weak bonding. Therefore, choosing polyurethane or epoxy resin adhesive with a foaming effect provides better performance and a wider application prospect for the panel composite reinforcement structure.

[0034] In the traditional bonding structure between the panel and the reinforcement layer, adhesives are often directly used to bond the two, and this approach may have the problem of weak bonding in some cases, affecting the stability and durability of the overall structure. In this design, one side or both sides of the honeycomb reinforcement module or reinforcement plate are composite-welded with the non-woven fabric layer by ultrasonic waves, and this innovative design brings significant effects and advantages.

[0035] The non-woven fabric layer has good compatibility, and its fiber structure enables it to form a firm bond with various panel boards through adhesives. Whether it is hard and brittle marble, rock board, or easily deformable stainless steel, plastic board, the non-woven fabric layer can form a good bond with them, effectively breaking the problem of weak bonding existing in traditional single-layer bonding.

[0036] In addition, the presence of the non-woven fabric layer also plays a role in buffering and dispersing stress. When the panel is subjected to external impact, the non-woven fabric layer can absorb and disperse part of the stress, reducing the direct impact on the reinforcement layer, thereby further improving the impact resistance and durability of the overall structure.

[0037] At the same time, the introduction of the non-woven fabric layer also simplifies the production process and improves production efficiency. Since the non-woven fabric layer and the honeycomb reinforcement module or the reinforcement plate are composite by ultrasonic welding, this process can be quickly completed on the production line without additional bonding steps, thereby reducing production costs and improving production efficiency.

[0038] In summary, the composite design of the non-woven fabric layer not only solves the problem of poor bonding in traditional single-layer bonding, but also improves the impact resistance and durability of the overall structure, simplifies the production process, and reduces production costs.

[0039] Preferably, reinforcing ribs 2-7 are provided on the side walls of the honeycomb chambers. The arrangement of the reinforcing ribs significantly enhances the side wall strength of the honeycomb chambers, enabling them to better resist deformation and breakage when facing external impact or load. This design not only improves the overall stability and durability of the honeycomb reinforcement module, but also effectively extends the service life of the panel composite reinforcement structure. By optimizing the layout and size of the reinforcing ribs, the performance of the honeycomb chambers can be further customized and enhanced to meet the requirements of different application scenarios.

[0040] Preferably, splicing parts are provided around the honeycomb reinforcement module. For example, connection holes 2-5 and connection pins 2-6, or the method of grooves and buckles are used for connection; the setting of the splicing parts enables multiple honeycomb reinforcement modules to be conveniently spliced together to form a larger-area reinforcement plate. This design not only improves the production flexibility, but also enables the panel composite reinforcement structure to adapt to different sizes and shapes of application scenarios. At the same time, the splicing parts can also serve as connection points between the modules. Through reasonable connection design, the strength and stability of the overall structure can be further improved. In practical applications, the presence of the splicing parts can also simplify the installation process and reduce the construction difficulty and cost.

[0041] Preferably, the non-woven fabric layer on the side bonded to the panel is a breathable non-woven fabric.

[0042] In the panel composite reinforcement structure, the non-woven fabric layer on the side bonded to the panel adopts a breathable design, and this technical feature brings significant technical effects.

[0043] First, the breathable non-woven fabric layer facilitates air exhaust during the bonding and lamination process. In traditional bonding processes, in order to exhaust air during bonding, it is often necessary to punch air holes in aluminum plates or other panels. This not only increases the complexity of the production process but may also affect the overall aesthetics and performance of the panel. The design of the breathable non-woven fabric layer effectively solves this problem. It can naturally exhaust air during the bonding process without the need for additional air holes, thus simplifying the production process.

[0044] Second, the breathable non-woven fabric layer also facilitates the infiltration of the adhesive. Due to the good breathability of the non-woven fabric layer, the adhesive can infiltrate the non-woven fabric layer more fully after being applied, forming a stronger bond. This full infiltration not only improves the bonding strength of the adhesive but also enhances the stability and durability of the overall structure.

[0045] Finally, from a broader perspective of application, the design of the breathable non-woven fabric layer also improves the applicability and flexibility of the panel composite reinforcement structure. Whether in home decoration, building materials, or other industrial fields, this design can meet the requirements of different application scenarios, providing a broader space for the application of the panel composite reinforcement structure.

[0046] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present utility model, such as the geometric shape and material of the honeycomb reinforcement module, and the provision of a splicing portion for splicing between adjacent honeycomb reinforcement modules, etc., shall all be included within the protection scope of the present utility model.
