Description

Technical Field

[0001] The utility model relates to the technical field of plates, in particular to a composite plate. Background Art

[0002] At present, with the acceleration of urbanization and the improvement of people's environmental awareness, traditional urban garden construction and tourist scenic spot construction increasingly emphasize the environmental protection and safety of materials. As a common paving material, plank board should not only be beautiful and economical, but also have good durability and safety performance. At present, the main plank board materials on the market are antiseptic wood, wood plastic and stone plastic.

[0003] Anticorrosive wood plank boards have been widely used due to their good natural texture and comfortable feel. However, due to the strict restrictions on new forest resources in my country and the low fire safety level of anticorrosive wood itself, coupled with the harmful substances that may be released during the anticorrosion process, the use of anticorrosive wood is restricted.

[0004] Stone plastic plank road panels are favored in the market for their high hardness and wear resistance. However, stone plastic materials are prone to brittle cracking after thermal expansion and contraction, and have a short service life, especially in outdoor scenic spots, which can easily pose a safety hazard.

[0005] As an alternative, wood-plastic boardwalk occupies a large share in the market. Wood-plastic boardwalk mainly uses PE resin and PVC resin as the base material, but there are different problems. PE resin-based boardwalk has a low fire rating and is not suitable for public facilities and tourist attractions. Although PVC resin-based boardwalk has high fire resistance, the mechanical properties are limited due to the poor compatibility between wood powder and PVC resin and low interface bonding strength.

[0006] In summary, how to provide a composite board that can be applied to plank road boards and has good environmental performance, durability and mechanical properties is a problem that needs to be urgently solved by technical personnel in this field. Utility Model Content

[0030] See also Figure 1-Figure 2 The embodiment of the utility model provides a composite plate, which is composed of a metal plate 1 and a polymer plate 2 arranged on the metal plate 1; wherein,

[0031] The upper surface of the metal plate 1 is provided with at least one first connection groove 11, and the lower surface of the polymer plate 2 is correspondingly provided with a first connection block 21 adapted to the first connection groove 11;

[0032] The interior of the metal plate 1 is hollowed out, and the bottom of the first connecting groove 11 is connected to the bottom of the metal plate 1 via a reinforcing rib 13 .

[0033] Furthermore, in the composite plate, the upper surface of the metal plate 1 is provided with five first connecting grooves 11 .

[0034] Furthermore, in the composite board, the polymer board 2 is cast, and the first connecting block 21 is a structure integrally formed when the polymer board 2 is cast.

[0035] In the specific implementation, in this embodiment, the polymer plate 2 is formed by pouring the polymer raw material on the metal plate 1 through a mold and a foaming device and naturally solidifying, that is, the polymer plate 2 is cast, and the first connecting block 21 is a structure integrally formed in the first connecting groove 11 when the polymer plate 2 is cast; of course, those skilled in the art can understand that in other embodiments, the polymer plate 2 can also be pre-formed and then installed on the metal plate 1;

[0036] The composite plate provided in this embodiment can achieve at least the following beneficial technical effects:

[0037] 1) Enhanced structural stability and load-bearing capacity

[0038] The hollow design of the metal plate 1 reduces the overall weight while maintaining the stability of the structure; the use of the reinforcing ribs 13 enhances the connection strength between the bottom of the first connecting groove 11 and the bottom of the metal plate, making the composite plate more stable when bearing loads and improving the bearing capacity;

[0039] 2) Improved connection reliability

[0040] The design of opening five first connection grooves 11 on the upper surface of the metal plate 1 allows the polymer plate 2 to form multiple points of connection with the metal plate 1, thereby increasing the reliability of the connection;

[0041] 3) Optimized mechanical properties and durability

[0042] The five evenly distributed first connecting grooves 11 are helpful to improve the overall mechanical properties of the composite plate, such as bending resistance and torsion resistance. At the same time, the combination of the metal plate 1 and the polymer plate 2 utilizes the advantages of the two materials, the high strength of the metal and the wear resistance of the polymer, so that the composite plate has better durability in long-term use.

[0043] 4) Enhanced anti-deformation and anti-fatigue performance

[0044] The hollow design of the metal plate 1 and the use of the reinforcing ribs 13 help to resist deformation caused by temperature changes or mechanical loads; the multi-point connection design also helps to reduce fatigue damage caused by repeated loads and extend the service life of the composite plate;

[0045] 5) Improved thermal insulation and acoustic performance

[0046] The combination of the metal plate 1 and the polymer plate 2 provides a certain thermal insulation performance, and the hollow design may help absorb and diffuse sound waves, thereby improving the thermal insulation and acoustic performance of the composite plate;

[0047] 6) Environmental adaptability and corrosion resistance

[0048] The combination of metal and polymer materials provides good corrosion resistance, making the composite panels suitable for a variety of environmental conditions, including humid or chemically corrosive environments;

[0049] 7) Improvement of environmental performance

[0050] Composite panels demonstrate good environmental performance through the use of recyclable metal and polymer materials, lightweight hollow design, environmentally friendly material selection, energy-saving and heat-insulating properties, and noise pollution reduction, which helps promote resource conservation, reduce environmental pollution, and support sustainable development;

[0051] The design of the composite board of this embodiment combines the advantages of multiple materials and technologies, and is suitable for application scenarios that require environmental protection, high strength, light weight, corrosion resistance and good durability. It can replace traditional solid wood floors, plastic wood floors and other products and is widely used in the construction of plank roads, outdoor floors, urban garden facilities and other fields in cultural and tourism projects.

[0052] Furthermore, in the composite plate, the cross section of the first connecting groove 11 is trapezoidal.

[0053] Furthermore, in the composite plate, the cross section of the first connecting groove 11 is an isosceles trapezoid.

[0054] In the specific implementation, in this embodiment, the cross-sections of the first connecting groove 11 and the first connecting block 21 are both trapezoidal (the lower base of the trapezoid is larger than the upper base), and are preferably isosceles trapezoidal (the two sides are equal), which brings the following technical effects to the composite board:

[0055] 1) Enhanced connection strength: The trapezoidal cross section provides a larger contact area and mechanical interlocking effect, which enhances the stability and strength of the connection between the polymer plate 2 and the metal plate 1;

[0056] 2) Improve anti-slip ability: The trapezoidal design helps to resist slip when the polymer plate 2 is connected to the metal plate 1, especially when subjected to vertical or horizontal loads;

[0057] 3) Optimize stress distribution: The trapezoidal cross section can distribute stress more effectively in the connection area, reduce stress concentration, and improve the durability of the structure;

[0058] 4) Adapting to different installation conditions: The first connection groove 11 and the first connection block 21 of trapezoidal design can be adjusted in size as needed to adapt to different installation conditions and requirements;

[0059] 5) Simplify the manufacturing process: The processing of trapezoidal cross-section is relatively simple, which can improve production efficiency and reduce manufacturing costs;

[0060] In the composite board of this embodiment, this design not only enhances the structural performance of the composite board, but also improves the convenience and reliability of its installation, while also taking into account the convenience of manufacturing.

[0061] Furthermore, in the composite plate, second connection grooves 12 are symmetrically provided at both ends of the upper surface of the metal plate 1 , and second connection blocks 22 adapted to the second connection grooves 12 are correspondingly provided at both ends of the lower surface of the polymer plate 2 .

[0062] Furthermore, in the composite board, the second connecting block 22 is a structure integrally formed when the polymer board 2 is cast.

[0063] In specific implementation, in this embodiment, the second connecting block 22 is a structure integrally formed in the second connecting groove 12 when the polymer board 2 is cast and formed. In this embodiment, the second connecting grooves 12 are symmetrically opened at both ends of the upper surface of the metal plate 1. This embodiment can further increase the connection reliability between the polymer board 2 and the metal plate 1 through the connection between the second connecting block 22 and the second connecting groove 12. The symmetrically arranged second connecting grooves 12 and the second connecting blocks 22 provide symmetrically distributed connection points, which helps the composite plate to disperse the load and reduce local stress concentration.

[0064] Furthermore, in the composite plate, the cross section of the second connecting groove 12 is trapezoidal.

[0065] Furthermore, in the composite plate, the cross section of the second connecting groove 12 is a right-angled trapezoid.

[0066] In the specific implementation, in this embodiment, the cross-sections of the second connecting groove 12 and the second connecting block 22 are both trapezoidal (the lower base of the trapezoid is larger than the upper base), and are preferably right-angled trapezoids (the side with the waist vertically facing outwards), which further enhances the overall performance of the composite board.

[0067] Furthermore, in the composite plate, mounting grooves 14 are symmetrically provided on both sides of the metal plate 1 .

[0068] In specific implementation, in this embodiment, the two composite panels can be connected to the mounting grooves 14 of the two panels through a fastener to achieve connection and fixation between the two composite panels, thereby achieving rapid installation and removal between the two composite panels.

[0069] Furthermore, in the composite board, the metal plate 1 is made of aluminum, and the polymer plate 2 is made of PU.

[0070] In specific implementation, in this embodiment, the metal plate 1 is made of aluminum, and the polymer plate 2 is made of PU (polyurethane). The design of the composite plate in this embodiment has the following technical effects:

[0071] 1) Lightweight: Aluminum material has a lower density, which makes the metal plate 1 lightweight, reduces the weight of the overall composite plate, and reduces energy consumption during transportation and installation;

[0072] 2) High recycling value: Aluminum is a material with high recycling value and can be recycled many times without losing its performance, which helps reduce the need to mine new raw materials and reduce environmental impact;

[0074] 4) Good thermal conductivity: Aluminum has good thermal conductivity, which helps improve the thermal management performance of the composite panel and can provide insulation or heat dissipation functions in some applications;

[0075] 5) Environmentally friendly materials: PU material is a highly plastic and durable synthetic material. Compared with some plastics, PU may use less harmful chemicals in the production process and has good recycling potential;

[0076] 6) Excellent mechanical properties: PU material has good elasticity and toughness. When used in combination with aluminum metal plates, it can provide excellent impact resistance and fatigue resistance.

[0077] 7) Durability: The durability of PU materials helps to extend the service life of composite panels, reducing the frequency of product replacement and the generation of waste materials;

[0078] 8) Environmental adaptability: PU materials can adapt to different environmental conditions, including water resistance, weather resistance and chemical resistance, making composite panels suitable for a wider range of application scenarios;

[0079] 9) Aesthetics: Both aluminum and PU materials can provide good surface treatment options, such as spraying, anodizing, etc., which increases the aesthetics and design flexibility of the composite panels;

[0082] In the specific implementation, in this embodiment, a design in which a plurality of strip-shaped patterns are evenly arranged on the upper surface of the metal plate 1 brings the following technical effects to the composite plate:

[0083] 1) Increase the friction coefficient: The striped pattern increases the surface roughness of the metal plate 1, thereby increasing the friction coefficient when it contacts the polymer plate 2 (during casting), and enhancing the mechanical bite between the two plates;

[0084] 2) Increase structural strength: The presence of the stripe pattern can increase the local stiffness and strength of the metal plate 1 to a certain extent;
