Description

Technical Field

[0001] The utility model relates to the technical field of construction and plate materials, in particular to a torsion-resistant composite plate material. Background Art

[0002] Building materials and panels refer to various sheet materials used for interior and exterior decorative structures, construction, and shelving. These materials are not only practical but also visually appealing. Common examples include stainless steel, aluminum, copper, glass, composite, stone, and ceramic.

[0003] Traditional composite panels are usually made by simply splicing multiple layers of materials. In order to meet construction requirements, the thickness of the panel materials is usually very thick. During construction, this will reduce the usable area of ​​the building and increase the load-bearing capacity of the entire building. Reducing the thickness of the panel will not achieve the required structural strength, and it is also necessary to pre-lay steel bars during construction to increase the structural strength. Utility Model Content

[0004] The purpose of the utility model is to solve the performance problems of existing boards such as low structural strength, poor flatness, uneven visual reflection, etc. after lightweighting, and to provide a torsion-resistant composite board.

[0009] Bottom layer; the bottom layer is located under the second adhesive layer.

[0010] Furthermore, the thickness of the surface layer is set to 0.3-20 mm; the thickness of the honeycomb layer is set to 5-40 mm; and the thickness of the bottom layer is 0.3-20 mm.

[0011] Furthermore, a first groove is provided on the bottom surface of the surface layer; the first bonding layer, the honeycomb layer, the second bonding layer and the bottom layer are located in the first groove.

[0012] Furthermore, a second groove is provided on the upper surface of the bottom layer; the first bonding layer, the honeycomb layer and the second bonding layer are located in the second groove; and the bottom layer is integrally buckled inside the first groove.

[0013] Furthermore, the overall thickness of the first bonding layer, the honeycomb layer and the second bonding layer is equal to the depth of the second groove.

[0016] S1: a first groove is formed on the lower surface of the surface layer, and after the first groove is formed, a fixing groove is formed in an array on the surface of the first groove;

[0017] S2: Grooving the upper surface of the first adhesive layer to form a fixing block, with the position of the fixing block matching the fixing groove;

[0018] S3: Opening a second groove on the upper surface of the bottom layer and applying glue in the second groove;

[0019] S4: buckle the second adhesive layer into the second groove and press it into place;

[0020] S5: evenly apply adhesive to the upper surface of the second adhesive layer, and place the honeycomb layer on the upper surface of the second adhesive layer;

[0025] By setting the first groove and the second groove of the surface layer and the bottom layer, the strength can be increased through the structure. When subjected to force, the borders of the edge of the surface layer and the bottom layer can be subjected to force first. Since it is in the border part, it will not affect the overall strength of the board. At the same time, since the bottom layer is buckled in the first groove of the surface layer, the tightness of the board is increased and the thickness of the board is reduced. This improves the structural strength, flatness, and uniform reflection of the board while reducing the thickness of the board, increasing the aesthetics of the board and the strength and shock resistance of the overall structure.

[0030] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that, unless conflicting, the following embodiments and features within these embodiments may be combined or selectively combined.

[0031] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. Therefore, the drawings only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complex or simpler.

[0032] Example 1

[0033] like Figures 1-3 As shown:

[0034] A torsion-resistant composite plate comprising

[0035] Surface layer 1; a first adhesive layer 4 is provided on the lower side of the surface layer 1;

[0036] Honeycomb layer 2; the honeycomb layer 2 is located under the first bonding layer 4;

[0037] By providing the honeycomb layer 2, the special structure of the honeycomb layer 2 will collapse downward when subjected to force, and buffer the force. At the same time, the force on the entire plate is evenly distributed to various parts of the plate, making the plate more evenly stressed. The plate will not be deformed due to a single force on a certain part, causing the entire plate to break. This increases the structural strength of the plate and improves the torsional resistance of the plate.

[0038] Specifically, experimental data show that in this solution, the honeycomb panel 2 is preferably set to an aluminum structure. The purpose is that the aluminum material has high toughness and lightness, can bear more loads and is lighter in weight;

[0039] A second bonding layer 5 is provided on the lower side of the honeycomb layer 2;

[0040] The bottom layer 3 is located under the second adhesive layer 5 .

[0041] The thickness of the surface layer 1 is set to 0.3-20 mm; the thickness of the honeycomb layer 2 is set to 5-40 mm; the thickness of the bottom layer 3 is 0.3-20 mm. The bottom surface of the surface layer 1 is provided with a first groove 11; the first adhesive layer 4, honeycomb layer 2, second adhesive layer 5, and bottom layer 3 are located in the first groove 11.

[0042] The upper surface of the bottom layer 3 is provided with a second groove 51 ; the first bonding layer 4 , the honeycomb layer 2 and the second bonding layer 5 are located in the second groove 51 ; the bottom layer 3 is integrally buckled inside the first groove 11 .

[0043] The overall thickness of the first bonding layer 4 , the honeycomb layer 2 and the second bonding layer 5 is equal to the depth of the second groove 51 .

[0044] The upper surface of the first adhesive layer 4 is provided with an array of fixing blocks 41 ; the lower surface of the surface layer 1 is provided with fixing grooves 12 ; the fixing blocks 41 can be snapped into the fixing grooves 12 .

[0045] The purpose of providing the fixing groove 12 and the fixing block 41 is to increase the stability of the plate. Since the plate may be subjected to force at the frames on both sides, the plate may slip when the frames are damaged. Therefore, the fixing block 41 and the fixing groove 12 are provided to engage with each other, so that the stability of the plate connection can be increased through the structure after the frames are damaged.

[0046] By setting the first groove 11 and the second groove 51 of the surface layer 1 and the bottom layer 3, the strength can be increased through the structure. When subjected to force, the frame at the edge of the surface layer 1 and the bottom layer 3 can be subjected to force first. Since it is in the frame part, it will not affect the overall strength of the board. At the same time, since the bottom layer 3 is buckled in the first groove 11 of the surface layer 1, the tightness of the board is increased and the thickness of the board is reduced. This makes the board have a reduced thickness while improving the structural strength, and increases the aesthetics, flatness, and uniform visual reflection of the board.

[0047] A production process for torsion-resistant composite panels, comprising:

[0048] S1: a first groove is formed on the lower surface of the surface layer, and after the first groove is formed, a fixing groove is formed in an array on the surface of the first groove;

[0049] S2: Grooving the upper surface of the first adhesive layer to form a fixing block, with the position of the fixing block matching the fixing groove;

[0050] S3: Opening a second groove on the upper surface of the bottom layer and applying glue in the second groove;

[0051] S4: buckle the second adhesive layer into the second groove and press it into place;

[0052] S5: evenly apply adhesive to the upper surface of the second adhesive layer, and place the honeycomb layer on the upper surface of the second adhesive layer;

[0053] S6: Apply adhesive to the fixing groove on the lower surface of the surface layer, and snap the fixing block on the first adhesive layer into the fixing groove and press it to fix it;

[0054] S7: Apply glue to the lower surface of the first adhesive layer, and snap the bottom layer, the second adhesive layer, and the honeycomb layer into the first groove of the surface layer at one time, and press and place them until the glue is solidified.

[0055] Specifically, in steps s4 and s7, the pressing method may be a hydraulic method.

[0056] Compared with Example 1, Comparative Example 2 changed the interlayer material and used marble for filling and stress bearing. The overall mass and thickness increased, and the fracture strength was 3.387 MPa. It broke when the bending reached 0.35%. Although the marble filling had high strength, the structure was thicker and the toughness was insufficient, resulting in low practical application scenarios.

[0057] Comparative Example 3, compared with Example 1, uses ceramic tile material and fills the material with ceramic tile to bear the force. The thickness is low, but the quality is high. However, it breaks at a strength of 0.22 and breaks when the bending reaches 0.22%, resulting in low performance and impracticality.

[0058] Compared with Example 1, Comparative Example 4 uses cement board, which is filled with cement and has a slightly thicker thickness and slightly higher quality. It breaks at 1.429 MPa and breaks when the bending reaches 0.562%, which has better performance than Comparative Examples 2 and 3.

[0059] In this solution, honeycomb ceramic tile material is used for filling, which has the lowest thickness and the lowest quality. It breaks at 2.197Mpa and only breaks when the bending reaches 4%. Compared with other comparisons, it has the highest performance and is the best choice.

[0060] Example 2

[0061] Example 2 is basically the same as Example 1, except that the first bonding layer 4 and the second bonding layer 5 are configured as bonding coatings, the first bonding layer 4 is directly applied to the surface layer 1 to bond with the honeycomb layer 2, and the honeycomb layer 2 is directly bonded to the bottom layer 3 through the second bonding layer 5.

[0062] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
