AI Technical Summary
There is a contradiction between the strength performance and the filtration and interception performance of existing wire mesh. Coarse diameter wire has high strength but low screening accuracy, while fine diameter wire has weak structural strength but good interception performance, making it difficult to meet the requirements of high-load conditions and precision filtration at the same time.
The composite sandwich mesh structure is adopted, which constructs the mesh frame by first warp and weft ribs with a large diameter, and combines it with the clamping chip with a small diameter to form a double fixing structure by welding or metallurgy. The clamping chip uses fine wire to form a precision filter layer to achieve high tensile strength and precision screening.
Sandwich mesh possesses both high resistance to deformation and precision screening capabilities, enabling it to withstand high-load conditions and improving its performance in fields such as construction and chemical engineering.

Description
Technical Field
[0001] This utility model relates to the field of wire mesh technology, and in particular to a composite sandwich mesh. Background Technology
[0002] Wire mesh is widely used in construction, agriculture, industry, transportation, water conservancy, chemical industry and other fields for protection, isolation, interception, filtration and screening.
[0003] Existing technologies present the following contradictions: while using coarse-diameter wire to make wire mesh provides strong structural support and resistance to deformation and breakage, the larger mesh size leads to decreased filtration and sieving accuracy, and insufficient material isolation and interception capabilities. Conversely, using fine-diameter wire significantly improves filtration, interception performance, and sieving accuracy, but the reduced material cross-section results in a decrease in overall structural strength, making it difficult to withstand the mechanical loads under actual working conditions. This technical bottleneck, where strength performance and filtration / interception performance are at odds, has become a significant obstacle restricting the development of wire mesh in related fields.
[0004] Therefore, those skilled in the art urgently need to break through the traditional wire mesh design and develop a new structure that has both high resistance to deformation and precision screening function in order to solve the long-standing performance contradiction problem. Utility Model Content
[0005] In view of the shortcomings of the prior art, this utility model provides a composite sandwich mesh to solve the problems in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] This utility model provides a composite sandwich mesh, comprising:
[0008] The mesh includes multiple first warp and first weft bars, which are welded together at their intersections to form weld points, and adjacent first warp and first weft bars together form a first mesh.
[0009] The clip is held and fixed between the first warp and the first weft, with the first warp attached to the front side of the clip and the first weft attached to the rear side of the clip.
[0010] In one possible implementation, the mesh is made of a metallic material.
[0011] In one possible implementation, when the clip chip is made of a metallic conductive material, the clip chip is fixedly connected to the first warp and the first weft at the solder joint.
[0012] In one possible implementation, during the welding process, the conductive clip chip forms a conductive connection with the first warp and the first weft at their intersection, thereby allowing the clip chip to be simultaneously welded to the weld point.
[0013] In one possible implementation, when the clip chip is made of a non-metallic conductive material, the clip chip is provided with a clearance hole located at the solder joint where the first warp rib and the first weft rib intersect.
[0014] In one possible implementation, the material of the clip chip includes cloth, plastic, fiber, or paper.
[0015] In one possible implementation, the clip chip is a mesh structure woven from intersecting second warp and second weft ribs. There are multiple second warp and second weft ribs, and both are conductive. Two adjacent second warp and second weft ribs enclose each other to form a second mesh. The diameter of the second mesh is smaller than that of the first mesh.
[0016] In one possible implementation, the diameter of the second warp bar is smaller than that of the first warp bar; the diameter of the second weft bar is smaller than that of the first weft bar.
[0017] The diameter of the second warp bar is smaller than the diameter of the first weft bar; the diameter of the second weft bar is smaller than the diameter of the first warp bar.
[0018] In one possible implementation, the clip chip is a mesh structure formed by stamping a metal sheet, and the clip chip has a plurality of stamped holes, the diameter of which is smaller than the diameter of the first mesh hole. Beneficial effects
[0019] This utility model provides a composite sandwich mesh, which includes a mesh sheet and a clamping chip sandwiched in the middle of the mesh sheet. The clamping chip is held and fixed between the first warp and the first weft. The first warp is attached to the front side of the clamping chip, and the first weft is attached to the rear side of the clamping chip. The sandwich mesh uses the first warp and the first weft of the mesh sheet, made of coarse-diameter wire, to construct the mesh frame. Utilizing its high tensile strength, the overall structure of the sandwich mesh can withstand external impacts, meeting the requirements of high-load conditions such as building protection and chemical screening. Simultaneously, the clamping chip uses the second warp and the second weft of fine-diameter wire to form a filtering, intercepting, and screening capability. The aperture of the second mesh is smaller than that of the first mesh, achieving efficient interception, thus solving the technical problem of traditional wire mesh being "strong but sparse with coarse wire and weak with fine wire."
[0020] This utility model provides a composite sandwich mesh, in which the mesh is welded together by the first warp and the first weft through a welding process. When the core material is a conductive metal, the heat effect of the welding process is used to simultaneously achieve the metallurgical bonding of the core mesh and the base mesh at the welding point, forming a dual fixing structure of "mechanical clamping + metallurgical fusion".
[0021] This utility model provides a composite sandwich mesh. When the sandwich mesh is made of non-metallic conductive material, the first warp and first weft of the mesh can be welded and fixed by opening avoidance holes, thus ensuring the main structural strength of the sandwich mesh.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. In addition, for the sake of convenience, the terms "upper," "lower," "left," and "right" are equivalent to the upper, lower, left, and right directions of the accompanying drawings themselves, and the terms "first," "second," etc., are used for descriptive purposes and have no other special meaning.
[0035] To address the shortcomings of existing technologies, this utility model provides a composite sandwich mesh, which includes mesh sheets and interlocking chips sandwiched between the mesh sheets, as detailed below:
[0036] The mesh is made of metal and includes multiple first warp and first weft bars. The first warp and first weft bars are welded together at their intersections to form weld points, and two adjacent first warp and first weft bars enclose each other to form a first mesh.
[0037] In specific applications, the mesh is welded together at the intersection of multiple first warp and first weft ribs to form a strong weld point, thus constructing a stable mesh frame and providing a solid foundation for the sandwich mesh. Its design using thick-diameter wire gives the mesh high tensile strength and excellent structural support performance, enabling the overall structure of the sandwich mesh to withstand greater external impacts and meet the needs of high-load working conditions such as construction and chemical industries.
[0038] Meanwhile, the welding process enhances the overall stability of the mesh, ensuring that the sandwich mesh is not easily deformed or damaged during use, thereby extending its service life. Furthermore, as the main structure of the sandwich mesh, the mesh provides stable support for the sandwiched chips, ensuring the full utilization of the chip isolation, filtration, and screening functions, thus improving the overall interception, filtration performance, and accuracy of the sandwich mesh.
[0039] Furthermore, both the first warp and the first weft are galvanized iron wires of the same diameter. The first warp and the first weft can be made of metal wire or other conductive metal materials. Under the premise of ensuring that the working performance of the mesh is not affected, those skilled in the art can select the materials of the first warp and the first weft according to actual needs. The change of the materials of the first warp and the first weft does not affect the scope of protection of this application.
[0040] Furthermore, the shape of the first mesh can be rectangular, square, rhomboid, or other regular shapes.
[0041] The chip is clamped and fixed between the first warp rib and the first weft rib. The first warp rib is attached to the front side of the chip clamp, and the first weft rib is attached to the rear side of the chip clamp.
[0042] In specific applications, the clips are securely held between the first warp and first weft ribs of the mesh, ensuring their stability within the mesh and preventing displacement or detachment during use. This, in turn, guarantees the overall structural stability of the sandwich mesh. Simultaneously, because the clips are fixed inside the mesh, the second mesh, composed of fine-diameter wires, can more effectively intercept particles, improving screening accuracy and meeting the requirements of precision filtration and interception.
[0043] In addition, by combining the mesh sheet and the sandwich chip, the technical contradiction of traditional wire mesh being "strong but sparse with coarse wire and weak with fine wire" has been successfully solved. The mesh sheet provides structural support, while the sandwich chip enables precision filtration and interception. The two complement each other, so that the sandwich mesh has both high resistance to deformation and precision screening and interception functions.
[0044] The mesh is constructed using thick-diameter wire to form the mesh frame. Utilizing its high tensile strength, the overall structure of the sandwich mesh can withstand significant external impacts, meeting the needs of high-load working conditions such as construction and chemical industries, and improving its applicability and reliability.
[0045] In the construction field, specifically during the construction of composite steel mesh houses, the metal mesh frame, composed of sandwich mesh, serves as a crucial component of the wall structure and is placed on the outside of the concrete pouring layer. During concrete pouring, the metal mesh frame effectively intercepts concrete slurry, preventing it from flowing out of the wall. It can replace traditional formwork, providing support and shaping for the concrete.
[0046] In some examples, when the clip is made of a conductive metallic material, the clip is fixedly connected to the first warp and first weft at the solder joints, ensuring a firm bond between the clip and the mesh, preventing the clip from shifting or falling off during use, thereby ensuring the overall structural stability of the sandwich mesh.
[0047] In some examples, during the welding process, the conductive clip chip forms a conductive connection with the first warp and first weft ribs at their intersection, thereby allowing the clip chip to be welded synchronously at the weld point. Through the fixed connection at the weld point, the combination between the clip chip and the mesh is tighter, which significantly enhances the structural strength of the entire composite sandwich mesh, improves its resistance to deformation and load-bearing capacity, and enables the sandwich mesh to better withstand external impacts.
[0048] In specific application scenarios, the sandwich chip and the mesh not only form a mechanical clamp, but when the sandwich chip is a conductive metal material, a metallurgical bond is achieved at the weld point through a welding process, forming a dual fixing structure of "mechanical clamping + metallurgical fusion", which significantly enhances the overall strength of the sandwich mesh and improves its resistance to deformation and load-bearing capacity.
[0049] In some examples, when the clip chip is made of a non-metallic conductive material, a clearance hole is provided on the clip chip, and the clearance hole is located at the solder joint where the first warp rib and the first weft rib intersect.
[0050] Furthermore, the clearance hole is used to avoid the weld point, so that the first warp rib and the first weft rib can form a conductive connection.
[0051] In specific applications, the use of clearance holes provides an effective solution to the problem that non-metallic conductive material clips cannot be directly involved in soldering. It ensures a reliable connection between the clipped chip and the mesh, allowing the non-metallic clipped chip to be securely held within the mesh, preventing displacement or detachment.
[0052] At the same time, it will not affect the conductive connection formed at the intersection of the first warp and the first weft of the mesh, which allows the mesh to form stable weld points through the welding process, thereby maintaining its structural strength and providing solid support for the sandwich mesh.
[0053] In some examples, the materials used to clip the chip include cloth, plastic, fiber, or paper.
[0054] In specific application scenarios, the chip clamp can be made of cloth, plastic, fiber, paper, or other non-conductive materials. As long as the working performance of the chip clamp is not affected, those skilled in the art can choose the chip clamp material according to actual needs. Changes in the chip clamp material do not affect the scope of protection of this application.
[0055] In some examples, the clip chip is a mesh structure woven from intersecting second weft ribs and second warp ribs. There are multiple second warp ribs and second weft ribs, and both are conductive. The second mesh is formed by two adjacent second warp ribs and second weft ribs. The aperture of the second mesh is smaller than that of the first mesh, which enables the clip chip to efficiently intercept small particles or materials, significantly improves the screening accuracy, and meets the needs of precision filtration.
[0056] In specific application scenarios, the sandwich chip uses fine-diameter wires to form a precision filter layer. The second mesh aperture is smaller than the first mesh aperture of the mesh, which enables the sandwich mesh to achieve efficient interception and precision filtration while maintaining high structural strength, meeting the application scenarios with strict requirements for particle size.
[0057] In some examples, the diameter of the second warp rib is smaller than that of the first warp rib; the diameter of the second weft rib is smaller than that of the first weft rib; the diameter of the second warp rib is smaller than that of the first weft rib; and the diameter of the second weft rib is smaller than that of the first warp rib. This allows the clip-on chip to intercept even smaller particles or microparticles, thereby significantly improving filtration accuracy and screening effect.
[0058] In specific applications, it breaks through the technical bottleneck of traditional wire mesh, which is characterized by "strong but sparse coarse wires and delicate but weak fine wires." By combining the advantages of both coarse and fine wires, it achieves the dual functions of high strength and precision filtration, thus improving the overall performance of the sandwich mesh.
[0059] In some examples, the clip chip is a mesh structure formed by stamping a metal sheet, and the clip chip has several stamped holes, the diameter of which is smaller than the diameter of the first mesh hole. Example 1

[0064] In the example, when the clip chip 2 is made of a metallic conductive material, the clip chip 2 is fixedly connected to the first warp rib 11 and the first weft rib 12 at the solder joint.
[0065] In the example, during the welding process, the conductive clip 2 will form a conductive connection with the first warp rib 11 and the first weft rib 12 at the intersection, so that the clip 2 is synchronously welded to the solder joint.
[0066] In the example, such as Figure 2As shown, the clip chip 2 is a mesh structure woven from intersecting second warp ribs 21 and second weft ribs 22. Both the second warp ribs 21 and the second weft ribs 22 are multiple and conductive. Figure 3 , Figure 3 As shown, the second warp ribs 21 and the second weft ribs 22, which are adjacent to each other, form a second mesh. The diameter of the second mesh is smaller than that of the first mesh.
[0067] In the example, such as Figure 2 As shown, the diameter of the second warp rib 21 is smaller than that of the first warp rib 11; the diameter of the second weft rib 22 is smaller than that of the first weft rib 12.
[0068] like Figure 2 As shown, the diameter of the second warp rib 21 is smaller than the diameter of the first weft rib 12; the diameter of the second weft rib 22 is smaller than the diameter of the first warp rib 11. Example 2
