Description

Technical Field

[0001] This utility model relates to the field of metal mesh material technology, specifically a high-strength, deformation-resistant steel wire mesh. Background Technology

[0002] Wire mesh, as a fundamental metal mesh material, is widely used in numerous fields such as mine support, building wall reinforcement, machinery protection, and agriculture. Its basic structure typically consists of multiple warp and weft wires interwoven and fixed together through weaving or welding. However, traditional wire mesh in existing technology has significant structural defects: First, the warp and weft wires generally use single-section circular wires, resulting in insufficient overall rigidity and deformation resistance due to this single-layer structure. Second, in terms of node connections, nodes formed by traditional weaving processes are prone to slippage under stress, while ordinary welded nodes suffer from stress concentration. Furthermore, the mesh edges lack effective reinforcement measures, making them susceptible to edge deformation during installation and use. When subjected to external impacts, localized pressure, or long-term uneven loads, these traditional wire meshes exhibit various failure modes, including plastic bending of the wires, loosening and detachment at node connections, localized depressions in the mesh surface, and overall torsional deformation. These deformations not only severely affect the protective performance and service life of the wire mesh but may also create safety hazards. Especially in heavy-duty applications such as mine support, the insufficient deformation resistance of traditional wire mesh can lead to support failure, and in severe cases, may cause collapse accidents. Furthermore, wire mesh also faces corrosion problems during long-term use, which further exacerbates the degradation of its structural performance. To address these issues, there is an urgent need to develop a new type of wire mesh structure with higher structural strength, better deformation resistance, and a longer service life. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a high-strength, deformation-resistant steel wire mesh, which has the advantages of improving structural strength and deformation resistance, and preventing node slippage and edge deformation.

[0004] This application provides a high-strength, deformation-resistant steel wire mesh, the technical solution of which is as follows: It includes a mesh formed by multiple warp wires and multiple weft wires interlaced, the warp wires and weft wires being a composite wire structure, the warp wires and weft wires including a main wire and at least one auxiliary wire spirally wound on the outer surface of the main wire.

[0005] Furthermore, this application also proposes that the diameter of the auxiliary steel wire is smaller than the diameter of the main steel wire.

[0006] Furthermore, this application also proposes that the intersection of the warp and weft wires be fixedly connected by welding.

[0007] Furthermore, this application also proposes that the edge of the mesh body is provided with a reinforced frame, which is made of angle steel or U-shaped steel, and the ends of the warp and weft wires are fixedly connected to the external reinforced frame.

[0008] Furthermore, this application also proposes that connecting ear plates are provided at the four corners of the reinforced frame, and mounting holes are opened on the connecting ear plates.

[0009] Furthermore, this application also proposes that the surfaces of both the main steel wire and the auxiliary steel wire are provided with a corrosion-resistant layer.

[0010] Furthermore, this application also proposes that the surfaces of both the main steel wire and the auxiliary steel wire are provided with a corrosion-resistant layer, and a wear-resistant layer is provided on the outside of the corrosion-resistant layer.

[0011] Furthermore, this application also proposes that the corrosion-resistant layer includes a phenolic resin coating and a polytetrafluoroethylene coating, and the wear-resistant layer includes a tungsten carbide coating and an alumina coating.

[0012] Furthermore, this application also proposes that a phenolic resin coating is applied to the surface of the main steel wire and the auxiliary steel wire, and a polytetrafluoroethylene coating is applied to the surface of the phenolic resin coating.

[0013] Furthermore, this application also proposes that a tungsten carbide coating is applied to the surface of a polytetrafluoroethylene coating, and an alumina coating is applied to the surface of the tungsten carbide coating.

[0014] Furthermore, this application also proposes that the phenolic resin coating and the polytetrafluoroethylene coating have the same thickness, and that the tungsten carbide coating and the alumina coating have the same thickness.

[0015] As can be seen from the above, the high-strength, deformation-resistant composite steel wire mesh and its reinforced frame assembly provided in this application effectively enhance the overall rigidity and deformation resistance of the mesh by adopting a composite steel wire structure and welded node connection method. At the same time, through edge reinforcement measures and anti-corrosion treatment, the structural stability and service life are significantly improved. It has the advantages of improving structural strength and deformation resistance, preventing node slippage and edge deformation. A wear-resistant layer is provided, which includes an alumina coating that provides the first layer of wear-resistant protection for the main steel wire and auxiliary steel wire, and a tungsten carbide coating that provides the second layer of wear-resistant protection for the main steel wire and auxiliary steel wire after the alumina coating is damaged.

[0018] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0019] Please see Figure 1-5 In existing technologies, wire mesh is widely used as a basic metal mesh material in mine support, building reinforcement, machinery protection, and agricultural and aquaculture fields. Traditional wire mesh is formed by weaving or welding single circular cross-section steel wires. This structure has defects such as insufficient overall rigidity and weak resistance to deformation. When subjected to external impact or long-term load, the mesh is prone to irreversible plastic deformation, leading to protective failure, reduced screening efficiency, and safety hazards. For example, in mine roadway support scenarios, traditional wire mesh is prone to surface indentation after being squeezed by rocks, causing the support structure to fail.

[0020] To address these issues, researchers discovered that the root cause of deformation in traditional wire mesh lies in the limited load-bearing capacity of individual wires, making it impossible to effectively distribute loads when stress is concentrated. Through repeated experiments, they found that improvements at the wire structure level, such as constructing composite wires to enhance bending resistance, can fundamentally improve the mesh's stability. Further research revealed that while maintaining the supporting strength of the main wire 101, adding auxiliary wires 102 creates a synergistic effect, enhancing structural rigidity without significantly increasing weight.

[0021] Therefore, this application proposes a mesh formed by multiple warp wires 1 and multiple weft wires 2 interlaced, wherein the warp wires 1 and weft wires 2 adopt a composite wire structure, which includes a main wire 101 and at least one auxiliary wire 102 spirally wound on the outer surface of the main wire 101.

[0022] The composite steel wire structure refers to a composite body formed by combining two or more types of steel wires. Specifically, an auxiliary steel wire 102 can be spirally wrapped around the surface of the main steel wire 101 using a cold drawing process. The main steel wire 101 serves as the load-bearing body, while the auxiliary steel wire 102 forms an outer protective layer through spiral winding. Together, they constitute a composite body with synergistic effects. The spirally wound auxiliary steel wire 102 increases the contact area between the steel wires, dispersing stress through friction when under load.

[0023] Specifically, the warp wires 1 and weft wires 2 form a mesh structure at their intersections. The main wire 101 in the composite wire structure provides basic support strength, while the auxiliary wires 102, through radial constraint generated by helical winding, suppress the deformation of the main wire 101. When the mesh is subjected to external loads, the interaction between the auxiliary wires 102 and the main wires 101 effectively prevents local bending, while the helical structure allows the wires to undergo minor deformations within their elastic range to absorb impact energy. This composite structure significantly enhances the resistance to plastic deformation of the warp and weft wires 2 while maintaining flexibility.

[0024] Compared to existing technologies, traditional wire mesh, which uses a single wire, leads to stress concentration and fails to achieve synergistic effects. In contrast, the auxiliary wire 102 in the composite wire structure complements the main wire 101 mechanically. The helical winding structure not only increases the contact friction between the wires but also restricts the radial displacement of the main wire 101 through geometric constraints. Under the same load conditions, the moment of inertia of the composite wire section is increased, thereby enhancing its bending resistance.

[0025] Through the above technical solution, this application effectively solves the problem of irreversible deformation that is common in traditional wire mesh. The composite wire structure significantly improves the overall rigidity while maintaining the flexibility of the mesh. The spirally wound auxiliary wire 102 extends the service life of the wire mesh under impact loads and long-term use environments by dispersing stress and restraining deformation, and reduces safety hazards caused by mesh deformation.

[0026] This application further proposes that the diameter of the auxiliary steel wire 102 is smaller than the diameter of the main steel wire 101.

[0027] Among them, the main steel wire 101 refers to the metal wire that serves as the core component of the composite steel wire structure. Specifically, it can be made of high-carbon steel or alloy steel and is used to provide the foundation bearing capacity.

[0028] Among them, the auxiliary steel wire 102 refers to the metal wire spirally wound around the outer periphery of the main steel wire 101. Specifically, it can be made of low carbon steel wire with higher ductility. By reducing the diameter, the spiral winding structure is made tighter, thereby reducing the stress concentration phenomenon of the composite steel wire under stress.

[0029] Specifically, when the auxiliary steel wire 102 is spirally wrapped around the surface of the main steel wire 101, its smaller diameter allows for denser contact points during winding. This structure, within the mesh formed by the interlacing of the warp and weft steel wires 1 and 2, maintains the tensile strength of the main steel wire 101 while enhancing the radial constraint of the composite steel wire through the tight winding of the auxiliary steel wire 102. When the mesh is subjected to external impact or localized load, the synergistic effect between the auxiliary steel wire 102 and the main steel wire 101 effectively disperses stress, avoiding the risk of brittle fracture caused by an excessively large diameter of a single steel wire.

[0030] Compared with existing technologies, traditional steel wire mesh, which uses a single diameter steel wire for weaving, is prone to plastic deformation at the nodes due to stress concentration. This solution, however, uses main and auxiliary steel wires with different diameters. While maintaining the load-bearing capacity of the main steel wire 101, the flexible winding of the auxiliary steel wire 102 forms a buffer layer. This allows the composite steel wire to absorb energy through the elastic deformation of the auxiliary steel wire 102 when subjected to impact, thereby reducing the probability of node breakage.

[0031] Through the above technical solution, this application can improve the stress distribution of composite steel wire, prevent node loosening and mesh surface depression, and avoid weakening the mechanical properties of main steel wire 101 due to excessive diameter of auxiliary steel wire 102, thereby extending the service life of steel wire mesh under dynamic load environment.

[0032] This application further proposes a fixed connection at the intersection of the warp wire 1 and the weft wire 2 by welding.

[0033] The interlaced node refers to the contact area formed when the warp wire 1 and the weft wire 2 intersect perpendicularly. This can be achieved using resistance welding or laser welding, where localized heating melts the metal materials to form a metallurgical bond. This feature strengthens the node connection and effectively prevents relative displacement of the wires under stress.

[0034] Welding refers to the process of melting metal materials with a heat source to form a permanent connection. This can be achieved using automated welding equipment, such as a robotic arm with a pre-set welding path to perform continuous welding operations. This feature eliminates the gaps between steel wires in traditional braiding processes by establishing a stable connection interface.

[0035] Specifically, welding is performed at each intersection of the warp wire 1 and the weft wire 2, forming a continuous metallic bond layer between the two wires in the contact area. By controlling the heat input during welding, the connection strength is ensured while preventing the mechanical properties of the wires from deteriorating due to overheating. The welded joint forms a rigid connection structure that can withstand multi-directional loads without loosening.

[0036] Compared to existing technologies, traditional wire mesh, when using a weaving process, relies solely on the friction between the wires to maintain the connection at the nodes, making it prone to slippage under dynamic loads. This solution, however, uses welding to form an irreversible metallurgical bond, significantly improving the shear resistance of the nodes while eliminating structural gaps caused by the weaving process, resulting in a more uniform stress distribution on the mesh surface.

[0037] Through the above technical solution, this application can effectively suppress the deformation of the mesh caused by node loosening, maintain the flatness of the mesh surface, avoid wire breakage caused by local stress concentration, and thus extend the service life of the wire mesh under impact load environment.

[0038] This application further proposes that the edge of the mesh body is provided with a reinforced frame, which is made of angle steel or U-shaped steel, and the ends of the warp wire 1 and the weft wire 2 are fixedly connected to the external reinforced frame.

[0039] The reinforced frame refers to the supporting structure wrapped around the edge of the mesh. It can be made of angle steel or U-shaped steel by welding or bolting, and is used to constrain the displacement of the mesh edge and distribute external loads.

[0040] Angle steel refers to metal profiles with an L-shaped cross-section, which can be formed by hot rolling. Its right-angle structure can enhance the bending resistance of the frame.

[0041] U-shaped steel refers to a metal profile with a grooved cross section. It can be made by cold bending forming process. Its U-shaped opening can wrap around the edge of the mesh and accommodate the end of the steel wire.

[0042] Among them, the fixed connection refers to forming a non-detachable connection between the end of the steel wire and the frame. This can be achieved by welding or bolt pressing, and is used to prevent relative sliding between the steel wire and the frame.

[0043] Specifically, the reinforced frame forms a continuous, closed frame structure by wrapping around the edge of the mesh. The cross-sectional shape of the angle steel or U-shaped steel provides a stable support surface. The ends of the warp wire 1 and weft wire 2 are embedded in the grooves of the frame or attached to the surface of the frame, and fixed by welding or bolting. In this way, the force on the edge of the mesh can be evenly distributed through the frame, avoiding deformation caused by local stress concentration.

[0044] Compared to existing technologies, traditional wire mesh lacks a rigid support structure at the edges, and the ends of the wires are only simply bent, making them prone to edge warping or wire detachment under impact. This solution adds a reinforced frame made of angle steel or U-shaped steel, forming an integral load-bearing structure at the mesh edges, significantly improving impact resistance and deformation resistance.

[0045] Through the above technical solutions, this application can effectively prevent the edges of the wire mesh from warping and deforming due to stress, avoid breakage or detachment of the wire ends due to stress concentration, and enhance the connection stability between the mesh and the external structure. The reinforced closed structure of the frame can also reduce the performance degradation of the mesh edges caused by corrosion or wear, and extend its service life.

[0046] This application further proposes that the four corners of the reinforced frame are provided with connecting ear plates, and the connecting ear plates are provided with mounting holes.

[0047] The connecting lug plate refers to a metal sheet component fixed to the corner of the reinforced frame. It can be fixed by welding or bolting and serves as an installation interface for connecting with other structural components. The mounting hole refers to a through-hole structure formed on the connecting lug plate. It can be made by drilling or stamping and is used to pass bolts, rivets, or retaining pins to achieve the connection.

[0048] Specifically, the four corners of the reinforced frame are fitted with connecting ear plates via welding or bolting, and mounting holes are machined into the surface of the ear plates. During the installation of the wire mesh, the mesh can be quickly positioned and fixed to the supporting structure by inserting the connecting bolts of the external fasteners into the mounting holes of the ear plates. Since the ear plates are independently set at the corners of the frame, there is no need to drill or cut the frame body during installation, thus avoiding weakening the structural strength of the frame.

[0049] Compared to existing technologies, traditional wire mesh frames typically have mounting holes directly drilled into them, leading to stress concentration and crack propagation around the holes when the frame is under stress. This solution uses independently connected ear plates to bear the installation load, maintaining the integrity of the frame structure. The stress around the mounting holes is distributed to the entire frame through the ear plates, effectively preventing localized deformation and breakage risks.

[0050] Through the above technical solution, this application solves the problem of reduced structural strength caused by opening holes in the frame during traditional wire mesh installation, achieving a balance between installation operation and frame integrity. The matching design of the connecting ear plate and the mounting hole ensures the reliability of installation and fixation, while avoiding the reduction of deformation resistance caused by processing damage to the frame body, thus extending the service life of the wire mesh under impact loads or vibration environments.

[0051] This application further proposes that the surfaces of both the main steel wire 101 and the auxiliary steel wire 102 are provided with a corrosion-resistant layer.

[0052] The corrosion-resistant layer refers to the protective material layer covering the surface of the steel wire. It can be achieved by hot-dip galvanizing or epoxy resin spraying. By forming a continuous and dense isolation layer on the surface of the steel wire, the contact between the corrosive medium and the metal substrate is blocked.

[0053] The coating process refers to the process of uniformly attaching anti-corrosion material to the outer surface of the steel wire. Specifically, it can be achieved by electrostatic spraying or immersion, ensuring that the coating completely covers the spiral contact area of ​​the main steel wire 101 and the auxiliary steel wire 102.

[0054] Specifically, after the main steel wire 101 and the auxiliary steel wire 102 are spirally wound, they enter the coating process as a whole. The anti-corrosion material is uniformly adhered to the surface of the steel wire in liquid form, and after curing, a continuous covering layer is formed. Since the gap area formed by the spiral winding of the auxiliary steel wire 102 is filled by the coating, and the contact surface between the steel wires is wrapped by the anti-corrosion material, external moisture or corrosive substances are prevented from entering the gap between the steel wires and causing electrochemical corrosion.

[0055] The surfaces of the main steel wire 101 and the auxiliary steel wire 102 are both provided with a corrosion-resistant layer 3, and a wear-resistant layer 4 is provided on the outside of the corrosion-resistant layer 3.

[0056] The corrosion-resistant layer 3 includes a phenolic resin coating 31 and a polytetrafluoroethylene coating 32, and the wear-resistant layer 4 includes a tungsten carbide coating 41 and an alumina coating 42.

[0057] A phenolic resin coating 31 is applied to the surface of the main steel wire 101 and the auxiliary steel wire 102, and a polytetrafluoroethylene coating 32 is applied to the surface of the phenolic resin coating 31.

[0058] Tungsten carbide coating 41 is applied to the surface of polytetrafluoroethylene coating 32, and aluminum oxide coating 42 is applied to the surface of tungsten carbide coating 41.

[0059] The phenolic resin coating 31 and the polytetrafluoroethylene coating 32 have the same thickness, and the tungsten carbide coating 41 and the alumina coating 42 have the same thickness.

[0060] A wear-resistant layer 4 is provided, which includes an alumina coating 42 that provides a first layer of wear-resistant protection for the main steel wire 101 and the auxiliary steel wire 102, and a tungsten carbide coating 41 that provides a second layer of wear-resistant protection for the main steel wire 101 and the auxiliary steel wire 102 after the alumina coating 42 is damaged. A corrosion-resistant layer 3 is provided, which includes a polytetrafluoroethylene coating 32 that provides a first layer of corrosion-resistant protection for the main steel wire 101 and the auxiliary steel wire 102 after the tungsten carbide coating 41 is damaged, and a phenolic resin coating 31 that provides a second layer of corrosion-resistant protection for the main steel wire 101 and the auxiliary steel wire 102 after the polytetrafluoroethylene coating 32 is damaged.

[0061] Compared to existing technologies, traditional wire mesh uses only a single wire and lacks a surface protective layer. In humid or saline environments, the wire surface is prone to oxidation, leading to a decrease in cross-sectional strength. This solution forms an anti-corrosion layer simultaneously on the surfaces of the main and auxiliary wires, protecting not only the surface of individual wires but also sealing the gaps in the composite structure formed by the spiral winding, effectively delaying the decrease in tensile strength of the wires due to corrosion.

[0062] Through the above technical solution, this application solves the problem of reduced structural strength of traditional wire mesh due to corrosion, prevents cross-sectional loss and stress concentration caused by oxidation of the wire surface, avoids mesh deformation and failure caused by localized corrosion, and thus extends the service life of wire mesh in humid, acidic and alkaline environments.

[0063] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
