Description

Method for manufacturing metal woven mesh with protruding thickness and metal woven mesh Technical Field

[0001] The present invention relates to a method for manufacturing a metal woven mesh with a protruding thickness and the metal woven mesh, and in particular to a method for manufacturing a metal woven mesh capable of increasing the thickness of spraying to enhance the strength of a structure and the metal woven mesh. Background Art

[0002] In order to prevent hillside walls and side slopes from sliding and collapsing, and to enhance the strength of cement structures on special terrains, roads, and bridges, a layer of metal woven mesh is usually laid on the structure and then cement slurry is sprayed on it to form a structure that has sufficient strength to prevent the hillside or side slope from sliding, collapsing, or breaking.

[0003] For example, in structures on hillside walls or side slopes, a metal mesh woven with metal wires is attached to the hillside or side slope, and cement slurry is sprayed on the metal mesh. However, since the metal mesh is only relatively thin and directly attached to the hillside or side slope, the sprayed cement slurry cannot have a sufficient thickness, resulting in insufficient strength of the structure, which may still crack or collapse.

[0004] Furthermore, for example, in cement-constructed ground structures such as roads and bridges, a metal mesh woven with metal wires is attached to the ground plane. Pads are then placed between the metal mesh and the ground to raise the metal mesh to create a larger gap between the mesh and the ground. This allows cement slurry to fully fill the gaps between the mesh and the ground. While this can increase the strength of the structure, placing the pads requires significant labor during construction, and a large number of pads can also reduce the strength of the structure.

[0005] Please refer to FIG. 1 , which shows a “metal braided mesh” disclosed in Japanese Patent Laid-Open No. 2009-30261. The metal braided mesh is mainly composed of a metal wire bent into straight rods 91 of a certain length and mountain-shaped bent rods 92. The straight rods 91 are arranged in parallel at equal intervals. The mountain-shaped bent rods 92 are connected to one end in one direction and one end in the other direction of each straight rod 91 to form a connecting bent portion 93. The mountain-shaped portion in the middle protrudes on one side to form the metal braided mesh 9.

[0006] Referring to FIG. 2 , the aforementioned metal braided mesh 9 is formed using a conventional diamond mesh manufacturing method. Specifically, a metal wire P is wound around a mold M. The mold M continuously rotates and pushes the wire P to form metal lines P1 of a predetermined length, each having straight rods 91 and mountain-shaped curved rods 92. These metal lines P1 are then threaded through the metal braided mesh 9, which is also manufactured using the same method. Because the metal wire P must be wound around the mold M during the manufacturing process, the metal braided mesh 9 can only be manufactured using metal wire P of a small diameter. Furthermore, adjacent metal lines P1 forming the metal braided mesh 9 are connected only by connecting curved portions 93. Consequently, the metal braided mesh 9 is insufficiently strong and cannot withstand significant pressure. If even one of the metal lines P1 breaks, the entire metal braided mesh 9 suffers extensive damage.

[0007] In view of this, the existing metal woven mesh structure really needs to be improved.

[0008] Summary of the Invention

[0009] In order to solve the above problems, the purpose of the present invention is to provide a method for manufacturing a metal woven mesh with a protruding thickness, which can manufacture protrusions protruding from the metal woven mesh, so that the metal woven mesh has a greater thickness.

[0010] Another object of the present invention is to provide a metal woven mesh with a protruding thickness, which can enhance the strength of a structure.

[0011] The directions or their approximate terms described throughout the present invention, such as "front", "back", "left", "right", "upper (top)", "lower (bottom)", "inside", "outside", "side", etc., mainly refer to the directions of the accompanying drawings. Each direction or its approximate terms are only used to assist in explaining and understanding the various embodiments of the present invention, and are not used to limit the present invention.

[0012] The quantifiers “a” or “an” used in the elements and components described throughout the present invention are only for convenience and to provide a general meaning of the scope of the present invention; they should be interpreted in the present invention as including one or at least one, and the single concept also includes the plural case, unless it is obvious that it means otherwise.

[0013] The present invention provides a method for manufacturing a metal braided mesh having a protruding thickness, comprising: forming a plurality of wires into a plurality of groups of two adjacent wires; performing a winding step to wind each of the two adjacent wires a predetermined number of turns to form a winding portion; performing a displacement step to relatively displace each of the two adjacent wires wound the predetermined number of turns a predetermined distance so that each of the wires forms an oblique line segment extending from one end of the winding portion, thereby forming a plurality of groups of two adjacent wires; repeating the winding step and the displacement step to form a metal braided mesh having a hexagonal grid shape of a predetermined size by the plurality of wires; and forming a plurality of bends on the plurality of wires on the metal braided mesh so that the plurality of bends protrude toward the upper surface or / and the lower surface of the metal braided mesh.

[0014] The metal braided mesh of the present invention comprises: a plurality of wires arranged in a staggered manner to form a plurality of winding portions, the metal braided mesh having an upper surface and a lower surface relative to each other; and a plurality of bending portions formed on the wires, the bending portions protruding toward the upper surface and / or the lower surface of the metal braided mesh.

[0015] Therefore, the method for manufacturing a metal woven mesh with a protruding thickness of the present invention continuously repeats the winding step to produce the metal woven mesh, so that the mesh of the metal woven mesh has the winding portion, thereby improving the structural strength of the metal woven mesh itself. The bending step also provides the protruding bending portion on the upper surface and / or lower surface of the metal woven mesh, thereby producing a metal woven mesh with a protruding thickness. The provision of the bending portion allows the metal woven mesh to have a greater distance from a surface such as a hillside, a slope, a road, or a bridge. In this way, when cement slurry is sprayed on the metal woven mesh, the cement slurry accumulates above and below the wires. In this way, the cement slurry can form a greater thickness, thereby improving the strength of the structure and reducing the manpower required to lay the pads during construction, thereby reducing construction costs.

[0016] The bent portion is directly formed on the wire material by stamping and / or bending, which facilitates the processing and forming of the bent portion.

[0017] The bent portion is formed between any two adjacent winding portions, so that the bent portion can be easily processed and formed.

[0018] The bending portion is formed on the winding portion, so that when the bending portion abuts against a plane, it has better strength to support the metal braided mesh. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the above and other objects, features and advantages of the present invention more obvious and easy to understand, the preferred embodiments of the present invention are specifically cited below and described in detail with reference to the accompanying drawings. In addition, the same symbols in different drawings are regarded as the same and their descriptions are omitted.

[0032] Please refer to Figures 3 and 4, which show a preferred embodiment of the method for manufacturing a metal braided mesh with a protruding thickness according to the present invention, comprising an arranging step S1, a winding step S2, a displacement step S3, a repeating step S4, and a bending step S5. The arranging step S1 is to form a plurality of wires 1 into a plurality of groups of two adjacent wires 1. The winding step S2 is to respectively wind the two adjacent wires 1 a predetermined number of turns. The displacement step S3 is to relatively displace the two adjacent wires 1 wound the predetermined number of turns by a predetermined distance. The repeating step S4 is to repeat the winding step S2 and the displacement step S3 to form the plurality of wires 1 into a metal braided mesh with a hexagonal grid of a predetermined size. The bending step S5 is to form the metal braided mesh into at least one bent portion 2.

[0033] Continuing with FIG4 , specifically, the method for manufacturing a metal braided mesh having a protruding thickness can be operated, for example, by a braiding machine T, thereby reducing labor costs and improving operational efficiency through automated operations. Furthermore, a free end of each wire 1 can be secured to a traction member L, and each wire 1 can be secured to the traction member L by tying, winding, or hooking. The traction member L can be a reel and can be driven, for example, by a motor to continuously reel in a direction. Thus, the traction member L can drive the metal braided mesh formed by the multiple wires 1 to be reeled onto the surface of the traction member L.

[0034] The user can adjust the number of the wires 1 to form a metal braided mesh of a predetermined size, and the present invention is not limited thereto. In this embodiment, four wires 1a, 1b, 1c, and 1d are used as an example for illustration. In the arrangement step S1, the wires 1a, 1b, 1c, and 1d can be clamped and positioned by the four clamps T1, T2, T3, and T4 of the braiding machine T, respectively, wherein two of the clamps T1 and T2 are adjacent to each other so that the two wires 1a and 1b are adjacent to each other, and two of the clamps T3 and T4 are adjacent to each other so that the two wires 1c and 1d are adjacent to each other.

[0035] In the winding step S2, the two clamps T1 and T2 rotate about an axis O1, and the axis O1 is located between the two adjacent clamps T1 and T2, so that the two wires 1a and 1b are wound, and the two clamps T3 and T4 rotate about an axis O2, and the axis O2 is located between the two adjacent clamps T3 and T4, so that the two wires 1c and 1d are wound. The number of winding turns of the two clamps T1 and T2 and the two clamps T3 and T4 can be 3 to 4 turns, so that the two wires 1a and 1b and the two wires 1c and 1d respectively form a winding portion 11. In this way, by winding each wire 1 to form the winding portion 11, the stability of the connection between each wire 1 can be improved. In addition, in the winding step S2, the pulling member L can be rolled at the same time so that each wire 1 can be pushed and wound smoothly.

[0036] Please refer to Figure 5, in the displacement step S3, the two clamps T1 and T2 are respectively displaced in opposite directions (i.e., respectively displaced to the left and to the right) a predetermined distance and separated. At this time, the two adjacent wires 1a and 1b are stretched and separated to form an oblique line segment extending from one end of the winding portion 11 toward the lower left and lower right directions. Similarly, the two clamps T3 and T4 are respectively displaced in opposite directions by the predetermined distance and separated. At this time, the two adjacent wires 1c and 1d are separated to form an oblique line segment extending from one end of the winding portion 11 toward the lower left and lower right directions. It is worth noting that the clamp T2 displaced to the right will form abutment with the clamp T3 displaced to the left, thereby driving the two wires 1b and 1c to form abutment. In addition, the wire 1a and the wire 1d are respectively driven by the two clamping members T1 and T4 to form an adjacent connection with the adjacent wire on the other side. This is well known to those skilled in the art and will not be elaborated here.

[0037] In the repetitive step S4, the winding step S2 and the displacement step S3 can be repeated. That is, when the winding step S2 is repeated, the adjacent clamps T2 and T3 are rotated about an axis O3, and the axis O3 is located between the two adjacent clamps T2 and T3, so that the two wires 1b and 1c are wound to form the winding portion 11. At the same time, the wire 1a and the wire 1d are respectively driven by the two clamps T1 and T4 to form a winding with the wire adjacent to the other side. When the displacement step S3 is continuously repeated, the two clamps T2 and T3 are respectively displaced in opposite directions (i.e., to the left and to the right, respectively) by a predetermined distance and separated. At this time, the two adjacent wires 1b and 1c are stretched and separated to form an oblique line segment 12 extending from one end of the winding portion 11 to the lower left and lower right directions.

[0038] Similarly, after the clamping member T1 drives the wire 1a to be wound with the wire adjacent to the other side, it is displaced again to be adjacent to the clamping member T2, and after the clamping member T4 drives the wire 1c to be wound with the wire adjacent to the other side, it is displaced again to be adjacent to the clamping member T3. In this way, the clamping members T1, T2, T3, and T4 can be restored to the arrangement form in which the clamping members T1 and T2 are adjacent, and the clamping members T3 and T4 are adjacent. Accordingly, the winding step S2 and the displacement step S3 are continuously repeated a predetermined number of times, so that the multiple wires 1 form a hexagonal grid-shaped metal woven mesh of a predetermined size. It is worth noting that in the hexagonal grid-shaped metal woven mesh, at least two pairs of sides of each grid can form the winding portion 11, which can strengthen the structure of the metal woven mesh. Even if one side of the hexagonal grid is broken due to pulling or wear, the structural integrity of the metal woven mesh can be maintained.

[0039] In the bending step S5 , the bent portion 2 can be directly formed on the plurality of wires 1 by die stamping or bending, so that the bent portion 2 can protrude toward the upper surface and / or lower surface of the metal braided mesh.

[0040] 6 and 7 , the method for manufacturing a metal braided mesh with a projecting thickness of the present invention can produce a metal braided mesh composed of a plurality of wires 1 . The metal braided mesh has an upper surface and a lower surface opposite to each other, and the plurality of wires 1 have a plurality of winding portions 11 , and at least one wire 1 has at least one bending portion 2 .

[0041] The bent portion 2 may protrude toward the upper surface and / or lower surface of the metal woven mesh, and the bent portion 2 may abut a plane P, thereby creating a greater distance between the metal woven mesh and the plane P. The bent portion 2 may protrude regularly or irregularly, and may be formed between any two adjacent winding portions 11, or may be formed within the winding portion 11, without limitation in the present invention. In this embodiment, the bent portion 2 protrudes regularly from the lower surface of the metal woven mesh, and the bent portion 2 is formed between any two adjacent winding portions 11.

[0042] Referring to FIG. 7 , when the metal mesh is laid on a plane P such as a hillside, a slope, a road, or a bridge, the metal mesh has the bent portion 2 , which creates a greater distance between the metal mesh and the plane P. Thus, when cement slurry is sprayed on the metal mesh formed by the wires 1 , the cement slurry can accumulate not only above the wires 1 but also below the wires 1 . This allows the cement slurry to form a greater thickness, thereby increasing the strength of the structure and reducing the manpower required to lay the pads during construction, thereby lowering construction costs.

[0043] Please refer to Figures 8 and 9, which are a second embodiment of the metal braided mesh of the present invention. This embodiment is substantially the same as the first embodiment. In this embodiment, the wire 1 has a plurality of bent portions 2. In this embodiment, the bent portions 2 protrude at intervals from the lower surface of the metal braided mesh, and the bent portions 2 are formed on the winding portion 11.

[0044] Please refer to Figures 10 and 11, which are a third embodiment of the metal woven mesh of the present invention. This embodiment is substantially the same as the second embodiment. In this embodiment, the bent portions 2 protrude at intervals on the upper and lower surfaces of the metal woven mesh, and the bent portions 2 are formed on the winding portion 11. In this way, when pouring cement slurry, the cement slurry can form a greater thickness to enhance the strength of the structure.

[0045] In summary, the method for manufacturing a metal woven mesh with a protruding thickness of the present invention continuously repeats the winding step to produce the metal woven mesh, so that the mesh of the metal woven mesh has the winding portion, thereby improving the structural strength of the metal woven mesh itself. The bending step also provides the upper surface and / or lower surface of the metal woven mesh with the protruding bending portion, thereby producing a metal woven mesh with a protruding thickness. In this way, the metal woven mesh has a larger distance from a surface such as a hillside, a side slope, a road, or a bridge due to the provision of the bending portion. In this way, when cement slurry is sprayed on the metal woven mesh, the cement slurry accumulates above and below the wire. In this way, the cement slurry can form a larger thickness to improve the strength of the structure, and can reduce the manpower required to lay the pads during construction, thereby reducing construction costs.

[0046] Although the present invention has been disclosed using the above-mentioned preferred embodiments, they are not intended to limit the present invention. Any person skilled in the art may make various changes and modifications to the above-mentioned embodiments without departing from the spirit and scope of the present invention, and these changes and modifications are still within the technical scope protected by the present invention. Therefore, the scope of protection of the present invention shall include the contents described in the attached patent application scope and all changes within the scope of equivalents.
