Description

Technical Field

[0001] This utility model relates to the field of wall-mounted mesh technology, specifically, to a wall-mounted mesh. Background Technology

[0002] External wall insulation materials play a crucial role in modern buildings, primarily improving energy efficiency and reducing heat loss, thereby lowering energy consumption. In external wall insulation systems, wire mesh is a key material, typically used to enhance the structural strength and stability of the insulation material. Common types of wire mesh used in external wall insulation include fiberglass mesh, plastic mesh, and metal mesh. These meshes are usually embedded in the plaster layer to increase its tensile strength and crack resistance.

[0003] Fiberglass mesh is widely used in exterior wall insulation systems due to its good tensile strength and alkali resistance. It effectively disperses stress and prevents plaster layer cracking. Plastic mesh, on the other hand, is used in insulation systems for some lightweight walls and partition walls due to its lightweight and easy-to-install characteristics. Metal mesh, especially steel wire mesh, is often used in exterior wall insulation systems requiring additional reinforcement due to its high strength and durability.

[0004] However, while existing wire mesh can enhance the overall performance of external wall insulation systems to some extent, it still faces some technical challenges during long-term use. Over time and with changes in external temperature, the insulation material shrinks and deforms. This shrinkage stress is difficult to effectively counteract in existing wire mesh structures, leading to cracks in the exterior wall plaster layer and even large-scale peeling. This not only affects the aesthetics of the building but, more seriously, reduces the efficiency and safety of the insulation system. Utility Model Content

[0005] This utility model proposes a wall-mounted mesh that solves the problem in related technologies where the mesh structure is difficult to effectively offset the shrinkage stress of the insulation material, leading to cracks in the exterior wall plaster layer or even large-area detachment, which reduces the efficiency and safety of the insulation system.

[0006] The technical solution of this utility model is as follows:

[0007] A wall-mounted mesh includes a grid, the grid comprising a plurality of horizontal bars and a plurality of vertical bars, the horizontal bars and vertical bars being fixedly intersected by each other, and each intersection of the horizontal bars and vertical bars being fixedly connected with a needle, the needles extending away from the grid.

[0008] Furthermore, the grid is provided with several fixing structures for further fixing the grid. The fixing structure includes a fixing member and a fixing nail. The fixing nail is embedded in the fixing member for fixing. One end of the fixing member abuts against the grid. The fixing member is provided with several fixing slots. The fixing nail is provided with several elastic plates. The elastic plates extend through the fixing slots to the outside of the fixing member.

[0009] Furthermore, the fixing member includes a top plate and a first fixing rod. One end of the first fixing rod is fixedly connected to the middle of the top plate. The first fixing rod extends away from the top plate and has a hollow structure. The fixing slots are located on the first fixing rod, and a plurality of the fixing slots are arranged circumferentially around the first fixing rod. The first fixing rod has a first annular protrusion inside, which is fixedly connected to the inner wall of the first fixing rod. The top plate has a cross groove on the side away from the first fixing rod.

[0010] Further, the fixing pin includes a cross plate and a second fixing rod. One end of the second fixing rod is fixedly connected to the middle of the cross plate. The second fixing rod extends away from the cross plate. The elastic plate is located on the second fixing plate. The second fixing plate is fixedly connected to two second annular protrusions. The second annular protrusions are located on the side of the elastic plate away from the cross plate. A first gap is provided between the second annular protrusion closest to the elastic plate and the elastic plate. A second gap is provided between the two second annular protrusions. The first annular protrusion is embedded in the first gap. The first gap and the second gap have the same height. The width of the first gap is the same as the height of the cross groove. The cross plate is embedded in the cross groove. The distance between the first gap and the cross plate is the same as the distance between the first annular protrusion and the cross groove.

[0011] Furthermore, a limiting strip is fixedly connected to the inner wall of the first fixing rod, the limiting strip is parallel to the first fixing rod, and a limiting groove is provided on the outer wall of the second fixing rod, the limiting strip and the limiting groove are positioned correspondingly, and the cross-section of the limiting strip and the cross-section of the limiting groove are the same.

[0012] Furthermore, the edge of the top plate is provided with several auxiliary protrusions, which extend away from the top plate and extend in the same direction as the first fixing rod.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] This invention utilizes a grid structure formed by the intersecting and fixing of horizontal and vertical bars to provide uniform mechanical support. The intersecting fixing of the horizontal and vertical bars not only improves the overall strength of the mesh but also enhances its support for the external wall plaster layer. This structure helps to evenly distribute the shrinkage stress of the insulation material caused by temperature changes, preventing stress concentration at a single point or along a single line, thereby reducing the risk of plaster layer cracking. The needle-punching technique firmly embeds the mesh into the insulation material and plaster layer, acting as an anchor. Needling effectively increases the bonding force between the plaster layer and the mesh, further preventing plaster layer detachment. Needling disperses stress in the horizontal and vertical directions and provides additional fixing force in the vertical direction, helping to counteract the stress caused by the shrinkage of the insulation material. The fixing structure provides more fixing points, making the bond between the mesh and the wall and insulation material more secure. Through multi-point fixing, the fixing structure effectively prevents local loosening and stress concentration, further reducing the possibility of plaster layer cracking and detachment. This invention solves the problem in related technologies that the mesh structure is difficult to effectively offset the shrinkage stress of the insulation material, which leads to cracks in the plaster layer of the exterior wall or even large-area peeling, reducing the efficiency and safety of the insulation system.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1

[0026] like Figure 1 As shown in Example 1, a wall-mounted mesh is proposed, comprising a mesh 1, which includes several horizontal bars 11 and several vertical bars 12. The horizontal bars 11 and vertical bars 12 are intersected and fixed together. At each intersection of the horizontal bars 11 and vertical bars 12, a needle 2 is fixedly connected, extending away from the mesh 1. The mesh 1 gives the entire wall-mounted mesh high tensile and compressive strength, effectively supporting the external wall insulation material. The needles 2 are embedded in the insulation material and plaster layer, increasing the bonding force between the mesh 1 and the insulation material and plaster layer, preventing the plaster layer from detaching. The needles 2 provide vertical fixing force, preventing interlayer slippage of the insulation material and plaster layer under external stress, improving the stability of the system. The needles 2 disperse and offset stress in multiple directions, reducing the risk of plaster layer cracking due to insulation material shrinkage.

[0027] Example 2

[0028] like Figures 2-7As shown, the difference between Embodiment 2 and Embodiment 1 is that the mesh 1 is provided with several fixing structures 3 for further fixing the mesh 1. The fixing structure 3 includes fixing members 31 and fixing nails 32. The fixing nails 32 are embedded in the fixing members 31 for fixation. One end of the fixing member 31 abuts against the mesh 1. The fixing member 31 is provided with several fixing slots 314, and the fixing nails 32 are provided with several elastic plates 323. The elastic plates 323 extend through the fixing slots 314 to the outside of the fixing member 31. The fixing structure 3 provides additional fixing points, allowing the mesh to adhere more firmly to the wall, further improving the stability of the system. The multi-point support combined with the fixing structure 3 and the pins 2 reduces the possibility of local loosening and stress concentration, ensuring the stability of the insulation material and plaster layer during long-term use, and reducing the possibility of cracking and peeling of the plaster layer. The fixing members 31 are used to embed into the insulation material and into the wall connected to the insulation material. The fixing nails 32 are used to fix the connection between the fixing members 31 and the wall or insulation material. The fixing slot 314 is used to allow the elastic plate 323 to pass through, thereby positioning one end of the elastic plate 323 outside the fixing member 31. The elastic plate 323 is used to embed into the wall or insulation material to fix the fixing member 31. The elastic plate 323 can provide a certain elastic fixing force, effectively absorbing and buffering the shrinkage stress of the insulation material caused by temperature changes, reducing the risk of cracking of the plaster layer. The design of the elastic plate 323 increases the seismic performance of the fixing system, maintaining the stability of the mesh and preventing it from falling off in the event of an earthquake or other vibration.

[0029] In embodiment 2, the fastener 31 includes a top plate 311 and a first fixing rod 312. One end of the first fixing rod 312 is fixedly connected to the middle of the top plate 311. The first fixing rod 312 extends away from the top plate 311 and has a hollow structure. Fixing slots 314 are located on the first fixing rod 312, and several fixing slots 314 are arranged circumferentially around the first fixing rod 312. A first annular protrusion 315 is provided inside the first fixing rod 312, and the first annular protrusion 315 is fixedly connected to the inner wall of the first fixing rod 312. A cross groove 319 is provided on the side of the top plate 311 opposite to the first fixing rod 312. The top plate 311 provides a wide contact surface to make close contact with the grid 1 and the wall, enhancing the fixing force. The first fixing rod 312 is used to embed into the insulation material or the wall, and the hollow structure of the first fixing rod 312 is used to embed fixing nails 32. The first annular protrusion 315 is used to limit the installation of the fixing nail 32, and the cross groove 319 is used to embed the fixing nail 32, so that the fixing nail 32 is flush with the top plate 311, thereby preventing the fixing nail 32 from affecting the subsequent plastering.

[0030] In embodiment 2, the fixing nail 32 includes a cross plate 321 and a second fixing rod 322. One end of the second fixing rod 322 is fixedly connected to the middle of the cross plate 321. The second fixing rod 322 extends away from the cross plate 321. An elastic plate 323 is located on the second fixing plate. The second fixing plate is fixedly connected to two second annular protrusions 324. The second annular protrusions 324 are located on the side of the elastic plate 323 away from the cross plate 321. A first interval 326 is provided between the second annular protrusion 324 closest to the elastic plate 323 and the elastic plate 323. A second interval 327 is provided between the two second annular protrusions 324. A first annular protrusion 315 is embedded in the first interval 326. The first interval 326 and the second interval 327 have the same height. The width of the first interval 326 is the same as the height of the cross groove 319. The cross plate 321 is embedded in the cross groove 319. The distance between the first interval 326 and the cross plate 321 is the same as the distance between the first annular protrusion 315 and the cross groove 319. The cross plate 321 facilitates the installation of the fixing nail 32 by the operator. The second fixing rod 322 is used to embed into the first fixing rod 312, thereby allowing the elastic plate 323 fixed to the second fixing rod 322 to be installed into the first fixing rod 312, thus fixing the fastener 31. The second annular protrusion 324 is used to cooperate with the first annular protrusion 315 to limit the second fixing rod 322. The first interval 326 and the second interval 327 are used to embed the first annular protrusion 315. The width of the first interval 326 is the same as the height of the cross groove 319, so that when the first annular protrusion 315 is embedded in the first interval 326, the cross plate 321 can be perfectly embedded in the cross groove 319. The width of the first interval 326 refers to the distance from the side of the second annular protrusion 324 facing the elastic plate 323 to the elastic plate 323, and the height of the cross groove 319 refers to the distance between the two end faces of the cross groove 319.

[0031] In Embodiment 2, a limiting strip 316 is fixedly connected to the inner wall of the first fixing rod 312, and the limiting strip 316 is parallel to the first fixing rod 312. A limiting groove 325 is provided on the outer wall of the second fixing rod 322, and the limiting strip 316 and the limiting groove 325 are positioned correspondingly. The cross-section of the limiting strip 316 is the same as the cross-sectional structure of the limiting groove 325. The combination of the limiting strip 316 and the limiting groove 325 is used to guide the installation direction of the fixing nail 32 during installation, allowing the fixing nail 32 to move on a pre-set track, thus facilitating the installation of the fixing nail 32. The length of the limiting strip 316 should be limited so that when the first annular protrusion 315 is embedded in the second interval 327, the limiting strip 316 no longer limits the second fixing rod 322.

[0032] In Embodiment 2, several auxiliary protrusions 313 are provided on the edge of the top plate 311. The auxiliary protrusions 313 extend away from the top plate 311, and their extension direction is the same as that of the first fixing rod 312. The auxiliary protrusions 313 are used to embed into the insulation material, further fixing the fixing member 31, so that the fixing member 31 can more stably fix the connection between the grid 1 and the insulation material, while dispersing and offsetting the stress caused by the shrinkage of the insulation material.

[0033] The working process of Example 1: The mesh 1 is fixed to the insulation material by embedding it into the insulation material through needle punching 2, and the mesh 1 at the joint of the insulation material can be extended to cover at least three intersection points.

[0034] The working process of Example 2 is as follows: First, the mesh 1 is fixed to the insulation material by embedding it into the insulation material through needle punching 2, ensuring that the mesh 1 extends to cover at least three intersection points at the joints of the insulation material. Then, the first fixing rod 312 of the fixing member 31 is inserted through the mesh 1 into the insulation material and embedded in the wall (an opening corresponding to the first fixing rod 312 should be made in the wall before embedding), ensuring that the first fixing rod 312 is located in the grid of the mesh 1, and that the auxiliary protrusion 313 is embedded in the insulation material one grid 1 grid away from the first fixing rod 312. Next, insert the fixing nail 32 into the first fixing rod 312 along the limiting strip 316, and when the first annular protrusion 315 is embedded into the second interval 327, rotate the fixing nail 32 so that the elastic plate 323 pops out from the fixing slot 314 and is embedded in the first fixing rod 312 and the wall or insulation material. Finally, push the fixing nail 32 so that the cross plate 321 is embedded into the cross groove 319, and at the same time the first annular protrusion 315 is embedded into the first interval 326, thus completing the installation of the fixing structure 3.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
