Description

Technical Field

[0001] This utility model relates to the field of building materials technology, and in particular to a split connector for limiting installation of three-dimensional fiber mesh. Background Technology

[0002] Three-dimensional fiber mesh is a three-dimensional fiber material integrally formed using a three-dimensional weaving process. As a reinforcement, it can significantly improve the tensile, flexural, and impact resistance, as well as crack resistance, of cement-based materials. Three-dimensional fiber mesh reinforced high-performance cement-based materials show promising application prospects in curtain wall panels, suspended floor slabs, formwork without removal, modular precast panels, and crack repair applications. The micro-truss structure of the three-dimensional fiber mesh provides highly efficient reinforcement, but also imposes high-precision requirements on its installation. The spatial position of the three-dimensional fiber mesh within the cement-based panel determines the thickness of the protective layer and the synergistic effect, thus affecting the appearance and mechanical properties of the component. Therefore, high-precision installation of the three-dimensional fiber mesh is a key control point in the preparation process of three-dimensional fiber mesh reinforced cement-based panels.

[0003] Three-dimensional fiber mesh reinforced cement-based panels typically feature large panel sizes, thin thicknesses, high density, good appearance, and back-bolted connections. Depending on the application and design requirements, they can generally be formed using either spraying or casting processes. However, the installation of three-dimensional fiber meshes requires a flat mesh surface, accurate spatial positioning, appropriate protective layer thickness, reliable connectors, and no impact on concrete compaction. Currently, there is no standardized practice for the installation of three-dimensional fiber meshes. In single-sided formwork systems using spraying, one side of the protective layer is usually sprayed first before placing the mesh, resulting in issues such as mesh sinking and bulging of embedded connectors. In double-sided formwork systems using casting, small pads are typically placed on both sides of the mesh to control the protective layer thickness, leading to problems such as poor mesh flatness, mesh misalignment, and low connection reliability.

[0004] Therefore, there is a need to provide a split connector for limiting the installation of three-dimensional fiber mesh, which can solve the problems of poor mesh flatness, mesh offset and low connection reliability in the installation of three-dimensional fiber mesh in the prior art. Summary of the Invention

[0005] The purpose of this invention is to provide a split connector for limiting the installation of three-dimensional fiber mesh, which can solve the problems of poor mesh flatness, mesh offset and low connection reliability in the installation of three-dimensional fiber mesh in the prior art.

[0006] This utility model is implemented as follows:

[0007] A split-type connector for limiting installation of three-dimensional fiber mesh includes a male connector, a female connector, and a temporary fixing component. The male connector includes a male connecting end and a male limiting plate, and the female connector includes a female connecting end and a female limiting plate. One end of the female connecting end is matched and connected to one end of the male connecting end to form a connecting component, which penetrates the three-dimensional fiber mesh. The male limiting plate is located at the other end of the male connecting end, and the female limiting plate is located at the other end of the female connecting end, so that the male and female limiting plates can fit against the two end faces of the three-dimensional fiber mesh. The male connector and / or the female connector are temporarily connected and fixed to the side template of the three-dimensional fiber mesh reinforced cement-based board through the temporary fixing component, so that the three-dimensional fiber mesh is located inside the three-dimensional fiber mesh reinforced cement-based board.

[0008] When the side formwork of the three-dimensional fiber mesh reinforced cement-based board is a double-sided formwork, that is, the side formwork includes a first side formwork and a second side formwork, and the three-dimensional fiber mesh is arranged in parallel between the first side formwork and the second side formwork; the temporary fastener includes a first fastener and a second fastener, the male connector is temporarily connected and fixed to the first side formwork through the first fastener, and the female connector is temporarily connected and fixed to the second side formwork through the second fastener.

[0009] When the side formwork of the three-dimensional fiber mesh reinforced cement-based board is a single-sided formwork, that is, the side formwork includes a second side formwork, and the three-dimensional fiber mesh is arranged parallel to the side of the second side formwork; the temporary fastener includes a second fastener, and the female connector is temporarily connected and fixed to the second side formwork through the second fastener.

[0010] When the side formwork of the three-dimensional fiber mesh reinforced cement-based board is a double-sided formwork, the male connector also includes a male limiting end. The male limiting end is set on the surface of the male limiting plate away from the male connector end. The first fixing member passes through the first side formwork and matches and connects with the male limiting end.

[0011] The male connector, male limiting plate, male limiting end and first fixing member are coaxially arranged; the diameter of the male limiting plate is larger than the mesh width of the three-dimensional fiber mesh, and the thickness of the male limiting end is consistent with the thickness of the concrete protective layer on the first side template side.

[0012] The male head limiting end is a first internal threaded sleeve, the first fixing component is a first bolt, the threaded section of the first bolt passes through the first side template and is matched and screwed with the first internal threaded sleeve, the bolt head of the first bolt is pressed against the surface of the first side template away from the three-dimensional fiber mesh, and the first internal threaded sleeve is pressed against the surface of the first side template close to the three-dimensional fiber mesh.

[0013] The female connector also includes a female limiting end, which is located on the surface of the female limiting plate away from the female connector. The second fixing member passes through the second side template and is matched and connected to the female limiting end.

[0014] The female head connecting end, female head limiting plate, female head limiting end and second fixing member are coaxially arranged; the diameter of the female head limiting plate is larger than the mesh width of the three-dimensional fiber mesh, and the thickness of the female head limiting end is consistent with the thickness of the concrete protective layer on the second side template side.

[0015] The female head limiting end is a second internal threaded sleeve, and the second fixing component is a second bolt. The threaded section of the second bolt passes through the second side template and is matched and screwed with the second internal threaded sleeve of the female head limiting end. The bolt head of the second bolt is pressed against the surface of the second side template away from the three-dimensional fiber mesh, and the second internal threaded sleeve is pressed against the surface of the second side template close to the three-dimensional fiber mesh.

[0016] The female connector is a third internal threaded sleeve, and the male connector includes a connecting cylinder and a connecting screw. The connecting screw is screwed into the third internal threaded sleeve, so that the third internal threaded sleeve and the connecting cylinder are connected to form a cylindrical connecting member. The thickness of the cylindrical connecting member is the same as the thickness of the three-dimensional fiber mesh, and the diameter of the cylindrical connecting member does not exceed the mesh width of the three-dimensional fiber mesh, so that the cylindrical connecting member perpendicularly penetrates the mesh of the three-dimensional fiber mesh.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] 1. This utility model, with its male connector, female connector, and temporary fixing component, adopts a split design, which is respectively set on both sides of the three-dimensional fiber mesh. It can control the spatial position and protective layer thickness of the three-dimensional fiber mesh with high precision without damaging the structure of the three-dimensional fiber mesh, and is suitable for the limiting installation of three-dimensional fiber meshes with different mesh widths. The split connector is efficiently connected to the three-dimensional fiber mesh and reliably connected to the side template through the temporary fixing component, effectively solving the problems of poor mesh flatness, mesh offset, and low connection reliability of three-dimensional fiber mesh reinforced cement-based boards.

[0019] 2. This utility model has the advantages of convenient construction, precise control, and safety and reliability. Targeting the characteristics of large plate size and small thickness of high-performance cement-based boards and the flexibility, elasticity, and micro-truss structure of three-dimensional fiber mesh, it can be widely applied to the preparation process of different three-dimensional fiber mesh reinforced cement-based board products, which is of great significance for improving the production efficiency and product quality of three-dimensional fiber mesh reinforced cement-based boards.

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Please see the appendix Figure 1 To be continued Figure 10 A split-type connector for limiting installation of a three-dimensional fiber mesh includes a male connector 100, a female connector 200, and a temporary fixing component. The male connector 100 includes a male connecting end 121 and a male limiting plate 122, and the female connector 200 includes a female connecting end 211 and a female limiting plate 212. One end of the female connecting end 211 is matched and connected to one end of the male connecting end 121 to form a connecting component, and the connecting component penetrates the three-dimensional fiber mesh. The male limiting plate 122 is disposed at the other end of the male connecting end 121, and the female limiting plate 212 is disposed at the other end of the female connecting end 211, so that the male limiting plate 122 and the female limiting plate 212 can fit against the two end faces of the three-dimensional fiber mesh 400. The male connector 100 and / or the female connector 200 are temporarily connected and fixed to the side template of the three-dimensional fiber mesh reinforced cement-based board through the temporary fixing component, so that the three-dimensional fiber mesh 400 is disposed within the three-dimensional fiber mesh reinforced cement-based board.

[0033] The three-dimensional fiber mesh 400 is connected by a split connector structure consisting of male connector 100 and female connector 200. The three-dimensional fiber mesh 400 is stably and reliably connected to the side template of the three-dimensional fiber mesh reinforced cement-based board through male connector 100 and female connector 200 via temporary fasteners. This can solve the problems of three-dimensional fiber mesh misalignment and low connection reliability in the existing technology.

[0034] Meanwhile, the thickness of the concrete protective layer on both sides of the three-dimensional fiber mesh 400 is controlled by connecting the male connector 100 and / or the female connector 200 to the temporary fastener.

[0035] Preferably, both the male connector 100 and the female connector 200 can be made of stainless steel to ensure good load-bearing capacity and durability. This ensures connection strength while preventing contamination and discoloration of the three-dimensional fiber mesh reinforced cement-based board caused by steel corrosion. The number and spacing of the male connector 100 and female connector 200 can be adaptively adjusted according to the size and installation requirements of the three-dimensional fiber mesh 400. Back bolt holes, matching the number of separate connectors, are pre-drilled at corresponding positions on the side template to improve the flatness of the three-dimensional fiber mesh 400 and further enhance the connection reliability of the three-dimensional fiber mesh 400.

[0036] Please see the appendix Figure 2 Appendix Figure 5 and attached Figure 6When the side formwork of the three-dimensional fiber mesh reinforced cement-based board is a double-sided formwork, that is, the side formwork includes a first side formwork 510 and a second side formwork 520, and the three-dimensional fiber mesh 400 is arranged in parallel between the first side formwork 510 and the second side formwork 520; the temporary fixing component includes a first fixing component 310 and a second fixing component 320, the male connector 100 is temporarily connected and fixed to the first side formwork 510 through the first fixing component 310, and the female connector 200 is temporarily connected and fixed to the second side formwork 520 through the second fixing component 320.

[0037] When using double-sided formwork for three-dimensional fiber mesh reinforced cement-based panels, the three-dimensional fiber mesh 400 can be reliably installed between the first side formwork 510 and the second side formwork 520 via the first fixing member 310 and the second fixing member 320. Furthermore, the thickness of the concrete protective layer on both sides of the three-dimensional fiber mesh 400 can be controlled independently through the connection between the first fixing member 310 and the male connector 100, and the connection between the female connector 200 and the second fixing member 320. This allows for flexible control of the concrete protective layer thickness on both sides, flexibly meeting the manufacturing requirements of three-dimensional fiber mesh reinforced cement-based panels.

[0038] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 4 When the side formwork of the three-dimensional fiber mesh reinforced cement-based board is a single-sided formwork, that is, the side formwork includes a second side formwork 520, and the three-dimensional fiber mesh 400 is arranged parallel to the side of the second side formwork 520; the temporary fixing component includes a second fixing component 320, and the female connector 200 is temporarily connected and fixed to the second side formwork 520 through the second fixing component 320.

[0039] When a single-sided formwork (i.e., the second-side formwork 520) is used for a three-dimensional fiber mesh reinforced cement-based slab, the three-dimensional fiber mesh 400 is connected to the second-side formwork 520 via a female connector 200 and a second fixing member 320, ensuring a reliable connection between the three-dimensional fiber mesh 400 and the second-side formwork 520. Furthermore, the thickness of the concrete protective layer on one side of the three-dimensional fiber mesh 400 can be controlled through the connection between the female connector 200 and the second fixing member 320.

[0040] Alternatively, a first side template 510 can be set only on the male connector 100 side as a single-side template. Its installation method is the same as that of the second side template 520 set on the female connector 200 side, which will not be described in detail here.

[0041] Please see the appendix Figure 7 and attached Figure 8When the side template of the three-dimensional fiber mesh reinforced cement-based board is a double-sided template, the male connector 100 also includes a male limiting end 123. The male limiting end 123 is set on the surface of the male limiting plate 122 away from the male connector 121. The first fixing member 310 passes through the first side template 510 and is matched and connected with the male limiting end 123.

[0042] The male head limiting end 123 can be used to control the distance between the male head limiting plate 122 and the first side template 510, thereby controlling the distance between the three-dimensional fiber mesh 400 and the first side template 510, that is, the thickness of the concrete protective layer on the side of the first side template 510.

[0043] Meanwhile, the male head limiting end 123 facilitates the temporary connection and fixation between the male head limiting end 123 and the first fixing member 310, and also facilitates the disassembly of the first fixing member 310 and the first side template 510 after the three-dimensional fiber mesh reinforced cement-based board is formed.

[0044] Please see the appendix Figure 7 and attached Figure 8 The male connector 121, male limiting plate 122, male limiting end 123 and the first fixing member 310 are coaxially arranged; the diameter of the male limiting plate 122 is greater than the mesh width of the three-dimensional fiber mesh 400, and the thickness of the male limiting end 123 is consistent with the thickness of the concrete protective layer on the side of the first side template 510.

[0045] The diameter of the male head limiting disc 122 is selected adaptively based on the mesh width of the three-dimensional fiber mesh 400. Preferably, the diameter of the male head limiting disc 122 is not less than three times the mesh width of the three-dimensional fiber mesh 400, providing a large contact area to ensure that the male head limiting disc 122 can effectively limit the three-dimensional fiber mesh 400 after it is attached to one surface, preventing the three-dimensional fiber mesh 400 from slipping. The thickness of the male head limiting end 123 can be adaptively adjusted according to the thickness requirements of the concrete protective layer.

[0046] The coaxial male connector 121, male limiting plate 122, male limiting end 123 and first fixing member 310 can ensure that the male connector 100 is subjected to uniform force and ensure the stability of axial force transmission after installation.

[0047] Please see the appendix Figure 7 and attached Figure 8 The male head limiting end 123 is a first internal threaded sleeve, the first fixing member 310 is a first bolt, the threaded section of the first bolt passes through the first side template 510 and is matched and screwed with the first internal threaded sleeve, the bolt head of the first bolt is pressed against the surface of the first side template 510 away from the three-dimensional fiber mesh 400, and the first internal threaded sleeve is pressed against the surface of the first side template 510 close to the three-dimensional fiber mesh 400.

[0048] The connection between the first internal threaded sleeve and the threaded section of the first bolt is screwed together, ensuring reliable connection while facilitating quick assembly and disassembly. The length of the threaded section of the first bolt and the length of the first internal threaded sleeve can be adaptively adjusted according to the thickness requirements of the concrete protective layer.

[0049] Please see the appendix Figure 9 and attached Figure 10 When the side template of the three-dimensional fiber mesh reinforced cement-based board is a double-sided template or a single-sided template, the female head connector 200 also includes a female head limiting end 213. The female head limiting end 213 is set on the surface of the female head limiting plate 212 away from the female head connector 211. The second fixing member 320 passes through the second side template 520 and is matched and connected with the female head limiting end 213.

[0050] When using double-sided formwork for three-dimensional fiber mesh reinforced cement-based panels, in addition to the male head connector 100 having a male head limiting end 123, a female head limiting end 213 is also provided on the female head connector 200. This ensures reliable connection between the three-dimensional fiber mesh 400 and the second side formwork 520 and precise control of the concrete protective layer thickness on the second side formwork 520 through the connection between the female head limiting end 213 and the second fixing member 320.

[0051] The installation methods and principles of the female head limiting end 213, the second fixing member 320, and the second side template 520 are the same as those of the male head limiting end 123, the first fixing member 310, and the first side template 510, and will not be repeated here.

[0052] Please see the appendix Figure 9 and attached Figure 10 The female head connecting end 211, female head limiting plate 212, female head limiting end 213, and second fixing member 320 are coaxially arranged; the diameter of the female head limiting plate 212 is greater than the mesh width of the three-dimensional fiber mesh 400, and the thickness of the female head limiting end 213 is consistent with the thickness of the concrete protective layer on the side of the second side template 520.

[0053] The diameter of the female head limiting plate 212 is adapted to the mesh width of the three-dimensional fiber mesh 400. Preferably, it can be the same as the diameter of the male head limiting plate 122, and not less than three times the mesh width of the three-dimensional fiber mesh 400, so as to have a large contact area. This ensures that after the female head limiting plate 212 is attached to the other side of the three-dimensional fiber mesh 400, it can effectively limit the three-dimensional fiber mesh 400, so as to effectively connect the split connector with the three-dimensional fiber mesh 400 and prevent the three-dimensional fiber mesh 400 from slipping. The thickness of the female head limiting end 213 can be adapted to the thickness requirements of the concrete protective layer.

[0054] The coaxially arranged female connector 211, female limiting plate 212, female limiting end 213, and second fixing member 320 can ensure that the male connector 100 is subjected to uniform force and ensure the stability of axial force transmission after installation.

[0055] Please see the appendix Figure 9 and attached Figure 10 The female head limiting end 213 is a second internal threaded sleeve, and the second fixing member 320 is a second bolt. The threaded section of the second bolt passes through the second side template 520 and is matched and screwed with the second internal threaded sleeve of the female head limiting end 213. The bolt head of the second bolt is pressed against the surface of the second side template 520 away from the three-dimensional fiber mesh 400, and the second internal threaded sleeve is pressed against the surface of the second side template 520 close to the three-dimensional fiber mesh 400.

[0056] The connection between the second internal threaded sleeve and the threaded section of the second bolt is screwed together, ensuring reliable connection while facilitating quick assembly and disassembly. The length of the threaded section of the second bolt and the length of the second internal threaded sleeve can be adaptively adjusted according to the thickness requirements of the concrete protective layer.

[0057] Please see the appendix Figure 7 To be continued Figure 10 The female connecting end 211 is a third internal threaded sleeve, and the male connecting end 121 includes a connecting cylinder and a connecting screw. The connecting screw is screwed into the third internal threaded sleeve, so that the third internal threaded sleeve and the connecting cylinder are connected to form a cylindrical connecting member. The thickness of the cylindrical connecting member is the same as the thickness of the three-dimensional fiber mesh 400, and the diameter of the cylindrical connecting member does not exceed the mesh width of the three-dimensional fiber mesh 400, so that the cylindrical connecting member perpendicularly penetrates the mesh of the three-dimensional fiber mesh 400.

[0058] Based on the formwork type of the three-dimensional fiber mesh reinforced cement-based board, i.e., single-sided formwork or double-sided formwork, and the position of the side formwork, i.e., the side formwork is located on the male connector 100 side or on the female connector 200 side, the male connector 100 with or without male head limiting end 123 and the female connector 200 with or without female head limiting end 213 are adaptively selected.

[0059] The connection between the third internal threaded sleeve and the connecting screw is screwed together, ensuring a reliable connection while facilitating quick assembly and disassembly. The lengths of the connecting screw and the third internal threaded sleeve can be adjusted to suit the thickness of the concrete protective layer and the side formwork.

[0060] The diameter of the third internal threaded sleeve is the same as the diameter of the connecting sleeve, and is smaller than the mesh width of the three-dimensional fiber mesh 400, so as to ensure that the connecting component can penetrate the mesh of the three-dimensional fiber mesh 400 without damaging the three-dimensional fiber mesh 400.

[0061] Please see the appendix Figure 8 and attached Figure 10 Preferably, the male limiting end 123 can communicate with the connecting cylinder of the male connecting end 121, extending the connection length and reliability between the first fixing member 310 and the male limiting end 123. The female limiting end 213 can communicate with the female connecting end 211, and after installation, the connecting screw of the male connecting end 121 can abut against the second fixing member 320.

[0062] Please see the appendix Figure 1 To be continued Figure 10 The installation method of this utility model is as follows:

[0063] (1) Place the male connector 100 and the female connector 200 on both sides of the three-dimensional fiber mesh 400 at the reserved positions of the back bolt holes of the side template.

[0064] (2) Pass the male connector 121 and the female connector 211 through the mesh of the three-dimensional fiber mesh 400. Insert the connecting screw of the male connector 121 into the third internal thread sleeve of the female connector 211 and tighten the thread. After tightening, the male limiting plate 122 of the male connector 100 and the female limiting plate 212 of the female connector 200 are respectively attached to the two surfaces of the three-dimensional fiber mesh 400.

[0065] (3) Drill holes at the reserved positions of the back bolt holes on the second side template 510 or the first side template 510 and the second side template 520, and the hole diameter is consistent with the diameter of the first internal thread sleeve of the male head limiting end 123 and the second internal thread sleeve of the female head limiting end 213.

[0066] (4) Double-sided formwork: The three-dimensional fiber mesh 400 with split connectors is placed between the two-sided formwork, so that the male limiting end 123 is pressed against the inner surface of the first side formwork 510 (i.e., the side near the three-dimensional limiting mesh 400), and the female limiting end 213 is pressed against the inner surface of the second side formwork 520 (i.e., the side near the three-dimensional limiting mesh 400). The thickness of the concrete protective layer on both sides of the three-dimensional fiber mesh 400 is controlled by the male limiting end 123 and the female limiting end 213 respectively.

[0067] Single-sided formwork: The three-dimensional fiber mesh 400 with split connectors is placed beside the single-sided formwork, so that the female head limiting end 213 is pressed against the inner surface of the second side formwork 520. The thickness of the concrete protective layer between the three-dimensional fiber mesh 400 and the second side formwork 520 is controlled by the female head limiting end 213.

[0068] (5) Temporary fasteners are used to temporarily connect with male connector 100 and / or female connector 200 through the back bolt holes of the side template to restrict the relative position between the three-dimensional fiber mesh 400 and the side template.

[0069] Double-sided template: The bolt head of the first fixing member 310 is pressed against the outer surface of the first side template 510 (i.e. the side away from the three-dimensional limiting grid 400), and the bolt head of the second fixing member 320 is pressed against the outer surface of the second side template 520 (i.e. the side away from the three-dimensional limiting grid 400), so that the three-dimensional limiting grid 400 and the double-sided template are stably and reliably connected into a whole.

[0070] The bolt head of the second fixing member 320 is tightened against the outer surface of the second side template 520, so that the three-dimensional limiting grid 400 and the second side template 520 are stably and reliably connected into a whole.

[0071] During the installation of the three-dimensional limiting grid 400, the positions of the male connector 100 and the female connector 200 can be interchanged, the positions of the second fixing part 320 and the first fixing part 310 can be interchanged, and the positions of the second side template 520 and the first side template 510 can be interchanged. This does not affect the connection method and reliability between the three-dimensional limiting grid 400 and the side templates. It can be flexibly adjusted according to actual installation requirements, which will not be elaborated here.

[0072] (6) Prepare three-dimensional fiber mesh reinforced cement-based panels using spraying or casting processes.

[0073] (7) After the hardening and curing of the three-dimensional fiber mesh reinforced cement-based board is completed, the temporary fasteners and side formwork are removed.

[0074] Bolt holes are pre-drilled on the side formwork to facilitate the transportation and installation of the three-dimensional fiber mesh reinforced cement-based panels.

[0075] Example 1:

[0076] The thickness of the three-dimensional fiber mesh reinforced cement-based board is 30mm. It adopts a double-sided formwork casting process. The thickness of the three-dimensional fiber mesh 400 is 20mm and the mesh width is 10mm. The thickness of the double-sided concrete protective layer is 5mm. However, it is required that there are no pre-reserved screw holes on one side of the male connector 100.
