Description

Technical Field

[0001] This invention relates to the field of prefabricated steel mesh connection technology, and more specifically to a connector for prefabricated steel mesh. Background Technology

[0002] Prefabricated steel mesh fencing is a fence system composed of components such as posts, beams, mesh panels, and connectors. It is currently the most widely used type of fencing product. Prefabricated fencing is widely used for protective fencing in highways, railways, airports, squares, gardens, and other locations due to its advantages such as easy installation, aesthetically pleasing appearance, long service life, and no environmental pollution.

[0003] Traditional prefabricated steel mesh is connected and fixed with bolts. However, as the service time increases, the joints of the prefabricated steel mesh will gradually loosen due to vibration, sunlight and other factors, which will reduce the service life of the prefabricated steel mesh.

[0004] Therefore, in order to improve the connection stability of prefabricated steel mesh, a prefabricated steel mesh connector is needed to improve the actual connection stability. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a prefabricated steel mesh connector that can effectively improve connection stability and prevent loosening.

[0006] This invention provides a prefabricated steel mesh connector, comprising: a fixing main block, an abutment block, and a reinforcing member; the fixing main block has a fixing groove and a connecting hole; the abutment block has an abutment groove and a mounting hole; the reinforcing member penetrates the outer wall of the abutment block and is installed in the fixing groove, wherein one side of the reinforcing member abuts against the outer wall of the abutment block, and the other side of the reinforcing member abuts against the fixing groove of the fixing main block; the abutment block comprises two oppositely arranged blocks, and the two abutment blocks are detachably connected through the mounting hole; wherein the fixing main block comprises two blocks, and the two fixing main blocks are detachably connected to the abutment blocks through the connecting hole and the mounting hole.

[0007] Furthermore, the reinforcing member is shaped like a helical spring, and both ends of the reinforcing member are provided with connecting and fixing threaded sections. In practical applications, the reinforcing member's shape is similar to a spring, so that in actual operation, the internal pressure of the stretched spring achieves compression of the outer surface of the abutment block. In this way, the two relatively connected abutment blocks can be effectively compacted. In addition, to ensure the effective abutment of the spring against the abutment block, a helical groove is provided on the surface of the abutment block, and the reinforcing member abuts into the helical groove; in this way, the abutment block can be effectively prevented from slipping off.

[0008] Furthermore, the main fixing block is also provided with two fixing holes, which are located tangentially to the fixing groove and respectively in the vertical direction of the fixing groove. The connecting fixing threaded section of the reinforcing member passes through the fixing hole and is detachably connected to the connecting fixing threaded section by a nut. In practical applications, the purpose of this fixing hole is to facilitate the installation of a spring-like reinforcing member into the fixing groove through the fixing hole. On the other hand, the connecting fixing threaded section extending from the fixing hole is located tangentially to the fixing groove, that is, perpendicular to the outer surface of the main fixing block, which also makes it easier to fix with a nut-like connector. This allows it to directly abut against a flat surface during installation, thus facilitating installation and positioning and reducing the complexity of installation and disassembly.

[0009] Furthermore, it also includes a sealing ring. The fixing main block is also provided with an abutment plate, and the abutment plate has two locations, one at the top and one at the bottom, located outside the fixing groove. The sealing ring is installed between the two fixing main blocks and abuts against each of the fixing main blocks. In actual design, the sealing ring is made of graphite and polytetrafluoroethylene. The working purpose of the sealing ring is to isolate the exchange of gases inside and outside the fixing groove. In this way, it can reduce the corrosion of the inner wall of the fixing groove, maintain stable connection, and facilitate subsequent work.

[0010] Furthermore, it also includes a combustion element, which is disposed within the main fixing block and located within the fixing groove. The main fixing block is also provided with a combustion hole, through which an external ignition device ignites the combustion element. In actual design, the purpose of this design is to create a negative pressure chamber in the fixing groove after installation by burning the air in the fixing groove. On the one hand, the negative pressure ensures a more stable connection, and on the other hand, the negative pressure also causes the two ends of the reinforcing member to contract inward, thus creating an internal pulling force on the aforementioned connecting threaded section, making the connection between the connecting threaded section and the external nut more stable. In actual ignition, the external ignition device uses a needle lighter; it enters the fixing groove to ignite the combustion element, thereby consuming the air in the fixing groove.

[0011] Furthermore, it also includes a one-way valve, which is installed inside the combustion hole; the combustion element includes a fixed mesh basket located inside the fixed groove and close to the combustion hole, and the fixed mesh basket contains ignition material. In actual design, the one-way valve adopts a design similar to a basketball valve and uses butyl rubber, a burn-resistant rubber material. In this way, combustion inside the fixed groove will not ignite the one-way valve, and the ignition material used is cotton soaked in gasoline.

[0012] Furthermore, it also includes a retaining nut having an internal thread section; the thread section is detachably connected to the connecting retaining thread section. In actual design, the internal thread section in this design is similar to that of a common nut, thus facilitating installation and disassembly.

[0013] Furthermore, it also includes a locking sleeve, and the fixing nut also has a locking section, wherein the locking section has an inner groove, the inner groove being located near the internal thread section; the locking sleeve has at least one snap-fit ​​section, the snap-fit ​​section slidingly abutting against the locking section, and one end of the snap-fit ​​section extending into the inner groove. In actual design, the purpose of the locking sleeve in this design is to lock and fix the nut. In actual work, this assembled steel mesh is mostly used outdoors, which means that the connecting parts used to connect and fix the assembled steel mesh are often subjected to various external forces and vibrations. As a result, the nut is easily moved, which makes the connecting parts unstable. The fixing nut in this device effectively solves this problem. Through the combustion effect generated in the fixing groove, a negative pressure is formed in the fixing groove, which facilitates the locking sleeve abutting against the fixing hole position, thus facilitating the snap-fit ​​section to embed into the inner wall of the inner groove; this forms a snap-fit ​​abutting effect, so that the fixing nut not only has the traditional thread fixing effect, but also the slot snap-fit ​​fixing effect. This greatly ensures stability and effectively improves the stability of the connector during actual use.

[0014] Furthermore, the locking sleeve also has an abutment washer, one side of which is fixedly disposed on the surface of the locking sleeve, and the other side of which abuts against the surface of the fixing block.

[0015] As can be seen from the above technical solution, the beneficial effects of the present invention for a prefabricated steel mesh connector are as follows:

[0016] In practical applications, the design involves three main components: a fixing block, abutment block, and reinforcing member. First, two abutment blocks are installed at the joint of the prefabricated steel mesh and secured with bolts. Then, the fixing block is installed outside the abutment blocks, and the reinforcing member provides secondary fixation. This two-stage fixing method significantly enhances the multiple fixing effects, ensuring connection stability and improving the actual service life of the prefabricated steel mesh.

Detailed Implementation

[0027] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0028] The basic implementation examples are as follows: Figures 1 to 6 As shown:

[0029] Example 1:

[0030] like Figures 1-6 As shown in the figure, the connector for assembled steel mesh provided in this embodiment can effectively improve connection stability, prevent loosening, and increase the actual service life of assembled steel mesh.

[0031] A prefabricated steel mesh connector of the present invention includes: a fixing main block 1, an abutment block 2, and a reinforcing member 3; the fixing main block 1 has a fixing groove 11 and a connecting hole 12; the abutment block 2 has an abutment groove 21 and a mounting hole 22; the reinforcing member 3 penetrates the outer wall of the abutment block 2 and is installed in the fixing groove 11, wherein one side of the reinforcing member 3 abuts against the outer wall of the abutment block 2, and the other side of the reinforcing member 3 abuts against the fixing groove 11 of the fixing main block 1; the abutment block 2 has two oppositely arranged blocks, and the two blocks are detachably connected through the mounting hole 22; wherein the fixing main block 1 has two blocks, and the two fixing main blocks 1 are detachably connected to the abutment block 2 through the connecting hole 12 and through the mounting hole 22. In practical work, the three main components involved in this design—fixed main block 1, abutment block 2, and reinforcing member 3—are arranged as follows: First, two abutment blocks 2 are installed at the connection points of the prefabricated steel mesh and then fixed with bolts. Then, the fixed main block 1 is installed on the outside of the abutment blocks 2, and the reinforcing member 3 is used to fix the abutment blocks 2 a second time. Through this two-stage fixing method, multiple fixing effects are greatly achieved, thereby ensuring connection stability and improving the actual service life of the prefabricated steel mesh.

[0032] In this embodiment, to achieve more comprehensive contact and compression of the abutment block 2, the reinforcing member 3 is in the shape of a helical spring, and both ends of the reinforcing member 3 are provided with connecting and fixing threaded sections 31. In practical application, the reinforcing member 3 is similar in shape to a spring, so that in actual operation, the internal pressure of the stretched spring can achieve compression of the outer surface of the abutment block 2. In this way, the two relatively connected abutment blocks 2 can be effectively compacted.

[0033] In this embodiment, the fixing block 1 is further provided with two fixing holes 13, wherein the fixing holes 13 are located in the tangential direction of the fixing groove 11 and are respectively located in the vertical direction of the fixing groove 11; the connecting fixing threaded section 31 of the reinforcing member 3 passes through the fixing hole 13 and is detachably connected to the connecting fixing threaded section 31 by a nut. In practical applications, the purpose of the fixing hole 13 is to facilitate the installation of the reinforcing member 3, which is similar to a spring, into the fixing groove 11 through the fixing hole 13. On the other hand, the connecting fixing threaded section 31 extending from the fixing hole 13 is located in the tangential direction of the fixing groove 11, that is, perpendicular to the outer surface of the fixing block 1, which makes it easier to fix with a nut-like connector; so that it can directly abut against the plane during installation, which facilitates installation and positioning and reduces the complexity of installation and disassembly.

[0034] In this embodiment, a sealing ring 4 is also included. The fixing main block 1 is further provided with an abutment plate 14, which has two locations, upper and lower, and is located outside the fixing groove 11. The sealing ring 4 is installed between the two fixing main blocks 1 and abuts against each of the fixing main blocks 1. In actual design, the sealing ring 4 is made of graphite and polytetrafluoroethylene. The working design purpose of the sealing ring 4 is to isolate the internal and external gas exchange of the fixing groove 11. In this way, the corrosion of the inner wall of the fixing groove 11 can be reduced, and stable connection can be maintained, which facilitates subsequent work.

[0035] In this embodiment, a combustion element 5 is also included. The combustion element 5 is disposed within the fixed main block 1 and located within the fixed groove 11. The fixed main block 1 is also provided with a combustion hole 15, through which an external ignition device ignites the combustion element 5. In actual design, the purpose of this design is to achieve a negative pressure chamber in the fixed groove 11 after installation by burning the air in the fixed groove 11. On the one hand, the negative pressure ensures a more stable connection effect, and on the other hand, the negative pressure also causes the two ends of the reinforcing member 3 to contract inward, thus creating an internal pulling force on the aforementioned connecting and fixing threaded section 31, making the connection effect between the connecting and fixing threaded section 31 and the external nut more stable. Simultaneously, in actual ignition, the external ignition device uses a needle lighter; it enters the fixed groove 11 to ignite the combustion element 5, thereby consuming the air in the fixed groove 11.

[0036] In this embodiment, a one-way valve 6 is also included, which is installed inside the combustion hole 15. The combustion element 5 includes a fixed basket 51, which is located inside the fixed groove 11 and close to the combustion hole 15. The fixed basket 51 contains ignition material. In actual design, the one-way valve 6 adopts a design similar to a basketball valve and uses butyl rubber, a burn-resistant rubber material. In this way, combustion inside the fixed groove 11 will not ignite the one-way valve 6. The ignition material used is cotton soaked in gasoline.

[0037] In this embodiment, a fixing nut 7 is also included, which has an internal thread section 71; the thread section is detachably connected to the connecting fixing thread section 31. In actual design, the internal thread section 71 in this design is similar to that of a common nut, which facilitates installation and disassembly.

[0038] In this embodiment, a locking sleeve 8 is also included. The fixing nut 7 further has a locking section 72, wherein the locking section 72 has an inner groove 720 located near the internal thread section 71. The locking sleeve 8 has at least one latching section 81, which slides against the locking section 72, and one end of the latching section 81 extends into the inner groove 720. In actual design, the purpose of the locking sleeve 8 in this design is to lock and fix the nut 7. In actual work, this assembled steel mesh is mostly used outdoors, which means that the connectors used to connect and fix the assembled steel mesh are often subjected to various external forces and vibrations. This can easily cause the nut to shift, leading to instability in the connector. The fixing nut 7 in this device effectively solves this problem. The combustion effect within the fixing groove 11 creates a negative pressure, facilitating the locking sleeve 8 to abut against the fixing hole 13. This allows the snap-fit ​​segment 81 to embed into the inner wall of the inner groove 720, creating a snap-fit ​​effect. Therefore, the fixing nut 7 not only provides traditional threaded fastening but also a snap-fit ​​fastening effect. This greatly ensures stability and effectively improves the overall stability of the connector during actual use.

[0039] In this embodiment, the locking sleeve 8 also has an abutment washer 82, one side of the abutment washer 82 is fixedly disposed on the surface of the locking sleeve 8, and the other side of the abutment washer 82 abuts against the surface of the fixing main block 1.

[0040] Example 2:

[0041] like Figure 7 As shown, the abutment block 2 with a spiral groove 101 provided in this embodiment is a further improvement on the abutment block 2 provided in another embodiment. The spiral groove 101 enables the reinforcing member 3, which is similar to a spring, to effectively abut against the abutment block 2. The reinforcing member 3 abuts into the spiral groove 101. In this way, it can effectively ensure that the abutment block 2 will not slip off, thereby increasing the clamping force.

[0042] In actual operation, firstly, the two abutment blocks 2 are installed at the joint of the assembled steel mesh. Bolts are passed through the mounting holes 22 to connect the two abutment blocks 2 together. Then, the fixing blocks 1 of each block are passed through the bolts mentioned above, and the other fixing block 1 is also passed through the bolt on the other side. At this point, the sealing ring 4 is placed between the two fixing blocks 1, and then the two fixing blocks 1 are pressed together and fixed. Next, the reinforcing member 3, which is a spring-like workpiece, is inserted through one of the fixing holes 13 and rotated until it flows out from the other fixing hole 13. Then, the locking sleeves 8 are placed on the bolts and the connecting fixing thread section 31, and the fixing nuts 7 are installed on the locking sleeves 8 and continuously screwed in until they stop moving. Finally, a needle ignition device is passed through the combustion hole 15 to ignite the ignition material in the combustion element 5. Then, during each maintenance, the height of the abutment washer 82 is observed to change; if it becomes longer, a second ignition is performed.

[0043] In summary, this type of prefabricated steel mesh connector is not only reasonably designed but also easy to operate. By achieving an oxygen-free design, the actual service life of the connector is greatly extended. Furthermore, the negative pressure formed by the oxygen-free interior creates internal tension, which facilitates the transformation of the locking sleeve 8 and the fixing nut 7 from a snap-fit ​​fixing to a plug-in fixing effect, greatly improving the fixing stability. Therefore, it is suitable for industry promotion.
