Description

Technical Field

[0001] This utility model relates to the field of steel mesh installation, specifically to a high-stability anti-loosening connection device for steel mesh. Background Technology

[0002] In various fields such as building construction, road construction, bridge construction, and protective engineering, steel mesh is widely used as an important structural component to enhance structural strength, improve crack resistance, and ensure overall stability. It is typically composed of multiple transverse and longitudinal steel bars welded or tied together. In practical applications, multiple independent steel mesh sheets often need to be connected and spliced ​​to meet the dimensional requirements of different construction scenarios. Therefore, the quality of the connection between steel mesh sheets directly affects the safety, stability, and service life of the entire engineering structure.

[0003] However, the common steel mesh connection methods currently available on the market have many defects and are difficult to meet the requirements of high-standard projects for connection stability and anti-loosening performance. Traditional connection methods mainly include binding connections, welding connections, and simple snap-fit ​​connections. Among them, binding connections usually use iron wire to tie and fix the intersections of adjacent steel mesh bars. This method is cumbersome to operate, which not only consumes a lot of manpower and time, but also the firmness of the binding points is easily affected by the operator's skill level, the material of the iron wire, and environmental factors (such as vibration and corrosion). After long-term use, the iron wire is prone to loosening and breakage, leading to the failure of the steel mesh connection and causing structural deformation and other safety hazards.

[0004] While welding can achieve high connection strength in the short term, the high temperatures generated during welding can alter the local mechanical properties of the reinforcing steel, leading to problems such as quenching hardening or thermal stress cracking, thus reducing the steel's load-bearing capacity and fatigue resistance. Furthermore, welding is highly dependent on the construction environment; in harsh conditions such as humidity and strong winds, it is difficult to guarantee welding quality. Additionally, welded joints cannot be disassembled or adjusted, making repairs difficult and costly, especially for defects, and hindering future maintenance and modifications.

[0005] Simple snap-fit ​​connections typically use single-structure snap-fit ​​devices to secure the reinforcing bars. These devices often lack effective anti-loosening designs, making them susceptible to relative displacement between the snap-fit ​​and the reinforcing bars under external loads (such as vibrations from vehicle movement or machine operation) or structural expansion and contraction due to temperature changes, leading to loosening of the connection. Furthermore, traditional snap-fit ​​devices have poor adaptability, often only suitable for connecting specific sizes of reinforcing mesh. When dealing with reinforcing meshes of different diameters and spacings, different models of snap-fit ​​devices are required, increasing construction costs and operational complexity. Therefore, we propose a highly stable anti-loosening connection device for reinforcing meshes. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a high-stability anti-loosening connection device for steel mesh, thus solving the aforementioned problems.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a high-stability steel mesh anti-loosening connection device, comprising a rectangular shell, wherein the interior of the rectangular shell is provided with two sets of clamping plate structures that can be mirrored and moved to adjust their positions, and the bottom two sides of the rectangular shell are integrally formed with L-shaped bending portions, one side of the opening of the L-shaped bending portion corresponding to the lower end of the clamping plate structure.

[0008] Preferably, the rectangular shell has an internal groove, and the bottom of the internal groove has a bottom rectangular groove. The upper end of the clamping plate structure is slidably engaged inside the internal groove, and the lower end of the clamping plate structure extends to the outside of the rectangular shell through the bottom rectangular groove.

[0009] Preferably, two bolts are threaded onto the rectangular housing, with the lower ends of the two bolts passing through the internal groove and the bottom rectangular groove to extend to the bottom of the rectangular housing.

[0010] Preferably, the card plate structure consists of an integrally formed bottom card plate and a top card plate. The top card plate is slidably engaged inside the inner groove. The bottom card plate is fixedly installed at the lower end of the top card plate. The bottom card plate extends through the bottom rectangular groove to the bottom of the rectangular shell.

[0011] Preferably, a lead screw is rotatably mounted inside the rectangular housing, and the two ends of the lead screw are respectively provided with external threads in different directions. The two ends of the lead screw are respectively threadedly connected to two top snap-fit ​​plates.

[0012] Preferably, one end of the lead screw extends to the outside of the rectangular housing, and a knob is fixedly installed at the end of the lead screw extending to the outside of the rectangular housing. The addition of the knob facilitates the rotation of the lead screw.

[0013] Compared with the prior art, this utility model provides a high-stability anti-loosening connection device for steel mesh, which has the following beneficial effects:

[0014] I. Significantly improves connection stability and anti-loosening performance, ensuring the safety of engineering structures.

[0015] This device employs a dual-limiting design of an "L-shaped bend + adjustable clamping plate structure" to firmly confine the reinforcing steel mesh between the inner side of the L-shaped bend and the bottom clamping plate, forming a reliable mechanical locking structure. This effectively avoids the problems of wire loosening and breakage in traditional binding connections and relative displacement in simple snap-fit ​​connections. Simultaneously, bolts are used to fix the rectangular shell to the ground or in pre-drilled threaded holes, achieving dual fixation between the device and the installation foundation. Even under long-term external load vibrations (such as vehicle travel or machine operation vibrations) or structural expansion and contraction caused by temperature changes, the connection remains firm, significantly reducing structural deformation and safety hazards caused by connection failure, and providing strong protection for the long-term stability and safety of the engineering structure.

[0016] II. Simplify the construction process and significantly improve construction efficiency.

[0017] Compared to the cumbersome operation of traditional binding connections and the complex process of welding connections, the installation of this device does not require professional technicians or complicated tools: simply align the steel mesh with the gap between the L-shaped bend and the bottom clamping plate, pull it laterally to the bend, and then adjust the bottom clamping plate by rotating the screw to complete the sealing and fixation. Finally, the device is reinforced with bolts. The entire process can be quickly operated by a single person, significantly reducing manpower consumption and construction time. At the same time, it eliminates the need to wait for cooling or deal with weld slag as required by welding connections, and avoids the trouble of repeatedly adjusting the binding points in binding connections, effectively improving the efficiency of steel mesh splicing construction and shortening the project period.

[0018] 3. Compatible with various specifications of steel mesh, reducing construction costs.

[0019] The device features a design that uses a lead screw to move the clamping plate structure in a mirror-like motion, allowing for flexible adjustment of the distance between the bottom clamping plate and the L-shaped bend. When dealing with steel mesh of different diameters and spacings, there is no need to replace different models of connecting parts; simply rotating the knob to adjust the position of the clamping plate structure is sufficient to accommodate the connection needs of different specifications of steel mesh. This feature breaks the limitation of traditional snap-fit ​​connections that require "one specification, one accessory," reducing the types and inventory of connecting parts during construction, lowering the additional costs incurred due to accessory replacement, and avoiding construction delays caused by mismatched accessory models, thus providing effective support for project cost control.

[0020] IV. Avoid damaging the properties of steel reinforcement and extend the service life of the structure.

[0021] Unlike welded connections, this device uses a mechanical interlocking connection method, eliminating the need for high-temperature welding for fixation. This fundamentally avoids the damage to the local mechanical properties of the reinforcing steel caused by high temperatures, effectively preventing problems such as quenching hardening and thermal stress cracking, and ensuring that the reinforcing mesh maintains its original load-bearing capacity and fatigue resistance. Furthermore, the contact between the device's components and the reinforcing steel is flexible and restrained, preventing scratches or damage to the steel surface. This reduces the risk of corrosion caused by surface damage, further extending the service life of the reinforcing mesh and the entire engineering structure, and lowering subsequent maintenance and replacement costs.

[0022] V. Facilitates later disassembly and maintenance, enhancing project flexibility.

[0023] This device eliminates the drawbacks of welded connections that are "one-time fixed and cannot be disassembled." If adjustments, replacements, or engineering modifications are needed later, simply unscrew the bolts and rotate the knob in the opposite direction to adjust the clamping plate structure to easily release the fixing of the steel mesh, thus separating the device from the steel mesh. The entire disassembly process does not damage the device or the steel mesh, and the disassembled device can be reused in other construction scenarios. This not only reduces the difficulty and cost of engineering modifications but also improves the flexibility of engineering construction, making it particularly suitable for engineering scenarios that require phased adjustments or temporary reinforcement.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-4 A high-stability steel mesh anti-loosening connection device, the structure of which is as follows:

[0031] Rectangular shell 1

[0032] The rectangular shell 1 is the basic load-bearing structure of the entire high-stability steel mesh anti-loosening connection device. Most other components of the device are directly or indirectly installed inside or outside it. Internally, it has grooves 9 for accommodating and installing components such as the clamping plate structure and the lead screw 7. At the bottom, there is also a rectangular groove 8 for the lower end of the clamping plate structure to pass through and move. The bottom two sides of the rectangular shell 1 have integrally formed L-shaped bends 4, and its surface is also threaded with bolts 2 for fixing the entire device to the ground or the pre-threaded holes in the installation area. This provides a solid framework support for the stable operation of the entire device and the coordinated work of its components.

[0033] Bolt 2

[0034] Bolt 2 is threaded onto the rectangular housing 1, and its lower end can pass through the internal groove 9 inside the rectangular housing 1 and the bottom rectangular groove 8 at the bottom to extend to the bottom of the rectangular housing 1. After two adjacent steel mesh sheets are connected by the device, in order to further ensure the stability of the connection and prevent the overall device from shifting, bolt 2 can be used to fix the rectangular housing 1 in the ground or in the pre-set threaded holes in the area to be installed, thereby achieving reliable fixation of the entire connection device to the installation foundation and enhancing the overall anti-loosening ability of the device.

[0035] Knob 3

[0036] Knob 3 is fixedly installed at one end of the lead screw 7 extending to the outside of the rectangular housing 1. Its main function is to provide a convenient operating component for the operator to rotate the lead screw 7. Due to the setting of knob 3, the operator does not need to use additional tools. He can directly rotate knob 3 by hand to drive the lead screw 7 to rotate, thereby realizing the adjustment of the position of the clamping plate structure, which greatly simplifies the operation process and improves the efficiency of steel mesh connection and installation.

[0037] L-shaped bend 4

[0038] The L-shaped bend 4 is a mirror-molded structure on both sides of the bottom of the rectangular shell 1, with an L-shape and a specific opening. Its main function is to cooperate with the clamping plate structure to achieve initial positioning and clamping of the reinforcing mesh. When fixing two adjacent reinforcing meshes, the side reinforcing bars of the mesh are first aligned with the gap between the L-shaped bend 4 and the lower end of the clamping plate structure and inserted. Then, the mesh is pulled laterally to move the reinforcing bars to the bend of the L-shaped bend 4, preparing for further fixing of the reinforcing bars by the clamping plate structure. Its L-shaped design effectively restricts the movement of the reinforcing bars in a specific direction.

[0039] Bottom plate 5

[0040] The bottom clamping plate 5 is an important component of the clamping plate structure and is integrally formed with the top clamping plate 6. The upper end of the bottom clamping plate 5 is fixedly connected to the top clamping plate 6, while the lower end extends through the bottom rectangular groove 8 opened at the bottom of the rectangular shell 1 to the outside of the rectangular shell 1. During the operation of the device, the bottom clamping plate 5 can move laterally as the top clamping plate 6 slides in the inner groove 9. When the reinforcing bar of the steel mesh moves to the bend of the L-shaped bend 4, the position of the bottom clamping plate 5 is adjusted to seal the bend opening at the lower end of the L-shaped bend 4. At this time, the reinforcing bar of the steel mesh is restricted between the inner side of the bend of the L-shaped bend 4 and the bottom clamping plate 5, thereby fixing the reinforcing bar of the steel mesh and preventing the steel mesh from loosening.

[0041] Top snap-fit ​​plate 6

[0042] The top locking plate 6 is also a component of the locking plate structure, integrally formed with the bottom locking plate 5, and its entire assembly slides and locks into the internal groove 9 opened inside the rectangular shell 1. The top locking plate 6 not only provides mounting support for the bottom locking plate 5, allowing the bottom locking plate 5 to extend stably to the outside of the rectangular shell 1, but also has a threaded connection with the lead screw 7. The two ends of the lead screw 7 have different thread directions and are threadedly connected to the two top locking plates 6 respectively. When the lead screw 7 rotates, it will drive the two top locking plates 6 to move laterally in opposite directions, thereby driving the bottom locking plate 5 to move synchronously, realizing precise adjustment of the fixed position of the steel mesh. It is the key transmission component for the locking plate structure to achieve position adjustment.

[0043] Screw 7

[0044] The lead screw 7 is rotatably installed inside the rectangular housing 1. Its two ends have external threads with different thread directions, and both ends are threadedly connected to the two top locking plates 6. The lead screw 7 is the core transmission structure that drives the locking plate structure to move in a mirror image. When it is necessary to adjust the lateral position of the two top locking plates 6 and the bottom locking plate 5, rotating the lead screw 7 causes the two top locking plates 6 to move laterally in opposite directions along the internal groove 9 under the action of threaded transmission. This drives the bottom locking plate 5 to move synchronously in a mirror image, thereby adjusting the sealing position of the opening of the L-shaped bend 4 to accommodate the fixing requirements of different specifications of steel mesh. Furthermore, one end of the lead screw 7 extends to the outside of the rectangular housing 1 and is fixedly installed with a knob 3 for convenient rotation by the operator.

[0045] Bottom rectangular groove 8

[0046] A bottom rectangular groove 8 is formed at the bottom of the rectangular shell 1 and communicates with the internal groove 9. Its main function is to provide a moving channel and limit the movement of the bottom clamping plate 5. The bottom clamping plate 5 extends through the bottom rectangular groove 8 to the outside of the rectangular shell 1. Driven by the top clamping plate 6, the bottom clamping plate 5 can move laterally along the length of the bottom rectangular groove 8. At the same time, the shape and size of the bottom rectangular groove 8 limit the moving direction and range of the bottom clamping plate 5, ensuring that the bottom clamping plate 5 remains stable during movement and avoids displacement, thereby ensuring the reliability of fixing the steel mesh.

[0047] Internal slot 9

[0048] The internal groove 9, located inside the rectangular housing 1, serves as a crucial space for accommodating and installing components such as the top locking plate 6 and the lead screw 7. The top locking plate 6 is slidably engaged within the internal groove 9, which provides a stable track for its movement, ensuring smooth lateral movement. Simultaneously, the internal groove 9 also provides support space for the rotational installation of the lead screw 7, enabling it to rotate stably within the groove and achieve reliable threaded transmission with the top locking plate 6. This ensures the stable operation of the entire locking plate structure adjustment system and is a vital guarantee for the coordinated work of all transmission and adjustment components within the device.

[0049] The structure is connected as follows: It includes a rectangular shell 1, inside which are two sets of clamping plate structures that can be mirrored and moved to adjust their positions. The bottom two sides of the rectangular shell 1 are integrally formed with L-shaped bends 4. One side of the opening of the L-shaped bend 4 corresponds to the lower end of the clamping plate structure. When it is necessary to fix two adjacent steel meshes, the side steel bars of the steel mesh are aligned with the gap between the L-shaped bend 4 and the lower end of the clamping plate structure and inserted. Then, the steel mesh is pulled horizontally so that the steel bars of the steel mesh move to the bend of the L-shaped bend 4. Then, the position of the clamping plate structure is adjusted horizontally so that the lower end of the clamping plate structure blocks the bend opening at the lower end of the L-shaped bend 4. At this time, the steel bars of the steel mesh will be located between the inner side of the bend of the L-shaped bend 4 and the clamping plate structure, thus fixing the steel bars of the steel mesh. Then, the above steps are repeated for adjacent steel meshes to complete the connection and installation of two adjacent steel meshes.

[0050] Furthermore, an internal groove 9 is provided inside the rectangular housing 1, and a bottom rectangular groove 8 is provided at the bottom of the internal groove 9. The upper end of the clamping plate structure is slidably engaged inside the internal groove 9, and the lower end of the clamping plate structure extends to the outside of the rectangular housing 1 through the bottom rectangular groove 8.

[0051] Furthermore, two bolts 2 are threaded onto the rectangular shell 1. The lower ends of the two bolts 2 pass through the internal groove 9 and the bottom rectangular groove 8 and extend to the bottom of the rectangular shell 1. When two adjacent steel meshes are connected and it is necessary to fix the connected steel meshes, the rectangular shell 1 is fixed in the ground or in the pre-set threaded holes in the area to be installed using the bolts 2 to complete the overall installation. This device can achieve stable installation and is not easy to loosen.

[0052] Furthermore, the card plate structure consists of an integrally formed bottom card plate 5 and a top card plate 6. The top card plate 6 is slidably engaged inside the inner groove 9. The bottom card plate 5 is fixedly installed at the lower end of the top card plate 6. The bottom card plate 5 extends through the bottom rectangular groove 8 to the bottom of the rectangular housing 1.

[0053] Furthermore, a lead screw 7 is rotatably installed inside the rectangular housing 1. The two ends of the lead screw 7 are respectively provided with external threads in different directions. The two ends of the lead screw 7 are respectively threaded to the two top locking plates 6. When the two top locking plates 6 and the bottom locking plate 5 need to move laterally to adjust their positions, the lead screw 7 is rotated. Since the threads on both sides are in different directions, the two top locking plates 6 move laterally in opposite positions, thus realizing the mirror movement of the two top locking plates 6 and the bottom locking plate 5.

[0054] Furthermore, one end of the lead screw 7 extends to the outside of the rectangular housing 1, and a knob 3 is fixedly installed at the end of the lead screw 7 that extends to the outside of the rectangular housing 1. The addition of the knob 3 makes it easier to rotate the lead screw 7.

[0055] Working principle: When it is necessary to fix two adjacent steel mesh sheets, align the side steel bars of the steel mesh sheet with the gap between the L-shaped bend 4 and the lower end of the clamping plate structure and insert it. Then, pull the steel mesh sheet horizontally so that the steel bars of the steel mesh sheet move to the bend of the L-shaped bend 4. Then, adjust the position of the clamping plate structure horizontally so that the lower end of the clamping plate structure blocks the bend opening at the lower end of the L-shaped bend 4. At this time, the steel bars of the steel mesh sheet will be located between the inner side of the bend of the L-shaped bend 4 and the clamping plate structure, thus fixing the steel bars of the steel mesh sheet. Then, repeat the above steps for adjacent steel mesh sheets to complete the connection and installation of two adjacent steel mesh sheets.
