Description

Technical Field

[0001] This utility model relates to the field of steel mesh installation, specifically a high-precision steel mesh rapid splicing device. Background Technology

[0002] In the construction of infrastructure such as buildings, transportation, and water conservancy, steel mesh is widely used as an important reinforcing material for reinforced concrete structures in construction scenarios such as floor slabs, roads, bridges, and tunnel linings. Steel mesh is composed of multiple transverse and longitudinal steel bars welded or tied at preset intervals. It effectively improves the tensile strength, crack resistance, and overall stability of concrete structures, reduces the amount of on-site steel bar tying work during construction, and shortens the construction period. Therefore, its demand in modern engineering construction is increasing.

[0003] However, steel mesh faces a key problem in practical applications: due to limitations in production equipment, transportation conditions, and the size of construction sites, the size of a single steel mesh sheet is usually fixed, making it impossible to directly meet the needs of large-scale projects for ultra-large steel mesh sheets. For example, in highway pavement construction, the pavement width can reach over 20 meters, while conventionally produced steel mesh sheets are mostly 2-4 meters wide; in the construction of large factory floor slabs, the floor area often exceeds several hundred square meters, and the coverage of a single steel mesh sheet is far from meeting the construction requirements. Therefore, in actual construction, multiple steel mesh sheets must be laid adjacent to each other in a plane and connected into a complete and continuous steel mesh structure through effective splicing methods to ensure the smooth progress of subsequent concrete pouring and the achievement of the final structural mechanical performance standards.

[0004] Currently, the industry mainly uses two methods for splicing steel mesh: traditional binding and welding. Binding involves tying the intersecting steel bars of adjacent steel mesh sections together with wire. While this method is simple to operate and requires no specialized equipment, it has significant drawbacks: Firstly, the strength of the binding depends on the operator's skill level; uneven binding force can easily lead to loosening of the joints, causing displacement of the steel mesh during subsequent concrete pouring and vibration, affecting structural accuracy. Secondly, binding operations are extremely inefficient, requiring a large investment of manpower and time for large-scale construction projects, severely hindering construction progress.

[0005] Welded connections, using methods such as arc welding and resistance welding, join the ends or intersections of adjacent steel mesh reinforcement bars together. Compared to lapped connections, they offer higher strength and better stability. However, welded connections also present several challenges: First, the welding process requires specialized welders and equipment, resulting in higher construction costs and demanding environmental conditions; in humid or windy environments, weld quality is difficult to guarantee. Second, welding generates high temperatures, which can lead to a decrease in the local mechanical properties of the reinforcement bars, resulting in hardened structures, increased brittleness, and potential safety hazards. Furthermore, welding is relatively slow, and post-weld inspection and treatment of the weld seams further increase construction procedures and time costs, failing to meet the demands of modern engineering for efficient construction.

[0006] In addition to the two mainstream methods mentioned above, some projects have also tried mechanical connection methods such as bolt connection. However, traditional bolt connection structure is complex and requires pre-drilling holes in the steel bars, which not only weakens the cross-sectional area of ​​the steel bars and affects their load-bearing capacity, but also requires aligning the bolt holes and tightening the bolts one by one during the installation process. The operation is cumbersome and the splicing efficiency is still low, making it difficult to meet the requirements of large-scale and rapid construction.

[0007] In summary, existing steel mesh splicing methods generally suffer from problems such as low splicing efficiency, poor connection stability, high requirements for construction environment and personnel skills, and easy impact on steel performance. They can no longer meet the current demand for efficient, high-precision, and high-quality steel mesh splicing in the field of infrastructure construction. Therefore, we propose a high-precision steel mesh rapid splicing device. Utility Model Content

[0008] To address the shortcomings of existing technologies, this invention provides a high-precision rapid splicing device for steel mesh, which solves the aforementioned problems.

[0009] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a high-precision steel mesh rapid splicing device, including a top cover plate, two mirrored arc-shaped plates fixedly installed at the bottom of the top cover plate, two arc-shaped plug-in blocks that can retract into the top cover plate respectively on both sides of the bottom of the top cover plate, and a pin assembly provided at the lower end of the arc plate for fixing the arc-shaped plug-in blocks.

[0010] Preferably, the top cover plate has an arc-shaped groove corresponding to the arc-shaped plug-in block inside, and a strip-shaped opening is provided at the bottom of the top cover plate corresponding to the arc-shaped groove. One end of the arc-shaped plug-in block extends into the arc-shaped groove through the strip-shaped opening.

[0011] Preferably, a limiting block is fixedly installed at one end of the arc-shaped plug block inside the arc-shaped groove, and the limiting block is in contact with the inner wall of the arc-shaped groove.

[0012] Preferably, the bottom of the arc-shaped plug block is provided with a slot, and when the end of the arc-shaped plug block is in contact with the end of the arc-shaped plate, the plug end of the plug assembly is engaged with the slot.

[0013] Preferably, the pin assembly includes a bottom strip protrusion integrally formed on the lower end of the arc plate and a pin plate disposed inside the bottom strip protrusion. A through rectangular groove is provided on the bottom strip protrusion, and the pin plate is inserted into the rectangular groove.

[0014] Preferably, inner wall grooves are respectively formed on the inner walls of both sides of the rectangular groove, and a side rectangular protrusion is integrally formed at the position of the pin plate corresponding to the inner wall groove. The side rectangular protrusion is movably engaged with the inner wall groove.

[0015] Preferably, multiple sets of springs are installed at equal intervals on the bottom inner wall of the inner wall groove. The upper end of the spring is in contact with the side rectangular protrusion. When the spring rebounds normally, it will squeeze the side rectangular protrusion, thus allowing the upper end of the pin plate to pass through the rectangular groove and extend to the top outer side of the bottom strip protrusion.

[0016] Compared with the prior art, this utility model provides a high-precision rapid splicing device for steel mesh, which has the following beneficial effects:

[0017] Significantly improves splicing efficiency and shortens construction period

[0018] This device completely revolutionizes the inefficient traditional method of manual, one-by-one binding connections and the need for specialized equipment and complex procedures in welding connections. During the splicing process, the curved connector block is simply retracted into the top cover plate, the reinforcing bars of adjacent steel mesh are placed in the concave area of ​​the curved plate, and then the curved connector block is slid downwards to align with the end of the curved plate. Finally, the spring return of the pin assembly automatically locks the connection in place. The entire operation requires no complex tools and can be completed quickly by a single person. Compared to traditional binding connections, this method is 3-5 times more efficient, and compared to welding connections, it is 2-3 times more efficient. For large-scale construction projects, it significantly reduces manpower and working time, effectively shortening the overall construction period and meeting the demands of modern engineering for efficient construction.

[0019] Ensure connection stability and structural precision, and reduce safety hazards.

[0020] The device uses an arc-shaped plate and an arc-shaped plug to form a semi-circular receiving area, which can tightly wrap the reinforcing steel section of the steel mesh. Combined with the locking structure of the pin assembly, it forms a stable and reliable connection node, avoiding the loosening problem caused by uneven manual force in traditional binding connections. Simultaneously, the pin assembly achieves automatic locking with the elastic force of a spring, providing uniform and durable locking force. During subsequent concrete pouring and vibration, it effectively prevents displacement of the steel mesh, ensuring that the overall steel mesh structure after splicing meets design requirements. Furthermore, this device eliminates the need for welding, avoiding the damage to the local mechanical properties of the reinforcing steel caused by high temperatures and preventing the formation of hardened structures. This fundamentally eliminates safety hazards caused by increased brittleness of the reinforcing steel, ensuring the long-term mechanical performance and service safety of reinforced concrete structures.

[0021] Simple and easy to operate, reducing construction threshold and cost.

[0022] The device features a simple overall structural design, and the assembly process requires no specialized technicians. Ordinary construction workers can master it after simple training, completely solving the problems of high dependence on professional welders and high construction barriers associated with traditional welding connections. Furthermore, the device eliminates the need for complex equipment such as welding machines and bolt drilling equipment, reducing investment and maintenance costs. It also eliminates the need for consumables such as wire and welding rods during assembly, further reducing material costs. In addition, its ease of operation and high assembly efficiency reduce the number of on-site personnel, lowering labor costs and saving expenses for the project from multiple dimensions.

[0023] It does not damage the properties of the steel reinforcement and extends the service life of the structure.

[0024] Unlike traditional bolted connections, which require pre-drilling holes in the reinforcing bars, resulting in a weakening of the cross-sectional area and a decrease in load-bearing capacity, this device uses an enveloping fixing method with an arc-shaped plate and an arc-shaped plug block. This eliminates the need for any processing of the reinforcing bars, fully preserving their original cross-sectional dimensions and mechanical properties. This ensures that the reinforcing bars can fully exert their tensile and compressive strengths during subsequent use, avoiding the problem of reduced structural load-bearing capacity caused by reinforcing bar damage. Consequently, it extends the overall service life of reinforced concrete structures and reduces later maintenance and reinforcement costs.

[0025] Adaptable to various construction environments, enhancing construction flexibility

[0026] Traditional welding connections are significantly affected by harsh environments such as humidity and strong winds, easily leading to substandard welding quality. In contrast, this device's splicing process is independent of specific environmental conditions. Whether in open-air bridge construction, damp tunnel lining construction, or complex factory floor slab construction, it can reliably perform splicing functions, unaffected by environmental factors. Furthermore, the device can match appropriately sized curved plates and curved connectors to the diameter of different specifications of steel mesh, accommodating the splicing needs of various types of steel mesh, improving the flexibility and applicability of the construction process, and meeting the splicing requirements of different engineering scenarios.

[0033] 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.

[0034] Please see Figure 1-5 A high-precision steel mesh rapid splicing device, the structure of which is as follows:

[0035] Top cover 1

[0036] The top cover plate 1 is the basic load-bearing structure of the entire high-precision rebar mesh rapid splicing device, providing an installation and support platform for other components. Two mirror-shaped arc-shaped plates 2 are fixedly installed at its bottom. These two arc-shaped plates 2 are key components for the initial contact and positioning of the device with the rebar section of the rebar mesh. Simultaneously, at the bottom of the top cover plate 1, corresponding to the two sides of the two arc-shaped plates 2, two arc-shaped insertion blocks 4 are respectively provided that can retract into the top cover plate 1. The arc-shaped insertion blocks 4 can be extended and retracted through specific operations to cooperate with the arc-shaped plates 2 in wrapping and fixing the rebar mesh. Furthermore, an arc-shaped groove 3 is formed inside the top cover plate 1 corresponding to the position of the arc-shaped insertion blocks 4, and a strip-shaped opening is formed at the bottom corresponding to the position of the arc-shaped groove 3. This strip-shaped opening provides a channel for the extension and retraction of the arc-shaped insertion blocks 4, allowing one end of the arc-shaped insertion block 4 to extend into the arc-shaped groove 3 through the strip-shaped opening, thus realizing the retraction and extension of the arc-shaped insertion blocks 4 inside the top cover plate 1.

[0037] Curved plate 2

[0038] Two arc-shaped plates 2 are fixedly installed at the bottom of the top cover plate 1 in a mirror manner. They are important structures in the device for initially accommodating and positioning the reinforcing bars of the steel mesh. The shape of the arc-shaped plates 2 is adapted to the shape of the reinforcing bars, and their opposite sides form a concave area. This concave area can fit against the reinforcing bars of two adjacent steel meshes, providing a stable placement space for the reinforcing bars in the initial stage of splicing. A pin assembly is provided at the lower end of the arc-shaped plate 2. The core function of the pin assembly is to fix the arc-shaped plug block 4. When the arc-shaped plug block 4 slides down until its end fits against the lower end of the arc-shaped plate 2, the locking function of the pin assembly ensures that the arc-shaped plug block 4 and the arc-shaped plate 2 form a stable accommodating area, thereby fixing the steel mesh. In addition, the lower end of the arc-shaped plate 2 has an integrally formed bottom strip protrusion 6. The bottom strip protrusion 6 is an important mounting carrier for the pin assembly, providing an installation base for components such as the pin plate 8.

[0039] Arc groove 3

[0040] The arc-shaped groove 3 is formed inside the top cover plate 1, and its position corresponds to the arc-shaped plug-in block 4. It is a structure specifically designed to provide storage and movement space for the arc-shaped plug-in block 4. The shape and size of the arc-shaped groove 3 match the arc-shaped plug-in block 4, allowing the arc-shaped plug-in block 4 to slide smoothly inside the arc-shaped groove 3, retracting into or extending out of the top cover plate 1. At the same time, the inner wall of the arc-shaped groove 3 is in close contact with the limiting block 5 fixedly installed at one end of the arc-shaped plug-in block 4. The limiting block 5 moves under the constraint of the inner wall of the arc-shaped groove 3, which can effectively prevent the arc-shaped plug-in block 4 from shifting or detaching from the arc-shaped groove 3 during sliding, ensuring the stability and reliability of the movement of the arc-shaped plug-in block 4, and thus ensuring the smooth operation of the entire splicing device.

[0041] Arc-shaped connector 4

[0042] There are two arc-shaped plug-in blocks 4, respectively located on the bottom of the top cover plate 1 on both sides of the two arc-shaped plates 2. One end of each block extends into the arc-shaped groove 3 through a strip opening at the bottom of the top cover plate 1, and can retract into the top cover plate 1 or slide downwards within the arc-shaped groove 3. The core function of the arc-shaped plug-in block 4 is to cooperate with the arc-shaped plates 2 to form an area for accommodating the reinforcing bars of the steel mesh. When it is necessary to fix two adjacent steel meshes, the arc-shaped plug-in block 4 is first retracted into the top cover plate 1. After the reinforcing bars are placed in the concave area of ​​the arc-shaped plates 2, the arc-shaped plug-in block 4 is slid downwards so that its end fits against the lower end of the arc-shaped plates 2. At this time, the two form an area with a semi-circular cross-section, which can tightly wrap the reinforcing bars and provide a foundation for fixing the steel mesh. Furthermore, a slot 12 is provided at the bottom of the arc-shaped plug-in block 4. When the end of the arc-shaped plug-in block 4 is in contact with the end of the arc-shaped plate 2, the slot 12 corresponds to the position of the pin plate 8 in the pin assembly. The pin plate 8 can be inserted into the slot 12 to lock and fix the arc-shaped plug-in block 4, thereby ensuring the stability of the receiving area and completing the splicing of the steel mesh. At the same time, a limiting block 5 is fixedly installed at one end of the arc-shaped plug-in block 4 located inside the arc-shaped groove 3. The limiting block 5 is in contact with the inner wall of the arc-shaped groove 3, which can prevent the arc-shaped plug-in block 4 from disengaging from the arc-shaped groove 3 during sliding, ensuring the stability of its movement trajectory.

[0043] Limit block 5

[0044] The limiting block 5 is fixedly installed at one end of the arc-shaped plug-in block 4 located inside the arc-shaped groove 3. It is a key structure to ensure the stable sliding of the arc-shaped plug-in block 4 within the arc-shaped groove 3. The shape of the limiting block 5 is adapted to the inner wall of the arc-shaped groove 3, and it always remains in contact with the inner wall of the arc-shaped groove 3. When it is necessary to install the steel mesh, the arc-shaped plug-in block 4 is pressed into the arc-shaped groove 3. The limiting block 5 will move synchronously along the inner wall of the arc-shaped groove 3. During the movement, the inner wall of the arc-shaped groove 3 constrains and guides the limiting block 5, which can effectively prevent the arc-shaped plug-in block 4 from shifting, shaking, or even falling out of the arc-shaped groove 3 during the contraction or extension. This ensures that the arc-shaped plug-in block 4 can complete the extension and retraction movements accurately and stably, thereby ensuring the smooth operation of subsequent operations such as forming a receiving area with the arc-shaped plate 2 and locking and fixing the plug assembly, and improving the reliability and operational accuracy of the entire splicing device.

[0045] Bottom strip protrusion 6

[0046] The bottom strip-shaped protrusion 6 is integrally formed at the lower end of the arc-shaped plate 2, serving as an important mounting base for the pin assembly and providing a stable mounting platform for components such as the pin plate 8. The structural design of the bottom strip-shaped protrusion 6 must meet the installation and operational requirements of the pin assembly. It features a through rectangular groove 7, which provides installation and movement space for the pin plate 8. The pin plate 8 can move up and down within the rectangular groove 7, thereby locking and unlocking the arc-shaped connector block 4. The integral design of the bottom strip-shaped protrusion 6 with the arc-shaped plate 2 ensures a firm connection between the two, thus ensuring the stable operation of the pin assembly and preventing failure due to an unstable mounting base, which could affect the overall fixing effect of the splicing device on the reinforcing mesh.

[0047] Rectangular slot 7

[0048] A rectangular groove 7 is formed inside the bottom strip-shaped protrusion 6 and extends through it, specifically designed to provide installation and movement space for the pin plate 8. The dimensions of the rectangular groove 7 match the pin plate 8, allowing the pin plate 8 to be smoothly inserted into the rectangular groove 7 and slide up and down within it. Simultaneously, inner wall grooves 9 are formed on the inner walls of both sides of the rectangular groove 7. These inner wall grooves 9 provide installation and movement space for the side rectangular protrusions 10 on the pin plate 8. The side rectangular protrusions 10 are movably engaged with the inner wall grooves 9. This engagement not only guides the movement of the pin plate 8, preventing it from shifting left or right during sliding, but also limits its range of movement, preventing it from detaching from the rectangular groove 7. In addition, multiple sets of springs 11 are installed at equal intervals on the bottom inner wall of the inner wall groove 9. The springs 11 provide power for the automatic rebound of the pin plate 8. When the pin plate 8 is pulled down and released, the springs 11 can push the pin plate 8 to move upward, so as to realize the automatic locking of the pin plate 8 to the arc-shaped plug block 4, thereby improving the convenience of operation.

[0049] Plug plate 8

[0050] The pin plate 8 is the core actuator of the pin assembly. It is inserted into the rectangular groove 7 inside the bottom strip protrusion 6 and can move up and down within the rectangular groove 7. Its main function is to lock and fix the arc-shaped plug block 4 by cooperating with the slot 12 at the bottom of the arc-shaped plug block 4. The pin plate 8 has an integrally formed side rectangular protrusion 10 at the position of the inner wall groove 9 on both sides of the rectangular groove 7. The side rectangular protrusion 10 is movably engaged with the inner wall groove 9. On the one hand, it guides the movement of the pin plate 8 to ensure that the pin plate 8 slides up and down along a fixed trajectory. On the other hand, it prevents the pin plate 8 from disengaging from the rectangular groove 7 during movement, ensuring the stability of the pin plate 8 during operation. When the arc-shaped plug block 4 needs to be fixed, pull down the pin plate 8. At this time, the rectangular protrusion 10 on the side will compress the spring 11 at the bottom of the inner wall groove 9, causing the spring 11 to contract and one end of the pin plate 8 to retract into the rectangular groove 7. When the end of the arc-shaped plug block 4 is in contact with the end of the arc-shaped plate 2, and the slot 12 corresponds to the position of the pin plate 8, release the pin plate 8. The spring 11 will rebound, pushing the rectangular protrusion 10 on the side to move upward, thereby driving the pin plate 8 to move upward, so that the upper end of the pin plate 8 passes through the rectangular groove 7 and is inserted into the slot 12, completing the locking and fixing of the arc-shaped plug block 4. In the normal rebound state of the spring 11, the spring 11 will compress the rectangular protrusion 10 on the side, so that the upper end of the pin plate 8 passes through the rectangular groove 7 and extends to the top outside of the bottom strip protrusion 6, preparing for the subsequent locking operation.

[0051] Inner wall groove 9

[0052] The inner wall grooves 9 are respectively formed on the inner walls of the rectangular groove 7 on both sides. They provide installation and movement space for the side rectangular protrusions 10 of the pin plate 8 and provide an installation position for the spring 11. The shape and size of the inner wall grooves 9 are adapted to the side rectangular protrusions 10, ensuring that the side rectangular protrusions 10 can move smoothly in the groove. At the same time, they constrain and guide the side rectangular protrusions 10, thereby ensuring that the pin plate 8 slides stably up and down in the rectangular groove 7 and avoiding displacement. Multiple sets of springs 11 are equidistantly installed on the bottom inner wall of the inner wall groove 9. The upper end of the spring 11 is in contact with the side rectangular protrusion 10. In its natural state, the spring 11 has an upward elastic force, which can push the side rectangular protrusion 10 to move upward, thereby causing the pin plate 8 to extend upward. When the pin plate 8 is pulled downward, the side rectangular protrusion 10 will compress the spring 11, so that the spring 11 stores elastic potential energy. After the pin plate 8 is released, the spring 11 releases the elastic potential energy, pushing the side rectangular protrusion 10 and the pin plate 8 to reset, realizing the automatic locking of the pin plate 8 to the arc-shaped plug block 4. The existence of the inner wall groove 9 provides the necessary conditions for the installation of the spring 11 and the exercise of its elastic function.

[0053] 10 rectangular protrusions on the side

[0054] The rectangular protrusion 10 on the side is integrally formed at the position of the inner wall groove 9 corresponding to the pin plate 8. It is movably engaged with the inner wall groove 9 and is the key structure that connects the pin plate 8 and the inner wall groove 9 and works with the spring 11 to realize the up and down movement of the pin plate 8. The rectangular protrusion 10 on the side matches the shape of the inner wall groove 9, allowing it to slide smoothly within the inner wall groove 9. Its main functions are, firstly, to guide and limit the movement of the pin plate 8, ensuring that the pin plate 8 always moves up and down along the trajectory of the inner wall groove 9, preventing the pin plate 8 from shifting left or right or rotating within the rectangular groove 7, and ensuring the stability of the pin plate 8's movement; secondly, the rectangular protrusion 10 on the side is in contact with the upper end of the spring 11 at the bottom of the inner wall groove 9. When the spring 11 extends or retracts, it directly acts on the rectangular protrusion 10 on the side, thereby driving the pin plate 8 to move synchronously, realizing the extension and retraction of the pin plate 8, thus completing the locking and unlocking action of the arc-shaped plug block 4. The presence of the rectangular protrusion 10 on the side allows the pin plate 8 to cooperate effectively with the spring 11, ensuring the normal functioning of the pin assembly.

[0055] Spring 11

[0056] Multiple sets of springs 11 are equidistantly installed on the bottom inner wall of the inner wall groove 9. Their upper ends abut against the side rectangular protrusions 10, serving as the core component providing elastic driving force for the pin plate 8. In its normal rebound state, the springs 11 generate an upward elastic force that compresses the side rectangular protrusions 10, thereby pushing the pin plate 8 upward. This causes the upper end of the pin plate 8 to pass through the rectangular groove 7 and extend to the top outer side of the bottom strip protrusion 6, at which point the pin plate 8 is in a locked state. When it is necessary to fix the arc-shaped plug block 4, the pin plate 8 is pulled downward. The pin plate 8 causes the side rectangular protrusions 10 to move downward, compressing the springs 11, causing the springs 11 to contract and store elastic potential energy. At this time, one end of the pin plate 8 retracts into the rectangular groove 7, providing space for the arc-shaped plug block 4 to move downward and fit. When the end of the arc-shaped connector 4 is in contact with the end of the arc-shaped plate 2, and the slot 12 corresponds to the pin plate 8, the pin plate 8 is released. The spring 11 releases its stored elastic potential energy, quickly rebounds, and pushes the side rectangular protrusion 10 upward. The side rectangular protrusion 10 drives the pin plate 8 upward, allowing the pin plate 8 to be smoothly inserted into the slot 12, thus completing the locking and fixing of the arc-shaped connector 4. The elasticity of the spring 11 ensures that the pin plate 8 can automatically and quickly complete the locking action, improving the ease of operation and work efficiency of the entire splicing device.

[0057] Slot 12

[0058] The slot 12, located at the bottom of the arc-shaped plug-in block 4, is a key structure that works with the pin plate 8 to lock and fix the arc-shaped plug-in block 4. The position and dimensions of the slot 12 are precisely designed so that when the end of the arc-shaped plug-in block 4 is aligned with the end of the arc-shaped plate 2, the slot 12 accurately corresponds to the position of the pin plate 8, providing precise positioning for the insertion of the pin plate 8. During the splicing operation, after the arc-shaped plug-in block 4 and the arc-shaped plate 2 form a semi-circular area to accommodate the reinforcing bars, the pin plate 8 moves upward under the rebound of the spring 11 and inserts into the slot 12. At this point, the pin plate 8 and the slot 12 are tightly engaged, effectively restricting the movement of the arc-shaped plug-in block 4 and preventing it from loosening or shifting during subsequent use. This ensures that the area formed by the arc-shaped plug-in block 4 and the arc-shaped plate 2 remains stable, firmly fixing the reinforcing bars of the steel mesh and ensuring the reliability of the connection between adjacent steel meshes, achieving a high-quality splicing effect.

[0059] The structure is connected as follows: It includes a top cover plate 1. Two mirrored arc-shaped plates 2 are fixedly installed at the bottom of the top cover plate 1. Two arc-shaped insertion blocks 4, retractable into the top cover plate 1, are respectively provided on both sides of the two arc-shaped plates 2 at the bottom of the top cover plate 1. A pin assembly is provided at the lower end of the arc-shaped plates 2 to fix the arc-shaped insertion blocks 4. When it is necessary to fix two adjacent steel meshes, the arc-shaped insertion blocks 4 are retracted into the top cover plate 1. Then, the steel reinforcement sections of the two adjacent steel meshes are moved to the concave areas on opposite sides of the two arc-shaped plates 2. Finally, the arc-shaped insertion blocks are slid downwards. Block 4 is used to make the end of the arc-shaped plug-in block 4 fit with the lower end of the arc-shaped plate 2. At this time, the arc-shaped plug-in block 4 and the arc-shaped plate 2 will form a receiving area with a semi-circular cross-section. Then, the arc-shaped plug-in block 4 is fixed by the plug assembly to complete the connection of two adjacent steel mesh sheets and realize splicing. Since the size of the steel mesh sheet is constant after production, multiple steel mesh sheets need to be laid adjacent to each other in different application scenarios. Therefore, it is necessary to connect two adjacent steel mesh sheets to form a whole steel mesh sheet. By adding this device, two adjacent steel mesh sheets can be quickly and stably connected.

[0060] Furthermore, an arc-shaped groove 3 is provided inside the top cover plate 1 corresponding to the arc-shaped plug 4, and a strip-shaped opening is provided at the bottom of the top cover plate 1 corresponding to the arc-shaped groove 3. One end of the arc-shaped plug 4 extends into the interior of the arc-shaped groove 3 through the strip-shaped opening.

[0061] Furthermore, a limiting block 5 is fixedly installed at one end of the arc-shaped plug block 4 inside the arc-shaped groove 3. The limiting block 5 is in contact with the inner wall of the arc-shaped groove 3. When it is necessary to install the steel mesh, the arc-shaped plug block 4 is pressed into the arc-shaped groove 3. At this time, the limiting block 5 moves along the inner wall of the arc-shaped groove 3, and the arc-shaped plug block 4 gradually retracts into the arc-shaped groove 3.

[0062] Furthermore, a slot 12 is provided at the bottom of the arc-shaped plug block 4. When the end of the arc-shaped plug block 4 is in contact with the end of the arc-shaped plate 2, the plug end of the plug assembly is engaged with the slot 12.

[0063] Furthermore, the pin assembly includes a bottom strip protrusion 6 integrally formed on the lower end of the arc plate 2 and a pin plate 8 disposed inside the bottom strip protrusion 6. A through rectangular groove 7 is provided on the bottom strip protrusion 6, and the pin plate 8 is inserted into the rectangular groove 7.

[0064] Furthermore, inner wall grooves 9 are respectively provided on the inner walls of both sides of the rectangular groove 7, and a side rectangular protrusion 10 is integrally formed on the pin plate 8 at the position corresponding to the inner wall groove 9. The side rectangular protrusion 10 is movably engaged with the inner wall groove 9.

[0065] Furthermore, multiple sets of springs 11 are equidistantly installed on the bottom inner wall of the inner wall groove 9. The upper end of the spring 11 is in contact with the side rectangular protrusion 10. When the spring 11 rebounds normally, it will squeeze the side rectangular protrusion 10, thus allowing the upper end of the pin plate 8 to pass through the rectangular groove 7 and extend to the top outer side of the bottom strip protrusion 6. When it is necessary to fix the arc-shaped plug block 4, the steel bar part of the steel mesh is moved to the concave area of ​​the arc plate 2, and then the pin plate 8 is pulled down. At this time, the spring 11 retracts, and then one end of the pin plate 8 retracts into the interior of the rectangular groove 7. Then the end of the arc-shaped plug block 4 is in contact with the end of the arc plate 2. At this time, the position of the slot 12 corresponds to the position of the pin plate 8. When the pin plate 8 is released, the spring 11 rebounds, and then the pin plate 8 is inserted into the interior of the slot 12 to complete the locking and fixing.

[0066] Working principle: When it is necessary to fix two adjacent steel mesh sheets, the arc-shaped plug block 4 is retracted into the top cover plate 1. Then, the steel bars of the two adjacent steel mesh sheets are moved to the concave areas on opposite sides of the two arc plates 2. Then, the arc-shaped plug block 4 is slid down so that the end of the arc-shaped plug block 4 fits with the lower end of the arc plate 2. At this time, the arc-shaped plug block 4 and the arc plate 2 will form a receiving area with a semi-circular cross-section. Then, the pin assembly is used to fix the arc-shaped plug block 4, completing the connection of the two adjacent steel mesh sheets and realizing splicing.
