Abstract
Description
Technical Field
[0001] This utility model relates to the field of matting technology, and in particular to an overlapping matting. Background Technology
[0002] In modern engineering construction, emergency rescue, and military operations, interlocking paving mats, with their rapid assembly and flexible deployment, have become essential equipment for constructing temporary roads and work platforms. Whether in muddy, soft field terrain or complex mountainous environments, interlocking paving mats can quickly create passageways for vehicles and personnel, effectively ensuring project progress and mission efficiency, playing an irreplaceable role in various scenarios.
[0003] Existing interlocking mats primarily use snap-fit connections. These snap-fit structures typically feature protrusions and grooves along the edges of the mat. The protrusions engage with the grooves to achieve the connection, relying on the interlocking friction between the structures to maintain the connection and enable rapid assembly and basic fixation of the mats.
[0004] Existing overlapping paving mats, when subjected to continuous vibrations and heavy pressure from vehicle traffic, or when encountering external impacts, will gradually experience a decrease in the friction between the clips, leading to loosening of the clips, gaps or even separation between the paving mats, affecting traffic safety. Therefore, an overlapping paving mat is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an overlapping paving board, which aims to improve the problem that the existing paving boards are connected by snaps. When subjected to external impact, the friction between the snaps will gradually decrease, causing the snaps to loosen, gaps to appear between the paving boards or even separation, affecting traffic safety.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An overlapping paving board includes a paving board body, an overlapping plate fixedly connected to the bottom of the paving board body, a fixing component inside the paving board body, and a reinforcing component inside the overlapping plate.
[0008] The fixing component includes a ball bearing. An installation block one is fixedly connected inside the paving slab body. An installation block two is fixedly connected inside the paving slab. A fixing shell is slidably connected inside the installation block one. A threaded block is threadedly connected inside the fixing shell. A rotating handle is fixedly connected to the upper surface of the threaded block. A spring is fixedly connected to the lower surface of the threaded block. A compression block is fixedly connected to one end of the spring. The sidewall of the ball bearing is slidably connected inside the fixing shell.
[0009] As a further description of the above technical solution:
[0010] The reinforcing component includes reinforcing ribs, the sidewalls of which are fixedly connected to the inside of the mounting plate. The reinforcing ribs are in a cross-shaped interlacing pattern, which is used to effectively improve the stability of the overall structure and resist external forces and deformations in different directions.
[0011] As a further description of the above technical solution:
[0012] The side wall of the fixed shell is slidably connected inside the second mounting block, the side wall of the extrusion block is slidably connected inside the fixed shell, the side wall of the extrusion block is in contact with the side wall of the ball, and the side wall of the ball is slidably connected inside the second mounting block.
[0013] As a further description of the above technical solution:
[0014] The paving slab body is made of polycarbonate material, which is used to provide basic load-bearing capacity for the paving slab.
[0015] As a further description of the above technical solution:
[0016] The paving slab body has a reinforcing layer on its sidewall, which is made of aramid fiber and is used to enhance the paving slab body's tensile, tear and impact resistance.
[0017] As a further description of the above technical solution:
[0018] The reinforcing layer has a buffer layer on its sidewall. The buffer layer is made of rubber and is used to absorb vibration and impact, reducing damage to the paving slab body.
[0019] As a further description of the above technical solution:
[0020] The buffer layer has a wear-resistant layer on its sidewalls. The wear-resistant layer is made of ultra-high molecular weight polyethylene material and is used to protect the underlying structure from wear, corrosion and chemical damage, thereby improving the service life of the paving slab.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the mounting plate is connected to another paving plate, allowing the fixing shell to slide into the second mounting block of the other paving plate. Then, the rotating handle is turned, causing the threaded block to rotate inside the fixing shell. When the threaded block moves down, the spring is compressed, and the pressing block, under the elastic force of the spring, presses the ball downward, causing the ball to push outward and lock into the second mounting block of the other paving plate, thus completing the fixation. This solves the problem that some overlapping paving mats use snap-fit connections, and when subjected to external impact, the friction between the snaps gradually decreases, causing the snaps to loosen, resulting in gaps or even separation between the paving mats. The above structure improves the connection stability of the equipment.
[0023] 2. In this utility model, the cross-shaped reinforcing ribs provide support in two mutually perpendicular directions, evenly distributing the pressure from above and external forces from different directions to the entire paving slab, avoiding stress concentration. The aramid fibers of the reinforcing layer further enhance the tensile, tear, and impact resistance of the paving slab body. The buffer layer reduces damage to the paving slab body, and the wear-resistant layer protects the underlying structure from wear, corrosion, and chemical damage, extending the service life of the paving slab. Through the cooperation between the layers, the strength and durability of the paving slab body are guaranteed in various usage scenarios. Attached Figure Description

[0032] 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.
[0033] Reference Figures 1-5This utility model provides an embodiment of an overlapping paving slab, comprising a paving slab body 1, with an overlapping plate 2 fixedly connected to the bottom of the paving slab body 1. The overlapping plate 2 is used to connect with another paving slab, realizing the splicing of multiple paving slabs. A fixing component is provided inside the paving slab body 1 to ensure a stable connection between adjacent paving slabs and prevent loosening or displacement of the spliced paving slabs. A reinforcing component is provided inside the overlapping plate 2 to enhance the structural strength of the overlapping plate 2 and prevent deformation or damage during splicing and use.
[0034] The fixing component includes ball bearings 10, which securely engage with the mounting block 4 of another paving slab during the fixing process. Mounting block 3 is fixedly connected inside the paving slab body 1, and mounting block 4 is fixedly connected inside the paving slab 2. A fixing shell 5 is slidably connected inside mounting block 3, allowing it to slide horizontally with mounting block 3, facilitating docking with the mounting block 4 of the other paving slab. A threaded block 7 is threadedly connected inside the fixing shell 5, and a rotating handle 6 is fixedly connected to the upper surface of the threaded block 7. Rotating the rotating handle 6 allows the paving slab to be driven... The threaded block 7 rotates inside the fixed shell 5. A spring 8 is fixedly connected to the lower surface of the threaded block 7. A pressing block 9 is fixedly connected to one end of the spring 8. The spring 8 cooperates with the pressing block 9. When the threaded block 7 moves down, the spring 8 is compressed. Under the elastic force of the spring 8, the pressing block 9 presses the ball 10 downward. The side wall of the ball 10 is slidably connected to the inside of the fixed shell 5. The side wall of the fixed shell 5 is slidably connected to the inside of the second mounting block 4. The side wall of the pressing block 9 is slidably connected to the inside of the fixed shell 5. The side wall of the pressing block 9 fits against the side wall of the ball 10. The side wall of the ball 10 is slidably connected to the inside of the second mounting block 4.
[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6The reinforcing components include reinforcing ribs 11, which enhance the structural strength of the paving slab 2, effectively improving the overall structural stability and resisting external forces and deformations in different directions. The reinforcing ribs 11 are fixedly connected to the inside of the paving slab 2 in a cross-shaped interlocking configuration. This structural design disperses stress in both longitudinal and transverse directions, allowing the paving slab 2 to maintain good structural integrity even under complex external forces such as lateral compression and longitudinal tension. The paving slab body 1 is made of polycarbonate, a high-performance engineering plastic with good toughness and impact resistance, providing basic load-bearing capacity for the paving slab. A reinforcing layer 12 is provided on the sidewall of the paving slab body 1, made of aramid fiber. Aramid fiber has high strength and high modulus, enhancing the tensile, tear, and impact resistance of the paving slab body 1. The reinforcing layer 12, in conjunction with the paving slab body 1, further improves the durability of the paving slab under heavy loads and scratches from sharp objects, extending its service life. The wall is provided with a buffer layer 13, which is made of rubber. Rubber has good elasticity and is used to absorb vibration and impact, reducing damage to the paving slab body 1. The buffer layer 13 works with the reinforcement layer 12. When the paving slab is subjected to vibration from vehicles or impact from falling heavy objects, the buffer layer 13 first absorbs the energy and converts it into its own deformation, thereby reducing the impact of the impact on the reinforcement layer 12 and the paving slab body 1. This achieves the effect of protecting the internal structure and improving stability. The side wall of the buffer layer 13 is provided with a wear-resistant layer 14, which is made of ultra-high molecular weight polyethylene. Ultra-high molecular weight polyethylene has excellent wear resistance and corrosion resistance. It is used to protect the underlying structure from wear, corrosion and chemical damage, and improve the service life of the paving slab. In actual use, the wear-resistant layer 14 directly comes into contact with the ground, wheels and other friction, preventing sand, oil and other substances from damaging the buffer layer 13 and the internal structure. This achieves the effect of all-round protection and improving the overall performance.
[0036] Working principle: When two paving slabs need to be overlapped, the overlapping plate 2 at the bottom of the paving slab body 1 aligns with the other paving slab. Then, the fixing shell 5 slides into the mounting block 4 of the other paving slab. At this time, turning the handle 6 causes the threaded block 7, which is threadedly connected to the fixing shell 5, to rotate inside the fixing shell 5. Due to the threaded transmission principle, the threaded block 7 will move downward along the axial direction of the fixing shell 5. During the downward movement of the threaded block 7, the spring 8 is compressed, and the elastic force generated by the spring 8 acts on the pressing block 9, causing the pressing block 9 to... The lower compression ball 10 is pushed outward under the compression force and engages inside the mounting block 4 of the other paving slab, thus fixing the two paving slabs. When disassembly is required, the handle 6 is rotated in the opposite direction, the threaded block 7 moves upward, the spring 8 relaxes, the compression block 9 moves upward, the ball 10 loses compression, and the two paving slabs can be easily separated. The reinforcing ribs 11 set inside the paving slab 2 provide support in two mutually perpendicular directions. When the paving slab is subjected to different forces... Under pressure, tension, or impact, the reinforcing ribs 11 can evenly distribute these external forces across the entire paving slab 2, effectively preventing stress concentration and significantly improving the overall stability of the paving slab structure, enhancing its resistance to deformation. The paving slab body 1 is made of polycarbonate, providing basic load-bearing capacity. The reinforcing layer 12 on the sidewall of the paving slab body 1 is made of aramid fiber, further enhancing the tensile, tear, and impact resistance of the paving slab body 1. The buffer layer 13 outside the reinforcing layer 12 is made of rubber, effectively absorbing vibrations and impacts generated during vehicle operation, reducing damage to the paving slab body 1. The outermost wear-resistant layer 14 is formed by spraying ultra-high molecular weight polyethylene material, effectively protecting the underlying structure from wear, corrosion, and chemical damage, greatly improving the service life of the paving slab. The materials of each layer work together to comprehensively improve the strength and durability of the paving slab in various usage scenarios, from load-bearing, reinforcement, buffering to protection.
