[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 A lightweight composite material rapid paving slab in this embodiment includes a composite board 1, both side walls of the composite board 1 are installed with plug-in boards 2, and both side walls of the composite board 1 away from the plug-in boards 2 are installed with connecting boards 3.

[0023] The composite board 1 is made of a polymer composite material, which has the properties of wear resistance, acid and alkali resistance, and load-bearing resistance, and can withstand the use requirements in different environments. The paving board made of the composite material is light in weight, easy to carry, and environmentally friendly. The polyethylene material used is a non-toxic and harmless food-grade material and is environmentally friendly.

[0024] It should be noted that the surface of the composite board 1 has anti-skid patterns, which can increase the anti-skid property of the paving board and provide better grip for vehicles and equipment when they are working.

[0025] A plug-in block 21 is fixedly connected to one side of the plug-in board 2, an installation cavity 22 is provided inside the plug-in block 21, a movable block 24 is slidably connected inside the installation cavity 22, a limit block 25 is fixedly connected to one side of the movable block 24, and a telescopic spring 23 is fixedly installed on the side of the movable block 24 away from the limit block 25.

[0026] It should be noted that by aligning the connecting plate 3 on the composite board 1 with the plug-in plate 2 on the adjacent composite board 1 so that the plug-in block 21 is snapped into the inside of the slot 31, the limit block 25 will be squeezed to move into the inside of the installation cavity 22, thereby causing the telescopic spring 23 to expand and contract. When the limit block 25 is aligned with the limit groove 32, the rebound force of the telescopic spring 23 will cause the limit block 25 to be inserted into the inside of the limit groove 32, thereby locking the plug-in plate 2 and the connecting plate 3 together. The operations can be performed in sequence to quickly splice multiple paving boards, and the operation is simple.

[0027] A slot 31 is provided on one side of the connecting plate 3, and a limiting slot 32 is provided on the inner side wall of the slot 31. The slot 31 is adapted to the plug-in block 21, and the limiting block 25 is adapted to the limiting slot 32. A pull rod 26 is fixedly connected to the front surface of the movable block 24. A sliding hole 29 connected to the installation cavity 22 is provided inside the plug-in block 21, and the pull rod 26 is slidably connected to the inside of the sliding hole 29. A groove 28 is provided on one side of the plug-in block 21, and the sliding hole 29 is located inside the groove 28. A cover plate 27 is hinged inside the groove 28, and the pull rod 26 passes through the sliding hole 29 and extends to the inside of the groove 28.

[0028] The cover plate 27 and the plug-in board 2 are on the same plane, and the cover plate 27 can be flipped open from the groove 28. Pulling the pull rod 26 can drive the limit block 25 to move out of the limit groove 32, thereby facilitating the replacement of a single damaged composite board 1. The cover plate 27 is placed in the groove 28 to hide the pull rod 26, thereby ensuring the flatness of the surface of the composite board 1.

[0029] The telescopic spring 23 is installed inside the installation cavity 22, and the limiting block 25 is a trapezoidal block structure.

[0030] It should be noted that, by virtue of the trapezoidal structure of the limit block 25, when the composite panel 1 is spliced ​​from top to bottom, the limit block 25 will be squeezed and moved into the interior of the installation cavity 22. When the limit block 25 is aligned with the limit groove 32, the rebound force of the telescopic spring 23 will cause the limit block 25 to be inserted into the interior of the limit groove 32, thereby quickly locking the plug board 2 and the connecting board 3.

[0031] See also Figure 1 , Figure 2 The plug-in board 2 and the plug-in block 21 are an integrated fixed structure, the plug-in board 2 and the plug-in block 21 are combined into a "T"-shaped block structure, the connecting plate 3 is a "U"-shaped structure, and the connecting plate 3 and the side wall of the composite board 1 are on the same plane.

[0032] The adjacent composite panels 1 are connected by snapping the plug-in board 2 and the connecting board 3 together, thereby ensuring the tightness of the composite panels 1.

[0033] The working principle of the above embodiment is as follows: when in use, align the connecting plate 3 on the composite board 1 with the plug-in plate 2 on the adjacent composite board 1, so that the plug-in block 21 is snapped into the inside of the slot 31, which will push the limit block 25 to move into the inside of the installation cavity 22, and make the movable block 24 slide in the installation cavity 22 to squeeze the telescopic spring 23 to make it telescope. When the limit block 25 is aligned with the limit groove 32, the rebound force of the telescopic spring 23 will cause the limit block 25 to be inserted into the inside of the limit groove 32, so that the plug-in plate 2 and the connecting plate 3 are locked together. By operating in sequence, multiple paving slabs can be quickly spliced, and the flatness of the surface of the paving slabs after laying is ensured.
