[0024] It should be noted that due to the difficulties and insufficient accuracy of positioning of traditional roadbed paving templates, as well as the poor stability and easy tilting of the templates, the construction efficiency and safety are restricted. The high flexibility of the positioning device of this solution and the adjustable depth of the plug-in cone 12 can accurately adapt to different roadbed requirements and ensure the stable placement of the substrate 1. The adjustability of the length of the connecting rod 2 not only facilitates storage and transportation, but also improves the adaptability and stability of the substrate 1, ensuring the flatness and stability of the roadbed paving. The design of the reinforcing ribs 15 significantly enhances the strength and stability of the substrate 1, extends its service life, reduces maintenance costs, and improves construction efficiency and quality. The anti-slip texture 16 on the bottom side of the substrate 1 effectively prevents sliding, ensures the safety of construction personnel, and provides a solid foundation for efficient and safe construction. In summary, this device brings higher efficiency and quality to roadbed paving through its flexibility, stability and safety.

[0025] Specifically, in this embodiment, the scheme mainly includes a group of parallelly arranged base plates 1; a positioning device arranged on the outside of the base plates 1; and a connecting device arranged above the two base plates 1; the base plates 1 are the main supporting and fixing structures for fixing the base plates 1 during roadbed paving; in order to ensure the accurate position of the base plates 1 during the paving process, a positioning device is arranged on the outside of the base plates 1; the connecting device is composed of a number of connecting rods 2 arranged on the two base plates 1; each connecting rod 2 includes an inner rod 3 and an outer rod 4; the outer rod 4 is sleeved on the outside of the inner rod 3 and can slide with it; this design allows the length of the connecting rod 2 to be adjusted to a certain extent to adapt to the requirements of roadbeds of different sizes or shapes; by adjusting the length of the connecting rod 2, the stability and adaptability of the base plates 1 at different positions can be ensured;

[0026] A connecting block 5 is provided on the side where the outer rod 4 and the inner rod 3 are away from each other; a clamping block 6 is provided on the bottom side of the connecting block 5; a plurality of clamping grooves 7 are provided on the upper surfaces of the two base plates 1, and the shape and size of the clamping grooves 7 match the clamping blocks 6 on the bottom side of the connecting block 5; when the connecting rod 2 is adjusted to an appropriate length, the clamping block 6 on the bottom side of the connecting block 5 is clamped with the clamping groove 7 on the base plate 1 to fix the connecting rod 2 to the base plate 1; this clamping matching method is both firm and easy to operate, and can ensure the stability and reliability between the connecting rod 2 and the base plate 1.

[0027] In a further preferred embodiment of the present invention, Figures 1-3 As shown, the connecting device further comprises: a plurality of first threaded holes 8 provided on the inner rod 3 and the outer rod 4; two corresponding first threaded holes 8 are threadedly fitted with the same first fastening bolt 9.

[0028] In this embodiment, when it is necessary to adjust the length of the connecting rod 2, first, the operator loosens the first fastening bolt 9, which can eliminate the fixed constraint between the inner rod 3 and the outer rod 4, enabling them to slide freely; then, the operator can adjust the overall length of the connecting rod 2 by sliding the inner rod 3 or the outer rod 4 according to actual needs until the appropriate position is reached;

[0029] After confirming that the length of the connecting rod 2 has been adjusted to the appropriate position, the operator tightens the first fastening bolt 9 again; this process is achieved by screwing the first fastening bolt 9 into the corresponding two first threaded holes 8. When the bolt is tightened, it firmly fixes the inner rod 3 and the outer rod 4 together, ensuring that the length of the connecting rod 2 will not change unnecessarily during subsequent use and improving the portability of the storage of the connecting rod 2 at the same time.

[0030] In a further preferred embodiment of the present utility model, as Figures 1-3 shown, the positioning device includes: two positioning blocks 10 arranged outside the substrate 1; a positioning plate 11 is slidably fitted on each of the two positioning blocks 10; a plugging cone 12 is provided at the bottom side of the two positioning plates 11.

[0031] In this embodiment, the sliding fit design between the positioning block 10 and the positioning plate 11 does allow the operator to flexibly adjust the height of the positioning plate 11. This design ensures that the plugging cone 12 can be accurately and deeply inserted into the roadbed, providing stable support and fixation for the substrate 1. The entire positioning process is not only fast but also accurate, greatly improving the construction efficiency and ensuring the construction quality at the same time. By precisely adjusting the height of the positioning plate 11 and the insertion depth of the plugging cone 12, the construction personnel can ensure the flatness and stability of the roadbed laying, further enhancing the quality and durability of the entire project.

[0032] In a further preferred embodiment of the present utility model, as Figures 1-3 shown, the positioning device further includes: a plurality of second threaded holes 13 provided on the positioning block 10 and the positioning plate 11; the same second fastening bolt 14 is threadedly fitted on two corresponding second threaded holes 13.

[0033] In this embodiment, when it is necessary to adjust the position of the positioning plate 11 relative to the positioning block 10, the second fastening bolt 14 can be loosened first to enable the positioning plate 11 and the positioning block 10 to move freely. After adjusting to the appropriate position, the second fastening bolt 14 is tightened to fix the positioning plate 11 and the positioning block 10 together. This design allows for flexible adjustment of the positioning device to meet the requirements of roadbeds with different depths.

[0034] In a further preferred embodiment of the present utility model, as Figures 1-2As shown, a reinforcing rib 15 is provided on the outer side wall of the substrate 1, and the reinforcing rib 15 is arranged in any one of a cross shape, a cross arrangement or a grid arrangement.

[0035] In this embodiment, the design of setting the reinforcing rib 15 can not only improve the strength and stability of the substrate 1, but also increase its service life and durability. At the same time, the design of these reinforcing ribs 15 can also improve the construction efficiency and quality and reduce the maintenance cost.

[0036] In a further preferred embodiment of the present utility model, as Figure 3 shown, an anti-slip pattern 16 is provided on the bottom side of the substrate 1.

[0037] In this embodiment, the design of the anti-slip pattern 16 is to increase the contact surface between the bottom surface of the substrate 1 and the contact surface. When the substrate 1 is placed on the contact surface, the anti-slip pattern 16 can form more contact points and friction surfaces, thereby enhancing the friction force between the substrate 1 and the contact surface. This frictional force can prevent the substrate 1 from sliding or moving when subjected to an external force, ensuring that the substrate 1 can be stably fixed in its position.

[0038] Working principle: During the construction process of paving and fixing the substrate 1 on the roadbed, the stability and fixity of the substrate 1 play a crucial role; to ensure the accurate position and stable fixation of the substrate 1, the design of the substrate 1 includes key elements such as the anti-slip pattern 16, the positioning device and the connecting device, etc.;

[0039] First of all, an anti-slip pattern 16 is provided on the bottom side of the substrate 1, and the design of these patterns is aimed at increasing the coefficient of friction between the bottom surface of the substrate 1 and the contact surface; when the substrate 1 is placed on the road surface or other contact surfaces, the anti-slip pattern 16 can effectively form more contact points and friction surfaces, thereby greatly enhancing the frictional force between the substrate 1 and the contact surface; this enhanced frictional force can prevent the substrate 1 from sliding or moving when subjected to an external force, ensuring that the substrate 1 can be stably fixed in its position;

[0040] Secondly, in order to ensure the accurate position of the substrate 1 during the paving process, a positioning device is provided on the outer side of the substrate 1; this positioning device includes a positioning block 10 and a positioning plate 11, and their sliding fit design allows the operator to flexibly adjust the height of the positioning plate 11; by precisely adjusting the height of the positioning plate 11 and the insertion depth of the insertion cone 12, the construction personnel can ensure the flatness and stability of the roadbed paving; this design ensures that the insertion cone 12 can accurately and deeply insert into the roadbed, providing a firm support and fixation for the substrate 1; the entire positioning process is both fast and accurate, which helps to improve the construction efficiency and quality;

[0041] In order to adapt to the requirements of roadbeds of different sizes, the design of the connecting device allows the length of the connecting rod 2 to be adjusted to a certain extent; the connecting device is composed of a plurality of connecting rods 2 arranged on two base plates 1, each connecting rod 2 includes an inner rod 3 and an outer rod 4; the outer rod 4 is sleeved on the outer side of the inner rod 3 and can slide with it; when it is necessary to adjust the length of the connecting rod 2, the operator will first loosen the first fastening bolt 9 so that the inner rod 3 and the outer rod 4 can slide freely; then, by sliding the inner rod 3 or the outer rod 4, the connecting rod 2 is adjusted to a suitable length; after confirming the position, the first fastening bolt 9 is tightened to fix it, ensuring that the connecting rod 2 will not undergo unnecessary length changes during subsequent use;

[0042] A connecting block 5 is provided on the side where the outer rod 4 and the inner rod 3 are away from each other; a clamping block 6 is provided on the bottom side of the connecting block 5, and these clamping blocks 6 can be clamped with the clamping groove 7 provided on the base plate 1; the shape and size of the clamping groove 7 match the clamping block 6 on the bottom side of the connecting block 5, and when the connecting rod 2 is adjusted to an appropriate length, the fixing of the connecting rod 2 and the base plate 1 is achieved by clamping; this clamping matching mode is both firm and easy to operate, ensuring the stability and reliability between the connecting rod 2 and the base plate 1;

[0043] In addition, the design of the base plate 1 also includes reinforcing ribs 15; they can not only improve the strength and stability of the base plate 1, but also increase its service life and durability; by enhancing the bearing capacity and stability of the base plate 1, the design of these reinforcing ribs 15 helps to improve construction efficiency and quality and reduce maintenance costs.
