Description

Technical Field

[0001] This utility model relates to the field of airport road technology, and in particular to a road crack prevention structure based on airport road design. Background Technology

[0002] An airport, also known as an airfield or airport, is more formally called an aviation station. Airports come in different sizes and, in addition to runways, typically include facilities such as control towers, aprons, passenger terminals, and maintenance depots. They also provide airport control services, air traffic control, and other services. The structure of an airport runway directly affects an aircraft's takeoff capability. If cracks appear on the runway surface, it will seriously affect the safety of aircraft takeoff and landing. Most existing technologies involve grooving the airport road surface to prevent cracks from forming due to thermal expansion and contraction. However, under the long-term effects of aircraft takeoffs and landings, cracks inevitably form in the grooved areas. Therefore, we propose a road crack-resistant structure based on airport road design.

[0003] Chinese patent document CN217078272U discloses a crack-resistant road structure based on airport road design, including a joint filler plate. The joint filler plate has two symmetrically arranged adjustment grooves on its upper part. Multiple installation grooves are evenly arranged on the inner wall of each adjustment groove. A positioning rod is fixedly connected inside each installation groove. A spring is movably fitted onto the positioning rod. A slider is fixedly connected to the outer end of the spring. Multiple spring blocks are slidably connected inside the adjustment grooves. Multiple telescopic grooves are evenly arranged on the bottom surface of the joint filler plate. An adjustment plate is slidably connected inside each telescopic groove. A support base is fixedly installed at the lower end of each adjustment plate. Multiple snap-fit ​​grooves are evenly arranged on the outer wall of the adjustment plate. Two symmetrically arranged movable grooves are formed at the lower part of each telescopic groove. A telescopic spring is fixedly connected to the inner wall of each movable groove. A snap-fit ​​block is fixedly installed at the inner end of each telescopic spring. The aforementioned crack-resistant road structure based on airport road design has shortcomings. Although the device can prevent cracking of airport roads, it has limitations. The connection between the joint filler plates can only be achieved by spring pushing the spring-loaded block for splicing, and cannot be snapped together. It has poor stability in use, and its complex structure makes it prone to deformation during use, resulting in a short service life.

[0004] Therefore, in order to solve this problem, we propose a road crack prevention structure based on airport road design. Utility Model Content

[0005] The purpose of this utility model is to provide a road crack prevention structure based on airport road design, aiming to solve the problem in the above-mentioned background technology that the existing crack prevention road structure based on airport road design has poor stability because the joint filler can only be spliced ​​together and cannot be snapped together.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a road crack prevention structure based on airport road design, comprising a joint filler plate body, wherein a first mounting groove is formed on the side wall of the joint filler plate body, and a spring-loaded block assembly is disposed inside the joint filler plate body, the spring-loaded block assembly being located within the first mounting groove, the spring-loaded block assembly including a first spring-loaded block, a fourth mounting groove being formed on the side wall of the first spring-loaded block, a fifth mounting groove being formed on the side wall of the first spring-loaded block, and a first limiting post being disposed inside the first spring-loaded block, the first limiting post being located within the fifth mounting groove, and a second limiting post being disposed inside the first spring-loaded block.

[0012] This utility model has the following beneficial effects:

[0013] In this invention, multiple sets of spring-loaded block assemblies are provided. The joint filler plate body can cooperate with the support. When an aircraft passes over, the joint filler plate body can share the force received by the gap, making the gap more stable. Then, through multiple first and second spring-loaded blocks, the gap can be supported more comprehensively, making the support effect of the spring-loaded plate on the gap better, making the gap more stable, avoiding cracks caused by the groove. At the same time, because the use of springs does not affect the thermal expansion and contraction of the road surface, and the first and second spring-loaded blocks have simple shapes, are not easy to deform, and increase service life. Furthermore, the first and second spring-loaded blocks can be interlocked, increasing the stability of the connection between multiple joint filler plate bodies, making it more in line with the design requirements of airport roads.

[0022] Reference Figure 1-4This utility model provides an embodiment of a road crack prevention structure based on airport road design, comprising a joint filler plate body 1, a first mounting groove 101 formed on the side wall of the joint filler plate body 1, a spring-loaded block assembly 2 disposed inside the joint filler plate body 1, the spring-loaded block assembly 2 disposed within the first mounting groove 101, the spring-loaded block assembly 2 comprising a first spring-loaded block 21, a fourth mounting groove 210 formed on the side wall of the first spring-loaded block 21, a fifth mounting groove 211 formed on the side wall of the first spring-loaded block 21, a first limiting post 22 disposed inside the first spring-loaded block 21, the first limiting post 22 disposed within the fifth mounting groove 211, and a first telescopic rod 23 disposed inside the first spring-loaded block 21. Located within the fourth mounting slot 210, the first telescopic rod 23 has a first spring 24 on its side wall. The sealant body 1 has a second spring-loaded block assembly 3 inside, which is located within the first mounting slot 101. The second spring-loaded block assembly 3 includes a second spring-loaded block 31. The side wall of the second spring-loaded block 31 has a sixth mounting slot 310 and a seventh mounting slot 311. The second spring-loaded block 31 has a second limiting post 32 inside, which is located within the seventh mounting slot 311. The second spring-loaded block 31 has a second telescopic rod 33 inside, which is located within the sixth mounting slot 310. The side wall of the second telescopic rod 33 has a second spring 34.

[0023] When the two sealant board bodies 1 are spliced ​​together, they can be engaged by the first spring-loaded block 21 and the second spring-loaded block 31 in multiple sets of spring-loaded block assembly 1 2 and spring-loaded block assembly 2 3, which reduces the gap generated by splicing the two sealant board bodies 1 and makes the splicing of the two sealant board bodies 1 more secure.

[0024] The lower end of the caulking board body 1 is provided with a second mounting groove 102, and the side wall of the caulking board body 1 is provided with a third mounting groove 103. A support 12 is provided inside the caulking board body 1, and the support 12 is located in the second mounting groove 102. A slot 121 is provided on the side wall of the support 12. A pull rod 13 is provided inside the caulking board body 1, and the pull rod 13 is located in the third mounting groove 103. A limit ring 131 is provided on the side wall of the pull rod 13, and a third spring 132 is provided on the side wall of the pull rod 13. The third spring 132 is located at the end of the limit ring 131 away from the support 12. It is used to pull the pull rod 13 to drive the limit ring 131 to squeeze the third spring 132, and then make the pull rod 13 slide out of the slot 121. Then, after pulling the support 12 to a suitable position, the pull rod 13 is released. The elastic force of the third spring 132 drives one end of the pull rod 13 to be locked into the slot 121 through the limit ring 131, thereby realizing the adjustment of the height of the caulking board body 1.

[0025] The end of the first limiting post 22 away from the first spring-loaded block 21 is fixedly connected to the sealant plate body 1. The end of the first telescopic rod 23 away from the first spring-loaded block 21 is fixedly connected to the sealant plate body 1. The end of the second limiting post 32 away from the second spring-loaded block 31 is fixedly connected to the sealant plate body 1. The end of the second telescopic rod 33 away from the second spring-loaded block 31 is fixedly connected to the sealant plate body 1. These are used to limit the first spring-loaded block 21 and the second spring-loaded block 31. Furthermore, the first spring 24 and the second spring 34 are used to increase the support of the first spring-loaded block 21 and the second spring-loaded block 31 for the gap, which can make the gap more stable.

[0026] A first connecting block 11 is provided on the side wall of the joint filler body 1, and a second connecting block 111 is provided on the side wall of the joint filler body 1 away from the first connecting block 11. The first connecting block 11 in one joint filler body 1 is engaged with the second connecting block 111 in another joint filler body 1, thereby further reducing the gap generated by splicing the two joint filler body 1.

[0027] The third mounting groove 103 is cross-shaped and is used to limit the limiting ring 131 and the third spring 132, preventing the limiting ring 131 and the third spring 132 from sliding directly out of the third mounting groove 103.

[0028] The end of the support 12 away from the caulking board body 1 is trapezoidal in shape, which is used to increase the support area of ​​the support 12 and increase stability.

[0029] Working principle: First, when two sealant board bodies 1 are spliced ​​together, the first spring-loaded block 21 and the second spring-loaded block 31 in multiple sets of spring-loaded block assemblies 1-2 and 2-3 can be engaged. At the same time, the first connecting block 11 in one sealant board body 1 is engaged with the second connecting block 111 in the other sealant board body 1, further reducing the gap generated by splicing the two sealant board bodies 1 and making the splicing of the two sealant board bodies 1 more secure. When the height of the sealant board body 1 needs to be adjusted, the pull rod 13 is pulled to drive the limiting ring 131 to compress the third spring 132, and then the pull rod 13 slides out of the slot 121. After pulling the support 12 to the appropriate position, the pull rod 13 is released. The elastic force of the third spring 132 drives one end of the pull rod 13 to be engaged in the slot 121 through the limiting ring 131, realizing the adjustment of the height of the sealant board body 1, so that it can adapt to gaps of different depths and avoid the problem of the sealant board body 1 being difficult to install due to uneven gap cutting depth.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
