Technical Field

[0001] The utility model relates to the technical field of subgrade joint settlement prevention, in particular to a subgrade joint settlement prevention component. Background Technique

[0002] In civil engineering construction, planning and construction need to be carried out for roads, which is the content of road engineering. The subgrade is the foundation of the track or road surface, and is a geotechnical structure formed by excavation or filling. The main function of the subgrade is to provide necessary conditions for the laying of the track or road surface and the operation of trains or vehicles, and to bear the static and dynamic loads of the track and rolling stock or the road surface and traffic loads, and at the same time transfer and disperse the loads deep into the foundation;

[0003] During road construction, construction joints will inevitably occur, that is, the junction. The junction is the weakest part, and uneven settlement is likely to occur when receiving different loads, which will cause cracks on the subgrade surface. Over time, the road will be damaged. Currently, when dealing with settlement problems, grids are directly laid at the junction, but the laying of grids requires a large amount of human resources, and the grids are directly placed on the subgrade surface without being effectively fixed in alignment. When constructing on the upper part of the grids, it is easy to shift, resulting in a reduction in the dust prevention effect.

[0004] In view of the above problems, the inventor proposes a subgrade joint settlement prevention component to solve the above problems. Content of the Utility Model

[0005] In order to solve the problem that when directly laying grids under the lower part of the road junction for prevention, a large amount of human resources are consumed during laying, and the grids are not effectively fixed and are prone to shift; the purpose of the utility model is to provide a subgrade joint settlement prevention component.

[0006] To solve the above technical problems, the utility model adopts the following technical scheme: A subgrade joint settlement prevention component includes a first fixing plate and a second fixing plate. A roller shaft is rotatably installed in the middle of one side of the first fixing plate. Symmetrically distributed threaded grooves are opened in the middle of both ends of the first fixing plate. A second bolt is threadedly installed in the middle of the two threaded grooves. The second bolt slidably penetrates through the roller shaft. One end of the second bolt is fixedly installed with a first handle. Symmetrically distributed fixing blocks are provided on both sides of the first fixing plate and the second fixing plate. A second screw rod is rotatably installed in the middle of two of the fixing blocks. The outer surface of the second screw rod is provided with left and right hand threads. One side of the first fixing plate and the second fixing plate are threadedly installed on the outer surface of the second screw rod.

[0007] Preferably, two symmetrically distributed first bolts are rotatably installed on the outer surface of the roller shaft, a first clamping plate is threadedly installed in the middle of the two first bolts, a first screw rod is rotatably installed in the middle of the second fixing plate, a positive and negative thread is provided on the outer surface of the first screw rod, and two symmetrically distributed second clamping plates are threadedly installed on the outer surface of the first screw rod.

[0009] 1. This application can lay out the anti-settlement grille and place it at the settlement junction, avoiding the need for manual laying, which consumes a lot of manpower, and can fix the grille, preventing the grille from shifting when covering the upper part of the grille with soil layer or concrete, making the anti-settlement of the junction more stable.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment: As Figures 1-5 shown, the present utility model provides a subgrade junction anti-settlement component, including a first fixing plate 1 and a second fixing plate 2. A roller shaft 11 is rotatably installed in the middle of one side of the first fixing plate 1. Symmetrically distributed threaded grooves 141 are respectively opened in the middle of both ends of the first fixing plate 1. A second bolt 14 is threadedly installed in the middle of the two threaded grooves 141. The second bolt 14 slidably penetrates through the roller shaft 11. One end of the second bolt 14 is fixedly installed with a first handle 142. Symmetrically distributed fixing blocks 32 are provided on both sides of the first fixing plate 1 and the second fixing plate 2. A second screw rod 3 is rotatably installed in the middle of two of the fixing blocks 32. The outer surface of the second screw rod 3 is provided with left and right hand threads. One side of the first fixing plate 1 and the second fixing plate 2 are threadedly installed on the outer surface of the second screw rod 3.

[0020] Two symmetrically distributed first bolts 12 are rotatably installed on the outer surface of the roller shaft 11. A first clamping plate 13 is threadedly installed in the middle of the two first bolts 12. A first screw rod 21 is rotatably installed in the middle of the second fixing plate 2. The outer surface of the first screw rod 21 is provided with left and right hand threads. Two symmetrically distributed second clamping plates 23 are threadedly installed on the outer surface of the first screw rod 21.

[0021] A grille 5 is provided on the relative side of the two second clamping plates 23. The other end of the grille 5 is in contact with the first clamping plate 13. By setting the grille 5, by spreading the grille 5 open at the junction where settlement prevention is required, settlement cracking is avoided.

[0022] Two symmetrically distributed ground nails 33 are slidably installed at the lower part of the four fixing blocks 32. By setting the ground nails 33, by inserting the ground nails 33 into the ground to fix the fixing blocks 32, the device is limited and fixed to be fixed on the ground. When laying soil layer or concrete on the upper part of the grille 5, the grille 5 will not shift.

[0023] One end of the second screw rod 3 penetrates through the fixing block 32, and a second handle 31 is fixedly installed at the end of the second screw rod 3 penetrating through the fixing block 32. By providing the second handle 31, rotating the second handle 31 drives the second screw rod 3 to rotate, thereby driving the first fixing plate 1 and the second fixing plate 2 to move away from each other, and then laying out the grille 5.

[0024] An installation hole 111 is formed in the middle of the roller shaft 11, and the middle part of the second bolt 14 is slidably clamped inside the installation hole 111. By providing the installation hole 111, the roller shaft 11 can be limited by slidably clamping the middle part of the second bolt 14 inside the installation hole 111. When the first fixing plate 1 and the second fixing plate 2 move towards the opposite ends, the roller shaft 11 wound with the grille 5 can rotate, and then the grille 5 is opened.

[0025] A groove 22 is formed in the middle of one side of the second fixing plate 2, and two second clamping plates 23 are slidably clamped inside the groove 22. By providing the groove 22, the two second clamping plates 23 are limited by the groove 22, so that when the first screw rod 21 rotates, the two second clamping plates 23 move relatively, and then the grille 5 is clamped and fixed.

[0026] A limiting rod 4 is provided on the sides of the first fixing plate 1 and the second fixing plate 2 away from the second screw rod 3, and one side of the first fixing plate 1 and the second fixing plate 2 is slidably installed on the outer surface of the limiting rod 4. By providing the limiting rod 4, after the limiting rod 4 limits the first fixing plate 1 and the second fixing plate 2, by rotating the second handle 31, the second screw rod 3 is driven to rotate, thereby driving the first fixing plate 1 and the second fixing plate 2 to move away from each other, and then laying out the grille 5.

[0027] Working principle: During actual use, the fixing block 32 is fixedly installed on the ground by the ground nail 33, that is, the second screw rod 3 is limited. The roller shaft 11 wound with the grille 5 is placed in the middle of the first fixing plate 1. By threadedly installing the second bolt 14 in the threaded groove 141, the middle part of the second bolt 14 is slidably clamped inside the installation hole 111, that is, the roller shaft 11 is limited. By rotating the second handle 31, under the rotation of the second handle 31, the first fixing plate 1 and the second fixing plate 2 threadedly installed on the outer surface of the second screw rod 3 move away from each other, so that the grille 5 is opened and laid at the junction where settlement needs to be placed;

[0028] By installing one end of the grille 5 on one side of the first clamping plate 13 and rotating the two first bolts 12, the first clamping plate 13 is moved closer to the roller shaft 11, that is, the one end of the grille 5 is limited and fixed. By placing the other end of the grille 5 between the two second clamping plates 23 and rotating the first screw rod 21, the two second clamping plates 23 move relatively to limit and clamp the grille 5 placed in the middle. When the first fixing plate 1 and the second fixing plate 2 move away from each other, the grille 5 is opened by the mutual cooperation of the second clamping plate 23 and the first clamping plate 13, and when laying soil layer or concrete on the upper part of the grille 5, it will not shift.

[0029] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these changes and modifications.
