Description

Technical Field

[0001] This utility model is a road shoulder construction slab, belonging to the field of road shoulder construction. Background Technology

[0002] A road shoulder refers to a strip of road (including hard shoulders and protective shoulders) located from the outer edge of the carriageway to the edge of the roadbed, with a certain width. It is used to maintain the function of the carriageway and for temporary parking, and to serve as lateral support for the road surface. In the existing technology, when pouring the road shoulder, it is necessary to adjust the distance and width between two fixed plates to a suitable level before pouring concrete into the grooves pre-set in the construction slab. However, concrete has a hardening property and is prone to solidifying and leaving residue on the surface of the construction slab, resulting in an uneven surface that affects the appearance of the next batch of road shoulders. When pits appear on the surface of the road shoulder after pouring, secondary repairs are required, which affects the pouring speed of the road shoulder. Therefore, it is necessary to design a road shoulder construction slab that can reduce the amount of concrete residue on the surface of the construction slab. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a road shoulder construction slab to solve the problems mentioned in the background art. This utility model reduces the amount of concrete remaining on the surface of the construction slab, keeps the surface of the construction slab flat, and reduces the impact on the shape of the road shoulder to be poured later.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a road shoulder construction slab, including a fixed plate, with threaded sleeves installed on the top of each of the two fixed plates, the two threaded sleeves respectively installed on a bidirectional screw, an adjusting handle installed at one end of the bidirectional screw, a tapping mechanism installed on one side of the fixed plate, a protective pad installed on one side of the fixed plate, and fixing members installed at both ends of the protective pad, the fixing members being installed on the fixed plate.

[0005] Furthermore, the fixing component includes a positioning frame, which is fixedly mounted on a fixing plate. A connecting plate is installed on the front side of the positioning frame, and an insertion hole is provided on the connecting plate. An insertion opening is provided on the side of the positioning frame away from the connecting plate. A protective pad is inserted inside the insertion opening, and a fixing baffle is installed at both ends of the protective pad. The fixing baffle is located inside the positioning frame.

[0006] Furthermore, rotating plates are installed on both the upper and lower sides of the connecting plate. A through hole is formed on the rotating plate, the size and position of which correspond to the insertion hole. An insertion rod is installed within the through hole, passing through both the through hole and the insertion hole. Fixing plates are installed at both ends of the insertion rod, with the fixing plates located on the side of the rotating plate away from the connecting plate. The two rotating plates are fixedly mounted on a positioning plate. A fixing sleeve is installed on the end of the positioning plate away from the rotating plate. The positioning plate is located on the front side of the positioning frame, and the fixing sleeve is fitted onto the positioning frame.

[0007] Furthermore, the positioning frame has a limiting hole, and two limiting blocks are symmetrically installed inside the fixing sleeve. One end of the limiting block is installed in the telescopic groove, which is opened on the fixing sleeve. A telescopic spring is installed at one end of the limiting block inside the telescopic groove, and the other end of the telescopic spring is installed in the telescopic groove. The position of the limiting block corresponds to the position of the limiting hole.

[0008] Furthermore, the tapping mechanism includes a limiting frame, which is fixedly mounted on a fixed plate. A round rod is installed in the middle of the limiting frame, and the round rod is installed on the output end of an electric push rod. The electric push rod is installed on the side of the limiting frame away from the fixed plate, and a tapping plate is installed at the other end of the round rod.

[0009] Furthermore, a connecting sleeve is installed on the striking plate, the end of the round rod away from the electric push rod is installed in the connecting sleeve, and a buffer pad is installed on the side of the striking plate away from the connecting sleeve.

[0010] The beneficial effects of this utility model are as follows: The road shoulder construction slab of this utility model is constructed by inserting a fixing baffle into the positioning frame and then clamping the protective pad into the insertion port. The rotating plate is driven to rotate along the connecting plate, so that the positioning plate covers the opening on the front side of the positioning frame and drives the fixing sleeve to cover the other side of the positioning frame, thus sealing the insertion port. This fixes the protective pad to the surface of the fixing plate and keeps it taut, preventing the protective pad from moving during use and reducing the area of ​​the fixing plate in direct contact with the concrete surface, thereby reducing the amount of concrete remaining on the surface of the fixing plate.

[0011] When the limiting block on the fixing sleeve is aligned with the limiting hole on the positioning frame, the telescopic spring will rebound, causing the limiting block to lock into the limiting hole. This prevents the protective pad from moving during use and facilitates replacement when there is solidified concrete adhering to the surface of the protective pad. This reduces the maintenance cost of the fixing plate and improves the pouring effect of the road shoulder.

[0012] The electric push rod drives the patting plate to pat the outside of the fixing plate, thereby vibrating the surface of the fixing plate. This, in turn, causes the fixing plate to vibrate the concrete, reducing the gaps between the concrete particles, allowing the concrete to adhere to the surface of the protective pad, improving the pouring effect of the road shoulder, and reducing the probability of potholes appearing on the road shoulder surface.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a road shoulder construction slab, including a fixed plate 1, with threaded sleeves 2 installed on the top of each of the two fixed plates 1. The two threaded sleeves 2 are respectively installed on a bidirectional screw rod 3. An adjusting handle 4 is installed at one end of the bidirectional screw rod 3. A tapping mechanism is installed on one side of the fixed plate 1, and a protective pad 5 is installed on one side of the fixed plate 1. Fixing members are installed at both ends of the protective pad 5. The fixing members are installed on the fixed plate 1. The adjusting handle 4 can drive the bidirectional screw rod 3 to rotate, thereby driving the two threaded sleeves 2 installed on the bidirectional screw rod 3 to move the fixed plates 1 closer or further apart. The distance between the two fixed plates 1 can be adjusted to adapt to road shoulder pouring of different widths.

[0021] Please see Figure 2 and Figure 3The fixing components include a positioning frame 6, which is fixedly mounted on a fixing plate 1. A connecting plate 8 is mounted on the front side of the positioning frame 6, and an insertion hole 9 is provided on the connecting plate 8. An insertion opening 7 is provided on the side of the positioning frame 6 away from the connecting plate 8, and a protective pad 5 is inserted inside the insertion opening 7. Fixed baffles are installed at both ends of the protective pad 5, and the fixed baffles are located inside the positioning frame 6. Rotating plates 16 are mounted on the upper and lower sides of the connecting plate 8. Through holes are provided on the rotating plates 16, and the position and size of the through holes correspond to the insertion holes 9. An insertion rod 17 is installed in the through holes, passing through the through holes and the insertion holes 9. Fixed plates 18 are installed at both ends of the insertion rod 17, and the fixed plates 18 are located on the side of the rotating plates 16 away from the connecting plate 8. The two rotating plates 16 are fixedly mounted on the positioning plate 11. A fixing sleeve 12 is installed at the end of the positioning plate 11 away from the rotating plate 16. The positioning plate 11 is located in front of the positioning frame 6. The fixing sleeve 12 is fitted onto the positioning frame 6. The positioning frame 6 has a limit hole 10. Two limit blocks 15 are symmetrically installed inside the fixing sleeve 12. One end of the limit block 15 is installed in the telescopic groove 13, which is located on the fixing sleeve 12. A telescopic spring 14 is installed at the end of the limit block 15 inside the telescopic groove 13. The other end of the telescopic spring 14 is installed in the telescopic groove 13. The position of the limit block 15 corresponds to the position of the limit hole 10. When the position of the limit block 15 matches the position of the limit hole 10, the telescopic spring 14 rebounds, thereby fixing the protective pad 5 onto the fixing plate 1 and improving the fixing effect of the protective pad 5.

[0022] Please see Figure 4 The patting mechanism includes a limiting frame 19, which is fixedly installed on a fixed plate 1. A round rod 23 is installed in the middle of the limiting frame 19. The round rod 23 is installed on the output end of an electric push rod 24. The electric push rod 24 is installed on the side of the limiting frame 19 away from the fixed plate 1. A patting plate 20 is installed on the other end of the round rod 23. A connecting sleeve 22 is installed on the patting plate 20. The end of the round rod 23 away from the electric push rod 24 is installed in the connecting sleeve 22. A buffer pad 21 is installed on the side of the patting plate 20 away from the connecting sleeve 22. The electric push rod 24 drives the patting plate 20 to move within the limiting frame 19, repeatedly patting the fixed plate 1. This causes the concrete poured between the two fixed plates 1 to vibrate, reducing the gaps between the concrete and improving the pouring effect of the road shoulder.

[0023] Detailed implementation: By inserting the fixed baffle into the positioning frame 6 and then securing the protective pad 5 inside the insertion port 7, the rotating plate 16 is driven to rotate along the connecting plate 8, causing the positioning plate 11 to cover the opening on the front side of the positioning frame 6, and the fixing sleeve 12 to cover the other side of the positioning frame 6, sealing the insertion port 7. This fixes the protective pad 5 tightly to the surface of the fixing plate 1, preventing the protective pad 5 from moving during use, reducing the area of ​​the fixing plate 1 in direct contact with the concrete surface, and thus reducing the amount of concrete remaining on the surface of the fixing plate 1. When the limiting block 15 on the fixing sleeve 12 aligns with the limiting block on the positioning frame 6... When the hole 10 is aligned, the telescopic spring 14 will rebound, causing the limiting block 15 to lock into the limiting hole 10, preventing the protective pad 5 from moving during use and facilitating replacement when there is solidified concrete adhering to the surface of the protective pad 5. This reduces the maintenance cost of the fixing plate 1 and improves the pouring effect of the road shoulder. The electric push rod 24 drives the tapping plate 20 to tap the outside of the fixing plate 1, thereby causing the surface of the fixing plate 1 to vibrate, which in turn causes the concrete to vibrate, reducing the gaps between the concrete and making the concrete adhere to the surface of the protective pad 5, improving the pouring effect of the road shoulder and reducing the probability of potholes appearing on the road shoulder surface.
