Description

Technical Field

[0001] This utility model relates to the field of road construction, and in particular to a construction device for road surface joints. Background Technology

[0002] Road surface engineering connection construction is a crucial step in road construction. It is responsible for connecting road surface works at different construction stages to ensure the smoothness and continuity of the road.

[0003] When constructing a new road surface, workers need to place several reflective traffic cones on the old road surface to warn oncoming vehicles. However, during this process, there is a lack of effective separation devices at the junction of the new and old road surfaces. This can easily cause materials such as cement laid on the new road surface to move onto the old road surface, resulting in an uneven old road surface.

[0004] Therefore, it is necessary to provide a new construction device for road surface joints to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a road surface joint construction device, which solves the problem that during the construction process, the lack of an effective separation device at the joint between the new road surface and the old road surface easily causes the cement and other materials laid at the new road surface to move to the old road surface, resulting in an uneven old road surface.

[0006] The road joint construction device provided by this utility model includes an isolation plate, on which several support legs are fixed at intervals, and on one side of the isolation plate, a pair of first limiting seats and a pair of second limiting seats are fixed at intervals.

[0007] The first limiting seat has a slot on its surface, and the second limiting seat has a pin fixed on one side, with the slot and the pin fitting together.

[0008] In a preferred embodiment, the isolation plate has multiple through slots located between two adjacent support legs, and reinforcing ribs are fixed at the through slots.

[0009] In a preferred embodiment, the top of the locking post is provided with a threaded groove, the top of the first limiting seat is provided with a through hole, and a high-strength screw is provided at the first limiting seat. The threaded end of the high-strength screw passes through the through hole and extends into the threaded groove.

[0010] In a preferred embodiment, an adjusting baffle is provided at the bottom of the through groove, and an L-shaped slide rod is fixedly fixed at intervals on one side of the adjusting baffle. A slide rail is provided on one side of the L-shaped slide rod, and the slide rail is fixed to one side of the isolation plate. One side of the L-shaped slide rod is slidably connected to the slide rail.

[0011] In a preferred embodiment, a limiting hole is provided on the slide rail, and a limiting pin is provided through the L-shaped slide rod, the limiting pin being matched with the size of the limiting hole;

[0012] A pull plate is fixed on the limiting pin.

[0013] In a preferred embodiment, the surface of the support leg is provided with a warning strip and reflective stickers.

[0014] The beneficial effects of this utility model are:

[0015] 1. When using this device, place the isolation plate and support legs on the old road surface. The isolation plate separates the new road surface to be constructed from the old road surface, preventing the cement laid on the new road surface from moving to the old road surface and causing unevenness.

[0016] 2. When it is necessary to combine two isolation plates together, simply insert the locking pin of one isolation plate into the slot, and then screw the threaded end of the high-strength screw through the through hole into the threaded groove to complete the stable connection of the two isolation plates. The operation is simple and convenient. Several isolation plates can be combined and separated, which is convenient for transportation.

[0017] 3. When there is a lot of residual moisture on the old road surface after construction, the workers can move the adjustment baffle upwards. After moving it, insert the limit pin into the limit hole to fix the adjustment baffle. At this time, a gap will be formed between the adjustment baffle and the isolation plate, so that the workers can drain the moisture to the old road surface. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0023] Please refer to Figure 1 , Figure 2 as well as Figure 3 ,in Figure 1 A three-dimensional view of the overall structure of the road surface joint construction device provided by this utility model; Figure 2 for Figure 1 A schematic diagram of the enlarged structure of A shown; Figure 3 for Figure 1 The diagram shows an enlarged structural representation of B.

[0024] In the specific implementation process, such as Figure 1-Figure 3 As shown, the device includes a partition plate 1, on which several support legs 4 are fixed at intervals. Warning strips 18 and reflective stickers 19 are provided on the surface of each support leg 4. A pair of first limiting seats 5 and a pair of second limiting seats 6 are fixed at intervals on one side of the partition plate 1. The surface of the first limiting seat 5 has a slot 7, and a locking post 8 is fixed on one side of the second limiting seat 6. The slot 7 and the locking post 8 are fitted together. Multiple through slots 2 are provided on the partition plate 1, located between adjacent support legs 4. Reinforcing ribs 3 are fixed at the through slots 2. When using this device, the partition plate 1 and support legs 4 are placed on the old road surface. The partition plate 1 separates the new road surface to be constructed from the old road surface, preventing cement laid on the new road surface from moving to the old road surface and causing unevenness.

[0025] The top of the locking post 8 is provided with a threaded groove 9, and the top of the first limiting seat 5 is provided with a through hole 10. A high-strength screw 11 is provided at the first limiting seat 5. The threaded end of the high-strength screw 11 passes through the through hole 10 and extends into the threaded groove 9. When it is necessary to combine two isolation plates 1 together, it is only necessary to insert the locking post 8 of one of the isolation plates 1 into the locking groove 7, and then screw the threaded end of the high-strength screw 11 through the through hole 10 into the threaded groove 9 to complete the stable connection of the two isolation plates 1. The operation is simple and convenient. Several isolation plates 1 can be combined and separated, which is convenient for transportation.

[0026] An adjusting baffle 12 is provided at the bottom of the channel 2. An L-shaped slide rod 13 is fixed at intervals on one side of the adjusting baffle 12. A slide rail 14 is provided on one side of the L-shaped slide rod 13. The slide rail 14 is fixed to one side of the isolation plate 1. One side of the L-shaped slide rod 13 is slidably connected to the slide rail 14. A limit hole 15 is opened on the slide rail 14. A limit pin 16 is provided through the L-shaped slide rod 13. The limit pin 16 matches the size of the limit hole 15. A pull plate 17 is fixed on the limit pin 16 to facilitate the user to move the limit pin 16. When there is a lot of residual water on the old road surface, the workers can move the adjusting baffle 12 upward. After the movement is completed, the limit pin 16 is inserted into the limit hole 15 to complete the fixing of the adjusting baffle 12. At this time, a gap will be formed between the adjusting baffle 12 and the isolation plate 1, so that the workers can drain the water to the old road surface.

[0027] The working principle of this utility model is as follows: When this device is used, the isolation plate 1 and the support leg 4 are placed on the old road surface. The isolation plate 1 separates the new road surface to be constructed from the old road surface, so as to prevent the cement laid on the new road surface from moving to the old road surface and causing the old road surface to become uneven.

[0028] When it is necessary to combine two isolation plates 1 together, simply insert the locking post 8 of one of the isolation plates 1 into the slot 7, and then screw the threaded end of the high-strength screw 11 through the through hole 10 into the threaded groove 9 to complete the stable connection of the two isolation plates 1. The operation is simple and convenient. Several isolation plates 1 can be combined and separated, which is convenient for transportation.

[0029] When there is a lot of residual moisture on the old road surface after construction, the workers can move the adjustment baffle 12 upwards. After the movement is completed, the limit pin 16 is inserted into the limit hole 15 to fix the adjustment baffle 12. At this time, a gap will be formed between the adjustment baffle 12 and the isolation plate 1, so that the workers can drain the moisture to the old road surface.
