Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0015] Please see Figures 1 to 2This utility model provides a technical solution: a concrete backrest support structure for road curbstones, including a fixed baffle 2 set on the outside of the curbstone 1 and a movable baffle 3 set on the inside of the curbstone 1. The movable baffle 3 and the fixed baffle 2 are arranged in parallel and spaced apart, and the movable baffle 3 is spaced apart from the inner side of the curbstone 1 to form a concrete pouring gap. The distance between the movable baffle 3 and the curbstone 1 is adjustable, and the distance between the movable baffle 3 and the fixed baffle 2 is adjustable, which can adapt to the pouring of backrest concrete for curbstones 1 of different thicknesses, and solves the problems of troublesome loading and unloading and inconvenient turnover of concrete backrest support for curbstones.

[0016] In this embodiment, as a preferred option, a through second threaded hole 302 is provided on the movable baffle 3. A suitable clamping threaded rod 5 is connected to the internal thread of the second threaded hole 302. The end of the clamping threaded rod 5 is vertically pressed against the inner wall of the curbstone 1. The movable baffle 3 is positioned at an appropriate location according to the pouring thickness of the backrest concrete. After the position of the movable baffle 3 is determined, as the clamping threaded rod 5 is pressed against the curbstone 1, the movable baffle 3 can be subjected to a thrust away from the curbstone 1. A rubber pad 7 is fixed to the end of the clamping threaded rod 5 facing the curbstone 1 to prevent the clamping threaded rod 5 from causing wear and damage to the curbstone 1.

[0017] Furthermore, a through first threaded hole 301 is provided on the movable baffle 3. An appropriate adjusting threaded rod 4 is connected to the first threaded hole 301. The end of the adjusting threaded rod 4 is vertically fixed to the center of the fixed baffle 2. As the adjusting threaded rod 4 is adjusted, the fixed baffle 2 can be tightly hooked to the outside of the curbstone 1, thereby causing the movable baffle 3 to be subjected to a pulling force close to the curbstone 1. Combined with the pushing force of the clamping threaded rod 5 on the movable baffle 3, the forces in the two directions can stabilize the movable baffle 3 in a fixed position, thereby ensuring the stability of the pouring gap and ensuring the stable progress of the pouring operation.

[0018] In this embodiment, as a preferred option, an inclined support rod 6 is provided between the movable baffle 3 and the adjusting threaded rod 4. The inclined support rod 6 is located on the side of the movable baffle 3 away from the curbstone 1. The inclined support rod 6 and the adjusting threaded rod 4 form a triangular support structure for the movable baffle 3, further ensuring the stability of the entire formwork structure. Specifically, one end of the inclined support rod 6 is fixedly connected to the bottom of the movable baffle 3, and the other end of the inclined support rod 6 is provided with a connecting ring 601 through which the adjusting threaded rod 4 passes. The adjusting threaded rod 4 is threaded with a stop nut 8 on the side of the connecting ring 601 away from the curbstone 1. When the position of the movable baffle 3 is fixed, the stop nut 8 is locked towards the curbstone 1, which can ensure that the entire formwork structure is more stable under force.

[0019] In this invention, the working steps of the device are as follows: 1. Select an appropriate location to place the movable baffle 3 according to the thickness of the backrest concrete pouring; 2. Rotate the adjusting threaded rod 4 to ensure that the fixed baffle 2 is firmly attached to the outer wall of the curbstone 1 while the movable baffle 3 remains in the same position. 3. Rotate the clamping threaded rod 5 so that the rubber pad 7 at the end of the clamping threaded rod 5 is firmly pressed against the back wall of the curb stone 1; 4. Tighten the stop nut 8 on the outside of the connecting ring 601 of the inclined support rod 6 towards the curb stone 1; 5. Concrete is poured in the gap between the movable baffle 3 and the curbstone 1. The pouring height of the back concrete is lower than the height of the clamping threaded rod 5, so as to facilitate the subsequent removal of the clamping threaded rod 5.
