Technical Field

[0001] The utility model relates to the technical field of building formwork, in particular to a precast formwork for concrete guardrails. Background Art

[0002] Concrete guardrails are important components in bridge and highway construction, which are set to ensure driving safety. Generally, they are divided into precast concrete guardrails and cast-in-situ concrete guardrails. Precast concrete guardrails are prefabricated through backcourt flow and assembled at the construction site, thus realizing the rapid construction of concrete guardrails.

[0003] Existing concrete guardrails are generally cast with spliced formwork, which generally includes a bottom formwork, two side formworks and two end formworks. For scenarios such as highways or bridges where a higher degree of protection safety is required, thicker concrete guardrails are needed. For scenarios such as urban roads where a lower degree of protection safety is required, thinner concrete guardrails can reduce the cost of raw materials and transportation. However, the size and shape of precast formwork are fixed and cannot fully meet the usage requirements of different scenarios. Summary of the Utility Model

[0004] In order to make up for the deficiencies of existing technical problems, the purpose of the utility model is to provide an installation component to make the distance between the two movable side plates be the thickness of the concrete guardrail, which solves the problem that the size and shape of the precast formwork are fixed and cannot fully meet the usage requirements of different scenarios.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0017] Please refer to Figures 1-4, a precast formwork for concrete guardrails, comprising a bottom plate 1 and movable side plates 2. The top of the bottom plate 1 is fixedly connected with end plates 3. Installation grooves 4 are formed in the outer walls of the bottom plate 1 and the end plates 3. Fixed blocks 5 are fixedly connected to the inner walls of the installation grooves 4. Clamping blocks 6 are fixedly connected to the outer walls of the movable side plates 2. Specifically, there are two movable side plates 2 on the left and right, and two end plates 3 on the front and back. The installation grooves 4 are evenly and symmetrically arranged on the bottom plate 1 and the end plates 3. The clamping blocks 6 are evenly distributed on the two movable side plates. An installation component is used to install the movable side plates 2 at different positions on the bottom plate 1 and the end plates 3. The installation component is respectively connected to the fixed blocks 5 and the clamping blocks 6.

[0018] Please refer to Figures 1-4 , the installation component includes an L-shaped plate 7 rotatably connected to the inner wall of the fixed block 5. A stabilizing rod 8 is rotatably connected to the inner wall of the fixed block 5. A sliding groove 9 is formed in the outer wall of the L-shaped plate 7. The outer wall of the stabilizing rod 8 is slidably connected to the inner wall of the sliding groove 9. The top of the stabilizing rod 8 is fixedly connected with a threaded bolt 10. A stabilizing nut 11 is threadedly connected to the outer wall of the threaded bolt 10. Specifically, the L-shaped plate 7 and the stabilizing plate rotate around the connection point with the fixed block 5 as the center. When the stabilizing plate contacts the inner wall of one side of the sliding groove 9, it can drive the L-shaped plate 7 to rotate so that the installation block 15 is disengaged from the clamping groove 16, and the movable side plate 2 can be disassembled from the bottom plate 1 and the end plates 3. The stabilizing nut 11 is always located above the L-shaped plate 7 and cannot pass through the sliding groove 9. By setting the L-shaped plate 7, rotating the stabilizing nut 11 moves downward along the surface of the threaded bolt 10 until the stabilizing nut 11 contacts the top of the L-shaped plate 7. The L-shaped plate 7 drives the installation block 15 to move downward until the installation block 15 moves into the clamping groove 16, so that the movable side plate 2 can be stably placed at the required position, and the installation and disassembly are convenient, improving the production efficiency of the concrete guardrail.

[0019] Please refer to Figures 1-4, One end of the L-shaped plate 7 is fixedly connected with an adjusting cylinder 12. The inner wall of the adjusting cylinder 12 is slidably connected with an adjusting screw 13. One end of the adjusting cylinder 12 is rotatably connected with an adjusting nut 14. The inner wall of the adjusting nut 14 is threadedly connected with the outer wall of the adjusting screw 13. One end of the adjusting screw 13 is fixedly connected with a mounting block 15. A clamping groove 16 is formed at the top of the clamping block 6. The outer wall of the mounting block 15 is slidably connected with the inner wall of the clamping groove 16. Specifically, the adjusting screw 13 can be retracted into the adjusting cylinder 12. When the adjusting nut 14 rotates, it can drive the adjusting screw 13 to expand and contract, that is, the mounting block 15 expands and contracts, so as to be applicable to the movable side plates 2 at different positions. By setting the mounting assembly, the distance between the two movable side plates 2 is the thickness of the concrete guardrail. Rotate the adjusting nut 14 until the mounting block 15 moves to the clamping block 6, and then rotate the stabilizing nut 11 until the mounting block 15 moves into the clamping groove 16, so that the movable side plates 2 are stably mounted on the bottom plate 1 and the end plate 3. Thus, the position of the movable side plates 2 mounted on the bottom plate 1 and the end plate 3 can be adjusted according to the required thickness of the concrete guardrail, effectively improving the practicability of the precast formwork.

[0020] During use, the operator places the two movable side plates 2 along the opposite sides of the end plate 3 according to the thickness of the concrete guardrail to be fabricated, so that the distance between the two movable side plates 2 is the thickness of the concrete guardrail. Rotate the adjusting nut 14. The adjusting nut 14 makes the adjusting screw 13 extend through the threaded connection with the adjusting screw 13. The adjusting screw 13 drives the mounting block 15 to move until the mounting block 15 moves to the clamping block 6. Then rotate the stabilizing nut 11. The stabilizing nut 11 moves downward along the surface of the threaded bolt 10 until the stabilizing nut 11 contacts the top of the L-shaped plate 7. The stabilizing nut 11 drives the L-shaped plate 7 to rotate with the connection point with the fixed block 5 as the center of the circle. The L-shaped plate 7 drives the mounting block 15 to move downward until the mounting block 15 moves into the clamping groove 16. Insert the mounting blocks 15 on the bottom plate 1 and the end plate 3 into the clamping grooves 16 on the two movable side plates 2 respectively, so that the movable side plates 2 are stably mounted on the bottom plate 1 and the end plate 3. Then, pour concrete into the two movable side plates 2 to fabricate the concrete guardrail.
