Specific embodiments

[0021] 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 the embodiments.

[0022] Referring to Figures 1 - 4 , a prefabricated and assembled concrete guardrail wall includes a first prefabricated guardrail plate 1. The two ends of the first prefabricated guardrail plate 1 are both provided with a second prefabricated guardrail plate 2 that is slidably connected thereto. Grooves are opened at both ends of the first prefabricated guardrail plate 1. The second prefabricated guardrail plate 2 is located in the groove and is slidably connected to its inner wall. Concrete columns 3 are provided on both sides of the first prefabricated guardrail plate 1. A base 4 is fixedly connected to the bottom of each concrete column 3. Four through holes are provided through the base 4, and the positions of the four through holes are distributed in a rectangular shape. By setting bolts, the base 4 can be installed and fixed to the ground to complete the fixation of the concrete column 3. In this device, the first prefabricated guardrail plate 1, the second prefabricated guardrail plate 2, and the concrete column 3 are prefabricated in a factory and transported to the destination for assembly.

[0023] An alarm light 5 is fixedly connected to the top of each concrete column 3, which can emit warning lights for warning at night. There are two disassembly and assembly mechanisms between each second precast guardrail plate 2 and its corresponding concrete column 3. The disassembly and assembly mechanism includes an L-shaped rod 6 fixedly connected to the side wall of the second precast guardrail plate 2. A fixed block 7 is fixedly connected to the side wall of the first precast guardrail plate 1. A slot 8 is formed in the fixed block 7. The L-shaped rod 6 is inserted into the slot 8. A T-shaped rod 9 is arranged through the fixed block 7 and is slidably connected to it. A spring 10 is sleeved on the outer wall of the T-shaped rod 9. The two ends of the spring 10 are fixedly connected to the fixed block 7 and the T-shaped rod 9 respectively. A limit hole 11 is formed in the L-shaped rod 6. The T-shaped rod 9 is inserted into the limit hole 11. By setting the disassembly and assembly mechanism, the second precast guardrail plate 2 can be assembled and fixed to the concrete column 3. The operation is simple. The disassembly and assembly mechanism can be arranged inside the construction site, and pedestrians outside will not disassemble the guardrail.

[0024] An adjusting mechanism is arranged between the first precast guardrail plate 1 and the two second precast guardrail plates 2. The adjusting mechanism includes a worm 12 that penetrates through the first precast guardrail plate 1 and is rotatably connected to it. A handle 13 is fixedly connected to the top of the worm 12. A protective sleeve is sleeved on the outer wall of the handle 13. The material of the protective sleeve is rubber, which can increase comfort. The worm 12 meshes with two worm wheels 14. A threaded rod 15 is coaxially fixedly connected to both ends of each worm wheel 14. The thread directions of the two threaded rods 15 are opposite, which can make the two second precast guardrail plates 2 move relative to or away from each other. Each threaded rod 15 penetrates through the first precast guardrail plate 1 and is rotatably connected to it. Two threaded grooves 16 are formed on each of the two second precast guardrail plates 2. Each threaded rod 15 is inserted into the corresponding threaded groove 16 and is threadedly connected to it. By setting the adjusting mechanism, the length of the guardrail can be adjusted according to the distance between the two concrete columns 3 to meet different installation requirements.

[0025] In this utility model, the staff transports the prefabricated first prefabricated guardrail plate 1 and the concrete column 3 from the factory to the destination. The base 4 can be installed and fixed to the ground through the cooperation of bolts and through holes, completing the installation and fixation of the concrete column 3. During assembly, the staff holds the handle 13 and rotates it to drive the worm 12, two worm wheels 14, and four threaded rods 15 to rotate, causing the second prefabricated guardrail plates 2 on both sides to move away from each other, enabling the two second prefabricated guardrail plates 2 to slide within the first prefabricated guardrail plate 1 and move towards both sides, thereby adjusting the length of the guardrail to fit the installation and fixation between two concrete columns 3 with different spacings. When assembling, the L-shaped rod 6 is inserted into the fixed block 7, and the staff holds the T-shaped rod 9 and moves it away from the fixed block 7. During this process, the spring 10 is stretched until the L-shaped rod 6 is completely inserted into the slot 8. At this time, the T-shaped rod 9 is released, and under the action of the spring 10, the T-shaped rod 9 is inserted into the limit hole 11 to complete the installation and fixation between the L-shaped rod 6 and the fixed block 7, thus completing the assembly and fixation between the second prefabricated guardrail plate 2 and the concrete column 3.

[0026] Through the adjustment mechanism, this utility model can adjust the lengths of the first prefabricated guardrail plate and the second prefabricated guardrail plate according to the spacing between two columns, solving the problem in the prior art that although the columns need to be installed and fixed according to on-site requirements, once the columns are fixed, the spacings between the columns are different, making it inconvenient to adjust the spacing of the guardrail according to usage needs and resulting in poor flexibility.
