There is no need to replace guardrails of different heights. Time and manpower are saved through instant adjustment, which improves construction efficiency.
[0016] 4. The guardrail for construction can prevent the reverse rotation of the gear by setting a ratchet pawl, which can ensure that after the height of the guardrail is adjusted, the gear will not accidentally reverse due to external force or vibration, thereby ensuring the stability and reliability of the guardrail height. The adjusted guardrail height can be automatically locked without the need for additional braking devices, thereby simplifying the structure and reducing costs.
[0017] 5. The guardrail for construction is equipped with reflective strips. In dimly lit environments, such as at night, on rainy days or in areas with insufficient lighting, the reflective strips can reflect vehicle lights or other light sources to make the railings more eye-catching, reminding pedestrians and vehicles of the existence of the railings. For construction carried out at night, the reflective strips can allow construction workers to see the position of the guardrails more clearly and avoid accidental collisions.

Two guardrail assemblies are slidably arranged between the two columns, and an L-shaped plug rod is symmetrically fixedly connected to the side surface of one of the columns, and an insert block is fixedly connected to the side surface of the other column, and two insert holes matching the L-shaped plug rod are symmetrically provided on the surface of the insert block.
[0032] The guardrail assembly includes a tooth plate, an L-shaped connecting block, a telescopic railing and a vertical plate. The inner wall surface of each column is slidably connected to two tooth plates, the surface of each tooth plate is fixedly connected to an L-shaped connecting block, the surface of the L-shaped connecting block is fixedly connected to a vertical plate, and the telescopic railing is fixedly connected between the two vertical plates on the same side of the two columns.
[0033] The telescopic railing includes a hollow outer rod, an inner rod and a limit slider. The inner rod is inserted in the hollow outer rod. The surface of the inner rod is symmetrically fixedly connected with the limit slider. The limit slider is inserted in the inner wall of the hollow outer rod. The limit slider is slidably connected to the hollow outer rod, and the inner rod is slidably connected to the hollow outer rod through the limit slider.
[0034] A plurality of reflective strips are evenly spaced on the surface of each column.
[0035] The working principle of this embodiment: when using this guardrail, first determine the number of guardrails to be used according to the actual requirements of the construction site, and then install the guardrail. First, determine the length of a single guardrail. When adjusting, two construction workers each hold a column, and then adjust the length of the guardrail by adjusting the spacing between the two columns. In this process, the telescopic railing can be adaptively adjusted according to the spacing between the two guardrails. There is no need to prepare guardrails of various specifications for different length requirements. Through the extensible design, a set of guardrails can meet various length requirements, reducing the cost of purchasing and stockpiling guardrails of different specifications. The length can be adjusted according to actual conditions in different construction projects, which improves the reuse value of the guardrail. After the length of the guardrail is determined, the mounting base plate can be fixed by bolts, and then the guardrail is fixed, and then the subsequent guardrails are fixed according to the above steps, and before fixing, the two adjacent guardrails are spliced by the cooperation of the L-shaped plug rod and the plug block to maintain the integrity of the guardrail and improve the protective effect of the guardrail.
[0036] Embodiment 2
[0037] This embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figures 1 to 10 A T-shaped slider is fixedly connected to the surface of each tooth plate. The T-shaped slider is inserted into the inner wall of the column. The T-shaped slider is slidably connected to the column.
[0038] The inner wall surface of each column is rotatably connected with a gear, a telescopic rotating rod is fixedly connected between the two gears, the telescopic rotating rod is rotatably connected with the two columns respectively, the surface of each gear is meshed with two tooth plates, and the moving directions of the two tooth plates are opposite.
[0039] One end of the telescopic rotating rod passes through one of the columns and is fixedly connected to a hand wheel arranged outside the column. The other end of the telescopic rotating rod passes through another column and extends to the outside of the column and is fixedly connected to a ratchet arranged outside the column. A rotating shaft is fixedly connected to the surface of the column above the ratchet. A ratchet is rotatably connected to the surface of the rotating shaft. The bottom end of the ratchet is placed between the teeth of the ratchet.
[0040] It should be noted that the structure of the telescopic rotating rod is the same as that of the telescopic railing.
[0041] The working principle of this embodiment: during use, when the height of the guardrail needs to be adjusted, the user can turn the hand wheel, and the rotation of the hand wheel will drive the telescopic rotating rod to rotate accordingly, and the rotation of the telescopic rotating rod will drive the two gears to rotate synchronously. The synchronous rotation of the two gears can enable the two tooth plates to move between the two columns, and then drive the vertical plates to move, so that the guardrail assembly can be moved as a whole, and then the relative positions of the two guardrails can be adjusted, so as to change the height of the guardrail, and can quickly switch between different heights to adapt to the changing requirements of the guardrail height in different stages and different working environments in construction. There is no need to replace guardrails of different heights. Time and manpower are saved through instant adjustment, and construction efficiency is improved. Then, the above steps are repeated to adjust the height of the subsequent guardrails. The height of each guardrail can be adjusted individually according to actual use needs to adapt to different construction needs.
[0042] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
