Description

Technical Field

[0001] The present invention relates to the technical field of building guardrails, and in particular to a construction guardrail for construction engineering and a protection method thereof. Background Art

[0002] During highway construction, the safety of construction workers is of paramount importance. To prevent people outside the construction area from accidentally entering the area and to protect construction workers from potential hazards during construction (such as falls from heights and splashing objects), construction guardrails have become an indispensable safety feature. However, traditional construction guardrails have the following problems: First, the height of traditional guardrails is not adjustable. They are fixed and cannot be adjusted to the actual conditions of the construction site (such as terrain changes or construction areas at different heights), limiting their applicability and flexibility. Second, the guardrails are difficult to move as a whole. Due to their large size and weight, moving them to other construction areas often requires the collaboration of multiple people or the use of mechanical equipment, increasing workload and safety risks. Summary of the Invention

[0003] The present invention is aimed at the above-mentioned problems and specifically designs a construction guardrail and a protection method for construction projects, which increases the adjustability of the guardrail height and uses pulleys to achieve easy transfer of the guardrail.

[0004] To achieve the above-mentioned purpose, the present invention provides a construction guardrail for construction projects, comprising a crossbeam rod 1, and sealing blocks symmetrically arranged at both ends of the crossbeam rod 1, the bottom end of the sealing block is fixedly connected to an extension column, the extension column is plugged into a column, the column is fixedly arranged on the top surface of a pad, a crossbeam rod 2 is fixedly connected between the two columns, a movably plug-in sleeve and a guardrail rod are arranged between the crossbeam rod 1 and the crossbeam rod 2; the extension column is fixedly connected to a support plate, the support plate is threaded with a hand screw, the hand screw passes through the support plate and is threadedly connected to the column; the support plate passes through the pad through a through hole, and a pulley is installed at the bottom of the support plate.

[0005] Furthermore, the side wall of the support plate is provided with a threaded hole, and the side wall of the column is provided with multiple positioning holes. The threaded holes and the positioning holes are matched with the hand screws, and the hand screws are threadedly connected to the threaded holes and the positioning holes in sequence. The multiple positioning holes are arranged in a linear array along the height direction of the column.

[0006] Preferably, the column is a hollow square tube structure, and the height of the extension column is greater than the height of the column.

[0007] Furthermore, an embedding groove is provided at the bottom end of the support plate, and a limiting shaft is rotatably connected between two opposite side walls of the embedding groove. The pulley is sleeved on the limiting shaft, and the pulley protrudes from the embedding groove.

[0008] Furthermore, the pad is a square plate structure, the top surface of the pad covers the bottom surface of the column, and the pad is provided with a completely penetrating countersunk hole, and mounting bolts are installed in the countersunk hole. The pad is fixed to the road surface at the construction site by the mounting bolts.

[0009] Furthermore, the blind hole portion in the countersunk hole is a U-shaped open groove.

[0010] Furthermore, the crossbeam 1 and the crossbeam 2 are arranged in parallel and have the same length, and the plurality of sleeves are arranged in a linear array along the length direction of the crossbeam 1, and the number of the guardrails corresponds to the number of the sleeves.

[0011] Preferably, the support plates are L-shaped and are symmetrically distributed about the extension column.

[0012] Furthermore, the side walls of the support plate are symmetrically provided with weight-reducing holes.

[0013] The present invention also includes a method for protecting a construction guardrail for a building project, comprising the following steps: 1) Use the mounting bolts to fix the pad to the road surface at the construction site. When the enclosure height needs to be adjusted, first unscrew the thumb screws inserted into the positioning holes to release the relative static state of the column and the extension column. Then, hold the sealing block and pull the extension column upward to the required height. Screw back the thumb screws and insert them into the adjacent positioning holes to restore the relative static state of the column and the extension column. 2) In the step 1, when the sealing block is extracted and moved, the sealing block slides based on the guardrail rod through the traction sleeve of the crossbeam rod 1, that is, the height adjustment of the protective structure between the crossbeam rod 1 and the crossbeam rod 2 is achieved; 3) When the guardrail needs to be dismantled and moved around at the construction site, first remove the mounting bolts in the countersunk holes to release the relative static state between the pad and the road surface, then unscrew the thumb screws that were inserted back into the positioning holes. The extension column moves down under its own weight and is inserted into the bottom of the column. Manually lift the pad so that the extension column is fully inserted into the column. At this time, the bend of the support plate overlaps the top surface of the column and the pulley protrudes through the opening. Screw back the thumb screws to complete the anti-slip braking of the column and the extension column, and finally use the pulley to push the guardrail to move.

[0014] In summary, the present invention has the following advantages and beneficial technical effects: 1. The present invention realizes flexible adjustment of the height of the guardrail by designing a retractable extension column and multiple sleeves, which can adapt to construction areas of different heights and improve the applicability and flexibility of the guardrail.

[0015] 2. The present invention provides a pulley and a through-hole on the pad. When the bent portion of the support plate overlaps the top surface of the column, the bottom end of the support plate is inserted into the through-hole, and the pulley surface is below the bottom surface of the pad, so that the guardrail can be easily pushed after removal, reducing the labor during the transportation process and thereby improving work efficiency.

[0016] 3. The present invention adopts the design of hand screws and positioning holes, which makes the disassembly and assembly process of the guardrail simple and quick, without the need for complicated tools and a lot of manpower, thus reducing construction costs and time costs.

[0017] 4. The present invention realizes a stable connection between the upright column and the extension column through the cooperation of the support plate, the hand screws and the positioning holes, ensures the stability of the guardrail installation, and reduces the risk of loosening or collapse.

[0021] like Figure 4 as well as Figure 9 As shown, a threaded hole 10 is opened on the side wall of the support plate 6, and a plurality of positioning holes 11 are opened on the side wall of the column 3. The threaded hole 10 and the positioning holes 11 are matched with the hand screws 12. The hand screws 12 are threadedly connected to the threaded hole 10 and the positioning holes 11 in sequence. The plurality of positioning holes 11 are arranged in a linear array along the height direction of the column 3.

[0022] like Figure 5-Figure 9As shown, the column 3 is a hollow square tube structure, and the extension column 4 is the same height as the column 3. The bottom surface size of the sealing block 5 is equal to the top surface size of the column 3. The bottom end of the support plate 6 is provided with an embedding groove 7. A limit shaft 8 is rotatably mounted between the two opposite side walls of the embedding groove 7. A pulley 9 is mounted on the rod body of the limit shaft 8 and protrudes downward from the embedding groove 7.
