Description

Technical Field

[0001] This utility model relates to the field of building-related technology, specifically to a parapet for engineering construction. Background Art

[0002] During construction, to improve building safety, safety railings are installed around the building to prevent construction workers from accidentally falling. However, existing safety railings still have shortcomings, such as:

[0003] The existing CN115306139B discloses an engineering construction scaffolding; it includes multiple panels and a connecting unit set between two adjacent panels. A first side panel is provided on one side of the panel and a second side panel is provided on the other side of the panel. The outer walls of the first and second side panels are provided with side grooves. The inner wall of the first side panel has an insertion slot. The inner wall of each second side panel is provided with an insertion block that is compatible with the insertion slot. The connecting unit includes a base plate, two uprights and two locking strips. The two uprights are fixedly connected to the base plate and are located on both sides of the base plate. The inner side wall of each base plate is provided with a locking strip, and the locking strip is compatible with the side groove.

[0004] The aforementioned documents allow for temporary adjustments to the width of the parapets based on varying on-site construction environments, offering greater flexibility. However, the stability between adjacent sets of parapets needs improvement during assembly, and the parapets themselves are not flexible enough for adjustment. Therefore, we propose a new type of construction parapet to address these issues. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Please see Figure 1-6 This utility model provides a technical solution: a construction guardrail, comprising a left concave plate 1 and a right concave plate 3. Horizontal bars 2 are fixed to the upper and lower sides of the right end of the left concave plate 1, and a right concave plate 3 is provided on the right side of the left concave plate 1. Fixed guardrails 4 are fixed to the inner sides of both the left and right concave plates 1 and 3. The left concave plate 1 is slidably connected to the inner cavity 18 at the end of the right concave plate 3 via the horizontal bars 2, and the upper and lower ends of the right concave plate 3 are fixedly connected to the horizontal bars 2 via fastening bolts 5. This allows for easy sliding of the left concave plate 1 and, with the use of the fastening bolts 5, adjustment of the construction guardrail. The length of the railing is as follows: the upper and lower sides of the left end of the right concave plate 3 are provided with inner cavities 18; the upper groove 6 of the left concave plate 1 and the lower groove 6 of the right concave plate 3 are provided with slots 15; the lower surface of the upper crossbar 2 of the left concave plate 1 is provided with threaded grooves 11; a movable railing 12 is connected to the threaded groove 11; the lower part of the crossbar 2 is threadedly connected to the movable railing 12, which facilitates the installation and disassembly of the movable railing 12 and the crossbar 2; the lower ends of the left concave plate 1 and the right concave plate 3 are provided with mounting holes 13, and a support rod 14 is threadedly connected to the mounting holes 13.

[0029] Both the left concave plate 1 and the right concave plate 3 have slots 6 on their sides, and each slot 6 has two sets. A rotating disk 7 is provided on the lower surface of the left concave plate 1 and the upper surface of the right concave plate 3. A connecting shaft 8, rotatably connected to the surfaces of the left and right concave plates 1 and 3, is fixed to the middle of the rotating disk 7. A connecting rod 9 is fixed to the surface of the connecting shaft 8, and an arc-shaped rod 10 is provided at the end of the connecting rod 9. The arc-shaped rod 10 is semi-circular, and the connection between the arc-shaped rod 10 and the connecting rod 9 is fixed. Limiting blocks 16 are provided on both sides of the end of the arc-shaped rod 10, and the inner end of the limiting blocks 16 is open to… The spring 17 is connected to the arc-shaped rod 10. The use of the spring 17 at the end of the arc-shaped rod 10 allows the limiting block 16 to bounce at the end of the arc-shaped rod 10. The diameter of the semi-circular upper part of the arc-shaped rod 10 is smaller than the length of the slot 6, which facilitates the rotation of the arc-shaped rod 10 inside the slot 6. The limiting block 16 is set in the shape of a right-angled trapezoid, and the arc-shaped rod 10 is engaged with the slot 15 on the slot 6 on the surface of the left concave plate 1 and the right concave plate 3 through the limiting block 16. The limiting block 16 can be inserted into the slot 15 inside the slot 6 to facilitate the assembly between the two sets of building panels.

[0030] Working principle: First, when in use, the device is installed around the construction site, and support rods 14 are threaded onto the lower ends of the left concave plate 1 and the right concave plate 3 to support the construction of the fence. When assembling the two sets of construction fences, the rotating disk 7 above the right concave plate 3 can be rotated so that the rotating disk 7 drives the connecting rod 9 to rotate through the connecting shaft 8. This causes the connecting rod 9 to drive the arc rod 10 to rotate 90° on the slot 6 on the side of the right concave plate 3. When the arc rod 10 rotates 90°, the right trapezoidal limiting block 16 at the end of the arc rod 10 will engage with the slot 15 inside the slot 6 on the side of the left concave plate 1 on the other side, so as to ensure stable assembly between the two sets of construction fences.

[0031] When the length of the scaffolding needs to be adjusted, the fastening bolt 5 on the inner side of the right concave plate 3 can be rotated, which allows the crossbar 2 of the left concave plate 1 to slide out from the inner cavity 18 at both ends of the right concave plate 3, so that the left concave plate 1 and the right concave plate 3 can be adjusted. Then, the movable railing 12 is threaded into the threaded groove 11 below the crossbar 2, which facilitates the installation of the movable railing 12 after the left concave plate 1 is adjusted, thus facilitating the adjustment of the length of the scaffolding. This is the working principle of the scaffolding used in this construction project.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
