Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to an adjustable protective device for edge openings. Background Technology

[0002] Protecting openings and edges is a crucial aspect of construction safety, aiming to prevent falls from heights and ensure the safety of workers and other personnel on site. All openings in construction projects (such as reserved openings, stairwells, elevator shafts, and passageways) must be protected to prevent falls or being struck by objects.

[0003] In the traditional process of protecting openings near the edge, a fixed fence is usually installed on the outside of the opening. During the later decoration process, the fence needs to be dismantled first, then the height of the fence needs to be increased, and finally, holes need to be drilled again to fix the fence a second time. This construction method is relatively laborious and affects the convenience of construction, and needs to be improved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an adjustable protective device for edge openings, which improves the convenience of construction.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adjustable protective device for edge openings, comprising: Pre-embedded bolts are embedded in the building wall and located on both sides of the adjacent opening; The mounting plate has a U-shaped cross-section and is vertically installed on both sides of the adjacent opening. The upper and lower ends of the mounting plate are provided with mounting holes for the pre-embedded bolts to pass through. A nut, threadedly connected to the pre-embedded screw, and presses against the mounting plate; An adjusting rod extends horizontally through the mounting plate, which has a row of adjusting holes for the adjusting rod to pass through. A protective fence is installed at the edge of the opening, and the protective fence is equipped with hooks to hook the adjusting rod.

[0006] In a preferred embodiment, the present invention can be further configured such that both ends of the adjusting rod are provided with elastic locking pins that abut against the sides of the mounting plate.

[0007] In a preferred embodiment, the present invention can be further configured such that the lower end of the protective fence is provided with a support foot that abuts against the outer side of the building wall.

[0008] In a preferred embodiment, the present invention can be further configured such that: the support leg is rotatably connected to the protective fence, and the protective fence is provided with a locking rod for penetrating the support leg when the support leg is in a horizontal state.

[0009] In a preferred embodiment, the present invention can be further configured such that: the support leg includes a tube, a rod, and a pad; the tube is rotatably connected to the protective enclosure; the rod is threadedly connected to the tube; and the pad is disposed at the end of the rod and is used to abut against the outer side of the building wall.

[0010] In a preferred embodiment, the present invention can be further configured such that a warning light strip is provided at the upper end of the protective fence.

[0011] In summary, this utility model has the following beneficial effects: 1. By setting up suspended and fixed protective barriers at the edge openings, the protective devices can be quickly installed, fixed, and easily disassembled and transported. At the same time, the height of the protective barriers can be adjusted quickly to meet the needs of later decoration work and improve the convenience of construction. 2. By setting up folding feet at the lower end of the protective fence that abut against the outside of the building wall, the protective fence is firmly attached to the building wall, preventing it from shaking and increasing its stability during use.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings.

[0015] like Figure 1 , Figure 2 As shown, an adjustable protective device for edge openings includes a pre-embedded bolt 1, a mounting plate 2, a nut 3, an adjusting rod 4, and a protective barrier 5.

[0016] like Figure 1 , Figure 2As shown, the pre-embedded bolt 1 is embedded in the building wall and located on both sides of the adjacent opening. The mounting plate 2 has a U-shaped cross-section and is vertically installed on both sides of the adjacent opening. The upper and lower ends of the mounting plate 2 are provided with mounting holes 21 for the pre-embedded bolt 1 to pass through. The nut 3 is threaded to the pre-embedded bolt and presses the mounting plate 2 tightly.

[0017] like Figure 1 , Figure 2 As shown, the adjusting rod 4 horizontally passes through the mounting plate 2, and the mounting plate 2 is provided with a row of adjusting holes 22 for the adjusting rod 4 to pass through. Both ends of the adjusting rod 4 are provided with elastic locking pins 41 that abut against the sides of the mounting plate 2 to lock the adjusting rod 4.

[0018] like Figure 1 , Figure 2 As shown, the protective fence 5 is installed at the edge of the opening. The protective fence 5 is equipped with S-shaped hooks 6, the upper end of which is hooked to the adjusting rod 4, and the lower end of which is hooked to the protective fence 5. A warning light strip 51 is installed at the upper end of the protective fence 5 to remind workers at night and ensure construction safety.

[0019] When protection of the edge opening is required, the mounting plate 2 is fitted onto the pre-embedded bolt 1, and then the nut 3 is tightened to press the mounting plate 2 into place. Then, the adjusting rod 4 is removed and horizontally inserted through the required adjusting hole 22, allowing for free selection of the height of the adjusting rod 4.

[0020] Then, take out the protective fence 5, first hook the hook 6 onto the adjusting rod 4, and then hang the protective fence 5 on the hook 6. Use the weight of the protective fence 5 itself to make the protective fence 5 hang down naturally, and achieve the coverage and protection of the edge opening.

[0021] When the decoration is carried out later, the height of the protective fence 5 needs to be provided. At this time, the protective fence 5 and the hook 6 are removed and unhooked. Then, the adjusting rod 4 is pulled out and inserted into the required adjusting hole 22 above to adjust the height of the adjusting rod 4. After the protective fence 5 is hung, the bottom height of the protective fence 5 can also be quickly adjusted, improving the convenience of construction.

[0022] like Figure 1 , Figure 3 As shown, the lower end of the protective fence 5 is provided with a support leg 7 that abuts against the outside of the building wall. The support leg 7 is rotatably connected to the protective fence 5. The protective fence 5 is provided with a locking rod 52 for passing through the support leg 7 when the support leg 7 is in a horizontal state.

[0023] like Figure 3As shown, the support leg 7 includes a tube body 71, a rod body 72, and a pad 73. The tube body 71 is rotatably connected to the protective enclosure 5, the rod body 72 is threadedly connected to the tube body 71, and the pad 73 is located at the end of the rod body 72 and is used to abut against the outside of the building wall.

[0024] After the protective fence 5 hangs down naturally, first control the support leg 7 to rotate to a horizontal position. Then tighten the locking rod 52 so that it engages with the tube 71 on the support leg 7, thus fixing the support leg 7 horizontally. Next, rotate the rod 72 so that the pad 73 contacts the outside of the building wall, providing support for the protective fence 5 and ensuring that the protective fence 5 is firmly against the building wall, preventing it from swaying and increasing its stability during use.

[0025] When the protective fence 5 needs to be transported, the locking lever 52 can be loosened, and then the support leg 7 can be flipped to a vertical position to achieve the hidden storage of the support leg 7, which facilitates the stacking and transportation of the protective fence 5.

[0026] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
