Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an edge protection device which is convenient to assemble and disassemble. Background Art

[0002] During the construction of a building structure, it is necessary to reserve openings such as door openings and window openings. Since the door and window openings are located at the edges of the building structure, they need to be protected to ensure the safety of the construction. The edge protection structures of the existing technology are mostly composed of unit bars spliced together. For example, Chinese utility model patent CN216588038U discloses an assembled edge protection railing, which comprises multiple guardrails, multiple fixed locks, multiple fixed latch rods, and connecting hinges. The multiple guardrails can be connected in parallel in sequence through multiple fixed locks. The multiple fixed latch rods are sequentially arranged end to end at the top of the multiple guardrails. The connecting hinge is arranged between two guardrails, and the two guardrails can change the angle between each other through the connecting hinge.

[0003] While existing spliced guardrails can meet the protection requirements of openings of varying shapes and sizes, they are complex in structure, have high material costs, are bulky, and are difficult to transport and store. Furthermore, because the guardrails must be secured to the walls on either side of the opening using tools such as expansion bolts, they can easily cause secondary damage to the finished building structure, requiring later repairs and further increasing construction costs and labor. Therefore, there is a need for an edge protection device that is easily assembled and disassembled, addressing the complex structure, high cost, bulk, and need for expansion bolts used in existing spliced guardrails. Summary of the Invention

[0004] The purpose of the utility model is to provide an edge protection device that is easy to assemble and disassemble, which can solve the problems of the existing technology of complex structure, high cost, large size and need for expansion bolts to fix the spliced guardrails.

[0005] The utility model is achieved in this way:

[0006] A conveniently assembled and disassembled edge protection device comprises an upper support rod, a middle knob rod, a connecting buckle, a lower support rod and a safety rope; the lower part of the upper support rod is adjustably connected to the upper part of the middle knob rod, and the upper part of the lower support rod is adjustably connected to the upper part of the middle knob rod to form an adjustment column; the upper end of the adjustment column abuts the top of the edge hole opening, and the lower end of the adjustment column abuts the bottom of the edge hole opening, and a plurality of adjustment columns are vertically arranged and spaced apart in the edge hole opening; a plurality of connecting buckles are respectively spaced apart on the outer wall of the middle knob rod, and the safety rope is connected between two adjacent adjustment columns through the connecting buckle, and a plurality of safety ropes are horizontally arranged and spaced apart at the edge hole opening.

[0007] The upper support rod is provided with an upper support rod reverse thread on the lower outer wall, the lower support rod is provided with a lower support rod reverse thread on the upper outer wall, and the middle knob rod is provided with a knob rod forward thread on the inner wall, so that the upper support rod is adjustably screwed into the upper part of the middle knob rod through the upper support rod reverse thread and the knob rod forward thread, and the lower support rod is adjustably screwed into the upper part of the middle knob rod through the lower support rod reverse thread and the knob rod forward thread.

[0008] An upper support seat is formed at the upper end of the upper support rod. The upper support seat and the upper support rod are connected to form a T-shaped structure. The top of the upper support seat is fitted against the top of the edge hole.

[0009] The lower end of the lower support rod is formed with a lower support seat, and the lower support seat is connected to the lower support rod to form an inverted T-shaped structure, and the bottom of the lower support seat is fitted against the bottom of the edge hole.
