Description

Technical Field

[0001] This application belongs to the field of building construction technology, and in particular relates to a reusable telescopic opening protection device. Background Technology

[0002] In current construction projects, the requirements for building functionality and aesthetics are increasing. In structural design and construction, many temporary or permanent openings are reserved to meet the requirements of construction or subsequent equipment installation. However, these reserved openings also bring safety risks such as falls from heights and falling objects. Therefore, how to effectively protect openings is one of the main issues to be considered in current construction.

[0003] The existing main protection methods include steel pipe guardrail enclosure, tool-type guardrail enclosure, ground-mounted protective frame platform, and wooden formwork enclosure. Steel pipe guardrail and tool-type guardrail are insufficient for horizontal protection against falling objects from heights, have high wear and tear, and are costly. Protective frame platforms need to be erected from the first floor to the top floor of the building, which is complicated to build and requires a large amount of steel pipes and other materials, making it uneconomical. Wooden formwork enclosure has limited structural strength, low adaptability to various sizes of reserved openings, and is not reusable.

[0004] For example, a patent application (CN202411466541.3) discloses a telescopic opening protection device, comprising a support frame and a panel. The support frame is a rectangular frame composed of four interconnected telescopic rods, and its size can be changed by extending or retracting the rods. The panel is installed on top of the support frame and consists of four stacked and slidably connected cover plates. The panel can be unfolded by sliding the four cover plates to form a rectangular panel structure adapted to the size of the support frame. In use, this device allows for the adjustment of the support frame size by extending or retracting the telescopic rods and the panel size by sliding the four cover plates, thus protecting openings of different sizes. It has a wide range of applications, is reusable, and avoids material waste.

[0005] The corresponding device forms a rectangular panel structure that matches the size of the support frame by sliding and unfolding four cover plates. The limitations of the cover plate area and weight severely affect the adaptability and ease of reuse of the device. Summary of the Invention

The sliding steel plate 7 can slide in the extension direction of the support steel plate 6, thereby adapting to different opening lengths and widths.

[0030] When protecting the opening, each telescopic rod 4 extends or shortens to allow each supporting steel plate 6 to abut against the reserved opening edge 2; each sliding steel plate 7 adjusts its position to cover the corresponding reserved opening edge 2. Furthermore, in the telescopic opening protection device, several parallel ropes 11 are arranged between each parallel supporting steel plate 6, and several parallel ropes 11 are arranged between each parallel movable steel plate, thus forming an interwoven rope mesh structure. This rope mesh structure completes the protection of the corresponding opening.

[0031] Preferably, the supporting steel plate 6 has an L-shaped structure, and the inside corner of the L-shaped structure of the supporting steel plate is engaged with the edge of the reserved opening at the opening to be protected.
