Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a construction scaffold with a wind-resistant and stable structure. Background Technology

[0002] Cantilever scaffolding is a simple facility used in construction, divided into single-layer and multi-layer cantilever types. It's a technical term in construction, referring to a building component achieving an effect using cable-stayed or other structural elements. Part or all of the building is constrained at one end, making it a geometrically invariant system, while the other end is unconstrained. This gives a sense of instability. It primarily bears lateral forces, unlike suspended structures. Cantilever structures are a common structural form in engineering, such as canopies, eaves, balconies, and corridors in building construction. This type of structure involves cantilevering beams or slabs from the main structure, forming a cantilever structure, but it is essentially still a beam-slab structure.

[0003] However, traditional I-beam scaffolding has a relatively simple structure and lacks wind-resistant mechanisms. When encountering strong winds outdoors, it is easily damaged. Furthermore, the wind-resistant mechanism is troublesome, time-consuming, and labor-intensive to install, affecting construction efficiency.
