Description

Technical Field

[0001] The present invention relates to the technical field of building construction equipment, and in particular to a novel cantilevered horizontal protective fixed structure and a construction method thereof. Background Art

[0002] As a temporary protection measure for preventing people and objects from falling during construction, cantilevered horizontal protection systems have a significant impact on both construction progress and safety, both in terms of safety and ease of construction. Currently, existing cantilevered horizontal protection systems are primarily compatible with two types of building structures: steel structures and concrete structures.

[0003] Among them, steel structure adaptation systems are typically fixed to steel structural members through upper and lower clamps to achieve reliable load support for the system. However, the structural form of this type of clamp system relies on the characteristics of steel members and is not suitable for concrete structures. In comparison, the form of concrete structure adaptation systems is more complex, mainly using perforated steel plates and post-installed anchors such as expansion screws or basket bolts. The fixings are set on the facade of the concrete structure, and then the vertical square steel or steel sections are welded to the fixings to form a load-bearing member to achieve overall force transmission. However, during the dismantling process after use, this type of structure is prone to damage to the original building structure, especially the need for reinforcement and repair at the fixing installation site, resulting in additional economic expenses and extended construction time.

[0004] Furthermore, traditional concrete adaptation systems often require workers working at height to work on the exterior facade of the structure during the installation of fixtures and load-bearing components. This poses significant safety risks during construction and is prone to accidents such as falls from height. In particular, with post-anchoring, the fixtures are installed on the exterior facade of the structure. Removal of the protective devices exposes numerous holes, requiring additional sealing and repair. With pre-embedded systems, metal fixtures cannot be recycled, leading to rust and leakage, which can affect the building's service life and appearance. Furthermore, the fixtures and load-bearing components of existing concrete structure cantilever protection systems often require custom-made components tailored to the specific building facade. This not only results in long production cycles and high manufacturing costs, but also makes it difficult to adapt to the rapid deployment requirements of diverse construction environments.

[0005] In summary, the existing cantilever horizontal protection system for concrete structures has many problems, such as the fragility of the structural facade, high construction safety risks, non-recyclable materials and poor adaptability. It is urgent to propose an improved technical solution with structural optimization, convenient construction, high safety and good economic efficiency to meet the new requirements for cantilever protection systems in modern building construction.
