Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, specifically to a novel cantilevered horizontal protective fixing structure. Background Technology

[0002] Cantilevered horizontal protection systems, as temporary protective measures for preventing falls of personnel and objects during construction, have a significant impact on both construction progress and safety due to their safety and ease of construction. Currently, existing cantilevered horizontal protection devices are mainly compatible with two types of building structural systems: steel structure compatible systems and concrete structure compatible systems.

[0003] Steel structure adapter systems typically use upper and lower clamps to fix the system to steel structural members, achieving reliable load-bearing support. However, this type of clamp system relies on the characteristics of steel members and is not suitable for concrete structures. In contrast, concrete structure adapter systems are more complex, mainly using perforated steel plates and post-installed anchors such as expansion bolts or turnbuckles. The fasteners are placed on the exterior facade of the concrete structure, and then load-bearing members are formed by welding square steel or shaped steel poles to the fasteners to achieve overall load transfer. However, this type of structure is prone to damage to the original building structure during dismantling after use, especially requiring reinforcement and repair at the fastener installation locations, leading to additional economic expenditures and extended construction periods.

[0004] Furthermore, traditional concrete-supported systems typically require workers to operate at heights on the exterior facade during the installation of fasteners and load-bearing components, posing significant safety hazards and increasing the risk of falls from heights. Particularly with post-anchoring methods, fasteners are located on the exterior facade, exposing numerous holes after the protective device is removed, necessitating additional sealing and repair. Conversely, with pre-embedded methods, the non-recyclable metal fasteners are prone to corrosion and leakage, impacting the building's lifespan and aesthetic integrity. Additionally, existing concrete cantilever protection systems often require custom-made fasteners and load-bearing components tailored to the specific building facade, resulting in long production cycles, high manufacturing costs, and difficulty in adapting to rapid deployment requirements in diverse construction environments.

[0005] In summary, existing horizontal protection systems for cantilevered concrete structures have many problems, such as vulnerable exterior facades, high construction safety risks, non-recyclable materials, and poor adaptability. There is an urgent need to propose an improved technical solution that is structurally optimized, easy to construct, highly safe, and economically viable, in order to meet the new requirements of modern building construction for cantilevered protection systems.
