Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically, to an auxiliary quick dismantling device for the inner wall of a cantilevered external frame. Background Art

[0002] Cantilever scaffolding is a commonly used form of external scaffolding for high-rise buildings today. The reasonable optimization of the embedded ring at the cantilever anchor end of the cantilever external frame provides support for the safe, economical, fast and efficient construction of high-rise buildings. The existing embedded anchor rings are made of ordinary round steel and directly embedded into the structural plate after processing. The embedded rings are usually placed under the steel bars at the bottom of the structural plate. After the structure is cast, the embedded ring steel bars at the bottom of the plate are exposed, posing a hidden danger of water seepage. Moreover, the embedded ring protrudes from the structural plate surface after the cantilever scaffolding is dismantled and must be cut off before the floor is cast. Cutting the steel bars is usually time-consuming and laborious. The steel bar heads after cutting cannot be reused and can only be used as waste steel bars. If the embedded rings are not cut off in time, there will be a major safety hazard during the construction process.

[0003] In the construction of high-rise buildings, cantilevered scaffolding plays a vital role as a supporting and protective structure. However, as the project progresses, the final dismantling of the cantilevered scaffolding has become a technically complex and high-risk task. The cantilevered scaffolding dismantling method mainly relies on manual operation. During the dismantling process, since the I-beam is an integrated structure and has a large weight, the impact force of the drop is large when it is directly dismantled, resulting in a great safety hazard during dismantling. Therefore, it is particularly important to develop a device that can assist in the rapid and safe dismantling of the inner wall of the cantilevered scaffolding. Utility Model Content
