某高层综合体装配式安全悬挑防护棚在施工中的应用

The Application of Prefabricated Safety Cantilever Protective Shed in a High-Rise Complex

随着社会的发展,城市人口愈加密集,建筑用地日益紧张,建筑高度也在不断突破。在建筑施工中,场地愈发狭窄,场平布置紧凑,高空坠物的事故屡见不鲜。因此,高层建筑主体施工期间,做好高空坠物事故的防护措施十分必要,尤其是临街建筑。随着建筑高度不断增高,传统施工中防高空坠物所采用的安全防护棚也需要更新换代。传统的安全防护棚搭设方式是利用钢管在脚手架上悬挑,然后利用钢丝绳反拉在建筑主体结构上,该方式导致安全防护棚的长度和覆盖面积受到了较大限制,并且影响了脚手架的安全使用。目前,出现了一种将主梁直接附着在主体结构上,通过装配式组装增长了防护长度的新型安全防护棚,有效地提高了防护棚的抗冲击强度及防护面积,有利于确保整个施工环境的安全。该工艺具有拆卸组装方便快捷、施工工期短的优势,有较大的推广意义。

With the development of society, urban population is becoming more and more dense, building land is becoming increasingly tense, and building height is also constantly breaking through. During the construction, the site is becoming narrower,the layout of the site is compact, and the accidents of falling objects from high altitude are common. Therefore, during the construction of the main body of high-rise buildings, it is very necessary to take protective measures against falling objects from high altitude, especially for street buildings. With the increasing height of buildings, the safety protection shed used to prevent falling objects from high altitude in traditional construction also needs to be updated. The traditional way of setting up the safety protection shed is to use steel pipes to suspend on the scaffold, and then use steel wire ropes to pull back on the main structure of the building.This way has greatly limited the length and coverage area of the safety protection shed, and has affected the safe use of the scaffold.At present, there is a new type of safety protection shed that directly attaches the main beam to the main structure and increases the protection length through assembly, which effectively improves the impact strength and protection area of the protection shed and is conducive to ensuring the safety of the entire construction environment. This process has the advantages of convenient disassembly and assembly and shortened construction period, which is of great significance for promotion.
