Abstract

The invention provides a construction method for installing a cantilever protection platform structure on a peripheral reversed beam of a super high-rise building. The construction method comprises the steps that an upper hanging ring and a lower pressing ring are pre-buried; mounting a cantilever steel beam; laying a bottom layer for protection; laying upper layer protection; peripheral protection is installed; and an anti-overturning brick buttress is constructed. According to the construction method, in the construction process, the overhanging protective shed can be directly installed on the reversed beam on the periphery of the super high-rise building, holes do not need to be reserved in the beam, the risk that the rear end of the overhanging steel beam is unstable and overturns is avoided, the overall structure is safe and reliable, a multi-layer protective structure is designed, falling heavy objects are not prone to penetrating through, and the construction efficiency is improved. Personal safety of constructors can be effectively guaranteed, construction is convenient and fast, the appearance is neat and attractive, and meanwhile large economic benefits and social benefits are achieved.

本发明提供了一种超高层建筑外围反梁上安装悬挑防护平台构造的施工方法，包括：上部吊环及下部压环预埋；悬挑钢梁安装；铺设底层防护；铺设上层防护；安装外围防护；施工防倾覆砖砌支墩。本发明所述的施工方法在施工过程中，可直接在超高层建筑外围上反梁上安装悬挑防护棚，不需要在梁内预留孔洞，避免了悬挑钢梁后端失稳倾覆风险，整体构造安全可靠，而且本发明设计有多层防护结构，坠落重物不易贯穿，能够有效确保施工人员的人身安全，施工方便快捷，外观整洁、美观的同时，具有较大的经济效益和社会效益。
