Inverted type cantilever scaffold erecting method
The invention provides an inverted type cantilever scaffold erecting method. The method comprises the following steps of 1) erecting a first-step frame of an upper-layer scaffold, wherein the first-step frame of the upper-layer scaffold is pre-erected on a lower-layer scaffold, so that the bottom end of a cantilever vertical rod in the first-step frame is higher than a cantilevered floor; 2) pre-embedding anchoring parts in the cantilevered floor, wherein the anchoring parts are pre-embedded according to the mounting position of a cantilever steel beam; 3) installing the cantilever steel beam,wherein the cantilever steel beam is installed through the anchoring parts, and a positioning support is installed on the cantilever steel beam; 4) releasing the first-step frame to the cantilever steel beam, wherein after the cantilever steel beam is installed, the cantilever vertical rod is lowered onto the cantilever steel beam and positioned with the positioning support; 5) erecting an upper-layer frame body of the upper-layer scaffold, wherein after the first-step frame is loosened, the upper-layer frame body of the upper-layer scaffold is erected according to a conventional lapping method. According to the erecting method, the great potential safety hazard of mounting protection missing of the cantilever steel beam is eliminated, the safety protection of the cantilever layer frame body is achieved by 100% in place, and the safety performance of the cantilever layer frame body is effectively guaranteed.
一种逆作式悬挑脚手架搭设方法，包括以下步骤：1）搭设上层脚手架的首步架：在下层脚手架上预先搭设上层脚手架的首步架，使首步架中悬挑立杆的底端高出悬挑层楼面；2）在悬挑层楼面预埋锚固件：根据悬挑钢梁的安装位置预埋锚固件；3）安装悬挑钢梁：通过锚固件安装悬挑钢梁，在悬挑钢梁上安装定位支座；4）放松首步架至悬挑钢梁：悬挑钢梁安装好后，将悬挑立杆降落到悬挑钢梁上并用定位支座定位；5）上层脚手架的上层架体搭设：放松首步架后，按照常规搭设方法搭设上层脚手架的上层架体。本发明搭设方法消除了悬挑钢梁安装防护缺失的重大安全隐患，实现了悬挑层架体安全防护100%到位，有效保证了悬挑层架体的安全性能。
