本发明实施例提供的爬式脚手架100及其爬升方法、装配式建筑的施工方法，通过电动葫芦170控制吊线对所述架体130及其连接的导轨120同步向上提升至指定标高，当电动葫芦170收放吊线时，下提升钢梁150带动架体130及导轨120相对于各楼层的抗倾覆支座110同步向上提升或者同步下降，从而通过电动葫芦170对架体130及导轨120整体升降操作，在架体130及导轨120相对于抗倾覆支座110向上爬升时，无需反复拆装翻转架体130，无需塔吊设备吊装至指定标高，因此，降低了提升难度、施工效率、降低了塔吊在吊装过程中可能导致脱落的安全隐患。
本发明实施例提供的爬式脚手架100及其爬升方法、装配式建筑的施工方法，其中爬式脚手架100在使用时，仅需跨两层建筑结构分层搭建设，相对于传统跨四层建筑的外挂脚手架而言，减少了架体130的整体重量，因此能够减少架体130与建筑结构的连接位置产生裂缝，减少后期修补施工，从而提高了建筑结构的施工质量，降低了施工成本。
本发明实施例提供的爬式脚手架100及其爬升方法、装配式建筑的施工方法，特别适用于装配式建筑结构，当然也适用于传统现场浇筑的建筑结构。
本发明不限于上述具体实施方式，显然，上述所描述的实施例是本发明实施例的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本发明保护的范围。本领域的技术人员可以对本发明进行其他层次的修改和变动。如此，若本发明的这些修改和变动属于本发明权利要求书的范围之内，则本发明也意图包括这些改动和变动在内。
