Mounting and dismounting method for lower supporting type cantilever I-shaped steel platform
The invention discloses a method for mounting and dismounting a lower supporting type cantilever I-shaped steel platform, which comprises the following steps of: S1, reserving a U-shaped anchor ring for pre-embedding and anchoring a cantilever I-shaped steel main body in advance when concrete of a cantilever I-shaped steel laying layer is poured in a building construction site in the earlier stage, when the lower supporting rod piece supporting layer concrete is poured, a first lower supporting rod piece connecting plate is reserved and embedded in advance; and S2, a tower crane lifting lug, a positioning short steel bar head, a lifeline and a second lower supporting rod piece connecting plate are installed on the upper portion of the cantilever I-shaped steel body in advance, the lower supporting rod piece body and the second lower supporting rod piece connecting plate are connected through bolt connection, and connection between the cantilever I-shaped steel body and the lower supporting rod piece body is completed. The lower supporting type cantilever I-shaped steel platform of the lower supporting type cantilever scaffold has the beneficial effects that the problems of mounting and dismounting of the lower supporting type cantilever I-shaped steel platform of the lower supporting type cantilever scaffold that counter-pulling measures cannot be taken above a structure with a long cantilever distance, no operation platform is arranged below the cantilever platform, and the lower supporting rod piece and the cantilever I-shaped steel are difficult to connect are solved.
本发明公开了一种下撑式悬挑工字钢平台的安装拆除方法，所述方法包括：S1、前期在建筑施工场地内浇筑所述悬挑工字钢铺设层混凝土时提前预留预埋锚固悬挑工字钢主体用的U型锚环，浇筑所述下撑杆件支撑层混凝土时提前预留预埋一号下撑杆件连接板；S2、所述悬挑工字钢主体上部提前安装塔吊吊运用吊耳、定位短钢筋头、生命线和二号下撑杆件连接板，所述下撑杆件主体和二号下撑杆件连接板通过螺栓连接进行连接，完成悬挑工字钢主体与下撑杆件主体之间的连接。本发明的有益效果是：解决了悬挑距离较长结构上方无法设置反拉措施，悬挑平台下方无操作平台，下撑杆件与悬挑工字钢连接困难的下撑式悬挑脚手架的下撑式悬挑工字钢平台的安装和拆除的问题。
