Construction method of support-free cantilever platform
The invention discloses a construction method for a support-free cantilever platform. The construction method comprises the following steps that firstly, a building main body structure is constructed to the position above the elevation of the cantilever platform; secondly, an operation platform is erected below the elevation position of the cantilever platform; thirdly, after construction of the operation platform is completed, an auxiliary support is erected at the elevation position of the cantilever platform; fourthly, after the auxiliary supports are erected, cantilever beam formworks are hoisted at the bottoms of the auxiliary supports, and cantilever beams are poured; fifthly, after the cantilever beam is poured, a prefabricated cantilever platform bottom plate is fixedly installed on the top of the cantilever beam; and 6, after the cantilever platform bottom plate is installed, a floor slab is poured on the cantilever platform bottom plate, after construction of the cantilever platform is completed, the operation platform and the auxiliary support are dismantled, and construction is completed. According to the construction method, the bearing requirement of construction of the ultra-large cantilever platform can be met, the construction procedure is simplified, the construction cost is saved, a complex and tedious supporting frame does not need to be built, and the structure of the cantilever platform cannot be damaged.
本发明公开了一种免支撑悬挑平台施工方法，包括以下步骤：步骤一、将楼房主体结构施工至悬挑平台标高上方位置；步骤二、在悬挑平台标高位置下方搭设操作平台；步骤三、操作平台施工完成后，在悬挑平台标高位置搭设辅助支架；步骤四、辅助支架搭设完成后，在辅助支架底部吊装悬挑梁模板，浇筑悬挑梁；步骤五、悬挑梁浇筑完成后，在悬挑梁顶部固装预制的悬挑平台底板；步骤六、悬挑平台底板安装好后，在悬挑平台底板上浇筑楼板，悬挑平台施工完成后，拆除操作平台和辅助支架，施工结束。本发明可满足超大型悬挑平台施工的承载要求，简化了施工工序，节省了施工成本，无需搭建复杂、繁琐的支撑架，不会对悬挑平台自身结构造成损伤。
