Construction process for conical shell and platform at top of silo
The construction technology for the top conical shell and the platform of the silo comprises the following steps of pre-burying and pouring of a cantilever scaffold sleeve, erecting of the cantilever scaffold, construction of a lower ring beam steel bar structure, pre-burying and pouring of a main cable lifting ring and an auxiliary cable lifting ring, installation of an orthogonal cable net, laying of a steel pipe frame, erecting of a full space supporting frame and installation of the top conical shell and a platform formwork. Pouring for several times, and finally dismantling. The orthogonal cable net formed by installing the steel wire ropes through the main cable hanging rings and the auxiliary cable hanging rings is used as a bearing structure, the steel pipe frame is laid on the bearing structure, the full space supporting frame is erected on the bearing structure, the top conical shell and the platform formwork can be conveniently installed, and graded pouring is achieved. Compared with the prior art, the steel consumption of the supporting system is less, the investment of the steel pipe scaffold is less, the mounting and dismounting construction difficulty is small, the transportation cost is low, the construction period is greatly shortened, the labor cost is further reduced, and the supporting system has good safety benefits, economic benefits and social benefits and is worthy of being vigorously popularized.
本发明一种筒仓顶部锥壳及平台的施工工艺，包括以下步骤：悬挑脚手架套管预埋与浇注，悬挑脚手架搭设、下环梁钢筋结构施工、主索吊环和副索吊环预埋和浇注，安装正交索网，铺设钢管架，搭设满堂支撑架，安装顶部锥壳及平台模板，分次浇注、最后拆除。本发明利用主索吊环和副索吊环安装钢丝绳形成的正交索网作为承重结构，在承重结构上铺设钢管架并搭设满堂支撑架，方便安装顶部锥壳及平台模板，实现分次浇注，这种在正交索曲面网上搭设锥壳模架支撑体系，使得支撑体系钢材用量较现有技术更少，钢管脚手架投入少、安装拆卸施工难度小，运输成本低，大大缩短了工期，进而降低了人工成本，有着良好的安全效益、经济效益及社会效益，值得大力推广。
