Chimney platform upside-down construction method
The invention provides a chimney platform upside-down construction method, and belongs to the technical field of building construction. The chimney platform upside-down construction method comprises the steps that a lifting platform is built in advance, a prefabricated top-layer platform component is lifted to the top-layer platform mounting position through the lifting platform, and the lifting platform and a concrete cylinder wall are temporarily locked through a chain block; according to the elevation of a horizontal beam of the top-layer platform, an embedded part of the top-layer platform on the concrete outer cylinder wall is chiseled out, and a cross beam corresponding to the top-layer platform is welded to a set position; a tripod is erected on the lifting platform, and a top-layer platform component, a top-layer inclined support, a top-layer arc-shaped channel steel truss, a top-layer grating plate and a top-layer handrail are sequentially hoisted and installed through a chain block; and after the top-layer platform is installed, a middle-layer platform and a bottom-layer platform are installed in sequence. According to the method, the chimney platform construction from top to bottom is achieved, and the technical effects of being low in construction cost and short in construction period are achieved.
本发明提供一种烟囱平台倒装施工方法，属于建筑施工技术领域，本发明通过预先搭建提升平台，并利用提升平台将预制的顶层平台构件提升至顶层平台安装位置，用手拉葫芦将提升平台与混凝土筒壁临时锁定；根据顶层平台的水平梁的标高，凿出混凝土外筒壁上顶层平台的预埋件，并将顶层平台对应的横梁焊接在设定位置；在提升平台上架设三脚架，利用手拉葫芦依次吊起并安装顶层平台构件、顶层斜支撑、顶层孤型槽钢桁架、顶层格栅板和顶层栏杆；完成顶层平台安装后，依次安装中间层平台和底层平台；本发明实现了自上而下的烟囱平台施工，具有施工成本低，施工周期短的技术效果。
