Floating type fan concrete foundation prestress tensioning trolley and construction method
The invention relates to the technical field of draught fan foundation construction, and discloses a floating type draught fan concrete foundation prestress tensioning trolley and a construction method.The tensioning trolley comprises a frame, a hoisting mechanism, a lifting mechanism, a fixing frame and a jack, and the hoisting mechanism is movably installed at the top of the frame; the lifting mechanism is hoisted on the frame and is provided with a lifting platform; the fixing frame comprises a first positioning frame and a second positioning frame, the middle of the first positioning frame is hollow, and the first positioning frame is connected with the frame; the second positioning frame is arranged in the middle of the first positioning frame and connected with the first positioning frame, and a plurality of positioning holes are formed in the second positioning frame; part of the jacks are fixed in the positioning holes, are connected with the second positioning frame and are used for tensioning a middle steel strand of the fan concrete foundation; part of the jacks are used for being fixed to the draught fan concrete foundation and tensioning outer ring steel strands of the draught fan concrete foundation. By means of the method, rapid operation of prestress tensioning construction of the fan concrete foundation can be achieved, and the construction period is shortened.
本发明涉及风机基础施工技术领域，公开了一种漂浮式风机混凝土基础预应力张拉台车及施工方法，张拉台车包括框架、吊装机构、升降机构、固定架以及千斤顶，吊装机构可移动地安装于框架顶部；升降机构吊装于框架上，升降机构具有升降平台；固定架包括第一定位架和第二定位架，第一定位架的中部中空，第一定位架与框架连接；第二定位架设于第一定位架中部且与第一定位架连接，第二定位架上设有多个定位孔；部分千斤顶固定于定位孔且与第二定位架连接，用于张拉风机混凝土基础的中部钢绞线；部分千斤顶用于固定于风机混凝土基础上且张拉风机混凝土基础的外环钢绞线。本发明可实现对风机混凝土基础的预应力张拉施工的快速作业，缩短施工周期。
