北京市机械施工公司在承担北京西四羊肉口内地质部礼堂屋顶结构工程任务中,限于工程四周均是建筑物,场地窄小无法使用机械进入安装,他们因地制宜采用巧妙的施工工艺克服了困难,通过事先预设在柱顶及圈梁上的38kg/m钢轨做滑道,于工程物头一间位置搭设一操作平台,在高空逐间将屋盖组装后,运用滑轮卷扬机组,将屋盖连续拽引至设计位置进行就位安装,首次创造了用简易工艺进行高空水平滑移整体
When Beijing Mechanical Construction Co., Ltd. undertook the task of roof structure engineering of the Beijing Xishou Meat In-Geo-geology Department’s auditorium, it was limited to buildings all around the project. The site was too narrow to use machinery to enter the installation. They used ingenious construction techniques to overcome difficulties through local conditions. Predetermined on the top of the column and ring beam 38kg / m rails as a slide, set up an operating platform at a position in the project head, in the air after the roof was assembled, the use of pulley hoisting unit, the continuous roof拽Introduced to the design position to install in place, for the first time created a simple process for high-altitude horizontal slip overall
