由于高层建筑的发展,固定式塔机日趋增多。目前,固定式塔机主要有两种方法:一、埋设基础节法,具有运输量少,占地面积小,可利用建筑物基础等特点,受到广大施工单位的欢迎。二、中心压重法,适用于安装使用频繁的施工工程。下面我们对预埋基础节法作简单介绍。在塔机基础的施工中,应保证基础砼的质量和基础节四主肢杆端面高度差小于设计许用值。否则,将造成塔机倾斜,甚至倾覆。QTZ60型固定式塔机设计要求基础节
Due to the development of high-rise buildings, fixed tower crane is increasing. At present, the fixed tower crane has two main methods: First, laying the foundation of the festival, with less traffic, small footprint, the basis of the available buildings and other characteristics, by the majority of construction units welcome. Second, the center of gravity method, suitable for installation and frequent construction projects. Below we have a brief introduction of embedded base method. In the tower crane foundation construction, should ensure that the quality of foundation concrete and the base section of the four limbs height difference is less than the design allowable value. Otherwise, it will cause the tower crane to tilt or even topple. QTZ60 fixed tower crane design requirements based section
