摘要
将塔吊安装于既有框架建筑顶部,在塔吊底部设计钢梁承担重力荷载;塔身与原屋盖梁板连接,主要承担倾覆力矩。通过力学方法详细计算分析出钢梁内力情况并进行钢梁设计,同时做好钢梁与框架柱的连接措施,对原建筑的影响亦需验算。
If a tower crane is located at the top of a frame structure, the steel beams will be installed under the crane to undertake its weight. The body of the crane shall be connected with the original beams and slabs of the roof. The overturning moment of the crane will be counteracted. The internal force of the steel beams will be analyzed by exact mechanical method. By the results the correct type of steel beams will be chosen. At the same time the correct connection between the framework columns and the steel becuns will be ensured. Furthermore, the influence of this crane on the original building is also considered and calculated.
