一、塔身支座改进原因某建筑工地1台QTZ125型塔式起重机(以下简称塔机)在完成塔机基础施工后,建设方对建筑物结构进行了变更。经测算,若在该基础的预埋支座上安装塔身,在该建筑物完工后拆卸塔机时,其起重臂将不能顺利避开建筑物,从而给拆卸工作带来困难。二、确定改进方案该塔机基础与建筑物之间位置关系如图1所示。为了确保建筑物完工后可将塔机顺利拆卸下来,经研究提出3种备选
First, the tower body bearing improvement reasons A construction site 1 QTZ125 tower crane (hereinafter referred to as tower crane) in the completion of tower crane foundation construction, the construction side of the building structure has been changed. It has been calculated that if the tower is installed on the foundation prefabricated support and the tower crane is disassembled after completion of the building, the boom will not be able to avoid the building without difficulty, which will make the disassembly difficult. Second, determine the improvement program The tower crane foundation and the location of the relationship between the buildings shown in Figure 1. In order to ensure the completion of the building after the tower crane can be successfully removed, the study proposed three options
