在大型工业厂房施工中,重型柱的吊装常占着很重要的地位,不仅因它的高度和重量大(达25—60吨),需要重型吊装设备,而且吊装技术复杂、难度大,安装精度要求高,它的吊装顺利与否,常影响着整个吊装工程的质量和进度,以下就重型柱吊装中的几个技术问题作一研讨。一、无垫板和有垫板安装重型柱子安装,目前大都采取在杯底抹找平层的方法(即无垫板安装)如图1a、b,即在柱基施工时,在杯底预留5厘米厚空隙,安装前根据柱子底面的实际长短差和平整情况,逐个确定杯底、柱子
In the construction of large-scale industrial plants, the lifting of heavy-duty columns often occupies a very important position, not only because of its large height and weight (up to 25-60 tons), but also because of the heavy lifting equipment, and the complicated and difficult lifting technology. The requirements are high. Whether it is hoisted smoothly or not, often affects the quality and progress of the entire hoisting project. The following is a discussion of several technical issues in the lifting of heavy-duty columns. First, the installation of heavy-duty pillars without backing plates and underlays is mostly adopted at the bottom of the cup leveling method (that is, without the pad installed) as shown in Figure 1a, b, that is, in the construction of the column base, reserved at the bottom of the cup 5 cm thick gap, according to the actual length and length of the bottom of the column before installation, determine the cup bottom and column one by one.
