- 摘要:
- 塔器设备和钢结构安装时,地脚螺栓的预紧力必须控制在一定范围内,但设备安装、试车后螺栓应力的初松弛,使地脚螺栓的预紧力不可能保持不变,因而将给设备运行带来隐患。为此在全面考虑预紧力影响因素的基础上,归纳提出塔器设备地脚螺栓预紧力设定和控制的定量依据,并进行了分析探讨。
Prestress of anchor bolt must be controlled in a certain range when tower equipment andsteel structures are installed. Prestress of anchor bolt can be changed because of the initial looseof bolt after mounting the equipment so that a hidden perils would be existed in equipment opera-tion. On the basis of prestress affecting factors in overall considerations,the setting and control-ling of the prestress of anchor bolt for tower equipment are enumerated,and theoretical analyzingand approaching are also made.1997,2(2): 14-21 收稿日期:1997-9-2参考文献:
