在设备安装中,大都采用现浇或预埋的固定地脚螺栓。这种固定地脚螺栓对于经常拆卸或来回变更工作地点的小型工装设备极不便利。一是拆卸后地面不整洁,二是螺栓易损坏不便修复。我们在安装来回变更工作地点的工装时,根据工作实践经验,设计出一种新型活动地脚螺栓,如图所示。其结构安装拆卸方便,并能保持拆卸后地面平整,螺栓损坏后 In equipment installation, most of the use of cast-in-place or embedded anchor bolts. This fixed anchor bolt can be extremely inconvenient for small fixture equipment that often disassemble or change workplaces frequently. First, after disassembling the ground is not clean, and second, easy to damage the bolt repair inconvenience. When installing the tooling for changing locations back and forth, we designed a new type of activity anchor bolt based on practical work experience, as shown in the figure. The structure is easy to install and disassemble, and can keep the floor surface after disassembly, after the bolt is damaged
