钢结构塔桅通常采用预埋地脚锚栓与基础进行连接,地脚锚栓常用材质为45#钢或40Cr,这些钢材焊接性能很差,当地脚锚栓露出基础部分因外力破坏时,原有地脚锚栓通常情况下无法再利用,只能重新更换地脚锚栓并浇筑基础,成本高,周期长,针对这一问题,本文介绍了一种接长套筒螺杆技术,此技术连接可靠、施工方便、成本低,在实际工程中已经应用,取得了良好的效果,可以推广应用。
The steel mast tower mast is usually used to connect the foundation embedded anchor bolt connection, anchor anchor commonly used material is 45 # steel or 40Cr, these steel welding performance is poor, the local anchor bolt exposed part of the foundation due to external damage, the original There are often no way to use the anchor bolt, you can only re-replace the anchor bolts and pouring the foundation, high cost, long cycle, in response to this problem, this article describes a long sleeve screw technology, this technology connection Reliable, convenient construction, low cost, has been applied in practical projects, and achieved good results, which can be widely applied.
