一种预制型隧道锁脚锚杆与钢架连接构件
摘要：
本实用新型公开一种预制型隧道锁脚锚杆与钢架连接构件，属于隧道工程技术领域。本实用新型由锁脚锚杆、支护钢架、定位环片、左幅螺栓套筒、右幅螺栓套筒、螺栓扣件组成。在准备阶段，首先针对锁脚锚杆端头（与钢架连接一侧）进行螺纹加工预处理；其次，根据锁脚锚杆设计位置和施工角度，将定位环片焊接于支护钢架相应位置处。在施工阶段，锁脚锚杆通过支护钢架前后定位环片精准定位施工，之后利用预制左幅螺栓套筒、右幅螺栓套筒、螺栓扣件将支护钢架两侧锁脚锚杆锚固连接成为一个整体。采用本实用新型结构，可实现锁脚锚杆精准施工及其与支护钢架的稳固连接，增强隧道初支结构整体稳定性，有效解决隧道工程施工一大难题。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The utility model discloses a prefabricated type tunnel feet -lock bolt and steelframe connecting elements belongs to tunnel engineering technical field. The utility model discloses by feet -lock bolt, strut steelframe, holding ring piece, left side width of cloth bolt collar, right side width of cloth bolt collar, the bolt fastener is constituteed. In the preparatory stage, at first carry out thethread processing preliminary treatment to feet -lock bolt end (being connected one side with the steelframe), secondly, according to feet -lock bolt design position and construction angle, with theholding ring chip bonding in strutting steelframe relevant position department. At construction stage, feet -lock bolt is under construction through the accurate location of holding ring piece aroundstrutting the steelframe, later utilizes prefabricated left side width of cloth bolt collar, right width of cloth bolt collar, bolt fastener will strut the feet -lock bolt anchor of steelframe both sides and connect into to a whole. Adopt the utility model discloses the structure, can realize the accurate construction of feet -lock bolt and with strut the firm of steelframe and be connected, the reinforcing tunnel just props up structural overall stability, effectively solves a construction of tunnel engineering big difficult problem.
