Connecting structure of front support grouting steel pipe and reinforcing steel bar sleeves
The invention provides a connecting structure of a front support grouting steel pipe and reinforcing steel bar sleeves. The connecting structure comprises the front support grouting steel pipe, sleeves and reinforcing steel bars, and is characterized in that the top end of the front support grouting steel pipe is arranged in a top beam of a foundation pit according to the design; each sleeve is provided with internal threads; the reinforcing steel bars are L-shaped; threads matched with the threads in the sleeves are arranged at the long ends of the L-shaped reinforcing steel bars; the long ends of the L-shaped reinforcing steel bars are screwed into the sleeves to form the reinforcing steel bar sleeves; the sleeve ends of the reinforcing steel bar sleeves are fixedly welded to the circumference of the top end of the front supporting grouting steel pipe in the radial direction; the corresponding reinforcing steel bar sleeves are symmetrically arranged on the front supporting grouting steel pipe in a cross mode; and the length of the reinforcing steel bar sleeves is 100 mm. The connecting structure of the front support grouting steel pipe and the reinforcing steel bar sleeves has the advantages that the device structure is simple, manufacturing is convenient, sleeve threading increases the welding contact face with the grouting steel pipe, the bond stress of concrete is improved, the reinforcing steel bars and the sleeves are connected and combined, the stress performance is good, overall stress stability is guaranteed, construction is convenient, stress is reliable, and cost is saved.
一种前撑注浆钢管与钢筋套筒的连接结构，包括前撑注浆钢管、套筒、钢筋，其特征在于：所述前撑注浆钢管根据设计前撑注浆钢管顶端置于基坑的冠梁内；所述套筒设有内螺纹；所述钢筋呈L形，L形钢筋的长端设有与套筒内螺纹配合的螺纹，且旋进套筒内组合成钢筋套筒，其中：将若干钢筋套筒的套筒端呈径向固焊于前撑注浆钢管顶端圆周上，相应的钢筋套筒为十字对称设置在前撑注浆钢管上，钢筋套筒的长度为100mm。本发明的前撑注浆钢管与钢筋套筒的连接结构具有装置结构简单、制作方便，套筒套丝增加与注浆钢管焊接接触面，提高混凝土的握裹力，钢筋与套筒连接组合受力性能好保证整体受力稳定，方便施工、受力可靠和节约成本的优点。
