Back pulling tray type anchor rod
The invention discloses a back pulling tray type anchor rod which comprises a bottom tray and an anchor rod body. A fixed support is arranged in the middle of the upper side of the bottom tray. The anchor rod body is connected with the bottom tray through the fixed support. Shaft bases are arrayed on the edge of the fixed support in a whole cycle. The shaft bases are rotationally connected with wing panels through pins. Ribbed plates are arranged in the middles of the lower sides of the wing panels. Telescopic springs are arranged between the bottoms of the ends, away from the shaft bases, ofthe ribbed plates and the bottom edges of the bottom tray. Torsional springs sleeve the pins. The design pile length of the anchor rod can be reduced, the ultimate pullout capacity of an anchor rod pile is greatly improved, construction workload and construction cost are reduced, and the back pulling tray type anchor rod has quite high practicability.
本发明公开了一种背拉式托盘式锚杆，包括底部托盘、锚杆，所述底部托盘的上方中部设有固定支架，所述锚杆通过固定支架与底部托盘连接；所述固定支架的边缘整周阵列设有轴座，所述轴座通过柱销转动连接有翼板，所述翼板下方中部设有加筋板，所述加筋板的远离轴座端的底部与底部托盘的底部边缘之间设有伸缩弹簧，所述柱销上套有扭簧。本发明可以减小锚杆设计桩长，大幅度提高锚杆桩极限抗拔力，减少施工工作量及施工成本，具有很好的实用性。
