Pile pulling anchorage device
The invention relates to a pile pulling anchorage device for providing pile pulling force by using a main reinforcement of a pile. The pile pulling anchorage device comprises an anchor seat, the anchor seat is formed by welding an outer anchor ring, an inner anchor ring, a center cylinder and a radial plate, and the diameter of the center line of an annular groove formed between the outer anchor ring and the inner anchor ring is the same as the diameter of a pile pulling main reinforcement distribution circle. The inner side face of the outer anchor ring is a conical face. And the outer side surface of the inner anchor ring is a conical surface. Threads are arranged on the inner side of the center cylinder. And the radial plate is a connecting plate of the inner anchor ring, the outer anchor ring and the central cylinder. The pile pulling anchorage device further comprises an inner clamping piece and an outer clamping piece which are used in pairs. The pile pulling anchorage device further comprises a pull rod which is in threaded connection with the central cylinder. According to the pile pulling anchorage device, a main rib of a pulled pile can be uniformly stressed, and the pile pulling anchorage device is convenient to assemble and disassemble and can be repeatedly used.
本发明涉及一种利用桩的主筋提供拔桩力的拔桩锚具。本拔桩锚具包括锚座，所述的锚座由外锚环、内锚环、中心筒和辐板焊接组成，其外锚环与内锚环之间形成的环形槽中心线直径与所拔桩主筋分布园直径相同。所述的外锚环，其内侧面为圆锥面。所述的内锚环，其外侧面为圆锥面。所述的中心筒，其内侧设置螺纹。所述的辐板为内锚环、外锚环及中心筒三者的连接板。本拔桩锚具还包括成对使用的内夹片和外夹片。本拔桩锚具还包括与所述中心筒采用螺纹连接的拉杆。本拔桩锚具不仅能是所拔桩主筋受力均匀，而且装拆方便，可反复使用。
