Uplift pile cap
The invention relates to an uplift pile cap, which comprises a cylinder body and a piston, wherein a cavity is arranged in the cylinder body; the piston comprises an upper end plate, a lower end plateand a stroke rod; the upper end plate is arranged in the cylinder body and can move along the axial direction of the cylinder body; and the lower end plate is arranged out of the cylinder body and isconnected with the upper end plate through the stroke rod. According to the uplift pile cap provided by the invention, two stress states that a pile body is pulled and pressed can be distinguished, and when the pile body is pressed, the pile body can stop working, does not participate in structure stress and can effectively perform a function only when the pile body resists floating and is pulled. According to the design, a pile body arrangement amount is effectively reduced, engineering construction cost is greatly lowered, and the uplift pile cap has an obvious economic benefit.
本发明涉及一种抗拔桩帽，其包括缸体与活塞，缸体的内部设有腔室，活塞包括上端板、下端板和行程杆，上端板设于缸体内并可沿缸体的轴向运动，下端板设于缸体外并与上端板通过行程杆相连接。本发明提供的抗拔桩帽将桩体受拉和受压的两种受力状态区分开来，使得桩体在受压时能够退出工作，不参与结构受力，而仅在抗浮受拉时能够有效发挥作用。该设计有效减少了桩体的设置数量，大幅度降低了工程造价，具有显著的经济效益。
