Concrete precast pile mechanical connecting piece
The invention discloses a concrete precast pile mechanical connecting piece which comprises a pile end plate and a pile hoop embedded at the pile end of a precast pile in a sleeving mode, two anti-pulling convex ribs are annularly formed on the pile hoop, a radial convex edge is inwards formed at the upper end of the pile hoop in the radial direction, and the top face of the radial convex edge and the pile end face of the precast pile are located on the same horizontal plane. The pile end plate and the pile hoop are welded and connected into a whole, and an assembly welding seam is formed between the bottom face of the pile end plate and the inner side face of the radial convex edge of the pile hoop. An L-shaped notch is formed in the periphery of the bottom surface of the pile end plate, and the L-shaped notch is matched with the radial convex edge of the pile hoop to form a connecting clamping groove; a connecting clamp used for connecting the pile end plates of the two piles into a whole in a clamped mode is installed in the connecting clamping groove in a clamped mode, and the connecting clamp is formed by combining at least two unit connecting clamps. The method is high in connecting speed, safe and reliable, the tensile strength of the two piles after butt joint can be guaranteed, and the problems that the traditional pile foundation connecting quality cannot be guaranteed, and the drawing resistance bearing capacity is insufficient are solved.
本发明公开了混凝土预制桩机械连接件，包括桩端板和套装预埋在预制桩桩端的桩套箍，桩套箍上环向成型有两道抗拔凸筋，该桩套箍的上端径向向内形成有径向凸边，径向凸边的顶面与预制桩的桩端面处于同一水平面上；桩端板与桩套箍焊接相连成一体，桩端板的底面与桩套箍径向凸边的内侧面间形成有组装焊缝；桩端板的底面周边成型有L形槽口，L形槽口与桩套箍的径向凸边相配合形成有连接卡槽；连接卡槽中卡装有用于将两桩的桩端板卡接相连成一体的连接卡箍，连接卡箍至少由两个单元连接卡箍组合构成。本发明连接速度快，并且安全可靠，能保证两桩对接后的抗拉强度，解决了传统桩基连接质量不能保证、抗拉拔力承载力不足的问题。
