End-plate-free concrete precast pile expansion type connecting device and precast pile
The invention discloses an end-plate-free concrete precast pile expansion type connecting device and a precast pile. The expansion type connecting device comprises an outer sleeve, a fixing hoop and a connecting bolt. The fixing hoop is fixedly arranged in the outer sleeve, and a plurality of first inverted teeth are arranged on the inner wall of the fixing hoop; the connecting bolt is used for connecting two adjacent end-plate-free concrete precast piles, the connecting bolt is provided with a plurality of second inverted teeth, and the first inverted teeth and the second inverted teeth are meshed and locked when the pile bodies are connected. The expansion type connecting device is convenient to connect, and the connecting reliability of the end-plate-free concrete precast pile can be improved.
本发明公开了一种无端板混凝土预制桩膨胀式连接装置及预制桩，膨胀式连接装置包括：外套筒、固定箍和连接螺栓；固定箍固定设置于外套筒内，其内壁设置有多个第一倒齿；连接螺栓用于连接相邻的两个无端板混凝土预制桩，连接螺栓设置多个第二倒齿，桩体连接时第一倒齿与所述第二倒齿啮合且锁止。本发明膨胀式连接装置连接方便，且可提高无端板混凝土预制桩的连接可靠性。
