Pile cap of prefabricated square concrete pile
A pile cap of a prefabricated square concrete pile comprises four skirt plates, a top plate and a plurality of connecting pieces. A square body is formed by the four skirt plates in an enclosed mode. The top plate is welded to the top end of the square body. Each connecting piece comprises a double-thread screw and a pin bush. Each pin bush comprises an open box and two semi-bush mechanisms. Each semi-bush mechanism comprises a semi-bush body and a pressure spring. The front face of each semi-bush body is concave inwards to form a concave part. A sleeving space is formed between the concave parts of every two semi-bush bodies. The back face of each open box is fixed to a screw hole of the top plate. One end of each double-thread screw is pressed in the corresponding sleeving space, and the other end of each double-thread screw is rotationally connected with the interior of a screw hole of a top plate of another pile cap. One end of each pressure spring is fixed to the inner wall of the corresponding open box, and the other end of each pressure spring is fixedly connected to the back face of the corresponding semi-bush body. According to the pile cap of the prefabricated square concrete pile, connection is easy, convenient, fast and firm, the bearing capacity is high, the quality is stable, operation is simple, and the construction quality and speed of pile connection can be increased effectively.
