Steel strand prestressed pile connector
A steel strand prestressed pile connector comprises an upper pile and a lower pile, the upper pile comprises upper pile concrete, an upper pile prestressed steel strand and a corrugated pipe, the prestressed steel strand and the corrugated pipe are embedded in the upper pile concrete, an anchoring hole is formed in the side face of the upper pile concrete, an anchor plate is embedded in the anchoring hole, a tensioning anchorage device is arranged on the outer side of the anchor plate, and the tensioning anchorage device is connected with the prestressed steel strand. The upper pile comprises an upper pile concrete and an upper pile prestressed steel strand, the lower pile comprises lower pile concrete and a lower pile prestressed steel strand, the lower pile prestressed steel strand extends out of the upper end face of the lower pile concrete by a certain height, and the lower pile prestressed steel strand extends out of the upper end face of the lower pile concrete by a certain height. The lower pile prestressed steel strand extends into the corrugated pipe of the upper pile and is fixedly connected with the tensioning anchorage device, and the corrugated pipe is filled with grouting materials. The connector is high in tensile strength, the piles are produced through a long-line method, the prefabrication cost is low, the upper pile and the lower pile are connected through anchorage and grouting bonding, connection is reliable, and the construction efficiency is high.
