Abstract

The invention discloses a mechanical splice of a pre-stressed concrete tubular pile, comprising a connecting pin and at least two fixture blocks, wherein the two fixture blocks are arranged oppositely; first latches are arranged on opposite surfaces of the fixture blocks; elastic components are arranged on back surfaces of the fixture blocks; an external thread is arranged at a first end of the connecting pin and second latches are arranged at a second end of the connecting pin; the second end of the connecting pin is inserted between the fixture blocks; the first latches and the second latches are blocked and buckled mutually; and the first latches and the second latches are both of screw thread type. The invention also provides a pre-stressed concrete tubular pile with the mechanical splice. The mechanism splice and the pre-stress concrete tubular pile disclosed by the invention have the advantages of simpleness in machining, high pullout resistance, high bearing capacity and corrosion proofing capability.

Description

technical field [0001] The invention relates to a prestressed concrete pipe pile mechanical joint for connecting two-section pipe piles and a prestressed concrete pipe pile. Background technique [0002] In building construction, it is often necessary to bury concrete pipe piles underground. After the usual concrete pipe piles are prefabricated, they are connected to the upper and lower sections of pipe piles by welding on site. This structure slows down the construction speed and costs High, and the connection quality is difficult to guarantee. In order to solve this problem, one of the applicants of the present invention applied for a quick connector for prestressed concrete pipe piles (publication number CN2495685) on August 1, 2001, which includes a fixed connection with the connecting ends of the upper and lower piles respectively. There are two end plates and connecting pins. There is a threaded hole in the end plate of the pile. One end of the connecting pin is threa...
