The invention relates to the related technical field of pile splicing structures of prestressed pipe piles, in particular to a splicing structure for piles with expanded branches and plates for a prestressed pipe pile, and aims at solving the technical problem that an existing prestressed pipe pile is poor in compressive and uplift bearing capacity. The structure comprises an upper end plate and alower end plate, a rectangular hole is formed in the center of the upper end plate, a cylinder is fixedly connected between the upper end plate and the lower end plate, a plurality of sleeves are evenly distributed in the cylinder, a plurality of connecting rod assemblies are evenly distributed in the cylinder in the circumferential direction of the cylinder, and each connecting rod assembly is composed of an upper connecting rod and a lower connecting rod which are symmetrically distributed up and down, the upper connecting rod and the lower connecting rod are arranged in an inclined mode, the upper end of the upper connecting rod is hinged to the lower surface of the upper end plate, the lower end of the lower connecting rod is hinged to the upper surface of the lower end plate, and thelower end of the upper connecting rod and the upper end of the lower connecting rod are together hinged to the inner wall of the cylinder. A pressure-bearing column is further arranged, the cross section of the pressure-bearing column is rectangular, and the height of the pressure-bearing column is equal to the distance between the upper end plate and the lower end plate.
Description
technical field [0001] The invention relates to the technical field related to the pile connection structure of prestressed pipe piles, in particular to an extruded and expanded branch plate pile connection structure for prestressed pipe piles. Background technique [0002] With the rapid development and continuous improvement of engineering technology, the efficient use of underground space has been valued by the industry, and pile foundations have been born to meet the requirements of super high-rise buildings and other projects for the bearing capacity of foundations. Concrete piles are mainly divided into two categories: prestressed concrete pipe piles (ie prestressed pipe piles) and concrete pouring piles. Restricted by the current technical level and economic factors, prestressed pipe piles have become the most preferred pile type in housing construction and other projects. They have the advantages of short construction period, relatively economical project cost, large...
