Abstract

The present invention relates to the technical field related to the pile connection structure of prestressed pipe piles, in particular to an extruded and expanded branch disk pile connection structure for prestressed pipe piles, aiming to solve the poor compression and pullout bearing capacity of existing prestressed pipe piles technical issues. It includes an upper end plate and a lower end plate. A rectangular hole is opened in the center of the upper end plate. A cylinder is fixedly connected between the upper end plate and the lower end plate. There are multiple casings evenly distributed in the cylinder, and there are multiple sleeves evenly distributed in the cylinder along its circumference. Each link assembly is composed of an upper link and a lower link that are symmetrically distributed up and down. The upper link and the lower link are arranged obliquely. The upper end of the upper link is hinged on the lower surface of the upper end plate, and the lower link The lower end of the connecting rod is hinged on the upper surface of the lower end plate, and the lower end of the upper connecting rod and the upper end of the lower connecting rod are jointly hinged on the inner wall of the cylinder; a pressure-bearing column is also arranged, the cross-section of the pressure-bearing column is rectangular, and the pressure-bearing column The height of the column is equal to the distance between the upper and lower end plates.

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...
