Embodiment Construction

[0017] Such as figure 1 As shown, the regular quadrilateral chamfered pile of the 400×400mm model of the present invention includes a concrete pile body 1 and a reinforcement cage 2 positioned inside the concrete pile body 1, and the reinforcement cage 2 mainly includes spiral stirrups 21, prestressed tendons 22, An outstanding feature of the anchor bars 23 and erecting stirrups 25 is that the cross-section of the reinforcement cage 2 is a polygon with cut corners 24, and the cut corners 24 are arc-shaped. The advantage of cutting corners in an arc shape is that the thickness of the concrete on both sides of the prestressed tendons on the cutting corners is basically the same, and the stress at the connection between the long side and the short side can also be reduced. Specifically, the erecting stirrups 21 are polygonal with cut corners 24, and the cut corners 24 are arc-shaped spiral stirrups 21 located outside the erecting stirrups 21, thereby forming the basic structure o...

Abstract

The invention discloses a pre-tensioning method prestress concrete cut-corner pile, which comprises a concrete pile body and a reinforcing steel bar cage, wherein the concrete pile body is provided with a plurality of cut corners, the reinforcing steel bar cage is positioned inside the concrete pile body and comprises a spiral hoop bar, a pre-stress bar and an anchoring bar, the cross section of the reinforcing steel bar cage is in a polygon shape with cut corners, and in addition, the cut corners are in arc shapes. The cut-corner pile provided by the invention has the advantages that the structure is reasonable, and the mechanical property is excellent.

Description

[0001] This application is a divisional application with an application date of February 1, 2013, an application number of 201310039121.2, and an invention title of "Pretensioned Prestressed Concrete Corner Pile". technical field [0002] The invention relates to pipe piles, in particular to a pretensioned prestressed concrete angle-cutting pile. Background technique [0003] The pipe piles in the prior art generally have the problems of unreasonable structure and reinforcement, which lead to uneven stress, poor tensile, compressive and bending properties of the pipe piles. Contents of the invention [0004] Purpose of the invention: the purpose of the invention is to provide a pre-tensioned prestressed concrete angle-cutting pile with excellent mechanical properties. [0005] Technical solution: The pre-tensioned prestressed concrete upper cut corner pile of the present invention includes a concrete upper pile body with multiple cut corners and a reinforcement cage locate...
