Embodiment Construction

[0015] Such as Figure 1a and Figure 1b As shown, the regular quadrilateral solid square pile of 400 * 400mm model of the present invention comprises concrete pile body 1 and is positioned at the reinforcement cage 2 inside concrete pile body 1, and described reinforcement cage 2 mainly comprises spiral stirrup 21, prestressed tendon 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 the cut corner being arc-shaped is that the concrete thickness on the inside and outside of the prestressed tendon on the cut corner side 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 25 are polygons with cut corners 24, and the cut corners 24 are arc-shaped spiral stirrups 21 located outside the erecting stirrups 21, thereby ...

Abstract

The invention discloses a pretensioned prestressing solid concrete pile. The solid concrete pile comprises a concrete pile body with a plurality of corner cuts and a reinforcing cage positioned in the concrete pile body, wherein the reinforcing cage comprises spiral stirrups, prestressed reinforcements and anchor bars; and the cross-section of the reinforcing cage takes the shape of a polygon with arc-shaped corner cuts. The solid concrete pile is reasonable in structure and arrangement design of the reinforcements, and excellent in physical property.

Description

technical field [0001] The invention relates to a solid square pile, in particular to a pretensioned prestressed concrete solid square pile. Background technique [0002] The solid square 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 solid square piles. Contents of the invention [0003] Purpose of the invention: the purpose of the invention is to provide a pretensioned prestressed concrete solid square pile with excellent mechanical properties. [0004] Technical solution: The pretensioned prestressed concrete solid square pile of the present invention includes a concrete pile body with multiple cut corners and a reinforcement cage located inside the concrete pile body, and the reinforcement cage includes spiral stirrups, prestressed tendons and the anchor bar, the cross-section of the reinforcement cage is a polygon with cut corners, and...
