Embodiment 1

[0038] Such as Figure 1-2 As shown, a prestressed concrete square pile is provided in this embodiment, which includes a concrete pile body 1 and a reinforcement cage located inside the concrete pile body 1. The reinforcement cage mainly includes prestressed reinforcement bars 21, non-prestressed reinforcement bars 22, spiral hoops Rib 23, the outstanding feature is that the corner of the pile body is rounded 3, the steel cage is made into an arc at the corner, and the longitudinal reinforcement adopts prestressed reinforcement 21 and non-prestressed reinforcement 22 at the same time, prestressed reinforcement 21 and non-prestressed reinforcement 22 All adopt two-way symmetrical arrangement.

[0039] Such as figure 1 Among them, the prestressed steel bars 21 are arranged symmetrically at the corners of the square pile 1, and there are four prestressed steel bars 21. The advantage of placing the prestressed steel bars 21 at the corners is that the corners are prestressed, the ...

Embodiment 2

[0046] Such as Figure 3-4 As shown, this embodiment provides a prestressed concrete rectangular pile with curved corners. On the basis of Embodiment 1, the rectangular pile of this embodiment also has the following characteristics: the rectangular pile in this embodiment is a rectangular pile. Such as image 3 Among them, the prestressed steel bars 21 are symmetrically arranged at the corners of the rectangular pile 1, and there are 6 prestressed steel bars 21. The advantage of placing one prestressed steel bar 21 at the corner and the middle part of the long side is that the prestressed stress of the section is uniform, and the middle part of the section is in the prestressed area. The non-prestressed reinforcement bars 22 are arranged symmetrically on both sides of the stress reinforcement bars 21, and there are 6 non-prestressed reinforcement bars 22. The pile body is made of corrosion-resistant concrete.

[0047] Such as Figure 4 Among them, compared with the rectangula...

Abstract

The invention discloses a prestressed concrete rectangular pile with arc-shaped corners. The prestressed concrete rectangular pile comprises a concrete pile body and a reinforcement cage located in the concrete pile body. The four corners of the concrete pile body of the rectangular pile are round corners. The reinforcement cage comprises longitudinal bars and spiral stirrups. The longitudinal bars are bound to the spiral stirrups. The corners, corresponding to the round corners of the concrete pile body, of the spiral stirrups are arc-shaped corners. The rectangular pile comprises a square pile body and a rectangular pile body. The corners of the cross section of the rectangular pile body are round corners. The corners of the spiral stirrups are made to be arc-shaped. Compared with a concrete prefabricated pile with right-angle corners, the prestressed concrete rectangular pile with the arc-shaped corners has the advantages that the concrete compactness is higher when the corners areround corners, and the corners are not prone to being knocked off in the transporting and hoisting process; and the corners of the stirrups are made to be arc-shaped, under the pressed condition, theconstraint performance of transverse steel bars on concrete is better, stress is more reasonable, a steel bar framework can be mechanically wound conveniently, and the labor efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of pipe piles, in particular to a prestressed concrete rectangular pile with arc-shaped corners. Background technique [0002] The pipe piles in the prior art generally have unreasonable structure and reinforcement problems, resulting in poor compression, bending, and shear performance of the pipe piles, and poor ductility of the pile body. Contents of the invention [0003] The purpose of the present invention is to provide a prestressed concrete rectangular pile with arc-shaped corners to solve the problems in the above-mentioned prior art. The structural reinforcement is reasonable and the mechanical performance is excellent; Has a certain degree of ductility. [0004] In order to achieve the above object, the present invention provides the following scheme: the present invention provides a prestressed concrete rectangular pile with arc-shaped corners, comprising a concrete pile body and a steel cage p...
