Prestressed concrete rectangular pile with arc-shaped corners
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.
本发明公开一种角部弧形的预应力混凝土矩形桩，包括混凝土桩身和位于所述混凝土桩身内部的钢筋笼，矩形桩的所述混凝土桩身的四个角为圆角，所述钢筋笼包括纵筋和螺旋箍筋，所述纵筋绑扎在所述螺旋箍筋上，所述螺旋箍筋上与所述混凝土桩身的圆角对应的角部为弧形角部。矩形桩包括方桩和长方形桩，矩形桩横截面角部做圆角，螺旋箍筋角部做成弧形；相比于角部为直角的混凝土预制桩，角部圆角时混凝土密实度更高，在运输和吊装过程中角部不易磕碰脱落；箍筋角部做成弧形，在受压情况下，横向钢筋对混凝土的约束性能更好，受力更加合理便于机械制绕制钢筋骨架，提高劳动效率。
