Description

Technical Field

[0001] The invention relates to a pre-tensioned prestressed concrete double-sided imitation wood pile, belonging to the technical field of engineering construction. Background Art

[0002] Precast piles are widely used in the foundation of industrial and civil buildings, and can be used as pile foundations for water-related buildings such as docks, breakwaters, ship locks, high-rise buildings, and underground buildings. Such precast piles can effectively improve the load capacity and earthquake resistance of buildings.

[0003] At present, a large number of projects have adopted precast piles as precast components for slope or foundation pit support, including centrifugal forming and cast forming. The centrifugal precast piles generally have a regular shape. After forming a pile row support structure, most pile types have a relatively flat facade and a monotonous shape. Cast-formed piles are mostly special-shaped components with undulating facades and high aesthetics, but their production efficiency is low and their manufacturing cost is high.

[0004] Therefore, it is necessary to invent a prestressed concrete double-sided imitation wood pile to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a pre-tensioned prestressed concrete double-sided imitation wood pile with high load capacity, good earthquake resistance and beautiful appearance.

[0006] In order to achieve the above object, the present invention provides the following technical solutions: A pre-tensioned prestressed concrete double-sided imitation wood pile, comprising: At least 6 prestressed steel bars: the prestressed steel bars are arranged equidistantly along the spiral stirrups; Spiral stirrups: the spiral stirrups are sleeved around the outer circumference of the prestressed steel bars; Pile hoop; the pile hoop is arranged on the outer periphery of the spiral stirrup, and the pile hoop is arranged to form a circular pile main body cavity; End plates: The end plates are arranged at both ends of the prestressed steel bars.

[0007] Furthermore, the prestressed steel bar is a steel bar for prestressed concrete with a diameter of not less than 7.1 mm.

[0008] Furthermore, the inner hole of the end plate is a circular hole.

[0009] Furthermore, symmetrically arranged wing edges are provided on both sides of the end plate, and both wing edges are provided with tongues and grooves; the tongue and groove on one side is an inwardly concave arc, and the tongue and groove on the other side is an outwardly convex arc.

[0010] Furthermore, when multiple sections of prestressed concrete double-sided imitation wood piles are connected, welding connection or mechanical connection can be used.

[0011] The beneficial effects of the present invention are: 1. The prefabricated piles of the present invention and the end plates matching the prefabricated piles have reasonable structures, beautiful shapes and large retaining widths; 2. Use high-strength steel bars instead of ordinary steel bars to reduce the amount of steel used while meeting the same force requirements, further saving resources.
