Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them.

[0029] like figure 1 As shown, a concrete prefabricated pile with mixed reinforcement of glass fiber bars and steel bars includes a pile body 10 with anchor plates 11 arranged at both ends, and a steel skeleton cage 20 is arranged inside the pile body 10, and the steel skeleton cage 20 includes prestressed steel bars 21, glass fiber bars 22 and spiral stirrups 23. The prestressed steel bars 21 and glass fiber bars 22 are arranged parallel to each other, and both are arranged in the same cylinder with the center line of the pile body as the axis. On the surface; the length of the prestressed steel bar 21 is greater than the length of the glass fiber bar 22, and the two e...

Abstract

The invention belongs to the technical field of concrete precast piles, and particularly relates to a concrete precast pile with mixed reinforcement glass fiber-reinforced polymers and steel bars. The concrete precast pile comprises a pile body with the two ends provided with anchor plates, wherein a reinforcement cage is arranged in the pile body and comprises prestressed reinforcements, the glass fiber-reinforced polymers and spiral stirrups, and the prestressed reinforcements and the glass fiber-reinforced polymers are distributed on the same cylindrical face with the central line of the pile body as the axis; the two ends of each prestressed reinforcement are fixedly connected with the anchor plates arranged at the two ends of the pile body respectively, the prestressed reinforcements and the spiral stirrups are welded together, and the glass fiber-reinforced polymers and the spiral stirrups are bound together. The concrete precast pile has the advantages of being high in bending resistance, good in durability, good in anti-seismic property and the like, and can be well applied to areas where the requirement for horizontal loads is high; meanwhile, the concrete precast pile is low in manufacturing cost, saves steel, and is convenient to construct and transport.

Description

technical field [0001] The invention belongs to the technical field of concrete prefabricated piles, in particular to a concrete prefabricated pile with mixed reinforcement of glass fiber bars and steel bars. Background technique [0002] Concrete prefabricated pile refers to a slender concrete prefabricated component made by prestressing and centrifugal forming method. In order to improve the performance of prefabricated piles, a steel skeleton composed of steel main reinforcement and spiral stirrup can be set in this type of pile. Concrete prefabricated piles have the advantages of industrial scale production, easy quality assurance, high single pile bearing capacity, strong adaptability to project site conditions, fast construction speed, and no pollution on site. But concrete prefabricated piles have problems of poor bending resistance of the pile body and durability of reinforced concrete structures. These defects seriously limit the large-scale application of prestres...
