Reinforcement skeleton cage for concrete prefabricated pile

Abstract

The invention belongs to the technical field of concrete prefabricated piles, and in particular, relates to a reinforcement skeleton cage for a concrete prefabricated pile. The reinforcement skeleton cage comprises a stirrup, prestressed reinforcements arranged in the length direction of the prefabricated pile, and glass fiber ribs; and the prestressed reinforcements are welded in the peripheral direction of the stirrup at intervals to form a cage body. The reinforcement skeleton cage is characterized in that a positioning disc is clamped in the cage body; and a positioning hole for penetrating through the glass fiber rib is formed in the positioning disc. The positioning disc is clamped in the cage body; the glass fiber rib is positioned and mounted in the cage body after penetrating through the positioning hole; and the mounting structure keeps stable mounting position of the glass fiber rib in the manufacturing or use process of the concrete prefabricated pile, so that the reinforcement skeleton cage is more firm in structure, and largely guarantees the tensile strength and the impact resistance of the concrete prefabricated pile.

Description

technical field [0001] The invention belongs to the technical field of concrete prefabricated piles, in particular to a steel skeleton cage used in concrete prefabricated piles. 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, such piles are provided with steel cages. The traditional steel cages are composed of main reinforcement and stirrups. The tendons are used to alternately arrange prestressed steel bars and glass fiber bars on the same cylindrical surface with the center line of the prefabricated pile as the axis, wherein the prestressed steel bars and stirrups are welded, and the glass fiber bars and stirrups are tied together. The disadvantages of this connection method: during the formation and use of concrete prefabricated piles, the connection method of binding glass fiber bars and stirrups ...

Problems solved by technology

In order to improve the performance of prefabricated piles, such piles are provided with steel cages. The traditional steel cages are composed of main reinforcement and stirrups. The tendons are used to alternately arrange prestressed steel bars and glass fiber bars at intervals on the same cylindrical surface with the center line of the prefabricated pile as the axis, wherein the prestressed steel bars and stirrups are welded, and the glass fiber bars and stirrups are bound together The disadvantages of this connection method: during the formation and use of concrete prefabricated piles, the connection method of binding glass fiber bars and stirrups is extremely unreliable and easy to loosen, causing glass fiber bars to shift, thus affecting the entire concrete Mechanical properties of prefabricated piles, such as tensile properties, impact resistance
