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,

Embodiment Construction

[0021] Below in conjunction with embodiment technical solution of the present invention is made more specific description:

[0022] Such as figure 1 As shown, the present invention includes stirrups 11, prestressed steel bars 12 and glass fiber bars 13 arranged along the length direction of the prefabricated pile 10, and the prestressed steel bars 12 are welded at intervals in the circumferential direction of the stirrups 11 to form a cage A positioning plate 14 is clamped inside the cage, and a positioning hole 141 is provided on the positioning plate 14 for the glass fiber ribs 13 to pass through. The positioning plate 14 of the present invention is stuck in the cage, and secondly, the glass fiber reinforcement 13 is positioned and installed in the cage after passing through the positioning hole 141. The installation position of the fiber reinforcement 13 remains stable and reliable, that is, the steel skeleton cage structure of the present invention is more reliable, which...

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 ...
