Problems solved by technology

Traditional H-shaped piles are often unusable due to insufficient bending and shear resistance, especially in high-rise buildings
In addition, in foundation pit enclosure, slope support and other projects, traditional H-shaped piles cannot be applied on a large scale due to insufficient bending and shear performance.

Embodiment Construction

[0048] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0049] Such as Figure 1-10 As shown, it is a preferred embodiment of the present invention. In this embodiment, both ends of the H-shaped pile are provided with end plates 2 as an example.

[0050] A method for manufacturing an H-shaped pile with steel strands, wherein the H-shaped pile includes a concrete pile body 1 with an H-shaped cross section, and a reinforcement cage located in the concrete pile body 1; the reinforcement cage includes axially arranged steel strands The wire 3, the stirrup 4 that is sheathed in series on the steel strand, and the end plates 2 located at the two ends of the concrete pile body 1, the end plates 2 are also H-shaped.

[0051] The manufacturing method includes the following steps

[0052] (1), cut the steel strand 3 to a fixed length, and arrange it in the forming position.

[0053] (2), make two locking ...

Abstract

The invention relates to a method for manufacturing an H-shaped pile with steel strands. The H-shaped pile comprises a concrete pile body with the H-shaped cross section, and a reinforcement cage located in the concrete pile body. The reinforcement cage comprises the steel stands and stirrups. By means of the method, it is possible that the steel stands are adopted inside the H-shaped pile as pre-stress main reinforcements; the method is an actual and feasible method for manufacturing the H-shaped pile with the steel strands, and bending resistance, shearing resistance and tensioning resistance of the H-shaped pile are greatly improved; all the steps of the method can be well linked, the manufacturing process is simple and smooth, and manufacturing cost is low; in the tensioning step, each steel strand is tensioned in the tensioning process; compared with an existing overall tensioning method, it can be ensured that each steel strand is accurately tensioned to a specific numerical value.

Description

technical field [0001] The invention belongs to the technical field of pile foundation engineering of various building structure systems, and in particular relates to a manufacturing method of an H-shaped pile with steel strands. Background technique [0002] At present, the more common concrete prestressed piles include pipe piles, square piles, H-shaped piles, etc. Various types of piles have their own characteristics and can be used according to different occasions and environments. Taking the H-shaped pile as an example, it includes a pile body made of prestressed steel bars, stirrups and concrete pouring. The cross section of the pile body is an H-shaped pile composed of two flanges and a web connected between the two flanges. . [0003] The prestressed steel bars in traditional concrete prestressed pipe piles, square piles, and I-shaped piles are steel rods. Because they are prefabricated in factories, the production efficiency is high, the strength of the main reinfo...
