Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Such as figure 1 and figure 2 As shown, a prefabricated part with a hollow structure includes a pile body 10, and the pile body 10 is provided with a reinforcement cage 20 fixedly connected with the pile body 10, and the reinforcement cage 20 includes several longitudinal reinforcement bars 21 and longitudinal reinforcement bars 21 The helical spiral steel bar 22 that is fixedly connected, the reinforcement cage 20 is used for enhancing the intensity of pile body 10, also has hollow pipe body 11 in described pile body 10, and the two ends of described hollow pipe body 11 are sealed so that A solid pile 100 is formed between the end of the hollow pipe body 11 and the end of the pile body 10, that is to say, the solid pile 100 is a part of the pile body 10, the hollow pipe body 11 is located in the middle of the two solid piles...

Abstract

A prefabricated member having a hollow structure, comprising a pile body (10). A reinforcement cage (20) and a hollow pipe body (11) are disposed in the pile body (10). Two ends of the hollow pipe body (11) are sealed, such that a solid pile (100) is formed between the end portion of the hollow pipe body (11) and the end portion of the pile body (10). The pile body (10) comprises a plurality of large section piles (12) and small section piles (13) connected to each other. Two ends of the pile body (10) are provided with a recess (41) and a protrusion (42) for engaging with each other. The end portion of the prefabricated member is firm, and the connection is convenient.

Description

technical field [0001] The invention belongs to the technical field of prefabricated parts in the construction industry, and relates to a prefabricated pile, in particular to a prefabricated part with a hollow structure. Background technique [0002] Due to the relatively poor quality stability of immersed tube piles, prefabricated prestressed concrete piles have developed rapidly in recent years. In the piling process, piles of different lengths should be selected according to different needs, which requires the piles to be connected to each other to form a longer pile body. Existing prefabricated parts are usually made by centrifugal forming. During the centrifugation process, a cylindrical hollow structure will be formed in the middle of the pile body. This hollow structure runs through the entire pile body. When the ends of the pile body are connected to each other, the hollow structure will The strength of the connection end is weakened.
