Building pipe pile with built-in reinforcing ribs

Abstract

The invention discloses a building pipe pile with built-in reinforcing ribs, and belongs to the field of building construction. According to the technical scheme, the building pipe pile is characterized by comprising a pipe pile outer layer, a supporting inner pipe and a reinforcing rib set, wherein the supporting inner pipe is fixedly connected to the inner wall of the pipe pile outer layer, thereinforcing rib set is detachably connected to the inner wall of the supporting inner pipe, four fixing ribs which are annularly distributed with the circle center of the supporting inner pipe as thecenter are fixedly connected to the outer wall of the supporting inner pipe, and four positioning grooves which are annularly distributed with the circle center of the supporting inner pipe as the center are formed in the inner wall of the supporting inner pipe; and the four positioning grooves are formed in the inner wall of the pipe pile, the reinforcing rib set is additionally arranged inside in a detachable connection mode, a plurality of rectangular holes are further formed in the surface of the reinforcing rib set, the reinforcing rib set can be filled with pouring materials, the strength of the pipe pile is improved, a reinforcing mesh is poured through a mold to form the supporting inner pipe, reinforcing bars are placed in positioning circular grooves in the outer wall of the supporting inner pipe for secondary pouring to form the pipe pile outer layer, and the strength of the pipe pile is better guaranteed through the reinforcing rib set.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a building pipe pile with built-in reinforcing ribs. Background technique [0002] At the end of the 1960s, the Fengtai Bridge Factory of the Ministry of Railways began to produce pre-tensioned prestressed concrete pipe piles, which were mainly used for the foundation construction of railway bridge projects; in the 1970s, post-tensioned prestressed concrete pipe piles were developed and produced. Since the 1970s, Especially in the construction of Shanghai Baoshan Iron and Steel Works, a large number of steel pipe piles imported from Japan were used. Not only the cost is high, but the durability is also poor. Concrete PC pipe piles, prestressed concrete thin-walled pipe piles and high-strength prestressed concrete pipe piles, pretensioned prestressed pipe piles are hollow cylindrical slender concrete made by pretensioning prestressing technology and centrifugal for...

AI Technical Summary

Problems solved by technology

[0003] The existing technology has the following problems: In order to improve the strength of the hollow pipe pile, some special materials are often added to the wall of the hollow pipe pile, so that the hollow pipe pile can reach the proper mechanical strength, and it is necessary to use a vibrating cement to fill the interior firmly. Otherwise, its strength will be affected; and the whole mold is poured in the hollow pipe pile, which is difficult to solidify quickly
