Pre-buried steel sleeve joint structure between prefabrication tube pile and prefabrication bearing platform

Abstract

The invention discloses a pre-buried steel sleeve joint structure between a prefabrication tube pile and a prefabrication bearing platform, which includes a prefabrication bearing platform component A, a prefabrication tube pile component B, a steel sleeve joint component C and a connection part D, wherein the prefabrication bearing platform component A and the steel sleeve joint component C are integrally prefabricated into a bearing platform component with a joint; the connection part D is used for connecting the prefabrication tube pile component B with the bearing platform component prefabricated with the joint into a whole. The pre-buried steel sleeve joint structure has the following beneficial effects: joint integrity and reliability are improved through preserved connecting reinforcement and top injection, an inner sleeve and reinforcing ribs are arranged inside the joint structure to effectively improve the bending resistance and shear-bearing capacity of the joint position; the structure is safe and reliable, the construction is convenient and quick, and the prefabrication efficiency is high; the pre-buried steel sleeve joint structure between the prefabrication tube pileand the prefabrication bearing platform is clear and direct in force transmission, the welding quality is controllable, the connection integrity of the prefabrication tube pile and the prefabricationbearing platform is enhanced, the bending resistance and shear-bearing capacity of the joint position are improved, the factory machining and on-site construction are convenient and simple, and the quality is easily guaranteed.

Description

technical field [0001] The invention relates to a connection structure between a railway pipe pile and a cap; in particular, it relates to a joint structure of a prefabricated steel sleeve between a prefabricated pipe pile and a prefabricated cap. Background technique [0002] The current codes and atlases mostly use core-filled concrete cast-in-place schemes for the connection between prefabricated pipe piles and cast-in-place caps. The shear resistance is poor, the site has a large amount of wet work, and it is not suitable for the connection between the prefabricated pipe pile and the prefabricated cap. At present, the prefabricated structure has good development prospects due to its advantages of high industrialization efficiency, high production quality, convenient construction, and fast construction speed, and has been widely used all over the country. A connecting structure capable of reliably connecting prefabricated parts. Contents of the invention [0003] The ...
