Threaded sleeve and T-shaped node of short U-shaped steel connection type steel concrete combined pipes

Abstract

The invention discloses a threaded sleeve and T-shaped node of short U-shaped steel connection type steel concrete combined pipes. The threaded sleeve and the T-shaped node comprise a first steel concrete combined pipe and a second steel concrete combined pipe, wherein the first steel concrete combined pipe and the second steel concrete combined pipe are vertically arranged mutually; an end steelplate is exposed from the rear end of the second steel concrete combined pipe; an internal thread sleeve is embedded in a first concrete layer at the front side of the first steel concrete combined pipe; the front half section of the internal thread sleeve is in threaded connection with a connecting screw rod; the rear side surface of the end steel plate is welded to a U-shaped steel; installationholes are formed in the left side and right side of the U-shaped steel; and the front end of the connecting screw rod penetrates through the installation holes and connects the U-shaped steel integrally. The threaded sleeve and the T-shaped node can greatly improve the connection strength of the T-shaped node between the two steel concrete combined pipes, ensures the reliability of connection, combines a cast-in-place mode and prefabrication, is convenient for construction, has high construction efficiency, ensures the construction quality, and completely meets the use requirements of integral stress, energy saving, earthquake resistance and the like of modern assembly-type buildings.

Description

technical field [0001] The invention belongs to the technical field of prefabricated building construction, and in particular relates to a threaded casing and a T-joint of a steel-concrete composite pipe connected with short square-shaped steel. Background technique [0002] The single-section steel-concrete composite pipe used in prefabricated buildings has a rectangular cylindrical structure as a whole. After being manufactured in the factory, it is transported to the construction site for assembly. The biggest problem in the promotion and application of existing prefabricated buildings is that it cannot form a stable and unified system. The key to the problem lies in the joint connection between the steel-concrete composite pipes. The T-joint is one of the most common joints in prefabricated buildings. Most of the existing T-joint structures have weak structural integrity, poor seismic resistance, and easy The shortcomings of the prefabricated wall deformation and cracks ...

[0002] The single-section steel-concrete composite pipe used in prefabricated buildings has a rectangular cylindrical structure as a whole. After being manufactured in the factory, it is transported to the construction site for assembly. The biggest problem with the popularization and application of existing prefabricated buildings is that they cannot form a stable and unified system. The crux of the problem lies in the node connection between steel-concrete composite pipes. T-shaped joints are one of the most common joints in prefabricated buildings. Most of the existing T-shaped joints have weak structural integrity, poor seismic resistance, and easy The shortcomings of causing deformation and cracks in the prefabricated wall, and its connection form cannot meet the higher requirements of the prefabricated building.
