T-shaped node of steel concrete combined pipe assembled by T-shaped steel and threaded sleeve pipe

Abstract

The invention relates to a T-shaped node of a steel concrete combined pipe assembled by T-shaped steel and threaded sleeve pipe, which comprises a first steel concrete combined pipe and a second steelconcrete combined pipe, wherein an end steel plate is exposed at the rear end part of a second rectangular steel plate structure; an internal threaded sleeve is embedded in the front side of the first steel concrete combined pipe; the front half section of the internal threaded sleeve is in threaded connection with a connecting stud; the back side of the end steel plate is welded with two T-shaped steels. The back side of the web of each T-shaped steel is provided with a wrench operation hole corresponding to an installation hole. The front end of the connecting stud is threaded with a connecting nut in the operation hole of the wrench, the back side surface of the wing plate is pressed on the front side surface of the first steel concrete composite pipe by the connecting nut. The node can greatly improve the connection strength of T-shaped nodes between the two steel concrete combined pipes and ensure the reliability of the connection, combines cast-in-place casting and prefabrication, is convenient for construction, has high construction efficiency, can ensure the construction quality, and completely meets the use requirements of integral stress, energy saving, earthquake resistance and the like of modern assembled buildings.

Description

technical field [0001] The invention belongs to the technical field of prefabricated building construction, and in particular relates to a T-shaped joint of a steel-concrete composite pipe assembled and connected by a T-shaped steel and a threaded casing. 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 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 earthquake resistance, and easy The shortcomings of causing deformation and cr...

[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.
