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

Abstract

The invention relates to a T-shaped node of a steel concrete combined pipe assembled by long channel steel and a threaded sleeve, which comprises a first steel concrete combined pipe and a second steel concrete combined pipe, wherein the rear end part of a second rectangular steel plate structure exposes an end steel plate; 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 screw rod; the rear side surface of the end steel plate is welded with thelong channel steel; the left side and right side of the long channel steel are provided with transparent mounting holes respectively, the mounting holes and the internal threaded sleeve are in one-to-one correspondence, the front end of a connecting screw rod passes through the mounting holes and is threaded with a connecting nut, the connecting nut presses the rear side of the channel steel on the front side surface of the first steel concrete combined pipe. According to the invention, the node can greatly improve the connection strength of T-shaped nodes between the two steel concrete combined pipes and ensure the reliability of 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 combined steel concrete combined pipe of long-shaped steel and threaded casing. Background technique [0002] The single-section steel-concrete composite pipe used in the prefabricated building 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 the existing prefabricated building is the inability to form a stable and unified system. The key to the problem lies in the connection of nodes 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 poor structural integrity, poor seismic resistance, and easy It causes the shortcomings of prefabricated wall deformation a...

[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.
