T-shaped node of steel concrete combined pipe with high shear strength

Abstract

The invention relates to a T-shaped node of a steel concrete combined pipe with high shear strength, which comprises a first steel concrete combined pipe and a second steel concrete combined pipe, wherein an end steel plate is exposed at the rear end portion of a second rectangular steel plate structure; an internal threaded sleeve is embedded in the front side of the first steel concrete combinedpipe; the front half section of the internal threaded sleeve is in threaded connection with a connecting stud; the rear side of the end steel plate is welded with a vertically arranged grooved steelplate; the left side plate of the grooved steel plate and the rear side of the right side plate are welded with a connecting plate; a plurality of anti-shear rod pieces are arranged in the grooved steel plate and are connected to the first steel truss combined pipe; the anti-shear rod pieces are evenly arranged in the vertical direction and are located between the left and right internal threadedsleeve. The T-shaped node of the steel concrete combined pipe with high shear strength can greatly improve the connection strength of T-shaped node between the two steel concrete combined pipes and ensure the reliability of connection; cast-in-place casting and prefabrication are combined, construction is convenient, construction efficiency is high, thereby ensuring the construction quality, and completely meeting 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 steel-concrete composite pipe T-shaped node with high shear strength. 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 deformation and cracks of the fabricated wall, and its connect...

[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.
