T-shaped node of steel bar framework, screw rod and C-shaped steel concrete combined pipe

Abstract

The invention relates to a T-shaped node of a steel bar framework, screw rod and C-shaped steel concrete combined pipe, which comprises a first steel concrete combined pipe and a second steel concretecombined pipe, wherein the rear end part of a second rectangular steel plate structure is opened; the C-shaped steel is vertically arranged and opened forwards; the front side of the C-shaped steel is welded with the rear side of the 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 sectionof the internal threaded sleeve is in threaded connection with a connecting screw rod; the front end of the connecting screw rod is connected with the C-shaped steel through a connecting nut; a wrench operating hole is formed in the left side and right side of the C-shaped steel, at the positions corresponding to connecting nut, a steel mesh framework is arranged between the back side of C-shapedsteel and 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 andensure 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 steel-concrete composite pipe T-shaped joint of a reinforced skeleton, a screw rod and a C-shaped steel combined type. 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 ...

[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.
