Steel reinforced concrete column-steel reinforced concrete inclined beam T-shaped joint

Abstract

The invention discloses a steel reinforced concrete column-steel reinforced concrete inclined beam T-shaped joint which is formed by fixedly connecting a steel reinforced concrete column with a steel reinforced concrete beam. In-beam H-shaped steel is arranged in the steel reinforced concrete beam, in-column H-shaped steel is arranged in the steel reinforced concrete column, one or more in-beam longitudinal ribs needing to penetrate flanges of the in-column steel is arranged along an upper flange and a lower flange of the in-beam H-shaped steel respectively, in-beam longitudinal ribs penetrating a joint area are arranged in the steel reinforced concrete beam, longitudinal ribs needing to penetrate the flanges of the in-beam steel and in-column longitudinal ribs penetrating a joint area are arranged in the steel reinforced concrete column, and an upper reinforcing rib and a lower reinforcing rib are arranged in the steel reinforced concrete beam at a position where the steel reinforced concrete beam is connected with the steel reinforced concrete column. The steel reinforced concrete column-steel reinforced concrete inclined beam T-shaped joint is high in rigidity, high in strength and high in ductility, and stress concentration caused by the fact that holes are formed in the steel flanges and webs can be avoided; by arranging an included angle between the beam and the column, process requirements on complex and specific structure of a main workshop of a nuclear power plant can be met, and the joint is worthy of popularization.

Description

technical field [0001] The invention relates to a steel concrete column-shaped steel concrete inclined beam T-shaped joint. This node is used on bent frames and frame intermediate columns. Background technique [0002] With the development of society, the capacity of nuclear power plant units is increasing. In order to improve the characteristics of high cost, poor fire resistance and corrosion resistance of steel structures, it is necessary to adopt steel concrete frame bent structure. Due to the complex process of the main building of nuclear power plants, in order to meet the Due to the technical and drainage requirements, the structure of the main powerhouse is irregular. In this case, since the beams and columns in the conventional joints are arranged vertically, the limitation of the structure itself makes it unable to meet the requirements of the above-mentioned main building although it meets the seismic requirements of bearing capacity and deformation. Process requ...

[0002] With the development of society, the capacity of nuclear power plant units is increasing. In order to improve the characteristics of high cost, poor fire resistance and corrosion resistance of steel structures, it is necessary to adopt steel concrete frame bent structure. Due to the complex process of the main building of nuclear power plants, in order to meet the Due to the technical and drainage requirements, the structure of the main powerhouse is irregular. In this case, since the beams and columns in the conventional joints are arranged vertically, the limitation of the structure itself makes it unable to meet the above-mentioned main powerhouse requirements although it meets the seismic requirements for both bearing capacity and deformation. Process requirements and drainage requirements for the specific structure of the plant
