Description

Technical Field

[0001] This utility model relates to a beam-column connection structure, and more particularly to a connection structure between a reinforced concrete beam and a column. Background Technology

[0002] With the continuous development of building science and technology, the structural systems of high-rise buildings have gradually shifted from traditional reinforced concrete systems to steel structure systems. Steel structures, due to their advantages such as fast construction speed, good seismic resistance, high strength, and light weight, have been rapidly and widely adopted in the construction industry. During steel structure construction, the connection methods between reinforced concrete beams and steel columns or steel-concrete composite columns include straight threaded sleeve connections, column opening connections, and welded connecting plates or corbel connections. These connection methods are difficult to construct, require high precision, and all necessitate appropriate connection treatment between the reinforced concrete beams and steel columns or steel-concrete composite columns. When the reinforcement within the reinforced concrete beam is dense, it can even make on-site construction difficult. Therefore, existing technologies suffer from high construction difficulty and are time-consuming and labor-intensive. Summary of the Invention

[0003] The purpose of this invention is to provide a connection structure between reinforced concrete beams and columns. This invention effectively reduces construction difficulty and saves time and labor during construction.

[0004] The technical solution of this utility model is as follows: A connection structure between a reinforced concrete beam and a column, comprising a column body (either a steel column or a steel-concrete composite column) and a reinforced concrete column, wherein a reinforced concrete beam is provided between the column body and the reinforced concrete column, and the column body is provided with H-shaped steel ribs on its side, the H-shaped steel ribs extending into the reinforced concrete beam; the H-shaped steel ribs are provided with longitudinal stiffening ribs and transverse stiffening ribs, upper studs are provided above the upper flange of the H-shaped steel ribs, lower studs are provided below the lower flange, and web studs are provided at the web of the H-shaped steel ribs.

[0005] In the aforementioned connection structure between a reinforced concrete beam and a column, the length of the H-shaped steel frame extending into the reinforced concrete beam is one-third of the distance between the axis of the column and the axis of the reinforced concrete column, and the H-shaped steel frame is centrally arranged within the reinforced concrete beam.

[0006] In the aforementioned connection structure between a reinforced concrete beam and a column, the distance between the edge of the H-shaped steel frame and the edge of the reinforced concrete beam is not less than 100mm.

[0007] In the aforementioned connection structure between a reinforced concrete beam and a column, the length of the longitudinal stiffening rib is equal to the height of the H-shaped steel frame.

[0008] In the aforementioned connection structure between a reinforced concrete beam and a column, there are multiple transverse stiffening ribs, and their spacing is equal to the height of the H-shaped steel frame.

[0009] In the aforementioned connection structure between a reinforced concrete beam and a column, the upper flange of the H-shaped steel frame is provided with two rows of evenly distributed upper studs, and the lower flange of the H-shaped steel frame is provided with two rows of evenly distributed lower studs.

[0010] In the aforementioned connection structure between a reinforced concrete beam and a column, the web studs include first studs located on the upper and lower sides of the longitudinal stiffeners and second studs located on the sides of the transverse stiffeners, and both the first and second studs are fixed to the web of the H-shaped steel frame.

[0011] In the aforementioned connection structure between a reinforced concrete beam and a column, the reinforced concrete beam is provided with upper longitudinal bars, lower longitudinal bars, web bars, and denser stirrups.

[0012] Compared with existing technologies, this utility model consists of a steel column or steel-concrete composite column, an H-shaped steel frame fixed to the steel column or steel-concrete composite column, a reinforced concrete beam, and a reinforced concrete column. The H-shaped steel frame extends into the reinforced concrete beam (connecting the steel column or steel-concrete composite column to the reinforced concrete beam), and longitudinal stiffening ribs and transverse stiffening ribs are provided on the H-shaped steel frame. Studs are installed within the upper and lower flanges, longitudinal stiffening ribs, and transverse stiffening ribs, thereby effectively improving the structural strength. This utility model uses an H-shaped steel frame fixed to the steel column or steel-concrete composite column that extends into the reinforced concrete beam, avoiding the operation of connecting the longitudinal reinforcement of the reinforced concrete beam to the steel column. After the H-shaped steel frame is processed in the factory, it is positioned, hoisted, and fixed on the construction site. The reinforcement of the corresponding position of the reinforced concrete beam can be tied according to conventional methods. It is not necessary to weld threaded sleeves, connecting plates, corbels, or make holes on the steel column or steel-concrete composite column for connection to the reinforced concrete beam. It has the characteristics of simple structure, good integrity, convenient construction, and time saving. In summary, this utility model has the advantages of effectively reducing construction difficulty and saving time and effort during construction. Attached Figure Description
