Description

Technical Field

[0001] The utility model relates to the technical field of building components, in particular to a reinforced concrete structure beam-column node. Background Art

[0002] The beam-column node is a crucial connection point in reinforced concrete structures, and bears the important responsibility of transferring loads, ensuring structural stability and improving seismic performance. Its structure includes components such as beams, columns, node plates, steel bars and concrete. The beam is responsible for bearing the floor slab and other loads, and transferring them to the columns, while the columns transfer the loads to the foundation. The node plate connects the beam and the column, and is responsible for load transfer. It is usually made of reinforced concrete or steel plates. In order to enhance the bearing capacity and seismic performance of the node, a large amount of steel bars are usually added at the node. High-quality concrete and reasonable reinforcement can improve the durability and seismic performance of the node;

[0003] For example, a reinforced concrete structure beam-column node disclosed in the authorization announcement number CN220353064U includes a column and a beam, longitudinal bars and H-shaped steel are reserved at the top of the column, and longitudinal bars are arranged on both sides of the web of the H-shaped steel; the beam includes transverse bars and stirrups, the transverse bars are connected to the web of the H-shaped steel through a steel sleeve, and the stirrups are tied to the transverse bars; the connection between the column and the beam is roughened and connected as a whole by pouring concrete, and the steel bars are connected by steel sleeves without overlapping the steel bars, which effectively reduces the use of steel bars and saves the cost of using steel bars. However, this technical solution is mainly a two-way connection structure form of the same axis, that is, the connection between two beam-column nodes in the same X-axis or Y-axis direction, and the structural design of the building needs to have a more flexible node connection method. For example, when the design requires the node to be connected in four directions, this structural form cannot meet the requirements. In this case, the staff needs to reconsider the layout and connection method of the node, thereby introducing a more complex structural design, which increases the design difficulty and the cost of using the beam-column node.
