Technical Field

[0001] The utility model relates to the technical field of connection between a steel structure column and a steel structure beam, in particular to a connection node between a steel structure column and a steel structure beam. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields.

[0003] After searching, the utility model patent with the Chinese patent publication number CN212153749U discloses a prefabricated steel structure beam-column connection node, including a steel column and a steel beam, wherein the steel column is composed of a column wing plate and a column web plate, wherein the column web plate is located between two column wing plates, and a counterweight is installed inside the steel column. In the utility model, a counterweight is installed inside the steel column, and a mounting groove is provided inside the counterweight, and one end of the mounting groove is open. By providing the mounting groove, when the steel column is connected to the steel beam, the staff inserts one end of the steel beam into the mounting groove through a tool, and this method is convenient for inserting the steel beam into the steel column, thereby improving the integrity between the steel beam and the steel column, and improving the stability of the connection. At the same time, a pre-embedded hole is provided on the surface of the steel beam and the counterweight, and by providing the pre-embedded hole, after the steel beam and the counterweight are connected, the staff inserts the pre-embedded steel bar prepared in advance into the pre-embedded hole, and this method is convenient for fixing the counterweight and the steel beam, thereby improving its overall performance.

[0004] After searching the above patents, it was found that the stability of the beam-column connection was dealt with, but most of the existing steel structure columns and beams are I-shaped, and the installation scheme used by the device requires processing components such as counterweight grooves on the I-shaped steel structure, which results in poor applicability and low installation efficiency during actual installation.
