Technical Field

[0001] The utility model relates to a beam-column node of a double-beam steel structure, belonging to the technical field of double-beam steel structures. Background Art

[0002] Double-beam steel structure refers to a steel structure design in which two beams are arranged above and below the same position. This design requires defining the correct elevation and arranging them in layers 1 and 2 respectively to ensure the stability and load-bearing capacity of the structure. Double-beam steel structure has a wide range of applications, including but not limited to antique buildings, bridge cranes and other fields. Double-beam steel structure requires the beams and columns to be fixed.

[0003] According to the announcement number CN221646039U, a double-beam steel structure beam-column node relates to the field of steel structure technology and aims to improve the uneven quality of welds that affects the stability of the connection and the problem that welding technology is difficult to repair or replace after an earthquake. A double-beam steel structure beam-column node includes a square steel pipe column and a double I-beam arranged on the column. The connection between the I-beam and the square steel pipe column is connected by a fixed collar, and a tensioning member is arranged above the square steel pipe column to connect the outer ends of the double beams. The present application has the effect of improving the stability of the connection between the square steel pipe column and the steel beam, and reduces the construction difficulty. When installing the above-mentioned device, workers need to carry a large number of bolts, and then insert the bolts one by one and tighten them with nuts, which makes the installation efficiency of the device low. In addition, during the installation process, it is easy for workers to slip and cause the bolts to fall, and then workers need to climb back and forth, which makes the installation of the device more inconvenient.
