Description

Technical Field

[0001] The utility model relates to the technical field of structural engineering, in particular to an assembled eccentrically supported steel structure. Background Art

[0002] Eccentric bracing involves a structure where the intersection of the support axis and the beam axis is spaced a certain distance from the intersection of the beam and column. The beam segment between these two intersections is known as the energy dissipation beam segment. The primary purpose of eccentric bracing is to dissipate external forces through the energy dissipation beam segment, further contributing to earthquake resistance. This makes it an essential steel structure in seismic zones.

[0003] A search revealed a utility model patent with the publication number CN215888586U, specifically disclosing an assembled eccentrically supported steel structure, comprising two high-strength support columns, each of which is fixedly connected by a connecting crossbeam. A seismic-resistant energy-dissipating beam section is fixedly connected to the center of the bottom of the connecting crossbeam, and an oblique support beam is fixedly connected to the corresponding high-strength support column in the lower half of the energy-dissipating beam section near both sides of the high-strength support column. Energy-dissipating grooves are provided in the upper half of the energy-dissipating beam section near both sides of the oblique support beam, and energy-dissipating parts are provided within the energy-dissipating grooves. Reinforcement grooves communicating with the energy-dissipating grooves are provided in the lower half of the energy-dissipating beam section near both sides of the oblique support beam, and reinforcement metal blocks are provided on the inner periphery of the reinforcement grooves for reinforcement. This assembled eccentrically supported steel structure not only improves seismic resistance but also enhances stability through double connections.

[0004] Although the above patent improves the stability of the steel structure and the seismic resistance of the steel structure through double connection, the steel structure in the above patent still needs to be welded and fixed on the construction site through splicing, and the welded steel structure is hoisted and installed as a whole. Due to the poor construction site environment and the welding done by workers on site, the quality of welding cannot be well guaranteed, which affects the safety performance of the building.

[0005] Therefore, it is necessary to propose an assembled eccentrically supported steel structure to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide an assembled eccentrically supported steel structure, which can facilitate the mutual splicing of beams and I-beam sections through the mutual cooperation between the internal parts of the crossbeam mechanism, and facilitate the welding and fixing of square steel pipes and beams before transportation from the factory. Through the mutual cooperation between the internal parts of the diagonal bracing mechanism, it is convenient for workers to dock and install the supporting I-steel, No. 1 supporting column and No. 2 supporting column on the beams and columns, thereby improving the splicing efficiency of the supporting I-steel, No. 1 supporting column and No. 2 supporting column, so as to solve the problem in the prior art that the construction site environment is poor and the welding is done by workers on site, and the quality of welding cannot be well guaranteed, thereby affecting the safety performance of the building.

[0007] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: an assembled eccentrically supported steel structure, comprising a column body, wherein the top and bottom ends of the column body are provided with a crossbeam mechanism, and are sleeved with the outer wall of the column body, and a diagonal bracing mechanism is provided between the plurality of column bodies, and extends through the interior of the crossbeam mechanism.

[0008] Preferably, the crossbeam mechanism includes a square steel tube, and there are multiple square steel tubes.

A beam column is welded and fixed to one side of the square steel tube, and a connecting column is connected and fixed to the side of the beam column away from the square steel tube. An I-beam section is provided between the beam columns and is socketed with the outer wall of the connecting column. A plurality of flanges are provided at the joints between the beam column and the I-beam section.

[0009] Preferably, the diagonal bracing mechanism includes a supporting I-beam, and there are multiple supporting I-beams. The multiple supporting I-beams are arranged between multiple column bodies and above the beams. The bottom end of the supporting I-beam is fixedly provided with a No. 1 docking column, which passes through the interior of the top end of the beam. A No. 1 supporting column is provided on one side of the top end of the No. 1 docking column, and fits with the bottom end of the connection between the beam and the I-beam section. A No. 2 supporting column is fixed on the side of the top end of the No. 1 docking column away from the No. 1 supporting column, and fits with the connection between the square steel tube and the beam. A No. 2 docking column is fixed on the top end of the No. 2 support column, and passes through the interior of the bottom end of the beam.

The beam column and the supporting I-beam can be installed and fixed by bolts. The installed beam column and I-beam section are suspended above the No. 1 support column and the No. 2 support column by the crane, so that the beam column passes through the No. 2 docking column at the top of the No. 2 support column to complete the docking with the top of the No. 1 support column and the No. 2 support column. The installation connection is completed by using square steel tubes to complete the connection with the top of the column body, and then the installation and fixation between the No. 1 support column, the No. 2 support column, the beam column and the I-beam section are completed by bolts, so that the No. 1 support column provides structural support for the beam column and the square steel tube, and the No. 2 support column provides structural support for the connection between the beam column and the I-beam section, which can improve the structural bearing capacity of the beam column and the I-beam section, and after multiple large parts are spliced ​​and connected to each other, they are installed and fixed by bolts, which can increase the splicing speed between steel structures and improve the structural stability between steel structures.
