Description

Technical Field

[0001] The utility model relates to the technical field of building steel structures, in particular to a column earthquake-resistant steel structure for construction engineering. 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 frames and other components made of steel sections and steel plates. 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, stadiums, super high-rise buildings and other fields; the above technical solutions in the prior art can only improve the strength, impact resistance and fracture resistance of building steel structures. However, buildings near earthquake zones have very high requirements for earthquake resistance to prevent the steel structure from being damaged during earthquakes and avoid the loss of personnel and property. However, the building steel structure in the prior art cannot meet the requirements for high earthquake resistance. For this reason, we propose a column earthquake-resistant steel structure for construction projects.

[0003] A Chinese patent discloses a column-type earthquake-resistant steel structure for construction engineering (authorization announcement number CN216475541U). The patented technology can be provided with a base and a mounting groove at the base position, and the outer surface of the fixing ring is placed in the mounting groove to align the first threaded hole and the through hole, and then the base and the mounting seat are fixed by passing the fastening bolt through the through hole and threadedly connected with the first threaded hole, and then the support column is held and threadedly connected with the second threaded hole through the second threaded column to complete the installation of the device. The installation is convenient and quick, and the use is convenient; however, the base of the device is small and the stability is not high; and the device is time-consuming and laborious to disassemble, which wastes time.
