Novel friction device for seismic resistance of prefabricated building

Abstract

The invention relates to the field of constructional engineering, and discloses a novel friction device for seismic resistance of a prefabricated building. The novel friction device comprises a rotating device, a friction round block is mounted in steel outer discs, an inner fixing part is arranged on the inner side of the friction round block, outer fixing parts are arranged on the outer sides of the steel outer discs, high-strength bolts are mounted on the outer sides of the centers of the outer fixing parts, rectangular iron blocks are connected to one sides of the steel outer discs, and foot binding bolts are mounted at the two ends of the rectangular iron blocks. The friction device is mounted at the connecting position of a beam and a column, the two steel outer discs are fixed to the beam and the column through the foot binding bolts correspondingly, then the steel outer discs and all the parts are fixed through the high-strength bolts, relative rotation of the beam and the column interface under the vibration effect can cause the surface of the friction round block in the friction device to rotate and slide, and therefore energy is dissipated; and the possibility of top displacement and structure dame is reduced, and the problems that the life and property safety of people is affected, and the mounting process is complex due to the fact that an existing novel friction device for seismic resistance of the prefabricated building is low in cushioning efficiency are solved.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a novel friction device for anti-seismic use of prefabricated buildings. Background technique [0002] Earthquake-resistant buildings refer to the earthquake-resistant design of buildings in areas with an earthquake-resistant fortification intensity of 6 degrees and above. In major earthquake disasters around the world, more than 95% of casualties are caused by damaged or collapsed buildings. The most direct and effective way to reduce earthquake disasters is to explore the causes of buildings being damaged and collapsed in earthquakes, and to take precautions. Improving the seismic performance of buildings is one of the main measures to improve the city's comprehensive defense capability, and it is also a major task of "resistance" in the work of earthquake prevention and disaster reduction. Prefabricated buildings refer to concrete beams, slabs, columns and other compon...
