Problems solved by technology

During the earthquake, the frame structure is obviously damaged in the beam-column joint area, and considering that the beam-column is a structural component, once the bearing capacity is lost, it is very likely to cause irreversible consequences

Abstract

The invention discloses a friction energy dissipation supporting structure, an assembly type supporting frame system and a construction method. The friction energy dissipation supporting structure comprises an energy dissipation gear assembly, and a first supporting rod, a second supporting rod and two third supporting rods that are connected with the energy dissipation gear assembly. According to the friction energy dissipation supporting structure, a first gear and two second gears that are arranged in a meshed mode are used for forming the energy dissipation gear assembly, the first supporting rod is connected with one second gear, the second supporting rod is connected with the other second gear, the two third supporting rods are connected with the first gear, and an upper beam and a lower beam of a frame form a rigid body; four connecting hinges are used as connecting media of the first supporting rod, the second supporting rod and the third supporting rods and the apical corners of the frame and are hinged to the ends of the first supporting rod, the second supporting rod and the third supporting rods correspondingly, and the two third supporting rods are arranged in the frame in an opposite angle mode; and therefore, when an earthquake occurs, the two third supporting rods convert interlayer earthquake force into tension and pressure to be transmitted, and friction can also be generated between the first gear and the second gears so as to consume earthquake energy.

Description

technical field [0001] The present disclosure generally relates to the technical field of prefabricated buildings, and specifically relates to a frictional energy-dissipating support structure, a prefabricated support frame system and a construction method. Background technique [0002] my country is located between the world's two major earthquake zones and is one of the countries with many earthquakes. Earthquakes are characterized by strong suddenness and great destructiveness. There are three main ways to prevent earthquake disasters in current construction projects, namely, anti-seismic, seismic isolation and shock absorption. Seismic resistance is to increase the amount of materials used in building structures so that the structure itself has sufficient ability to resist earthquakes. At present, the main method of seismic resistance in my country is to carry out seismic design of building structures. Seismic isolation is to set a seismic isolation layer between the to...
