Symmetric rotating type energy dissipation connecting piece

Abstract

The invention relates to a symmetric rotating type energy dissipation connecting piece which can be used for connecting prefabricated assembly type building structural components and can reduce the influence of small relative displacement between the components. The symmetric rotating type energy dissipation connecting piece symmetric rotating type energy dissipation connecting piece comprises moving plates, a rotating plate, a shear type metal energy dissipation material, a viscoelastic energy dissipation material and bolts. According to the symmetric rotating type energy dissipation connecting piece, amplification is performed as required when small displacement occurs between the components while the different components can be connected, and thus the energy dissipation capacity of the materials is brought into full play. That is, when the building components on the left side and the right side are subjected to relative displacement, relative displacement occurs between the moving plates on the two corresponding sides; under the driving of the bolts on the two sides, the rotating plate rotates with its centroid as the rotating center, and the energy dissipation materials are driven to deform, so that energy dissipation is achieved. The symmetric rotating type energy dissipation connecting piece has the advantages of being small in size, symmetric and reasonable in structure and simple to install, running stably and being high in durability; and the symmetric rotating type energy dissipation connecting piece is an efficiently energy-dissipating connecting element.

technical field [0001] The invention is a connecting piece with energy dissipation function, which can connect prefabricated components in prefabricated buildings and reduce the influence caused by small relative displacements between components. Background technique [0002] The energy-dissipating and shock-absorbing technology of structures is to set energy-dissipating ( Damping) device (or element), through the energy dissipation (damping) device to produce friction, bending (or shearing, torsion) elastic-plastic (or viscous, viscoelastic) hysteretic deformation to dissipate or absorb the action caused by external force and earthquake Or wind load and other energy input into the structure to reduce the seismic response of the main structure, so as to avoid structure damage or collapse, and achieve the purpose of shock absorption control. Energy-dissipating shock absorbers can be manufactured with different materials, different energy-dissipating mechanisms, and different...

Problems solved by technology

At the same time, the existing energy-dissipating devices occupy a large overall space or require a more complex support system, which affects the space efficiency of the building and also affects the overall stiffness of the structure, so it is often limited in practical applications
