Swing type energy dissipation and shock absorption mechanism suitable for fabricated building

Abstract

The invention provides a swing type energy dissipation and shock absorption mechanism suitable for a fabricated building. The swing type energy dissipation and shock absorption mechanism comprises an upper-layer structure, a lower-layer structure and a buffering mechanism for connecting the upper-layer structure with the lower-layer structure; and the buffering mechanism comprises a damping box connected with the lower-layer structure, a cavity is formed in the damping box, an opening of the cavity is located in the upper end of the damping box, damping liquid is arranged in the cavity, a rotating mechanism is arranged at the upper end of the damping box, a swing part is arranged on the rotating mechanism, the lower portion of the swing part extends into the cavity, a semicircular first transmission part is arranged at the upper end of the swing part, and a second transmission part matched with the first transmission part is arranged at the lower portion of the upper-layer structure. By means of the swing type energy dissipation and shock absorption mechanism, horizontal kinetic energy of the adjacent upper-layer and lower-layer structures can be converted into swing kinetic energy, and the swing kinetic energy is converted into heat energy in the form of shearing the damping liquid so as to achieve the energy consumption and buffering effects.

Description

technical field [0001] The invention relates to the technical field of energy-dissipating buffers in the field of anti-seismic and wind-resistant buildings, in particular to a swing-type energy-dissipating and shock-absorbing mechanism suitable for assembled buildings. Background technique [0002] Compared with traditional cast-in-place reinforced concrete and masonry buildings, prefabricated buildings use building components including beams, slabs, columns and exterior walls produced in the factory, and then transported to the site for installation and construction after maintenance and acceptance. way of building. With the "standardization" of building components and the "industrialization" of construction methods, traditional buildings have been completely subverted. But at the same time, there are many problems that cannot be underestimated. The controllability of prefabricated buildings in the construction process is lower than that of traditional cast-in-place reinfo...

Problems solved by technology

[0005] Moreover, the wall damper does not have any release or buffer in the horizontal direction perpendicular to the shear direction, and it is easy to get stuck under the action of an earthquake. However, when the wall damper is tested in the laboratory, only the performance in the shear direction is tested. Does not consider the influence of the horizontal direction perpendicular to the shear direction, which is quite different from the actual application
