Abstract

The invention discloses a beam and board separating type layering shock isolation structure which comprises a framework and a framework shear wall. Building boards in the framework and the framework shear wall are supported on a beam through multiple rubber shock isolation supports. Common laminating rubber supports, pencil lead rubber supports and high-damping rubber supports can be selected as the rubber shock isolation supports. Shock isolation seams are formed between the building boards and columns of the framework and the framework shear wall, or high-damping rubber is filled into the positions between the building boards and the columns of the framework and the framework shear wall. The rubber shock isolation supports can be arranged layer upon layer in the height direction according to the shock isolation target, and can also be only arranged under some building boards. According to the structure, main quality building boards of a building are isolated through the rubber shockisolation supports, and the shock isolation effect is good. While shock isolation is achieved, a lateral force resisting component is not disconnected, the integrality and the stability are better, and the application range is wider. In addition, the structure also has a certain shock isolation effect on wind vibration, machine vibration and the like.

Description

[0001] The invention relates to a beam-slab separation type layered seismic isolation structure, which belongs to the technical field of building seismic isolation and energy consumption and damping. Background technique [0002] The principle of the seismic isolation technology is to increase the natural vibration period of the building and reduce the seismic effect by setting the seismic isolation support with lower lateral stiffness. The principle is clear, and the effect of shock isolation and shock absorption is very obvious. [0003] At present, seismic isolation technology can be divided into two categories. One is base isolation, that is, isolation supports are arranged on the top of the foundation to limit the seismic energy from entering the superstructure; the other is layer isolation, that is, isolation is placed on a certain floor of the building. Earthquake support reduces the seismic effect of floors above the seismic isolation support. Frames and frame shear walls ...
