A 3D Vibration Isolation/Seismic Bearing with Decoupled Horizontal Bidirectional and Vertical Deformation

Abstract

The invention discloses a three-dimensional vibration isolation / seismic support for horizontal bidirectional and vertical deformation decoupling, including a horizontal vibration isolation support, a vertical vibration isolation support and a deformation decoupling device, the horizontal vibration isolation support and The vertical vibration isolation support is arranged in series in the vertical direction. The vertical vibration isolation support includes an upper positioning steel plate, a lower positioning steel plate and a vertical vibration isolation unit. The deformation decoupling device can realize three-dimensional horizontal and vertical deformation. Decoupling, the deformation decoupling device is composed of horizontal limit corner columns, horizontal shear steel plates and vertical deformation gaps. The present invention can realize the three-dimensional decoupling of the horizontal deformation of the horizontal vibration isolation bearing and the vertical deformation of the vertical vibration isolation bearing, ensuring that the horizontal deformation of the three-dimensional vibration isolation / seismic isolation bearing only occurs in the horizontal vibration isolation bearing , The vertical deformation only occurs in the vertical vibration isolation bearing, which effectively improves the vibration isolation (seismic) effect of the three-dimensional vibration isolation (seismic) bearing.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a three-dimensional vibration isolation / seismic support decoupled from horizontal bidirectional and vertical deformations. Background technique [0002] The construction of urban underground rail transit has achieved rapid development in major cities in my country in recent years. With its advantages of "low pollution, large transportation volume, and convenience", it has become an effective means to solve the problem of urban congestion. At this stage, major domestic cities are vigorously promoting the construction of urban underground rail transit and underground multi-functional comprehensive transportation hubs. However, the subway line is getting closer and closer to the building structure. The high-speed operation of the subway, braking, and start-up acceleration will cause problems such as vertical vibration and noise exceeding the limit of the adjacent buildin...

[0011] The purpose of the present invention is to propose a three-dimensional vibration isolation / seismic support that decouples horizontal bidirectional and vertical deformations, which can effectively solve the problem of horizontal and vertical vibration when the horizontal vibration isolation support and the vertical vibration isolation support are used in combination. The detrimental effect of the coupling effect of deformation on the horizontal and vertical vibration isolation results, so that the horizontal deformation and vertical deformation of the support do not affect each other, and the extremely efficient horizontal vibration isolation effect and vertical vibration isolation effect are realized. vibration effect
