Abstract

The invention discloses a three-dimensional vibration isolation / shock support with horizontal bidirectional and vertical deformation decoupling. The three-dimensional vibration isolation / shock support comprises a horizontal vibration isolation support, a vertical vibration isolation support and a deformation decoupling device, wherein the horizontal vibration isolation support and the vertical vibration isolation support are arranged in series in the vertical direction; the vertical vibration isolation support comprises an upper positioning steel plate, a lower positioning steel plate and a vertical vibration isolation unit; the deformation decoupling device can realize three-dimensional decoupling of horizontal bidirectional and vertical deformation; and the deformation decoupling device is composed of a horizontal limiting corner post, a horizontal shear-resistant steel plate and a vertical deformation gap. According to the three-dimensional vibration isolation / shock support, three-dimensional decoupling of horizontal deformation of the horizontal vibration isolation support and vertical deformation of the vertical vibration isolation support can be realized, the horizontal deformation of the three-dimensional vibration isolation / shock support only occurs on the horizontal vibration isolation support, the vertical deformation of the three-dimensional vibration isolation / shock support only occurs on the vertical vibration isolation support, and the vibration (shock) isolation effect of the three-dimensional vibration (shock) isolation support is effectively improved.

Description

Technical field [0001] The present invention relates to a technical field of building structures, and in particular a horizontal two-dimensional vertical deformation decoupling isolator / isolators. Background technique [0002] Urban underground rail transit construction in my country's major cities in recent years gained rapid development, with its "low pollution, large volume, convenient" etc., has become an effective means to solve the problem of urban congestion. At this stage, the major cities are vigorously promoting the construction of urban underground rail transit, underground floor multi-purpose integrated transport hub. However, building structure subway lines getting closer distance, high-speed subway running, braking brakes, etc will lead to accelerated near the start of building construction vertical vibration and noise overrun problems, leading to the building near the subway lines or the superstructure building limited functionality, comfort structure can not mee...

[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
