Description

Technical field:

[0001] The invention relates to a building shock-isolation device with proper rigidity, damping and vertical bearing capacity, especially a three-dimensional shock-isolation device capable of simultaneously realizing building horizontal and vertical shock-isolation. Background technique:

[0002] In order to minimize the earthquake hazards of buildings, the concept of structural control has been proposed. The most feasible control devices or systems so far include three schemes: base isolation, damping energy dissipation and active control, among which base isolation is the most widely used. my country's new code for seismic design of buildings also incorporates foundation isolation technology, the purpose of which is to give full play to the advantages of this new technology. However, these control devices or systems currently only minimize or isolate horizontal seismic actions, and have little effect on vertical seismic actions. Due to the multi-dimensio...

Embodiment Construction

[0011] The present invention is described in detail below in conjunction with accompanying drawing and embodiment.

[0012] The three-dimensional seismic isolation device of the present invention is divided into upper and lower parts, wherein the lower part is the horizontal vibration isolator of the device, using conventional sandwich steel plate rubber pads 2, and its specifications can be selected according to the bearing capacity of the upper structure. The sandwich steel plate rubber pad 2 is connected to the lower structure through the bottom plate 1 fixed to the lower part, and the upper part is fixed to the connecting plate 3, and the upper part of the connecting plate 3 is the vertical vibration isolator of the device. The vibrator includes a sleeve 4 whose lower end is fixed to the connecting plate 3. The sleeve 4 is provided with a main disc spring group 7, an auxiliary disc spring group 10 and a viscoelastic damper 6. The main disc spring group 7 is located at At t...
