Embodiment Construction

[0012] The present embodiment will be further described below with reference to FIGS. 1-2 , and four-legged springs are used in the example.

[0013] As shown in FIG. 1 , this embodiment is a three-dimensional vibration isolation device composed of lead core laminated rubber bearings and four-leg disc springs 10 connected in series. The sealing steel plate 2 at the lower part of the lead core laminated rubber bearing is connected with the lower connecting plate 1 through the hexagonal bolt 4, and the lower connecting plate 1 is provided with bolt holes for connecting with the foundation. The sealing steel plate on the upper part of the lead core laminated rubber bearing is connected with the guide 8 through the hexagonal bolt 4 . An upper connecting plate 11 is arranged on the upper surface of the guide member 8 . The guide rod part of the guide 8 is arranged inside the sleeve part of the upper connecting plate 11, which is connected to the superstructure of the building. A ...

Abstract

The present invention relates to a horizontal shear type three-dimensional vibration isolation equipment, belonging to the field of structure vibration isolation and vibration control technology. It is characterized by that the upper surface and lower surface of laminated rubber support abutment in said equipment are respectively equipped with high-speed steel plate, the high-speed steel plate of lower surface is connected with lower connecting plate, said lower connecting plate is connected with foundation; the high-speed steel plate of upper surface is connected with guide component, on the guide component the upper connecting late is set, the guide rod portion of said guide component is set in the interior of sleeve portion of said upper connecting plate. On the lower surface of said sleeve portion and external surface of guide rod portion a quadrangular dish spring is set, on the undersurface of said quadrangular dish spring and on the upper surface of said guide component the recessed grooves are cut respectively, and said recessed grooves can be combined together and formed into a hollow cavity, in said hollow cavity the lead block can be injected. Said equipment can be used for isolating secondary vibration of building which is induced by rail traffic.

Description

technical field [0001] The invention relates to a horizontal lead-shear type three-dimensional vibration isolation device, which is mainly used for foundation vibration isolation of buildings such as houses and bridges, and belongs to the field of structure isolation control and vibration control. Background technique [0002] Rail traffic will induce secondary vibration of surrounding buildings, which will affect people's normal life. At present, the environmental vibration induced by rail transit mostly starts with the vibration source at home and abroad, but there are few studies on the vibration isolation device of the building foundation. Earthquake itself has multi-dimensional characteristics. At present, the three-dimensional base isolation device is mainly a series combination device of lead core laminated rubber bearing and thick rubber laminated rubber bearing or disc spring. The three-dimensional seismic isolation device "isolates" the superstructure of the build...
