Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing:

[0015] This embodiment is a three-dimensional vibration isolation device with a vertical vibration isolation function composed of a lead core laminated rubber horizontal vibration isolation support, a disc spring and a lead damper. The specific structure is as Figure 1 ~ Figure 3 As shown, it includes an outer guide rod 9, an outer sealing steel plate 11, an upper connecting plate 1, a lower connecting plate 2, a lead core laminated rubber bearing 13 and a disc spring 3. The upper connecting plate 1 is fixedly connected with the upper structure. The lower part of the lead-core laminated rubber support 13 is fixedly connected with the lower structure, and the upper part is fixedly connected with the lower connecting plate 2 through connecting bolts 12 . The disc spring 3 is placed between the upper connecting plate 1 and the lower connecting plate 2, and is limited left a...

Abstract

The invention relates to a vertical limit lead shear three-dimensional vibration isolation device which belongs to the structural vibration control and vibration control field. The invention designs the Belleville spring external guide part in the vertical vibration isolation device contacted with an external sealing steel plate to be a clamp plate lead shear damper; the three-dimensional vibration isolation device generates vertical vibration on the upper connecting plate under the excitation of the vertical loading; the vibration drives the lead block to have shearing deformation, so as to provide vertical damping force for the three-dimensional vibration isolation device. A vertical limiter is arranged between the external guide rod and the external sealing steel plate to control the rebound of the instantaneous Belleville spring; the vertical limiter also has the clamping plate effect, applies the horizontal pre-pressing force on the structure and avoids the extruding loss after the yield of the lead. The vertical limit lead shear three-dimensional vibration isolation device has the advantages of simple structure, stable performance, being applicable to the second vibration of the building induced by the traffic and any occasion that the three-dimensional vibration isolation device in the prior art is applicable to for isolating the ground vibration, reducing the power reaction of the structure and the device.

Description

technical field [0001] The invention relates to a vertical limit type lead shear three-dimensional vibration isolation device. The device is composed of a lead core laminated rubber support, a disc spring, a lead damper and a vertical limiter, and has a vertical limiter. It is mainly used for foundation vibration isolation of buildings such as houses and bridges, and can also be used for equipment vibration isolation. The invention belongs to the field of structure isolation control and vibration control. Background technique [0002] The seismic isolation device "isolates" the superstructure of the building from the foundation, changes the dynamic characteristics of the superstructure, and can greatly reduce the dynamic effect of the earthquake on the superstructure, thereby achieving the shock absorption effect of "overcoming rigidity with softness". There are many studies on vibration isolation devices for building foundations, but they mainly focus on the horizontal vib...
