This new type of anti-seismic device adopts The structural system of steel frame-tube embedded in the tube, and electromagnetic dampers are installed between the tubes, they work together to isolate and delay vibration, buffer the impact of earthquakes on the building layer by layer, and protect the building well The internal structure is simple and economical.

Description

The novel earthquake-proof device

Technical field

The utility model relates to a kind of novel earthquake-proof device.

Background technology

Chinese ancient architecture adopts wooden construction more, its structure way has adopted flexible link technique, usings frame construction as the support of building, so can reach the effect of so-called " wall fall room do not collapse ", the connection of its flexibility, make again it have suitable elasticity and self-recovery ability to a certain degree.But the modern architecture floor is higher, mostly adopt the mode of construction of steel concrete, traditional shockproof structure can't meet the shockproof demand of modern architecture.

The utility model content

In order to address the above problem; the utility model proposes a kind of novel earthquake-proof device; adopt the structural system of steel frame-cylinder embedding cylinder; and between cylinder and cylinder, electromagnetic damper is set; their actings in conjunction are played shock insulation and are postponed the effect of vibrations; successively cushion the impact of earthquake on building, well protected the internal construction of building, simple economy.

The utility model solves the technical scheme that its technical problem adopts: a kind of novel earthquake-proof device comprises urceolus, middle cylinder, inner core, rubber base plate and electromagnetic damper; Described antishock device is nested with inner core, middle cylinder and urceolus from inside to outside successively, is filled with between cylindrical shell that some are flexible, the solid material of viscosity, plays shock insulation and postpones the effect of vibrations; The node junction of each cylindrical shell is equipped with electromagnetic damper; Top and the bottom of described inner core, middle cylinder and urceolus are respectively equipped with neoprene bearing.

The beneficial effects of the utility model are: a kind of novel earthquake-proof device; adopt the structural system of steel frame-cylinder embedding cylinder; and between cylinder and cylinder, electromagnetic damper is set; their actings in conjunction are played shock insulation and are postponed the effect of vibrations; successively cushion the impact of earthquake on building; well protected the internal construction of building, simple economy.

The accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described in further detail.

The structural representation that accompanying drawing 1 is a kind of novel earthquake-proof device.

The operating principle schematic diagram that accompanying drawing 2 is electromagnetic damper.

In figure, 1. urceolus, 2. in cylinder, 3. inner core, 4. electromagnetic damper, 5. neoprene bearing.

The specific embodiment

In the accompanying drawings, a kind of novel earthquake-proof device comprises urceolus 1, middle cylinder 2, inner core 3, rubber base plate 5 and electromagnetic damper 4; Described antishock device is nested with inner core 3, middle cylinder 2 and urceolus 1 from inside to outside successively, is filled with between cylindrical shell that some are flexible, the solid material of viscosity, plays shock insulation and postpones the effect of vibrations; The node junction of each cylindrical shell is equipped with electromagnetic damper 4; Top and the bottom of described inner core 3, middle cylinder 2 and urceolus 1 are respectively equipped with neoprene bearing 5.

Described neoprene bearing 5 can be replaced by other elastic support.

The circuit parallel connection of the above each electromagnetic damper 4, prevent that in earthquake, some dampers have damaged, and affects whole system.On the circuit of described electromagnetic damper 4, sensing switch is installed, circuit, at ordinary times in off-state, when inner structure quake gets up, is just connected circuit, can effectively prevent so in daily life because the harm that high-intensity magnetic field causes.

The operating principle of described electromagnetic damper 4 is: referring to accompanying drawing 2, when closed conductor and electromagnet generation relative motion, can produce electromagnetic resistance between the two, hinder its relative motion.In inner core 3 and urceolus 2 generation relative displacements, random up and down irregular vibration can occur due to the effect of earthquake in the node on inner core 3, the electromagnet of electromagnetic damper 4 Once you begin shakes in coil, excited electric current also to cushion simultaneously horizontal load pass to the intensity of internal construction, the huge architectural instantaneous energy that acts on that the electric current simultaneously excited can be very efficient produces earthquake promptly transform a part, for the electromagnetic damper 4 of middle cylinder 2 and urceolus 1, is also same reason.

Can between electromagnetic damper 4, add the fluent material of some viscosities on such basis, to reach better purpose of design, can also use spring to improve integrally-built stability, meet design requirement simultaneously.

Operating principle of the present utility model is: due to middle cylinder 2, inner core 3 and urceolus 1 use neoprene bearing 5 link with external structure, make urceolus 1 first shake with the earth under the unexpected effect of seismic (seismal simultaneously, but centering cylinder 2, because need to having enough distortion to produce enough power, elastomeric material could drive inner core 3 vibrations, so relative urceolus 1 vibrations of middle cylinder 2 can lag behind, that is to say middle cylinder 2, urceolus 1 vibrations are asynchronous, in like manner, cylinder 2 is also the same with inner core 3, so successively the benefit of buffering is well to have protected the internal construction of building structure, make it simple and economical.
