Abstract
Permanent magnet and electromagnet are installed in a kind of building earthquake-resistant apparatus, building and basis in-between, and when earthquake magnitude is less than 4 grades, permanent magnet is attracted the electromagnet not being powered, and building is fixed.When 5 grades or more earthquakes occur, electromagnet is powered, and the power for generating and repelling each other with permanent magnet is hanging by building, and the vibration energy on ground cannot pass to building, substantially reduce influence of the earthquake to building destruction.The electromagnet of the permanent magnet and the setting of building bottom side of the wall of damping mat and basic pit side wall setting is by adjusting suction, and limitation building is excessive to vacillate, and guide post, which limits building, topples over.At the end of earthquake, whether judges building in original position close to switch, if not the electromagnetic force by the electromagnet generation on basic pit side wall, building is adjusted to designated position.Then the electromagnet of control building lower end, electromagnetic force are adjusted gradually to zero.Corresponding electromagnet is sucked in the permanent magnet of basic pit bottom surface, and building is fixed.
Description
Technical field
The invention belongs to technical field of buildings, more particularly to a kind of building earthquake-resistant apparatus.
Technical background background
Earthquake-proof measure for building basis mainly considers the damping for the upper and lower and horizontal direction that earthquake generates, at present state
The interior implementation means to building basis are mainly reinforced concrete pipe pile.Some domestic famous buildings are also mixed using reinforcing bar
Solidifying soil pile pile is all the ground using piling bar as building such as Shanghai Jin Mao Tower and Shanghai world-wide trading center.This structure
Concrete tubular pile there is certain flexibility and high intensity.The flexibility on basis and high intensity, which are resistant to earthquake, to be had
Characteristic, flexibility can cut down energy caused by vibrations, and high intensity can bring the broken of structure to avoid vibrations to building
It is bad.
The Aseismic Design of building mainly considers several aspects：
1, the energy input of earthquake must be reduced, exactly reduces the energy transmission of earthquake to the greatest extent to building；
2, vibration isolation and energy-dissipating and shock-absorbing cut down the energy of earthquake by the damping of cushion, sliding, swing and suspention；
3, mitigate the weight of high-level structure, the mitigation of construction weight can make building when being shaken, when the deformation of building
Internal stress mitigates；
4, the anti-seismic ray of multiple tracks is designed, when can make prime precautions against earthquakes by destroying, subsequent emulation measure continues to undertake ground
The destruction of shake.
Concrete measure generally is that damping member is arranged on building, adds sliding bearing, adds vibration isolation rubber etc.
To eliminate the energy of earthquake.The phenomenon that reducing damage and resonance of the seismic energy to building occurs.Also it is exactly to design one
Kind of control device, allow this device by the acquisition to earthquake vibration signal after, the vibrations and the shake suffered by building of generation
Dynamic direction is on the contrary, offset the vibrations suffered by building.
Invention content
It is to provide a kind of building earthquake-resistant apparatus to the mesh of the present invention, it realizes building using the characteristic of electromagnet
Antidetonation.
As shown in Figure 1, the present invention is by installing electromagnet in the basic lower end of building, in the bottom surface of basic pit
Upper installing permanent magnet.Being fixedly connected between building and basis is the upper surface of permanent magnet and building lower end on the basis of leaning on
Section, which corresponds to, under the electromagnet of installing is attracted, and keeps the stabilization of building normal condition.Actuation between permanent magnet and electromagnet
Power is enough to overcome 4 grades of earthquakes once, because only that 5 grades or more just start to constitute building and destroy.When 5 grades or more of earthquake
When generation, set magnet spool is powered, and generates a magnetic field opposite with permanent magnet field, permanent magnet and electromagnet
Between generate mutually exclusive power.This repulsive force pushes building to separate a distance with basis, and at this moment basis is by earthquake shadow
Loud shaking force cannot pass to building, and building is not influenced by earthquake source.Building is just not easy to be destroyed.
In order to limit the horizontal drift of building, permanent magnet is buried on the side wall of basic pit, in building lower end
Electromagnet is embedded on side wall.Electromagnet is powered according to the case where drift and generates magnetic force, interacts, adjusts with the permanent magnet of surrounding
The position of whole building is in the range of restriction.
Since when building is hanging, smaller rolling power may be such that building topples over.On the bottom surface of basic pit
It is provided with guide post, the phenomenon that guide post passes through hole set on building, and limitation building is toppled over, guide post is built with passing through
Building between the hole of object has gap.In order to prevent since building is during drift, guide post is lived between face and building apertures
Impact force is generated when collision, and the second damping mat is installed between guide post and the hole of building.In building horizontal drift to one
When positioning is set, damping material absorbs the energy generated when building drift, reduces the shaking of building.So that building is provided with
Feature flexible.
Earthquake can be the vibrations for upper and lower directions from all directions.It is recessed in the lower section of building and basis
It is supported by the first damping mat between the upper section of hole bottom, the object constituted such as rubber material.First damping mat will cut down basis
The stress caused by the variation of vertical range between building.
It is installed on the side wall of basic pit close to switch, position detection ginseng is installed on the side wall of building lower end
According to object, switch and position detection object of reference are approached to correspondence.Close to switch when close to switch and position detection object of reference to corresponding to
Appliance contact switching.The purpose for the arrangement is that at the end of the earthquake, signal to allow electricity on basic pit side close to switch
Magnet generates magnetic force, building is adjusted to the relative position original with basis, the electromagnet of building lower end is slowly cut off
Power supply allows building to fall on the original position in basis.When electromagnet is attracted when being U-shaped by permanent magnet, closed magnetic circuit is formed, to week
The effect of magnetic influence enclosed is smaller, and suction also can be very big.
As shown in figure 3, for another conception.In the lower section fixing connection steel plate of building, installed on basic pit
There are spring, one steel plate for carrying multiple spherical pits of spring-loaded.Multiple steel balls are implanted into these spherical pits, Duo Geqiu
Upper end abut the connection of building lower part steel plate lower section.When seismic direction is horizontal direction, the steel plate on building area
The sliding of building level is driven, the energy that horizontal earthquake direction generates is cut down by the frictional force that rolls of steel ball.It is wherein set
Spring cut down building vertical tremor caused by energy.This spring should be the vibration-absorptive material with damping characteristic.
