Description
Technical field
This utility model is related to spatial mesh structure, and in particular to a kind of new spatial network with damping function
Ball node device.
Background technology
China is located in two main earthquake zones-between Eurasian earthquake zone and circum-Pacific seismic belt, be to be subjected in the world
One of to earthquake damage country the most serious.In history, Yangtze River Delta and the Delta of the Pearl River once repeatedly occurred 6 grades with
On macroseism, in Beijing-Tianjin Bohai Rim, over nearly 300 years, just there is the violent earthquake of more than 7 grades averagely per 44 years.With
The quickening of urbanization process, substantial amounts of national wealth is quickly to city and group of cities area concentration.And China 1/3rd with
On the built or group of cities planned to build be located at it may happen that the area of more than 7 grades violent earthquakes.City inner structure, equipment and collection
The destruction of historical relic and the economic loss and casualties that cause will cause huge impact to national security and social stability.Earthquake
It is that, as earth formation is in complicated stress state, with being continually changing for the earth's crust, the effect of crustal stress exceedes somewhere rock
During the ultimate strength of layer, rock stratum will occur unexpected fracture and the changing of the relative positions, so as to cause vibrations, and be passed in the form of elastic wave
Earth's surface, causes the object with certain mass of adjacent ground surface to produce inertia force, when this inertia of opposing that object has in itself
When the shock resistance of effect is not enough, there is destruction in object.And the natural vibration period of the predominant period and object for working as earthquake motion relatively connects
When near, the destruction of object just will be more serious.And by certain earthquake isolating equipment being arranged to object can significantly change object
Natural vibration period, so as to avoid the predominant period of earthquake, so as to significantly reduce acting on the inertia force of object, reduce object on ground
Destruction under shake effect, increases safety of the object under earthquake.
Traditional seismic isolation technology that subtracts is generally divided into two big class：One class be by the setting of earthquake isolating equipment come extending structure from
Shake the cycle, reduce the earthquake response of superstructure；The another kind of device for being to arrange by the junction on structure with basis power consumption,
Energy input of the earthquake to structure is consumed, so as to reduce the seismic energy being input in structure, the destruction of geological process is reduced.Mesh
It is front both subtract seismic isolation technology and achieve preferably application.For space structure, as which accepts complicated mechanism, on ground
During shake, the participation of three orthogonal directions can not be ignored, therefore the application of shock insulation is extremely difficult.However, it is possible to pass through to increase
Plus the mode of space structure damping improves the energy dissipation capacity of space structure, so as to increase the shock resistance of space structure.
The content of the invention
To solve the above-mentioned problems in the prior art, this utility model have developed a kind of simple installation and by increasing
The device damped to increase the energy dissipation capacity of space structure of rod member and hollow steel ball connecting node.By following technical scheme reality
It is existing：
A kind of new spatial network ball node device with damping function, including bolted node sphere and coupled bar
Part, the device also include the antivibrator in the bolted node sphere, and the antivibrator includes oil cylinder, oil cylinder top cover and oil cylinder top cover
The mild steel of connection, piston and piston rod, the other end of the mild steel connect the piston, and one end connection of the piston rod is described
Piston, the other end connect the rod member, and the mild steel and piston are placed in the oil cylinder, and the lower end of the oil cylinder and the section
Installing hole on penalty kick is connected.
Preferably, the piston is provided with aperture, when piston is moved, viscous damping liquid may pass through aperture.
Preferably, the oil cylinder lower end is threadedly coupled with the installing hole on the bolted node sphere.
Preferably, the piston rod is threadedly coupled with the rod member.
Preferably, the bolted node sphere is connected with two or more rod member, and each rod member is respectively connected with the antivibrator.
During non-earthquake state, rod member internal force is undertaken by mild steel, in poised state；Under 3-D seismics effect, structure occurs
Deformation, in vibration, the stress of rod member changes, and mild steel occurs compression and tension and compression reciprocal transformation, and oil cylinder piston is moved,
Viscous oil produces damping effect after the aperture on piston, and the deformation of mild steel itself also has damping effect.Therefore increased
The overall damping of structure, so as to reduce the dynamic response of structure, improves the shock resistance of structure.
Compared with prior art, had the advantage that using this utility model of above-mentioned technical proposal：Utilization space
With this real current situation of hollow ball node in structure, ball node inner space is rationally utilized, antivibrator is installed inside which, it is soft
Steel is used as transmission internal force during normal work, and antivibrator only works when structure occurs and vibrates.Can accomplish in construction
Assembling is arrived after the completion of factory process, and antivibrator is inside ball, easy construction, neat and artistic can be accomplished, and damped
Device can adopt other various ways, including viscous damper, metal damper etc..
