Description
Technical field
The present invention relates to a kind of pendulum-type steel ball damping structure earthquake isolation device, belong to Anti-seismic device of building field.
Background technology
Every the new method of the genus third generation antidetonation aspect that, cushion technique is approved jointly by builing industry and seismological department, it has obviously effect (theory analysis is thought can reduce seismic damage earthquake intensity grade) to resisting seismic damage, the external exploration practice Comparison of Gardening Activities carried out in this respect early, achieves many successful experiences.The following inexorable trend that application subtracts, seismic isolation technology is builing industry.
From subtracting, the structural principle of shock insulation product divides, and all kinds of cushioning products used in the world now can be divided three classes, respectively: laminated rubber damping bearing, pendulum-type damping shock absorber, frictional slip device.No matter now that series products does not all reach the degree be widely used, reason is that they all exist good and bad difference to a certain degree, does not all realize the function alleviating longitudinal earthquake active force, and Cost Problems.
Summary of the invention
The object of this invention is to provide that a kind of damping effect is obvious, cost is low, be easy to the pendulum-type steel ball damping structure earthquake isolation device promoted.
The object of the invention is to realize in the following manner:
The present invention includes movable tray, upper buckle closure, it is characterized in that: the top of movable tray is bowl-type groove, the bottom surface of bowl-type groove is circular flat, and sidewall is connected by two sections of taper surfaces to forming, angle between two sections of taper surfaces is obtuse angle, is inlaid with a circle magnet ring in edge, bottom surface; Upper buckle closure is lower convex truncated cone-shaped, be provided with a hemisphere to support at basifacial center, the end of upper buckle closure, upper buckle closure crouches in the groove of movable tray, the angle of the sidewall of upper buckle closure and two sections of sidewalls of movable tray groove is all in acute angle, between the sidewall of upper buckle closure and movable tray groove, be provided with a circle steel ball, steel ball is positioned at two sections of taper surface joining places of movable tray recess sidewall.
The upper edge of buckle closure is along being the downward flange of a circle on described.
Buckle closure is provided with reinforcing rib on described.
Advantage of the present invention is: damping effect obviously, have function, the cost of alleviating longitudinal earthquake active force low, be easy to popularization.

Fig. 1 is structural representation of the present invention;
Fig. 2 is the front view of movable tray;
Fig. 3 is Fig. 2 is top view;
Fig. 4 is the front view of upper buckle closure.
Detailed description of the invention
With reference to accompanying drawing, the present invention includes movable tray 1, upper buckle closure 2, the top of movable tray is bowl-type groove 1.1, the bottom surface of bowl-type groove is circular flat, sidewall 1.2 is connected by two sections of taper surfaces to forming, and the angle between two sections of taper surfaces is obtuse angle, is inlaid with a circle magnet ring 4 in edge, bottom surface; Upper buckle closure is lower convex truncated cone-shaped, be provided with a hemisphere at basifacial center, the end of upper buckle closure and support 2.1, upper buckle closure crouches in the groove of movable tray, the angle of the sidewall of upper buckle closure and two sections of sidewalls of movable tray groove is all in acute angle, between the sidewall of upper buckle closure and movable tray groove, be provided with a circle steel ball 3, steel ball is positioned at two sections of taper surface joining places of movable tray recess sidewall.In the upper edge of upper buckle closure along being the downward flange 2.2 of a circle, buckle closure is provided with reinforcing rib 2.3 on described.
During application, the present invention is arranged between the basis of building and support column, or between beam column.
It subtracts, shock insulation principle is as follows:
The effect of damper will reach the effect moved less on lower dynamic motionless or top exactly between floors.The combination of movable tray of the present invention and upper buckle closure, defines the inclusion body of three inclined-planes (two sections of taper surfaces of movable tray sidewall and the sidewall of upper buckle closure) around combination.Steel ball is placed in therebetween, no matter thataway rolls, all can produce two-way damping action, thus play the effect of damping.
To dissolving of lateral seismic active force:
Seismic wave is that wave rolling is transmitted, after ground receives seismic wave, it can drive movable tray to do lower swing motion obliquely along with the change of the Wave energy of seismic wave, and the motion of movable tray makes steel ball roll along ramp, the process one of rolling is that cushioning effect has dissolved geological process power, two is change the direction of motion to avoid power is delivered to upper buckle closure, achieves lower dynamic motionless object.
Dissolving longitudinal force:
Mainly be subject to longitudinal force the destruction of meizoseismal area building, this damping modes of the present invention more meets the actual conditions of earthquake active force, and damping effect is more obvious, higher than theoretical damping value.Damping device in the market just works to horizontal applied force.When building with fluctuation upwards lifting time, on in damper, buckle closure and movable tray form gap value and increase phenomenon, at this moment steel ball can under the adsorption of magnet, the gap of filling and increasing is rolled down along slope, on building is when falling, steel ball can be extruded gap by buckle closure, this process just forms damping buffering effect, thus plays the object dissolving longitudinal force.
Another peculiar function of damper of the present invention is that it can realize the rotation (upper rotation between buckle closure and freely movable bearing) of 360 degree, because seismic wave causing ground to occur sometimes after folding repeatedly, reflection, distortion changes this phenomenon, and at this moment damper has had this function just can avoid the destruction of this kind of seismic wave.
