Abstract

A quake isolator consists of an upper bearing plate and a lower bearing plate which laps over the upper one with the counter concave curves thereof opposite with each other, and a rolling ball which is set inside the room shaped by the upper and lower curves. The upper and lower bearing plates are located respectively among the base plate of a building or a machine and the bottom plate thereof and are jointed and fixed to the bases by steel angle. The column body of buildings or machine bodies can be placed above the base plate; the bottom plate is planted into ground foundation by screwing anchor bolts through the steel angle. While earthquake happens, the upper bearing plate, which moves horizontally as the rolling ball rolls and slides inside curve space between the upper and lower bearing plates, in accompany with the spring set on the base plate and the energy absorption pad set between the lower bearing plate and the bottom plate will work together to release horizontal and vertical vibration caused by earthquake so as to protect the building or machine.

200404941 V. Description of the invention (1) [Technical field to which the invention belongs] ··· The present invention relates to a vibration isolator, especially a shock isolator not located under a building. The bearing plate can cooperate with the rolling ball to reduce the horizontal and vertical seismic force generated by the seismic force, so as to exert the effect of shock absorption. [Previous technology]: The earthquake occurred due to the mutual pushing of the plates. Because Taiwan is located at the intersection of the Eurasian plate and the Philippine plate, earthquakes are frequent. Since earthquakes are unavoidable and cannot be predicted, only efforts must be made to prevent earthquakes. 'In order to reduce property damage and casualties. Applications and devices that have been around for a long time have spring dampers, shock absobers, and elastic pads. In view of this, a large number of additional rooms and support partitions are provided between the project, so that the horizontal vibration of the seismic ball or ball axis foundation can transmit the effect in the end, and it is beneficial to support the base insulation layer. According to the principle of designing the building, the patent of the building is disclosed in the zero-shear insulation layer at the time of the occurrence of the kinetic energy. On the ground, the principle of design power of the invention patent No. 1 9 8 7 3 9 of the insulation layer is used for the water retention machine. Consider the extremely low rolling friction thrust between the building and the ground and between the two adjacent supporting insulation layers, between the insulation layer and the ground and between the insulation layer and the foundation. The upper layer is attenuated layer by layer, so that the kinetic energy of the flat vibration reaches a state where it is insignificant. 200404941 V. Description of the invention (2), ^ ^ Zhenyi's focus is on zero shear force. Even if it can be isolated from ground vibrations ^ ^ ^, dreams, the effects of f ', but because you must use a lot of support = to "ball bearing" and other materials, in order to achieve the effect of reducing earthquakes, there are no checks and balances ^ Count ^ \ Existing costs The lack of expensive and bulky, but also used to respond to her + after the earthquake, the building is not easy to return to the original place, so it is not suitable for the shock absorption of factory machinery, there is no practical value in use. [Inventive content]: Che Xi ί hair ： Α 'Yuan is based on my years of experience in civil structure and geotechnical engineering, and is carefully researched through it.

Serving J force, Zhou Zhou earthquake force, Nengwuming, 1 / rj H. Here is the collection and conversion and early start recovery—one or two ^ Μα), a vibration isolator to reduce the vibration time, earthquake # year October, Production of the inventor—prototype proof The main purpose of the present invention is to provide a vibration isolator to change the conventional shock-proof device, so that it can achieve the same shock-absorbing effect with the least cost and the largest volume. . A secondary object of the present invention is to provide a vibration isolator, which allows the anti-vibration device to exert a full range of functions, and is not limited to the anti-vibration of buildings. 200404941 V. Description of the invention (3) In order to achieve the above-mentioned purpose, the upper and lower pressure-bearing plates described in this publication are superimposed on each other, and the balls are placed on the upper, lower, and lower pressure-bearing plates, respectively. The angle steel is fixed to the column or machine of the base plate or the bottom structure; the bottom plate of the bottom plate penetrates into the foundation; when the earthquake produces a curved space, it rolls and slides, and cooperates with the springs and pads provided on the base plate to eliminate the earthquake. The wisdom of the building or machine on the water substrate includes the upper and lower pressure plates and rolling balls; combined so that the upper and lower depressions of the curved surface oppose the curved surface, and the substrate or floor of the building or machine Between the boards. The base plate can be set to use the Miaoding screw inspection to pass through the angle steel and the time 'the horizontal movement of the pressure plate by the ball on the upper and lower pressure plates, and between the lower pressure plate and the bottom plate. It dissipates flat and vertical vibration forces to achieve protection. According to the invention, the invention has the following advantages in design: 1. Because the upper and lower pressure plates of the invention are provided with corresponding upper and lower surfaces and curved surfaces Depth and roughness are in accordance with the principle of the roller curve meter, so when the ball rolls on the surface 1, the vibration force level #, 4 == can be eliminated in any direction for the weight, and the energy dissipation speed is fast, The damping efficiency is high, and the shaking is almost stopped immediately. Environmental protection at the time of bearing physics Because the contact surfaces of the upper and lower bearing houses of the present invention can also be fitted into the corresponding friction rings, the upper friction rings can encounter the gravity daylight generated by the spring when encountering long thick ^ layers ^ moderate earthquakes Maintain a large coefficient of friction, so the present invention and the lower friction

Page 7 5. Description of the invention (4) The generation of vibration. 3. Another practical structure of the present invention is also a two-pressure bearing plate and a middle eight type, which belongs to a single pendulum type shock absorber. When the number of basic balls is enough, two balls are lost. As long as the load capacity is not very large, the contact curve between the intermediate support plate and the sphere can be higher than the clearance between the two pressure plates, so as to prevent the sphere from escaping. The avoidance = contour is changed to the tangent slope is discontinuity. The degeneration damping and the additional compound Liuyi are like being delayed, inverted, and have a dissipative effect. They are most suitable for: single pendulum movement to achieve small-scale vibration. —Floor and machine to cope with small vibration or small scale 4. As the present invention only needs to use small to achieve the effect of anti-vibration, in addition to d: constructing women's clothing, dry enclosures that can be used in addition to buildings are also used in factory machinery on. 5. Since the present invention can also place an energy dissipating cymbal between the lower pressure plate and the base, for some low-energy vibrations or wind, when the load is shaken by adding it to the load, the energy dissipating pad is used to shake the load. Can reduce most of the shaking and reduce the effect of shaking.
