[Technical field to which the device belongs]

 The present invention relates to a bearing ball base isolation base. INDUSTRIAL APPLICABILITY The present invention can be used for seismic isolation of buildings, machines, works, etc., and is installed to prevent the shaking of the upper structure from being transmitted in order to prevent damage from the earthquake. Available.

[0002]

[Prior art]

 In the event of an earthquake, the collapse of buildings and the fall of furniture and furniture often endanger the safety of internal residents. However, the current situation is that no good seismic isolation base has been proposed.

[0003] Today, any building such as a skyscraper or a high-rise condominium incorporating seismic isolation devices, vibration control devices, etc. is not provided with measures and devices against the thrust earthquake motion from directly underneath. Is very difficult except for small heavy items. The seismic isolation base for this bearing ball base is a mechanical seismic isolation base that does not use rubber for horizontal shaking during an earthquake. There are still many people who are concerned about the rubber's service life, material deterioration, fire resistance, heat resistance, etc. This bearing ball base seismic isolation base is a seismic isolation base that eliminates concerns like rubber.

[0004]

[Problems to be solved by the device]

 The present invention is a seismic isolation base that uses bearing balls and has a great effect. This aims to provide a more effective seismic isolation base.

[0005]

[Means for Solving the Problems]

 In the present invention, a pillar having a receiving surface for receiving a building in the upper part is provided at the upper and lower parts in the center, and the lower part of the pillar is supported by a bearing ball. Several ring seats are provided so as to overlap each other, and the ring seats are overlapped up to the protrusion of the side wall, and several leaf springs centering on the column are located above the ring seat from four corners. It relates to a bearing ball base isolation base provided for each two.

[0006]

[Embodiment of device]

 The following is a description with reference to the drawings. Reference numeral 1 is a side wall of the lower concave box, and is equipped with a protrusion 10 that absorbs horizontal movement, mounts a leaf spring, and receives the pulling movement of the upper building. Reference numeral 2 denotes a bottom portion of the lower concave portion, and transmits the upper load of the columnar body 4 of the upper convex portion and the bearing ball 9 to the support body. Reference numeral 3 denotes a receiving surface portion that integrally forms an upper portion of the columnar body 4, receives the load of the upper building, and transmits the load to the lower portion. Numeral 4 is a column, the upper part of which is the receiving surface part and the lower part is in contact with the bearing ball, which is required to transfer the load of the upper building to the lower part through the bearing ball 9 and to absorb the horizontal motion of the earthquake.

Reference numeral 5 denotes a bearing housing, which is integral with the columnar body 4. No. 6 is a structure in which several rings are attached to the upper part while sequentially overlapping parts. This is when a part of the upper part of the building is pulled out when the maximum horizontal swing range is reached. It is a steel ring seat to prevent pulling out of the, and is effective at any position of horizontal displacement.

Reference numeral 7 is a leaf spring, and there are several leaf springs, which retain a sufficient force against a lateral force such as an earthquake and a typhoon of a building, and maintain a horizontal stability in a normal state on the table of the bearing ball 9. . The leaf springs are arranged as shown in the figure, and two springs are projected from each of the four corners so that the force can be evenly held through the four hinges around the central pillar 4. . Reference numeral 8 is the hinge, and there are four hinges, each of which has two leaf springs. Reference numeral 9 is a bearing ball, which serves to minimize the friction between the building and the foundation when an earthquake occurs and to cut the movement of the earthquake.

Reference numeral 10 denotes a protrusion, which is integral with the side wall 1 and receives the pulling force of the ring seat 6 and is in contact with the uppermost ring seat. Reference numeral 11 denotes a corner member, which fixes the end of the leaf spring to the lower concave box to generate the effect of the leaf spring. Reference numeral 12 is a restraining portion, which is restrained from the upper side of the side wall 1 so that the force of the leaf spring can be sufficiently drawn. Numeral 13 is a bolt, which retains strength. Reference numeral 14 is a decompression hole in the bearing storage portion. Further, 15 is an internal lubricating oil.

Although the shaking of the earthquake is the same as the shaking of the lower concave portion, since the bearing ball 9 is laid on the pillar 4 of the upper convex portion supporting the building, the seismic motion is not transmitted to the upper building. Further, bearing balls are always laid on the lower part of the column 4 to withstand horizontal movement of the bottom part 2, and the bearing balls are simultaneously collected on the opposite side in the traveling direction. That is, it is the bearing storage part 5 for laying and collecting the bearing balls. In addition, oil is enclosed in the bottom to make the bearing rotate smoothly.

With respect to a lateral force such as a side wind at all times in a building, the leaf spring 7 having the end portions fixed to the four corners 11 has a hinge 8 to which the end portion of the leaf spring 7 is attached to the pillar body 4, Keep balance against force. The leaf springs 7 are arranged in such a manner that four right-handed coils are arranged in the upper stage and four left-handed coils are arranged in the lower stage so that a force such as a twist is not generated in the upper columnar body 4. A ring seat made of pull-out prevention steel was placed between the lower concave box and the column 4 in order to prevent lifting when the building stopped shaking. A rib is provided on the inner upper part of the ring seat 6 so that pulling can be counteracted without disturbing horizontal movement in all directions.

[0012]

[Advantage of the Invention] The present invention absorbs horizontal shaking during an earthquake, collapses the building, and the furniture and fixtures inside the building collapse, and above all, the safety of the occupants and the fire. It is extremely effective in preventing the next disaster.
