Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, as shown in FIG. 1 , the lower plate 100 is a plate-shaped member that is composed of one of various shapes such as a circle or a square and is placed horizontally on the ground or the floor, and is opened upward to a certain depth. of the central groove 101 is formed at the top.

The central groove 101 is a groove into which the damping device 110 enters. The entrance is formed in a circular shape and the inner wall up to a certain depth is formed vertically, but the bottom surface constituting the lowermost end is formed to be inclined downward toward the center. The entire central groove 101 is configured to form a U-shape.

That is, the bottom surface of the central groove 101 has a structure in which the inclination is sharply formed from the center to the edge, and some sections constituting the center may be configured to be flat or to form a gentle inclination.

In addition, one or more friction members made of a rubber material may be provided at the lower end of the lower plate 100 , and the friction member configured in a flat plate shape is one formed to be opened downwardly at the lower end of the lower plate 100 . It is fitted into the above lower groove to form a strong frictional force with the ground or the bottom surface, and prevents the occurrence of scratches due to repeated friction between the bottom surface and the lower end of the lower plate 100 .

The damping device 110 is located inside the central groove 101 and is a device for attenuating vibration transmitted to the seismic isolation pedestal of the present invention, which is placed horizontally on the ground or floor due to earthquakes, etc. As shown in Fig. 2, a plurality of horizontal springs 115 connected to the inner wall side of the central groove 101 are connected to the side at regular intervals, so that despite the reciprocating movement of the lower plate 100 due to vibration, the original stationary It is designed to maintain the state as much as possible.

The plurality of horizontal springs 115 have one distal end connected to the inner wall side of the central groove 101 and the other distal end connected to the side surface of the damping device 110 to form upper and lower surfaces of the lower plate 100 . 3 or 4 springs that are horizontal to the and may be configured by connecting a plurality of tension springs having different elastic moduli to each other so as to effectively respond to both relatively small vibrations and relatively large vibrations.

In addition, as shown in Figure 2, the support portion 113 provided on the upper side of the damping device 110 is formed or provided on the lower portion of the object, etc. is configured to support the object, typically legs, pedestals As a component supporting a specific part referred to as a back, the lower end is supported by one or more vertical springs 112 , and an upwardly open fixing groove 111 is formed at the upper end thereof, which is referred to as a leg of an object, a pedestal, etc. Allow the parts to be inserted.

In this case, the inlet of the fixing groove 111 may be configured in one of various shapes, such as a circle or a square, to support a leg, a pedestal, etc. suitable for the shape.

In addition, the one or more vertical springs 112 supporting the support part 113 are preferably composed of a tensile spring having an appropriate elastic modulus so as to protect an object placed on the seismic isolation support from vibration in the vertical direction. Since specific parts referred to as legs, pedestals, etc. are not necessarily formed on objects placed on the seismic isolation stand of the present invention, in this case, the upper plate 130 directly supports the lower end of the object together with the support portion 113 . can do.

Accordingly, the height of the upper surface of the support part 113 and the height of the upper surface of the upper plate 130 are formed to be the same or the height of the upper surface of the support part 113 is formed to be higher than the height of the upper surface of the upper plate 130 Preferably, it is not necessarily limited to this form.

In addition, the hemispherical inlet groove 114 downwardly formed at the lower end of the damping device 110 is a space in which a part of the first ball member 120 is inserted, and the interior of the inlet groove 114 is an indentation groove. (114) It is desirable to form a structure capable of ensuring smooth rotation by minimizing the flow of the first ball member 120 in the interior and at the same time minimizing the contact surface with the first ball member 120.

That is, the internal structure of the internal groove 114 may be the same as or similar to the internal structure of a known ball mouth, but the depth of the internal groove 114 is greater than the diameter of the first ball member 120 . It is formed to have a short length, so that only a part of the first ball member 120 is inserted into the indentation groove 114 , and the other part protrudes downward of the damping device 110 .

Therefore, the first ball member 120 supports the damping device 110 and at the same time the damping device 110 in contact with the bottom surface of the lower plate 100 is in contact with the lower plate 100 despite the reciprocating movement of the lower plate 100 . and maintain the original still state as much as possible.

At this time, despite the reciprocating movement of the lower plate 100 , maintaining the original stopped state as much as possible does not necessarily mean that the damping device 110 is completely stopped. (110) is meant to include the same state as the stationary state and the state that vibrates within a certain range.

In addition, the first ball member 120 may be made of a material such as synthetic rubber or synthetic resin, but is made of a metal material such as iron, which is heavier than synthetic resin and has superior strength, so that the damping device 110 is It is preferable that the seismic isolation stand of the present invention be able to sufficiently support the weight of an object supported by it.

In addition, the first ball member 120 allows the vibration caused by friction with the bottom surface of the central groove 101 to be attenuated, and the damping device 110 moves along the bottom surface of the central groove 101 . It may be configured to be divided into an outer layer made of an elastic material, such as synthetic rubber, and an inner layer, made of a metal material, such as aluminum, so that the restoring force for returning to the original position can be improved when it rises to a certain height.

In addition, as shown in FIG. 3 , the vibration isolation stand with improved vibration resistance of hazardous substances handled according to the present invention prevents the flow of the damping device 110 by the first ball member 120 , which is usually spherical in shape. It is characterized in that a curved groove (102) having a semi-elliptical cross section is formed in the center of the central groove (101).

Specifically, the curved groove 102 is formed as a groove in which a portion of the first ball member 120 in contact with the bottom surface of the central groove 101 can fit or be inserted, and thus the attenuation In normal times, when external forces such as earthquakes do not act on the device 110, the position of the first ball member 120 may be fixed to the center of the bottom surface of the central groove 101, and when an external force occurs due to an earthquake, etc., the first ball The member 120 is configured to be detachable from the curved groove 102 .

In addition, as described above, the first ball member 120 may be entirely made of iron among metals, and since iron has a property of being attached to a magnetic material, the central portion of the central groove 101 is a magnetic material 103 having a magnetic force. ) to further improve the restoring force by the spring, and when the center of the central groove 101 in the state in which the curved groove 102 is formed is made of the magnetic body 103, the restoring force by the spring can be improved. In addition to the effect there is, an effect of preventing the flow of the damping device 110 by the first ball member 120 normally occurs additionally.

Therefore, compared to the conventional seismic isolating pedestal that can only form a restoring force corresponding to the elastic force of each spring, the seismic isolating pedestal of the present invention has the elastic force of each spring and gravity due to the inclined bottom surface and the magnetic body (103). It is a configuration in which the effect of forming a restoring force of a size corresponding to the resultant force added by the magnetic force is generated.

In addition, as an additional effect due to the above effect, the seismic isolating support of the present invention can exhibit the same or similar performance as the conventional seismic isolating support even in a miniaturized state compared to the conventional seismic isolating support.

In addition, when the central portion of the central groove 101 is composed of a magnetic material 103 having a magnetic force, the magnetic material 103 is manufactured separately from the lower plate 100 and then assembled to the lower plate ( 100), and as a method of locating the magnetic body 103 inside the central groove 101, a method of inserting and fastening the magnetic material from the upper side to the lower side of the central groove 101 or FIG. 4 (a) And a method of inserting and fastening upward from the lower end of the lower plate 100 as shown in FIG. 4(b) may be used.

Accordingly, a magnetic material groove capable of being inserted and fastened in a manner of fitting the magnetic material 103 may be formed in the center of the central groove 101, and the magnetic material may be inserted and fastened in the lower plate 100 from the bottom upward. An inner hole may be formed for

In addition, as shown in FIGS. 5A and 5B , the upper plate 130 has the same shape as the lower plate 100 , that is, one of various shapes such as a circle or a square. As a plate-shaped member horizontally placed on the upper end of the lower plate 100 , a fitting hole 131 penetrating the upper and lower ends is formed in the center so that the support portion 113 can be fitted.

Therefore, the upper plate 130 firmly supports the support part 113 in the lateral direction and at the same time guides the support part 113 so that it can be lifted only in the vertical direction, depending on the shape of the lower part of the object. It is possible to directly support the lower end of the object or the like together with the support portion 113 or directly support the lower end of the object or the like alone.

The plurality of lower grooves 132 are grooves of the same or similar shape as the inner groove 114 , and are configured so that each of the plurality of second ball members 140 can be entered, and the interior of the inner groove 114 . The structure minimizes the flow of the first ball member 120 and at the same time minimizes the contact surface with the first ball member 120 to ensure a smooth rotation of the first ball member 120, the lower groove 132 The internal structure of the second ball member 140 is preferably configured to minimize the flow of the second ball member 140 and at the same time minimize the contact surface with the second ball member 140 to ensure smooth rotation of the second ball member 140 . .

Accordingly, the second ball member 140 supports the upper plate 130 and at the same time the upper plate 130 positioned above the lower plate 100 is moved despite the reciprocating movement of the lower plate 100 . and maintain the original stationary state as much as possible.

At this time, the maximally maintaining the original stopped state of the upper plate 130 despite the reciprocating movement of the lower plate 100 does not necessarily mean that the upper plate 130 is completely stopped. (130) is meant to include the same state as the stationary state and the state that vibrates within a certain range.

In addition, the second ball member 140 may be made of a material such as synthetic rubber or synthetic resin, but is made of a metal material such as iron, which is heavier than synthetic resin and has superior strength, so that the upper plate 130 is It is desirable to be able to sufficiently support the weight of an object supported by the seismic isolation stand of the present invention, and the damping member 110 and the upper plate 130 are originally An embodiment of the present invention for maximally maintaining the stationary state of is shown in detail in Figs. 6 (a) to 6 (c).

In addition, the second ball member 140 has an outer layer made of an elastic material such as synthetic rubber and an inner layer made of a metal material such as aluminum so that vibration caused by friction with the upper surface of the upper plate 130 can be attenuated. It can be configured separately.

In addition, as a curved groove 102 having a semi-elliptical cross section is formed in the center of the central groove 101 , a portion of each of the plurality of second ball members 140 is also formed on the upper end of the lower plate 100 . An upper groove that can fit or enter may be formed. Accordingly, the position of the second ball member 140 is fixed at a designated position in normal times when external force due to earthquake, etc. does not act, and when external force due to earthquake, etc. occurs The second ball member 140 is configured to be separated from the upper groove formed at the upper end of the lower plate 100 .
