Description

Seismic isolator {VIBRATION ISLOATION APPARATUS}

The present invention relates to a seismic isolating device, and more particularly, to a seismic isolating device capable of protecting facilities and people in a building by insulating vibration applied to a building from the ground when an earthquake occurs.

The term "seismic isolation" generally refers to the overall technology for separating the entire building structure from the ground or for separating a specific part inside the building structure from the building structure.

This seismic isolating means that even if the ground or the building structure vibrates greatly when an earthquake occurs, the building structure or a specific part of the building that is separated from the ground vibrates relatively little, so that the building structure or equipment installed on a specific part of the building is not vibrated. It means protecting against earthquakes.

On the other hand, "seismic resistance" means that even if structures such as buildings, bridges, etc. vibrate greatly due to an earthquake, the structure itself is designed to be sturdy so that the structure does not collapse, or a means is provided to absorb vibrations in the structure.

As invented from the above point of view, there may be mentioned things such as "An earthquake prevention system for buildings" (hereinafter referred to as prior art) in Korean Patent Application Publication No. 10-2007-0091384.

The prior art is to dig into the ground and drive a concrete pile, install an H beam die on the concrete pile, attach a female hinge at the edge of the H beam die, make an H beam die, and fix the drast wheel under the die to support the weight of the building, and then pipe the spring again. It is a structure in which the spring is slightly elastic by inserting it inside, fixing it at the bottom of the H-beam die, and fixing it to the die of the concrete pile.

However, in the prior art, since the concrete pile is directly inserted into the ground and fixed, it is difficult to expect the seismic vibration between the building and the ground to be reliably separated and insulated.

Therefore, it is urgent to develop a device that can protect facilities and people in the building by insulating vibration applied to the building from the ground when an earthquake occurs with a relatively simple structure.

For reference, FIG. 1 is a perspective conceptual diagram showing a structure in which a seismic isolator according to an embodiment of the present invention is installed between a building and the ground.

Further, FIG. 2 is a side cross-sectional conceptual view showing the overall structure of a seismic isolator according to an embodiment of the present invention, as shown along line II-II of FIG. 1.

In addition, FIG. 3 is a partial perspective conceptual diagram showing a coupling structure between the ball 210 and the guide panel 220 of the second unit 200, which is a main part of the seismic isolator according to an embodiment of the present invention.

In addition, FIG. 4 is a plan view showing the arrangement structure of the line support part 320 of the third unit 300, which is a main part of the seismic isolator according to an embodiment of the present invention, as viewed from the point IV of FIG. 2.

In the present invention, as shown, the first unit 100 is disposed between the building 400 and the ground 500, and the second unit 200 is between the steel plates 110 and 120 of the first unit 100. And the third unit 300 is formed between the outer surface of the first unit 100 and the building 400 and the ground 500, thereby preventing the seismic vibration between the building 400 and the ground 500 as a whole. It can be seen that it is an insulated structure.

Therefore, the seismic isolator according to the present invention is disposed between the building 400 and the ground 500 to insulate the seismic vibration generated from the ground 500 from being transmitted toward the building 400 and at the same time absorb the seismic vibration. Or, it will play a role of dispersing.

First, the first unit 100 includes a plurality of steel plates 110 and 120 spaced apart from each other so as to be stacked in a vertical direction between the building 400 and the ground 500 in order to maintain structural strength, and a plurality of steel plates ( It includes a wire mesh 130 surrounding the edges of each of the 110 and 120.

In addition, the second unit 200 is disposed between the plurality of steel plates 110 and 120 to distribute or absorb the fluctuations in the vertical direction and the left and right directions including shear stress applied to the first unit 100 due to earthquake vibration. It is to include a plurality of bearings (210).

In addition, the third unit 300 wraps the outer surface of the first unit 100 or connects both ends between the building 400 and the ground 500, thereby allowing shape deformation against earthquake vibration.

It goes without saying that the present invention can be applied to the above-described embodiments, and can also be applied to the following various embodiments.

First, the plurality of iron plates 110 and 120 may include a first iron plate 110 and a second iron plate 120 according to their thickness.

The first steel plate 110 is disposed in contact with the floor surface or the ground 500 of the building 400 and has a first thickness, and the second steel plate 120 is the above-described first steel plate ( 110) are arranged in a plurality of upper and lower layers, spaced apart from each other, and have a second thickness less than or equal to the first thickness.

The first thickness of the first steel plate 110 will be about 16 millimeters thick in an industrial field, and the first steel plate 110 is provided to perform a role for maintaining structural strength.

In contrast, the second steel plate 120 has a relatively thin thickness compared to the first steel plate 110 while allowing shape deformation and elastic deformation, thereby absorbing vertical vibration applied from the ground 500 to the building 400 It is also prepared to perform the role of a leaf spring.

For reference, when the first steel plate 110 is in contact with the reinforced concrete of the building 400 when it is actually constructed at a construction site, more specifically, when it is fixed by a method such as welding, deformation should not occur, and hundreds of thousands of tons Since the building 400 must have a material and thickness strong enough to support the weight, it is preferable to be made of a material having a certain level of strength and thickness.

Therefore, it goes without saying that the number and thickness of the second iron plate 120 can be appropriately modified in consideration of the structure of the top and bottom arrangement of the first iron plate 110 and the size and volume of the building 400.

The first steel plate 110 is not particularly illustrated, but it is of course possible to design and modify the first steel plate 110 to be arranged in a grid shape when viewed from the top so as to improve structural strength and load support and dispersion capabilities.

In addition, the wire mesh 130 may be manufactured to be formed in a cylindrical or square column shape so as to surround the edges of each of the plurality of iron plates 110 and 120.

The wire mesh 130 absorbs or disperses the vibrations in the vertical and horizontal directions by a mesh structure formed over the surface, so that a plurality of second iron plates 120 play a role of maintaining when a multi-layered structure is secondarily held. It was prepared for.

First of all, when the wire mesh 130 is out of the allowable shear stress and the torsion range due to the seismic vibration in the vertical and horizontal directions due to a very strong earthquake, the building 400 collapses due to the destruction of the seismic isolator. There is a possibility that it may arise, but it was prepared to dispel such concerns.

Specifically, the wire mesh 130 acts as a stopper for a very large earthquake that is out of the torsion range due to the permissible shear stress and seismic vibration in the vertical and horizontal directions. By absorbing or dispersing the seismic vibration of the wire mesh 130, the second iron plates 120 and the second units 200, which will be described later, are wrapped around and protected from out of the torsion range.

In addition, although the steel plates 110 and 120 and the wire mesh 130 according to the present invention are shown to be formed in a rectangular column shape as a whole in the drawing (refer to FIG. 1), it is not necessarily limited to this structure, and depending on the manufacturing and installation environment It goes without saying that the first unit 100 may be installed as a whole to be formed in a polygonal column or cylindrical shape.

Meanwhile, the second unit 200 may recognize that the ball 210 has a structure in which the ball 210 is accommodated in the support hole 221 of the guide panel 220 and is prevented from being separated from the guide partition 230.

In addition, the guide partition 230 extends along the edge of the support hole 221 and is bent upward or downward, so that each of the balls 210 is prevented from being separated from the support hole 221. It is prepared.

Accordingly, the edge of the guide panel 220 may be supported by the inner surface of the wire mesh 130.

On the other hand, the above-described guide partition 230, as shown in Figure 3, along the edge of the support hole 221 toward the center of the support hole 221 is formed to extend radially disposed extending piece 231 of the first width, An embodiment of a structure including a contact piece 232 extending from an end portion of the extension piece 231 and having a second width greater than the first width may be applied.

Therefore, the extension piece 231 is simultaneously bent upward and downward with respect to the edge of the support hole 221 as shown in FIG. 3(b), and a pair of guide panels 220 are butted up and down, and the upper side The extension pieces 231 provided on the guide panel 220 of the are bent upward and at the same time, the extension pieces 231 provided on the guide panel 220 of the lower side are bent downward.

By doing so, a guide partition 230 is formed that simultaneously supports the outer surface of the ball 210 in the vertical direction by the extension piece 231 and the contact piece 232 (refer to the enlarged portion on the right side of FIG. 2), and the ball 210 A structure that prevents departure can be provided so that the place where) is initially placed can be maintained as it is.

On the other hand, the third unit 300 is disposed so as to surround the entire wire mesh 130 forming the outer surface of the first unit 100 in the shape of a circular column or a square column to allow shape deformation and elastic deformation ( 310), and an upper end portion 321 fixed to the bottom of the building 400, and a lower end portion 322 fixed to the ground 500, and may include a line support portion 320 that allows shape deformation and elastic deformation. .

These seismic isolating pillars maintain all parts necessary for vibration insulation, such as internal steel plates 110 and 120 and balls 210, together with the above-described wire mesh 130, while seismic vibration is directly applied to the building 400. It is to provide a triple safety device that absorbs or disperses from the surface so that it is not transmitted.

On the other hand, the line support part 320 includes a spring 323 that connects between the fixed upper part 321 and the lower part 322 and is telescopically mounted, and the spring 323 is a wire mesh having a shape of a circular column or a square column. It may be disposed to be spaced apart for each of the outer surface of (130).
