在前述習知地震隔離裝置中，作為地震隔離元件之彎 曲元件放置成與振動方向平行，以獲得最高之能量吸收效 15 率。因此，假設能量由所有方向進入該地震隔離裝置，則 希望即使該能量由某特殊方向進入時，亦可得到一相等之 地震隔離效能。因此，在設計一地震隔離元件時，必須作 非常詳細之評估。此外，由於前述評估，對該地震隔離元 件之形狀會有特殊之限制，且該地震隔離元件必須依據這 20

Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a seismic isolation device for a structure, a method for providing the seismic isolation device, and a seismic isolation element. The present invention claims priority to Japanese Patent Application No. 2007-279148, filed on Jan. 26,,,,,,,, BACKGROUND OF THE INVENTION In the past, in structures such as buildings, bridges, elevated roads, and elevated rails, there has been a place such as a building skeleton such as a structure and a lower portion such as a foundation of a building. The seismic isolation device between them thereby buffering the vibration of the upper portion relative to the lower portion of the 15 when exposed to a large amount of energy, such as when an earthquake occurs. For example, the following Patent Documents 1 to 3 have disclosed a seismic isolation device in which an isolator and a buffer mechanism are combined between the upper portion and the lower portion. In the foregoing seismic isolation device, an isolator made of a plurality of alternately stacked metal plates and a plurality of plate-like elastic bodies is disposed between the upper portion and the lower portion 20 and fixed to both of them. The upper portion is supported by the lower portion through the isolator, and a buffer mechanism has a plurality of seismic isolation members (bending members) made of an elastic plastic material. The plurality of seismic isolation elements are regularly placed adjacent to the isolator (eg, in a radial manner), and the seismic isolation elements are independently fixed, in particular, one end of which is fixed to the upper portion and the other 5 200920965 One end is fixed to the lower portion. In the buffer mechanism, when a large amount of energy acts on a structure, and thus the upper portion vibrates in a horizontal direction relative to the lower portion, for example, when an earthquake occurs, the seismic isolation element is plastically deformed to absorb the seismic energy. In other words, the energy entering the upper portion is absorbed, 5 making the seismic isolation elements plastically deformable. Patent Document 1: Japanese Patent No. 3533110 Patent Document 2: Japanese Patent No. 3,354,004 Patent Document 3: Japanese Unexamined Patent Application Publication No. Publication No. No. No. No. No. No. No. No. Problem In the aforementioned conventional seismic isolation device, the bending element as the seismic isolation element is placed in parallel with the vibration direction to obtain the highest energy absorption efficiency. Therefore, assuming that energy enters the seismic isolation device from all directions, it is desirable to obtain an equal seismic isolation performance even when the energy enters from a particular direction. Therefore, when designing a seismic isolation component, a very detailed assessment must be made. Moreover, due to the foregoing evaluation, the shape of the seismic isolation element is particularly limited, and the seismic isolation element must be accurately fabricated in accordance with these 20 limits to provide a predetermined shape. Therefore, in the conventional seismic isolation device, a large amount of labor is required both in the design phase and in the manufacturing phase, resulting in an increase in manufacturing cost. The present invention has been made in view of the foregoing circumstances, and an object thereof is to provide a seismic isolation device for a structure having a high production efficiency at a design stage and a manufacturing stage, and a low manufacturing cost of 200920965, A method of apparatus and a seismic isolation element. In order to achieve the foregoing objects, the present invention provides a seismic isolation device for buffering vibrations above an upper portion of a structure relative to a lower portion of the structure. The 5 seismic isolation device has a plurality of U-shaped seismic isolation elements, a first bonding plate, and a second bonding plate. One end of the seismic isolation element is fixed to the first bonding plate, and the other end of the seismic isolation element is fixed to the second bonding plate. Some of the plurality of seismic isolation elements are disposed between the first bonding plate and the second bonding plate in a predetermined direction, and the other plurality of seismic isolation elements are disposed in the first direction opposite to the predetermined direction. Between the bonding plate and the second bonding plate. In the seismic isolation device of the present invention, both ends of the seismic isolation element may be respectively fixed to the first bonding plate and the second bonding plate by bolts. Each bolt may be disposed at a portion of the seismic isolation element fixed to the first 15 bonding plate and a portion of the seismic isolation component fixed to the second bonding plate, or Most of them are set at various parts. For example, three bolts can be used for fixing, and each bolt is preferably placed at the apex of a triangle. In addition, both ends of the seismic isolation element may be respectively soldered to the first bonding board and the second bonding board. In the seismic isolation device of the present invention, a plurality of recesses are respectively formed on the first bonding plate and the second bonding plate, and one or the other end of the seismic isolation element is embedded in the concave portions, and then the seismic isolation element is Both ends can be respectively embedded and fixed to the first bonding board and the second bonding board. The seismic isolation device of the present invention may include an isolator, and the isolator 7 200920965 "has a metal plate and a plate-like elastic body that are stacked in a wrong manner, and the separator is preferably placed between the upper portion and the lower portion. The present invention provides a method for providing a seismic isolation device, and the seismic isolation device has a first bonding plate that can be fixed to a lower portion of the structural body, and can be fixed to an upper portion of the structural body opposite to the lower portion. a second bonding plate, and a plurality of the first bonding plate and the second bonding plate are respectively fixed to the first bonding plate and the second bonding plate, and are opposite to a direction of the 骸 and a direction opposite to the predetermined direction of the 5 10 Placed on the lower portion and the upper portion. The method of setting includes a step of positioning the seismic isolation device on the lower portion such that the earthquake is positioned from the upper portion to the lower predetermined vibration direction of the lower portion, a step of fixing the seismic isolation device to the lower portion, a step of disposing the upper portion on the seismic isolation, and a step of fixing the seismic isolation device to the upper portion. The present invention provides a ground Seismic isolation element, the seismic isolation element is placed between an upper portion and a lower portion to thereby dampen the vibration of the upper portion to the lower portion in the forward direction and the lower portion by its own plastic deformation. The seismic isolation element is formed as a U-shaped and placed between the upper portion and the lower portion in a pre-discriminating direction of the county, and which is end-shaped to the lower portion and whose other end is fixed to the upper portion. In the present invention, for example, when When a large amount of energy such as an earthquake acts on a structure including an upper 4 and a lower portion, thereby causing the upper portion to vibrate in a direction relative to the lower portion of the seismic isolation element, the seismic isolation elements are plastically deformed and - The end moves away from the other end, thereby dissipating the energy into the upper portion. Therefore, the vibration of the upper portion is buffered. 20 200920965 According to the present invention, a direction of vibration entry is preset, and the seismic isolation elements are placed. The positioning can be positioned along the set direction, so that the vibration of the upper portion is effectively buffered in the set direction. In other words, in the present invention, since the energy is not assumed Directional entry, but assumes that 5 energy enters only in a particular direction, so unlike a conventional case, it is not necessary to make a detailed assessment of the design of such seismic isolation elements. Furthermore, since the shape of the seismic isolation elements is not given Special limitations, so it is not necessary to increase the cutting accuracy of the seismic isolation elements to a conventional seismic isolation element;: degree. 10 Effect of the invention The production efficiency of the seismic isolation device of the present invention can be both at the design stage and at the manufacturing stage.

Further, although not shown, the 10 studs 31 are joined to the reinforcing steel disposed in the upper portion A, whereby the seismic isolation device 1 can be more strongly coupled to the upper portion A. As previously mentioned, the seismic isolation device 1 is disposed between the upper portion A and the lower portion A. When a large amount of energy such as an earthquake acts on the structure including the upper portion A and the lower portion B, and thereby the upper portion A faces the lower portion B toward the direction of the seismic isolation element 10 such as the 15 (by the second figure) When the two-way (positive/negative) direction indicated by the double arrow X vibrates, the seismic isolation elements 10 are plastically deformed to move toward the one end 11 away from the other end 12, thereby consuming energy entering the upper portion A. Therefore, the vibration of the upper portion A can be buffered. According to the seismic isolation device 1, the direction of vibration entry is preset, 20 and the seismic isolation elements 10 are placed along the set direction (bidirectional (positive/negative) indicated by the double arrow X in Fig. 2 Positioning), whereby the vibration of the upper portion A generated in the set direction can be effectively buffered. In other words, since it is not assumed that energy enters the upper portion A from all directions, but that energy is only entered by a specific direction, unlike a conventional case, it is not necessary to perform detailed evaluation when designing the ground isolation component ίο. The shape of the spacer element 10 imparts a special limit to the cutting accuracy of the spacer element 10 to -. Moreover, since there is no such seismic system, it is not necessary to increase the extent of such seismic-known seismic isolation elements. The production efficiency of the morning isolation device L can be increased in both the design stage and the in-process kP white section, and thus the manufacturing cost of the seismic isolation device is low. Fig. 4 shows an earthquake which is disposed on the seismic isolation device 1 of the present invention

Hole 54. The seismic isolation element 50 is fixed to the first bonding plate 20 by a bolt 40, and is similarly fixed to the second bonding plate 30 by a bolt 40. In the foregoing seismic isolation element 50, if a bolt 40 is used as the fixing means for the bonding plates 20 and 30, the bonding plates 20 and 30 are fixed at a lower strength. However, when a plurality of vibrations act on the seismic isolation device 1 in a direction different from the predetermined direction, there is an advantage in that the bolts are relatively loose. Moreover, the seismic isolation devices 1 are constructed of a smaller number of components, thereby reducing manufacturing costs. Figure 5 shows a second exemplary variation of a seismic isolation element disposed on the seismic isolation device of the present invention. A seismic isolation element 60 as a second exemplary variation has three through-holes 63' for allowing the tamper 40 to pass through a bracket portion 61 disposed at one end and located at three vertices of a triangle. The bolt 40 is passed through three through holes 64 of the bracket portion 62 14 200920965 disposed at the other end. The seismic isolation element 60 is secured to the first bond plate 20 by three bolts 40 and is similarly secured to the second bond plate 30 by three bolts 40. In the aforementioned seismic isolation element 60, the number of bolts 40 is increased to serve as a fixing means for the bonding plates 20 and 30, whereby the bonding plates 20 and 30 can be more firmly fixed. In addition, the bolts 40 are arranged to be positioned at the apex of a triangle, so that when vibrating in a direction other than the set direction acts on the seismic isolation device 1, the advantage is that compared to the combination When the plates are fixed by two bolts, they are not loosened, and the number of the bolts 10 is increased to reduce the size of each bolt. Figure 6 shows a third exemplary variation of the seismic isolation element disposed on the seismic isolation device 1. At the bracket portions 71 and 72 provided at both ends of the seismic isolation member 70 as the third exemplary modification, a through hole for allowing a bolt to pass is not formed. Then, one of the bracket portions, that is, the bracket portion 71, is fixed to the first coupling plate 20 by welding. Further, although not shown, the other bracket portion 72 is fixed to the second coupling plate I 30 by welding. A plurality of solder beads 73 are formed between the bracket portion 71 (or the bracket portion 72) and the first coupling plate 20 (or the second coupling plate 30). - In the aforementioned seismic isolation element 70, the junction plates 20 and 30 can be more firmly fixed. Further, the seismic isolation device 1 is composed of a small number of components, so that the manufacturing cost can be reduced. Figure 7 is a first exemplary variation of a method for securing the seismic isolation element 10 to the first bonding plate 20 (second bonding plate 30) in the seismic isolation device 1. In the first exemplary variation, a counterbore (corresponding to the recess of the present invention) 22 for fitting a bracket portion 13 of the 200920965 at one end 11 of the seismic isolator element 10 is formed to fix the The side of the first bonding plate 20 of the seismic isolation element 10 is on the side. Next, the seismic isolation element 10 is embedded in the counterbore 22, and a bolt 40 is passed through a through hole 15 formed in the bracket portion 13 5 and fixed to the first bonding plate 20 through the bolt 40. . In addition, although not shown, the bracket portion 14 disposed on the other end of the seismic isolation element 10 is also embedded in a counterbore formed in the second bonding plate 30, and the bolt 40 can be formed in the bracket through The through hole 16 in the portion 14 is fixed to the second bonding plate 30 through the bolt 40. In the foregoing seismic isolation device 1, a bracket portion 13 of the seismic isolation element 10 is embedded in a counterbore 22 formed in the first coupling plate 20, and then the two are fixed to each other, so that it can be stronger The seismic isolation element 10 is fixed to the first bonding plate 20. Similarly, the other bracket portion 14 of the seismic isolation element 10 is embedded in a countersunk hole formed in the second bonding plate 30, and then the two are fixed to each other, so that the earthquake can be stronger The spacer element 10 is fixed to the second bonding board 30. In addition, a portion of the force generated on the seismic isolation element 10 can be directly transmitted to the first bonding plate 20 by the bearing pressure acting on the contact surface between the bracket portion and the countersink, thereby reducing The force held by the bolt 40. Thus, 20 can reduce the diameter of the bolt 40 or reduce the number of such bolts 40. Figure 8 is a perspective view showing a second exemplary variation of a method for fixing the seismic isolation element 10 to the first bonding plate 20 (or the second bonding plate 30) in the seismic isolation device 1. In the second exemplary modification, a U-shaped auxiliary member 23 is fixed by welding or other means to the side of the first bonding plate 20 to which the ground isolation member 1 is attached. A recess 24 corresponding to the counterbore 22 of the first exemplary variation is formed by the side of the inner side of the auxiliary member 23 and the side of the first coupling plate 20, and is exposed to the side of the inner side of the auxiliary member 23. Surrounded. Next, a bracket portion 13 of the seismic isolation element 10 is embedded in the recess 24 and fixed to the first bonding plate 20 through the bolt 40. In addition, although not shown, the bracket portion 14 disposed at the other end 12 of the seismic isolation element 10 is also embedded in the second coupling plate 30 and fixed to the second bonding plate 3 through the bolt 40. The upper part of the recess. In the seismic isolation device 1 described above, the seismic isolation element 1 can also be more firmly fixed to the first bonding plate 2A and fixed to the second bonding plate 3A. Further, the force held by the bolt 40 is reduced, and thus an effect similar to the foregoing can be obtained. Further, in the foregoing embodiment, only the χ direction (bidirectional (positive/negative) direction) in Fig. 2 is assumed as the vibration direction ' of the upper portion of the structure, and a large number of seismic isolation elements are placed in this direction. However, as shown in Fig. 9 and Fig. 1, it can be assumed that most directions, for example, the χ direction (bidirectional (positive/negative) direction) and the 垂直 direction perpendicular to the 4 Χ direction (bidirectional (positive/negative) direction) As the vibration square of the upper part of the structure, the seismic isolation device 101 shown in FIG. 9 and FIG. 1Q has a seismic isolation element 1G, a first combination plate, a σ 第 第 plate 13G' and one end of each seismic isolation element 1G is fixed on the first, and the mouth plate 120' and the other end 12 of each seismic isolation element 10 is fixed on the second bonding plate 130.

The 10 seismic isolation elements 10F are configured such that the curved portions of the seismic isolation elements 10F are oriented in a direction opposite to the direction of the seismic isolation elements 10D (ie, toward one of the double arrows Y in FIG. 10). Negative) protrudes between the first bonding plate 120 and the second bonding plate 130. The first bonding plate 120 and the second bonding plate 130 are placed such that the four 15 sides are aligned with each other when viewed from above. According to the seismic isolation device 101, the direction of vibration entry is preset, and the seismic isolation elements 101 are placed along the two set directions (the direction indicated by the double arrow X in FIG. 10 and the double arrow Y). Positioned in the direction shown, whereby the vibration of the upper 20 portions generated in the two setting directions can be effectively buffered. In other words, since it is not assumed that energy enters the upper portion from all directions, but that energy is only entered by a specific direction, unlike a conventional case, it is not necessary to perform detailed evaluation when designing the seismic isolation element 10. Moreover, since the shape of the seismic isolation elements 10 is not specifically limited, it is not necessary to increase the cutting accuracy of the seismic isolation elements 10 to the extent of the conventional seismic isolation elements. Therefore, the seismic isolation device 101 can have higher production efficiency both in the design phase and in the manufacturing phase, and thus the seismic isolation device 101 is less expensive. 5 Description of the preferred embodiments of the present invention has been made so far. However, the present invention is not limited thereto. The invention may be modified, omitted, substituted, and otherwise modified within the scope of the invention. The invention is not limited by the foregoing description, and is only limited by the scope of the following claims. 10 For example, in the foregoing embodiment, the seismic isolation device is disposed at the lower portion and then fixed to the lower portion. Then, the upper portion is placed on the seismic isolation device, and the seismic isolation device is fixed to the upper portion. However, the method for providing the seismic isolation device of the present invention may include only arranging the seismic isolation device on the lower portion such that the seismic isolation elements are positioned in a predetermined vibration direction along one of the upper portion to the lower portion of the 15 a step of fixing the seismic isolation device to the lower portion; a step of disposing the upper portion on the I/the seismic isolation device; and a step of fixing the seismic isolation device to the upper portion. Therefore, the order in which the respective steps are performed is not limited to the foregoing - order. In addition, the seismic isolation device of the present invention is not only placed between a foundation (a lower portion) and a building skeleton (an upper portion) of a structure such as a building, a bridge, an elevated road, and an elevated rail, and It is placed between the members constituting the aforementioned structure. The seismic isolation device can be placed, for example, between a floor forming a building and a cover panel placed on the floor. In the example of 21 200920965, the seismic isolation device absorbs the energy acting on the cover, rather than the energy acting on the building skeleton of the structure. Similarly, it can also be placed between a pier that forms a bridge and a bridge that is placed on the pier. 5 INDUSTRIAL APPLICABILITY The present invention relates to a seismic isolation device for buffering an upper portion of a structure relative to a lower portion of the structure, the seismic isolation device comprising a plurality of U-shaped seismic isolation elements, a first bonding plate, and a a second bonding board, and one end of the seismic isolation element is fixed on the first bonding board, and the seismic isolation 10 is fixed on the second bonding board from the other end of the component. Some of the plurality of seismic isolation elements are disposed between the first bonding plate and the second bonding plate in a predetermined direction, and the other plurality of seismic isolation elements are placed on the first bonding plate in a direction opposite to the predetermined direction. Between the second bonding plate. According to the present invention, the production efficiency of the seismic isolation device can be improved both in the design phase and in the manufacturing phase, and thus the seismic isolation device is less expensive to manufacture.
