Description

Seismic isolation device

[0001] The present invention relates to a base isolation device that reduces vibration by using an LM guide, and more particularly, to a base isolation device equipped with an elastic rail that uses the principle of a pendulum to allow the LM guide to naturally return to its origin.

[0002] Typically, when an earthquake occurs, vibrations are transmitted vertically or horizontally to structures such as buildings or facilities. Horizontal vibrations cause the structures to shake and twist violently.

[0003] If the magnitude of the vibration transmitted at this time is large, it can partially damage the structure, reducing its stability and, in severe cases, even cause the structure to collapse.

[0004] In this way, various seismic isolation devices are being developed and used to protect structures and equipment from earthquakes.

[0005] Meanwhile, a Linear Motion Guide (LM Guide) is a machine element installed in a machine tool having a fixed body and a transport body that moves linearly on the fixed body, to enable smooth relative linear motion.

[0006] These LM guides can be applied to seismic isolation devices to absorb horizontal vibrations.

[0007] Fig. 1 is a drawing showing a seismic isolation device with an LM guide installed according to the prior art.

[0008] A conventional seismic isolation device includes an upper bracket (10) that supports an isolation target facility on its upper surface; a lower bracket (20) having a shape corresponding to that of the upper bracket; an LM guide comprising an LM rail (30) each installed diagonally across the inner surface of the upper bracket and the inner surface of the lower bracket, an LM block (40) that slides along the LM rail (30), and a retainer (50) that restricts a steel ball to the LM block (40).

[0009] In addition, the LM block (40) coupled to the LM rail (30) installed on the inner surface of the upper bracket (10) and the LM block (40) coupled to the LM rail (30) installed on the inner surface of the lower bracket (20) can be coupled to each other by interposing a buffer member (70) therebetween.

[0010] In addition, another vibration absorbing part (80) is installed between the upper bracket (10) and the lower bracket (20) together with a guide module to absorb both vertical and horizontal vibrations and prevent the upper bracket (10) and the lower bracket (20) from coming off.

[0011] However, the conventional seismic isolation device having the above configuration has a vibration absorbing part (80) for forced nuclear power plant recovery made of a coil spring. However, the coil spring is expensive and large, so there is a limit to reducing the overall dimensions of the seismic isolation device, which causes various restrictions on the places of use. In addition, if excessive deformation is applied to the coil spring, permanent deformation occurs, causing the tension of the coil spring to be lost.

[0012] The present invention is intended to solve the above-mentioned problem, and the purpose of the present invention is to provide a base isolation device having high base isolation efficiency, which can reduce cost and significantly reduce the outer dimensions of a product by providing an elastic rail (130) that provides an elastic rebound force so that a guide block (120) can naturally return to the center.

[0013] In addition, the present invention is intended to solve the above-mentioned problem, and to provide a base isolation device that improves the base isolation effect and enhances durability by guiding the guide block to be forcibly restored to the center of the elastic rail by the elastic rebound force of the elastic rail.

[0014] In addition, the present invention aims to provide a seismic isolation device that can reduce costs by eliminating the need to install expensive coil springs, reduce the overall outer dimensions of the product, and diversify installation locations.

[0015] In addition, the present invention seeks to provide a seismic isolation device that can improve productivity by simplifying the parts production process.

[0016] In addition, the present invention seeks to provide a seismic isolation device capable of improving durability and operating efficiency by adding an auxiliary elastic body.

[0017] In addition, the present invention seeks to provide a seismic isolation device that can have uniform elasticity by being installed using an 'L' shaped elastic bracket.

[0018] In addition, the present invention aims to provide a seismic isolation device that can increase economic efficiency by using only the minimum amount of raw materials and that is easy and convenient to manage production quality by manufacturing it using a casting (particularly, wax casting) method.

[0081] [Example 1]

[0082] As illustrated in FIGS. 1 to 4, the seismic isolation device according to Embodiment 1 of the present invention is composed of a pendulum-shaped guide module (100), a cover plate (200), and a center module (300).

[0083] The above pendulum-shaped guide module (100) is a device for linear reciprocating motion, and is composed of two pieces, which are mounted symmetrically vertically on the upper and lower parts of the elastic body, respectively, and are arranged to cross each other to perform reciprocating motion in the horizontal direction to reduce vibration.

[0084] More specifically, the pendulum-shaped guide module (100) is composed of a guide rail (110), a guide block (120), an elastic rail (130), a fixed block (140), a support block (150), and a guide bearing (160).

[0085] The above guide rail (110) is a component that guides the movement of the guide block (120), is formed in a straight line, and is fixed diagonally to the cover plate (200).

[0086] The above guide block (120) is mounted to slide along the above guide rail (110).

[0087] Although not shown in the drawing, a ball bearing is inserted between the guide rail (110) and the guide block (120) like a general LM guide to reduce vibration and friction during movement.

[0088]

[0089] Meanwhile, the elastic rail (130) is fixed to the cover plate (200) and functions to guide the guide block (120) to return to the center of the guide rail (110) by elastic force by coming into contact with the guide block (120).

[0090] Specifically, the elastic rail (130) is formed in the shape of an elastic plate, and is formed long so as to be parallel to the guide rail (110) along the direction of movement of the guide block (120).

[0091] In addition, the elastic rail (130) is formed to be inclined toward the cover plate (200) as it goes toward the center, but the incline becomes gentler as it goes toward the center.

[0092] That is, the elastic rail (130) is formed to be concave in the direction of the cover plate (200), and the center is formed gently so as to be almost horizontal.

[0093] Here, the center of the elastic rail (130) is placed on the same line as the center of the guide rail (110).

[0094]

[0095] In addition, the elastic rails (130) are arranged on both sides of the guide rail (110), and both ends are interconnected.

[0096] That is, both ends of the elastic rail (130) are connected in a ‘U’ shape and integrated.

[0097] Additionally, both ends of the elastic rail (130) are fixed to the cover plate (200) by the fixed block (140).

[0098] The above fixed block (140) is formed in a hexahedral shape and is fixed to the cover plate (200).

[0099] Of course, in some cases, the fixed block (140) may be manufactured as an integral part of the cover plate (200).

[0100] In addition, the fixed block (140) has a fixed inclined surface (141) formed on the surface in contact with the elastic rail (130) that is inclined toward the cover plate (200) as it goes toward the center of the elastic rail (130).

[0101] Accordingly, the elastic rail (130) fixed to the fixed block (140) is inclined toward the cover plate (200) as it moves toward the center.

[0102] In addition, the elastic rail (130) is positioned to be spaced apart from the cover plate (200) by the height of the fixed block (140), and thus the center of the elastic rail (130) is positioned to be capable of being bent up and down.

[0103] In some cases, the size of the fixed block (140) can be changed, and a fixing bolt and an additional block can be added to the fixed block (140) to prevent the guide block (120) from being separated from the guide rail (110).

[0104] Additionally, the elastic rail (130) is separated at the center.

[0105] That is, as shown in Fig. 3, the elastic rail (130) is separated at the center, and the ends of the center are spaced apart at a certain interval so that each can be independently bent.

[0106] Meanwhile, the support block (150) is formed in a hexahedral shape and is placed on each side of the center of the guide rail (110) and fixed to the cover plate (200).

[0107] Of course, in some cases, the support block (150) may be manufactured as an integral part of the cover plate (200).

[0108] The above-mentioned support block (150) comes into contact with the center of the elastic rail (130) when it is bent and deformed, thereby supporting the elastic rail (130).

[0109] Additionally, the support block (150) is formed with support slopes (151) that are inclined in opposite directions from the center.

[0110] The above-mentioned support slope (151) is formed to slope toward the cover plate (200) as it moves away from the center.

[0111] As shown in FIG. 4, the above-mentioned support slope (151) supports the center of the elastic rail (130) when the guide block (120) moves to the end of the guide rail (110), thereby increasing the elastic repulsive force of the elastic rail (130).

[0112] Of course, in some cases, the support block (150) may be formed as a flat surface without the support slope (151).

[0113] Meanwhile, the guide bearing (160) is rotatably mounted on each side of the guide block (120), and rotates in contact with the elastic rail (130) when the guide block (120) moves.

[0114] The above guide bearing (160) transmits the elastic force of the elastic rail (130) to the guide block (120), and minimizes friction with the elastic rail (130) to enable natural operation.

[0115] Meanwhile, the cover plate (200) is composed of two pieces, similar to the pendulum-shaped guide module (100), and is arranged symmetrically vertically with respect to the center module (300) and is connected to each of the pendulum-shaped guide modules (100).

[0116] The above central module (300) is a component that provides elasticity in the vertical direction and is made of vibration-proof rubber.

[0117] Of course, the above-mentioned central module (300) can be configured in various ways using soft plastic, spring suspension, or plate spring.

[0118] The seismic isolation device according to Embodiment 1 of the present invention, having the above configuration, supports the guide block (120) to be forcibly returned to the center of the elastic rail (130) by the elastic repulsive force of the elastic rail (130). In addition, since there is no need to install a separate coil spring, it provides the effects of reducing cost, reducing the outer dimensions, and diversifying the installation location. In addition, it provides the effect of quickly and accurately returning the guide block to the center.

[0119] [Example 2]

[0120] As shown in FIGS. 6 and 7, the seismic isolation device according to Embodiment 2 of the present invention is identical to Embodiment 1 in all other configurations except for the pendulum-shaped guide module (100), so a description thereof will be omitted, and the pendulum-shaped guide module (100) will be described in detail.

[0121] The pendulum-shaped guide module (100) according to Example 2 is composed of a guide rail (110), a guide block (120), an elastic rail (130), a fixed block (140), and a guide bearing (160).

[0122] The above guide rail (110) is a component that guides the movement of the guide block (120), is formed in a straight line, and is fixed to the cover plate (200).

[0123] The above guide block (120) is mounted to slide along the above guide rail (110).

[0124] Although not shown in the drawing, a ball bearing is inserted between the guide rail (110) and the guide block (120) like a general LM guide, and the structure is configured to minimize vibration and friction during movement.

[0125] Meanwhile, the elastic rail (130) is fixed to the cover plate (200), and comes into contact with the guide block (120) to guide the guide block (120) to return to the origin to the center of the guide rail (110) by elastic force.

[0126] Specifically, the elastic rail (130) is formed in the shape of an elastic plate, and is formed long so as to be parallel to the guide rail (110) along the direction of movement of the guide block (120).

[0127] In addition, the elastic rail (130) is formed to be inclined toward the cover plate (200) as it goes toward the center, but the incline becomes gentler as it goes toward the center.

[0128] That is, the elastic rail (130) is formed to be concave in the direction of the cover plate (200), and the center is formed gently so as to be almost horizontal.

[0129] Here, the center of the elastic rail (130) is arranged on the same line as the center of the guide rail (110).

[0130] These elastic rails (130) are arranged on both sides of the guide rail (110).

[0131] In addition, the elastic rail (130) is fixed at a fixed distance from the cover plate (200) at the center by a fixed block (140), and both ends are arranged in a free state so that they can be bent up and down.

[0132] Here, the fixed block (140) is formed integrally at the center of the elastic rail (130) and is formed in a shape that protrudes from the center of the elastic rail (130) toward the cover plate (200).

[0133] Additionally, a detachment prevention part (131) is formed protrudingly at both ends of the elastic rail (130).

[0134] The above-mentioned anti-separation portion (131) is formed at each end of the elastic rail (130) and is formed to be inclined so that its height gradually increases in the opposite direction of the seismic isolation plate.

[0135] The above-mentioned anti-separation part (131) prevents the guide block (120) from separating from the elastic rail (130).

[0136] In addition, the elastic rail (130) is manufactured with the center section separated, and can be used by welding during assembly. This is to reduce manufacturing costs. If the length is long, processing costs increase. However, if it is cut in half, it can be manufactured using various methods, such as casting, thereby reducing manufacturing costs.

[0137] [Example 3]

[0138] The seismic isolation device according to Embodiment 3 of the present invention is identical to the pendulum-shaped guide module (100) of Embodiment 2 except that an auxiliary elastic body (170) is additionally included, so only the auxiliary elastic body (170) will be described in detail.

[0139] As shown in Fig. 8, the auxiliary elastic body (170) is provided at both ends of the elastic rail (130) to elastically support the elastic rail (130) in the opposite direction of the cover plate (200).

[0140] The above auxiliary elastic body (170) is a 'V' shaped plate spring with the center folded.

[0141] The above auxiliary elastic body (170) is placed at each end of the elastic rail (130), with one end fixed to the cover plate (200) and the other end placed in contact with the elastic rail (130).

[0142] The auxiliary elastic body (170) above has the function of reinforcing the elastic rebound force that becomes weaker as it goes toward both ends of the elastic rail (130).

[0143] In this way, by providing the auxiliary elastic body (170) at both ends of the elastic rail (130), the overall elastic repulsive force of the elastic rail (130) is improved, enabling rapid return to the origin.

[0144] [Example 4]

[0145] As illustrated in FIG. 9, the seismic isolation device according to Embodiment 4 of the present invention is identical to Embodiment 1 in all other configurations except for the pendulum-shaped guide module (100), so only the pendulum-shaped guide module (100) will be described in detail.

[0146] The pendulum-shaped guide module (100) according to Example 4 is provided with an auxiliary elastic body (170) instead of the support block (150) in the pendulum-shaped guide module (100) according to Example 1.

[0147] The above auxiliary elastic body (170) is mounted on the cover plate (200) and is a dome-shaped plate spring curved in the direction of the elastic rail (130).

[0148] These auxiliary elastic bodies (170) are provided one each on the left and right sides of the elastic rail (130) to support the elastic rail (130) in the opposite direction of the cover plate (200).

[0149] [Example 5]

[0150] As illustrated in FIG. 10, the seismic isolation device according to Embodiment 5 of the present invention has the same configuration as Embodiment 1 except for the pendulum-shaped guide module (100), so only the pendulum-shaped guide module (100) will be described in detail.

[0151] The pendulum-shaped guide module (100) according to Example 5 is composed of a guide rail (110), a guide block (120), an elastic rail (130), a fixed block (140), and a guide bearing (160).

[0152] The above guide rail (110) is a component that guides the movement of the guide block (120), is formed in a straight line, and is fixed to the cover plate (200).

[0153] The above guide block (120) is mounted to slide along the above guide rail (110).

[0154] Although not shown in the drawing, a ball bearing is inserted between the guide rail (110) and the guide block (120) like a general LM guide, and the structure is configured to minimize vibration and friction during movement.

[0155] Meanwhile, the elastic rail (130) is fixed to the cover plate (200), and comes into contact with the guide block (120) to guide the guide block (120) to return to the origin to the center of the guide rail (110) by elastic force.

[0156] Specifically, the elastic rail (130) is formed in the shape of an elastic plate, and is formed long so as to be parallel to the guide rail (110) along the direction of movement of the guide block (120).

[0157] In addition, the elastic rail (130) is fixed at both ends by the fixed block (140) at a certain distance from the cover plate (200), and the center is arranged in a free state so that it can be bent up and down.

[0158] Here, the fixed block (140) is formed integrally at both ends of the elastic rail (130) and has a shape that protrudes in the direction of the cover plate (200).

[0159] In addition, the elastic rail (130) is formed to be inclined toward the cover plate (200) as it goes toward the center, but the incline becomes gentler as it goes toward the center.

[0160] That is, the elastic rail (130) is formed to be concave in the direction of the cover plate (200), and the center is formed gently so as to be almost horizontal.

[0161] Here, the elastic rail (130) is arranged so that its center is in the same line as the center of the guide rail (110), and is arranged on each side of the guide rail (110).

[0162] In addition, the elastic rail (130) is formed so that the center portion is separated and the ends of the center portion are spaced apart at a certain interval so that each can be bent and deformed independently.

[0163] Here, the fixed block (140) is formed integrally with the elastic rail (130) and has a shape that protrudes in the direction of the cover plate (200).

[0164] Additionally, an auxiliary elastic body (170) is provided at the center of the elastic rail (130).

[0165] The above auxiliary elastic body (170) is provided at the center of the elastic rail (130) and elastically supports the elastic rail (130) in the opposite direction of the cover plate (200).

[0166] The above auxiliary elastic body (170) is a 'V' shaped plate spring with the center folded.

[0167] These auxiliary elastic bodies (170) are each arranged symmetrically left and right at the center of the elastic rail (130), one end is fixed to the cover plate (200), and the other end is arranged in contact with the elastic rail (130).

[0168] The above auxiliary elastic body (170) has the function of reinforcing elasticity in the center of the elastic rail (130).

[0169] Accordingly, by providing the auxiliary elastic body (170) at both ends of the elastic rail (130), the overall elastic repulsive force of the elastic rail (130) is improved, enabling rapid return to the origin.

[0170] The above guide bearing (160) is the same as that of Example 1, so a detailed description is omitted.

[0171] [Example 6]

[0172] As illustrated in FIG. 11, the seismic isolation device according to Embodiment 6 of the present invention has the same configuration as Embodiment 1 except for the pendulum-shaped guide module (100), so only the pendulum-shaped guide module (100) will be described in detail.

[0173] The pendulum-shaped guide module (100) according to Example 6 is composed of a guide rail (110), a guide block (120), an elastic rail (130), and a guide bearing (160).

[0174] The above guide rail (110) is a component that guides the movement of the guide block (120), is formed in a straight line, and is fixed to the cover plate (200).

[0175] The above guide block (120) is mounted to slide along the above guide rail (110).

[0176] Although not shown in the drawing, a ball bearing is inserted between the guide rail (110) and the guide block (120) like a general LM guide, and the structure is configured to minimize vibration and friction during movement.

[0177] Meanwhile, the elastic rail (130) is fixed to the cover plate (200), and comes into contact with the guide block (120) to guide the guide block (120) to return to the origin to the center of the guide rail (110) by elastic force.

[0178] Specifically, the elastic rail (130) is formed in the shape of an elastic plate, and is formed long so as to be parallel to the guide rail (110) along the direction of movement of the guide block (120).

[0179] In addition, the elastic rail (130) is formed to be inclined toward the cover plate (200) as it goes toward the center, but the incline becomes gentler as it goes toward the center.

[0180] That is, the elastic rail (130) is formed to be concave in the direction of the cover plate (200), and the center is formed gently so as to be almost horizontal.

[0181] In addition, both ends of the elastic rail (130) are bent into a 'U' shape to have elasticity and are fixed to the cover plate (200).

[0182] That is, both ends of the elastic rail (130) are folded 180 degrees in the direction of the cover plate (200).

[0183] Both ends of the elastic rail (130) provide elastic force in the vertical direction to the elastic rail (130).

[0184] Additionally, the center of the elastic rail (130) is freely positioned so as to be capable of vertical bending deformation.

[0185] Additionally, an auxiliary elastic body (170) is provided at the center of the elastic rail (130).

[0186] The above auxiliary elastic body (170) is provided at the center of the elastic rail (130) and elastically supports the elastic rail (130) in the opposite direction of the cover plate (200).

[0187] The above auxiliary elastic body (170) is a 'V' shaped plate spring with the center folded.

[0188] These auxiliary elastic bodies (170) are each arranged symmetrically left and right at the center of the elastic rail (130), one end is fixed to the cover plate (200), and the other end is arranged in contact with the elastic rail (130).

[0189] In this way, the elastic rail (130) is formed by bending so that both ends have elasticity, and the auxiliary elastic body (170) is provided in the center, so that the elasticity is increased at both ends and the center, reinforcing the elastic rebound force and providing the effect of returning to the starting point more quickly and accurately.

[0190] The above guide bearing (160) is the same as that of Example 1, so a detailed description is omitted.

[0191] [Example 7]

[0192] As shown in Figures 12 to 16, the components of Example 7 of the seismic isolation device according to the present invention are schematically shown. The component is composed of a pendulum-shaped guide module (1000), a cover plate (2000), and a center module (3000).

[0193] The above components are described in detail as follows.

[0194] The above pendulum-shaped guide module (1000) is a device for linear reciprocating motion, and is composed of two pieces, which are mounted symmetrically vertically on the upper and lower parts of the elastic body, respectively, and are arranged to cross each other to perform reciprocating motion in the horizontal direction to reduce vibration.

[0195] Specifically, the pendulum-shaped guide module (1000) is composed of a guide rail (1100), a guide block (1200), an elastic rail (1300), a fixed block (1400), and a guide bearing (1600).

[0196] The above guide rail (1100) is a component that guides the movement of the guide block (1200), is formed in a straight line, and is fixed diagonally to the cover plate (2000).

[0197] The above guide block (1200) is mounted to slide along the above guide rail (1100).

[0198] Although not shown in the drawing, a ball bearing is inserted between the guide rail (1100) and the guide block (1200) like a general LM guide to reduce vibration and friction during movement.

[0199] The above elastic rail (1300) is fixed to the cover plate (2000) and functions to guide the guide block (1200) to return to the center of the guide rail (1100) by elastic force by coming into contact with the guide block (1200).

[0200] Specifically, the elastic rail (1300) is formed in the shape of an elastic plate, and is formed long so as to be parallel to the guide rail (1100) along the direction of movement of the guide block (1200).

[0201] In addition, the elastic rail (1300) is formed horizontally or inclined toward the cover plate (2000) as it moves toward the center, but when installed inclined, the incline becomes gentler as it moves toward the center.

[0202] That is, the elastic rail (1300) is formed to be concave in the direction of the cover plate (2000), and the center is formed gently so as to be almost horizontal.

[0203] Here, the center of the elastic rail (1300) is placed on the same line as the center of the guide rail (1100).

[0204] In addition, the elastic rail (1300) is arranged on each side of the guide rail (1100) and has a rectangular shape with both ends interconnected in a 'U' shape.

[0205] In addition, the elastic rail (1300) is formed with a structure in which the rail width becomes narrower toward the ends in order to overcome the problem of the elastic force increasing as the guide block (1200) moves toward the ends. Accordingly, the elastic rail (1300) is designed so that a uniform elastic force is applied to the guide block (1200).

[0206] In addition, the elastic rail (1300) has a groove (1320) formed in a circular shape in the center toward the cover plate (2000) and a plate-shaped connecting portion (1360) at both ends.

[0207] The above groove (1320) is formed to be slightly larger than the outer diameter of the guide bearing (1600), so that the guide bearing (1600) can be easily positioned in the groove (1320).

[0208] Accordingly, the home portion (1320) is positioned so that the guide bearing (1600) combined with the guide block (1200) moves to both ends of the elastic rail (1300) and then returns to the center.

[0209] The above-mentioned connecting portion (1360) has at least one through hole (1370) on the upper surface, and is connected to the fixed block (1400) through the through hole (1370) and fixed to the cover plate (2000).

[0210] In addition, the outer structure of the elastic rail (1300) is formed to be longer than the movement direction and distance (displacement amount) of the guide block (1200) based on a width that matches the width of the guide bearing (1600).

[0211] In addition, the elastic rail (1300) may additionally be provided with a pair of grooves (1340) located on both sides of the groove (1320) and open inwardly.

[0212] In addition, the elastic rail (1300) may additionally be provided with a separation prevention part (not shown, unnamed) formed at both ends to be inclined so that the height gradually increases from the center to the outside to prevent the guide block (1200) from being separated.

[0213] In addition, the elastic rail (1300) may be formed in a structure in which the width becomes narrower toward both ends when the thickness of the elastic rail (1300) is constant.

[0214] In addition, the elastic rail (1300) can be applied with various spring steels and can be formed with various metal materials such as SPS1 to SPS9, SK5 and its series, and various carbon tool steels.

[0215] The elastic rail (1300) formed in this way has the effect of simplifying the parts production process and, accordingly, also has an economic effect.

[0216] The above fixed block (1400) is formed in a hexahedral shape having at least one through hole and is fixed to the cover plate (2000).

[0217] The above fixed block (1400) is formed in a hexahedral shape as an embodiment of the present invention, but is not limited thereto.

[0218] Additionally, the above fixed block (1400) can be manufactured as an integral part with the cover plate (2000).

[0219] The through hole of the above fixed block (1400) is connected to the through hole (1370) of the above elastic rail (1300) through a fixing bolt.

[0220] Additionally, the above fixed block (1400) may be manufactured integrally with the cover plate (2000) in some cases.

[0221] In addition, the fixed block (1400) has a fixed inclined surface (141) formed on the surface in contact with the elastic rail (1300) that is inclined toward the cover plate (2000) toward the center of the elastic rail (1300).

[0222] Accordingly, the elastic rail (1300) fixed to the fixed block (1400) is inclined toward the cover plate (2000) as it moves toward the center, and is spaced apart from the cover plate (2000) by the height of the fixed block (1400), so that the center of the elastic rail (1300) is arranged to be capable of being bent up and down.

[0223] In addition, the size of the fixed block (1400) can be changed depending on the case, and a fixing bolt and an additional block can be added to the fixed block (1400) to prevent the guide block (1200) from being separated from the guide rail (1100).

[0224] Meanwhile, as illustrated in FIG. 6, a support block (1500) formed in a hexahedral shape can be positioned between the guide rail (1100) and the cover plate (2000) and fixed to the cover plate (2000).

[0225] The above support block (1500) is formed in a hexahedral shape as an embodiment of the present invention, but is not limited thereto.

[0226] Additionally, the support block (1500) may be manufactured integrally with the cover plate (2000) in some cases.

[0227] The above-mentioned support block (1500) is provided with a support slope (151) formed on one side, and allows the height of the elastic rail (1300) to be adjusted.

[0228] Additionally, the support block (1500) may be formed as a flat surface without the support slope (151) in some cases.

[0229] Meanwhile, the guide bearing (1600) is formed in a circular shape with a through hole in the center and is rotatably mounted on both sides of the guide block (1200), and rotates by contacting the elastic rail (1300) when the guide block (1200) moves.

[0230] The above guide bearing (1600) transmits the elastic force of the elastic rail (1300) to the guide block (1200), and minimizes friction with the elastic rail (1300) to enable natural operation.

[0231] The above cover plate (2000) is composed of two pieces, similar to the pendulum-shaped guide module (1000), and is arranged symmetrically vertically with respect to the center module (3000) and is connected to each of the pendulum-shaped guide modules (1000).

[0232] The above central module (3000) is a component that provides elasticity in the vertical direction and is made of vibration-proof rubber.

[0233] In addition, the central module (3000) can be configured in various ways using soft plastic, spring suspension, or plate spring.

[0234] The seismic isolation device according to Example 7 of the present invention, which is configured as described above, is supported so that the guide block (1200) is forcibly restored to the original point toward the center of the elastic rail (1300) by the elastic repulsive force of the elastic rail (1300).

[0235] In addition, it provides the effect of reducing cost, reducing external dimensions, and diversifying installation locations since there is no need to install a separate coil spring.

[0236] In addition, it provides the effect of allowing the guide block to quickly and accurately return to the center.

[0237] [Example 8]

[0238] As shown in FIGS. 7 and 8, the second embodiment of the seismic isolation device according to the present invention is identical to the pendulum-shaped guide module (1000) of Example 7 except that an auxiliary elastic body (1700) is additionally included, so only the auxiliary elastic body (1700) will be described in detail.

[0239] The above auxiliary elastic body (1700) is formed as a plate spring having at least one through hole, and is provided at both ends of the elastic rail (1300) to elastically support the elastic rail (1300) in the opposite direction of the cover plate (2000).

[0240] Specifically, the auxiliary elastic body (1700) is placed at each end of the elastic rail (1300), with one end fixed to the cover plate (2000) and the other end placed in contact with the elastic rail (1300).

[0241] The through hole of the above auxiliary elastic body (1700) is combined with the through hole (1370) of the above elastic rail (1300) and the through hole of the fixing block (1400) and the fixing bolt.

[0242] The above auxiliary elastic body (1700) has the function of reinforcing the elastic rebound force that becomes weaker as it goes toward both ends of the elastic rail (1300).

[0243] Specifically, as shown in FIG. 8, when the guide block (1200) moves to both ends of the elastic rail (1300) due to vibration, a large stress is applied to the elastic rail (1300) by the guide bearing (1600) of the guide block (1200), and a large stress is also applied to the fixing bolt that fixes the elastic rail (1300).

[0244] At this time, the auxiliary elastic body (1700) located at both ends of the elastic rail (1300) reduces the stress applied to the fixing bolt and allows the elastic rail (1300) to smoothly “elastically bend”, thereby improving the overall elastic repulsive force of the elastic rail (1300), and as a quick return to the origin becomes possible, the durability and operating efficiency of the elastic rail (1300) are increased.

[0245] [Example 9]

[0246] As shown in FIGS. 9 and 10, the third embodiment of the seismic isolation device according to the present invention is identical to the elastic rail (1300) of the pendulum-shaped guide module (1000) of Example 7 except that an auxiliary rail (1800) and a clamp (1890) are additionally included, so only the auxiliary rail (1800) and the clamp (1890) will be described in detail.

[0247] The above auxiliary rail (1800) is fixed to the elastic rail (1300) through at least one clamp (1890), is positioned between the elastic rail (1300) and the cover plate (2000), and supports the elastic rail (1300) by contracting and expanding depending on the position of the guide block (1200).

[0248] Specifically, the auxiliary rail (1800) is formed in the shape of an elastic plate having a groove (1820) in the center, and is formed long so as to be parallel to the guide rail (1100) and the elastic rail (1300) along the direction of movement of the guide block (1200).

[0249] The above home portion (1820) is formed to a size corresponding to the size of the home portion (1320) of the elastic rail (1300).

[0250] In addition, the auxiliary rail (1800) is formed to be inclined toward the cover plate (2000) as it moves toward the center, but the incline becomes gentler as it moves toward the center.

[0251] That is, the auxiliary rail (1800) is formed to be concave in the direction of the cover plate (2000), and the center is formed gently so as to be almost horizontal.

[0252] The above clamp (1890) is formed in a 'C' shape, connects the elastic rail (1300) and the auxiliary rail (1800) to each other, and is located between the auxiliary rail (1800) and the cover plate (2000).

[0253] These auxiliary rails (1800) are arranged on both sides of the elastic rail (1300) as an embodiment of the present invention, but one or more may be installed and used depending on the design structure.

[0254] In addition, the auxiliary rail (1800) may additionally have a through hole (1830) in the center of the groove (1820), and a through hole (1330) may additionally be formed in the center of the groove (1320) of the elastic rail (1300), so that the auxiliary rail (1800) and the elastic rail (1300) may be coupled through a fixing bolt.

[0255] At this time, the configuration of the elastic rail (1300) is the same as the configuration of the elastic rail (1300) of the first embodiment of the present invention, so a detailed description is omitted.

[0256] However, the elastic rail (1300) may be formed not only in a structure in which the rail width becomes narrower toward both ends, but also in a form in which the rail width is constant.

[0257] Therefore, the auxiliary rail (1800) and the elastic rail (1300) can be more strongly coupled.

[0258] [Example 10]

[0259] As illustrated in FIGS. 11 to 15, Embodiment 10 of the seismic isolation device according to the present invention is the same as Embodiment 7 except that the shape of the elastic rail (1300) of the pendulum-shaped guide module (1000) is changed, an elastic bracket (1900) is further included in the elastic rail (1300), and the elastic bracket (1900) and the cover plate (2000) are combined. Therefore, only the elastic rail (1300), the elastic bracket (1900), and the cover plate (2000) will be described in detail.

[0260] The above elastic rail (1300) is fixed to the cover plate (2000) and functions to guide the guide block (1200) to return to the center of the guide rail (1100) by elastic force by coming into contact with the guide block (1200).

[0261] Specifically, the elastic rail (1300) is formed in the shape of an elastic plate, and is formed long so as to be parallel to the guide rail (1100) along the direction of movement of the guide block (1200).

[0262] In addition, the elastic rail (1300) is formed to be inclined toward the cover plate (2000) as it moves toward the center, but the incline becomes gentler as it moves toward the center.

[0263] Additionally, the elastic rail (1300) can be formed horizontally.

[0264] That is, the elastic rail (1300) is formed to be concave in the direction of the cover plate (2000), and the center is formed gently so as to be almost horizontal.

[0265] Here, the center of the elastic rail (1300) is placed on the same line as the center of the guide rail (1100).

[0266] In addition, the elastic rail (1300) is formed so that the thickness of the center is thick, and the thickness of both ends is formed so that the thickness of the center is thinner than that of the center.

[0267] In addition, the elastic rail (1300) is arranged on each side of the guide rail (1100) and has a rectangular shape with both ends interconnected in a 'U' shape.

[0268] In addition, the elastic rail (1300) is formed with a structure in which the rail width becomes narrower toward the ends in order to overcome the problem of the elastic force increasing as the guide block (1200) moves toward the ends. Accordingly, the elastic rail (1300) is designed so that a uniform elastic force is applied to the guide block (1200).

[0269] In addition, the elastic rail (1300) has a groove (1320) formed in a circular shape in the center toward the cover plate (2000), a plate-shaped connecting portion (1360) located at both ends, and a second connecting portion (1380) in the shape of a rectangular parallelepiped located on one side of the connecting portion (1360) in the direction of the cover plate (2000).

[0270] The above groove (1320) is formed to be slightly larger than the outer diameter of the guide bearing (1600), so that the guide bearing (1600) can be easily positioned in the groove (1320).

[0271] Accordingly, the home portion (1320) is positioned so that the guide bearing (1600) combined with the guide block (1200) moves to both ends of the elastic rail (1300) and then returns to the center.

[0272] The second connecting portion (1380) has at least one through hole (1370) on the side, and is connected to the elastic bracket (1900) through the through hole (1370) and fixed to the cover plate (2000).

[0273] In addition, the elastic rail (1300) may additionally be provided with a pair of grooves (1340) located on both sides of the groove (1320) and open inwardly.

[0274] In addition, various spring steels can be applied to the elastic rail (1300).

[0275] In addition, the elastic rail (1300) is manufactured by casting (particularly, wax casting).

[0276] This solves the problem that when a carbon steel plate of a certain specification is model-cut using a laser or water jet, the cost increases due to the loss of raw steel plate material caused by the hollow area in the center of the elastic rail (1300), and the width of the elastic rail (1300) increases or decreases depending on the position to provide various elastic repulsive forces depending on the operating position of the guide block (1200), making it difficult to design due to the complex shape, and furthermore, the maximum width of the elastic rail (1300) for cutting the steel plate takes up more space than necessary.

[0277] If the above elastic rail (1300) is produced by casting (especially, wax casting), the above-mentioned problem is solved, and the width of the elastic rail (1300) is manufactured to be constant while using only the minimum raw materials by the casting mold, and the elastic repulsion force design for each position can be relatively easily done by adjusting the thickness of the elastic rail (1300), and since it is a mold production method, it has a great effect on other production quality management.

[0278] Therefore, the elastic rail (1300) formed in this way has an economic effect as well as an effect of simplifying the parts production process.

[0279] The above elastic bracket (1900) is formed in a plate shape having an 'L'-shaped elastic repulsive force, and has at least one elastic rail coupling hole (1920) on one side and at least one cover plate coupling hole (1940) on the other side.

[0280] The above elastic rail coupling hole (1920) is coupled to the through hole (1370) of the elastic rail (1300) through a fixing bolt.

[0281] The above cover plate joining hole (1940) is joined to the cover plate (2000) through a fixing bolt.

[0282] Since the elastic bracket (1900) formed in this way has elastic repulsion force, it is possible to design the guide block (1200) located on the upper portion of the elastic rail (1300) to have uniform elastic force regardless of its position.

[0283] In addition, the material of the elastic bracket (1900) can be applied in various ways, such as metal, plastic, rubber, etc., but it is particularly effective to use a high-carbon steel plate that has been heat-treated after laser or waterjet model cutting.

[0284] The above cover plate (2000) is composed of two pieces, similar to the pendulum-shaped guide module (1000), and is arranged symmetrically vertically with respect to the center module (3000) and is connected to each of the pendulum-shaped guide modules (1000).

[0285] As shown in FIGS. 14 and 15, the cover plate (2000) has a plurality of through holes (2020) so that an elastic bracket (1900) can be fitted therein and combined with a plurality of fixing bolts.

[0286] In addition, the plurality of through holes (2020) can be formed to a size corresponding to the elastic bracket (1900) so that it can be fitted and combined with a plurality of fixing bolts.

[0287] The fourth embodiment of the present invention formed in this way is such that the plurality of elastic brackets (1900) are fitted into the through holes (2020) of the cover plate (2000), and then the elastic brackets (1900) and the cover plate (2000) are joined with a plurality of fixing bolts, and the elastic brackets (1900) and the elastic rail (1300) are joined with a plurality of fixing bolts, so that the cover plate (2000), the elastic brackets (1900), and the pendulum-shaped guide module (1000) can be assembled.

[0288] Accordingly, as illustrated in FIG. 13, in Example 10 of the present invention, the elastic rail (1300) has uniform elasticity regardless of the position of the guide block (1200) located on the upper portion of the elastic rail (1300) through the elastic bracket (1900) having an elastic rebound force in the shape of an 'L'.

[0289] [Example 11]

[0290] As shown in FIGS. 16 and 17, the embodiment 11 of the seismic isolation device according to the present invention has the same configuration as the pendulum-shaped guide module (1000) of the embodiment 7 except for the guide block (1200), so the description thereof is omitted and only the guide block (1200) is described in detail.

[0291] The above guide block (1200) is mounted to slide along the above guide rail (1100).

[0292] Although not shown in the drawing, a ball bearing is inserted between the guide rail (1100) and the guide block (1200) like a general LM guide to reduce vibration and friction during movement.

[0293] In addition, the above guide block (1200) is formed by additionally providing a 'ㄷ' shaped block frame (1250) on the outside of the opposite side that is combined with the above guide rail (1100).

[0294] The above guide block (1200) and block frame (1250) are connected through a plurality of bolts as shown in FIGS. 16 and 17.

[0295] The above block frame (1250) is provided with a pair of guide bearing coupling parts (1260) on each side.

[0296] The above guide bearing coupling part (1260) has a through hole in the center and can be coupled to the guide bearing (1600) through a bolt.

[0297] The bolt for the above combination may be formed as a shoulder bolt, but is not limited thereto.

[0298] The above guide bearing (1600) is located between the pair of guide bearing joints (1260).

[0299] The guide block (1200) of Example 11 of the present invention formed in this way can be formed into a guide block (1200) having a pendulum structure by simply manufacturing a block frame (1250) on a general guide block (1200) and additionally assembling it.

[0300] [Example 12]

[0301] As illustrated in FIG. 19, Example 12 of the seismic isolation device according to the present invention is identical to Example 7 except that it further includes a 'ㄷ' shaped elastic bracket (1900) in the pendulum-shaped guide module (1000), so only the elastic bracket (1900) will be described in detail.

[0302] The above elastic bracket (1900) is located between the elastic rail (1300) and the cover plate (2000), and serves to support the elastic rail (1300) when the guide block (1200) moves to both ends of the elastic rail (1300).

[0303] The above elastic bracket (1900) is formed in a plate shape having an elastic rebound force in the shape of a 'ㄷ', and has at least one elastic rail coupling hole (1920) on one side of both sides connected by bending or machine cutting in the central portion, and has at least one cover plate coupling hole (1940) on the other side.

[0304] The above elastic rail coupling hole (1920) is coupled to the through hole (1370) of the elastic rail (1300) through a fixing bolt.

[0305] The above cover plate joining hole (1940) is joined to the cover plate (2000) through a fixing bolt.

[0306] Since the elastic bracket (1900) formed in this way has elastic repulsion force, it is possible to design the guide block (1200) located on the upper portion of the elastic rail (1300) to have uniform elastic force regardless of its position.

[0307] In addition, the material of the elastic bracket (1900) can be applied in various ways, such as metal, plastic, rubber, etc., but it is particularly effective to use a high-carbon steel plate that has been heat-treated after laser or waterjet model cutting.

[0308] Embodiment 12 of the present invention formed in this way is configured such that the plurality of elastic brackets (1900) are positioned between the cover plate (2000) and the elastic rail (1300), and are combined with the cover plate (2000) and the elastic rail (1300) through a plurality of fixing bolts, thereby assembling the cover plate (2000), the elastic brackets (1900), and the pendulum-shaped guide module (1000). As a result, when the guide block (1200) moves to both ends of the elastic rail (1300), the elastic rail (1300) can be supported.

[0309] [Example 13]

[0310] As illustrated in FIGS. 19 to 21, Example 13 of the seismic isolation device according to the present invention is identical to Example 7 except that the shape of the elastic rail (1300) of the pendulum-shaped guide module (1000) is changed, so only the elastic rail (1300) will be described in detail.

[0311] The above elastic rail (1300) is fixed to the cover plate (2000) and functions to guide the guide block (1200) to return to the center of the guide rail (1100) by elastic force by contacting the guide block (1200).

[0312] Specifically, the elastic rail (1300) is formed in the shape of an elastic plate, and is formed long so as to be parallel to the guide rail (1100) along the direction of movement of the guide block (1200).

[0313] In addition, the elastic rail (1300) is formed to be inclined toward the cover plate (2000) as it moves toward the center, but the incline becomes gentler as it moves toward the center.

[0314] Additionally, the elastic rail (1300) can be formed horizontally.

[0315] That is, the elastic rail (1300) is formed to be concave in the direction of the cover plate (2000), and the center is formed gently so as to be almost horizontal.

[0316] Here, the center of the elastic rail (1300) is placed on the same line as the center of the guide rail (1100).

[0317] In addition, the elastic rail (1300) is arranged on each side of the guide rail (1100) and has a rectangular shape with both ends interconnected in a 'U' shape.

[0318] In addition, the elastic rail (1300) is formed with a structure in which the rail width becomes narrower toward the ends in order to overcome the problem of the elastic force increasing as the guide block (1200) moves toward the ends. Accordingly, the elastic rail (1300) is designed so that a uniform elastic force is applied to the guide block (1200).

[0319] However, the elastic rail (1300) may, depending on the case, be formed not only in a structure in which the rail width becomes narrower toward both ends, but also in a form in which the rail width is constant.

[0320] In addition, the elastic rail (1300) has a groove (1320) formed in a circular shape in the center toward the cover plate (2000), and a connecting portion (1360) formed in a 'ㄷ' shaped plate shape at both ends.

[0321] The above groove (1320) is formed to be slightly larger than the outer diameter of the guide bearing (1600), so that the guide bearing (1600) can be easily positioned in the groove (1320).

[0322] Accordingly, the home portion (1320) is positioned so that the guide bearing (1600) combined with the guide block (1200) moves to both ends of the elastic rail (1300) and then returns to the center.

[0323] The above-mentioned connecting portion (1360) is connected to the elastic rail (1300) and has at least one through hole (1370) formed in a portion protruding in the direction of the cover plate (2000).

[0324] The above through hole (1370) is fixed to the fixed block (1400) or the cover plate (2000) by a connection using a fixing bolt.

[0325] Additionally, the above through hole (1370) can be fixedly connected to the auxiliary elastic body (1700) by a connection using a fixing bolt.

[0326] In addition, the outer structure of the elastic rail (1300) is formed to be longer than the movement direction and distance (displacement amount) of the guide block (1200) based on a width that matches the width of the guide bearing (1600).

[0327] In addition, the elastic rail (1300) may additionally be provided with a pair of grooves (1340) located on both sides of the groove (1320) and open inwardly.

[0328] In addition, the elastic rail (1300) may additionally be provided with a separation prevention part (not shown, unnamed) formed at both ends to be inclined so that the height gradually increases from the center to the outside to prevent the guide block (1200) from being separated.

[0329] In addition, the elastic rail (1300) may be formed in a structure in which the width becomes narrower toward both ends when the thickness of the elastic rail (1300) is constant.

[0330] In addition, the elastic rail (1300) can be applied with various spring steels and can be formed with various metal materials such as SPS1 to SPS9, SK5 and its series, and various carbon tool steels.

[0331] Embodiment 13 of the present invention formed in this way can support the elastic rail (1300) through the 'ㄷ' shaped connecting portion (1360) when the guide block (1200) moves to both ends of the elastic rail (1300). In addition, this has an excellent effect in terms of cost reduction.

[0332] In order to overcome the problem that the elasticity increases as the guide block (1200) moves toward both ends, the elastic rail (1300) of the 7th to 13th embodiments of the seismic isolation device of the present invention is formed in a structure in which the rail width becomes narrower toward both ends. However, depending on the case, the rail width may be formed in various structures including a shape having a constant shape.

[0333] Therefore, the seventh to thirteenth embodiments of the seismic isolation device of the present invention provide the effect of improving the seismic isolation effect and strengthening durability.

[0334] In the above, the configuration and operation of the seismic isolation device according to the present invention have been described in detail and illustrated with drawings, but this is merely an example, and various changes and modifications are possible within the scope that does not depart from the technical spirit of the present invention.
