Referring to FIG. 2 , the upper plate part 110 includes an upper plate 111 installed on the lower surface of the target facility 300 . Here, the target facility 300 broadly refers to various facilities such as facilities requiring seismic design (eg, sensitive facilities vulnerable to horizontal load action) and facilities that may generate vibrations or horizontal loads by themselves. It is preferable to be interpreted. For example, the target facility 300 may be a water tank (water tank) such as a fire water tank, but is not limited thereto. As another example, the target facility may be a fluid tank in which a fluid other than water such as oil is stored, a mechanical facility in which vibration is generated according to the operation of a machine, a building, a civil structure, and the like.

Referring to FIG. 2 , the lower plate part 120 includes a lower plate 121 installed on the upper surface of the support part 200 . The support unit 200 is a structure provided on the ground or a structure to support the target facility 300 . For example, the support 200 may be provided in a form including a concrete block (line pad, concrete pad) arranged and installed on top of the mat-based concrete layer and the mat-based concrete layer. In addition, as another example, the support 200 may include a concrete column formed to protrude upward from the mat-based concrete layer so as to correspond to the earthquake-resistant bearing 100 in a one-to-one manner. However, the embodiment of the support unit 200 is not limited thereto, and may be provided in the form of a facility support structure obvious to those skilled in the art or in the form of various facility support structures developed in the future.

Also, by way of example, the upper plate 111 and the lower plate 121 may be provided in various shapes such as a square shape, a circle shape, or a polygon other than a square shape on a plane.

In addition, referring to FIGS. 1 and 2 , the earthquake-resistant bearing 100 includes an earthquake-resistant pad unit 140 disposed (interposed) between the upper plate 111 and the lower plate 121 . A more detailed description of the seismic pad unit 140 will be described later.

Referring to FIGS. 1 and 2 , the earthquake-resistant bearing 100 may be provided in a shape arranged in the order of the lower plate part 120 , the earthquake-resistant pad part 140 , and the upper plate part 110 from the bottom.

1 and 2 , the upper plate part 110 may include an upper stopper 112 that protrudes downwardly from the upper plate 111 and is spaced apart from the earthquake-resistant pad part 140 .

Also, the lower plate part 120 may include a lower stopper 122 that protrudes upward from the lower plate 121 and is spaced apart from the earthquake-resistant pad part 140 .

The upper stopper 112 and the lower stopper 122 may be provided along the outer circumferential direction of the earthquake-resistant pad unit 140 in pairs to correspond to the direction in which the resistance to the horizontal load is to be provided. Illustratively, the upper stopper 112 and the lower stopper 122 may be provided to continuously extend along the circumference of the earthquake-resistant pad unit 140 . When the earthquake-resistant pad unit 140 has a cylindrical shape, the upper stopper 112 and the lower stopper 122 are continuously extended along the circumference of the cylindrical earthquake-resistant pad unit 140, so that a horizontal load is applied. Responsiveness to various horizontal directions can be further improved. As another example, the upper stopper 112 and the lower spotter 122 may be provided in pairs along the outer periphery of the earthquake-resistant pad unit 140 , and may be provided in a plurality of pairs spaced apart from each other at intervals along the circumferential direction. . More specifically, when the earthquake-resistant pad part 140 has a hexahedral (square prism) shape, the upper stopper 112 and the lower stopper 122 are the four outer circumferential surfaces of the hexahedral-shaped earthquake-resistant pad part 140, respectively. Four of the upper stoppers 112 and the lower stoppers 122 are respectively arranged to correspond to each other (providing resistance to the occurrence of displacement in two of the horizontal directions), or four earthquake-resistant pad parts of the hexahedral earthquake-resistant pad part 140 (140) Two upper stoppers 112 and two lower stoppers 122 are respectively disposed to correspond to each of the two oppositely facing outer surfaces of the outer surfaces (providing resistance to occurrence of displacement in one of the horizontal directions) can As another example, when the earthquake-resistant pad unit 140 has a cylindrical shape, a plurality of upper stoppers 112 and lower stoppers 122 may be disposed at intervals along the circumferential direction of the earthquake-resistant pad unit 140 .

That is, the upper stopper 112 and the lower stopper 122 are preferably arranged in consideration of the direction to resist the horizontal load (horizontal load applied from the outside or a horizontal load caused by vibration generated by the target facility itself). For example, if only a selective resistance to any one of the horizontal directions is desired, a pair of upper and lower stoppers corresponding to the one direction may be disposed.

In addition, referring to FIG. 1 , the upper stopper 112 and the lower stopper 122 protrude so that they can come into contact with each other when a horizontal displacement of more than a predetermined (b) occurs, so that when viewed from the horizontal direction, some regions overlap each other This is preferable.

In addition, referring to FIGS. 1 and 2 (b) together, the degree of upward protrusion of the lower stopper 122 is, as shown in FIG. The final self-weight of the target facility 300 on the seismic support 100 for this facility disposed between while seated on the When a vertical load including an impact load is applied, and as a result, compression deformation occurs in the seismic support 100 (mainly the seismic pad part 140) for this facility, the upper end of the lower stopper 122 is the upper plate 111 ) and may be set to form a gap w2 that does not interfere with it. Similarly, the degree of downward protrusion of the upper stopper 112 is, as shown in FIG. A vertical load including the final weight of the target facility 300 (for example, its own weight considering the maximum capacity of the liquid accommodated therein when the target facility is a liquid tank) and an impact load is applied to the support 100 Accordingly, when compression deformation occurs in the seismic support 100 for this facility (mainly the seismic pad part 140), a gap w1 is formed so that the lower end of the upper stopper 112 does not interfere with the lower plate 121. It can be set to be

That is, for example, when the target facility 300 is a water tank, the maximum amount of water that can be accommodated in the target facility 300 seated on the support unit 200 via the seismic support 100 is maximally accommodated (storage). Even if a predetermined external force or self-vibration is generated in one state, the upper stopper 112 of the present seismic bearing 100 protrudes downward to form a gap w1 that does not interfere with the lower plate 121, and the lower stopper 122 ) may protrude upward to form a gap w2 that does not interfere with the upper plate 111 .

Meanwhile, referring to FIGS. 1 and 2 , any one of the upper stopper 112 and the lower stopper 122 has a movement limiting interval outside the inner stopper which is the other of the upper stopper 112 and the lower stopper 122 . (b) may be an outer stopper that is disposed.

For example, referring to FIGS. 1 and 2 , the outer stopper may be an upper stopper 112 , and the inner stopper may be a lower stopper 122 , but is not limited thereto, and vice versa. It is a stopper 122 , and the inner stopper may be an upper stopper 112 . Hereinafter, with reference to FIGS. 1 and 2 , the upper stopper 112 is exemplified as an outer stopper, and the outer stopper is also given the same reference numeral 112 as the upper stopper 112 for explanation, and the lower stopper 122 is The inner stopper is exemplified as an inner stopper, and the same reference numeral 122 as that of the lower stopper 122 will be given to the inner stopper.

The movement limit interval (b) may be set to be less than or equal to the allowable horizontal displacement of the earthquake-resistant pad unit 140 . Here, the allowable horizontal displacement may be a horizontal displacement in consideration of a predetermined safety factor in the maximum horizontal displacement corresponding to the maximum horizontal load that the earthquake-resistant pad unit 140 can cover, but is not limited thereto. For example, the allowable horizontal displacement may be a maximum horizontal displacement.

Referring to FIG. 1, when a horizontal external force is applied, up to the horizontal displacement corresponding to the movement limiting interval b is independently resisted (primary resistance) by the earthquake-resistant pad unit 140, and exceeding the movement limiting interval b From the horizontal displacement, resistance (secondary resistance) may be achieved by a combination of the deformation caused by the contact between the outer stopper 112 and the inner stopper 122 and the deformation by the earthquake-resistant pad unit 140 .

The horizontal external force may include, for example, a horizontal load caused by an earthquake, but is not limited thereto. As another example, the horizontal external force may include a horizontal load caused by sloshing (wave pressure) of a liquid accommodated in a liquid tank such as a water tank. In addition, the horizontal external force may include an impact load applied from the outside (eg, impact due to a collision). In addition, the horizontal external force may include even a horizontal load according to its own vibration, such as mechanical vibration generated according to the characteristics of the target facility itself. In addition, the horizontal external force may include various horizontal loads that can be considered in the area where the target facility is disposed.

For example, this earthquake-resistant bearing 100 is applied to the earthquake-resistant pad unit 140 for a horizontal external force (first horizontal external force) that causes a displacement smaller than the movement limit interval (b) when a horizontal external force (horizontal load) is applied. can be resisted primarily by This primary resistance may include an elastic resistance by the elastic material included in the earthquake-resistant pad unit 140 . On the other hand, this seismic bearing 100 has a movement limiting interval ( Up to b), it is primarily resisted by the earthquake-resistant pad unit 140, and the outer stopper 112 (upper stopper) and the inner stopper 122 (lower stopper) start to come into contact with each other. Secondary resistance may be added by deformation after contact between the outer stopper 112 and the inner stopper 122 .

Meanwhile, referring to FIG. 1 , it is preferable that the inner stopper 122 be spaced apart from the earthquake-resistant pad unit 140 with an interval (a) set to a value greater than or equal to the movement limiting interval (b). Accordingly, when a horizontal displacement greater than or equal to the movement limiting interval (b) occurs, the inner stopper 122 and the outer stopper 112 come into contact with each other and before secondary resistance is formed, the seismic pad unit 140 is moved to the inner stopper ( 122) can be prevented from being first interfered with. In addition, the distance a (the distance between the inner stopper and the seismic pad part) is preferably set to be equal to or greater than the allowable horizontal displacement of the seismic pad part 140 .

On the other hand, referring to FIG. 2 (a), when the present seismic bearing 100 is installed on the lower surface of the target facility 300 and the target facility 300 is transported, a vertical load is applied to the present seismic bearing 100. The target facility can be transported in a state in which the main seismic support 100 is not installed on the lower surface of the target facility so as not to be supported, and the main seismic support 100 is not supported (vertical load inaction state). In this way, when the target facility is transported in a state in which the earthquake-resistant bearing 100 is not supported, the lower plate part 120 or the earthquake-resistant pad part 140 of the earthquake-resistant bearing 100 is the target facility by its own weight or external impact. There is a possibility (difficulty) of being separated (departing or falling) from the upper plate part 110 fixed to the lower surface of the .

To solve this difficulty, referring to FIG. 2 , an outer pin hole 112a is formed in the outer stopper 112 in a horizontal direction, and an outer pin hole 112a is formed in the inner stopper 122. Correspondingly, the inner pin hole 122a may be formed along the horizontal direction.

In addition, referring to Figure 2 (a), the outer pin hole (112a) is the formation level (height) of the vertical load is not applied to the seismic bearing 100 in the state in which the vertical load is not applied, the inner pin hole It may be formed to match the formation level of 122a. Here, it is understood that the vertical load no action state considers the vertical load as a load applied from the outside, and it is understood that the vertical load no action condition is considered until at least some of the self-weight of the seismic bearing 100 is applied. It would be desirable

In addition, referring to Figure 2 (a), the outer pin hole (112a) and the inner pin hole (122a) in a state in which the vertical load is not applied, the outer pin hole (112a) and the inner pin hole (122a) to cross at the same time The linear pin member 130 may be formed to be installed.

As described above, the case where the target facility is transported in an unsupported state of the seismic support 100 installed on the lower surface of the target facility 300 may be referred to as an example of a state in which a vertical load is not applied. By setting the formation level (height) of the outer pinhole to match the formation level of the inner pinhole in this normal load non-action state (see Fig. 2(a)), as shown in Fig. 2(b), the future target As the facility 300 is seated on the support unit 200, when a vertical load is applied to the main seismic bearing 100 interposed between the target facility 300 and the support unit 200, compression deformation of the earthquake-resistant pad unit 140, etc. As a result, the formation level (height) of the outer pin hole is mismatched (displaced) from the formation level of the inner pin hole, and the breakage of the linear pin member 130 may be naturally induced. Accordingly, even if a separate release or disassembly (separation) operation for the linear pin member 130 is not performed, the coupling is automatically released due to pin breakage, thereby greatly increasing work (construction) efficiency.

Meanwhile, referring to FIG. 2 , the outer pin hole 112a and the inner pin hole 122a that are paired to correspond to each other so that the linear pin member 130 can be inserted are formed in the circumferential direction of the earthquake-resistant pad unit 140 . It is preferable that two or more pairs are formed at intervals along each other. The number of pairs in which two or more pairs of these outer and inner pinhole pairs are formed and the positions at which each pair is formed are determined in a state in which the seismic bearing 100 is not supported (vertical load) as shown in FIG. When the target facility 300 installed with the seismic support 100 viewed in a non-action state) is transported, the lower plate part 120 or the seismic pad part 140 is fixed to the lower surface of the target facility by its own weight or external impact. Set to prevent separation (departure or fall) from the upper plate part 110 (so that the lower plate part 120 or the earthquake-resistant pad part 140 can be suspended and maintained with respect to the upper plate part 110) It is preferable to be Illustratively, referring to FIG. 2 , two pairs of the outer pin hole 112a and the inner pin hole 122a may be formed symmetrically with respect to the earthquake-resistant pad unit 140 .

In addition, in the case of a pin fastening method for such a pin hole, while the lower plate part 120 or the earthquake-resistant pad part 140 is suspended with respect to the upper plate part 110 through the linear pin member 130 , the lower part At least a portion of the self weight of the plate unit 120 and the self weight of the seismic pad unit 140 is applied to the linear pin member 130, so that the linear pin member 130 is more closely attached to the inner periphery of the pin holes 112a and 122a. Since the frictional force that prevents the linear pin member 130 from being separated from the pin holes 112a and 122a can be further increased, a separate additional configuration for preventing the above separation can be omitted or more simplified. For example, on the outer periphery of the linear pin member 130 (the outer periphery in contact with the inner surface of the pin hole), an adhesive for preventing separation may be applied to at least a partial region. As another example, at least one end of both ends of the linear pin member 130 may be provided with a separation preventing head portion (extended portion).

By way of example, referring to FIG. 2 , the linear pin member 130 may be installed corresponding to two symmetrical places around the earthquake-resistant pad unit 140 . As another example, the linear pin member may be installed corresponding to three places at intervals along the circumference of the earthquake-resistant pad unit 140 . As another example, the linear pin member 130 is located at two places in one direction (longitudinal direction) in the horizontal direction, and two places in a direction (transverse direction) orthogonal to the one direction (longitudinal direction), in a total of four places. may be installed for The installation position of the preceding pin member 130, that is, the formation position of the outer pin hole 112a and the corresponding inner pin hole 122a, is the lower plate part 120 or the earthquake-resistant pad part 140 is the upper part. It can be set in various ways in consideration of the location and location to be more stably suspended with respect to the plate unit 110, and the conditions for transporting the target equipment.

The outer pin hole 112a and the inner pin hole 122a may be formed in a size into which the linear pin member 130 can be inserted. Illustratively, the outer pin hole 112a and the inner pin hole 122a are formed to have a hole size corresponding to the width (eg, diameter) of the linear pin member 130 , or a predetermined margin in consideration of manufacturing errors, etc. It may be formed with an enlarged hole size to have teeth.

The linear pin member 130 is a target facility 300 in a form in which the present seismic bearing 100 is interposed between the target facility 300 and the support unit 200 (the target facility is supported on the support through the main seismic bearing as a medium). ) to be provided in a material and shape that is broken when deformation occurs when the earthquake-resistant pad part 140 is elastically compressed in the vertical direction (12 o'clock - 6 o'clock direction based on FIGS. 1 and 2) as it is seated on the present earthquake-resistant support 100. can

For example, the linear pin member 130 may be provided of a material including plastic, but is not limited thereto, and is caused by shear stress applied when the target facility 300 is seated with respect to the support unit 200 . It can be provided in a variety of brittle materials that can break.

Referring to (a) of Figure 2, when the target facility 300 is transported in a state in which the earthquake-resistant bearing 100 is not supported and the vertical load is not applied, the linear pin member 130 has an outer pin hole and an inner pin hole. is disposed across the, the lower plate part 120 or the seismic pad part 140 is fixed to the lower surface of the target facility 300 by its own weight or an external impact applied during transport of the target facility 300.

Referring to FIG. 8A , the outer seismic support 100a may be prepared in a state of being installed (fixed) on the lower surface of the target facility 300 , and the inner seismic support 100b is not the target facility 300 but the support 200 ) can be prepared in the installed (fixed) state. Referring to Figure 8b, after the target facility 300 is seated on the support unit 200 via the seismic support (100a, 100b) for this facility, the height of the protrusion 210 such as a concrete pad, a concrete column, etc. (for example, For example, 50 cm), the operator's access to the inner seismic bearing (100b) may be somewhat difficult.

Accordingly, as the level (height) between the outer pin hole and the inner pin hole of the outer seismic support 100a is shifted, the linear pin member 130 is broken, so that the fixation by the linear pin member 130 can be performed without a separate fixation release operation. Since it can be automatically released, the ease of construction (work) can be secured.

Referring to Figure 8b, after the target facility 300 is seated on the support unit 200 via the seismic support (100a, 100b) for this facility, the outer seismic support (100a) located in the outer peripheral area accessible to the operator may be fixed to the protrusion 210 of the support 200 using a fixing unit such as a bolt.
