Referring to FIGS. 1 and 2 , the earthquake-resistant bearing 100 includes an upper plate part 110 and a lower plate part 120 . Various support plate materials used in the construction field may be applied to the upper plate part 110 and the lower plate part 120 .

Referring to FIG. 2 , the upper plate unit 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 that require earthquake-resistant design (for example, sensitive facilities vulnerable to horizontal load action) and facilities that may generate vibration or horizontal loads by themselves. Interpretation is preferred. For example, the target facility 300 may be a water tank (water tank) such as a firefighting water tank, but is not limited thereto. As another example, the target facility may be a fluid tank in which fluid other than water such as oil is stored, a mechanical facility generating vibration according to mechanical operation, a building, a civil structure, and the like.

Referring to FIG. 2 , the lower plate part 120 includes a lower plate 121 installed on an upper surface of the support part 200 . The support part 200 is a structure provided on the ground or a structure to support the target equipment 300 . For example, the support 200 may be provided in a form including a mat foundation concrete layer and concrete blocks (string pads, concrete pads) arranged and installed on top of the mat foundation concrete layer. In addition, as another example, the support part 200 may include concrete pillars protruding upward from the mat foundation concrete layer so as to correspond one-to-one with the seismic bearing 100. However, the implementation 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, illustratively, the upper plate 111 and the lower plate 121 may be provided in various shapes, such as a rectangle, a circle, and a polygon other than a rectangle, on a plane.

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

Referring to FIGS. 1 and 2 , the present earthquake-proof bearing 100 may be provided in a shape in which a lower plate part 120, an earthquake-resistant pad part 140, and an upper plate part 110 are arranged sequentially from the bottom.

Referring to FIGS. 1 and 2 , the upper plate portion 110 may include an upper stopper 112 that protrudes downward from the upper plate 111 and is spaced apart from the outside of the earthquake-resistant pad portion 140 .

In addition, the lower plate portion 120 may include a lower stopper 122 that protrudes upward from the lower plate 121 and is spaced apart from the outside of the earthquake-resistant pad portion 140 .

The upper stopper 112 and the lower stopper 122 may be provided along the outer circumferential direction of the earthquake-resistant pad part 140 in pairs corresponding to directions in which resistance to a horizontal load is to be provided. Illustratively, the upper stopper 112 and the lower stopper 122 may be provided in a form continuously extending along the circumference of the earthquake-resistant pad part 140 . When the earthquake-resistant pad part 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 part 140, so that a horizontal load is applied It is possible to further increase the responsiveness to various horizontal directions. As another example, the upper stopper 112 and the lower spotter 122 are provided in pairs along the outer circumference of the earthquake-resistant pad unit 140, but may be provided in a plurality of pairs spaced at intervals along the circumferential direction. . More specifically, when the earthquake-resistant pad part 140 has a hexahedron (square prism) shape, the upper stopper 112 and the lower stopper 122 are formed on each of the four outer circumferential surfaces of the hexahedron-shaped earthquake-resistant pad part 140. Correspondingly, four upper stoppers 112 and four lower stoppers 122 are disposed (providing resistance against displacement in two directions of the horizontal direction), 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 disposed (resistance to displacement in one of the horizontal directions) to correspond to each of the two outer surfaces facing opposite to each other among the outer surfaces. can As another example, when the earthquake-resistant pad part 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 part 140 .

That is, the upper stopper 112 and the lower stopper 122 are preferably arranged in consideration of the direction to be resisted against a horizontal load (horizontal load applied from the outside or horizontal load caused by vibration generated by the target equipment itself). For example, if it is desired to perform selective resistance only in one direction among horizontal directions, a pair of upper and lower stoppers corresponding to such 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 be in contact with each other when a horizontal displacement of a predetermined (b) or more occurs, and partially overlap each other when viewed from the horizontal direction. 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 dead weight of the target facility 300 on the seismic support 100 for this facility disposed therebetween (for example, if the target facility is a liquid tank, the dead weight considering the maximum capacity of the liquid accommodated therein) and When a vertical load including an impact load is applied, and consequently compression deformation occurs in the earthquake-proof bearing 100 (mainly the earthquake-resistant pad part 140) for this facility, the upper end of the lower stopper 122 is the upper plate 111 ) may be set to form an interval w2 not to interfere with. Similarly, the degree of downward protrusion of the upper stopper 112 is, as shown in (b) of FIG. A vertical load including the final dead weight of the target facility 300 (for example, when the target facility is a liquid tank, considering the maximum capacity of the liquid accommodated therein) and an impact load is applied to the support 100, Accordingly, when compression deformation occurs in the earthquake-resistant bearing 100 (mainly the earthquake-resistant pad part 140) for this facility, a gap w1 is formed so that the lower end of the upper stopper 112 does not interfere with the lower plate 121 can be set so that

That is, for example, when the target facility 300 is a water tank, maximum water that can be accommodated in the target facility 300 seated on the support 200 is accommodated (stored) via the seismic bearing 100 as a medium. Even if a predetermined external force or self-vibration occurs in one state, the upper stopper 112 of the earthquake-resistant 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 .

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

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. The stopper 122 , and the inner stopper may be the upper stopper 112 . Hereinafter, with reference to FIGS. 1 and 2, the upper stopper 112 is illustrated as an outer stopper, and the outer stopper is also given the same reference numeral 112 as the upper stopper 112, and the lower stopper 122 By exemplifying the inner stopper, the same reference numeral 122 as that of the lower stopper 122 will be given to the inner stopper for description.

The movement limiting distance (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 considering a predetermined safety factor for 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 the maximum horizontal displacement.

Referring to FIG. 1 , when a horizontal external force is applied, resistance (primary resistance) is solely performed by the seismic pad unit 140 until the horizontal displacement corresponding to the movement limiting interval (b), and the movement limiting interval (b) is exceeded. From the horizontal displacement, resistance (secondary resistance) can be achieved by a combination of deformation due to contact between the outer stopper 112 and the inner stopper 122 and deformation due to the earthquake-resistant pad part 140 .

The horizontal external force may include, for example, a horizontal load due to an earthquake, but is not limited thereto. As another example, the horizontal external force may include a horizontal load due to sloshing (wave pressure) of a liquid contained in a liquid tank such as a water tank. In addition, the horizontal external force may include an externally applied impact load (eg, impact due to collision). In addition, the horizontal external force may include even a horizontal load due to self-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 located.

For example, when the horizontal external force (horizontal load) is applied, the seismic bearing 100 is applied to the earthquake-resistant pad part 140 against a horizontal external force (first horizontal external force) that causes a displacement smaller than the movement limiting distance (b). can be resisted primarily by Such primary resistance may include elastic resistance by an elastic material included in the earthquake-resistant pad part 140 . On the other hand, when the horizontal external force (horizontal load) is applied, the present seismic bearing 100 has a movement restriction interval ( Up to b) is primarily resisted by the earthquake-resistant pad part 140, and the displacement occurs over the movement limiting interval (b) where the outer stopper (112, upper stopper) and the inner stopper (122, lower stopper) start to come into contact. For the outer stopper 112 and the inner stopper 122, secondary resistance may be added due to deformation after contact.

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

On the other hand, referring to (a) of FIG. 2, when the target facility 300 is transported in a state where the seismic support 100 is installed on the lower surface of the target facility 300, a vertical load is applied to the seismic support 100 The target facility may be transported in a state in which the earthquake-proof bearing 100 is not installed and the earthquake-resistant bearing 100 is not supported (vertical load inactive state). In this way, when the target facility is transported with the present earthquake-proof bearing 100 unsupported, the lower plate part 120 or the earthquake-resistant pad part 140 of the present earthquake-proof bearing 100 is affected by its own weight or external shock to the target equipment. There is a possibility (difficulty) of separation (departure or fall) from the upper plate portion 110 fixed to the lower surface of the.

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

In addition, referring to (a) of FIG. 2, the outer pinhole 112a is formed in a vertical load-free state in which no vertical load is applied to the earthquake-proof bearing 100 at its formation level (height), and the inner pinhole It may be formed to match the formation level of (122a). Here, the vertical load inactive state means that the vertical load is considered as a load applied from the outside, and it is understood that the vertical load inactive state is considered until at least some of the self-weight of the earthquake-resistant bearing 100 is applied. would be preferable

In addition, referring to (a) of FIG. 2, the outer pin hole 112a and the inner pin hole 122a simultaneously cross the outer pin hole 112a and the inner pin hole 122a in a vertical load inactive state. The linear pin member 130 can be formed so that it can be installed.

As described above, the case where the target facility is transported in a state where the seismic bearing 100 installed on the lower surface of the target facility 300 is not supported can be referred to as an example of a vertical load inactive state. By setting the formation level (height) of the outer pinhole to coincide with the formation level of the inner pinhole in this vertical load inactive state (see FIG. 2 (a)), as shown in FIG. 2 (b), the future target When the equipment 300 is seated on the support 200 and a vertical load is applied to the present earthquake-proof bearing 100 interposed between the target equipment 300 and the support 200, compression deformation of the earthquake-resistant pad 140, etc. As the formation level (height) of the outer pin hole is mismatched (deviated) from the formation level of the inner pin hole, breakage of the linear pin member 130 may be naturally induced. Accordingly, even if a separate fastening release or disassembly (separation) operation of the linear pin member 130 is not performed, the fastening is automatically released due to the breakage of the pin, so work (construction) efficiency can be greatly improved.

Meanwhile, referring to FIG. 2 , the outer pin hole 112a and the inner pin hole 122a forming a pair correspond to each other so that the linear pin member 130 can be inserted, in the circumferential direction of the earthquake-resistant pad part 140. It is preferable to form two or more pairs at intervals along. As shown in FIG. When the target equipment 300 with the earthquake-proof support 100 installed in the non-action state is transported, the lower plate part 120 or the earthquake-resistant pad part 140 is fixed to the lower surface of the target equipment by its own weight or external impact. Set to prevent separation (separation or fall) from the upper plate part 110 (so that the lower plate part 120 or the earthquake-resistant pad part 140 can be maintained suspended from the upper plate part 110) It is desirable 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 around the earthquake-resistant pad part 140 .

In addition, in the case of the pin fastening method for the pin hole, while the lower plate part 120 or the earthquake-resistant pad part 140 is suspended from the upper plate part 110 through the linear pin member 130, At least a part of the self-weight of the plate part 120 and the self-weight of the earthquake-resistant pad part 140 is applied to the linear pin member 130, so that the linear pin member 130 is brought into closer contact with the inner circumferences of the pin holes 112a and 122a. Since the frictional force preventing the linear pin member 130 from being separated from the pin holes 112a and 122a can be further increased, a separate additional component for preventing the separation can be omitted or more simplified. For example, an adhesive for preventing detachment may be applied to at least a portion of the outer circumference of the linear pin member 130 (the outer circumference that contacts the inner surface of the pin hole). As another example, at least one end of both ends of the linear pin member 130 may be provided with a head unit (extension unit) for preventing separation.

Illustratively, referring to FIG. 2 , the linear pin members 130 may be installed corresponding to two symmetrical locations around the earthquake-resistant pad unit 140 . As another example, the linear pin members may be installed along the circumference of the earthquake-resistant pad unit 140 at intervals and corresponding to three locations. As another example, the linear fin members 130 are provided at two locations in one direction (longitudinal direction) of the horizontal direction and two locations in a direction (lateral direction) orthogonal to the one direction (longitudinal direction), for a total of four locations. may be installed against it. 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 such that the lower plate part 120 or the earthquake-resistant pad part 140 is at the upper part. It can be set in various ways in consideration of the place and position, the transport conditions of the target equipment, etc. so that it can be more stably suspended from the plate part 110.

The outer pin hole 112a and the inner pin hole 122a may be formed to 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 with a hole size corresponding to the width (eg, diameter) of the linear pin member 130, or a predetermined margin in consideration of manufacturing errors and the like. It can 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 seismic support 100 is interposed between the target facility 300 and the support 200 (a form in which the target facility is supported by the support via the seismic support). ) As the seismic support 100 is seated on the seismic support 100, the seismic pad part 140 will be provided in a material and shape that breaks when elastically compressed deformation occurs in the vertical direction (12 o'clock to 6 o'clock direction based on FIGS. 1 and 2). can

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

Referring to (a) of FIG. 2, when the target equipment 300 is transported in a state where 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.

It may be provided, but is not limited thereto. Also, as another example, the inner earthquake-resistant bearing 100b may be provided to include an upper plate portion, unlike that shown in the drawings. Referring to FIG. 8A, the outer earthquake-resistant bearing 100a may be prepared in a state of being installed (fixed) on the lower surface of the target facility 300, and the inner earthquake-resistant bearing 100b is not the target facility 300 but the support 200 ) can be prepared in an installed (fixed) state. Referring to FIG. 8B, after the target facility 300 is seated on the support 200 via the seismic bearings 100a and 100b for this facility, the height of the protrusion 210 such as a concrete pad or a concrete column (eg, For example, 50 cm) may make it somewhat difficult for a worker to access the inner earthquake-resistant support (100b). Accordingly, the inner earthquake-resistant bearing 100b is fixed on the protrusion 210 of the support 200 without the upper stopper 112 and the lower stopper 122, and the inner earthquake-resistant support 100b is The operation of fixing the base 100b may be omitted.

The vertical load of ) is applied only to the outer earthquake-resistant bearing 100a, and as the outer earthquake-resistant bearing 100a is vertically compressed, the shape of the earthquake-resistant pad part 140 may be compressed and deformed. Accordingly, as the level (height) between the outer pin hole and the inner pin hole of the outer earthquake-resistant bearing 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 fixing release operation. Since it can be automatically released, ease of construction (work) can be secured.
