Description

Damping damper {Aseismic Damper}

The present invention relates to a vibration damper. More specifically, the upper body and the lower body coupled to the upper beam and the lower beam of the building structure, respectively, and the central body disposed therebetween to combine relative friction movement, when an external load such as wind or earthquake, The primary friction damping process through the relative frictional movement of the upper body and the lower body with respect to the center body, and the secondary damping process according to the self-deformation of the center body are carried out sequentially, so that both the vibration damping and the earthquake-resistant characteristics according to the external load are achieved. It relates to a composite damping damper having.

The recent series of massive earthquakes around the world have caused massive casualties and astronomical damages. As a result, the awareness of earthquakes is spreading in general.

Structural methods that respond to earthquake loads are divided into seismic, vibration and seismic isolation. In the case of the earthquake-resistant structure, the structure is resistant to the input seismic force, and the damping structure reduces the seismic force to some extent through the damping device having the damping, and the damper absorbs the input seismic energy, The seismic structure separates the structure from the ground and can be viewed in a form that minimizes the seismic force transmitted to the building.

Earthquake-resistant structures, in which energy caused by horizontal forces such as wind and earthquakes are dissipated through deformation of the main structure, cause damage to the entire structure in the event of a disaster, and do not reduce seismic force. In addition, the seismic isolation structure can exert great effect in absorbing a lot of seismic energy in the Gangjin area, but in Korea, there are few cases of application in building structures due to cost and other problems.

Vibration dampers are classified into passive, semi-active, and active vibration suppressors according to their control methods. Passive vibration suppressors, in which no separate energy source is used, are generally applied. In addition, the passive vibration isolation system can be classified into the following types according to the energy dissipation type. Viscous dampers using velocity - dependent viscous materials; A viscoelastic damper having velocity and strain dependent properties using a viscous material and an elastic material together; A steel damper that dissipates energy using hysteresis characteristics after the yield of the metal material; A friction damper for converting the input energy into thermal energy by friction to dissipate energy.

Viscous dampers and viscoelastic dampers are advantageous in that they have little residual deformation. However, due to the necessity of continuous maintenance and dependence on temperature and frequency, due to the difficulties of control, . Steel dampers have a relatively stable hysteretic behavior depending on the characteristics of the applied steel, but they have the disadvantage of having to replace parts after a disaster due to residual deformation. In addition, the friction damper has a very stable hysteresis characteristics, but also has the disadvantages such as the wear of the friction material due to the friction repeated as well as the problem caused by the friction heat.

The present invention has been invented to solve the problems of the prior art, an object of the present invention is the upper body and the lower body coupled to the upper beam and the lower beam of the building structure, respectively, and the central body disposed therebetween mutual friction When coupled to move, and when external loads such as wind or earthquake are applied, the primary friction damping process for external loads can be performed by the relative frictional movement of the upper and lower bodies relative to the central body to improve the safety of the building structure. It is to provide a damping damper that can be.

Another object of the present invention is to perform a secondary damping process according to the self-deformation of the center body after the first friction damping process according to the relative frictional movement of the upper body and the lower body with respect to the central body, so that the damping and It is to provide a composite damping damper having both seismic characteristics.

Another object of the present invention is to form the first friction damping process and the second damping process to occur in sequence, thereby restoring the damage to the parts by replacing only the components of the corresponding damping portion generated according to the magnitude of the external load It is to provide a damping damper that can be completed to minimize the maintenance reinforcement work.

In this case, the upper connection module and the lower connection module may be formed to limit the relative frictional movement distance of the upper body and the lower body with respect to the central body.

In addition, the maximum static frictional force by the upper connection module and the maximum static frictional force by the lower connection module may be configured to be different from each other.

In addition, the central body may be formed to plastically deform and secondary damp the external load after primary friction damping due to relative frictional movement between the upper body and the lower body.

In addition, the upper body and the lower body may be formed to have a structurally higher strength than the central body.

At this time, the upper body and the lower body is the main plate disposed in the vertical direction; And it may be configured to include a flange plate coupled to the right and left sides of the main plate in a right direction.

In addition, at least one stiffener may be mounted on the main plate of the upper body and the lower body so as to protrude on both sides.

In addition, the main plate may be formed as a plurality of divided plates to be detachably coupled.

On the other hand, the upper connection module is a pair of connecting plate which is coupled to both sides of the upper and lower ends of the upper body and the center body in close contact respectively; And a friction pad interposed between the upper body and the central body and the connection plate, wherein one of the upper body and the central body and the connection plate can be bolted to each other through a long slot hole.

In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

The vibration damping damper according to an embodiment of the present invention is an apparatus for damping an external load by its own stiffness and resistance to deformation and history due to frictional force and includes an upper body 100 and a lower body 200, A central body 300, an upper connection module 400 and a lower connection module 500.

The upper body 100 and the lower body 200 are disposed at the upper and lower portions, respectively. The upper body 100 is formed at an upper portion of the upper structure so as to be coupled to the upper structure beam 10 of the building structure, And the lower body 200 is disposed at the lower portion so that the lower end thereof can be coupled to the lower beam 20 of the building structure as shown in Fig. The central body 300 is disposed in the middle portion between the upper body 100 and the lower body 200, the upper end is coupled to the upper body 100 and the lower end is coupled to the lower body 200.

The upper connection module 400 interconnects the lower end of the upper body 100 and the upper end of the central body 300, and connects the upper body 100 and the central body 300 to allow relative frictional movement with respect to each other. do. The lower connection module 500 interconnects the upper end of the lower body 200 and the lower end of the central body 300, and connects the lower body 200 and the central body 300 to allow relative frictional movement with respect to each other. do.

According to this structure, the damping damper according to an embodiment of the present invention has a lower body coupled to the upper body 100 and the lower beam 20 coupled to the upper beam 10 when an external load such as wind or earthquake is applied. Since the body 200 moves relative friction with respect to the central body 300, and the external load is attenuated by friction damping by the friction force generated, the stability of the building structure can be enhanced.

The upper connection module 400 and the lower connection module 500 is preferably formed to limit the relative frictional movement distance of the upper body 100 and the lower body 200 with respect to the central body 300, which is It can be achieved through a coupling structure using a slot hole (H2) and the coupling bolt (B) to be described later. In addition, the upper connection module 400 and the lower connection module 500 may be configured such that the maximum static frictional force by the upper connection module 400 and the maximum static frictional force by the lower connection module 500 are equal to each other. Otherwise, it is preferable to be configured differently according to one embodiment of the present invention.

On the other hand, the damping damper according to an embodiment of the present invention is to damp the external load primary friction by the relative friction movement of the upper body 100 and the lower body 200 with respect to the central body 300 as described above. Afterwards, if the external load of the frictional damping exceeds the limit, the central body 300 is plastically deformed after the primary frictional damping and is formed to be capable of secondary damping of the external load.

According to this structure, the damping damper according to an embodiment of the present invention performs a primary friction damping function by the relative frictional movement of the upper body 100 and the lower body 200 with respect to the central body 300, and then the center. It has a damping characteristic in that it performs a secondary damping function by self-deformation of the body 300, and when the external load is relatively small, the stiffness of the structure as the stiffness of the central body 300 in its elastic deformation state. It has seismic characteristics in that it promotes. Therefore, the damping damper according to an embodiment of the present invention acts as a hybrid damper having both damping and seismic characteristics according to the magnitude of the external load.

Next, let's look at each configuration in more detail.

As described above, the central body 300 deforms itself so as to act as a secondary damping after the first friction damping. In this case, the upper body 100 and the lower body coupled to the upper beam 10 and the lower beam 20, respectively. The upper body 100 and the lower body 200 are formed to have a structurally higher strength than the central body 300 so that the central body 300 can yield deformation without the yield deformation.

For example, the upper body 100 and the lower body 200, as shown in Figure 2 is a perpendicular to the plate-shaped main plate (M) disposed in the vertical direction, and right and left sides of the main plate (M), respectively It is configured to include a flat flange plate (F) coupled in the direction, the central body 300 may be formed in a simple flat shape, although not shown, in the center of the central body 300 an external load of a certain strength or more A plurality of through holes (not shown) may be formed so that self deformation can occur smoothly.

Therefore, the upper body 100 and the lower body 200 are structured so that the flange plate F protruding in a direction perpendicular to both ends of the main plate M is coupled to the central body 300 It can have higher strength.

In addition, the upper body 100 and the lower body 200 may be mounted with at least one stiffener (S) to protrude to both sides of the main plate (M), through which the upper body 100 and lower body 200 It can further improve the structural strength of.

As such, although the strength of the upper body 100 and the lower body 200 may be structurally improved through the flange plate F and the stiffener S, the materials of the upper body 100 and the lower body 200 are different. By applying a more tensile strength or yield strength material, it is possible to improve the strength of the upper body 100 and the lower body 200 in terms of material.

The upper body 100 and the lower body 200 are connected to each other by upper and lower beams 10 and 210 through separate base plates 110 and 210 so that loads transmitted from the upper and lower beams 10 and 20 can be smoothly transmitted. And the lower beam 20 as shown in FIG.

On the other hand, the damping damper according to an embodiment of the present invention may be additionally installed to reinforce the non-structural wall of the building structure, not the structure forming the wall of the building structure, the upper beam 10 and the lower layer of the building structure in this way Since the upper body 100 and the lower body 200 are respectively coupled to the beam 20 and the center body 300 disposed therebetween is formed separately and combined at the installation site, the installation work is very easy, and separate It is a structure that a worker can install by hand without mobilizing heavy equipment.

Particularly, when the height of the building is high or the size of the upper body 100 and the lower body 200 is relatively large, the upper body 100 and the lower body 200 may be respectively provided to facilitate installation by an operator. Forming the main plate (M) to form a plurality of dividers (not shown) separated in the horizontal direction can be combined by welding or bolting in the field.

Since the upper connection module 400 and the lower connection module 500 have the same configuration as each other connecting the upper body 100 and the lower body 200 and the central body 300 are different from each other, and thus, the upper part Only the connection module 400 will be described.

The upper connection module 400 includes a pair of connection plates 410, the upper and lower ends of which are tightly coupled to both surfaces of the upper body 100 and the central body 300, respectively, and the upper body 100 and the central body 300. It is configured to include a friction pad 420 interposed between the connecting plate 410. At this time, any one of the upper body 100 and the central body 300 and the connecting plate 410 is bolted through the slot hole (H2) formed to one side.

For example, as shown in FIG. 2, a slot hole H2 is formed horizontally at an upper end of the connection plate 410, and a plurality of bolt holes H1 are formed at a lower end thereof. Correspondingly, the slot body H2 in the horizontal direction is formed in the upper body 100, and a plurality of bolt holes H1 are formed in the central body 300. The connecting plate 410 is provided with a pair so as to be in close contact with each of the upper body 100 and the central body 300, respectively, and a pair of friction pads 420 are attached to the inner surface of the connecting plate 410, respectively, It is interposed between the body 100 and the central body 300 and the connecting plate 410.

The coupling bolt B and the nut N are coupled to the bolt hole H1 formed in the connection plate 410 and the central body 300 so that the central body 300 and the connection plate 410 are fixedly fixed. Similarly, the coupling bolt B and the nut N are coupled to the slot hole H2, and a separate washer W having a wider friction area is inserted between the coupling bolt B and the nut N, respectively. . As such, when the coupling bolt B and the nut N are coupled through the slot hole H2, the coupling plate 410 and the upper body 100 are closely coupled with the friction pad 420 interposed by the bolt coupling force. do.

According to the coupling structure through the slot hole H2, the upper body 100 can move within the length of the slot hole H2 along the longitudinal direction of the slot hole H2. Of course, the movement of the upper body 100 occurs only when an external load larger than the maximum static frictional force due to contact with the friction pad 420 is exerted.

That is, when an external load greater than the maximum static frictional force due to contact with the friction pad 420 acts on the upper body 100, the upper body 100 moves along the slot hole H2, and at this time, the central body Since the 300 is fixed through the bolt hole H1, the connection plate 410 is maintained in a fixed position. In other words, the upper body 100 is frictionally moved along the slot hole H2 while the central body 300 is fixed and moves relative to the central body 300.

At this time, the friction pad 420 may be used a variety of friction pads commonly used in the construction field, in addition to the brake pad used in the brake device of the vehicle may be used, such as the configuration of the friction pad 420 is required by the user It can be changed in various ways.

The lower connection module 500 also has a pair of connection plates 510 closely coupled to both sides of the lower body 200 and the central body 300, like the upper connection module 400, and the lower body 200 and the central body. It comprises a friction pad 520 is inserted between the 300 and the connecting plate 510, any one of the lower body 200 and the central body 300 and the connecting plate 510 is a slot hole (H2) By bolt coupling through), the lower body 200 and the central body 300 are configured to move relative friction with each other. This is the same as the structure described in connection with the above-described upper connection module 400, and thus a detailed description thereof will be omitted for the purpose of preventing duplication.

As described above, the upper body 100 and the central body 300 are coupled to each other so as to be capable of relative friction movement by the upper connection module 400, and the lower body 200 and the central body 300 are connected to the lower connection module ( 500) is coupled to the relative friction movement. Therefore, when an external load is applied that is greater than the maximum static frictional force due to the fastening force of the upper connection module 400 and the lower connection module 500, the upper body 100 and the lower body 200 are applied to the central body 300. Relative frictional movements result in damping external loads.

At this time, the relative friction movement between the upper body 100 and the lower body 200 is performed along the slot hole H2, so that the relative friction movement distance is limited according to the length of the slot hole H2. Therefore, after the upper body 100 and the lower body 200 move relative friction to the maximum limit along the slot hole H2, the friction can no longer be moved, and as described above, the central body 300 is plastically deformed. And secondary damping of external load.

4 is a view illustrating various forms of the upper connection module and the lower connection module of the damping damper according to an embodiment of the present invention, Figure 5 is a damping operation state of the damping damper according to an embodiment of the present invention 6 and 7 are views illustrating another form of the upper connection module and the lower connection module of the damping damper according to an embodiment of the present invention.

The upper connection module 400 and the lower connection module 500 may be formed with the same or different maximum static frictional force by the upper connection module 400 as the maximum static frictional force by the lower connection module 500, for example, When the maximum static frictional forces are formed equal to each other, as shown in FIG. 4A, the number of slot holes H2 of the upper connection module 400 and the number of slot holes H2 of the lower connection module 500 is shown. It is preferable that are formed to be the same as each other.

In more detail, as described above, the slot plate H2 is formed in the connection plate 410 of each connection module, the upper body 100 and the lower body 200 coupled to the connection plate 410, respectively. The body 100 and the lower body 200 are configured to move relative friction with respect to the central body 300, wherein the frictional force due to contact with the friction pad 420 is proportional to the fastening force of the coupling bolt B, respectively. This means that it is proportional to the number of coupling bolts (B).

Therefore, as shown in (a) of FIG. 4, the number of slot holes H2 formed in the upper connection module 400 and the lower connection module 500 are equal to each other such that the number of coupling bolts B is the same. By being formed, the maximum static frictional force generated by the upper connection module 400 and the lower connection module 500 may be formed to be equal to each other.

On the other hand, in contrast, the maximum static friction force generated by the upper connection module 400 and the lower connection module 500 may be formed differently, in this case, as shown in (b) and (c) of FIG. The number of slot holes H2 may be different from each other so that the number of coupling bolts B coupled to the upper connection module 400 and the lower connection module 500 is different from each other.

That is, as shown in (b) of FIG. 4, a slot is formed in the upper connection module 400 and the upper body 100 so that a greater number of coupling bolts B may be fastened in the lower connection module 500. The number of slot holes H2 formed in the lower connection module 500 and the lower body 200 may be greater than the number of holes H2, and thus the coupling bolts B may be formed in the lower connection module 500. ) Tightening force is increased to have a greater maximum static friction.

In addition, as shown in FIG. 4C, a slot is formed in the lower connection module 500 and the lower body 200 so that a greater number of coupling bolts B may be fastened in the upper connection module 400. The number of slot holes H2 formed in the upper connection module 400 and the upper body 100 may be larger than the number of holes H2, and thus, the coupling bolts B may be formed in the upper connection module 400. ) Tightening force is increased to have a greater maximum static friction.

Meanwhile, as shown in FIG. 4A, the number of slot holes H2 formed in the upper connection module 400 and the lower connection module 500 is equal to each other such that the number of coupling bolts B is the same. Even when formed, the friction coefficient values of the upper friction pad 420 and the lower friction pad 520 are different so that the maximum static friction force generated by the upper connection module 400 and the lower connection module 500 is formed differently. Can be.

As such, when a difference occurs between the maximum static frictional force generated by the upper connection module 400 and the maximum static frictional force generated by the lower connection module 500, the relative frictional movement of the upper body 100 and the lower body 200 Relative frictional movement of) takes place sequentially.

For example, as shown in FIG. 5A, the maximum static frictional force by the lower connection module 500 is configured to be greater than the maximum static frictional force by the upper connection module 400. When the external load is applied, as shown in (b) of FIG. 5, first, the maximum static frictional force by the upper connection module 400 is relatively small, so that the upper body 100 has a relative friction with respect to the center body 300. Will move. At this time, when the upper body 100 moves relative friction as much as the length of the slot hole (H2), the coupling bolt (B) is engaged with the slot hole (H2) to limit the relative friction movement in that state. Thereafter, as shown in (c) of FIG. 5, the upper body 100 and the central body 300 are simultaneously moved, at which time, the central body 300 is the upper body 100 with respect to the lower body 200. Relative friction moves in the same direction as the moving direction of. In other words, as shown by arrows in FIG. 5C, the lower body 200 moves relative to the central body 300 in the opposite direction to the moving direction of the upper body 100.

The relative friction movement of the upper body 100 and the relative friction movement of the lower body 200 are sequentially performed, and the external load is sequentially friction damped. Then, as shown in FIG. 5 (d) The body 300 is plastically deformed and the external load is secondarily damped.

According to this structure, the damping damper according to the exemplary embodiment of the present invention may not only sequentially perform the first friction damping process in the upper connection module 400 and the lower connection module 500, but also after the primary friction damping, the central body ( Since the secondary damping process by self deformation of 300 occurs, only a specific damping process occurs according to the magnitude of the external load. That is, the primary friction damping process occurs only in the upper connection module 400 for a relatively small external load, and the primary friction damping in both the upper connection module 400 and the lower connection module 500 for a larger external load. The process occurs, and for the external load larger than this, a secondary damping process occurs by deformation of the central body 300 along with a primary friction damping process.

Therefore, since a specific damping process occurs according to the magnitude of the external load, when the external load is destroyed and normally restores the damping damper, the specific damping process occurs without having to replace or repair all the components of the damping damper. Only components related to the location can be replaced. That is, when restoring the damping damper, only partial replacement of the component can be performed according to the magnitude of the external load, thereby minimizing the repair reinforcement work.

On the other hand, the slot hole (H2) is formed in the portion connected to the upper body 100 of the upper connection module 400, as shown in Figure 6 (a), the lower body of the lower connection module 500 Slot hole (H2) is formed in a portion connected to the 200, the upper connection module 400 and the lower connection module 500 is fixed to the central body 300, the upper body 100 and the lower body Although 200 has been described as relative friction movement with respect to the connecting plate 410 fixed to the central body 300, as shown in Figure 6 (b) of the upper body 100 and the lower body 200 The central body 300 with respect to the fixed coupling plate 410 may be configured to move relative friction.

That is, the slot hole (H2) is formed in the portion connected to the central body 300 of the upper connection module 400, the slot hole (H2) in the portion connected to the central body 300 of the lower connection module 500 Is formed, the central body 300 may be configured in a relative frictional movement with respect to the connecting plate 410 fixedly coupled to the upper body 100 and the lower body 200.

This is because the upper body 100 and the lower body 200 and the center body 300 is a relative frictional movement of each other, the principle of operation is the same no matter how configured.

In addition, in the above, one coupling bolt B is coupled to each other through one slot hole H2, and the plurality of slot holes H2 are formed in the upper connection module 400 and the lower connection module 500. As described above, the upper connection module 400 and the lower connection module 500 may be coupled to the plurality of coupling bolts B through one slot hole H2 as shown in FIG. Each slot hole (H2) may be formed in the form.

At this time, for example, when the maximum static frictional force by the upper connection module 400 is configured to be smaller than the maximum static frictional force by the lower connection module 500, as shown in Figure 7 (a) It is preferable that the length of the slot hole H2 formed in the connection module 400 is relatively smaller than the length of the slot hole H2 formed in the lower connection module 500. Accordingly, the slot of the lower connection module 500 is formed. The number of coupling bolts B penetratingly coupled to the hole H2 may be applied.

In addition, as shown in (b) of FIG. 7, the upper connection module 400 and the lower connection module 500 have a slot hole H2 in a horizontal direction, and the upper body 100 and the lower body 200. It may be configured to form a slot hole (H2) in the vertical direction. According to such a configuration, the upper body 100 and the lower body 200 may move relative friction in the horizontal direction with respect to the center body 300, or may move relative friction in the up and down directions, and thus, for external loads in more various directions. Friction damping action can be performed.
