A lower body 2000, a central body 3000 disposed therebetween, an upper connection module 4000 and a lower connection module 5000. [

The damper damper is disposed between the upper beam and the lower beam. The upper concrete structure of the present invention may be embodied as a beam structure including an upper beam or a lower beam. The upper body 1000 and the lower body 2000 of the vibration damper And the upper body 1000 is disposed on the upper part so as to be coupled to the upper beams 20 and 40 of the building structure having the upper end as a concrete structure as shown in FIG. (2000) is disposed at the lower portion so as to be coupled to the lower beams (20, 40) of a building structure having a lower end portion implemented as a concrete structure as shown in FIG. The central body 3000 is disposed at an intermediate portion between the upper body 1000 and the lower body 2000 and has an upper end coupled to the upper body 1000 and a lower end coupled to the lower body 2000.

The upper connection module 4000 interconnects the lower end of the upper body 1000 with the upper end of the center body 3000. The upper body 1000 and the central body 3000 may be coupled to each other do. The lower connection module 5000 connects the upper end of the lower body 2000 and the lower end of the central body 3000 to each other so that the lower body 2000 and the central body 3000 can be friction- do.

According to this structure, the vibration damper of the earthquake-proof reinforced concrete reinforced damping damping system according to an embodiment of the present invention can prevent the vibration of the upper body 1000 coupled to the upper beams 20, 40 when an external load such as a wind or an earthquake acts, And the lower body 2000 coupled to the lower beams 20 and 40 are moved relative to the central body 3000 by friction, and the external load is damped and friction damped by the frictional force generated thereby, Stability can be enhanced.

It is preferable that the upper connection module 4000 and the lower connection module 5000 are formed so as to limit a relative friction movement distance of the upper body 1000 and the lower body 2000 with respect to the central body 3000. The upper connection module 4000 and the lower connection module 5000 may be configured so that the maximum static friction force by the upper connection module 4000 and the maximum static friction force by the lower connection module 5000 are equal to each other But are preferably configured differently according to one embodiment of the present invention.

Meanwhile, as described above, the vibration damper according to the embodiment of the present invention firstly frictionally damps the external load by the relative friction movement of the upper body 1000 and the lower body 2000 with respect to the center body 3000 And then the external force of the central body 3000 is plastically deformed after the first frictional damping and the second external damping can be damped.

According to this structure, the vibration damping damper according to the embodiment of the present invention performs the primary friction damping function by the relative friction movement of the upper body 1000 and the lower body 2000 with respect to the center body 3000, And has a vibration damping characteristic in that it performs a secondary damping function by self-deformation of the body 3000. When the external body load is relatively small, the central body 3000 is in an elastically deformed state, And it has seismic characteristics in that it improves the earthquake resistance. Therefore, the vibration damping damper according to an embodiment of the present invention functions as a hybrid damper having both vibration and seismic characteristics according to the magnitude of the external load.

Next, we will examine each configuration in more detail.

The central body 3000 is self-deformed so as to perform a secondary damping operation after the primary friction damping as described above. At this time, the upper body 20, 40 and the upper body 1000 The upper body 1000 and the lower body 2000 are structurally higher in strength than the central body 3000 so that the lower body 2000 and the lower body 2000 can yield and deform only the central body 3000 without undergoing yield deformation .

For example, the upper body 1000 and the lower body 2000 include a plate-shaped main plate M arranged in the vertical direction as shown in FIG. 12, And the central body 3000 may be formed in a simple flat plate shape. In some cases, the center body 3000 may be provided with a flange plate F, A plurality of through holes (see Figs. 14 and 15) may be formed so that self-deformation can smoothly occur.

The upper body 1000 and the lower body 2000 are structured such that the flange plate F protruding in a direction perpendicular to both ends of the main plate M is joined so that the strength is strengthened. It can have higher strength.

At least one stiffener S may be mounted on the upper body 1000 and the lower body 2000 so as to protrude from both sides of the main plate M and the upper body 1000 and the lower body 2000, Can be further improved.

The strength of the upper body 1000 and the lower body 2000 can be structurally improved through the flange plate F and the stiffener S. However, the material of the upper body 1000 and the lower body 2000 The strength of the upper body 1000 and the lower body 2000 may be improved in terms of material by applying a material having a higher tensile strength or yield strength.

The upper body 1000 and the lower body 2000 are respectively provided with separate body base plates 1100 and 2100 to receive loads transmitted from the upper beams 20 and 40 and the lower beams 20 and 40 smoothly, The body base plates 1100 and 2100 are connected to the base plate of the concrete reinforcing structure through a bolt.

The damper damper according to an embodiment of the present invention may be installed to reinforce non-structural walls of a building structure rather than a wall structure of the building structure. In this way, the concrete damper of the concrete structure of the building structure, An upper body 1000 and a lower body 2000 coupled to the upper beams 20 and 40 and the lower beams 20 and 40 implemented as a sequence body and a central body 3000 disposed therebetween, Therefore, the installation work is very easy, and the structure can be manually installed by the operator without employing any additional construction heavy equipment.

Particularly, when the height of the building is high and the size of the upper body 1000 and the lower body 2000 is relatively large, the upper body 1000 and the lower body 2000 The main plate M may be formed as a plurality of divided plates (not shown) separated in the horizontal direction and may be welded or bolted in the field.

The upper connection module 4000 and the lower connection module 5000 have the same configuration as those of connecting the upper body 1000 and the lower body 2000 to the central body 3000 but are different from each other, Only the connection module 4000 will be described.

The upper connection module 4000 includes a pair of connection plates 4100 having upper and lower ends both in close contact with upper and lower surfaces of the upper body 1000 and the central body 3000, And a friction pad 4200 inserted and interposed between the connection plates 4100. At this time, any one of the upper body 1000 and the central body 3000 and the connecting plate 4100 are bolted to each other through a long slot hole H2.

For example, as shown in FIG. 12, a slot hole H2 is formed horizontally at the upper end of the connection plate 4100, and a plurality of bolt holes H1 are formed at a lower end thereof. A corresponding slot hole H2 is formed in the upper body 1000 and a plurality of bolt holes H1 are formed in the central body 3000. [ The connection plate 4100 is provided in a pair so as to be closely contacted to both surfaces of the upper body 1000 and the central body 3000. A friction pad 4200 is attached to the inner surface of the connection plate 4100, And is interposed between the body 1000 and the central body 3000 and the connecting plate 4100.

The coupling bolt B and the nut N are coupled to the bolt hole H1 formed in the coupling plate 4100 and the central body 3000 so that the coupling between the central body 3000 and the coupling plate 4100 is fixed, The coupling bolt B and the nut N are also coupled to the slot hole H2. A separate washer W having a large frictional area is inserted between the coupling bolt B and the nut N at this time . When the coupling bolt B and the nut N are coupled through the slot hole H2 as described above, the coupling plate 4100 and the upper body 1000 are tightly coupled to each other with the friction pad 4200 therebetween, do.

According to the coupling structure through the slot hole H2, the upper body 1000 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 1000 occurs only when an external load larger than the maximum static frictional force due to contact with the friction pad 4200 is applied.

That is, when an external load greater than the maximum static frictional force due to contact with the friction pad 4200 acts on the upper body 1000, the upper body 1000 moves along the slot hole H2, (3000) is fixed through the bolt hole (H1) and is held in a fixed position with the connection plate (4100). In other words, in a fixed state, the central body 3000 moves relative to the central body 3000 while frictionally moving the upper body 1000 along the slot hole H2.

At this time, the friction pad 4200 may be a variety of friction pads commonly used in the construction field, and the configuration for the friction pad 4200, such as a brake pad used for a brake device of an automobile, As shown in FIG.

The lower connection module 5000 also includes a pair of connection plates 5100 tightly coupled to both sides of the lower body 2000 and the center body 3000 in the same manner as the upper connection module 4000, The lower body 2000 and the central body 3000 and the connecting plate 5100 are inserted into the slot holes H2 (H2) and the connecting plate 5100, , So that the lower body 2000 and the central body 3000 are configured to move relative to each other. This is the same as the structure described in connection with the above-described upper connection module 4000, and a detailed description thereof will be omitted for the purpose of preventing duplication.

As described above, the upper body 1000 and the central body 3000 are connected by the upper connection module 4000 so as to be relatively frictionally movable. The lower body 2000 and the central body 3000 are connected to the lower connection module 5,000). ≪ / RTI > The upper body 1000 and the lower body 2000 are moved relative to the central body 3000 with respect to the upper body 1000 and the lower body 2000 by an external load greater than the maximum static frictional force due to the fastening force of the upper connection module 4000 and the lower connection module 5000, So that the external load is attenuated by such friction movement.

Since the relative friction movement between the upper body 1000 and the lower body 2000 is performed along the slot hole H2, the relative distance of friction movement is limited according to the length of the slot hole H2. Accordingly, after the upper body 1000 and the lower body 2000 are frictionally moved to the maximum extent along the slot hole H2, they can no longer be moved by friction. Then, as described above, the central body 3000 is subjected to plastic deformation And secondly damps the external load.

14 and 15 are a schematic front view and a partially enlarged enlarged front view of an earthquake-proof reinforced concrete reinforced damping damping system in which the vibration damping damper and the concrete reinforcing structure of the present invention are connected to each other. The central body of Figs. 14 and 15 has a structure in which a through hole is additionally formed, unlike the case shown in Fig. The body base plates 1100 and 2100 disposed at the upper and lower ends of the vibration damper and the lower body are connected to the base plate 100 disposed in the concrete body / concrete sequence body, which is embodied as an upper beam and a lower beam, The plate 100 can prevent or reduce the possibility of concrete damage to the upper beam and the lower beam formed by the concrete body / concrete sequence body by increasing the strength through the reinforcing body 300, thereby providing a reinforced earthquake-resistant structure.

The above embodiments illustrate examples of the present invention. The present invention can be applied to a structure including a concrete body, a concrete body constraining steel bar, a base plate, and an anchor portion, and a reinforced concrete reinforced concrete structure having such a concrete reinforcing structure Various modifications are possible within the scope of providing a vibration suppression damping system.
