Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Prior to the description, in various embodiments, components having the same configuration will be representatively described in the first embodiment using the same reference numerals, and in other embodiments, only the configuration different from the first embodiment will be described. do.

As illustrated in FIG. 1, the damping haunch according to the first embodiment of the present invention is installed at a beam (B) -pillar (P) junction or a wall-floor junction of a building, so that an external force such as an earthquake may act. In this case, it prevents deformation of buildings as much as possible by resisting seismic force. Here, the building refers to various structures required by the seismic design, and may include, for example, a bridge.

The vibration damping haunch is a vibration damping unit having a horizontal plate 10 and a vertical plate 15, and one side of each of which is supported by the vertical plate 15 and the horizontal plate 10 and having at least one lead core 61 (see FIG. 2). 50, a first link 30 connecting the other side of the vibration suppression unit 50 to the horizontal plate 10, and a second link 40 connecting the other side of the vibration suppression unit 50 to the vertical plate 15. It consists of.

The horizontal plate 10 is formed in a shape surrounding the bottom and both sides of the beam (B) is fixed to the beam (B) by a fastening member such as a bolt, it is made of a steel plate having a predetermined thickness. At this time, the anti-vibration rubber pad 90 is preferably attached to the inner surface of the horizontal plate 10 (the surface where the beam B and the horizontal plate 10 contact), and the anti-vibration rubber pad 90 is a horizontal plate. (10) to be in close contact with the beam (B), and to act as a buffer between the members of different materials, and to absorb the earthquake to improve the seismic performance.

The vertical plate 15 is formed in a shape surrounding the front and both sides of the pillar (P) is fixed to the beam (B) by a fastening member such as a bolt, it is made of a steel plate having a predetermined thickness. At this time, it is preferable that the anti-vibration rubber pad 90 is attached to the inner surface of the vertical plate 15 (the surface where the pillar P and the vertical plate 15 contact), and the anti-vibration rubber pad 90 is a vertical plate. (15) to be in close contact with the pillar (P), and to act as a buffer between the members of different materials, and to absorb the earthquake to improve the seismic performance.

As shown in FIG. 2, the vibration damping unit 50 is coupled to one side of the vibration damping body 60 and the vibration damping body 60 to absorb the seismic force and is supported by the horizontal plate 10 and the vertical plate 15. It is composed of a first bracket 51 and a second bracket 52 coupled to the other side of the damping body 60 and coupled to the first link 30 and the second link 40.

The vibration damping body 60 is composed of a lead core 61 absorbing seismic force in the center and a vibration absorber 62 made of rubber material connected to the lead core 61 around the lead core 61. At this time, the lead core 61 is erected at the center of the vibration damping body 60, the vibration absorber 62 is installed so as to surround the circumference around the lead core 61.

Here, it is preferable that a plurality of reinforcing iron plates C1, C2, ..., Cn are inserted into the damping body 60 in the longitudinal direction of the lead core 61. That is, the reinforcing iron plates C1, C2, ..., Cn reinforce the rigidity of the vibration absorber 62, thereby preventing the vibration absorber 62 from being excessively elastically deformed.

At this time, it is preferable that the reinforcing iron plates C1, C2, ..., Cn are inserted into the mold when the vibration absorber 62 is molded and molded integrally with the vibration absorber 62. Accordingly, since the reinforcing iron plates C1, C2, ..., Cn do not need to be separately assembled to the vibration absorber 62, an effect of reducing the number of assembly operations can be obtained.

A plurality of reinforcing iron plates C1, C2, ..., Cn are arranged in the longitudinal direction of the lead core 61, wherein the first bracket 51 and the second bracket are among the plurality of reinforcing iron plates C1, C2, ..., Cn. Reinforcing iron plates (C1, Cn) are fixed to the 52 and each of the fastening means (5) is preferably made relatively thick to ensure rigidity.

In the damping unit 50 as described above, the lead core 61 is plastically deformed by absorbing seismic force, thereby destroying the molecular structure. At this time, the lead core 61 mounted inside the rubber vibration absorber 62 is 20 ° C. at room temperature. Recrystallized from the original molecular structure. Therefore, the building (particularly a bridge) to which the vibration damping unit 50 is applied has no upper structure by returning the upper structure by the elastic restoring force of the vibration absorber 62 after the earthquake ends, and the lead core 61 returns to the original molecular structure at room temperature. The advantage is that it can be used permanently without maintenance.

That is, as shown in (a) and (b) of Figure 3, when the vibration absorber 62 made of a rubber material is installed in the upper structure and the lower structure, when the earthquake force more than the design earthquake force occurs, the shear deformation of the rubber is greatly And the restoring force of the rubber is gradually increased. Due to the restoring force of the rubber, after the earthquake ends, there is a characteristic that the upper structure is to be restored, thereby satisfying the function as the damping unit 50. Therefore, the vibration damping unit 50 absorbs the seismic energy to reduce the damage by the lead core 61, is easily displaced in the long-term load and resists the short-term load, there is an advantage that maintenance is not required.

The first link 30 is disposed to be inclined downward at an angle with respect to the horizontal plate 10, one end of which is hinged to the horizontal plate 10 via the hinge portion 65, and the other end of the vibration damping unit 50. Is coupled to the other side. Here, the hinge portion 65 is a well-known means for connecting the one end of the horizontal plate 10 and the first link 30 to allow the first link 30 to rotate, and a detailed description thereof will be omitted.

At this time, the coupling of the other end of the first link 30 and the vibration suppression unit 50 is possible by the first coupling means 91 and the second coupling means 92.

The first coupling means 91 is recessed in the coupling protrusion 91a protruding from the end of the first link 30 and the second bracket 52 of the vibration suppression unit 50 so that the coupling protrusion 91a is predetermined. It is comprised by the protrusion groove 91b for fitting in the state which has a clearance. As such, since the first coupling means 91 is configured in a fitting manner rather than a hinge hinge coupling, the size of the end of the first link 30 and the coupling portion of the damping unit 50 can be compactly realized. have.

The engaging protrusion 91a is formed in an elongated shape along the width direction of the first link 30, and the protruding groove 91b is also formed in a long shape corresponding to the shape of the engaging protrusion 91a to thereby form an engaging protrusion ( It is good to make the joining area of 91a) and projection groove 91b as large as possible. In addition, the coupling protrusion 91a is inserted into the protrusion groove 91b with a predetermined clearance so that when the seismic force is input to the first link 30, the first link 30 is connected to the vibration suppression unit 50. It is desirable to be rotatable relative to absorb some energy.

At this time, it is better to absorb the seismic force input to the first link 30 as much as possible by further providing a buffer member 85 of rubber material.

The second coupling means 92 serves to assist the first coupling means 91, and is to prepare for the case where the first coupling means 91 cannot play the role due to the seismic force more than the design seismic force. Here, the second coupling means 92 is fixed to the hinge pin (92a), the other end of the first link 30 and the vibration damping unit 50, respectively, the fixing bracket (92b) rotated about the hinge pin (92a), 92c). Here, since the second coupling means 92 is equally applied to the other end of the second link 40 and the vibration suppression unit 50, it is noted that in FIG. 2, reference is given to the second link 40.

The second link 40 has the same configuration as the first link 30 and is disposed to be inclined upward at a predetermined angle with respect to the vertical plate 15, and one end of the second link 40 has a hinge portion 65 with respect to the vertical plate 15. The hinge is coupled to each other, the other end is hinged to the other side of the damping unit (50). Here, the hinge portion 65 has the same configuration as the hinge portion 65 connecting the first link 30 and the horizontal plate 10, but is not limited thereto and the second link with respect to the vertical plate 15. As long as the structure 40 is rotatable, any may be sufficient.

At this time, the coupling of the other end of the second link 40 and the vibration suppression unit 50 is possible by the first coupling means 91 and the second coupling means 92, and the first coupling means 91 and the first coupling means Since the configuration of the two coupling means 92 is the same as described above, a detailed description thereof will be omitted.

The first link 30 and the second link 40 described above are manufactured in a solid type, but as shown in FIG. 4, the elastic members 81 are formed inside the first link 230 and the second link (not shown). 82 may be configured so that the seismic force can be more effectively absorbed through the elastic members 81 and 82.

Since the first link 230 and the second link have the same configuration, the structure of the first link 230 and the second link will be described in detail.

The first link 230 is a hollow cylindrical casing 75, a first connecting member 71 and a second connecting member 74 coupled to both ends of the casing 75, and an interior of the casing 75. The first rod 78 and the second rod 79 and the casing 75 to be integrally coupled to the second connection member 74 at the first rod 78 and the second rod 79. It consists of the 1st elastic member 81 and the 2nd elastic member 82 which elastically support.

On the inner circumferential surface of one end of the casing 75, a screw thread 75a for screwing with the first connecting member 71 is processed, and on the other end, the second connecting member 74 is accessible and washers 84, which will be described later, The through hole 75b which prevents the entry and exit of 87 is formed.

Inside the casing 75, washers 83 and 84 supporting one end and the other end of the first elastic member 81 and washers 86 supporting one end and the other end of the second elastic member 82, respectively, 87 is provided, and the first elastic member 81 is attached to the two washers 83 and 84 with the washers 83 and 84 extrapolated to the body 78b of the first rod 78. The second elastic member 82 is supported by two washers 86, 87 between the two washers 86, 87, extrapolated to the body 78b of the second rod 79. .

The first connection member 71 is a member that is screwed to one end of the casing 75 and connected to the hinge portion 65, and a connection body 72 and a connection body 72 for connecting to the hinge portion 65. It is formed integrally with the screw thread (75a) formed in the casing 75 is composed of a screw fastening portion (73) for screwing.

At this time, the screw fastening portion 73 should be formed with a moving space 71a so as to be movable when the first rod 78 and the second rod 79 slide together with the second connecting member 74. Of course.

The second connecting member 74 has a structure inserted into the other end of the casing 75, the connecting projection (91a) is formed at the end protruding to the connection body 76 for coupling to the damping unit 50, the connection, Is formed integrally with the body 76 is composed of an insertion fastening portion 77 is inserted into the other end of the casing (75).

At this time, the insertion fastening portion 77 is formed with a screw groove (not shown) for screwing the first rod 78 and the second rod 79, the first rod 78 and the second rod (79) The first rod 78 and the second rod 79 and the second connecting member 74 can be integrally moved when the external force is applied by screwing to the insertion fastening portion 77. That is, when the external force is applied, the first rod 78 and the second rod 79 slides toward the inside of the casing 75 by the length that the insertion fastening portion 77 is drawn into the casing 75, As long as the insertion fastening portion 77 is drawn out of the casing 75, the rod may slide toward the outside of the casing 75. The insertion fastening portion 77 enters and exits through the through hole 75b formed at the other end of the casing 75. Since the two diameters correspond to each other, the insertion fastening portion 77 is slidable in the longitudinal direction while minimizing the flow in the radial direction.

Meanwhile, since the first rod 78 and the second rod 79 are configured in the same manner, the first rod 78 will be mainly described.

The first rod 78 is composed of a head 78a and a body 78b extending smaller in diameter than the head 78a and is integrally fixed to the second connecting member 74 inside the casing 75.

The head 78a is located in the moving space 71a of the screw fastening portion 73 and the body 78b is elongated along the longitudinal direction of the casing 75.

A thread 78c is formed at an end of the body 78b and screwed into a screw groove formed in the insertion fastening portion 77 of the second connection member 74.

At this time, one side washer 83 is extrapolated to one end of the body (78b), the other side washer 84 is extrapolated to the other end of the body (78b), thereby substantially supporting both ends of the first elastic member (81) do.

The first elastic member 81 is installed inside the casing 75 and penetrates through the body 78b of the first rod 78, respectively, at both ends of the body 78b of the first rod 78. It is elastically supported by extrapolated washers 83, 84.

Similarly, the second elastic member 82 is installed inside the casing 75 and penetrates through the body 78b of the second rod 79 and both ends of the body 78b of the second rod 79. Elastically supported by washers 86 and 87 extrapolated to each other.

Here, it is more preferable that the first elastic member 81 and the second elastic member 82 are plate springs which are connected to each other along the longitudinal direction of the casing 75 and have a predetermined elasticity. That is, since the leaf springs 81 and 82 are configured to be in contact with each other, they have a larger elastic force than the coil springs, and thus have a greater resistance to earthquake forces, which is more effective.

With this configuration, the principle that the first link 230 is compressed and tensioned in the second embodiment is as follows.

When no external force is applied, the initial state of the damping link 230 is as shown in FIG.

On the other hand, when the external force is applied, the first rod 78 and the second rod 79 is the casing 75 as long as the insertion fastening portion 77 of the second connecting member 74 is drawn into the casing 75, respectively. Slides toward the inside of the casing, at which time the washers 84 and 87 are moved into the casing 75 by the pressing force of the insertion fastening 77, and the other washer 83 and 86 is moved at one end. The elastic members 81 and 82, which are respectively supported by each other, are compressed (see Fig. 4B). Here, the maximum compression length of the second connecting member 74 is X1.

Alternatively, when an external force is applied, the first rod 78 and the second rod 79 may be disposed by the casing 75 as long as the insertion coupling portion 77 of the second connection member 74 is drawn out of the casing 75. Slides toward the outside of the rod 78. The head 78a of each rod 78 and 79 presses the washers 83 and 86, respectively, so that the other ends of the rods 78 and 79 are The elastic members 81 and 82 which are supported are respectively compressed (see FIG. 4C). Here, the maximum tensile length of the second connecting member 74 is X2.

The difference between the third embodiment, the first embodiment, and the second embodiment is that in the first and second embodiments, the horizontal plate 10 has a shape in which the bottom surface and both sides of the beam B are wrapped. Directly fixed to the vertical plate 15 is also made of a shape surrounding the front and both sides of the pillar (P) is fixed directly to the pillar (P), in the third embodiment the horizontal plate 310 and the beam (B) There is a difference in that the vertical reinforcement 313 is provided between the bottom of the vertical plate 315 and the vertical reinforcement 317 between the front surface of the column (P).

That is, in the third embodiment, after reinforcing the bottom of the beam B using the horizontal reinforcement 313 having a predetermined thickness, the horizontal plate 310 on the plate is fixed to the bottom of the horizontal reinforcement 313. Also, after the front surface of the pillar P was reinforced using the vertical reinforcement 317 having a predetermined thickness, the vertical plate 315 on the plate was fixed to the front side of the vertical reinforcement 317.

At this time, the anti-vibration rubber pads 390 may be attached between the horizontal reinforcing hardware 313 and the horizontal plate 310, and between the vertical reinforcing hardware 317 and the vertical plate 315, respectively. The anti-vibration rubber pad 390 allows the horizontal plate 310 to adhere closely to the beam B (or the vertical plate 315 to the pillar P), and serves as a buffer between the members having different materials. Absorbs better to improve seismic performance.
