Vibration control damper using interstory drift of rahmen frame}

The present invention relates to a damping damper using the interlaminar deformation of a ramen frame. Particularly, the present invention relates to a damping damper that can absorb and attenuate a horizontal load by using an interlaminar deformation that occurs when a horizontal load acts on a ramen frame structure in which columns and beams are rigid. A damping damper using an interlaminar deformation.

Recently, with the spread of concerns about earthquake damage, seismic design of buildings and bridges has attracted attention. Seismic design is a comprehensive construction method to protect various structures from the impact of earthquake, and if it is classified in detail, it can be divided into seismic design, vibration suppression, and seismic design.

First of all, the seismic design includes a seismic design and a vibration damping design in a broad sense. However, if the meaning is narrowed down, it can be explained only by the design technique that overcomes the earthquake load through the strength of the structure itself. This seismic design increases the strength and toughness of various members constituting the structure, thereby increasing the rigidity of the structure itself, thereby maintaining structural stability and usability of the structure from earthquake loads.

However, in the seismic design, since a member having a large cross section is used to increase the strength and toughness of the member constituting the structure, or a lot of rebar is consumed, the quantity is increased and economic efficiency is lowered. In particular, earthquake-resistant performance is being questioned in overseas cases where earthquake-resistant structures are collapsed by earthquakes.

In comparison with such a seismic design, the damping and seismic design is an advanced technology for reinforcing the economic performance and the seismic performance by the existing seismic design, and its use has recently been increased.

Among these, the vibration suppression design is a structure for dissipating the seismic load applied to the structure. That is, it is a design method to reduce the earthquake load by artificially adjusting the frequency of the structure according to the vibration characteristics of the seismic wave to prevent the resonance of the structure and further canceling the vibration of the structure and the vibration of the seismic wave.

Hydraulic dampers or steel dampers are used to apply the damping design described above to steel structures or concrete structures.

Hydraulic dampers have superior seismic performance compared to steel dampers and are mainly used in Japan, where heavy and heavy earthquakes occur frequently throughout the country. However, since these hydraulic dampers are expensive, they are excessively unnecessary in Korea, where the frequency of earthquakes is low and the strength of earthquakes is not high. On the other hand, steel dampers are used for reinforcing steel structures because the damping performance is somewhat lower than hydraulic dampers, but the construction cost is low.

However, the damping structure using the above-mentioned steel damper is a type of brace (BRACE) type most of the spatial obstacles are not suitable for the variable structure, there is a disadvantage that the replacement after the earthquake is cumbersome. Therefore, it is difficult to apply to the vibration suppression structure of the RC structure of the variable structure, and it is inefficient to reinstall the vibration suppression device after the earthquake.

Therefore, it is possible to solve the problems of the vibration damping structure using the above-mentioned hydraulic damper and the vibration damping structure using the steel damper, that is, the economical and spatial obstacles, and the necessity of a new damping damper which can obtain the optimum seismic control effect at a reasonable cost. This situation is desperately required.

Preferably, a rolled steel having a cross-sectional shape of type I or H, which can be easily obtained, the mechanical properties of the material are well known and uniform quality can be used. For example, the upper horizontal member 12 may be integrally combined with the upper beam 2a through the mortar adhesive 3 and the first and second studs 4 and 5, as shown in FIG. 5. The lower horizontal member 14 may also be integrally synthesized in the same manner as the upper horizontal member 12.

One end of the vertical member 40 is fixed to the upper connecting plate 32 through the fastening coupling of the bolt 42 and the other end is fixed to the lower connecting plate 34 through the fastening coupling of the bolt 44. The vertical member 40 may be a rolled steel having a cross-sectional shape of the I-type or H-type like the horizontal members (12,14).

A plurality of friction pads 50 arranged in a circumference are interposed between the upper friction plate 22 and the upper connecting plate 32 and between the lower friction plate 24 and the lower connecting plate 34. It is. The friction pad 50 is an aluminum composite material in which ceramic particles are dispersed and reinforced in aluminum or an aluminum alloy, a carbon-carbon composite material, a semi-metallic friction material using metal fiber, metal fiber and oil. ㆍ It can be made of any one of low-steel friction materials using mixed non-machined fibers and non-steel friction materials using only organic / inorganic fibers without using any metal fibers.

The fastening bolt 60 is inserted into the slot holes 22a and 24a and then screwed and fixed to the nut 62 at the upper and lower horizontal members 12 and 14. Therefore, the friction pad 50 is forcibly in close contact with the upper and lower friction plates 22 and 24 by the screw tightening force of the fastening bolt 60.

The friction pad 50 is positioned between the first and second row slot holes 22a and 24a arranged in two rows of circumferences as shown in FIGS. 4A and 4B, and the friction pad 50 is connected to the upper and lower parts.

Hereinafter, the operation of the damping damper according to the first embodiment configured as described above will be described.

When earthquake loads are transmitted to the ramen framed structures, interlaminar deformation occurs in columns 1 and beams 2a and 2b. Due to this interlayer deformation, the upper beams 2a and the lower beams 2b are displaced in opposite directions, and the upper and lower horizontal members 12 and 14 fixed to the upper beams 2a and the lower beams 2b. As an example, as shown by the arrow in FIG. 1, the motors move in opposite directions V1 and V2.

In this case, when the upper and lower horizontal members 12 and 14 move in opposite directions, rotational forces are generated in the upper and lower connecting plates 32 and 34 connecting the upper horizontal member 12 and the lower horizontal member 14. do. That is, the upper and lower connecting plates 32 and 34 are rotated in a clockwise direction in FIG. 1 while maintaining a straight line through the vertical member 40. Therefore, the upper friction plate 22 and the lower friction plate 24 are slid and rotated simultaneously with the friction pads 50 installed on the upper and lower connection plates 32 and 34.

As such, when the upper friction plate 22 and the lower friction plate 24 are slid and rotated, the fastening bolt 60 is guided from the slot holes 22a and 24a to move from the position of FIG. 4A to the position of FIG. 4B. Thereafter, frictional resistance is generated between the friction pad 50 and the upper and lower friction plates 22 and 24, and the seismic load is absorbed and damped through the frictional resistance, thereby ensuring structural stability and usability of the frame structure. do.

Since the damping damper of the first embodiment is a multi-point surface contact method using a plurality of friction pads 50 of relatively small size, the earthquake load can be efficiently reduced or eliminated. In particular, the structure is simple, easy to manufacture and install, and low cost can greatly contribute to productivity improvement.

Second Embodiment

The same parts as in the first embodiment are described below using the same reference numerals, and repeated descriptions are omitted as much as possible.

A second embodiment of the present invention is shown in Figures 6-10. The second embodiment is characterized in that the seismic load is absorbed and damped at the intermediate portion of the column 1.

As shown in FIG. 6, the upper and lower horizontal members 12 and 14 having the same I-shaped or H-shaped cross section as the first embodiment are fixed to the upper beam 2a and the lower beam 2b, respectively, and the upper and lower horizontal beams are fixed. The members 12 and 14 behave integrally with the upper beams 2a and the lower beams 2b.

An upper vertical member 40a is connected and fixed to the upper horizontal members 12 and 14, and a lower vertical member 40b is connected and fixed to the lower horizontal member 14, and these upper and lower vertical members 40a and 40b are fixed. ) Are arranged in a straight line in the longitudinal direction of the column 1 at regular intervals. At this time, the upper and lower vertical members (40a, 40b) are positioned in a state separated from the pillar (1). The upper and lower vertical members 40a and 40b may be made of rolled steel having a cross-sectional shape of I or H shape.

The friction plate 120 of FIG. 7 is mounted at either end of the upper and lower vertical members 40a and 40b facing each other. In this embodiment, the friction plate 120 is installed on the upper vertical member 40a as shown in FIG. 7, but may be installed on the lower vertical members 40a and 40b.

The friction plate 120 is made of the same material as the upper and lower friction plates 22 and 24 of the first embodiment. The friction plate 120 is formed with a plurality of slot holes 120a. The slot holes 120a may be arranged in a plurality of rows in the horizontal direction and the vertical direction, respectively.

The friction plate 120 and the lower vertical member 40b are connected to each other via the connection plate 130 of FIG. 8. The connecting plate 130 is disposed so that the upper portion thereof faces the friction plate 120 as shown in FIG. 10, and the lower portion thereof is fixed to the lower vertical member 40b by a bolt 42.

In the present embodiment, the friction pad 50 is fitted into the plurality of friction pad mounting grooves 130a so as to be positioned between the two adjacent upper and lower side slot holes 120a in the longitudinal direction. Therefore, the friction pad 50 behaves integrally with the connecting plate 130. The friction pad 50 is made of the same material as that of the first embodiment.

The connecting plate 130 is connected to the friction plate 120 by a plurality of fastening bolts 60. The fastening bolt 60 is assembled to the bolt through hole 130b of the connecting plate 130 and inserted into the slot hole 120a, and then screwed by the nut 62. Therefore, the fastening bolt 60 is movable in the section allowed by the long hole of the slot hole 120a, the friction pad 50 is forcibly in close contact with the friction plate 120 by the screw tightening force of the fastening bolt 60.

Hereinafter, the operation of the damping damper according to the second embodiment configured as described above will be described.

When an earthquake load acts on the ramen frame structure of FIG. 6, interlayer deformation occurs in the columns 1 and the beams 2a and 2b.

Move in opposite directions.

In this case, when the upper and lower horizontal members 12 and 14 move in opposite directions, the upper and lower vertical members 40a and 40b connected to the upper horizontal member 12 and the lower horizontal member 14 are also slot holes 120a. Are guided within the allowable section and move in opposite directions. At the same time, the friction plate 120 and the connecting plate 130 also move in opposite directions. Here, the friction pad 50 may be described as moving to the dashed-dotted position in FIG. 9.

As such, since the friction plate 120 and the connecting plate 130 move in opposite directions to each other, frictional resistance is generated between the friction plate 120 and the friction pad 50, and the seismic load is absorbed and damped using the frictional resistance. As a result, structural stability and usability of the frame structure are ensured.

Since the damping damper of the second embodiment is a multi-point surface contact method using a plurality of friction pads 50 having a relatively small size, the earthquake load can be effectively reduced or eliminated. In particular, the structure is simple, easy to manufacture and install, and low cost can greatly contribute to the productivity.

Also in the second embodiment, the number of the friction pad 50 and the friction pad mounting groove 130a can be increased or decreased according to the magnitude of the earthquake load, and the shape of the friction pad 50 changes the friction area. It is not limited to the drawings shown, of course, various changes are possible. In addition, even if the friction plate 120 is installed on the lower vertical member 40b, and the reverse position of the connecting plate 130 is reversely installed, the same vibration damping effect can be obtained.

On the other hand, in the embodiment of the present invention has been described by configuring a damping damper on the front of the column and the beam, the present invention may be of the same structure on both sides, as well as the rear of the column and the beam.

The damping damper described above is a friction type damping damper which operates by the interlaminar deformation of the ramen frame generated by the seismic load and absorbs and damps the seismic load by the frictional resistance between the friction pad and the friction plate. The present invention relates to an elastic damping damper that absorbs and attenuates horizontal loads by using microscopic deformation due to wind loads as well as seismic loads. The elastic damping damper is also divided into two embodiments according to the position of absorbing and damping the horizontal load in the same manner as the friction damping damper. In the following, the same reference numerals are used for the same elements as the above-described embodiments, and repeated descriptions will be omitted for the convenience of description.
