Abstract

<P>PROBLEM TO BE SOLVED: To provide a vibration control device which exerts a vibration control action by a simple mechanism, and to provide a building which is equipped with the vibration control device. <P>SOLUTION: This vibration control device acts as a resisting element for suppressing the shaking of the building 10, caused by earthquakes, by introducing tension into wire ropes 192, 193, 292 and 293 so as to apply rigidity to the building 10. Additionally, even if the building 10 is horizontally displaced by the earthquakes, either of linear blocks 152 of the vibration control devices 100 and 200 is bound to a foundation beam 12 (via a reinforcing foundation beam 60 joined to the foundation beam 12, in the case of this embodiment) by means of the wire ropes 193, 292 and 294. Thus, the linear block 152 is held in an original position without following the displacement of the building 10. In other words, the linear block 152 is horizontally displaced relatively to the building 10. Nevertheless, the vibrational energy of the relative displacement of the linear block 152 and the building 10 is damped by dampers 182 and 183. <P>COPYRIGHT: (C)2009,JPO&INPIT

  Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1A and 1B, a four-story building 10 includes five pillars 21, 22, 23, 24, 25, a ground level foundation beam 12 and four beams. 31, 32, 33, and 34. Note that the front side of the building 10 is the front side of the sheet of FIG. 1A and the left side of FIG. Further, in FIG. 1B and FIG. 2B to be described later, a hatched line representing a cross section is omitted in order to avoid complication of the drawing.

  A first reinforcing beam 40 is joined to the front surface 34 </ b> A of the beam 34 between the column 22 and the column 24. The first reinforcing beam 40 is formed with hanging portions 42 and 43 that hang downward from both ends in the longitudinal direction (left and right direction in FIG. 1A). Similarly, the second reinforcing beam 50 is joined to the front surface 32 </ b> A of the beam 32 between the columns 22 and 24. The second reinforcing beam 50 is also formed with hanging portions 52 and 53 that hang downward from both ends in the longitudinal direction. Further, a reinforcing foundation beam 60 is joined to the front surface 12 </ b> A of the foundation beam 12.

  As shown in FIGS. 1 and 2, a rolling support 150 is attached to the lower surface 40 </ b> A of the central portion of the first reinforcing beam 40.

  As shown in FIG. 3, the rolling support 150 includes a linear block 152 having a circulation mechanism for ball bearings 156. The ball bearing 156 rolls on the rolling groove 160 provided in the linear rail 158 while circulating. That is, the linear block 152 slides on the linear rail 158 serving as a bearing. With such a configuration, in the rolling support 150, the linear block 152 moves horizontally with a very small frictional resistance. Moreover, since the rigidity in the vertical direction is high, it can be tolerated for a high compressive load and also to a high tensile load. The longitudinal direction of the linear rail 158, that is, the moving direction of the linear block 152 is the longitudinal direction of the first reinforcing beam 40 (the left-right direction in FIG. 1A).

  As shown in FIG. 2A, the damper 182 and the damper 183 are connected between the both side surfaces 152A, B of the linear block 152 and the inner surfaces 42A, 43B of the hanging portions 42, 43 of the first reinforcing beam 40. is doing.

  As shown in FIGS. 1 and 2, one end of a wire rope 192 is attached to the linear block 152 of the rolling bearing 150. As shown in FIG. 1, the wire rope 192 is slanted, and the other end is attached to the vicinity of the column 25 of the reinforcing foundation beam 60 (the right end portion in the figure). Furthermore, one end of a wire rope 193 is attached to the linear block 152 of the rolling bearing 150. Similarly, the wire rope 193 is stretched obliquely, and the other end is attached to the vicinity of the column 21 of the reinforcing foundation beam 60 (the left end portion in the figure).

  The other ends of the wire ropes 192 and 193 are attached in the vicinity of the columns 25 and 21 of the reinforcing foundation beam 60 in the present embodiment, but are not limited thereto. For example, a bracket (not shown) may be provided at the corners of the reinforcing foundation beam 60 and the columns 25 and 21 and attached to the bracket.

  And tension is introduced into the wire ropes 192 and 193 by connecting and attaching a turnbuckle or the like. Since the wire rope 192 and the wire rope 193 are stretched in opposite directions, the directions in which the wire rope 192 and the wire rope 193 pull the linear block 152 are opposite to each other (horizontal direction).

  As shown in FIGS. 1A and 1B, a rolling bearing 151 is also attached to the lower surface 50A of the center portion of the second reinforcing beam 50. Since the rolling bearing 151 has the same configuration as the rolling bearing 150, the description thereof is omitted.

  A damper 184 and a damper 184 are connected between both side surfaces 152A, B of the linear block 152 and inner side surfaces 52A, 53B of the hanging portions 52, 53 of the second reinforcing beam 50. One end of a wire rope 292 is attached to the linear block 152 of the rolling support 151. The other end of the wire rope 292 is attached in the vicinity of the column 24 of the reinforcing foundation beam 60. Furthermore, one end of a wire rope 293 is attached to the linear block 152. The other end of the wire rope 293 is attached in the vicinity of the column 22 of the reinforcing foundation beam 60. And tension is introduced into the wire ropes 292 and 293 by connecting and attaching a turnbuckle or the like. Since the wire rope 292 and the wire rope 293 are stretched in opposite directions, the directions in which the wire rope 292 and the wire rope 293 pull the linear block 152 are opposite to each other (horizontal direction).

  In addition, although the other end of the wire ropes 292 and 293 is attached to the vicinity of the pillars 24 and 22 of the reinforcement foundation beam 60 in this embodiment, it is not limited to this. For example, a bracket (not shown) may be provided at the corners of the reinforcing foundation beam 60 and the columns 24 and 22 and attached to the bracket.

  The linear block 152 of the rolling bearing 150 and the linear block 152 of the rolling bearing 151 are configured to be restrained by the foundation beam 12 via the reinforcing foundation beam 60 by wire ropes 192, 193, 292, and 293.

  The vibration damping device 100 includes a rolling support 150, a pair of dampers 182 and 183, and a pair of wire ropes 192 and 193. Further, the vibration damping device 200 includes a rolling bearing 151, a pair of dampers 184 and 185, and a pair of wire ropes 292 and 293 as constituent elements.

  In the present embodiment, the building 10 is provided with two vibration control devices, the vibration control device 100 and the vibration control device 200, but the present invention is not limited to this. Only one of the vibration damping device 100 and the vibration damping device 200 may be provided. Or the structure provided with three or more damping devices may be sufficient.

  Further, the type of the dampers 182, 183, 184, 185 is not limited, but in the present embodiment, an oil damper is used.

  In the above embodiment, the wire ropes 192, 193, 292, and 293 are used as the linear members, but the present invention is not limited to this. For example, a PC steel rod may be used.

  Next, the operation of this embodiment will be described.

  By introducing tension to the wire ropes 192, 193, 292, 293, rigidity is imparted to the building 10 and acts as a resistance element that suppresses the shaking of the building 10 due to an earthquake.

  Furthermore, as indicated by imaginary lines in FIG. 4, even if the building 10 is horizontally displaced due to an earthquake, the linear blocks 152 of the vibration damping device 100 and the vibration damping device 200 are both based on the wire ropes 193, 292, and 294. The linear block 152 follows the displacement of the building 10 (beams 34 and 33) because it is constrained by the beam 12 (in this embodiment, via the reinforcing foundation beam 60 joined to the foundation beam 12). Stay in place without. That is, the linear block 152 is displaced in the horizontal direction relative to the building 10 (beams 34 and 33) and vibrates left and right.

  However, the vibration energy that the linear block 152 vibrates to the left and right is attenuated by the dampers 182, 183, 184, and 185. That is, the vibration energy that deforms the building 10 in the horizontal direction is attenuated by the dampers 182, 183, 184, and 185 to control the vibration. Therefore, since the seismic energy is absorbed by the dampers 182, 183, 184, and 185, the seismic force acting on the building 10 is reduced.

  In the case of FIG. 4, the distance between the linear block 152 and the hanging part 42 of the first reinforcing beam 40 and the hanging part 52 of the second reinforcing beam 50 is widened, so that the dampers 181 and 183 extend. On the contrary, since the space | interval of the linear block 152 and the hanging part 43 of the 1st reinforcement beam 40 and the hanging part 53 of the 2nd reinforcement beam 5 becomes narrow, the dampers 182 and 184 contract. FIG. 4 shows the deformation of the building 10 extremely larger than actual.

  Furthermore, since the vibration damping devices 100 and 200 are attached across a plurality of floors (by skipping the interlayer (floor)), the amount of deformation of the dampers 182, 183, 184, and 185 increases. Therefore, a basic seismic isolation effect is obtained. Moreover, since a large damping constant can be given, the absorption of seismic energy is large (a high damping effect can be obtained). Details of this operation will be described later.

  Moreover, since tension | tensile_strength is introduce | transduced by the wire ropes 192,193,292,293, buckling is reduced unlike force transmission members, such as a steel brace. Furthermore, since the wire ropes 192, 193, 292, and 293 are thinner than a force transmission member such as a steel brace, the wire ropes 192, 193, 292, and 293 are excellent in design and can sufficiently ensure lighting.

  In addition, even if tension is introduced into the wire ropes 192, 193, 292, 293, the column (casing) does not bear an axial force, so the strength of the column does not decrease.

  Moreover, the structure which does not introduce | transduce tension | tensile_strength in wire rope 192,193,292,293 may be sufficient. In this case, it is effective only for tension (so-called unilateral). For example, in the case of FIG. 4, it acts only on the extension of the dampers 181 and 183.

  Further, the vibration damping devices 100 and 200 can be introduced into both existing and new buildings to improve the earthquake resistance.

  Next, the improvement of the damping effect by attaching the damping devices 100 and 200 across a plurality of floors (by skipping the interlayer (floor)) will be described.

  The analysis condition is a four-mass system shear model, and the eigenvalue analysis is performed by changing the arrangement of the damper. FIG. 5 is a diagram showing this analysis model. TYPE-1 is a model in the case where a damping device (damper) is installed in each layer. TYPE-2-1 and TYPE-2-2 are models when a damping device (damper) is installed every other layer. TYPE-3 is a model when a vibration damping device (damper) is installed in each of the two layers. Further, the table of FIG. 6 shows the specifications of the analysis model.

  The analysis results of such an analysis model are shown in the table in FIG. 7A and the table in FIG. 7A shows the natural circular frequency ω0 (the period T of the building obtained from the eigenvalue), and the table in FIG. 7B shows the viscous damping constant h0 (contains the behavior when the building is shaken). ). In addition, MODE in each table | surface has shown the primary mode, the secondary mode, the tertiary mode, and the 4th mode.

  As can be seen from these tables, it is better to install the damping device (damper) on each layer (floor) than on each layer (floor). You can see that you can make it bigger. Since the vibration system is mainly the primary mode, the greater the primary viscous damping constant is, the more seismic energy is absorbed. In other words, rather than installing a vibration control device (damper) on each layer (floor), it is possible to obtain a higher vibration suppression effect by installing the straddle across the floor (by skipping the layer (floor)). Performance can be improved.

  Next, a second embodiment of the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the member similar to 1st embodiment, and the overlapping description is abbreviate | omitted.

  As shown in FIG. 8A, the four-story building 310 includes five pillars 321, 322, 323, 324, 325, a ground level foundation beam 312 (see FIG. 8B), and four columns. It is constructed with beams 331, 332, 333 and 334. Note that the front side of the building 310 is the front side in FIG. 8A and the left side in FIG. 8B. FIG. 8B is a side view of the front portion of the building.

  A reinforcing foundation beam 360 is joined to the front surface 312A of the foundation beam 312. A reinforcing beam 340 is joined to the front surface 334 </ b> A of the beam 334.

  A mounting member 361 having a substantially rectangular parallelepiped shape is joined to the central portion in FIG. 8A on the upper surface of the reinforcing foundation beam 360. A rolling support 350 is attached to the upper surface of the reinforcing foundation beam 360 on the left side of the attachment member 361 in the drawing. A rolling bearing 351 is attached to the upper surface of the reinforcing foundation beam 360 on the right side of the attachment member 361 in the drawing. Since the rolling bearings 350 and 351 have the same configuration as the rolling bearings 150 and 151 described in the first embodiment, the description thereof is omitted.

  A damper 382 is connected between the side surface 152A of the linear block 152 of the rolling bearing 350 and the inner side surface 361A of the mounting member 361. Similarly, a damper 383 is connected between the linear block 152B of the rolling bearing 351 and the inner surface 361B of the mounting member 361.

  One end of a wire rope 392 is attached to the linear block 152 of the rolling support 350. The other end of the wire rope 392 is attached to an attachment portion 334M provided at the center of the lower surface 340A of the reinforcing beam 340. Similarly, one end of a wire rope 393 is attached to the linear block 152 of the rolling bearing 351. The other end of the wire rope 293 is attached to an attachment portion 334M to which the other end of the wire rope 392 is attached.

  A tension is introduced into the wire ropes 392 and 393 by connecting and attaching a turnbuckle or the like. Even if tension is introduced, the linear blocks 152 of the rolling bearings 350 and 351 are stopped at a position balanced with the pressing force from the dampers 382 and 383.

  Thus, the linear block 152 of the rolling bearing 350 and the linear block 152 of the rolling bearing 351 are constrained to the beam 334 by the wire ropes 392 and 393.

  The vibration damping device 300 includes rolling bearings 350 and 351, dampers 382 and 383, and wire ropes 392 and 393 as constituent elements.

  In addition, in the said embodiment, although the wire ropes 392 and 393 are used as a linear member, it is not limited to this. For example, a PC steel rod may be used.

  Next, the operation of this embodiment will be described.

  By introducing tension into the wire ropes 392 and 393, the building 310 is given rigidity and acts as a resistance element that suppresses the shaking of the building 310 due to an earthquake.

  Further, as shown by an imaginary line in FIG. 9, when the beam 334 of the building 310 is horizontally displaced to the left side due to the earthquake, the linear block 152 of the rolling support 351 of the vibration damping device 300 is pulled to the left side in the drawing by the wire rope 393. (See arrow Y1 in the figure). Note that the linear block 152 of the rolling bearing 350 also moves to the left (see arrow Y2 in the figure). Although illustration is omitted, when the beam 334 of the building 310 is horizontally displaced due to an earthquake, the linear block 152 of the rolling support 350 of the vibration damping device 300 is pulled to the right side in the drawing by the wire rope 392 and moves to the right side. Note that the linear block 152 of the rolling bearing 351 also moves to the right. That is, when the beam 334 of the building 310 is horizontally displaced due to the earthquake, the linear block 152 also vibrates left and right. Note that FIG. 9 shows the deformation of the building 310 extremely larger than actual.

  However, vibration energy that causes the linear block 152 to vibrate left and right is attenuated by the dampers 382 and 383. That is, the vibration energy that deforms the building 310 in the horizontal direction is damped by the dampers 382 and 383 to be damped. Therefore, since the seismic energy is absorbed by the dampers 382 and 383, the seismic force acting on the building 310 is reduced.

  Furthermore, since the vibration damping device 300 is attached across a plurality of floors (by skipping layers (floors)), the amount of deformation of the dampers 382 and 383 increases. Therefore, a basic seismic isolation effect is obtained. Moreover, since a large damping constant can be given, the absorption of seismic energy is large (a high damping effect can be obtained). In addition, since the principle about this effect | action is the same as the content demonstrated in 1st embodiment, description is abbreviate | omitted.

  Further, since the tension is introduced by the wire ropes 392 and 393, buckling is reduced unlike a force transmission member such as a steel brace. Furthermore, since the wire ropes 392, 393, 292, and 293 are thinner than a force transmission member such as a steel brace, they are excellent in design and can sufficiently ensure lighting.

  In addition, even if tension is introduced into the wire ropes 392 and 393, the column (casing) does not bear an axial force, so the strength of the column does not decrease.

  Further, the vibration damping device 300 can be introduced into both existing and new buildings to improve earthquake resistance.

  In addition, it is good also as a structure provided with both the damping device 100,200 of 1st embodiment, and the damping device 300 of 2nd embodiment.

  In the above embodiment, the damping means for attenuating the vibration energy in the horizontal direction of the moving body is a damper, but is not limited thereto. For example, a configuration may be used in which a friction coefficient between a rolling bearing moving body (linear block) and a rail (linear rail) is increased and a friction damper (attenuating means) is functioned without providing a damper.

  In addition, the reinforcing strength and the joining method and the like of the reinforcing beam and the reinforcing foundation beam in the above embodiment are not particularly limited as long as the performance of the present invention can be exhibited.
