Description

  The present invention relates to a damping damper effect comparison and verification device, and more particularly to a damping damper effect comparison and verification device for explaining a mechanism in which a building having a damping structure absorbs vibration energy.

  A resonance phenomenon learning device that installs a building model with a damping structure on a shaking table, vibrates the shaking table to vibrate the building model with a damping structure, and learns the seismic performance of the building with the damping structure. It has been proposed (see Patent Document 1). The building model of the seismic control structure installed in this device consists of an elastic column, a floor material pinned to the elastic column, a roof pinned to the elastic column, and an additional weight suspended from the lower surface of the roof. It is composed of When the shaking table is vibrated in the horizontal direction, vibration energy is absorbed by shaking the additional mass, and shaking of the building model having a vibration control structure is suppressed. From this, it is possible to learn that a building with a seismic control structure is effective for earthquakes.

By the way, the structure is completely different between the damping structure of the building model installed on the shaking table and the damping structure of the actual building. For example, as an actual building seismic control structure, there is one that constitutes a brace-type seismic damper using a viscoelastic body. Therefore, when explaining to prospective home purchasers, etc., use the above equipment for the general structure of the seismic control structure, and for the actual structure of the seismic control structure, a partial model of the actual seismic control structure. And using catalogs. It is not realistic to vibrate a partial model of a full-scale damping structure.

  Next, embodiments of the invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing a schematic configuration of a damping damper effect comparison and verification apparatus according to a first embodiment of the present invention.

  With reference to FIG. 1, the damping damper effect comparison and verification device 20 is arranged on a box-shaped box 22, a rectangular plate-shaped diaphragm 23 installed on the box 22, and the diaphragm 23. Two installed building models 24 and 25 and two manual comparison units 26 and 27 attached to the front side surface of the box 22 are provided. Inside the box 22 is provided vibration means (not shown) that vibrates the diaphragm 23 in the left-right direction which is a predetermined horizontal direction (the arrow direction shown in FIG. 1). This vibration means generates vibration simulating an earthquake. Moreover, this vibration means can adjust a vibration period, can generate the vibration matched with the natural period of the predetermined building model, and can generate a resonance phenomenon in the building model. The building model 24 and the building model 25 are configured in the same shape, and both have a vibration control structure that forms brace type vibration control dampers 60 and 61. The manual comparison unit 26 and the manual comparison unit 27 are configured in the same shape. The difference is that a viscoelastic body is used for the building model 24 and the manual comparison unit 26, and an elastic body is used for the building model 25 and the manual comparison unit 27. A manual comparison unit 26 using a viscoelastic body is arranged in front of the building model 24 using the viscoelastic body, and the elastic body is used in front of the building model 25 using the elastic body. The manual comparison unit 27 is arranged.

  The vibration control damper 60 includes a first diagonal member 34, a second diagonal member 35, and a first connecting member 36 that connects the first diagonal member 34 and the second diagonal member 35. The first diagonal member 34, the second diagonal member 35, and the second connecting member 37 that connects the first diagonal member 34 and the second diagonal member 35 are provided. The manual comparison unit 26 includes a handle 38, a support plate 39, and a third connecting member 40 that connects the handle 38 and the support plate 39. The manual comparison unit 27 includes a handle 38, a support plate 39, and a handle. And a fourth connecting member 41 for connecting the support plate 39 and the support plate 39 to each other. A viscoelastic body is used for the first connecting member 36 and the third connecting member 40, and an elastic body is used for the second connecting member 37 and the fourth connecting member 41.

  The building model 24 includes a rectangular flat first floor 29, a rectangular flat second floor 30 disposed above the first floor 29, and a gable roof 31 disposed above the second floor 30. And pillars 28 arranged at the corners and connecting them. The first floor 29, the second floor 30, and the roof 31 are set to overlap with the same size in plan view. The pillar 28, the first floor 29, the second floor 30, and the roof 31 are fixedly connected by a fixture 32 such as a bolt. Between the first floor 29 and the second floor 30, the vibration control is performed along a line that bisects the first floor 29 in the front-rear direction (a direction orthogonal to the arrow direction shown in FIG. 1) in plan view. A damper panel 42 in which the damper 60 is incorporated is installed. Specifically, the damper panel 42 is positioned on two guides 33 attached to the upper surface of the first floor 29 and the lower surface of the second floor 30, respectively, and is fixed to the first floor by a fixing tool such as a mounting screw (not shown). It is fixed to the upper surface of the floor 29 and the lower surface of the second floor 30. The width of the damper panel 42 is set to be approximately the same as the width of the first floor 29 when viewed from the front. The pillar 28 is made of a flexible material and is formed in an elongated flat plate shape extending vertically, and is arranged so that a wide surface is peeled in the left-right direction. When the pillars 28 are arranged in this way, the pillars 28 are easily bent and deformed in the left-right direction, and hardly deformed in the front-rear direction. Therefore, the building model 24 is easily deformed in the left-right direction, hardly deformed in the front-rear direction, and can be deformed in the left-right direction. The first floor 29 is fixed to the diaphragm 23 by a fixing tool such as a bolt (not shown) so as to vibrate integrally with the diaphragm 23. The building model 25 has the same configuration as the building model 24 except that an elastic body is used for the second connecting member 37 of the vibration control damper 61 incorporated in the damper panel 43.

Explain the absorbed effects to those who plan to purchase a home. When the diaphragm 23 is vibrated, vibration energy of the same magnitude is given to the building model 24 and the building model 25, and the building model 24 and the building model 25 vibrate in the left-right direction. Both have the same structure and a vibration control structure, but the building model 24 and the building model 25 differ in the magnitude and manner of shaking. A person who intends to purchase a house visually grasps that the magnitude and manner of shaking differ between the viscoelastic body and the elastic body. In the manual comparison unit 26 and the manual comparison unit 27, when the handle 38 is moved to the same degree, the manual comparison unit 26 and the manual comparison unit 27 require the magnitude and deformation of the force required to move the handle 38 to the same degree. The speed of returning to the previous state is different. Home buyers directly experience the properties of viscoelastic bodies and elastic bodies.

  Next, the damper panel 42 will be described.

  FIG. 2 is a front view showing a schematic configuration of the damper panel shown in FIG. 1, FIG. 3 is a sectional view taken along the line II of FIG. 2, and FIG. It is sectional drawing of the II-II line shown in FIG.

The two damping dampers 60 arranged on the upper and lower sides have the same shape, although the positions where they are attached to the frame 44 are different. The left end of the damping damper 60 is connected to the frame 44 via a gusset plate 47 attached to the vertical frame 45 at the corner of the frame 44. The right end of the damping damper 60 is connected to the frame 44 via a gusset plate 48 attached to the middle portion of the vertical frame 45. Two damping dampers 60 are connected to the gusset plate 48. The vertical frame 45 and the horizontal frame 46 have a U-shaped cross section, are arranged so that the open surface is inward, and the respective ends are connected. The frame 44 is deformed so that the horizontal frame 46 on the upper surface of the paper moves while maintaining almost horizontal with respect to the outer side edge of each of the vertical frames 45 to form a parallelogram in a front view.

  The damping damper 60 includes a long and slender flat first diagonal member 34 and a second diagonal member 35, and a first connecting member 36 that connects the first diagonal member 34 and the second diagonal member 35. A circular hole is formed in the left end of the first diagonal member 34 on the paper surface, and a dry bearing 50 is inserted into the hole from both sides and attached. The first diagonal member 34 is centered on the axis of the stripper bolt 51 by inserting the stripper bolt 51 into a hole formed in the dry bearing 50 and the gusset plate 47 and screwing it into the nut 53 via the washer 52. The gusset plate 47 is pivotably attached. The second diagonal member 35 is also attached to the gusset plate 48 so that the end on the right side of the sheet is rotatable in the same manner as the first diagonal member 34 with the direction in which the stripper bolt 51 is inserted reversed. The gusset plate 47 and the gusset plate 48 are attached to the vertical frame 45 in contact with the inner surface of the vertical frame 45.

  The first diagonal member 34 and the second diagonal member 35 are set so that the end portions on the center side overlap each other by a predetermined length, and the surfaces of the first diagonal member 34 and the second diagonal member 35 facing each other are set. They are connected via a slide guide 56. The slide guide 56 includes a block 57 and a rail 58, and both slide in the longitudinal direction. A rail 58 is attached to the first diagonal member 34 and a block 57 is attached to the second diagonal member 35 so that the longitudinal direction thereof coincides with the longitudinal direction of the first diagonal member 34 and the second diagonal member 35. With such a configuration, the vibration damper 60 is extended and contracted while being regulated by the slide guide 56.

  Further, in front of the first diagonal member 34, the first diagonal member 34 and the second diagonal member 35 are connected via a first connecting member 36. An upper holding member 54 is attached to the upper surface on the center side of the first diagonal member 34, and a lower holding member 55 is attached to the lower surface on the central side of the second diagonal member 35. The upper holding member 54 and the lower holding member 55 are formed with hook portions that are substantially J-shaped when viewed from the front. A portion of the lower holding member 55 that contacts the second diagonal member 35 is configured in a bowl shape in a cross-sectional view, and the lower surface of the first diagonal member 34 when the first diagonal member 34 and the second diagonal member 35 slide. And the upper surface of the lower holding member 55 do not interfere with each other. The first connecting member 36 is a rectangular flat plate viscoelastic body that is disposed along the longitudinal flat center line of the rectangular flat plate 49 and the plate 49 that are disposed so as to face each other. It consists of viscoelastic rubber 62 and has a cross-section inverted H shape. The plate 49 of the first connecting member 36 is fitted in the groove of the hooking portion formed in the upper holding member 54 and the lower holding member 55 from the front-rear direction (direction penetrating the paper surface of FIG. 2). In this way, the first connecting member 36 is attached to the vibration damping damper 60, and the first connecting member 36 is detachable from the vibration damping damper 60.

  The damper panel 43 attached to the building model 25 has the same configuration as the damper panel 42 except that an elastic body is used for the second connecting member 37 of the vibration damper 61. As shown in FIG. 2, the second connecting member 37 has the same shape as the first connecting member 36, and includes a pair of plates 49 and 49 and an elastic rubber 63 that is an elastic body connecting them. It is composed of

  Since the damper panels 42 and 43 are configured as described above, it is possible to confirm the magnitude and manner of shaking in the building models 24 and 25 having the damping dampers that are close to the actual damping structure of the building. it can.

  Next, the manual comparison unit 26 will be described.

  4 is a front view showing a schematic configuration of the manual comparison unit shown in FIG. 1, FIG. 5 is a plan view showing a schematic configuration of the manual comparison unit shown in FIG. 1, and FIG. FIG. 6 is a sectional view taken along line VI-VI shown in FIG. 5.

  4, 5, and 6, the manual comparison unit 26 includes a rectangular flat plate back plate 65 attached to the box body 22 so as to extend along the side surface of the box body 22, and the back plate 65. A rectangular plate-like support plate 39 connected so as to extend forward from the upper part horizontally, and one corner from the rectangle connected at a predetermined interval so as to be orthogonal to the support plate 39 and the back plate 65. Two reinforcing plates 66 each having a large chamfer shape are provided. The reinforcing plate 66 is attached in order to prevent the support plate 39 from tilting forward when the support plate 39 receives a vertical load. Furthermore, the manual comparison unit 26 includes a handle 38, a third connecting member 40 that connects the handle 38 and the support plate 39, and a slide guide 71 that connects the handle 38 and the support plate 39.

  The handle 38 is a rod-shaped portion 76 having a rectangular shape with a rectangular cross section arranged with the longitudinal direction aligned with the left-right direction, and a columnar shape connected to both ends of the rod-shaped portion 76 with the axial direction aligned with the front-rear direction. And a columnar portion 75. The lower surface of the rod-shaped portion 76 and the upper surface of the support plate 39 are connected via a slide guide 71. The slide guide 71 includes a block 72 and a rail 73, and both slide in the longitudinal direction. A rail 58 is attached to the rod-like portion 76, and a block 57 is attached to the support plate 39 so that the longitudinal direction thereof coincides with the longitudinal direction of the rod-like portion 76. With this configuration, the handle 38 slides in the left-right direction while being regulated by the slide guide 71.

  Further, in front of the handle 38, the handle 38 and the support plate 39 are connected via a third connecting member 40. An upper holding member 67 is attached to the center front side surface of the rod-like portion 76 of the handle 38, and a lower holding member 68 is attached to the center front side upper surface of the support plate 39. The upper holding member 67 and the lower holding member 68 have hook portions that are substantially U-shaped in plan view at both ends. A clearance is provided between the upper holding member 67 and the support plate 39 so that the lower surface of the upper holding member 67 and the upper surface of the support plate 39 do not interfere when the handle 38 slides. The third connecting member 40 is a rectangular flat plate-like plate 49 arranged so as to face the plate 49 and the plate 49 and a rectangular flat plate-like viscoelastic body arranged along the longitudinal center line and connecting them. It consists of viscoelastic rubber 62 and has a cross-section inverted H shape. A plate 49 of the third connecting member 40 is fitted into the groove of the hooking portion formed in the upper holding member 67 and the lower holding member 68 from the vertical direction (direction penetrating the paper surface of FIG. 5). In this way, the third connection member 40 is attached to the manual comparison unit 26, and the third connection member 40 is detachable from the manual comparison unit 26.

  A square columnar projecting member 69 projecting rearward is attached to the central back side surface of the rod-shaped portion 76 of the handle 38. On the other hand, on the upper surface of the support plate 39, rectangular columnar stopper members 70 and 70 are erected so as to sandwich the protruding member 69 from the left and right sides with a predetermined interval. Thus, even if the handle 38 tries to slide beyond the range restricted by the slide guide 71, the protruding member 69 contacts the stopper member 70, and the handle 38 slides beyond the predetermined range. It is supposed not to. Therefore, when the third connecting member is removed from the manual comparison unit 26, it is possible to prevent the handle 38 from sliding off the manual comparison unit 26.

  The manual comparison unit 27 attached in front of the building model 25 has the same configuration as the manual comparison unit 26 except that an elastic body is used for the fourth connecting member 41. As shown in FIG. 5, the fourth connecting member 41 has the same shape as the third connecting member 40, and includes a pair of plates 49 and 49 and an elastic rubber 63 that is an elastic body connecting them. It is composed of Further, the first connecting member 36 and the third connecting member 40 have the same shape, and the second connecting member 37 and the fourth connecting member 41 have the same shape. Therefore, in the building models 24 and 25 and the manual comparison units 26 and 27, the first connecting member 36, the second connecting member 37, the third connecting member 40, and the fourth connecting member 41 can be interchanged. Yes.

  Since the manual comparison units 26 and 27 are configured in the same manner as described above, it is possible to confirm the difference in hardness and deformation mode of the viscoelastic rubber 62 and the elastic rubber 63 while directly feeling them.

  Next, a state where the building model 24 vibrates and the damper panel 42 is deformed will be described.

  FIG. 7 is a front view showing a state where the damper panel shown in FIG. 1 is deformed, and corresponds to FIG.

  With reference to FIG. 7, the deformation | transformation state of the damper panel 42 when the building model 24 deform | transforms rightward is shown. The entire frame 44 of the damper panel 42 is deformed into a parallelogram in front view. The vertical frames 45 and 45 are inclined in the direction indicated by the arrows in FIG. 7 with the lower outer edges of the vertical frames 45 and 45 as fulcrums. The upper horizontal frame 46 moves in the direction indicated by the arrow in FIG. 7 with the upper outer edges of the vertical frames 45 and 45 as fulcrums while maintaining substantially horizontal. In the state in which the frame 44 is deformed in this way, the lower damping damper 60 receives a pulling force, so that it extends while deforming the viscoelastic rubber 62 into a parallelogram in front view, and the upper damping damper 60 In order to receive the compression force, the viscoelastic rubber 62 is contracted while being deformed into a parallelogram in front view. At this time, the block 57 and the rail 58 of the slide guide 56 are also slid according to the expansion and contraction of each of the damping dampers 60. Since the vibration damper 60 is restricted by the slide guide 56 and expands and contracts, the straight state is maintained without being bent at the connecting portion between the first diagonal member 34 and the second diagonal member 35. As the vertical frames 45 and 45 are inclined, the gusset plate 47 and the gusset plate 48 are also inclined. Each of the damping dampers 60 is rotated with respect to the inclined gusset plate 47 and the gusset plate 48 around the axis of the stripper bolt 51. When the damper panel 42 is deformed by receiving a force in a direction opposite to the direction indicated by the arrow in FIG. It will grow to receive power. The damper panel 43 incorporating the damping damper 61 in which the elastic rubber 63 is used also has different deformation amounts and deformation speeds when the same vibration energy is applied, but is configured in the same shape, so that the damper panel 42 is configured. Deforms in the same way.

  Next, a state in which the manual comparison unit 26 is deformed by manually moving the handle 38 will be described.

  FIG. 8 is a plan view showing a state in which the manual comparison unit shown in FIG. 1 is deformed, and corresponds to FIG.

  Referring to FIG. 8, the handle 38 is moved with a predetermined force in the direction of the arrow shown in FIG. The viscoelastic rubber 62 of the third connecting member is deformed into a parallelogram in plan view. As the block 72 fixed to the support plate 39 slides on the rail 73, the handle 38 is moved while the direction of movement to the slide guide 71 is restricted. The handle 38 can be similarly moved in the direction opposite to the direction of the arrow shown in FIG. Although the deformation amount and the deformation speed are different, the manual comparison unit 27 using the elastic rubber 63 can be deformed in the same manner as the manual comparison unit 26. A person who intends to purchase a home or the like moves the grips 38 of the manual comparison unit 26 and the manual comparison unit 27 with the same level of force or the same level of movement, so that the viscoelastic rubber 62 and the elastic rubber 63 are moved. Differences in hardness and deformation modes can be confirmed while experiencing directly. When the handles 38 of the manual comparison unit 26 and the manual comparison unit 27 are moved to the same extent, the manual comparison unit 26 using the viscoelastic rubber 62 is compared with the manual comparison unit 27 using the elastic rubber 63. Is slowly restored to its pre-deformation state due to the viscosity of the viscoelastic rubber 62. The manual comparison unit 27 using the elastic rubber 63 instantaneously returns to the state before the deformation by the action of the spring of the elastic rubber 63.

  Next, vibration modes of the building model 24 and the building model 25 will be described.

  FIG. 9 is a front view schematically showing a state where the building model shown in FIG. 1 is vibrating.

  Referring to FIG. 9, when vibration plate 23 is vibrated in the direction of the arrow shown in FIG. 9, the same vibration energy is given to building model 24 and building model 25. The building model 24 and the building model 25 vibrate while shaking from side to side, as indicated by the two-dot chain line in FIG. However, the swinging width of the building model 24 using the viscoelastic rubber 62 is smaller than that of the building model 25 using the elastic rubber 63 due to the stickiness of the viscoelastic rubber 62. Since the building model 24 and the building model 25 are configured in the same shape, it can be seen that the vibration energy is absorbed by the viscoelastic rubber 62.

From the above, in the vibration damping damper effect comparison / verification apparatus 20, in the building models 24 and 25 having the vibration damping dampers 60 and 61 that are close to the actual structure of the vibration damping structure of the building, how the building models 24 and 25 are swayed visually. Can be confirmed. And, it is easy to grasp that a building such as a vibration control structure having a brace type vibration control damper using the viscoelastic rubber 62 absorbs vibration energy generated from the earthquake and suppresses the shaking of the building. it can. Moreover, since the building models 24 and 25 have a vibration control structure close to the real thing, the structure of the vibration control structure having the brace type vibration control damper 60 using the viscoelastic body and the viscoelastic rubber 62 absorb vibration energy. It is possible to easily grasp that it is absorbed.
Furthermore, if the first connecting member 36 and the second connecting member 37 are exchanged between the building models 24 and 25, the way the two building models 24 and 25 are shaken when the diaphragm 23 is vibrated is also changed. It can be confirmed that there is no difference in the shaking of the building model by portions other than the elastic rubber 62 and the elastic rubber 63.

  Further, when the third connecting member 40 and the fourth connecting member 41 are exchanged between the manual comparison units 26 and 27, two manual operations when the respective handles 38 of the manual comparison units 26 and 27 are moved to the same extent. Since the speed at which the comparison portions 26 and 27 return to the state before the deformation is also switched, the speed at which the manual comparison portions 26 and 27 return to the state before the deformation by the portions other than the viscoelastic rubber 62 and the elastic rubber 63 is not different. Can be confirmed.

  Furthermore, since the 1st connection member 36 and the 3rd connection member 40 can be replaced, and the 2nd connection member 37 and the 4th connection member 41 can be replaced, the viscoelasticity experienced by the manual comparison parts 26 and 27 is experienced. The vibration of the building models 24 and 25 can be confirmed using the rubber 62 and the elastic rubber 63. Therefore, it can be reliably confirmed that the viscoelastic rubber 62 absorbs vibration energy.

  In the above embodiment, the two building models and the two manual comparison units are configured in the same shape. However, the viscoelastic rubber and the elastic rubber are used to swing the building model and the manual comparison unit is deformed. As long as it can be confirmed that the modes are different, the shapes may be slightly different, and the shapes may be almost the same.

  In the above embodiment, two seismic dampers are used for one building model. However, it is not always necessary to have such a configuration, and one or three or more building dampers are required for one building model. Damping dampers may be used.

  Furthermore, in the above-described embodiment, the vibration dampers arranged vertically are configured in the same shape. However, if the parts configuration of the vibration damper is the same, for example, the length of the vibration damper disposed vertically is long. The shape may be different.

  Furthermore, in the above-described embodiment, the building model is configured in the above shape, but may have other shapes as long as the difference in swinging method can be confirmed between the viscoelastic rubber and the elastic rubber.

  Further, in the above embodiment, the manual comparison unit is configured in the above shape, but includes a handle, a support plate, a connecting member for connecting the handle and the support plate, and viscoelastic rubber and elastic rubber. Other shapes may be used as long as differences in hardness and deformation modes can be confirmed.
