Description

  The present invention relates to a vibration control panel model and a vibration suppression behavior explanation device that can explain the vibration control behavior of a vibration control building against an earthquake.

  Regarding the earthquake resistance of buildings, there are technically earthquake-resistant structures, seismic structures, and seismic isolation structures, but it is difficult to explain these characteristics in words to those who do not have expertise in building structures. There are various models for explanation. These models include a frame structure model in which the column beams are made of spring plates, a pin brace structure model in which the brace is expressed by rubber, etc., a tuned damper such as TMD, for example, a damper that uses a pendulum damper. A structural model has been proposed. These are not damping device models that use energy absorbers. In addition, seismic isolation models with rollers and springs in the base have been proposed.

  For example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2004-184600) describes a model of a seismic wall structure using a structural member (connecting member) that absorbs energy. It is described that the energy absorbing action is explained by deforming and visually observing the deformed state.

  Non-patent document 1 describes a model of an earthquake-resistant structure, and describes a house model that explains the effect of earthquake-resistant reinforcement depending on the presence or absence of bracing.

  However, it is difficult to express the energy absorption mechanism, which is a characteristic of the energy absorber, about the seismic structure model using the energy absorber using energy absorption, and has no specialized knowledge. On the other hand, no model has been proposed for explaining the damping structure that shows the dynamic behavior and damping effect of the damping panel with energy absorption characteristics that can be easily explained.

  For example, in the model of Patent Document 1 (Japanese Patent Application Laid-Open No. 2004-184600), only the shape of the connecting member when a force is applied and the connecting member (energy absorber) is deformed, There is no explanation of how quickly the vibration will settle.

  The paper model of Non-Patent Document 1 can explain the effect of seismic reinforcement, but cannot explain the vibration control behavior of the building because it does not have an energy absorption mechanism.

  Therefore, the present invention has no expertise in vibration control behavior and vibration control performance of buildings using energy absorbers (attenuation of amplitude and time from when a force is applied to the building until the vibration starts to stop). Another object of the present invention is to provide a device for a vibration control panel model and a vibration suppression behavior explanation model that can be explained in an easy-to-understand manner.

  In order to solve the above problems, a first structure of a vibration control panel model according to the present invention is a vibration control panel model mounted in a building model capable of vibration, and the vibration control panel model is the vibration control panel model. An energy absorber that deforms in the surface direction and absorbs the vibration energy of the building model when deformed in the surface direction, and the energy absorber is a magnet sheet, and is divided so as to partially overlap each other. And at least one of the overlapping portions has the magnet sheet that attracts the other by magnetic force, and the overlapping portions slide and friction with each other in the surface direction.

In addition, the second configuration of the vibration control panel model according to the present invention is a vibration control panel model mounted in a building model capable of vibration, and the vibration control panel model is deformed in the plane direction of the vibration control panel model. An energy absorber that absorbs the vibration energy of the building model by being deformed in a plane direction, and the energy absorber is an elastic sheet, and there are two overlapping portions so that they partially overlap each other The overlapping portions are divided so that the overlapping order of the overlapping portions is different from each other, the overlapping portions are brought into close contact with each other by the elasticity of the sheets, and sliding friction is caused in the surface direction at the overlapping portions. To do.

Moreover, the 1st structure of the vibration suppression behavior description apparatus which concerns on this invention has a building model which can vibrate, and attaches the damping panel model in any one of the said 1st- 3rd in the building model It is characterized by that.

  Further, a second configuration of the vibration suppression behavior explanation device according to the present invention is the vibration suppression behavior explanation device of the first configuration, wherein the building model includes a plurality of horizontal members joined between the vertical members and the vertical members. It is made of material and can be vibrated.

Further, a third configuration of the vibration suppression behavior explanation device according to the present invention is the vibration suppression behavior explanation device of the second configuration, in which at least one of the joint portions of the longitudinal member and the cross member is an elastic joint. The other joint is a pin joint.

In addition, a fourth configuration of the vibration suppression behavior explanation device according to the present invention is characterized in that in the vibration suppression behavior explanation device of the second configuration, the vertical member and the cross member are made of paper.

Further, a fifth configuration of the vibration suppression behavior explanation device according to the present invention is the vibration suppression behavior explanation device of the first to fourth configurations, and has a ground model that can move or swing, and the building model is The lower part is fixed on the ground model, and the upper building model vibrates by movement or swinging of the ground model.

In the vibration damping behavior described device of the first to third configuration of the seismic control panel model and the first to fifth configurations, the building with energy absorber typified history damper damping behavior and damping performance ( Can explain easily to those who do not have expert knowledge on the amplitude attenuation and time from when a force is applied to a building and when the vibration starts to stop. In addition, if an energy absorber is attached to the building model, it can be compared how the damping performance changes before and after.

  Further, in the vibration control panel model having the first configuration, the parts that become the energy absorbers of the vibration control panel models that are divided so as to partially overlap each other due to the swing of the building model to which the vibration control panel model is attached are mutually connected. It is possible to experience a state in which energy is absorbed by sliding friction in the surface direction. Moreover, the energy absorber absorbs the vibration energy of the building model through a visually well-known operation of sliding friction of overlapping parts, so that the vibration suppression behavior and vibration suppression performance of the building can be explained in an easy-to-understand manner.

  Further, the vibration damping performance can be easily changed by changing the sliding friction area and magnetic force of the magnet sheet. In addition, the magnet sheet is easily available, and it is easy to obtain a sheet having the same performance such as magnetic force. Even if the performance such as magnetic force is different, it is possible to easily obtain an energy absorber that exhibits uniform vibration performance by adjusting the sliding friction area.

Moreover, in the vibration suppression behavior explanation apparatus of the 4th structure, the weight of a building model becomes light because the vertical member and the cross member of the building model were made of paper, and compared with a building model with a large mass in the case of the same amplitude. Vibration energy is reduced. Therefore, the vibration of the building model can be sufficiently damped only by energy absorption by the frictional force of the overlapping elastic sheets. In addition, the building model is even lighter and easier to carry, reducing production costs. It can also be distributed as a work set that can be easily worked at home, allowing the family to experience the vibration control performance while having fun.

FIG. 1 is a front view of a vibration suppression behavior explanation device according to the present embodiment. FIG. 2 is a configuration diagram of a vibration control panel model and a building model. FIG. 3 is a front view of the vibration suppression behavior explanation device in the use state. FIG. 4A is a front view of the vibration control panel model in use.

(Configuration of vibration suppression behavior explanation device 1)
First, the configuration of the vibration suppression behavior explanation device 1 will be described. As shown in FIG. 1, the vibration suppression behavior explanation device 1 has two building models 2, a vibration control panel model 3, a seismic panel model 21, a ground model 4, and a transparent case 13. It is a device that can explain the behavior.

  The building model 2 includes left and right vertical members 5 and four cross members 6 joined between the vertical members, and can vibrate left and right. The lower part of the building model 2 is fixed on the ground model 4. The building model 2 is a model of a three-story building, and a rectangular space surrounded by the vertical members 5 and the horizontal members 6 represents the space of each floor such as the first to third floors. The building model 2 is not limited to a three-story building, and may be a two-story or four-story model by providing a plurality of cross members. The bottom cross member 6 may also serve as the ground model 4.

  As shown in FIG. 2, the longitudinal member 5 is configured by a spring plate that is an elastic member. The cross member 6 is composed of a plate having almost no elasticity. The joint between the longitudinal member 5 and the transverse member 6 is rigidly joined. As a result, the building model 2 itself can smoothly swing left and right. It should be noted that at least one of the left and right vertical members 5 may be a spring plate that is an elastic member. Further, in order for the building model 2 to be self-supporting, it is only necessary that at least one of the joints between the longitudinal member 5 and the transverse member 6 is rigid and the other is joined with a pin.

  The vibration control panel model 3 is a model of a vibration control panel that absorbs vibration energy, and is divided into two frames 7 so as to partially overlap each other. The vibration control panel model 3 is provided with a magnet sheet 8 that attracts each other as an energy absorber to the overlapping portion and slides and frictions in the surface direction of the vibration control panel model 3. The magnet sheet 8 may be only one and the other may be a magnetic material sheet, and the magnetic material sheet may be attracted by the magnetic force of the magnet sheet 8. Here, the plane direction is a plane direction orthogonal to the thickness direction of the vibration control panel model 3.

  Specifically, the frame 7 forms two convex portions 7a and 7b, and the magnet sheet 8 is provided at the tips of the convex portions 7a and 7b. A ladder-like vibration control panel model 3 is formed by adhering the magnet sheets 8 so that the two frames 7 are symmetrical. And the seismic control panel model 3 is attached in one building model 2 by pin-joining four places of the upper-end lower end of the flame | frame 7 to the up-and-down horizontal member 6. FIG. The frame 7 is a rigid body and does not change its shape due to vibration such as an earthquake.

  The earthquake-resistant panel model 21 is a model of an earthquake-resistant panel, and the two frames 7 are symmetrical, and the tips of the convex portions 7a and 7b are connected by a rubber sheet 22 that is an elastic member. Is. This ladder-like seismic panel model 21 is mounted in the other building model 2 by pin-joining the upper and lower cross members 6 at four locations at the upper and lower ends of the frame 7.

  The ground model 4 is a model of the ground surface, and can move or swing left and right like an earthquake. The ground model 4 includes a plate 9, a spring 10, a string 11, and a stopper 12. A spring 10 is attached to the lower surface of the plate 9, and one end of the string 11 is attached to the plate 9. By pulling the other end of the string 11 rightward in the figure to move the plate 9 in the horizontal direction and releasing the other end, the plate 9 (ground model 4) swings left and right by the elastic force of the spring 10. A stopper 12 is fixed in the middle of the string 11, and a constant amount of initial amplitude is always given to the ground model 4 by pulling the string 11 to a position where the stopper 12 contacts the transparent case 13 containing the ground model 4. be able to.

(Operation of vibration suppression behavior explanation device 1)
Here, a method of using the vibration suppression behavior explanation device will be described. As shown in FIG. 3, by pulling and releasing the string 11, the ground model 4 is swung to transmit the vibration to the building model 2. When vibration is transmitted to the building model 2, the vertical member (spring plate) 5 bends to the left and right, and a rectangular space surrounded by the vertical member 5 and the horizontal member 6 becomes a parallelogram.

  As a result, the left and right frames 7 are shifted obliquely (in the plane direction of the vibration control panel model 3). Then, as shown in FIG. 4 (a), the two magnet sheets 8 that overlap each other slide and friction each other, so that the vibration energy of the building model 2 to which the vibration control panel model 3 is attached is absorbed as friction energy. Absorbs vibration energy of model 2. The amount of vibration energy absorbed can be changed by changing the strength of the magnet of the magnet sheet 8 or changing the contact area, so that the degree of vibration control effect can be experienced.

  On the other hand, in the building model 2 to which the seismic panel model 21 is attached, when the left and right frames 7 are displaced in the plane direction, the rubber sheet 22 repeats elastic deformation, but the rubber sheet 22 hardly absorbs vibration energy. Low damping and slow vibration On the other hand, the building model 2 to which the seismic control panel model 3 is attached absorbs vibration energy compared to the building model 2 to which the seismic panel model 21 is attached. Therefore, the vibration attenuation is large and the vibration is quickly settled.

  And by using the damping panel model 3 and the seismic panel model 21 to show the difference in amplitude and convergence speed of vibration, the damping performance of the building using the hysteresis damper (using the damping panel) ( The change in amplitude and time from when a force is applied and the vibration starts to decay and stop still) can be explained in an easy-to-understand manner without expertise.

  In addition, the damping performance is emphasized by modeling the damping panel and the earthquake-resistant panel using a magnet sheet, rubber sheet, etc. that can express their characteristics well compared to a model with a reduced size. Easy to understand. In addition, it is lightweight and can be easily carried, and production costs can be reduced. In addition, the vibration energy of the building model 2 can be absorbed by a visually well-understood operation of sliding friction between the two magnet sheets 8, and the vibration control performance of the building can be explained in an easy-to-understand manner.

  Further, the vibration damping performance can be easily changed by changing the sliding friction area and magnetic force of the magnet sheet 8. Moreover, the magnet sheet 8 is easily available, and it is easy to obtain a sheet having the same performance such as magnetic force. Even if the performance such as magnetic force is different, it is possible to easily obtain an energy absorber that exhibits uniform vibration performance by adjusting the sliding friction area. Therefore, a large number of vibration control panel models exhibiting uniform vibration performance can be produced at low cost.

  In addition, the vertical member 5 can be used as a spring plate to smoothly swing the building from side to side, and the proportion of the effect of the vibration control panel model 3 in which the energy absorber is provided in the building model 2 increases. The vibration of the building model 2 by the model 3 can be experienced.

  Moreover, by using the ground model 4, vibrations such as earthquakes can be applied to the building model 2, and the vibration control performance of the building using the energy absorber in an actual earthquake can be experienced. Moreover, by arranging the seismic control panel model 3 and the seismic panel model 21 side by side and fixing them to the ground model 4, the same vibration can be applied to the two building models 2, and the effect of the seismic control panel model 3 and the seismic panel model 21 Can be compared.

  In addition, by controlling the rocking width of the ground model 4 with the stopper 12, a constant initial amplitude can always be given, and further, the magnet sheet 8 is detached due to excessive deformation, or the vibration control panel model 3 is a building model. It can suppress that it removes from 2. FIG.

  The building model 2 to which the seismic control panel model 3 is attached and the building model 2 to which the seismic panel model 21 is attached can be removed from the ground model 4 and used. In this case, the building model 2 is vibrated by applying a force in the horizontal direction (left-right direction) to the upper part of the building model 2 with the bottom of the building model 2 fixed on the table or the like. You can also. Alternatively, the building model 2 may be vibrated by fixing the upper part of the building model 2 removed from the ground model 4 and applying a force in the horizontal direction (left-right direction) to the lower part.

[Sixth embodiment]
Next, another embodiment of the vibration suppression behavior explanation device according to the present invention will be described with reference to the drawings. FIG. 10 is a front view of a building model according to the present embodiment. About the part which overlaps with said 1st embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  As shown in FIG. 10, the vibration suppression behavior explanation device of this embodiment uses a building model 80 instead of the building model 2 of the first embodiment. Install the control panel model 3 etc. in the building model 80.

  The building model 80 includes left and right vertical members 81 and three cross members 6 joined between the vertical members, and can vibrate left and right. The lower part of the building model 80 is fixed on the ground model 4. The building model 80 is a model of a two-story building, and a rectangular space surrounded by the vertical members 81 and the horizontal members 6 represents the space of each floor such as the first floor and the second floor. The building model 80 is not limited to a two-story building, and may be a three-story or four-story model by providing a plurality of cross members.

A joint portion between the vertical member 81 and the cross member 6 is pin-joined, and a spring 82 is further provided at the joint. The spring 82 has one end fixed to the vertical member 81 and the other end fixed to the cross member 6. As a result, the building model 80 can swing smoothly from side to side. In order to make the building model 80 swingable and self-supporting, at least one of the joint portions of the longitudinal member 81 and the transverse member 6 is an elastic joint provided with a spring 82, and the other joint portion is a pin.

The vibration suppression behavior close to that of an earthquake can be explained in an easy-to-understand manner.

[Seventh embodiment]

FIG. 11 is a configuration diagram of a building model according to the present embodiment. FIG. 12: is the front view in the use condition of the building model concerning this embodiment, and a top view of the overlapping part. About the part which overlaps with said 1st embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

Further, as shown in FIG. 12B, the frame 92 has one side bent and is formed in an L shape. The frame 92 and the sheet 93 are formed of the same sheet of paper. A ladder-like vibration control panel model 91 is formed by overlapping the sheets 93 so that the two frames 92 are symmetrical. Then, the vibration control panel model 91 is attached in the building model 2 by pin-joining the upper and lower ends of the frame 92 to the upper and lower cross members 6.

  The overlapping order of the two overlapping portions is different from each other. For example, in FIG. 11, the overlapping order of the upper overlapping portions is such that the left sheet 93a is on the upper side and the right sheet 93b is on the lower side. Conversely, the overlapping order of the lower overlapping parts is such that the left sheet 93c is down and the right sheet 93d is up.

  By alternately stacking in this manner, the sheets 93 are bent, and the overlapping portions (sheets 93a and 93b, sheets 93c and 93d) are brought into close contact with each other due to the elasticity of the sheet 93 trying to return to the original straight state. In this state, sliding friction occurs in the surface direction at overlapping portions.

  The vertical members 5 and the cross members 6 of the building model 2 to which the vibration control panel model 91 is attached are made of paper. Since it is made of paper, the mass of the building model 2 is reduced, and vibration energy is smaller than that of a building model having a large mass in the case of the same amplitude. Therefore, the vibration of the building model 2 can be sufficiently damped only by energy absorption by the frictional force of the overlapping sheets 93. In addition, the building model 2 itself is even lighter and more portable and can be manufactured at a lower cost. It can also be distributed as a work set that can be easily worked at home, allowing the family to experience the vibration control performance while having fun.

  Further, the vertical member 5 and the horizontal member 6 may be configured by bending paper. As a result, the vertical members 5 and the horizontal members 6 are joined with a predetermined rigidity, and the building model 80 can swing smoothly from side to side and be able to stand on its own. Further, it can be easily manufactured as compared with the configuration using the pin joint and the spring 82, and the manufacturing cost can be reduced. Note that joints that cannot be manufactured by bending are joined by glue or tape.

  Note that the overlapping portions are not limited to two locations, and may be two or more locations. By increasing the number of overlapping portions, the sheet 93 can be more firmly adhered, and sliding friction can be reliably performed.

  In addition, since the frame 92 is formed in an L shape, the rigidity of the frame 92 is increased, and the frame 92 is not easily deformed even if the vibration control panel model 91 is repeatedly used, and the sheet 93 is more securely adhered. Thus, sliding friction can be ensured.

  Various members such as a leaf spring, a plastic plate, and a postcard can be used as the elastic sheet. Alternatively, only the energy absorber may be formed of a resilient sheet, and the other part (frame 92) may be formed of an iron plate or the like. By forming the energy absorber with an elastic sheet, it is lightweight and easy to carry, and manufacturing costs can be reduced. Further, the sliding frictional force can be easily adjusted.

  As shown in FIG. 12 (a), the left and right frames 92 are displaced in the plane direction by vibrating the building model 2 to which the damping panel model 91 using the seat 93 is attached in the same manner as in the first embodiment. The sheet 93 (93a and 93b, 93c and 93d) slides and rubs in the surface direction. By this sliding friction, the vibration energy of the building model 2 to which the vibration control panel model 91 is attached is absorbed as friction energy, and the vibration energy of the building model 2 is absorbed. Thereby, the effect similar to said 1st embodiment can be acquired.

  The amount of vibration energy absorbed can be changed by changing the material, surface roughness, and contact area of the sheet 93, so that the degree of vibration control effect can be experienced. Also, as shown in FIG. 12 (c), by bending the sheet 93 to give it a thickness, the bending of the sheet 93 can be increased to increase the frictional force and increase the amount of vibration energy absorbed.

  In addition, by making the entire vibration control panel model 91 made of paper, it is even lighter and more portable and can be manufactured at a lower cost. The vibration control panel model 91 can also be distributed as a work set that can be easily worked at home, so that the family can experience the vibration control performance while enjoying it.

[Eighth embodiment]
Next, another embodiment of the vibration suppression behavior explanation device according to the present invention will be described with reference to the drawings. FIG. 13 is a configuration diagram of a building model according to the present embodiment. About the part which overlaps with said 1st embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  As shown in FIG. 13, the vibration control panel model 101 of the present embodiment includes a notch 93a1 in the center of a sheet 93 formed on one frame 92 of the vibration control panel model 91 of the seventh embodiment. The sheet 93a2 is divided into 93a3.

  The stacking order of the upper sheet 93a2 and lower sheet 93a3 of the cut 93a1 and the sheet 93b of the other frame 92 is made different from each other. For example, in FIG. 13, the sheet 93a2 is on the top and the right sheet 93b is on the bottom. Conversely, the sheet 93a3 is on the bottom and the right sheet 93d is on the top.

  By overlapping in this manner, the sheets 93a2, 93a3, 93b are bent, and the overlapping portions (sheets 93a2, 93b, sheets 93a3, 93b) are brought into close contact with each other by the elasticity of the sheet 93 trying to return to the original straight state. In this state, sliding friction occurs in the surface direction at overlapping portions.

  The vibration control panel model 101 is also divided into two sheets 93c2 and 93c3 by making a cut 93c1 in the sheet 93c. Thus, by increasing the number of overlapping portions, the sheet 93 can be more closely contacted and can be slid reliably.

  However, the vibration control panel model of the present invention is not limited to such a configuration, and may include at least the sheets 93a2 and 93a3 and the sheet 93, and the above-described two positions may be overlapped. That is, it is not necessary to provide the convex portions 92b (sheets 93c and 92d) of the seventh embodiment.

  By vibrating the building model 2 to which the vibration control panel model 101 using the seats 93a2, 93a3, 93c2, and 93c3 is attached in the same manner as in the first embodiment, the left and right frames 92 are displaced in the plane direction, and the seat 93 ( 93a2 and 93b, 93a3 and 93b, 93c2 and 93d, 93c3 and 93d) slide and slide in the surface direction. By this sliding friction, the vibration energy of the building model 2 to which the vibration control panel model 101 is attached is absorbed as friction energy, and the vibration energy of the building model 2 is absorbed. Thereby, the effect similar to said 1st embodiment can be acquired.

  Further, as described above, the sheet 93a is cut and the overlapping portion is provided in the vicinity, so that the frame 92 can be prevented from being deformed, and the sheet 93 can be more closely contacted. Can be made to slide friction.

  As an application example of the present invention, it can be widely used for explanation of vibration control behavior of a building model with a vibration control panel model attached at a house exhibition hall or the like.
