DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] Before describing the vibration-damping structure of the present invention, a conventional vibration-damping structure will be briefly described. FIG. 1 is a diagram showing an example of a conventional vibration-damping structure using a viscoelastic body. The vibration-damping structure is, for example, a structure in which a vibration-damping device is attached between upper and lower beams (upper beam 11, lower beam 12) of a building and left and right columns 13. The vibration-damping device 10 includes a vibration-damping unit 14 and a transmission mechanism 15 that transmits shear deformation generated in the building to the vibration-damping unit 14. The vibration-damping unit 14 is composed of three plates and two viscoelastic bodies, and the viscoelastic bodies are disposed between the plates. The transmission mechanism 15 is composed of an upper transmission member 15a and a lower transmission member 15b attached to the upper beam 11 and the lower beam 12, and the vibration-damping unit 14 is attached between the upper transmission member 15a and the lower transmission member 15b.
[0010] Of the three plates of the vibration control unit 14, two plates on either side are attached to the upper transmission member 15a with their longitudinal direction horizontal, and the remaining plate between the two plates is attached to the lower transmission member 15b with its longitudinal direction vertical.
[0011] When shaking accompanied by shear deformation occurs in the building during an earthquake, the upper beam 11 and the lower beam 12 are displaced relatively in the horizontal direction, and the upper transmission member 15a and the lower transmission member 15b are also displaced relatively in the horizontal direction. The plates on both sides and the plate between them are also displaced relatively in the horizontal direction, and this is transmitted to each viscoelastic body. Each viscoelastic body absorbs the energy of the vibration accompanied by shear deformation.
[0012] Fig. 2 is a diagram showing the relationship between the deformation angle and the load of the viscoelastic body used in the vibration-damping structure shown in Fig. 1. The viscoelastic body used in the vibration-damping structure shown in Fig. 1 is, for example, high-damping rubber. As the high-damping rubber, for example, a rubber material such as natural rubber, styrene butadiene rubber, nitrile butadiene rubber, butadiene rubber, isopropylene, butyl rubber, halogenated butyl rubber, chloroprene rubber, or the like, which is produced by adding an additive that exhibits high damping properties, can be used. As the additive that exhibits high damping properties, for example, carbon black, silica, rosin, or other resins, or the like can be mentioned.
[0013] The high-damping rubber used here is high-damping rubber for detached houses, which are used for small buildings of around two stories. As shown in Figure 2, it can only withstand loads of up to 30 kN, which shows that it has a small bearing capacity.
[0014] For this reason, the shear deformation is also small and it is sufficient to transmit this small shear deformation. Therefore, as shown in Figure 1, the lower transmission member 15b has a simple structure having two braces extending diagonally from two points on both sides of the base material attached to the lower beam 12, and multiple bridges connecting the two braces.
[0015] For medium to large wooden buildings of three stories or more, the vibration control device 10 shown in Fig. 1 has a small bearing capacity and its performance is significantly insufficient. Specifically, it has only about 1 / 10 of the performance required for medium to large wooden buildings. The vibration control device 10 shown in Fig. 1 is a vibration control device for detached houses, which are generally installed on the first floor, with no consideration given to consecutive installation on each floor of higher floors, etc.
[0016] Fig. 3 is a diagram showing an example of a vibration control structure using a conventional steel damper. As shown in Fig. 3(a), this vibration control structure has a frame 20 having vertical members and horizontal members, a vibration control device 21 joined to the frame 20, and a joining structure 22 for joining the vibration control device 21 to the frame 20. The vibration control device 21 extends along the extension direction, and both ends in the extension direction are joined to the vertical members 20a and horizontal members 20b of the frame 20, respectively.
[0017] The vibration damping device 21 receives forces from both ends in the extension direction along the extension direction, absorbs vibration energy generated in the structural frame 20, and resists external forces received from the structural frame 20. As shown in Fig. 3(b), the vibration damping device 21 is composed of a core material 23 extending along the extension direction and a wooden restraining material 24 for restraining the buckling of the core material 23.
[0018] The vibration control structure shown in FIG. 3 has vibration control devices 21 joined at an angle to vertical members 20a and horizontal members 20b, and therefore can be installed in succession on each floor of a high-rise building.
[0019] However, because steel is used for the core material 23, it is necessary to embed the steel in the wooden restraining material 24 as a measure against buckling of the steel. The steel embedded in the restraining material 24 is not easy to visually inspect or replace. For this reason, maintenance and replacement work of the steel as a damper is difficult.
[0020] The present invention has been made to solve the problems of the conventional art, and provides a vibration-damping structure that can be used for medium- to large-scale wooden structures and that facilitates the maintenance and replacement of vibration-damping devices. Here, the present invention is described as a vibration-damping structure that can be used for medium- to large-scale wooden structures, but this vibration-damping structure is not limited to medium- to large-scale wooden structures.
[0021] 4 is a diagram showing an example of a vibration-damping structure according to this embodiment. The vibration-damping structure can be constructed on each floor of a building having multiple floors, and includes a wall material 30, a first flat plate 31, a second flat plate 32, and a vibration-damping device 33.
[0022] The wall material 30 is attached to a first structural member of the first story. The structural member is a pillar or a cross member (beam). The first flat plate 31 is provided so as to protrude from a second structural member facing the first structural member. The second flat plate 32 is provided so as to protrude from the wall material 30. The vibration damping device 33 includes a viscoelastic material member, and is fastened to each of the first flat plate 31 and the second flat plate 32 using fastening means.
[0023] Specifically, the first flat plate 31 is provided so that one end is embedded in a column or beam of one story of the building, and the other end is exposed and protrudes from the column or beam. In the example shown in FIG. 4, the first flat plate 31 is provided on an upper beam 40, which is a beam arranged on the upper side of one story. The upper beam 40 is made of wood, and has a groove (recess) into which one end of the first flat plate 31 can be inserted, which opens toward a lower beam 41, which is a beam arranged on the opposite lower side of the same story. After one end of the first flat plate 31 is inserted into the recess provided in the upper beam 40, a drift pin 34 is driven in and the first flat plate 31 is fixed to the upper beam 40. The first flat plate 31 fixed to the upper beam 40 has one end embedded in the upper beam 40, and the other end protrudes downward from the upper beam 40 and hangs down.
[0024] If the pillars or beams are made of reinforced concrete, holes through which the drift pins 34 pass can be made in advance at the locations where the drift pins 34 are to be driven, and the inner surface of the holes can be covered with a hollow cylindrical protective material such as rubber, and the drift pins 34 can be driven through the protective material. This is just one example, and is not intended to be limiting. This is to prevent the reinforced concrete from being damaged when the drift pins 34 are driven in.
[0025] The drift pins 34 are tapered steel rod-shaped members that are driven so as to penetrate from one side of the first flat plate 31 inserted into a recess provided in the upper beam 40 to the other side, which is the back surface of the first flat plate 31. A plurality of holes are provided on the edge of one end of the first flat plate 31, and the diameters of the holes match the diameter of the drift pins 34, so that the drift pins 34 can be driven into the holes to penetrate from one side of the first flat plate 31 to the other side. The same applies to the second flat plate 32, etc.
[0026] The pin method using drift pins 34 involves simply driving in the pins, which results in little cross-sectional loss and makes it easy to connect without the need for metal fittings or bolt tightening. The connection is also strong, improving earthquake resistance. This makes it easier to ensure the strength and fireproofing of joints required for medium- to large-scale wooden construction.
[0027] The wall material 30 is attached to the lower beam 41 facing the upper beam 40 by using the third flat plate 35. The lower beam 41 also has a recess that opens toward the facing upper beam 40 and into which one end of the third flat plate 35 is inserted, and one end of the third flat plate 35 is inserted into the recess. After one end of the third flat plate 35 is inserted into the recess, the drift pin 34 is driven in and the third flat plate 35 is fixed to the lower beam 41 in the same manner as described above.
[0028] The wall material 30 has recesses on both end faces facing the upper beam 40 and the lower beam 41. The other end of the third flat plate 35 is inserted into the recess provided on one end of the wall material 30 facing the lower beam 41, and the drift pin 34 is driven in as described above, and the wall material 30 is fixed to the lower beam 41 via the third flat plate 35. In the example shown in Fig. 4, the third flat plate 35 is configured of three plates, one in the center facing the surface of the wall material 30 and one on each side of the center.
[0029] One end of the second flat plate 32 is inserted into a recess provided in the other end of the wall material 30 facing the upper beam 40. The second flat plate 32 inserted into the recess provided in the wall material 30 is fixed to the wall material 30 by driving in the drift pin 34 in the same manner as described above.
[0030] 5, the vibration damping device 33 is fastened to the other end of the first flat plate 31 and the other end of the second flat plate 32 using a fastening means. The vibration damping device 33 includes, for example, three metal plate materials (plates) 50-52 and two viscoelastic members 53, 54 arranged between the plates 50-52. Here, the description will be given assuming that there are three plates 50-52 and two viscoelastic members 53, 54, but the numbers of the plates 50-52 and the viscoelastic members 53, 54 are not limited to these numbers.
[0031] The viscoelastic members 53 and 54 are members made of a material having both viscous and elastic properties, for example, high damping rubber. The viscoelastic members 53 and 54 have a strength about 10 times that of the high damping rubber for detached houses as a viscoelastic body shown in FIG. 1. Here, it is about 10 times that for detached houses, but it is not limited to this, and it may be 2 to 10 times, or it may be 10 times or more. The strength of the high damping rubber can be improved by increasing the amount of additives as reinforcing materials such as carbon black. Note that this is one example, and the strength may be improved by changing the type and composition of the additives added.
[0032] In the vibration damping device 33, two plates 50, 52 at both ends of the three plates 50-52 are arranged adjacent to each other so as to sandwich the other end of the first flat plate 31, and are fastened together using a bolt 55 and a nut as fastening means. In addition, in the vibration damping device 33, the remaining plate 51 in the middle of the three plates 50-52 is fastened to the second flat plate 32 using a mounting bracket 56 using a bolt 55 and a nut as fastening means. Here, the plate 51 and the second flat plate 32 are fastened together using the bolt 55 and a nut using the mounting bracket 56 having a step, but the plate 51 and the second flat plate 32 may be fastened together directly using the bolt 55 and a nut. Note that a gap is provided between the plates 50, 52 and the mounting bracket 56 so that they do not come into contact with each other even if the viscoelastic members 53, 54 are deformed.
[0033] The plates 50-52 and the sheet-like high damping rubber serving as the viscoelastic members 53, 54 are joined by an adhesive or the like. The viscoelastic members 53, 54 may be joined to the plates 50-52 by a method such as vulcanization adhesion. In addition to the reinforcing material such as carbon black described above, various additives such as a vulcanizing agent, a vulcanization accelerator, a vulcanization retarder, an anti-aging agent, a softener, and a plasticizer may be added to the high damping rubber as necessary.
[0034] The vibration control device 33 has the same configuration as the vibration control unit 14 shown in Fig. 1, and when shaking accompanied by shear deformation occurs in the structure during an earthquake, the upper beam 40 and the lower beam 41 are displaced relatively in the horizontal direction, and accordingly, the first flat plate 31 and the second flat plate 32 are also displaced relatively in the horizontal direction. Then, the two plates 50, 52 on both sides of the vibration control device 33 and the single plate 51 in the middle of the vibration control device 33 are displaced relatively in the horizontal direction, and this is transmitted to the two viscoelastic members 53, 54. The two viscoelastic members 53, 54 deform themselves and absorb the energy of the vibration.
[0035] In the example shown in FIG. 4, four vibration damping devices 33 are installed adjacent to each other along the longitudinal direction of the beam.
[0036] The first flat plate 31, the second flat plate 32, and the third flat plate 35 are less likely to deform laterally in the longitudinal direction of the beams than their respective face sides, and one end of each is inserted and fixed to fit into recesses provided in the upper beam 40, the lower beam 41, and the wall material 30, so that they transmit vibration energy appropriately to the connected counterparts, the vibration control device 33 and the wall material 30, in response to shaking in the longitudinal direction. The wall material 30 is also wider than the first flat plate 31, etc., so that it is less likely to deform laterally in the longitudinal direction of the beams, and the other end of the third flat plate 35 is inserted and fixed into the recess and onto the lower beam 41, so that they transmit vibration energy appropriately to the connected counterpart, the second flat plate 32, in response to shaking of the lower beam 41.
[0037] The first flat plate 31, the second flat plate 32, and the third flat plate 35 have a certain thickness and are embedded in the beams, and the wall material 30 also has a certain thickness, so that they have a certain strength in the respective planar directions perpendicular to the longitudinal direction of the beams and are not easily deformed, and therefore can transmit vibration energy appropriately even in the planar directions. The first flat plate 31 and the third flat plate 35 are fixed to the upper beam 40 and the lower beam 41 by multiple drift pins 34, the second flat plate 32 is also fixed to the wall material 30 by multiple drift pins 34, and the wall material 30 is also fixed to the third flat plate 35 by multiple drift pins 34, so that vibration energy can be transmitted appropriately even in the vertical direction, which is the longitudinal direction of the pillars.
[0038] To be adopted as a vibration control structure for medium to large-scale wooden buildings, the vibration control device 33 needs to have the high damping rubber capacity, as well as the ability to properly transmit vibration energy to the high damping rubber. The conventional structure shown in Figure 1 is easily deformed and is therefore unable to properly transmit vibration energy.
[0039] On the other hand, in the vibration control structure of this embodiment, as described above, the first flat plate 31 etc. are less likely to deform and are firmly fixed to the upper beam 40 etc., so that vibration energy can be appropriately transmitted to the vibration control device 33.
[0040] Furthermore, since medium- to large-scale wooden buildings are high-rise, they tend to shake more and transmit more vibration energy. The vibration-damping structure according to this embodiment uses wall materials 30 and the like that can transmit the large vibration energy appropriately, and furthermore, high-damping rubber with a strength approximately 10 times that of detached houses is used, so that even on the high floors of medium- to large-scale wooden buildings, the transmitted vibration energy can be absorbed appropriately.
[0041] Furthermore, recesses are formed in the upper beams 40 and the lower beams 41, each flat plate is inserted and fixed in place by driving in drift pins 34, the wall material 30 is installed and fixed in place with drift pins 34, and the vibration control device 33 is fastened with bolts and nuts for easy installation, making it possible to arrange the structures in layers on each floor.
[0042] When fastening the first flat plate 31 and the second flat plate 32 to the vibration damping device 33 for medium to large wooden structures, if the joints are deformed, it will not be possible to transmit vibration to the high damping rubber. For this reason, it is preferable to use high tension bolts with high strength and tensile force as fastening means, rather than normal bolts. High tension bolts have a tensile strength of 490N / mm 2 The bolts are manufactured using the above steel materials.
[0043] Holes through which high-tension bolts can pass are formed at predetermined positions in the other end of the first flat plate 31, the other end of the second flat plate 32, and the three plates 50-52 of the vibration damping device 33, and the vibration damping device 33 can be fastened to the first flat plate 31 and the second flat plate 32 using the high-tension bolts and nuts.
[0044] The vibration control device 33 is installed in an exposed state from the pillars and beams so that inspection and replacement can be easily performed.
[0045] The wall material 30 may be made of commonly used laminated timber or plywood, but CLT (Cross Laminated Timber) is preferable because it can transmit the ability of the high-damping rubber with high vibration-damping performance used in the vibration-damping device 33 to the building. Laminated timber is a building material made by stacking multiple laminas, which are cut into boards from natural wood, with the wood fibers running in the same direction and gluing them together with adhesive. Plywood is a building material made by stacking thin single boards with the wood fibers running in the same direction, alternating between vertical and horizontal directions and gluing them together with adhesive. CLT is a building material made by arranging laminas in parallel to make several boards so that the wood fibers run in the same direction, and then stacking and gluing these boards together in a staggered manner so that the wood fibers run at right angles to each other.
[0046] CLT is lighter than reinforced concrete or steel, and has higher strength than these materials. CLT is also less prone to deformation and damage during earthquakes, making it highly earthquake-resistant. CLT is also fire-resistant and has good thermal insulation properties.
[0047] In the example shown in Fig. 4, vibration control structures are constructed on the first and second floors of a wooden building as an architecture, but it is also possible to construct them on higher floors, such as the third floor and above. Also, the upper beam 40 and the lower beam 41 are connected to each other using the first to third flat plates 31, 32, 35, the wall material 30, and the vibration control device 33 to construct a vibration control structure, but the left and right columns 42 may also be connected to each other using these to construct a vibration control structure.
[0048] Fig. 6 is a diagram showing the relationship between displacement (mm) and load (kN) when the vibration control structure according to this embodiment shown in Fig. 4 is adopted. Static testing is a testing method in which a force is applied to a building, the force is stopped at each certain deformation, and the displacement is measured, and is a method that is not affected by time or the force application speed. Material testing is a dynamic testing method in which a force that is assumed to be actually applied to a building is applied to the building, and the displacement is measured.
[0049] In the vibration control structure according to this embodiment, a high-damping rubber damper with a strength about 10 times that of a high-damping rubber damper for detached houses is used, and CLT is used as the wall material 30 that can transmit this capacity to the building, so it is possible to obtain the effect of damping vibrations even when a load of more than 300 kN is applied. This means that the damping capacity is more than 10 times that of a high-damping rubber damper for detached houses, which can only damp vibrations up to 30 kN.
[0050] In a high-rise building, it is necessary to place a vibration control device on each floor, but it is not enough to simply increase the resistance of a high-damping rubber damper by ten times; it is necessary to connect the vibration control device 33 with a transmission member that can properly transmit the capacity to the building. Members that easily deform or structures that easily tilt cannot properly transmit the capacity of the vibration control device 33 to the building. In other words, the vibration energy from beams, etc. cannot be properly transmitted to the vibration control device 33 and absorbed.
[0051] The vibration control structure of this embodiment uses the above-mentioned wall material and multiple flat plates, and therefore can properly transmit vibration energy to the vibration control device 33 without deformation, etc., and the vibration control device 33 also uses high-damping rubber or the like with high vibration control performance, and therefore can properly absorb vibration energy.
[0052] In addition, since the vibration-damping device 33 is exposed and fastened to the other end of the exposed first flat plate 31 and the other end of the second flat plate 32 by bolts and nuts as fastening means, visual inspection can be easily performed, facilitating maintenance and management. Moreover, the vibration-damping device 33 can be easily removed by removing the bolts and nuts, making replacement work easy.
[0053] In the example shown in Fig. 4, one story has one first flat plate 31, one second flat plate 32, three third flat plates 35, and four vibration control devices 33, but the numbers are not limited to these and may be any number. When installing the wall material 30 on a concrete foundation, the third flat plate 35 can be installed by bending the cross section into an L-shape, for example, and embedding one end of it into the concrete foundation together with a fixing means such as an anchor bolt.
[0054] The vibration control structure of the present invention has been described in detail above with reference to the embodiments shown in the drawings. However, the present invention is not limited to the above-described embodiments, and can be modified within the scope of what a person skilled in the art can conceive, including other embodiments, additions, modifications, deletions, etc., and any aspect is within the scope of the present invention as long as it achieves the functions and effects of the present invention.
