  The present invention has been made in view of the above-described drawbacks of the conventional vibration damping device. The configuration is extremely simple and inexpensive, and can be easily attached to an existing structure. An object of the present invention is to provide a vibration damping reinforcement device that can be used.

The present invention is a vibration damping reinforcement device attached to an opening surrounded by left and right column members and upper and lower horizontal members of a structure, wherein at least upper and lower frame sides are fixed to the upper and lower horizontal members, respectively. A rectangular frame that can be deformed into a parallelogram shape, and a plurality of wooden members arranged in parallel inside the frame, and when the frame body is deformed into a parallelogram shape, The wooden member is made of a metal material, the wooden member is a long square bar wood along the wood structure, and the square bar wood is arranged vertically. It is characterized by being arranged side by side in parallel .

In addition, the present invention is characterized by comprising holding means for holding the plurality of juxtaposed wood members in pressure contact with each other.

  Furthermore, in the present invention, the holding means includes a through hole formed in each wooden member, a bolt inserted into the through hole of each wooden member, and a nut screwed into the bolt. It is characterized by being.

  The vibration-damping / reinforcing apparatus according to the present invention can be easily configured by simply fixing a buffer body in which a plurality of wooden members are arranged in parallel so as to be relatively displaceable to each other inside the frame. Therefore, it is possible to provide a vibration-damping / reinforcing device that is simple in structure and inexpensive, without causing a complicated apparatus configuration and an increase in manufacturing cost unlike a conventional product using a hydraulic damper.

  In addition, since the vibration damping reinforcement device according to the present invention can be easily attached to the opening by simply fitting it into the opening of the structure to be reinforced and fixing the frame to the horizontal member and the column member, Unlike conventional products, there is no need for installation work.

  Moreover, according to the vibration damping reinforcement apparatus which concerns on this invention, the load of a structure can be supported by the several wooden member in the state attached to the opening part, and an opening part can be reinforced. And since these several wooden members are hold | maintained and bundled with the frame, they are excellent in load-bearing property.

  And at the time of an earthquake etc., a frame deform | transforms into a parallelogram shape with a pillar material and a horizontal member, and the several wooden member paralleled within the frame displaces relatively mutually. Therefore, vibration energy at the time of an earthquake or the like can be absorbed by the frictional resistance between the wooden members at the time of relative displacement, and an excellent vibration damping effect is exhibited. Further, if necessary, if a holding means for holding the wooden members in a pressure contact state is provided, the frictional resistance between the wooden members can be increased, and vibration energy can be absorbed more effectively.

  Furthermore, according to the vibration damping reinforcement device according to the present invention, when the frame body is deformed into a parallelogram shape, the distance between the left and right frame sides of the frame body is smaller than normal. A plurality of wood members are also pressed into contact with each other by deformation in the shear direction. Therefore, the greater the shaking during an earthquake or the like, the greater the frictional resistance between the wooden members and the more effective the vibration damping effect.

  Hereinafter, the vibration damping reinforcement device 10 of the present embodiment will be described in detail with reference to FIGS.

  As shown in FIGS. 1 and 2, the vibration damping reinforcement device 10 of the present embodiment is configured as a rectangular wall-like body having a certain thickness and viewed from the front. And it attaches to the opening part 14 enclosed by the left and right pillar materials 11 * 11 of the existing wooden structure 1, the duck 12 which is an upper horizontal material, and the sill 13 which is a lower horizontal material. FIG. 1 illustrates an example in which vibration damping reinforcement devices 10 are partially disposed on both the left and right sides of the opening 14 one by one.

  As shown in FIG. 2 and FIG. 3, the vibration damping reinforcement device 10 of the present embodiment mainly includes a deformable rectangular frame 2 to be fixed to a pillar and a horizontal member of the structure, and the frame 2. The shock absorber 5 is disposed inside the shock absorber 5 and absorbs vibration energy during an earthquake or the like, and the holding means 6 that holds the plurality of wood members 51 constituting the shock absorber 5 in a pressure contact state with each other.

  As shown in FIG. 3, the frame 2 is configured as a vertically long rectangular frame member by bending and welding a belt-shaped steel plate 25, and includes upper and lower frame sides 21 and 22 and left and right frame sides 23. 24. And the collar part 31 is formed in the both-sides edge of each frame edge, and the several attachment hole 32 is opened in each collar part 31 at predetermined intervals. By passing screws (not shown) from the inside of the frame body 2 through the mounting holes 32 and screwing the screws into the column member and the horizontal member, the frame member 2 can be fixed to the column member and the horizontal member. Of course, the frame 2 may be fixed using nails instead of screws. In this embodiment, as shown in FIG. 1, the three sides of the vibration damping reinforcement device 10 are fixed to the upper and lower horizontal members (the duck 12 and the sill 13) and the column material 11 on one side of the opening 14. . Therefore, in the present embodiment, the upper and lower frame sides 21 and 22 and one frame side 24 of the frame 2 are provided with the flanges 31, and the other frame side 23 is not provided with the flanges.

  In addition, a plurality of fastening holes 41 are opened at predetermined intervals in the center in the width direction of all the frame sides 21, 22, 23, and 24 of the frame 2. The fastening holes 41 are provided for fixing the buffer body 5 fitted inside the frame body 2, and screws 42 (see FIG. 2) are provided in the fastening holes 41 from the outside of the frame body 2. The buffer body 5 is disposed in the frame body 2 by screwing the screws 42 into the buffer body 5 in the frame body 2. The buffer body 5 may be fixed using a nail instead of the screw 42. In the present embodiment, no reinforcing portion such as a reinforcing lip extending between two adjacent frame sides is provided at each corner of the frame 2. Therefore, during an earthquake or the like, the corners of the frame body 2 can be deformed relatively easily, and the entire frame body 2 can be deformed into a parallelogram shape.

  As shown in FIGS. 3 and 4, the buffer body 5 is configured by arranging a plurality of wood members 51 in parallel. In the present embodiment, as the wooden member 51, a long square bar wood obtained from thinned wood is used. The buffer body 5 is configured by vertically arranging a total of six square bar timbers having the same length as the inner method in the height direction of the frame body 2 in parallel.

  As shown in FIGS. 3 and 4, the holding means 6 includes a through hole 61 formed in each wooden member 51, a bolt 62 inserted into the through hole 61 in a loosely fitted state, and a front end side of the bolt 62. It is comprised from the nut 63 provided with the internal thread which can be screwed together in the engraved external thread. The bolts 62 are continuously inserted into the through holes 61 of the six wood members 51 arranged in parallel, and the nuts 63 are screwed into the bolts 62 and tightened, so that the wood members 51 are held in a pressure-contact state so that they can be displaced relative to each other. The In the present embodiment, counterbore portions 64 are formed in the through holes 61 of the wooden members 51 at both ends, and the heads of the bolts 62 and the nuts 63 are accommodated in the counterbore portions 64. Therefore, the holding means 6 does not protrude outward on the side surface of the buffer body 5, and the buffer body 5 can be fitted into the frame body 2 with almost no gap. Moreover, in this embodiment, as shown in FIG. 3, the holding means 6 is provided in three places, the upper part, the center part, and the lower part of the buffer body 5 in the longitudinal direction.

  As described above, in the present embodiment, the plurality of wood members 51 are pressed and held by the holding means 6 to form the buffer body 5, and the buffer body 5 is fixed to the inside of the frame body 2 with the screw 42 to suppress vibration. A reinforcing device 10 is configured (see FIG. 2). Therefore, it is possible to provide a vibration-damping / reinforcing device that is simple in structure and inexpensive, without causing a complicated apparatus configuration and an increase in manufacturing cost unlike a conventional product using a hydraulic damper.

  Further, the vibration damping reinforcement device 10 of the present embodiment is simply fitted into the opening of the structure to be reinforced, and only the flange portion 31 of the frame 2 is fixed to the horizontal member and the column member of the structure. It can be easily installed (see FIG. 1), and it does not take time for installation work. In addition, after attaching to an opening part, of course, decorative members, such as a wallpaper, can be stuck on the surface of a vibration suppression reinforcement apparatus, and the appearance can be improved. It is also possible to paste a decorative member on the surface of the vibration damping reinforcement device in advance before attachment.

  Further, the vibration damping reinforcement device 10 attached to the opening reinforces the opening by supporting the load of the structure with the plurality of wooden members 51 of the buffer body 5. In the present embodiment, the square bar woods excellent in compressive strength in the tissue direction are arranged vertically in parallel, and the plurality of square bar woods are further joined by the frame 2 made of a steel material excellent in tensile strength, and further by bolts and Since it is bundled by the holding means 6 made of a nut, it is excellent in load resistance. Therefore, the cross-sectional area (front width × thickness) of the vibration damping reinforcement device 10 can be made small. For example, the thickness of the vibration damping reinforcement device 10 is less than half the width of the sill 13 as shown in FIG. It is also possible to design. Thus, even after the vibration damping reinforcement device 10 is attached, the bag or the shoji can be used at the opening.

  Further, in the vibration damping reinforcement device 10 of the present embodiment, in the event of an earthquake, as shown in FIG. 5, the frame body 2 is deformed in a shearing direction into a parallelogram together with the pillar material and the horizontal member, and this frame body. The plurality of wood members 51 arranged in parallel in 2 are displaced relative to each other. Therefore, vibration energy at the time of an earthquake or the like can be absorbed by the frictional resistance between the wooden members 51 at the time of relative displacement, and an excellent damping effect is exhibited. In the present embodiment, since the plurality of wooden members 51 are held in pressure contact with each other by the holding means 6, the frictional resistance between the wooden members 51 can be increased, and vibration energy can be absorbed more effectively. .

  Moreover, as shown in FIG. 5, when the frame body 2 is deformed into a parallelogram shape, the interval S between the left and right frame sides 23 and the frame side 24 of the frame body 2 is smaller than the interval T in normal times. Therefore, the plurality of wooden members 51 are pressed against each other even when the frame body 2 is deformed in the shearing direction. Therefore, the greater the vibration during an earthquake or the like, the greater the frictional resistance between the wooden members 51 and the more effective the damping effect.

  Further, in the vibration damping reinforcement device 10 of the present embodiment, since the plurality of wooden members 51 are held by the holding means 6, the wooden members 51 at both ends are respectively fixed to the frame sides 23 and 24 of the frame body 2. As long as it vibrates, there is no possibility that the intermediate wooden member 51 will fall off the frame 2. With this, it is possible to provide a vibration damping reinforcement device that has a simple structure but reliably exhibits a vibration damping effect.

  As mentioned above, although typical embodiment was described about the vibration suppression reinforcement apparatus which concerns on this invention, the vibration suppression reinforcement apparatus which concerns on this invention can also be implemented with another form.

  For example, in the above-described embodiment, the buffer member 5 is configured by arranging the wooden members 51 made of square bar wood by simply bringing the side surfaces into contact with each other. For example, as shown in FIG. A convex portion 53 is formed on the side surface of the wooden member 52 along the longitudinal direction, and a concave portion 54 is formed on the side surface of the other wooden member 52 along the longitudinal direction. The convex portion 53 and the concave portion 54 are The buffer body 5 may be configured by fitting. As a result, the contact area between the wooden members 52 can be increased, and the intermediate wooden member 52 can be prevented from falling off during an earthquake without the holding means 6 being provided.

  Moreover, in the said embodiment, although the square bar timber which has the length substantially the same as the internal method of the height direction of the frame 2 is employ | adopted as the wooden member 51 which comprises the buffer body 5, of course, this invention is this. For example, a plurality of wooden members that have substantially the same length as the inner method in the height direction of the frame body 2 by being arranged vertically as in the vibration damping reinforcement device 20 shown in FIG. You may comprise the buffer 5 using 55 * 56. Here, an example in which two types of wood members 55 and 56 having different lengths are used is shown. This makes it easier to obtain the wooden member, and can reduce the manufacturing cost of the vibration damping reinforcement device.

  Moreover, you may comprise the inner side space of the frame 2 by several small space like the vibration suppression reinforcement apparatus 30 shown in FIG. Here, the inner space of the frame body 2 is bisected by connecting the intermediate portions of the left and right frame sides 23 and 24 of the frame body 2 with the intermediate frame side 26. In these two inner spaces, the buffer bodies 5 each having a plurality of wood members 57 arranged in parallel are arranged. During an earthquake or the like, both of these two inner spaces are deformed into a parallelogram shape, so that vibration energy can be absorbed by the frictional resistance between the wooden members as in the above embodiment.

  Moreover, in the said embodiment, although the holding means 6 which press-holds the several wooden member 51 is comprised from the volt | bolt and the nut, this invention is not limited to this at all, For example, the parallel several A plurality of wooden members may be held in pressure contact with each other by fitting a steel annular member (saddle member) around the outer periphery of the wooden member or by winding a rubber band member.

  Moreover, since the vibration suppression reinforcement apparatus which concerns on this invention has arrange | positioned the several wooden member which comprises a buffer body in a frame, it is not necessarily required to provide a holding means. If a plurality of wooden members are fitted into the frame body in a compressed state using its elasticity, the plurality of wooden members can be held in pressure contact with each other by this frame body. Further, an elastic material may be interposed between the frame body and the buffer body in a compressed state, and a plurality of wooden members may be held in pressure contact by the elastic material.

Moreover, in the said embodiment, although the timber obtained from the thinned material is used as the wooden member 51, you may use the laminated material which adhere | attaches several timber. Further, the number of wooden members and the cross-sectional shape are not limited to the above embodiment, and various design changes are possible. Moreover, in the said embodiment, although the frame 2 is formed with steel materials , you may form with other metal materials , such as an aluminum material, for example . Since the vibration-damping / reinforcing apparatus according to the present invention can mainly support the load of the structure with a wooden member, the frame 2 itself does not necessarily need the strength to support the load of the structure. Therefore, the frame body 2 can be deformed into a parallelogram shape together with the horizontal member and the column member at the time of an earthquake, and only has a strength capable of maintaining the parallel state of these wooden members at the time of relative displacement of the wooden members. Various materials can be adopted.

  Moreover, in the said embodiment, as shown in FIG. 1, the three sides of the vibration damping reinforcement apparatus 10 are fixed to the up-and-down horizontal member of a structure, and the pillar material of one side, and the vibration damping reinforcement apparatus 10 of the opening part 14 is fixed. Although an example in which it is partially attached to the side part has been described, the present invention is of course not limited to this, for example, all four sides of the vibration damping reinforcement device It is also possible to attach the vibration damping reinforcement device so as to be fixed to the column member and close the opening. In this case, it is preferable to provide flanges on all the frame sides on the top, bottom, left and right of the frame body 2. Further, the upper and lower sides of the vibration damping reinforcement device may be fixed only to the upper and lower horizontal members of the structure, and the vibration damping reinforcement device may be partially attached to the middle of the opening. Furthermore, a plurality of vibration damping reinforcement devices may be attached in parallel to one opening. Further, when attaching the vibration damping reinforcement device to the opening, a spacer or a wedge material may be interposed between the column member or the horizontal member and the frame.

  The present invention can be carried out in a mode in which various improvements, modifications, and variations are added based on the knowledge of those skilled in the art without departing from the spirit of the present invention. In addition, any invention-specific matters may be replaced with other technologies within a range where the same action or effect occurs, and the integrally-configured invention-specific matters are constituted by a plurality of members. Alternatively, the invention specific items configured by a plurality of members may be implemented in an integrated configuration.
