  In order to reduce the shaking of the wooden house due to the earthquake, install a damping device that suppresses the angular displacement of the entrance corner surrounded by the beam and column, or install a damping device that reduces the relative displacement of the beam and the base. It is a problem to be solved by the present invention to reduce the degree of destruction.

  Clockwise direction (CW) → Counterclockwise direction (CCW) → Clockwise direction (CW) or Counterclockwise direction (CCW) → Clockwise direction (CW ) → Metal or carbon resin leaf spring bent into an odd number of continuous arcs as in the counterclockwise direction (CCW), and for the fixing pin at the same position as the center of the arc. A cylindrical rubber for attenuating the deformation of the leaf spring (hereinafter also simply referred to as a cylindrical rubber) and two cylindrical guide rollers that are tightly inserted inside the cylindrical rubber between two holding plates with through holes. By installing a set of vibration control devices in the corners of the beam and column, the set is fixed with a fixing pin so that the leaf spring itself is sandwiched between the three cylindrical rubbers at the three through-hole positions. Can be suppressed.

  Further, if a set of vibration control devices is installed and fixed around the center of the beam, and the base and the vibration control device are connected and fixed, the relative displacement between the beam and the column can be suppressed.

  When a set of vibration control devices is installed in the corner, the metal leaf springs that have been subjected to three consecutive arc-bending processes are also obtusely deformed due to the shaking of the corner due to the shaking of the earthquake. In addition to acting in a direction to suppress obtuse angle deformation at the corner of the corner by force, a damping cylindrical rubber fixed with the restraining plate at the center of the three arcs suppresses the deformation of the leaf spring and also attenuates the amplitude of the leaf spring. As a result, it is possible to reduce the shaking of the house.

  If a set of vibration control devices is installed at the center of the beam, the beam can be controlled by suppressing the free vibration of the beam against earthquake shaking if the set of vibration control devices are connected and fixed to the base (floor) with a connecting device. And the relative displacement of the base (floor) can be suppressed, and the effect of reducing the shaking of the house is achieved.

  In addition to changing the value of each arc with the same radius, the set of damping devices can be changed by combining different diameters of arcs or changing the outer diameter of the damping rubber suitable for each arc. The spring constant and damping coefficient can be changed, and a vibration control device suitable for the design of the house becomes possible.

  Furthermore, if the bracing is screwed between the restraining plates to which the bracing is added to the restraining plates instead of the restraining plates used for the one set of vibration control devices in the above paragraph 0014, the one set of damping devices is provided. By adding a seismic device between the entrance corner and the bracing, the seismic control method can attenuate the deformation vibration of the entrance corner due to the shaking of the earthquake and reduce buckling fracture of the bracing.

  Also, without bending the straight portions at both ends of the leaf spring having three continuous arcs shown in the above paragraph 0014, the straight portions at both ends extending in the tangential direction of the arc at the connecting portion between the arc and the straight portion are on one straight line. The straight spring is drilled with bolt holes or screw holes for fixing to the beam or foundation (floor), and the outer diameter is the same diameter as the three arcs. A damping cylindrical rubber with a guide roller and a guide roller that is closely inserted inside the cylindrical rubber are arranged at the same position as the three arc centers, together with a leaf spring, and a through hole for a fixing pin is located at the same position as the arc center. At the same time as sandwiching both ends of the guide roller with the holding plate, a set of vibration control devices with a shape that can fix the base (floor) and connecting device is installed and fixed to the lower part of the beam. With the foundation (floor) below By binding fixed, the vibration control method capable of suppressing the relative displacement of the beam and the base by the earthquake shaking (floor).

FIG. 1 shows a front view of a set of damping device 1001 of the present invention. As shown in FIG. 4, one end (aa) portion of a metal leaf spring 1 having a thickness t is shown in FIG. The leaf spring 1 has a linear shape, is bent so as to form three continuous arcs having inner diameters R ₁₁ , R ₁₂ , and R ₁₃ , and the other end (bb) is processed into a linear shape. The cylindrical rubber 3 and the guide roller 9 are arranged at the same position as the three arc centers, and as shown in FIGS. 2 and 3, the insertion hole 8 (for the following embodiments) for the fixing pin 13 is located at the same position as the arc center. The plate spring 1, the cylindrical rubber 3, and the metal guide roller 9 are fixed to the fixing pin 13 and the E type so as to be sandwiched between the holding plates 5 and 7 having the fixing plate insertion hole 8 for the holding plate. An outline of a set of vibration control devices 1001 configured to be fixed by a retaining ring 11 is shown.

  Further, as shown in FIG. 1, each extension plane of the installation plane including the straight portion (aa) and the installation plane including the straight portion (bb) when the leaf spring 1 is installed on the beam or column is 90. The leaf spring 1 is formed so that it intersects at an angle and becomes the coordinate origin O of the XY coordinate on the intersecting line, so that the straight portions (aa) and (bb) are bolts 15 at the corners. And the nut 17 can be installed and fixed.

The leaf spring 1 having a thickness of t and an arc bending in a clockwise direction (C.W) in inner diameter _{R 11,} subsequently, an arc bending in a counterclockwise direction (C.C.W) at the inner diameter R ₁₂ Furthermore, the portion of the inner radius R ₁₃ that has been subjected to continuous arc bending in the clockwise direction (C.W) is (cc), and both ends thereof are straight portions (aa) and (bb). It has become. Here, when R ₁₁ = R ₁₂ = R ₁₃ , the line connecting the three arc center points forms a right isosceles triangle. The cylindrical rubber 3 shown in FIG. 5 has an outer diameter equal to the inner diameter of each arc. In this figure, R ₁₁ = R ₁₂ = R ₁₃ is used, and therefore the same cylindrical rubber 3 is used. Further, the guide roller 9 having the same outer diameter as the inner diameter of the cylindrical rubber 3 is tightly inserted into the inner side of the cylindrical rubber 3 to prevent the positional deviation.

  FIG. 6 is a perspective view of a set of vibration control devices 1001, and FIG. 7 is an exploded view. As in the paragraph 0018, as shown in FIG. 6, the installation surface of the leaf spring 1 including the straight portion (aa) is the X coordinate plane, and the installation surface of the leaf spring 1 including the straight portion (bb) is Y. When the origin of the intersection of the XY coordinate plane and the plane including the isosceles triangle at the center of the three arcs of the restraint plate 7 is the origin O, the intersection of the X coordinate plane and the Y coordinate plane The direction from the restraining plate 7 to the restraining plate 5 along a parallel line with the fixing pin 13 is regarded as the positive (+) direction of the Z coordinate. FIG. 7 shows the guide rollers 9 arranged at the three arc center positions of the leaf spring 1 between the holding plates 5 and 7 having the through holes of the fixing pin 13 at the same position as the center point of each arc of the leaf spring 1. And the cylindrical rubber 3 is sandwiched between restraining plates 5 and 7 so as not to be detached from the leaf spring 1, and a disassembled and assembled structure of a set of vibration control devices 1001 positioned and fixed by a fixing pin 13 and an E-type retaining ring 11 is shown. Yes.

  Here, FIG. 8 is a front view when only the leaf spring 1 is fixed with bolts 15 and nuts 17 at four corners surrounded by the beam 19, the column 21 and the base (floor) 23, respectively. Is FIG. Further, FIG. 10 is a front view assuming that the column 21 is inclined due to the earthquake and the beam 19 and the base (floor) 23 are relatively displaced, and FIG. 11 is a perspective view thereof. Here, among the four corners shown in FIGS. 10 and 11, the corners on the upper left and the lower right corners are acute angles (<90 °), and the corners on the upper right and lower corners are obtuse angles (> 90 °), the arc shape is deformed into an ellipse, and the restoring force of each leaf spring 1 serves to suppress the shaking of the earthquake in accordance with the deformation.

Next, FIG. 12 is a front view in which a set of vibration control devices 1001 is installed and fixed with bolts 15 and nuts 17 at four corners surrounded by beams 19, columns 21 and a base (floor) 23. FIG. FIG. 13 is a cross-sectional side view seen from the AA direction. FIG. 14 is a perspective view of FIG. In this way, by installing and fixing one set of vibration control devices 1001 in the corners, the column 21 is inclined with respect to the beam 19 and the base (floor) 23 by the shaking of the earthquake, so that each corner is an acute angle. Or the obtuse angle deformation | transformation WHEREIN: The circular arc shape of the leaf | plate spring 1 deform | transforms into an elliptical shape, and the leaf | plate spring 1 suppresses and dampens the vibration deformation of the leaf | plate spring 1 by pinching | interposing the cylindrical rubber 3 located in the circular arc center. As a result, the relative displacement between the beam 19 and the base (floor) 23 is reduced.
Here, the fixing pins 13 and the E-type retaining ring 11 are used to position and fix the holding plates 5 and 7. However, in place of the fixing pins 13 and the E-type retaining ring 11, a combination of bolts and nuts is combined. Similarly, in the following embodiments, the fixing pin and the E-type retaining ring are not particularly concerned. The material of the leaf spring may be not only made of metal but also resin such as carbon resin. The cylindrical rubber 3 and the metal guide roller 9 are fixed by an adhesive or vulcanization, or integrated. Molded parts may be used. Furthermore, the guide roller 9 may be made of not only metal but also hard resin.

  Instead of the restraining plates 5 and 7 used in a set of vibration control devices 1001, the plate spring 1 has through holes for positioning and fixing pins 13 at the same position as the center of the arc, and penetrates for fixing the braces. FIG. 15 is a front view of a set of vibration control devices 1003 using the holding plates 25 and 27 provided with holes 73, FIG. 17 is a side view thereof, and FIG. Similarly to the paragraphs 0018 and 0020 of the first embodiment, as shown in FIGS. 15 and 17, the surface of the leaf spring 1 including the straight portion (aa) is defined as an X coordinate plane, and the straight portion (bb) is obtained. ) Is a Y coordinate plane, the XY coordinate plane intersects at 90 °, and a plane including an isosceles triangle connecting the intersecting line and the three arc centers of the restraining plate 27. When the intersection point is the coordinate origin O, as shown in FIG. 17, the intersection point forms an angle of 90 ° with each of the X coordinate direction and the Y coordinate direction, and is suppressed by a parallel line with the fixing pin 13. Assuming that the direction from the base plate to the holding plate 25 is the positive (+) direction of the Z coordinate, the same coordinate system concept is applied to a set of vibration control devices for the corners thereafter.

  A set of vibration control devices 1003 is installed and fixed at each of the two corners surrounded by the beam 19 and the column 21, the bracing 29 is attached, and the bracing connection fixing member 31 and the bracing-base fixing member 33 are used. The perspective view which showed the mode at the time of connecting the said 2 damping device 1003 with the base (floor) 23, and also installing and fixing one set of damping devices 1001 in the other corner of the drawing, respectively. FIG. Since the vibration is transmitted to the braces via one set of vibration control devices 1003, the probability that the buckling of the braces will occur is reduced as compared with the case where the braces are installed directly in the corner. Furthermore, if one set of seismic control devices 1001 is used in combination, it is possible to improve each seismic performance. Further, the material of the leaf spring shown in the embodiment is not limited to metal, and may be made of carbon resin or resin leaf spring.

  Instead of the holding plates 5 and 7 of the set of vibration control devices 1001, the plate spring 1 has a through hole for the positioning fixing pin 13 at the same position as the three arc centers and a through hole 40 for the rotating shaft. FIG. 19 is a front view of a set of vibration control devices 1005 using the holding plates 35 and 37, and FIG. 20 is a perspective view thereof. The relationship between the XYZ coordinates and the origin O in FIGS. 19 and 20 is the same as that in the above paragraphs 0018, 0020, or 0023, and is therefore omitted.

  A set of vibration control devices 1005 are installed and fixed with bolts 15 and nuts 17 at two corners surrounded by the beam 19 and the column 21, respectively, at the positions of the through holes 40 for the rotating shafts in the holding plates 35 and 37. The connecting tool 39 with a rotation shaft hole is fixed so as to be able to rotate and slide with the rotating shaft bolt 43 and the same nut 44, and the other end of each connecting device 39 is also fixed to the base fixing member 41 so as to be able to rotate and slide. FIG. 21 is a partial front sectional view showing a state in which the nut 43 and the nut 44 are fixed. As shown in FIG. 21, the right half of the center line connecting the midpoint of the beam 19 and the base (floor) 23 is shown in a sectional view. Further, FIG. 22 is a cross-sectional side view seen from the A1-A1 direction.

  The connecting device 39 can move in a circular arc around the rotating sliding portion of the base fixing member 41, and the position of the rotating portion of the vibration control device 1005 changes accordingly, so that the deformation of the leaf spring 1 is greatly taken into account. As a result, the restoring force against the earthquake is increased, and the damping force of the cylindrical rubber 3 is increased along with the deformation of the leaf spring, so that the shaking with respect to the earthquake is reduced. Further, the material of the leaf spring shown in the embodiment is not particularly made of metal, and may be made of carbon fiber reinforced plastic, carbon resin or resin.

The positive direction (+) is orthogonal to the X coordinate direction, and the center side of the arc is the positive direction (+) of the Y coordinate. Figure 36 is an inner diameter vibration damping cylinder rubber 81 which is suitable for arc R ₃₁ and guide rollers 87 and the arc for a cylindrical rubber 83 of the inner diameter R ₃₂ and guide rollers 89 of the continuous arc bending the leaf spring 79, the inner diameter R The positional relationship between the ₃₃ circular arc cylindrical rubber 85 and the guide roller 91 is shown. Here, in the case of R ₃₁ = R ₃₂ = R ₃₃ , the shape connecting the center points of these arcs is a right-angled isosceles triangle, but the damping device for installing and fixing the straight portion of the leaf spring 79 to the beam 19 The + direction of the Y coordinate shown in FIG. 35 is the direction from the beam 19 toward the base (floor) 23, but the shape connecting the three arc centers of the leaf spring 79 is an isosceles triangle or an equilateral triangle.

A front view of a set of vibration control devices 1011 that are positioned by the fixing pins 13 and the retaining ring 11 and fixed to the beam so as to be sandwiched between the holding plates 93 and 95 is shown. Is provided with a through hole 101 for fixing the base connecting device 99. FIG. 38 is a perspective view of the set of vibration control devices 1011. The relationship of the XYZ coordinates of the set of vibration control devices 1011 is the straight line portion (x0-x1) described in paragraph 0034 above. And a plane including the surface of the holding plate 95 including the through hole at the same position as the triangle connecting the three arc centers of the leaf spring 79 and perpendicular to the X coordinate plane including (x2-x3) 79. The end point x0 of 79 is orthogonal to the X coordinate direction and the Y coordinate direction, and is parallel to the length direction of the fixing pin 13, and the direction from the holding plate 95 to 93 is defined as the positive direction (+) of the Z coordinate. Yes. The same applies to the XYZ coordinate relationship of a set of vibration control devices for beams in the following embodiments.

  FIG. 39 shows a base fixture in which the set of vibration control devices 1011 is fixed to the center of the lower part (base side) of the beam 19 with bolts 15 and nuts 17 and is installed and fixed to the base (floor) 23 with bolts 15 and nuts 17.

As shown in FIG. 41, the leaf spring 79 used in the set of vibration control devices 1011 is deformed by the relative displacement of the beam 19 and the base (floor) 23 caused by the earthquake and is caused by the leaf spring 79. The relative displacement between the beam 19 and the base (floor) 23 is reduced by the damping effect of the vibration damping cylindrical rubbers 81, 83, 85 sandwiched between the holding plates 93 and 95 together with the restoring force. The cylindrical rubbers 81, 83, 85 are the same as the arc centers obtained by bending the leaf springs 79 with the inner diameters R ₃₁ , R ₃₂ , R ₃₃ by the guide rollers 87, 89, 91 inserted inside the cylindrical rubbers. It is sandwiched between holding plates 93 and 95 having through holes formed at positions and positioned by pins 13 to maintain a certain triangular shape. For this reason, the movement of the set of vibration control devices 1011 causes a left-right swing accompanied by a rotational movement about the arc center of the inner diameter R ₃₂ of the leaf spring 79. For example, when the beam 19 is displaced relative to the base (floor) 23 to the right in FIG. 41, the leaf spring 79 is deformed in the direction of compressing the cylindrical rubbers 83 and 85 among the three arcs of the leaf spring 79. On the contrary, when opposed to the left side of FIG. 41, the leaf spring 79 is deformed in the direction in which the cylindrical rubbers 81 and 83 are compressed, and a force for damping the vibration acts accordingly.

The relationship between the inner diameters of the overlapping arcs is R ₈₁ = R ₉₁ + t = R ₁₀₁ + 2 × t, R ₈₂ = R ₉₂ −t = R ₁₀₂ −2 × t, R ₈₃ = R ₉₃ + t = R ₁₀₃ Since there is a relationship of + 2 × t and the respective leaf springs are not bonded or fixed, friction between the plates occurs in the deformation at the time of shaking of the earthquake, so that the vibration damping effect can be improved.

FIG. 70 shows a cylindrical rubber that is brought into close contact with three circular arcs that are formed when the leaf springs 155, 157, and 159 are stacked, and a guide roller that is inserted inside the cylindrical rubber.

Although one set of vibration control devices 1023 shows a triple leaf spring structure, it is naturally possible to use two or more leaf springs in a stacked manner, and the effect of the spring constant of the whole of the stacked leaf springs Since it is possible to improve the damping effect due to the friction between the leaf springs of each leaf spring, the triple leaf spring structure is not particular. For example, in the case of an n-fold leaf spring structure, leaf springs 1, 2, 3,..., K,..., N (k ≧ 2, n ≧ k, n, k: integer) and Then, the plate spring k of the k-th thickness t, the linear portion (m-m), bend counterclockwise arc of the inner diameter R _k1, bent clockwise arc of the inner diameter R _k2, the counterclockwise direction R _k3 Molded with a configuration consisting of an arc bend and a straight part (nn),
R _k1 = R ₁₁ − (k−1) × t, R _k2 = R ₁₂ + (k−1) × t, R _k3 = R ₁₃ − (k−1) × t
It is a positive number (R _k1 > 0, R _k2 > 0, R _k3 > 0) having the following relationship.
