In addition, before the work of inserting the core member 11 into the space 50, as shown in FIGS. 9 and 10, a clearance material (unbonded material) for preventing solidified mortar from adhering to the core member 11 is obtained. The material 52 is applied to the outer surface of the core member 11.

Further, in the present embodiment, as shown in FIG. 11, which is a cross-sectional view taken along the line S11-S11 of FIG. 4, in the base member 1 whose cross-sectional shape is the above-described quadrangle, the length direction of the base member 1 Among the dimensions in the two directions orthogonal to, the width dimension W1 in the horizontal width direction and the two dimensions orthogonal to the length direction of the column member 3 in the column member 3 having a quadrangular cross-sectional shape. Among these dimensions, the width dimension W2 in the horizontal width direction is the same or substantially the same. Further, of these width dimensions W1 and W2 and the dimensions of the restraint member 12 having a quadrangular cross section in two directions orthogonal to the length direction of the restraint member 12, the width dimension W3 in the width direction. In other words, the spacing dimension W3 between the above-mentioned two surface contact portions 12A and 12B of the restraint member 12 is the same or substantially the same. The width W1 of the base member 1 is the same as that of the beam member 2 of FIG. 4 having a quadrangular cross section, and the width W2 of the column member 3 is quadrangular in cross section. The same applies to the pillar member 4 in FIG.

Further, the width direction of the base member 1 described above, the width direction of the beam member 2, and further the width direction of the pillar members 3 and 4 are in the direction perpendicular to the inner surface of the rectangular frame 8 shown in FIG. This is also the direction of the thickness of the core member 11, which is the main member of the vibration damping device 10.

Therefore, the dimension of the restraint member 12 in the direction perpendicular to the width direction of the width dimension W3 is the same as or substantially the same as the dimension of the column members 3 and 4 in the lateral direction perpendicular to the width direction of the width dimension W2. By doing so, the restraint member 12 can be easily formed by cutting a square bar made of the same material as the pillar members 3 and 4 in the same length dimension as the restraint member 12.

Further, by making the dimension of the restraint member 12 in the direction perpendicular to the width direction of the width dimension W3 the same as or substantially the same as the vertical dimension perpendicular to the width direction of the width dimension W1 of the beam member 2, the restraint member 12 can be easily formed by cutting a square bar made of the same material as the beam member 2 in the same length dimension as the restraining member 12.

Further, the height dimension of the base member 1 is different from the left-right dimension in the horizontal direction perpendicular to the width direction of the width dimension W2 of the pillar members 3 and 4, but the width dimension of the width dimension W3 of the restraining member 12 is different. By making the dimension in the direction perpendicular to the same as or substantially the same as the height dimension of the base member 1, the restraint member 12 is a square bar made of the same material as the base member 1 with the same length dimension as the restraint member 12. It can be easily formed by cutting.

Therefore, according to the present embodiment, the restraint member 12 is made of the same wood as the base member 1, the beam member 2, and the pillar members 3 and 4 which are the above-described four rod-shaped members forming the rectangular frame 8. Since the restraint member 12 can be formed, and the cross-sectional shape of the restraint member 12 is the same quadrangle as the cross-sectional shape of the base member 1, the beam member 2, and the pillar members 3 and 4, the length of the restraint member 12 in the restraint member 12 is long. Of the dimensions in the two directions orthogonal to the vertical direction, at least one dimension is orthogonal to the longitudinal direction of each of the base member 1, the beam member 2 and the column members 3 and 4 of these members 1 to 4. By making the size of the constraining member 12 the same as or substantially the same as at least one of the dimensions in the two directions, the restraint member 12 is made to have a material and a cross-sectional shape in relation to the base member 1, the beam member 2, and the pillar members 3 and 4. Since the dimensions can be made common, the vibration damping device 10 can be manufactured while keeping the manufacturing cost of the restraint member 12 low.

In addition, as shown in FIG. 11, the core member 11 of the vibration damping device 10 is located at a central portion or a substantially central portion in the width direction of the width dimension W1 of the base member 1 and the beam member 2, and is a pillar. Since it is required to dispose the members 3 and 4 at a position which is also a central portion or a substantially central portion in the width direction of the width dimension W2, as can be seen from FIG. 11, both end surfaces of the restraining member 12 in the length direction. Both ends 11A and 11B in the length direction of the core member 11 protruding from the core member 11 overlap with the connecting member 26 of the first gusset plate 21 and the connecting member 36 of the second gusset plate 22 in the thickness direction of the core member 11. In the case of the present embodiment in which the first and second gusset plates 21 and 22 are bent, as shown in FIGS. 6 and 7, the connecting members 26 and 36 are bent. The members 25 and 35 are not arranged at the central portion or substantially central portion in the width direction, and the distance W4 is from one end portion of both end portions of the bending members 25 and 35 in the width direction, At a position at a distance W5 from the other end, that is, at a position deviated from the center or substantially the center in the width direction of the bending members 25, 35, the connecting members 26, 36 have the first and second gussets. It is connected to the bending members 25 and 35 of the plates 21 and 22 by welding. These distances W4 and W5 are also shown in FIG.

The vibration damping device 10 according to the present embodiment is housed inside the wall 55 as shown in FIGS. 1 and 3, and therefore, as shown in FIGS. 9 and 10. The constraining member 12 is disposed inside the above-mentioned rectangular frame 8 in a state of being sandwiched between two wall surface members 57 and 58 forming both sides in the thickness direction of the wall 55. In FIG. 1 and FIG. 3, of these wall surface members 57, 58, for example, the wall surface member 57 that is an indoor surface member and is made of gypsum board is used. The nail 56 which is a fastener for fixing to the No. 5 is shown, and the wall surface member 58 which is an outdoor surface member and is formed of a siding boat or the like is also shown in the drawing. Although not attached, it is fixed to the pillar members 3 to 5 by a nail which is a fixing tool.

As shown in FIGS. 9 and 10, the wall surface members 57 and 58 are surface contact which are outer surfaces on both sides of the restraint member 12 in a direction orthogonal to the length direction of the restraint member 12. The wall surface member 57 is in surface contact with the portions 12A and 12B, the wall surface member 57 is fixed to the surface contact portion 12A by a nail 59 that is a fastener, and the wall surface member 58 is a fastener. The nails 60 are fixed to the surface contact portion 12B, and as shown in FIG. 3, a plurality of these nails 59 and 60 are driven in at equal intervals in the length direction of the restraining member 12.

Further, as shown in FIGS. 9 and 10, the nails 59 and 60 are provided inside the restraint member 12 with a circular cross-sectional shape in the direction orthogonal to the length direction of the restraint member 12. At a position radially displaced from the center of this circular shape of the space 50, in the embodiment of FIGS. 9 and 10, at a position near the upper end of the restraint member 12 and at a position near the lower end of the restraint member 12. The wall surface members 57 and 58 are driven into the restraining member 12.

As described above, the outer surface of the restraint member 12 of the present embodiment is provided with the surface contact portions 12A and 12B with which the surface members 57 and 58 for wall contact, and the surface members for wall 12A and 12B. Since 57 and 58 are fixed by the nails 59 and 60, the intermediate column member and the horizontal crosspiece are interfered with by the vibration damping device 10 inside the rectangular frame 8 in which the vibration damping device 10 is arranged. And the like, the wall surface members 57, 58 can be attached to the restraining member 12 which is a constituent member of the vibration damping device 10, and thus the wall surface members 57, 58 can be attached. It is possible to effectively prevent the 58 from flexing and deforming in the thickness direction of the wall 55.

Further, the wall surface members 57, 58 are constrained by the nails 59, 60 at positions radially displaced from the center of the circle 50 of the space 50 provided in the constraining member 12 with a circular cross-sectional shape. Since the nails 59 and 60 are fixed to the surface contact portions 12A and 12B of the member 12, the nails 59 and 60 can penetrate into the restraining member 12 deep enough to avoid the circular space 50. The attachment strength of the wall surface members 57, 58 to the restraining member 12 by 59, 60 can be increased.

The fasteners for fastening the wall surface members 57, 58 to the surface contact portions 12A, 12B of the restraining member 12 are not limited to the nails 59, 60, and may be staples or screw nails. ..

As shown in FIG. 4, when lateral loads F1 and F2 due to an earthquake or the like act on a building in which the above-described square frame 8 in which the vibration damping device 10 is arranged is partially provided, the square frame is formed. By deforming 8 into a rhombus shape, the length direction becomes a diagonal direction of the quadrangular frame 8, and both ends 11A and 11B in the length direction are quadrangular via the first gusset plate 21 and the second gusset plate 22. A pulling force or a compressive force, which is an axial force, acts on the core member 11 connected to the frame 8, and these axial forces are the constricted portions of the core member 11 which are the plasticizing portions described in FIG. By plastically deforming 11C, the plastic deformation absorbs the vibration energy of the building and suppresses the vibration. Further, when an excessive compressive force is applied to the core member 11, the core member 11 is in the thickness direction of the core member 11, which is a direction that makes an angle with the length direction of the core member 11, that is, the above-mentioned wall. Although the buckling deformation of 55 is attempted in the thickness direction, this buckling deformation is prevented by the restraining action of the mortar filled as the filler 51 in the space 50 inside the restraining member 12 and the restraining member 12. .. Further, the wall surface members 57 and 58 of the present embodiment are fixed to the pillar members 3 to 5 by the nails 56 and also fixed to the restraining member 12 by the nails 59 and 60. The surface members 57 and 58 also absorb the vibration energy of the building and suppress the vibration.

Further, in the present embodiment, as described with reference to FIG. 11, both ends of the core member 11 in the length direction are connected to the connecting members 26 and 36 of the first and second gusset plates 21 and 22 by the thickness of the core member 11. The connecting members 26 and 36 are connected to each other by overlapping in the direction, but as shown in FIGS. 6 and 7, the connecting members 26 and 36 are arranged at the center of the bending members 25 and 35 of the gusset plates 21 and 22 in the width direction. Portion or substantially central portion, and the connecting members 26 and 36 are arranged at positions displaced from the central portion or substantially central portion in the width direction of the bending members 25 and 35, thereby providing the core member. Since 11 is arranged in the central portion or substantially central portion in the width direction of the base member 1, the beam member 2, and the pillar members 3 and 4 which are the four rod-shaped members forming the rectangular frame 8, Vibrations due to lateral loads F1 and F2 acting on the quadrangular frame 8 due to an earthquake or the like can be transmitted to the core member 11 more reliably, whereby the vibration energy of the building is further increased by the plastic deformation of the constricted portion 11C of the core member 11. It can be effectively absorbed and vibration can be effectively suppressed.

Further, according to the present embodiment, the core member 11 is a brace member that is effective for both the tensile force and the compressive force acting as an axial force on the core member 11, so that the core member 11 is restrained inside the rectangular frame 8. By installing the vibration device 10, a brace member having an inclination angle with respect to the horizontal direction opposite to that of the core member 11 of the vibration damping device 10 is provided inside another rectangular frame formed next to the rectangular frame 8. This eliminates the need for arranging it, which simplifies the structure of a building with a wooden frame structure.

Further, when lateral loads F1 and F2 due to an earthquake or the like act on the rectangular frame 8, the upper ends of the column members 3 and 4 shown in FIG. 4 are horizontal to the lower ends of these column members 3 and 4. Since the pillar members 3 and 4 are moved in the direction, an upward pulling force is applied to the pillar members 3 and 4 such that the lower end portion of the pillar member 3 tends to come off. However, the first gusset plate 21 connecting the lower end 11A of the core member 11 to the rectangular frame 8 is connected to the base member 1 by the nail 27 and the horizontal portion 25A and the pillar member 3 by the nail 29. Since the bending member 25 having the rising portion 25B is provided, the first gusset plate 21 prevents the lower end portion of the pillar member 3 from coming off the base member 1 due to the upward pulling force. be able to. The bracket 23 is also a bending member having a horizontal portion 23A joined to the base member 1 with a nail 45 and a rising portion 23B joined to the pillar member 4 with a nail 47. The bracket 23 can prevent the lower end portion from coming off the base member 1 due to an upward pulling force.

Further, the second gusset plate 22 connecting the upper end portion 11B of the core member 11 to the rectangular frame 8 is connected to the beam member 2 by the nail 37 and the horizontal portion 35A and the column member 4 by the nail 39. Since the bending member 35 having the hanging portion 35B is provided, it is possible to prevent the upper end portion of the pillar member 4 from being displaced in the longitudinal direction of the beam member 2 with respect to the beam member 2. It can be blocked by 22.

Further, when the lateral load F1 of the lateral loads F1 and F2 shown in FIG. 4 acts on the quadrangular frame 8, the compressive load acts on the core member 11 of the vibration damping device 10, and the corner portion A is applied to the base member 1. From the corner portion C to the corner portion C, a tensile load acts on the column member 4, and these loads become a closed vector load in the rectangular frame 8, and a lateral load F2 acts on the rectangular frame 8. At this time, a tensile load acts on the core member 11 of the vibration damping device 10, a compressive load acts on the column member 4, and a load directed from the corner C to the corner A acts on the base member 1, Since the load is also a closed vector load in the quadrangular frame 8, among the four corners A to D of the quadrangular frame 8, at the corner B, the beam member 2 forming this corner B is formed. The connection state between the beam member 2 and the column member 3 is secured without disposing a bent member made of a sheet metal bent in an L-shape that is connected to each of the column members 3 with a fastener such as a nail. You can do it. Further, as described above, the beam member 2 and the pillar member 3 are connected by the concave and convex fitting in which the convex portion 3B provided at the upper end portion of the pillar member 3 is fitted into the concave portion 2A formed on the lower surface of the beam 2. Therefore, even if the bent member made of sheet metal bent into an L-shape that is joined to the beam member 2 and the column member 3 by a fastener such as a nail is not disposed at the corner B, this uneven fitting is performed. The connection state between the beam member 2 and the column member 3 can be more reliably ensured by the combination.

Therefore, according to the present embodiment, the bracket 23, which is formed only by the bending member made of sheet metal, has the base member 1 and the pillar member 4 among the four corner portions A to D forming the rectangular frame 8. It may be arranged only at the corner C which is a joint, and need not be arranged at the corner B. Therefore, by reducing the number of brackets 23 and the man-hours for mounting the brackets 23, The overall cost can be reduced. The bracket 23 may be arranged not at the inner corner C of the rectangular frame 8 but at the outer corner C', as shown in FIG.

Further, as described above, the width dimension W2 of the pillar members 3 and 4 to which the wall surface members 57 and 58 are fixed and the interval dimension W3 between the two surface contact portions 12A and 12B of the restraining member 12 are Since they are the same or substantially the same, as shown in FIGS. 9 and 10, the wall surface members 57, 58 are brought into direct contact with the surface contact portions 12A, 12B, and the wall members are fixed by the nails 59, 60. The surface members 57 and 58 can be easily fixed to the surface contact portions 12A and 12B.

When the space dimension W3 is smaller than the width dimension W2, a space member made of solid material or laminated material is provided between the wall surface members 57 and 58 and the surface contact portions 12A and 12B. Thus, the wall surface members 57 and 58 may be fixed to the surface contact portions 12A and 12B with the nails 59 and 60 via the space members.

Further, only one of the wall surface members 57 and 58 may be fixed to only one of the surface contact portions 12A and 12B. Therefore, the number of surface contact portions provided on the restraint member 12 may be one.

FIG. 12 shows a vibration damping device 110 according to the first alternative embodiment. The restraint member 112 of the vibration damping device 110 has a dimension shorter than the length dimension of the restraint member 112, and a plurality of restraint member elements 112A having the same length dimension are restrained by the restraint member 112. It is configured to have a portion which is continuously provided and coupled in the length direction of the. That is, each restraint member element 112A is formed by dividing the restraint member 112 into a plurality of pieces in the lengthwise direction of the restraint member 112, and these restraint member elements 112A are described above. Similar to the restraint member 12 of the embodiment, the restraint member 112 is formed of solid wood or laminated lumber, and the cross-sectional shape of each restraint member element 112A orthogonal to the length direction of the restraint member 112 is a quadrangle. The space 150 (see FIG. 14) formed inside each of the restraint member elements 112A has a circular cross-sectional shape orthogonal to the length direction of the restraint member 112.

In FIG. 13, only the restraint member 112 is shown, and metal closing plates 66 and 67 are arranged on both end faces in the lengthwise direction of the restraint member 112.

The male threaded rod member 68 is inserted through, and nuts 68A are screwed and fastened to both ends of the male threaded rod member 68 protruding from the closing plates 66 and 67. As a result, the closing plates 66, 67 and the respective restraint member elements 112A are continuously connected in the length direction of the restraint member 112 and joined by the joining means 69 by the male screw rod member 68 and the nut 68A.

The core member 11 is inserted into the space 150 formed inside each restraint member element 112A, and both ends in the length direction of the core member 11 are projected from the long holes 70 of the closing plates 66 and 67, and then closed. The plates 66, 67 and the respective restraining member elements 112A are continuously connected to each other in the length direction of the restraining member 112 by a joining means 69, and then, the small holes 71 provided in both the closing plates 66, 67 are formed. Mortar, which is the filler 51, is cast into the space 150 inside each of the restraint member elements 112A from one of the small holes 71, and the air in each space 150 compressed by this cast is applied to the other. It is discharged from the small hole 71. Thereby, the length direction of the core member 11 becomes the length direction of itself, and the inside of the restraint member 112 that covers the outer periphery of the core member 11 serves as a filler while covering the outside of the core member 11. Mortar can be filled.

In addition, even if each of the plurality of restraint member elements 112A is formed of wood, the closing plates 66 and 67 shown in FIG. 13 have a length of the restraint member 112 when the above-described nut 68A is tightened. It functions as a washer for preventing the restraint member elements 112A arranged at both ends in the direction from being depressed by the nut 68A.

A member similar to the closing plates 66 and 67 shown in FIG. 13 is the length of the restraint member 12 when the mortar is placed in the space 50 inside the restraint member 12 of the above-described embodiment shown in FIG. After the mortar, which is temporarily fixed and attached to both end faces in the vertical direction and is cast in the space 50, is solidified, the same members as the closing plates 66 and 67 are removed.

In the restraint member 112 according to the first alternative embodiment shown in FIGS. 12 and 13, the restraint member 112 has a dimension shorter than the length dimension of the restraint member 112, and is continuous in the lengthwise direction of the restraint member 112. Since the plurality of constraining member elements 112A that are provided and coupled are included, it is possible to individually perform the perforating operation for providing the space 150 inside the constraining member 112 for each constraining member element 112A. Therefore, it is possible to facilitate the drilling work.

Similar to the restraint member 112 of the first alternative embodiment, the restraint member 212 also has a dimension shorter than the length dimension of the restraint member 212, and each restraint member 212 has the same length dimension. Since the member elements 212A are connected in series in the lengthwise direction of the restraint member 212, each restraint member element 212A divides the restraint member 212 into a plurality of pieces in the lengthwise direction of the restraint member 212. It is formed in the state where it was formed. Further, each restraint member element 212A is formed of solid wood or lumber made of laminated wood, and the cross-sectional shape of each restraint member element 212A orthogonal to the length direction of the restraint member 212 is a quadrangle, and The space formed inside each restraint member element 212A has a circular cross-sectional shape orthogonal to the length direction of the restraint member 212.

Then, the plurality of restraint member elements 212A that are continuously provided in the lengthwise direction of the restraint member 212 are coupled to each other by an adhesive material. That is, the restraint member element 212A is the same as the restraint member element 112A of the embodiment shown in FIGS. 12 and 13, except that the hole 112B formed in the restraint member element 112A is omitted.

It is possible to manufacture the restraint member 312 that is formed so as to penetrate therethrough.

FIG. 18 shows a restraint member 412 according to the fourth alternative embodiment. The restraint member 412 is composed of a plurality of restraint member elements 412A formed by dividing the restraint member 412 in both the length direction of the restraint member 412 and the direction orthogonal to the length direction.

It is manufactured by arranging a plurality of sets of two restraint member elements 412A joined together in the longitudinal direction of the restraint member 412 and joining the restraint member elements 412A of these sets with an adhesive. .. It should be noted that a work of connecting a plurality of restraint member elements 412A continuously in the length direction of the restraint member 412 and joining them with an adhesive is performed as a pre-work, and the restraint member 412 obtained by this pre-work is long in the length direction. By performing the work of joining the two restraint member elements 412A with the semicircular recesses facing each other with an adhesive as a post-work, the cross-sectional shape orthogonal to the length direction is a quadrangle, It is possible to manufacture the restraint member 412 in which a circular space is formed so as to penetrate therethrough over the entire length.

FIG. 19 shows a restraint member 512 according to the fifth alternative embodiment. The restraint member elements 512A of the restraint member 512 are formed of the same material, have the same size and the same shape as the restraint member elements 412A of the fourth embodiment.

The restraint member 512 of this embodiment is manufactured by screwing and tightening the nuts 68A on both ends in the length direction of the male screw rod member 68 projecting from 66A and 67A.

When the restraint member 512 is manufactured in this manner, when a plurality of sets of two restraint member elements 512A are continuously arranged in the length direction of the restraint member 512, each set is bonded with an adhesive. Alternatively, the respective sets may be connected by the connecting means 69 including the male screw rod member 68 and the nut 68A as described above.
