  Furthermore, in the present embodiment, as described above, the auxiliary pillars 5 and 6 are arranged on the outer side in the left and right direction of the columns 1 and 2 in the front view, but the auxiliary columns are arranged on the inner side in the left and right direction of the columns 1 and 2 in the front view. 5 and 6 may be arranged, and the nails 24 and 39 may have a length that reaches the support columns 1 and 2 through the auxiliary columns 5 and 6.

  FIG. 8 shows a state after the brace bracket 13 and the rectangular frame bracket 33 are fixed to the rectangular frame 7. While FIG. 1 is a front view, FIG. 8 which is a cross-sectional view taken along line S8-S8 in FIG. 1 is a side view which is a right angle view from a direction perpendicular to the front view. As shown in FIG. 8, these brackets 13 and 33 have portions overlapping each other in this side view. However, the brace bracket 13 in the front view is as described in FIG. In addition, a rectangular space portion S is formed between the rectangular frame 7 and the square frame bracket 33 is arranged in the space portion S. The two brackets 13 and 33 do not interfere with each other.

  Since the brace bracket 13 and the square frame bracket 33 have portions overlapping each other in a side view, the brace bracket 13 and the square frame bracket 33 in the depth direction in the front view. Thus, the connecting strength of the brace 12 to the square frame 7 by the brace bracket 13 and the support columns 1, 2, the upper frame member 3, and the lower frame member 4 by the square frame bracket 33 can be increased. Bond strength can be increased.

  The quadrangle frame 7 shown in front view in FIG. 1 is a part of a building by the two-by-four method as described above. Therefore, among the components constituting the quadrangle frame 7, the quadrangle frame 7 is disposed to face each other vertically. A middle pillar 45 is provided between the upper frame member 3 and the lower frame member 4 which are the two members. In order to increase the strength of the quadrangular frame 7, the middle pillar 45, which is a bridging member spanned between the upper frame member 3 and the lower frame member 4, includes the columns 1, 2, the upper frame member 3, Like the lower frame member 4 and the supporting pillars 5 and 6, it is made of wood, and the middle pillar 45 is coupled to the upper frame member 3 and the lower frame member 4 by nailing. As shown in FIG. 1, the arrangement position of the middle pillar 45 inside the quadrangular frame 7 is the center position between the left and right support columns 1 and 2, so that the distance between these support columns 1 and 2 is set to L1. In this case, the middle pillar 45 is disposed at a position separated from the pillars 1 and 2 by a dimension L2 that is half of L1, and when L1 is 910 mm, L2 is 455 mm.

  As described above, when the middle pillar 45 is arranged at the center position between the left and right support columns 1 and 2, the vibration control device 11 of the vibration control device 10 is positioned at the center position in the vertical direction and the horizontal direction of the rectangular frame 7 as described above. Therefore, as shown in FIG. 1, in the front view, a part of the middle pillar 45 becomes an overlapping portion overlapping the vibration control device 11.

  For this reason, as shown in FIG. 3, the middle pillar 45 of the present embodiment is provided with an interference avoidance unit 46 for avoiding interference with the vibration control device 11, and this interference avoidance unit 46. Is a concave portion 47 formed with a vertical length in order to accommodate the vibration control device 11 in the central portion of the middle column 45 in the vertical direction. 3 is a side view, and this side view is a right angle view from a direction perpendicular to the front view of FIG. For this reason, in the side view, the concave portion 47 is formed in the middle pillar 45 as the interference avoiding portion 46 for preventing the middle pillar 45 from interfering with the vibration control tool 11.

  The concave portion 47 of the present embodiment is a cutout portion 48 formed by cutting out (cutting out) a part of the middle pillar 45. As can be seen from FIG. 1 and FIG. It reaches two surfaces on both sides in the width direction of the middle column 45 in front view, in other words, reaches the side surfaces on both the left and right sides of the middle column 45. As can be seen from FIG. It has a depth in the depth direction from the surface 45A of the middle pillar 45 in view. The middle pillar 45 before the notch 48 is formed is a middle pillar material, and this middle pillar material, which is a material for the bridging member, has the same cross-sectional shape in the length direction. It has a cross-sectional shape and is continuous. At the center in the length direction, which is the middle position in the length direction of the middle pillar material, it reaches two surfaces on both sides in the width direction of the middle pillar material in a front view, and the depth direction from the surface of the middle pillar material. The notch 48 having a depth of 5 is formed by performing notch processing on a part of the material for the middle pillar, so that the material for the middle pillar becomes the middle pillar 45 and the notch 48 is used for vibration suppression. The recess 47 has a vertical length larger than the vertical dimension of the tool 11.

  The dimension in the depth direction of the quadrangular frame 7 shown in front view in FIG. 1 is T shown in FIG. 3, and is a constituent member of the vibration damping device 10 as can be seen from FIG. The vibration control device 11, the brace 12, and the brace bracket 13 are not disposed at the center position N of the dimension T in the depth direction. From the center position N, the center pillar 45, which is the surface of the above-described center pillar material, is provided. It is arranged at a position shifted to the surface 45A side. Therefore, the middle pillar 45 is formed with a notch 48 having a depth from the surface 45A of the middle pillar 45, and the notch 48 is a recess 47 in which the damping device 11 can be accommodated. In addition, with a simple configuration in which the notch 48 is provided in the middle column, the middle column 45 can be disposed on the quadrangular frame 7 without interfering with the vibration control device 11 in a side view.

  FIG. 4 shows a perspective view of the central portion of the middle pillar 45 in the length direction. On the two side surfaces 45B and 45C which are two surfaces on both sides in the width direction of the middle column 45 in front view, that is, on the two side surfaces 45B and 45C on the left and right sides of the middle column 45 are plate-shaped reinforcing members. 50 are coupled (see also FIG. 2). These reinforcing members 50 are made of a metal such as steel having a strength higher than that of the wooden middle pillar 45, and each reinforcing member 50 has a length dimension in the length direction of the middle pillar 45 including the notch 48. Further, each reinforcing member 50 is formed with a recess 51 having the same shape as the notch 48 at a location corresponding to the notch 48. Each reinforcing member 50 is coupled to the middle column 45 by a fastener 52 such as a nail.

  For this reason, according to the present embodiment, the reinforcing member 50 ensures the strength of the middle pillar 45 even when the notch 48 as the recess 47 for housing the vibration control device 11 is formed in the wooden middle pillar 45. Thus, the strength of the quadrangular frame 7 can be improved by the middle pillar 45 as predetermined.

  FIG. 9 shows the vibration damping tool 11 of the vibration damping device 10 when a lateral load due to an earthquake or the like is applied to the rectangular frame 7. The deformation of the rectangular frame 7 due to the lateral load is transmitted to the vibration control device 11 through the brace brackets 13 and the braces 12 described above, and the vibration control device 11 is shown in FIG. By plastically deforming into a rhombus shape or a substantially rhombus shape when viewed from the front, vibration energy due to the deformation of the quadrangular frame 7 is absorbed by the vibration control tool 11 and the vibration of the quadrangular frame 7 is suppressed.

  Thus, even if the vibration control device 11 is plastically deformed into a rhombus shape or a substantially rhombus shape when viewed from the front, the cutout portion 48 of the middle pillar 45 and the recess portion 51 of the reinforcing member 50 are larger than the vertical dimension of the vibration control device 11. Since it has a large vertical length, the damping device 11 after plastic deformation can be housed inside the notch 48 and the recess 51 as before plasticization. It is possible to prevent the vibration damping device 11 from interfering with the middle column 45 and the reinforcing member 50 before and after plastic deformation of the vibration device 11.

  Further, in the present embodiment, as shown in FIG. 6A, the aforementioned brace bracket 13 for connecting the brace 12 of the vibration damping device 10 to the rectangular frame 7 is provided in the aforementioned hole 29A. In addition to this, a hole 29B is also provided at a location shifted vertically from the hole 29A.
