Description

本発明は、木造建物の縦材と横架材で囲まれた開口部に設ける木造建物用制震ダンパー装置、およびその木造建物用制震ダンパー装置を用いた木造建物に関する。 The present invention relates to a seismic damper device for a wooden building installed in an opening surrounded by vertical members and horizontal members of a wooden building, and a wooden building using the seismic damper device for a wooden building.

従来の木造建物用制震ダンパー装置として、例えば、離間した一対の縦材および横架材とに囲まれた開口部における横架材に可動板と固定板との間に高減衰ゴムを設けた制震ダンパー機構部を固定する一方、縦材にアーム取付金物を固定し、制震ダンパー機構部の可動板とアーム取付金物とを長尺のアームで連結した構造がある（例えば、特許文献１参照）。この装置では、地震等によって開口部が変形した際、制震ダンパー機構部の可動板が固定板に対し回動し、その回動エネルギーを高減衰ゴムで吸収するように構成している。 As a conventional vibration control damper device for a wooden building, for example, a high damping rubber is provided between a movable plate and a fixed plate in a horizontal frame member at an opening surrounded by a pair of spaced vertical members and a horizontal frame member. There is a structure in which the vibration control damper mechanism is fixed, and the arm mounting hardware is fixed to the vertical member, and the movable plate of the vibration control damper mechanism and the arm mounting hardware are connected by a long arm (for example, Patent Document 1 reference). In this device, when the opening is deformed due to an earthquake or the like, the movable plate of the seismic damper mechanism rotates relative to the fixed plate, and the rotational energy is absorbed by high-damping rubber.

Contact with or close to the upper surface (inner surface).

これに対し、第１長尺部材１１、第２長尺部材１２および第３長尺部材１３の横方向の重なり具合は、図１１（ｂ）におけるＥ－Ｅ線部分では、第２長尺部材１２は側板部１２ｂ，１２ｂがないため大きな隙間が空くが、図１１（ｂ）におけるＦ－Ｆ線部分の第２長尺部材１２の長尺側板部１２ｂ１，１２ｂ１がある箇所でも、第１長尺部材１１の側板部１１ｂ，１１ｂと第３長尺部材１３の側板部１３ｂ，１３ｂとの間に第２長尺部材１２は側板部１２ｂ，１２ｂの厚さ以上の隙間が空くようにしている。 On the other hand, the degree of lateral overlapping of the first elongated member 11, the second elongated member 12, and the third elongated member 13 is as follows: 12 does not have the side plate parts 12b, 12b, so there is a large gap, but even in the part where the long side plate parts 12b1, 12b1 of the second long member 12 in the line FF in FIG. The second elongated member 12 has a gap greater than the thickness of the side plate portions 12b, 12b between the side plate portions 11b, 11b of the elongated member 11 and the side plate portions 13b, 13b of the third elongated member 13. .

図１３（ａ），（ｂ）は、それぞれ図２（ａ）におけるＡ部分の溶接状態を示す拡大端面図、図２（ｃ）におけるＢ部分の溶接状態を示す拡大端面図である。 13(a) and 13(b) are an enlarged end view showing the welded state of portion A in FIG. 2(a) and an enlarged end view showing the welded state of portion B in FIG. 2(c), respectively.

図２（ａ）におけるＡ部分において第１長尺部材１１～第３長尺部材１３の背板部１１ａ～１３ａ側では、図１３（ａ）に示すように、第１長尺部材１１の背板部１１ａ上面に対し第２長尺部材１２の背板部１２ａ先端部および第３長尺部材１３の背板部１３ａ先端部が隠れるように隅肉溶接等によって接合する。図１３（ａ）における１６ａが、その溶接部である。 At the back plate portions 11a to 13a of the first to third elongated members 11 to 13 in part A in FIG. 2(a), as shown in FIG. They are joined by fillet welding or the like so that the tip of the back plate 12a of the second elongated member 12 and the tip of the back plate 13a of the third elongated member 13 are hidden from the upper surface of the plate 11a. 16a in FIG. 13(a) is the welded portion.

また、図２（ａ）におけるＡ部分において第１長尺部材１１～第３長尺部材１３の背板部１１ａ～１３ａ側とは反対側となる第１長尺部材１１の側板部１１ｂ，１１ｂ下端部と、第２長尺部材１２の側板部１２ｂ，１２ｂ下端部と、第３長尺部材１３の底板部１３ｃとも、それぞれ、図１３（ａ）に示すように隅肉溶接等により溶接して接合する。図１３（ａ）における１６ｂ，１６ｂが、その溶接部である。 Further, side plate portions 11b, 11b of the first elongated member 11, which are opposite to the back plate portions 11a to 13a of the first elongated member 11 to third elongated member 13 in the A portion in FIG. The lower end portion, the lower end portions of the side plate portions 12b, 12b of the second elongated member 12, and the bottom plate portion 13c of the third elongated member 13 are each welded by fillet welding or the like as shown in FIG. 13(a). and join. 16b and 16b in FIG. 13(a) are the welded parts.

つまり、図２（ａ）におけるＡ部分では、第１長尺部材１１～第３長尺部材１３の上下で第１長尺部材１１～第３長尺部材１３の３部材を共に接合する。尚、本発明では、図１３（ａ）に示す溶接部１６ｂ，１６ｂは、省略することができる。 That is, in part A in FIG. 2(a), the three members of the first to third elongated members 11 to 13 are joined together above and below the first to third elongated members 11 to 13. Note that in the present invention, the welded portions 16b, 16b shown in FIG. 13(a) can be omitted.

一方、図２（ｃ）におけるＢ部分では、図１３（ｂ）に示すように第１長尺部材１１の側板部１１ｂ，１１ｂ下端部と第３長尺部材１３の底板部１３ｃとの間でのみ、例えば、点付溶接等によりスポット的に溶接を行う。図１３（ｂ）における１６ｃ，１６ｃが、その溶接部である。尚、本発明では、図２（ｃ）におけるＢ部分における第１長尺部材１１と第３長尺部材１３との間の溶接は、省略することができる。 On the other hand, in part B in FIG. 2(c), as shown in FIG. For example, spot welding is performed by spot welding or the like. 16c and 16c in FIG. 13(b) are the welded parts. In addition, in the present invention, welding between the first elongated member 11 and the third elongated member 13 at the B portion in FIG. 2(c) can be omitted.

つまり、図２（ｃ）におけるＢ部分では、第１長尺部材１１と第３長尺部材１３との間でのみ溶接し、伸縮部１２ａ３を有する第２長尺部材１２は、第１長尺部材１１および第３長尺部材１３に溶接しないので、その長手方向に伸縮可能となる。 That is, in the B part in FIG. 2(c), only the first elongated member 11 and the third elongated member 13 are welded, and the second elongated member 12 having the elastic part 12a3 is welded to the first elongated member 12. Since it is not welded to the member 11 and the third elongated member 13, it can be expanded and contracted in the longitudinal direction.

これにより、図２（ａ）におけるＡ部分では、第１長尺部材１１～第３長尺部材１３の全てが接合される一方、図２（ｃ）におけるＢ部分では、第１長尺部材１１と第３長尺部材のみが接合され、第２長尺部材１２は接合されないため、図１等に示すように第１長尺部材１１の基端部１１ｃ側の第１固定部１４と第２長尺部材１２の基端部１２ｃ側の第２固定部１５とをそれぞれ柱２や土台３または梁４等の木材に固定すると、第１長尺部材１１および第２長尺部材１２の双方でブレース材（芯材）を構成することになるので、後述するように第１固定部１４と第２固定部１５との間の間隔が広がったり狭まると、主に第２長尺部材１２の伸縮部１２ａ３が伸縮することになる。 As a result, in part A in FIG. 2(a), all of the first elongated member 11 to third elongated member 13 are joined, while in part B in FIG. 2(c), the first elongated member 11 Since only the third elongated member and the second elongated member 12 are joined, as shown in FIG. When the second fixing portion 15 on the proximal end 12c side of the elongated member 12 is fixed to the pillar 2, the base 3, the beam 4, or other wood, both the first elongated member 11 and the second elongated member 12 Since this constitutes a brace material (core material), when the distance between the first fixing part 14 and the second fixing part 15 widens or narrows as described later, the second elongated member 12 mainly expands and contracts. The portion 12a3 will expand and contract.

また、第３長尺部材１３は、その長手方向の両端部においていずれも第１長尺部材１１と接合されるので、柱２や土台３、梁４等を通じて小さな振動等が木造建物用制震ダンパー装置１に伝達した場合でも、第３長尺部材１３が単独で揺れて他の第１長尺部材１１や第２長尺部材１２に当たって衝突音を発生することを防止することができる。 In addition, since the third elongated member 13 is joined to the first elongated member 11 at both ends in the longitudinal direction, small vibrations etc. can be damped for wooden buildings through the pillars 2, foundations 3, beams 4, etc. Even when the vibration is transmitted to the damper device 1, it is possible to prevent the third elongated member 13 from swinging independently and hitting the other first elongated member 11 or the second elongated member 12, thereby preventing collision noise from being generated.

＜本発明に係る実施形態の木造建物用制震ダンパー装置１の機能＞
次に、以上のように構成された本発明に係る実施形態の木造建物用制震ダンパー装置１の機能について説明する。 <Functions of the vibration control damper device 1 for wooden buildings according to the embodiment of the present invention>
Next, the functions of the vibration control damper device 1 for a wooden building according to the embodiment of the present invention configured as described above will be explained.

例えば、図１に示すように２本の柱２と土台３および梁４とで囲まれた壁となる空間に２組の木造建物用制震ダンパー装置１をそれぞれ取り付け、地震の横揺れ等によって図１４における矢印α方向にせん断力が作用した場合、上側の木造建物用制震ダンパー装置１では、第１固定部１４と第２固定部１５との間の間隔が狭まって、圧縮力が作用することになるので、第２長尺部材１２の伸縮部１２ａ３は収縮してこの壁に作用する外力を吸収する。 For example, as shown in Fig. 1, two sets of vibration control damper devices 1 for wooden buildings are installed in a space that forms a wall surrounded by two pillars 2, a foundation 3, and a beam 4, and When a shear force acts in the direction of the arrow α in FIG. 14, in the upper wooden building seismic damper device 1, the distance between the first fixed part 14 and the second fixed part 15 narrows, and a compressive force acts. Therefore, the expandable portion 12a3 of the second elongated member 12 contracts to absorb the external force acting on this wall.

これに対し、下側の木造建物用制震ダンパー装置１には、図１４における矢印α方向にせん断力が作用した場合、第１固定部１４と第２固定部１５との間の間隔が広がって、引張力が作用することになるので、第２長尺部材１２の伸縮部１２ａ３は伸長してこの壁に作用する外力を吸収して壁の破壊等を防止する。 On the other hand, when a shear force is applied to the lower wooden building vibration control damper device 1 in the direction of the arrow α in FIG. As a result, a tensile force is applied to the wall, and the stretchable portion 12a3 of the second elongated member 12 expands to absorb the external force acting on the wall, thereby preventing the wall from being destroyed.

一方、地震の横揺れ等によって図１５に示すように矢印β方向にせん断力が作用した場合、上側の木造建物用制震ダンパー装置１では、第１固定部１４と第２固定部１５との間の間隔が広がって、引張力が作用することになるので、第２長尺部材１２の伸縮部１２ａ３は伸長してこの壁に作用する外力を吸収する一方、下側の木造建物用制震ダンパー装置１では、第１固定部１４と第２固定部１５との間の間隔が狭まって、圧縮力が作用することになるので、第２長尺部材１２の伸縮部１２ａ３は収縮してこの壁に作用する外力を吸収して壁の破壊等を防止する。 On the other hand, when a shearing force acts in the direction of the arrow β as shown in FIG. Since the gap between the walls is widened and a tensile force is applied, the elastic part 12a3 of the second elongated member 12 expands and absorbs the external force acting on this wall. In the damper device 1, the distance between the first fixed part 14 and the second fixed part 15 is narrowed, and compressive force is applied to the elastic part 12a3 of the second elongated member 12.
