Description

本発明は、建築物を耐震補強するブレース材（筋交い材）として機能するロープを支持するための支持ユニット、及びブレース材として上記ロープを用いたロープ耐震ユニットに関する。 The present invention relates to a support unit for supporting a rope that functions as a brace material (bracing material) for seismic retrofitting a building, and a rope seismic unit using the rope as a brace material.

木造建築物や軽量鉄骨造の建築物を補強するために、建築物の柱間や梁間に対角線に沿ってブレース材を設置することが一般的に行われている。ブレース材を設置することによって、建築物の水平方向の揺れに対する強度を高めることができる。ブレース材には木製や金属製等、湾曲や屈曲しない硬質の材料を用いることが多いが、近年では、自在に湾曲や屈曲させることが可能であって充分な引っ張り強度を有した線状の材料（線材）が用いられている。
特許文献１には、線材から成るブレース材としてワイヤロープを用いた建築構造体の補強部材が記載されている。この補強部材は、矩形状の建築構造体の対角部分に取り付けられる１組の連結取付部材と、各連結取付部材に対してボルトにより建築構造体の対角線と直交する軸線を中心として回転自在に夫々支持される羽子板部材と、軸方向の一端部が一方の羽子板部材に接続されるターンバックルと、長手方向の一端部がターンバックルの軸方向の他端部に固定され、長手方向の他端部が他方の羽子板部材に固定されるワイヤロープとを備えている。
特許文献１において、羽子板部材はボルトにより対角線と直交する軸線を中心として回転自在に支持されており、ワイヤロープの張設角度が対角線の角度に合わせて変更可能に構成されている。 In order to reinforce wooden buildings and lightweight steel-framed buildings, it is common practice to install brace materials diagonally between columns and beams of the building. By installing the brace material, it is possible to increase the strength against the horizontal shaking of the building. Hard materials that do not bend or bend, such as wood or metal, are often used as the brace material, but in recent years, linear materials that can be freely bent or bent and have sufficient tensile strength. (Wire) is used.
Patent Document 1 describes a reinforcing member of a building structure using a wire rope as a brace material made of a wire rod. This reinforcing member is rotatably centered on a set of connecting mounting members attached to diagonal portions of a rectangular building structure and an axis orthogonal to the diagonal line of the building structure by bolts to each connecting mounting member. A battledore member supported by each, a turnbuckle in which one end in the axial direction is connected to one battledore member, and one end in the longitudinal direction are fixed to the other end in the axial direction of the turnbuckle, and the other end in the longitudinal direction. The portion is provided with a wire rope fixed to the other battledore member.
In Patent Document 1, the feather plate member is rotatably supported by bolts about an axis orthogonal to the diagonal line, and the wire rope tensioning angle can be changed according to the diagonal line angle.

また、ワイヤロープを建築物等に設置する際には、ワイヤロープに対して所定の初期張力を与えて緊張させる必要がある。ワイヤロープの張力を調整する部品としてはターンバックルを用いることが一般的であり、特許文献１に記載の補強部材にもターンバックルが用いられている。 Further, when installing the wire rope in a building or the like, it is necessary to apply a predetermined initial tension to the wire rope to make it tense. A turnbuckle is generally used as a component for adjusting the tension of the wire rope, and the turnbuckle is also used for the reinforcing member described in Patent Document 1.

特開２０００－１５４５９３公報Japanese Unexamined Patent Publication No. 2000-154593

特許文献１に記載されているように、構造材に対してブレース材としてのワイヤロープの張設角度を変更できるように構成すると共に、ワイヤロープの張力調整手段としてターンバックルを備える構成とすると、補強部材の部品点数が増大するという問題がある。
本発明はこのような事情に鑑みてなされたものであり、部品点数を削減して構成を簡略化した支持ユニット、及びロープ耐震ユニットを提供することを目的とする。 As described in Patent Document 1, it is assumed that the wire rope is configured so that the tensioning angle of the wire rope as a brace material can be changed with respect to the structural material, and a turnbuckle is provided as a means for adjusting the tension of the wire rope. There is a problem that the number of parts of the reinforcing member increases.
The present invention has been made in view of such circumstances, and an object of the present invention is to provide a support unit and a rope seismic resistance unit having a simplified configuration by reducing the number of parts.

上記の課題を解決するために、本発明は、少なくとも４個の仕口部を有した建築枠体の対角位置に対向配置された２つの前記仕口部に夫々固定されて、前記建築枠体の対角線に沿って張設されるロープの両端部を支持する支持ユニットであって、前記ロープは、捻り及び結び付けが可能な柔軟性を有し、双方の前記支持ユニットは、一つの前記仕口部に固定されるベース部材と、前記ベース部材により前記対角線と交差する回転軸を中心として回転自在に支持されると共に、前記ロープの端部を結びつけ可能な柱状部、及び、該柱状部とは異なる軸方向位置において前記対角線方向に沿って形成された雌ネジ部、を有した回転支持部材と、前記雌ネジ部と螺着する雄ネジ部、及び、該雄ネジ部の一端に固着されると共に前記ロープの端部を固定するロープ固定部、を有したロープ支持部材と、を備え、前記ロープの一端が一方の前記支持ユニットの前記柱状部に固定され、前記ロープの他端が他方の前記支持ユニットの前記ロープ固定部に固定されたときに、前記ロープ支持部材を前記雄ネジ部の軸線周りに回転させることで、前記ロープ支持部材を前記回転支持部材から前記対角線方向に進退させて前記ロープの張力を調整するようにしたことを特徴とする。 In order to solve the above problems, the present invention is fixed to each of two said joints arranged diagonally opposite to each other in a building frame having at least four joints, and the said building frame. A support unit that supports both ends of a rope stretched along the diagonal of the body, wherein the rope has the flexibility to be twisted and tied, and both support units are one of the above-mentioned parts. A base member fixed to the mouth portion, a columnar portion rotatably supported by the base member about a rotation axis intersecting the diagonal line , and a columnar portion to which the end portion of the rope can be connected, and the columnar portion. Is fixed to a rotation support member having a female threaded portion formed along the diagonal direction at different axial positions, a male threaded portion screwed to the female threaded portion, and one end of the male threaded portion. A rope support member having a rope fixing portion for fixing the end portion of the rope is provided , one end of the rope is fixed to the columnar portion of one of the support units, and the other end of the rope is fixed. When the rope support member is fixed to the rope fixing portion of the other support unit, the rope support member is rotated around the axis of the male screw portion so that the rope support member advances and retreats diagonally from the rotation support member. It is characterized in that the tension of the rope is adjusted .

本発明によれば、ロープ支持部材が回転支持部材により対角線方向に出没自在に構成されているので、部品点数を削減でき、構成を簡略化できる。 According to the present invention, since the rope support member is configured to freely appear and disappear in the diagonal direction by the rotation support member, the number of parts can be reduced and the configuration can be simplified.

＜取付板＞
図４は、取付板を示す図であり、（ａ）は正面図であり、（ｂ）は取付孔の選定例を示す正面図である。以下、取付板１３に関しては、枠材１０１へ取り付けたときに枠材１０１の長手方向（又は軸方向）に沿う方向を長手方向とし、枠材１０１の幅方向（又は短手方向）に沿う方向を幅方向として説明する。
各取付板１３には、取付板１３を枠材１０１に対して固定するための、複数の取付孔１５（４つの大径孔１５ａ～１５ｄ）、及び複数の取付孔１７（４つの小径孔１７ａ～１７ｄ）が貫通形成されている。取付孔のうち大径孔１５ａ～１５ｄは、取付板１３の幅方向の中央部に、その長手方向に沿って等間隔で配置されている。取付孔のうち小径孔１７ａ～１７ｄは、取付板１３の中心点Ｏを対称の中心として点対称に配置されている。小径孔１７ａ、１７ｂは長手方向一端部に位置する大径孔１５ａに隣接して配置されており、小径孔１７ｃ、１７ｄは、長手方向他端部に位置する大径孔１５ｄに隣接して配置されている。
取付板１３、１３は、建築枠体１００を構成する枠材１０１に対して、留め具１９（図１（ａ）、図４（ｂ）参照）を用いて固定される。本例における留め具１９には、引き抜き方向に対して所定の耐力を持つコーススレッドや木ネジ等の固定ネジが用いられる。取付板１３、１３は、取付孔１５、１７を介して留め具１９を枠材１０１に打ち込む（ねじ込む）ことにより枠材１０１に対して固定される。
図４（ｂ）に示すように、１つの枠材１０１ａの表裏両面に（背中合わせとなる位置に）取付板１３Ａ、１３Ｂを取り付ける場合は、両取付板１３Ａ、１３Ｂを枠材１０１ａに固定する留め具１９が互いに重ならない（干渉しない、或いは、互いの締結力に影響を与えない）位置となるように、留め具１９を打ち込む取付孔１５、１７を選定する。
例えば、枠材１０１ａの一面（表面、図中左側面）に固定される取付板１３Ａでは、長手方向の一端部に位置する大径孔１５ａと、これと一つ間を空けた位置にある大径孔１５ｃと、長手方向の他端部に位置する小径孔１７ｃ、１７ｄに留め具１９を打ち込む。また、枠材１０１ａの反対面（裏面、図中右側面）に固定される取付板１３Ｂでは、長手方向の他端部に位置する大径孔１５ｄと、これと一つ間を空けた大径孔１５ｂと、長手方向の一端部に位置する小径孔１７ａ、１７ｂに留め具１９を打ち込む。このようにすることで表裏の位置関係にある留め具１９同士が干渉せず、枠材１０１ａの表裏両面において取付板１３Ａ、１３Ｂの固定に必要な固定力を確保することができる。
図２、図３に示すように、２つの取付板１３、１３はベース部材１１内で離間して配置されているため、ベース部材１１を建築枠体１００の仕口部１０３に取り付けたときに、２つの取付板１３、１３は建築枠体１００の交差部１０５（図１（ａ）参照）には接触しないように取り付けられる。 <Mounting plate>
4A and 4B are views showing a mounting plate, FIG. 4A is a front view, and FIG. 4B is a front view showing an example of selecting a mounting hole. Hereinafter, with respect to the mounting plate 13, the direction along the longitudinal direction (or axial direction) of the frame member 101 when attached to the frame member 101 is defined as the longitudinal direction, and the direction along the width direction (or the lateral direction) of the frame member 101. Will be described as the width direction.
Each mounting plate 13 has a plurality of mounting holes 15 (four large diameter holes 15a to 15d) and a plurality of mounting holes 17 (four small diameter holes 17a) for fixing the mounting plate 13 to the frame material 101. ~ 17d) is formed through. Of the mounting holes, the large-diameter holes 15a to 15d are arranged at the center of the mounting plate 13 in the width direction at equal intervals along the longitudinal direction thereof. Of the mounting holes, the small diameter holes 17a to 17d are arranged point-symmetrically with the center point O of the mounting plate 13 as the center of symmetry. The small diameter holes 17a and 17b are arranged adjacent to the large diameter hole 15a located at one end in the longitudinal direction, and the small diameter holes 17c and 17d are arranged adjacent to the large diameter hole 15d located at the other end in the longitudinal direction. Has been done.
The mounting plates 13 and 13 are fixed to the frame material 101 constituting the building frame body 100 by using fasteners 19 (see FIGS. 1 (a) and 4 (b)). For the fastener 19 in this example, a fixing screw such as a course thread or a wood screw having a predetermined yield strength with respect to the pulling direction is used. The mounting plates 13 and 13 are fixed to the frame material 101 by driving (screwing) the fastener 19 into the frame material 101 via the mounting holes 15 and 17.
As shown in FIG. 4B, when mounting the mounting plates 13A and 13B on both the front and back surfaces of one frame material 101a (at positions that are back to back), the fasteners for fixing both the mounting plates 13A and 13B to the frame material 101a are fastened. The mounting holes 15 and 17 for driving the fasteners 19 are selected so that the tools 19 do not overlap each other (do not interfere with each other or affect the fastening force of each other).
For example, in the mounting plate 13A fixed to one surface (surface, left side surface in the drawing) of the frame member 101a, a large-diameter hole 15a located at one end in the longitudinal direction and a large hole 15a at a position separated from the large-diameter hole 15a. The fastener 19 is driven into the diameter hole 15c and the small diameter holes 17c and 17d located at the other end in the longitudinal direction. Further, in the mounting plate 13B fixed to the opposite surface (back surface, right side surface in the drawing) of the frame member 101a, a large diameter hole 15d located at the other end in the longitudinal direction and a large diameter having one space between them. Fasteners 19 are driven into the holes 15b and the small diameter holes 17a and 17b located at one end in the longitudinal direction. By doing so, the fasteners 19 having a positional relationship between the front and back sides do not interfere with each other, and the fixing force required for fixing the mounting plates 13A and 13B can be secured on both the front and back sides of the frame material 101a.
As shown in FIGS. 2 and 3, since the two mounting plates 13 and 13 are arranged apart from each other in the base member 11, when the base member 11 is attached to the joint portion 103 of the building frame 100, The two mounting plates 13 and 13 are mounted so as not to come into contact with the intersection 105 (see FIG. 1A) of the building frame 100.

対向する２つの支持板２１、２１の面内には、回転支持部材３３を回転自在に支持する軸孔（軸支部）２３、２３が貫通形成されている。 <Support plate>
As shown in FIGS. 2 and 3, the support plate 21 is a substantially fan-shaped (or arch-shaped) flat plate, and the end portions 21a and 21b of the support plate 21 in the circumferential direction (arrow D direction in the drawing) are mounting plates. It is connected to each of the end edges 13a and 13b in the width direction of 13 and 13. When the base member 11 is attached to the joint portion 103 of the building frame body 100, the support plate 21 is a portion close to the intersection portion 105 of the building frame body 100 so as not to come into contact with the intersection portion 105 of the building frame body 100. Has a fan-shaped cutout shape.
Shaft holes (shaft support portions) 23, 23 that rotatably support the rotation support member 33 are formed through the planes of the two support plates 21 and 21 facing each other.

＜回転支持部材＞
図２、図３に示すように、本例に示す回転支持部材３３は、中実の円柱体（丸棒）により構成されている。回転支持部材３３の軸線Ｂ方向の両端には、回転支持部材３３よりも大径のフランジ部材３７、３７が固定されている。フランジ部材３７、３７は、ネジ３９、３９により、回転支持部材３３の軸方向両端面に締結されている。
回転支持部材３３の軸方向長は、ベース部材１１の支持板２１、２１間の外寸Ｅ（支持板２１、２１の非対向面間の間隔）と略同等かこれよりもやや大きい長さに設定されている。回転支持部材３３の外径は、回転支持部材３３の軸孔２３、２３に挿通可能な大きさであり、軸孔２３、２３と略同等の大きさに設定されている。回転支持部材３３は、幅方向両端部において支持板２１、２１の軸孔２３、２３によって回転自在に支持される。また、回転支持部材３３は、その軸線が支持板２１、２１の板面と直交するように、２つの支持板２１、２１によって支持される。なお、回転支持部材３３の少なくとも軸方向両端部が円柱状に形成されていれば、回転支持部材３３の軸方向の中間部は角柱状であってもよい。
回転支持部材３３の軸方向の中間部適所には、ロープ支持部材４１を回転支持部材３３の軸線Ｂ方向と直交（交差）する方向（図３中矢印Ｆ方向）に出没自在に支持するネジ穴３５が貫通形成されている。ネジ穴３５は、回転支持部材３３の軸方向中央部から軸方向の一端寄りに偏心した位置に形成されている。
フランジ部材３７、３７は、軸孔２３、２３内を通過不能な形状及び大きさを有する板状の部材である。本例においてフランジ部材３７、３７は、軸孔２３、２３よりも大径の円板状の部材である。フランジ部材３７、３７は、支持板２１、２１の夫々の外側面（支持板２１、２１の非対向面）に添設された状態で、回転支持部材３３の軸方向両端に締結される。即ち、フランジ部材３７、３７は、２つの支持板２１、２１を間に挟んだ状態で、回転支持部材３３の軸方向両端に固定される。フランジ部材３７、３７は、回転支持部材３３が軸孔２３、２３から脱落すること、及び、回転支持部材３３が必要以上に軸線Ｂ方向へ進退することを阻止する。なお、２つのフランジ部材３７、３７の一方は、回転支持部材３３に対して予め溶接等により固定されていてもよい。 <Rotation support member>
As shown in FIGS. 2 and 3, the rotation support member 33 shown in this example is composed of a solid cylindrical body (round bar). Flange members 37, 37 having a diameter larger than that of the rotation support member 33 are fixed to both ends of the rotation support member 33 in the axis B direction. The flange members 37, 37 are fastened to both end faces in the axial direction of the rotation support member 33 by screws 39, 39.
The axial length of the rotary support member 33 is substantially equal to or slightly larger than the outer dimension E (distance between the non-opposing surfaces of the support plates 21 and 21) between the support plates 21 and 21 of the base member 11. It is set. The outer diameter of the rotation support member 33 is a size that can be inserted into the shaft holes 23, 23 of the rotation support member 33, and is set to substantially the same size as the shaft holes 23, 23. The rotation support member 33 is rotatably supported by the shaft holes 23, 23 of the support plates 21, 21 at both ends in the width direction. Further, the rotation support member 33 is supported by two support plates 21 and 21 so that its axis is orthogonal to the plate surface of the support plates 21 and 21. As long as at least both ends of the rotation support member 33 in the axial direction are formed in a columnar shape, the intermediate portion in the axial direction of the rotation support member 33 may be a prismatic shape.
A screw hole that freely supports the rope support member 41 in a direction orthogonal to (intersects) the axis B direction of the rotation support member 33 (arrow F direction in FIG. 3) at an appropriate position in the middle portion in the axial direction of the rotation support member 33. 35 is formed through. The screw hole 35 is formed at a position eccentric from the central portion in the axial direction of the rotation support member 33 toward one end in the axial direction.
The flange members 37, 37 are plate-shaped members having a shape and a size that cannot pass through the shaft holes 23, 23. In this example, the flange members 37, 37 are disk-shaped members having a diameter larger than that of the shaft holes 23, 23. The flange members 37, 37 are fastened to both ends in the axial direction of the rotary support member 33 in a state of being attached to the outer surfaces of the support plates 21 and 21 (non-opposing surfaces of the support plates 21 and 21). That is, the flange members 37, 37 are fixed to both ends in the axial direction of the rotary support member 33 with the two support plates 21 and 21 sandwiched between them. The flange members 37, 37 prevent the rotation support member 33 from falling out of the shaft holes 23, 23, and the rotation support member 33 from moving forward and backward in the axis B direction more than necessary. One of the two flange members 37, 37 may be fixed to the rotation support member 33 in advance by welding or the like.

＜ロープ支持部材＞
ロープ支持部材４１は、ロープの一端を固定するロープ固定部４３と、ロープ固定部４３から突出する雄ネジ部４５とを備える。本例に示すロープ支持部材４１は所謂アイボルトであり、環状のアイ部がロープ固定部４３を構成する。
雄ネジ部４５は、回転支持部材３３のネジ穴３５に螺着する。雄ネジ部４５の軸方向長は、ロープＲに対して初期張力を与えるに足りる長さに設定されている。回転支持部材３３に対するロープ支持部材４１の取付位置はネジ穴３５の形成位置に等しく、回転支持部材３３の軸方向中央部から軸方向の一端寄りに偏心した位置に設定されている。
ロープ支持部材４１は、回転支持部材３３の回転支持部材３３により、回転支持部材３３の軸線Ｂと直交する方向に出没自在に構成されている。即ち、ロープ支持部材４１は、ネジ穴３５内における雄ネジ部４５の回転に伴って、雄ネジ部４５の軸線に沿って矢印Ｆ方向に進退する。
ここで、ロープ支持部材４１は、回転支持部材３３の軸線Ｂを中心として回転支持部材３３と一体に図２中矢印Ｃ方向へ正逆自在に回転する。即ち、ロープ支持部材４１は、回転支持部材３３と一体に回転して雄ネジ部４５の軸線Ｆが建築枠体１００の対角線方向に伸びたとき、ロープ支持部材４１は建築枠体１００の対角線方向に出没する。 <Rope support member>
The rope support member 41 includes a rope fixing portion 43 for fixing one end of the rope, and a male screw portion 45 protruding from the rope fixing portion 43. The rope support member 41 shown in this example is a so-called eyebolt, and an annular eye portion constitutes a rope fixing portion 43.
The male screw portion 45 is screwed into the screw hole 35 of the rotation support member 33. The axial length of the male threaded portion 45 is set to a length sufficient to give an initial tension to the rope R. The attachment position of the rope support member 41 with respect to the rotation support member 33 is equal to the formation position of the screw hole 35, and is set to a position eccentric from the central portion in the axial direction of the rotation support member 33 toward one end in the axial direction.
The rope support member 41 is configured by the rotation support member 33 of the rotation support member 33 so as to be able to appear and disappear in a direction orthogonal to the axis B of the rotation support member 33. That is, the rope support member 41 advances and retreats in the arrow F direction along the axis of the male screw portion 45 as the male screw portion 45 rotates in the screw hole 35.
Here, the rope support member 41 rotates integrally with the rotation support member 33 about the axis B of the rotation support member 33 in the direction of arrow C in FIG. 2 in the forward and reverse directions. That is, when the rope support member 41 rotates integrally with the rotation support member 33 and the axis F of the male screw portion 45 extends in the diagonal direction of the building frame body 100, the rope support member 41 extends in the diagonal direction of the building frame body 100. Infested in.

＜ロープ＞
図１（ａ）に示すように、ロープＲは、支持ユニット１０Ａ、１０Ｂによって張設されたときに、建築枠体１００内でブレース材（筋交い材）として機能する。ロープＲには金属製のワイヤや合成繊維等の人造繊維を用いることができる。ブレース材として機能させる線状の部材としてロープを用いる場合、ロープは湾曲又は屈曲させて適宜束ねてコンパクト化できるので、その運搬が容易になる。特に人造繊維を用いたロープは軽量であり、自在に折り畳むことができるので、現場への搬入が容易となり、作業スペースが限定的な箇所においても施工が可能となる。
ロープＲを構成する人造繊維としては、アラミド繊維（芳香族ポリアミド繊維）、炭素繊維、ガラス繊維、及びポリエステル繊維の少なくとも一つを用いることができる。 <Rope>
As shown in FIG. 1A, the rope R functions as a brace material (bracing material) in the building frame 100 when stretched by the support units 10A and 10B. Artificial fibers such as metal wires and synthetic fibers can be used for the rope R. When a rope is used as a linear member that functions as a brace material, the rope can be bent or bent to be appropriately bundled and made compact, so that the rope can be easily transported. In particular, ropes made of artificial fibers are lightweight and can be folded freely, so they can be easily carried to the site and can be installed even in places where the work space is limited.
As the artificial fiber constituting the rope R, at least one of aramid fiber (aromatic polyamide fiber), carbon fiber, glass fiber, and polyester fiber can be used.

＜使用方法＞
ロープ耐震ユニット１の使用方法について説明する。
まず、図１に示すように、建築枠体１００の対角方向に位置する少なくとも２つの仕口部１０３、１０３にベース部材１１、１１を夫々取り付ける。即ち、ベース部材１１の取付板１３、１３を、互いに直交する２つの枠材１０１、１０１の角隅部の内側面に密着させて、何れかの取付孔１５、１７（図２等参照）から留め具１９（本例では固定ネジ）を枠材１０１、１０１に打ち込むことにより、ベース部材１１を仕口部１０３に固定する。 <How to use>
The method of using the rope seismic unit 1 will be described.
First, as shown in FIG. 1, the base members 11 and 11 are attached to at least two joints 103 and 103 located diagonally in the building frame 100, respectively. That is, the mounting plates 13 and 13 of the base member 11 are brought into close contact with the inner side surfaces of the corners of the two frame members 101 and 101 orthogonal to each other, and the mounting holes 15 and 17 (see FIG. 2 and the like) are used. The base member 11 is fixed to the joint 103 by driving the fastener 19 (fixing screw in this example) into the frame members 101 and 101.

次に、ベース部材１１に回転支持部材３３を取り付ける。即ち、回転支持部材３３の軸方向一端にフランジ部材３７を固定した状態で、回転支持部材３３の軸方向他端部を一方の支持板２１の軸孔２３から挿入して他方の支持板２１の軸孔２３に係止させる。軸孔２３から露出した回転支持部材３３の軸方向他端にフランジ部材３７を固定して、回転支持部材３３を２つの支持板２１、２１の軸孔２３、２３によって、図２中矢印Ｃ方向に回転自在に支持させる。
なお、建築枠体１００の対角線Ａ方向に位置する２つのベース部材１１、１１に夫々取り付けられる回転支持部材３３、３３の互いのネジ穴３５、３５の位置が枠材１０１の幅方向に重ならないように配置する。即ち、一方の回転支持部材３３は、そのネジ穴３５が枠材１０１の幅方向の一端寄り（例えば図１の紙面の奥側）となるようにし、他方の回転支持部材３３は、そのネジ穴３５が枠材１０１の幅方向の他端寄り（例えば図１の紙面の手前側）となるようにする。 Next, the rotation support member 33 is attached to the base member 11. That is, with the flange member 37 fixed to one end of the rotary support member 33 in the axial direction, the other end of the rotary support member 33 in the axial direction is inserted through the shaft hole 23 of one support plate 21 to form the other support plate 21. It is locked in the shaft hole 23. The flange member 37 is fixed to the other end in the axial direction of the rotary support member 33 exposed from the shaft hole 23, and the rotary support member 33 is attached to the rotary support member 33 by the shaft holes 23, 23 of the two support plates 21, 21 in the direction of arrow C in FIG. It is rotatably supported.
The positions of the screw holes 35, 35 of the rotation support members 33, 33 attached to the two base members 11, 11 located in the diagonal A direction of the building frame 100 do not overlap with each other in the width direction of the frame member 101. Arrange like this. That is, one of the rotation support members 33 has a screw hole 35 closer to one end in the width direction of the frame member 101 (for example, the back side of the paper surface in FIG. 1), and the other rotation support member 33 has a screw hole thereof. 35 is located closer to the other end of the frame member 101 in the width direction (for example, the front side of the paper surface in FIG. 1).

続いて、ロープＲの長手方向の一端部を一方の支持ユニット１０Ｂの回転支持部材３３に固定する。ロープＲが人造繊維等、自在に折り畳める柔軟性を有する場合、回転支持部材３３に対するロープＲの固定には、結び目（ノット或いはロープワーク）を利用することができる。
図５（ａ）、（ｂ）は、支持ユニットに対するロープの固定方法を説明する一部断面図である。支持ユニット１０に対してロープＲを結びつけて固定する場合は、地震の発生に伴ってロープＲが緊張と弛緩を繰り返すような場合にも、自然には解けにくい結び方を利用するのが好適である。例えば、図５（ｂ）に示すように、回転支持部材３３に対するロープＲの固定には、もやい結びや二重八の字結び等を利用することができる。ロープＲの固定には、ロープ同士をかしめて固定する固定金具を用いてもよい。
図５（ａ）に示すように、ロープＲの長手方向の他端部もロープＲの一端部と同様に、結び目を作るか、固定金具によりロープ支持部材４１のロープ固定部４３に固定する。
最後に、ロープ支持部材４１の雄ネジ部４５を回転支持部材３３のネジ穴３５に螺着して、ロープＲに対して所定の初期張力を与える。ここで、ロープ支持部材４１の雄ネジ部４５をネジ穴３５に螺着する際には、予め雄ネジ部４５のねじ込み方向とは反対の方向にロープＲを捻っておき、初期張力を満たした段階でロープＲが極力捻れないようにしておくことが望ましい。 Subsequently, one end of the rope R in the longitudinal direction is fixed to the rotary support member 33 of one of the support units 10B. When the rope R has the flexibility to be freely folded, such as artificial fiber, a knot (knot or rope work) can be used to fix the rope R to the rotation support member 33.
5 (a) and 5 (b) are partial cross-sectional views illustrating a method of fixing a rope to a support unit. When tying and fixing the rope R to the support unit 10, it is preferable to use a tying method that is difficult to untie naturally even when the rope R repeatedly becomes tense and relaxed due to the occurrence of an earthquake. .. For example, as shown in FIG. 5B, a bowline, a figure-eight knot, or the like can be used to fix the rope R to the rotation support member 33. For fixing the rope R, a fixing metal fitting for crimping and fixing the ropes may be used.
As shown in FIG. 5A, the other end of the rope R in the longitudinal direction is also knotted or fixed to the rope fixing portion 43 of the rope support member 41 by a fixing bracket in the same manner as one end of the rope R.
Finally, the male screw portion 45 of the rope support member 41 is screwed into the screw hole 35 of the rotary support member 33 to apply a predetermined initial tension to the rope R. Here, when the male screw portion 45 of the rope support member 41 is screwed into the screw hole 35, the rope R is twisted in advance in a direction opposite to the screwing direction of the male screw portion 45 to satisfy the initial tension. It is desirable to prevent the rope R from twisting as much as possible at the stage.

＜効果＞
以上、本実施形態によれば、ロープＲを回転支持部材３３及びロープ支持部材４１によって、回転支持部材３３の軸線Ｂを中心として揺動可能に支持するので、枠材１０１、１０１に対する建築枠体１００の対角線Ａの角度に応じてロープＲの張設方向を自在に調整できる。
本実施形態においては、回転支持部材３３がロープ支持部材４１を出没自在に支持するので、当該部分がロープＲの張力調整手段として機能する。従来の構成に比べてターンバックル（張力調整手段）を省略することができるので、部品点数を削減できる。
張力調整手段としてのロープ支持部材４１は、ロープ耐震ユニット１において１つあれば足りる。従って、一方の支持ユニット１０ＡはロープＲの長手方向の一端部をロープ支持部材４１によって支持し、他方の支持ユニット１０ＢはロープＲの長手方向の他端部を回転支持部材３３によって支持する構成とできる。この場合、支持ユニット１０Ａの回転支持部材３３のネジ穴３５の位置と、他方の支持ユニット１０Ｂのネジ穴３５の位置を枠材１０１の幅方向に重ならないように配置することで、支持ユニット１０Ｂのネジ穴３５とロープＲの長手方向の他端部とが干渉せず、ネジ穴３５によってロープが損傷するという事態を回避できる。
回転支持部材３３のネジ穴３５が回転支持部材３３の軸方向の中心から一方に偏った位置に形成されているので、建築枠体１００に複数（例えば２本）のロープＲを配置する場合であっても、ロープＲの位置を枠材１０１の幅方向にずらすことができ、ロープ同士の干渉によるロープの損傷を防止できる。なお、建築枠体１００に２本のロープＲを配置する使用例としては、建築枠体１００内に配置した１組のロープ耐震ユニット１に２本のロープＲを固定する場合や、建築枠体１００内に配置した２組のロープ耐震ユニット１に夫々ロープＲを固定して建築枠体１００内にＸ字状にロープＲを配置する場合等が考えられる。回転支持部材３３の軸方向に複数のネジ穴３５を形成して、枠材１０１の幅方向に３本以上のロープＲを配置できるようにしてもよい。
上記実施形態においては、回転支持部材３３を中実棒状としたが中空筒状としてもよい。この場合、回転支持部材３３を軽量化及び低コスト化できる。また、回転支持部材３３の軸方向中間部における横断面形状は円形状の他、多角形状としてもよい。また、回転支持部材３３は、軸方向に一様の横断面形状を有していても、横断面形状が軸方向に変化する形状であってもよい。
本例においては、中実棒状の回転支持部材３３の軸方向両端部を、対向配置された支持板２１、２１によって直接支持するので、ロープＲの張設方向における強度を確保できる。
回転支持部材３３に形成したネジ穴３５は、ロープＲに対する初期張力の設定に必要な長さを確保できれば、必ずしも回転支持部材３３を貫通してなくてもよい。 <Effect>
As described above, according to the present embodiment, since the rope R is swingably supported by the rotation support member 33 and the rope support member 41 around the axis B of the rotation support member 33, the building frame with respect to the frame materials 101 and 101 The stretching direction of the rope R can be freely adjusted according to the angle of the diagonal line A of 100.
In the present embodiment, the rotary support member 33 freely supports the rope support member 41, so that the portion functions as a tension adjusting means for the rope R. Since the turnbuckle (tension adjusting means) can be omitted as compared with the conventional configuration, the number of parts can be reduced.
Only one rope support member 41 as the tension adjusting means is required in the rope seismic resistance unit 1. Therefore, one support unit 10A supports one end of the rope R in the longitudinal direction by the rope support member 41, and the other support unit 10B supports the other end of the rope R in the longitudinal direction by the rotation support member 33. can. In this case, the position of the screw hole 35 of the rotary support member 33 of the support unit 10A and the position of the screw hole 35 of the other support unit 10B are arranged so as not to overlap in the width direction of the frame member 101, so that the support unit 10B is arranged. The screw hole 35 and the other end of the rope R in the longitudinal direction do not interfere with each other, and the situation where the rope is damaged by the screw hole 35 can be avoided.
Since the screw hole 35 of the rotation support member 33 is formed at a position deviated from the axial center of the rotation support member 33 to one side, when a plurality of (for example, two) ropes R are arranged on the building frame 100. Even if there is, the position of the rope R can be shifted in the width direction of the frame member 101, and damage to the rope due to interference between the ropes can be prevented. As an example of use in which two ropes R are arranged in the building frame 100, two ropes R are fixed to one set of rope seismic units 1 arranged in the building frame 100, or the building frame. It is conceivable that the rope R is fixed to each of the two sets of rope seismic units 1 arranged in the 100, and the rope R is arranged in an X shape in the building frame 100. A plurality of screw holes 35 may be formed in the axial direction of the rotation support member 33 so that three or more ropes R can be arranged in the width direction of the frame member 101.
In the above embodiment, the rotation support member 33 has a solid rod shape, but may have a hollow cylindrical shape. In this case, the rotation support member 33 can be reduced in weight and cost. Further, the cross-sectional shape of the rotation support member 33 in the intermediate portion in the axial direction may be a polygonal shape as well as a circular shape. Further, the rotation support member 33 may have a uniform cross-sectional shape in the axial direction, or may have a shape in which the cross-sectional shape changes in the axial direction.
In this example, since both ends of the solid rod-shaped rotary support member 33 in the axial direction are directly supported by the support plates 21 and 21 arranged opposite to each other, the strength of the rope R in the stretching direction can be ensured.
The screw hole 35 formed in the rotation support member 33 does not necessarily have to penetrate the rotation support member 33 as long as the length required for setting the initial tension with respect to the rope R can be secured.

〔第二の実施形態〕
図６は、本発明の第二の実施形態に係るロープ耐震ユニットの支持ユニットを示す一部断面図である。本実施形態に係る支持ユニットにおいて回転支持部材は、ネジ山を有さない貫通した孔を備え、該孔によってロープ支持部材を出没自在に支持する点に特徴がある。以下、第一の実施形態と同一の部材には同一の符号を付してその説明を省略すると共に、主として第一の実施形態との相違点について説明する。
回転支持部材３３の軸方向の一端寄り（軸方向の中央部から一端に偏った位置）には、軸線Ｂに対して直交する方向に挿通孔５１が貫通形成されている。挿通孔５１には、ロープ支持部材４１の雄ネジ部４５が挿通され、挿通孔５１から突出する雄ネジ部４５の先端部４５ａには、ナットＮａが締結される。 [Second embodiment]
FIG. 6 is a partial cross-sectional view showing a support unit of the rope seismic resistance unit according to the second embodiment of the present invention. In the support unit according to the present embodiment, the rotary support member is characterized in that it is provided with a through hole having no thread and the rope support member is freely supported by the hole. Hereinafter, the same members as those in the first embodiment are designated by the same reference numerals, the description thereof will be omitted, and the differences from the first embodiment will be mainly described.
An insertion hole 51 is formed through the rotation support member 33 in a direction orthogonal to the axis B at one end in the axial direction (a position biased from the central portion in the axial direction to one end). The male screw portion 45 of the rope support member 41 is inserted into the insertion hole 51, and the nut Na is fastened to the tip portion 45a of the male screw portion 45 protruding from the insertion hole 51.

本実施形態に係るロープ耐震ユニットの使用方法は以下の通りである。
図１に示すように、２つの支持ユニット１０Ａ、１０Ｂを対角線Ａ方向に位置する２つの仕口部１０３ａ、１０３ｃに夫々固定した後、ロープＲの長手方向の両端部を支持ユニット１０Ａ、１０Ｂに固定する。即ち、ロープＲの長手方向の一方の端部を、図５（ｂ）に示すように、支持ユニット１０Ｂの回転支持部材３３に対してもやい結び等を利用して結びつけて固定する。ロープＲの長手方向の他方の端部は、図６に示すように、もやい結び等を利用して支持ユニット１０Ａのロープ支持部材４１のロープ固定部４３に結びつけて固定する。
図６に示すように、ロープ支持部材４１の雄ネジ部４５を回転支持部材３３の挿通孔５１内に挿通し、挿通孔５１から突出した雄ネジ部４５の先端部４５ａにナットＮａを螺着して、ロープＲに張力が加わった場合にロープ支持部材４１が回転支持部材３３から脱落しないようにする。また、雄ネジ部４５に対するナットＮａの位置を調整して、回転支持部材３３に対する雄ネジ部４５の軸線Ｆ方向における位置を、ロープＲに必要な初期張力を与えることができる位置に設定する。 The method of using the rope seismic unit according to this embodiment is as follows.
As shown in FIG. 1, after fixing the two support units 10A and 10B to the two joints 103a and 103c located in the diagonal A direction, both ends of the rope R in the longitudinal direction are attached to the support units 10A and 10B. Fix it. That is, as shown in FIG. 5B, one end of the rope R in the longitudinal direction is tied and fixed to the rotary support member 33 of the support unit 10B by using a bowline or the like. As shown in FIG. 6, the other end of the rope R in the longitudinal direction is tied to and fixed to the rope fixing portion 43 of the rope support member 41 of the support unit 10A by using a bowline or the like.
As shown in FIG. 6, the male screw portion 45 of the rope support member 41 is inserted into the insertion hole 51 of the rotary support member 33, and the nut Na is screwed into the tip portion 45a of the male screw portion 45 protruding from the insertion hole 51. Then, when tension is applied to the rope R, the rope support member 41 is prevented from falling off from the rotation support member 33. Further, the position of the nut Na with respect to the male screw portion 45 is adjusted to set the position of the male screw portion 45 with respect to the rotation support member 33 in the axis F direction to a position where the required initial tension can be applied to the rope R.

以上のように本実施形態によれば、ロープＲに対して初期張力を与えるときにロープ支持部材４１が回転しないので、ロープＲが捻れないという効果がある。なお、図６に示すように、雄ネジ部４５のロープ固定部４３側（基端部４５ｂ）に任意でナットＮｂを螺着してもよい。ナットＮｂを螺着することにより、回転支持部材３３に対してロープ支持部材４１を雄ネジ部４５の軸方向に固定でき、地震の発生に伴ってロープＲが緊張と弛緩を繰り返すような場合にも、ロープ支持部材４１が回転支持部材３３に対してがたつくことを防止できる。 As described above, according to the present embodiment, since the rope support member 41 does not rotate when the initial tension is applied to the rope R, there is an effect that the rope R does not twist. As shown in FIG. 6, the nut Nb may be optionally screwed to the rope fixing portion 43 side (base end portion 45b) of the male screw portion 45. By screwing the nut Nb, the rope support member 41 can be fixed to the rotary support member 33 in the axial direction of the male screw portion 45, and the rope R repeatedly tensions and relaxes due to the occurrence of an earthquake. Also, it is possible to prevent the rope support member 41 from rattling with respect to the rotation support member 33.

〔第三の実施形態〕
図７は、本発明の第三の実施形態に係るロープ耐震ユニットの支持ユニットを示す斜視図である。本実施形態に係る支持ユニットにおいては、第一の実施形態における取付板１３と支持板２１とを同一平面状に配置した点に特徴がある。以下、第一の実施形態と同一の部材には同一の符号を付してその説明を適宜省略する。
支持ユニット１０（１０Ａ）において、仕口部１０３に固定されるベース部材１１は、対向配置される２つのベースプレート６１、６１を備える。ベースプレート６１、６１は、直交（又は交差）する２本の枠材１０１ａ、１０１ｂの内側に面した側面（内側面１０７）とは異なる側面（外側面１０８）に固定される。
ベースプレート６１は、概略扇形状の支持板部６３と、支持板部６３の周方向（図中矢印Ｄ方向）両端部から延在すると共に枠材１０１ａ、１０１ｂの外側面１０８、１０８に夫々固定される取付片６５、６５とを備える。取付片６５、６５には取付孔（不図示）が貫通形成されており、ベースプレート６１はネジや釘等の留め具１９を利用して、枠材１０１ａ、１０１ｂの外側面１０８、１０８に両枠材１０１ａ、１０１ｂ間に跨がって固定される。
本例においては、取付片６５、６５が支持板部６３と同一平面上に位置するため、留め具１９を建築枠体１００の対角線と直交する方向に打ち込むことができる。従って、ロープＲが負担する張力は、留め具１９に対してそのせん断方向に働くため、建築枠体１００に対するベース部材１１の固定力が向上する。 [Third Embodiment]
FIG. 7 is a perspective view showing a support unit of the rope seismic unit according to the third embodiment of the present invention. The support unit according to the present embodiment is characterized in that the mounting plate 13 and the support plate 21 in the first embodiment are arranged in the same plane. Hereinafter, the same members as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted as appropriate.
In the support unit 10 (10A), the base member 11 fixed to the joint 103 includes two base plates 61, 61 which are arranged to face each other. The base plates 61 and 61 are fixed to a side surface (outer surface 108) different from the inner side surface (inner surface 107) of the two orthogonal (or intersecting) frame members 101a and 101b.
The base plate 61 extends from both ends of the support plate portion 63 having a substantially fan shape and the circumferential direction (arrow D direction in the figure) of the support plate portion 63, and is fixed to the outer surfaces 108 and 108 of the frame members 101a and 101b, respectively. The mounting pieces 65 and 65 are provided. Mounting holes (not shown) are formed through the mounting pieces 65 and 65, and the base plate 61 uses fasteners 19 such as screws and nails to form both frames on the outer surfaces 108 and 108 of the frame materials 101a and 101b. It is fixed straddling between the materials 101a and 101b.
In this example, since the mounting pieces 65 and 65 are located on the same plane as the support plate portion 63, the fastener 19 can be driven in a direction orthogonal to the diagonal line of the building frame 100. Therefore, since the tension borne by the rope R acts on the fastener 19 in the shearing direction, the fixing force of the base member 11 to the building frame 100 is improved.

Interference with screw holes or insertion holes may damage the rope. According to this aspect, the positions of the screw holes or insertion holes of the rotary support member can be shifted from the support units 10A and 10B in the width direction of the frame member 101 constituting the building frame, and the rope can be arranged. Can prevent damage.
Further, when a plurality of (for example, two) ropes R are arranged on the building frame 100, the attachment position of the ropes R can be shifted in the width direction of the frame material 101, and the ropes may be damaged due to interference between the ropes. Can be prevented.
