【0008】[0008]
(請求項1によれば)地震の横揺れにより、当接固定部材が床面と共に水平方 向へ揺れると、第2球面軸受部の首振りにより当接固定部材が床面と平行な姿勢 に保持されつつ、第1球面軸受部の首振りにより、移動壁固定用支持杆が第1球 面軸受部を中心に揺動する。このため、移動壁本体と床面が、相対的に横揺れ自 在となり、移動壁本体は破損しない。 (According to claim 1) When the abutment fixing member sways in the horizontal direction together with the floor surface due to the lateral movement of the earthquake, the abutment fixing member is placed in a posture parallel to the floor surface due to the swing of the second spherical bearing portion. While being held, the swinging movement of the first spherical bearing portion causes the support rod for fixing the moving wall to swing around the first spherical bearing portion. For this reason, the moving wall body and the floor surface are relatively swaying independently, and the moving wall body is not damaged.
【0009】 (請求項2によれば)通常は、第1球面軸受部が首振不可能な状態にあるので 、移動壁本体を床面に対して固定でき、移動壁本体はぐらつかない。地震が発生 すると、床面の横揺れが第2球面軸受部に伝わり、内連接部と外連接部が相互に 回転する力が作用するので、ねじ部材が内連接部と外連接部との境界面にて剪断 破断して、移動壁固定用支持杆が首振自在となる。このため、移動壁本体と床面 が、相対的に横揺れ自在となり、移動壁本体は破損しない。(According to the second aspect) Normally, since the first spherical bearing portion is in a state in which it cannot swing, the moving wall body can be fixed to the floor surface, and the moving wall body does not wobble. When an earthquake occurs, the rolling motion of the floor surface is transmitted to the second spherical bearing, and the force that rotates the inner and outer joints acts on each other, so that the screw member is the boundary between the inner and outer joints. Shear and fracture at the surface, and the support rod for fixing the moving wall can swing freely. For this reason, the moving wall body and the floor surface can freely roll sideways, and the moving wall body is not damaged.
【0010】 (請求項3によれば)第2球面軸受部の外連接部と内連接部との間に、多数の 小球体があるので、第2球面軸受部に上下方向の大きな圧縮力が作用していても 、確実に首振りできる。従って、地震の際に、当接固定部材と移動壁固定用支持 杆は破損せず、移動壁固定用支持杆が確実に揺動する。(According to claim 3) Since there are many small spheres between the outer connecting portion and the inner connecting portion of the second spherical bearing portion, a large vertical compressive force is exerted on the second spherical bearing portion. Even if it works, you can surely swing. Therefore, in the event of an earthquake, the abutment fixing member and the support rod for fixing the moving wall are not damaged, and the support rod for fixing the moving wall surely swings.

【0037】 取付部材22は、平面視長方形の本体部22aと、その長手方向両端部にねじ着さ れて転動ボール21…を抜け止めする抜止部22b,22bと、から構成されている。 本体部22aは、中央に貫孔27を有する。そして、その貫孔27に、スライド杆部10 の下端部に形成されたねじ部23を上方から挿通して、そのねじ部23に下方からナ ット部材26を螺嵌することにより、本体部22aがスライド杆部10に固着される。The mounting member 22 is composed of a main body portion 22a having a rectangular shape in plan view, and retaining portions 22b, 22b which are screwed to both ends in the longitudinal direction thereof to prevent the rolling balls 21 ... from coming off. The main body portion 22a has a through hole 27 in the center. Then, the threaded portion 23 formed at the lower end portion of the slide rod portion 10 is inserted into the through hole 27 from above, and the nut member 26 is screwed into the threaded portion 23 from below, whereby the main body portion is formed. 22a is fixed to the slide rod 10.
【0038】 (図2にもどって)移動壁本体3は、吊下部材2が挿入される上方開口状の挿 入孔28を有する。該移動壁本体3の前後両面には、外装板34, 34が、固設されて いる。しかして、移動壁本体3に、重量支持部9の転動ボール21…が下方から転 動自在に当接する受け面29を、形成する。(Returning to FIG. 2) The moving wall body 3 has an insertion hole 28 in the shape of an upper opening into which the suspension member 2 is inserted. Exterior plates 34, 34 are fixedly provided on both front and rear surfaces of the moving wall body 3. Thus, the moving wall body 3 is formed with a receiving surface 29 on which the rolling balls 21 of the weight supporting portion 9 are rotatably abutted from below.
【0039】 即ち、図2と図4に示すように、移動壁本体3の挿入孔28内に、吊下部材2の スライド杆部10を挿通する貫孔30を有する係止部材31を、固設し、その係止部材 31の下面が受け面29とされる。That is, as shown in FIGS. 2 and 4, in the insertion hole 28 of the moving wall body 3, a locking member 31 having a through hole 30 for inserting the slide rod portion 10 of the hanging member 2 is fixed. The lower surface of the locking member 31 serves as the receiving surface 29.
【0040】 また、図4と図7に示すように、重量支持部9は、受け面29に沿って水平左右 方向へ移動可能な左右余裕代U,Uをもって該受け面29に当接する。即ち、転動 ボール21…は、移動壁本体3の受け面29に沿って水平左右方向へ移動可能な左右 余裕代U,Uをもって該受け面29に当接する。Further, as shown in FIGS. 4 and 7, the weight support portion 9 abuts on the receiving surface 29 with left and right allowances U, which are movable horizontally along the receiving surface 29. That is, the rolling balls 21 ... Abut on the receiving surface 29 with a left and right margin allowances U, which can move in the horizontal left-right direction along the receiving surface 29 of the moving wall body 3.
【0041】 具体的には、係止部材31の受け面29は、左右方向に余裕をもって長くされてお り、かつ、係止部材31の貫孔30は、左右方向の長孔とされている(図7参照)。 これにより、吊下部材2は、移動壁本体3に対して、水平左右方向へ所定寸法W だけスライド自在となる。Specifically, the receiving surface 29 of the locking member 31 is elongated in the left-right direction with a margin, and the through hole 30 of the locking member 31 is a long hole in the left-right direction. (See Figure 7). As a result, the hanging member 2 is slidable with respect to the moving wall body 3 in the horizontal left-right direction by a predetermined dimension W 1.
【0042】 また、重量支持部9を、当接状態から分離する下方向へ移動可能な上下余裕代 Vをもってスライド杆部10に、取付ける(図2参照)。具体的には、スライド杆 部10の上部に、下方へ向く段付部32を形成し、かつ、移動壁本体3の当接部材31 の上面近傍位置に、該段付部32に対向するストッパ面33を形成する。Further, the weight support portion 9 is attached to the slide rod portion 10 with a vertical allowance V that can be moved downward to separate it from the contact state (see FIG. 2). Specifically, a stepped portion 32 that faces downward is formed on the upper portion of the slide rod 10, and a stopper that faces the stepped portion 32 is provided at a position near the upper surface of the contact member 31 of the moving wall body 3. Form surface 33.
【0043】 これにより、スライド杆部10(即ち吊下部材2)は、受け面29に重量支持部9 の転動ボール21…が当接した状態における段付部32とストッパ面33との上下寸法 Hだけ、移動壁本体3に対して下方へスライド可能となる。As a result, the slide rod portion 10 (that is, the suspension member 2) moves up and down between the stepped portion 32 and the stopper surface 33 when the rolling balls 21 of the weight support portion 9 are in contact with the receiving surface 29. Only the dimension H can be slid downward with respect to the moving wall body 3.
【0044】 なお、図10に示すように、移動壁本体3は、左右2本の吊下部材2,2にて、 吊下られる。そして、一方の吊下部材2aが、上述のように左右方向へスライド 自在とされ、かつ、下方へ移動可能とされる。As shown in FIG. 10, the moving wall body 3 is suspended by two suspension members 2 and 2 on the left and right. Then, one suspension member 2a is slidable in the left-right direction as described above and is movable downward.
【0045】 また、他方の吊下部材2bは、図8に示すように、移動壁本体3に対して下方 へ移動可能とされるが、左右方向へは移動できないように構成されている。As shown in FIG. 8, the other suspension member 2b is configured to be movable downward with respect to the moving wall body 3, but not movable in the left-right direction.
【0046】 即ち、図9に示すように、スライド杆部10が挿通された当接部材31の貫孔30は 、スライド杆部10の外径よりも僅かに大きな内径を有する円形の孔とされる。か つ、重量支持部9は平面視矩形状の小板片のみから成り、図2〜図7に示した転 動ボール21と小球体25を有していない。なお、その他の構成については、図2と 図3に示したものと同様とされる。That is, as shown in FIG. 9, the through hole 30 of the contact member 31 through which the slide rod 10 is inserted is a circular hole having an inner diameter slightly larger than the outer diameter of the slide rod 10. It On the other hand, the weight supporting portion 9 is composed only of a small plate piece having a rectangular shape in plan view, and does not have the rolling ball 21 and the small spherical body 25 shown in FIGS. Note that the other configurations are similar to those shown in FIGS. 2 and 3.
【0047】 上述のように構成したことにより、通常は、図1に示すように、移動壁固定用 脚部35は、移動壁本体3の下部に鉛直状態に固定保持されている。かつ、図2と 図12に示すように、吊下部材2が鉛直に保持されると共に、重量支持部9が移動 壁本体2の受け面29に当接した当接状態となっている。Due to the above-mentioned configuration, normally, as shown in FIG. 1, the moving wall fixing leg portion 35 is fixed and held in the vertical state at the lower portion of the moving wall body 3. Moreover, as shown in FIGS. 2 and 12, the suspension member 2 is held vertically and the weight support portion 9 is in contact with the receiving surface 29 of the moving wall body 2.
【0048】 しかして、地震が発生して建築構造物が激しく揺れると、水平方向の揺れ(横 揺れ)により、図11に示すように、吊下部材2の上杆部12が、その上方の吊車、 レール、天井等と共に矢印Jで示すように水平方向へ揺れるため、ねじ部材20が 内連接部4と外連接部6との境界面にて破断して、首振継手部7が首振自在とな る。Then, when an earthquake occurs and the building structure shakes violently, the upper rod portion 12 of the hanging member 2 is moved upward by the horizontal shaking (horizontal shaking), as shown in FIG. As it sways in the horizontal direction as indicated by the arrow J with the suspension vehicle, rail, ceiling, etc., the screw member 20 breaks at the boundary surface between the inner connecting portion 4 and the outer connecting portion 6, and the swing joint portion 7 swings. Be free.
【0049】 即ち、首振継手部7に曲げ力が負荷してねじ部材20の先端部に大きな剪断力が 作用するので該ねじ部材20の先端部が破断して、内連接部4の小凹所19内に、ね じ部材20の先端の破片20aが残った状態で、外連接部6に対して内連接部4が回 転する。That is, since a bending force is applied to the swing joint portion 7 and a large shearing force acts on the tip end portion of the screw member 20, the tip end portion of the screw member 20 is broken, and the small concave portion of the inner connecting portion 4 is broken. The inner connecting portion 4 rotates with respect to the outer connecting portion 6 with the fragments 20a at the tip of the screw member 20 remaining inside the place 19.
【0050】 そして、移動壁本体3が、その下部またはその近傍を中心として矢印Kにて示 すように揺動自在となって水平方向の地震エネルギーが吸収される。即ち、吊下 部材2が首振継手部7にて関節状となって首振りするため、吊下部材2に生ずる 内部応力が小さくなり、該吊下部材2が切断するのを防止できる。従って、移動 壁本体3を天井に吊り下げた状態に保持することができ、該移動壁本体3は倒れ ない。Then, the moving wall main body 3 is made swingable around the lower portion or the vicinity thereof as shown by an arrow K, and seismic energy in the horizontal direction is absorbed. That is, since the suspension member 2 forms a joint in the swing joint portion 7 and swings, the internal stress generated in the suspension member 2 is reduced, and the suspension member 2 can be prevented from being cut. Therefore, the moving wall body 3 can be held in a suspended state on the ceiling, and the moving wall body 3 does not fall.
【0051】 また、水平方向の揺れにより、建築構造物を成す鉄筋等に、上下方向の撓み( 以下構造2次撓みという場合がある。)と、左右方向の撓みが発生する。さらに 、地震の上下方向の揺れ(突き上げと突き下げ)により、建築構造物を成す鉄筋 等に、上下方向の撓み(以下地震応力撓みという場合がある。)が発生する。In addition, due to the horizontal shaking, vertical bending (hereinafter also referred to as structural secondary bending) and horizontal bending occur in the reinforcing bars and the like that form the building structure. In addition, vertical shaking (up and down) of an earthquake causes vertical bending (hereinafter sometimes referred to as seismic stress bending) in the reinforcing bars that form the building structure.
【0052】 この構造2次撓みと地震応力撓みにより、吊下部材2が移動壁本体3に相対的 に突き下げられると、図13と図14に示すように、吊下部材2が移動壁本体3に相 対的に下降して、受け面29に対して重量支持部9が下方へ分離する。When the suspension member 2 is pushed down relative to the moving wall body 3 due to the secondary bending of the structure and the seismic stress deflection, as shown in FIGS. 13 and 14, the suspension member 2 is moved to the moving wall body 3. 3, the weight supporting portion 9 is separated downward with respect to the receiving surface 29.
【0053】 これにより、上下方向の撓みを吸収することができる。即ち、移動壁本体3と 吊下部材2に、上下方向の圧縮力が作用しないので、吊下部材2の切断を防止で きると共に、移動壁本体3の破損を防止できる。かつ、移動壁本体3は倒れない 。With this, it is possible to absorb the bending in the vertical direction. That is, since the vertical compression force does not act on the moving wall body 3 and the hanging member 2, the hanging member 2 can be prevented from being cut and the moving wall body 3 can be prevented from being damaged. Moreover, the moving wall body 3 cannot fall.
【0054】 なお、吊下部材2は、図12の通常状態から、図14に示すように、吊下部材2の 段付部32が移動壁本体3のストッパ面33に当接するまでの上下寸法Hだけ、移動 壁本体3に相対的に下降できる。従って、この上下寸法Hを、構造2次撓みの寸 法と地震応力撓みの寸法との和と同一乃至それよりも大きく設定しておけば、上 下方向の撓みをすべて吸収することが可能である。The suspension member 2 has a vertical dimension from the normal state of FIG. 12 until the stepped portion 32 of the suspension member 2 contacts the stopper surface 33 of the moving wall body 3 as shown in FIG. Only H can be lowered relative to the moving wall body 3. Therefore, if this vertical dimension H is set to be equal to or larger than the sum of the dimension of the structural secondary deflection and the dimension of the seismic stress deflection, it is possible to absorb all the upward and downward deflections. is there.
【0055】 また、水平方向の揺れにより、図15に示すように、移動壁固定用脚部35の当接 固定部材37が、その下方の床と共に矢印Mで示すように水平方向へずれるため、 第1球面軸受部38のねじ部材45が内連接部40と外連接部42との境界面にて破断し て、第1球面軸受部38が首振自在となる。Further, as shown in FIG. 15, the abutment fixing member 37 of the moving wall fixing leg portion 35 shifts in the horizontal direction together with the floor below it as shown by an arrow M due to the horizontal shaking, The screw member 45 of the first spherical bearing portion 38 breaks at the boundary surface between the inner connecting portion 40 and the outer connecting portion 42, and the first spherical bearing portion 38 becomes swingable.
【0056】 即ち、第2球面軸受部39は常時首振自在であため、移動壁固定用支持杆36を介 して、第1球面軸受部38に曲げ力が負荷し、ねじ部材45の先端部に大きな剪断力 が作用する。これにより、ねじ部材45の先端部が破断して、内連接部40の小凹所 44内に、ねじ部材45の先端の破片45aが残った状態で、外連接部42に対して内連 接部40が回転する。That is, since the second spherical bearing portion 39 is always swingable, the bending force is applied to the first spherical bearing portion 38 via the moving wall fixing support rod 36, and the tip end of the screw member 45 is loaded. A large shearing force acts on the part. As a result, the tip portion of the screw member 45 is broken, and the fragment 45a at the tip of the screw member 45 remains in the small recess 44 of the inner connecting portion 40. The part 40 rotates.
【0057】 そして、脚部35が、上端部を中心として揺動自在となる。従って、前記吊下部 材2の制約は受けるが、移動壁本体3と床面50が、相対的に横揺れ自在となる。 かつ、移動壁本体3の破損を防止できる。Then, the leg portion 35 becomes swingable around the upper end portion. Therefore, the moving wall main body 3 and the floor surface 50 can be relatively laterally swung, although the suspension member 2 is restricted. Moreover, damage to the moving wall body 3 can be prevented.
【0058】 また、地震の第1動が床面50の突き上げの動きである場合は、移動壁固定用脚 部35を介して移動壁全体が突き上げられるので、図13と図14に示したように、吊 下部材2に相対的に移動壁本体3が上昇して、その突き上げ力を吸収することが できる。When the first motion of the earthquake is the push-up motion of the floor surface 50, the entire moving wall is pushed up via the moving-wall fixing legs 35, and therefore, as shown in FIGS. 13 and 14. In addition, the moving wall body 3 can be raised relative to the suspension member 2 to absorb the thrust force.
【0059】 従って、吊下部材2と移動壁本体3と脚部35の破損を防止できると共に、移動 壁本体3の転倒を防止できる。Therefore, it is possible to prevent the suspension member 2, the moving wall body 3, and the leg portion 35 from being damaged, and to prevent the moving wall body 3 from falling.
