Description
本発明は、免震建物と非免震建物との躯体間に設けられたクリアランス(間隙部)を覆うエキスパンションジョイント床部材とエキスパンションジョイント内壁面を構成するエキスパンションジョイントに関するものであり、特に、本発明は、地震発生時において上記建物間に設けられたクリアランス部における可動の方向性を重視した床面部材と内壁面部材にて構成されるエキスパンションジョイント部材に関するものである。 The present invention relates to an expansion joint floor member that covers a clearance (gap part) provided between a frame between a base-isolated building and a non-base-isolated building, and an expansion joint that constitutes an expansion joint inner wall surface. Is related to an expansion joint member composed of a floor member and an inner wall member that place importance on the directionality of movement in a clearance portion provided between the buildings when an earthquake occurs.
而して、本発明は、免震建物と非免震建物が形成する躯体間のクリアランス(間隙部)に設置される床面部材と内壁面部材にて構成するエキスパンションジョイントにおいて、エキスパンションジョイント床面部材とエキスパンションジョイント内壁面部材が地震可動時において相互に連動して可動する場合に対応して床面部材と内壁面部材の連動可動を円滑化して、エキスパンションジョイントの床面部材とエキスパンションジョイントの内壁面部材を相互に破損させることなく円滑可動でき、地震時の揺れに対応可能な床面部材と内壁面部材からなるエキスパンションジョイントを提供するものである。 Thus, the present invention relates to an expansion joint comprising a floor member and an inner wall member installed in a clearance (gap) between the frames formed by the base-isolated building and the non-base-isolated building. When the member and the inner wall member of the expansion joint move in conjunction with each other during an earthquake, smooth movement of the floor member and the inner wall member is facilitated. It is an object of the present invention to provide an expansion joint composed of a floor member and an inner wall member that can move smoothly without damaging the wall members and can cope with shaking during an earthquake.
エキスパンションジョイントにおける可動の方向性については、地盤に対して水平方向の動きでクリアランスの拡大収縮方向の動きを示す水平X方向変位と、地盤に対して水平方向の動きでクリアランスに対してスライド方向の動きを示す水平Y方向変位、及び地盤に対して垂直方向の動きを示す垂直Z方向変位がある。
従って、免震建物のエキスパンションジョイントにおいては、特に、建物が地震可動時に前記水平X方向変位と水平Y方向変位を生じることに対する地震対応策が最重要事項であり、垂直Z方向変位に関しては、対向して建てられた建築物が不同沈下などの理由で地盤に対して垂直方向の動きをすることに起因するものであることから、床面部材と内壁面部材を構成するエキスパンションジョイントに関しては、水平X方向変位と水平Y方向変位に対して床面部材と内壁面部材とが円滑に連動し、エキスパンションジョイント床面部材とエキスパンションジョイント内壁面部材が互に緩衝して破損することなく連動して可動可能なエキスパンションジョイントの開発が必要になってきた。
With regard to the directionality of movement at the expansion joint, the horizontal X direction displacement that indicates the movement of the clearance in the horizontal direction with respect to the ground and the sliding direction with respect to the clearance with the horizontal movement with respect to the ground. There is a horizontal Y-direction displacement indicating movement, and a vertical Z-direction displacement indicating vertical movement with respect to the ground.
Therefore, in the expansion joint of a base-isolated building, the earthquake countermeasures against the occurrence of the horizontal X-direction displacement and the horizontal Y-direction displacement when the building is movable is the most important matter. The expansion joints that make up the floor member and the inner wall member are horizontal because the building constructed in this way is caused by the vertical movement with respect to the ground for reasons such as uneven settlement. The floor member and the inner wall surface member are smoothly interlocked with the X-direction displacement and the horizontal Y-direction displacement, and the expansion joint floor member and the expansion joint inner wall surface member can be interlocked and moved without being damaged. Development of possible expansion joints has become necessary.
即ち、免震建物と非免震建物間に形成されるクリアランス(間隙部)は、屋根部や天井部、外壁部や内壁部、そして、人や車の出入り部分に設けられる床部等があり、夫々の間隙部に設置されるエキスパンションジョイントは、設置場所により独自の構造を有して建物間の相互移動に対応するクリアランスを確保すると同時に、該クリアランスを覆い免震建物と非免震建物間に設置されて地震時の相互可動に対応できるエキスパンションジョイントが必要不可欠となる。 In other words, clearances (gap parts) formed between base-isolated buildings and non-base-isolated buildings include roofs and ceilings, outer walls and inner walls, and floors provided at the entrance and exit of people and cars. The expansion joints installed in the respective gaps have a unique structure depending on the installation location and ensure clearance corresponding to mutual movement between buildings, and at the same time, cover the clearance between the seismic isolated building and the non-isolated building Expansion joints that can be installed in the earthquake and can handle mutual movement during an earthquake are indispensable.
斯くして、本発明は、免震建物と非免震建物が形成する躯体間のクリアランス部分に設置される床面部材と内壁面部材にて構成されるエキスパンションジョイントに関するものである。
床面部材と内壁面部材から構成されるエキスパンションジョイントにおいて、最近は免震化の影響で免震建物と非免震建物との躯体間のクリアランス(間隙部)は広がる傾向があり、前記躯体間のクリアランス部分に設置されるエキパンジョイント部材は、躯体間のクリアランス部分をジョイント用目地カバー部材(以下、目地カバー部材と称する)にて覆い、該目地カバー材は地震時における躯体間の大きな変形に対応できることが要求されている。
Thus, the present invention relates to an expansion joint composed of a floor member and an inner wall member installed in a clearance portion between the frames formed by the base-isolated building and the non-base-isolated building.
In expansion joints composed of floor members and inner wall members, the clearance (gap) between the seismic isolated building and non-isolated building tends to increase due to the seismic isolation. The expansion joint member installed in the clearance part of the cover covers the clearance part between the enclosures with joint joint cover members (hereinafter referred to as joint cover members). It is required to be able to respond.
また、本発明の床面エキパンジョイント部材、及び内壁面エキパンジョイント部材は、互いに隣接して設けられることから地震可動時において、互いに連動して相互に衝突し、破損させることなく床面部材と内壁面部材が連動して可動するエキスパンションジョイントを提供することが重要であり、通常時に左右の床目地カバー部材からなる床面エキスパンションジョイント面において左右の床面と目地カバー部材とが同一面上に配置されるように設置できること、並びに、地震可動時において床面の目地カバー部材が収縮した場合には、目地カバー部材の先端部が他の目地カバーの下部にスライド移動して挿入されることにより、他の目地カバープレートを上部にせり上げて建物間のクリアランス(間隙部)が最小限までにも収縮した場合においても対応できることが要求される。 In addition, since the floor surface expansion joint member and the inner wall surface expansion joint member of the present invention are provided adjacent to each other, they can collide with each other in the event of earthquake movement and collide with each other without causing damage. It is important to provide an expansion joint in which the wall members move in conjunction with each other. Normally, the left and right floor surfaces and joint cover members are placed on the same surface on the floor expansion joint surface consisting of the left and right floor joint cover members. In addition, when the joint cover member on the floor surface contracts when the earthquake is movable, the tip of the joint cover member slides into the lower part of the other joint cover and is inserted, When the other joint cover plate is raised to the top and the clearance (gap) between the buildings contracts to the minimum Oite also are required to be supported.
而して、従来の床面エキスパンションジョイント部材として、地震可動時における動作方向が、免震建物と非免震建物が形成する躯体のクリアランス部において水平X方向変位(Xスライド方向)への動作のみに単純化したと云う免震エキスパンションジョイント床部材の滑動措置が、特開2009−102974号公報(以下、特許文献1と称する)に記載されている。 Thus, as a conventional floor expansion joint member, the movement direction when the earthquake is movable is only the movement to the horizontal X direction displacement (X slide direction) in the clearance part of the frame formed by the base-isolated building and the non-base-isolated building. Japanese Patent Application Laid-Open No. 2009-102974 (hereinafter referred to as Patent Document 1) describes a sliding measure for a seismic isolation expansion joint floor member, which has been simplified.
特許文献1は、目地部の幅寸法が目地部の約二倍の幅寸法を有することで設置可能とする床目地装置(床面エキスパンションジョイント)であり、床目地部において目地寸法分だけが伸縮して揺れ動きを確実に吸収する床目地装置を提供するものであるとしている。 Patent Document 1 is a floor joint device (floor surface expansion joint) that can be installed by having a width dimension of the joint part approximately twice that of the joint part, and only the joint dimension of the floor joint part can be expanded and contracted. The floor joint device that reliably absorbs the shaking motion is provided.
然しながら、特許文献1のような片側支持による目地カバー部材の固定構造を採用し、目地部の幅寸法の約二倍の幅寸法を確保することで設置可能で目地寸法分だけ伸縮する揺れ動きを吸収する床目地装置では、目地カバー部材の揺れ動きを吸収するクリアランスL方向の動きが非常に小さく実用的な目地装置ではない。従って、特許文献1においては、目地部の幅寸法、即ち、クリアランスLが大きな目地装置を必要とする場合に、他方の目地プレート(17)や一方の目地プレート(20)の下部に伸縮可能な目地プレート支持体(16)を設けて、水平X方向変位に対応しているものの、目地部の厚さが厚くなることや装置が複雑化することからクリアランスに対してスライド方向の動きを同時に加えた水平Y方向変位にも対応する目地装置とするには、連動して可動する内壁用目地装置との組合せ構造をも考慮しなくてならず、この点が大きな欠点となっている。 However, the joint cover member fixing structure with one-side support as in Patent Document 1 is adopted, and by securing a width dimension approximately twice the width dimension of the joint part, it can be installed and absorbs the shaking motion that expands and contracts by the joint dimension. In the floor joint device, the movement in the clearance L direction that absorbs the shaking motion of the joint cover member is very small and is not a practical joint device. Therefore, in Patent Document 1, when a joint device having a large joint portion width dimension, that is, a clearance L is required, the joint plate can be expanded and contracted to the lower portion of the other joint plate (17) or one joint plate (20). Although a joint plate support (16) is provided to cope with horizontal displacement in the horizontal direction, movement in the sliding direction is simultaneously added to the clearance because the joint part becomes thicker and the apparatus becomes complicated. In order to make the joint device compatible with the horizontal Y-direction displacement, it is necessary to consider a combination structure with the joint device for the inner wall that moves in conjunction with the joint device, and this is a major drawback.
また、特許文献1の床目地装置では、目地部(クリアランスL)が狭くなった場合の動作説明図(図21)に記載された一方の目地プレート(20C)や、動作説明図(図26)に記載された一方の目地プレート(20D)等の如く他方の目地プレート(17B)の下部への侵入によりせり上がりが大きく上方に突出される動作をすることがあり、この動作中に水平Y方向変位の動きが加わると前記内壁用目地装置が床目地装置に衝突して互いに破損してしまう欠点があり、特許文献1の発明は、水平X方向変位(Xスライド方向)の可動のみを考え、水平Y方向変位(Yスライド方向)の動作を考慮していない実現性のない床目地用エキスパンションジョイントである。 Moreover, in the floor joint apparatus of patent document 1, one joint plate (20C) described in operation | movement explanatory drawing (FIG. 21) when a joint part (clearance L) becomes narrow, and operation | movement explanatory drawing (FIG. 26). Like the one joint plate (20D) described in 1), the upward movement may be caused to protrude upward due to the penetration of the other joint plate (17B). During this operation, the horizontal Y direction may be projected. When the movement of displacement is applied, the joint device for inner wall collides with the floor joint device and breaks each other. The invention of Patent Document 1 considers only the movement in the horizontal X direction displacement (X slide direction), This is an expansion joint for floor joints that does not take into account the movement in the horizontal Y direction displacement (Y slide direction).
本発明は、地震発生時において建物間に設けられたクリアランス(間隙部)における可動の方向性を重視した床面と内壁面を構成するエキスパンションジョイントに関するものである。
そして、本発明は、免震建物と非免震建物が形成する躯体間のクリアランスに設置される床面部材と内壁面部材とで構成するエキスパンションジョイントにおいて、エキスパンションジョイント床面部材とエキスパンションジョイント内壁面部材が地震可動時において相互に連動して可動する場合に対応し床面部材と内壁面部材との相互可動を円滑化して、エキスパンションジョイントの床面部材とエキスパンションジョイントの内壁面部材が互に衝突して破損することなく円滑可動でき、地震時の揺れにおける水平X方向変位(Xスライド方向)と水平Y方向変位(Yスライド方向)にも対応可能な床面と内壁面からなるエキスパンションジョイントを提供するものである。

The movement shown in the figure, the movement in the Y slide direction corresponding to the displacement in the horizontal Y direction, and the movement shown by the arrow 38 in the Y slide direction are made possible.
図3は、エキスパンションジョイント床面部材10とエキスパンションジョイント内壁面部材12の関係を示すもので、その動作は、前記水平X方向変位に対応する動きを示すXスライド方向の矢印37と水平Y方向変位に対応する動きを示すYスライド方向の矢印38の可動動作を行うためにエキスパンションジョイント内壁面部材12のスライド可動内壁14の下部には、スライド用隙間部17が設けられており、この構成を採用することにより、エキスパンションジョイント床面部材10とエキスパンションジョイント内壁面部材12の可動は、互いに部材同士が緩衝することなく可動可能となり、その構成は、非常に狭いスライド用間隙部17の間隙を有するのみの構成となることから、意匠的にシンプルで大変きれいな納まりを提供できる他、エキスパンションジョイント床面部材10とエキスパンションジョイント内壁面部材12が地震発生時に円滑な動作をするエキスパンションジョイントを提供することができる。 FIG. 3 shows the relationship between the expansion joint floor member 10 and the expansion joint inner wall member 12, and the operation thereof is the X slide direction arrow 37 indicating the movement corresponding to the horizontal X direction displacement and the horizontal Y direction displacement. In order to perform the movable operation of the arrow 38 in the Y-sliding direction indicating the movement corresponding to the above, a sliding gap portion 17 is provided at the lower portion of the sliding movable inner wall 14 of the expansion joint inner wall surface member 12, and this configuration is adopted. As a result, the expansion joint floor member 10 and the expansion joint inner wall member 12 can be moved without mutual buffering, and the configuration has only a very narrow gap for the slide gap 17. The design is simple and very beautiful in design. Possible addition, it is possible to expansion joints floor member 10 and the expansion joints in the wall member 12 to provide a expansion joint for a smooth operation in the event of an earthquake.
斯くして、図1乃至図3は、クリアランスC1が通常時の場合における第一の目地カバー部材6と第二の目地カバー部材7の設置の状況を説明してきたが、クリアランスC1が通常時の場合において、水平Y方向変位に対応したYスライド方向の矢印38の横揺れが発生した場合にはおいては、建物Aと建物B間には、図4と図5に示すような水平Y方向変位が生じる。 Thus, FIG. 1 to FIG. 3 describe the installation situation of the first joint cover member 6 and the second joint cover member 7 when the clearance C1 is normal, but the clearance C1 is normal. In the case where the roll of the arrow 38 in the Y slide direction corresponding to the horizontal Y direction displacement occurs, the horizontal Y direction displacement as shown in FIG. 4 and FIG. Occurs.
図4は、建物Bが建物Aに対して矢印41方向に揺動した場合を示し(建物Bが奥行方向に水平方向変位)、この場合には、第二の目地カバー部材7が建物Bの摺動溝36に沿ってスライド移動することにより、第二の目地カバー部材7は第一の目地カバー部材6と同一位置になり、エキスパンションジョイント床面部材10の動作を円滑に行える。また、図5においては、建物Bが矢印42方向に移動した場合を示し(建物Bが手前方向に水平方向変位)、この場合には、建物Bに支持されているスライド可動内壁14が建物Bと共に矢印42方向に移動するので、エキスパンションジョイント床面部材10とエキスパンションジョイント内壁面部材12は互いに衝突することなく水平Y方向変位、即ち、Yスライド方向の矢印38の動きに対応することができる。 FIG. 4 shows the case where the building B swings in the direction of the arrow 41 with respect to the building A (the building B is displaced in the horizontal direction in the depth direction). In this case, the second joint cover member 7 is the building B By sliding along the sliding groove 36, the second joint cover member 7 is located at the same position as the first joint cover member 6, and the operation of the expansion joint floor member 10 can be performed smoothly. FIG. 5 shows a case where the building B moves in the direction of the arrow 42 (the building B is displaced horizontally in the front direction). In this case, the slide movable inner wall 14 supported by the building B is the building B. At the same time, the expansion joint floor member 10 and the expansion joint inner wall member 12 can correspond to the displacement in the horizontal Y direction, that is, the movement of the arrow 38 in the Y slide direction without colliding with each other.
次に、図6乃至図9において、本発明の水平X方向変位と水平Y方向変位の動作説明をする。図6乃至図9において図1乃至図5と同一符号は同一構成要件を示しており、図6乃至図9にて説明される動作は、地震時において建物Aと建物B間のクリアランスC2が最小限まで縮小した場合を説明している。 Next, in FIG. 6 to FIG. 9, the operation of the horizontal X direction displacement and the horizontal Y direction displacement of the present invention will be described. 6 to 9, the same reference numerals as those in FIGS. 1 to 5 denote the same components, and the operations described in FIGS. 6 to 9 are such that the clearance C2 between the building A and the building B is minimized during an earthquake. The case where it is reduced to the limit is explained.

It is explanatory drawing which shows the case where it can move to.
図6において、建物Aの躯体1と建物Bの躯体2の間にはクリアランス(間隙部)C2が設けられており、このクリアランスC2は地震時において建物Aと建物B間のクリアランスが最小限に縮小した場合を示している。そして、建物Aと建物Bとの躯体1と躯体2間の上面には夫々形状の異なる建物A側の凹部形状面3と建物B側の凹部形状面4が設けられており、該建物A側の凹部形状面3上には、滑性の良い金属材料からなるベース基板5が載設されており、更に、建物A側に設けられたベース基板5上には、比較的幅の狭い目地カバー幅W1を有し、前記クリアランスC1を覆わない形態で第一の目地カバー部材6が設置されており、前記建物B側の凹部形状面4と建物A側の凹部形状面3上のベース基板5間には幅広の目地カバー幅W2を有する第二の目地カバー部材7が載架されているエキスパンション床面部材10を形成している、 In FIG. 6, a clearance (gap) C2 is provided between the housing 1 of the building A and the housing 2 of the building B, and this clearance C2 minimizes the clearance between the building A and the building B during an earthquake. The case where it reduced is shown. And the recessed part shape surface 3 by the side of the building A and the recessed part shape surface 4 by the side of the building B which are different shapes are provided in the upper surface between the housing 1 and the housing 2 of the building A and the building B, respectively. A base substrate 5 made of a metal material having a good slidability is placed on the recess-shaped surface 3 of the first substrate, and a relatively narrow joint cover is provided on the base substrate 5 provided on the building A side. The first joint cover member 6 has a width W1 and does not cover the clearance C1, and the base substrate 5 on the concave shape surface 4 on the building B side and the concave shape surface 3 on the building A side. An expansion floor member 10 is formed on which a second joint cover member 7 having a wide joint cover width W2 is mounted.
また、図6において、11は建物A側に設けられた固定内壁で、建物Aと地震時に一緒に可動するもので、該固定内壁11はエキスパンションジョイント内壁面部材12の固定側内壁面を構成しており、また、固定内壁11は前記建物Aのエキスパンションジョイント床面部材10を形成する第一の目地カバー部材6の目地カバー幅W1より大き目でクリアランスC1側に突出しているが、クリアランスC1を跨ぐことはない壁巾を有する固定内壁11で、該固定内壁11は、建物A側の凹部形状面3より立ち上げて形成されている。 In FIG. 6, reference numeral 11 denotes a fixed inner wall provided on the building A side, which moves together with the building A during an earthquake, and the fixed inner wall 11 constitutes the fixed-side inner wall surface of the expansion joint inner wall member 12. The fixed inner wall 11 is larger than the joint cover width W1 of the first joint cover member 6 forming the expansion joint floor member 10 of the building A and protrudes toward the clearance C1, but straddles the clearance C1. The fixed inner wall 11 has a wall width that does not occur. The fixed inner wall 11 is formed so as to rise from the recessed shape surface 3 on the building A side.
而して、図6においては、クリアランスC2が通常時のクリアランスC1に対して地震にて非常に縮小されている形態を示し、この縮小動作の過程で、前記第一の目地カバー部材6は第二の目地カバー部材7の移動圧縮を受ける。そして、目地板18及び目地板31の下部構造は、図2(A)、(B)、(C)の如く構成されていることにより第一の目地カバー部材6は、上部にせり上げられ、第二の目地カバー部材7は第一の目地カバー部材6の下部に重なりあう動作をし、クリアランスC2の収縮に対応しているおり、図6は、この状態を側面図にて示している。 Thus, FIG. 6 shows a form in which the clearance C2 is greatly reduced by the earthquake relative to the normal clearance C1, and in the process of the reduction operation, the first joint cover member 6 The second joint cover member 7 is subjected to moving compression. And the lower structure of the joint board 18 and the joint board 31 is comprised like FIG. 2 (A), (B), (C), The 1st joint cover member 6 is raised to upper part, The second joint cover member 7 operates to overlap the lower portion of the first joint cover member 6 and corresponds to the contraction of the clearance C2, and FIG. 6 shows this state in a side view.
図7において、8は建物A側の床面、18は目地板、6は第一の目地カバー部材、31は目地板、7は第二の目地カバー部材、33は目地板、9は建物B側の床面を夫々示しており、図1にて説明した固定内壁11とスライド可動内壁14の当接部は当接目地材15として示されており、水平X方向変位を受けてXスライド方向の矢印37の動きでクリアランスC2は、最小までに縮小された状態を示している。 In FIG. 7, 8 is a floor surface on the building A side, 18 is a joint plate, 6 is a first joint cover member, 31 is a joint plate, 7 is a second joint cover member, 33 is a joint plate, and 9 is a building B. The abutting portions of the fixed inner wall 11 and the slide movable inner wall 14 described with reference to FIG. 1 are shown as a contact joint material 15, and are subjected to a horizontal X-direction displacement and receive an X-slide direction. The movement of the arrow 37 indicates that the clearance C2 has been reduced to the minimum.
また、図7における37は水平X方向変位に対応する動きを示すXスライド方向の矢印、38は水平Y方向変位に対応する動きを示すYスライド方向の矢印、13は建物Bの躯体上に施工された通路用内壁で、該通路用内壁13にはスライド移動可能なスライド可動内壁14と該スライド可動内壁14に対向して設けられた当接用目地材15を介して固定内壁11が配置されており、8は建物A側の床面、18は目地板、6は第一の目地カバー部材、31は目地板、7は第二の目地カバー部材、33は目地板、36は摺動溝、9は建物B側の床面を夫々示している。而して、クリアランスC2が最小までに縮小した場合にあっても、前記第二の目地カバー部材7はスライド可動内壁14を図面手前側にスライド可能な目地幅Mを有しており、前記スライド可動内壁14の下部には、スライド用隙間部17が設けられていることがら、エキスパンションジョイントが水平Y方向変位を受けてYスライド方向の矢印38の動きをした場合においても、前記スライド可動内壁14はYスライド方向矢印38の動きが可能であり、エキスパンションジョイント床面部材10とエキスパンションジョイント内壁面部材12との納まりは、互いに衝突して損傷することがなく非常に狭いスライド用間隙部17の間隙を有するのみの構成となることから、意匠的にシンプルで大変きれいな納まりを提供することができる。 7, 37 is an arrow in the X slide direction indicating movement corresponding to the horizontal X direction displacement, 38 is an arrow in Y slide direction indicating the movement corresponding to the horizontal Y direction displacement, and 13 is constructed on the building B building. The fixed inner wall 11 is arranged on the inner wall 13 for the passage by way of a slide movable inner wall 14 that can slide and a contact joint material 15 provided opposite to the slide movable inner wall 14. 8 is a floor surface of the building A side, 18 is a joint plate, 6 is a first joint cover member, 31 is a joint plate, 7 is a second joint cover member, 33 is a joint plate, and 36 is a sliding groove. , 9 respectively indicate the floor surface on the building B side. Thus, even when the clearance C2 is reduced to the minimum, the second joint cover member 7 has a joint width M with which the slide movable inner wall 14 can slide to the front side of the drawing, and the slide Since the slide gap 17 is provided at the lower part of the movable inner wall 14, the slide movable inner wall 14 can be used even when the expansion joint receives a displacement in the horizontal Y direction and moves in the direction of the arrow 38 in the Y slide direction. The Y-slide direction arrow 38 can be moved, and the expansion joint floor member 10 and the expansion joint inner wall member 12 can be accommodated in the gap between the very narrow slide gaps 17 without colliding with each other and being damaged. Therefore, the design is simple and very beautiful.
而して、図6及び図7において、クリアランスC2が地震の揺れにより最小までに縮小した場合における第一の目地カバー部材6と第二の目地カバー部材7の設置状況を説明してきたが、クリアランスC2の状況において、水平Y方向変位に対応したYスライド方向の矢印38の横揺れが発生した場合にはおいては、建物Aと建物B間には、図8と図9に示すような水平Y方向変位が生じる。 Thus, in FIGS. 6 and 7, the installation situation of the first joint cover member 6 and the second joint cover member 7 when the clearance C2 is reduced to the minimum due to the shaking of the earthquake has been described. In the situation of C2, when the roll of the arrow 38 in the Y slide direction corresponding to the displacement in the horizontal Y direction occurs, the horizontal Y as shown in FIG. 8 and FIG. Directional displacement occurs.
図8と図9は第一の目地カバー部材6の下方に第二の目地カバー部材7の先端部が重なり合って、第一の目地カバー部材6が上部にせり上がった上がった状態を示し、図8は、建物Bが建物Aに対して矢印41方向に揺動し建物Bが奥行方向に水平方向変位しており、この場合には、第二の目地カバー部材7が建物Bの摺動溝34に沿ってスライド可動することにより、第二の目地カバー部材7は第一の目地カバー部材と同一位置となり、建物Bの躯体上に施工された通路用内壁11とスライド可動内壁14間にずれが生じるがエキスパンションジョイント床面部材10を円滑に動作できる。また、図9においては、建物Bが矢印42方向に移動した場合を示し(建物Bが手前方向に水平方向変位)、この場合には、建物Bに支持されているスライド可動内壁14が建物Bと共にY方向の矢印42方向に移動するのでエキスパンションジョイント床面部材10とエキスパンションジョイント内壁面部材12は互いに衝突することなく水平Y方向変位、即ち、Yスライド方向の矢印38方向の動きに対応することができる。 8 and 9 show the state where the tip of the second joint cover member 7 overlaps the lower side of the first joint cover member 6 and the first joint cover member 6 rises upward. 8, the building B swings in the direction of the arrow 41 with respect to the building A, and the building B is horizontally displaced in the depth direction. In this case, the second joint cover member 7 is a sliding groove of the building B. 34, the second joint cover member 7 is located at the same position as the first joint cover member, and is displaced between the passage inner wall 11 and the slide movable inner wall 14 constructed on the frame of the building B. However, the expansion joint floor member 10 can be operated smoothly. 9 shows a case where the building B moves in the direction of the arrow 42 (the building B is displaced in the horizontal direction in the front direction). In this case, the slide movable inner wall 14 supported by the building B is the building B. The expansion joint floor member 10 and the expansion joint inner wall member 12 correspond to the displacement in the horizontal Y direction, that is, the movement in the arrow 38 direction in the Y slide direction without colliding with each other. Can do.

The enlarged case is shown. And the recessed part shape surface 3 by the side of the building A and the recessed part shape surface 4 by the side of the building B which are different shapes are provided in the upper surface between the housing 1 and the housing 2 of the building A and the building B, respectively. A base substrate 5 made of a metal material having a good slidability is placed on the recess-shaped surface 3 of the first substrate, and a relatively narrow joint cover is provided on the base substrate 5 provided on the building A side.

A second joint cover member 7 having a wide joint cover width W2 is mounted between the first joint cover member 6 and the base substrate 5 on the substantially same surface from the floor surface 8 on the building A side. The second joint cover member 7 covering the clearance C1 is connected to the floor surface 9 on the building B side. Forming a expansion joint floor member 10 which is,
また、図10において、11は建物A側に設けられた固定内壁で、建物Aと地震時に一緒に可動するもので、該固定内壁11は通路用内壁39に接続されており、前記建物Aのエキスパンションジョイント床面部材10を形成する第一の目地カバー部材6の目地カバー幅W1より大き目でクリアランスC3側に突出しているが、クリアランスC3を跨ぐことはない壁巾を有する固定内壁11で、該固定内壁11は、建物A側の凹部形状面3より立ち上げて形成されている。
尚、前記固定内壁11の先端部には当接用目地材15が設けられており、該固定内壁11の当接用目地材15とスライド可動内壁14の角部間には引っ張りスプリング40a、40b、40c・・・が装架されており、該引っ張りスプリング40a、40b、40c・・・は地震発生時の固定内壁11とスライド可動内壁14の動きを揺れの終息時に元に戻す働きをするものである。
In FIG. 10, reference numeral 11 denotes a fixed inner wall provided on the building A side, which moves together with the building A during an earthquake. The fixed inner wall 11 is connected to a passage inner wall 39, and A fixed inner wall 11 having a wall width that is larger than the joint cover width W1 of the first joint cover member 6 forming the expansion joint floor member 10 and protrudes toward the clearance C3 but does not straddle the clearance C3. The fixed inner wall 11 is formed to rise from the concave shape surface 3 on the building A side.
A contact joint material 15 is provided at the tip of the fixed inner wall 11, and tension springs 40 a and 40 b are provided between the contact joint material 15 of the fixed inner wall 11 and the corners of the slide movable inner wall 14. , 40c... And the tension springs 40a, 40b, 40c... Return the movement of the fixed inner wall 11 and the slide movable inner wall 14 at the time of the earthquake to the original state at the end of the shaking. It is.
而して、図10においては、クリアランスC3が通常時のクリアランスC1に対して地震にて非常に拡大されているので、この拡大動作の過程で、前記第二の目地カバー部材7は第一の目地カバー部材6をベース基板5上に降ろし、矢印43に示すように建物B側に大きく移動する。図10はこの時の状態を示し、第二の目地カバー部材7はベース基板5と建物B側の凹部形状面4間に装架されクリアランスC3を形成している。 Thus, in FIG. 10, since the clearance C3 is greatly expanded due to the earthquake with respect to the normal clearance C1, in the course of this expansion operation, the second joint cover member 7 is The joint cover member 6 is lowered onto the base substrate 5 and moved largely to the building B side as indicated by an arrow 43. FIG. 10 shows the state at this time, and the second joint cover member 7 is mounted between the base substrate 5 and the recessed surface 4 on the building B side to form a clearance C3.
図11は、図10の様態を斜視図で示しており、37は水平X方向変位に対応する動きを示すXスライド方向の矢印、38は水平Y方向変位に対応する動きを示すYスライド方向の矢印を示し、エキスパンションジョイント内壁面部材12において、13は建物Bの躯体上に施工された通路用内壁で、該通路用内壁13にはスライド可能なスライド可動内壁11が設けられており、該スライド可動内壁14の先端部には対向して設けられた当接用目地材15を介して固定内壁15が設置されている。また、エキスパンションジョイント床面部材10において、8は建物A側の床面、18は目地板、6は第一の目地カバー部材、31は目地板、5はベース基板、7は第二の目地カバー部材、33は目地板、36は摺動溝、9は建物B側の床面を夫々示している。而して、図11はクリアランスC3が最大までに拡大した場合にあっても、前記スライド内壁14の下部には、第二の目地カバー部材7上に目立たない極小の間隙を有するスライド用隙間部17が設けられていることがら、エキスパンションジョイントが水平Y方向変位を受けてYスライド方向の矢印38に示す動きをした場合に、前記スライド可動内壁14はYスライド方向の矢印38の円滑な動きが可能であり、前記エキスパンションジョイント床面部材10とエキスパンションジョイント内壁面部材12との取り合いは、非常に狭いスライド用間隙部17の間隙を有するのみの構成となることから、意匠的に大変シンプルできれいな納まりを提供することができる。 FIG. 11 is a perspective view of the state of FIG. 10, 37 is an arrow in the X slide direction indicating movement corresponding to the displacement in the horizontal X direction, and 38 is a movement in the Y slide direction indicating movement corresponding to the displacement in the horizontal Y direction. In the expansion joint inner wall member 12 shown by an arrow, reference numeral 13 denotes a passage inner wall constructed on the frame of the building B. The passage inner wall 13 is provided with a slide movable inner wall 11 slidable. A fixed inner wall 15 is installed at the front end portion of the movable inner wall 14 via a contact joint material 15 provided oppositely. Further, in the expansion joint floor member 10, 8 is a floor surface on the building A side, 18 is a joint plate, 6 is a first joint cover member, 31 is a joint plate, 5 is a base substrate, and 7 is a second joint cover. Reference numeral 33 denotes a joint plate, 36 denotes a sliding groove, and 9 denotes a floor surface on the building B side. Thus, in FIG. 11, even when the clearance C3 is expanded to the maximum, a slide gap portion having a minimal gap that is not conspicuous on the second joint cover member 7 at the lower portion of the slide inner wall 14. 17, when the expansion joint receives the displacement in the horizontal Y direction and moves as indicated by the arrow 38 in the Y slide direction, the slide movable inner wall 14 has a smooth movement of the arrow 38 in the Y slide direction. The expansion joint floor surface member 10 and the expansion joint inner wall surface member 12 are configured to have only a very narrow gap 17 for the slide, so that the design is very simple and clean. Can provide a payment.
而して、図10及び図11は、クリアランスC3が地震の揺れにより最大限までに拡大した場合における第一の目地カバー部材6と第二の目地カバー部材7の設置状況を説明してきたが、クリアランスC3の状況において、水平Y方向変位に対応した矢印41や矢印42の横揺れが発生した場合にはおいては、建物Aと建物B間には、図12と図13に示すような水平Y方向変位が生じる。 Thus, FIGS. 10 and 11 have described the installation status of the first joint cover member 6 and the second joint cover member 7 when the clearance C3 is expanded to the maximum due to the shaking of the earthquake. In the situation of the clearance C3, when the roll of the arrow 41 or the arrow 42 corresponding to the displacement in the horizontal Y direction occurs, the horizontal Y as shown in FIGS. 12 and 13 is formed between the building A and the building B. Directional displacement occurs.
図12と図13は第一の目地カバー部材6と第二の目地カバー部材7の先端部がベース基板5上で離間しており、第一の目地カバー部材6はベース基板5上に載置され床面8と同一面上に設置されている。図12は、建物Bが建物Aに対して矢印41方向に移動し建物Bが奥行方向に水平方向変位しており、この場合には、第二の目地カバー部材7の下部に設けられたスライド用ガイド部材31が建物Bの摺動溝36に沿ってスライド可動することにより、第二の目地カバー部材7は第一の目地カバー部材6と同一位置となり、エキスパンションジョイント床面部材10を円滑に動作可能である。また、図13においては、建物Bが矢印42方向に移動した場合を示し(建物Bが手前方向に水平方向変位)、この場合には、建物Bに支持されているスライド可動内壁14が建物Bと共に矢印42方向に移動するのでエキスパンションジョイント床面部材10とエキスパンションジョイント内壁面部材12は互いに衝突することなく水平Y方向変位、即ち、矢印41方向と矢印42方向の動きに対応することができる。 12 and 13, the tip ends of the first joint cover member 6 and the second joint cover member 7 are separated on the base substrate 5, and the first joint cover member 6 is placed on the base substrate 5. And installed on the same plane as the floor 8. FIG. 12 shows that the building B moves in the direction of the arrow 41 with respect to the building A and the building B is displaced in the horizontal direction in the depth direction. In this case, the slide provided at the lower part of the second joint cover member 7 When the guide member 31 is slid along the sliding groove 36 of the building B, the second joint cover member 7 is located at the same position as the first joint cover member 6, and the expansion joint floor member 10 is smoothly moved. It is possible to operate. FIG. 13 shows a case where the building B moves in the direction of the arrow 42 (the building B is displaced horizontally in the front direction). In this case, the slide movable inner wall 14 supported by the building B is the building B.
