Description

本発明は、第一建物の第一床面と第二建物の第二床面が、互いに近接および離間する遠近方向とその遠近方向にほぼ直交する横方向に相対移動可能なように、前記第一床面と第二床面を互いに連結するエキスパンションジョイント床パネルに関する。   In the present invention, the first floor surface of the first building and the second floor surface of the second building are relatively movable in the perspective direction approaching and separating from each other and in the lateral direction substantially perpendicular to the perspective direction. The present invention relates to an expansion joint floor panel that connects one floor surface and a second floor surface to each other.

このような床パネルは、例えば、地震の発生によって第一建物の第一床面と第二建物の第二床面が相対的に移動したとき、両床面間の相対移動を許容しながら、両床面間を繋ぐ通路を確保するためのもので、従来から種々の構造の床パネルが提案されている。
さらに、この種の床パネルでは、両床面が横方向に相対移動したときに通路面を如何にして確保するかが大きな問題であり、かかる問題を解消するため、種々の構造からなる床パネルも提案されている（例えば、特許文献１〜３参照）。 Such floor panels, for example, when the first floor surface of the first building and the second floor surface of the second building are moved relative to each other due to the occurrence of an earthquake, while allowing relative movement between both floor surfaces, In order to secure a passage connecting both floor surfaces, floor panels having various structures have been proposed.
Furthermore, in this type of floor panel, it is a big problem how to secure the passage surface when both floor surfaces are moved relative to each other in the lateral direction. Has also been proposed (see, for example, Patent Documents 1 to 3).

特開２００３−２３９４０５号公報JP 2003-239405 A 特開２０００−９６７１４号公報JP 2000-96714 A 特許第３０９５３５９号公報Japanese Patent No. 3095359

しかし、上記特許文献１〜３に記載のエキスパンションジョイント床パネルをはじめとして、従来から知られているエキスパンションジョイント床パネルは、いずれも総じて部品点数が多く、構造的に複雑なものばかりであった。
したがって、従来の床パネルは、コスト面で高価なものとなり、しかも、部品点数が多くて構造的に複雑であるがゆえに、実際に地震が発生した際、所望どおりに作動しないという危惧もあり、この点に改良の余地があった。 However, the expansion joint floor panels conventionally known including the expansion joint floor panels described in Patent Documents 1 to 3 generally have a large number of parts and are structurally complicated.
Therefore, the conventional floor panel is expensive in terms of cost, and because it has a large number of parts and is structurally complicated, there is a concern that it does not operate as desired when an earthquake actually occurs, There was room for improvement in this regard.

本発明は、このような従来構造の問題点に着目したもので、その目的は、部品点数を極力少なくして構造の簡素化を図り、地震発生時において所望どおりに作動するエキスパンションジョイント床パネルを提供することにある。   The present invention focuses on the problems of such a conventional structure, and its purpose is to reduce the number of parts as much as possible to simplify the structure and to provide an expansion joint floor panel that operates as desired in the event of an earthquake. It is to provide.

本発明の第１の特徴構成は、第一建物の第一床面と第二建物の第二床面が、互いに近接および離間する遠近方向とその遠近方向にほぼ直交する横方向に相対移動可能なように、前記第一床面と第二床面を互いに連結するエキスパンションジョイント床パネルであって、前記床パネルが、ほぼ矩形の矩形プレートとほぼ三角形の三角形プレートを備え、前記矩形プレートの一端側が、前記第一床面側に固定のスライド機構を介して前記横方向にスライド自在に係合され、他端側が前記遠近方向に移動自在に前記第二床面上に載置されるとともに、前記三角形プレートの一辺側が前記第一床面側に固定され、前記矩形プレートと三角形プレートが、その厚み方向を上下方向に重ねて近接して配置されているところにある。   In the first characteristic configuration of the present invention, the first floor surface of the first building and the second floor surface of the second building are relatively movable in the perspective direction close to and away from each other and in the lateral direction substantially orthogonal to the perspective direction. An expansion joint floor panel connecting the first floor surface and the second floor surface to each other, wherein the floor panel comprises a substantially rectangular rectangular plate and a substantially triangular triangular plate, and one end of the rectangular plate The side is slidably engaged in the lateral direction through a sliding mechanism fixed to the first floor surface side, and the other end side is placed on the second floor surface movably in the perspective direction, One side of the triangular plate is fixed to the first floor surface side, and the rectangular plate and the triangular plate are arranged close to each other with their thickness directions overlapped in the vertical direction.

本発明の第１の特徴構成によれば、第一建物の第一床面と第二建物の第二床面を相対移動可能に連結するエキスパンションジョイント床パネルが、ほぼ矩形の矩形プレートを備え、その矩形プレートの一端側が、第一床面側に固定のスライド機構を介して横方向にスライド自在に係合され、他端側が遠近方向に移動自在に第二床面上に載置されているので、両床面が横方向に相対移動する場合には、矩形プレートの一端側がスライド機構を介して第一床面に対して横方向にスライドし、両床面が遠近方向に相対移動する場合には、矩形プレートの他端側が第二床面上を遠近方向に移動する。
したがって、両床面が横方向または遠近方向に相対移動する場合は勿論のこと、両床面が斜め方向に相対移動する場合には、両床面間の横方向への相対スライドと遠近方向への相対移動との複合的な動きによって、両床面間の斜め方向への相対移動も許容することになる。 According to the first characteristic configuration of the present invention, the expansion joint floor panel that connects the first floor surface of the first building and the second floor surface of the second building so as to be relatively movable includes a substantially rectangular plate, One end side of the rectangular plate is slidably engaged in the lateral direction via a slide mechanism fixed to the first floor surface side, and the other end side is placed on the second floor surface so as to be movable in the perspective direction. Therefore, when both floor surfaces move relative to each other in the horizontal direction, one end of the rectangular plate slides laterally relative to the first floor surface via the slide mechanism, and both floor surfaces move relative to each other in the perspective direction. The other end side of the rectangular plate moves in the perspective direction on the second floor surface.
Therefore, when both floor surfaces move relative to each other in the horizontal direction or the perspective direction, when both floor surfaces move relative to each other in the oblique direction, the relative sliding in the horizontal direction between the both floor surfaces and the perspective direction are performed. The relative movement in the oblique direction between both floor surfaces is allowed by the combined movement with the relative movement of the two floors.

さらに、この矩形プレートに加えて、ほぼ三角形の三角形プレートも備えていて、三角形プレートの一辺側が第一床面側に固定され、矩形プレートと三角形プレートが、その厚み方向を上下方向に重ねて近接して配置されているので、両床面が横方向や斜め方向に相対移動した場合、三角形プレートの一部が矩形プレートから横側方に突出して、矩形プレートの移動により空隙化するおそれのある部分を覆って通路部分を確保する。
したがって、矩形プレートと三角形プレート、さらに、スライド機構からなる簡単な構造でエキスパンションジョイント床パネルを構成することができ、それによってコストの低廉化が可能となり、しかも、地震発生時においては、両床面間での相対移動方向の如何にかかわらず通路面を確実に確保することができる。 In addition to this rectangular plate, a triangular plate is also provided. One side of the triangular plate is fixed to the first floor, and the rectangular plate and the triangular plate are close to each other with their thickness directions stacked vertically. Therefore, when both floor surfaces move relative to each other in the horizontal or diagonal direction, a part of the triangular plate may protrude laterally from the rectangular plate, resulting in a gap due to the movement of the rectangular plate. Cover the part and secure the passage part.
Therefore, the expansion joint floor panel can be configured with a simple structure consisting of a rectangular plate, a triangular plate, and a sliding mechanism, thereby reducing the cost, and in the event of an earthquake, both floor surfaces The passage surface can be surely secured regardless of the relative movement direction between the two.

本発明の第２の特徴構成は、前記矩形プレートが前記三角形プレートの上方に配置され、その矩形プレートとほぼ同形の下プレートが、その厚み方向を前記矩形プレートと三角形プレートの厚み方向に重ねて前記三角形プレートの下方に近接して配置され、その下プレートの一端側が、前記スライド機構を介して前記横方向にスライド自在に係合され、他端側が前記遠近方向に移動自在に前記第二床面上に載置されているところにある。   According to a second characteristic configuration of the present invention, the rectangular plate is disposed above the triangular plate, and a lower plate having substantially the same shape as the rectangular plate overlaps the thickness direction of the rectangular plate and the triangular plate. The second floor is disposed adjacent to the lower side of the triangular plate, and one end side of the lower plate is slidably engaged in the lateral direction via the slide mechanism, and the other end side is movable in the perspective direction. It is located on the surface.

本発明の第２の特徴構成によれば、矩形プレートが三角形プレートの上方に配置されているので、通常時においては、その矩形プレートが通路の上面となり、段差のない通路面の確保が可能となる。
そして、その矩形プレートとほぼ同形の下プレートが、その厚み方向を矩形プレートと三角形プレートの厚み方向に重ねて三角形プレートの下方に近接して配置され、その下プレートの一端側が、スライド機構を介して横方向にスライド自在に係合され、他端側が遠近方向に移動自在に第二床面上に載置されているので、下プレートは、下方から三角形プレートを支持しながら矩形プレートとほぼ同じ動きをすることになり、地震発生時においても三角形プレートを下方から確実に支持する。 According to the second characteristic configuration of the present invention, since the rectangular plate is disposed above the triangular plate, in normal times, the rectangular plate is the upper surface of the passage, and it is possible to secure a passage surface without a step. Become.
A lower plate that is substantially the same shape as the rectangular plate is arranged close to the lower side of the triangular plate with its thickness direction overlapped with that of the rectangular plate and the triangular plate, and one end side of the lower plate is interposed via a slide mechanism. Since the other end is mounted on the second floor so as to be movable in the perspective direction, the lower plate is substantially the same as the rectangular plate while supporting the triangular plate from below. It will move, and it will support the triangular plate from below even when an earthquake occurs.

本発明の第３の特徴構成は、前記スライド機構が、上方に開口する断面コの字状のレール材で構成され、前記矩形プレートの一端側に連設のスライド部材と前記下プレートの一端側に連設のスライド部材が、前記レール材にそれぞれ係合され、前記三角形プレートの一辺側が前記レール材に固定されているところにある。   According to a third characteristic configuration of the present invention, the slide mechanism is configured by a U-shaped rail member that opens upward, and a slide member continuously provided on one end side of the rectangular plate and one end side of the lower plate. Are connected to the rail member, and one side of the triangular plate is fixed to the rail member.

本発明の第３の特徴構成によれば、スライド機構が、上方に開口する断面コの字状のレール材で構成され、矩形プレートの一端側に連設のスライド部材と下プレートの一端側に連設のスライド部材がレール材にそれぞれ係合されているので、断面コの字状のレール材からなる比較的簡単な構造のスライド機構によって、矩形プレートと下プレートの横方向への相対スライドが可能となる。
そして、そのレール材に対して三角形プレートの一辺側も固定されているので、断面コの字状のレール材に対して矩形プレート、下プレート、および、三角形プレートの全てが関連付けられて、構造の簡素化と作動の確実性が確保される。 According to the third characteristic configuration of the present invention, the slide mechanism is configured by a U-shaped rail member that opens upward, and is provided on one end side of the rectangular plate and on one end side of the lower plate. Since the continuous slide members are respectively engaged with the rail members, the slide mechanism having a relatively simple structure made of a rail member having a U-shaped cross-section allows the rectangular plate and the lower plate to slide relative to each other in the lateral direction. It becomes possible.
Since one side of the triangular plate is fixed to the rail material, the rectangular plate, the lower plate, and the triangular plate are all associated with the U-shaped rail material of the cross-section. Simplification and operational certainty are ensured.

The rail member 6 is configured to function as a slide mechanism.
Further, a metal channel material 7 as a slide member is attached to one end side of the rectangular plate 2, that is, an edge portion on one end side located on the first floor surface F <b> 1 side, and the first floor surface of the triangular plate 3. On one side of the F1 side, an attachment piece 3a formed by bending in an L shape downward is integrally provided. Moreover, the edge part by the side of the 1st floor surface F1 of the lower plate 4 is bend | folded toward the downward direction, and it is comprised so that the bending part 4a may function as a slide member, The 2nd floor surface F2 side of the lower plate 4 A gap holding member 8 made of CR rubber having a thickness slightly larger than the thickness of the triangular plate 3 is attached to the upper surface of the edge portion by an adhesive.

床パネル１を構成する３枚のプレート２，３，４は、矩形プレート２が最上方に、三角形プレート３が中間に、下方プレート４が最下方に位置するように、その厚み方向を上下方向に重ね、かつ、互いに近接するように積み重ねて配置されている。
そして、矩形プレート２のチャンネル材７と下プレート４の折曲部４ａが、スライド機構を構成するコの字状レール材６の中空部内に係合載置されて、両プレート２，４の第一床面Ｆ１側端部が、横方向Ｙにスライド自在に係合され、両プレート２，４の他端部が、遠近方向Ｘに移動自在に第二床面Ｆ２上に載置されている。また、三角形プレート３の取り付け片３ａは、チャンネル材７と折曲部４ａの間に位置してレール材６に固定され、レール材６の開口部が、レール材６に固定された金属製の帯材９により閉鎖されている。

It is closed by a strip 9.
Note that a chain attachment bracket 10 is attached to both buildings B1 and B2, and a chain 11 stretched between the chain attachment brackets 10 is arranged so as to be positioned on the left and right lateral sides of the floor panel 1.

つぎに、このエキスパンションジョイント床パネル１の作動について説明する。
この床パネル１は、通常、図５の（イ）に示す状態にあり、地震の発生によって、両建物Ｂ１，Ｂ２が遠近方向Ｘに沿って互いに離間する方向に相対移動すると、下プレート４と矩形プレート２の第二床面Ｆ２側端部が、遠近方向Ｘに沿って第二床面Ｆ２上を移動して図５の（ロ）に示す状態となる。
逆に、両建物Ｂ１，Ｂ２が互いに近接する方向に相対移動すると、図５の（ハ）に示す状態となり、いずれの場合にも、チェーン１１内の通路部分は、矩形プレート２と下プレート４により完全に閉鎖された状態となる。 Next, the operation of the expansion joint floor panel 1 will be described.
