【発明の属する技術分野】
本発明は渡り通路用床目地装置に関する。
【０００２】
【従来の技術】
従来、渡り通路用床目地装置は一方の渡り通路の目地部寄りの部位の床躯体に凹部を形成して固定された下地レ−ルと、この下地レ−ルのほぼ中央部に先端部が位置し、後端部が他方の渡り通路の目地部寄りの床躯体に固定された目地プレ−トと、この目地プレ−トの先端部および前記下地レ−ルの上部を覆うように、該下地レ−ルに固定されたカバ−プレ−トとで構成されている。
【０００３】
【発明が解決しようとする課題】
従来の渡り通路用床目地装置は、地震等によって左右の建物の異なる前後左右方向の揺れ動きを吸収することができるが、前後方向に揺れ動いた場合、目地プレ−トが他方の建物と一体になって前後方向に移動するため、一方の建物側の前後端部に目地プレ−トのない隙間が生じ、危険になるという欠点があった。
【０００４】
本発明は以上のような従来の欠点に鑑み、左右の建物が異なる前後左右方向に揺れ動いても、その揺れ動きを吸収することができるとともに、目地部に隙間が生じても危険になるのを確実に防止でき、かつ固定的な手摺の設置ができ、全体を異なる前後方向に回動させて安全に使用することができる渡り通路用床目地装置を提供することを目的としている。
【０００５】
本発明の前記ならびにそのほかの目的と新規な特徴は次の説明を添付図面と照らし合わせて読むと、より完全に明らかになるであろう。
ただし、図面はもっぱら解説のためのものであって、本発明の技術的範囲を限定するものではない。
【０００６】

【０００９】
前記左右の滑りプレ−ト５、５は図４に示すように、前記左右の渡り通路４、４の目地部３側の床躯体４ａ、４ａを覆う板状の滑りプレ−ト本体１３と、この滑りプレ−ト本体１３の両端部より下方へ突出するように一体形成され、複数本のビス１４等によって床躯体４ａに固定される係止片１５、１５とで構成されている。
【００１０】
前記中央維持機構８は図５に示すように、対向する先端部側にラック１６、１６が形成され、後端部に枢支ピン挿入孔１７、１７が形成された一対の作動杆１８、１８と、この一対の作動杆１８、１８のラック１６、１６の中央部に噛み合うピニオン１９と、このピニオン１９の軸２０に取付けられた前記一対の作動杆１８、１８がスライド移動可能で、該ピニオン１９との噛み合いが外れるのを防止する中央維持片６と、この中央維持片６の下端部より外方に突出して複数本のビス２１等によって前記前後部支持体９、９を支持する支持片２２、２２とで構成されている。
【００１１】

なお、本発明の実施の形態では前後部支持体９、９の軽量化を図るために、複数本のバ−部材２３、２３、２３を用いたものについて説明したが、本発明はこれに限らず、チャンネル状の鋼板あるいは波板鋼板を用いてもよい。
【００１２】
前記目地プレ−ト１１は図７に示すように、前記前後部支持体９、９および前記中央維持機構８の上部を覆う板状のステンレス、ステンレス合金、アルミ合金等の金属材で形成された目地プレ−ト本体２５と、この目地プレ−ト本体２５の前後端部より下方へ突出するように一体形成された、前記前後部支持体９、９に複数本の皿ビス１０等によって固定される前後部カバ−２６、２６と、前記目地プレ−ト本体２５の左右端部より順次下方へ傾斜するように一体形成成された左右端カバ−２７、２７とで構成されている。
【００１３】
上記構成の渡り通路用床目地装置１は地震等によって、左右の渡り通路４、４の目地部３が広くなるように揺れ動いた場合には、図８に示すように左右の滑りプレ−ト５、５が左右の渡り通路４、４と一体になって左右方向に移動するため、該左右の滑りプレ−ト５、５に支持されている前後部支持体９、９および目地プレ−ト１１は中央維持機構８の中央維持片６によって、目地部３の中央部に中央部が位置するように支持されているため、前後部支持体９、９の左右端部が左右の滑りプレ−ト５、５上をスライド移動して、その揺れ動きを吸収する。
また、目地部３が狭くなるように揺れ動いた場合にも、同様に図９に示すように前後部支持体９、９の左右端部が左右の滑りプレ−ト５、５上をスライド移動して、その揺れ動きを吸収する。
【００１４】
左右の渡り通路４、４が異なる前後方向に揺れ動いた場合には、図１０に示すように枢支ピン７、７を支点に中央維持機構８、前後部支持体９、９および目地プレ−ト１１が一体状態となって回動して、その揺れ動きを吸収する。

Claims

Left and right sliding plates fixed on the floor frame on the joint side of the right and left crossing passages formed in the left and right buildings so that they can communicate with each other via the joint, and are supported by the left and right sliding plates. Even if the center maintenance piece at the center part swings in the left and right directions where the left and right buildings are different, both ends located substantially at the center part of the joint part are substantially at the center part on the side opposite to the joint part of the left and right sliding plates. A center support mechanism pivotally supported by a pivot pin attached to the center support mechanism, and both ends of the center support mechanism mounted on the center support piece are slidably supported by the left and right sliding plates. The front and rear support members for supporting the front and rear portions of the mechanism, and the left and right ends attached to the front and rear support members so as to cover the front and rear support members and the center maintaining mechanism are the right and left slide plates or the right and left slide plates. Joints located on the floor frame of the right and left crosswalk - gangway floor joints apparatus characterized by comprising a preparative.

At the center of the floor frame on the joint side of the right and left cross passages formed in the left and right buildings so that they can communicate via the joint, the center maintenance piece at the center where both ends are pivotally supported by pivot pins Even if the left and right buildings swing in different left and right directions, a center maintaining mechanism located at a substantially central portion of the joint, and both ends attached to a center maintaining piece of the center maintaining mechanism have floor joints on the joint side. A front and rear support for supporting the front and rear portions of the center maintaining mechanism, to which a roller is attached so as to be slidable on the top, and the front and rear support to cover the front and rear support and the center maintenance mechanism. A floor joint device for a cross passage, wherein the left and right ends attached to the body comprise joint plates located on the floor frame of the left and right cross passages.

3. A floor joint device for a cross passage according to claim 1, wherein a joint plate having left and right ends formed on inclined surfaces is used.
