Description

本発明は目地部を介して設けられた左右の建物を連通する通路を形成する部位の床用目地装置に関する。   The present invention relates to a floor joint device that forms a passage that communicates between left and right buildings provided through joint portions.

従来、この種の床用目地装置は一方の建物の目地部側床躯体にほぼ水平方向に固定されたガイドレールと、このガイドレールに後端部がスライド移動可能に支持され、先端部が他方の建物の目地部側通路の床面上を左右方向にスライド移動可能に支持された目地プレートとで構成されている。   Conventionally, this type of floor joint device is supported by a guide rail that is fixed substantially horizontally to the joint side floor frame of one building, and a rear end portion of the guide rail that is slidably supported. And a joint plate supported so as to be slidable in the left-right direction on the floor of the joint-side passage of the building.

このため、目地プレートの幅寸法は他方の建物の床面の幅寸法と同じ幅寸法であるため、両方の建物が異なる前後方向に揺れ動いた場合には、他方の建物の通路の両端部のいずれか一方側の床面に隙間が生じたり、他方の建物の通路の一方の端部側が目地プレート以外の部位に開口してしまうという欠点があった。
この欠点を解消するために、目地プレートの両側にカバープレートを設けたり、他方の建物の通路側をスライド移動時に塞ぐL字状のカバープレートを設置することも行なわれているが、通路が狭くなったり、目地プレートが重くなり、スムーズな移動を確保することができなくなるという欠点があった。
なし
For this reason, the width dimension of the joint plate is the same as the width dimension of the floor of the other building, so if both buildings swing in different longitudinal directions, either of the two ends of the passage of the other building There is a drawback that a gap is formed on the floor surface on one side or that one end side of the passage of the other building opens to a portion other than the joint plate.
In order to eliminate this drawback, cover plates are provided on both sides of the joint plate, or an L-shaped cover plate is installed to block the passage side of the other building when sliding, but the passage is narrow. Or the joint plate becomes heavy, and there is a disadvantage that smooth movement cannot be secured.
None

本発明は以上のような従来の欠点に鑑み、両方の建物が異なる前後方向に揺れ動いても、目地部の通路が狭くなることなく、かつ目地プレートも重くなることなく、スムーズにスライド移動させて、地震等の揺れ動きを損傷することなく吸収することができる床用目地装置を提供することを目的としている。   In view of the above-mentioned conventional drawbacks, the present invention can smoothly slide and move both the buildings swinging in different front and rear directions without narrowing the passage of the joint and without increasing the joint plate. An object of the present invention is to provide a floor joint device capable of absorbing a shaking motion such as an earthquake without damaging it.

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。

A support recess that is approximately twice the space between joints formed on the floor surface of the part where the outer wall is formed, and the joint part side of the other building that corresponds to the part where the support recess is formed via the joint A guide rail attached to the floor frame of the main body so that it can be guided in a substantially horizontal direction, and a rear end portion of the guide rail is supported so as to be slidable, and a front end portion is supported so as to be movable in a substantially central portion of the support recess. And a cover plate that covers the tip of the joint plate and the support recess so that the joint plate can be moved. , A pinion attached to a portion near the rear end of the joint plate, a joint side floor frame of the one building meshing with the pinion, and a pair of racks pivotally supported by the joint side floor frame of the other building A floor joint device is constituted by the central maintenance mechanism provided.

以上の説明から明らかなように、本発明にあっては次に列挙する効果が得られる。   As is clear from the above description, the present invention has the following effects.

Therefore, durability can be improved without being damaged.

(2)両方の建物が異なる前後方向に揺れ動いた場合には、目地プレートが中心維持機構によって前後方向に移動させられるため、内壁間に目地プレートが位置するように移動させることができる。
したがって、従来のように目地プレートの移動によって隙間が生じて危険になったりするのを確実に防止することができるとともに、目地部の通路の幅寸法が小さくなったりするのを確実に防止することができる。
(2) When both buildings swing in different front and rear directions, the joint plate is moved in the front and rear direction by the center maintaining mechanism, so that the joint plate can be moved between the inner walls.
Therefore, it is possible to reliably prevent a gap from being generated due to the movement of the joint plate as in the prior art, and to prevent a reduction in the width dimension of the joint passage. Can do.
