Description

本発明は左右の躯体に設けられた通路を、目地部を介して接続する床用目地装置に関する。   The present invention relates to a floor joint device for connecting passages provided in left and right housings through joint portions.

従来、この種の床用目地装置は左右の躯体の通路に対し、直交するように形成された目地部を覆うように取付けられている。 Conventionally, this kind of floor joint apparatus is attached so that the joint part formed so that it might orthogonally crossed with respect to the channel | path of the left and right housings.

しかしながら、左右の躯体の通路間に、直交以外の傾斜面となる目地部に床用目地装置を設ける必要が生じた。
この場合、いままでの構成の床用目地装置を用いると、異なる左右方向の揺れ動きは吸収することができるが、異なる前後方向の揺れ動き時には通路の側壁を損傷させたり、目地プレートを損傷させる等の不具合が生じ、使用することができないという欠点があった。 However, it has become necessary to provide a floor joint device between joint passages on the left and right sides at joints that are inclined surfaces other than orthogonal.
In this case, if the floor joint device having the structure as described above is used, it is possible to absorb different lateral shaking motions. There was a drawback that it could not be used due to a problem.

A joint plate slide support portion formed at a joint portion side portion of the passage of one of the housings, and a slide rail provided substantially horizontally at a joint portion side portion of the passage of the other housing corresponding to the joint plate slide support portion And a portion excluding one end portion of the passage supported by the slide rail so that the rear end portion is slidably supported and the tip portion is slidably supported so that the front end portion is positioned at a substantially central portion of the joint plate slide support portion. A movable joint plate that covers the one end of the passage that is slidably attached to one end of the movable joint plate. Alternatively, a sliding joint plate in which a rear end portion provided with a moving means that is moved forward by the pressing force of a roller provided at the part is supported by a passage of the other housing, and a joint portion of the other housing A rear cover plate that slidably covers a rear end portion of the sliding joint plate fixed to the side passage, and a tip of the movable joint plate and the sliding joint plate fixed to the joint portion side passage of the one housing A front cover plate that slidably covers the sliding portion, and a means for moving the sliding joint plate so that it always abuts on a corner portion on the joint portion side of the passage of the other housing or on a roller provided in the portion. The joint device for floors is comprised with the biasing spring which biases.

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.

また、左右の躯体が地震で異なる前後方向に揺れ動いた場合、摺動目地プレートの移動手段が他方の躯体の通路の目地部側の角部あるいは、該部位に設けられたローラの押し圧力で付勢スプリングの付勢力に抗して、前方へスライド移動するとともに、可動目地プレートがスライドレールに沿って前後方向にスライド移動して、その揺れ動きを吸収することができる。 (1) When the left and right housings sway in different left and right directions due to an earthquake or the like, the movable joint plate and the tip of the sliding joint plate slide on the joint plate slide support portion to absorb the shaking motion.
In addition, when the left and right housings sway in different longitudinal directions due to an earthquake, the sliding joint plate moving means is attached by the corner of the joint portion side of the passage of the other housing or by the pressing force of the roller provided at that part. The movable joint plate slides in the front-rear direction along the slide rail and can absorb the swaying motion while sliding forward against the biasing force of the bias spring.

（２）後部カバープレートおよび前部カバープレートで可動目地プレート、摺動目地プレートの前部を覆うとともに、摺動目地プレートの後部を覆っているのできれいに仕上げることができる。 (2) The rear cover plate and the front cover plate cover the front portions of the movable joint plate and the sliding joint plate, and the rear portion of the sliding joint plate.

（３）摺動目地プレートを他方の躯体の通路の目地部側の角部あるいは、該部位に設けられたローラの地震時の異なる前後方向の揺れ動きの押し圧力で前方へスライド移動させるので、構造が簡単で、スムーズに移動させることができる。 (3) Since the sliding joint plate is slid forward by the pressing force of the corner part on the joint part side of the passage of the other housing or the different swaying motion of the roller provided in the part at the time of earthquake, the structure Is easy and can be moved smoothly.

（４）請求項２も前記（１）〜（３）と同様な効果が得られる。 (4) In claim 2, the same effects as in the above (1) to (3) can be obtained.

（５）請求項３も前記（１） 〜（３）と同様な効果が得られるとともに、左右の躯体の通路の床面とほぼ同じ床面となるように設置することができ、安全に使用することができる。 (5) The third aspect of the present invention can provide the same effects as in the above (1) to (3), and can be installed so as to be substantially the same as the floor surface of the left and right frame passages, and can be used safely. can do.
