Description

【０００１】
【発明の属する技術分野】
本発明は目地部を介して設けられた段差部が傾斜面の左右の床躯体間を覆う床用目地装置に関する。
【０００２】
【従来の技術】
従来、目地部を介して設けられた段差部が傾斜面の左右の躯体間を覆う床用目地装置は、平坦部位と傾斜面部位とを分離した複数個の四角形状の目地プレートを用いて覆っている。
【０００３】
【発明が解決しようとする課題】
従来のこの種の床用目地装置は、左右の床躯体が地震等によって目地部が狭くなったり広くなっても、その揺れ動きを吸収することができるが、異なる前後方向に揺れ動いた場合、傾斜面の端部の目地プレートが上部外方に突出するとともに、開口部が生じて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、左右の床躯体が異なる前後左右方向に地震等によって揺れ動いても、目地プレートが外方へ突出して開口部が生じたりするのを確実に防止して、安全に使用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。
【０００５】
