Description

【０００１】
【発明の属する技術分野】
本発明は免震ビル等の床面と目地部を介して設けたよう壁等の床面との間を覆う床用目地装置に関する。
【０００２】
【従来の技術】
従来のこの種の床用目地装置は、目地プレートの後端部を一方の床躯体に支持させ、先端部を他方の床躯体の目地部側の上面に反目地部側が傾斜面の目地プレート支持凹部に支持させる構造になっている。
【０００３】
【発明が解決しようとする課題】
従来の床用目地装置は地震等によって目地部が大きく広がった場合に、目地プレートが目地部に落下する危険があるとともに、この危険を防止するためには目地プレートの先端部を大きく他方の目地プレート支持凹部で支持しなければならず、目地プレートが大きくなるとともに、目地プレート支持凹部が大きくなりコスト高になるととともに、設置作業に手数がかか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、目地プレートが大きくなることなく、目地部が広くなっても目地プレートが目地部へ落下したりすることなく、安全に使用することができる、安価で、容易に設置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】

【０００９】
前記目地プレート支持部７は一方の床躯体３に凹部７ａを形成して、そのまま使用してもよいが、該凹部７ａを覆うように複数本のビス１４等で固定される金属材製のほぼクランク状に曲げ形成された目地プレート支持金具本体１５と、この目地プレート支持金具本体１５の底面部に形成された複数個の軸挿入孔１０とからなる目地プレート支持金具１６を用いる。
【００１０】

【００１１】
前記目地プレート１２は先端部が前記目地プレート支持凹部９の傾斜面８と面接触する傾斜面１８に形成された金属材製の浅皿状の目地プレート本体１９と、この目地プレート本体１９内にモルタル２０等を介して固定された床タイル等の床化粧材２１とで構成されたものが使用されている。
【００１２】

【The invention's effect】
As is clear from the above description, the present invention has the following effects.
[0025]
(1) A joint plate support portion formed at the tip of one floor casing projecting outward, and the other floor casing provided via the one floor casing projecting outward and the crank joint section. The joint plate side is formed with an inclined joint plate support concave portion formed on the joint portion side upper portion, and the rear end portion is supported by the joint plate support portion so that the tip portion covering the joint plate support concave portion can be rotated upward. And a plurality of slidable supports that support the joint plate slidably supported on the other floor housing part of the joint located between the one floor housing and the other floor housing. Support pillars, guide rods attached to substantially the center portions of the plurality of support pillars so as to protrude in the horizontal direction, and the one floor frame in which these guide rods are slidably inserted in the horizontal direction. Or a guide hole formed in the horizontal direction in the other floor frame, and a biasing spring that constantly biases the plurality of support columns respectively accommodated in these guide holes in a direction protruding toward the joint portion side. Therefore, when the joint portion becomes wide due to an earthquake or the like, the portion near the tip of the joint plate can be supported by the joint plate support mechanism.
Therefore, the accident that the front-end | tip part of a joint plate falls into a joint part can be prevented reliably, and it can be used safely.
[0026]
(2) When the joint portion is narrowed by the above (1), the joint plate support mechanism contracts, so that the joint portion is not obstructed to move and the large joint portion is secured. be able to.
[0027]
(3) According to the above (1), since the structure is simple, it can be easily implemented.
[0028]
(4) In the second and third aspects, the same effects as in the above (1) to (3) can be obtained.
