Description

本発明は目地部を介して設けられた免震ビル等の左右の建物の床部分の目地部を覆う床用目地装置に関する。   The present invention relates to a floor joint device for covering joint portions of floor portions of left and right buildings such as seismic isolation buildings provided via joint portions.

従来、免震ビル等で、目地部の左右方向の寸法の2倍よりも小さな範囲で移動量を設定することができない現場には、目地部の左右方向の寸法の2倍以下の目地プレートしか設置することができず、目地部の左右方向の寸法およびそれ以上の移動量を設定することができないという欠点があった。
特になし。
Conventionally, in a seismic isolation building, etc., where the amount of movement cannot be set in a range smaller than twice the horizontal dimension of the joint, only joint plates that are less than twice the horizontal dimension of the joint are available. There is a drawback that it cannot be installed, and the dimension of the joint portion in the left-right direction and the amount of movement beyond that cannot be set.
nothing special.

本発明は以上のような従来の欠点に鑑み、目地部の左右方向の寸法の2倍よりも小さな範囲でしか移動量を設定することができない現場でも、目地部の左右方向の寸法分以上の伸縮移動量の設定が可能な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-described conventional drawbacks, the present invention is more than the horizontal dimension of the joint part even in the field where the movement amount can be set only within a range smaller than twice the lateral dimension of the joint part. An object of the present invention is to provide a floor joint device capable of setting the amount of expansion and contraction movement.

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。
The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are for explanation only and do not limit the technical scope of the present invention.

上記目的を達成するために、本発明は目地部を介して設けられた左右の建物の、一方の建物の目地部側の躯体に後端部が取付けられ、先端部が他方の建物の目地部側の床面上をスライド移動できる、該目地部の左右方向の寸法の約2倍の長さの目地プレートと、前記他方の建物の目地部側の床躯体に取付けられた、常時は該目地部側の床躯体より目地部内へ突出し、地震等によって目地部が狭くなると前記一方の建物の目地部側の躯体によって押し圧されて収縮する、前記目地プレートを支持する目地プレート支持具とで床用目地装置を構成している。   In order to achieve the above object, according to the present invention, a rear end portion is attached to a joint on the joint portion side of one building of the left and right buildings provided via the joint portion, and a tip portion is a joint portion of the other building. A joint plate that is slidable on the floor surface of the side and is approximately twice as long as the dimension of the joint in the left-right direction, and is attached to the floor frame on the joint portion side of the other building. It protrudes into the joint part from the floor housing on the part side, and when the joint part becomes narrow due to an earthquake or the like, it is pressed and contracted by the joint on the joint part side of the one building, and the floor with the joint plate supporter that supports the joint plate This constitutes a joint device.

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.

(1)一方の建物の目地部側の躯体に後端部が取付けられ、先端部が他方の建物の目地部側の床面上をスライド移動できる、該目地部の左右方向の寸法の約2倍の長さの目地プレートと、前記他方の建物の目地部側の床躯体に取付けられた、常時は該目地部側の床躯体より目地部内へ突出し、地震等によって目地部が狭くなると前記一方の建物の目地部側の躯体によって押し圧されて収縮する、前記目地プレートを支持する目地プレート支持具とで構成されているので、地震等によって目地部の左右方向の寸法以上に左右の建物が揺れ動いて目地部が広くなった場合には、他方の建物の目地部側の床躯体に取付けられた、常時目地部へ突出する目地プレート支持具で目地プレートの先端部を支持することができる。
また、目地部の左右方向の寸法がなくなるように狭くなった場合には、目地プレート支持具を一方の建物の躯体によって、他方の建物の床躯体へ押し圧して収縮させることができる。
したがって、目地部の左右方向の寸法分だけの収縮を可能にすることができる。
(1) The rear end portion is attached to the joint on the joint portion side of one building, and the tip portion can slide on the floor surface on the joint portion side of the other building. A joint plate having a double length and the floor frame on the joint part side of the other building is normally projected into the joint part from the floor part on the joint part side, and when the joint part becomes narrow due to an earthquake or the like, the one side The joint is supported by the joint plate supporter that supports the joint plate and is contracted by being pressed by the joint on the joint part side of the building. When the joint part is widened by shaking, the tip part of the joint plate can be supported by the joint plate support tool that is attached to the floor frame on the joint part side of the other building and always projects to the joint part.
Further, when the joint portion is narrowed so that the dimension in the left-right direction is eliminated, the joint plate support can be contracted by being pressed against the floor housing of the other building by the housing of one building.
Therefore, contraction by the dimension in the horizontal direction of the joint portion can be made possible.

(2)前記(1)によって、目地部の左右方向の寸法の2倍よりも小さな範囲でしか移動量を設定することができない現場でも、目地部の左右方向の寸法の2倍以下の目地プレートを用いて、目地部の左右方向の寸法とほぼ同じ寸法分だけ目地部が広くなったり、狭くなっても、目地部に隙間が生じることなく、かつ目地プレートが元の状態に自動的に戻れる状態で、その揺れ動きを吸収することができる。 (2) According to (1), a joint plate that is less than twice the horizontal dimension of the joint part even at a site where the amount of movement can be set only in a range smaller than twice the lateral dimension of the joint part. , Even if the joint is widened or narrowed by the same dimension as the horizontal dimension of the joint, there is no gap in the joint and the joint plate can automatically return to its original state. The state can absorb the shaking motion.

(3)前記(1)によって、目地プレート支持具を設けるだけでよいので、構造が簡単で、容易に実施することができる。 (3) According to the above (1), it is only necessary to provide a joint plate support, so that the structure is simple and can be implemented easily.

(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.
