Description

本発明は一方と他方の左右の躯体の天井間の目地部を塞ぐ天井用目地装置に関する。 The present invention relates to a ceiling joint device that closes a joint portion between the ceilings of one and the other left and right skeletons.

従来、この種の天井用目地装置としては、例えば、「目地部を介して建てられた左右の建物の天井目地部を該天井目地部が狭くなる揺れ動き時には上方へ押し上げるように支持することができる、少なくとも２個以上の支持金具に取付けられた天井目地部を覆う天井用目地カバーを備える天井用目地装置において、前記天井用目地カバーを前後方向に摺動可能な少なくとも２個以上に分割された分割天井用目地カバーで構成するとともに、前記少なくとも２個以上の支持金具を前記分割天井用目地カバーをそれぞれ前後方向に摺動可能に支持できるようにしたもの」が知られている（特許文献１）。 Conventionally, as this type of ceiling joint device, for example, "the ceiling joints of the left and right buildings built through the joints can be supported so as to be pushed upward when the ceiling joints are narrowed and shaken. In a ceiling joint device including a ceiling joint cover that covers a ceiling joint portion attached to at least two or more support fittings, the ceiling joint cover is divided into at least two or more slidable in the front-rear direction. A joint cover for split ceilings is provided, and at least two or more support metal fittings are capable of slidably supporting the joint covers for split ceilings in the front-rear direction ”(Patent Document 1). ).

このような天井用目地装置では、地震によって左右の躯体間の天井目地部が狭くなった場合に、天井用目地カバーが上方へせり上がり地震による揺れ動きを吸収するものであるが、天井用目地カバーの両端部が傾斜面状に形成されているとはいえ、地震時には固定天井材に天井用目地カバーの両端部が衝突することで、この天井用目地カバーや固定天井材の底面に設けられる天井ボードや化粧板等に衝突の衝撃でひび割れ、スクラッチ（傷）等が生じるおそれがあった。 In such a ceiling joint device, when the ceiling joint between the left and right skeletons becomes narrow due to an earthquake, the ceiling joint cover rises upward to absorb the shaking motion caused by the earthquake. Although both ends of the ceiling are formed in an inclined surface shape, the ceiling provided on the bottom surface of the joint cover for the ceiling and the fixed ceiling material due to the collision of both ends of the joint cover for the ceiling with the fixed ceiling material in the event of an earthquake. There was a risk of cracks, scratches, etc. on the board, veneer, etc. due to the impact of collision.

特許第３３８２５６７号公報Japanese Patent No. 3382567

本発明は以上のような従来の問題点に鑑み、地震時に躯体等だけでなく天井ボードや化粧板等の破損を防止できる天井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 problems, an object of the present invention is to provide a ceiling joint device capable of preventing damage not only to the skeleton and the like but also to the ceiling board and the decorative board in the event of an earthquake.

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 objectives and novel features of the present invention will become more fully apparent when the following description is read in light of the accompanying drawings.
However, the drawings are for illustration purposes only and do not limit the technical scope of the present invention.

上記目的を達成するために、本発明の請求項１に記載の天井用目地装置は、一方の躯体と、前記一方の躯体に目地部を介して設けられた他方の躯体と、前記一方の躯体及び他方の躯体の左右壁面に所定間隔を有して対向するように設けられた左右１対のガイド手段と、目地プレート支持手段によって支持されるとともに、前記ガイド手段の上部に両端部が略当接状態で設けられた目地プレートとで構成され、前記目地プレートは、目地プレート本体と、この目地プレート本体の両端部にヒンジ部材を介してそれぞれ回動可能に接続された左右一対の端板とからなり、前記ガイド手段の上面には、地震によって前記目地部が狭くなった場合に、前記端板を押圧し、前記ヒンジ部材を支点に上方へ回動させる傾斜面が形成されていることを特徴とする。 In order to achieve the above object, the ceiling joint device according to claim 1 of the present invention includes one skeleton, the other skeleton provided on the one skeleton via a joint portion, and the one skeleton. It is supported by a pair of left and right guide means provided so as to face each other at a predetermined distance on the left and right wall surfaces of the other skeleton and a joint plate supporting means, and both ends are substantially abutted on the upper part of the guide means. The joint plate is composed of a joint plate provided in a contact state, and the joint plate includes a joint plate main body and a pair of left and right end plates rotatably connected to both ends of the joint plate main body via hinge members. The upper surface of the guide means is formed with an inclined surface that presses the end plate and rotates upward with the hinge member as a fulcrum when the joint portion becomes narrow due to an earthquake. It is a feature.

請求項２に記載の天井用目地装置の前記ガイド手段は、前記ヒンジ部材の下方に位置するカバー板を有することを特徴とする。 The guide means of the ceiling joint device according to claim 2 is characterized by having a cover plate located below the hinge member.

請求項３に記載の天井用目地装置の前記ガイド手段の上面は、前記傾斜面が前記ガイド手段の取付端部側に形成されるとともに、前記傾斜面に連続し突出端部に向かって前記傾斜面よりも傾斜が緩い緩斜面が形成されていることを特徴とする。 The upper surface of the guide means of the ceiling joint device according to claim 3 has an inclined surface formed on the mounting end side of the guide means, and is continuous with the inclined surface and inclined toward a protruding end portion. It is characterized in that a gentle slope having a gentler slope than the surface is formed.

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。
（１）請求項１に記載の発明においては、地震によって目地部が狭くなった場合に目地プレート支持手段によって支持されている目地プレートの左右１対の端板がそれぞれ上方に回動して地震による揺れ動きを吸収するため、目地プレート等に加わる衝撃が小さくなり、天井ボード、化粧板等の損傷を確実に防止することができる。
（２）請求項２に記載の発明においては、前記（１）と同様な効果が得られるとともに、ヒンジ部材がガイド手段の上方に位置するため、目地部の下方から上方の天井用目地装置を目視した際に、ヒンジ部材がガイド手段のカバー板で隠れる。
したがって、端板の下方への回動防止のみならず天井部分の美観を向上させることができる。
（３）請求項３に記載の発明においては、前記（１）〜（２）と同様な効果が得られるとともに、地震によって左右の躯体が大きく揺れ動き、目地部が狭くなった場合であっても、その上面が緩斜面によって目地プレート全体が上方へせり上がるとともに、端板を容易に回動させることができる。 As is clear from the above description, the following effects can be obtained in the present invention.
(1) In the invention according to claim 1, when the joint portion is narrowed due to an earthquake, the pair of left and right end plates of the joint plate supported by the joint plate supporting means rotate upward to cause an earthquake. Since the shaking motion due to the above is absorbed, the impact applied to the joint plate and the like is reduced, and damage to the ceiling board, the decorative board and the like can be reliably prevented.
(2) In the invention according to claim 2, the same effect as in (1) above can be obtained, and since the hinge member is located above the guide means, the ceiling joint device from below to above the joint portion is provided. When visually observed, the hinge member is hidden by the cover plate of the guide means.
Therefore, it is possible not only to prevent the end plate from rotating downward but also to improve the aesthetic appearance of the ceiling portion.
(3) In the invention according to claim 3, the same effects as those in (1) and (2) above can be obtained, and even when the left and right skeletons are greatly shaken by the earthquake and the joints are narrowed. The gentle slope of the upper surface of the joint plate causes the entire joint plate to rise upward, and the end plate can be easily rotated.

また、可動支持部材１３に設けられた係合片１７の底面には転動部材やすべり材（図示せず）を設けることが望ましく、この転動部材自体を脱落防止用の係合片１７としてもよい。 The movable support member 13 is connected to a central maintenance mechanism 16, and a substantially central portion thereof is always located at a substantially central portion in the left-right direction of the joint portion 2.
Further, it is desirable to provide a rolling member or a sliding member (not shown) on the bottom surface of the engaging piece 17 provided on the movable support member 13, and the rolling member itself is used as the engaging piece 17 for preventing falling off. May be good.

目地プレート７は、図５に示すように、平板状の目地プレート本体１８と、この目地プレート本体１８の左右端部にそれぞれヒンジ部材１９を介して接続された端板２０とで構成されている。この目地プレート７の底面には化粧板等のカバー板１１を設けることが望ましい。
なお、この目地プレート本体１８や端板２０、固定支持部材１２は、バー部材を枠状に形成した部材の上下面に板材を固定して形成してもよい。 As shown in FIG. 5, the joint plate 7 is composed of a flat joint plate main body 18 and end plates 20 connected to the left and right end portions of the joint plate main body 18 via hinge members 19, respectively. .. It is desirable to provide a cover plate 11 such as a decorative plate on the bottom surface of the joint plate 7.
The joint plate main body 18, the end plate 20, and the fixed support member 12 may be formed by fixing the plate material to the upper and lower surfaces of the member in which the bar member is formed in a frame shape.

実施形態の目地プレート本体１８の左右方向の略中央部には、前記目地プレート支持手段６の接続部材１４の下端部が固定されており、吊り下げ状態で目地プレート７が支持されている。 The lower end of the connecting member 14 of the joint plate supporting means 6 is fixed to a substantially central portion of the joint plate main body 18 in the left-right direction of the embodiment, and the joint plate 7 is supported in a suspended state.

ヒンジ部材１９はガイド手段５の上方に位置（ヒンジ部材１９の下方にカバー板１１が位置）しており、目地部２の下方からヒンジ部材１９や端板２０は目視できないように設けられている。このように配設することにより、美観を向上させることができる。
地震で一方と他方の躯体３、４が揺れ動き目地部２が狭くなると、図６に示すように、目地プレート７全体がガイド手段５の緩斜面９によって緩やかに上方にせり上がるとともに、その両端部の端板２０が傾斜面８により押圧されてヒンジ部材１９を支点に回動し、地震による揺れ動きを吸収する。 The hinge member 19 is located above the guide means 5 (the cover plate 11 is located below the hinge member 19), and the hinge member 19 and the end plate 20 are provided so as not to be visible from below the joint portion 2. .. By arranging in this way, the aesthetic appearance can be improved.
When one and the other skeletons 3 and 4 sway due to an earthquake and the joint portion 2 becomes narrower, as shown in FIG. 6, the entire joint plate 7 is gently raised upward by the gentle slope 9 of the guide means 5, and both ends thereof. The end plate 20 of the above is pressed by the inclined surface 8 and rotates around the hinge member 19 as a fulcrum to absorb the shaking motion due to the earthquake.

なお、端板２０が傾斜面８により押圧される際の衝撃を小さくするために、端板２０の端部を面取り加工する、端板２０の端部に滑動部材等を設ける等してもよい。 In addition, in order to reduce the impact when the end plate 20 is pressed by the inclined surface 8, the end portion of the end plate 20 may be chamfered, or a sliding member or the like may be provided at the end portion of the end plate 20. ..

更に目地部２が狭くなった場合には、図７に示すように、傾斜面８によって目地プレート７全体が上方へせり上がり、地震による揺れ動きを吸収する。このように目地プレート７全体が上方へせり上がる場合でも、予め端板２０は回動しており、この端板２０が略面接触状態で傾斜面８により押圧されるため衝撃が少なくなり、カバー板１１等が衝撃により損傷することを防止できる。 When the joint portion 2 is further narrowed, as shown in FIG. 7, the entire joint plate 7 is raised upward by the inclined surface 8 to absorb the shaking motion due to the earthquake. Even when the entire joint plate 7 is raised upward in this way, the end plate 20 is rotated in advance, and the end plate 20 is pressed by the inclined surface 8 in a substantially surface contact state, so that the impact is reduced and the cover is covered. It is possible to prevent the plate 11 and the like from being damaged by the impact.

Next, different modes for carrying out the present invention shown in FIGS. 9 to 14 will be described. In the description of these different embodiments for carrying out the present invention, the same components as those of the first embodiment for carrying out the present invention are designated by the same reference numerals, and duplicate description will be omitted.

図９乃至図１４に示す本発明を実施するための第２の形態において、前記本発明を実施するための第１の形態と主に異なる点は、パンタグラフ状のリンク部材２１と、このリンク部材２１の中央枢支部２２に取付けられた接続部材１４とで目地プレート支持手段６Ａを構成するとともに、緩斜面を有さず、傾斜面８と、この傾斜面８に連続するように略水平の平坦面２３が形成されたガイド部材１０Ａを用いたガイド手段５Ａを用いた点で、このような天井用目地装置１Ａにしても前記本発明を実施するための第１の形態と同様の作用効果を得ることができる。 In the second embodiment for carrying out the present invention shown in FIGS. 9 to 14, the main difference from the first embodiment for carrying out the present invention is the pantograph-shaped link member 21 and the link member. The joint plate supporting means 6A is composed of the connecting member 14 attached to the central pivot portion 22 of the 21. In that the guide means 5A using the guide member 10A on which the surface 23 is formed is used, even such a ceiling joint device 1A has the same effect as the first embodiment for carrying out the present invention. Obtainable.

本実施形骸においては、端板２０の端部（せり上がり側の自由端部）を傾斜面８の角度に対応するようなテーパー状に形成することが望ましい。 In the present embodiment, it is desirable to form the end portion (free end portion on the rising side) of the end plate 20 in a tapered shape corresponding to the angle of the inclined surface 8.

ところで、本実施形態においては、リンク部材２１が中央維持機構１６を兼ねている。
なお、目地プレート支持手段として支持部材を用いるものや、パンタグラフ状のリンク部材を用いるものについて説明したが、例えば伸縮アームを用いてこの伸縮アームと目地プレートを接続部材でせつぞくするものや、１対のラックとピニオンを用いてピニオンの中央部を目地部の中央部に位置させ、ラックピニオンに目地プレートを接続部材を介して接続する等、目地プレートを支持でき、かつ、接続部材を常時目地部の略中央部に位置させることができるものであればどのようなものでもよい。 By the way, in the present embodiment, the link member 21 also serves as the central maintenance mechanism 16.
In addition, although a support member is used as the joint plate supporting means and a pantograph-shaped link member is used, for example, a telescopic arm is used to connect the telescopic arm and the joint plate with a connecting member. A pair of racks and pinions can be used to position the central part of the pinion at the center of the joint, and the joint plate can be connected to the rack pinion via a connecting member, so that the joint plate can be supported and the connecting member is always connected. Anything that can be located substantially in the center of the joint may be used.
