Description

本発明は、多角形天井板の上に配設される、該天井板とほぼ同一面形状の天井ボードを保持するための天井板用押え機構に関するものである。   The present invention relates to a ceiling plate presser mechanism for holding a ceiling board that is disposed on a polygonal ceiling plate and has substantially the same surface shape as the ceiling plate.

例えば、図１８に示すように、天井板１は、格子状に組み付けられた天井板用吊持杆ｆに、一区画毎に多数整列状に支持されて、室内の天井を構成するものである。ここで、天井板用吊持杆ｆは、断面がほぼ逆Ｔ字状をなし、その下端に天井板１の側縁を支持する支持部ｇと、その上端にハンガーｊが固着される係止部ｉとを備え、格子状に組み付けられることで、天井板ｐの四辺を成す各側縁を各支持部ｇにより支持するようにした構成が一般的である（例えば、特許文献１）。   For example, as shown in FIG. 18, the ceiling board 1 is supported by the ceiling board suspension rods f assembled in a lattice shape so that a large number of the ceiling boards 1 are aligned in each section, thereby constituting an indoor ceiling. . Here, the ceiling plate suspension rod f has a substantially inverted T-shaped cross section, a support portion g for supporting the side edge of the ceiling plate 1 at its lower end, and a hanger j fixed to its upper end. Generally, a configuration is provided in which each side edge forming the four sides of the ceiling board p is supported by each support portion g by being provided with a portion i and assembled in a lattice shape (for example, Patent Document 1).

このような天井板の上には、断熱作用、防音作用、室内と天井板上の空間との空気の流通を妨げる作用（いわゆる気密性）等を備えた天井ボードが配される。この天井ボードとしては、一般的にグラスウール、岩綿板、石膏ボード等が用いられる。ここで、天井ボードが天井板上からズレてしまうと、該天井ボードの断熱作用や防音作用や気密性が低下する。そのため、天井板の側縁を上方に起立する形状とし、かつ天井ボードを天井板とほぼ同一面形状として、該天井ボードを天井板上に保持するようにしている。しかし、この構成は天井ボードを側方から支持するだけであるため、該天井ボードが上方へズレることを防止できず、天井板から天井ボードが浮いた状態ともなり得る。このため、例えば、天井ボードを、天井板の上面に接着したり、又は、その角部を針金等により固定することにより、該天井ボードが上方へズレることが無いように天井板上に保持している。
特開２００２−２８５６７５号公報（図１８参照） On such a ceiling board, a ceiling board having a heat insulating action, a soundproofing action, an action that hinders air flow between the room and the space above the ceiling board (so-called airtightness) and the like is arranged. As the ceiling board, glass wool, rock wool board, gypsum board or the like is generally used. Here, if the ceiling board is displaced from the ceiling board, the heat insulating effect, soundproofing effect and airtightness of the ceiling board are lowered. For this reason, the side edge of the ceiling board is formed so as to rise upward, and the ceiling board is formed in substantially the same plane shape as the ceiling board so that the ceiling board is held on the ceiling board. However, since this configuration only supports the ceiling board from the side, the ceiling board cannot be prevented from shifting upward, and the ceiling board may be in a state of floating from the ceiling board. For this reason, for example, by attaching the ceiling board to the upper surface of the ceiling board or fixing the corners with a wire or the like, the ceiling board is held on the ceiling board so that the ceiling board is not displaced upward. ing.
JP 2002-285675 A (see FIG. 18)

ところで、上述したように、天井ボードが上方へズレないように天井板上に保持するために、該天井ボードを天井板の上面に接着してしまうと、天井ボード又は天井板のいずれか一方が損傷等した場合でも、両者とも取り替えることを要する。さらに、取り付けを誤った場合にも修正することが難しいという問題もある。一方、天井板の上に天井ボードを配置して、その角部を針金等で固定することにより該天井ボードを保持するようにした構成にあっては、該針金を外すことにより、天井ボードと天井板とのいずれか一方のみを交換することも可能である。ここで、具体的には、天井板の角部の両側に孔を設け、この両側の孔間に針金を通して結び、該針金を締め付けることにより、天井板上に天井ボードを押え付けて上方から保持するようにしている。ところが、天井板上に天井ボードをしっかりと押え付けた状態で保持するために、針金を強く締め付けようとすると、該針金により天井ボードを傷つけ易い。また、針金の締付けが弱いと、天井ボードが天井板上で動き易くなり、さらに針金が緩むことともなってしまい、充分な保持作用を発揮できない。このように、針金を適正に締め付けることは難しく、作業者の技術に任せることとなり、天井ボードの保持状態を均一化することができない。また、この針金を締め付ける作業は、作業の繁雑化と作業時間の増加とを生ずることとなり、施工作業だけでなく、メンテナンス作業や取り替え作業時の作業効率も低下するという問題もある。   By the way, as described above, in order to hold the ceiling board on the ceiling plate so that the ceiling board does not shift upward, if the ceiling board is bonded to the upper surface of the ceiling plate, either the ceiling board or the ceiling plate is Even if they are damaged, both must be replaced. Furthermore, there is a problem that it is difficult to correct even if the attachment is wrong. On the other hand, in the configuration in which the ceiling board is disposed on the ceiling board and the corner portion is fixed with a wire or the like to hold the ceiling board, the ceiling board and the ceiling board are removed by removing the wire. It is also possible to replace only one of the ceiling boards. Here, specifically, holes are provided on both sides of the corner of the ceiling plate, a wire is passed between the holes on both sides, and the wire is tightened to hold the ceiling board on the ceiling plate and hold it from above. Like to do. However, in order to hold the ceiling board firmly pressed on the ceiling board, if the wire is tightened strongly, the ceiling board is easily damaged by the wire. Further, if the wire is weakly tightened, the ceiling board is easy to move on the ceiling plate, and the wire is also loosened, so that a sufficient holding action cannot be exhibited. In this way, it is difficult to properly tighten the wire, and it is left to the operator's technique, and the holding state of the ceiling board cannot be made uniform. In addition, the work of tightening the wire causes complicated work and an increase in work time, and there is a problem that work efficiency at the time of maintenance work and replacement work is lowered as well as construction work.

そこで、本発明は、天井ボードを天井板の上に適正に保持でき、かつ、天井ボードを保持するための作業と該保持を解消する作業とを効率的に行い得る天井板用押え機構を提供することを目的とする。   Therefore, the present invention provides a ceiling plate presser mechanism that can properly hold the ceiling board on the ceiling board and that can efficiently perform the work for holding the ceiling board and the work for eliminating the holding. The purpose is to do.

本発明は、多角形天井板の上に配設される、該天井板とほぼ同一面形状の天井ボードを保持するものであって、天井板の角部の両側に突成された係合孔を具備する係止縁部と、両端に係止縁部の係合孔に夫々に嵌入可能な杆状の嵌入突部が形成された押え部材とを備え、該押え部材を、その嵌入突部を各係合孔に嵌入して一対の係止縁部間に差し渡すことにより、天井板上の天井ボードの角部を上方から保持することを特徴とする天井板用押え機構である。   The present invention holds a ceiling board that is disposed on a polygonal ceiling board and has substantially the same surface shape as the ceiling board, and has an engagement hole formed on both sides of the corner of the ceiling board. And a pressing member formed with hook-like fitting protrusions that can be fitted into the engaging holes of the locking edge at both ends, respectively. The ceiling plate presser mechanism is characterized in that the corners of the ceiling board on the ceiling plate are held from above by being inserted into the respective engagement holes and passed between the pair of locking edges.

かかる構成にあっては、天井板上に天井ボードを配し、一対の係止縁部の各係合孔に、押え部材の嵌入突部を嵌入することにより、当該押え部材を係止縁部間に差し渡し、天井ボードが上方へ動くことを防ぎ、天井板上に保持することができるものである。ここで、押え部材は、その嵌入突部を係合孔に嵌入するという比較的容易な作業により、一対の係止縁部間に差し渡して取り付けることができ得る。したがって、天井ボードを天井板上に保持するための作業を簡素化できる。また、嵌入突部を係合孔から離脱させることにより、押え部材を係止縁部から比較的容易に取り外せるため、メンテナンス作業や天井ボード又は天井板の交換作業も容易に行い得る。尚、押え部材の取り付け及び取り外し作業時に、天井ボードが損傷することを防止することもできる。   In such a configuration, the ceiling board is disposed on the ceiling plate, and the presser member is fitted to the engaging edge portion by inserting the insertion protrusion of the presser member into each engaging hole of the pair of engaging edge portions. It can be passed between them to prevent the ceiling board from moving upward, and can be held on the ceiling board. Here, the pressing member can be attached between the pair of locking edges by a relatively easy operation of inserting the fitting protrusion into the engagement hole. Therefore, the work for holding the ceiling board on the ceiling board can be simplified. Further, by removing the fitting protrusion from the engagement hole, the pressing member can be removed from the engaging edge relatively easily, so that maintenance work and replacement work of the ceiling board or ceiling plate can be easily performed. In addition, it is possible to prevent the ceiling board from being damaged at the time of attaching and removing the pressing member.

このような天井板用押え機構にあって、押え部材は、線材から形成されてなり、天井板の両係止縁部の内側から各係合孔に嵌入する両端の嵌入突部と、各嵌入突部の内側に連成され、係止縁部に当接して嵌入突部が係合孔に嵌入した状態を保持する嵌合保持部と、嵌合保持部間に設けられ、一対の係止縁部間に差し渡された場合に、天井板上に配した天井ボードを上方から保持すると共に、前記嵌入突部を係止縁部の係合孔に係脱可能とする面押え部とを備えたものとする構成が提案される。   In such a ceiling plate presser mechanism, the presser member is formed of a wire rod, and the insertion protrusions at both ends are fitted into the respective engagement holes from the inside of the both locking edges of the ceiling plate, and the respective insertions A fitting holding portion that is coupled to the inside of the protrusion and holds the state where the fitting protrusion is in contact with the locking edge and is fitted in the engagement hole, and a pair of locking A surface presser that holds the ceiling board arranged on the ceiling plate from above when being passed between the edges, and that allows the fitting protrusion to be engaged with and disengaged from the engagement hole of the locking edge; A configuration to be provided is proposed.

かかる構成にあっては、押え部材が係止縁部間に取り付けられている場合に、嵌合保持部により、嵌入突部が係合孔に嵌入した状態で保持されることとなるから、非人為的な力により外れてしまうことを防止できる。したがって、面押え部により天井板上に天井ボードを保持した状態を堅持できる。ここで、嵌合保持部は、嵌入突部が係合孔から外れないための、いわゆるストッパの働きをするものである。さらに、押え部材は線材から形成されたものであるから、その面押え部を、両端の嵌入突部の間隔を狭くするように撓ませることも比較的容易である。このため、面押え部を撓ませた状態として、嵌入突部を係合孔に係脱する作業を容易に行うことができ得る。而して、押え部材の取り付け作業及び取り外し作業とを効率的に行うことができる。   In such a configuration, when the presser member is attached between the locking edges, the fitting holding portion holds the fitting protrusion in a state of being fitted into the engagement hole. It can be prevented from coming off by artificial force. Therefore, the state where the ceiling board is held on the ceiling board by the surface pressing portion can be firmly maintained. Here, the fitting holding portion functions as a so-called stopper so that the fitting protrusion does not come off the engaging hole. Furthermore, since the pressing member is formed of a wire rod, it is relatively easy to bend the surface pressing portion so as to narrow the interval between the fitting protrusions at both ends. For this reason, it is possible to easily perform the operation of engaging and disengaging the fitting protrusion with the engaging hole in a state where the surface pressing portion is bent. Thus, the attaching operation and the removing operation of the pressing member can be performed efficiently.

ここで、押え部材は、嵌合保持部を、両端の嵌入突部から天井板の側縁に沿って延びる杆部により構成すると共に、面押え部が、両側の嵌合保持部から連成され、板面方向で、内外方向へ屈曲形成されるＵ形屈曲部を備えるものであるとした構成も提案される。   Here, the presser member is configured such that the fitting holding portion includes a flange portion extending from the fitting protrusion at both ends along the side edge of the ceiling plate, and the surface pressing portion is coupled to the fitting holding portions on both sides. A configuration is also proposed in which a U-shaped bent portion that is bent inward and outward in the plate surface direction is provided.

かかる構成にあっては、面押え部を、天井板の側縁に沿って伸びる杆部と連成してＵ形屈曲部を形成してなるものとしたから、当該押え部材を係止縁部に取り付けた場合に、この面押え部は、角部の、係合孔に対して外側（角端側）と内側（角端と反対側）との両側で、天井ボードを上方から支持することとなる。したがって、この押え部材は、その両嵌入突部を支軸として傾動することがなく、天井ボードを安定的に保持できる。さらに、この面押え部は、天井ボードの角部の比較的広い領域を支持することとなり、これによっても天井ボードの保持作用が高まる。また、面押え部は、そのＵ形屈曲部により曲がりバネ作用を発揮し得ることから、両端の嵌入突部を互いの間隔を狭めるように弾性変形させることにより、該嵌入突部を係止縁部の内側から係合孔に容易に係脱することができ得る。したがって、押え部材の取り付け作業及び取り外し作業とを一層容易に行うことができ、この作業効率もさらに高まる。尚、本構成の面押え部にあっては、Ｕ形屈曲部を、内方へ屈曲形成されるものと、外方へ屈曲形成されるものとのいずれか一方を備えるようにしても、両方共備えるようにしても良い。   In this configuration, since the surface pressing portion is formed by forming a U-shaped bent portion coupled with the flange portion extending along the side edge of the ceiling plate, the pressing member is fixed to the locking edge portion. When this is attached to the surface, this face retainer shall support the ceiling board from above on both the outside (corner end side) and inside (opposite side of the corner end) of the corner. It becomes. Therefore, the pressing member can stably hold the ceiling board without tilting with the both insertion protrusions as the support shaft. Furthermore, the surface pressing portion supports a relatively wide area of the corner portion of the ceiling board, which also enhances the holding action of the ceiling board. Further, since the U-shaped bent portion of the surface pressing portion can exert a bending spring action, the fitting protrusions at the both ends are elastically deformed so as to narrow the interval between the fitting protrusions. The engagement hole can be easily engaged and disengaged from the inside of the portion. Therefore, the work for attaching and removing the pressing member can be performed more easily, and this work efficiency is further enhanced. In the surface pressing portion of this configuration, the U-shaped bent portion may be provided with either one that is bent inward or one that is bent outward. You may make it prepare together.

さらに、このようなＵ形屈曲部の、角端から板面に沿って延びる両側杆部に、上方へ突出するように湾曲する指操作部を備えている構成も提案される。この指操作部は、作業者が指を引っ掛ける等することにより、当該Ｕ形屈曲部による曲がりバネ作用を利用して、両端の嵌入突部を係合孔に係脱できるようにしたものである。したがって、当該押え部材を係止縁部に取り付ける作業と取り外す作業とを一層容易に行うことができる。   Further, a configuration is also proposed in which such a U-shaped bent portion is provided with a finger operation portion that curves so as to protrude upward on both side flanges extending from the corner end along the plate surface. This finger operation portion is configured such that when an operator hooks a finger or the like, the fitting protrusions at both ends can be engaged with and disengaged from the engagement holes using the bending spring action of the U-shaped bent portion. . Therefore, the work of attaching and removing the presser member to the locking edge can be performed more easily.

また、上述した押え部材は、面押え部を、両側の嵌合保持部間を直線形状としてなるものとする構成が提案される。かかる構成にあっても、面押え部を湾曲させるように撓ませることにより、両端の嵌入突部を係合孔に係脱でき、当該押え部材を係止縁部間に取り付ける作業と取り外す作業とを容易に行うことができ得る。また、面押え部を直線形状とすることにより、当該押え部材を低コストで製造できるという優れた利点もある。尚、本構成にあって、直線形状の面押え部を比較的長く形成するように、角端よりできるだけ内側に係止縁部を形成することにより、天井ボードの保持作用を高めることができ、好適な構成として用い得る。   In addition, a configuration is proposed in which the pressing member described above has a surface pressing portion having a linear shape between the fitting holding portions on both sides. Even in such a configuration, by bending the face pressing portion so as to be bent, the fitting protrusions at both ends can be engaged with and disengaged from the engaging hole, and the work for attaching and removing the pressing member between the locking edges Can be done easily. Moreover, there is also an excellent advantage that the pressing member can be manufactured at a low cost by forming the surface pressing portion in a linear shape. In addition, in this configuration, by forming the locking edge portion as far as possible from the corner end so as to form the linear surface pressing portion relatively long, the holding action of the ceiling board can be enhanced, It can be used as a suitable configuration.

さらにまた、上述した係止縁部の係合孔を、その側縁に沿うように横長状に形成し、面押え部に、板面方向で、係合孔よりも角端へ延出するように屈曲する屈曲部を形成し、かつ面押え部の両外側から内方へ延出する杆部に、前記係合孔に内方から嵌入する鈎状の嵌入突部を形成した構成も提案される。   Furthermore, the engagement hole of the locking edge described above is formed in a horizontally long shape along the side edge so that the surface pressing portion extends in the plate surface direction to the corner end from the engagement hole. In addition, a configuration is also proposed in which a bent portion that is bent inwardly is formed, and a hook-like fitting protrusion that is fitted into the engagement hole from the inside is formed on the flange portion that extends inwardly from both outer sides of the surface pressing portion. The

かかる構成にあっては、面押え部の両端から延びる杆部を、互いに内方へ変位させることにより、嵌入突部を内側から係合孔に容易に係脱することができる。ここで、本構成の押え部材は、天井板の内側から角端に向かってスライドさせることによっても、鈎状の嵌入突部を係合孔に嵌入させることができる。したがって、押え部材を係止縁部間に一層容易に取り付けることができ得る。また、角端へ延出する屈曲部が形成された面押え部と、内方へ延出する杆部とにより、天井ボードを保持するようになっていることから、当該押え部材は、傾動することもなく安定的に保持できると共に、角部の比較的広い領域で天井ボードを支持できるため、該天井ボードの保持作用に優れる。   In such a configuration, the fitting protrusions can be easily engaged with and disengaged from the engagement holes from the inside by displacing the flanges extending from both ends of the surface pressing portion inward. Here, the presser member of this configuration can also insert the hook-shaped insertion protrusion into the engagement hole by sliding from the inside of the ceiling plate toward the corner end. Therefore, the pressing member can be more easily attached between the locking edges. In addition, since the ceiling board is held by the face pressing portion formed with the bent portion extending to the corner end and the flange portion extending inward, the pressing member tilts. In addition, the ceiling board can be supported stably in a relatively wide area at the corners, and thus the ceiling board is excellent in holding action.

一方、上述した天井板用押え機構にあって、角部の両側に設けた係止縁部の角端と反対側で、該係止縁部に近接する位置に、その側縁に沿った支持溝が形成された支持縁部を突成してなり、押え部材は、線材から形成され、支持溝間に差し渡されて天井ボードを上方から保持する面押え部と、該面押え部の両端で、天井板の外側で屈曲して天井板の側縁に沿って角端側に延出する保持杆部と、該保持杆部の端縁を内方へ屈曲して形成される嵌入突部とを備えてなり、面押え部の端部を前記支持溝に係合し、嵌入突部を外側から係止縁部の係合孔に嵌入することにより、天井板上に配した天井ボードを上方から保持する状態に取り付けられる構成が提案される。又は、角部の両側に設けた係止縁部の角端側で、該係止縁部に近接する位置に、その側縁に沿った支持溝が形成された支持縁部を突成してなり、押え部材は、線材から形成され、支持溝間に差し渡されて天井ボードを上方から保持する面押え部と、該面押え部の両端で、天井板の外側で屈曲して天井板の側縁に沿って角端と反対側に延出する保持杆部と、該保持杆部の端縁を内方へ屈曲して形成される嵌入突部とを備えてなり、面押え部の端部を前記支持溝に係合し、嵌入突部を外側から係止縁部の係合孔に嵌入することにより、天井板上に配した天井ボードを上方から保持する状態に取り付けられる構成も提案される。   On the other hand, in the ceiling plate presser mechanism described above, on the opposite side of the corner edge of the locking edge provided on both sides of the corner, support along the side edge is provided at a position close to the locking edge. The holding member is formed by projecting a support edge portion in which a groove is formed, and the holding member is formed of a wire, and is sandwiched between the supporting grooves and holds the ceiling board from above, and both ends of the holding member And a holding hook part that is bent outside the ceiling board and extends to the corner end side along the side edge of the ceiling board, and a fitting protrusion formed by bending the edge of the holding hook part inwardly A ceiling board disposed on the ceiling plate by engaging the end portion of the surface pressing portion with the support groove and inserting the fitting protrusion into the engaging hole of the locking edge portion from the outside. A configuration is proposed that is mounted in a state of being held from above. Alternatively, at the corner end side of the locking edge provided on both sides of the corner, a support edge formed with a support groove along the side edge is formed at a position close to the locking edge. The holding member is formed of a wire rod, is sandwiched between the support grooves and is held between the support groove, and is bent at the both ends of the surface holding portion at the both ends of the ceiling plate to be A holding collar extending along the side edge to the opposite side of the corner end, and a fitting protrusion formed by bending the end edge of the holding collar inward, the end of the surface pressing part A configuration is also proposed in which the ceiling board placed on the ceiling board is held from above by engaging the support portion with the support groove and inserting the insertion protrusion into the engagement hole of the locking edge from the outside. Is done.

かかる両構成にあっては、支持縁部を、角縁の両側の、係止縁部に対して角端側又は反対側に設け、該支持縁部の支持溝と係止縁部の係合孔とにより押え部材を取り付けるようにしたものであるから、当該押え部材が非人為的な力により外れることを防止でき、この取り付け状態を長期にわたって堅持でき得る。したがって、天井ボードを天井板上に保持する作用も高い。ここで、押え部材は、面押え部と嵌入突部との間に形成された保持杆部により、該嵌入突部を係合孔に比較的容易に係脱することができる。したがって、押え部材の取り付け作業と取り外し作業とを効率的に行うことができる。尚、支持溝は、支持縁部の角端側に形成される構成と、角端と反対側に形成される構成とのいずれとすることもできる。   In both of these configurations, the support edge is provided on both sides of the corner edge on the corner end side or the opposite side with respect to the stop edge, and the support groove of the support edge is engaged with the stop edge. Since the presser member is attached by the hole, it is possible to prevent the presser member from coming off due to an inhuman force, and this attachment state can be maintained for a long time. Therefore, the effect | action which hold | maintains a ceiling board on a ceiling board is also high. Here, the holding member can be engaged and disengaged with respect to the engagement hole relatively easily by the holding collar formed between the surface pressing portion and the insertion protrusion. Therefore, the attaching operation and the removing operation of the pressing member can be performed efficiently. In addition, a support groove | channel can be made into any of the structure formed in the corner end side of a support edge part, and the structure formed in the opposite side to a corner end.

また、上述した天井板用押え機構にあって、押え部材は、天井板の角部の側縁に接する保持板縁を備えた板状の面押え板部を、上方に突出するＵ形湾曲突部の両側に夫々連成し、該保持板縁に天井板の係止縁部に形成された係合孔に嵌入する嵌入突部を夫々突設してなる構成が提案される。又は、押え部材は、天井板の角部の側縁に接する保持板縁を備えた板状の面押え板部を、板面方向で天井板の内方へ突出するＵ形湾曲突部の両側に夫々に連成し、該保持板縁に天井板の係止縁部に形成された係合孔に嵌入する嵌入突部を夫々突設してなる構成が提案される。   Further, in the ceiling plate pressing mechanism described above, the pressing member has a U-shaped curved protrusion that protrudes upward from a plate-shaped surface pressing plate portion having a holding plate edge in contact with a side edge of a corner portion of the ceiling plate. A configuration is proposed in which fitting protrusions are formed so as to be coupled to both sides of the portion, and to be fitted into engagement holes formed in the retaining edge of the ceiling plate on the holding plate edge. Alternatively, the presser member has a plate-like surface presser plate portion provided with a holding plate edge in contact with a side edge of the corner portion of the ceiling plate, on both sides of the U-shaped curved protrusions protruding inward of the ceiling plate in the plate surface direction. A configuration is proposed in which fitting protrusions are formed so as to be coupled to the holding plate edge and to be fitted into engagement holes formed in the locking edge portion of the ceiling plate.

かかる両構成にあっては、板状の面押え板部が、その板面により天井ボードを上方から面支持するようにしたものであるから、安定かつ高い保持作用を発揮できる。さらに、両側の面押え板部間に設けられたＵ形湾曲突部により、当該押え部材が両側の面押え板部の間隔を狭くするように弾性変形することができる。すなわち、このＵ形湾曲突部のバネ作用により、各面押え板部の保持板縁に突成された嵌入突部の間隔も狭くでき、両側の嵌入突部を係合孔に比較的容易に係脱できる。したがって、押え部材の取り付け作業と取り外し作業とを容易かつ効率的に行うことができる。尚、かかる構成の押え部材にあっては、一枚の板材を屈曲加工してなるものが好適に用いられる。   In both of these configurations, the plate-like surface pressing plate portion is such that the ceiling board is surface-supported from above by the plate surface, so that a stable and high holding action can be exhibited. Further, the U-shaped curved protrusions provided between the side surface pressing plate portions on both sides allow the pressing member to be elastically deformed so as to narrow the interval between the side surface pressing plate portions on both sides. That is, due to the spring action of the U-shaped curved protrusions, the interval between the insertion protrusions formed on the holding plate edge of each face pressing plate part can be narrowed, and the insertion protrusions on both sides can be made relatively easily into the engagement holes. Can be engaged and disengaged. Therefore, the pressing member attaching operation and removing operation can be performed easily and efficiently. In addition, in the pressing member having such a configuration, a member obtained by bending a single plate material is preferably used.

本発明の天井板用押え機構は、多角形天井板の上に配設される、該天井板とほぼ同一面形状の天井ボードを保持するものであって、天井板の角部の両側に突成された係合孔を具備する係止縁部と、両端に係止縁部の係合孔に夫々に嵌入可能な杆状の嵌入突部が形成された押え部材とを備え、該押え部材を、その嵌入突部を各係合孔に嵌入して一対の係止縁部間に差し渡すことにより、天井板上の天井ボードの角部を上方から保持するようにした構成であるから、嵌入突部を比較的容易に係合孔に係脱でき、天井ボードを天井板上に保持するための作業や、該保持状態を解消するための作業を容易かつ効率的に行うことができ得る。   The ceiling plate presser mechanism according to the present invention holds a ceiling board that is disposed on a polygonal ceiling plate and has substantially the same surface shape as the ceiling plate, and protrudes on both sides of the corner of the ceiling plate. A locking edge having a formed engaging hole, and a pressing member formed with hook-like fitting protrusions that can be fitted into the engaging holes of the locking edge at both ends, respectively. The corners of the ceiling board on the ceiling board are held from above by inserting the fitting protrusions into the respective engagement holes and passing between the pair of locking edges. The fitting protrusion can be engaged with and disengaged from the engaging hole relatively easily, and the work for holding the ceiling board on the ceiling plate and the work for eliminating the holding state can be easily and efficiently performed. .

上記した押え部材が、線材から形成されてなり、天井板の両係止縁部の内側から各係合孔に嵌入する両端の嵌入突部と、各嵌入突部の内側に連成され、係止縁部に当接して嵌入突部が係合孔に嵌入した状態を保持する嵌合保持部と、嵌合保持部間に設けられ、一対の係止縁部間に差し渡された場合に、天井板上に配した天井ボードを上方から保持すると共に、前記嵌入突部を係止縁部の係合孔に係脱可能とする面押え部とを備えた構成として場合にあっては、天井板上に天井ボードを保持した状態を堅持できる。また、線材からなる面押え部を撓ませることにより、嵌入突部を係合孔に容易に係脱でき、押え部材の取り付け作業及び取り外し作業とを効率的に行うことができる。   The above-mentioned presser member is formed of a wire rod, and is coupled to the fitting protrusions at both ends that are fitted into the respective engagement holes from the inside of the both locking edges of the ceiling plate, and the inside of each of the fitting protrusions. When it is provided between the fitting holding part and the fitting holding part, which is in contact with the stop edge part and holds the state where the fitting protrusion is fitted in the engaging hole, and passed between the pair of locking edge parts In addition, when holding the ceiling board arranged on the ceiling plate from above, and as a configuration comprising a surface pressing portion that allows the fitting protrusion to be engaged with and disengaged from the engagement hole of the locking edge, The state where the ceiling board is held on the ceiling board can be maintained. Further, by bending the surface pressing portion made of a wire, the fitting protrusion can be easily engaged with and disengaged from the engagement hole, and the pressing member can be attached and removed efficiently.

ここで、押え部材は、嵌合保持部を、両端の嵌入突部から天井板の側縁に沿って延びる杆部により構成すると共に、面押え部が、両側の嵌合保持部から連成され、板面方向で、内外方向へ屈曲形成されるＵ形屈曲部を備える構成とした場合にあっては、この面押え部が、傾動することなく天井ボードを安定的に保持できると共に、比較的広い領域を保持できるため、優れた保持作用を発揮できる。また、Ｕ形屈曲部を備えた面押え部の曲がりバネ作用により、当該押え部材の取り付け作業及び取り外し作業とを一層容易かつ効率的に行うことができ得る。   Here, the presser member is configured such that the fitting holding portion includes a flange portion extending from the fitting protrusion at both ends along the side edge of the ceiling plate, and the surface pressing portion is coupled to the fitting holding portions on both sides. In the case of a configuration having a U-shaped bent portion that is bent inward and outward in the plate surface direction, the surface pressing portion can stably hold the ceiling board without tilting, and relatively Since a wide area can be held, an excellent holding action can be exhibited. In addition, due to the bending spring action of the surface pressing portion provided with the U-shaped bent portion, the pressing member can be attached and removed more easily and efficiently.

また、このＵ形屈曲部の、角端から板面に沿って延びる両側杆部に、上方へ突出するように湾曲する指操作部を備えている構成とした場合にあっては、作業者がこの指操作部に指を引っ掛ける等して、容易に、当該押え部材を係止縁部に取り付けたり、取り外したりすることができ得る。   In addition, in the case where the U-shaped bent portion is configured to have finger operation portions that are curved so as to protrude upward on both side flanges extending from the corner ends along the plate surface, The pressing member can be easily attached to or detached from the engaging edge by hooking a finger on the finger operating portion.

また、上述した押え部材は、面押え部を、両側の嵌合保持部間を直線形状としてなる構成とした場合にあっては、面押え部を湾曲させるように撓ませることにより、当該押え部材を係止縁部間に取り付ける作業と取り外す作業とを容易に行うことができる。   Further, in the case where the above-described presser member has a configuration in which the surface presser portion is configured to have a linear shape between the fitting holding portions on both sides, the presser member is bent by bending the surface presser portion. It is possible to easily perform the work of attaching and removing between the locking edges.

また、上述した係止縁部の係合孔を、その側縁に沿うように横長状に形成し、面押え部に、板面方向で、係合孔よりも角端へ延出するように屈曲する屈曲部を形成し、かつ面押え部の両外側から内方へ延出する杆部に、前記係合孔に内方から嵌入する鈎状の嵌入突部を形成した構成にあっては、当該押え部材を、天井板の内側から角端に向かってスライドさせることにより、係止縁部間に取り付けることができる。また、面押え部と内方へ延出する杆部とにより、天井ボードを安定的に保持できる。   In addition, the engagement hole of the locking edge described above is formed in a horizontally long shape along the side edge so that the surface pressing portion extends in the plate surface direction to the corner end rather than the engagement hole. In a configuration in which a bent portion that bends to fit into the engagement hole from the inside is formed on the flange portion that forms a bent portion that is bent and extends inward from both outer sides of the surface pressing portion. By sliding the pressing member from the inside of the ceiling plate toward the corner end, it can be attached between the locking edges. Further, the ceiling board can be stably held by the face pressing portion and the flange portion extending inward.

一方、角部の両側に設けた係止縁部の角端と反対側で、該係止縁部に近接する位置に、その側縁に沿った支持溝が形成された支持縁部を突成してなり、押え部材は、線材から形成され、支持溝間に差し渡されて天井ボードを上方から保持する面押え部と、該面押え部の両端で、天井板の外側で屈曲して天井板の側縁に沿って角端側に延出する保持杆部と、該保持杆部の端縁を内方へ屈曲して形成される嵌入突部とを備えてなり、面押え部の端部を前記支持溝に係合し、嵌入突部を外側から係止縁部の係合孔に嵌入することにより、天井板上に配した天井ボードを上方から保持する状態に取り付けられる構成が提案される。又は、角部の両側に設けた係止縁部の角端側で、該係止縁部に近接する位置に、その側縁に沿った支持溝が形成された支持縁部を突成してなり、押え部材は、線材から形成され、支持溝間に差し渡されて天井ボードを上方から保持する面押え部と、該面押え部の両端で、天井板の外側で屈曲して天井板の側縁に沿って角端と反対側に延出する保持杆部と、該保持杆部の端縁を内方へ屈曲して形成される嵌入突部とを備えてなり、面押え部の端部を前記支持溝に係合し、嵌入突部を外側から係止縁部の係合孔に嵌入することにより、天井板上に配した天井ボードを上方から保持する状態に取り付けられる構成も提案される。かかる両構成にあっては、支持溝と係合孔とにより押え部材を嵌合することにより、当該押え部材が非人為的な力により外れることを防きぎ、この取り付け状態を長期にわたって堅持でき得る。また、押え部材は、その保持杆部により、該嵌入突部を係合孔に比較的容易に係脱することができるため、押え部材の取り付け作業と取り外し作業とを効率的に行うことができる。   On the other hand, on the opposite side of the corner edge of the locking edge provided on both sides of the corner, a support edge is formed with a support groove along the side edge at a position close to the locking edge. The presser member is formed of a wire rod, is passed between the support grooves and holds the ceiling board from above, and is bent at the both ends of the face presser part and bent outside the ceiling plate. A holding hook extending to the corner end along the side edge of the plate, and a fitting protrusion formed by bending the edge of the holding hook inward, and the end of the surface pressing portion A configuration is proposed in which the ceiling board placed on the ceiling board is held from above by engaging the part with the support groove and inserting the fitting protrusion into the engaging hole of the locking edge from the outside. Is done. Or, at the corner end side of the locking edge provided on both sides of the corner, a support edge formed with a support groove along the side edge is formed at a position close to the locking edge. The holding member is formed of a wire rod, is sandwiched between the support grooves and is held between the support groove, and is bent at the both ends of the surface holding portion at the both ends of the ceiling plate to be A holding collar extending along the side edge to the opposite side of the corner end, and a fitting protrusion formed by bending the end edge of the holding collar inward, the end of the surface pressing part A configuration is also proposed in which the ceiling board placed on the ceiling board is held from above by engaging the support portion with the support groove and inserting the insertion protrusion into the engagement hole of the locking edge from the outside. Is done. In both of these configurations, by fitting the presser member with the support groove and the engagement hole, it is possible to prevent the presser member from coming off due to an inhuman force, and this attachment state can be maintained for a long time. . Further, since the holding member can relatively easily engage and disengage the fitting protrusion with the engaging hole, the holding member can efficiently attach and remove the holding member. .

また、押え部材は、天井板の角部の側縁に接する保持板縁を備えた板状の面押え板部を、上方に突出するＵ形湾曲突部の両側に夫々連成し、該保持板縁に天井板の係止縁部に形成された係合孔に嵌入する嵌入突部を夫々突設してなる構成が提案される。又は、押え部材は、天井板の角部の側縁に接する保持板縁を備えた板状の面押え板部を、板面方向で天井板の内方へ突出するＵ形湾曲突部の両側に夫々に連成し、該保持板縁に天井板の係止縁部に形成された係合孔に嵌入する嵌入突部を夫々突設してなる構成も提案される。かかる両構成にあっては、面押え板部がその板面により天井ボードを天井板上に面支持し、安定かつ高い保持作用を発揮できるものである。さらに、Ｕ形湾曲突部のバネ作用により、押え部材の取り付け作業と取り外し作業とを容易かつ効率的に行うことができる。   In addition, the holding member is formed by coupling plate-like surface holding plate portions each having a holding plate edge in contact with the side edge of the corner portion of the ceiling plate on both sides of the U-shaped curved protruding portion protruding upward. A configuration is proposed in which insertion protrusions that are inserted into engagement holes formed in the locking edge portion of the ceiling plate are provided on the plate edge. Alternatively, the presser member has a plate-like surface presser plate portion provided with a holding plate edge in contact with a side edge of the corner portion of the ceiling plate, on both sides of the U-shaped curved protrusion that protrudes inward of the ceiling plate in the plate surface direction. A configuration is also proposed in which a fitting projection is formed so as to be coupled to each other and to be fitted into an engagement hole formed in the retaining edge of the ceiling plate. In both of these configurations, the surface pressing plate portion supports the ceiling board on the ceiling plate by the plate surface and can exhibit a stable and high holding action. Further, the attaching operation and the removing operation of the pressing member can be easily and efficiently performed by the spring action of the U-shaped curved protrusion.

添付図面に従って本発明の実施例を説明する。   Embodiments of the present invention will be described with reference to the accompanying drawings.

図１は、本発明にかかる天井板用押え機構により、四角形状の天井板１の上に、該天井板１とほぼ同一な四角面形状の天井ボード２が保持された状態を示すものである。ここで、天井板１の四辺である各側縁は、上方に起立する起立縁３として形成されている（図１（ロ））。そして、この起立縁３は、当該天井板１上に配される天井ボード２を側方から支持する役割を有している。さらに、この起立縁３には、上縁から天井板１の外側へ折曲して延出された支持側縁４が形成されている（図１（イ））。この支持側縁４は、天井ボード２を保持した天井板１を、格子状に組まれた該天井板用吊持杆ｆに配設される場合に、該天井板用吊持杆ｆの支持部ｇ上で支持され、当該天井板１を支えるものである（図１８参照）。尚、この支持側縁４は、天井板１の起立縁３の、後述する係止縁部１０，１０が突成される部位には形成されていない。また、この天井ボード２は、断熱性と防音性とを有するグラスウールからなるものを用いている。さらに、このグラスウールのパネル面に、アルミ箔等を接着して、充分な気密性を発揮できるようにしている。   FIG. 1 shows a state in which a rectangular ceiling board 2 that is substantially the same as the ceiling board 1 is held on a rectangular ceiling board 1 by the ceiling board pressing mechanism according to the present invention. . Here, each side edge which is four sides of the ceiling board 1 is formed as the standing edge 3 which stands up (FIG. 1 (B)). And this standing edge 3 has the role which supports the ceiling board 2 distribute | arranged on the said ceiling board 1 from the side. Further, the standing edge 3 is formed with a support side edge 4 which is bent and extended from the upper edge to the outside of the ceiling board 1 (FIG. 1 (A)). This support side edge 4 is used to support the ceiling plate suspension rod f when the ceiling plate 1 holding the ceiling board 2 is disposed on the ceiling plate suspension rod f assembled in a lattice shape. It is supported on the part g and supports the ceiling board 1 (see FIG. 18). In addition, this support side edge 4 is not formed in the site | part by which the locking edge part 10 and 10 mentioned later of the standing edge 3 of the ceiling board 1 protrude. Moreover, this ceiling board 2 uses what consists of glass wool which has heat insulation and sound insulation. Furthermore, an aluminum foil or the like is adhered to the glass wool panel surface so that sufficient airtightness can be exhibited.

この天井板１には、図１（ロ）に示すように、その角部５の両側の起立縁３から上方に突出する係止縁部１０，１０が形成されており、両側の係止縁部１０，１０には、互いに対向するように係合孔１１，１１が形成されている。この係合孔１１，１１は、起立縁３に沿って横長形状に孔開されてなるものとしている。ここで、天井ボード２に、板厚方向に圧縮変形可能なグラスウールを使用していることから、起立縁３が、その高さを該天井ボード２の板厚に比して僅かに低くなるように形成されていると共に、係止縁部１０，１０に設けられる係合孔１１，１１は、その孔下端の高さ位置が、天井板１上に配設された天井ボード２の上面位置に比して低い高さ位置となるように設けられている。尚、係止縁部１０，１０及び係合孔１１，１１は、それぞれ両側で、角端６から等距離となる位置に設けられている。   As shown in FIG. 1 (b), the ceiling plate 1 is formed with locking edge portions 10 and 10 protruding upward from the standing edges 3 on both sides of the corner portion 5, and the locking edges on both sides are formed. Engagement holes 11 and 11 are formed in the portions 10 and 10 so as to face each other. The engagement holes 11 are formed in a horizontally long shape along the standing edge 3. Here, since glass wool that can be compressed and deformed in the thickness direction is used for the ceiling board 2, the rising edge 3 is slightly lower in height than the thickness of the ceiling board 2. In addition, the engaging holes 11 and 11 provided in the locking edge portions 10 and 10 are arranged such that the height position of the lower end of the hole is the upper surface position of the ceiling board 2 disposed on the ceiling board 1. It is provided so as to be at a lower height position. The locking edge portions 10 and 10 and the engagement holes 11 and 11 are provided at positions that are equidistant from the corner end 6 on both sides.

また、本実施例１の天井板用押え機構は、図１のように、上記した天井板１に形成した係止縁部１０，１０と、該係止縁部１０，１０間に差し渡される押え部材１５とから構成される。この押え部材１５は、金属製の線材を屈曲加工することにより、板面方向で、角部５を両側に略二分割する対角線に対して略対称形状に形成されてなる。押え部材１５の両端には、係止縁部１０，１０の係合孔１１，１１に嵌入する嵌入突部１６，１６が、一直線上となるように形成されている。そして、この嵌入突部１６，１６から角端６方向に屈曲し、起立縁３に沿って延びる杆部１８，１８が形成されている。ここで、この杆部１８，１８により、係止縁部１０，１０の内面に当接して該嵌入突部１６，１６を係合孔１１，１１に嵌入した状態に保持する嵌合保持部１７，１７が構成されている。さらに、この杆部１８，１８には、その内縁から天井板１の内方へ屈曲する連成杆部２２、２２が連成されており、この間に、該内方へ突出するように略Ｕ形状に屈曲形成されたＵ形屈曲部１９が連成されている。ここで、この連成杆部２２，２２及びＵ形屈曲部１９とが、本発明の面押え部２０である。尚、この押え部材１５は、Ｕ形屈曲部１９から両端の嵌入突部１６，１６まで、同一面上となるように形成されている。   Further, the ceiling plate pressing mechanism of the first embodiment is passed between the locking edge portions 10 and 10 formed on the ceiling plate 1 and the locking edge portions 10 and 10 as shown in FIG. The presser member 15 is configured. The holding member 15 is formed in a substantially symmetric shape with respect to a diagonal line that substantially bisects the corner portion 5 on both sides in the plate surface direction by bending a metal wire. At both ends of the pressing member 15, insertion protrusions 16 and 16 that are inserted into the engagement holes 11 and 11 of the locking edge portions 10 and 10 are formed so as to be in a straight line. Then, flanges 18 and 18 that are bent from the fitting protrusions 16 and 16 toward the corner end 6 and extend along the standing edge 3 are formed. Here, the fitting holding part 17 that abuts the inner surface of the locking edge part 10, 10 and holds the fitting protrusions 16, 16 in the engagement holes 11, 11 by the flange parts 18, 18. , 17 are configured. Further, the flange portions 18 and 18 are coupled with coupled flange portions 22 and 22 that are bent inwardly from the inner edge of the ceiling plate 1, and in the meantime, substantially U so as to protrude inwardly. A U-shaped bent portion 19 bent in a shape is coupled. Here, the coupled saddle portions 22 and 22 and the U-shaped bent portion 19 are the surface pressing portion 20 of the present invention. The pressing member 15 is formed so as to be on the same plane from the U-shaped bent portion 19 to the fitting protrusions 16 and 16 at both ends.

このような押え部材１５を、図２に示すように、天井板１の係止縁部１０，１０間に取り付ける。天井板１の上に、天井ボード２を配置した後、押え部材１５を、両端の嵌入突部１６，１６の間隔を狭めるように弾性変形させ（図３（イ））、該嵌入突部１６，１６を両側の係止縁部１０，１０の係合孔１１，１１に夫々に嵌入する（図３（ロ））。この時、押え部材１５を、その弾性変形を開放して復元することにより、嵌合保持部１７，１７が係止縁部１０，１０の内面に当接し、嵌入突部１６，１６と係合孔１１，１１との嵌合状態が保持される。尚、ここで、両端の嵌入突部１６，１６は、係止得部１０，１０に対して斜め方向に変位するため、横長形状の係合孔１１，１１に比較的容易に嵌入できることとなっている。   Such a pressing member 15 is attached between the locking edge portions 10 of the ceiling board 1 as shown in FIG. After the ceiling board 2 is arranged on the ceiling board 1, the holding member 15 is elastically deformed so as to narrow the interval between the insertion protrusions 16 and 16 at both ends (FIG. 3 (A)). , 16 are inserted into the engaging holes 11, 11 of the locking edge portions 10, 10 on both sides (FIG. 3 (b)). At this time, the holding member 15 is restored by releasing its elastic deformation, so that the fitting holding portions 17, 17 abut against the inner surfaces of the locking edge portions 10, 10 and engage with the fitting protrusions 16, 16. The fitting state with the holes 11 and 11 is maintained. In addition, since the insertion protrusions 16 and 16 at both ends are displaced in an oblique direction with respect to the locking portions 10 and 10, the insertion protrusions 16 and 16 at the both ends can be relatively easily inserted into the horizontally long engagement holes 11 and 11. ing.

こうして、押え部材１５は、係止縁部１０，１０間に差し渡されるように取り付けられる。そして、押え部材１５は、嵌合保持部１７、１７間の、連成杆部２２及びＵ形屈曲部１９からなる面押え部２０により、天井板１の上に配された断面パネル２を上方から保持する。ここで、係合孔１１，１１は、上述したように、その孔下端が、天井ボード２の上面位置より低くなるように設けていることから、面押え部２０により、該天井ボード２は上方から押さえつけられた状態で保持されることとなる。また、面押え部２０は、板面方向に形成されていることから、該断面パネル２の角部を比較的広い領域で保持できるようになっている。さらにまた、この面押え部２０は、両側の係止縁部１０，１０より角端６側と内側（角端６と反対側）との両側で天井ボードを保持するように配設されることから、当該押え部材１５が、両端の嵌合保持部１７，１７を支点として傾動することもなく、天井ボード２を安定的に保持することができる。   In this way, the pressing member 15 is attached so as to be passed between the locking edges 10 and 10. Then, the holding member 15 moves the cross-sectional panel 2 arranged on the ceiling plate 1 upward by means of the surface holding portion 20 including the coupling rod portion 22 and the U-shaped bent portion 19 between the fitting holding portions 17 and 17. Hold from. Here, since the engagement holes 11 and 11 are provided so that the lower ends of the holes are lower than the upper surface position of the ceiling board 2 as described above, the ceiling board 2 is moved upward by the surface pressing portion 20. It will be held in a pressed state. Further, since the surface pressing portion 20 is formed in the plate surface direction, the corner portion of the cross-sectional panel 2 can be held in a relatively wide area. Furthermore, the surface pressing portion 20 is disposed so as to hold the ceiling board on both sides of the corner edge 6 side and the inner side (opposite side of the corner edge 6) than the locking edge portions 10, 10 on both sides. Therefore, the pressing member 15 can stably hold the ceiling board 2 without tilting with the fitting holding portions 17 and 17 at both ends as fulcrums.

一方、天井ボード２と天井板１とを分離する場合には、押え部材１５を、両端の嵌入突部１６，１６の間隔を狭めるように弾性変形させ、係合孔１１，１１から嵌入突部１６，１６を離脱させることにより、係止縁部１０，１０から取り外す。これにより、天井ボード２の保持状態を解消できる。   On the other hand, when the ceiling board 2 and the ceiling plate 1 are separated, the holding member 15 is elastically deformed so as to narrow the interval between the insertion protrusions 16 and 16 at both ends, and the insertion protrusions from the engagement holes 11 and 11. 16 and 16 are detached from the locking edges 10 and 10 by releasing them. Thereby, the holding state of the ceiling board 2 can be eliminated.

このような実施例１の天井板用押え機構にあっては、押え部材１５を係止縁部１０，１０間に差し渡すように取り付けることにより、該押え部材１５が係止縁部１０，１０間に固持され、天井板１上に配した天井ボード２を上方から保持できる。このため、天井ボード２を配した天井板１は、格子状に組まれた天井板吊持杆ｆに配設されて室内の天井を構成した場合に、該天井ボード２が天井板１からズレることもなく、本来の断熱性を充分に発揮できる。さらに、この押え部材１５は、その面押え部２０の形態による曲がりバネ作用により、両端の嵌入突部１１，１１を係止縁部１０，１０の係合孔１１，１１に嵌入又は離脱することを容易に行い得る。したがって、天井ボード２を保持する作業や、天井板１と分離する作業を簡素化でき、これら作業効率を向上でき得る。さらには、この押え部材１５の取り付け作業及び取り外し作業時に、天井ボード２を損傷してしまうことも防止できる。   In the ceiling plate pressing mechanism of the first embodiment, the pressing member 15 is attached so as to pass between the locking edges 10 and 10, so that the pressing member 15 is locked to the locking edges 10 and 10. It is possible to hold the ceiling board 2 held on the ceiling board 1 from above from above. For this reason, the ceiling board 1 provided with the ceiling board 2 is displaced from the ceiling board 1 when the ceiling board 1 is arranged on a ceiling board suspension rod f assembled in a lattice shape to constitute an indoor ceiling. Without any problem, the original heat insulating property can be sufficiently exhibited. Further, the presser member 15 is configured such that the insertion protrusions 11, 11 at both ends are inserted into or removed from the engagement holes 11, 11 of the locking edge portions 10, 10 by the bending spring action in the form of the surface presser 20. Can be easily performed. Therefore, the operation | work which hold | maintains the ceiling board 2 and the operation | work isolate | separated from the ceiling board 1 can be simplified, and these work efficiency can be improved. Furthermore, it is possible to prevent the ceiling board 2 from being damaged during the attaching operation and the removing operation of the pressing member 15.

ところで、上述した実施例１の押え部材にあって、図３に示すように、指操作部１４を設けるようにした構成とすることもできる。かかる構成の押え部材１５ａは、面押え部２０ａを構成するＵ形屈曲部１９ａの、角端６から天井板１の内方に向かって板面に沿って延びる両側杆部２１ａ，２１ａに、上方へ突出するように湾曲する指操作部１４を形成してなるものである。この指操作部１４は、作業者が指等で持ち易く、また、指を引っ掛けることにより、当該押え部材１５ａを係止縁部１０，１０に取り付けたり取り外したりする作業を一層容易に行うことができる。   By the way, in the presser member according to the first embodiment described above, the finger operation unit 14 may be provided as shown in FIG. The presser member 15a having such a configuration is formed on the U-shaped bent portion 19a constituting the surface presser portion 20a, on both side flange portions 21a and 21a extending along the plate surface from the corner end 6 toward the inner side of the ceiling plate 1. The finger operation part 14 which curves so that it may protrude is formed. The finger operation unit 14 can be easily held by a worker with a finger or the like, and can be more easily performed by attaching or removing the presser member 15a to or from the locking edge portions 10 and 10 by hooking the finger. it can.

また、上述した実施例１の押え部材にあって、図４（イ）に示すように、両端の嵌入突部１６ｂ，１６ｂを、嵌合保持部１７，１７から略直角に屈曲してなるものとする構成とすることもできる。かかる構成の押え部材１５ｂにあっては、天井板１の起立縁３に沿って延成される杆部１８，１８により構成される嵌合保持部１７，１７の両端から、該起立縁３に略直交するように外方へ屈曲されてなる、嵌入突部１６ｂ，１６ｂが形成されている。さらに、天井板１の起立縁３から上方に突成された係止縁部１０ｂ，１０ｂには、略円形の係合孔１１ｂ、１１ｂが形成されている（図４（ロ）参照）。そして、押え部材１５ｂは、両端の嵌入突部１６ｂ，１６ｂが係合孔１１ｂ，１１ｂに嵌入されて、係止縁部１０ｂ，１０ｂ間に差し渡されて取り付けられる。   Further, in the pressing member of the first embodiment described above, as shown in FIG. 4 (a), the fitting protrusions 16b, 16b at both ends are bent from the fitting holding parts 17, 17 at a substantially right angle. It can also be set as the structure. In the holding member 15b having such a configuration, the rising edge 3 is connected to both ends of the fitting holding parts 17 and 17 formed by the flange parts 18 and 18 extending along the rising edge 3 of the ceiling board 1. Insertion protrusions 16b and 16b are formed that are bent outward so as to be substantially orthogonal. Furthermore, substantially circular engagement holes 11b and 11b are formed in the locking edge portions 10b and 10b protruding upward from the standing edge 3 of the ceiling board 1 (see FIG. 4B). The presser member 15b is attached by fitting the fitting protrusions 16b, 16b at both ends into the engagement holes 11b, 11b and passing between the locking edges 10b, 10b.

実施例２の天井板用押え機構として、図５に示される構成が提案される。尚、上述した実施例１と共通する部分には同じ符号を付して説明を省略する。   The structure shown in FIG. 5 is proposed as the ceiling plate pressing mechanism of the second embodiment. In addition, the same code | symbol is attached | subjected to the part which is common in Example 1 mentioned above, and description is abbreviate | omitted.

実施例３の天井板用押え機構として、図６に示される構成が提案される。尚、上述した実施例１と共通する部分には同じ符号を付して説明を省略する。   A configuration shown in FIG. 6 is proposed as the ceiling plate pressing mechanism of the third embodiment. In addition, the same code | symbol is attached | subjected to the part which is common in Example 1 mentioned above, and description is abbreviate | omitted.

ここで、天井板１には、図６（ロ）のように、上述した実施例１と同様の係止縁部１０，１０が形成され、該係止縁部１０，１０には、横長形状の係合孔１１，１１が形成されている。尚、実施例３の係止縁部１０，１０は、実施例１に比して、角端６から離れた位置に設けている。   Here, as shown in FIG. 6B, the ceiling plate 1 is formed with locking edges 10 and 10 similar to those of the first embodiment, and the locking edges 10 and 10 have a horizontally long shape. Engagement holes 11 and 11 are formed. Note that the locking edge portions 10 of the third embodiment are provided at positions away from the corner end 6 as compared with the first embodiment.

また、押え部材３５は、図６（イ）のように、金属製の線材を略直線形状に形成してなり、両端に嵌入突部３６，３６が形成されている。この嵌入突部３６，３６の内側に、略板面方向に膨らむ扁平形状に形成した嵌合保持部３７，３７が連成されている。この嵌合保持部３７，３７が、係止縁部１０，１０の内面の、係合孔１１，１１の孔縁部分に当接することにより、嵌入突部３６，３６と係合孔１１，１１との嵌合状態を保持するようになっている。さらに、嵌合保持部３７，３７間が略直線形状の面押え部３９となっている。   Further, as shown in FIG. 6 (a), the pressing member 35 is formed by forming a metal wire in a substantially linear shape, and has fitting protrusions 36, 36 formed at both ends. Inside the fitting projections 36, 36, fitting holding portions 37, 37 formed in a flat shape that swells substantially in the plate surface direction are coupled.

Even in the surface holding portion 39 having a substantially linear shape, the ceiling board 2 can be appropriately held so as to be pressed onto the ceiling board 1 from above. Since the holding member 35 is formed by forming a wire in a straight line shape, this manufacturing is easy, and there is an excellent advantage that it can be manufactured at low cost.

このような実施例３にあって、押え部材の嵌合保持部を異なる形状とすることもできる。例えば、図７のように、押え部材３５ａの嵌合保持部３７ａ，３７ａを、互いに同一面方向に突出する湾曲形状とする。この嵌合保持部３７ａ，３７ａが、係止縁部１０，１０の内面の、係合孔１１，１１の孔縁部分に当接することにより、嵌入突部３６，３６と係合孔１１，１１との嵌合状態を保持するようになっている。また、この嵌合保持部３７ａ，３７ａは、その両端の嵌入突部３６，３６を支点として傾動することができるため、板面方向に対して上方に傾いた状態とすれば、ここに作業者が指等を引っ掛けて、当該押え部材３５ａの取り付け及び取り外し作業を一層容易に行うこともできる。この場合、この嵌合保持部３７ａ，３７ａは指操作部となる。また、この嵌合保持部３７ａ，３７ａを板面方向に沿った状態とすることにより、天井ボード２の保持作用を高めることもでき得る。   In the third embodiment, the fitting holding portion of the pressing member can have a different shape. For example, as shown in FIG. 7, the fitting holding portions 37 a and 37 a of the pressing member 35 a have curved shapes that protrude in the same plane direction. The fitting holding portions 37a and 37a come into contact with the hole edge portions of the engagement holes 11 and 11 on the inner surfaces of the locking edge portions 10 and 10, so that the fitting protrusions 36 and 36 and the engagement holes 11 and 11 are contacted. The fitting state is maintained. In addition, since the fitting holding portions 37a and 37a can be tilted with the fitting projections 36 and 36 at both ends thereof as fulcrums, if the worker is inclined upward with respect to the plate surface direction, the worker is here. By hooking a finger or the like, the attaching and detaching work of the pressing member 35a can be performed more easily. In this case, the fitting holding portions 37a and 37a serve as finger operation portions. Moreover, the holding | maintenance effect | action of the ceiling board 2 can also be improved by making this fitting holding | maintenance part 37a and 37a into the state along a plate | board surface direction.

さらに別の構成として、押え部材の、直線形状の面押え部にＵ形屈曲部を形成した構成とすることもできる。例えば、図８のように、押え部材３５ｂは、両端の嵌入突部３６，３６から、角端６側へ湾曲する形状の嵌合保持部３７ｂ，３７ｂを連成し、該嵌合保持部３７ｂ，３７ｂ間に形成されている直線状の面押え部３９ｂに、内方へ突出するＵ形屈曲部４２が連成されてなる。この押え部材３５ｂは、Ｕ形屈曲部４２の曲がりバネ作用により、嵌入突部３６，３６を係合孔１１，１１に嵌入し易くなっている。また、Ｕ形屈曲部４２により、天井ボード２の保持作用が向上する。   As another configuration, a U-shaped bent portion may be formed on the linear surface pressing portion of the pressing member. For example, as shown in FIG. 8, the pressing member 35 b includes fitting holding portions 37 b and 37 b that are curved toward the corner end 6 side from the fitting protrusions 36 and 36 at both ends, and the fitting holding portion 37 b , 37b, a U-shaped bent portion 42 protruding inward is coupled to a linear surface pressing portion 39b. This presser member 35 b is easy to fit the fitting protrusions 36, 36 into the engagement holes 11, 11 by the bending spring action of the U-shaped bent portion 42. Moreover, the holding | maintenance effect | action of the ceiling board 2 improves by the U-shaped bending part 42. FIG.

また、押え部材４５は、図９（イ）のように、面押え部４９が、板面方向で、係合孔５１，５１よりも角端へ突出するように屈曲形成された屈曲部５２と、該屈曲部５２の両端縁から両側の起立縁３，３に向かって延成された連成杆部５３，５３とにより構成されている。さらに、この連成杆部５３，５３の両端から、起立縁３，３に沿って角端６と反対方向に延びる杆部４８，４８が連成されている。そして、この杆部４８，４８の外側端から天井板１の内方へ延出する延出杆部５４，５４が設けられており、この延出杆部５４，５４の内側部位に、係合孔５１，５１に嵌入する鈎状の嵌入突部４６，４６が設けられている。ここで、嵌入突部４６，４６は、板面方向で、係止縁部５０，５０に対して、角端方向に傾斜し、反対側で略直交する鈎形状となるように屈曲形成されている。また、当該押え部材４５は、前記した起立縁３，３に沿った杆部４８，４８と嵌入突部４６，４６の外側縁部位とにより、係止縁部５０，５０に当接し、これら当接する部位により本発明にかかる嵌合保持部４７，４７が構成されている。尚、本実施例４の押え部材４５も、金属製の線材から形成されており、板面方向で、天井板１の対角線に対して略線対称となる構成となっている。   Further, as shown in FIG. 9 (A), the pressing member 45 includes a bent portion 52 formed by bending so that the surface pressing portion 49 protrudes to the corner end from the engagement holes 51, 51 in the plate surface direction. The bent portion 52 is composed of coupled flange portions 53 and 53 extending from both end edges toward the rising edges 3 and 3 on both sides. Further, flanges 48, 48 extending in the opposite direction to the corner end 6 along the standing edges 3, 3 are coupled from both ends of the coupled flanges 53, 53. And the extended eaves part 54 and 54 extended inward of the ceiling board 1 from the outer end of this eaves part 48 and 48 is provided, and it engages with the inner site | part of this extended eave part 54 and 54. The hook-shaped insertion protrusions 46 and 46 which are inserted into the holes 51 and 51 are provided. Here, the insertion protrusions 46 and 46 are bent and formed in the plate surface direction so as to have a hook shape that is inclined in the corner end direction with respect to the locking edge portions 50 and 50 and substantially orthogonal to the opposite side.

Further, the pressing member 45 abuts against the locking edge portions 50 and 50 by the flange portions 48 and 48 along the standing edges 3 and 3 and the outer edge portion of the fitting projections 46 and 46, and The fitting holding parts 47 and 47 concerning this invention are comprised by the site | part which contact | connects. In addition, the pressing member 45 of the fourth embodiment is also formed of a metal wire, and is configured to be substantially line symmetric with respect to the diagonal line of the ceiling board 1 in the plate surface direction.

この押え部材４５は、天井板１上に天井ボード２を配した後に、両側の延出杆部５４，５４の端縁を内方へ変位させ、両側の嵌入突部４６，４６を係合孔５１，５１に嵌入することにより、係止縁部５０，５０間に差し渡されて取り付けられる。又は、押え部材４５を、図１０のように、天井ボード２上を、天井板１の内側から角端６方向にスライドさせることによっても、該係止縁部５０，５０間に取り付けることができる。すなわち、押え部材４５を、その屈曲部５２を角端６方向を向くようにして、天井ボード２上に置き、角端６に向けてスライドさせる。このスライドによって、押え部材４５は、その鈎状の嵌入突部４６，４６が係止縁部５０，５０に接触すると、内方へ押圧されるととなり、該嵌入突部４６，４６間を狭めるように弾性変形する。そして、嵌入突部４６，４６が係止孔５１，５１に達すると、この弾性変形が開放されて該係合孔５１，５１に嵌入し、当該押え部材４５が係止縁部５０，５０に取り付けられる。一方、この押え部材４５を取り外す場合にあっては、延出杆部５４，５４の端縁を内方へ押し込むことにより、係合孔５１，５１から嵌入突部４６，４６を離脱させる。尚、この押え部材４５は、鈎状の嵌入突部４６，４６が係合孔５１，５１に嵌入していることから、角端６と反対方向へスライドして取り外すことはできない。   After the ceiling board 2 is arranged on the ceiling board 1, the pressing member 45 displaces the end edges of the extended flange parts 54, 54 inwardly, and causes the fitting protrusions 46, 46 on both sides to engage with the engagement holes. By being fitted into 51 and 51, it is passed between the locking edges 50 and 50 and attached. Alternatively, as shown in FIG. 10, the pressing member 45 can also be attached between the locking edges 50, 50 by sliding the ceiling board 2 on the ceiling board 2 from the inside of the ceiling board 1 toward the corner end 6. . That is, the pressing member 45 is placed on the ceiling board 2 with its bent portion 52 facing the corner end 6 direction, and is slid toward the corner end 6. By this sliding, the presser member 45 is pressed inward when the hook-shaped fitting projections 46 and 46 come into contact with the locking edge portions 50 and 50, thereby narrowing the gap between the fitting projections 46 and 46. It is elastically deformed. When the fitting projections 46 and 46 reach the locking holes 51 and 51, the elastic deformation is released and the fitting protrusions 46 and 46 are fitted into the engaging holes 51 and 51, and the pressing member 45 is engaged with the locking edges 50 and 50. It is attached. On the other hand, when the pressing member 45 is removed, the fitting protrusions 46 and 46 are disengaged from the engagement holes 51 and 51 by pushing the end edges of the extended flange portions 54 and 54 inward. Note that the presser member 45 cannot be removed by sliding in the opposite direction to the corner end 6 because the hook-like insertion protrusions 46 and 46 are fitted in the engagement holes 51 and 51.

The pressing member 55 is formed into a shape obtained by bending a metal wire and bending it in the plate surface direction.

本実施例５の天井板用押え機構にあっては、天井板１上に天井ボード２を配した後に、押え部材５５を、図１２のように、その面押え部５９の両端縁を支持溝６３，６３に係合し、嵌入突部５６，５６を外側から係合孔６１，６１に嵌入することにより、取り付けられる。すなわち、図１２（イ）のように、押え部材５５を、両端の嵌入突部５６，５６を面押え部５９に対して上方となるように傾けた状態で、面押え部５９の両端縁を支持縁部６２，６２の支持溝６３，６３に挿入する。その後、この面押え部５９を支軸として、両端の嵌入突部５６，５６を下方へ傾動させる。そして、図１２（ロ）のように、両端の嵌入突部５６，５６を、保持杆部５７，５７の屈曲部位の曲がりバネ作用により、外方へ拡げて、外側から係合孔６１，６１に嵌入する。このように押え部材５５は、面押え部５９の両端縁が支持溝６３，６３に係合され、嵌入突部５６，５６が係合孔６１，６１に嵌合されて、天井ボード２を上方から保持する状態で堅持されることとなり得る。   In the ceiling plate pressing mechanism of the fifth embodiment, after the ceiling board 2 is arranged on the ceiling plate 1, the pressing member 55 is connected to the both ends of the surface pressing portion 59 as shown in FIG. It engages with 63,63, and it attaches by inserting the insertion protrusions 56 and 56 in the engagement holes 61 and 61 from the outside. That is, as shown in FIG. 12 (a), the presser member 55 is tilted so that the fitting protrusions 56, 56 at both ends are upward with respect to the presser foot 59. It inserts in the support grooves 63 and 63 of the support edge parts 62 and 62. Thereafter, the fitting protrusions 56, 56 at both ends are tilted downward with the surface pressing portion 59 as a support shaft. Then, as shown in FIG. 12 (b), the fitting protrusions 56, 56 at both ends are expanded outward by the bending spring action of the bent portions of the holding hooks 57, 57, and the engagement holes 61, 61 are formed from the outside.

一方、この押え部材５５を取り外す場合には、両端の嵌入突部５６，５６を外方へ拡げて係合孔６１，６１から離脱させた後、面押え部５９を支持溝６３，６３から離脱させる。   On the other hand, when removing the presser member 55, the fitting protrusions 56, 56 at both ends are expanded outward and detached from the engagement holes 61, 61, and then the face retainer 59 is detached from the support grooves 63, 63. Let

このように本実施例５の天井板用押え機構にあっては、比較的容易かつ適正に、押え部材５５の取り付け作業及び取り外し作業を行うことができ、高い作業効率を発揮し得るものである。また、押え部材５５を、天井ボード２の保持状態で堅持できることから、非人為的な力により該天井ボード２がズレることもなく、比較的長期にわたって安定して保持することができる。したがって、上述した実施例１と同様、押え部材４５の取り付け及び取り外し作業の作業効率に優れると共に、天井ボード２の保持作用も高く、該天井ボード２の断熱性を充分に発揮できるという効果を奏する。   As described above, in the ceiling plate pressing mechanism according to the fifth embodiment, the pressing member 55 can be attached and removed relatively easily and appropriately, and high working efficiency can be exhibited. . Further, since the presser member 55 can be firmly held while the ceiling board 2 is being held, the ceiling board 2 can be held stably for a relatively long period of time without being displaced by an inhuman force. Therefore, as in the first embodiment described above, the work efficiency of attaching and detaching the pressing member 45 is excellent, and the holding action of the ceiling board 2 is high, and the heat insulating property of the ceiling board 2 can be sufficiently exhibited. .

実施例６の天井板用押え機構として、図１３に示される構成が提案される。この実施例６の構成は、上述した実施例５の構成と異なり、支持縁部を係止縁部の角端側に配設し、これに応じて押え部材を変えたものである。尚、上述した実施例５と共通する部分には同じ符号を付して説明を省略する。   The structure shown in FIG. 13 is proposed as the ceiling plate pressing mechanism of the sixth embodiment. The configuration of the sixth embodiment is different from the configuration of the fifth embodiment described above in that the support edge portion is disposed on the corner end side of the locking edge portion, and the pressing member is changed accordingly. In addition, the same code | symbol is attached | subjected to the part which is common in Example 5 mentioned above, and description is abbreviate | omitted.

天井板１には、図１３（ロ）のように、角部５の両側の起立縁３，３に、略円形の係合孔６１，６１が形成された係止縁部６０，６０が突成されており、該係止縁部６０，６０の角端６側に、支持溝６３，６３が形成された支持縁部６２，６２が突成されている。尚、係止縁部６０，６０と支持縁部６２，６２とは、夫々に近接し、かつ、角部５の両側で、それぞれが角端６から等距離となる位置に設けられている。   As shown in FIG. 13 (b), the ceiling plate 1 has locking edge portions 60, 60 in which substantially circular engaging holes 61, 61 are formed on the rising edges 3, 3 on both sides of the corner portion 5. The support edge portions 62 and 62 in which support grooves 63 and 63 are formed are formed on the corner end 6 side of the locking edge portions 60 and 60. Note that the locking edge portions 60 and 60 and the support edge portions 62 and 62 are provided close to each other and at the same distance from the corner end 6 on both sides of the corner portion 5.

また、押え部材６５は、図１３（イ）のように、略直線形状に形成され、その両端縁で支持溝６３，６３に係合される面押え部６９を備え、該面押え部６９の両端に連成され、天井板１の外側で屈曲して起立縁３に沿って角端６と反対側に延成された保持杆部６７，６７を備えている。さらに、この保持杆部６７，６７の端縁を天井板１の内方へ略直角に屈曲して、嵌入突部６６，６６が形成されている。尚、この押え部材６５は、金属製の線材を屈曲加工し、板面方向で屈曲されてなる形状に形成されている。   Further, as shown in FIG. 13A, the pressing member 65 includes a surface pressing portion 69 that is formed in a substantially linear shape and is engaged with the support grooves 63 and 63 at both ends of the pressing member 65. Holding hooks 67 and 67 which are coupled to both ends, bend outside the ceiling plate 1 and extend to the opposite side of the corner edge 6 along the standing edge 3 are provided. Further, the fitting protrusions 66 and 66 are formed by bending the end edges of the holding hooks 67 and 67 inwardly of the ceiling board 1 at a substantially right angle. The pressing member 65 is formed into a shape obtained by bending a metal wire and bending it in the plate surface direction.

この本実施例６の天井板用押え機構にあっても、上述した実施例５と同様に、押え部材６５を取り付け及び取り外しすることができる。すなわち、天井板１上に天井ボード２を配した後に、押え部材６５を、両端の嵌入突部６６，６６を面押え部５９に対して上方となるように傾け、面押え部６９の両端縁を支持溝６３，６３に挿入する。そして、この面押え部６９を支軸として、両端の嵌入突部６６，６６を下方へ傾動させ、該嵌入突部５６，５６を外方へ拡げて、外側から係合孔６１，６１に嵌入する。こうして、押え部材６５は、天井ボード２を上方から保持する状態で堅持されることとなり得る。このような本実施例６の構成にあっても、上述した実施例５と同様の作用効果を発揮することができ得る。   Even in the ceiling plate pressing mechanism of the sixth embodiment, the pressing member 65 can be attached and detached as in the fifth embodiment. That is, after the ceiling board 2 is arranged on the ceiling board 1, the holding member 65 is tilted so that the fitting protrusions 66, 66 at both ends are upward with respect to the face pressing portion 59, and both edges of the surface pressing portion 69 are arranged. Is inserted into the support grooves 63, 63. Then, with the surface pressing portion 69 as a support shaft, the fitting projections 66 and 66 at both ends are tilted downward, the fitting projections 56 and 56 are expanded outward, and are fitted into the engagement holes 61 and 61 from the outside. To do. In this way, the pressing member 65 can be held firmly while holding the ceiling board 2 from above. Even in this configuration of the sixth embodiment, the same operational effects as those of the fifth embodiment described above can be exhibited.

このような実施例６にあって、押え部材を、一方の保持杆部だけを上方へ傾斜する形状とする構成とすることもできる。例えば、図１４のように、押え部材６５ａは、一方の保持杆部６７ａが、面押え部６９の両端から角端６と反対側へ屈曲すると共に、上方へ傾斜するように形成されてなるものである。すなわち、この押え部材６５ａは、同一平面上に形成されていない。この押え部材６５ａを取り付ける場合には、面押え部６９及び保持杆部６７を天井ボード２の上面に沿って、該保持杆部６７の嵌入突部６６を外側から係合孔６１に嵌入するようにスライドさせ、面押え部６９の両端縁を支持溝６３，６３に挿入する。この時、保持杆部６７ａは上方に傾斜しており、該保持杆部６７ａから連成する嵌入突部６６ａは、係合孔１１の上方に位置する（図１４（ロ））。その後、この保持杆部６７ａを外側へ拡げつつ（図１４（イ））、下方へ傾動させて（図１４（ロ））、嵌入突部６６ａを係合孔１１に外側から嵌入する。このように、押え部材６５ａは、一方の保持杆部６７ａを下方へ傾動する弾性変形と、外側へ拡げる曲がりバネ作用とにより、係止縁部６０，６０間に差し渡すように取り付けることができる。かかる構成によっても、上述した実施例５と同様に、取り付け及び取り外し作業の作業効率に優れると共に、天井ボード２の保持作用も高く、該天井ボード２の断熱性を充分に発揮できるという効果を奏する。   In such a sixth embodiment, the pressing member may be configured to have a shape in which only one holding collar portion is inclined upward. For example, as shown in FIG. 14, the holding member 65a is formed such that one holding hook portion 67a is bent from both ends of the surface holding portion 69 to the opposite side to the corner end 6 and is inclined upward. It is. That is, the pressing member 65a is not formed on the same plane. When attaching the pressing member 65a, the surface pressing portion 69 and the holding hook 67 are fitted along the upper surface of the ceiling board 2, and the fitting protrusion 66 of the holding hook 67 is inserted into the engagement hole 61 from the outside. And both end edges of the surface pressing portion 69 are inserted into the support grooves 63, 63. At this time, the holding hook portion 67a is inclined upward, and the fitting protrusion 66a continuous from the holding hook portion 67a is located above the engagement hole 11 (FIG. 14 (B)). Thereafter, the holding collar 67a is expanded outward (FIG. 14 (a)) and tilted downward (FIG. 14 (b)), and the fitting protrusion 66a is fitted into the engagement hole 11 from the outside. In this manner, the pressing member 65a can be attached so as to pass between the locking edge portions 60 and 60 by the elastic deformation that tilts one holding hook portion 67a downward and the bending spring action that expands outward. . Even with such a configuration, as in the fifth embodiment described above, the work efficiency of the attachment and detachment work is excellent, and the action of holding the ceiling board 2 is high, and the heat insulating property of the ceiling board 2 can be sufficiently exhibited. .

実施例７の天井板用押え機構として、図１５、図１６に示される構成が提案される。尚、上述した実施例１と共通する部分には同じ符号を付して説明を省略する。   The structure shown in FIGS. 15 and 16 is proposed as the ceiling plate pressing mechanism of the seventh embodiment. In addition, the same code | symbol is attached | subjected to the part which is common in Example 1 mentioned above, and description is abbreviate | omitted.

天井板１には、図１６（ロ）のように、角部５の両側に、起立縁３に沿って長方形状とした係合孔７１，７１を形成した係止縁部７０，７０が、該起立縁３，３から突成されている。この係止縁部７０，７０及び係合孔７１，７１は、それぞれ両側で、角端６から等距離となる位置に設けられている。尚、係合孔７１，７１は、その孔下辺が、天井板１上に配設された天井ボード２の上面位置に比して低い高さ位置となるように、形成されている。これにより、後述する押え部材７５は、その面押え板部７４，７４により、該天井ボード２を上方から押さえつけるようにして保持する。   As shown in FIG. 16 (b), the ceiling plate 1 has locking edges 70, 70 formed with engaging holes 71, 71 having a rectangular shape along the standing edge 3 on both sides of the corner 5. It protrudes from the upright edges 3 and 3. The locking edge portions 70 and 70 and the engagement holes 71 and 71 are provided at positions that are equidistant from the corner end 6 on both sides. The engagement holes 71 and 71 are formed so that the lower sides of the holes are at a lower height than the position of the upper surface of the ceiling board 2 disposed on the ceiling board 1. As a result, the pressing member 75 described later holds the ceiling board 2 by pressing the ceiling board 2 from above by the surface pressing plate portions 74 and 74.

押え部材７５は、図１５のように、一枚の金属製板材を屈曲加工することにより形成されてなり、天井板１の角部５の起立縁３に沿った保持板縁７７，７７を備えた面押え板部７４，７４を、上方に突出するＵ形湾曲突部７３の両側の側腕部７２，７２に夫々連成し、各保持板縁７７，７７に係合孔７１，７１に嵌入する嵌入突部７６，７６を夫々突設してなるものである。ここで、両側の面押え板部７４，７４は、板面方向に沿って形成され、当該押え部材７５が取り付けられた場合に、その板面で面支持し押さえつけて保持できるようになっている。   As shown in FIG. 15, the pressing member 75 is formed by bending a single metal plate, and includes holding plate edges 77 and 77 along the standing edges 3 of the corners 5 of the ceiling plate 1. The surface pressing plate portions 74 and 74 are coupled to the side arm portions 72 and 72 on both sides of the U-shaped curved protruding portion 73 protruding upward, and the holding plate edges 77 and 77 are formed in the engagement holes 71 and 71, respectively. Insertion protrusions 76 and 76 to be inserted are respectively provided. Here, the surface pressing plate portions 74, 74 on both sides are formed along the plate surface direction, and when the pressing member 75 is attached, the surface pressing is supported and pressed by the plate surface. .

このような押え部材７５を、天井ボード２を天井板１上に配した後、天井板１の係止縁部７０，７０間に取り付ける（図１６）。押え部材７５のＵ形湾曲突部７３を、その両側の側腕部７２，７２間を狭くするように内方へ弾性変形させることにより、両側の面押え板部７４，７４の嵌入突部７６，７６の間隔を狭くする。この状態で、両側の係合孔７１，７１に嵌入突部７６，７６を嵌入するようにして、Ｕ形湾曲突部７３を復元させる。これにより、嵌入突部７６，７６と係合孔７１，７１とが嵌合され、かつ、各面押え板部７４，７４の保持板縁７７，７７が係止縁部７０，７０の内面に当接し、この嵌合状態を保持する。ここで、Ｕ形湾曲突部７３は、板バネとして働くようになっている。このように、押え部材７５が係止縁部７０，７０間に差し渡されるようにして取り付けることにより、天井板１上に配された天井ボード２を、押え部材７５の面押え板部７４，７４により上方から面支持する。これにより、天井ボード２を、天井板１上に保持した状態で堅持できる。   After the ceiling board 2 is arranged on the ceiling board 1, such a pressing member 75 is attached between the locking edges 70 and 70 of the ceiling board 1 (FIG. 16). The U-shaped curved projection 73 of the pressing member 75 is elastically deformed inward so as to narrow the space between the side arm portions 72, 72 on both sides thereof, thereby fitting the protrusions 76 on the surface pressing plate portions 74, 74 on both sides. , 76 is narrowed. In this state, the U-shaped curved projection 73 is restored by fitting the fitting projections 76 and 76 into the engagement holes 71 and 71 on both sides. As a result, the fitting protrusions 76 and 76 and the engagement holes 71 and 71 are fitted, and the holding plate edges 77 and 77 of the surface pressing plate portions 74 and 74 are formed on the inner surfaces of the locking edge portions 70 and 70. It abuts and maintains this fitting state. Here, the U-shaped curved protrusion 73 works as a leaf spring. In this way, by attaching the presser member 75 so as to pass between the locking edge portions 70, 70, the ceiling board 2 disposed on the ceiling plate 1 is attached to the surface presser plate portion 74, the presser member 75. The surface is supported by 74 from above. Thereby, the ceiling board 2 can be firmly held in a state of being held on the ceiling board 1.

一方、押え部材７５を取り外す場合には、Ｕ形湾曲突部７３を内方へ弾性変形させて、両側の嵌入突部７６，７６の間隔を狭め、係合孔７１，７１から離脱させる。   On the other hand, when the pressing member 75 is removed, the U-shaped curved projection 73 is elastically deformed inward to narrow the interval between the fitting projections 76 on both sides and is detached from the engagement holes 71 and 71.

このように本実施例７の天井板用押え機構にあっては、押え部材７５のＵ形湾曲突部７３の板バネ作用により、当該押え部材７５を取り付ける作業と取り外す作業とを、比較的容易かつ適正に行うことができる。すなわち、天井ボード２を天井板１上に保持する作業と、保持状態を解消する作業との作業効率が向上する。また、押え部材７５は、面押え板部７４，７４により天井ボード２を面支持していることから、該天井ボード２の保持状態を安定的に堅持でき、天井ボード２がズレることもない。したがって、上述した実施例１と同様、押え部材４５の取り付け及び取り外し作業の作業効率に優れると共に、天井ボード２の保持作用も高く、該天井ボード２の断熱性を充分に発揮できるという効果を奏する。   As described above, in the ceiling plate pressing mechanism of the seventh embodiment, it is relatively easy to attach and remove the pressing member 75 by the leaf spring action of the U-shaped curved protrusion 73 of the pressing member 75. And it can be done properly. That is, the work efficiency of the work of holding the ceiling board 2 on the ceiling board 1 and the work of eliminating the held state is improved. Further, since the pressing member 75 supports the ceiling board 2 by the surface pressing plate portions 74 and 74, the holding state of the ceiling board 2 can be stably held, and the ceiling board 2 is not displaced. Therefore, as in the first embodiment described above, the work efficiency of attaching and detaching the pressing member 45 is excellent, and the holding action of the ceiling board 2 is high, and the heat insulating property of the ceiling board 2 can be sufficiently exhibited. .

実施例８の天井板用押え機構として、図１７に示される構成が提案される。この実施例８の構成は、上述した実施例７の構成に対して、Ｕ形湾曲突部を異なる形状としたものである。尚、上述した実施例７と共通する部分には同じ符号を付して説明を省略する。   A configuration shown in FIG. 17 is proposed as the ceiling plate pressing mechanism of the eighth embodiment. In the configuration of the eighth embodiment, the U-shaped curved protrusion is different from the configuration of the seventh embodiment described above. In addition, the same code | symbol is attached | subjected to the part which is common in Example 7 mentioned above, and description is abbreviate | omitted.

この実施例８にあっては、天井板１を、上述の実施例７と同様の係止縁部７０，７０が形成されているものを用いている。   In the eighth embodiment, the ceiling plate 1 is used in which the locking edge portions 70, 70 similar to those in the seventh embodiment are formed.

The U-shaped curved projection 83 of the pressing member 85 is elastically deformed inward so as to narrow the space between the side arm portions 82 on both sides. Thereby, the space | interval of the insertion protrusions 86 and 86 of both sides is narrowed. In this state, the U-shaped curved projection 83 is restored by fitting the fitting projections 86 and 86 into the engagement holes 71 and 71 on both sides. As a result, the fitting protrusions 86 and 86 are engaged with the engagement holes 71 and 71, and the holding plate edges 87 and 87 of the surface pressing plate portions 84 and 84 are formed on the inner surfaces of the locking edge portions 70 and 70.
