Description

本発明は、吊り天井の構造に関する。   The present invention relates to a suspended ceiling structure.

従来、例えば学校、病院、生産施設、体育館、プール、空港ターミナルビル、オフィスビル、劇場、シネコン等の建物の天井として、吊り天井が多用されている(例えば、特許文献1、特許文献2参照)。そして、吊り天井(吊り天井構造)Aには、例えば図6に示すように、水平の一方向T1に所定の間隔をあけて並設される複数の野縁1と、野縁1に直交し、水平の他方向T2に所定の間隔をあけて並設され、複数の野縁1に一体に接続して設けられる複数の野縁受け2と、下端を野縁受け2に接続し、上端を上階の床材等の上部構造(建物躯体)3に固着して配設される複数の吊りボルト(吊り部材)4と、野縁1と野縁受け2からなる格子状の天井下地7(野縁1の下面)にビス留めして一体に取り付けられ、天井面(天井部5)を形成する石膏ボードなどの天井パネル(天井材)6とを備えて構成したものがある。   Conventionally, suspended ceilings are frequently used as ceilings of buildings such as schools, hospitals, production facilities, gymnasiums, pools, airport terminal buildings, office buildings, theaters, cinecones, etc. (see, for example, Patent Document 1 and Patent Document 2). . The suspended ceiling (suspended ceiling structure) A has a plurality of field edges 1 arranged in parallel at a predetermined interval in one horizontal direction T1, and is orthogonal to the field edges 1, for example, as shown in FIG. , A plurality of field receivers 2 that are provided in parallel in the other direction T2 in the horizontal direction and are integrally connected to a plurality of field edges 1, a lower end is connected to the field receiver 2, and an upper end is A plurality of suspension bolts (suspending members) 4 fixedly disposed on an upper structure (building frame) 3 such as a flooring material on the upper floor, and a grid-like ceiling base 7 including a field edge 1 and a field edge receiver 2 ( There are some which are provided with a ceiling panel (ceiling material) 6 such as a gypsum board which is integrally attached by screwing to the lower surface of the field edge 1 and forms a ceiling surface (ceiling part 5).

また、例えば図7に示すように、クリーンルームのようにファンフィルターユニット等の大重量の設備機器を天井部5に設置する必要がある吊り天井(吊り天井構造)Aには、水平の一方向T1に所定の間隔をあけて並設され、一方向T1に直交する他方向T2に延びる複数のTバー(断面逆T型の支持部材)8と、上端を上部構造に固着し、下端側をTバー8に接続して配設された複数の吊りボルト(吊り部材)4と、Tバー8などからなる天井下地7にビス留めして一体に取り付けられて天井面(天井部5)を形成する天井パネル(天井材)6とを備えて構成したものもある。   For example, as shown in FIG. 7, a suspended ceiling (suspended ceiling structure) A in which a heavy equipment such as a fan filter unit needs to be installed on the ceiling 5 as in a clean room has a horizontal direction T1. A plurality of T bars (supporting members having a reverse T-shaped cross section) 8 which are arranged in parallel with each other at a predetermined interval and extend in the other direction T2 orthogonal to one direction T1, and the upper end is fixed to the upper structure, and the lower end side is set to T A plurality of suspension bolts (suspension members) 4 connected to the bar 8 and a ceiling base 7 made of a T bar 8 or the like are screwed together to form a ceiling surface (ceiling portion 5). There is also a configuration including a ceiling panel (ceiling material) 6.

ここで、このように野縁1及び野縁受け2や、Tバー8等の天井下地7と天井パネル6を吊りボルト4で吊り下げ支持してなる吊り天井Aは、その構造上、地震時に作用する水平力によって横揺れしやすい。そして、地震時に横揺れして、天井部5の端部5aが壁や柱、梁などの建物構成部材(建物躯体)9に衝突し、天井パネル6に破損が生じたり、脱落が生じるおそれがあった。   Here, the suspended ceiling A formed by supporting the ceiling edge 7 and the ceiling panel 6 such as the field edge 1 and the field edge receiver 2 and the T-bar 8 with the suspension bolt 4 in this way is structurally resistant to an earthquake. It is easy to roll due to the acting horizontal force. Then, when the earthquake sways, the end portion 5a of the ceiling portion 5 may collide with a building component (building frame) 9 such as a wall, a column, or a beam, and the ceiling panel 6 may be damaged or fallen off. there were.

このため、従来、上部構造3などに上端側を接続し、下端側を吊りボルト4や、野縁1、野縁受け2、Tバー8などの天井下地7に接続して補強ブレース10を設け、天井下地7及び天井パネル6からなる天井部5の地震時の横揺れを抑えるようにしている(図7参照)。   For this reason, a reinforcing brace 10 is conventionally provided by connecting the upper end side to the upper structure 3 and the like, and connecting the lower end side to the ceiling base 7 such as the suspension bolt 4, the field edge 1, the field edge receiver 2, and the T-bar 8. In addition, the rolling of the ceiling portion 5 composed of the ceiling base 7 and the ceiling panel 6 is suppressed during an earthquake (see FIG. 7).

一方、補強ブレース10による耐震補強、耐震改修を行う際には、天井裏空間Hに作業員が入って取付作業を行うことが必要になる。このため、天井裏空間Hに配設された配線、配管、エアコン等の付帯設備などによって、補強できる範囲に制限が生じ、十分に対応できないケースがある。また、天井下地7などにJIS材ではない低強度の一般材が使用され、補強後の性能が不安定で十分な改修精度を確保できないケースや、点付け溶接部などがあることで対応できないケースもある。   On the other hand, when performing seismic reinforcement and seismic retrofit by the reinforcing brace 10, it is necessary for an operator to enter the ceiling space H and perform installation work. For this reason, there is a case in which the range that can be reinforced is limited by wiring, piping, an air conditioner, or the like arranged in the ceiling space H, and cannot be adequately handled. In addition, low-strength general materials that are not JIS materials are used for the ceiling base 7, etc., and the performance after reinforcement is unstable and sufficient repair accuracy cannot be ensured, or because there are spot welds etc. There is also.

一方、石膏ボードなどの天井パネル(天井材)6は低剛性材料(脆性材料)であるため、天井下地が高剛性になるほど、また補強ブレースを設けて高剛性にするほど、地震時に、天井パネル、特に天井パネルを天井下地に固着する天井パネルのビス周りに応力が集中し、この部分が脆性破壊して天井パネルの破損ひいては脱落が生じるおそれがあった。   On the other hand, since the ceiling panel (ceiling material) 6 such as gypsum board is a low-rigidity material (brittle material), the ceiling panel becomes more rigid in the earthquake as the ceiling foundation becomes more rigid or the reinforcement brace is made more rigid. In particular, stress is concentrated around the screws of the ceiling panel that fixes the ceiling panel to the ceiling base, and this portion may be brittlely broken to cause breakage of the ceiling panel and dropout.

また、天井パネルをぶどう棚鉄骨に直貼りしたり、天井パネルの天井面にネットを取り付け、天井パネルの脱落を防止する対策も存在するが、これらの対策においては、例えば劇場や大会議室、展示施設などの天井高さが高い場合、天井面積が非常に大きな場合、天井が複雑な形状である場合に、その適用が困難になったり、外観を損なうおそれがあり、また、維持管理の点でも問題がある。さらにビス周りなどの局部的な破損、すなわち破片の脱落に対応できないおそれがある。   In addition, there are measures to directly attach the ceiling panel to the grape shelf steel frame or attach a net to the ceiling surface of the ceiling panel to prevent the ceiling panel from falling off, but in these measures, for example, theaters and large conference rooms, When the ceiling height of exhibition facilities, etc. is high, the ceiling area is very large, or the ceiling has a complicated shape, its application may be difficult or the appearance may be impaired. But there is a problem. Furthermore, local damage such as around the screw, that is, there is a risk that it may not be able to cope with the falling off of fragments.

本発明は、上記事情に鑑み、地震時に天井材(天井パネル)の破損や脱落が生じることを防止しつつ、小片等の脱落をも確実に防止することを可能にし、補強と改修を同時に行うことが可能な吊り天井構造を提供することを目的とする。   In view of the above circumstances, the present invention makes it possible to surely prevent the falling off of small pieces and the like while preventing the breakage and dropping of the ceiling material (ceiling panel) during an earthquake, and simultaneously performing reinforcement and repair.

本実施形態の吊り天井(吊り天井構造)Bは、図1及び図2に示すように、野縁1と野縁受け2と吊り部材(吊りボルト)4と天井材6とを備えて構成されている。   The suspended ceiling (suspended ceiling structure) B of the present embodiment is configured to include a field edge 1, a field edge receiver 2, a suspension member (suspension bolt) 4, and a ceiling material 6, as shown in FIGS. ing.

野縁1は、例えば断面コ字状に形成された溝形鋼であり、水平に延設され、且つ水平の一方向の横方向T1に所定の間隔をあけ、平行に複数配設されている。   The field edge 1 is, for example, a grooved steel having a U-shaped cross section, and extends horizontally, and is arranged in parallel at a predetermined interval in a horizontal direction T1 in one horizontal direction. .

野縁受け2は、例えば断面コ字状に形成された溝形鋼であり、水平に延設され、且つ水平の他方向の横方向T2に所定の間隔をあけ、平行に複数配設されている。また、このとき、野縁受け2は、野縁1と交差するように配設されるとともに、複数の野縁1上に載置した状態で配設される。そして、各野縁受け2は、野縁1と交差する部分で、野縁接続用金具(クリップ)12を使用することにより野縁1に接続されている。   The field edge receiver 2 is, for example, a grooved steel having a U-shaped cross section, is horizontally extended, and is arranged in parallel with a predetermined interval in the horizontal direction T2 in the other horizontal direction. Yes. At this time, the field edge receiver 2 is disposed so as to intersect the field edge 1 and is disposed in a state of being placed on the plurality of field edges 1. Each field edge receiver 2 is connected to the field edge 1 by using a field edge connection fitting (clip) 12 at a portion intersecting the field edge 1.

吊り部材4は、円柱棒状に形成されるとともに外周面に雄ネジの螺刻を有する吊りボルトであり、上端を上階の床材等の上部構造3(建物躯体)に固着、または鋼製の根太等に緊結して垂下され、下端側を、吊り部材接続用金具(ハンガー)13を用いることにより野縁受け2に接続して複数配設されている。また、複数の吊り部材4は、所定の間隔をあけて分散配置されている。   The suspension member 4 is a suspension bolt that is formed in a cylindrical bar shape and has an external thread threaded on its outer peripheral surface, and its upper end is fixed to an upper structure 3 (building frame) such as an upper floor or is made of steel. A plurality of lower ends are connected and connected to the field edge receiver 2 by using a hanging member connecting metal fitting (hanger) 13. Further, the plurality of suspension members 4 are dispersedly arranged at a predetermined interval.

天井材(天井パネル)6は、2枚のボードを貼り付けて一体に積層形成したものであり、例えば天井付帯設備等の重量と併せて、1mあたり20kg程度の重量で形成されている。そして、この天井材6は、複数の野縁1の下面にビス留めなどして設置されている。なお、天井材6は、1枚および3枚以上のボードで構成されていてもよい。 The ceiling material (ceiling panel) 6 is formed by laminating two boards and integrally stacking them. For example, the ceiling material (ceiling panel) 6 is formed with a weight of about 20 kg per 1 m 2 together with the weight of a ceiling accessory. The ceiling material 6 is installed on the lower surfaces of the plurality of field edges 1 by screws or the like. The ceiling material 6 may be composed of one board and three or more boards.

そして、この吊り天井Bでは、吊り部材4を介して建物の上部構造3に、野縁1と野縁受け2と天井材6とが吊り下げ支持されている。また、野縁1と野縁受け2によって天井下地7が形成され、この天井下地7と天井下地7に取り付けた天井材6によって天井部5、この天井部5によって下階の天井面がそれぞれ形成されている。   In the suspended ceiling B, the field edge 1, the field edge receiver 2, and the ceiling material 6 are suspended and supported by the upper structure 3 of the building via the suspension member 4. Further, the ceiling base 7 is formed by the field edge 1 and the field edge receiver 2, and the ceiling part 5 is formed by the ceiling base 7 and the ceiling material 6 attached to the ceiling base 7, and the ceiling surface of the lower floor is formed by the ceiling part 5, respectively. Has been.

一方、本実施形態の吊り天井Bにおいては、天井材6の天井面に脱落防止部材15が接着剤を用いて一体に貼設されている。この脱落防止部材15は、シート状あるいはグリッド状に形成されたものであり、例えば、ビニロン繊維、ガラス繊維、アラミド繊維などを用いた1軸、2軸、3軸繊維シート(繊維メッシュ)、不織布などの繊維シートやFRPグリッドなどが適用される。   On the other hand, in the suspended ceiling B of the present embodiment, the drop-off prevention member 15 is integrally attached to the ceiling surface of the ceiling material 6 using an adhesive. The drop-off prevention member 15 is formed in a sheet shape or a grid shape. For example, a uniaxial, biaxial, triaxial fiber sheet (fiber mesh), nonwoven fabric using vinylon fiber, glass fiber, aramid fiber, or the like is used. A fiber sheet such as FRP grid or the like is applied.

また、脱落防止部材15は、天井材6に接着剤を塗布したり、接着剤を含浸させて、天井材6の天井面の全体あるいは部分的に貼設される。 Further, the drop-off preventing member 15 is attached to the ceiling material 6 in whole or in part by applying an adhesive to the ceiling material 6 or impregnating the adhesive with the adhesive .

なお、脱落防止部材15は、その接着面に予め接着層(接着剤)を設け、剥離紙を接着層に取り付けて形成し、現場で剥離紙を剥離するとともに天井材6の天井面に接着層を接着させて貼設するようにしてもよい。この場合には、現場で接着剤を塗布したり、含浸させる必要がないため、意匠性の向上を図ることができる。また、脱落防止部材15の貼設作業に要する手間、労力を大幅に低減することができ、補強、改修時の施工性を大幅に向上させることができる。   The drop-off prevention member 15 is formed by providing an adhesive layer (adhesive) on the adhesive surface in advance, attaching the release paper to the adhesive layer, peeling the release paper on site, and attaching the adhesive layer to the ceiling surface of the ceiling material 6. May be adhered and pasted. In this case, since it is not necessary to apply or impregnate the adhesive on site, the design can be improved. Further, the labor and labor required for the work of attaching the drop-off prevention member 15 can be greatly reduced, and the workability during reinforcement and repair can be greatly improved.

また、接着剤で脱落防止部材15を天井材6に貼設する際には、脱落防止部材15(や含浸樹脂)の表面に仕上げ塗装を施すなどして意匠性の向上・確保を図るようにしてもよい。   In addition, when the drop-off prevention member 15 is attached to the ceiling member 6 with an adhesive, the surface of the drop-off prevention member 15 (or impregnated resin) is subjected to finish coating to improve and secure the design. May be.

さらに、図2に示すように、脱落防止部材15は複数の支持部材16を介して建物躯体に繋げられている。
具体的に、本実施形態では、支持部材16が、金物で構成されており、天井材6を貫通して配設される軸部16aと、軸部16aの一端部に繋がって横方向T1に延設され、天井材6との間で脱落防止部材15を挟み込むように配設される略円板状の係止部16bと、軸部16aの他端部側に下端側をネジ止めするなどして接続し、上端側を建物躯体(上部構造3)に接続し、軸部16a及び係止部16bを介して脱落防止部材15及び天井材6を吊り下げ支持する吊り部16cとを備えて構成されている。
Furthermore, as shown in FIG. 2, the dropout prevention member 15 is connected to the building frame via a plurality of support members 16.
Specifically, in the present embodiment, the support member 16 is made of hardware, and is connected to the shaft portion 16a disposed through the ceiling member 6 and one end portion of the shaft portion 16a in the lateral direction T1. A substantially disc-shaped locking portion 16b that is provided so as to sandwich the drop-off prevention member 15 between the ceiling member 6 and the lower end side is screwed to the other end side of the shaft portion 16a. The upper end side is connected to the building frame (upper structure 3), and the drop-off prevention member 15 and the hanging portion 16c for hanging and supporting the ceiling material 6 via the shaft portion 16a and the locking portion 16b are provided. It is configured.

そして、上記構成からなる本実施形態の吊り天井Bにおいては、天井材6の天井面にシート状及び/又は格子状の脱落防止部材15を接着剤で一体に貼設することによって、地震時に、天井下地7に天井材6を固着するビスなどに集中して応力が発生することを抑止できる。すなわち、ビス抜けや天井材6のコーン状破壊、プライアウト破壊などを抑止できる。これにより、天井材6の天井面の広範に脱落防止部材15を接着剤で貼設しておくことで、天井材6が剥落したり、脱落することを防止できる。   In the suspended ceiling B of the present embodiment having the above-described configuration, the sheet-like and / or lattice-like dropout prevention member 15 is integrally attached to the ceiling surface of the ceiling material 6 with an adhesive, so that during an earthquake, It is possible to prevent stress from being concentrated on a screw or the like that fixes the ceiling material 6 to the ceiling base 7. That is, it is possible to prevent screw dropout, cone-like destruction of the ceiling material 6, ply-out destruction, and the like. Thereby, it is possible to prevent the ceiling material 6 from peeling off or dropping off by attaching the drop-off preventing member 15 to the wide area of the ceiling surface of the ceiling material 6 with an adhesive.

また、万一、ビス周りに破損が生じた場合であっても、脱落防止部材15が貼設されているため、且つ脱落防止部材15が支持部材16を介して建物躯体3に繋げられているため、確実に天井材6が剥落したり、脱落することを防止できる。   Even in the event that damage occurs around the screw, the drop-off prevention member 15 is stuck, and the drop-off prevention member 15 is connected to the building housing 3 via the support member 16. Therefore, it is possible to reliably prevent the ceiling material 6 from peeling off or dropping off.

さらに、例えば、ビニロン繊維、ガラス繊維などを用いた繊維シート、FRPグリッドなどを脱落防止部材15として用いることで、安価で且つ確実に天井材6の剥落、脱落を防止することができる。また、ネットなどと比較し、維持管理もほとんど行う必要がない。   Furthermore, for example, by using a fiber sheet using vinylon fiber, glass fiber, or the like, an FRP grid, or the like as the drop-off preventing member 15, the ceiling material 6 can be prevented from being peeled off and dropped off at a low cost. Also, compared to the Internet, there is almost no need for maintenance.

よって、本実施形態の吊り天井Bによれば、従来のネットなどを用いる場合と比較し、外観を損なうことなく、且つ維持管理を不要またはその頻度を低減しつつ、地震時に天井材(天井パネル)6の破損や脱落が生じることを防止できる。また、小片等の脱落をも確実に防止することができる。さらに、補強と改修を同時に行うことが可能になる。さらに、例えば劇場や大会議室、展示施設などの天井高さが高い場合、天井面積が非常に大きな場合、天井が複雑な形状である場合であっても、脱落防止部材15を順次天井面に接着剤で貼設してゆけばよいため、容易且つ確実に適用することができる。すなわち、汎用性の高い天井材の脱落/剥落防止対策を提供することが可能になる。   Therefore, according to the suspended ceiling B of the present embodiment, compared with the case of using a conventional net or the like, the ceiling material (ceiling panel) can be used during an earthquake without impairing the external appearance and requiring no maintenance or reducing the frequency thereof. ) 6 can be prevented from being broken or dropped. In addition, it is possible to reliably prevent small pieces from falling off. In addition, reinforcement and repair can be performed simultaneously. Furthermore, even when the ceiling height of a theater, a large conference room, an exhibition facility, etc. is high, the ceiling area is very large, or the ceiling has a complicated shape, the drop-off prevention member 15 is sequentially placed on the ceiling surface. Since it should just stick with an adhesive agent, it can apply easily and reliably. That is, it is possible to provide a highly versatile ceiling material falling / falling prevention measure.

また、本実施形態の吊り天井Bにおいては、支持部材16が、天井材6を貫通して配設される軸部16aと、軸部16aの一端部に繋がって、天井材6との間で脱落防止部材15を挟み込むように配設される係止部16bと、軸部16aと建物躯体3に接続して脱落防止部材15及び天井材6を吊り下げ支持する吊り部16cとを備えていることにより、脱落防止部材15を一体に貼設した天井材6を支持部材16によって吊り下げ支持することができる。   In addition, in the suspended ceiling B of the present embodiment, the support member 16 is connected to the shaft portion 16 a disposed through the ceiling material 6 and one end of the shaft portion 16 a, and between the ceiling material 6. A locking portion 16b disposed so as to sandwich the dropout prevention member 15 and a suspension portion 16c connected to the shaft portion 16a and the building housing 3 to suspend and support the dropout prevention member 15 and the ceiling material 6 are provided. Thus, the ceiling member 6 on which the drop-off preventing member 15 is integrally attached can be suspended and supported by the support member 16.

すなわち、天井材6に接着剤で脱落防止部材15を貼設し、天井面側から天井材6に軸部16aを貫通させるとともに係止部16bを係止させ、天井裏空間Hで軸部16aと建物躯体3に吊り部16cを緊結することにより、確実且つ容易に、吊り天井Bに対して補強効果や改修効果を同時に付与することができる。   That is, the drop-off preventing member 15 is attached to the ceiling material 6 with an adhesive, the shaft portion 16a is penetrated from the ceiling surface 6 to the ceiling material 6 and the locking portion 16b is locked, and the shaft portion 16a in the ceiling back space H. By tightening the suspension portion 16c to the building housing 3, the reinforcing effect and the repair effect can be simultaneously and reliably imparted to the suspended ceiling B.

以上、本発明に係る吊り天井構造の一実施形態について説明したが、本発明は上記の一実施形態に限定されるものではなく、その趣旨を逸脱しない範囲で適宜変更可能である。   As mentioned above, although one embodiment of the suspended ceiling structure according to the present invention has been described, the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention.

例えば、本実施形態では、天井下地7が野縁1と野縁受け2を備えて構成されているものとしたが、本発明に係る天井下地は、必ずしも本実施形態のように限定しなくてもよく、例えば、吊りボルト(吊り部材)4に吊り下げ支持されて水平の一方向T1に所定の間隔をあけて並設されるとともに一方向T1に直交する他方向T2に延びる複数のTバー(断面逆T型の支持部材)8を備えて構成した天井下地7であってもよい。すなわち、本発明は、特に天井下地の構成を限定する必要はない。   For example, in the present embodiment, the ceiling foundation 7 is configured to include the field edge 1 and the field edge receiver 2, but the ceiling foundation according to the present invention is not necessarily limited to the present embodiment. For example, a plurality of T bars that are suspended and supported by the suspension bolts (suspending members) 4 and arranged in parallel in one horizontal direction T1 at a predetermined interval and extend in the other direction T2 orthogonal to the one direction T1. It may be a ceiling base 7 configured with a (cross-section inverted T-shaped support member) 8. That is, the present invention does not need to limit the configuration of the ceiling foundation.

また、支持部材16は、脱落防止部材15を建物躯体に繋げることが可能であれば、必ずしも本実施形態のように構成しなくてもよい。例えば、図3及び図4、図5に示すように、支持部材16としてグリッド材を用いるようにしてもよい(係止部をグリット状に形成するものも含む)。また、支持部材16は、図3及び図4に示すように、連結具17を用い、脱落防止部材15の端部を天井部5の端部側から上部構造(建物躯体)3に繋げるように形成・配設したり、図5に示すように、脱落防止部材15の端部を壁などの建物構成部材(建物躯体)9に繋げるように形成・配設してもよい。   Further, the support member 16 may not necessarily be configured as in the present embodiment as long as the dropout prevention member 15 can be connected to the building frame. For example, as shown in FIGS. 3, 4, and 5, a grid material may be used as the support member 16 (including a member that forms a locking portion in a grit shape). Further, as shown in FIGS. 3 and 4, the support member 16 uses a connector 17 so that the end portion of the drop-off prevention member 15 is connected to the upper structure (building frame) 3 from the end portion side of the ceiling portion 5. Alternatively, as shown in FIG. 5, the end of the drop-off prevention member 15 may be formed and disposed so as to be connected to a building component (building frame) 9 such as a wall.
