The gap S1
, S3 is not limited to a mode wider than the gaps S2, S4, and may be the same as the gaps S2, S4.

そして、本実施形態においては、第１の吊天井２０Ａと第２の吊天井２０Ｂとの間には塞ぎ手段としての塞ぎ材５０が設けられている。この塞ぎ材５０を設けることで、第１の吊天井２０Ａと吊天井見切材３０との間で気密性を保って空気の通りを少なくすることでほこりなどを付着し難くしている。   In the present embodiment, a closing material 50 as a closing means is provided between the first suspended ceiling 20A and the second suspended ceiling 20B. By providing this closing material 50, it is difficult to adhere dust or the like by keeping airtightness between the first suspended ceiling 20A and the suspended ceiling parting material 30 and reducing the passage of air.

塞ぎ材５０は、図７に示すように、塩化ビニル等で形成された可撓性のシート部５２と、このシート部５２の一端縁に設けられた嵌入部５１と、を備えており、この嵌入部５１を塞ぎ材ホルダー４０の保持溝４３に挿入して係合させることで塞ぎ材ホルダー４０の先端付近（第１の吊天井２０Ａの端縁付近）に下向きに取り付けられる。なお、保持溝４３と嵌入部５１との接触面には、図４及び図６に示すように、抜け止め方向に互いに噛合する逆止爪形状が形成されており、塞ぎ材ホルダー４０に取り付けた塞ぎ材５０が容易に脱落しないように形成されている。
As shown in FIG. 7, the closing material 50 includes a flexible sheet portion 52 formed of vinyl chloride or the like, and a fitting portion 51 provided at one end edge of the sheet portion 52. By inserting the engaging portion 51 into the holding groove 43 of the closing material holder 40 and engaging it, the fitting portion 51 is attached downward near the tip of the closing material holder 40 (in the vicinity of the edge of the first suspended ceiling 20A). As shown in FIGS. 4 and 6, the contact surface between the holding groove 43 and the fitting portion 51 is formed with a check claw shape that meshes with each other in the retaining direction, and is attached to the closing material holder 40. The closing material 50 is formed so as not to easily fall off.

ここで、図３及び図５に示すように、塞ぎ材ホルダー４０の先端は吊天井見切材３０の第１延出部３２の上面に位置しており、また、塞ぎ材５０のシート部５２の長さは塞ぎ材ホルダー４０の下垂部４２の下端と吊天井見切材３０の第１延出部３２の上面との間の距離よりも長く設定されている。このため、塞ぎ材５０を塞ぎ材ホルダー４０の先端付近に下向きに固定すると、塞ぎ材５０のシート部５２はＬ字状に折り曲げられて吊天井見切材３０の第１延出部３２の上面に載った状態となり、塞ぎ材ホルダー４０と吊天井見切材３０との間が塞ぎ材５０のシート部５２でほぼ完全に塞がれる。このとき、塞ぎ材５０のシート部５２は吊天井見切材３０に対して固定されておらず、吊天井見切材３０の第１延出部３２の上面で吊天井見切材３０に摺動可能に接触しているだけのため、もしこの状態で地震などの揺れが発生すると、塞ぎ材５０のシート部５２は吊天井見切材３０の第１延出部３２の上面で滑りながら移動することとなる。しかも、シート部５２は接触面の形状に合わせて形状を変化させることができるので、揺れの方向にかかわらず、第１の吊天井２０Ａと吊天井見切材３０との間を塞いだ状態を維持することができる。   Here, as shown in FIGS. 3 and 5, the end of the closing material holder 40 is located on the upper surface of the first extending portion 32 of the suspended ceiling parting material 30, and the sheet portion 52 of the closing material 50 The length is set longer than the distance between the lower end of the hanging part 42 of the closing material holder 40 and the upper surface of the first extension part 32 of the suspended ceiling parting material 30. For this reason, when the closing material 50 is fixed downward near the front end of the closing material holder 40, the sheet portion 52 of the closing material 50 is bent into an L shape so as to be placed on the upper surface of the first extension portion 32 of the suspended ceiling parting material 30. Thus, the space between the closing material holder 40 and the suspended ceiling parting material 30 is almost completely closed by the sheet portion 52 of the closing material 50. At this time, the sheet portion 52 of the closing material 50 is not fixed to the suspended ceiling parting material 30, and can slide on the suspended ceiling parting material 30 on the upper surface of the first extension part 32 of the suspended ceiling parting material 30. If the vibration such as an earthquake occurs in this state, the sheet portion 52 of the closing material 50 moves while sliding on the upper surface of the first extension portion 32 of the suspended ceiling parting material 30. . Moreover, since the shape of the seat portion 52 can be changed in accordance with the shape of the contact surface, the state where the space between the first suspended ceiling 20A and the suspended ceiling parting material 30 is closed is maintained regardless of the direction of shaking. can do.

以上説明したように、本実施形態によれば、第１の吊天井２０Ａと第２の吊天井２０Ｂとが別体かつ高さが異なるように設けられているため、地震が発生して横方向に揺れた場合でも、第１の吊天井２０Ａと第２の吊天井２０Ｂとの間に間隙が設けられていることにより互いに衝突しづらく、破損、破壊による吊天井２０Ａ、２０Ｂの落下を防止することができる。   As described above, according to the present embodiment, since the first suspended ceiling 20A and the second suspended ceiling 20B are provided as separate bodies and different in height, an earthquake occurs and the horizontal direction Even if it sways, it is difficult to collide with each other because the gap is provided between the first suspended ceiling 20A and the second suspended ceiling 20B, and the suspended ceilings 20A and 20B are prevented from falling due to breakage or destruction. be able to.

また、第１の吊天井２０Ａと第２の吊天井２０Ｂとに天井材２１が設けられているため、統一感が生まれ、意匠性が良い。   Further, since the ceiling material 21 is provided on the first suspended ceiling 20A and the second suspended ceiling 20B, a sense of unity is born and the design is good.

また、第１の吊天井２０Ａと第２の吊天井２０Ｂとの間に塞ぎ材５０を設けているため、間隙を塞ぎ材５０で塞ぐことができ、美観を損なう事がない。   Moreover, since the closing material 50 is provided between the first suspended ceiling 20A and the second suspended ceiling 20B, the gap can be closed with the closing material 50, and the aesthetic appearance is not impaired.

また、塞ぎ材５０を設けたことにより、第１の吊天井２０Ａと第２の吊天井２０Ｂとの間で気密性を保つことができ、空気の通りを少なくすることでほこりなどが付着し難くすることができる。   Further, by providing the closing material 50, airtightness can be maintained between the first suspended ceiling 20A and the second suspended ceiling 20B, and dust and the like are less likely to adhere by reducing the passage of air. can do.

また、第１の吊天井２０Ａは、野縁受け材２２が固定金具２６で固定されることで側壁１０に接合されており、第１の吊天井２０Ａが側壁１０と一体化するため、強固に固定することができる。   In addition, the first suspended ceiling 20A is joined to the side wall 10 by fixing the field edge receiving member 22 with the fixing bracket 26, and the first suspended ceiling 20A is integrated with the side wall 10, so that the first suspended ceiling 20A is firmly Can be fixed.

Falling can be prevented.

また、塞ぎ材５０は、前記第１の吊天井２０Ａの端縁付近に設けられた塞ぎ材ホルダー４０に下向きに固定され、前記第２の吊天井２０Ｂの端縁に固定された吊天井見切材３０に対して摺動可能に接触している。このため、塞ぎ材５０は、第１の吊天井２０Ａにのみ固定され、第２の吊天井２０Ｂに対しては固定されていないため、塞ぎ材５０が第２の吊天井２０Ｂの動きを妨げることがない。   Further, the closing material 50 is fixed downward to a closing material holder 40 provided in the vicinity of the edge of the first suspended ceiling 20A, and the suspended ceiling parting material fixed to the edge of the second suspended ceiling 20B. 30 is slidably contacted. For this reason, since the closing material 50 is fixed only to the first suspended ceiling 20A and is not fixed to the second suspended ceiling 20B, the closing material 50 prevents the movement of the second suspended ceiling 20B. There is no.

また、天井材２１をアルミニウムスパンドレルで構成しているため、吊天井見切材３０と天井材２１と同材質で形成することができ、統一感のある意匠を提供できる。   Moreover, since the ceiling material 21 is comprised with the aluminum spandrel, it can form with the same material as the suspension ceiling parting material 30 and the ceiling material 21, and can provide the design with a sense of unity.
