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を側壁見切材４０の保持溝４３に挿入して係合させることで側壁見切材４０の先端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３（ｂ）及び図４（ｂ）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、側壁見切材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 side wall parting material 40 and engaging it, the fitting part 51 is attached downward near the tip of the side wall parting material 40. As shown in FIGS. 3B and 4B, 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. The closing material 50 attached to the parting material 40 is formed so as not to easily fall off.

ここで、図３（ａ）及び図４（ａ）に示すように、側壁見切材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の長さは側壁見切材４０の水平延出部４２の下面と吊天井見切材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を側壁見切材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、側壁見切材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、側壁見切材４０と吊天井見切材３０の第１延出部３２の上面との間を塞いだ状態を維持することができる。   Here, as shown to Fig.3 (a) and FIG.4 (a), the front-end | tip of the side wall parting material 40 is located in the upper surface of the 1st extension part 32 of the suspended ceiling parting material 30, and is also a closing material. The length of the 50 sheet portions 52 is set to be longer than the distance between the lower surface of the horizontal extending portion 42 of the side wall parting material 40 and the upper surface of the first extending portion 32 of the suspended ceiling parting material 30. For this reason, when the closing material 50 is fixed downward in the vicinity of the tip of the side wall parting material 40, the sheet portion 52 of the closing material 50 is bent into an L-shape and is formed on the upper surface of the first extension part 32 of the suspended ceiling parting material 30. As a result, the space between the side wall parting material 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 first extension portion 32 of the suspended ceiling parting material 30 because it is in contact. . And since the sheet | seat part 52 can change a shape according to the shape of a contact surface, irrespective of the direction of shaking, the side wall parting material 40 and the upper surface of the 1st extension part 32 of the suspended ceiling parting material 30 It is possible to maintain a closed state.

以上説明したように、本実施形態によれば、側壁１０から間隙を隔てた位置で天井スラブ１１に吊り支持される吊天井２０を備えているため、地震が発生して横方向に揺れた場合でも、吊天井２０と側壁１０との間に間隙が設けられていることにより天井材２１などが側壁１０に衝突しづらく、破損、破壊による吊天井２０の落下を防止することができる。   As described above, according to the present embodiment, since the suspended ceiling 20 that is suspended and supported by the ceiling slab 11 is provided at a position spaced apart from the side wall 10, when an earthquake occurs and shakes laterally However, since the gap is provided between the suspended ceiling 20 and the side wall 10, the ceiling material 21 or the like hardly collides with the side wall 10, and the suspended ceiling 20 can be prevented from falling due to breakage or destruction.

また、前記側壁１０に固定される側壁見切材４０を備えているため、側壁１０と吊天井２０との間の間隙を側壁見切材４０で塞ぐことができ、美観を損なう事がない。また、この側壁見切材４０は、吊天井見切材３０より上方において前記側壁１０に固定されているため、地震が発生して横方向に揺れた場合でも、吊天井２０や吊天井見切材３０が側壁見切材４０と衝突しづらくなっている。しかも、側壁見切材４０は直接側壁１０へ固定できるため、下地材が不要であり、部品数を少なくしてコストを抑えることができる。   Moreover, since the side wall parting material 40 fixed to the side wall 10 is provided, the gap between the side wall 10 and the suspended ceiling 20 can be closed with the side wall parting material 40, and the aesthetic appearance is not impaired. Further, since the side wall parting material 40 is fixed to the side wall 10 above the suspended ceiling parting material 30, the suspended ceiling 20 and the suspended ceiling parting material 30 can be used even when an earthquake occurs and shakes in the lateral direction. It is difficult to collide with the side wall parting material 40. In addition, since the side wall parting material 40 can be directly fixed to the side wall 10, a base material is unnecessary, and the number of components can be reduced to reduce the cost.

更に、側壁見切材４０と吊天井見切材３０との間には塞ぎ手段としての塞ぎ材５０が設けられているので、側壁見切材４０と吊天井見切材３０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。   Furthermore, since the closing material 50 as a closing means is provided between the side wall parting material 40 and the suspended ceiling parting material 30, airtightness is maintained between the side wall parting material 40 and the suspended ceiling parting material 30. It is possible to make dust less likely to adhere by reducing the air passage.

また、前記塞ぎ材５０は、前記側壁見切材４０の先端付近に下向きに固定されるとともに、前記吊天井見切材３０に対して摺動可能に接触している。すなわち、塞ぎ材５０は、側壁見切材４０にのみ固定され、吊天井見切材３０に対しては固定されていないため、塞ぎ材５０が吊天井２０や吊天井見切材３０の動きを妨げることがない。   Further, the closing material 50 is fixed downward near the tip of the side wall parting material 40 and is slidably in contact with the suspended ceiling parting material 30. That is, since the closing material 50 is fixed only to the side wall parting material 40 and is not fixed to the suspended ceiling parting material 30, the closing material 50 may hinder the movement of the suspended ceiling 20 and the suspended ceiling parting material 30. Absent.
