図7、図8は、従来のカーテンウォール100のシール構造の例を示す断面図である。図7は、横枠101の長手方向に直交する断面の一部を示している。図8は、図7のY−Y線で切断した断面図であり、横枠101と縦枠102の連結部を示している。
図示のように、カーテンウォール100は、枠材である横枠101及び縦枠102と、横枠101の長手方向に沿って装着されるシール部材103を備えている。シール部材103が横枠101の装着溝104に装着されて、シール部材103の端部106が横枠101の端面105とともに縦枠102の当接面107に当接している。
7 and 8 are cross-sectional views showing an example of a seal structure of a conventional curtain wall 100. FIG. 7 shows a part of a cross section orthogonal to the longitudinal direction of the horizontal frame 101. FIG. 8 is a cross-sectional view taken along the line YY of FIG. 7, showing a connecting portion between the horizontal frame 101 and the vertical frame 102.
As shown in the figure, the curtain wall 100 includes a horizontal frame 101 and a vertical frame 102, which are frame materials, and a seal member 103 mounted along the longitudinal direction of the horizontal frame 101. The seal member 103 is mounted in the mounting groove 104 of the horizontal frame 101, and the end portion 106 of the seal member 103 is in contact with the contact surface 107 of the vertical frame 102 together with the end surface 105 of the horizontal frame 101.

シール部材103と当接面107の間の部分をシールするためには、シール部材103の端部106を当接面107に密着させる必要がある。これに対し、従来のカーテンウォール100では、シール部材103の経年変化や収縮等に伴い、シール部材103の端部106が当接面107から離れるのを防止するため、シール部材103の端部106を接着剤により当接面107に接着している。従って、シール部材103の端部106と当接面107との密着を維持するために、接着の作業等を行う必要があり、手間がかかる。また、当接面107におけるシール部材103によるシールをより確実に行う観点からも、改良が求められている。 In order to seal the portion between the sealing member 103 and the contact surface 107, it is necessary to bring the end portion 106 of the sealing member 103 into close contact with the contact surface 107. On the other hand, in the conventional curtain wall 100, the end portion 106 of the seal member 103 is prevented from being separated from the contact surface 107 due to aging or shrinkage of the seal member 103. Is adhered to the contact surface 107 with an adhesive. Therefore, in order to maintain the close contact between the end portion 106 of the seal member 103 and the contact surface 107, it is necessary to perform an adhesive operation or the like, which is troublesome. Further, improvement is required from the viewpoint of more reliably sealing the contact surface 107 with the seal member 103.

シール部材30は、配置部42の隙間49を通過して折り返し、シール部材30の折り返し部31は、隙間49において、押圧部47と縦枠7の当接面7Gとの間に配置される。押圧部47は、折り返されたシール部材30の間に配置されて、シール部材30の折り返し部31と当接する。配置部42において、シール部材30の折り返し部31は、押圧部47と縦枠7の当接面7Gに当接し、押圧部47と当接面7Gの間で幅方向に圧縮されて弾性変形する。その結果、シール部材30の折り返し部31は、復元力により、当接面7Gに向かって押圧されて、当接面7Gに圧着される。 The seal member 30 passes through the gap 49 of the arrangement portion 42 and is folded back, and the folded portion 31 of the seal member 30 is arranged between the pressing portion 47 and the contact surface 7G of the vertical frame 7 in the gap 49. The pressing portion 47 is arranged between the folded seal members 30 and comes into contact with the folded portion 31 of the seal member 30. In the arrangement portion 42, the folded portion 31 of the seal member 30 abuts on the contact surface 7G of the pressing portion 47 and the vertical frame 7, and is compressed in the width direction between the pressing portion 47 and the contact surface 7G to be elastically deformed. .. As a result, the folded-back portion 31 of the seal member 30 is pressed toward the contact surface 7G by the restoring force and is crimped to the contact surface 7G.

枠体3を組み立てるときには、シール部材30を配置部42で折り返して保持部材20の装着部40、41に装着する。その状態で、保持部材20を横枠本体4Aに取り付ける。これにより、保持部材20の対向部23と横枠本体4Aの対向部4Dを互いに対向して配置し、シール部材30を2つの対向部23、4Dの間に挟む。続いて、横枠4の端面4Mを縦枠7の当接面7Gに当接して、横枠4と縦枠7を連結する。配置部42で、シール部材30の折り返し部31は、縦枠7の当接面7Gに当接して、当接面7Gに押し付けられる。 When assembling the frame body 3, the seal member 30 is folded back at the arrangement portion 42 and attached to the attachment portions 40 and 41 of the holding member 20. In that state, the holding member 20 is attached to the horizontal frame main body 4A. As a result, the facing portion 23 of the holding member 20 and the facing portion 4D of the horizontal frame main body 4A are arranged so as to face each other, and the seal member 30 is sandwiched between the two facing portions 23 and 4D. Subsequently, the end surface 4M of the horizontal frame 4 is brought into contact with the contact surface 7G of the vertical frame 7 to connect the horizontal frame 4 and the vertical frame 7. In the arrangement portion 42, the folded portion 31 of the seal member 30 abuts on the contact surface 7G of the vertical frame 7 and is pressed against the contact surface 7G.

以上説明したように、配置部42でシール部材30を折り返すことで、シール部材30の折り返し部31を縦枠7の当接面7Gに押し付けて、シール部材30の折り返し部31と当接面7Gを密着することができる。そのため、シール部材30を横枠4の端面4Mとともに縦枠7の当接面7Gに簡単に密着させて、当接面7Gにおけるシール部材30によるシールを確実に行うことができる。シール部材30を横枠本体4Aの対向部4Dに押し付けることで、当接面7Gに加えて、対向部23、4Dの間でも、シール部材30によるシールを行うことができる。 As described above, by folding back the seal member 30 at the arrangement portion 42, the folded portion 31 of the seal member 30 is pressed against the contact surface 7G of the vertical frame 7, and the folded portion 31 and the contact surface 7G of the seal member 30 are pressed. Can be in close contact. Therefore, the seal member 30 can be easily brought into close contact with the contact surface 7G of the vertical frame 7 together with the end surface 4M of the horizontal frame 4, and the seal member 30 can reliably seal the contact surface 7G. By pressing the sealing member 30 against the facing portion 4D of the horizontal frame main body 4A, the sealing member 30 can perform sealing between the facing portions 23 and 4D in addition to the contact surface 7G.

配置部42に設けられた保持部材20の押圧部47により、隙間49を通過するシール部材30の折り返し部31を縦枠7の当接面7Gに確実に密着して、シール部材30によるシール性能を向上することができる。装着部40、41が装着溝であり、押圧部47が2列の装着部40、41の間の第3壁部45の端部48である。そのため、装着部40、41と配置部42の構造が複雑になるのを抑制しつつ、シール部材30の折り返し部31を当接面7Gに容易に密着することができる。 The pressing portion 47 of the holding member 20 provided in the arranging portion 42 ensures that the folded portion 31 of the sealing member 30 passing through the gap 49 is firmly adhered to the contact surface 7G of the vertical frame 7, and the sealing performance by the sealing member 30. Can be improved. The mounting portions 40 and 41 are mounting grooves, and the pressing portion 47 is an end portion 48 of the third wall portion 45 between the mounting portions 40 and 41 in two rows. Therefore, the folded portion 31 of the seal member 30 can be easily brought into close contact with the contact surface 7G while suppressing the structure of the mounting portions 40 and 41 and the arranging portion 42 from becoming complicated.

シール部材30によるシール構造に要求される機能や性能等に対応して、2列の装着部40、41を使い分けて、シール部材30の装着部40、41への装着の仕方を容易に変更することができる。例えば、シール部材30を枠体3の外周部側の第1装着部40に装着して第1装着部40の端部から第2装着部41の端部に折り返し、シール部材30の端部32を枠体3の内周部側の第2装着部41に装着する。このようにすることで、シール部材30の端部32が外周部側に位置するのを防止し、外周部側のシール部材30により、枠体3の外周部側から内周部側に向かう気体や水を止めることができる。従って、シール部材30によるシール構造をカーテンウォール1及びカーテンウォールユニット2に適用したときに、大きな効果が得られる。 The method of mounting the seal member 30 to the mounting portions 40 and 41 can be easily changed by properly using the two rows of mounting portions 40 and 41 according to the functions and performance required for the sealing structure of the sealing member 30. be able to. For example, the seal member 30 is attached to the first mounting portion 40 on the outer peripheral portion side of the frame body 3, folded back from the end portion of the first mounting portion 40 to the end portion of the second mounting portion 41, and the end portion 32 of the seal member 30. Is mounted on the second mounting portion 41 on the inner peripheral portion side of the frame body 3. By doing so, the end portion 32 of the seal member 30 is prevented from being located on the outer peripheral portion side, and the gas toward the inner peripheral portion side from the outer peripheral portion side of the frame body 3 by the seal member 30 on the outer peripheral portion side. And water can be stopped. Therefore, when the sealing structure by the sealing member 30 is applied to the curtain wall 1 and the curtain wall unit 2, a great effect can be obtained.

これに対し、シール部材30を第2装着部41に装着して第2装着部41の端部から第1装着部40の端部に折り返し、シール部材30の端部32を第1装着部40に装着してもよい。この場合には、シール部材30は、第2装着部41に装着されて、第2装着部41及び横枠4の長手方向に沿って配置される。また、シール部材30は、配置部42で、第2装着部41から第1装着部40に折り返して、第1装着部40に装着される。シール部材30の端部32は、第1装着部40に装着される。このようにすることで、シール部材30の端部32が内周部側に位置するのを防止し、内周部側のシール部材30により、枠体3の内周部側から外周部側に向かう気体や水を止めることができる。 On the other hand, the seal member 30 is mounted on the second mounting portion 41 and folded back from the end portion of the second mounting portion 41 to the end portion of the first mounting portion 40, and the end portion 32 of the seal member 30 is attached to the first mounting portion 40. It may be attached to. In this case, the seal member 30 is mounted on the second mounting portion 41 and is arranged along the longitudinal direction of the second mounting portion 41 and the horizontal frame 4. Further, the seal member 30 is folded back from the second mounting portion 41 to the first mounting portion 40 at the arranging portion 42, and is mounted on the first mounting portion 40. The end portion 32 of the seal member 30 is attached to the first attachment portion 40. By doing so, it is possible to prevent the end portion 32 of the seal member 30 from being located on the inner peripheral portion side, and the seal member 30 on the inner peripheral portion side causes the frame body 3 to move from the inner peripheral portion side to the outer peripheral portion side. You can stop the gas and water that are heading.

なお、装着部40、41の長手方向の全体にシール部材30を装着してもよく、装着部40、41の長手方向の一部にシール部材30を装着してもよい。シール部材30は、例えば、気密用のシール部材であってもよく、水密用のシール部材であってもよい。装着部40、41は、シール部材30が装着可能な部分であればよく、溝状の装着溝以外の装着部であってもよい。装着部40、41は、保持部材20の対向部23に限定されず、互いの対向部において対向する2つの部材のうちの一方の部材の対向部に設けることができる。そのため、装着部40、41を横枠本体4Aの対向部4Dに設けて、シール部材30を保持部材20の対向部23に押し付けてもよい。 The seal member 30 may be mounted on the entire longitudinal direction of the mounting portions 40 and 41, or the seal member 30 may be mounted on a part of the mounting portions 40 and 41 in the longitudinal direction. The seal member 30 may be, for example, an airtight seal member or a watertight seal member. The mounting portions 40 and 41 may be any portion as long as the sealing member 30 can be mounted, and may be a mounting portion other than the groove-shaped mounting groove. The mounting portions 40 and 41 are not limited to the facing portions 23 of the holding member 20, and may be provided on the facing portions of one of the two facing members in the facing portions. Therefore, the mounting portions 40 and 41 may be provided on the facing portion 4D of the horizontal frame main body 4A, and the seal member 30 may be pressed against the facing portion 23 of the holding member 20.

ここでは、装着部40、41と配置部42を設ける第1枠材が横枠4であり、シール部材30の折り返し部31を押し付ける第2枠材が縦枠7である。これに対し、第1枠材は横枠4以外の枠材(例えば、縦枠、方立)であってもよく、第2枠材は縦枠以外の枠材(例えば、横枠、方立)であってもよい。 Here, the first frame material for providing the mounting portions 40 and 41 and the arranging portion 42 is the horizontal frame 4, and the second frame material for pressing the folded-back portion 31 of the seal member 30 is the vertical frame 7. On the other hand, the first frame material may be a frame material other than the horizontal frame 4 (for example, vertical frame, mullion), and the second frame material may be a frame material other than the vertical frame (for example, horizontal frame, mullion). ) May be.

シール部材30によるシール構造は、カーテンウォールユニット2の枠体3に限定されず、種々の枠体の枠材に適用することができる。また、枠体は、枠材により枠状に形成された枠状体であり、枠体3以外の枠体(例えば、カーテンウォールの枠状部分、建具の枠体、障子の框体)であってもよい。従って、枠材は、枠状に組み合わされる枠体用部材であり、枠体3の枠以外のカーテンウォールの枠材(例えば、方立、無目、縦材、横材)であってもよく、カーテンウォールの枠材以外の枠材(例えば、建具の枠体の枠、障子の框体の框)であってもよい。 The sealing structure by the sealing member 30 is not limited to the frame body 3 of the curtain wall unit 2, and can be applied to the frame materials of various frame bodies. The frame is a frame formed by a frame material, and is a frame other than the frame 3 (for example, a frame of a curtain wall, a frame of a fitting, a frame of a shoji). You may. Therefore, the frame material is a frame body member to be combined in a frame shape, and may be a frame material of a curtain wall other than the frame of the frame body 3 (for example, a mullion, a transom light, a vertical material, a horizontal material). , A frame material other than the frame material of the curtain wall (for example, the frame of the frame of the fitting, the frame of the frame of the shoji) may be used.
