[分割方立の突き合わせ部]
つぎに、分割方立44A、44Bの突き合わせ部について、図4~図6を参照して説明する。
[Butting part of divided mullions]
Next, the abutting portions of the divided mullions 44A and 44B will be explained with reference to FIGS. 4 to 6.

図4~図6に示すように、分割方立44A、44Bは、方立1cを左右方向に分割した形状を有し、施工時に分割方立44A、44B同士を突き合わせ、複数本の連結ネジ31を介して連結することで、方立1cが構成される。 As shown in FIGS. 4 to 6, the divided mullions 44A and 44B have a shape in which the mullion 1c is divided in the left and right direction.During construction, the divided mullions 44A and 44B are butted against each other, and a plurality of connecting screws 31 By connecting them through, a mullion 1c is constructed.

分割方立44A、44Bの突き合わせ部には、火災による熱で発泡し、突き合わせ部の隙間を塞ぐ加熱発泡材7が設けられる。例えば、図4及び図5に示す例では、加熱発泡材7を含む板形状の遮炎板71を分割方立44A、44Bの突き合わせ部に配置している。このような建具1によれば、分割方立44A、44Bの突き合わせ部には、火災による熱で発泡し、突き合わせ部の隙間を塞ぐ遮炎板71が設けられるので、火災時の遮炎性を向上させることができる。 A heated foaming material 7 is provided at the abutting portions of the divided mullions 44A and 44B, which foams due to heat from the fire and closes the gap at the abutting portions. For example, in the example shown in FIGS. 4 and 5, a plate-shaped flame shielding plate 71 containing the heated foaming material 7 is arranged at the abutting portion of the divided mullions 44A and 44B. According to such a fitting 1, the flame shielding plate 71 is provided at the butt part of the divided mullions 44A and 44B, which foams due to the heat caused by the fire and closes the gap between the butt parts, so that the flame shielding property in the event of a fire is improved. can be improved.

また、分割方立44A、44Bの突き合わせ部には、突き合わせ部における遮炎板71の屋外側に配置され、突き合わせ部への水の侵入を阻止する止水材81が設けられる。止水材81は、例えば、弾性変形可能なゴム質弾性材からなる線状のシール材である。このような建具1によれば、分割方立44A、44Bの突き合わせ部には、止水材81が設けられるので、平時の防水性を向上させることができる。また、止水材81は、遮炎板71よりも屋外側に配置されるので、水の侵入による遮炎板71の劣化も防止できる。 Furthermore, a water stop material 81 is provided at the abutting portions of the divided mullions 44A and 44B, which is disposed on the outdoor side of the flame shield plate 71 at the abutting portions and prevents water from entering the abutting portions. The water stop material 81 is, for example, a linear sealing material made of an elastically deformable rubbery elastic material. According to such a fitting 1, since the water stop material 81 is provided at the abutting portions of the divided mullions 44A and 44B, the waterproofness during normal times can be improved. Moreover, since the water stop material 81 is arranged on the outdoor side of the flame shield plate 71, deterioration of the flame shield plate 71 due to water intrusion can be prevented.

また、分割方立44A、44Bの突き合わせ部には、前述した遮炎板71(第1加熱発泡材)や、その屋外側に配置される止水材81(第1止水材)に加えて、突き合わせ部における遮炎板71の屋内側に配置される第2の遮炎板72(第2加熱発泡材)と、突き合わせ部における遮炎板71の屋内側で、かつ第2の遮炎板72の屋外側に配置される第2の止水材82(第2止水材)と、が設けられる。このような建具1によれば、分割方立44A、44Bの突き合わせ部には、屋外側から順番に、第1の止水材81、第1の遮炎板71、第2の止水材82及び第2の遮炎板72が配置されるので、平時の防水性及び火災時の遮炎性をさらに向上させることができる。 Furthermore, in addition to the above-mentioned flame shielding plate 71 (first heated foam material) and water-stopping material 81 (first water-stopping material) disposed on the outdoor side, the butting portions of the divided mullions 44A and 44B are provided. , a second flame shielding plate 72 (second heating foam material) disposed on the indoor side of the flame shielding plate 71 at the abutting portion, and a second flame shielding plate located on the indoor side of the flame shielding plate 71 at the abutting portion. A second water-stopping material 82 (second water-stopping material) disposed on the outdoor side of 72 is provided. According to such a fitting 1, the first water-stopping material 81, the first flame-shielding plate 71, and the second water-stopping material 82 are placed at the abutting portions of the divided mullions 44A and 44B in order from the outdoor side. Since the second flame shielding plate 72 is arranged, the waterproof property in normal times and the flame blocking property in the event of a fire can be further improved.

つぎに、遮炎板71、72及び止水材81、82を配置するための分割方立44A、44Bの具体的な構成について、図5を参照して説明する。 Next, a specific configuration of the divided mullions 44A, 44B for arranging the flame shielding plates 71, 72 and the water stop materials 81, 82 will be described with reference to FIG.

図5に示すように、突き合わせ部における一方又は両方の分割方立44A、44Bには、分割方立44A、44Bを連結する際に他方の分割方立44A、44Bと当接又は近接し、突き合わせ部に遮炎板71、72の配置空間S1、S2を形成する複数の突部44a、44b、44c、44dが形成される。このような建具1によれば、分割方立44A、44Bを連結する際に遮炎板71、72が潰れたり、遮炎板71、72が位置ずれすることを防止できる。 As shown in FIG. 5, one or both of the divided mullions 44A, 44B at the abutting portion may come into contact with or be close to the other divided mullions 44A, 44B when connecting the divided mullions 44A, 44B, and the butt A plurality of protrusions 44a, 44b, 44c, and 44d are formed in the portion to form placement spaces S1 and S2 for the flame shield plates 71 and 72. According to such a fitting 1, it is possible to prevent the flame shield plates 71 and 72 from being crushed and from being displaced when the divided mullions 44A and 44B are connected.

図5に示すように、突き合わせ部における一方の分割方立44Bには、止水材81、82を収容する溝部44e、44fが形成される。また、突き合わせ部における他方の分割方立44Aには、分割方立44A、44Bを連結する際に、溝部44e、44fに収容された止水材81、82を押圧して弾性変形させる押圧部44g、44hが形成される。このような建具1によれば、止水材81、82を確実に機能させ、平時の防水性をさらに向上させることができる。 As shown in FIG. 5, groove portions 44e and 44f for accommodating water stop materials 81 and 82 are formed in one of the divided mullions 44B in the abutting portion.
