Description

本開示は、建具に関する。 The present disclosure relates to fittings.

従来、上枠を有する枠体と、枠体内の室外側に配置される外障子と、枠体内の室内側に配置される内障子と、を備える建具が知られている（例えば、特許文献１参照）。特許文献１に記載の上枠は、枠体の外周側に配置される金属製形材と、枠体の内周側に配置される樹脂製形材と、を備える。金属製形材は、中空部を有するホロー構造の形材で形成される。これにより、上枠の外周側に配置される金属製形材が中空部を有することにより、火災時の耐火強度や耐風圧性能を高めることができる。 Conventionally, fittings including a frame body having an upper frame, an outer shoji placed outside the frame body, and an inner shoji placed inside the frame body are known (for example, Patent Document 1 reference). The upper frame described in Patent Literature 1 includes a metal shaped member arranged on the outer peripheral side of the frame and a resin shaped member arranged on the inner peripheral side of the frame. The metal profile is formed of a hollow profile having a hollow portion. As a result, since the metal shape member arranged on the outer peripheral side of the upper frame has a hollow portion, fire resistance strength and wind pressure resistance performance in the event of a fire can be enhanced.

特開２０１８－５３５８９号公報JP 2018-53589 A

上枠の外周側に配置される金属製形材が中空部を有する場合には、その影響により、上枠の金属製形材の外部に露出される表面積が大きくなる。これにより、上枠の金属製形材において、冷気が接触する面積が大きくなるため、断熱性能や防露性能の低下の虞れがある。従って、耐火強度及び耐風圧性能を高めつつ、断熱性能及び防露性能を向上させることが求められている。 In the case where the metal shape member arranged on the outer peripheral side of the upper frame has a hollow portion, the surface area exposed to the outside of the metal shape member of the upper frame is increased due to its influence. As a result, the area of the metallic shape member of the upper frame that is in contact with the cold air is increased, and there is a risk that the heat insulating performance and anti-condensing performance will be degraded. Therefore, it is required to improve heat insulating performance and dewproof performance while increasing fire resistance and wind pressure resistance.

本開示は、耐火強度及び耐風圧性能を高めつつ、断熱性能及び防露性能を向上させることができる建具を提供することを目的とする。 An object of the present disclosure is to provide fittings capable of improving heat insulation performance and dew prevention performance while enhancing fire resistance and wind pressure resistance.
