🎍あけましておめでとうございます!🎍
⌇東京国際(羽田)空港🛫第2ターミナル国際線施設
近年の国際線発着枠増加に伴う施設機能の強化のため、本施設は、供用中の第2ターミナルに国際線施設の増築を行いました🍃
一方で、多様化する自然災害に対し、航空ネットワークを駆使した人的・物的拠点としての空港の役割を社会的にも重要視する現状があります。
上記のニーズに応える「新たな空港」を設計するため、「ハード整備での空港利用者の安全・安心確保」実現のため、性能試験やモックアップ検証、ディテールまでこだわりぬいて計画・設計・監理を行いました。
具体的には、「屋根の軽量化」「天井物の落下リスク軽減」「既存躯体への影響最小化」を計画コンセプトの軸とし、「ETFE膜によるクッションタイプ3層膜屋根構造」と「5つの円の曲げと重ねによるダイナミックな片持ち面的支持構造フレーム」を提案、具現化しています。特に、「ETFE膜によるクッションタイプ3層膜屋根構造」は、屋根耐火や屋根断熱の性能確保に向けた技術開発に取り組みました。これは、設計当時では世界初の技術であり、SDGsや日本の科学技術発展にもつながる取り組みとなりました。
Tokyo International (Haneda) Airport Terminal 2 International Flight Facilities
In order to strengthen the facility in response to the recent increase in the number of international flights, this facility is an extension of the international flight facilities in Terminal 2, and is currently in service.
At the same time, there is a current social emphasis on the airport's role as a multipurpose hub for the aviation network in response to a broad range of natural disasters.
In order to design a "new airport" that would meet the above needs, we planned, designed, and supervised the project through performance tests, mock-up verifications, and meticulous attention to detail in order to ensure the safety and security of airport users through hardware maintenance.
Specifically, the concept of the project was to "reduce the weight of the roof," "reduce the risk of falling objects from the ceiling," and "minimize the impact on the existing structure," and we proposed and realized a "cushion type 3-ply membrane roof structure using ETFE membranes" and a "dynamic cantilevered surface support structure frame using five bent and overlapping circles. In particular, the "cushion type 3-layer membrane roof structure using ETFE membranes" was developed as a technology to ensure the performance of fireproofing and roof insulation. At the time of its design, this was the world's first technology of its kind, and it was also an initiative that led to the SDGs and the further development of science and technology in Japan.
