日本树形结构小教堂 Agri Chapel

Agri Chapel是一间位于日本长崎市的木质结构教堂，由日本的百枝優建筑设计事务所设计。空间由交错的桁架组成，采用纯粹的日式木工艺，打造出独特的和风哥特主义。教堂被环抱在一个大型的国家公园，可以直接眺望大海，景观十分优美。
Agri Chapel is a Japanese-wooden chapel with a fractal structure system designed by Yu Momoeda Architecture. They tried to design the building as a new gothic style chapel, by using Japanese wooden system. The site is surrounded by a large national park overlooking the sea.
于是，在设计之初，设计团队就希望这个教堂可以和自然环境和谐共处，融合在周围的景致里。长崎市原本有一间名为“大浦天主堂”的哥特式木教堂，历史非常悠久，不但成为了旅游地标，还深受当地居民的关注与喜爱。设计团队深受启发，希望可以打造一个新的地标式哥特教堂，并且让日本本土的木结构工艺成为空间的主要元素。
We tried to connect the activity of the chapel to the natural surroundings seamlessly. In Nagasaki, there is an oldest wooden gothic chapel in Japan known as “Ohura-Tenshudou”. This chapel is not only a famous tourist point, but a place loved and cared by the townsfolk. We tried to design the building as a new gothic style chapel, by using Japanese wooden system.
设计团队用一个个独立的木质单元向上伸展，用逐级缩小的形式扩散，组合成为一个树形的立体拱顶。
We created a pendentive dome by piling up a tree-like unit that extends upward by shrinking and increasing.
整个拱顶的支撑都基于4个120mm见方的柱体单元，第二层则由8个90mm见方的柱体单元组成，最后一层由16个60mm见方的柱体单元组成，这三层结构组合在一起，就是我们最终看到的空间构成。
Starting by four 120mm square pillars units, the second layer is composed by eight (4+1/2*8) 90mm square pillars units, and the last layer by sixteen 60mm square pillars units.
通过减少地板附近的柱子，可以提供更多的可利用空间。这些如同树冠一般的木质结构，采用的都是纯粹的日式工艺。四面的承重墙分担了空间的水平力，而这些木质但愿结构则支撑了屋顶重达25吨的重量。
We could provide usable open space by reducing the pillars near floor level. These tree-like units are constructed by Japanese wooden system. The four corner bearing walls undertake the horizontal force, and the inner wooden unit supports roof load which count up to 25 tons.
整个设计包含了哥特式教堂的三大特点，三层式结构、环绕式廊道、45度旋转的肋骨拱顶，将空间与结构有机地融合在一起，形成了独树一帜的室内景观。
This includes characteristics seen in gothic chapels such as three layered composition, nave / side corridor, 45 degrees rotation, which integrates structure, space, and interior.
