*KANBAN风格；广告牌建筑，建于昭和初期。通常情况下，底层作为零售空间，在店面有展示窗口。

*KANBAN-style; Billboard architecture, built in the early Showa period. Typically the ground floor is served as retail space, with displaying windows at the storefront.

客户的要求很简单。首先，要保持广告牌建筑的外墙。第二，实施抗震改造，以抵御地震。

The client’s request was simple. First, to keep the facade of the Billboard architecture. Second, to enforce seismic retrofit to resist earthquakes.

有一家裁缝店已经关闭了十多年。现有的建筑几乎被遗弃，破坏程度是灾难性的。虽然看起来不可能，但客户强烈希望该建筑能保留下来。我们决定将整栋建筑抬起来，重建整个地基和受损部分。

There was a tailor shop closed for over ten years. The existing building was almost abandoned, and the damage was disastrous. Although it seemed impossible, the client strongly wished for the building to remain. We decided to lift-up the complete building, and reconstruct the whole foundation and damaged elements.

地面层没有抗震元素。如果我们选择普通的加固方式，例如。-如果我们选择普通的加固方式，如：承重墙或支架，就不可能保留原来的开放店面。

There was no earthquake resisting elements at ground floor. If we chosen ordinary way of reinforcement, such as: -bearing wall or brace-, it was impossible to keep the original facade with an open storefront.

我们采用了球墨铸铁制成的拱形框架作为抗震元素，以避免干扰外墙。其编织的形状来自于结构分析。每个条纹的直径都会根据结构的内应力而平滑地变化。

We applied an arch-frame made of Ductile Cast Iron as earthquake resisting elements not to disturb the facade. Its woven likes shape comes from structural analysis. The diameter of each stripes transforms smoothly to follow structural internal stress.

铸造是生产众多部件的最有效方式，特别是当其形状复杂或具有装饰性时。此外，由于其粗糙和温暖的质地，铸铁适合现有的旧木材结构。

Casting was the most efficient way to produce numerous parts, especially when its shape is complicated or decorative. Furthermore, of its rough and warm texture, Cast Iron suited the existing old timber structure.

虽然是铸铁，但它非常轻，因为通过三维参数化软件（Grasshopper）的结构分析，它的框架非常薄和轻。 铸铁框架的重量只有55公斤，所以可以通过人力进行组装。
*商店的空间现在是租给EDOKIRIKO玻璃店。

Although it is the Cast Iron, it is very light, because of its extremely thin and light frame by structural analysis with the 3D parametric software (Grasshopper). The weight of the cast iron frame is only 55 kilograms, so it is possible to assemble by manpower.
*Store space is now rent for EDOKIRIKO glass shop.
