*看板样式；广告牌架构，建于早期的昭和时期。通常地，地地板用作零售空间，在店面处显示窗口。

*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，保持公告牌架构的外观。第二，加强抗震改造。

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门十多年了。现有的建筑几乎被废弃，造成的破坏是灾难性的。虽然这似乎是不可能的，但客户强烈希望这座大楼能留下。我们决定拆迁整栋建筑，重建整个地基和受损的地基.

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.

地下没有抗震单元。如果我们选择普通的加固方式，例如：-承重墙或支撑

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.

采用球墨铸铁制作的拱架作为抗震元件，不干扰立面，机织形状来源于结构分析。每条纹的直径都会平滑地随结构内应力的变化而变化。

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.

铸造是制造众多零件最有效的方法，尤其是在形状复杂或具有装饰性的情况下。此外，铸铁的粗糙和温暖的质地，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.

虽然它是铸铁，但它是非常轻的，因为它非常薄和轻的框架，通过结构分析的三维参数化软件(蚱蜢)。铸铁机架的重量只有55公斤，因此可以通过人工组装。

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.
