The Accordion Arch是Atelier YokYok带领法国奥尔良ESAD高等艺术设计学院（France ESAD Orléans)）学生进行的一个模块化实验项目，该项目也是ESAD Orléans模块结构研究项目的一部分，计划在法国Chambord城堡（Château de Chambord）的马厩中建造。2019年1月，Atelier YokYok与ESAD的学生组织了第一阶段的设计工作坊并于2019年4月开始开始了专门用来施工建造的第二阶段，在这一阶段Atelier YokYok与ESAD的学生按1：1的比例建造在第一阶段的设计的Accordion Arch装置。目前The Accordion Arch装置将于2019年4月19日前在ESAD Orléans向公众展出。

The Accordion Arch is an experimental project about modular structures. It was lead by Atelier YokYok with students from the Superior Art & Design School from Orléans (France ESAD Orléans). The Accordion Arch is visible at the ESAD Orléans until April 19 2019 as part of the Festival Inopiné. The project is part of a research program on modular structures with the ESAD Orléans School. This experimental project is intented to be built in the Château de Chambord’s stables in France. A first week of workshop for design was lead during January 2019 with students of the ESAD. A second workshop phase dedicated to the construction occured at the beginning of April 2019 for the setting up of the first Accordion Arch prototype at scale 1.

The Accordion Arch首先是一个针对木板槽口的研究成果。在1月份开始的工作坊中，学生们可以制作一套大约5种不同方案的模型。以节约材料和简洁细部为指导原则，项目通过增加简单的模块来表现生成空间的不同方式。

The Accordion Arch is first of all, the result of a research work about notches in wood panels. This work lead along January with the students allowed to produce a set of models around 5 proposals. Driven by material and detail saving, the projects represent different ways to generate a space from the addition of simple modules.

介于建筑与设计之间的这一项目关注材料、节点细部、体量之间的关系、木材槽口或堆叠的稳定性、将比例缩减到1：1产生的变化等一系列问题。

At the boundary between Architecture and Design these works question the link with the material, the assembling detail, the volume and the quest for stability by the wood notch or folding, as well as the change from reduced scale to scale 1.

The Accordion Arch由182块22厘米厚的胶合板和890个塑料卡箍构成。借助于胶合板菱形加固槽口插入模块之间来维护自身稳定性和刚性，结构不需要任何螺丝，唯一的节点部件是木材槽口和接缝之间的卡箍。

The Accordion Arch is formed by 182 plywood panels of 22mm thick and 890 plastic clamping collars. It is autostable and rigidified with plywood diamond stiffeners inserted between the modules. The structure doesn’t count any screws and the only details are the wood notches and the seams with clamping collars.
