Abstract

The HexBox Canopy demonstrates a new "plug & play" system for the rapid on-site assembly and disassembly without formwork of a segmented timber shell, consisting of relatively inexpensive, prefabricated hexagon-shaped boxes made from plywood plates. With 1531 timber segments making up 201 boxes, the HexBox shell is made exclusively of plywood components without the addition of any kind of metal fasteners for the main load-bearing structure. The major novelty is the wood-only connections between the box components, which are produced from cut-off waste material resulting from the cutting of the main plates of the structure. These connectors are inspired by traditional wedge joints, which were a smart and common method in handcrafted carpentry and cabinetmaking. Rather than attempting ultra-precisely fabricated elements, the wedges allow assembling box-like segments even when there are small imprecisions. Additionally, these joints allow for pulling and forcing the boxes together, closing gaps between the elements which may occur during assembly. Another key aspect is the introduction of an innovative technique that allows for the simple and safe 1K PUR adhesive joining of thousands of miter joints with individual dihedral angles. Conventional clamping tools are indeed designed for orthogonal miter joints and could therefore not be used here.

Hexbox雨棚:带硬木楔形接头的分段木板壳
HexBox Canopy展示了一种新的“即插即用”系统,用于快速现场组装和拆卸,无需模板的分段木壳,由相对便宜的由胶合板制成的预制六边形盒子组成。HexBox外壳由1531个木片组成201个盒子,完全由胶合板组件制成,没有为主要承重结构添加任何类型的金属紧固件。主要的新颖之处在于箱体部件之间的连接是纯木材的,这些部件是由切割结构主板产生的废弃材料制成的。这些连接器的灵感来自传统的楔形接头,这是手工木工和橱柜制作中一种智能而常见的方法。而不是尝试超精密制造的元素,楔形允许组装盒状的部分,即使有小的不精确。此外,这些接头允许将箱体拉紧在一起,从而缩小组件之间可能在组装过程中出现的间隙。另一个关键方面是引入了一种创新技术,该技术允许简单安全的1K PUR粘合剂连接数千个具有单独二面角的人字接头。传统的夹紧工具确实是为正交人字接头设计的,因此不能在这里使用。
