Here's a father and son demonstrating its construction in their backyard, without using a single tool:

这是一个父亲和儿子在他们的后院演示它的建设，没有使用一个单一的工具：

As you can see they've used no fasteners, since the structure is designed to support itself. But in da Vinci's original design, notches were meant to be cut into the timbers to add greater security to the structure.

正如你所看到的，他们没有使用任何紧固件，因为结构的设计是为了支持自己。但在芬奇最初的设计中，缺口是为了在木材上切割，以增加结构的安全性。

That was at an event last year celebrating traditional carpentry. (The folks you see wearing black hats and vests have donned traditional German builders' garb.) Incredibly, the 10-meter-span structure was assembled by eight apprentices and two masters in about ten minutes! Here's how they did it:

那是在去年庆祝传统木工的活动上。(The你看到的那些戴着黑帽子、穿着黑背心的人，都穿着传统的德国建筑工人的服装。）令人难以置信的是，这座10米跨度的建筑在十分钟左右的时间里，由八名学徒和两名大师组装而成！他们是这样做的：
