21世纪的木材框架
A mix of modern and traditional methods of joinery and assembly creates an engineered timber frame that goes up fast.
概要:New machinery (such as theHundegger K21 CNC multihead machine) can cut framing parts faster than ever, increasing productivity on the job. In this article, a series of photographs details a timber-frame addition in which a crew uses machine-made components and then fine-tunes the joinery before assembling the structure in the field.
In 1976 I worked on my first木构架。我们拆除了一个前时代的房屋框架,将其移至新站点,并将其重建为新房屋。该项目让我迷上了木材框架 - 数十年,之后有500多个项目,我仍然喜欢它。
In the early days, we focused on moving andrestoring old frames, but now the majority of our work is building new frames from scratch, using machinery that our timber-framing forbearers couldn’t have imagined. The increase in productivity has allowed me to grow our company to 30 employees and build dozens of timber frames every year. Our automated methods also mean that our employees—who often have the bad knees and bad backs that come with a lifetime of construction work—can continue their careers much longer than if they were moving and assembling timbers without machinery.
Our most powerful tool is a Hundegger K2i, a CNC multihead machine that cuts the timbers to length and does the majority of the joinery (在行动中看到它). After our team designs thejoinery并告诉机器如何进行切割,我们可以将木材放在一端,几乎完整的框架出现。但是它不能做一切。至少需要用手动工具清理关节。该机器也无法制作大型弯曲零件,因为它们不适合内部。我们用便携式电动工具以及传统的槌槌和凿子制作这些问题和其他问题。回收的木材和框架被手动完全切割。
The photos in this article show a frame we made and assembled for the historic B.F. Clyde’s Cider Mill in Mystic, Conn. The 15-ft. by 24-ft. space, which will be covered with board siding to match the existing barn, is a cider storage room that will hold tanks of fermenting cider. The tanks’ great weight is why the floor is framed with LVL joists. The building is also close to the coast, so it has additional bracing for wind loads. We can help engineers and other specifiers, who often have little experience with timber framing, design their timber-frame structures for almost any residential or commercial application. This frame, which has 115 pieces, took about five days to build in our shop. We delivered it to the job site on an equipment trailer early one weekday. With the help of a local crane operator, our three-person crew lifted the first pieces off the trailer around 9:30 a.m., and we finished assembly around 3 o’clock.
