A jukkenkap is a roof structure in which the posts of the bent are set at a slant inwards. Such a slanted post is called a juk (trestle or bent-leg). By slanting the posts, more free, usable height is created under the roof than with an upright bent. The construction was much used where large spans were needed.
Build-up
- Juk (trestle) — the slanted post that carries the roof load down to the wall or floor
- Trestle tie-beam — the cross-beam on top of the trestle that links the trestles together
- Block sill (blokkeel) — the piece by which the trestle is seated on the wall plate
- Brace (korbeel/karbeel) — a strut that stiffens the angle between trestle and tie-beam
Application
The jukkenkap was common in farmhouses, barns and other buildings needing a large, undivided space, such as a bay for the harvest or livestock. The slanted trestles left more usable height for storage.
Points to note
- In repair, understanding the joints (block sill, brace, mortise-and-tenon) is vital to transfer the loads correctly
- You still meet the construction in historic rural buildings
