Timber Fixings

HALFEN Timber Fixing Strap
To secure the position and to prevent lifting due to wind suction the timber beams of flat roofs are put on steel concrete ring beams where HALFEN channels are cast in with flush surface according to their load capacity.
Timber connection straps with hammer head are put in the HALFEN channels, pushed and nailed to the timber beams. HALFEN timber connection straps are a simple, safe and especially quick method of fixing.
HALFEN Rafter Shoe
Instead of concrete upturns used in the past (which required a lot work in view of formwork and reinforcement) the rafter shoes are screwed directly on the HALFEN channels which are cast in the concrete slab with flush surface.
Thus, loads of rafter and collar beam roofs with widths of the rafter from
6 up to 12 cm
and different roof pitches can be fixed with only one type of rafter shoe.
DETAN Rod System
Wide structures of hall binders are increasingly constructed from combinations of wood glue binders with steel tension rods. With their forged fork end and the thin, high-tensile tension rods the DETAN tension rod system is the basis for filigree constructions which meet high architectonic requirements.
