Collar beam cable roof components - are used in prefab house and have beam form-locked inside and outside panels protruding and recessed opposite ways

摘要

Roof elements consist of individual beams with weatherproof inside panels form-locked on underside and with a rafter or collar beam on one transverse edge, and fitting beam on an opposite edge. The gable roof is entirely made of prefab components. The outside panels (36) have edges protruding as far as the beam, while inside ones are correspondingly recessed, on one side, and vice-versa on the other side. The gable elements protrude beyond the outside transverse edges of the valley bottom elements and gable. The outside panels have top battening for a roof covering. Elements are tough but light enough for transport and easy crane handling, even as combined folded units.
