System for a roof construction, and an eave piece

Abstract

An eave piece, as well as a system for a roof construction, comprising: an eave piece which is prefabricated and intended to be fixed as an extension to a roof beam, which roof beam is substantially horizontal or inclined when installed in the use position; and a front beam which is prefabricated, substantially horizontal, intended to be placed transversely with respect to the roof beam, and configured to support the eave piece and thereby also the roof beam. The lower surface of the eave piece is provided with a recess, in which at least the top surface of the front beam can be received. Structures to be placed against each other are provided on the bottom of the recess on one hand and on the top surface of the front beam on the other hand, their form following at least partly the shape of a circular arch. The structures are, for the installation, also configured to allow use positions of the eave piece with a varying inclination with respect to the front beam.
