<p>A metal fitting for forming an end connection of a wooden beam, such as a roof beam or purlin, to a supporting structure, which may also be a wooden beam, such as a main beam or truss, characterized by a web having opposite bearing surfaces, one bearing surface engaging a surface of the supporting structure and the other surface engaging the end of the beam. The one surface has an arrangement, such as a supporting flange extending perpendicular thereto, for mounting the fitting on the support structure. To mount the beam, the fitting has at least one leg extending perpendicular from the other bearing surface having a constant thickness and being provided with a groove-like attenuation to separate the leg into a supporting portion and a free end portion, which free end portion has openings for receiving fastening elements. The attenuation prevents the transfer of forces extending parallel to the web being applied to the free end portion from being transmitted to the web, but allows tensile forces to be transferred to the web of the fitting.</p> |
