A framing member (100) incorporates a series of web slots (103) along a portion of the member (102) that are expanded through the process of manufacture. The expansion of the web slots (103) creates voids and metal web elements in the webbed portion (a1, a2) of the member, which can be a stud. The voids (104) created during the expansion process can become the voids (104) for running wiring, plumbing and heating ducts. The web elements (102) can be designed to minimize thermal transmission from the exterior to the interior of a wall including the member as well as provide adequate structure properties required from the structural member. The expanded slots (103) allow the part to enlarge without increasing the amount of raw material and therefore substantially reducing the cost to manufacturer.
L'invention porte sur un élément d'ossature dont une des parties de l'âme comporte une série de fentes élargies pendant le processus de fabrication. L'élargissement des fentes crée dans l'âme des vides, et des parties métalliques d'âme pouvant servir d'entretoises. Les vides ainsi créés peuvent servir à faire passer les câbles, et les tuyaux sanitaires et de chauffage. Les éléments d'âme peuvent être conçus pour réduire les transferts thermiques entre l'extérieur et l'intérieur d'une paroi comportant l'élément d'ossature tout en présentant les caractéristiques adéquates requises d'éléments structuraux. Cet élargissement des fentes, qui n'implique pas d'augmentation du volume des matériaux constitutifs, permet une réduction substantielle des coûts de fabrication.
