Abstract: Mounting fixture (1) for construction panels (2), consisting of an H-shaped profile comprised of a bottom plate (3), a midriff (4) and a front plate (5), whose bottom plate (3) and front plate (5) are mutually essentially parallel by the joining midriff (4), and that construction panels are intended to be attached to the space between the bottom plate (3) and the front plate (5). The midriff (4) and the front plate (5) are with evenly spaced intervals recessed so that protruding sections (6) with intermediate recesses (7) are formed in the mounting fixture's longitudinal length, said protruding sections (6) consisting of the remaining sections of the midriff (4) and the front plate (5), and that each respective recess (7) is intended to, after the construction panel's insertion, form a space for joint compound for joining and sealing of the panels.
