The fixture between a flat surface (1) and a support framework consists of an under frame (4) perpendicular to the surface (1) and girders (2) supporting the surface (1) and perpendicular to the under frame (4). It consists of a first and second angle plate (5,6) between whose parallel wings (5a,6a) is gripped the surface (1). These wings (5a,6a) of the two angles (5,6) are lodged in recesses (1a,1b) on both the top and bottom faces of the surface (1) and the whole is clamped up as a solid structure by screws.
