<p>The crosspiece sole plate (1) has a bearing surface (32) on the ballast or structure of the ground (41) and includes a continuous mounting wall (3) having a bearing surface (7) and a securing surface (4) that is provided with suitable, endogenous, raised coupling elements (8). The sole plate (1), in the final general configuration thereof and in the solid state thereof, is to be included in a concrete crosspiece (2) or the like having a mounting area (40), such as rails (39). A distribution of cohesive forces is created between the securing surface (4) and the securing surface (5). One such raised coupling element (8) includes a proximal narrowed portion (11), toward the securing surface (4), a distal widened portion (12), and one or more facets (13) extending parallel to, or in an angled manner relative to, the securing surface (4), and said sole plate is characterized by forms, sizes, and distribution of the heterogeneous raised coupling elements (8).</p> |
