The base part has two elongated, plate-shaped profiles (P) with a longitudinal side (1) and another longitudinal side, where each of the profiles has two hollow chambers formed as hollow cylinders. Wall thicknesses of the hollow chambers are same. The hollow chambers have a common wall part, and a locked connecting element provided at the longitudinal sides is the part of walls of the hollow chambers. A gripping groove (G) is formed at a lower side (3) of each profile as a component of the walls of the hollow chambers, where the profiles are formed as wooden cores with metallic surfaces. An independent claim is also included for a method for manufacturing a frame locked base part. |
