Method for assembling a structure for a tool holder and an apparatus comprising said tool holder, and corresponding structure and apparatus

A method for transporting and mounting a tool holder structure by one person alone, said tool holder structure being adapted to receive and move a tool holder for actuation of a tool opposite or against a surface or a wall, said method including the following steps:

• A) selecting one or more set(s) of main structural elements, and optionally one or more complementary set(s) of structural elements, according to the dimensions of the wall or of the surface opposite or against which said structure is intended to be mounted;
• each set having a weight configured to enable one person alone to lift and transport a set,
• B) transporting the set(s) of main structural elements, and optionally the complementary set(s), proximate to said surface or wall;
• C) forming a structural portion by assembling profiled elements together and with endpieces originating from the set(s) selected and transported in steps A and B, by cooperating a male end of a profiled element with a female end of another profiled element or of an endpiece, or vice versa, and securing the whole by securing means of said structural portion;
• D) on a formed structural portion, securing ends of a toothed belt on ends of the structural portion, proximate to or on the endpieces of said structural portion, and mounting a trolley on said structural portion by cooperating the toothed belt with the trolley, the toothed belt and the trolley originating from the set(s) selected and transported in steps A and B;
• E) optionally forming other structural portions if an actuation of a tool is provided for, not only along or against a portion of one single surface or wall, but over or against a surface or wall or over or against several surfaces or walls, and assembling the structural portions together or one or more structural portion(s) with one or more trolley(s);
• F) securing the structural portion(s) at their legs by anchoring means, reversible or not, to said surface or wall, and/or to surfaces or walls adjacent to said surface or wall;
• G) optionally, adding to the structure, thus mounted, complementary structuring means originating from the set(s) selected and transported in steps A and B.
