Freestanding modular structure for the construction of elevator shafts

摘要

1. Self-supporting modular structure for the construction of elevator shafts; characterized by comprising: - vertical uprights, polygonal arrangement; formed, each, by several tubular sections of equal section, having at one end an appendage recessed for coupling aligned with the straight tubular profile and, on two adjoining faces, pairs of lateral flaps arranged in two planes vertical and provided with a horizontal through-holes; - a closing panels, arranged between the standoffs for forming a side closure walls of the structure, except for those corresponding to the entrances to the lift areas. - transverse profiles arranged horizontally between uprights consecutive and having first ends horizontal holes for mounting screwed into the side flaps of the tubular profiles of the uprights, defining said horizontal profiles perimetric rings spaced vertically along the uprights and second vertical holes interdistanciados for mounting fasteners and the enclosure panels, - support pieces of elevator guides intended to be fixed on at least one of the transverse profiles. 2. Structure according to claim 1, wherein the cross sections for receiving fixing the support pieces of elevator guides have a third intermediate horizontal holes for screw mounting said support pieces. 3. Structure according to claim 1, wherein two of the pairs of side flaps hollow sections are arranged in correspondence with the opposite ends of said tubular profiles. 4. Structure according to claim 3, characterized in that the pairs of side flaps defined on the facing ends of the consecutive tubular sections are fixed by means of respective flanges bolted to ensure retention of said hollow sections in the coupling position. 5. The structure of any of claims 1 and 2, characterized in that the support members of the lift guides comprise: a base plate provided with elongated holes for positional adjustment in the lateral direction for screwing on the mounting cross profiles; a second plate fixed by screws on the base plate and projecting frontwards one leg for fixing the guides of the elevator. 6. Structure according to claim 5, wherein the second plate has a vertically elongated mounting holes for positional adjustment for fixing bolted to the base plate. 7. Structure according to claim 5, characterized in that the support leg guides has a horizontally elongated mounting holes for positional adjustment of the device guides, distancing them in varying degrees of cross sections of the structure.
