METHOD OF PRODUCTION OF THIN-WALLED SELF SUPPORTED STONE ROSETTES OR ANY SELF SUPPORTED FLAT THIN-WALLED STONE STRUCTURES MADE BY CUTTING FROM STONE SLABS

摘要

The production procedure of thin-walled, self-supported stone rosettes (2), i.e. any other thin-walled flat self-supported stone structure obtained by cutting out of natural stone slabs, shall allow that they remain self-supported even in horizontal position and bear a calculated useful load with point supports (1) or with linear peripheral supports. The production procedure comprises the realisation of the groove (5) in the stone slab, pouring of glue in the groove, inserting, in that groove filled with glue, a previously calculated steel flat bar (6), that aligns the axes of elements of the future thin-walled structure (2), a rosette, and ulterior cutting of the desired stone structure out of the prepared stone slab. Cutting lines (2a) (2b) are just a few millimetres away from the left and right sides of the cross-section of the steel flat bar supporting structure (6).
