METHOD FOR LAYING PAVING SLABS Russian patent published in 2022 - IPC E01C15/00 

FIELD: landscape construction and finishing works.

SUBSTANCE: invention can be used in landscape construction and finishing works in the manufacture of paths from paving slabs. The method for laying paving slabs includes the formation of a cushion of two layers of sand-gravel mixture and screenings 10 cm thick, their alignment and compaction. On a flat surface, prepared welded structures are installed, consisting of corners 45×45 and fittings connecting them D=10 of the appropriate length, which depends on the width of the planned path of paving slabs. Then, tracks of the appropriate configuration are formed from the welded structures, while the welded structures are interconnected by metal strip dies, which are placed under the joints of the structures and welded by electric arc welding. Subsequently, screenings are poured into the prepared welded structures, on which paving slabs are mounted. Metal corners with vertical planes keep the extreme rows of tiles tightly laid in welded structures from spreading. The outermost rows of paving slabs are laid with their outer lower faces on clean vertical planes of metal corners, and the rest of their lower surface on a cushion of screenings. The rest of the inner rows of paving slabs are located on the screening pad. Reinforcement and dies from a metal strip are welded to the horizontal planes of metal corners from below, which does not interfere with the installation of tracks. Welded structures are formed from metal corners and fittings. According to exact measurements, segments of metal corners and fittings of the appropriate length are cut off. The reinforcement is welded to inverted metal corners after 1.5-2 m or according to a template from an inverted paving slab laid out on a flat surface, metal corners are laid on the extreme rows, which are welded together with reinforcement of the appropriate length after 1.5-2 m.

EFFECT: simplification of the process of laying paving slabs.
