A system for building railings for the roof and balconies of buildings, for staircases, for fencing, for doors etc. using assembled, prefabricated elements divided into two parts of a pole and of the hand rail, an element for the transversal connection-spacer of the poles, with the poles connected in a special position for the reception of the spacer screw. The invention offers the capability of alternative selection of either individual independent decorative elements which can be rotated around their point of connection with the spacers or the hand rail or of integral decorative units produced by casting. In the case of the independent decorative elements, the connection is effected with a prototype joint with a key characteristic being the expansion of blades into grooves-indentations of the pole elements or of the hand rail. In the case of the integral unit of decorative elements the integrated set of decorative elements ends at its lower end in longitudinal bars which penetrate and are screwed at the top and bottom into grooves of the body of the spacer element, which in such case is divided into two parts and closes with a cover after the screwing. |
