The staircase has treads fastened in the wall and to balusters, which are fastened to and carried by a handrail of rigid material. Rod-shaped tread supports (4) are anchored with one end in the brickwork (7) of a wall. They extend under the treads and permanently or removably fastened to them. The opposite ends of the tread supports are each fastened to a baluster (2). The tread carriers are formed by tubular sections with a circular or rectangular profile made of e.g. iron or iron alloys. The carrier ends are anchored in the walls via dowels or hardening/polymerising materials. |
