Steps a quarter turn in prefabricated in elements separated.

摘要

Quarter-turn stairway made of precast concrete in separate elements which are joined together on site. The invention relates to a quarter-turn stairway which is made of concrete and which can be set up by a relatively unskilled workforce, without lifting equipment, special tools, or a string wall. It consists of an end plate (1), two strings (2) and (3), and independent steps which are fixed to one another and also to the ground (4), the floor (5), and the load bearing wall (6) by means of conventional mortar. This stairway is intended in particular for access to a cellar or basement. IMAGE
