摘要

A frontal support -anchor housing, comprising essentially a simple section of the open -profile shape combined with the anchor rail, is characterised by the fact that the coupling of the shape (1) with the anchor rail (3) is achieved in a series system by means of an anchorage element established in the final part of the shape (1) and having an opening or cut in which the end section of the anchor rail (3) is located,equipped with a blocking -pushing element, the diameter of the hole or the cut -out width being greater than the external diameter of the anchor bar (3) but less than the minimum cross -section dimension of the blocking -pushing element. The method of securing the ceiling in the articulated section of the wall -mounted superstructure by means of an articulated support -anchor housing is that an artificial ceiling is constructed on the section covered by the circumference or fall of the ceiling -stones, the essential element of which is the superstructure in the shape stations (1),one end supported on the ceilings of a mechanized wall section (10),and the other end connected to the stern of an anchor built into the ceiling or deck.
