Pipe penetration for a tubular element through at least one surface section of a building

Abstract

Pipe penetration for a tubular element through at least one surface section of a building, in particular a flat roof, with at least two attachment pieces each enclosing the tubular element, characterized in that each attachment piece (2, 3) is frustoconical and has an upper and a lower bearing surface, wherein an upper attachment piece (2) is attached to the element (1) with its upper bearing surface (5) in a rotationally fixed manner and its lower bearing surface (6) is angled to the upper bearing surface (5), wherein a lower attachment piece (3) is attached to a flange (4) with its lower bearing surface (7) in a rotationally fixed manner and its upper bearing surface (8) is angled to the lower bearing surface (7) at the same angle as the angle of the upper attachment piece (2), and both attachment pieces (2,3) are connected to each other and to each other in a rotatable manner via the lower support surface (6) of the upper attachment piece (2) and the upper support surface (8) of the lower attachment piece (3).
