Superimposed member for roof openings of buildings.

摘要

A superimposed member for roof openings of buildings consists of an upper portion (12) and a lower portion (6) which is connected to this and surrounds a horizontal or inclined roof opening (4) and which is in the form of a base bounding the roof opening by its inside. Disposed between the under side of the upper portion and the upper side of the lower portion is a horizontal arm (16) of an angle-section bar member (13) which changes over into a downwardly directed arm (17) for securing a flashing (9) raised out of the plane of the roof to the outside of the lower portion (6) in a sealing manner. The horizontal arm (16) is simultaneously held in sealing engagement with the under side of the upper portion (12). A reliable sealing between upper portion (12) and lower portion (6) and between lower portion (6) and the flashing (9) is achieved with reduced expenditure on material and mounting and cold bridges in the transition region from the lower portion (6) to the upper portion (12) are avoided.
