Abstract (en)
The frame of the lighting cupola obtained by the method is formed from a first plastic skin 9 intended to constitute the internal wall of the main body of the frame, from a filling material 10 over this skin, from another plastic skin 8 which constitutes the external wall of the main body of the frame, the upper part of this skin returning towards the centre in order to form the upper horizontal border 11 of the main body. In addition, an independently prefabricated framework 6, constituting the shaped rim, is joined in a fixed manner to this border. Application to lighting cupolas and smoke outlets. <IMAGE>
