SET OF HEAT NON-INSULATED SECTION BEAMS WHICH CAN BECONVERTED TO HEAT INSULATED SECTION BEAMS

摘要

The set can be used for window and door frames in civilengineering. It converts cold treated (1,2,3,4,5 & 6) into heattreated (10,20,30,40,50 & 60) profile beams. Each profile beamcontains one element of internal steel profile beam (7) and oneelement of external steel profile beam (8) interconnected by meansof connecting walls (9) containing deformable teeth (11) andremovable strips (12). The elements of the internal and externalprofile beams (7 & 8) are supplied with longitudinal indentations(28) suitable to receive insulation profile elements (29) in them.The element of the external profile beam (8) contains at least onesupporting rib (21) connected to a connecting dovetail part (23)drawn from the external side in such a way that a chamber (9) foraeration and collection of water and condensate is formed.
