ABSTRACT:
In a method for the production of thermally insulated composite sections a free space (4) formed between at least two metal sections (1,2), held spaced apart, and sealed at the bottom is filled from its open side with an insulating material (10) which at first is in liquid form and then hardens. In order to produce such sections, particularly also those of large size, with the least possible expense for labor and material, and at the same time to achieve the most favorable heat insulation values in the insulating region, solid insulating material layers (12,13) positively and frictionally joining together the metal sections (1,2), and insulating layers (14) hardening with a porous structure are introduced in succession into the free space (4), each layer only partly filling the free space.
The introduction of the solid insulating material layers (12,13) and of the insulating layers (14) is expediently effected with the aid of a plurality of inlet nozzles (16, 17, 18) whose actions are chronologically staggered and which are disposed one behind the other in the working direction (19) of the filling operation, and for the porous insulating layers (14) the same material can be used as for the solid insulating material layers (12,13), a blowing agent which provides the porous insulating layers (14) with their porous structure being contained in the material in the case of the porous insulating layers (14).
