In order to facilitate joining together of profile beams (12', 12'') in a cabin frame, use is made of a profile beam (12') having at least one end section which is designed with a cover element (16). The cover element (16) can be folded along a slot (18) between a position in which it exposes an area for joining together between the profile beams (12', 12'') and a position in which it covers a joint in the said area. |
