Production method for a finished panel, like a door wing, for closing an opening in the exterior of a building, and the finished door

摘要

#CMT# #/CMT# The method involves integrating inserts (42, 43) into orifices (44, 45), where the inserts have an open face and delimit an inner volume to house hinge elements and lock blocks (34-36). The inserts are immobilized with respect to a frame and covering sheets in a position where the inserts isolate the orifices with respect to an inner volume of a panel. The inner volume of the panel is filled by injecting a foaming mixture into the panel volume, where the mixture forms a rigid foam, by polymerization, adapted to be connected to the frame and covering sheets by adhesion. #CMT# : #/CMT# An independent claim is also included for a finished panel comprising a frame. #CMT#USE : #/CMT# Used for forming a finished panel such as an opening frame of a door, for closing an outer opening of a building. #CMT#ADVANTAGE : #/CMT# The method permits to obtain the panel having wide personalization possibilities in an industrial manner with optimized cost in terms of manpower, and having improved qualities of thermal insulation and mechanical resistance. The method permits to introduce a counter-form of dimensions, to the inserts, conjugated with the inner volume of the inserts in order to avoid the deformations of the inserts resulting from pressure exerted on the inserts during the injection or expansion of the foaming mixture. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of an opening frame. 9 : Crosspieces 28 : Covering sheet 34-36 : Lock blocks 42, 43 : Inserts 44, 45 : Orifices #CMT#POLYMERS : #/CMT# The inserts can be made of polyolefin or polytetrafluoroethylene.
