Assembly plate used in the production of a corner element for heating pipes and cables comprises a wedge which is lower than the depth of the groove

摘要

Assembly plate comprises a wedge (16) which is lower than the depth of the groove (13). The wedge is made from the material of the core (11) and is connected to a covering layer (12) in the region of a groove base (21). An independent claim is also included for a method for the production of a corner element made from an assembly plate. Preferred Features: The wedge is 5-20 %, preferably 10 % of the depth of the groove. The wedge has a triangular cross-section. The groove walls have an outer section (22, 23) and an inner section (24, 25) each having a different inclination opposite the covering layer.
