Abstract

L'invention concerne un élément de construction pour l'érection de parois dans des constructions de bâtiments, en particulier en tant que cloison non porteuse, constitué de deux nappes de treillis métalliques (1, 2) soudées et parallèles, de plusieurs baguettes d'entretoisement (7, 71) reliées aux deux nappes de treillis métalliques et maintenant ces dernières à une distance mutuelle prédéterminée, d'un corps isolant (8) qui est traversé par les baguettes d'entretoisement et dont les faces de recouvrement sont agencées parallèlement aux nappes de treillis métalliques et à une distance prédéterminée de ces dernières. L'élément de construction est en outre constitué de plaques (10, 11) enveloppant les deux nappes de treillis métalliques. L'invention vise à ériger des parois dans des constructions de bâtiments, de préférence en tant que cloison non porteuse. A cet effet, une plaque constituée de matériau de construction léger, de préférence en plâtre renforcé par des fibres de verre, est appliquée respectivement sur les deux nappes de treillis métalliques, cette plaque étant contiguë au corps isolant et entourant les nappes de treillis métalliques respectives.
