Abstract

Elément de coffrage métallique, pour la formation de joints verticaux lors de la construction de parois moulées par la méthode des tranchées ouvertes, dans laquelle les parois en béton sont coulées section par section dans des tranchées longitunales ouvertes. L élément est caractérisé par un corps prismatique ayant au moins deux surfaces latérales principales parallèles et par un bossage en forme de coin saillant de l'une de ces surfaces et perpendiculaire à la base du corps prismatique L'invention permet de réaliser des joints verticaux de section plus réduite et de plus grande résistance que ceux réalisables jusqu'à présent.Metal shuttering element, for the formation of vertical joints during the construction of diaphragm walls by the open trench method, in which the concrete walls are poured section by section in open longitudinal trenches. The element is characterized by a prismatic body having at least two parallel main side surfaces and by a wedge-shaped boss projecting from one of these surfaces and perpendicular to the base of the prismatic body The invention allows vertical joints of smaller section and greater resistance than those achievable so far.
