Abstract

Pour un élément de coffrage comprenant deux panneaux de coffrage reliés par l'intermédiaire d'entretoises (Q), il est proposé de prévoir, au moins dans les entretoises (Q), un trou longitudinal traversant qui est obturé de façon que le matériau de remplissage placé entre les panneaux ne puissent entrer dans ledit trou. Lors de la construction d'un mur au moyen de tels éléments de coffrage, des éléments de stabilisation, tels que des rails de redressement (RS), peuvent être maintenus et tendus au moyen d'éléments de liaison (G) qui traversent le mur en passant par lesdits trous longitudinaux. Les éléments de liaison (G) peuvent facilement être retirés. Les éléments de coffrage présentés sont, de préférence, constitués de panneaux de coffrage fabriqués séparément et d'entetoises (Q) introduites dans lesdits panneaux.
