A stabilizing collar for a concrete saw blade provides a rigid blade structure for smoother cutting operations, particularly in partially cured concrete. A pair of the present collars (10a, 10b) are secured to the blade shaft on each side of the blade, clamping the blade securely therebetween. Each collar has a slightly recessed central area and a raised toroidal rim therearound. Clamping the blade and collar assembly tightly on the shaft, compresses the recessed areas and clamps the rim portions of the collars tightly against the blade at some distance outward from the shaft, thereby providing a rigid assembly and essentially eliminating lateral vibration and flexing of the blade. This enables an otherwise conventional concrete saw to be used for cutting "green" concrete, i. e. relatively soft concrete which has only partially cured.

L'invention concerne un collier de stabilisation destiné à une lame de scie à béton possédant une structure de lame rigide permettant des opérations de découpe dans du béton plus tendre, notamment dans du béton partiellement durci. Une paire de ces colliers (10a, 10b) sont fixés à l'arbre de lame de chaque côté de la lame, pinçant la lame de façon sécurisée entre eux. Chaque collier possède une zone centrale sensiblement en retrait et une rainure toroïdale en relief sur son pourtour. Le pinçage serré de la lame et de l'ensemble de collier sur l'arbre, comprime les zones en retrait et pince étroitement les parties de rainures des colliers contre la lame à une certaine distance externe de l'arbre, fournissant ainsi un ensemble rigide et éliminant sensiblement la vibration latérale et la flexion de la lame. Autrement dit, ceci permet à une scie à béton conventionnelle d'être utilisée en vue de couper du béton <= frais >= à savoir, relativement mou, lequel a été seulement partiellement durci.
