Title (EN) A METHOD AND MACHINE FOR LEVELLING CONCRETE WHEN CASTING LARGE CONCRETE AREAS
(FR) PROCEDE ET MACHINE DE NIVELAGE DU BETON LORS DU BETONNAGE DE SURFACES ETENDUES
Abstract:
(EN) A method for levelling and smoothing concrete when concreting large areas. According to the method a machine which is so constructed that it floats lightly even on highly fluid concrete mass and thus normally exerts a very low surface pressure against the substratum, is caused to move over the surface of the concrete while smoothing and levelling the same as a result of rolling motion between the surface and a belt of the machine in contact therewith. The smoothing or levelling effect of the belt can be amplified by vibrating a plate supporting the belt. The concrete may also be subjected to vacuum treatment at the same time as levelling or smoothing the concrete. The invention also relates to a machine for carrying out the method.
(FR) Procédé de nivelage et de lissage du béton lors du bétonnage de surfaces étendues. Le procédé utilise une machine construite de manière à flotter légèrement même sur une masse de béton très fluide, en exerçant normalement une très faible pression de surface sur le substrat, et qui se déplace sur la surface du béton tout en le nivelant et en le lissant à la suite du mouvement de roulement entre la surface et une bande de la machine en contact avec la surface. L'effet de lissage ou de nivelage de la bande peut être amplifié en faisant vibrer une plaque supportant la bande. Le béton peut également être soumis à un traitement sous vide en même temps qu'il est nivelé ou lissé. L'invention se rapporte également à une machine permettant d'appliquer ce procédé.
