Title (EN) WOVEN REINFORCEMENT FRAME FOR CONCRETE STRUCTURES, AND METHODS FOR MANUFACTURING SAME
(FR) CAGE D'ARMATURES TISSÉES POUR OUVRAGES EN BÉTON ET PROCÉDÉS DE FABRICATION
Abstract: front page image
(EN)According to the device of the invention, in order to counter the consecutive disturbances in the disaggregation of the concrete due to Poisson's ratio, the compressed bars are banded by a continuous piece of steel wound into coils (3) that are connected via straight segments (2). The ladders (1), which constitute the basic three-dimensional structural elements, have simple triangular, rectangular, or polygonal cross-sections. Said basic units can be assembled either by bars or, in order to increase the ultimate strength, by ladders (5) having axes that intersect the mid-plane.
(FR)Selon le dispositif pour s'opposer aux désordres consécutifs au désagrégeage du béton sous influence du coefficient de Poisson, les barres comprimées sont frettées par un acier continu enroulé sous forme de spires (3) reliées par des segments droits (2). Les échelles (1), qui constituent les éléments structurels élémentaires tridimensionnels, sont de sections simples triangulaires, rectangulaires ou polygonales. Ces ensembles élémentaires peuvent être assemblés soit par des filants, soit pour renforcer la résistance à la rupture par des échelles (5) d'axes sécants avec le plan médian.
