Abstract

Selon l'invention, un dispositif équipé d'un contrepoids pour le levage rapide d'un panneau de mur en BP présente la structure suivante: une poutre (1) en acier en forme de H et une poutre (3) en acier de contrepoids sont respectivement soudées à deux extrémités d'une poutre principale équilibrée (2) en acier. Des premières pattes (4) de levage en acier sont respectivement soudées symétriquement à deux côtés d'une partie médiane sur la poutre principale équilibrée (2) en acier. Des secondes pattes (5) de levage en acier sont respectivement soudées symétriquement à deux côtés d'une partie d'extrémité de la poutre (3) en acier de contrepoids sur la poutre principale équilibrée (2) en acier. Un trou servant au levage est pratiqué sur la seconde patte (5) de levage en acier. Un contrepoids (6) est monté au-dessous de la poutre (3) en acier de contrepoids. Quatre câbles (7) en acier sont reliés respectivement aux deux premières pattes (4) de levage en acier et aux deux secondes pattes (5) de levage en acier, sont ensuite reliés l'un à l'autre en un ensemble, et sont reliés à une grue externe sur camion. Le panneau de mur en BP est fixé à un point de levage de la poutre (1) en acier en forme de H, et est relié à la section de contrepoids et à la patte de levage sur la section médiane de la poutre principale équilibrée (2) en acier au moyen du câble (7) en acier. La grue sur camion est reliée au câble (7) en acier, soulève des panneaux de mur en BP à un moment donné, et monte le panneau de mur en BP dans une position de montage de panneau de mur en BP présentant une structure en porte-à-faux. Le dispositif de levage facilite la construction, est sûr et fiable, et surmonte efficacement la difficulté de montage d'un panneau de mur en BP sur une structure en porte-à-faux.
