Abstract

L’invention concerne un dispositif de fixation d’échafaudage pour fixer un échafaudage disposé sur un cadre de base. Le dispositif de fixation d’échafaudage comprend: un corps principal comprenant une plaque de pression pour presser la surface supérieure de l’échafaudage; un élément de crochet dont une première extrémité comporte un crochet pour maintenir le cadre de base, et dont l’autre extrémité comporte un arbre à cames agencé verticalement sur le crochet; et un élément de came qui est agencé de façon à pouvoir tourner autour de l’arbre à cames, et dont un côté est en contact avec et est supporté par une surface du corps principal. Lorsque l’élément de came tourne, le crochet est pressé et déplacé en direction d’une première surface du corps principal et vers la plaque de pression. Le dispositif de fixation d’échafaudage selon la présente invention fixe l’échafaudage sur le cadre de base par un système à une seule touche en utilisant l’élément de came, réalisant ainsi facilement l’installation et l’enlèvement de l’échafaudage. Le dispositif de fixation d’échafaudage selon la présente invention peut être utilisé de façon répétée pour réduire les coûts, et peut disposer des échafaudages avec un espacement régulier de manière à parvenir à une standardisation de l’installation d’échafaudages.
