Description

LIFTING METHOD OF INTEGRATED ATTACHED LIFTING SCAFFOLD Technical Field The present invention relates to the technical field of all-steel integrated outer protective frames for decoration construction of main bodies and external walls of high-rise or super high- rise buildings, and in particular to an integrated attached lifting scaffold and a lifting method thereof.
Background Scaffolds mean various brackets erected on a construction site for workers to operate and realize high-altitude operation. As a common term in the construction field, the scaffolds are mainly used on the construction site for external walls, internal decoration or high-rise areas that cannot be directly constructed. The scaffolds are generally made of bamboos, wood, steel pipes or synthetic material. At present, the scaffold is also used as a template in some projects. In addition, the scaffold is also widely used in the fields of advertising industry, municipal administration, traffic roads and bridges and mines.
Back to the construction field, in the current high-rise building construction, external wall scaffolds mostly adopt lifting scaffolds. External scaffolds are various brackets erected on the construction site for the workers to perform peripheral construction operation and realize peripheral protection, and are used on the construction site on the external wall or high-rise areas that cannot be directly constructed for the construction personnel to work up and down or to install safety nets outside for protection and high-altitude installation of components.
A lifting component below the external scaffold is assembled by a plurality of rods and a plurality of bolts, and is complicated in assembly, labor-intensive and easy to wear. Upper and lower longitudinal horizontal rods of a horizontal support truss are welded together with vertical rods and diagonal supports into a whole, which is poor in practicability and inflexible and consumes steel materials. A lifting mechanism adopts an upside-down electric hoist, and each layer of lifting requires manual handling of a layer of electric hoist, which consumes labor; and the existing lifting scaffolds cannot ensure the carrying capacity of the force transmission structure of the lifting mechanism, resulting in poor structural stability of the lifting point position of a scaffold body, and cannot ensure the provision of sufficient operating space for the lifting mechanism, resulting in deformation and instability due to concentrated and uneven forces on one side of the guide rail. Therefore, for the above problems, a scaffold is proposed, which can ensure the carrying capacity of the force transmission structure of the lifting mechanism, improve the structural stability of the lifting point position of the scaffold body, and ensure enough operating space of the lifting mechanism, to make the force on one side of the guide rail uniform and avoid the problems of deformation and instability of the scaffold body.
