Description

Novel attached lifting scaffold

Technical Field

The utility model relates to a scaffold frame field especially relates to a novel attached lifting scaffold frame.

Background

Attached lifting scaffolding (climbing scaffolding) that can climb up or down along a building. This system makes the scaffold technology completely improved: the disassembling and assembling procedures of the scaffold are simplified (the scaffold is used until the construction is finished after one-time assembly), and the scaffold is not limited by the height of a building, so that manpower and materials are greatly saved. Compared with the traditional double-row scaffold, the steel plate punched mesh is adopted as the outer vertical surface of the all-steel lifting scaffold, and the scaffold plate is made of steel pattern steel plates and a turning plate, so that the overhead side-facing operation is as common as indoor. The construction environment is well sealed, high-altitude falling and object striking are avoided, and construction accidents of high-rise buildings are greatly reduced. The all-steel lifting scaffold controls the lifting motion of the scaffold body through a lifting mechanism, and generally has a synchronous control device, an anti-overturning device, an anti-falling device, a load control system and the like to ensure the stability and safety of the scaffold body.

The existing all-steel lifting scaffold is large in types of materials required for installation, complex in specification and model, high in requirement on the construction process of workers, and required to be guided by the constructors during construction. The walkway plate and the off-wall plate are usually welded on site by workers, the efficiency is low, the use safety performance of the off-wall plate is related to the welding quality of the welders, and the use safety of the off-wall plate cannot be ensured. The position of the small bulge of the outer wall of the building is not easy to be processed away from the wall, and the material is usually cut on site to overlap and repair the wall, so that the material cannot be recycled. The whole appearance is poor, and the using effect is not good. The installation positions of the separation wall plate, the turning plate and the walkway plate are fixed, and the complex and changeable conditions of a construction site cannot be met. Meanwhile, the overhanging overlong length of the upper-layer scaffold generates large pulling force on the whole frame body and the building, the safety is low, and the probability of toppling is high.
