Anti-tilting load-bearing scaffold

Technical Field

The invention relates to the technical field of building construction, in particular to an anti-inclination load-bearing scaffold.

Background

The scaffold is a working platform which is erected for ensuring that each construction process is smoothly carried out. The scaffold is divided into an outer scaffold and an inner scaffold according to the erected positions; the scaffold can be divided into a wood scaffold, a bamboo scaffold and a steel pipe scaffold according to different materials; the scaffold is divided into a vertical rod type scaffold, a bridge type scaffold, a door type scaffold, a suspension type scaffold, a hanging type scaffold, a lifting type scaffold and a climbing type scaffold according to the structural form.

The existing movable scaffold is a scaffold with rollers at the bottom, is usually used for interior decoration or exterior wall decoration with the height of not more than 10 meters, and has small and exquisite structure and convenient movement, so that the application is quite wide. When the existing movable scaffold is used, after the scaffold is moved to a proper position, a user usually needs to lock the rolling wheels, and then supports the rolling wheels by using weights such as bricks and the like to prevent the scaffold from moving. However, when a user carries some operating tools to climb on the top of the scaffold, the scaffold is prone to shaking due to the heavy weight of the top of the scaffold, and particularly when the ground is not flat enough or has a depression, the scaffold is prone to rollover, so that potential safety hazards are brought to the user.
