Common safety hazards of ground-type scaffolding

CHANGSHA, China - Oct. 28, 2024 - PRLog -- 1. Foundation treatment of ground-type scaffolding
(1) The foundation of the erection frame must be flat and solid, with sufficient bearing capacity; there must be no water accumulation in the erection site.
(2) During the erection, drainage ditches or other drainage measures should be set up on the outside and periphery of the scaffolding.
(3) The support pole pads should meet the bearing capacity requirements, and the pad thickness should not be less than 50mm.
(4) The support pole pads should meet the bearing capacity requirements, and the bottom elevation of the base should be 50~100mm higher than the natural floor.

2. Sweeping rods for ground-type scaffolding
The frame must be equipped with longitudinal and transverse sweeping rods. The longitudinal sweeping rod must be fixed on the pole no more than 200mm from the bottom end of the steel pipe with right-angle fasteners. The transverse sweeping rod must be fixed on the pole close to the bottom of the longitudinal sweeping rod with right-angle fasteners.

3. Wall ties for ground-type scaffolding
The wall ties should be arranged close to the main node and the distance from the main node should not be greater than 300mm. The wall ties of double-row steel pipe scaffolding should be connected to the inner and outer rows of poles.
For double-row scaffolding with a height of more than 24m, rigid wall ties are also used to reliably connect with the building structure. The vertical spacing of the wall ties should not be greater than the floor height of the building, and should not be greater than 4m, and the horizontal distance should not exceed 6m. Wall ties must be set at both ends of the open double-row scaffolding.
Scissor braces and wall ties must be erected and dismantled simultaneously with the external scaffolding. It is strictly forbidden to erect them later or dismantle them first.
