Building interior wall scaffolding, where the design of the interior floor to the lower surface of the roof (or the height of the gable 1 2 places) of the masonry height in 3If it is less than 6m, it will be calculated according to the scaffolding;The height of the masonry is more than 3When it is more than 6m, it is calculated as a single row of scaffolding.
Stone masonry walls, where masonry height exceeds 1When it is more than 0m, it is calculated according to the external scaffolding.
When calculating the scaffolding of interior and exterior walls, the area occupied by doors, window openings, empty ring openings, etc., is not deducted.
When the height of the same building is different, it should be calculated separately according to different heights.
Cast-in-situ reinforced concrete frame columns and beams are calculated according to double-row scaffolding.
Fence scaffolding, where the height of masonry from the outdoor natural floor to the top surface of the fence is 3If it is less than 6m, it will be calculated according to the scaffolding;The height of the masonry is more than 3When it is more than 6m, it is calculated as a single row of scaffolding.
