A, building the upper wall outside pick out more than 1.5 m, according to the exterior of the upper edge is concave and convex length times building scaffolding, the total height calculation area;

Bottom wall retreat into parts in accordance with the vertical projection area of the palisade structure according to the height of the corresponding single scaffold is calculated. Second, when the building's exterior line building scaffolding set-up height of less than 15 m, press computation of single scaffold; More than 15 m, calculated on composite scaffold.

Three, the daylighting of the recessed part well: when the outside width (exterior structure spacing) 3.5 m or less, according to the concave part into the medial wall vertical projection area of single row scaffolding calculation, daylighting well regardless of the presence of the beam, are calculated with the exterior wall composite scaffold; When the outer width (3.5 m, the exterior structure spacing) according to the concave part into the medial wall vertical projection area of the m2 to calculate comprehensive scaffolding, light well outside the mouth of coupling beam, computing composite scaffold, along with the exterior wall without even the beam do not calculate scaffolding.

Four, stone masonry regardless of external walls, height more than 1.2 m, calculating a composite scaffold;

Wall thickness is more than 40 cm, calculating a composite scaffold and a single row scaffolding.

Five, when more than 2 m of large equipment foundation, according to its perimeter multiplied by the form of highly in terms of area (m2) single row scaffolding.

Six over roof, roof parapet height of 1.2 m, can be calculated on the inside vertical projection area of the m2 single row scaffolding. Seven, when the wall height more than 1.2 m, according to the calculated by vertical projection area of the m2 single row scaffolding, single wall illuminative calculated on one side, calculated on double-sided double-sided decoration.
