How to Calculate Exterior Wall Scaffolding Area?

The height of the scaffolding of the external wall of the building is calculated from the designed outdoor floor to the cornice (or the top of the parapet); The quantity of work is calculated according to the length of the outer edge line of the external wall (the wall stack with a protruding wall width greater than 240mm, etc., calculated according to the size shown in the figure and incorporated into the length of the external wall), multiplied by the height and calculated in square meters.

If the masonry height is less than 15m, it shall be calculated as a single row of scaffolding; When the height is more than 15m or the height is less than 15m, but the exterior wall doors, windows and decorative area exceeds more than 60% of the surface area of the exterior wall (or the exterior wall is a cast-in-place concrete wall or a lightweight block wall), it shall be calculated as a double row of scaffolding; When the height of the building exceeds 30m, it can be calculated according to the double-row scaffolding of the section steel lift platform according to the project situation.

The independent column (cast-in-place concrete frame column) is added according to the perimeter of the structure shown in the column diagram, multiplied by the design column height in square meters, and the single-row external scaffolding project is applied. Cast-in-place concrete beams and walls are calculated according to the height between the upper surface of the designed outdoor floor or floor slab and the bottom of the floor slab, multiplied by the net length of the beam and wall in square meters, and the double-row external scaffolding project is applied.

1) Outer scaffolding.

The scaffolding is calculated in square meters (m2) according to the vertical projection area of the wall, and the opening and empty area of doors and windows are not deducted. All kinds of masonry masonry with a masonry height (except for those specified in the quota) above are required to calculate scaffolding. (2) The vertical projection area of the exterior wall scaffolding is calculated by multiplying the length of the outer wall by the top height from the outdoor ground to the center line of the wall.

Interior wall scaffolding.

The vertical projection area of the inner wall is multiplied by the net length.

The net height of the interior wall is calculated, and the height of 1 2 shall prevail if there is a gable.

The outer scaffold is calculated according to the outer edge line of the external wall, and the height is calculated from the design outdoor ground to the wall height shown in the figure, and when the actual outdoor ground is lower than the design ground, it should be backfilled and tamped before erection, and no additional addition. The wall buttress with the outer width of the protruding wall within 24cm, the chimney attached to the wall, etc., is not counted as scaffolding, and when the protruding width exceeds 24cm, it is calculated according to the size and length shown in the figure, and is incorporated into the engineering quantity of the outer scaffolding; If there is a balcony on the exterior wall, the width of one side is calculated for each balcony, and only one side is counted for the two balconies connected together, which is included in the length of the exterior wall, and is calculated in square meters by the height of the exterior wall. Got it.

Summary. Hello, the above questions will be answered by me. The outer scaffolding is erected according to the perimeter of the outer frame of the building x the erection height.

Calculation formula: outer scaffolding area = [(total length of building + erection width x2) + total width of building + erection width x2] x2x erection height + erection length with protruding parts or indentation x erection height. 1. The exterior wall scaffolding is calculated from the planned outdoor floor to the cornice, and the engineering quantity is calculated according to the length of the exterior wall edge line multiplied by the height.

2. When the building height is less than 15 meters, it is calculated according to the single-row scaffolding, more than 15 meters or even if it is less than 15 meters, but the area of the exterior wall doors, windows and decorations is greater than 6 percent of the surface area of the exterior wall, it is calculated according to the double-row scaffolding, and when the building height is greater than 30 meters, it is calculated according to the actual situation and the double-row scaffolding of the section steel platform. 3. The independent column is calculated according to the perimeter of the structure periphery plus the meter multiplied by the height of the design column, that is, it is substituted into the single-row outer scaffolding, and the concrete beams and walls poured on site are calculated according to the height of the Kunping or the upper layer of the board to the middle of the ladder plate in the Zhao room multiplied by the length of the measured wall, that is, it is substituted into the double-row outer corner scaffolding. Hope it helps!

Hello, the above questions will be answered by me. The outer scaffolding is erected according to the perimeter of the outer frame of the building x the erection height. Calculation formula:

Should the hollow part of the construction area of the exterior wall scaffolding be deducted?

Hello, the above questions will be answered by me. The outer scaffolding and the inner lifting scaffold are calculated in square meters (m2) according to the vertical projection area of the wall, and the opening and empty area of doors and windows are not deducted. Hope it helps!

I want floor floor area.

Hello, the above questions will be answered by me. First of all, it is certain that the comprehensive scaffolding of the exterior wall is not calculated in this way, because there is a provision in the quota that "doors, windows and openings are not deducted". In the actual project, this hollow part may need to be tiled or the like, and scaffolding is erected.

It can be regarded as a full house, but whether Party A gives it or not, it has to be pulled. Hope it helps!

The area of the outer scaffold is calculated according to the calculation rules, according to the product of the perimeter of the outer frame of the building * the erection height;

The calculation formula is: outer scaffolding area = [(total length of the building + erection width * 2) + (total width of the building + erection width * 2)] * 2 * erection height + erection length with protrusion or indentation in other parts * erection height.

The scaffolding steel pipe is made of 48mm with wall thickness; The maximum length of the transverse horizontal rod is 2200mm, the maximum length of other rods is 6500mm, and the maximum mass of each steel pipe should not be greater than 25kg.

Fastener-type steel pipe scaffolding is made of fasteners made of malleable cast iron, and its material should comply with the current national standard "Steel Pipe Scaffolding Fasteners" (GB15831); Fasteners made of other materials should be tested to prove that their quality meets the provisions of the standard before they can be used.

The fasteners used in scaffolding shall not be damaged when the bolts are tightened to a torque. Liquid Zhaomin.
