(I) aluminum veneer of curtain wall

1. Aluminum veneer: according to the dimensions shown in the figure, the folded edges of aluminum veneer are not included in the range of 25. (Statistics of arc surface and formed aluminum plate)

2. Aluminum profile: calculate the length of various specifications of aluminum multiplied by the linear density, and calculate the weight in kilograms.

3. Steel: first calculate the specification length, and then convert it into the composition of kg.

4. Embedded parts and angle steel supports: calculate the number of blocks according to the specifications, and then calculate their composition.

5. Thermal insulation rock wool: calculated in cubic meters according to the design drawing.

6. Sealant: first calculate the length of different sealant joints according to the drawing, and then calculate it into several numbers (generally, 500ml sealant is packaged into 3M long 16mm sealant, 592ml sealant is packaged into 16mm wide sealant, and 3.5m sealant).

Or as follows:

Joint width (sister) * joint thickness (sister) (the thickness is calculated by 10 sisters or half of the width) * joint length (m) / volume of each glue (ML) = quantity of glue.

7. Other information: working days, including foam bar, paper, rubber pad, cutting pad, electrode, anti rust paint, etc

According to the calculation, the price is 5-10 yuan / m2 at the recovery price.

2、 Surface treatment

1. Fluorocarbon spraying: calculate the number of square meters according to the spraying area;

2. Powder spraying: calculate the number of square meters according to the spraying area;

3. Anti rust paint: calculated according to steel composition;

4. Hot dip galvanizing: calculated according to steel composition;

5. Fire retardant coating (paint): calculated according to the composition of steel or the area of building space;

6. Waterproof coating: Calculation and construction of opening area;
