You need to consider how many walls the constructional column contacts with. Add 30mm in each section and then times the height ( full height). If the constructional column is stubble type, you can measure the concrete quantity by filling method. For example, if the both sides of stubble is 60mm, you can calculate it as cuboid with 30mm at both sides, and calculate the template for 60mm at each side according to site operation. For example, if constructional column is 200 * 200, stubble is 60mm, and height of layer is 3.6 meters, then concrete quantity is 0.2 * 0.2 * 3.6 +0.03 * 0.2 * 3.6 + 0.03 * 0.2+ 3.6 = 0.1872 m3, and template amount (0.2+ 0.2) * 3.6 + 0.06 * 3.6 * 4 = 2.304 m2
The main difference is that you have to consider the concrete volume of stubble for constructional column, while for concrete column you don't have to. 1, calculation formula of concrete volume: Suppose sectional area of concrete column is S1, and height is H1, then the volume V1 = S1 × H1. 2, calculation formula of constructional column volume: Suppose sectional area of constructional column is S2, and height is H2, then the volume V2 = S2 H2 + N × (1/2 × D × K2 ×H2).
project quantity of external wall strip foundation =length of center line of external wall strip foundation × sectional area of ??strip foundation. project quantity of interior wall strip foundation = length of clear line of interior wall strip foundation × sectional area of ??strip foundation. note: Calculation of clear line① calculate brick strip foundation according to interior wall clear line. Calculation of constructional column project quantity ① constructional column volume = constructional column volume + stubble template. area of stubble template = length of stubble into wall (0.03) * height of constructional column ⑵, difficulties in calculation of constructional column project quantity ①, It is difficult to calculate the stubble of constructional column and you must consider how many walls the pillars cross with. ②, It is also difficult to calculate the template volume.
