The amount of concrete in general frame structure can be calculated according to “building area * 0.22”, that is, the converted thickness of a standard layer is about 550px; 2
.
The steel content of frame structure is calculated as 60kg per m2 temporarily (factors affecting the steel content of buildings are not considered); 3
.
Based on the above data, the steel content of each cubic meter of concrete = 1 / 0.22 * 60 = 273kg
.
12 walls need 64 standard bricks per square meter, 18 walls need 96 standard bricks per square meter, 24 walls need 128 standard bricks per square meter, 37 walls need 192 standard bricks per square meter, 49 walls need 256 standard bricks per square meter
.
Calculation formula: 240 brick consumption per cubic meter 1 / (0.24 * 0.12 * 0.6) 370 brick consumption per cubic meter 1 / (0.37 * 0.12 * 0.6) hollow 24 walls need more than 80 standard bricks per square meter Concrete consumption and steel consumption of residential buildings: 1

617 is the weight per meter of round 10 bars
.
The weight of reinforcement is proportional to the square of the diameter (radius)
.
G = 0.617 * D * D / 100 weight per meter (kg) = diameter of reinforcement (mm) × diameter of reinforcement (mm) × 0.00617 in fact, remember that the weight of reinforcement commonly used in construction engineering is very simple: φ 6 = 0.222kg, φ 6.5 = 0.26kg, φ 8 = 0.395kg, φ 10 = 0.617kg, φ 12 = 0.888kg, Φ 14 = 1.21kg, Φ 16 = 1.58kg, Φ 18 = 2.0kg, Φ 24 = 2.47kg, Φ 22 = 2.98kg, Φ 25 = 3.85kg, Φ 28 = 4.837kg …..
.
Take three digits after the general decimal point for the reinforcement below 12 (including 12) and 28 (including 28), take two digits after the general decimal point for the reinforcement from 14 to 25, take a simple formula for calculating the theoretical weight of steel material name theoretical weight W (kg / M) flat steel, steel plate and strip w = 0.00785 × width × thickness Square Steel w = 0.00785 × side length 2 round steel, wire rod and steel wire W = 0.00617 × diameter 2 steel pipe w = 0.02466 × wall thickness (outer diameter wall thickness) equilateral angle steel w = 0.00785 × side thickness (2 side width side thickness) unequal side angle steel w = 0.00785 × side thickness (long side width + short side width side thickness) I-beam w = 0.00785 × waist thickness [height + F (leg width waist thickness)] channel steel w = 0.00785 × waist thickness [height + e (leg width waist thickness)] remarks 1 The accurate calculation formula of steel, I-beam and channel steel is very complicated, and the simple table is used to calculate the approximate value

What’s the market of Erjian this year? Has it gone up again? How much is the cost of the first level fire engineer examination? Why is it difficult to pass the first level fire engineer examination? Why is the passing rate so low? After the announcement of the results of the second construction in 2018, you may face five choices for the second construction in 2019: of course, you should choose a major with high gold content

Finally, Shaoli education wishes all candidates to pass the exam at one time
.
Come and talk about the review plan in October
.
This month, we should love learning, indulge in learning and be good friends
.
We should start learning together, prepare for the exam, pass the enterprise promotion (maintenance) qualification service together, and learn more Experience training (from senior college to junior college, from junior college to undergraduate), training (constructor, fire engineer, economist), intermediate and senior engineer evaluation
.
For more information, please contact our admissions teacher, wechat customer service or Shaoli official website~ http://www.sh-shaoli.com At present, 10000 + people have paid attention to join us.
