What a civil engineer should know
Thread Content
1 Data a civil engineer should know 1. The amount of concrete and steel used in ordinary residential buildings: 1. Multi-story masonry housing: Steel bar 30KG/m2, concrete 0.3-0.33m3/m2 2. Multi-layer frame steel bar 38-42KG/m2, concrete 0.33-0.35m3/m2 3. Small high-rise 11th-12th floor steel bar 50-52KG/m2, concrete 0.35m3/m2 4. The 17th and 18th floors of high-rise buildings have steel bars 54-60KG/m2 and concrete 0.36m3/m2 5. The 30th floor of high-rise buildings H=94 meters steel bars 65-75KG/m2 and concrete 0.42-0.47m3/m2 6. The 28th floor of high-rise serviced apartments H=90 meters steel bars 65-70KG/m2 Concrete 0.38-0.42m3/m2 7. The amount of concrete and steel used in villas is between multi-story masonry residences and high-rise 11-12 floors. The above data is designed according to the rules of the seismic 7-degree zone. 2. Construction budget of ordinary multi-story residential buildings. Economic indicators 1. The area of outdoor doors and windows (excluding unit doors and security doors) accounts for 0.20-0.24 of the building area. 2. The template area accounts for about 2.2 of the building area 3. The outdoor plastering area accounts for about 0.4 of the building area 4. The indoor plastering area accounts for 3.8 of the building area 3. Construction effect 1. A plasterer plasters 35 square meters a day 2. A bricklayer lays 1,000-1,800 red bricks a day 3. A bricklayer lays 800-1,000 hollow bricks a day 4. Ceramic tiles 15 square meters 5. The first pass is 300 square meters/day, the second pass is 180 square meters/day, and the third pass is calendered 90 square meters/day 4. Basic data 1. Concrete weight 2500KG/m3 2. The weight of steel bars per linear meter is 0.00617 * d * d 3. The weight of dry sand is 1500KG/m3, the weight of wet sand is 1700KG/m3 4. The weight of gravel is 2200KG/m3 5. One cubic meter of red bricks is about 525 pieces (wall thickness) 6. One cubic meter of hollow bricks is about 175 pieces 7. It takes 1.3 cubic meters of ordinary sand to sift one square meter of clean sand
Looking at simple data, it’s easy to make mistakes if you don’t pay attention at work, so it’s very useful.
It's great if you can just open your mouth to get these data at work, which shows a person's basic skills!
Very good stuff, quite bluffing. I really didn’t know some of them, but I’ve learned a lot, thank you!
I also want to memorize it and pretend to be a civil engineer, hahahaha, thanks for sharing.
A bricklayer can lay 1,000-1,800 red bricks a day. It should be the workload of a skilled worker, it’s hard enough!
Oh, the on-site personnel should know better.
study* Well, thank you to the original poster for sharing so selflessly, which provides a lot of convenience for future generations.
