Issues regarding the construction sequence of reinforced concrete frames~~
Thread Content
I’m sorry for the inconvenience; I’ve been in this field for only a short time and have not been to any construction sites. I have a small question: for a four-story reinforced concrete frame building with pile foundations, what is the sequence of construction? Once the foundation is in place, the reinforcement bars for the columns are installed, and then the area is cured for a few weeks. After that, is it necessary to pour concrete for the columns first, and only afterwards proceed with the beams and slabs of the second floor? Should we still bind the rebar for the columns below the second floor and the beams and slabs on the second floor together, set up the formwork, and then pour the concrete in one go?
If I remember correctly, that should be called a beam and slab on the first floor; architecture and structure differ by one floor. Beam, slab, and columns are poured together
Apply it together; usually one layer per week. If you want to speed things up, one layer can be applied in 4 days
Original poster, if you want to speed up the construction process, you must use an early-strength agent!
Original poster, when rushing to meet deadlines, be sure to pay attention to quality and safety.
Original poster, be aware that the formwork cannot be removed until the concrete has reached its designed strength.
Original poster, since the concrete has not reached its designed strength, not only can it not be demolished, but the supports for the formwork either cannot be removed.
Since the concrete has not reached its designed strength, it cannot be removed, nor can the supports for the formwork be taken away
Of course, depending on one’s own schedule requirements, it is also possible to pour the columns first and then the beams and slabs of the floor. However, regarding the frame structure, the poster didn’t mention the issue of floor beams – was there no design for them?
Generally, the columns are poured first, with the construction joint left at the bottom of the frame beams, and then the beam slabs are poured.
