The top floor of the new house is more than 5 meters high. Can I cast-in-place the interlayer? Does it affect the quality of the house?

Interlayer can be cast-in-place, but attention should be paid not to affect the structure of the house and avoid affecting the quality of the house.

Reinforced concrete cast-in-place

A, the construction requirements:

1, corners should be fixed with planting bars, and the main girder is not easy to be damaged.

2. The steel bar must adopt the national standard steel bar, and two or four layers are bound into a net with the spacing of 150-200mm.

3. Choose qualified cement products and river sand. (Cement 425 #

No.600, river sand, rock, the ratio is 1:2:3, stir evenly and vibrate with a special vibrator. adopt

Planting pole

)

4. Post-maintenance of the floor should be done well. (Not less than half a month is recommended)

5. When the span is too large, professional civil engineers should be asked to make calculations to avoid the danger caused by overweight.

6, reinforcement should be reasonable. As long as the design of concrete floor reinforcement is reasonable, it can play an early warning role even if there are major changes.

7. We divide the floor reinforcement into suitable reinforcement, less reinforcement and super reinforcement.

(1) Applicable reinforcement category: The designed reinforcement quantity is within a reasonable range. Once the floor is about to be destroyed, cracks will appear.

(2) Less reinforcement means less reinforcement, so the bearing capacity of the floor is poor;

(3) Super reinforcement refers to the reinforcement beyond the specification scope. (In this case, the floor can't reflect the damage in time when there is a problem, so the more reinforcement, the better.

)

Safety is the most important thing. We should choose a regular company specializing in the production of mezzanine. Of course, the cost of a regular company is definitely higher than that of those construction teams outside, but it is guaranteed. If a regular company has professional designers, engineers and construction teams, the quality can be guaranteed to some extent.
