Anonymous users2024-01-24If you want to add a reinforced concrete floor slab, it is not advisable to plant reinforcement directly in the perimeter beam and then cast the floor slab.
Reasons: 1. The anchoring force of the planting reinforcement is unstable (related to the construction quality and the quality of the planting reinforcement glue).
2. The durability of the planting glue is short (generally not more than 30 years).
Suggestion: Adopt steel structure floor slabs.
The living room span is larger, and the thickness of the board should be selected 130 150mm. According to the proportion of the length and size of the plate, the reinforcement should be calculated according to the two-way stressed plate according to Article GB50010-2010 "Code for Design of Concrete Structures". >>>More

DOUBLE-LAYER TWO-WAY REBAR, FLOOR SLAB POURING 12CM, COMMERCIAL CEMENT C30, 2 LAYERS OF 12MM REBAR SPACING 15CM AT THE BOTTOM, 15CM SPACING BETWEEN 2 LAYERS OF 8MM ON THE SURFACE.

If it is a self-built house in the countryside, it can be directly discharged through holes, if it is a high-rise developer with a smoke exhaust channel, if it is a five- or six-story residential building built in the eighties and nineties, you can just open a hole in the kitchen wall to drain it.
