Reinforced concrete floor slab is a structural building part with established standard dimensional parameters. Serially manufactured at specialized enterprises. For production, special vibration equipment and proven technology of pouring a concrete mixture of a certain grade into molds are used.
Structural diagram and production technology
Manufactured according to the standards of the domestic GOST PC slab is a concrete structure with a metal frame. Has longitudinal (along the entire length) holes. Production technology:
- A frame made of reinforcing steel bar is placed in a special container.
- Cylinders are installed to form voids in the future product.
- Concrete is poured.
- Vibration is applied.
- The workpiece is sent to the drying oven.
The standard continuous production procedure is carried out for 12 hours.
Control quality
All products undergo visual quality control before being sent to the warehouse - absence of defects, cracks, chips and damage. According to established standards, 5% of each batch (selectively) is sent to test benches. The following is checked:
- Compliance with dimensional parameters and dimensions.
- Resistance to lateral physical loads.
Studies are carried out to ensure the absence of hidden defects. X-rays and equipment emitting magnetic waves are used. A laboratory analysis of the composition and quality of the concrete mixture is carried out.
