Prefabricated House Beam Production

The production process of prefabricated house beams mainly includes key steps such as mold preparation and steel bar placement, concrete pouring and leveling, and forming and demolding, typically using standardized assembly-line operations to ensure quality.

Firstly, mold preparation and steel bar placement are the foundational steps in producing prefabricated house beams. Molds are generally made of steel, and some beam yards use mobile pedestals and hydraulic technology to enhance efficiency. Inside the mold, steel bars must be precisely placed according to design requirements, ensuring they are straight and evenly spaced to form a stable skeletal structure. The specifications, quantity, and arrangement of steel bars must strictly adhere to the design drawings, which is crucial for ensuring the load-bearing capacity of the beam.

Secondly, concrete pouring and leveling are the core processes. When pouring concrete into the mold, it is necessary to control the pouring speed and layer thickness to avoid segregation. After pouring, a vibrator should be used to thoroughly vibrate the concrete, expelling internal air bubbles and ensuring compactness. Subsequently, leveling is performed using a scraper or trowel machine to smooth the concrete surface and eliminate height differences, creating conditions for subsequent demolding and surface treatment.

Finally, forming and demolding are critical steps to inspect the production results. After concrete pouring, the beams must be left to cure in a well-controlled environment, typically using steam curing or natural curing methods to promote concrete strength growth by regulating temperature and humidity. Once the concrete reaches the design strength, demolding operations can proceed. Specialized tools should be used during demolding to avoid damaging the beam surface or edges, ensuring the quality of the finished product's appearance.

Additionally, the production of prefabricated beams typically adopts a standardized assembly-line operation mode, with each step from mold making and steel bar tying to concrete pouring and curing and demolding closely linked, forming an efficient production system. This mode not only improves production efficiency but also ensures that the dimensional accuracy, strength performance, and other indicators of the beams meet design requirements through strict process control, providing guarantees for the safety and durability of building structures.
