Full Production Process of Prefabricated House Beams
The full production process of prefabricated house beams includes steps such as construction preparation, mold making, formwork assembly, steel bar operations, concrete construction, curing, inspection, form removal and roughening, lifting and transportation, and site cleanup.
Construction Preparation: Based on the design drawings, carry out pre-prefabrication preparations, fabricate the external structure, and process and bind the steel bars required for the prefabricated beams. Steel bar processing includes processes such as cutting, bending, and welding to ensure that the shape and dimensions of the steel bars meet the design requirements. When binding the steel bars, use auxiliary tools such as guide bar clamps to ensure accurate positioning and spacing of the steel bars.
Mold Making: Make molds according to the dimensions and shape of the beams. The molds can be made of steel or wood and should have sufficient strength and stiffness to ensure the accuracy of the shape during concrete pouring.
Formwork Assembly: Perform operations such as side formwork installation and edge formwork assembly. Before assembly, a release agent can be applied. After assembly, close the mold.
Steel Bar Operations: Carry out work such as rib plate steel bar installation, steel bar cage binding, and steel connector fabrication, while also embedding pre-embedded parts.
Concrete Construction: Pour the pre-prepared concrete into the beam molds and perform布料振捣 (布料振捣 can be translated as 'distribution and vibration compacting' in a more technical context, but for simplicity, we'll use 'pouring and vibration'). Use a gantry crane to lift the concrete hopper to above the prefabricated beam mold to be poured, open the discharge port, and pour while vibrating with a vibrating rod. After pouring is completed, use an iron trowel to smooth the concrete surface and pour concrete to the specified height in the top groove of the beam.
Curing: Embed a QR code tag into the concrete, ensuring the QR code faces upwards. Seal the steam curing shed tightly around the edges, insert the steam pipe into the shed, set the time and temperature, and start steam curing.
Inspection: Inspect the thickness of the protective layer, use a tape measure to check the extension length of the steel bars, measure the distance from the pre-embedded parts to the edge of the component, and observe the outer surface of the concrete to ensure there are no serious defects and that all inspected parts meet the acceptance requirements.
Form Removal and Roughening: After curing is completed, remove the mold and take the prefabricated beam out of the mold.
Lifting and Transportation: Connect a duckbill lifting device to the lifting pins on the beam, lift the beam component 200 to 300 millimeters, pause briefly to check if the component is secure, and then lift and transport the component after confirmation. Place wooden pads or steel supports at the bottom of the component, and then transport the beam to the site for installation or storage.
Site Cleanup: After the component production is completed, clean up the site, sweep away the garbage on the molds and the ground, and collect and store all the tools, drawings, and documents used.
