Images of Prefabricated Components for House Additional Floors

Although we cannot directly provide images of prefabricated components for house additional floors, we can offer a detailed introduction to their types, characteristics, and common forms to help you form an intuitive understanding.

Prefabricated components for house additional floors are standardized parts used in building industrialization for quickly adding floors. They are typically prefabricated in factories and then transported to the site for assembly. Their core advantages include shortening construction periods, reducing on-site wet work, and ensuring construction quality. Common types include prefabricated beams, slabs, columns, stairs, and wall panels.

1. Prefabricated Beams and Slabs Prefabricated beams are mostly rectangular or T-shaped in cross-section, made of reinforced concrete or prestressed concrete, and used to support upper floors. Their spans can be adjusted according to design requirements, with common spans ranging from 3 to 6 meters. Prefabricated slabs are divided into solid and hollow types. Hollow slabs reduce their own weight through internal holes while maintaining load-bearing capacity, suitable for floor or roof additions in residential and office buildings. For example, prestressed hollow slabs typically have a thickness of 120-300 millimeters, meeting different load requirements.

2. Prefabricated Columns Prefabricated columns are mostly square or circular in cross-section, designed with high-strength concrete and high reinforcement ratios to transfer vertical loads. Their bottoms usually have reserved connecting reinforcement, fixed to foundations or lower columns through grout sleeves or welding to ensure structural integrity. In addition projects, prefabricated columns can be quickly positioned and installed, significantly shortening construction periods.

3. Prefabricated Stairs and Wall Panels Prefabricated stairs are integral or segmented structures, including steps, platform slabs, and support beams, with anti-slip surfaces and directly hoisted to designated positions. Prefabricated wall panels are divided into load-bearing and non-load-bearing types: load-bearing wall panels have built-in steel reinforcement skeletons to participate in structural loading; non-load-bearing wall panels (such as lightweight partition panels) primarily function for thermal insulation and sound insulation, with thicknesses typically ranging from 90-120 millimeters, made of autoclaved aerated concrete or composite materials.

4. Connection Node Design The reliability of prefabricated components depends on node connection technology. Common methods include:

• Wet connections: Achieving rigid connections between components by filling reserved holes with on-site poured concrete or grout;
• Dry connections: Using bolts, welding, or embedded parts for mechanical fixation, suitable for rapid assembly scenarios.
