How to Make Prefabricated Partition Walls for Houses

There are mainly two methods for making prefabricated partition walls for houses: light steel keel gypsum board partition walls and prefabricated partition wall panel installation. The specific steps and key points are as follows:

Light Steel Keel Gypsum Board Partition Walls

1. Fixing the Light Steel Keels
   Cut the light steel keels according to the design dimensions and fix them to the corresponding positions on the floor, ceiling, and both side walls using expansion bolts. Reserve the size of the door frame and install matching keels in the gaps. Use professional tools to reinforce the joints to ensure the stability of the keel framework.

2. Adding Wooden Blocks for Enhanced Stability
   Add extra wooden blocks at the door frame position and fix them with screws to prevent structural loosening due to frequent door opening and closing in the later stage. The size of the wooden blocks should match that of the keels to ensure seamless integration with the overall framework.

3. Laying Gypsum Boards and Soundproofing Treatment
   Start laying the gypsum boards on the keel framework from the door edge and cut off the excess parts with a utility knife. Fill the grooves on the back with soundproofing cotton (such as glass wool or rock wool) to reduce noise transmission. Then, lay another layer of gypsum board on the surface to form a double-layer structure for enhanced soundproofing effect.

4. Edge Trimming and Anti-Cracking Treatment
   Wrap the sides of the door frame with aluminum alloy edge trimming strips and fix them with screws to protect the edges. Hang glass fiber mesh at the joints, fill the gaps with white cement, and then stick kraft paper to prevent cracking. Finally, apply putty powder to complete the surface treatment.

Prefabricated Partition Wall Panel Installation

1. Factory Prefabrication Stage
   Produce preformed partition wall panels in the factory according to design requirements. Common types include:

   • Lightweight Panels (such as ceramsite concrete panels): Suitable for partition walls in residential buildings, with low cost and stable performance.
   • Composite Sandwich Panels (such as gypsum board with rock wool): Two layers of panels sandwiching soundproofing and thermal insulation core materials, suitable for scenarios with high soundproofing requirements such as office buildings and hotels.
   • Modular Integrated Partition Walls: Pre-installed with door frames, doors and windows, and even socket switches, suitable for chain hotels or fully furnished apartments for quick installation.

2. On-Site Assembly Construction
   After transporting the prefabricated panels to the site, complete the partition wall by assembling, bonding, or bolting the panels. The construction process is similar to 'building blocks', requiring no extensive wet work (such as bricklaying or plastering), significantly shortening the construction period.

Construction Details and Precautions

• Preliminary Preparation: Accurately measure the space dimensions, plan the keel positions, and ensure that all materials (such as light steel keels, gypsum boards, and soundproofing cotton) are available.
• Anti-Cracking Optimization: Special attention should be paid to the area around the door frame. The three steps of hanging mesh, applying white cement, and sticking kraft paper are indispensable.
• Cost and Efficiency: Prefabricated partition walls can save labor and material costs, especially suitable for large-scale renovation projects; light steel keel gypsum board partition walls are more flexible and suitable for manual operations.

Choose the appropriate plan based on actual needs (such as soundproofing effect, budget, and construction period). Light steel keel gypsum board partition walls are suitable for small-scale or personalized renovations, while prefabricated partition wall panel installation is more suitable for standardized and efficient projects.
