Prefabricated Partition Wall for Housing

Prefabricated partition walls for housing are pre-made concrete panel partition components that are manufactured in a factory and then transported to the construction site for direct assembly, belonging to prefabricated building products. The following provides an introduction from the aspects of characteristics, types, and construction techniques:

Characteristics

• Weight and Strength: They weigh only 1/6 to 1/8 of traditional brick walls, but their compressive strength is 2 to 3 times that of ordinary concrete, reducing building loads while ensuring structural stability.
• Versatile Functions: They offer sound insulation, thermal insulation, fire resistance, and moisture resistance, meeting the partition needs of various scenarios.
• Construction Advantages: Installation is 3 to 5 times faster than traditional bricklaying, with GRC panels reducing construction time by 30%. Dry construction methods reduce construction waste by 80%, increase usable area by 13%, and save on foundation treatment costs. High craftsmanship requirements allow for custom-shaped panels, breaking through the limitations of traditional bricklaying.
• Material Savings: Compared to traditional methods, they save 2.3 man-days, 1.64 square meters of formwork, 37 meters of 40*40 square tubes, and 21 square meters of steel wire mesh, with only an additional 0.22 cubic meters of mortar consumed.

Common Types

• GRC Panels: Reinforced with glass fibers, they have a sturdier structure, are easy to construct, and offer excellent waterproof and sound insulation properties.
• Cement/Expanded Clay Material Panels: For example, the slag concrete partition panels produced by Jiangsu Gangde Building Materials Co., Ltd. have characteristics such as sound insulation, thermal insulation, high strength, and impact resistance, suitable for residential buildings, offices, workshops, hotels, conference rooms, shopping malls, and other places.

Construction Techniques
Taking the renovation project of a resort's wellness vacation house as an example, the process includes:

1. Tool Preparation: Inspect the construction environment, ground base, and materials and tools, and complete technical disclosures and ground beam construction (line snapping → reinforcement planting → formwork erection → grouting → full grouting → formwork removal → curing).
2. Prefabricated Panel Mold Making: Use galvanized square tubes to make the mold frame, and lay a film to prevent adhesion and facilitate demolding.
3. Prefabricated Panel Production: Place steel mesh to enhance strength, pour concrete and implant welded parts, and remove the mold after natural solidification.
4. Prefabricated Panel Installation: Accurately align the embedded parts with the ground beam, wall, and ceiling, and fix them by welding.
5. Stone Paving: Drill holes according to the plan to install hangers, grind the stone surface and joints, and use the wet-laying method for paving.

In addition, panel partitions (such as lightweight panels) are joined together with adhesives without the need for studs, with a thickness of 60 to 100 mm and a width of 600 to 1000 mm. After installation, the bottom needs to be sealed and the panel joints treated. The construction process includes cleaning the base, marking wall positions, panel matching, and installing fixing clips.
