How to Reinforce Prefabricated Panel Houses

There are various methods for reinforcing prefabricated panel houses, and appropriate solutions can be selected based on the actual situation of the house. Here are some common reinforcement methods:

Foundation Reinforcement

Increase the load-bearing capacity of the foundation by enlarging its size, deepening its depth, or adding steel reinforcement mesh. Additionally, reinforcement agents or foundation sealing materials can be added to enhance the foundation's earthquake resistance and ensure its stability under external forces such as earthquakes.

Structural Reinforcement

• Adding Steel Components: Install steel beams, columns, and plates at key locations such as walls, stairs, and roofs to enhance the overall strength and rigidity of the house.
• Injecting Reinforced Concrete into Walls: Inject reinforced concrete into the interior of walls to improve their earthquake resistance.
• Treatment of Panel Joints and Structural Columns: After detecting the location of panel joints through structural inspection, remove the original filling material, implant No. 6 threaded steel bars, and pour C30 fine aggregate concrete. Add structural columns at the four corners of the house, with a typical cross-section of 240*240 millimeters, reinforced with No. 6 and No. 8 steel bars, and connected to the floor slab.
• Erecting Temporary Support Systems: During the construction preparation phase, set up steel pipe supports every 1.2 meters along the length of the prefabricated panels, and use H-shaped steel beams to replace the steel beams at key nodes, with a steel beam cross-section of at least 200*200 millimeters.

Frame Reinforcement

Install metal frames on the exterior walls of the house to enhance its overall strength and stability. Add reinforcement agents or sealing materials to the frame structure to improve its earthquake resistance.

Seismic Isolation Reinforcement

Incorporate seismic isolation devices, such as spring isolators or rubber isolators, into the foundation or structure of the prefabricated panel house to reduce the impact of earthquakes on the building, effectively lowering the horizontal and vertical seismic forces generated by earthquakes and reducing house vibrations.

Other Reinforcement Methods

• Steel Bar Reinforcement: Add steel bars at key locations such as walls, stairs, and beams to improve the overall strength and stability of the house.
• Increasing Floor Slab Cross-Section Reinforcement: Add a reinforced concrete adhesive layer with a thickness of no less than 40 millimeters to the surface and bottom of the prefabricated floor slab to enhance its load-bearing capacity.
• Reinforcing with Carbon Fiber Sheets: Adhere carbon fiber sheets to the tensioned parts of the prefabricated floor slab in its direction, and set anchor points at the top to improve its load-bearing capacity.
• Reinforcing with Steel Plates: Adhere steel plates to the flexural members of the floor slab to increase its load-bearing capacity. However, it should be noted that before reaching the ultimate state, the steel plate should not be directly poured with concrete to avoid peeling or detachment issues.
• Grouting Reinforcement Method: Inject grout into walls or foundations to increase their overall strength and stability, improve earthquake resistance, and prevent deformation or cracks.
• Adding Support Reinforcement Method: Increase supports to reinforce walls or roofs, improving their load-bearing capacity and stability and preventing deformation or cracks.
