How to Prevent Earthquakes in Prefabricated Panel Houses

Earthquake prevention for prefabricated panel houses requires comprehensive measures in terms of house reinforcement, daily maintenance, and earthquake avoidance.

I. House Reinforcement

1. Foundation Reinforcement: Increase the foundation size, deepen the foundation, or add steel reinforcement mesh to enhance the foundation's load-bearing capacity; inject reinforcement agents or sealing materials to improve seismic performance.
2. Structural Reinforcement: Install steel beams, columns, or plates at key locations such as walls, stairs, and roofs to increase overall strength; inject reinforced concrete into the walls to improve their seismic resistance.
3. Frame Reinforcement: Add metal frames to the exterior walls of the house to enhance overall stability; fill the frames with reinforcement agents or sealing materials to further improve seismic resistance.
4. Seismic Isolation Reinforcement: Install spring isolators, rubber isolators, or other devices in the foundation or structure to reduce the direct impact of earthquake forces on the building and lower horizontal and vertical vibrations.
5. Steel Reinforcement: Add steel bars to walls, stairs, beams, and columns to enhance structural stability; for prefabricated floors, add a reinforced concrete layer no less than 40 millimeters thick on the surface or bottom to increase load-bearing capacity.
6. Other Methods: Use grouting reinforcement to fill cracks in walls or foundations; lay steel reinforcement mesh to reinforce walls or floors; attach steel plates for bonded steel reinforcement; add supports to reinforce walls or roofs.

II. Daily Maintenance

1. Regular Inspections: Inspect the house structure every six months to a year, focusing on issues such as cracks and deformations; if cracks in old prefabricated floors exceed 3 millimeters, immediately assess risks and reinforce.
2. Maintain Reinforced Areas: Regularly inspect reinforced steel beams, seismic isolation devices, etc., to ensure no rust, looseness, or damage; promptly repair脱落 (peeling) or aging of reinforcement materials.

III. Earthquake Avoidance

1. During an Earthquake: Immediately crouch down and hide under a sturdy table or piece of furniture when an earthquake occurs; use a pillow, backpack, etc., to protect your head and neck; stay away from windows, mirrors, large furniture, and other objects prone to collapse to avoid being injured.
2. After an Earthquake: Once the shaking stops, protect your head with both hands and quickly evacuate to an open area via the stairs; do not use elevators to avoid secondary injuries caused by aftershocks.

By implementing scientific reinforcement, regular maintenance, and correct avoidance measures, the seismic resistance of prefabricated panel houses can be significantly improved, ensuring the safety of life and property.
