Cement Prefabricated House Reinforcement Plan

The reinforcement plan for cement prefabricated houses mainly includes three categories: structural reinforcement, joint and component reinforcement, and foundation reinforcement. It requires comprehensive design based on the current condition of the house, changes in loads, and functional requirements to ensure compliance with current building codes after reinforcement.

Structural Reinforcement:

1. Adding Reinforced Concrete Ring Beams and Structural Columns: By adding a closed frame system, the load-bearing performance of the original structure is improved, enhancing overall stability.
2. Using I-beams as Crossbeams: In prefabricated panel houses, I-beams are used as the main frame, with the placement density determined by the size of the profile (e.g., three 20-gauge steel beams placed in a cross shape with the panels). I-beam columns are erected for support, fixed to the walls, to enhance structural load-bearing capacity.
3. Adding a Layer of Concrete on Prefabricated Panels: Remove part of the prefabricated panels to create crossbeams, add vertical beams to form a cross shape, increase the thickness of the floor slab, and integrate the beams with the floor slab to improve safety.

Joint and Component Reinforcement:

1. Prefabricated Panel Joint Treatment: Use pressure grouting or carbon fiber cloth bonding to enhance the overall stiffness of the floor slab and reduce stress concentration at the joints.
2. Exterior Wall Reinforcement: Add a layer of steel wire mesh cement mortar to enhance the shear resistance of the walls and prevent crack propagation.

Foundation Reinforcement:

1. Grouting Reinforcement Method: Inject cement slurry or cement-water glass double slurry into weak soil layers using a high-pressure grouting pump to improve foundation bearing capacity and reduce uneven settlement.
2. Anchored Static Pressure Pile Reinforcement Method: Set up pile-driving holes indoors and use a hydraulic jack to press prefabricated reinforced concrete piles into the foundation, transferring loads to stable soil layers and controlling overall settlement.
3. Foundation Widening Reinforcement Method: Expand the base area of the original foundation to reduce foundation pressure and avoid settlement caused by overloading.
4. Compaction Method: Compact the original foundation soil layer using a pneumatic hammer or heavy-duty road roller to increase soil density to the bearing capacity standard.
5. Soil Replacement Method: Replace loose soil with high-density materials suitable for foundations (e.g., sand and gravel) to improve foundation performance.
6. Pile Driving Method: Embed reinforced concrete piles into soft soil layers to increase foundation stability, suitable for areas with poor geological conditions.

The reinforcement plan should be determined based on the actual condition of the house through professional testing and calculations to ensure that the reinforcement effect meets safety requirements.
