Reinforcement of Brick-Structure Prefabricated Panel Houses

The reinforcement of brick-structure prefabricated panel houses can be carried out from aspects such as walls, floors, foundation bases, overall connections and structures, and other methods. The specific approaches are as follows:

Wall Reinforcement:

1. Reinforcement with Steel Mesh and Cement Mortar Surface Layer: Drill holes on one or both sides of the wall to insert anchor bars, bind steel mesh, and then spray or apply cement mortar to form a composite wall, enhancing load-bearing capacity and integrity.
2. Reinforcement with Reinforced Concrete Panel Walls: Pour reinforced concrete panels on one or both sides of the wall to strengthen lateral resistance and load-bearing capacity, although the construction is complex and space-consuming.
3. Addition of Buttresses or Brick Piers: Add brick or reinforced concrete buttresses inside or outside the wall to increase thickness and stability, suitable for areas with insufficient local load-bearing capacity.
4. Crack Repair and Seismic Reinforcement: Perform grouting or caulking for minor cracks; enhance seismic performance through methods such as brick removal and crack repair, steel bar anchoring, and wall attachment reinforcement.

Floor Reinforcement:

1. Addition of Reinforced Concrete Composite Layer: Pour a new concrete layer on the existing floor, ensuring the original floor can bear the additional weight.
2. Adhesion of Carbon Fiber Sheets or Steel Plates: Adhere high-strength materials in tension areas to enhance flexural load-bearing capacity, with simple construction and minimal space impact.
3. Addition of Supports: Add columns or supports to beams or floors with large spans to reduce bending moments and deflections.
4. Increase in Floor Section: Add reinforced concrete adhesive layers on the surface and bottom of prefabricated floors, with a thickness of no less than 40 millimeters.

Foundation Base Reinforcement:

1. Base Widening: Increase the base area by wrapping concrete or masonry to reduce foundation stress.
2. Base Deepening: Extend the foundation to more stable soil layers to improve issues with poor shallow soil quality.
3. Pile Foundation Reinforcement: Add reinforced concrete piles to transfer loads to deep, hard soil layers or rock formations.
4. Grouting Reinforcement: Drill holes and inject cement or chemical grout to fill soil pores, improving density and load-bearing capacity.

Overall Connection and Structural Reinforcement:

1. Strengthening of Wall-Floor and Roof Connections: Prevent structural detachment during earthquakes by implanting steel bars and adding tie bars.
2. Installation of Structural Columns and Ring Beams: Add reinforced concrete structural columns at house corners and intersections of vertical and horizontal walls, and install ring beams at floor and roof levels to enhance overall integrity and seismic capacity.

Other Reinforcement Methods:

1. Frame Reinforcement: Install metal frames on exterior walls to enhance overall strength and stability, with the option to add reinforcing agents or sealing materials to improve seismic performance.
2. Seismic Isolation Reinforcement: Install spring or rubber seismic isolators in the foundation or structure to reduce the impact of earthquake forces on the building.
