Strengthening method of brick-concrete old house

The reinforcement method of brick-concrete old houses is an important step to ensure the structural safety of houses. The following are some common reinforcement methods:

1. Reinforced concrete reinforcement: Generally, reinforced concrete columns or wallboard are set on the external and internal walls of buildings, and the original structures or walls of buildings are connected with steel bars to improve the seismic capacity of building structures. This reinforcement method can increase the strength and crack resistance of reinforced concrete walls, and improve the bearing capacity and seismic capacity of buildings.

2. Steel structure reinforcement: replacing the wood structure, marble, gypsum, metal or other building materials of the old building with steel frame structure to provide stronger support and strength. When building steel structures are reinforced, conventional steel, steel plate, angle steel and profiles are generally used as materials to ensure the stability of their strength and supporting force.

3.FRP reinforcement: This method is to coat a layer of hard FRP on the surface of brick-concrete structure to improve the strength and seismic capacity of the structure. Glass fiber reinforced plastics not only have excellent chemical and physical properties, but also have the characteristics of light weight, acid and alkali resistance, heat resistance and corrosion resistance, and are ideal materials for strengthening building structures.

4. Traditional reinforcement method: wood, bricks, gypsum and other materials are used for reinforcement. However, the reinforcement effect of this method is usually poor, which requires more time and energy, and may also increase the weight of the house, leading to structural safety hazards.

In short, for the reinforcement of brick-concrete old houses, we should choose the appropriate reinforcement method according to the specific conditions of the houses. Before choosing the reinforcement scheme, architects need to carefully consider every detail to ensure the safety and stability of the building structure.
