Puyang House Prefabricated Roof Reinforcement

The reinforcement of prefabricated roofs of houses in Puyang can be carried out through professional engineering implementation or by entrusting local reinforcement companies. The specific plan needs to be selected according to the structural inspection results.

I. Reference Engineering Case: Reinforcement of Class C Dilapidated Building Renovation by Puyang River Administration Bureau

In the renovation project of the west office building of the Puyang River Administration Bureau, systematic reinforcement measures were taken for the main structures such as prefabricated floor slabs and beams and columns:

1. Structural Reinforcement: Professional reinforcement is carried out on key load-bearing components such as prefabricated floor slabs and beams and columns. Methods such as carbon fiber cloth pasting, steel plate bonding reinforcement, or the addition of additional components through steel bar planting may be adopted to enhance the overall load-bearing capacity of the structure.
2. Surface Layer Repair: Simultaneously repair the building surface layer to address issues such as cracks and hollowing caused by structural deformation, restoring surface flatness and durability.
3. Energy-Saving Renovation: Add insulation layers or replace energy-saving doors and windows on the basis of reinforcement to improve building energy efficiency and extend service life. This case shows that the reinforcement of prefabricated roofs needs to take into account both structural safety and functional repair, and must be carried out by a professional team.

II. Service Capabilities of Local Reinforcement Companies in Puyang

There are several qualified building reinforcement companies in the Puyang area that can provide full-process services including "design - construction - technical services". Common reinforcement methods include:

1. Carbon Fiber Reinforcement: Suitable for the flexural reinforcement of prefabricated floor slabs. By pasting carbon fiber cloth, the stiffness and crack resistance of the components are improved. The construction period is short, and the self-weight increase is small.
2. Steel Plate Bonding Reinforcement: Steel plates are pasted at beam-column joints or the edges of floor slabs to enhance local load-bearing capacity. It is suitable for scenarios where the load has increased or the structural damage is relatively severe.
3. Steel Bar Planting Reinforcement: Additional components are added by drilling holes, injecting glue, and planting steel bars to solve the problem of weak connections between prefabricated components. It is commonly used at floor slab joints or areas with additional loads.
4. Comprehensive Services: Some companies provide one-stop services including structural inspection, reinforcement plan design, and construction supervision. They can customize plans for issues such as aging, cracks, and deformation of prefabricated roofs.

III. Implementation Suggestions

1. Preliminary Inspection: Entrust a professional institution to conduct a structural inspection of the prefabricated roof to clarify the degree of damage and reinforcement needs.
2. Method Selection: Select an appropriate reinforcement method according to the inspection results. For example, carbon fiber reinforcement can be used for minor cracks, and a combination of steel plate bonding or steel bar planting is required for severe deformation.
3. Company Selection: Give priority to local companies with special engineering contracting qualifications and rich case experience to ensure construction standardization and convenience of post-maintenance.
