Shijiazhuang Prefabricated Panel House Reinforcement
The reinforcement of prefabricated panel houses in Shijiazhuang requires a combination of professional inspection, scientific design, and standardized construction, with the operation carried out by qualified reinforcement companies.
Shijiazhuang has a large number of prefabricated panel brick-concrete houses built in the 1980s and 1990s. These houses have poor integrity and weak earthquake resistance, posing safety hazards. For example, the collapse of a prefabricated panel old building in the Railway 55 Dormitory in Xinhua District in 2026 exposed the limitations of old renovations that did not involve structural reinforcement. Therefore, reinforcement needs to be systematically promoted from the following aspects:
1. Structural safety inspection of the house is a prerequisite
Before reinforcement, a professional institution must be commissioned to conduct a comprehensive inspection, focusing on evaluating key indicators such as the connection nodes of prefabricated panels, wall bearing capacity, and foundation stability. The inspection should be carried out in accordance with standards such as the 'Reliability Appraisal Standard for Civil Buildings' to clarify the current safety level of the house and potential risk points, providing data support for subsequent design. For example, if cracks or voids are found at the connection between the prefabricated panel and the wall, a targeted reinforcement plan needs to be formulated.
2. Select a professional reinforcement company to formulate a scientific plan
There are several qualified reinforcement companies in Shijiazhuang. For example, Huayan Zhuozhu Urban Renewal Construction Group (Hebei) Co., Ltd. has patented technologies such as steel plate bonding reinforcement, carbon fiber reinforcement, and foundation treatment, and can provide customized plans according to the characteristics of prefabricated panel houses; Shijiazhuang Huazhong Building Reinforcement Engineering Co., Ltd. specializes in carbon fiber reinforcement, steel plate bonding reinforcement, and other projects, and can optimize construction techniques based on inspection results. Professional companies will select the most appropriate reinforcement methods according to the house's structural type, degree of damage, and usage requirements, such as using carbon fiber cloth bonding to strengthen prefabricated panel cracks and adding structural columns or ring beams to weak wall areas to improve overall integrity.
3. Construction materials and processes must be strictly standardized
Reinforcement materials must comply with national standards. For example, carbon fiber cloth must meet the requirements of first-grade products, and steel plate bonding adhesives must pass safety appraisals. Before construction, materials should be tested for compliance and a report should be issued. During construction, operations should be carried out in accordance with the 'Quality Acceptance Specification for Construction of Building Structure Reinforcement Projects'. For example, when performing steel plate bonding reinforcement, the flatness of the steel plate and the thickness of the adhesive layer should be controlled, and when performing carbon fiber reinforcement, the fiber direction should be consistent with the force direction. After construction is completed, an acceptance inspection should be carried out to ensure that the reinforcement effect meets the design requirements.
