Prefabricated Concrete House Finished Product in Henan
The prefabricated concrete house finished product in Henan is a fully reinforced concrete structure, built using factory-prefabricated components and assembled on-site, offering high efficiency, cost-effectiveness, and durability.
Structure and Construction Method
The prefabricated concrete house takes a fully reinforced concrete structure as its main body. Through an industrial production model, the house is broken down into standardized components such as wall panels, floor slabs, and stairs. These components undergo steel bar binding, concrete pouring, and curing processes in the factory to ensure structural strength and quality stability. After being transported to the homestead, construction workers use a “building block” assembly process, fixing the components through bolted connections, welding, or cast-in-place joints to form an overall structure. This construction method significantly shortens the on-site construction period, allowing the main assembly of a villa to be completed in 4 hours and the entire building to be capped within two days.
Cost and Efficiency Advantages
The cost per square meter of a prefabricated house is approximately 300 yuan, lower than the construction cost of traditional brick-and-concrete houses. Its core advantage lies in industrial production reducing material waste and labor costs, while standardized components minimize on-site construction errors. Taking a 200-square-meter residence as an example, traditional construction methods require 3-6 months, whereas a prefabricated house only takes 2 days to complete the main structure, with the overall construction period shortened by more than 70%. Additionally, factory production is not affected by weather conditions, further ensuring construction efficiency.
Quality and Durability
The house has a design life of 70 years and meets national building structural safety standards. Reinforced concrete components are formed through vibration compaction processes in the factory, with concrete strength grades typically not lower than C30 and steel bar protective layer thickness strictly controlled within specified ranges, effectively resisting environmental factors such as carbonation and chloride ion erosion. Component joints are sealed with high-strength mortar or epoxy resin to ensure overall waterproof performance, adapting to the cold winters and rainy summers in Henan.
Scope of Application and Limitations
Currently, prefabricated house manufacturers in Kaifeng, Henan, can provide building plans up to 5 stories high, suitable for scenarios such as rural self-built houses, homestays, and small commercial buildings. However, it should be noted that prefabricated houses have certain requirements for the geological conditions of the homestead, necessitating foundation bearing capacity tests to ensure they meet design loads. Additionally, the pre-embedding of internal pipelines and decoration of the house still require on-site construction, necessitating coordinated design with the component production stage.
