Advantages of Non-Prefabricated Houses

Non-prefabricated houses (cast-in-place slab houses) have significant advantages in terms of flexibility, cost control, and adaptability, as detailed below:

1. Significantly Enhanced Construction Flexibility
Cast-in-place slabs can be customized according to the actual needs of the construction site. For example, when encountering irregular structures or complex spatial layouts, construction personnel can directly adjust the shape and size of the concrete pouring without relying on the fixed specifications of prefabricated components. This flexibility not only reduces material waste caused by mismatched components but also avoids additional costs incurred from design modifications. Additionally, the cast-in-place process allows for local optimizations during construction, such as adjusting floor slab thickness or adding embedded part positions, to better meet building functional requirements.

2. Outstanding Comprehensive Cost Advantages
Cast-in-place slabs achieve cost optimization by shortening construction periods and reducing material waste. On one hand, cast-in-place operations can be carried out simultaneously with other construction tasks (such as wall masonry and pipeline embedding), forming a流水作业 (assembly-line) mode that significantly improves construction efficiency. On the other hand, cast-in-place slabs eliminate the need for transportation and storage of prefabricated components, reducing logistics costs and site occupation fees. Meanwhile, the cast-in-place process can precisely control material usage, avoiding waste from off-cuts caused by dimensional deviations in prefabricated components, further reducing material costs.

3. Comprehensively Enhanced Environmental Adaptability
Cast-in-place slabs exhibit far superior adaptability to geological conditions, climatic environments, and building types compared to prefabricated slabs. In soft soil foundations or earthquake-prone areas, cast-in-place slabs can enhance overall structural integrity and seismic performance by adjusting reinforcement configurations and concrete strength grades. In high-temperature or extremely cold regions, the cast-in-place process ensures adequate concrete curing, preventing deformation or cracking caused by temperature differentials in prefabricated components. Additionally, cast-in-place slabs can seamlessly connect different building structures (such as frame structures and brick-concrete structures), resolving leakage issues at prefabricated component joints and improving building durability.

4. Superior Structural Performance
Cast-in-place slabs form a continuous structure through on-site integral pouring, creating stronger connections with beams, columns, and other components and effectively avoiding stress concentration issues at prefabricated component joints. This integrity not only enhances the load-bearing capacity of the floor slab but also better distributes loads, reducing the risk of local settlement. Meanwhile, the cast-in-place process allows for flexible arrangement of reinforcement meshes, enhancing the floor slab's crack resistance and extending the building's service life.
