Prefabricated Integral Structure Diagram of House
No specific content directly describing the prefabricated integral structure diagram of a house has been found at present, but information on the assembled monolithic concrete structural system can be provided. The assembled monolithic concrete structure is formed by connecting prefabricated concrete components in a reliable manner and combining them with on-site post-poured concrete and cement-based grout. The common systems and their characteristics are as follows:
1. External Wall Panel System
The prefabricated components include exterior walls, composite floor slabs, balconies, stairs, and composite beams. The vertical load-bearing structure is cast in place, and the exterior wall panels do not participate in load-bearing. The prefabrication ratio is generally 10%-50%. The construction difficulty is relatively low, and the cost is relatively low. It is often used in conjunction with large steel formwork construction. It is suitable for high-rise and super high-rise affordable housing, commercial housing, and office buildings, especially for scenarios with high requirements for construction efficiency and limited budgets.
2. Prefabricated Frame System
The prefabricated components cover columns, composite beams, exterior walls, composite floor slabs, balconies, and stairs. It has a high degree of industrialization, and the prefabrication ratio can reach 80%. The internal space has good freedom, but the indoor beams and columns are exposed. The construction difficulty is relatively high, and the cost is relatively high. It is suitable for apartment, office, hotel, school, and industrial factory buildings below 50 meters (with a seismic fortification intensity of 7 degrees), especially for low-rise or multi-story buildings with high requirements for space flexibility.
3. Prefabricated Shear Wall System
The prefabricated components include shear walls, composite floor slabs, stairs, and interior partition walls. It has a high degree of industrialization, with complete room space and no exposed beams and columns. The construction difficulty is high, and the cost is relatively high. It can choose partial or full prefabrication, and the space flexibility is average. It is suitable for high-rise and super high-rise commercial housing and affordable housing, especially for residential projects with high requirements for indoor space integrity.
4. Prefabricated Frame-Shear Wall System
The prefabricated components include columns (column formwork), shear walls, composite floor slabs, balconies, stairs, and interior partition walls. It has a high degree of industrialization, high construction difficulty, and relatively high cost. The indoor columns are exposed, but the internal space has good freedom. It is suitable for high-rise and super high-rise commercial housing and affordable housing, especially for buildings with high requirements for structural seismic performance and the need to balance space flexibility.
5. Composite Shear Wall System
The prefabricated components include shear walls, composite floor slabs, balconies, stairs, and interior partition walls. It has a high degree of industrialization, fast construction speed, simple connections, light component weight, and relatively low precision requirements. It is suitable for high-rise and super high-rise commercial housing and affordable housing, especially for projects with urgent requirements for the construction period.
Basic Types of Prefabricated Components
These include prefabricated concrete columns (solid columns, rectangular column shells), beams (solid beams, composite beams), shear walls (solid shear walls, composite shear walls), floor slabs (composite slabs, solid slabs, hollow slabs, double-T slabs), stairs, balconies, air-conditioning panels, parapet walls, and enclosure structures (exterior enclosure walls, interior partition walls), etc.
