Prefabricated PC House Design Drawings

Currently, prefabricated PC house design drawings cannot be provided directly, but the relevant design key points can be summarized as follows:

PC construction, also known as prefabricated concrete construction, involves producing building components in a factory and then transporting them to the construction site for assembly. Its design needs to integrate multiple factors, and the following introduces design-related terms and key points of the design process.

Design-related terms:

• PC structure: Also called prefabricated concrete structure, it is assembled from prefabricated concrete components through reliable connection methods and serves as the framework of prefabricated buildings. This structural form changes the traditional on-site pouring method of construction, improving construction efficiency and quality.
• PC components: These are prefabricated concrete components, which are concrete products processed and produced in factories through standardized and mechanized methods. They are the individual parts of prefabricated buildings. Common PC components include prefabricated wall panels, prefabricated floor slabs, and prefabricated stairs.
• Monolithic prefabrication rate: It refers to the ratio of the material consumption of the prefabricated components in the main structure and enclosure structure above ±0.000 of prefabricated buildings with concrete structures, steel structures, and other structural types to the total material consumption of the corresponding components. It reflects the degree of use of prefabricated components in the building.
• Monolithic assembly rate: It refers to the ratio of the quantity (or area) of prefabricated components and building products in prefabricated buildings to the total quantity (or area) of similar components or products. This indicator reflects the level of building assembly.

Key points of the design process:

• Familiarize with local policies: Before starting PC design, it is necessary to be familiar with the policy regulations regarding prefabricated buildings in the project location. For example, what is the specified prefabrication rate in the land transfer conditions and what are the incentive policies for prefabricated design in local policies. This helps in reasonable planning during the design process and making full use of policy advantages.
• Structural selection, cost estimation, and component selection: After determining the prefabrication rate of the PC building, select an appropriate PC structure according to the building height, building type, and requirements for the monolithic prefabrication rate. For example, high-rise commercial residential buildings are suitable for the assembled monolithic shear wall structural system. At the same time, select appropriate components based on the prefabrication rate and the cost of each prefabricated component. Generally, the cost of three-dimensional components is higher than that of planar components, and the cost of exterior walls with sandwich insulation is higher than that of exterior walls with integrated insulation, which is higher than that of ordinary exterior walls.
