The construction process for prefabricated traditional-style buildings primarily involves detailed component design, factory-based fabrication, pre-assembly of prefabricated parts, on-site hoisting, joint connection, and surface finishing. First, detailed designs are developed based on the building's traditional form and specifications; the structure is segmented into modules-such as columns, beams, purlins, rafters, roofing, walls, doors, windows, and decorative elements-with their dimensions, connection methods, and installation sequences determined. Following the design phase, materials are cut, processed, and numbered at the fabrication site according to the blueprints, ensuring components meet assembly requirements before arriving at the construction site.
The fabrication of timber components is a critical step, involving material selection, layout marking, cutting, mortise-and-tenon machining, drilling, milling, carving, and sanding. For buildings utilizing traditional timber structures, mortise-and-tenon joints must be crafted according to the specific load-bearing characteristics of each component to ensure the proper interconnection of columns, beams, and tie beams. Modern machinery enhances fabrication precision, while traditional craftsmanship is employed for complex joints and decorative details, thereby balancing production efficiency with the building's traditional aesthetic.
Pre-assembly and on-site assembly are also vital processes. Once fabricated, components may undergo pre-assembly at the factory or workshop to verify dimensions and fit; they are then disassembled for transport to the construction site. On-site construction follows a predetermined installation sequence, with the main structure assembled through hoisting, positioning, alignment, and connection. Components are secured using methods such as mortise-and-tenon joints, bolts, or steel connectors to ensure the stability of the joints. After assembly, the building undergoes a final inspection regarding overall verticality, elevation, component positioning, and the integrity of connections.
Additionally, the process encompasses roofing, the installation of doors and windows, and the application of traditional decorative finishes. Roofing involves a combination of prefabricated base layers and on-site installation, followed by tile laying and edge finishing, while doors and windows are positioned and installed using pre-fabricated components. Finally, surface treatments-such as wood staining, oil finishing, polychrome painting, and decorative carving-are applied to align with the building's traditional style. The overall construction process emphasizes "off-site prefabrication, on-site assembly, structural connection, and unified finishing," thereby enhancing construction efficiency and component fabrication quality while preserving traditional architectural forms and craftsmanship characteristics.
