Illustration of Prefabricated Wooden Structure Houses

The illustration of prefabricated wooden structure houses mainly covers the composition of structures, construction processes, structural types, and connection details, as follows:

Composition of Structures

The core components of prefabricated wooden structure houses include foundation floors, structural floors, wall frames, and roof trusses. The foundation floor serves as the base, supporting the wall frames on the first floor; the structural floor is located between floors, transmitting loads; the attic walls and roof trusses together form the upper structure. All components are prefabricated in factories, ensuring dimensional accuracy through standardized processing. They are then transported to the site and quickly lifted and assembled using modern machinery (such as cranes) to form a complete residential structural framework.

Construction Process Illustration

1. Foundation Construction: First, complete a cast-in-place reinforced concrete slab foundation to ensure the bearing capacity of the ground; then pre-install the bottom floor treated with anti-corrosion for a stable platform for subsequent wall installation.
2. Wall Lifting: The prefabricated wooden structural wall panels from the factory are positioned one by one using cranes. Steel connectors (such as bolts and angle brackets) are used to achieve stable connections between components, avoiding on-site wet work and shortening the construction period.
3. Floor Assembly: The lifting of the second-floor load-bearing structure, attic floor, and roof is a critical step, requiring temporary supports for fixation. After verifying the overall stability, the supports are removed to form a rigid structural system.
4. Modular Assembly: The "building block" assembly method is widely used in North America. Wooden structural components are precisely processed in factories (such as mortising and drilling) and then transported to the site for rapid assembly through standardized interfaces, reducing human errors.

Structural Type Illustrations

1. Light Wood Frame Construction: Using dimension lumber (such as 2×4, 2×6) as the framework, it forms a shear wall system through nail connections. It is suitable for low-rise residential buildings, characterized by low cost and fast construction, and is widely distributed in ordinary residential houses in Europe and the United States.
2. Log Structure: Using whole logs (such as round logs and square logs) as the load-bearing material for walls, it forms thick walls through layering or staggered overlapping, offering excellent thermal insulation performance. It is commonly found in high-end villas in Russia and Europe and the United States.
3. Post-and-Beam Structure: Using large-section posts and beams as the load-bearing system, it transmits loads through mortise-and-tenon or metal connectors. It is suitable for large-span buildings (such as stables and commercial buildings) with flexible spatial layouts.

Connection Details

Steel connectors are the core of prefabricated wooden structures, achieving rigid connections between components through bolts and steel plates to ensure structural integrity; in Japanese wooden structures, traditional mortise-and-tenon connections (such as dovetail joints and straight joints) coexist with modern hardware connections (such as metal clamps in the "SE Construction Method"), balancing seismic performance and construction efficiency.

For specific illustrations, it is recommended to consult professional literature on wooden structure construction (such as the "Wood Structure Design Manual") or watch construction videos, which include construction step breakdown diagrams, node connection schematics, and structural type comparison diagrams.
