Aligned-Fiber Solid-Wood Ceiling Structure for Load Support

The patent employs a composite wood structure consisting of multiple layers (cover layers, intermediate layers, and a core layer) made from different wood materials and configurations. This composite approach enables the wooden ceiling structure to achieve concrete-level load-bearing capacity while maintaining sustainability. The cover layers provide compressive strength, the intermediate layers provide tensile strength, and the core layer provides structural stability, creating a composite material system that resolves the contradiction between strength and sustainability.

The patent divides the ceiling structure into functionally distinct segments: cover layers for compressive load bearing, intermediate layers for tensile load bearing and connection, and a core layer for structural stability. This segmentation allows each layer to be optimized for its specific function, enabling the overall wooden structure to achieve concrete-level strength while maintaining sustainability through full wood construction.

The patent applies local quality by giving different layers specific properties optimized for their functions: the cover layers have high compressive strength, the intermediate layers have high tensile strength and connection capability, and the core layer has high stability. This localized optimization of material properties within each layer enables the structure to achieve high strength-to-thickness ratio, maintaining structural stiffness while enabling thinner, more economical construction.

The patent merges multiple functional requirements into an integrated multi-layer wood structure where cover layers, intermediate layers, and core layer work together as a unified system. The layers are combined through material-to-material connection without requiring additional metal fasteners or complex joining mechanisms, thus achieving high load-bearing capacity while controlling manufacturing complexity through direct wood-to-wood bonding.
