Cross-laminated timber panel structures, assemblies, and methods for making the same

A cross-laminated timber (CLT) panel structure assembly, comprising:

• (a) a first panel structure, including
• a first core layer, including
• a first plurality of hollow wooden bodies, each hollow wooden body of the first plurality of hollow wooden bodies defining a cavity that extends from a first open end of the hollow wooden body to a second open end of the hollow wooden body and being positioned adjacent to at least one other hollow wooden body of the first plurality of hollow wooden bodies,
• a first wooden surface layer connected to a first surface of the first core layer, and
• a second wooden surface layer connected to a second surface of the first core layer;
• (b) a second panel structure, the second panel structure including
• a second core layer, including
• a second plurality of hollow wooden bodies, each hollow wooden body of the second plurality of hollow wooden bodies defining a cavity that extends from a first open end of the hollow wooden body to a second open end of the hollow wooden body and being positioned adjacent to at least one other hollow wooden body of the second plurality of hollow wooden bodies,
• a third wooden surface layer connected to a first surface of the second core layer, and
• a fourth wooden surface layer connected to a second surface of the second core layer;
• wherein the second panel structure is connected to the first panel structure, such that the cavities defined by the first plurality of hollow wooden bodies are aligned with the cavities defined by the second plurality of hollow wooden bodies;
• and
• wherein each cavity defined by the first plurality of hollow wooden bodies and each cavity defined by the second plurality of hollow wooden bodies is configured to be at least partially filled with at least one of a mechanical, electrical, and plumbing (MEP) service, an insulative material for increasing the thermal resistance of the panel structure assembly, an acoustic material for reducing noise transmission through the panel structure assembly, and a ballistic material for enhancing the ballistic resistance of the panel structure assembly.

A method for constructing a cross-laminated timber (CLT) panel structure, the method comprising steps of:

• forming a plurality of hollow wooden bodies;
• adhering a first surface of the plurality of hollow wooden bodies to a surface of a first wooden surface layer, such that each hollow wooden body of the plurality of hollow wooden bodies is positioned adjacent to at least one other hollow wooden body of the plurality of hollow wooden bodies;
• and
• adhering a second surface of the plurality of hollow wooden bodies opposite of the first surface of the plurality of hollow wooden bodies to a surface of a second wooden surface layer.
