Abstract: A fitting attachable to a cross-laminated panel provides a chase, plumbing space, airflow duct, or wiring route on an edge of the cross-laminated panel. The fitting may run between edges of multiple cross-laminated panels that contain integral hollow members, forming a customizable network of contiguous coplanar routing paths, accessible without installing pipes and wires behind, or in front of the cross-laminated panels. The fitting may also provide a vertical chase for single or multiple cross-laminated panels. The fitting takes advantage of one or more hollow members in the cross-laminated panels to provide contiguous routing paths for wires, pipes, and venting within the cross-laminated panels themselves, extending across any layout of multiple cross-laminated panels. The fitting may additionally serve as mechanical support for attachment of adjacent panels. Further, the fitting may provide structural connection for the CLT panels as required to meet structural code requirements for the building.

Abstract: A grid and skin assembly for use in a composite laminate structure is described. The assembly includes a metallic grid having a plurality of intersecting ribs oriented in at least two distinct rib directions offset at a grid angle relative to one another and defining respective intersection points; and a composite laminate skin having a plurality of ply layers comprising a plurality of tapes oriented in at least two distinct tape directions offset at a ply angle relative to one another. The grid angle is at least 25 degrees, the intersection points define glueless joints of the metallic grid, and the grid is a non-aluminum-based material. A grid and method of manufacturing the grid and skin assembly is also described. The method includes a water jet cutting procedure and glueless joint formation due to differing thermal expansion characteristics of the grid and skin.
