Abstract: A green or sustainable building infrastructure comprising conjoining modular building segments. The purpose of the invention is to increase the precision, quality, and timing of building projects by allowing modular building segments to be constructed in an off-site controlled environment, transported, and quickly assembled on site. The conjoining modular building segments are prismatic box-like structures conjoined in a variety of configurations, each having at least three walls. The prismatic box-like structures are arranged and attached horizontally to create ceilings and floors, and they are arranged and attached vertically to create walls for the infrastructure. Some of the walls may be removed and the space inside each prismatic box-like structure is available for storage. The prismatic box-like structures may have certain dimensions, comprise specific materials, or be constructed or conjoined in specific ways.

Abstract: A roller assembly includes a frame (16) defining a doorway (14). A rail (32), which includes at least one supporting surface along at least one side of the rail, is secured to the frame (16). At least one roller (38), which is adapted to roll along the supporting surface of the rail (32), has a tire material (68) that contacts the rail (32). A thermal barrier (62, 70, 72, 76, 80) is positioned to inhibit heat transfer from the rail (32) to the tire material (68).

Abstract: A hanger for attaching a load-bearing object to a rib includes a gripper having a gripper body, the gripper body having a plurality of tabs depending therefrom; a cradle having a cradle body, the cradle body defining a gripper body receiving recess for receiving the gripper body, the gripper body received within the gripper body receiving recess; a fastener passing through the cradle body and the gripper body; and a stop threadably secured to the fastener, wherein the cradle is positioned between the gripper and the stop, the fastener coacting with the gripper and the cradle, whereby movement of the stop in a first direction causes the cradle body to coact with the gripper body causing the plurality of tabs to move toward each other. A kit for assembling the hanger and a hanger system utilizing the hanger are also disclosed.
