Abstract: A concrete intermodal building unit for a prefabricated building structure including corner castings attached to contiguous rebars defining each corner of the concrete building unit. The corner castings can be mounted to the concrete building unit using solder, attachment plates for reinforcement, or rebar housings that connect the structural frame of the concrete building unit to the corner casting. Optionally, the corner castings can be mounted to the structural frame using I-beams.

Abstract: An anchorage device for supporting flat cover members for openings in building structures. The device includes two substantially similar stepped-plate members that include each an anchorage section and a supporting section. One of the stepped-plate members may in fact be flat or substantially flat, depending on the termination of the building openings to be protected. The anchorage section includes an opening and a cooperating fastening assembly for readily and removably mounting the device to the building structure with minimal aesthetic detraction or structural alteration. These sections define a plane each and these planes are kept in a spaced apart and parallel relationship with respect to each other by a step wall member. The supporting sections then are kept separate for their respective plates and the separation is sufficient to cooperatively receive the flat cover members that are used to protect the openings.
