Abstract
A foam core cement construction panel having shear members and lateral rails that form a channel-beam-like structure and novel methods of using the panels to form an integrated roof structure that serves three separate functions: (1) the roof load structure assembly; (2) the roof's exterior waterproof assembly; and (3) the roof's exposed interior ceiling assembly and which can include internal hydronics for added climate control.
Claims12
A generally rectangular construction panel comprising:
- a generally rectangular foam slab having a slab upper surface, a slab lower surface and slab lateral edges;
- a concrete panel bed covering said slab upper surface;
- a concrete panel floor covering said foam slab lower surface;
- construction panel concrete lateral edges extending from and integral with said concrete panel bed and said concrete panel floor;
- an upstanding concrete rail extending along and integral with each of the construction panel concrete lateral edges and extending above said panel bed so as to form a shallow U-shape with said panel bed wherein each said upstanding rail has a rail exterior sidewall and a rail top surface wherein said top surface is generally parallel to said panel bed;
- a plurality of spaced-apart shear key recesses formed at spaced apart locations in said rail exterior sidewall of each said rail wherein said key recesses are generally rectangular and extend from said rail top surface to above said panel bed whereby when two construction panels are placed side by side with their upstanding rails adjacent and their shear key recesses aligned, aligned shear key recesses form a shear pocket that is closed at its bottom and opened at the top surfaces of the side by side said upstanding concrete rails.
