Abstract: A helical or “spiral” conveyor belt system is retrofitted with further belt supports, added between existing belt supports, when needed for heavier loading, preferably without removing the belt from the spiral support structure. The additional support apparatus includes a series of snap-on plastic brackets, to be snapped over the cantilevered bars that extend horizontally inwardly at intervals to support the belt. These brackets form channels within which a set of metal rail members are held, the rail members being in sections securable together around the helical path. A U-shaped wear strip, preferably continuous, is placed down over the metal rails after assembly. This rail addition can be accomplished without removal of the belt, which can be lifted in place sufficiently to assemble the intermediate support components.

Abstract: A modular habitation structure such as would be used in constructing a multi-room, multi-story building is disclosed. The modular structures includes floor framing formed from sections of structural support members such as steel channel beams securely interconnected to define the outline of a desired room shape. Upright sheet metal wall panels are fixed at their respective lower ends to the support members and at their respective height dimensions to each other to define the side enclosures of the room. A ceiling member of the same construction as the wall members is rigidly fixed to the upper portions of each of the wall members. The wall members, floor framing and ceiling are constructed and arranged and interconnected with each other to form a unitary, integral construction having a vertical load bearing capacity of a predetermined value greater than the weight of one completely constructed room and lateral force bearing capacity above a predetermined value.
