Disclosed are complex construction-supporting structures made up of two-walled, plane load-bearing structural modules which are designed for the production of two-walled, plane load-bearing structures that are made up of individual, assembled, plane load-bearing structural modules and form primary-shell load-bearing systems which in turn are combined, possibly with the additional use of complementary components such as plane truss elements (9), in order to form complex construction-supporting structures which can be used in the presence of rising sea levels or groundwater tables, poor foundation soils, and earthquakes.

A deck system is disclosed having a mounting plate with a planar support surface and at least one locating rod extending from the support surface. The locating rod extends in a direction that is substantially perpendicular to the support surface. A beam having a first end and a second end is positioned on the support surface of the mounting plate. The first and second ends of the beam have a slot and the slot is disposed for receiving the locating rod. At least one tread is disposed to extend between the two spaced apart parallel oriented beams. The tread has opposed shoulders on the side of the tread that engages the spaced apart beams. The opposed shoulders are disposed for engaging a side of the spaced apart beams that are in adjacent relationship.

Modular building methods and systems using precision machined modular panels. Standard modular panels are used for constructing walls, floor, and roof, with transitions from wall to roof and wall to floor provided by special transition panels. The standard panels include a channel formed configured to receive a flange of a C-channel member. The present method progresses by installation of a foam panel (or stack or row of such panels), followed by installation of a C-channel member, with the flange of such member engaged in the panels, followed by installation of an adjacent row or stack of panels, before installation of the next, adjacent C-channel member. Such alternating placement of panels and frame members eliminates the need for a tape measure, the need for any independent frame for the building, and ensures the walls, floor, and roof are square and plumb, as the precision machined panels ensure these requirements are met.

A double-shelled load-bearing structure module of any geometric shape, is formed from top and bottom secondary shell elements. A double-shelled load-bearing structure in the form of a primary shell structure is joined with the module, made of individual assembled load-bearing structure modules of this kind having statically necessary filling rods. The secondary shell elements have, in each corner, a connection pocket, which is open at the top or bottom or is open at the top and bottom, of appropriate size for connecting a plurality of load-bearing structure modules. The connection pocket, at least on the outside, on the outer vertical surfaces of the secondary shell elements, is delimited by preferably metal profiles or metal sheet. Connection tabs can also be disposed in each corner instead of connection pockets. The connection tabs are formed from angular surfaces, preferably metal sheet, protruding towards the intermediate space between the secondary shell elements.

Various implementations include a corrugated concrete floor system that includes a plurality of elongated pre-cast concrete floor support units disposed in a horizontal arrangement relative to each other for each floor of a building. The concrete floor support units are disposed between floors of a multi-story building. The units define a plurality of supply air plenums and return air plenums that are arranged alternately in the sandwich space between each floor. The supply air plenums are in fluid communication with the building level above them, and the return air plenums are in fluid communication with the building level below them. By having the supply-air plenum and the return-air plenum share the volume occupied by concrete floor support units, the height of the sandwich space is reduced.
