Abstract
A structural module has a cast concrete portion and a girder. The concrete portion has a reinforced deck with a reinforced load bearing a diaphragm at opposite ends. The girder extends between the diaphragms and protrudes into each diaphragm without structural connection thereto while being shear and tension coupled to the deck such that forces induced in the girder are transferred to the diaphragms via the coupling between the girder and the deck.
Claims16
A structural module comprising:
- a cast concrete portion;
- and
- a girder;
- the cast concrete portion comprising a reinforced deck having a reinforced load bearing diaphragm at opposite ends extending below the girder for placement on a support;
- the girder extending between the diaphragms and protruding into each diaphragm while being shear and tension coupled to the deck such that forces induced in the girder are transferred to the diaphragm via the coupling between the girder and the deck.

A method of making a structural module comprising the steps of:
- casting a concrete portion to define a reinforced deck having a reinforced load bearing diaphragm at opposite ends;
- placing a girder to extend between the diaphragms;
- shear and tension coupling the girder to the deck to transfer forces induced in the girder to the diaphragms via the coupling between the girder and the deck;
- wherein the concrete portion is cast such that the surface of the deck is the lower most surface of the casting and the diaphragms extend above the girder.
