The invention relates to a lightweight concrete building structure using pre-stressed lightweight structural beams 46 with a lightweight floor panel (48) spanning between beams (46). In a particular arrangement, the parking system using building structure (10) may be about less than half the weight than traditional parking building structures. In accordance with one arrangement of the particular embodiment of the invention, the building structure comprises floor structures having one or more structural beams, and one of more lightweight panels for attachment to the structural beam, wherein the floor structure is defined by joining together the one or more lightweight structural beams and the one of more lightweight panels. This particular arrangement is particularly useful because it permits defining a floor structure capable of sustaining relative large loads (such as a multitude of vehicles) using lightweight floor panels.

A building floor structure and a process for constructing the building floor structure comprising two or more spaced-apart beams, each beam comprising an upwardly facing support surface on at least one side of the beam; and one or more frameworks positioned between and adjacent two of the two or more spaced-apart beams, each of the one or more frameworks having two side regions, each side region comprising a downwardly facing bearing surface adapted to be received on the upwardly facing support surface of the respective beam.

Constructive system comprising at least four modular elongated prefabricated floor elements, each floor element defining a longitudinal axis parallel to its long side and a transversal axis parallel to its short side, and being arranged coplanar in a 2×2 matrix configuration such that each floor element is adjacent to another element by one of its long sides and adjacent to another of the elements by one of its short sides, the ends of the short sides of the floor elements resting on linear supporting elements, the floor elements comprising in the vertical face of each of the long sides a longitudinal groove having the direction of the longitudinal axis such that a cavity is formed between each pair of adjacent floor elements, the cavities being filled with a grouting, the system including at least one duct extending continuously along the two cavities and a post-tensioned tendon within the duct.

A precast concrete floor panel having stems molded in a mold with stem mold cavities and a deck. The deck can be formed in the same mold that includes the stem mold cavities or the concrete for the deck can be poured and cured on-site after the stems have been removed from the mold. The mold can include mold segments made from an insulating material that can remain attached to the stems to insulate the finished floor panel.

A method of manufacturing building panels includes assembling a frame of a building panel. The frame defines at least one cavity and at least one injection aperture in fluid communication with the at least one cavity. The method also includes positioning the frame on one of a base and a shelf of a multi-panel consolidation device having a plurality of shelves, with the shelves being in an expanded configuration, and at least substantially enclosing the at least one cavity. The method also includes forcing the shelves of the multi-panel consolidation device into a collapsed configuration, and injecting an expandable polymer through the at least one injection aperture into the at least one cavity. The method further includes forcing the shelves into an expanded configuration after a predetermined period of time selected to permit the expandable polymer to form a foam bonded to the frame.

A connector for connecting a wood substrate to a concrete layer. The connector comprising a shank adapted to engagement with a bore in the wood substrate with a length of the shank aligned with a central axis of the bore, the shank having at least an external portion made of a cement-based composition. In the built-up system, the connectors can have transversal ductile collapse characteristics providing a structural ductility of at least 50% to the built-up system with the wood substrate and concrete layer maintaining an elastic behaviour upon the transversal ductile collapse of the plurality of connectors.
