Abstract: A structural member for facilitating quick and economical construction of pre-cast building elements comprising entire or partial panels such as walls, floors, ceilings, and roofs by combining metal stud framing with thin concrete or similar material for light-weight, low-cost, structurally strong panels. An illustrative structural member for constructing such pre-cast building panels is a segmented member made of a rigid material, such as a metal, that is secured to a stud by pressing a member including tangs through a cavity, by the insertion of fasteners through apertures in structural member tabs, or by adhesion or coalescence. The member may include upper tabs and apertures permitting the flow of concrete for additional structural strength. Reinforcement bars can be also incorporated. To reduce heat transfer and promote environmentally responsible and resource-efficient building, a break may be left between the stud and the concrete, with the break possibly filled by an insulative material.

Abstract: A structural element for the construction of any type of buildings, comprising a first “C”-shaped element with equidistant cavities at least on one of its faces and a second element in the shape of a continuous strip with equidistant angular folds, whereby once both structural elements are assembled to each other, the angular folds of the metallic strip are projected through the cavities of the “C”-shaped structural element.

Abstract: A construction system uses an elongate horizontal structural beam having a vertically oriented pair of side legs integrally joined to a base plate. The base plate lays abutting a structural ground surface with the side legs extending upwardly. The structural beam further comprising a number of horizontally spaced apart, tabs extending outwardly from the side legs. A number of elongate vertical structural beams, act as wall bearing members and have, integrally joined to a further base plate, a further pair of side legs adapted for abutting, at a first end, the first structural beam. Further tabs extend outwardly from the further side legs. Each of the tabs is derived as a cut-out portion of the side legs such that a major surface area of the tabs is positioned vertically or horizontally depending upon how the beam is positioned. A vertical concrete wall abuts the first and the second side legs and is positioned for enclosing all of the tabs for attachment of the beams to the wall.
