A pre-fabricated cement or concrete panel and an improved system for building construction using such panels is provided. The concrete panel has a threaded tubular connector (concrete insert) imbedded therein for receipt of a bolt. The tubular connector has a head portion, a spaced flange portion and a tubular bolt receiving body portion for receipt of the securing bolt. The flange is securely attached to the tubular bolt receiving body by any convenient method such as welding or crimping. Reinforcement bars are imbedded in the panels on each side adjacent to the periphery of the panel. The flange is placed at a predetermined position between the head and the open end of the bolt receiving body. The predetermined distance between the flange and the head is dependent on the diameter of the reinforcement bars. The distance is selected to allow receipt of reinforcing bars which are placed around the periphery of the cement panels so that the bars sit on the flange and nest against the bolt body in pressure engagement between the bolt head and the flange.

Composite building panels comprising a slab of cementitious fiber reinforced material and a stud framework keyed thereto. The studs have a flange which abuts the inner surface of the slab, and a plurality of tabs which project downwardly from the flange to key the stud. Adjacent tabs are axially spaced apart, and may also be transversely staggard, to reduce the incidence of cracking of the slab, and may be upset from the flange material. The slabs may be relatively thin i.e. 2 cms. The tabs may also serve to retain rod or mesh reinforcement in thicker slabs.

A concrete stud wall system includes elongated mounting strips having mounting brackets that are pressure inserted through longitudinally spaced slots in the outer flanges of the studs and tracks for attaching a reinforcing mesh and encapsulated by a poured concrete panel.

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. In the case that the concrete wall comprises a rebar network, individual bars are placed and spaced apart within the concrete wall so as to avoid interference with the tabs.

A framing system and related framing section assembly includes at least one first member, preferably in the form of a U-shaped track or channel, that receives at least one second member, such as a stud. The stud is captured on or between spaced protrusions or pairs of protrusions projecting inwardly from the opposed sidewalls of the receiver. The protrusions securely, but releasably, hold the corresponding end of the stud in place in the receiver. To form a framing section assembly using this system, two opposed receivers are provided for engaging and supporting each end of a plurality of studs. To permit variable positioning of the studs in the receivers and enhance flexibility during installation, the protrusions may be equidistantly spaced at frequent intervals. Surface indicia may also be provided on the receivers at certain conventional intervals to allow the installer to easily determine the proper location for the studs.
