Abstract

A steel framed building construction (50) includes external wall frames (52, 54) and internal wall frames (57, 58) which support one or more planar ceiling frames (56). A roof structure includes one or more substantially planar roof frames (76, 78) extending substantially parallel to associated roof surfaces which the roof frames support. The roof structure further includes support means (70, 74) extending between the roof frames (76, 78) and the ceiling frames (56) to transfer the weight of the roof structure to the ceiling frames (56) to thereby distribute the combined weight of the roof structure and the ceiling frames (56) and the support means (70, 74) through the external and internal wall frames (52, 54, 57, 58). A new roof structure is also claimed. A construction methodology whereby the wall frames, the roof frames and the roof support frames are all constructed from the same steel section is also claimed. A structural frame constructed from a number of intersecting structural members of a U-section with inward strengthening folds (14) is also claimed. The folds are formed back to the plane of the associated arm (12) at each junction between intersecting structural members (10). A method of slab preparation wherein the ceiling frame (56) is used as a template is also claimed. A method of constructing a roof structure includes moving preassembled planar roof frames into position lying substantially planar to the plane of an associated intended roof surface to thereby support the associated roof surface in the finished roof. The roof frames (76, 78) are supported in their respective inclined positions.
