<p>A method of constructing a building structure of a kind having a plurality of building frame wall units, each comprising a rectangular skeletal metal frame composed of top and bottom horizontal frame members connected by vertical frame members, erected and assembled in interconnected endwise relationship upon a supporting base foundation to form a load-bearing external wall, and a roof supported by said external wall, said method comprising the steps of: fabricating a horizontal skeletal base sub-frame in situ at ground level by assembling a plurality of elongate metal sub-frame sections and utilising releasable fastening means accessible externally of the sub-frame to connect together adjacent sub-frame sections; positioning within the contour of the base sub-frame a plurality of separate individual base plate elements and fastening such base plate elements to said sub-frame sections also utilising releasable fastening means accessible externally of the sub-frame; fixing tie rods between at least some of the base plate elements so as to extend between different sides of the base sub-frame; making adjustments to the assembly as necessary to ensure that all the base plate elements are accurately located and set in precise predetermined relative positions; utilising the base sub-frame as a mould and casting therein a moulded floor slab of rigid hard-setting moulding material substantially up to the level of the tops of the base plate elements, whereby said base plate elements and tie rods are embedded and fixed into said floor slab, releasing, from the exterior of the base sub-frame, the fastening means fastening the base plate elements to the sub-frame sections and the fastening means connecting together adjacent subframe sections, followed by removing said sub-frame sections so that the base sub-frame is dismantled and the base plate elements embedded and fixed into the floor slab remain, still set in their precise predetermined relative positions, to provide the supporting base foundation of the building structure; erecting and fixing the building frame wall units on said supporting base foundation so as to be assembled in endwise interconnected relationship, each wall unit being erected with its bottom horizontal frame member spanning over and being supported by adjacent base plate elements which are utilised as locating and fixing points for each said wall unit, and thereby forming the external wall; and constructing the roof which is supported by said external wall.</p> |
