A prefabricated building component typically in the form of external wall cladding comprises in internal framework structure having multiple interconnected framework 5 members for forming a rigid base structure to which a building sheet is securely attached by a multitude of individual staples at spaced apart locations in which each staple is provided with two extended length legs for penetrating entirely through the sheet and partially through the framework structure. The building sheet is made from or contains cementitious material, preferably is autoclaved aerated concrete (AAC). io The prefabricated building component is manufactured in a factory using a staple gun fixedly connected to a movable bridge to selectively locate and insert staples into the component. The advantage is that the manufacture of the building component can be substantially automated, thus improving efficiency of manufacture and reducing costs. 7332688_1 (GHMatters) P98851.AU.1 <1 A16 |
