A framing system comprises a plurality of laterally spaced-apart studs 41 or uprights. The studs 41 are interconnected by a header 2 which extends generally horizonontally .Each stud 41 comprises an elongated generally C-shaped lipped channel having a web 3 and side flanges 4,5 which extend continuously the length of the element.The side flanges 4,5 have inturned lips 7,8 at the upper edge to define agenerally C-shaped form.Each of the flanges 4,5 has an elongate slot 6 therin.The slot 6 is located on the central longitudinal axis of the flanges 4,5.The web 3 has a pair of laterally spaced-apart elongate slots 40 therein for mounting of an ancilliary element such as an angle cleat 50. The header 2 is of channel section comprising a web 10 and a pair of flanges 11,12 which extend to embrace the web 3 and flanges 4, 5 of the studs 41. The header 2 is sized such that the depending flanges 11,12 embrace the studs 41 to which it is to be secured in a relatively tight fit.The header 2 is mounted to the studs 41 in such a way as to accommodate limited vertical movement of the header 2 relative to the studs 41.Fixings 42,43 are screwed through the flanges 11,12 of the header and extend to engage in the slots 6 in the stud flanges 4,5. <Figure 14> |
