(54) | Improvements in structural members |
(57) A channel-section structural member 1 for use as the bottom plate of a galvanised
steel building frame comprises a central web 2 and two parallel flanges 8 and 10 extending
along opposite edges of the web 2 to form a channel. Two ribs 4 and 6 are provided
in the web 2 for supporting the ends of upright structural members within the channel
in such a manner as to allow a gap for drainage of moisture along the channel. Drainage
holes 12 are provided in the structural member 1 so as to enable moisture to drain
out of the channel at points intermediate the two ends of the structural member 1,
thereby minimising the risk of accumulated moisture resulting in corrosion of the
structural member over a period of time. |
