Abstract
Abstract This specification discloses a building structure including a structural member comprising a web, two flanges projecting from opposite edges of the web and inturned lips at the free edges of the flanges; electrical wiring laid in a channel defined by one of the flanges, its inturned lip and the portion of the web adjacent to said flange; and a U-section cover member having limbs which interfit with said lip and said portion of the web and a base which extends over the mouth of the channel thus protecting the wiring.

A building structure including a structural member comprising a web, two flanges projecting from opposite edges of the web and inturned lips at the free edges of the flanges; electrical wiring laid in a channel defined by one of the flanges, its inturned lip and the portion of the web adjacent to said flange; and a Usection cover member having limbs which interfit with said lip and said portion of the web and a base which extends over the mouth of the channel thus protecting the wiring.
Claim 3
Dependent Claim
32 words
A building structure as claimed in claim 1 wherein the two flanges of the structural member project from the same face of the web so that the member is generally of U-section.
Claim 4
Dependent Claim
