Roofing structure

Abstract

A roof beam is shown for a temporary building in which the beam comprises a first elongate member and a second elongate member, each comprising a box section with a hollow centre having a length, a width and a depth. The first elongate member is provided at each of two adjacent corners of its box section with a first connector extending lengthwise and comprising a channel closed off from the hollow centre of the first elongate member and open outwards through a neck narrower than the channel. The second elongate member has at each of two adjacent corners of its box section a second connector extending lengthwise and comprising a rib projecting through the neck of a complementary first connector and a flange on the rib held within the channel of the complementary first connector. In addition, the first elongate member and the second elongate member are respectively configured and arranged so that the first and second connector interconnect, with the second connector being a close fit within the first connector, whereby the first and second elongate members are coupled together to form the roof beam.
