Abstract:
A modular system for the construction of a lattice panel for a structure, comprising first and second elongate chord members and a plurality of web members for attachment to the chord members so as to hold them apart transversely, wherein each web member comprises three legs forming a triangle, a first leg being adapted to extend perpendicularly between the chord members, and second and third legs being joined to each other and to adjacent the ends of the first leg, and wherein there are provided the following means for interlocking each web member to the chord members and to like web members:first interlocking means adjacent one end of the first leg to interlock with corresponding second interlocking means provided at intervals along the first chord member; third interlocking means adjacent the other end of the first leg to interlock with corresponding fourth interlocking means provided at intervals along the second chord member; fifth interlocking means adjacent the join between the second and third legs; and sixth interlocking means intermediate the ends of the first leg; the arrangement being such that the fifth interlocking means of one web member is adapted to interlock with the sixth interlocking means of an adjacent like web member; wherein the first leg is provided at each end with a junction unit, one being attached to the second leg and having the first interlocking means for connection to a chord member, and one being attached to the third leg and having the third interlocking means for connection to a chord member.
