<p>Two or more trusses, in hollow profile form, are joined together in the frame supporting a tent, or similar structure. Two form pieces, as connectors for two adjacent trusses, are partially inserted in their head ends, and fastened. In the parts protruding from the trusses they are form-locked together, with trusses at various angles. They can be extruded profiles, with interlocking internally and externally serrated sections. This system readily allows trusses to be set at different relative angles.</p> |
