摘要

1. Connection of at least two roof trusses (2) with several, essentially horizontally disposed purlins (1) having at both their ends downward extending supporting hooks (1.1) engaging suspension fish-plates (2.1) fixed by the roof trusses (2), secured by a locking device (1.3) against accidental lifting from the fish-plates (2.1), the purlin (1) being provided in its end sections with a bracket joint (1.4) extending transversally to the longitudinal extension of the purlin (1) and at a predetermined distance parallelly to the purlin bottom, provided with tiltable locking brackets (1.3), in particular for the construction of tent skeletons, characterized in that the locking bracket (1.3) is formed with its end directed away from the roof truss (2) heavier than the bracket end (1.3.1) showing towards the suspension fish-plate (2.1), and is bent in such manner that in the locked position the bracket end (1.3.1) extends about parallelly to the hook (1.1), being spaced therefrom by a distance approaching zero, the adjacent bent-off portion (1.3.2) of the locking bracket (1.3) resting against the inner edge of the suspension fish-plate (2.1), and that the angle between the bracket end (1.3.1) and the adjacent bent-off portion (1.3.2) amounts to 90 or more and the further bent-off portion (1.3.3) leading to the bracket joint (1.4) is ascending, while the heavier end (1.3.4) in relation to the purlin base is bent downward and the end section is formed as a stop for a purlin fork lift (3).
