The crosspieces consist of profiled elements which define a longitudinal race 25, into which ringbolts 29 are slideably assembled and locked to fasten a covering cloth 2. Beams 7 are assembled so as to converg in pyramidal form and to insert into a ridge central joint 8 placed at the top. Lastly there are corner joints 5 inserted at the top of the piers 3 to joint a beam 7 and a pair of adjacent lateral crosspieces 6 and means 36 associated with said central joint 8, to fasten and stretch the covering cloth 2. <IMAGE></p> |
