| 摘要 |
A structure is proposed for metal constructions, in particular of the trestlework type, with at least an angle iron having equal legs, each one of which being extended at its free and with a first and a second extension length having a width substantially equal to half width of a leg, the first extension length being positioned at right angle relatively to the first extension length, the second extension length being positioned at right angle relatively to the first extension length, in such a direction as to depart from the other leg of the angle iron. The structure is moreover provided with jointing elements each constituted by a plate suitable to be fastened on to the angle iron at least in correspondence of the inner surface of one of its legs, and in correspondence of the inner surface of the second extension length of its second leg. |
