Technique for strengthening a frame and components necessary for implementing this technique. The technique is based on the placing of an inverted trapezoidal main beam or a trapezoidal main beam of a second type in the corner of a roof truss I. The ends of the parts P1, P2, P3, etc. in single file are inserted by a few centimetres into the gable walls MP1-MP2. Plates PL1-PL2 are placed under the ends of the main beam and in contact with the gable walls MP1-MP2. Uprights H1-H2-H3, etc. support the slides C1-C2-C3, etc. of the parts P1, P2, P3 etc. by means of forks F1, F2, F3, etc. and have, at their bases, flat elements Pa1, Pa2, Pa3, etc. Small plates Pq1, Pq2 are fixed at the edge of the gable walls to the main beam. Lugs 01, 02, 03, 04, etc. make it possible to instal a means for connection between Pq1, Pa1, Pa2, Pa3, Pa4, ... Pq2. This technique relates to the roof frames of houses, of terraced dwellings and of industrial constructions. <IMAGE>
