Abstract

El invento se refiere a una junta de empalme (5) de una viga maestra (1) de una grúa, en donde la viga maestra (1) comprende por lo menos dos partes longitudinales (1a) de la viga maestra que van a ser conectadas entre sí por sus extremos y cada una tiene un alma central (2) que comprende por lo menos una placa de alma (2a), un reborde longitudinal superior (3), o placa superior, dispuesto en la parte de arriba del alma central (2) además de un reborde longitudinal inferior (4) que está dispuesto en la parte de abajo del alma central (3) y que sobresale del alma central (2) en ambos lados de ésta. La junta de empalme (5) comprende, en los dos lados exteriores del alma central (2), una junta machihembrada (6) semejante a una placa que recibe las fuerzas de cizallamiento, comprendiendo la junta machihembrada (6) en cada caso una lengüeta (7) fijada al alma central (2) de una parte (1a) de la viga maestra que va a ser unida, y una ranura (8) fijada al alma central (2) de una segunda parte (1a) de la viga maestra que va a ser unida; y una junta (9) del reborde inferior que recibe las fuerzas de flexión de la junta de empalme (5), en donde las juntas machihembradas (6) en los lados exteriores opuestos del alma (2) están dispuestas invertidas una con respecto a la otra, y por lo cual la ubicación de las lengüetas y ranuras (7, 8) en lados opuestos del alma (2) está invertida una respecto de la otra.
