Splice joint of crane main girder
The invention relates to a splice joint (5) of a main girder (1) of a crane, whereby the main girder (1) comprises at least two longitudinal main girder parts (la) to be connected to each other by their ends and each having a central web (2) which comprises at least one web plate (2a), a longitudinal upper flange (3) or top plate arranged to the top part of the central web (2) as well as a longitudinal lower flange (4) which is arranged to the bottom part of the central web (3) and which protrudes from the central web (2) to its both sides. The splice joint (5) comprises, on both outer sides of the central web (2), a plate-like tongue- and-groove joint (6) receiving its the shear forces, the tongue-and-groove joint (6) in each case comprising a tongue (7) fixed to the central web (2) of a main girder part (la) to be joined, and a groove (8) fixed to the central web (2) of a second main girder part (la) to be joined; and a lower flange joint (9) receiving the bending forces of the splice joint (5), whereby the tongue-and-groove joints (6) on opposite outer sides of the web (2) are arranged reversed in relation to each other, and whereby the location of the tongues and grooves (7, 8) on opposite sides of the web (2) is reverse in relation to each other.
