An agricultural working machine frame structure for such a working machine as well as methods of manufacturing such a frame structure

The invention relates to a frame structure (10) of an agricultural working machine. includes the frame structure (10) - at least two intersecting profiles (12, 14), - at least one pipe connection socket (16), via which the at least two intersecting profiles (12, 14) interlocking with one another and / or are integrally connected, and wherein the at least one pipe connection socket (16) has a first portion (which is one of the profiles 14) at least partially engages around or in which one of the profiles (14) protrudes, and wherein the at least one pipe connection socket (16) has a second portion which at least partially surrounds or one of the profiles (12) in which one of the profiles (12) protrudes , The frame structure (10) is characterized in that the at least one pipe connection socket (16) has a third portion bridges which a defined distance between the at least two intersecting profiles (12, 14), wherein the at least one pipe connection socket (16) in this section has a cross section which is designed such that a largely homogeneous voltage waveform at the junction of at least two intersecting profiles (12, 14) is achieved. The invention also relates to a method for manufacturing such a frame structure (10).
