Abstract: The module for machine construction, comprises two sheet metal plates standing vertically to each other and firmly connected together in a connection line by a row of welding joints, a row of plug-in slits (10) in a division (T) notched in the area of the connection line of one of the sheet metal plate (BP1), and plug-in tongues (20) formed at an outside of the other sheet metal plate (BP2) in same divisions and coordinated in its width on the length of the plug-in slits. The row of plug-in slits limits directional transverse slit (19) vertically to the connection line of the plates. The module for machine construction, comprises two sheet metal plates standing vertically to each other and firmly connected together in a connection line by a row of welding joints, a row of plug-in slits (10) in a division (T) notched in the area of the connection line of one of the sheet metal plate (BP1), and plug-in tongues (20) formed at an outside of the other sheet metal plate (BP2) in same divisions and coordinated in its width on the length of the plug-in slits. The row of plug-in slits limits directional transverse slit (19) vertically to the connection line of the plates and is divided into small area around the plug-in slits. The width of the plug-in slit and the depth of the plug-in tongues are adapted at the strength of the plates. The plug-in tongues are firmly connected with the plug-in slits by welds. The welds direct in the area vertical in the connection line. The adjoining sides and side section of the plug-in slits and plug-in tongues are provided with one another. The edge areas of the plug-in slits are locked out by concave curvature. The plug-in tongues pass over concave transitions (27) in the outside (26) of the other plate (BP2) and have convex arched transitions in the area of the plug-in slit passing parallel to the outside. The transverse slit overreaches around the width of the plug-in slit. The depth of the plug-in tongues and the width of the plug-in slit of the same strength correspond to the plates. The both plates form a profile section with L-forming cross-section. Three plates are connected together by two rows of connections out of plug-in slits and plug-in tongues to a profile section with U-forming cross section. Four plates are connected together by four rows of connections out of plug-in slits and plug-in tongues to a square hollow profile section. An open forehead side of the hollow profile section is locked by a cover plate that is connected by four rows of connections with four plates of the hollow profile section. Both open sides of the hollow profile section are locked with the cover plate and form a closed housing with the hollow profile section. The plug-in slit of one of the plate passes in the area of the width of the other plate. The transverse slit protrudes over both longitudinal side of the plug-in slit and divides the band forming area around the plug-in slit. The plates are connected together in T-shape. Several plates are connected together to a machine frame and/or machine housing over inventive connection. The firm connection is produced between the plates by rivets.
