 The only way to form sheet metal parts is to connect. All kinds of parts are connected into an integral structure according to certain structural forms and corresponding positions. Usually, mechanical connection methods such as, bite, thread connection, expansion joint or welding and bonding are used. Welding belongs to non detachable connection, and other connections belong to detachable connection.



The following is the riveting connection method and selection of sheet metal structure:


Form of riveted joint: lap joint, butt joint, angle joint, plate type riveting, turn over riveting;


A. lapping method, characteristics and application: one plate or section steel is lapped on another steel plate for riveting, which can be used for load-bearing structure and adopted;


B. butt joint method, characteristics and application: place two steel plates or section steel joints on the same plane, and rivet the joints together with the cover plate as the connector. It can be used in load-bearing structure,

And adopt half round head solid rivet;


C. angle connection method, characteristics and application: connect two plates perpendicular to each other or at a certain angle, and use angle steel as the connection at the joint, there are two forms of single-sided and double-sided,


It can be used in load-bearing structure, and adopts half round head solid rivet;


D. plate type riveting method, characteristics and application: first, the end face of the plate is lapped with one end of the channel steel or the compression part, and then connected together by rivets;

E. riveting method, characteristics and application: lap one punched plate on another punched plate and turn over the hole edge, and then turn over the hole and press it tightly;

The rivets are riveted at the hole side, which are mostly used for sealing structure, and the flat round head semi hollow rivets are used;
