Types of Rivetted Joint:

Riveted joints are broadly classified into two types:

Lap Joint

Where one member is placed overlapping over the other, and the connections are made by either a single or double row of rivets

(Figure (a)). In double row the rivets may be arranged in a chain-form or zig-zag form as shown in Figures (c) and (d).

Butt Joint

In that case, the members to be joined are placed end to end with each other and are covered together by means of cover plates, which carry the riveted connection.

The cover plate might be on one side (single cover butt joint), or on both sides (double cover butt joint) of the joining members as in Figure (b).

(d) Zig-Zag Rivetting
