Riveted Joint:
A riveted joint is a permanent joint which uses rivets to fasten two materials.
Types of riveted joints:
1. Lap Joint
A lap joint is that in which one plate overlaps the other and the two plates are then riveted together.
Number of shearing planes = 1
2. Butt joint
A butt joint is that in which the main plates are kept in alignment butting each other and a cover plate is placed either on one side or on both sides of the main plates. The cover plate is then riveted together with the main plates.
Number of shearing plane in single cover butt joint = 1
Number of shearing plane in double cover butt joint = 2
Concept of shearing strength:
Strength of joint per pitch length in shearing, Pd = Ps × N × n
Where, Ps = Strength of one rivet in single shear, n = Number of shearing planes, N = Number of rivets
Calculation:
Given, Ps = strength of rivet in single shear, Number of rivets (N) = 2 in double riveted joints and number of shearing planes (n) = 2 for double cover butt joint
∴ \({P_d} = {P_s} \times 2 \times 2 = 4{P_s}\)
