What is a riveted joint called when two plates are placed edge-to-edge with dual rows of cover-plate rivets ___________________?
Show answer Hide answer
Answer: D. double riveted double cover butt joint
Explanation
A butt joint places two plates edge-to-edge and secures them using dual external cover plates fastened by multiple rivet rows. Using two cover plates, one on top and one on bottom, creates a double cover configuration that balances load transfer. Multiple rows of rivets on each side of the plate joint classify the assembly as a double riveted structural connection. Butt joints are designed to connect plates lying in the same plane without overlapping them directly like lap joints do. Cover plates distribute tensile forces across multiple rivet shears, greatly enhancing the overall efficiency of the structural connection. Riveted pressure vessels and boiler shells historically utilized double cover butt joints to withstand high internal steam pressures.
Lap point is not standard terminology for describing edge-to-edge plate connections secured with external cover plates. Single riveted joints feature only one row of fasteners on each side, lacking the multiple rows specified here. Single cover butt joints utilize only one external strap plate rather than the dual cover plates specified in this configuration.
