METHOD OF FORMING CONNECTING ELEMENT AND CONNECTING ELEMENT Russian patent published in 2011 - IPC B23P11/00 F16D1/72 F16B4/00 

FIELD: process engineering.

SUBSTANCE: invention relates to connection of structural elements. Connection element and opposed contact surfaces are produced, element being made up of, at least, two structural elements to transfer compression force from first element to second element. Said contact surfaces overlap each other completely. Recesses with curved cross sections are made with due allowance for all edges of preset contact surfaces. Areas of thrust surfaces of both structural elements extending beyond said opposed both contact surfaces are separated in space therefrom.

EFFECT: decreased peaks of local stress originating in collapse load.
