FIELD: construction, particularly to connect suspended ceiling beams.
SUBSTANCE: butt-joint assembly has end tab with front bent part creating guiding angle member and receiving pocket with widening outwards inlet. End part edge has profile providing end part self-aligning in vertical direction so that the end part is in line with receiving pocket of opposite butt-joint assembly. The receiving pocket has springing resilient wall, which limits assemblage force to be applied to restrict resistance of projecting spear-shaped locking members. Springing pocket wall, spear-shaped locking member shape and stiffening rims generate audio signal, namely click, which indicates connection operation termination. Spear-shaped locking member operates together with shaped groove to provide butt-joint assemblies self-alignment with each other.
EFFECT: improved end butt-joint assembly.
