FIELD: building units, particularly suspended ceilings.
SUBSTANCE: attachment units is made as profiled member including upper vertical ridge secured to wall, as well as upper and lower horizontal shoulders extending from upper vertical ridge. Parallel reinforcing ribs are created on horizontal shoulders. Extending from lower horizontal shoulder are two lower vertical ribs, namely proximate lower vertical rib arranged near wall and remote lower vertical rib spaced a distance from wall. Lower vertical ribs form opened cavity to insert harpoon with web secured to it.
EFFECT: possibility to use separate cuts of profiled member for suspended ceiling assembling, decreased contact stresses in ceiling web due to increased contact area, eliminated profiled member defects, namely rough edges and cavities, possibility of web load distribution on profiled member, increased bending and torsional rigidity due to forming ribs spaced in vertical direction, moving cavity for harpoon insertion from wall due to forming steps and undercuts, which facilitates web installation.
