In order to suspending a point load in a ceiling surface formed by a plate 1 in a building, a single round hole 2 is drilled in the plate, through which elongate, strip- shaped first legs 4A, 5A on two rigid angle-pieces 4, 5 are guided, the second legs 4B, 5B of which in closely joined state together form an eye-like fastening device having larger width than said first legs. A washer 10 having a hole rests against shoulders 8 formed on said second legs in a position tightly abutting the underside of the ceiling. The second legs of the angle-pieces are fixed in their positions relative to each other in their joined state by means of a bolt 12 having a nut, which at the same time connects the load with the fastening device. <IMAGE> |
