NOVELTY - The bracket has a base plate (1) mounted on a roof surface or at a ceiling using a liquid adhesive immediately after placement on the roof surface or the ceiling after placement of a finished assembly of a detachable component by a grid pattern (4). The base plate has diameter of about 200 to 350 mm at outer regions of a base plate bottom edge in an installation condition. The grid pattern is thinner than the floor thickness, which is defined by the base plate bottom edge, so that a space is available above and below the grid pattern to receive the adhesive.    USE - Vertically adjustable, motion accommodating and partially reversible universal mounting bracket for penetration-free assembly of detachable components e.g. photovoltaic plants, solar thermal energy plants, antenna or transmitters, ventilation system components, pipelines, advertising structures, and decoupling platforms, on a roof surface such as roof terrace, a ceiling or a bottom ceiling (all claimed) of a building. Uses include but are not limited to storage halls, football stadiums, optically delightful buildings, and parking deck.    ADVANTAGE - The universal mounting bracket is mounted on the roof surface using the liquid adhesive, so that the need for penetrating or formation of perforation in the roof surface is avoided, thus preventing failure points and leakage of rain water in the building. The design of the bracket allows avoiding the need of a heavy ballast feet or supporting structure, so that the bracket can be mounted on lightweight roof structures. The parts of the bracket are formed of elastomer plastic compositions according to the hardness and the elasticity of the parts such that damages of the roof surfaces caused by inelastic and rigid connection of the components on the roof are avoided. The components can be repaired and/or temporarily disassembled from the roof surfaces with less effort.    DETAILED DESCRIPTION - The liquid adhesive comprises hot liquid bitumen.
