FIELD: construction.
SUBSTANCE: aluminium dome roof for a reservoir includes a bearing meshy frame made of rectilinear beams joined in assemblies with the help of assembly pads, resting against a steel support ring of a reservoir, a flooring welded from aluminium sheets in the form of a spherical shell and freely arranged on the frame. Between the flooring and the bearing beams there is a gap, where there is a pad installed along lengths of bearing beams. A stop is installed in the centre of the assembly pad. The height of the pad and the support is determined with account of thermal effect of welding at bearing beams.
EFFECT: provides for gas impermeability at excessive pressure in a gas space of a reservoir, higher accuracy of manufacturing, reduced time of reservoir assembly and installation.
