FLUID STORAGE RESERVOIR Russian patent published in 2024 - IPC F17C3/02 F17C13/00 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely, to vertical reservoirs mounted above ground outdoors or indoors for storage of process fluids and drinking water. Structure includes a bearing external steel body made of low-carbon steel with a zinc coating, a reservoir insulation circuit from a heat-insulating layer of walls and a roof, which includes polymer foam panels mounted on a lath of roofing beams. Besides, the structure includes stiffness belts, an auxiliary membrane representing the inner surface of the reservoir, assemblies for filling the reservoir and taking the contents of the reservoir. According to the invention, the reservoir contains upper and lower stiffening belts, which are angles bent under the diameter of the reservoir, a membrane fixed to the upper edge of the reservoir outline by means of eyelets and bolted joints, and a roofing corner strip fixed in the upper part of the reservoir above the ends of the roof panels. At the same time the external housing of the reservoir consists of sheets of low-carbon steel with zinc coating, fastened by means of bolted joints, the bottom of the reservoir is a reinforced concrete base, on which the reservoir with a protective coating from polyester nonwoven material and a foam polymer layer is installed.

EFFECT: increasing the service life by reducing the likelihood of deformation of elements and their fastening units during shrinkage of the structure and loss of tightness due to the impact of constant and temporary loads.
