FIELD: construction.
SUBSTANCE: invention relates to hollow tank support element and, in particular, it relates to hollow tank support element and hollow tank production method; invention relates to production of fuel tanks. Hollow tank support element comprises support part (2) and support end parts (1) located on two ends of support part. Support end parts (1) are equipped with stepped transition elements (4) for connection with support part (2). Support part (2) is made in the form of hollow structure. Support part (2) contains support main parts (5) and bases (6). Supporting main part (5) is made in the form of a cylindrical structure or in the form of a corrugated in the middle part of the cylinder.
EFFECT: technical result is the creation of a hollow tank support element and a method of producing a hollow tank, the structure of which can withstand deformations occurring under the action of high excess pressure or relatively low vacuum, and improve overall stability of article shape; at the same time this support structure is characterized by application of small amount of material with light weight.
