BUTT CONNECTION OF PNEUMATIC STRUCTURE ELEMENTS Russian patent published in 2022 - IPC E04H15/20 

FIELD: mobile prefabricated structures construction.

SUBSTANCE: invention relates to the field of construction of mobile prefabricated structures with full factory readiness at the manufacturing stage, in particular to temporary technological and domestic structures for the temporary accommodation of people, various industries and public institutions, namely to pneumatic building structures used in various sectors of the national economy. The butt connection of the elements of a pneumatic structure, containing a shell of a supporting structure made in the form of a set of separate air chambers, an air supply unit with air ducts, pneumatic units placed on the shell and connected to the air ducts, includes an inner rigid ring fixed on the inner side of the shell, and an outer rigid a ring fixed on the outer side of the shell, the inner rigid ring is made in the form of an inner flange with the possibility of installation on the inner side of the air chamber of the shell of the supporting structure, and the outer rigid ring is made in the form of an outer flange with the possibility of installation on the outer side of the air chamber of the shell of the supporting structure, and the butt connection of the inner and outer flanges along the plane of the flanges mating forms a flange connection, and the formed flange connection is made rigid and tight.

EFFECT: ensuring the necessary tightness and equal strength of not only the connection itself, but also the tightness and reliability of the pneumatic structure.
