UNIVERSAL MOBILE STRUCTURE FOR SHELTER AND PROTECTION Russian patent published in 2025 - IPC E04H15/26 E04H15/32 

FIELD: construction.

SUBSTANCE: invention relates to prefabricated building structures of general-purpose mobile type. Universal portable structure for shelter and protection comprises a support annular base located in the lower part, and a support part located in the upper part, said base and the support part are connected to each other by means of arc-shaped elements forming a combined dome-shaped protective frame, at that, located in the upper part of the structure the support part is made partially movable, consisting of two arranged one above the other disc annular elements with transversely mounted stiffening ribs, wherein one of the ring-shaped elements is stationary, to which the arc-shaped elements are attached by one of their ends, and by the other ends are fixedly fixed in the base region with the formation of a stationary segment of the dome-shaped frame, wherein arc-shaped elements are attached to the restrictedly rotating other annular element, which, due to the mobility of their installation at their opposite ends in the base area, form a non-stationary segment of the dome-shaped frame, configured to move above the stationary segment of the dome-shaped frame, wherein said rotation of one annular element relative to other is provided by its sliding by means of eccentric connection.

EFFECT: providing compensation of thermal expansion and inaccuracy of assembly of the structure, which in combination allows efficient and reliable operation of the structure regardless of the impact of climatic conditions during use.
