COLLAPSIBLE STRUCTURE Russian patent published in 2022 - IPC E04H1/12 E04B1/343 

FIELD: construction industry.

SUBSTANCE: invention relates to the building of structures, in particular collapsible dwellings or shelters based on a set of construction modules of full factory readiness, and can be used in extreme conditions in hard-to-reach areas of the country for civilian and military facilities. A collapsible structure contains a set of building modules in the form of sandwich panels of walls, floor, ceiling cover/roof, having connecting elements for attaching panels to each other when forming a structure into an operational position. The floor panel is made in the form of a lower pallet for laying wall panels during the formation of a transportation package, the ceiling covering panel is a roof in the form of an upper pallet for closing the lower pallet. Supports are made on the outer surface of the lower pallet to install the structure in an operational position, grooves are made on the outer surface of the upper pallet panel to form an interface with the supports of the lower pallet of the next transport package when forming a group of transport packages stacked sequentially in height. The outer surfaces of the panels of the lower and upper pallets are made in the form of cylindrical surfaces congruent in the radius of curvature with the formation of a convex surface for the upper pallet and a concave surface for the lower pallet, while the radius of curvature of the forming cylindrical surfaces of the pallets corresponds to 230-700 (cm) with a thickness of the insulation of the panels of the pallets 100-200 (mm) and with a width of the pallets 220-240 (cm).

EFFECT: when implementing the invention, the operational reliability of the structure increases both in the mode of the formed structure and in the mode of transporting packages of building modules to the zone of formation of structures.
