COLLAPSIBLE STRUCTURE FOR THE ARCTIC ZONE Russian patent published in 2018 - IPC E04H1/00 E04B1/343 E02D27/35 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, namely, to collapsible structures erected in difficult soil conditions, including on permafrost soils, and can be used for the rapid erection of residential and administrative buildings, as well as for the rapid dismantling and transportation of such structures to the new location together with the foundation. Collapsible facility for the Arctic zone is assembled on the erection site, with the possibility of its subsequent dismantling and transfer to a new location, in difficult soil conditions, including on permafrost soils. Structure foundation is installed on the vertical displacement mechanisms. Vertical displacement mechanisms are placed on the buried into the ground support elements. Support elements are made in the form of screw piles screwed in into the permafrost soil or the ice mass. Vertical displacement mechanisms are made in the form of jacks, which by their lower part are installed on the supports from the low thermal conductivity material in the form of cups for the jacks reliable fixing. Supports are attached to the screw piles heads. In the cross-section the structure is made in the form of the octagonal shaped three-dimensional block, assembled at the installation site from separate sections having a thermal insulation layer. After its assembly the structure is raised by means of jacks to the required height to form a ventilated underground and ensuring the foundation sections horizontal position and the structure roof relative to the ground level, regardless of the terrain. Jacks position is fixed at the same height with a flat terrain surface or at different heights in case of uneven terrain.

EFFECT: invention allows to reduce the complexity of the collapsible structure foundation creating in difficult soil conditions and the uneven terrain, minimize the heat transfer from the structure to permafrost soil or ice mass, and reduce snow drifts and reduce heat losses during the structure operation in the Arctic zone.
