PRE-FABRICATED HANGAR BASED ON PNEUMATIC FORMWORK Russian patent published in 2021 - IPC E04G11/04 

FIELD: construction.

SUBSTANCE: invention relates to construction and can be used for the construction of pre-fabricated hangars on the basis of pneumatic formwork in the creation of industrial, military and social infrastructure facilities for the purpose of operation in a year-round mode in the northern latitudes of the Russian Federation. The prefabricated hangar based on pneumatic formwork contains the base of the foundation and the shell of the vault, the base of the foundation is made in the form of prefabricated concrete elements reinforced with composite polymer reinforcement with a spacer ring, located on composite screw piles with nozzles for frozen soils. The vault shell is made of a material with a radio-absorbing coating; on the inner surface of the shell, a first heat-insulating layer is sprayed by means of a pump, in which anchor bolts are fixed, and a second heat-insulating layer is applied. A frame made of composite polymer reinforcement is fixed to the anchor bolts, on which a layer of shotcrete is applied to form a rigid structure.

EFFECT: improving operational characteristics of the structure under construction for operation in various temperature ranges, reducing the construction time, reducing the labor intensity of construction, reducing thermal conductivity, reducing the cost of heating the room.
