ANTENNA SUPPORT OF TOWER TYPE Russian patent published in 2016 - IPC E04H12/10 E04H12/22 E02D27/42 

FIELD: construction; radio engineering and communication.

SUBSTANCE: invention relates to antenna tower supports of tens of meters height for installation in its upper platform antenna and feeder devices of radar stations. Antenna support comprises four-sided steel tower of truss structure with angular support stands. On lower ends of stands support couplings are welded with holes for mounting stands on gratings. Grating frame is made of channel-type metal beams or H-beams fitted upon screw pile heads at height of 0.5 to 1 m above ground surface. Length of piles is selected on condition of embedding their support screw blades into strong ground below level of seasonal freezing and melting of soils at place of tower installation. To reduce vertical motion of piles and exclude hazardous inclination of support tower under action of force of seasonal soil heaving, stem of each screw pile on outer side is coated with layer of non-freezing coating, its inner cavity is filled with cement-sand mixture, and screw blades are made supporting. Metal beams of grating are connected with support stands of tower and with heads of piles by means of support-thrust connecting elements (STCEs). STCEs are configured to fix parallel attachment of grating beams and simultaneously, to use STCE upper surfaces as horizontal supports for vertical support posts of tower, as well as to displace STCEs along grating beams, when mounting and centering support posts of tower thereupon.

EFFECT: higher efficiency of erection of antenna tower-type supports with simultaneous increase of their resistance to wind loads and seasonal soil movement.
