METHOD TO MANUFACTURE LARGE-SPAN COVERS OF HANGAR, LARGE-SPAN COVER OF HANGAR (VERSIONS) Russian patent published in 2012 - IPC E04B1/32 

FIELD: construction.

SUBSTANCE: hangar cover is assembled at the level of construction site surface. One half of pillars is manufactured as movable, and the other half of pillars remains fixed. Then in the assembled form ropes are used to envelope a hangar cover in the plane of cover trusses, giving it construction lift, besides, in the lower belts of trusses pre-stressing is pulled in these ropes by means of ties from ropes, as well as in bearing structures of the cover, and the cover is fixed in this position, for this purpose each movable pillar is installed into design position, using for this purpose lifting mechanisms as well. After that along the external contour of pillar foundations with the help of ties from a system of bearing ropes, pre-stressing is arranged in these ropes, and they are fixed in the bearing support units, then the hangar cover lifted at pillar height is fixed on foundations, and lifting mechanisms are dismantled. Two more methods to manufacture a hangar cover are proposed.

EFFECT: reduced material intensity and labour intensiveness in assembly of hangar cover.
