SKYLIGHT BRIDGING OF BUILDING STRUCTURE, COVER OF SKYLIGHT BRIDGING HATCH AND HATCH COVER PROFILE

摘要

FIELD: construction.;SUBSTANCE: inventions relate to the field of construction, in particular, to skylight bridgings equipped with hatches. In the skylight bridging there is a hatch with a cover, one part of which is rotary, and the other one - flapping. The hatch neck is made as a through opening limited along the perimeter with rectilinear bearing metal shapes bent along the radius and pressing planks. At least one support bracket of the cylindrical hinged element of the hinge is fixed between one of rectilinear shapes and its pressing plank. The response cylindrical hinged element of the loop is made in the form of an element of the rectilinear bearing metal shape of the rotary part of the cover and is equipped with a slot for the hinged element of the support bracket of the hinge. Hinges form the hinged connection by means of the common axis. The hatch cover and its profile are proposed.;EFFECT: increasing operational reliability of skylight bridgings.;11 cl, 13 dwg
