Antiaircraft SLAB building structures, manhole cover slabs and anti-aircraft PROFILE HATCH COVER

摘要

The invention relates to the field of construction and can be used in the manufacture of various, preferably translucent or conditionally translucent building constructions, including roofing equipped with hatches (SAM) overlap, skylights, light domes or other, preferably an arc shape. Technical result - the expansion of the range equipped with hatches of building constructions operating in difficult conditions, including significant external loading, simple to manufacture and maintain, versatile in use, distinguished by reliability, functionality and unification. For this zenithal overlap formed hatch cover, one part of which is made rotatable, and the other hinged, the neck is formed in the form of a bounded perimeter rectilinear and curved bearing metal profiles and the clamping bars through the opening, wherein between one of the rectilinear bearing metal profiles and its clamping strap is fixedly mounted, at least one support bracket cylindrical hinge member, wherein the cylindrical hinge response element cient hinge element is designed as a rectilinear metal profile bearing swivel of the lid and is provided with a slot for the cylindrical hinge member support hinge bracket, wherein the swivel hinge formed by a common axis. The hatch cover, characterized by the presence of rectilinear bearing metal profile rotary portion and the straight supporting metal profile hinged parts united together coupling bearing metal profiles with sealing protrusions, and in contact with the profiles of translucent or conditionally translucent module rectilinear supporting metal profile rotatable and hinged parts includes rectangular cross-sectional hollow stiffener, equipped in its lower s elongated portion sealing projections directed outwards in the middle of its lateral truncated portion of its length is the longitudinal stiffness in a circular groove for fixing the connecting support profiles, the other lateral truncated portion at its upper part is provided with a T-shaped element to form a rotated U-shaped pocket a translucent or translucent conventionally module disposed along the upper portion of the hollow elongated stiffening member, while the lower part is provided with an inclined kronshtey SG cylindrical hinge member, wherein the hole for the swivel axis holds open the entire length of the profile. Profile manhole cover formed integral metal, and a rectilinear bearing - according to the features set forth in the foregoing technical solution. 3N. 5 and ZP f-ly; 13 Ill .; 1 Ex.
