SET OF SECTIONS OF MAINLY LIGHT-TRANSMITTING GUARD OF BUILDINGS AND STRUCTURES Russian patent published in 2000 - IPC

FIELD: construction and manufacture of building structures and articles; applicable in manufacture of sets of sections for front guards and facing of buildings and structures including showcases, separating partitions, etc. SUBSTANCE: set of sections has hollow load-carrying post or hollow cross-bar with at least two longitudinal ribs protruding beyond the contour of load-carrying post. Ribs have flanges at their ends with longitudinal recesses and box-section rib located between them. One of bases of box-section rib is combined with flange of U-shaped rib in whose hollow expansion anchor in the form of insert is fixed. Hollow expansion anchor has hollow for location of fastening means, pressing strip with sockets on sides for polymer seals, flexible cover fixed in sockets and embracing the pressing strip from outside. Installed in longitudinal recesses of flanges of a pair of ribs of load-carrying post or cross-bar are fluted sections-guides with curves, mainly, cylindrical internal surface on which sliding strips with recesses for accommodation of seals and with bearing surface corresponding to curvature of fluted sections-guides. Pressing strip is fixed to T-shaped seal of polymer material whose post has protruding latch introduced into hollow for location of fastening means of expansion anchor in the form of insert. The protruding latch is confined on sides of cantilever parts of T-shaped seal exceeding its length at least by factor off 1.5. Each cantilever part is made in the form of plate separating hollow over its full length or its larger part between sections and guard. Seals located in longitudinal recesses of sliding strips are made with at least one special member separating hollow between sections and guard, over its entire length or on its larger part, into additional, mainly isolated spaces. Seal special member is located so that it allows its introduction between plate of T-shaped seal and inserted expansion anchor. Fluted sections-guides of one of edges cone in contact with U-shaped rib. EFFECT: extended possibility of variation of forms of structures with minimization of used structural members and joining units ensuring the preset position of guard structures and observed high requirements on heat insulation. 2 cl, 2 dwg
