LINEAR SYSTEM OF SURFACE CASING Russian patent published in 2014 - IPC E04B9/26 

FIELD: construction.

SUBSTANCE: invention relates to the surface casing system, and more specifically. The improved linear system of surface casing includes a plenty of linear media; plenty of strips attached to them, in this case each strip has a rear surface, first and second grooves extending therein and entering into strips, besides the grooves are multidirectional and each one is formed by means of the first cut extending from the rear surface of the strip inwards and outwards, and the second cut extending from the first cut in the inward direction, in this case tooth is formed in the wall of each of the grooves, besides the tooth has a first surface portion which is inclined downwardly and outwardly and a second surface portion which is inclined downwardly and inwardly; and a plenty of spring clips which attach strips to linear media, in this case each spring clip has the first and second projections which are angled towards each other, besides each of the projections comes into contact with the respective tooth, besides when pressuring against each of the clips in the normal direction to the back surface of strip, the projections are bred, and each of the clips latches in the position in which the projections seat in multi-directional grooves, in this case each projection has a shape substantially corresponding to the shape of teeth, formed in the walls of each of the grooves.

EFFECT: improvement of linear system of surface casing.
