FIELD: construction.
SUBSTANCE: disclosed group of inventions relates to a lining device and a method of attaching facing elements to a support structure. It is used for protection of surfaces and/or structures in installations, which during operation are subject to considerable wear under influence of material, treated with plants, such as chutes, drums, bins, feeders, loading buckets, reloading platforms and transport platforms, such as truck bodies, in stone-working, mining industry, in production of dry mixtures and erection of structures. Wear protection device comprises at least one lining element, made with possibility of attachment to support structure, and at least one device containing first element, made with possibility of arrangement in through hole of specified at least one facing element or through hole formed by adjacent facing elements. Said through hole has first circumferential size along first part in its axial direction and second circumferential size along second part in its axial direction. Second circumferential size is smaller than first circumferential size, and in transition area between said first and second portions of through hole support surface is formed, second element is intended for interaction with first element so that at mutual connection of first element and second element there is attachment of said at least one facing element to support structure. On external periphery of the second element there are grooves intended for interaction with auxiliary tool. Method of attaching facing elements to support structure includes arrangement of hole of facing element or hole, formed by adjacent facing elements, above attachment location on support structure, providing interaction of first element with support structure and providing interaction of second element with first element by introducing auxiliary tool into interaction with grooves, made on external periphery of the second element, and provision of twisting movement of the second element with attachment of the facing element or facing elements to the support structure.
EFFECT: technical result is higher efficiency of protection against wear, as well as easier and faster installation and dismantling of separate facing elements.
