Abstract
A wall exposed to wear has a wear lining composed of a number of juxtaposed wear lining elements of an elastomeric material or of a mix of elastomeric and other wear-resistant materials. The wear lining elements are secured to a supporting surface with fastening means. Two opposite narrow faces of the wear lining elements have V-shaped recesses, which open toward the narrow faces. The fastening means have washers with V-shaped projections, the V-legs of which are inserted into and abut against the bottom wall of the recesses or into shoulders formed in the recesses, after fastening the elements.
Claims19
A wall exposed to wear, the wall having a wear lining formed of a number of juxtaposed wear lining elements comprising an elastomeric material, the wear lining fastened to a supporting surface of the wall with fastening means in the form of bolts and washers, the wear lining elements being plate shaped with two large faces and narrow faces, the wear lining elements in two opposite narrow faces having V-shaped recesses which are open towards said narrow faces and have shoulders or bottom walls, and the washers of the fastening means having V-shaped projections having V legs, the V legs being arranged in the V-shaped recess and abutting against said shoulders or bottom walls after fastening the washers by means of the bolts.
A wear lining element comprising an elastomeric material, for forming a wear lining on a wall exposed to wear, the wear lining element having, in two opposing narrow faces, V-shaped recesses which have V legs and their joint points being adjacent to and open towards the respective narrow faces, said joint points providing recessed portions for receiving fasteners.
A fastening mechanism for fastening wear lining elements to a supporting surface, said fastening mechanism comprising:
- a washer having an annular shape defining a hole with an inside edge and having a generally flat top surface;
- and
- V-shaped projections having joint points affixed on the generally flat top surface of the washer, the V-shaped projections being positioned to leave an access to the top surface of the washer adjacent the hole, such that a threaded fastener can be positioned in said access and extend through the hole for securing the fastening mechanism to a supporting surface, the top surface of the washer adapted to contact an abutment surface of the threaded fastener at a position beyond a top surface of the V-shaped projections.
A fastening mechanism for fastening wear lining elements to a supporting surface, said fastening mechanism comprising:
- a first washer portion defining a hole;
- a first V-shaped projection having a point, the first V-shaped projection being affixed to the first washer portion;
- a second washer portion, the second washer portion being sized to mate with the first washer portion so as to be jointly securable to a supporting surface by a threaded fastener;
- and
- a second V-shaped projection having a point, the second V-shaped projection being affixed to the second washer portion such that, when the first washer portion and the second washer portion are jointly secured to an underlying supporting surface by a threaded fastener, the point of the first V-shaped projection is directed toward the point of the second V-shaped projection.
