CERAMIC ARTICLE FOR FACING OF BUILDING STRUCTURES Russian patent published in 1999 - IPC

FIELD: construction materials industry. SUBSTANCE: ceramic article has two face surfaces and is made in the form of briquette with through-holes. Axes of through-holes are located at least in one row, and actually they are parallel to each other between face surfaces. Made in side surfaces of briquette are grooves for dividing of briquette. Axes of through-holes and grooves themselves are directed over width of briquette. Plane of briquette separation crosses surfaces of grooves along generating lines actually parallel to axes of through-holes. It also crosses through-holes. Made in bracket are additional grooves intended for separation of bracket. Additional grooves are located in through-holes over width of briquette along line of crossing splitting plane with surfaces of through-holes. Planes of symmetry of additional grooves are located either in splitting plane or they are inclined with respect to splitting plane. Relation of maximal width of briquette to its length is equal to 0.1-0.8. Briquette can be provided with additional splitting plane which is parallel to main splitting plane. Aforesaid embodiment of ceramic facing article allows for reducing effort needed for separation article together with reduced loss of product due to damage during separation. EFFECT: higher efficiency. 5 cl, 5 dwg
