FIELD: construction. ^ SUBSTANCE: invention is related to the field of construction items production. Method for production of decorative facing material includes moulding of concrete mix and bulge forming on its open surface. At that moulding includes placement of concrete mix in mold and its vibrocompaction. At that in process of vibrocompaction water loss of concrete mix is retained and prevented from its leaking from sections. Then preliminary leveling and removal of concrete mix surplus is done in mold so that mold occupation with concrete mix is at the level of sides height, afterwards mentioned bulge forming, and then - cutting of molded concrete mix into products. Then products are dried in mold for about a day, stocking several molds one on another. Mold for production of decorative facing material comprises sides, which have identical height. At that they are made of metal bars of square section with the side of 10 mm and are rigidly fixed on lower plate with size of 625?500?1 mm from metal-roll sheet. At that sides and lower plate form two identical rectangular sections of mold. Along the whole length of two sides installed on mold sides, two extensions are installed parallel to each other, every of which is made of metal strip with thickness of 1 mm and width of 20 mm. ^ EFFECT: method simplicity and increased efficiency of device. ^ 19 cl, 8 dwg, 9 ex |
