FIELD: construction.
SUBSTANCE: group of inventions relates to the field of construction and can be used for the manufacturing of high-strength facade thermo panels for facing with heat insulation of wall structures of both newly erected buildings and rundown buildings and structures in housing and civil, industrial, agricultural, transport and other types of construction. High-strength facade thermal panel contains a heat-insulating plate connected to a decorative and protective layer made of reinforced material, equipped with mounting holes for fixing to a wall structure and elements for a "tongue-groove" connection located at opposite end faces of the panel, at that, as the material of the decorative protective layer, fiber-reinforced concrete is used, which is additionally reinforced with fiberglass rods, connection elements are the end face parts of the panel, made in the form of shaped projections and corresponding to them shaped sockets (grooves) over the entire thickness of the thermo panel, wherein the fiberglass rods are located parallel to the width of the thermo panel with an embedding into each connection element. Decorative-protective layer is reinforced with a grate formed of fiberglass rods connected by cross-links. From the front side decorative-protective layer can be made with grooves that imitate masonry grooves with depth of not more than 1/3 of the decorative protective layer thickness. Grooves are additionally located along the thermo panel perimeter or on the thermo panel two adjacent sides. Attachment holes can be located in the grooves of the decorative protective layer and are made two-staged with diameters corresponding to the fastening elements diameters used for the thermo panel mounting. Proposed is a method for a high-strength facade thermo panel manufacturing, comprising the fiber containing mixture preparation to make a decorative protective layer and its laying into a mold for subsequent molding, heat-insulating layer placement into the mold, joining a heat-insulating layer with a decorative-protective layer, molding by vibratory casting in the mold, extraction from the mold and curing, at that, for the decorative-protective layer manufacturing, using a mixture consisting of a binder, a white cement of the M600 grade, additives to the binder in the form of a mixture of mineral substances with high pozzolanic activity selected from the group consisting of metakaolin, micro silica, fly ash, redispersible powder to increase the adhesion of concrete, plasticizer, water, filler in the form of a mixture of quartz powder, fine-grained quartz sand with size of 0.16–0.63 mm, quarry sand 1.0–1.9 mm and iron oxide pigment, in the process of vibration, the decorative protective layer of the thermo panel is additionally reinforced with fiberglass reinforcement, the heat-insulating layer placement is carried out with its simultaneous loading from the top immediately after the fiberglass reinforcement placement into the mold, after which the vibration is turned off, the panel curing in the mold is conducted by a natural drying method for 12–16 hours and a further strength gaining is carried out outside the mold. As fiberglass reinforcement, fiberglass rods are used, which are placed into each connection element in the form of single rods or in the form of a grate formed of fiberglass rods connected by cross-links.
EFFECT: obtaining a thermo plate with high physical-mechanical and operational properties, such as high bending strength, low moisture absorption, high frost resistance, increase in durability (service life), without carrying out of renovation and overhaul in the process of operation; reduction of labor intensity in its manufacturing and installation both due to the thermo panel shape and weight reduction; as well as obtaining a thermo panel having expressive decorative features.
