FIELD: construction industry; production of constructional materials.
SUBSTANCE: the invention is pertaining to construction industry, to production of constructional materials, in particular, to constructional sheathing panels, which are fastened onto a load-bearing framework and are used in house building and other kinds of building-up. The technical result is construction of buildings with the heightened stable resistance to the shearing strain. The reinforced lightweight and resistant to the shearing strain panel capable, while being fastened to the load-bearing framework, to withstand overload shearing strains contains the homogeneous phase gained as a result of solidification of a water mixture of the reactive powders containing (in dry) 35-75 mass alpha hemihydrate of calcium sulfate, 20-55 mass % of hydraulic cement, 0.2-3.5 mass % of lime and 5-25 mass % of active pozzoulana. At that the aforementioned homogeneous phase is uniformly reinforced with the alkali-proof glass fibers and contains the uniformly distributed ceramic microspheres having a mean diameter, approximately, of 10-500 microns (micrometers) or a mixture of ceramic and polymeric microspheres, or is molded from a water solution having weight ratio of water to a reactive powder amounting from 0.6/1 up to 0.7/1, or a combination of both. The panel can be multilayered, at that at least one outer surface of the panel may contain a mature homogeneous stage reinforced wit the glass fibers and containing a sufficient amount of the polymeric spheres for enriching nailability or executed with the ratios of the water to the reactive powders ensuring an effect similar to that of the polymeric spheres, or in a combination with them. The invention also presents the method of manufacture of the indicated reinforced lightweight and resistant to the shearing strain panels. The invention is advanced in the dependent points.
EFFECT: the invention ensures production of the reinforced lightweight and resistant to the shearing strain panels used for construction of buildings with the heightened stable resistance to the shearing strain.
