SET OF BUILDING BLOCKS Russian patent published in 2010 - IPC E04C1/40 

FIELD: construction industry.

SUBSTANCE: invention refers to production of building materials used in particular in low-rise and frame housing and also during building of civil and industrial projects with high requirements to decorative outer cladding of buildings, heat- and acoustic insulation of rooms, for example of multistorey apartment houses, cottages and other buildings. Set of blocks includes sets of main, corner and aperture blocks containing face layer with thickness A, bearing layer with thickness C and heat-insulating layer with thickness B located between them, they are attached to each other by polymeric bars, at that basic thickness of blocks in each set is chosen discretely either 300 mm or 400 mm, at that relation of thickness B of heat-insulating layer to sum of thicknesses (A+C) of face and bearing layers, i.e. (B:(A+C)) is chosen completed with basic thickness of blocks 300 mm either 0.50 or 0.67, and completed with basic thickness of blocks 400 mm - either 0.60 or 1.00, at that sum of thicknesses (A+C) of face and bearing layers is constant for all sets, at that each set consists of two groups of blocks. Thickness A of decorative layer in each group increases in arithmetic progression according to relation A_i=A₀+10·n, where A₀ is chosen not less than 40 mm, and n is integral number and corresponds to range from 1 to 6, and thickness C of bearing layer decreases in arithmetic progression in each group correspondingly. Blocks in each group are made according to regional weather conditions requirement and are characterised by thickness B of heat-insulating layer being constant in group for region. Each group is provided additionally with belt blocks made one-piece and consisting of face and bearing layers, and with air-exchange block provided with through-hole and ventilating grill rigidly fixed in it. Blocks of corner type are made in two forms, one of them is provided with equidistant L-shaped face and heat-insulating layers, and in cavity of heat-insulating layer shortened bearing layer is located. The other form of blocks is provided with equidistant L-shaped bearing and heat-insulating layers, and in cavity of heat-insulating layer shortened face layer is located.

EFFECT: improvement of universalisation of set of blocks and enhancement of their use in low-rise and high-rise house building under various weather conditions, simplification of technology of walls construction observing all required technical and technological parametres, optimisation of ratio of all layers dimensions, improvement of their strength properties and cheapening of building.
