MULTIPLE-LAYER WALL AND ITS MANUFACTURE Russian patent published in 1997 - IPC

FIELD: civil engineering. SUBSTANCE: this can be used in construction of low-storied buildings for dwelling, social and industrial application. Multiple-layer wall has internal warmth-keeping layer made with uniformly located through-holes for creating concrete keys in them, and external concrete layers which are connected by rod links passing through warmth-keeping layer and by reinforcement bars located in concrete keys and also by rigid spacious framework. Wall is additionally provided with at least two technological rods which are parallel to each other and installed above and adjacent to warmth-keeping layer, and also with flat reinforcement net installed above technological rods with clearance as to warmth-keeping layer at its both sides. Method for manufacturing multiple-layer wall starts with formation of rigid spacious framework with nets for connection of concrete layers and with connecting members. Then installed in framework is warmth-keeping plate. Framework is fixed on foundation and applied to framework by guniting are internal and external layers of concrete or gypsum mixture. Framework is formed in horizontal position with dimensions of one storey with counting of wall thickness, and simultaneous location of warmth-keeping layer in it. At formation of framework, warmth-keeping plate is strengthened by connecting members. EFFECT: high efficiency. 3 cl, 3 dwg
