Experimental Study of the Work of Dowels in Three-Layer Aerated Concrete Panels with a Non-metallic Sheet Coating

New constructions of partitions, made with an inner layer of heat-insulating porous concrete and surface layers (structure) of sheet building elements of non-metallic or composite origin, standard or reinforced with non-metallic composite reinforcement based on basalt or glass roving, obtained by the method of industrial serial assembly of elements on semi-automatic equipment, quickly conquered the market due to the ease and speed of installation, as well as the relatively low cost of construction. However, there are no studies of such panels, which would help engineers implement them more widely in construction and more effectively choose the necessary partition structure for certain premises of buildings. This article presents the results of experimental studies of the operation of metal dowels in three-layer aerated concrete panels with a non-metallic sheet coating. The analysis of the results allows correct and reliable design of dowel fastenings and opens up new questions that require additional research.
