FIELD TESTS OF THE EXPERIMENTAL CONSTRUCTIVE SCHEMES OF SOUND INSULATION OF THE FLOOR

Abstract

The dynamic development of urbanization in Ukraine, as well as throughout the world, only increases the number of noise sources that disturb people. And this cannot be ignored, because insufficient sound insulation in an apartment threatens people with neuroses, changes in biorhythms, disorders of the digestive system, headache, memory impairment, problems associated with the perception of color. Therefore, you need to pay maximum attention to the sound insulation of premises during the construction of residential buildings. One of the main disadvantages of monolithic reinforced concrete multi-story buildings is noise. Penetrating into the apartment, he becomes the cause of irritation, an obstacle to sleep or concentrated work. It's no secret that high-quality soundproofing of premises plays an important role in our life and is necessary for our comfortable well-being. This article is devoted to solving an important issue of soundproofing floors in monolithic reinforced concrete multi-story residential buildings, namely from impact noise. The article discusses structural and technological schemes for sound insulation of a floor of three types, using various materials and their combinations to achieve the regulatory requirements for sound insulation from impact noise. When choosing the most rational structural and technological scheme, the results of a comparative analysis of organizational and technological indicators for the device of soundproofing the floor were used, as well as indicators of the reduced impact noise obtained as a result of full-scale tests. Full-scale tests were carried out in houses under construction. The technology for performing each type of floor will depend on the chosen structural and technological scheme, and in the future, the comfort of the residents of the apartment. Comparison of the structural and technological schemes in the future will allow to study and develop a modern and highly efficient structural and technological scheme of the floor sound insulation structure.
