Sound insulation of a wall in a panel house with demountable joints
Popis výsledku v původním jazyce
Classical technologies used in civil engineering are characterized by limited adaptability. Easy disassembling and relocation to another location are practically eliminated. Flexible building systems, that make this possible, are not only favourable in terms of sustainable buildings. These structures are an alternative to traditional prefabricated or monolithic systems implemented in previous years. This solution is more sophisticated in term of sustainability than solutions with rigid non-demountable joints. Problems associated with it arise with regard to guaranteeing the desired properties of such a structure. Many requirements are placed on partition wall structures. The paper deals with the verification of the sound insulation of a partition wall made of reinforced concrete panels with dismountable joints. The principle of the solution of the demountable joints in the vertical heading joint between the panels is described. The heading joint is designed in two variations, which are described in detail. The aim of the structural solution is to ensure meeting sound insulation for use between flats. Furthermore, the fire resistance of the whole structure is necessary to ensure, too. The sound reduction index of the wall depending on the frequency is first calculated using three different methods of computation. Parameters of the used material, namely bulk density, longitudinal wave speed density and loss factor, were measured to ensure reliability of calculations. The results from measurement of the sound reduction index of the two variants of the solutions of demountable joints in acoustic chamber are presented at the end of the paper.
