Аннотация

In modern construction practice, partition structures are often used that do not meet regulatory requirements for airborne noise insulation. This reduces the acoustic comfort and safety of people in the rooms. An urgent task of building acoustics is to find structural solutions for enclosures with the required sound insulation properties and minimum values of surface density and thickness. New design solutions were considered: a lightweight frameless partition with acoustic isolation of the shotcreted claddings and the middle layer; lightweight frameless partition with acoustic separation of layers and fragmented shotcreted claddings. As analogues currently used in the design and construction of civil buildings, lightweight single-layer partitions made of tongue-and-groove gypsum slabs, gas silicate blocks, monolithic gypsum concrete, as well as multilayer lightweight frame-sheathing partitions are considered. A methodology has been developed for assessing the rationality of new design solutions for sound-insulating lightweight partitions in comparison with analogues. At the first stage of the assessment, enclosures that do not meet regulatory requirements for the value of the airborne noise insulation index are excluded. After this, a comparative analysis of the design solutions of the partitions is carried out according to two parameters: surface density and thickness. The results of the completed assessment are presented in tabular and graphical forms. An evaluation of a lightweight partition with shotcreted claddings in comparison with a frame-sheathing partition showed the rationality of the new type of enclosure in terms of surface density. The developed methodology for assessing rationality is recommended for use in the design of civil buildings. This will eliminate the use of lightweight partitions that do not meet regulatory requirements and select rational design solutions without inflated values of surface density and thickness.

2. A graphical view of assessing of the rationality of new design solutions for lightweight partitions with shotcreted claddings in comparison with analogues. Location of the partition: between the bathroom and the living room of one apartment (Rw required=43 dB): – light partitions with new types of shotcreted claddings (see item 1 in Table 1); – lightweight single-layer partitions (see item 2 in Table 1); – light multilayer partitions (see item 3 in Table 1). Partitions for which condition (1) is not met and, therefore, cannot take part in further evaluation are indicated in red; green color indicates partitions for which condition (1) is satisfied and which are involved in further evaluation
