Frame partitions (Part 2)
Designs of partitions from gypsum plaster board sheets can be of various types: with a single-layered covering on metal skeleton; with two-layer covering on the metal skeleton; with a three-layer covering on metal skeleton; on the double metal skeleton; on the double metal skeleton with space for communications.
The given constructive types allow erecting a partition with a demanded level of sound insulation and fire resistance. For example, “KNAUF” develops tables with comparative data on fire resistance of various designs???????? partitions - on a metal and wooden skeleton with coverings from usual and fire-resistant gypsum plaster board sheets with thickness of 12,5 mm. and also the table of settlement characteristics of sound insulation of multilayered partitions from gypsum plaster board sheets. Use of the given tables facilitates the choice of the constructive decision.
It is necessary to remember, that in case of the raised humidity (bathrooms, kitchens, bathing) it is recommended to use water-resistant gypsum plaster board sheets, thus it is necessary to consider, that in places of direct hit of water on walls it is necessary to cover a surface of sheets with waterproofing coat.
The admissible height of a partition from cover sheets (the average thickness makes 12,5 mm.) depends on the sizes of cross-section section of used structures and distance between them in a skeleton of a partition, and also from its constructive decision. The height of a partition on a metal skeleton can start from 5 - 6,5 m (weight of one square meter makes 25 - 49 kg). The partition on a wooden skeleton (wooden bars with section of 60?????80 cm.) can have height up to 4,1 m (weight of one square meter can vary from 30 up to 50,5 kg).
Installation of gypsum plaster board partitions should be done during painting and decorating, up to the device of pure floors when all “wet” processes are finished and executed distributing electro technical and sanitary systems, in conditions dry and normal humid mode and temperature not below +15????????.
