Development of resource-saving technology of arrangement of seam roofing
The article considers the technology of arrangement of a metal pitched roof which is insulated with foamed polyurethane plates and favors the improvement of producibility and reduction in the assembling duration of the roof. This technology means the unification of structural elements of the roof, the transfer of a significant part of operations under the factory conditions that favors the quick assembling of the structure, reduce in cost of work and heat losses and, as a consequence, the improvement of energy efficiency of the building. Installation of roofing is based on the use of dowels and thermoplastic (polyamide) bolted connections, polyurethane panels as basic bearing and enclosing structures which form, due to ribbed surface, ventilation ducts favoring the natural ventilation. The offered technology of arrangement of the quick-assembly seam roofing can be used for buildings with pitched roofs as well as in the course of reconstruction of objects and raising of penthouse apartments, construction of mini-hotels, hangars, garages, recreation centers, children’s camps, temporary or prefabricated housing.
