Estimate of Operational Efficiency of Coating of Combined Insulated Roll Roofs
At present, the largest share of constructed buildings is residential houses with bearing reinforced concrete structures of roofs (pre-fabricated or monolithic), that’s why the development of an efficient structural-technological scheme of a combined insulated roll roof is an actual task. The results of full-scale studies of technical conditions of operating combined roofs from melting bituminous-polymer roll materials are presented; main reasons for the appearance of leakages in roll roofs are defined. With due regard for technical normative legal acts acting in the Republic of Belarus and the Russian Federation, proposals concerning the efficient structural-technological solution of combined roofs are made. Recommendations on the use of claydite gravel instead of dry mixes for making roof pitches make it possible to significantly reduce the loading on bearing structures of the combined coating and improve the level of mechanization of work execution. The list of PVC-membranes, produced in the Russian Federation and other countries presented in the article, and considered technological solutions of fastening of PVC- membranes to the base of the combined coating are the base for designing combined roofs. The conclusion about reasonability to use PVC-membranes for arrangement of roofing coating instead of melting bituminous-polymer roll materials is made.
