Abstract

Implementing the modern technological methods is recommended in the article, as well as performing some operations. It should be considered that small and medium-sized enterprises involved in the construction of industrial and civil facilities are also installing the roof coverings. The algorithm of technological operations is as follows: preparatory work; gluing a two-layer waterproofing roofing on freshly formed reinforced concrete panels; double rolling of the uncooled roll roofing after removing the panel from the steam chamber. The process of installing the waterproofing roofing has to be carried out in a specially equipped enterprise area. It is recommended to use the following domestic and foreign tools and equipment for above-mentioned operations. Such equipment is a truck crane (for example, KS-45717), a roof crane (KL-3), a temporary fence, a metal ruler, a tape measure, roller or a brush, a scraper, a roofing knife and a roller (weight is 100 kg).The rational methods of roofing installation (based on labor intensity) are presented. As was substantiated, the calculation of labor can change while improving the technology and the tools and equipment used. The quality control of operations is described, it involves visual inspections and the necessary measurements performed with a ruler. Optimal organizational and technological solutions, which allow to manage processes taking into account the safety of workers, were obtained. Fulfilling the labor safety requirements during construction (part 1 and part 11) is primary while installing the roll-up waterproofing roofing made of melting roofing material with the help of a solvent. In addition, it should be noted that the workplaces and storage locations with flammable materials and substances have to be provided with a portable fire stand, as well as with fire extinguishing and medical equipment. The conclusions and recommendations on organizational and technological solutions forin stalling the prefabricated roofing from roll materials by using mechanization means are presented. They are intended for developers of organizational and technological documentation, including flow charts, work projects, regulations, codes of rules. They will be useful for students, masters, graduate students studying for professions related to the production of building, erection and special works.
