3.8 Facade cladding and roofing structures with textured and other finishes, thin-walled galvanized elements of load-bearing structures, fasteners and parts of load-bearing and enclosing structures, shaped elements of facade and roofing, insulation and vapor barrier materials should be stored in an unheated warehouse with a hard floor covering. Storage of structures, cladding panels and parts in a warehouse is carried out in a packaged form on wooden beams up to 10 cm thick, with a step of 0.5 m. The warehouse must be closed, dry, with hard flooring. It is not allowed to store the structures, panels and parts specified in this paragraph in open areas and together with aggressive chemical products.
3.9 During storage, structures should be sorted by brands and stacked taking into account the sequence of installation.
3.11 To ensure the safety of wooden structures during transportation and storage, inventory devices (lodges, clamps, containers, soft slings) should be used with installation of soft gaskets and linings in places of support and contact of structures with metal parts. Structures should be stored under a canopy to protect them from exposure to solar radiation, alternating moistening and drying.
3.12 Prefabricated structures should be installed, as a rule, from vehicles or enlargement stands.
3.13 Before lifting each mounting element, it is necessary to check: compliance with its design mark; the condition of embedded products and installation marks, the absence of dirt, snow, ice, damage to the finish, priming and painting; availability of the necessary connecting parts and auxiliary materials at the workplace; correctness and reliability of fastening of load-handling devices. Each mounting element must be equipped in accordance with the PPR with scaffolding, ladders and railings.
3.14 Slinging of mounted elements should be carried out in the places indicated in the working drawings, and ensure their lifting and supply to the installation site in a position close to the design one. If it is necessary to change the places of slinging, they must be agreed with the organization - the developer of the working drawings. Lifting operations with thin-walled galvanized structures, facing panels and slabs should be carried out using textile tape slings, vacuum grippers or other devices that prevent damage to structures and panels.
