In the production of finishing work indoors, inventory tables, scaffolds, towers and step-ladders are used. For outdoor work, retractable and telescopic towers, mobile lifting installations, metal scaffolding and string lifts (cradles) are used.When working in rooms with a height of 2.5-2.7 m, two-height tables and universal folding tables are used; in rooms with a height of 3-4 m – tables-towers and universal collapsible mobile scaffolds, and in rooms with a height of 6-8 m – mobile collapsible towers-tours and mobile tables-towers; in rooms with a height of not more than 4 m, inventory stepladders are also used.
Along with this, a number of organizations have developed and implemented scaffolds and tables that are somewhat different from the well-known.
Inventory scaffold G. P. Maslennikov are convenient for plastering work. They consist of racks, girders and decking boards. The scaffold post consists of two pieces of pipes inserted one into the other. A crosspiece is attached to the lower part of the outer section of the pipe (support post), and a hole for the latch is made in its upper part. The inner (retractable) section of the pipe has a fork in the upper part, and along the entire length every 100 mm there are holes for the latch. Wooden girders with a section of 100X200 mm are inserted into the forks of the racks, on which the flooring boards are laid.
Universal prefabricated scaffolding (USP), assembled from elements of Constructor-1 (author V. L. Klimov, trust No. 40 of Glavzapstroy), are used for interior finishing work from 2.5 to 9 m high. All 32 elements of the Constructor are divided into main (three sizes of frame elements: 1X0.6; 2X0.6 and 3X0.6) and auxiliary (horizontal racks, ties, crossbars, shoes, trolley, flooring panels) interchangeable parts, from which you can assemble more 60 different paving options.
Sewer cleaning is an acute problem today.to the normal functioning of the sewage system is one of the factors for the successful operation of any system.
The designs of the main and auxiliary elements are a flat welded frame or bracket. The lower part of the racks has a pin for docking during vertical assembly. Horizontal and diagonal links are inserted into special earrings, which are provided with all elements.
