In the production of interior finishing work, inventory tables, scaffolds, towers and step-ladders are used. For outdoor work, retractable and telescopic towers, mobile lifting units, 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 — with tables-towers and universal collapsible mobile scaffolds, and in rooms with a height of 6-8 m — with mobile collapsible towers and mobile tables-towers; in rooms with a height of no more than 4 m, inventory step-ladders are also used.
Along with this, a number of organizations have developed and implemented scaffolds and tables, which are somewhat different from the well-known.
Inventory scaffolds by G.P. Maslennikov are convenient for plastering. They consist of uprights, purlins and deck boards. The scaffold post consists of two pipe sections that are inserted into one another. A cross is attached to the lower part of the outer section of the pipe (support post), and a hole for the retainer is made in the upper part of it. The inner (retractable) pipe section in the upper part has a fork, and along the entire length, every 100 mm, there are holes for the retainer. Wooden purlins with a section of 100X200 mm are inserted into the forks of the posts, on which the floorboards are laid.
Universal prefabricated scaffolds (USP), assembled from elements Constructor-1 (author VL (three sizes of frame elements: 1X0.6; 2X0.6 and 3X0.6) and auxiliary (horizontal posts, braces, crossbars, shoes, trolley, floor panels) interchangeable parts, from which more than 60 options for various scaffoldings can be assembled.
Sewerage cleaning today is an acute problem because the normal functioning of the sewage system is one of the factors for the successful operation of any system.
The main and auxiliary structures are in the form of a flat welded frame or bracket. The lower part of the struts has a pin for vertical assembly. Horizontal and diagonal ties are inserted into special earrings, which are equipped with all elements.
