FIELD: construction engineering. SUBSTANCE: can be used in building new or reconstruction of existing covering of civil and industrial buildings. Covering has monolithic slab, profiled sheathing and reinforcing framework in the form of trusses with upper and lower girths which are connected by struts and/or posts. Profiled sheathing is attached to lower girth of truss. Additional sheets can be fastened to sheathing or reinforcing framework. Application of aforesaid embodiment of covering ensures reduction of amount of metal needed for production, also reduction of own weight, labour-intensity and cost of manufacture together with reduced structural height of covering, easier manufacture and improved quality. EFFECT: higher efficiency. 2 dwg
