BENDING PROCESS OF CORRUGATED SHEET, BEARING STRUCTURE PRODUCED ACCORDING TO THIS PROCESS AND MODULAR ASSEMBLING OF SPECIAL-SHAPE BEARING STRUCTURES PRODUCED ACCORDING TO THE INVENTED PROCESS INTO METAL TENT

摘要

The invention refers to a process of bending corrugated sheet (3) made of metal, especially sheet metal, sheet alloys or other materials. The essence of the invention is warping of sheet by means of impression of pattern into its underside, which results in its bending. According to the process, arched bearing structures (2) are produced, exhibiting increased bearing capacity, withstanding higher loads and keeping a stable shape. Bearing structures (2) of the same shape can be modularly assembled together and are applicable for overroofed shelters, canopies, facade claddings, facade understructures, bearing structures and similarly. Arched bearing structures (2) of specific shape can be used as basic segments (G) for modular construction of metal tents (1) the components of which are also protection walls (15) and fixing elements (16). Metal tents (1) are mobile, weather-resistant and suitable for transport and can be used for housing people and animals or for storing plants, various supplies, vehicles, goods and other objects of all kinds in cases of natural disasters.
