Project of model building based on welded beams.
The most commonly used type of structures based on welded beams of variable cross section Such structures are very popular due to their simple design, low metal content and consequently low total cost of the project.
This type of construction does not take up much space when transporting. Also it is not difficult in installation of such structures. In this project applicable thin-walled girders to ensure the strength characteristics of the roof with the least weight of metal.
As a rule, the roofing on such buildings consists of standard sandwich panels located on the roof slope. This design has a distinctly braced blocks which to begin installation with. Since the blocks are braced on either sides of the building, the installation could be started from the both sides.
This type of construction is usually used in model building design and constructions with large span.
