Abstract
Изобретение относитс к строительству и может быть использовано дл изготовлени из балок двутаврового или швеллерного профил или из листового металла облегченных металлических конструкций типа ферм дл покрытий, перекрытий, галерей и т.п. Целью изобретени вл етс повышение несущей способности при изготовлении ферм. В исходной заготовке 1 разрезают стенку по большим основани м трапеций, образованных трапециевидной ломаной линией с образованием выступов 2. Внутри выступов 2 со стороны большего основани 3 симметрично оси выступа выполн ют вырез 6 в форме треугольника, боковые стороны которого параллельны боковым сторонам выступа, и пересекают большее основание выступа в точках, расположенных на пр мых 7, перпендикул рных продольной оси заготовки и проход щих через крайние точки меньшего основани 4 выступа. Вершину выреза 6 располагают на линии меньшего основани выступа. Образованные полуфермы 8 раздвигают по высоте и стыкуют между собой торцы перемычек 9 с помощью швов. 1 з.п.ф-лы, 5 ил.The invention relates to construction and can be used for the manufacture of I-beams or channel profiles or of sheet metal from beams of lightweight metal structures such as trusses for coatings, floors, galleries, etc. The aim of the invention is to increase the carrying capacity in the manufacture of farms. In the original blank 1, a wall is cut along the large base of the trapeziums formed by a trapezoid broken line to form the projections 2. Inside the projections 2, from the side of the larger base 3, symmetrically to the axis of the projection, a cutout 6 is made in the shape of a triangle, the sides of which are parallel to the sides of the protrusion the larger base of the protrusion at points located on the straight 7, perpendicular to the longitudinal axis of the workpiece and passing through the extreme points of the smaller base 4 of the protrusion. The top of the notch 6 is placed on the line of the smaller base of the protrusion. Formed semi-farms 8 are moved apart in height and joined to each other the ends of jumpers 9 by means of seams. 1 hp ff, 5 ill.
