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.

Claims

Claim

1. A method of manufacturing lightweight metal structures .X designs, including cutting the walls of a similar workpiece on large bases of a trapezoidal broken line with the formation of protrusions, sliding and joining the obtained elements along the horizontal faces of the protrusions, characterized in that, in order to increase the bearing capacity in the manufacture of trusses from each received protrusion, a triangle is cut from the side of the larger base of the workpiece with the sides parallel to the sides of the protrusion and intersect, which are larger Contents protrusion at points located on the straight lines perpendicular to the longitudinal axis of the workpiece and passing through the smaller base of the projection point.

2. The method according to η. 1, characterized in that the cut line along the large bases of the trapezoid is extended beyond the edges of the protrusions, and the angle formed by the cut triangle is cut vertically to the line of the smaller base of the protrusion, after which the edges of the protrusions are bent to form an / -shaped cross section.
