где α - угол между смежными боковыми гранями несущей конструкции; l - отношение изгибающих моментов на стойку от нагрузок, действующих в разных плоскостях; K1 и K2 - коэффициенты, определяемые из соотношения площадей сечения ребер жесткости и боковых граней стойки опоры, причем a - оптимальный, если напряжения по осям X и Y равны, т.е. . Пирамидальная форма стойки опоры и равновеликие плоскости геометрических форм элементов несущей конструкции, выполненных из одного сплошного металлического листа утолщенного профиля и из элементов обрешетки, повышают механическую прочность несущей конструкции и устойчивость длинномерной стойки. Решетчатые элементы облегчают вес стойки, упрощают монтаж электрической части опоры и ее обслуживание. При установке в проектное положение такая стойка опоры является быстромонтируемой, так как имеет небольшую металлоемкость и эстетичный вид. Для удобства транспортировки длинномерная несущая конструкция может быть выполнена секционно из сплошных фигурно-гнутых полос листового полотна, которые скрепляют при монтаже с помощью фланцевых соединений 5 из уголкового профиля или сваркой. 3 ил. The invention relates to the construction, in particular to the long supporting structures of the type of rack supports the transmission line of low voltage class. The objective of the invention is to increase the stability of the supporting structure of the support of the support in normal and emergency modes by increasing its mechanical strength and carrying capacity while simplifying its installation. The technical solution of this problem is achieved by the fact that the long supporting structure of the stand of the support of triangular section with figured side faces and belts with stiffeners from a bent sheet material is made in the form of a hollow (frameless) truncated pyramid with two adjacent side faces 2 formed from a Y-shaped solid metal sheet in the form of congruent (equal-sized) planes in the form of trapezoids, and one side face with a flat surface formed by elements of the lattice 4, for example, wasps placed along the entire height of this side face and attached to the outer surfaces of flat stiffeners 3, formed by the end bends of the same continuous sheet in the form of parallelograms symmetrically arranged on different sides of the lattice side face along one plane with it and adjacent obliquely at an oblique angle to the planes of two adjacent side faces 2, with the corner belts 1 of the supporting structure being formed by the edges of the bends of this sheet web in the form of three lateral edges of the truncated pyramid, and the optimum value the angle of bending between adjacent side faces of the supporting structure is defined as the ratio of the cross-sectional areas of the ribs and the side faces of the rack by the expression:
where α is the angle between adjacent side faces of the supporting structure; l is the ratio of bending moments to the rack from the loads acting in different planes; K 1 and K 2 are the coefficients determined from the ratio of the cross-sectional areas of the stiffeners and the lateral faces of the support leg, and a is optimal if the stresses along the X and Y axes are equal, i.e. . The pyramid shape of the support leg and the equal-sized planes of the geometric shapes of the supporting structure elements made of one continuous metal sheet of a thickened profile and of the sheathing elements increase the mechanical strength of the supporting structure and the stability of the long stand. The grid elements facilitate the weight of the rack, simplify the installation of the electrical part of the support and its maintenance. When installed in a design position, such a support leg is fast-mounted, since it has a small metal content and aesthetic appearance. For convenience of transportation, the lengthy supporting structure can be made sectionally from solid figure-bent strips of sheet web, which are fastened during installation with the help of flange joints 5 from an angle profile or by welding. 3 il.
