The disadvantage of this design is its low bearing capacity and rigidity.

The closest analogue in technical essence and the achieved effect is a structural element with increased bearing capacity per unit mass, containing at least two spiral components, each of which has at least three elongated rectilinear sections, rigidly continuously connected in a spiral configuration, at least at least two spiral components have a common angular orientation, a common longitudinal axis and are spaced from each other at approximately the same distance, at least each of the two spirals of the components has continuous filaments of fiber, at least one reverse helical component having at least three elongated straight sections, rigidly continuously connected in a spiral configuration similar to the spiral configuration of at least two spiral components, and having a common longitudinal axis with at least two spiral components, but the opposite angular orientation, and at least one reverse spiral component has continuous filaments of fiber, means for connecting m at least two helical components with at least one inverse helical component at the intersection, providing for the overlap of the fibers of the helical components and the fibers of the inverse helical components in the binder, with at least two helical components and at least one inverse helical component a hollow interior region substantially free of material, and with an opening between them.

The disadvantage of this design is the high complexity of manufacturing.

The technical result of the proposed technical solution is to reduce the complexity of manufacturing beams, an increase in bearing capacity.

The specified result is achieved by the fact that in the beam containing at least two spiral components, said components are made without straight sections and are connected along stiffeners.

Due to the lack of special fastening elements, the beam is easy to manufacture, which reduces the complexity of its manufacture. The absence of straight sections in the spiral components provides a high stability profile of the spiral component, which allows to increase the bearing capacity of the beam. The connection of the spiral components along the stiffeners provides the possibility of obtaining beams of any spatial configuration. The connection can be carried out, for example, by welding, which significantly reduces the complexity of manufacturing the product.

The beam is illustrated by drawings, where in Fig. 1 a general view of the beam is shown, in Fig. 2 is a blank for the spiral component of the beam 4, in Fig. 3 are fragments of the profile of the spiral component, in Fig. 4 is a cross section of the profile of the spiral component.

The beam consists of spiral components 1 (Fig. 1) connected to each other along their stiffeners 2 (Fig. 1). The preparation of the spiral component is a plate of any length 4 (figure 2). The workpiece is twisted in opposite directions: one end of the plate to the left, the other to the right. Thus, two radial stiffness channels 5 (FIG. 3) and two stiffeners 6 (FIG. 3) are formed, twisted along its axis 7 (FIG. 3).

The beam, consisting of spiral components connected to each other by stiffeners, has a load-carrying capacity with increased load-bearing properties. In the blank 4 (FIG. 2), the force vectors F are randomly located. After twisting, the force vectors are ordered, the profile gets a rigid structure and shape. Two stiffening ribs 6 are formed (Fig. 3) and two radial stiffening channels 5 (Fig. 3). They spiral along the axis of the twisted plate and, in fact, form this axis, located at an angle of 45 degrees to it. Channels 5 (figure 3) and stiffeners 6 (figure 3) have smooth wave transitions without straight sections from one angle of stability to the opposite angle of stability. So an imaginary circle 8 (figure 4) closed; there is a uniform distribution of the load around the circumference of the profile of the spiral components that make up the beam. The profile of the spiral component does not have straight sections, therefore it is more stable.

This beam compares favorably with its closest analogues in its simplicity of design, it has a carrying capacity with enhanced load-bearing properties; the connection of spiral components along stiffeners, for example, by welding, significantly reduces the complexity of manufacturing. This makes it possible to widely use beams of this design in construction for the installation of floors of sports, concert, trading floors; peaks, billboards. The beam can be used in the construction of bridges, rail, road, pedestrian crossings; in concrete execution as reinforcement.
