Abstract

The invention relates to the field of construction and is intended to cover civil and industrial buildings and structures. The purpose of the invention is to increase reliability and reduce material consumption. The sprengel truss includes a curvilinear upper rigid 1 and lower flexible 2 casks, vertical rigid pillars 3 and flexible puffs 4. Each puff is connected at the ends, respectively, to the support unit and the lower coping 2 trusses. The flexible fasteners 4 are made curved, facing upwardly convex, and are connected in a flight to vertical rigid posts, for example, by means of sliding ties. 5 il.

Sprengel truss consists of a curvilinear upper rigid 1 and 15 lower curvilinear 2 poles, vertical rigid pillars 3 and additional puffs 4 connected at the ends with a truss support unit and the lower pole 2 with the ability to control 20 forces in them, for example, using tensioning devices 5. In the span of the strut, the strut 4 is connected to the vertical stanchions 3 by means of clamps 6, which allow sliding of the thrust slides 4 without transferring horizontal forces to the strut 3 (Fig. 3 and 4).

Vertical loads perceive the appearance of opposing thrusts, mutually canceling each other. A uniform load is perceived by the mainly compressed-bent upper som 1 and flexible stretched lower som 2. Curvilinear tightening 4, with the bulge facing upward, is only included in the operation of the structure under the action of an uneven load loss of stability of the upper one ca 1 and reducing bending moments in it.
