Кроме того, эта опора не обладает архитектурной выразительностью , что очень важно дл современ ,ного города.The design of the television support is known, including the barrel and the steeply set braces supported by p & ml of flj The disadvantage of the known construction is that the support at the base occupies a large area within the city, which remains unused. In addition, this tower does not have architectural expressiveness, which is very important for a modern city.

Claims

The disadvantage of this tower design is that its trunk has increased deformability and insufficient stability, especially above the support ring, and also a significant consumption of materials for the entire structure. The purpose of the invention is to increase the stability of the trunk and decrease the material capacity of the tower. This goal is achieved by the fact that in a tower comprising a trunk fixed on the foundation, a support ring connected to the trunk in its lower part, and supporting elements fixed to the supporting ring and supporting the trunk in the vertical direction are last preloaded spacers, with the supporting elements made in the form of prestressed strands attached by one ends to the support ring, and others to the foundation, and diverging to the base of the tower, with the prestressed struts They are installed radially below the level of the support ring. FIG. 1, the image of the proposed tower, .. vertical section; in fig. 2 is a section A-A in FIG. one; in fig. 3 shows the node I in FIG. 1. The tower includes the barrel 1, fixed on the foundation 2, the support ring 3 in the lower part of the barrel and the support element 4 in the form of pre-loaded strands, which are fixed. on the support ring and anchored in the foundations 5. The support element cuts the entire structure in a vertical position. The barrel has a tubular cross-section across and can be made of metal, precast or monolithic reinforced concrete. Inside the trunk can be placed elevators, stairs and the necessary equipment and communications. The trunk ends with a covered viewing platform 6 and a metal antenna 7. The barrel includes prestressed strands 8, diaphragms 9, flexible struts 10, tension devices 11, prestressed struts 12, attached at points 13 and the construction of the cover 14 and 15. The longitudinal stability of the barrel is provided by prestressed strands 8, which are located outside the trunk. The cables 8 are fixed on the upper end of the barrel 1, they descend steeply, rest on the support ring, change their direction and also converge abruptly on the lower end of the barrel 1, connecting with it. In the intermediate sections along the height, the La 1 ton 8 rasters are uncovered by the diaphragms 9 which are connected to the barrel 1. The diaphragms 9 can have a lattice design, as shown in FIG. 2, or made in the form of a double ring. Tigi 8 give the barrel a cigar shape. The pre-stress in the strands 8 is created by one of the known methods, for example electrothermal. At temperature differences, the magnitude of the prestressing in the strands 8 can be adjusted by pushing them to the barrel 1 by flexible struts 10 equipped with tensioning devices 11 (Fig. 3). The flexible struts 10 are fastened to the tails 8 in the middle of the span between the diaphragms 9. In order to reduce the span of the offset 4 and reduce the amplitudes of their oscillation of the extension 4, they are connected to the barrel 1 with pre-stressed struts 12 attached to the ends 4 at the points 13. 4, a cover is laid which is dome-shaped 14 in the central part of the tower, and in the form of a truncated cone 15 along the perimeter. The use of the tower construction increases the rigidity and stability of the trunk, reduces the consumption of materials of the tower, and allows adjustment nor in the case of temperature differences, creates the possibility of placing service spaces at the base of the tower. It also gives it architectural expressiveness, which is very important for a modern city. The invention of the Tower, including a trunk fixed on the foundation, a support ring connected to the trunk in its lower part, and supporting elements attached to the support ring and supporting the trunk in a vertical direction, characterized in that in order to increase the stability of the trunk and reduce the material of the tower, the latter is supplied with prestressed spreaders, and the supporting elements are made in the form of prestressed strands attached at one end 1.w to the support ring, and others at the foundations NTU and diverging towards the base of the tower, wherein the prestressed radially spacers installed below the level of the support ring.
