Rigging for Installation of the Integrated Elements of Metal Structures Steel Retina Television Tower

Abstract

The project of manufacture of works on the construction of a new television tower in Volgograd. The constructive solution of the tower reinforced concrete barrel and the retina. The mark on the top of the spire of 500,000 m, the mark on the top covering 330.000 m, the mark top farm Shukhov 298,600 m, diameter of the bottom 50 meters, on top of 35.3 m. The diameter of the core, constant for at outer edge height and is 12 m, the thickness of the core wall 1 m - from mark m to mark +0,000 +108,700 m, 0.5 m - from the mark +108,700 m to the level of 330.000 m Regularity fragments in terms of 7.5 degrees.. For the installation of the steel retina television tower was completed split into tiers and made the unification of elements of steel structures. Steel retina was divided into X-shaped, X-shaped elements and horizontal elements of the closing. For installation, the rigging was developed, consisting of a yoke, lifting capacity of 25 tons and a universal strut to provide stability and rigidity of the assembled X-shaped elements.
