| Special column forms  Every day the largest city of the largest country in the world is threatened with gridlock. The infrastructure of the present-day traffic system can no longer cope with the increased number of vehicles. The urban administration of Moscow resolved to upgrade the traffic arteries connecting the inner city to satellite towns. Greater Moscow ("Oblast") has a population of over 7 million. Up to now the city of Ljuberzy, 2 km south east of the Moscow roundabout traffic, has been reached by means of an urban motorway. Local and district streets run parallel to this route. The second largest connecting road, an extension of the Komsomolsky Prospekt is now being expanded. Traffic will now be routed over a newly constructed bridge, 1, 737 km long, where both of the lanes will be structurally separated from each other. The construction is being carried out by LLC TransKapStroy (Moscow).A distinctive feature of the architecture is found in additional connections for the stairways: two for each lane, which reach from the bridge to the ground in three stages. However, the form of the stairway columns is so sophisticated that standard solutions were out of the questions. Stairway columns are manufactured locally by filling a prefabricated form with concrete. However, when these have the form of a symmetrical hexagon (the cross-section is similar to the silhouette of a clam) and all 36 props must have a height of 2.00 to 6.50 meters and everything must proceed correctly and efficiently one certainly needs good advice. The Paschal representative office in Moscow assigned to the main factory in Steinach (Germany) a contract for the construction of a special form designed to be used repeatedly, which can sustain a pressure from fresh concrete of 80 kN/m². With more than 40 years of experience in metal processing, they created a total of four completely identical sets, each consisting of two extendable, concrete forms, 805 mm wide and 1020 mm deep and with a height of 2.00 and 3.0 m. write your comments about the article :: © 2012 Construction News :: home page |
