METHOD TO ASSEMBLE SWITCH THROWS Russian patent published in 2011 - IPC E01B29/02 

FIELD: construction.

SUBSTANCE: method to assemble switch throws, mostly with reinforced concrete bars, consists of process operations executed simultaneously on stationary benches equipped with an embracing track to move actuators. The method includes delivery of a set of bars with their reference layout, installation of bars by epure and string, laying of gaskets, pads on them, laying rails onto bars, installation of rails by track and ordinates, installation of assemblies of insert and terminal bolts, screwing nuts of these bolts. Process operations are divided into complexes, and they are carried out simultaneously at stationary benches. Benches are installed in the quantity of at least three pieces along the track. On completion of a complex of operations at one bench the actuators are moved along the track to the following bench. From the last bench the actuators are transferred to the beginning of the track to the first bench.

EFFECT: increased rate of assembled switch throws production with preservation of optimal length and width of a flow line.
