STEEL REINFORCED CONCRETE STRUCTURE WITH BALLASTLESS BOARD OF TRAFFIC AREA AND METHOD OF ITS ERECTION Russian patent published in 2011 - IPC E01D2/02 

FIELD: construction.

SUBSTANCE: novelty is the fact that metal beams are an integral part of a reinforced concrete board and are arranged between main beams in the level of upper belts of main beams. On the vertical ribs of the main beams there are detachable tables installed with adjustment attachments, on which the metal beams rest. Upper belts of metal beams are combined by horizontal gusset plates with the upper belts of the main beams, and vertical walls of the metal beams are combined by means of vertical gusset plates with vertical ribs of the main beams. The method to erect the above-described steel reinforced concrete structure consists in installation of main beams, assembly of adjustment attachments on the main beams, resting a reinforced concrete board on the, balancing reinforced concrete beam position along the vertical line with its further fixation on the main beams. The novelty is the fact that previously detachable tables with adjustment attachments are fixed on the vertical ribs of the main beams, the metal beams of reinforced concrete boards are arranged between the main beams and are lowered until they rest on the detachable tables with adjustment attachments. Upper belts of metal beams and upper belts of main beams are arranged in one level, and after balancing of reinforced concrete boards along height with the help of adjustment attachments, position of reinforced concrete boards is fixed. Afterwards the detachable tables with adjustment attachments are dismantled.

EFFECT: increased operational reliability.
