STRUCTURE OF A CRAWLER REINFORCED CONCRETE BEAM OF THE SPIDED STRUCTURE OF THE OPERATED ROAD BRIDGE

摘要

The utility model relates to the field of bridge construction and can be used to increase the reliability and load-carrying capacity of reinforced concrete beams of superstructures of operated road bridges. The technical task of the PM is to develop such a structure for a strut reinforcement of a reinforced concrete superstructure beam of an operated road bridge, which will ensure an increase in its reliability and carrying capacity, as well as at the same time, a decrease in the labor intensity of work on its reinforcement, performed in the bridge span. The indicated technical problem is solved due to the fact that the structure of the strut reinforcement of the reinforced concrete beam of the span structure of the operated road bridge consists of two steel pipes of the same gauge and diameter, channel sections and two corners, differs in that the upper ends of the pipes converge in the middle of the lower chord of the beam, where the section of the channel is located, rigidly attached to the chord of the beam with anchor studs, and the lower ends of the pipes are supported on the foundations of both supports pr The bridge span through the sections of steel corners rigidly connected to the cutoffs of the foundations with stud anchors. The ends of the pipes are rigidly connected to the channel and corners by welding. 1 n. and 1 h. n. f-ly. 4 ill.
