REINFORCING CAGE FOR MULTISPAN REINFORCED CONCRETE BEAMS Russian patent published in 2017 - IPC E04C5/04 

FIELD: construction.

SUBSTANCE: in a cage for reinforced concrete beams with a rectangular contour containing faces from flat frameworks made of mutually perpendicular rigidly fixed longitudinal and transverse reinforcement rods, the feature is that it is made with the possibility of perceiving an increased load with multispan reinforced concrete beams, while the flat cages of the lateral faces have a zigzag transverse reinforcement integral along the entire structure span, with a certain pitch and inclination of the branches formed as a result of winding reinforcing rods on the projecting ends of the transverse reinforcement rods of the upper and lower flat cages.

EFFECT: increasing the strength, the crack resistance and the durability of multispan reinforced concrete beams, increasing the strength of inclined sections in the areas near the supports of multispan beams, reducing labour intensity, energy intensity and material consumption while manufacturing reinforcing cages for multispan reinforced concrete beams.
