Concrete beam animal shed floor reinforcing wire lattice - has short straight bars linking upper chord and long curved bars for lower

摘要

The reinforcement comprising a welded wire lattice girder, is esp. for grid-connected trapezoid or T-sectioned concrete beams used in animal shed floors, with gaps. The T-sectioned girder has one lattice structure (10) connecting its upper chords (5, 8, 9) to absorb secondary shearing forces, made up from short straight bars (10) welded together. A second structure (11) between these bars absorbs primary shearing forces, with long intersecting welded bars, which are curved, to run towards the main girder axis (15), intersecting this at an angle (a) and bearing the lower chords (6, 7) at their ends. Here they are welded so that the bottom chord assembly fits into the beam centre axis corresponding to the main girder axis.
