Double shell reinforced concrete hall slab mesh - has triangular lattice girder connectors and anchor bars between chords and zigzag struts

摘要

The prefabricated double reinforce-concrete shell is used in wall erection, with steel mesh in each shell, zigzagged connector linking meshes and anchor bars between bends and meshes. The connecting element is made from a triangular lattice girder with upper chord bar (11) parallel to the lengthways rods (31) in one mesh (3), and two lower chord bars (12, 13) parallel to, the lengthways rods (21) in the other mesh (2), together with two zig-zagging diagonals (17, 18). the anchor bars (4, 5) are led through the openings (14 -166) bounded by the bend points in the diagonals and the chord bars.
