undue strain on lifting equipment and could also damage adjacent slab edges thus requiring more repair and added cost with the beveled saw cut the broken slab pieces are easily removed as a single unit in the removal process the concrete anchors 9 are installed with a minimum of one in each separate broken piece of slab after the anchors are set the beams 3 and 4 can be placed such that all anchors are directly under some portion of beam connector pins 7 and either all thread 8 as shown or coil rod 14 can be inserted and using plate washer 10 and nuts 11 or 15 the attachment can be tightened down the combination of connector pins and attachment devices pulling down create forces on the beams 3 and 4 which naturally lock all parts into position at this point the slab can be rigged to crane fork lift of various other pieces of equipment and removed u2014 as a single unit the unit can be placed on a truck and removed out of the work zone and the installation process can now begin many rigid pavement designs call for steel reinforcement between adjacent slabs and many do not.
