We have previously had field problems where due to carelessness the anchor bolts were stepped on or kicked before the concrete hardened. We instructed them to bend the rods into position. If this did not work we told them to drill and grout in new rods. ---------- From: Brent Koch[SMTP:brentk(--nospam--at)tdl.com] Sent: Monday, May 11, 1998 12:06 PM To: seaoc(--nospam--at)seaoc.org Subject: Crooked Anchor Bolts I have this current condition at a jobsite: We are using 1-3/8" diameter A449 anchor bolts to connect several precast mansard to a parking garage. A bolted connection is used along six ramp bays where our panels are bolted down directly to the tops of the columns at constant elevation. (The roof slab is continually changing elevation along these bays.) Here, pairs of anchor bolts extend vertically about 3 ft out of the column and will pass through (2)3-1/4" dia. sleeves in the precast. The sleeve is eventually grouted and mechanical anchorage is provide by a plate and nut at the end of the rod. The general contractor has not placed the rods plumb coming out of the columns. We need the rods plumb to facilitate installation and to permit proper alignment of the panel once the panel is landed. Is it possible to heat this type steel, not in excess of 1200 deg F, to straighten the rods? Comments and references appreciated. Thanks in advance. Regards, Brent Koch, P.E.
