I work for myself, and usually do remodels, but work is slowing, so I did a bid on demo-ing a 35 ft chimney stack. I am the home owner is renting the scafolding for us, my question is, I am assuming it has to be tied to the frame of the house or something, anyone have knowledge on this, I am assuming screwing to the roof is not the way, I would assume taking away part of the siding is the correct way, and attaching it to a stud. How far up and how many places?
Use lead anchors and drill holes in the mortar joints of the stone - then insert the lead anchors. Get correct size masonry drill bit for the lead anchors. Now while you are buying the lead anchors also buy some threaded eye bolts that match the threads inside the lead anchors. Also buy some #9 sticks or rolls of wire. As you set up your scaffolding tie it back to the chimney by cutting blocks of 2 x 4 with a notch in it to fit around scaffold legs (v notch). Now place the blocks between the scaffold legs and the chimney - then tie wire from the eye bolt to the scaffold leg and twist the wire tight so it pulls the scaffold tight to the chimney. Do this about every 10 feet in height. Remove these eyebolts/notched 2 x 4's as you come down from top removing the stone. Make sure you have full walkboards with slide stops screwed under the ends of the boards so they cannot slide off the scaffold frames.
i usually screw in a couple of eye bolts just under the roof line and tie wire it ...if built plumb and level the wire is more psycological than anything...
Check the OSHA requirements, and then use common sense. Attach to the house every section with tiebacks. Make sure the first section is level with adjustable legs on a firm surface.
ive worked off scaffolding some,we just stacked it.didnt ties em off or anything.anyway if possible,youb be better served to use a man lift.start at the top.light taps from inside chimney will break the mortar nicely.
No - do not remove the siding as you will not find any studs there. Siding is generally attached to wood frame houses - slap boards - but not studs and that wouldn't be secure enough anyway. Hopefully the house has a roof overhang - with rafters. You can use 2x4s x 8 feet bolted to your scaffolding and tied into rafters with a 6 inch bolt. Be gentle on the chimney - do not brute force it. My guess is that its very weak (mortar wise) and that the worse is going to be the sand and weak mortar joints. Be sure to use tarps around the foliage - to avoid damage to the ground. Start at the very top and work your way down.
