The reinforced welding off? Can the channel steel locked with expansion screws be taken out?
1, if you are eager to get down, go to the nearby hardware store, borrow a hand cutting machine, very small, very convenient! 35 minutes away; if you have the time to buy hacksaw ah!2, you find a wrench to remove the nut on the chant, if rust is not turned off, and then go to the hardware store for a grinder, two or three minutes to fix!
The cutting machine can be used to make the welding areas thin and then knock. We used to be like this in the factory. So knock down and nothing will go wrong
Generally speaking, the welding place is stronger than the steel bar itself. If the tool class is concerned, an electric sand grinder is easy to handle. Manual, it is estimated to use a knife slowly.
The reinforced welding can knock down the. Of course, according to the actual situation of welding, adopt the corresponding method. If not all welded, along the side without welding hard hit with a crowbar or poking can. If the whole welding should choose weak side to start, if the first welding scar chisel chisel point mark, and then knock are much easier. There are many concrete methods and flexible use according to the actual situation.As long as the expansion bolts are not corroded, they can be removed. Remove the nut, screw the drop in point, loosen the expansion pipe, pull out, and then pull the screw.
