It is a 1979 unit that I bought a couple of years ago and I recently discovered the issue with the joists when I tore up some damaged sub-flooring. I don't know how long the gap between the joists has existed. I am wondering if I should bolt them at the top to bring them together again, or whether I am better off leaving things as they are. The bottom of the joists are flush but the tops are separated by about an inch.
The floor joists are not bolted together, but are connected with a spike driven at an angle of about 20 degrees from horizontal. If they're through-bolted securely, say 18" on center (I'm not an engineer) I think they'd be quite secure. If you are referring to the mating of the joists of the two halves of the doublewide at the center of the floor structure, it'd be normal for them to be bolted together. I can't tell if the gap you describe has been there since original construction or if it indicates more worrisome ongoing movement. I can say in general that structural connections are very important to prevent a building collapse or to prevent dangerous movement that an open a gas line or rip an electrical wire. What do I do ? leave it as is or bolt the top together ? Reply:Īnon I'm sorry but I don't have a clear enough idea of what's going on with the structure of the doublewide to be confident of an answer. The bottom is flush but there is a gap of about one inch on the top. The center two joists are connected with a long spick at an angle. I have a older double wide and am doing floor repair work.
