How can I tie in these joists to prevent ceiling bend?
Anonymous user 23/02/2024 - 3.02 PM
Hi, a few years back we removed a wall between our kitchen and living room. We were told the wall / beam wasn't load bearing. Since then we can see that its bending and there is an obvious dip in the bedroom floor above. I've lifted up the floor boards above and the joists are not continous from each end of the house and meet above this beam. They are not even lapped together and lie about 4.5 inches apart. I'm looking for the best approach to tie in the joists together or an other method to make this safe. I have pictures to help describe and I can e-mail them over if interested.
Are you a tradesperson and able to answer this question?

I'm assuming the joists are minimum 6x2? get some acro props and a scaffold board or 2 depending on length of the run. Take the board or boards and place under the beam and tighten acros underneath till the bow is level. Then from up top take the floorboards up and use same size timbers with a minimum of 1ft and half overlap on both sides front and back of exsisting timbers and clamp. Then use 4 inch timberlocks and splice. I would reccomend 4 or 5 on each splice. As long as it's level should have no more issues.

The fact that your floor joists use to end above the old wall and beam and are not tied together would indicate that you have taken down a supporting wall. When floor joists are supported by a wall they are not then tied together and are offer set at different centres which sounds like what you have. I would highly recommend you getting in a builder or structural engineer to have a look ASAP! These floor joists will need to have a support reinstalled. A rule of thumb when working out joist strengths is to measure the span in feet then divide by 2 and add 2 so if you have a 20-foot span divide 20 by 2 =10 +2 + 12 you will need 12x2 joists.
