Can lally column rest on floor joist.

If the support columns are not placed on proper footings and only rest on the concrete floor it is likely that over time the concrete floor will crack. If there is a lally column in your kitchen living area that runs to the and the basement area has been opened up there needs to be support under the column in the kitchen. Basically 1 3rd of your floor joist is now pointless. You have an l support which puts a lot of pressure on the middle footing which if i can see right is a 4x4 halfway falling off a concrete footer.

There are numerous methods of running the floor joists with respect to the position of the completed girder. They can be found as lally posts lally columns adjustable floor jacks figure 13c or adjustable columns. Obviously is can because yours does. The weight from the floor joists are then transferred down to the basement beams and foundation walls.

There may not be a wall directly above the beam but half of all the floor load on the joists that are tied into the beam is being transfered to that beam. This pad then transfers the weight down to the ground. The beam is then supported by the foundation and the columns below. The floor joists for the second floor will hang off this beam using galvanized joist hangers.

What is a basement floor jack. The area over the beam is a single large room with cathedral ceiling so no load bearig walls rest directly over this beam. The support columns used in floor support systems have multiple terms used to identify them. Girder and joist jacks also known as steel lally columns can be installed at key locations along the structure.

The columns rest on a concrete footing pad below the basement floor. The basic structural principle behind the beams and columns is this the weight of the furniture and people rest on the floor joists. This photo also shows three other beams in the exterior walls. You can do whatever you want to do however with that said it may not be good for the structure of your house.

You and i may have lally columns i m assuming pat has a white fiberboard column with a 3 foot diameter disk of hard candy you can lick for a very long time on it. The column is attached to the footing and extends up to a metal plate screwed to the basement support beam. Plumbers do this a lot and it is not cool. Regardless of that moving a column without the advice of a structural engineer is a good way to make your house fall down generally even if the column is actually concrete filled steel with no candy like the rest of us have.

If you take those basement lally columns away you could ruin the support of the whole structure. If a contractor finds a joist is severely damaged a sister beam can be installed alongside the normal one for extra strength. Starts below ground with a concrete lally column footing for stability. This pathway can be complex and circuitous where columns rest on top of beams below.

The lally columns should rest on independent footings which are at least 12 inches deep as shown in figure 2.
