Installation of a wooden column in a spacer, between floors. How did I do this alone?

How to put a wooden column, between a concrete slab of the foundation, and a wooden floor, so much so that it stands tightly and does not loosen over time?

❗ This is the next task at my construction site. And once again, everything must be done alone.

I already wrote an article about why I decided to put a column under the roof of the attic floor (if interesting, read here). Today there will be nuances of editing.

The main task.

✅ The main thing that had to be done was to place the column in a spacer so that it stood very tightly, taking into account shrinkage and shrinkage of the column itself and the wooden floor.

Of course, I cannot raise the floor, put up the column, and lower the floor into place. Therefore, it was necessary to resort to tricks:

We divide everything into elements.

1. The column itself. This is a 150 x 150 bar. Having measured the distance from the foundation slab to the wooden floor, I sawed off a beam, but of a smaller length. And less by the thickness of the second element.

2. A piece of board 50 mm. It is needed to better support the ceiling on the column. But its main benefit is that with its help, the column can be put in place.

Without a sledgehammer, nowhere ...

And here is the installation itself:

I did everything from the woods. The installation site was roughly marked.

I did it with a tape measure. When measuring the length of the column, I noticed a simple and obvious thing that a tape measure can be used as a plumb line (not ideal, of course).

• He put the column in place vertically, but with a slight slope, and leaning against the scaffolding. I put a piece of waterproofing underneath.
• And in the resulting space, between the column and the ceiling, he inserted the same piece of board.

It turns out that he plays the role of a "wedge". But since it is not sharpened, everything had to be driven in parallel.

✅ Striking this insert, I simultaneously hammered it in and aligned the column itself. And since this wedge was about 5 mm thicker than the gap, then parallel and the overlap was compressed.

Everything was going pretty tight, but not too much. The main thing is that the "bump" in the middle of the overlap does not work ...

When the column was approximately aligned vertically, and stood in the right place under the overlap, it was necessary to work on the bottom.

Here everything was done with the same sledgehammer, and with the help of a level.

In the final, it remained to fix the bottom and top.

And there is no need for "super-fasteners". The main thing is that the column does not move, which is already very problematic.

As a result, the reinforcement for my overlap is ready.
