Laying the finished parquet on the floor joists

Laying the finished parquet elements on the floor joists is generally possible on raw concrete ceilings. Thick parquet elements are used here 22 mm, glued together with a tongue and a tongue, which are nailed to the joists.
The axis distances of the floor joists should be selected in this way, not to exceed the maximum support spacing, given by the manufacturer of the parquet.
The floor joists are laid without touching the walls, “floating”, on the edge strips of the insulating material. Means, that there is no fixing to the bare ceiling.
For better sound and heat insulation, the free space between the joists can be filled with insulation boards. The distance between the layer of insulating material and the parquet should be approx. 10-15 mm.
When laying on floor joists, pay particular attention to the height provided, adjacent floors. As a rule, the floor joist substrate will also be made there, its height should then be carefully adjusted taking into account the thickness of the intended floor covering, up to the already laid parquet floor.
Nailing the finished parquet elements can be done diagonally through the groove or diagonally through the bottom lip of the groove.
To prevent damage to the wood, it is recommended for the DIY enthusiast to nail it through the groove.

The first row is laid out “planks ”and nails it to the floor joists and sticks the butt joints together. Please observe the minimum requirements 15 mm distance from the wall (for very large surfaces 2 mm per running meter).
The resulting expansion joint is secured with wooden wedges. The required length of the last is carefully measured “boards” first row, taking into account the distance to the wall. The dimension is transferred with the ruler and the angle bar to the provided one “board”.
A stationary circular saw can be used to cut the boards to length, as well as a hand-held circular saw, I saw a fox or a carpentry saw. If it works out “boards” according to the lengths available (the remainder in a row is used to start the next row), the cut point is always at the edge of the surface.
Subsequent covering with a skirting board, slight cutting inaccuracies.
Before embedding each new one “boards” glue is applied to the joint forehead and the longitudinal side “boards”.
Depending on the method of nailing, the glue is applied to the projection or the projection. If boards are nailed by the tabs, it is better to use a glue bottle for applying glue.
“The board "sits as tightly as possible on its front side, and then closes the longitudinal slot to the previous row.
Be very careful when striking with a hammer, so as not to separate those already arranged “boards”. When the butt joint of two adjacent “boards” is not tightly closed, so-called. “iron drawing die”.
To avoid damaging the wood, it is used for joining “boards” piece of square timber, resp. leftover “boards” as a wood for tapping.
If the above-mentioned. other tools can be used, suitable, which can be used as a lever.
When using an iron drawing die, it is absolutely necessary to pay attention to this, that the opposite expansion joint is not narrowed.
Nailing “boards” takes place obliquely through the tongue or through the lower lip of the tongue. The nails are driven so deeply, so that they can be embedded without difficulty connecting “boards”.
