Recommendations for preparation of the base for installation of parquet plank:

A parquet plank is installed on the pre-arranged base in form of skeleton from beams and joists which are most often spaced at established intervals. Beams have a large cross-section; they are spaced far apart and rest on external and internal walls. Joists have a smaller cross-section and can be both self-supporting (i.e. rest only on joints to walls or partitions) or installed on the existing base (across beams or on floor slabs).

From different sources one may find information that for domestic premises a design floor load is 200 kg/m2, for common facilities 400 kg/m2. The main problem in selection of cross-section and material of self-supporting joists and pitch setting is a lack of information on operation load and a narrow choice of plank size (mostly 50*150mm and 50*200mm).

The option of joist installation on existing base is quite obvious. Here the main thing is a reliable fixation of joists (plywood) to the bearing construction, using a sound insulation material between joists and base, and the right choice of the size of jack point screw to attach parquet plank to plywood. As a rule, a cross-section of joists mounted on rigid base is not calculated but selected proceeding from a finished floor elevation. In case of mounting parquet plank on plywood it is essential to consider its thickness. Commonly, birch plywood 15 or 20mm thick is used. For mounting on 15mm plywood (economical option) jack point screws 35mm long are used, and on 20mm plywood (professional reliable option) – 45mm long.

Therefore, in construction of plank floor slabs it must be taken into account:

  • prevention of static deformation (so called “operating deflection”);

  • sound insulation of slab (solved by selection of efficient materials absorbing unintended vibration);

  • adequate attachment of floor pavement (the right selection of type and size of jack point screws).

On long-standing experience of construction and finishing works it may be recommended for slab manufacturing to use dry planed wood with a minimum number of snags. An ideal however more expensive option would be a slab from dry glued laminated lumber or LVL.  

For sound insulation of slab, a distance between joists is selected in such a way as to tightly place the anti-vibration material between joists with a slight deformation. 

We suggest using the following formula for determination of plank thickness:

a minimum thickness of parquet plank (mm)  =  joist spacing (mm)/K, where

K = coefficient for conversion of the thickness of parquet plank into base spacing (K = 20 for terrace flooring, K = 15 for domestic timber floor).

In our opinion, this formula is general-purpose and can be extended with due allowance for “squeaking” to cover the timber floor as well, which is placed indoors. We obtain:

Доска пола толщиной 20мм - это паркетная доска и в большинстве случаев монтируется на фанерное основание толщиной 15мм (эконом вариант) или 20мм (профессиональный вариант). 

Consumption of jack point screws

In primary calculation of jack point screw consumption for attachment of parquet plank it is essential to consider the following parameters:

  • thickness and width of plank;

  • distance between joists;

  • size of jack point screws for “hardwood” and “softwood”
