WHAT IS THE INSTALLATION PROCESS OF FLOOR JOIST COVERINGS?
Once the joisting works have been completed and signed off by the relevant parties as fit for purpose a working deck is required to continue construction works to the next level.
Should the floor required be at 1st floor level or any level where there is a risk of falling through the floor joists, the drop from height conditions must be set to control such risks. Often this will be achieved by erecting staging below the floor joists or by placing crash matting safety systems to the area of floor below the joisted area to soften the landing in case of a fall.
All access to areas below a joisted zone should be restricted until the sub-floor works have been completed.
Once the risks have been managed the works can commence. It is important to store the sub-floor materials properly by not overloading joists with excessive weights placed in one area as to prevent the risk of overstressing or even failure of the joists. A competent site manager working on larger projects will usually have a material loading plan available for the use of materials to be sited by crane or tele-handler, which has considered all such risk prior to works commencing.
Sub-floors are usually moisture resistant chipboard with tongue and grooved edges, the boards are glued to the top of the floor joists with a PU glue with all edge joints glued. When the glue is still uncured the boards will be fixed with a nail gun into the top of the joists using ring shank nails at approximately 300mm centres.
Dependent upon the type of construction methods of the project there may be a requirement to leave an expansion gap where sub-floorboards meet structural walls or columns etc, this detail would usually be denoted within the structural engineers' drawings and/or specification.
