Description

Technical field

The solution relates to constructional building element, which can be used especially as a base, damping and insulating material in the laying of flooring systems. Its use is universal and the application is designed for floating floors, parquet, laminate, vinyl, floors using linoleum or PVC materials. , cast, multifunctional, industrial, eventually for walls.

BACKGROUND OF THE INVENTION

At present, a wooden grate is used as the basic building / construction element for all of the above floor systems. This wooden grate has several functions within the traditional flooring system - it is both the basic structural element and the underlying material, partially absorbs / absorbs impacts, thereby cushioning the surface and solidifying the entire floor. It is a timber structure, laid in a linear / parallel or perpendicular “cross” manner, to which OSB / particle board and top floor layer (s) will be attached depending on the selected floor system. This is used especially in the production of floors in indoor sports halls, factories, schools, exhibition areas and the like. It is the most common and the most widespread method of construction and production of floor surfaces in the world.

This classic method has a number of disadvantages, which are based on the nature of the selected substrate - wood, especially the following disadvantages and weaknesses: the entire floor system with timber construction is usually 100-150 mm high, the vast majority of height is just the wooden base grate this creates unwanted pockets, which must then be filled / stuffed and sealed with mineral wool or other thermal or acoustic insulation, or ventilation is installed under the floor (wooden grate ventilation) = expensive installation and operation costs! In the case of use on a sports field, eg for volleyball, basketball and the like, isolation is necessary - to eliminate unwanted noise effects (ball blows and player impacts), echoes ... lowering the ceiling) - decreases the usability of the space and / or increases the height of the building (eg in a 20-storey house the difference in height of 80 mm / floor will mean • »* * total difference in height of the building 1.60 ml) volatility - swelling, expansion and grain + shape in connection with varying humidity, the associated "sound effects" in the form of creaking, very often the need to ventilate the system, wood itself is not a flexible material.

Biodegradable processes (rot, mold, fungi) - high susceptibility to moisture, this poses a major transport problem (water condensation, rain, steaming ... etc ..), wood pests - susceptibility especially during transport (phytopathological and veterinary restrictions / restrictions) / woodworm / woodworm / microbes etc., another big disadvantage is the flammability - high susceptibility to fire, all of which leads to the necessity of prevention in the form of chemical treatment - paint (s) as impregnation, protection against pests + microorganisms treatment (emulsions, mordants, varnishes, varnishes, etc.).

Wood alone does not produce the desired "damping" effect, but is achieved by a structural design (grate composition) or by combining wood with other materials (damping pads, etc.), which is associated with high consumption of valuable natural resources. wood that can be used for these purposes, in addition, the lifetime of the wood is limiting for the overall lifetime of the floor.

EPDM - ethylene-propylene-diene monomer

NR - Natural Rubber

SBR - natural styrene-butadiene rubber / rubber

TPE - thermoplastic elastomers

TPV - thermoplastic vulcanizates

PP - polypropylene

PE - polyethylene

PVC - polyvinyl chloride

Note 1 .: EPDM is sometimes referred to as Ethylene Propylene Dien terpolyMer instead of Monomer or also unconjugated (Monomer)

Note 2 .: Rubber = taken from English - means rubber or rubber

Note 3 .: In rubber / rubber mixtures, the concentration / content of the individual ingredients is indicated by the abbreviation "dsk" = parts per hundred parts of rubber or phr (from parts per hundred rubber). The base of the rubber compound is always 100 parts of rubber (one or more types together). If the rubber used is set with oil or soot, its dosage must be increased so that even 100 parts of rubber are present in such a mixture. The use of 100 parts of rubber as the base of the composition facilitates the dosing of the non-rubber additives, since expressing their concentration with the same dsk value ensures the same rubber / additive ratio for different rubber mixtures.
