FLOORING STRIPS AND METHOD OF FLOORING STRIP PRODUCTION AND MOUNTING Russian patent published in 2006 - IPC E04F15/04 

FIELD: building, particularly fixing systems to connect flooring strips one to another and flooring strips.

SUBSTANCE: flooring strip comprises groove undercut in one long side of flooring strip and extension made on opposite long flooring strip side. The groove has inner fixing surface facing upwards and spaced from edge thereof. Extension and groove may be connected with each other or disconnected from each other by rotating the flooring strips about center line located near plane of strip surface and common intersection plane of two adjacent flowing strips. The groove in undercut with the use of at least two disc cutting tools having axles of disc rotation inclined one to another so that inner part of inner groove section is formed and then fixing surface is created. The fixing surface is located near groove opening. Method of floor assemblage of above flooring strips involves laying next flooring strip near previous one; inserting extension of previous flooring strip in orifice of next flooring strip groove; inclining next flooring strip upwards during extension insertion in the groove; simultaneously inclining next strip downwards in final position. Groove undercutting method involves mechanically treating flooring strips with the use of at least two different rotary cutting tools. Tool for flooring strips installation is made as wedge with contact surface facing upwards created on widened end thereof.

EFFECT: reduced labor inputs for flooring strips laying.
