摘要
The invention relates to the field of construction and, in particular, can be used in floating flooring system, which welds by mechanical lock tongue and groove type. Structurally tenon system glueless connection for floor panels is performed, at least on the vertical surface of one of the ends of rigid rectangular panel. Said rigid rectangular panel composed of three layers, successively arranged from the top down in a vertical plane. The first layer is a protective layer of at least two films, the second (carrier) layer is formed from fiberboard average MDF (Medium Density Fibroboard) or high HDF (High Density Fibroboard) density, and the third layer serves as a working layer . The panel includes at the end opposite to the end with a spike, back slot. The design uses a carrier layer thickness ranging from 6 × 10 -3 m to 9 × 10 -3 m, and the cross-section in a vertical plane cleat corresponds to the profile shown in Figure 1. In the apparatus the first film is made is preferably based on melamine or acrylic resin, and includes abrasive particles, in particular particles of aluminum dioxide, and the second film is a decorative surface. The expected technical effect is to reduce the visible joint opening between forming the floor panels mechanically joined. 1 bp 1 and ZP f-ly, 3 Tab. 2 yl.
