Description

The utility model relates to the field of construction and, in particular, to a floor covering, consisting of interconnected floor panels, as well as to the floor panel itself, made with the possibility of connection with similar panels to form a coating.

The prior art panels for flooring, along the edges of which are made a groove and a tongue of a tongue-and-groove connection, such boards are quite easily installed in place. Known panels can be made of wood, a board pressed from particles, or sheet fiber and are most often coated on the upper surface, for example, with varnish or some kind of laminate. However, when installing such panels for flooring, gaps of different widths may form. In such gaps, dirt, moisture will accumulate, under the influence of which the middle will swell. Such swelling will lead to a rise in the upper surface in the immediate vicinity of the joint and, as a result, wear of the protruding edges of the panel, which in turn leads to a reduction in the service life of the floor covering.

A floor covering is known consisting of solid floor panels (patent No. 2200809 for the invention, IPC E04F 15/02, 2000.01.10) containing a wood-based base material, said solid floor panels are provided on the edges of two opposite sides with connecting parts formed as integral with the specified basic material on a wood basis and interacting with each other. The connection of the panels is ensured by moving them relative to each other mainly by plane movement.

For floor panels made of pressed wood-fiber boards equipped with mechanical fixing means, the quality and strength of mechanical fixing decreases as the carrier layer becomes thinner. In addition, they do not have sufficient moisture resistance.

Panels made of polyvinyl chloride (PVC) have the qualities of a laminate, wooden board and linoleum. A variety of decorative layers allows you to make all kinds of design options. Resistance to moisture, which allows you to easily install PVC panels inside the bathroom, in the kitchen.

The prior art panels that can be made of PVC.

The closest in technical essence to the claimed technical solution selected panel (patent No. 2671364 for the invention, IPC E04F 15/02, 2018.10.30), configured to connect with similar panels to form a coating, including, located in the center of the supporting base having the upper side and the bottom side, and the specified carrier base has a mechanical connection in the form of a groove and a tongue of the tongue joint located on opposite edges of the panel, and the tongue of the tongue joint is located in the opposite direction. parallel to the upper side, and made with a rounded front region and the lower region, the lower region is made as a support region, which is located closer to the level of the upper side of the panel compared to the lowest part of the lower front region, and the groove is made in the form of a recess for inserting the protrusion tongue-and-groove connection of the next panel with the provision of adhesion of adjacent panels at the junction of the ribs, while this recess is formed by an upper protrusion and a lower protrusion, and the specified lower protrusion has a protrusion th up edge for supporting the lateral support region of the tongue.

According to the analogue, when laying the second and subsequent panels, the movement of the panels in the longitudinal direction is fixed by the connection along the long and short sides of the panel, and the movement of the panel in the perpendicular direction only by the connection along the long side of the panel. To this end, the panel includes, at the junction of the first pair of opposite ribs, the first set of complementary connecting profiles and at the junction of the second pair of opposite ribs, a second set of complementary connecting profiles is different from the others, which complicates the installation of the panels forming the flooring and, as a result, reduces the reliability of the joints.

This embodiment of the panels allows you to connect the panels to form a floor covering of only a rectangular shape and does not allow you to connect the panels of a different shape, for example, hexagonal.

To ensure a reliable and durable connection of all the ribs and a relatively simple installation of the panels, it is proposed to improve the connection profiles, which will allow tongue-and-groove connection on the short side of the panel after moving the panels along the long side, and the panels are prevented from moving in the perpendicular direction by connecting along the long and short sides of the panels.

A disadvantage of the known devices is the low operational reliability due to the fact that the blocking of flooring elements is provided only in the horizontal plane. The proposed technical solution provides locking elements in the vertical plane, i.e. in a conventional laminate, blocking takes place only on two sides and is usually issued only in rectangular or square shape. In the proposed technical solution on all four sides, the lock provides reliable fastening and the panels do not "play" either horizontally or vertically, respectively, less load on the lock. In addition, this design of panels allows you to produce and connect panels not only rectangular and square elements, but also polygonal - rhombuses, hexagons, etc. in this case, the lock will also be carried out on all sides of the panel.

In addition, the reliability of the connection of the panels is influenced by the presence of microroughnesses of the substrate and the sliding effect between the floor covering and the substrate. The substrate is located between the main floor of the room and the floor panel and in places with insufficient thickness of the substrate, the floor panel is suspended in the air above the defective floor area. In this place, under certain loads, destruction of the lock section connecting the panels can occur.

The objective of the utility model is to create a reliable and easy-to-use floor covering consisting of interconnected floor panels.

The technical result consists in increasing the operational reliability of the device, by reducing the load on the lock and, accordingly, the visible opening of the interpanel seam, which is caused by the presence of microroughnesses in the substrate and the sliding effect between the floor covering and the substrate.

The specified technical result is achieved due to the fact that the proposed panel made with the possibility of connection with similar panels to form a coating, including, located in the center of the supporting base having the upper side and the lower side, and the specified supporting base has mechanical connection in the form of a groove and the tongue of the tongue and groove joint located on opposite edges of the panel, the tongue of the tongue and groove joint located in a direction parallel to the upper side is made with angled front region and lower region, and the lower rear region of the specified tongue of the tongue-and-groove connection, made as a supporting region, is located closer to the level of the upper side of the panel compared to the lowest part of the lower front region, and the groove is made in the form of a recess for inserting the protrusion of the tongue and groove connection of the following panels providing adhesion of adjacent panels at the junction of the ribs, wherein said recess is formed by an upper protrusion and a lower protrusion, and said lower protrusion has a protruding up edge to support the support area of the tongue of the tongue and groove joint.

What is new is that part of the end surface of the panel under the tongue of the tongue-and-groove connection is made at an angle and adapted for contact in assembled condition with part of the inclined end surface under the groove of another panel to form a gap, ensuring that the panels are locked in both horizontal and vertical planes, this bottom side of the base of the panel is made with corrugation.

Due to the fact that in the proposed panel, a part of the end surface of the panel under the tongue of the tongue-and-groove connection is made obliquely and adapted for contact in assembled condition with a part of the inclined end surface under the groove of the other panel to form a gap, ensuring that the panels are locked in both horizontal and vertical planes, the floor covering formed from such panels has high strength and resistance to loads, which increases the operational reliability of the floor covering.

The presence of a gap and corrugations on the lower side makes it possible to compensate for the formation of air cavities in the case of a loose fit of the panel to the substrate. By eliminating the influence of the presence of roughness of the substrate and the sliding effect between the flooring and the substrate, the service life of the flooring is increased, since there is no need for frequent repairs, which increases the operational reliability of the flooring.

In addition, this design of panels allows you to produce and connect panels not only rectangular and square elements, but also polygonal - rhombuses, hexagons, etc., providing reliable fastening on all sides of the panel and the panel does not "play" neither horizontally nor vertical, respectively, the load on the lock is reduced.
