Description

The utility model relates to the field of construction and, in particular, can be used in a system of floating floor coverings, rallied by means of a mechanical lock type groove-spike.

The technical solution [1] is known from the prior art, in which the surface structure of the elements of a mechanical lock of a system for glueless joining of floor panels is disclosed. The connection of the floor covering from rigid rectangular panels provides a mechanical slot-type end lock. In this case, the spike is made in the form of an elastic tab with the end side gently sloping along the radius. On the lower side of the elastic tab there is an isosceles angular locking protrusion, and the groove is provided with such a radial recess that when the panels are connected, a visible opening of the seam between the connected rigid panels is formed.

The disadvantage of this analogue is that a significant part of the surface of the elements of the considered mechanical lock is in contact with the atmosphere and therefore (due to fluctuations in atmospheric humidity) the analogue design has low moisture resistance.

Closest to the proposed device in terms of technical nature and the achieved result [2] is a device in which the surface structure of a mechanical lock of a system of adhesiveless joint of floor panels is disclosed. The mechanical lock is made in the form of a groove and a spike mating to it, placed on opposite sides of the flooring elements. The surface of the constituent elements of the specified mechanical lock almost completely forms the material of the carrier layer. When the groove and the spike reciprocal are joined, the elements of the flooring are connected with the formation of a visible opening of the seam between them. This analogue is adopted as a prototype.

The disadvantage of the prototype is the relatively low moisture resistance.

The task to be solved by the claimed utility model is to provide the possibility of wet cleaning the floor, assembled without the use of glue from rectangular laminated panels.

The technical result expected from the claimed utility model is to increase the moisture resistance of the flooring.

The claimed technical result is achieved by the fact that in the surface structure of the mechanical lock of the system, the adhesiveless connection of the floor panels formed from the first and second rectangular rigid panels, each of which is made of at least three layers, sequentially bonded to each other from top to bottom in a vertical plane including a protective layer, a carrier layer and a reverse layer, the first of the rectangular rigid panels provided at the end with means of mechanical connection such as a groove, and the second of rectangular rigid panels contains at the end adjacent to the end of the first rigid rectangular panel, the response means of a mechanical connection such as a tenon, the groove surface and the tenon surface are hydrophobized to a depth of 3 × 10 ^-5 m to 6 × 10 ^-4 m.

It is desirable that in the surface structure of the mechanical lock of the system, the glueless connection of the floor panels, the hydrophobized zone is formed in the carrier layer by impregnation.

It is advisable that wax and / or wax-like polymer be used in the surface structure of the mechanical lock of the system without adhesive joint of the floor panels for impregnation.

The claimed utility model is illustrated by drawings. Figure 1 schematically shows a section of a rectangular rigid panel in a vertical plane across the groove and spike to the impregnation (hydrophobization) of their surfaces; figure 2 schematically shows a section of a rectangular rigid panel in a vertical plane across the groove and spike after impregnation (hydrophobization) of their surfaces; figure 3 schematically shows a view of two connected rectangular rigid panels for the floor during installation of the third mentioned panels (given in cross section in a vertical plane across the tenon and groove).

The list of positions:

1. The bearing layer.

11. The carrier layer of the first rectangular rigid panel.

12. The carrier layer of the second rectangular rigid panel.

13. The carrier layer of the third rectangular rigid panel.

2. The protective layer.

3. The backing layer.

4. Thorn.

5. The groove.

6. Water-repellent tenon surface.

7. Hydrophobized groove surface.

8. The direction of application of mechanical force during installation.

The surface structure of the mechanical lock is a profiled end surface, made mainly in the carrier layer 1 (Figure 1-Figure 3), on the upper (working) surface of which the protective layer 2 is fixed (Figure 1-Figure 3). From the side of the subfloor (or opposite to the placement of the protective layer 2 (FIG. 1 to FIG. 3), the surface of the carrier layer 1 (FIG. 1 to FIG. 3)) are fastened to the surface of the carrier layer 1 (FIG. 1 to FIG. 3) reverse layer 3 (Figure 1-Figure 3). When the protective layer 2 (Fig.1-Fig.3) is made in the form of a two-layer laminate, the latter is a decor layer coated with a high-strength film (overlay), preferably based on melamine or acrylic resin. In the case of performing the protective layer 2 (Fig. 1-Fig. 3) in the form of a composite laminate (i.e., a coating consisting of more than two films), it is a base layer based on melamine or acrylic resin on the surface of which a layer is thermally fixed decor, which in turn is also covered with a high-strength film (overlay), preferably also based on melamine or acrylic resin. Mentioned overlay can be impregnated with abrasive particles, which significantly increase the wear resistance of the working surface of the flooring. As the carrier layer 1 (Figure 1-Figure 3) is usually used wood-fiber board of medium (Medium Density Fibroboard) or high (High Density Fibroboard) density. To the reverse side (the side opposite the working surface of the plate) of the carrier layer 1 (FIG. 1 to FIG. 3), the reverse layer 3 (FIG. 1 to FIG. 3) is firmly attached. Unrefined or impregnated with resin (preferably melamine or acrylic resin) paper is used as the backing layer material. Functionally, the reverse layer 3 (FIG. 1 to FIG. 3) is intended to compensate for mechanical stresses in the carrier layer 1 (FIG. 1 to FIG. 3) due to the presence of a protective layer 2 on its surface (FIG. 1 to FIG. 3) having other than the carrier layer 1 (Figure 1-Figure 3) mechanical characteristics. In addition, the above-mentioned layer 3 (FIG. 1-FIG. 3) reduces or completely suppresses the entry of moisture into the plate of the carrier layer 1 (FIG. 1-FIG. 3) from the subfloor.

The glueless connection of the panels is ensured due to the fact that on their vertical (end) surfaces by means of instrumental milling they form means of mechanical connection such as a spike-groove. In this case, the spike 4 (Fig. 1-Fig. 3) is made in the form of a spring-loaded locking tab, the surface of which is in contact with the surface of the groove 5 (Fig. 1-Fig. 3). For a substantial increase in the moisture resistance of a mechanical lock (and, accordingly, a substantial increase in the moisture resistance of a flooring joined from panels), the surface of the spike 4 (FIG. 1 to FIG. 3) and the surface of the groove 5 (FIG. 1 to FIG. 3) are subjected to hydrophobization. This operation is carried out by impregnation due to the placement of the ends of the panels with a spike 4 (FIG. 1 to FIG. 3) and a groove (FIG. 1 to FIG. 3) in the zone of jet-drop spraying from the nozzle at a temperature of about 92 ° C to 95 ° C wax or wax-like polymer. Thus, hydrophobized surfaces of the spike 7 (FIG. 2 and FIG. 3) and a groove 7 (FIG. 2 and FIG. 3) are formed in which the thickness of the impregnation layer reaches a value of 3 × 10 ⁻⁵ m to 6 × 10 ⁻⁴ m.

Rectangular rigid panels are used for glueless floor construction with the following dimensions: length - 1290 mm, width - 194 mm, thickness - 8.6 mm. Each of the panels is equipped with two spike-groove mechanical connection means formed at the ends of its opposite long sides. The surface of the spike 4 (FIG. 1) and the surface of the groove 5 (FIG. 1) are subjected to hydrophobization so that the hydrophobized surface of the spike 6 (FIG. 2) has an impregnation layer 3 × 10 ^-5 m thick and the hydrophobized surface of the groove 7 (FIG. 2) has an impregnation layer with a thickness of 3 × 10 ^-5 m

To assemble the flooring, use panels with a protective layer 2 (Fig. 3) in the form of a two-layer laminate 0.10 × 10 ^-3 m thick, in which the thickness of the decor layer is 0.05 × 10 ^-3 m, and the film thickness is based on melamine resin is equal to 0.05 × 10 ^-3 m. As the carrier layer 1 (Figure 3) was selected medium-density fiberboard (MDF) with a thickness of 8 mm The reverse layer 3 (Figure 3) was made of unrefined paper with a thickness of 0.50 × 10 ^-3 m

Assembling a floating floor with an area of 12 m ² from the panels of the described construction was performed with a shift in the position of the ends of each next stacked row by half the length of the panel. Initially, the first row of rectangular rigid panels was laid along the selected wall of the room so that the ends of the carrier layer of the short side of the first rectangular rigid panel 11 (Figure 3) were adjacent to each other, and the groove 5 (Figure 1) was facing away from the wall of the room. Then, each of the panels of the second row was alternately oriented by the carrier layer 12 (Fig. 3) with a spike 4 (Fig. 1) to the groove 5 (Fig. 1) of the previously laid row, the panel was inclined approximately under the corner 45 to the surface of the subfloor and with a force F 9-10 kg 8 (Figure 3) was introduced spring retaining tab of the spike 4 (Figure 1) into the groove of the groove 5 (Figure 3) while bringing the articulated panel into a horizontal position. After laying the second panel of a new row of floors, the short ends of the previous row, positioned approximately in the middle of the length of this panel, were pressed with the required number of hits of a rubberized hammer or an end metal mandrel was used. Similarly, a panel was laid with a bearing layer of a third rectangular rigid panel 13 (Figure 3).

Having completed the laying of the last row without glue assembled from rectangular floor panels, a square edging with side dimensions of 1 m was formed from plasticine in its center. The height of the edging collar was 20 mm. The indicated edged square was filled with water so that the thickness of the water layer on the floor surface was 2 mm. They left everything for 72 hours. After the specified time, water was removed and the plasticine edging was removed from the floor surface. Then, using a portable Surftest SJ-201 profilometer (Japan) (with an error of 5%), the swelling of the floor in the joint zone between the panels was measured on the edging positioning area.

Averaged over 95 measurements, the results of revealing the magnitude of floor swelling due to the effect of water in the weld zone between the panels are given in Table No. 1.

Each of the panels is equipped with two spike-groove mechanical connection means formed at the ends of its opposite long sides. The surface of the spike 4 (FIG. 1) and the surface of the groove 5 (FIG. 1) are subjected to hydrophobization so that the hydrophobized surface of the spike 6 (FIG. 2) has an impregnation layer 4 × 10 ^-4 m thick and the hydrophobized surface of the groove 7 (FIG. 2) has an impregnation layer 4 × 10 ^-4 m thick.

As the carrier layer 1 (Figure 3), a high-density fiberboard (HDF) of 7 mm thickness was chosen. The reverse layer 3 (Figure 3) was made of unrefined paper with a thickness of 0.30 × 10 ^-3 m. Assembling a floating floor area of 12 m from the panels of the described construction was performed with a shift in the position of the ends of each next stacked row by half the length of the panel. Initially, a first row of rectangular rigid panels was laid along the selected wall of the room so that the ends of the carrier layer of the short side of the first rectangular rigid panel 11 (Figure 3) were adjacent to each other, and the groove 5 (Figure 1) was facing away from the wall of the room. Then, each of the panels of the second row was alternately oriented by the carrier layer 12 (Figure 3) with a spike 4 (Figure 1) to the groove 5 (Figure 1) of the previously laid row, the panel was tilted at an angle of approximately 45 ° to the surface of the subfloor and with effort F 9-10 kg 8 (Figure 3) was introduced spring retaining tab of the spike 4 (Figure 1) into the groove of the groove 5 (Figure 3) while bringing the articulated panel into a horizontal position.

Each of the panels is equipped with four spike-groove mechanical connection means formed opposite on the ends of opposite sides. The surface of the spike 4 (FIG. 1) and the surface of the groove 5 (FIG. 1) are subjected to hydrophobization so that the hydrophobized surface of the spike 6 (FIG. 2) has an impregnation layer 6 × 10 ^-4 m thick and the hydrophobized surface of the groove 7 (FIG. 2) has an impregnation layer 6 × 10 ^-4 m thick.

Assembling a floating floor with an area of 12 m ² from the panels of the described construction was carried out as follows. Initially, the first row of rectangular rigid panels with the supporting layer 11 (Fig. 3) was laid along the selected wall of the room so that the ends of the short side were adjacent to each other until they clicked, and the groove 5 (Fig. 1) was turned away from the wall of the room. To close the spike 4 (Fig. 1) and the groove 5 (Fig. 1) of the short ends, the next panel to be laid was deflected from the black floor at the contact point of the short ends of the rallying panels by about 45 ° and a spring-loaded locking tab of the spike was inserted with a force of 9-10 kg 4 (FIG. 2) into the recess of the groove 5 (FIG. 3), at the same time bringing the articulated panel into a horizontal position. So they continued to act until the first row of panels was set against the wall of the room by mechanical locking of the spike and groove of the short ends.

The second row of panels with a carrier layer 12 (FIG. 3) of the adhesiveless floor was rallied with the first row at the end length of the side of the panel using the above technique with an inclination of about 45 relative to the black floor, i.e. each of the panels of the second row was alternately oriented with a spike 4 (Figure 1) to the groove 5 (Figure 1) of the previously laid row, the panel was tilted at an angle of approximately 45 to the surface of the subfloor and with a force of F 9-10 kg 8 (Figure 3) introduced the springy locking tab of the spike 4 (Figure 2) into the recess of the groove 5 (Figure 3), while simultaneously unrolling the articulated panel in a horizontal position. The next panel of the second row was positioned approximately 10-15 mm indented from the short end; after it clicked on the long end, the panel was pressed to the short end of the previously mounted panel with the required number of hits of the rubberized hammer until the mechanical connection of this short end was latched. So the installation of the third row with the supporting layer 13 (Fig. 3) and all subsequent layers was carried out until the floor area was set to 12 m ² .
