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 prior art construction of the spike of the system of glueless connection of floor panels [1], which is an element of the mechanical end connection system of two flat panels of a building structure. The spike is made in the form of a pointed elastic tab, oriented perpendicular to the surface of the corresponding end, and is equipped in the area on the bottom of the horizontal surface with a locking protrusion for fastening.

The disadvantages of this analogue are the presence of play along the axis of connection of the panels after their assembly and the large visible opening of the seam between the cohesive panels in excess of 1 mm. The above disadvantages are caused solely by the shape of the stud, which allows the assembly of two panels by moving the panel with the stud only in the assembly plane, in particular in the horizontal plane of positioning the panel with a groove. This circumstance requires the presence of large (> 0.2 mm) tolerances on the mating surfaces in the manufacture of both the stud and the groove reciprocal to it.

The closest in technical essence and the achieved result is the spike design system of glueless panels for the field [2], made on the end of the panel in the form of a profiled elastic tab. The spike is rectangular in shape with a thickness less than twice its width. When forming on the end of the panel, the spike with the extended part of the foot is oriented perpendicular to the surface of this end. The profiling of the tenon is due to the presence on the upper plane of its surface of a recess (intended for the subsequent installation of a separate fixing element), positioned relative to the end practically in the middle of the width of the elastic foot (if we consider the elastic foot of the tenon from the position of its vertical cross section). This device is adopted as a prototype device.

The disadvantage of the prototype is the irreproducible visible opening of the seam between the cohesive panels. This is due to the use of an additional locking element to set the position of the rallying panels relative to each other, which is placed when honing the panels in relatively (i.e. with an error) symmetrically made recesses on the mating surfaces. Therefore, the manufacturing errors of the stud itself, the notches in the groove and the fixing element are randomly superimposed during assembly, which leads to significant and little controlled fluctuations in the dimensions of the visible opening of the seam between the above panels after they are installed in the floor covering (floor).

The task to which the creation of this utility model is aimed is to increase the service life of the assembled glueless panel floor by increasing its level of resistance to negative environmental influences (mainly, increasing moisture resistance) by reducing the visible opening of the interpanel seam.

In the claimed utility model, the expected technical result is to reduce the visible opening of the seam between the mechanically connected panels forming the floor.

The specified technical result is achieved by the fact that in the design of the spike of the system, the adhesiveless connection of the floor panels made at least on the vertical surface of one of the ends of the rectangular rigid panel, which consists of three layers sequentially placed from top to bottom in the vertical plane, including the first protective a layer of at least two films, a carrier layer of medium fibreboard MDF (Medium Density Fibroboard) or high density HDF (High Density Fibroboard), and a reverse layer, and contains at the end, false end with a spike a response groove, apply a carrier layer with a thickness of 6 × 10 ^-3 m to 9 × 10 ^-3 m, and the cross section of the tenon in the vertical plane corresponds to the profile shown in Fig.1.

It is desirable that in the construction of the spike of the system for gluing the floor panels the first film is preferably made on the basis of melamine or acrylic resin and contains abrasive particles, in particular aluminum dioxide particles, and the second film represents a decorative surface.

The utility model is illustrated by drawings. Figure 1 shows the cross section of the tenon in the vertical plane at a scale of 8: 1 with a thickness of the carrier layer of 6 × 10 ^-3 m .; figure 2 schematically shows an intermediate stage of glueless joining of rectangular rigid panels in a section of the floor (shown in vertical sectional view).

1. The bearing layer.

2. The groove.

3. Groove profile.

5. The backing layer.

6. Thorn.

F is the direction of the mechanical force applied during assembly.

At the end of the carrier layer 1 (FIG. 1 and FIG. 2), a rectangular rigid panel is provided, for example, by mechanical milling methods, a spike 2 (FIG. 1 and FIG. 2). The profile of the stud 3 (Fig. 1 and Fig. 2) has a shape, according to which in a vertical section the horizontal surface of the stud (Fig. 1 and Fig. 2) is made essentially with zero curvature and is oriented parallel to the plane of the surface of a rectangular rigid panel, the lower surface is profiled into a protrusion so that the latter is a surface convex to the bottom of the panel with a curvature of 1 / R. The carrier layer 1 (FIG. 1 and FIG. 2) can be made from 6 × 10 ⁻³ m to 9 × 10 ⁻³ m thick from a medium MDF (Medium Density Fibroboard) or high HDF (High Density Fibroboard) fiberboard density. A protective layer 4 is formed on its surface (FIG. 2), consisting of at least two films. Usually this layer is called "laminate". The first film of the protective layer 4 (Figure 2) can be made, preferably, based on melamine or acrylic resin and contains a filler in the form of abrasive particles, for example, particles of aluminum dioxide (Al ₂ O ₃ ). The second film of the protective layer 4 (Figure 2) is placed between the first film of the protective layer 4 (Figure 2) and the actual carrier layer 1 (Figure 1 and Figure 2). It is a decor, i.e. a film decoratively decorated by appropriate coloring and / or embossing, for example, made on the basis of a paper sheet. The reverse layer 5 (FIG. 2) serves in the device to compensate for stresses in the carrier layer 1 (FIG. 1 - FIG. 2) and protect it from moisture from the subfloor (i.e., the floor on which they are laid and closed in prefabricated floor panel). The back layer 5 (Figure 2) is made in the form of unrefined or impregnated with resins, preferably melamine or acrylic resin, paper.

Example 1

In the present example, rectangular rigid panels are used for glueless floor construction with the following dimensions: length - 1290 mm, width - 194 mm, thickness - 7 mm. Each of the panels is equipped with two spike-groove mechanical connection means formed at the ends of its opposite long sides. As the carrier layer 1 (FIG. 1), a 6 mm thick high density fiberboard (HDF) was selected. As the protective layer 4 (FIG. 2), a two-layer laminate of 0.35 × 10 ^-3 m thickness was used, the thickness of the decor layer being 0.15 × 10 ^-3 m and the thickness of the film based on acrylic resin was 0.2 × 10 ^-3 m. The backing layer 5 (FIG. 2) was made of paper impregnated with melamine resin with a thickness of 0.65 × 10 ^-3 m.

The spike 2 (Fig. 1) was milled in the form of an elastic tab on one (first) of the ends (in this case, the end of the long side of the rallied panels) so that the protrusion on the lower surface was a surface convex to the bottom of the panel with a curvature of 1 / R equal to 0.22. Response to the described spike 2 (Fig. 1 and Fig. 2), the groove 6 (Fig. 2) in the form of a recess was formed by milling the second (opposite to the first) end face with the length of the side of the panel under consideration.

The assembly of a floating floor with an area of 10 m ² from the panels of the described design of the spike 2 (Fig. 1) and the groove 6 (Fig. 2) was performed with a shift of the position of the ends of each next stacked floor row by half the length of the panel. Initially, along the selected wall of the room, the first row of rectangular rigid panels was laid with the long side so that the ends of the short side were adjacent to each other, and the groove 6 (Figure 2) was facing away from the wall of the room. Then, each of the panels of the second row was alternately oriented with a spike 2 (Figure 2) to the groove 6 (Figure 2) of the previously laid row, the articulated panel was tilted at an angle of approximately 45 ° to the surface of the subfloor and with a force F (Figure 2) of approximately 9 -10 kg introduced the springy locking tab of the spike 2 (Figure 2) into the groove of the groove 6 (Figure 2), while simultaneously turning the articulated panel into a horizontal position. After laying the second panel of a new floor row, the short ends of the previous row of panels, positioned approximately in the middle of the length of the panel, were pressed with the required number of hits of a rubberized hammer or an end metal mandrel was used, which allowed the use of a metal (i.e. not rubberized) hammer.

After completing the installation of the last row of rectangular floor panels assembled without glue, we examined the visible opening of the joints between the panels using an RF651-5 optical non-contact micrometer. This micrometer provides an error in measuring the opening of the seam with sizes up to 5 mm no more than 10 microns.

The average results of measurements of the visible opening of the seam of the assembled from rectangular panels of the floor with the proposed design of the spike 2 (Figure 1) are presented in Table No. 1.

As follows from Table No. 1, the proposed device ensures the achievement of the claimed technical result in the form of reducing the visible opening of the seam between the floor panels that are mechanically (like a groove-spike) connected panels.

Example No. 2

In this example, rectangular rigid panels were used for glueless floor construction with the following dimensions: length - 1290 mm, width - 194 mm, thickness - 9 mm. Each of the panels was equipped with four spike-groove mechanical connection means, formed opposite at the ends of its sides. As the carrier layer 1 (FIG. 1), a high-density fiberboard (HDF) of 7 mm thickness was selected. As a protective layer 4 (FIG. 2), a three-layer laminate 1.20 × 10 ^-3 m thick was used, moreover, in addition to the top film based on melamine resin 0.50 × 10 ^-3 m thick and the decor layer 0.30 thick lying underneath × 10 ^-3 m, between the carrier layer 1 (Fig. 1 - Fig. 4), an additional film based on melamine resin with a thickness of 0.40 × 10 ^-3 m was built in, reinforcing the resistance of the protective layer 4 (Fig. 2) to external environment on the floor surface.

The reverse layer 5 (Figure 2) was made of unrefined paper with a thickness of 0.80 × 10 ^-3 m

The spike 2 (Fig. 1) at the two ends of the adjacent sides of the panel (in this case, the end of the long side and the adjacent end of the short side of the panel) was milled in the form of an elastic tab so that the protrusion on the lower surface was a surface c convex to the bottom of the panel curvature 1 / R equal to 0.12. Response to the spikes 2 (Fig. 1), the spikes 6 (Fig. 2) in the form of recesses in the carrier layer 1 (Fig. 1) were formed by mechanical milling methods on the opposite ends of this panel.

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 was laid along the selected wall of the room so that the end lock joints of these short sides were latched, and the groove 6 (Figure 2) of the long side of the panel was facing away from the wall of the room. For creaking of the spike 2 (FIG. 2) and the groove 6 (FIG. 2) into the lock connection of the short ends of the first row of the floor, the next of the stacked panels was rejected from the subfloor at the point of contact between the spike 2 (FIG. 2) and the groove 6 (FIG. 2) the short ends of the rallying panels at about 45 ° and with a force F (Figure 2) equal to 9-10 kg introduced the spring retaining tab of the spike 2 (Figure 2) into the recess of the groove 6 (Figure 2), while at the same time leading to a smooth turn the articulated panel to a horizontal position. So they continued to act until a set of the first row of panels against the wall of the room.

The second row of glueless floor panels rallied with the first row at the end length of the side of the panel using a similar technique with the panel tilted at an angle of about 45 ° relative to the subfloor, i.e. each of the panels of the second row was alternately oriented with a spike 2 (Figure 2) to the groove 6 (Figure 2) 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 F (Figure 3) of 10-12 kg introduced the springy locking tab of the spike 2 (Figure 2) into the groove of the groove 6 (Figure 2), while simultaneously unrolling the articulated panel in a horizontal position.

Then, the next panel of the second row was positioned indented from the short end of the previous panel by about 10-15 mm, and after it snapped along the long end, the panel with the short end of the previously mounted panel was articulated with the required number of hits of the rubberized hammer until it snapped into the mechanical connection. Similarly, the installation of the entire floor was carried out. After completing the installation of the last row of assembled from rectangular panels without glue flooring, in which the spike 2 (Fig. 1) of the proposed design was used, the visible opening of the joints between the panels was studied using an optical non-contact micrometer of the RF651-5 grade, providing a measurement error of up to 5 mm for the object under study no more than 10 microns. The averaged results of measurements of the visible opening of the seam of the assembled from rectangular panels of the floor with the proposed profile of the spike 2 (Figure 1) are presented in Table No. 2.

As follows from Table No. 2, the proposed device ensures the achievement of the claimed technical result in the form of a reduction in the visible opening of the seam between the floor-forming mechanically connected panels of the tongue-and-groove type.

Example 3

In the last example, rectangular rigid panels are used for glueless floor construction with the following dimensions: length - 1290 mm, width - 194 mm, thickness - 11 mm. Each of the panels is equipped with two spike-groove mechanical connection means formed at the ends of its opposite long sides. As the carrier layer 1 (FIG. 1), a medium-density fiberboard (MDF) of 9 mm thickness was selected. As the protective layer 4 (FIG. 2), a two-layer laminate with a thickness of 1.4 × 10 ^-3 m was used, the thickness of the decor layer being 0.4 × 10 ^-3 m and the thickness of the film based on acrylic resin was 1.00 × 10 ^-3 m. The reverse layer 5 (Figure 2) was made of unrefined paper with a thickness of 0.60 × 10 ^-3 m.

The spike 2 (Fig. 1) at the first end (in this case, the end of the long side of the rallying panels) was milled in the form of a fixing elastic tab so that the protrusion on the lower surface was a surface convex to the bottom of the panel with a curvature 1 / R of 0, 45. Response to the described spike 2 (Fig. 1), the groove 6 (Fig. 2) in the form of a recess was formed by milling the second (opposite to the first) end face with the length of the side of the panel under consideration.

Assembling a floating floor with an area of 11 m ² from the panels of the described design was performed with a shift in the position of the ends of each subsequent stacked floor row by half the length of the panel. Initially, along the selected wall of the room, the first row of rectangular rigid panels was laid with the long side so that the ends of the short side were adjacent to each other, and the groove 6 (Figure 2) was facing away from the wall of the room. Then each of the panels of the second row was alternately oriented with a spike 2 (Figure 2) to the groove 6 (Figure 2) of the previously laid row, the articulated panel was tilted at an angle of approximately 45 ° to the surface of the subfloor and with a force F (Figure 2) of about 9 -10 kg introduced the springy locking tab of the spike 2 (Figure 2) into the recess of the groove 6 (Figure 2) at the same time as this smooth rotation leading the articulated panel to a horizontal position. After laying the second panel of a new row of floors, the short ends of the previous row of panels, positioned approximately in the middle of the length of the panel, were pressed with the required number of hits of a rubberized hammer or an end metal mandrel was used, which made it possible to use a metal hammer for fitting.

After completing the installation of the last row of rectangular floor panels assembled without glue, we examined the visible opening of the joints between the panels using an RF651-5 optical non-contact micrometer. This micrometer, as mentioned above, provides an error in measuring the opening of the seam between the panels with a size of up to 5 mm no more than 10 microns.

The average results of measurements of the visible opening of the seam of the assembled from rectangular panels of the floor with the proposed design of the spike 2 (Figure 1) are presented in Table No. 3.
