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 is known to the groove of the system of glueless connection of floor panels [1], which is an element of the system of mechanical connection with the ends of two flat panels of a building structure. The groove is rectangular in shape, oriented perpendicular to the surface of the corresponding end, and is provided with a recess for fastening on the horizontal bottom surface, which is positioned near the end.

The disadvantages of this analogue are the presence of play along the axis of the connection of the panels after their assembly and the large visible opening of the seam between the cohesive panels in excess of 1 mm. These disadvantages are caused solely by the shape of the groove allowing the assembly of two panels by moving the second abutting panel only in the assembly plane, in particular in the horizontal plane.

The closest in technical essence and the achieved result is the design of the groove system glueless panels for the field [2], made essentially at the end of the panel in the form of a recess. The groove is rectangular in shape, oriented perpendicular to the surface of the corresponding end, and is provided on the horizontal surface of the arch. recesses recess positioned relative to the end almost in the middle of the specified arch. 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 for setting the position of the rallying panels relative to each other an additional locking element, placed when rallying the panels in symmetrically made recesses on the mating surfaces. Therefore, the manufacturing errors of the groove itself, the notches in the groove and the fixing element are superimposed, which leads to significant and little controlled fluctuations in the dimensions of the visible opening of the seam between the above panels after their installation in the floor covering (floor).

The task to which the creation of this utility model is directed is to increase the service life of the assembled glueless panel floor by increasing its level of resistance to environmental influences (mainly 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 claimed technical result is achieved by the fact that in the design of the groove of the system there is an 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 containing at the end, olozhnom end with a slot response spike is applied a carrier layer thickness ranging from 6 × 10 ^-3 m to 9 × 10 ^-3 m, and the cross section of the groove in the vertical plane corresponds to the profile shown in Figure 1.

It is desirable that in the groove design the adhesiveless joint of the floor panels, the first film is preferably made from melamine or acrylic resin and contains abrasive particles, in particular aluminum dioxide particles, and the second film represents a decorative surface.

The claimed utility model is illustrated by drawings. Figure 1 shows the cross section of the groove in the vertical plane at a scale of 10: 1 with a thickness of the bearing layer of 8.4 × 10 ^-3 m .; figure 2 presents the conditional cross-section of the first (a) and second (b) rectangular rigid panels prior to their joining according to the groove-thorn mechanism with visual highlighting of the groove profile by thickening its line; figure 3 presents the intermediate step of docking rectangular rigid panels, depicted in cross section vertically; figure 4 presents the result of a mechanical connection between the ends of two rectangular rigid panels (in the form of a section in a vertical plane).

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

In the carrier layer 1 (Figure 1-Figure 4), a rectangular rigid panel is performed, for example, by mechanical milling methods, a groove 2 (Figure 1 and Figure 3). The profile of the groove 3 (Fig. 1, Phys. 2 and Fig. 4) has an outline according to which, in a vertical section, the surface of the upper jaw is made with essentially zero curvature and is oriented parallel to the plane of the surface of the rectangular rigid panel, the surface of the lower jaw is profiled so which is a surface with a 1 / R curvature in the range of 0.12 to 0.45, and the surface of the arch connecting the lower and upper jaws of the fixing recess is oriented essentially in a vertical plane. The carrier layer 1 (Figure 1-Figure 4) can be made of a thickness of 6 × 10 ⁻³ m to 9 × 10 ⁻³ m from a medium-fibreboard MDF (Medium Density Fibroboard) or high HDF (High Density Fibroboard) density. A protective layer 4 (FIG. 2-FIG. 4) of at least two films is formed on its surface. Usually this layer is called "laminate". The first film of the protective layer 4 (Figure 2-Figure 4) 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 is placed between the first film of the protective layer 4 (FIG. 2-FIG. 4) and the carrier layer 1 (FIG. 1-FIG. 4) and is a decor, i.e. film decoratively decorated with appropriate coloring and / or embossing, for example, on a paper basis. The back layer 5 (FIG. 2-FIG. 4) serves to compensate for stresses in the carrier layer 1 (FIG. 1 to FIG. 4) and protect it from the subfloor (the floor on which they are laid and closed in the prefabricated floor of the panel). The back layer 5 (Figure 2-Figure 4) 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 - 9 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 8.4 mm thickness was selected. As the protective layer 4 (Figure 2, 3 and 4) used a two-layer laminate thickness of 0,50 × 10 ^-3 m, wherein the thickness of the decoration layer had a value of 0,25 × 10 ^-3 m, and the film thickness at the basis of melamine resin was 0.25 × 10 ^-3 m. The backing layer 5 (FIG. 2-FIG. 4) was made of unrefined paper with a thickness of 0.50 × 10 ^-3 m.

A groove 2 (Fig. 1) on one (first) of the ends (in this case, the end of the long side of the rallying panels) was milled in the form of a fixing spike 6 (Fig. 2-b) of the recess so that the surface of the lower jaw was made with a curvature of 1 / R is 0.12. Response to the described groove 2 (Fig. 1), the spike 6 (Fig. 2-b) in the form of a spring-loaded fixing tab 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 2 (Figure 3) was facing away from the wall of the room. Then, each of the panels of the second row was alternately oriented with a spike 6 (Figure 2-b) to the groove 2 (Figure 3) 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 3) equal to 9-10 kg introduced the springy locking tab of the spike 6 (Fig.2-b) in the groove of the groove 2 (Fig.3), while simultaneously turning 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 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 (non-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 averaged results of measurements of the visible opening of the seam of the assembled from rectangular floor panels with the proposed design of the groove 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 - 10 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 9 mm thick high density fiberboard (HDF) was selected. As a protective layer 4 (FIG. 2, FIG. 3 and FIG. 4), a three-layer laminate with a thickness of 0.60 × 10 ^-3 m was used, and in addition to the top film based on acrylic resin with a thickness of 0.20 × 10 ^-3 m and lying beneath it, a decor layer with a thickness of 0.15 × 10 ^-3 m, between the carrier layer 1 (Fig. 1-Fig. 4), an additional film based on melamine resin with a thickness of 0.25 × 10 ^-3 m was added, reinforcing the resistance of the protective layer 4 (Figure 2-Figure 4) to the effects of the external environment on the floor surface. The back layer 5 (FIG. 2-FIG. 4) was made of melamine-impregnated paper and its thickness was 0.40 × 10 ⁻³ m.

The groove 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 a fixing spike 6 (Fig.2-b) of the recess so that the surface of the lower lip was executed with a curvature of 1 / R equal to 0.33. The spikes 6 (FIG. 2-b) in response to the milled grooves 2 (FIG. 1 and FIG. 3) in the form of a spring retaining tab were also formed by milling on the opposite ends of the same panel.

Assembling a floating floor with an area of 10 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 2 (Figure 1) of the long side of the panel was facing away from the wall of the room. To close the spike 6 (Fig.2-b) and the groove 2 (Fig.3) of 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 of the spike 6 (Fig.2-b) and the groove 2 (Fig. 3) of the short ends of the rallying panels by approximately 45 ° and with a force F (Fig. 3) of 9-10 kg, a spring-loaded locking tab was inserted into the recess of the groove 2 (Fig. 3), while simultaneously leading the articulated panel to smoothly turn into 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 (Figure 4) of the panels.

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 6 (Figure 2-b) to the groove 2 (Figure 3) 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 6 (Fig.2-b) into the groove of the groove 2 (Fig.3), 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 (Figure 4 ) Similarly, the installation of the entire floor was carried out.

After completing the laying of the last row of assembled from rectangular panels without glue flooring, in which groove 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 brand, 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 floor panels with the proposed profile of the groove 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 - 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 medium-density fiberboard (MDF) of 6 mm thickness was selected. As a protective layer 4 (FIG. 2, FIG. 3 and FIG. 4), a two-layer laminate with a thickness of 0.5 × 10 ⁻³ m was used, the thickness of the decor layer being 0.25 × 10 ⁻³ m and the film thickness being the base of the acrylic resin was 0.25 × 10 ^-3 m. The backing layer 5 (FIG. 2-FIG. 4) was made of unrefined paper also with a thickness of 0.50 × 10 ^-3 m.

Groove 2 (Figure 1) on the first of the ends (in this case, the end of the long side of the rallying panels) was milled in the form of a fixing spike recess so that the surface of the lower jaw was made with a 1 / R curvature equal to 0.45. Response to the described groove 2 (Fig. 1), the spike 6 (Fig. 2-b) in the form of a spring-loaded fixing tab 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 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 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 2 (Figure 3) was facing away from the wall of the room. Then, each of the panels of the second row was alternately oriented with a spike 6 (Figure 2-b) to the groove 2 (Figure 3) 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 3) equal to 9-10 kg introduced the spring retaining tab of the spike 6 (Fig.2-b) in the recess of the groove 2 (Fig.3) at the same time as this smooth rotation, bringing the articulated panel into a horizontal position. After laying the second panel of the 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 strokes of the rubberized hammer or an end metal mandrel was used, allowing the use of a metal 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, 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 averaged measurement results of the visible opening of the seam of the assembled from rectangular floor panels with the proposed design of the groove 2 (Figure 1) are presented in Table No. 3.
