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.

Known typesetting flooring [1], the wooden elements of which are rallied (mechanically combined) by means of a glueless end lock consisting of a rectangular groove and a spike mating to it, which are performed on the abutted ends of the mentioned wooden flooring elements.

The disadvantage of this analogue is the possibility of using an analog device only in narrow intervals of temperature and humidity due to warping of the flooring due to the absence in the design of the end lock assembly to compensate for seasonal variations in temperature and / or humidity of the gaps.

Also known is the design of the assembly of a glueless mechanical lock [2] connected to a continuous floor covering of panels. The aforementioned panels are rallied by means of a common groove-type end-face lock consisting of a rectangular groove and a return spike located at the bottom of the ends of the joined panels. In addition, the end lock contains a second pair of tongue-and-grooves for additional glueless joints made on the same joined ends of the panels, respectively, in the form of a figured groove and a corresponding figured spike.

The disadvantage of this analogue is the possibility of using an analog device only in narrow intervals of temperature and humidity due to warping of the flooring due to the absence of a gap element in the bottom of the end lock assembly to compensate for these external influences.

The closest to the proposed technical essence and the achieved result is the well-known solution [3], which disclosed the design of the mechanical end lock for connecting rigid rectangular panels that are scattered during the manufacturing process into a continuous floor covering. The end lock assembly is formed by the interaction of the first and second rectangular rigid panels, each of which is made of at least three functionally different layers, sequentially fastened together from top to bottom in a vertical plane. In this case, the first of the rectangular rigid panels is provided at the end with means of mechanical connection of the groove type, and the second of the rectangular rigid panels contains at the end adjacent to the end of the first rigid rectangular panel, the response means of mechanical connection of the spike type. To form a mechanical connection of these panels, a flexible tongue is used in the end lock assembly, which effectively distances the surfaces of the locking elements (tongues of the spike and all the groove lips) in the bottom of these panels. This technical solution is taken as a prototype.

The disadvantage of the prototype is the possibility of using an analog device only in relatively narrow ranges of temperature and humidity due to warping of the flooring due to the vast contact area (due to the use of a flexible tongue in the design of the end lock assembly) of the surface of the end lock elements with the ambient atmosphere, temperature and relative whose moisture is subject to significant seasonal fluctuations.

The task to which the creation of the claimed utility model is directed is to expand the geography of the application of laminated floor coverings (formed from laminated panels) to areas with large seasonal variations in temperature and / or relative humidity of the environment.

The expected technical result consists in expanding the temperature range of the operation of the claimed device.

The specified technical result is achieved by the fact that in the structural element of the end lock assembly 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 fastened together from top to bottom in a vertical planes, 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 w of stiff panels contains, at the end adjacent to the end of the first rigid rectangular panel, a spike-type mechanical connection, a groove is made at the end of the first of the rectangular rigid panels in the form of a profiled recess formed by the surface of the upper sponge, the surface of the lower sponge connecting them to the surface of the arch and, essentially vertical end surface, and the spike is made in the form of a mating groove of a profiled foot placed on the end of the second of the rectangular rigid panels adjacent to the first of rectangular rigid panels, while the end surfaces of the first and second rectangular rigid panels under the profiled foot are spaced at a distance equal to one of the values of the interval from 5 × 10 ^-3 m to 7 × 10 ^-3 m.

The claimed utility model is illustrated in the drawing. Figure 1 schematically shows a vertical section of the mechanical lock of the system of glueless connection of floor panels with the proposed structural element of the mechanical lock assembly.

The list of positions:

1. The protective layer.

11. The protective layer of the first panel.

12. The protective layer of the second panel.

2. The bearing layer.

21. The carrier layer of the first panel.

22. The carrier layer of the second panel.

3. The backing layer.

31. The backing layer of the first panel.

32. The backing layer of the second panel.

4. Thorn.

5. The groove.

6. Slotted structural element of the end lock assembly.

The mechanical cohesion of the rectangular rigid panels is ensured with the participation of the proposed design of the end lock assembly of the glueless system of the elements forming the floor covering.

The surface of each of the panels mentioned above, the opposite surface in contact with the subfloor (in other words, the back of the floor), is provided with a protective layer, i.e. on the surface of the first floor panel, a protective layer of the first floor panel 11 is formed (FIG. 1), and on the surface of the second floor panel, a protective layer of the second floor panel 12 is formed (FIG. 1).

In the case of a protective layer in the form of a two-layer laminate, the latter on the surface of the first floor panel 11 (Fig. 1) is a decor layer (painted and / or embossed decorative coating) over which a high-strength film is formed (in particular, reinforced with abrasive powder, for example Al ₂ O ₃ ), preferably based on melamine or acrylic resin. The structure of the protective layer 12 (FIG. 1) on the surface of the second floor panel is identical to the structure of the protective layer of the first panel 11 (FIG. 1).

In the case of the protective layer in the form of a composite laminate, the latter on the surface of the first floor panel 11 (Figure 1) is a base layer based on melamine or acrylic resin, on the surface of which a decor layer is thermally fixed. And the decor layer, in turn, is coated with a high-strength (in the sense of reinforcing with abrasive particles, for example, Al ₂ O ₃ powder) film, preferably also based on melamine or acrylic resin. The structure of the composite laminate on the surface of the second panel 12 (FIG. 1) for the floor is identical to the structure of the protective layer of the first panel 11 (FIG. 1).

In all of the above cases, the protective layers of the panels are fixed to the surface of the carrier layer, in this case, the carrier layers of the first panel 21 (Figure 1) and the second panel 22 (Figure 1), respectively. The carrier layer of the first 21 (Figure 1) and the carrier layer of the second 22 (Figure 1) of the panels are made of medium-density fiberboard (Medium Density Fibroboard) or high (High Density Fibroboard) density.

With the back side of the carrier layer 21 (Figure 1) and 22 (Figure 1), fasten the revolving layer of the first 31 (Fig. 1) and the revolving layer of the second 32 (Fig. 1) panels. Unrefined or impregnated with resin (preferably melamine or acrylic resin) paper is typically used as the backing layer material. Functionally, the reverse layer 31 and 32 (Fig. 1) is designed to compensate for mechanical stresses in the carrier layer 21 and 22 (Fig. 1) arising due to the presence on its surface completely different from the carrier layer in structure (and, accordingly, in mechanical characteristics) the protective layer 11 and 12 (Figure 1).

The glueless articulation of the panels in the claimed device is ensured due to the fact that on their vertical (i.e., end) surfaces, tool milling methods form means of mechanical connection (end lock assembly) of the groove-tongue type. In this case, the spike 4 (FIG. 1) is made in the form of a spring fixing tab, the surface of which contacts the surfaces of the upper and lower jaws of the locking groove 5 (FIG. 1) so that a slotted structural element is formed under the spring locking tab of the spike between the first and second panels node mechanical lock 6 (Figure 1). In other words, the end parts of the first and second articulated panels under the spike foot are spaced apart by a distance equal to one of the values of the interval from 5 × 10 ^-3 m to 7 × 10 ^-3 m.

Example No. 1

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. Use the above panels with a protective layer 11 and 12 (Figure 1) in the form of a bilayer laminate with a thickness of 1 × 10 ^-3 m, and the thickness of the decor layer in it is 0.50 × 10 ^-3 m, and the film thickness is based on melamine resin 0.50 × 10 ^-3 m. As the carrier layer 21 and 22 (FIG. 1), a high-density fiberboard (HDF) of 7 mm thickness was chosen. The back layers 31 and 32 (FIG. 1) were made of unrefined paper with a thickness of 1 × 10 ^-3 m

The groove 5 (Figure 1) is performed so that the surface of the upper jaw has zero curvature and is oriented parallel to the plane of the surface of the rectangular rigid panel, and the surface of the lower jaw, on the contrary, is made with a curvature 1 / R equal to 0.45. In this case, the groove 5 (FIG. 1) on the first of the ends of the long side of the panel was milled in the form of a recess fixing the response spike 4 (FIG. 1) so that under the spring-loaded fixing tab of the spike 4 (FIG. 1) between the first and second panels during assembly a slotted structural element of the end lock assembly 6 is formed (FIG. 1). In fact, in this example, the end parts of the first and second articulated panels under the foot of the spike 4 (Fig. 1) are spaced apart by a distance of 7 × 10 ⁻³ m.

Assembling a floating floor in a room with an area of 8 m ² from panels with the described design of the end lock was performed with a shift in the position of the ends of each next stacked row by half the length of the panel used for it. Initially, the first row of rectangular rigid panels was laid along the selected wall of the room so that the ends of the short side adjoin each other, and the groove 5 (Figure 1) is facing away from the wall of the room. Then, each of the panels of the second row was alternately oriented with a spike 4 (Fig. 1) to the groove 5 (Fig. 1) of the previously laid row, the articulated panel was tilted at an angle of about 45 ° to the surface of the subfloor (i.e., to the horizontal plane) and with a force of about 9-10 kg introduced the spring retaining tab of the spike 4 (Figure 1) into the groove of the groove 5 (Figure 1) 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.

Having completed the laying of the last row of assembled (without the use of glue) from rectangular rigid floor panels, we examined the permissible boundaries of the temperature range of its operation. The admissibility assessment was carried out by measuring the visible opening of the seam between the installed panels with the proposed design of the end lock assembly and the prototype, which should not exceed the value of 0.2 mm. For measurements, an optical non-contact micrometer of the RF651-5 brand was used, which provides a linear measurement error of up to 5 mm no more than 10 μm.

The accuracy of setting the floor temperature using thermoelectric elements based on the Peltier effect was 0.5 ° C. The averaged results of measurements of the visible opening of a seam of a panel floor assembled from rectangular panels and subjected to a change in temperature are presented in Table No. 1.

Table number 1 No. p / p Object of research The average visible opening of the seam between the panels, mm Temperature range one Prototype device 0.2 14 ° C - 45 ° C 2 Claimed device 0.2 2 ° C - 55 ° C

As follows from Table No. 1, the proposed device allows to implement the claimed technical result in the form of expanding the boundaries of the temperature range of operation.

Example No. 2

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. Apply the above panels with a protective layer 11 and 12 (Figure 1) in the form of a two-layer laminate with a thickness of 0.5 × 10 ^-3 m, and the thickness of the decor layer in it is 0.25 × 10 ^-3 m, and the film thickness is based on acrylic resin 0.25 × 10 ^-3 m. As the carrier layer 21 and 22 (Figure 1) used medium density fiberboard (MDF) with a thickness of 6 mm The reverse layers 31 and 32 (FIG. 1) were made of acrylic resin impregnated paper with a thickness of 0.5 × 10 ⁻³ m.

Groove 5 (Figure 1) is performed so that the surface of the upper jaw has zero curvature and is oriented parallel to the plane of the surface of the rectangular rigid panel, and the surface of the lower jaw, on the contrary, is made with a 1 / R curvature of 0.12. In this case, the groove 5 (FIG. 1) on the first of the ends of the long side of the panel was milled in the form of a recess fixing the response spike 4 (FIG. 1) so that under the spring-loaded fixing tab of the spike 4 (FIG. 1) between the first and second panels during assembly a slotted structural element of the end lock assembly 6 is formed (FIG. 1). In this example, the end parts of the first and second articulated panels under the foot of the spike 4 (Figure 1) were spaced apart by a distance of 6 × 10 ^-3 m.

Assembling a floating floor in a room with an area of 9 m ² from panels with the described design of the end lock was performed with a shift in the position of the ends of each next stacked row by half the length of the panel used for it. Initially, the first row of rectangular rigid panels was laid along the selected wall of the room so that the ends of the short side adjoin each other, and the groove 5 (Figure 1) is facing away from the wall of the room. Then, each of the panels of the second row was alternately oriented with a spike 4 (Fig. 1) to the groove 5 (Fig. 1) of the previously laid row, the articulated panel was tilted at an angle of about 45 ° to the surface of the subfloor (i.e., to the horizontal plane) and with a force of about 9-10 kg introduced the spring retaining tab of the spike 4 (Figure 1) into the groove of the groove 5 (Figure 1) 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.

Having completed the laying of the last row of assembled (without the use of glue) from rectangular floor panels, we examined the permissible limits of the temperature range of operation. The admissibility assessment was carried out by measuring the visible opening of the seam between the installed panels with the proposed design of the end lock assembly and the prototype, which should not exceed the value of 0.2 mm. For measurements, an optical non-contact micrometer of the RF651-5 brand was used, which provides a linear measurement error of up to 5 mm no more than 10 μm.

The accuracy of setting the floor temperature using thermoelectric elements based on the Peltier effect was 0.5 ° C. The average results of measurements of the visible opening of the seam of the assembled from rectangular panels and subjected to a change in temperature of the panel floor are presented in Table No. 2.

As follows from Table No. 2, the proposed device allows to implement the claimed technical result in the form of expanding the boundaries of the temperature range of operation.

Example No. 3

Rectangular rigid panels are used for glueless floor construction with the following dimensions: length - 1290 mm, width - 194 mm, thickness - 8 mm. Each of the panels is equipped with four spike-groove mechanical connection means formed at the ends of its opposite long sides. Use the above panels with a protective layer 11 and 12 (Figure 1) in the form of a three-layer composite laminate with a thickness of 1.2 × 10 ^-3 m, and the thickness of the base layer based on an acrylic film was 0.4 × 10 ^-3 m, the thickness of the decor layer was 0.4 × 10 ⁻³ m, and the thickness of the top melamine resin-based protective film was also 0.4 × 10 ⁻³ m.

As the carrier layer 21 and 22 (FIG. 1), a 6 mm thick high density fiberboard (HDF) was selected. The back layers 31 and 32 (FIG. 1) were made of crude paper 0.8 × 10 ⁻³ m thick.

The grooves 5 (Fig. 1) were made so that the surface of the upper jaw had zero curvature and was oriented parallel to the plane of the surface of the rectangular rigid panel, and the surface of the lower jaw, on the contrary, was made with a 1 / R curvature of 0.33. In this case, the groove 5 (Fig. 1) on the first of the ends of the panel was milled in the form of a recess fixing the response spike 4 (Fig. 1) so that under the spring-loaded fixing tab of the spike 4 (Fig. 1) a gap is formed between the first and second panels during assembly structural element of the mechanical lock assembly 6 (Fig. 1). In fact, in the third example, the end parts of the first and second articulated panels under the foot of the spike 4 (Figure 1) were spaced apart by a distance of 5 × 10 ^-3 m.

Assembling a floating floor with an area of 8 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 ends of the short side were adjacent to each other until they clicked, and the groove 5 (Figure 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. 1) into the recess of the groove 5 (FIG. 1), 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 glueless floor panels 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 subfloor, i.e. each of the panels of the second row was alternately oriented with a spike 4 (Fig. 1) to the groove 5 (Fig. 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 10-12 kg the spring-loaded fixing tab of the spike 4 was inserted (Figure 1) in the recess of the groove 5 (Figure 1), 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 entire floor was carried out.

Having completed the laying of the last row of assembled (without the use of glue) from rectangular floor panels, we examined the permissible limits of the temperature range of operation. The admissibility assessment was carried out by measuring the visible opening of the seam between the installed panels with the proposed design of the end lock assembly and the prototype, which should not exceed the value of 0.2 mm. For measurements, an optical non-contact micrometer of the RF651-5 brand was used, which provides a linear measurement error of up to 5 mm no more than 10 μm.

The accuracy of setting the floor temperature using thermoelectric elements based on the Peltier effect was 0.5 ° C. The average results of measurements of the visible opening of the seam of a panel floor assembled from rectangular panels and subjected to a change in temperature are presented in Table No. 3.
