State of the art

From the prior art (source RU 2232854 C2, E04F 15/02, publ. 07.20.2004), panel elements are known for which a groove is provided in the upper part of the tenon, a gap is provided between the holding crest and the furrow, the tenon and groove are also made with a gap. When panels are laid, glue is applied to the retaining groove, which is squeezed out during laying of the next panel, spreads over the gaps, fastening and sealing the joint, which prevents moisture from penetrating into the lower layers of wood and reliably fixes the panels. Reliable monolithic adhesive bonding is ensured due to the fact that between the retaining groove and the retaining crest a uniform cavity is created on the lower and front sides of the retaining crest relative to the spike, for uniform placement of glue. The configuration of the cavity, expressed in the equidistance of the materials of adjacent panels along its entire length, provides a uniform distribution of glue and a single thickness of the adhesive coating along the entire length of the cavity, which in turn ensures uniform and monolithic drying of the glue after laying the panels. Cavities in addition to fixing the connection also perform the function of sealing it. The use of smoothed rounded chamfers of the tenon, which allows the tenon to be inserted from the longitudinal side into the groove at an angle relative to the floor plane when laying the panel and laying without effort. The holding furrow has sloping chamfers made at an angle in cross section. In turn, the holding ridge also has sloping chamfers made at an angle. These chamfers on the retaining groove and the retaining ridge provide the ability to connect them effortlessly when laying the panel. They also create a point of force, a place of complete adherence of the panels, ensuring the panel is fixed in the horizontal plane relative to the previously laid panel along the longitudinal side. After laying two adjacent panels along the longitudinal side, two stress points are created between the connected panels, which prevent the panel from moving both horizontally and vertically relative to each other.

Moreover, this connection prevents the movement of the panels relative to each other in a horizontal plane. The transverse connection is fixed in the vertical plane by the longitudinal connection of adjacent rows of laid panels. At the same time, a gap is provided in the transverse connection in the lower part of the ridge for applying glue and sealing the connection along the longitudinal side of the panel. The transverse connection of the panels during simple assembly in the form of laying the ridge in the tongue has two force points that securely fix the transverse connection in the horizontal plane. In this case, the gap is used for applying glue, for fixing and sealing the transverse connection. At the bottom of the panel there are gaps that are necessary to compensate for the natural changes in the geometric dimensions of the wood.

Implementation of a utility model.

The panel element (1) is configured to connect to another panel element of the same type (1). Panel elements (1), can be made of both solid wood and a multilayer wooden structure based on FSF plywood, with a lamella made of hard wood. Each panel element (1) contains two longitudinal and two transverse edges. The longitudinal edges of the panel are made in the form of a groove (2) on one side and a spike (3) on the other side. In this case, the groove (2) has a retaining groove (4) in its upper side, and the spike (3) has a retaining ridge (5) on its lower side, which, when laid, is inserted into the retaining groove (4) to prevent the panels from moving relative to each other friend. The configuration of the retaining ridge (5) and the retaining groove (4) together with the tongue relief (3) allow the tongue of the other panel to be inserted into the groove (2) of the already installed panel along the longitudinal side at an angle with respect to the laying plane with the possibility of rotation on the longitudinal edge and around her down into the stacking plane. In this case, the holding ridge (5) is inserted into the holding groove (4), fixing the panels and preventing the panels from moving relative to each other in horizontal and vertical planes. Also, a groove (6) is provided in the upper part of the spike (3), a gap (7) is provided between the retaining ridge (5) and the furrow (4), the spike (3) and the groove (2) are also made with a gap (8). When panels are laid, glue (9) is applied to the retaining groove (4), which, when laying the next panel (1), is squeezed out, spreads over the gaps (6), (7) and (8), fastening and sealing the joint, which prevents penetration moisture in the lower layers of wood and reliably fixes panels. The two transverse edges of the panel element are made in the form of a simple dowel (1a) and a ridge (2a), which are connected by vertical laying on top of each other, which allows the panels (1) to be stacked alternately without first connecting the rows of panels. Moreover, this connection prevents the movement of the panels relative to each other in the horizontal plane. The transverse connection is fixed in the vertical plane by the longitudinal connection of adjacent rows of laid panels. At the same time, in the transverse connection in the lower part of the ridge (2a), a gap (3a) is provided for applying glue and sealing the connection along the longitudinal side of the panel.

The possibility, with insignificant physical effort, during the laying of the panels to obtain a reliable monolithic adhesive connection is ensured due to the fact that a uniform cavity (7) is created between the retaining groove and the retaining crest, on the lower and front sides of the retaining crest relative to the spike, for uniform placement of glue. The configuration of the cavity, expressed in the equidistance of the materials of adjacent panels along its entire length, provides a uniform distribution of glue and a single thickness of the adhesive coating along the entire length of the cavity, which in turn ensures uniform and monolithic drying of the glue after laying the panels. In the longitudinal connection, cavities (6, 7, 8) are provided for accommodating the adhesive composition, which, spreading, reliably fixes the connection. Cavities (6, 8), in addition to fixing the joint, also perform the function of sealing it, to prevent moisture from entering the lower layers of wood, which is especially important in cases of using a multilayer wooden structure in the manufacture of panels (1). The transverse connection of the panels during simple assembly in the form of laying the ridge (2a) into the tongue (1a), has two force points (13, 14) that securely fix the transverse connection in the horizontal plane. In this case, the gap (3a) is used for applying glue, for fixing and sealing the transverse connection. In general, the described configuration of joints, both along the longitudinal and transverse edges, provides a load on the adhesive composition, in the cavities (6, 7, 8, 3a), after laying the panels without additional external pressure, which allows the adhesive composition to effectively fasten the panels and fully perform the function of sealing the connection. The use of smooth rounded chamfers (9, 10) of the tenon (3), which allow the tenon to be inserted longitudinally into the groove (2) at an angle relative to the floor plane when laying the panel and laying without effort. The holding groove (4) has in cross section sloping chamfers (4a, 4b) made at an angle of 45 °. In turn, the holding ridge (5) also has sloping chamfers (5a, 5b) made at an angle of 45 °. These chamfers on the retaining groove and the retaining ridge provide the ability to connect them effortlessly when laying the panel. They also create a force point (11), a place of full fit of the panels, ensuring the panel is fixed in the horizontal plane relative to the previously laid panel along the longitudinal side. After laying two adjacent panels along the longitudinal side, two stress points are created between the connected panels (11, 12), which prevent the panel from moving both horizontally and vertically relative to each other. Both along the longitudinal and transverse sides of the joints in the lower side of the panel, the provided gaps (15, 16) are necessary to compensate for natural changes in the geometric dimensions of the wood.

The claimed technical solution reduces the effort exerted during the installation of panels without losing the reliability of the connection, provided by the efficiency of fastening and sealing the connection of identical panel elements by preventing the panels from moving relative to each other both along the longitudinal and transverse sides of the connection, moisture penetration into the lower layers wood and providing a load on the adhesive composition.
