Abstract
The invention relates to the field of construction, in particular to the connection of floorboards. The technical problem is that of increasing the performance of flooring by increasing the stability of a specified position of abutting boards under fluctuations in temperature and humidity. The flooring comprises floorboards having connecting means on at least two opposite edges, and a base and a fastening element. A groove is formed on the connecting means of the one edge, said groove being formed by an upper tenon and a lower tenon, which have internal surfaces which are inclined into the board body and form a trapezoidal profile in cross section. The height of the upper tenon is greater than the lower tenon. At the end of the tenon there is a surface which is inclined towards the upper plane of the board. An upper mortise and a lower mortise are formed on the connecting means of the other edge, the inclined surfaces of which mortises form a ridge with dimensions corresponding to the dimensions of the groove. A channel is formed from the centre of the surface of the ridge and as far as the lower plane of the board, said channel being inclined into the board body and having a fastening element arranged therein.

Недостатком данного изобретения, является не технологичность сборки, влекущая за собой ухудшение эксплуатационных свойств, снижение качества данного полового настила, а именно, оттого, что крепежный элемент расположен в углу верхнего выреза, то есть рядом с основанием верхнего выреза, возможно повреждение кромки при сборке. Так же при усушке элементов настила образуются усадочные щели, а так как посадка в направлении перпендикулярно верхней плоскости полового покрытия ограничена лишь парой сопрягаемых мест, возможно смещение соединительных средств относительно друг друга по вертикали, что ведет к образованию заметного уступа в стыках. При впитывании влаги, в том числе из атмосферы, происходит разбухание досок, что приводит к их короблению, в частности в местах стыковки досок, это так же приводит к возникновению уступа. Все это ухудшает эксплуатационные
свойства полового настила, снижает его качество. The disadvantage of this invention is not the manufacturability of the assembly, entailing a deterioration in the operational properties, a decrease in the quality of this flooring, namely, because the fastener is located in the corner of the upper cutout, that is, near the base of the upper cutout, edge damage during assembly is possible. Also, during shrinkage of the flooring elements, shrinkage gaps are formed, and since landing in the direction perpendicular to the upper plane of the flooring is limited only by a pair of mating places, it is possible to shift the connecting means relative to each other vertically, which leads to the formation of a noticeable ledge at the joints. When moisture is absorbed, including from the atmosphere, the boards swell, which leads to their warping, in particular at the joining of the boards, this also leads to a ledge. All this worsens operational properties of flooring, reduces its quality.

Половой настил включает в себя половые доски 1, имеющие на двух противоположных кромках (фиг.З) соединительные средства 2 и 3, основание 4, и крепежный элемент 5, установленный в наклонном канале 6. На соединительном средстве 2 (фиг.2) выполнен паз 7, образованный верхним 8 и нижним 9 шипами, имеющими внутренние The flooring includes floorboards 1 having connecting means 2 and 3 on two opposite edges (FIG. 3), a base 4, and a fastener 5 mounted in an inclined channel 6. A groove is made on the connecting means 2 (FIG. 2) 7 formed by the upper 8 and lower 9 spikes having internal
наклоненные в тело доски поверхности 10 и 11, которые образуют в поперечном сечении трапецеидальный профиль, при этом высота верхнего шипа 8, примерно, в два раза больше нижнего шипа 9. На торце 12, шипа 8 имеется поверхность 13, которая наклонена к верхней плоскости доски 1. На соединительном средстве 3 (фиг.1) выполнен верхний 14 и нижний 15 вырезы, наклонные поверхности 16 и 17 которых образуют гребень 18 с размерами соответствующими размерам паза 7 расположенного на соединительном средстве 2, при этом поверхность 19 выполнена параллельно поверхности 13. От центра поверхности 16 до нижней плоскости доски выполнен наклоненный в тело доски канал 6 внутри которого располагается крепежный элемент 5 для крепления доски к основанию 4. (фиг.З, 6) На поверхности *19 может быть выполнена фаска 20, расположенная под углом к верхней плоскости доски, равному углу наклона поверхности 13 На поверхности 16 и 10 (фиг.4, 5) могут быть выполнены сопрягаемые между собой плоскости 21 и 22 расположенные параллельно surfaces 10 and 11 inclined into the body of the board, which form a trapezoidal profile in cross section, while the height of the upper tenon 8 is approximately two times greater than the lower tenon 9. At the end 12 of the tenon 8 there is a surface 13 that is inclined to the upper plane of the board 1. On the connecting means 3 (Fig. 1), the upper 14 and lower 15 cutouts are made, the inclined surfaces 16 and 17 of which form a ridge 18 with dimensions corresponding to the dimensions of the groove 7 located on the connecting means 2, while the surface 19 is parallel to the surface 13. From the center of the surface 16 to the lower plane of the board, a channel 6 is inclined into the board body, inside of which there is a fastening element 5 for fastening the board to the base 4. (Fig. 3, 6) On surface * 19 a chamfer 20 can be made, located at an angle to the top the plane of the board equal to the angle of inclination of the surface 13 On the surface 16 and 10 (Figs. 4, 5), mating planes 21 and 22 located parallel to each other can be made
относительно верхней плоскости доски. Так же для наиболее плотного соединения з
сопрягаемых поверхностей 13 и 19 за счет разности размеров, между поверхностями 23 и 24, поверхностями 25 и 26 выполнены зазоры, размеры которых равны 1,0... 2,0 мм. Сборка полового настила из досок настоящей полезной модели происходит в следующем порядке. К основанию, по разметке, на расстоянии 10...15 мм от стены закрепляются кляймеры (на чертеже не показано), и к ним крепится первая доска 1, при этом паз 7 обращен к стене. Затем через наклонные каналы б крепежным элементом 5, доска крепится к основанию 4, при этом каналы 6 могут быть выполнены заранее или непосредственно перед установкой доски. Следующая доска стыкуется кромкой с пазом к предыдущей доске и также крепится крепежным элементом к основанию, формируя половой настил. relative to the top plane of the board. Also for the most tight connection mating surfaces 13 and 19 due to the difference in size between the surfaces 23 and 24, surfaces 25 and 26, gaps are made, the sizes of which are equal to 1.0 ... 2.0 mm. Assembling flooring from the boards of this utility model occurs in the following order. Kleimers are fixed to the base, according to the marking, at a distance of 10 ... 15 mm from the wall (not shown in the drawing), and the first board 1 is attached to them, with the groove 7 facing the wall. Then, through the inclined channels b by the fastening element 5, the board is attached to the base 4, while the channels 6 can be made in advance or immediately before installing the board. The next board joins the edge with the groove to the previous board and is also fastened with a fastener to the base, forming a flooring.
Таким образом, новая совокупность существенных признаков заявленного решения позволила обеспечить очень точную пригонку верхних плоскостей смежных стыкуемых досок. За счет же разности в размерах между гребнем и пазом, нижним шипом и нижним вырезом обеспечивает, при стыковке, плотное прилегание сопрягаемых поверхностей. Так же за счет того, что сопрягаемые поверхности расположены в разнонаправленных плоскостях, достигается повышенная стабильность заданного относительного положения стыкуемых досок при колебаниях температур и влажности. Преимуществом так же является и то, что крепежный элемент располагается в середине увеличенной верхней поверхности гребня, что улучшает технологичность сборки полового покрытия, и соответственно, улучается качество и эксплуатационные свойства полового покрытия.
Thus, a new set of essential features of the claimed solution made it possible to ensure a very accurate fit of the upper planes of adjacent mating boards. Due to the difference in size between the ridge and the groove, the lower spike and the lower neckline, it ensures, upon joining, a snug fit between the mating surfaces. Also, due to the fact that the mating surfaces are located in multidirectional planes, increased stability of a given relative position of the mating boards under temperature and humidity fluctuations is achieved. The advantage is also that the fastener is located in the middle of the enlarged upper surface of the ridge, which improves the manufacturability of the flooring assembly, and accordingly, the quality and performance of the flooring is improved.
