Description
Elément de parquet. La présente invention a pour objet un élément de parquet, par exemple une lamelle de parquet.
Cet élément est caractérisé en ce qu'il comporte, dans son épaisseur, plusieurs cou ches parallèles de bois d'essences différentes, superposées et solidaires les unes des autres. L'une au moins de ces couches peut être en bois plein et une autre en bois contre-plaqué.
Le dessin annexé représente,<B>à</B> titre d'exemple, une lamelle de parquet conforme <B>à</B> l'invention.
La fig. <B>1</B> est une coupe longitudinale de cette lamelle, et La fig. 2 en est une coupe transversale. La lamelle représentée est composée (Pune pièce<B>10</B> généralement en bois dur, par exem ple en chêne, cette pièce étant placée du côté de travail de la lamelle, et d'une pièce <B>11</B> en bois contre-plaqué, par exemple en okumé, placée sur l'autre face de la lamelle.
Les pièces sont rendues solidaires l'une de l'autre par n'importe quel procédé (col lage, etc.). Elles ont leurs faces de, contact parallèles, de telle soi-te que la lainelle com porte des couches parallùle>s de bois d'es sences différentes.
La lamelle présente, comme les lamelles ordinaires, des rainures 12 pour son asseiii- blage avec les éléments voisins du parquet. La pièce<B>10</B> peut, par exemple, avoir<B>8 à</B> <B>10</B> mm d'épaisseur et former approximative ment les '/5 de la lamelle, les 1/6 restants étant constitués par la pièce<B>Il</B> en trois par ties égales contre-plaquées. La pièce<B>11,</B> au lieu d'être entièrement en bois de même essence, pourrait être en partie cri sapin et en partie en okumé par exemple.
Dans ce, but, la feuille externe du contre-plaqué petit être en sapin, de telle sorte que l'élément est composé de trois couches<B>de</B> bois d'es sences différentes.
L'élément de parquet, objet de l'invention, présente les avantages suivants découlant de sa structure en plusieurs couches: <B>1.</B> Il est plus stable que les éléments connus, au point de vue de la dilatation et de la contraction par suite de différences de température oui d'humidité soit de Pair, soit de la matière sur laquelle il est placé, par exemple des scories ou autres.
2. L'élément ne se voile pas<B>à</B> la longue, <B>ce</B> qui évite une rectification par rabotage des parquets une fois ces derniers posés et permet de fabriquer les éléments<B>à</B> l'avance. En outre, les parquets rectifiés présentent des éléments amincis par endroits, éléments qui fléchissent sous une charge et qui ris quent par conséquent de provoquer des grin cements.
<B>3.</B> L'élément est plus léger que celui fait entièrement en bois dur.
4. Il est moins conducteur du son, par suite de sa structure hétérogène, que<B>l'élé-</B> ment en une seule pièce.
<B>5.</B> En cas d'usure localisée, la couche su périeure seule de l'élément est<B>à</B> remplacer, ce qui simplifie considérablement le travail.
Element of parquet. The present invention relates to a parquet element, for example a parquet strip.
This element is characterized in that it comprises, in its thickness, several parallel layers of wood of different species, superimposed and integral with one another. At least one of these layers can be solid wood and another one of plywood.
The appended drawing represents, <B> by </B> by way of example, a parquet strip conforming <B> to </B> the invention.
Fig. <B> 1 </B> is a longitudinal section of this lamella, and fig. 2 is a cross section. The slat shown is composed (Pune part <B> 10 </B> generally in hard wood, for example oak, this part being placed on the working side of the slat, and a part <B> 11 </ B> in plywood, for example in okumé, placed on the other side of the strip.
The parts are made integral with one another by any process (gluing, etc.). They have their faces of parallel contact, so that the woolen comprises parallel layers of wood of different species.
The strip has, like ordinary strips, grooves 12 for its seating with the neighboring elements of the parquet. The part <B> 10 </B> can, for example, be <B> 8 to </B> <B> 10 </B> mm thick and form approximately the '/ 5 of the strip, the 1/6 remaining being formed by the piece <B> II </B> in three equal parts plywood. The room <B> 11, </B> instead of being entirely in wood of the same species, could be partly fir cry and partly okumé for example.
For this purpose, the outer sheet of the plywood can be made of fir, so that the element is composed of three layers of <B> </B> wood of different species.
The parquet element, object of the invention, has the following advantages resulting from its structure in several layers: <B> 1. </B> It is more stable than the known elements, from the point of view of expansion and contraction as a result of temperature or humidity differences either of the air or of the material on which it is placed, for example slag or the like.
2. The element does not veil <B> to </B> in the long run, <B> this </B> which avoids a rectification by planing of the floors once they have been installed and allows the <B> elements to be manufactured. in advance. In addition, rectified floors have elements thinned in places, elements which flex under load and which therefore risk causing squeaking.
<B> 3. </B> The element is lighter than the one made entirely of hardwood.
4. It is less conductive of sound, owing to its heterogeneous structure, than the <B> element </B> in one piece.
<B> 5. </B> In the event of localized wear, the upper layer alone of the element is <B> to </B> replaced, which considerably simplifies the work.
