  PROCEDE DE FABRICATION SOUS COMPRESSION D'UNE PLAQUE DE CONSTRUCTION, AINSI QUE 
PLAQUE DE CONSTRUCTION FABRIQUEE SELON CE PROCEDE. 



   La présente invention a pour objet un procédé de fabrication sous compression d'une plaque de construction du type ciment de laine de bois, dans laquelle plaque   des.canaux   sont prévus au moyen de noyaux espa- cés ayant une section transversale telle que l'espace entre deux noyaux voisins diminue régulièrement à partir du   côté   supérieur et du côté infé- rieur de ces noyaux vers le milieu desdits noyaux. 



   De ce procédé connu, selon lequel-on se sert de noyaux ayant des saillies, le procédé suivant la présente invention se distingue, parce qu'on emploie des noyaux ayant une surface extérieure lisse, de sorte que par la coopération de la pression et des noyaux le matériau est comprimé dans la direction de pression aussi bien que dans une direction transversa- le à ladite direction de pression et à la direction longitudinale des noyaux. 



   Le matériau est donc comprimé de deux cotés. 



   Bien que par la compression de deux côtés la quantité de ma- tériau employée pour remplir les espaces entre les noyaux soit proportion- nellement un peu plus grande que la quantité nécessaire pour remplir lesdits espaces dans la plaque de construction bien connue ayant des canaux, on em- ploie au total, moins de matériau que ce serait nécessaire pour une plaque massive des mêmes   dimensionso   
La solidité des sections de la plaque entre les conduits ou les noyaux augmente cependant considérablement, de sorte que la solidité de la plaque entière augmente   égalemento   
L'attention est attirée sur le fait qu'une plaque de construc-

 tion ayant des canaux de l'espèce., à laquelle la présente invention se rap-   portée   cependant revêtue d'au moins une couche de renfort,

   est connue en soie Mais les plaques connues ne sont pas fabriquées sous compression du maté- riau, bien que la pression de plaques du type ciment de laine de bois soit connueo 
La description qui va suivre explique l'invention par rapport au dessin. 



   La figo 1 représente une vue d'une plaque de construction ayant des canaux prévus dans la plaque; la figo 2 représente une coupe par II-II dans la fige 1; la figo 3 représente, à plus grande échelle, une section trans- versale par la plaque pendant la fabrication de la dite plaque. 



   La plaque de construction 1 suivant les figures 1 et 2 fabri- quée en ciment de laine de bois est munie de canaux longitudinaux 2 et de rainures 3. 



   La fabrication de la plaque a lieu de la manière suivante 
Après que (voir la figo 3) des tubes 4 ont été disposés dans le moulele ciment de laine de bois 7 prévu autour desdits tubes est com- primé simultanément du côté supérieur par la plaque 5 et du côté inférieur par la plaque 60 
Quand le matériau est comprimé dans la direction des flèches.9 ledit matériau sera comprimé en même temps entre les tubes 4. Pour facili- ter le glissement du matériau.. on graisse les tubes de préférenceo 
Ainsi on obtient entre les tubes des zones d'une grande soli- dité, lesquelles zones sont en grande partie en forme de Io

  COMPRESSIONAL MANUFACTURING PROCESS OF A CONSTRUCTION PLATE, AS WELL AS
CONSTRUCTION PLATE MANUFACTURED ACCORDING TO THIS PROCEDURE.



   The present invention relates to a method of manufacturing under compression a building plate of the cement type of wood wool, in which the plate channels are provided by means of spaced cores having a cross section such as the space. between two neighboring cores decreases regularly from the upper side and the lower side of these cores towards the middle of said cores.



   From this known method, in which cores having protrusions are used, the method according to the present invention differs, because cores having a smooth outer surface are employed, so that by the cooperation of the pressure and cores the material is compressed in the direction of pressure as well as in a direction transverse to said direction of pressure and to the longitudinal direction of the cores.



   The material is therefore compressed from two sides.



   Although by two-sided compression the amount of material employed to fill the spaces between the cores is proportionately somewhat greater than the amount needed to fill said spaces in the well-known building plate having channels, it is uses a total of less material than would be necessary for a massive plate of the same dimensions
The strength of the sections of the plate between the conduits or cores, however, increases considerably, so that the strength of the entire plate also increases.
Attention is drawn to the fact that a building plate

 tion having channels of the species, to which the present invention relates however coated with at least one reinforcing layer,

   is known in silk But known plates are not made under compression of the material, although the pressure of wood wool cement type plates is known.
The following description explains the invention with respect to the drawing.



   Figo 1 shows a view of a building plate having channels provided in the plate; Fig 2 shows a section through II-II in fig 1; FIG. 3 shows, on a larger scale, a cross section through the plate during the manufacture of said plate.



   The building plate 1 according to figures 1 and 2 made of wood wool cement is provided with longitudinal channels 2 and grooves 3.



   The manufacture of the plate takes place as follows
After (see fig. 3) tubes 4 have been placed in the mold, the wood wool cement 7 provided around said tubes is compressed simultaneously on the upper side by the plate 5 and on the lower side by the plate 60
When the material is compressed in the direction of the arrows. 9 said material will be compressed at the same time between the tubes 4. To facilitate the sliding of the material .. the tubes are preferably greased.
In this way, zones of great solidity are obtained between the tubes, which zones are largely in the form of Io
CLAIMS.



   1. A method of manufacturing under compression a building board of the cement type of wood wool., In which the building board are provided channels by means of spaced cores having a cross section such as space between two neighboring cores decreases regularly from the upper side and the lower side of said cores towards their center, characterized in that cores having a smooth outer surface such that, by the cooperation of the pressure and the cores, the material is compressed in the direction of pressure as well as in a direction transverse to this direction of pressure and to the longitudinal direction of the cores.
