Description

  

  Procédé de fabrication d'un élément de construction en plâtre, et élément de  a construction en     plâtre    obtenu suivant ce procédé.    La présente invention se rapporte à un  procédé de fabrication d'un élément de cons  truction en plâtre ainsi qu'à un élément de  construction en plâtre obtenu suivant ce  procédé.  



  Ce procédé est caractérisé en ce que l'on  coule, autour d'une armature, du plâtre gâché  avec de l'eau dans laquelle on a dissous de  la colle, le tout dans le but d'obtenir un élé  ment suffisamment résistant pour supporter  le transport sans se détériorer et pour être  employé à la confection des plafonds et des  galandages sans qu'il soit nécessaire de le  recouvrir, après sa pose, d'une nouvelle cou  che de plâtre.  



  Ce procédé pourra être mis en     oeuvre,    par  exemple de la façon suivante : Dans le fond  d'un moule, on dispose une couche de plâtre  gâché avec de l'eau dans laquelle on a au  préalable dissous de la colle, puis on dispose  sur cette couche une rangée de roseaux for  mant armature que l'on recouvre d'une nou  velle couche de plâtre également gâché avec  de l'eau dans laquelle on a dissous de la    colle, puis on laisse sécher le tout. On peut  ainsi obtenir un élément en forme de planche  tel que représenté en     cc    aux     fig.    1 et 2, en  coupe transversale et en plan<B>;</B> b sont les  roseaux.  



  Pour que le plâtre se durcisse suffisam  ment, il est connu qu'il est nécessaire de le  gâcher avec     suffisamment    d'eau, mais alors,  la prise se fait si rapidement que très sou  vent le plâtre se durcit avant qu'on ait eu  le temps de l'introduire dans le moule ; c'est  pour cette raison que, dans la fabrication  actuelle des planches â roseaux, utilisées  dans la construction, on gâche le plâtre avec       1111    minimum d'eau. On a ainsi tout le temps  nécessaire pour le moulage du plâtre, mais  la planche, une fois sèche, n'est pas assez  résistante , presque toujours elle se détériore  pendant le transport; en outre, il faut, après  la pose, la recouvrir d'une couche de plâtre  qu'on a gâché avec suffisamment d'eau pour  qu'elle soit dure.

   Mais cette eau ainsi ab  sorbée, au lieu de durcir la planche, la pour  rit, c'est-à-dire diminue encore sa résistance,  ce qui s'explique par le fait que le plâtre de      la planche ne peut pas s'hydrater normale  ment parce qu'il est à l'abri de l'air.  



  L'expérience a montré que le procédé     sus-          décrit    remédie à ces deux inconvénients. En  effet, grâce à la colle dissoute dans l'eau, la  prise du plâtre se fait lentement même lors  qu'il y a excès de liquide. On a donc tout le  temps de mouler la planche tout en lui don  nant sa dureté maximum et cette dureté est  telle qu'il est inutile, la planche une fois  posée, de la recouvrir d'une nouvelle couche  de plâtre; on peut la badigeonner immédia  tement.  



  De préférence, on emploiera de la colle  forte dans la proportion, par exemple, de  150 gr de colle pour<B>50</B> litres d'eau. De pré  férence aussi, les planches auront la forme  montrée au dessin, c'est-à-dire que l'un de  leurs grands bords se terminera par une arête       c,    tandis que l'autre grand bord présentera  deux arêtes di     d2    entre lesquelles une gorge  e à section triangulaire se trouve réservée.  Lors de la pose, deux planches adjacentes  seront montées, comme dessiné en     fig.    1,  l'arête c de l'une de ces planches pénétrant  dans la gorge e de l'autre; cette gorge a été  au préalable remplie de plâtre     qui,    lors de la  pénétration de l'arête, sort en partie et forme  un joint f.  



  On pourrait employer autre chose que des  roseaux comme armature, par exemple des  scories, et on pourrait donner à l'élément de  construction une autre forme que celle d'une  planche, par exemple celle d'une brique. Les  éléments en forme de planche s'emploieront  avec avantage pour les plafonds et ceux en  forme de brique pour les galandages. Bien  entendu le joint pourrait être différent de  celui représenté en     fig.    1 ; pour les planches  en particulier, on pourra employer le joint en  escalier montré en     fig.    3, et pour les briques  le joint en rainure et en saillie semi-circu  laires montré en     fig.    4.



  A method of manufacturing a plaster construction element, and a plaster construction element obtained by this process. The present invention relates to a method of manufacturing a plaster building element as well as to a plaster building element obtained by this process.



  This process is characterized in that one pours, around a frame, plaster mixed with water in which glue has been dissolved, the whole in order to obtain an element sufficiently resistant to withstand transport without deterioration and to be used in the making of ceilings and partitions without it being necessary to cover it, after its installation, with a new layer of plaster.



  This process can be implemented, for example in the following way: In the bottom of a mold, there is a layer of plaster mixed with water in which glue has been dissolved beforehand, then it is placed on this layer a row of reeds forming an armature which is covered with a new layer of plaster also mixed with water in which glue has been dissolved, then the whole is left to dry. It is thus possible to obtain an element in the form of a board as shown at cc in FIGS. 1 and 2, in cross section and in plan <B>; </B> b are the reeds.



  In order for the plaster to harden sufficiently, it is known that it is necessary to mix it with sufficient water, but then, the setting is done so quickly that very often the plaster hardens before having had the time to introduce it into the mold; it is for this reason that, in the present manufacture of reed boards, used in construction, the plaster is mixed with a minimum of water. There is thus all the time necessary for the molding of the plaster, but the board, once dry, is not strong enough, almost always it deteriorates during transport; in addition, after installation, it must be covered with a layer of plaster which has been mixed with enough water to make it hard.

   But this water absorbed in this way, instead of hardening the board, puts it off, that is to say further reduces its resistance, which is explained by the fact that the plaster of the board cannot hydrate. normally because it is shielded from the air.



  Experience has shown that the above-described process overcomes these two drawbacks. Indeed, thanks to the glue dissolved in water, the plaster setting is done slowly even when there is excess liquid. There is therefore plenty of time to mold the board while giving it its maximum hardness and this hardness is such that it is useless, once the board has been installed, to cover it with a new layer of plaster; it can be brushed immediately.



  Preferably, strong glue will be used in the proportion, for example, of 150 g of glue to <B> 50 </B> liters of water. Also preferably, the boards will have the shape shown in the drawing, that is to say that one of their large edges will end with an edge c, while the other large edge will have two edges di d2 between which a throat with a triangular section is reserved. When laying, two adjacent boards will be mounted, as drawn in fig. 1, the edge c of one of these boards penetrating into the throat e of the other; this groove has been filled beforehand with plaster which, when the ridge penetrates, partially comes out and forms a seal f.



  One could use something other than reeds as reinforcement, for example slag, and one could give the building element a shape other than that of a plank, for example that of a brick. Plank-shaped elements will work with advantage for ceilings and brick-shaped ones for wall partitions. Of course, the seal could be different from that shown in FIG. 1; for planks in particular, the staircase joint shown in fig. 3, and for bricks the semi-circular groove and protrusion joint shown in fig. 4.
