  HOURDIS A NERVURES PRECOULEES DANS DES CLAVAUX ISOLANTS EN BETON
OU EN TERRE CUITE. 



  DESCRIPTION : 
10/ Le Hourdis se compose de clavaux vibrés en béton caver- neux ou en béton lourd ou en terre cuite. 



   2 / Le Hourdis réalise une surface plane à la partie supé- rieure. 



   3 / Le Hourdis réalise une surface plane à la partie infé- rieure. 



   40/ Les clavaux de par leur forme, lorsqu'ils sont mis bout à bout, constituent une rainure centrale dans laquelle la poutre est coulée et.éventuellement vibrée à   1-'aiguille.   Les fers peuvent avoir la longueur de   Isolément   ou être dépassantso 
5 / Cette combinaison de la poutre et des clavaux réali- sée soit sur chantier, soit à l'usure donne un élément complet du hour- dis. 



   6 / Cet élément présente à la surface inférieure une sur- face plane constituée   d'une   matière uniforme, prête à recevoir direc- tement le plafonage, évitant ainsi le fendillement ou des tons diffé- rents au séchage. 



   70/ Les éléments se posent   l'un   à côté   de, l'autre   portant à chaque bout de 0.10 cm. sur leurs appuis. 



   80/ Lorsque le plancher est entièrement posé, dans la join- ture de chaque élémentil est coulé un lait de ciment qui forme à la prise un coin en forme d'aiguille, ayant à la partie supérieure une pro- éminence sur laquelle viennent s'appuyer de haut en bas et sur toute leur longueur, les deux éléments voisins,empêchant tout fléchissement   d'un   élément par rapport à l'autre.

   9 / Lorsque le verrrouillage est terminé, il est répandu sur la totale supérieure du plancher une légère barbotine étendue à la brosse, 
10 / Le Hourdis posé comme il est dit ci-dessus ne nécessite aucun apport de matière quelconque pour la finition. La pose se fait sans étançonnage ni échafaudage. 



   11 / Les éléments en terre cuite (figure 2) sont fabriqués en deux pièces qui peuvent éventuellement être écartées au moyen d'une plaque (C) afin d'obtenir un volume de poutre supérieur permettant de plus longues portées.

  PRECAST RIBBED HOUSINGS IN CONCRETE INSULATING SLABS
OR IN TERRACOTTA.



  DESCRIPTION:
10 / The Hourdis is made up of vibrating clavals in cavernous concrete or heavy concrete or terracotta.



   2 / The Hourdis creates a flat surface at the top.



   3 / The Hourdis creates a flat surface at the bottom.



   40 / The clavaux by their shape, when placed end to end, constitute a central groove in which the beam is cast and possibly vibrated at 1-'aiguille. Irons may be the length of Single or protruding o
5 / This combination of the beam and the keystones produced either on site or due to wear gives a complete element of the slab.



   6 / This element has on the lower surface a flat surface made of a uniform material, ready to receive the ceiling directly, thus avoiding cracking or different tones on drying.



   70 / The elements are posed one beside, the other carrying at each end of 0.10 cm. on their supports.



   80 / When the floor is completely laid, in the joint of each element there is poured a cement milk which forms a needle-shaped wedge at the grip, having at the top a prominence on which come s' press from top to bottom and along their entire length, the two neighboring elements, preventing any sagging of one element in relation to the other.

   9 / When the locking is finished, a light slip spread with a brush is spread over the entire upper floor of the floor,
10 / The Hourdis laid as it is said above does not require any input of any material for the finish. The installation is done without shoring or scaffolding.



   11 / The terracotta elements (figure 2) are made in two pieces which can optionally be separated by means of a plate (C) in order to obtain a higher beam volume allowing longer spans.

Claims

ABSTRACT.

------------ PRECOLD RIBBED HOUSING IN INSULATING CONCRETE OR TERRE CUITE is a novelty because of: 10 / That the clavals placed end to end operate independently of the beam that connects them, like arches and work on compression, thus removing the irons necessary for compression up to the span of 4 meters, fifty centimeters .. (4.50 meters).

20 / The cut of a trapezoidal shape of the cast beam means that when the grip of this beam is completed, the clavals remain suspended from it by wedging from top to bottom.

30 / The sides of the clavau are crossed by a groove (A) receiving an iron working in compression for the spans exceeding 4.50 meters. This iron is housed in the bottom of the groove, the upper part (B) remaining free. It is this free part which will be based on the cement milk which will be poured between the two neighboring elements thus forming locking and wedging.

40 / The irons are all embedded in rich concrete and are not in contact with concrete cavernous, ashy or other, thus avoiding any chemical reactions on the iron.

5 / The concrete rib being embedded in the qlavau, is not visible at the lower part and is thus completely isolated from the lower floor.

The sleekness of the clavals thus increases thermal and acoustic insulation while reducing weight to a minimum.

60 / the possibility of manufacturing the elements on site or in the factory.

70 / For terracotta clavals, grooves can be provided in the sheath of the beam and on the outer sides of the clavau allowing better adhesion of the concrete beam or of the cast needle after installation.

80 / the possibility of modifying the thickness of the beam when using terracotta clavaux.

90 / the possibility for slabs made by means of clavaux. terracotta to receive a joist at the upper part to fix the floors or parquet floors (axis in axis 33 centimeters) as well as a piece of wood at the lower part to attach ceiling panels.
