Description
<Desc/Clms Page number 1>
-Le hourdis est constitué d'élément en béton armé de composition courante et préfabriqués en usine.
Le profil est trapézoidal de bases'.! 3IOmm et 333mmo
La hauteur "h" est variable suivant les surcharges à supporter et les portées à franchir. En principe "h" varie de 8 à 15cm. la longueur "L" des éléments varie généralement de 2 m à 5,50m.
Ces éléments sont allégés par des vides de forme cylindrique
EMI1.1
"b", dont le nombre et le diamètre varient suivant la hauteùrit'''..réalisée.
Le diamètre varie en principe de 4 à 8 cm.
L'élément comporte le long des parois latérales et en principe tous les 75cm des encoches de forme et de dimensions renseignées aux plans.
Le but de ces encoches est de permettre et de faciliter l'accès de l'arma- ture "e" prévue dans le joint des éléments et d'en assurer le placement ai- sé.
L'armature constituée de fers ronds en acier comporte : I ) des barres de tension longitudinales "c" dont le nombre et les diamètres

.,;r:(=1:$en:=onction du calcul.
2 ) des barres transversales de répartition " d " de 5 ou 6 mm de diamètre, soudées ou ligaturées aux précédentes et disposées en principe tous les
35 cm. Elles sont profilées comme indiqué aux plans. Elles sont munies de crochets pour recevoir une barre' de 6,8 ou 10 mm " e " qui assure la liaison entre les éléments.
Après pose jointive des éléments., et après avoir au préalable glissé et fixé l'armature "e", les vides triangulaires et circulaires "a" laissés entre deux éléments consécutifs, ainsi que les encoches précitée sont remplis d'un béton pour béton armé de composition bien définie, de façon à remplir parfaitement le vide et bien enrober l'armature.
La partie circulaire du joint n'est pas nécessairement du mène diamètre que celui des vides cylindriques intérieurs de l'élément.
Caractères distinctifs.
1 ) Présence d'une armature transversale liaisonnée d'élément à élément et qui constitue chainage réalisant ainsi une meilleure tenue contre les fissurations.
2 ) La forme du joint entre deux éléments et son remplissage se coulant facilement, réalisent un excellent accrochage, une meilleure soli- darité des éléments entre eux ainsi que de l'ensemble du hourdis. Solida- rité augmentée par la présence de l'armature transversale.
3 ) Dans les cas courants d'exécution de hourdis , il n'y a plus nécessité de jointoyer la partie inférieure du hourdis avant de couler les joints. Ce qui constitue un grand avantage.
4 ) Manutention et pose rendues plus faciles et aisées grâce à la présence des crochets d'extrémités de l'armature transversale.Il en est de même par la forme du joint.

-The slab is made of reinforced concrete elements of current composition and prefabricated in the factory.
The base profile is trapezoidal.! 3IOmm and 333mmo
The height "h" is variable according to the overloads to be supported and the spans to be crossed. In principle "h" varies from 8 to 15cm. the length "L" of the elements generally varies from 2 m to 5.50 m.
These elements are lightened by cylindrical voids
EMI1.1
"b", the number and diameter of which vary according to the height "" ... achieved.
The diameter varies in principle from 4 to 8 cm.
The element comprises along the side walls and in principle every 75cm notches of shape and dimensions indicated in the plans.
The purpose of these notches is to allow and facilitate access to the reinforcement "e" provided in the joint of the elements and to ensure easy placement.
The reinforcement made up of steel round bars comprises: I) longitudinal tension bars "c", the number and diameters of which
EMI1.2
.,; r: (= 1: $ en: = anointing of the calculation.
2) crossbars of distribution "d" of 5 or 6 mm in diameter, welded or tied to the previous ones and arranged in principle every
35 cm. They are profiled as indicated on the plans. They are provided with hooks to receive a bar 'of 6.8 or 10 mm "e" which ensures the connection between the elements.
After joint installation of the elements., And after having previously slipped and fixed the reinforcement "e", the triangular and circular voids "a" left between two consecutive elements, as well as the aforementioned notches are filled with a concrete for reinforced concrete of well-defined composition, so as to fill the void perfectly and coat the framework well.
The circular part of the seal is not necessarily of the same diameter as that of the internal cylindrical voids of the element.
Distinctive characters.
1) Presence of a transverse reinforcement linked from element to element and which constitutes chaining thus achieving better resistance against cracking.
2) The shape of the joint between two elements and its easily flowing filling, achieve excellent bonding, better solidarity of the elements between them and of the whole of the slab. Strength increased by the presence of the transverse reinforcement.
3) In common cases of slab construction, there is no longer any need to grout the lower part of the slab before pouring the joints. Which is a great advantage.
4) Handling and installation made easier and easier thanks to the presence of the end hooks of the transverse reinforcement. The same is true of the shape of the joint.
