Le profilé longitudinal 2 est constitué, selon The longitudinal profile 2 is formed, according to

Le profilé longitudinal 2 peut également être constitué, conformément à une variante de réalisation de l'invention, en une matière synthétique extrudée rigide The longitudinal profile 2 can also be made, in accordance with an alternative embodiment of the invention, of a rigid extruded synthetic material

L'invention a également pour objet un dispositif The invention also relates to a device

lièrement aux figures 2 et 3 et essentiellement constitué par une machine 3 de moulage en continu ou en discontinu, dont le moule 4 est muni à son extrémité arrière d'au moins une ouverture étanche 5 d'introduction d'au moins un profilé longitudinal 2, par un moyen 6 d'introduction du ou des profilés 2 dans le moule 4 et, éventuellement, par in FIGS. 2 and 3 and essentially constituted by a machine 3 for continuous or discontinuous molding, the mold 4 of which is provided at its rear end with at least one sealed opening 5 for introducing at least one longitudinal profile 2 , by means 6 for introducing the profile (s) 2 into the mold 4 and, optionally, by

Le moyen 6 d'introduction du ou des profilés 2 dans le moule 4 se présente avantageusement sous forme d'un chariot mobile 8 monté de manière coulissante, en sens longitudinal, sur le bâti de la machine de moulage 3 The means 6 for introducing the profile (s) 2 into the mold 4 is advantageously in the form of a movable carriage 8 slidably mounted, in longitudinal direction, on the frame of the molding machine 3

Ainsi, au début du moulage de chaque hourdis un profilé 2 est placé dans le logement correspondant de la traverse 10 du moyen 6 ou est serré dans la pince 11 correspondante, puis poussé dans le moule d'une longueur correspondant à un cycle de moulage Après expansion de la mousse, le tronçon moulé est poussé hors du moule du côté opposé au moyen 6, qui pousse simultanément le ou les profilés de rigidification dans le moule d'une longueur correspondant au nouveau tronçon à mouler Ces opérations sont répétées jusqu'à obtention de la longueur de hourdis désirée, les profilés 2 présentant, dans un tel cas, une longueur égale à celle des hourdis à obtenir Il est également possible, en particulier dans le cas d'utilisation de pinces 11, de réaliser un moulage en continu d'un hourdis unique, ce dernier étant débité à des longueurs désirées de hourdis individuels à la sortie de la machine de moulage 3, lors d'un cycle de moulage, par l'intermédiaire d'une unité de Thus, at the start of the molding of each slab, a profile 2 is placed in the corresponding housing of the cross member 10 of the means 6 or is clamped in the corresponding clamp 11, then pushed into the mold of a length corresponding to a molding cycle After foam expansion, the molded section is pushed out of the mold on the opposite side by means 6, which simultaneously pushes the stiffening profile (s) in the mold of a length corresponding to the new section to be molded These operations are repeated until obtained of the desired length of slabs, the profiles 2 having, in such a case, a length equal to that of the slabs to be obtained It is also possible, in particular in the case of the use of pliers 11, to carry out a continuous molding d '' a single slab, the latter being cut to desired lengths of individual slabs at the outlet of the molding machine 3, during a molding cycle, via a unit of

Le dispositif 7 de réalisation en continu de profilés 2 peut se présenter, avantageusement, sous forme, soit d'une plieuse de tôle en continu ou en discontinu, soit d'une presse à injecter Dans le premier cas, la plieuse de tôle peut être alimentée en continu par une fine bande de tôle et réaliser un pliage en continu de cette bande ou encore être alimentée par des sections de bandes de tôle correspondant à une longueur prédéterminée The device 7 for continuously producing profiles 2 can advantageously be in the form of either a continuous or discontinuous sheet bending machine or an injection molding machine. In the first case, the sheet bending machine can be continuously fed by a thin strip of sheet metal and continuously bend this strip or even be fed by sections of sheet strips corresponding to a predetermined length

Le ou les profilés longitudinaux 2 intégrés dans la masse des hourdis 1 peuvent présenter une très faible épaisseur, qui, en pratique, n'est pas compatible avec une tenue au flambage desdits profilés 2 suivant leur section The invention also relates to the slabs thus obtained which are characterized in that they are provided with at least one longitudinal section 2 integrated in their mass. The longitudinal section (s) 2 integrated in the mass of the slabs 1 may have a very small thickness, which, in practice, is not compatible with a buckling behavior of said sections 2 according to their section
