Description

La présente invention concerne le domaine de la construction et plus particulièrement les moyens destinés à réaliser des planchers dans un immeuble ou une maison individuelle.The present invention relates to the field of construction and more particularly the means for making floors in a building or a house.

ARRIERE PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

Une technique bien connue de réalisation de planchers consiste à disposer entre deux murs en regard des poutrelles préfabriquées, à combler l'espace entre les poutrelles par des entrevous ou hourdis, à placer une armature au-dessus des entrevous, armature qui vient coopérer avec une armature de chaînage qui court sur l'arase des murs sur lesquels reposent les poutrelles et à couler une dalle de compression sur les entrevous qui noie les armature de plancher et de chaînage dans une même matrice de béton.A well-known technique of making floors consists of placing between two walls facing prefabricated beams, to fill the space between the beams by interjoists or slabs, to place a frame above interjoists, frame that comes to cooperate with a Chaining reinforcement that runs on the arase of the walls on which the beams rest and to cast a compression slab on the interjoists which drowns the reinforcement of floor and chaining in the same matrix of concrete.

Les questions d'ordre environnemental sont devenues prépondérantes notamment en matière d'économie d'énergie. Elles se traduisent dans le domaine du bâtiment, par des solutions d'isolation des volumes intérieurs des bâtiments. Il existe deux manières de traiter l'isolation, soit en enfermant l'ensemble de la construction dans une enveloppe isolante, soit en pratiquant une isolation à l'intérieur d'un mur ou d'une cloison dont une face est au contact avec l'atmosphère extérieure.Environmental issues have become paramount, particularly in terms of energy saving. They are translated in the field of building, by solutions of insulation of the interior volumes of the buildings. There are two ways to treat the insulation, either by enclosing the entire construction in an insulating envelope, or by insulating inside a wall or partition with one side in contact with the insulation. outside atmosphere.

Dans le cas du traitement de l'isolation par l'intérieur, l'un des principaux problèmes à résoudre est celui posé par les ponts thermiques, c'est-à-dire celui du chemin de conduction de la chaleur ou du froid par la continuité d'un matériau conducteur de calorie depuis l'extérieur du bâtiment jusqu'à l'intérieur. C'est notamment le cas des planchers réalisés comme rappelé ci-dessus.In the case of interior insulation treatment, one of the main problems to be solved is that posed by the thermal bridges, that is to say that of the path of conduction of heat or cold by the continuity of a calorie-conducting material from the outside of the building to the interior. This is particularly the case of floors made as recalled above.

En ce qui concerne ces planchers, on a proposé des rupteurs de pont thermique comme par exemple décrits dans le document FR 2 830 553 . Ces rupteurs de pont thermique sont souvent associés à des entrevous isolants comme ceux faisant l'objet du document FR 2 829 780 . Ces entrevous présentent la particularité de posséder une languette inférieure qui vient masquer la face inférieure des talons des poutrelles pour constituer une barrière isolante entre la face inférieure du plancher et l'atmosphère extérieure que constitue un vide sanitaire. Ces languettes et donc les entrevous ont une tendance à devenir de plus en plus épaisses pour l'obtention d'une isolation de plus en plus performante. En outre, les entrevous de ce type sont taillés, au niveau des languettes, de manière précise pour assurer une continuité dans la couche isolante sous plancher.With regard to these floors, it has been proposed thermal bridge breakers as for example described in the document FR 2,830,553 . These thermal breakers are often associated with insulating interjoists such as those covered by the document FR 2 829 780 . These interjoists have the particularity of having a lower tongue that masks the underside of the heels of the beams to form an insulating barrier between the underside of the floor and the outside atmosphere that is a crawl space. These tongues and therefore the interjoists have a tendency to become more and more thick for obtaining a more and more efficient insulation. In addition, interjoists of this type are cut, at the tabs, precisely to ensure continuity in the insulating layer under floor.

On rappellera que l'écartement entre deux poutrelles est standard de l'ordre de 60 centimètres. Cependant, peu nombreux sont les bâtiments qui sont divisibles par ce module. Il existe donc pratiquement toujours une dernière travée, entre un mur longitudinal et la dernière poutrelle qui est de largeur inférieure à 60 centimètres.It will be recalled that the spacing between two beams is standard of the order of 60 centimeters. However, not many buildings are divisible by this module. There is almost always a last span between a longitudinal wall and the last beam that is less than 60 centimeters wide.

Dans la pratique, la pose des poutrelles pour la réalisation d'un plancher de ce type commence par une poutrelle le long d'un mur longitudinal avec la mise en place de rupteurs de pont thermique longitudinaux entre les deux puis la mise en place des poutrelles suivantes, au pas ou module de 60 centimètres avec dépose d'entrevous standard et de rupteurs thermiques transversaux et, enfin, entre la dernière poutrelle et le second mur longitudinal, la pose d'entrevous spéciaux retaillés dans des entrevous standard pour être ajustés à la largeur résiduelle « démodulée » de la dernière travée. Cette retaille est laissée à l'initiative du poseur qui la réalise avec les moyens de chantier c'est-à-dire de manière très approximative.In practice, laying beams for the realization of a floor of this type begins with a beam along a longitudinal wall with the establishment of longitudinal thermal bridge breakers between the two and the establishment of joists following, in step or module of 60 centimeters with removal of standard interjoists and transverse thermal breakers and, finally, between the last beam and the second longitudinal wall, the installation of special interjoists re-cut in standard interjoists to be adjusted to the residual width "demodulated" of the last span. This scrap is left to the initiative of the installer who realizes it with the means of construction that is to say in a very approximate way.

Une autre manière de procéder réside dans la pose de la dernière poutrelle à la bonne distance par rapport à mur longitudinal de manière à loger entre cette poutrelle et le mur un rupteur longitudinal, l'avant-dernière travée étant celle qui n'est pas à la largeur standard.Another way of proceeding resides in the installation of the last beam at the right distance with respect to longitudinal wall so as to accommodate between this beam and the wall a longitudinal breaker, the penultimate bay being the one which is not the standard width.

Par l'invention, on se propose de fournir au poseur les moyens de procéder de manière simple à cet ajustement sur chantier.By the invention, it is proposed to provide the installer the means to proceed in a simple way to this adjustment on site.

L'art antérieur est encore illustré par le document EP-A-0 014 294 .The prior art is further illustrated by the document EP-A-0 014 294 .

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

C'est ainsi que l'invention a pour objet un entrevous modulable constitué d'au moins deux parties dont chacune comporte un bord longitudinal extérieur avec un profil transversal en correspondance de forme avec le profil des éléments du plancher en attente de part et d'autre de l'entrevous modulable et un bord longitudinal intérieur pourvu de reliefs mâles et femelles d'emboîtement démontable, la partie pourvue de reliefs femelles étant de dimension transversale réglable par découpe longitudinale, les reliefs femelles étant toujours présents malgré la découpe.Thus, the invention relates to a modular intervous consisting of at least two parts each of which has an outer longitudinal edge with a transverse profile in correspondence of shape with the profile of the elements of the floor waiting for share and Another of the adjustable interjoists and an inner longitudinal edge provided with removable male and female interlockings, the portion provided with female reliefs being of transverse dimension adjustable by longitudinal cut, the female reliefs being always present despite the cutting.

L'ajustement possible de la dimension transversale de l'entrevous par une découpe simple, supprime le travail du poseur consistant à reproduire le profil de l'entrevous sur l'un de ses côtés, travail qui demande une grande habileté qui n'est pas toujours présente sur les chantiers. Un ajustement imprécis conduit à une mauvaise qualité de l'isolation thermique réalisée.The possible adjustment of the transverse dimension of the interjoists by a simple cut, removes the work of the installer to reproduce the profile of the interjoists on one of its sides, work that requires a great skill that is not always present on construction sites. An imprecise adjustment leads to poor quality of the thermal insulation performed.

L'entrevous de l'invention garde ses deux profils d'extrémités transversales tels qu'il résultent de la fabrication en usine, avec leur aptitude à coopérer de manière précise avec les profils correspondants des entrevous adjacents lors de la réalisation du plancher.The interjoists of the invention retain its two transverse end profiles as they result from factory manufacture, with their ability to cooperate precisely with the corresponding profiles of adjacent interjoists during the production of the floor.

Selon l'invention, les reliefs d'assemblage sont prévus pour pénétrer les uns dans les autres de manière à conserve une résistance à l'entrevous suffisante pour d'une part, soutenir sans danger le poids d'un ouvrier et, d'autre part, pour soutenir le poids de béton qui forme la dalle de compression.According to the invention, the assembly reliefs are designed to penetrate one into the other so as to maintain a sufficient interstitial resistance to, on the one hand, safely support the weight of a worker and, on the other hand, on the other hand, to support the concrete weight that forms the compression slab.

Les reliefs femelles sont des évidements dont la longueur est suffisamment importante pour qu'ils ne disparaissent pas avec la chute lors de la découpe de la partie d'entrevous qui les porte.The female reliefs are recesses whose length is large enough so that they do not disappear with the fall when cutting the part of interstices who wears them.

Dans le mode de réalisation d'application la plus universelle, les deux bords longitudinaux de l'entrevous de l'invention ont un profil symétrique l'un de l'autre par rapport à un plan vertical longitudinal. Cet entrevous se place donc comme une clé entre deux extrémités biseautées symétriques de languettes isolantes d'un entrevous et d'un rupteur longitudinal.In the most universal application embodiment, the two longitudinal edges of the interjoists of the invention have a profile symmetrical to each other with respect to a longitudinal vertical plane. This intervous is therefore a key between two beveled symmetrical ends of insulating tongues of a interjoists and a longitudinal breaker.

Dans une deuxième variante de ce mode de réalisation, l'entrevous possède sur chacun de ses bords longitudinaux un moyen d'assemblage par emboîtement d'une languette d'isolation rapportée. Ce moyen peut par exemple être une queue d'aronde femelle pouvant recevoir une queue d'aronde mâle portée par la languette à rapporter.In a second variant of this embodiment, the interjoists has on each of its longitudinal edges means for assembly by interlocking an insulation tab reported. This means may for example be a female dovetail that can receive a male dovetail carried by the tongue to report.

Enfin, dans tous les entrevous de l'invention, l'épaisseur peut également être ajustée en fonction des différentes épaisseurs de languette que l'on rencontre sur le marché.Finally, in all the interjoists of the invention, the thickness can also be adjusted according to the different thicknesses of tongue that are encountered on the market.

D'autres caractéristiques et avantages de l'invention ressortiront de la description donnée ci-après d'un exemple de réalisation de l'invention.Other features and advantages of the invention will emerge from the description given below of an exemplary embodiment of the invention.

  • la figure 3 illustre par une coupe transversale les deux parties d'un entrevous conforme à l'invention,

Reference will be made to the appended drawings among which:
  • the Figures 1A, 1B and 2 illustrate the provisions of interviews that you meet on site,
  • the figure 3 illustrates by a cross section the two parts of a interjoists according to the invention,
  • the figure 4 illustrates in the same way an alternative embodiment of the interjoists of the figure 3 .

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

Aux figures 1A, 1B et 2, on a représenté deux murs longitudinaux 1 et 2 parallèlement auxquels des poutrelles à talon 3,4,5,6,7,8 et 9 s'étendent en prenant appui par leurs extrémités sur des murs transversaux non représentés, dont l'arase est au niveau de l'arase des murs 1 et 2. Ces murs 1 et 2 et les poutrelles définissent la direction longitudinale du plancher et de ses constituants.To the Figures 1A, 1B and 2 two longitudinal walls 1 and 2 are shown parallel to which beams with heel 3,4,5,6,7,8 and 9 extend while being supported by their ends on unrepresented transverse walls, whose arase is at the level of the arase walls 1 and 2. These walls 1 and 2 and the beams define the longitudinal direction of the floor and its components.

La figure 1A illustre un premier entrevous 10 qui prend appui sur le mur 1 et sur une poutrelle 3, avec une languette 11 glissée sous le talon de la poutrelle 3. La dimension transversale de l'entrevous LS est standard, correspondant à l'écartement habituel de par exemple 60 centimètres qui sépare deux poutrelles consécutives ou un premier mur longitudinal et une première poutrelle.The Figure 1A illustrates a first interjoists 10 which is supported on the wall 1 and on a beam 3, with a tongue 11 slid under the heel of the beam 3. The transverse dimension of the interlocks LS is standard, corresponding to the usual spacing of by example 60 centimeters separating two consecutive beams or a first longitudinal wall and a first beam.

A l'autre extrémité transversale du plancher, figure 1B, on trouve une poutrelle 4 dont le talon supporte un entrevous standard 12 avec une languette 13 sous la poutrelle 4 et un entrevous 14 qui prend appui sur le mur 2 par une découpe 15 faite sur chantier. En effet la distance LV qui sépare la poutrelle 4 du mur 2 n'est pas égale à la distance LS. Même si elle avait été de cette valeur, il aurait fallu retailler l'entrevous pour en faire sauter la languette.At the other end of the floor, Figure 1B , there is a beam 4 whose heel supports a standard interjoists 12 with a tongue 13 under the beam 4 and an interjoists 14 which bears on the wall 2 by a cutout 15 made on site. Indeed the distance LV between the beam 4 of the wall 2 is not equal to the distance LS. Even if it had been of this value, it would have been necessary to resize the interjoists to make blow the tongue.

A la figure 2, on a illustré une technique dans laquelle le plancher P comporte des rupteurs de pont thermique longitudinaux 16 et 17. Ces rupteurs comportent également des languettes d'isolation 18 et 19 sous les poutrelles 5 et 9. Les entrevous 20, 21 et 22 sont des entrevous standard qui ne conviennent pas pour la travée entre les deux poutrelles 8 et 9 dont l'écartement LV n'est pas standard.To the figure 2 a technique has been illustrated in which the floor P has longitudinal thermal bridge switches 16 and 17. These breakers also comprise isolation tabs 18 and 19 under the beams 5 and 9. The interjoists 20, 21 and 22 are standard interjoists which are not suitable for the span between the two beams 8 and 9 whose LV gap is not standard.

C'est à cet endroit, comme à la place de l'entrevous 14 de la figure 1B, que l'entrevous modulable selon l'invention trouve sa place.This is where, as in the place of the interstage 14 of the Figure 1B , that intervous modular according to the invention finds its place.

La figure 3 illustre un premier mode de réalisation de cet entrevous 30. Celui-ci est constitué d'au moins deux parties 31 et 32 dont chacune comporte un bord longitudinal extérieur 31a et 32a avec un profil transversal en correspondance de forme avec le profil des éléments du plancher en attente de part et d'autre de l'entrevous modulable (voir par exemple la figure 2). Dans le cas d'espèce, le profil transversal du bord 31a est symétrique, par rapport à un plan vertical longitudinal de l'entrevous, du profil transversal du bord 32a. L'entrevous comporte également un bord longitudinal intérieur 31b et 32b pourvu de reliefs mâles 33 (tenons) et femelles 34 d'emboîtement démontable, la partie 32 pourvue de reliefs femelles 34 étant de dimension transversale réglable par découpe longitudinale, les reliefs femelles (évidements) étant suffisamment profond pour qu'ils subsistent malgré la découpe et qu'ils puissent encore recevoir le totalité des tenons 33. Cette découpe est marquée par le trait pointillé 35. La section des reliefs 33 ou des évidements 34 est de toute nature (circulaire, rectangulaire, polygonale,...) apte à ce que l'emboîtement soit résistant à un effort de flexion résultant d'une charge appliquée sur la partie supérieure de l'entrevous.The figure 3 illustrates a first embodiment of this interjoists 30. This consists of at least two parts 31 and 32, each of which has an outer longitudinal edge 31a and 32a with a transverse profile in correspondence of shape with the profile of the floor elements waiting on both sides of the modular interjoists (see for example the figure 2 ). In the case in point, the transverse profile of the edge 31a is symmetrical, with respect to a longitudinal vertical plane of the interjoists, of the transverse profile of the edge 32a. The interjoists also comprises an inner longitudinal edge 31b and 32b provided with male 33 (tenons) and female 34 removable interlocking protrusions, the portion 32 provided with female reliefs 34 being of transverse dimension adjustable by longitudinal cut, the female reliefs (recesses ) being deep enough so that they remain despite the cutting and they can still receive all the pins 33. This cut is marked by the dotted line 35. The section of the reliefs 33 or recesses 34 is of any kind (circular , rectangular, polygonal, ...) adapted so that the interlock is resistant to a bending force resulting from a load applied to the upper part of the interjoists.

L'épaisseur e de la partie inférieure de l'entrevous est également réglable par découpe horizontale de la partie inférieure de l'entrevous.The thickness e of the lower part of the interjoists is also adjustable by horizontal cutting of the lower part of the interjoists.

Le poseur procède à la mesure de la dimension LV telle qu'elle est définie aux figures 1B et 2. Il en déduit la valeur de la coupe qu'il doit effectuer sur la partie 32 de l'entrevous.The installer proceeds to measure the LV dimension as defined in Figures 1B and 2 . He deduces the value of the cut that he must make on the part 32 of the interjoists.

L'entrevous final alors réalisé après la coupe permet d'une part d'assurer un bon soutien de l'entrevous par les talons des poutrelles et, d'autre par, de combler parfaitement le vide dépourvu de matériau isolant en continuité avec les languettes et d'un entrevous (22 sur la figure 2) adjacent et un rupteur longitudinal (17 de la figure 2).The interjoists final then realized after the cutting allows on the one hand to ensure a good support of intervous by the heels of the beams and, on the other hand, to perfectly fill the vacuum devoid of insulating material in continuity with the tabs and an interjoists (22 on the figure 2 ) and a longitudinal switch (17 of the figure 2 ).

Dans un cas d'application où le rupteur 17 est dépourvu de languette, comme cela existe, un peut être avantageux de prévoir sur le rupteur selon l'invention un moyen 36, 37 en attente de fixation d'une languette rapportée telle que celle 38 dans l'ouverture en queue d'aronde 37 de la figure 4.In an application case where the switch 17 does not have a tab, as it exists, it may be advantageous to provide on the switch according to the invention a means 36, 37 waiting for attachment of a tongue attached. such as that 38 in the dovetail opening 37 of the figure 4 .

A cet effet, la languette 38 possèdera une queue d'aronde mâle 39 pour coopérer avec l'une ou l'autre des queue d'aronde 36,37 représentées sur la partie 32.For this purpose, the tongue 38 will have a male dovetail 39 to cooperate with one or the other of the dovetail 36,37 represented on the part 32.

Avec les dispositions de l'invention, aucun ajustement ne dépend plus de la dextérité du poseur, celui n'ayant plus à faire que des coupes droites qui peuvent être prémarquées sur le produit. La figure 4 illustre aussi la partie inférieure 40 de l'entrevous qui a été découpée pour ajuster la couche isolante en plafond de vide sanitaire par exemple.With the provisions of the invention, no adjustment no longer depends on the dexterity of the installer, the one having to do only straight cuts that can be premarked on the product. The figure 4 also illustrates the lower part 40 of the interjoists which has been cut to adjust the insulating layer ceiling crawl space for example.
