Description
FIXATION DIRECTE SUR PARPAINGS OU BRIQUES CREUSES L'invention se rattache au secteur technique des dispositions et moyens de fixation sur des éléments de parois, murs, cloisons réalisés à partir de parpaings ou de briques creuses. The invention relates to the technical sector of arrangements and means of attachment to wall elements, walls, partitions made from blocks or hollow bricks.
Ces parpaings ou briques creuses sont réalisés à partir d'ensemble monobloc alvéolaires avec deux parois d'extrémité et souvent une paroi intermédiaire en définissant ainsi des alvéoles contribuant à rendre plus légers ces produits. These blocks or hollow bricks are made from monobloc alveolar assembly with two end walls and often an intermediate wall thus defining the cells helping to make these products lighter.
Généralement, on est amené à faire plaquer contre le mur ou la paroi ainsi réalisés par l'assemblage et montage de plusieurs parpaings ou briques, des panneaux complémentaires formant isolation réalisés notamment en polystyrène ou matériau équivalent. Pour assurer le plaquage et la tenue des panneaux précités contre les murs de briques ou de parpaings, on utilise des fixations directes qui comprennent une cheville d'ancrage de grande longueur réalisée en matière plastique, et susceptible de recevoir intérieurement un élément de vissage permettant l'expansion de l'extrémité de la cheville. On a ainsi représenté à la figure 1 la mise en oeuvre d'une telle fixation. La cheville (1) d'ancrage comprend d'une manière connue sur une partie de sa longueur une fente (la) longitudinale définissant deux lèvres (lb) semi-cylindriques et maintenues entre elles par une pluralité de points de saillies (1c) détachables lors de l'introduction de l'élément de vissage. La cheville présente dans la zone des lèvres des languettes (1 d) débordant en saillie et qui viennent s'ancrer dans la ou les parois correspondantes traversées du parpaing ou brique. Le fût <B>(If)</B> de la cheville défini entre la tête<B>(l</B>e) et les lèvres (1 b) est lisse. Le problème posé est le suivant. Lorsqu'après perçage des trous (2a-2b) dans les parois correspondantes des parpaings (2) on positionne la cheville précitée, on constate très souvent une tenue peu stable de la cheville d'ancrage dans la première paroi réceptrice du fût. D'autre part, l'insertion de la cheville à force a tendance à provoquer un élargissement de l'ouverture considérée accentuant ainsi le phénomène de débattement angulaire de la cheville. La fixation obtenue est ainsi peu sécurisante. Il arrive ainsi que la fixation réalisée puisse à la longue se détacher et que le panneau prenne du jeu entraînant des inconvénients sur la planéité de la façade en question. Generally, it is necessary to press against the wall or the wall thus produced by the assembly and assembly of several blocks or bricks, additional insulation panels made in particular polystyrene or equivalent material. To ensure the plating and holding of the aforementioned panels against the walls of bricks or blocks, direct fasteners are used which comprise a long anchor pin made of plastic material, and capable of receiving internally a screw element allowing expansion of the end of the ankle. FIG. 1 shows thus the implementation of such a fixation. The anchor (1) comprises in a known manner along part of its length a longitudinal slot (la) defining two semicylindrical lips (1b) and held together by a plurality of detachable points of projections (1c). when introducing the screw element. The peg has in the region of the lips tabs (1 d) protruding projecting and which are anchored in the corresponding wall or walls through the block or brick. The barrel <B> (If) </ B> of the ankle defined between the head <B> (l </ B> e) and the lips (1b) is smooth. The problem is the following. When after drilling the holes (2a-2b) in the corresponding walls of the blocks (2) is positioned the aforementioned pin, there is very often an unstable behavior of the anchor pin in the first receiving wall of the barrel. On the other hand, the insertion of the ankle force tends to cause a widening of the opening considered thereby accentuating the phenomenon of angular movement of the ankle. The fixation obtained is thus not very secure. It happens so that the fixation made can in the long run come off and the panel takes the game causing inconvenience on the flatness of the facade in question.
Le but recherché selon l'invention a donc été d'améliorer la liaison et la tenue des chevilles d'ancrage et leurs éléments de serrage dans les parpaings ou briques creuses du type précité en garantissant une tenue améliorée, quasi indémontable et sûre. The aim of the invention was therefore to improve the connection and the holding of the anchors and their clamping elements in the hollow blocks or bricks of the aforementioned type ensuring an improved, virtually unmountable and safe hold.
Selon une première caractéristique de l'invention, la fixation directe sur parpaings ou briques creuses du type comprenant une cheville d'ancrage avec une fente transversale longitudinale définissant deux lèvres, avec des points de liaison et des languettes en saillie, est remarquable en ce que la fente transversale longitudinale se prolonge sur la partie fût de ladite cheville très au delà de la zone d'ancrage recevant les languettes en saillie, et en ce que de part et d'autre de la fente et sur le fût, sont disposées des nervures de grande longueur diamétralement opposées et constituant des saillies supplémentaires. According to a first feature of the invention, the direct attachment on hollow blocks or bricks of the type comprising an anchor pin with a longitudinal transverse slot defining two lips, with connecting points and protruding tabs, is remarkable in that the longitudinal transverse slot extends on the barrel portion of said peg much beyond the anchor zone receiving the protruding tabs, and in that on either side of the slot and on the barrel are arranged ribs of great length diametrically opposed and constituting additional projections.
Selon une autre caractéristique, lesdites nervures de grande longueur se situent dans le prolongement axial des languettes en saillie formées sur les lèvres de la cheville d'ancrage. Selon une autre caractéristique, l'élément de vissage assurant l'expansion radiale des lèvres de la cheville est agencé avec une partie filetée selon un filet bois, et en ce que l'extrémité arrière dudit élément de vissage comprend un taraudage intérieur autorisant la fixation d'un boulon de vissage ou équivalent. According to another feature, said long ribs are located in the axial extension of the projecting tabs formed on the lips of the anchor pin. According to another characteristic, the screwing element ensuring the radial expansion of the lips of the dowel is arranged with a threaded part according to a wood net, and in that the rear end of said screwing element comprises an internal thread allowing the fixing a screw bolt or equivalent.
Ces caractéristiques et d'autres encore ressortiront bien de la suite de la description. These and other characteristics will be apparent from the rest of the description.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative illustrée aux figures des dessins. In order to make the object of the invention more concrete, it is now described in a nonlimiting manner illustrated in the figures of the drawings.
La cheville d'ancrage selon l'invention est référencée dans son ensemble par (10), elle est réalisée en matière plastique. Elle est de toute longueur appropriée selon les applications. Elle comprend une zone (10a) d'extrémité formant deux lèvres (1 Ob-lOc) séparées par une fente transversale longitudinale (10e) et des languettes en saillie (10f). Des points de liaison (10g) relient les lèvres entre elles. Ladite cheville est aménagée selon l'invention de manière que la fente (10e) se prolonge dans la zone du fût (l Oh) très au delà de la zone (10a), et sur une partie de la longueur du fût. Des nervures longitudinales (1 Om) sont disposées diamétralement opposées sur le fût et de part et d'autre de la fente longitudinale. Ces nervures sont en saillie. Avantageusement, la longueur (1) de ces nervures est telle qu'elles se prolongent au delà de l'extrémité de la fente, sur le fût précité, en contribuant ainsi à définir une zone de grande longueur pouvant correspondre par exemple à une profondeur au delà de l'épaisseur des parois du parpaing ou brique creuse dans lequel la cheville est insérée. Ces nervures en saillie constituent des éléments de renforcement et de rigidification, mais aussi de tenue et d'ancrage dans l'ouverture établie sur la ou les parois du parpaing ou brique. The anchor pin according to the invention is referenced as a whole by (10), it is made of plastic. It is of any length appropriate to the applications. It comprises an end zone (10a) forming two lips (1 Ob-10c) separated by a longitudinal transverse slot (10e) and projecting tongues (10f). Connecting points (10g) connect the lips together. Said ankle is arranged according to the invention so that the slot (10e) extends in the barrel area (1 Oh) far beyond the zone (10a), and over part of the length of the barrel. Longitudinal ribs (1 Om) are arranged diametrically opposite on the shaft and on either side of the longitudinal slot. These ribs are protruding. Advantageously, the length (1) of these ribs is such that they extend beyond the end of the slot, on the aforementioned barrel, thus helping to define a zone of great length that can correspond for example to a depth at beyond the thickness of the walls of the block or hollow brick in which the peg is inserted. These protruding ribs are reinforcing elements and stiffening, but also holding and anchoring in the opening on the wall or walls of the block or brick.
En variante, il est envisageable de disposer sur le fût d'autres nervures de rigidification dans un nombre quelconque. Alternatively, it is conceivable to have on the barrel other stiffening ribs in any number.
En pratique, ces nervures ont un effet anti-rotation dans les parois du parpaing ou brique en venant s'ancrer dans leur matériau constitutif. In practice, these ribs have an anti-rotation effect in the walls of the block or brick by being anchored in their constituent material.
L'élément de vissage (11) comprend une partie filetée (1 la) établie selon un filet bois, et un fût (l lb) de grande longueur. L'extrémité arrière de l'élément de vissage formant tête (11c) présente un taraudage intérieur (11d) autorisant la fixation d'un élément écrou, boulon ou similaire. The screwing element (11) comprises a threaded portion (1a) established according to a wood net, and a shaft (1b) of great length. The rear end of the head screw member (11c) has an internal thread (11d) for attaching a nut, bolt, or the like.
La fixation directe selon l'invention présente de nombreux avantages et en particulier offre une tenue exceptionnelle de la cheville dans le parpaing ou brique creuse correspondant. La cheville est en effet maintenue en deux endroits sur chacun des parpaings ou briques. Il n'y a plus de possibilité d'élargir les ouvertures de passage. Cela est obtenu notamment par le fait que l'insertion de l'élément de vissage dans le fût provoque immédiatement l'écartement radial des demi-parties cylindriques du fût séparées par la fente en ancrant les nervures longitudinales dans les parois du parpaing. Cette première déformation de la cheville d'ancrage dans la partie fût est essentielle en ce qu'elle contribue à la stabilité de positionnement de la cheville. La poursuite de l'introduction de l'élément de vissage par l'opérateur lui permet de présenter l'extrémité dudit élément vers les lèvres et saillies débordantes de la cheville en provoquant à son tour la seconde déformation de la cheville d'ancrage, la libération des lèvres par la rupture des points de liaison. La tenue de la cheville d'ancrage est ainsi considérablement améliorée. Le taraudage formé sur l'élément de vissage est avantageux en ce qu'il permet la présentation et la fixation immédiate de tout appareil, accessoire destinés à venir plaquer contre le panneau (P). Cette disposition présente des avantages pour les installateurs. L'élément de vissage assure ainsi une double fonction de mise en place et d'écartement de la cheville et de réception à son autre extrémité de tout élément de fixation pour accessoire contre les panneaux.Direct attachment according to the invention has many advantages and in particular offers exceptional holding of the ankle in the corresponding hollow block or hollow brick. The ankle is in fact maintained in two places on each of the blocks or bricks. There is no longer any possibility of widening the openings of passage. This is achieved in particular by the fact that the insertion of the screwing element into the barrel immediately causes the radial spacing of the cylindrical half-portions of the barrel separated by the slot by anchoring the longitudinal ribs in the walls of the block. This first deformation of the anchor pin in the barrel portion is essential in that it contributes to the positioning stability of the ankle. Continuing the introduction of the screw element by the operator allows him to present the end of said element to the lips and projecting projections of the ankle, causing in turn the second deformation of the anchor pin, the release of the lips by the breaking of the points of connection. The holding of the anchor anchor is thus considerably improved. The tapping formed on the screwing element is advantageous in that it allows the presentation and immediate attachment of any device, accessory intended to come to press against the panel (P). This arrangement has advantages for installers. The screwing element thus provides a dual function of setting up and spacing the pin and receiving at its other end any fastener for accessory against the panels.
