Description

La présente invention a trait à un dispositif de fixation d'un garde-corps sur un mur préfabriqué ainsi qu'à un mur préfabriqué comportant au moins un tel dispositif de fixation.The present invention relates to a device for fixing a railing on a prefabricated wall and to a prefabricated wall comprising at least one such fastening device.

Cette invention concerne le domaine du bâtiment et trouvera une utilité toute particulière lorsqu'il s'agit de fixer, de manière temporaire, un garde-corps sur un mur préfabriqué.This invention relates to the field of the building and will find a particular use when it is a question of fixing, temporarily, a railing on a prefabricated wall.

On connaît, d'ores et déjà, des dispositifs conçus pour permettre la fixation, sur un mur préfabriqué, d'un garde-corps ou d'une platine conçue pour recevoir un tel garde-corps. Un tel dispositif adopte la forme d'un ensemble constitué par une cheville ou analogue et par une vis, vissée à l'intérieur d'une telle cheville, ceci pour la fixation, sur le mur, dudit garde-corps ou de ladite platine.Already known, devices designed to allow the attachment, on a prefabricated wall, a railing or a plate designed to receive such a railing. Such a device adopts the form of an assembly consisting of an anchor or the like and a screw, screwed inside of such an ankle, this for fixing, on the wall, said railing or said plate.

Un premier inconvénient d'un tel dispositif consiste en ce que la mise en place d'une telle cheville au sein du mur préfabriqué nécessite, préalablement, le perçage de ce mur préfabriqué. Un tel perçage s'avère être une opération fastidieuse en raison du matériau et des armatures employés pour la réalisation de ce mur. De plus, un tel perçage peut impliquer une intervention en hauteur ce qui nécessite de recourir à un matériel approprié et/ou de prendre des précautions particulières pour garantir la sécurité de l'opérateur en charge d'un tel perçage.A first disadvantage of such a device is that the establishment of such an ankle within the prefabricated wall requires, beforehand, the drilling of this prefabricated wall. Such drilling proves to be a tedious operation because of the material and reinforcements used for the realization of this wall. In addition, such drilling may involve intervention at height which requires the use of appropriate equipment and / or take special precautions to ensure the safety of the operator in charge of such drilling.

Un autre inconvénient consiste en ce que l'immobilisation d'une telle cheville à l'intérieur du mur nécessite de recourir à des chevilles d'un type particulier, notamment à scellement chimique, dont le coût de revient est élevé.Another disadvantage is that the immobilization of such an ankle inside the wall requires the use of pegs of a particular type, including chemical sealing, whose cost is high.

Encore un autre inconvénient consiste en ce que, lors d'une étape ultérieure de la construction du bâtiment, il convient de démonter le garde-corps, ceci en retirant la vis du dispositif de fixation ce qui a pour effet de laisser apparents la cheville ainsi que l'orifice de réception de cette cheville, voire une partie du matériau ayant permis de sceller cette cheville. Il convient, alors, de faire disparaître les traces de la fixation du garde-corps, ce qui implique une intervention supplémentaire sur le mur préfabriqué, qui plus est réalisée en hauteur, ceci avec les inconvénients mentionnés ci-dessus.Yet another disadvantage is that, at a later stage of the construction of the building, it is necessary to disassemble the railing, this by removing the screw of the fastening device which has the effect of leaving visible the peg as well that the receiving hole of this peg, or a part of the material that has sealed this peg. he it is appropriate, then, to remove the traces of the fixing of the railing, which implies an additional intervention on the prefabricated wall, which is carried out in height, this with the disadvantages mentioned above.

On connait, encore, un autre dispositif de fixation comportant au moins une douille, noyée dans le matériau d'une peau du mur, et refermée par un bouchon. Cette douille et son bouchon sont positionnés dans un moule dans lequel est coulé le matériau destiné à constituer la peau du mur, ceci en sorte que ce bouchon affleure à la surface extérieure de cette peau du mur. Lors de la mise en place d'un garde-corps ou d'une platine de réception de ce garde-corps, il est procédé au retrait du bouchon et à la fixation, sur la peau du mur, dudit garde-corps ou de ladite platine, ceci en vissant une vis à l'intérieur de la douille. Là encore, une telle mise en place peut impliquer une opération en hauteur avec les inconvénients mentionnés ci-dessus.There is, again, another fixing device comprising at least one socket, embedded in the material of a skin of the wall, and closed by a plug. This sleeve and its plug are positioned in a mold in which is poured the material intended to form the skin of the wall, so that the plug is flush with the outer surface of the skin of the wall. When setting up a railing or a reception plate of this railing, it is proceeded to the removal of the cap and the fixing, on the skin of the wall, said railing or said platinum, this by screwing a screw inside the socket. Again, such an implementation may involve an operation at height with the disadvantages mentioned above.

De plus, après démontage du garde-corps ou de la platine de réception, le retrait de la vis laisse apparaître la douille ou, tout au moins, l'orifice de cette douille. Il convient, alors, d'occulter la présence de cette douille et/ou de son orifice ce qui est réalisé par une opération de finition du mur qui, d'une part, constitue une opération supplémentaire et, d'autre part et là encore, implique une intervention en hauteur avec les inconvénients mentionnés ci-dessus.In addition, after dismantling the railing or the receiving plate, the removal of the screw reveals the socket or, at least, the orifice of this sleeve. It is advisable, then, to obscure the presence of this socket and / or its orifice which is achieved by a finishing operation of the wall which, on the one hand, constitutes an additional operation and, on the other hand and again , involves intervention at height with the disadvantages mentioned above.

L'on connait, encore, par le document DE 20 2015 104 294 un mur préfabriqué comportant, d'une part, au moins une peau réalisée en un matériau hydraulique et s'étendant selon un plan et, d'autre part, au moins un dispositif de fixation pour fixer, de manière temporaire, un garde-corps sur ce mur préfabriqué. Ce dispositif de fixation comporte un support qui comporte des moyens d'ancrage pour ancrer ce support dans le matériau du mur. Ce support comporte, encore, au moins un orifice ainsi que, d'une part, une première aile s'étendant selon un premier plan, d'autre part, une deuxième aile, comportant le ou les orifices, s'étendant latéralement et extérieurement par rapport à la peau de ce mur ainsi que selon un deuxième plan, parallèle au premier plan, et s'étendant extérieurement par rapport à cette peau et, d'autre part également, une portion de raccordement pour raccorder la première aile et la deuxième aile. Ce dispositif de fixation comporte, encore, une platine, que comporte un garde-corps ou qui comporte des moyens de réception d'un garde-corps, et qui comporte au moins un orifice traversant. Ce dispositif comporte, également, au moins une vis de fixation conçue pour traverser le au moins un orifice traversant de la platine et pour coopérer avec le au moins un orifice du support, ceci en vue de la fixation de la platine sur le support.We know, again, by the document DE 20 2015 104,294 a prefabricated wall comprising, on the one hand, at least one skin made of a hydraulic material and extending in a plane and, on the other hand, at least one fixing device for fixing, temporarily, a railing on this prefabricated wall. This fixing device comprises a support which comprises anchoring means for anchoring this support in the material of the wall. This support also comprises at least one orifice and, firstly, a first wing extending in a first plane, and secondly a second wing, comprising the orifice or orifices, extending laterally and externally. in relation to the skin of the wall as well as in a second plane, parallel to the foreground, and extending externally relative to this skin and, also on the other hand, a connecting portion for connecting the first wing and the second wing. This fixing device further comprises a plate, which comprises a railing or which comprises means for receiving a railing, and which comprises at least one through hole. This device also comprises at least one fixing screw designed to pass through the at least one through-hole of the plate and to cooperate with the at least one orifice of the support, in order to fix the plate on the support.

On observera que, dans ce mur préfabriqué, les moyens d'ancrage comportent des vis d'ancrage, vissées dans la peau du mur, et traversant des orifices traversants que comporte une plaque d'ancrage, que comporte le support, et qui s'étend de manière perpendiculaire à la première aile et à partir de cette première aile.It will be observed that, in this prefabricated wall, the anchoring means comprise anchoring screws, screwed into the skin of the wall, and passing through through orifices which comprises an anchor plate, which comprises the support, and which extends perpendicularly to the first wing and from that first wing.

On observera, également, que ce mur est surmonté par un élément de couverture s'étendant par-dessus la plaque d'ancrage ainsi que par-dessus la première aile. Le dispositif de fixation, décrit dans ce document, est, donc, conçu pour équiper un mur en acrotère, c'est-à-dire un mur se situant à l'extrémité supérieure d'une construction.It will also be observed that this wall is surmounted by a covering element extending over the anchor plate as well as over the first wing. The fixing device, described in this document, is, therefore, designed to equip a wall acroterium, that is to say a wall located at the upper end of a construction.

Un tel dispositif de fixation n'est aucunement adapté pour équiper un mur aval par-dessus lequel on envisage de superposer un mur amont. En effet, dans le cadre d'une telle superposition, les vis d'ancrage ne seraient plus accessibles pour démonter le dispositif de fixation de sorte qu'au moins la première aile (voire encore une partie de plaque d'ancrage) de ce dispositif de fixation resterait visible à l'extérieur de la construction. Pour retirer cette première aile, il convient de découper cette première aile ce qui constitue une intervention, d'une part, longue et fastidieuse et, d'autre part, réalisée en hauteur avec les inconvénients mentionnés ci-dessus.Such a fixing device is not suitable for fitting a downstream wall over which it is planned to superimpose an upstream wall. Indeed, in the context of such a superposition, the anchoring screws would no longer be accessible to dismantle the fixing device so that at least the first wing (or even a part of anchor plate) of this device fastening would remain visible outside the building. To remove the first wing, it is necessary to cut the first wing which is an intervention, on the one hand, long and tedious and on the other hand, carried out in height with the disadvantages mentioned above.

La présente invention se veut de remédier aux inconvénients des dispositifs de fixation de l'état de la technique et des murs préfabriqués comportant de tels dispositifs de fixation.The present invention aims to overcome the disadvantages of prior art fixing devices and prefabricated walls comprising such fasteners.

A cet effet, l'invention concerne un mur préfabriqué comportant, d'une part, au moins une peau réalisée en un matériau hydraulique et s'étendant selon un plan et, d'autre part, au moins un dispositif de fixation pour fixer, de manière temporaire, un garde-corps sur ce mur préfabriqué. Ce dispositif de fixation comporte un support comportant, d'une part, des moyens d'ancrage pour ancrer ce support dans le matériau de la peau ou de l'une des peaux du mur préfabriqué, d'autre part, une première aile qui s'étend selon un premier plan, d'autre part encore, une deuxième aile, qui comporte au moins un orifice, et qui s'étend latéralement et extérieurement par rapport à la peau ou à l'une des peaux de ce mur ainsi que selon un deuxième plan, parallèle au premier plan, et s'étendant extérieurement par rapport à cette peau et parallèlement au plan selon lequel s'étend cette peau et, d'autre part également, une portion de raccordement pour raccorder la première aile et la deuxième aile. Ce dispositif de fixation comporte, aussi, une platine, que comporte un garde-corps ou qui comporte des moyens de réception d'un garde-corps, et qui comporte au moins un orifice traversant. Ce dispositif de fixation comporte, aussi, au moins une vis de fixation conçue pour traverser le au moins un orifice traversant de la platine et pour coopérer avec le au moins un orifice de la deuxième aile du support, ceci en vue de la fixation de la platine sur le support.For this purpose, the invention relates to a prefabricated wall comprising, on the one hand, at least one skin made of a hydraulic material and extending in a plane and, on the other hand, at least one fixing device for fixing, temporarily, a guardrail on this prefabricated wall. This fixing device comprises a support comprising, on the one hand, anchoring means for anchoring this support in the material of the skin or one of the skins of the prefabricated wall, on the other hand, a first wing which is extends in a first plane, on the other hand, a second wing, which has at least one orifice, and which extends laterally and externally relative to the skin or to one of the skins of this wall and according to a second plane, parallel to the foreground, and extending outwardly with respect to this skin and parallel to the plane along which this skin extends and, secondly, also a connecting portion for connecting the first wing and the second wing. This fixing device also comprises a plate, which comprises a railing or which comprises means for receiving a railing, and which comprises at least one through hole. This fastening device also comprises at least one fixing screw designed to pass through the at least one through-hole of the plate and to cooperate with the at least one orifice of the second wing of the support, so as to fix the platinum on the support.

Ce mur préfabriqué est caractérisé par le fait que :

  • les moyens d'ancrage sont constitués au moins en partie par la première aile du support dont au moins une partie de cette première aile s'étend à l'intérieur de la peau du mur préfabriqué ou de l'une des peaux du mur préfabriqué, ceci selon le premier plan qui est au moins parallèle au plan selon lequel s'étend cette peau;
  • ledit au moins un orifice de la deuxième aile est constitué par au moins un orifice taraudé tandis que ladite au moins une vis de fixation est conçue pour coopérer par vissage avec le au moins un orifice taraudé de la deuxième aile du support.
This prefabricated wall is characterized by the fact that:
  • the anchoring means are constituted at least in part by the first support flange of which at least a part of this first flange extends inside the skin of the prefabricated wall or one of the skins of the prefabricated wall, this according to the first plane which is at least parallel to the plane according to which this skin extends;
  • said at least one orifice of the second flange is constituted by at least one threaded orifice while said at least one less a fixing screw is designed to cooperate by screwing with the at least one threaded orifice of the second wing of the support.

Une caractéristique additionnelle concerne le fait que la platine comporte des moyens de protection pour protéger la ou les vis de fixation contre un contact avec un matériau de construction.An additional feature is that the plate has protective means to protect the fixing screw (s) against contact with a construction material.

Encore une autre caractéristique consiste en ce que la platine comporte des moyens d'appui pour permettre à cette platine de prendre appui sur le chant supérieur du mur.Yet another feature is that the plate has support means to allow the plate to bear on the upper edge of the wall.

Une caractéristique additionnelle concerne le fait que la platine comporte des moyens de guidage pour guider la ou les vis de fixation en direction du ou des orifices taraudés du support. En fait, ces moyens de guidage sont constitués par au moins un canal de guidage défini par une partie des moyens de protection ainsi que par une partie des moyens d'appui.An additional feature is that the plate has guide means for guiding the fixing screw (s) towards the threaded hole (s) of the support. In fact, these guide means are constituted by at least one guide channel defined by a part of the protection means and by a part of the support means.

L'invention concerne, encore, un mur préfabriqué tel que susmentionné et comportant, d'une part, deux peaux, réalisées en un matériau hydraulique, raccordées entre elles par des moyens de raccordement, et positionnées à une distance déterminée l'une de l'autre en sorte de définir un volume interne audit mur préfabriqué. Dans ce mur préfabriqué, le au moins un dispositif de fixation présente les caractéristiques décrites ci-dessus et la première aile du support d'un tel dispositif de fixation s'étend à l'intérieur de l'une des deux peaux du mur préfabriqué tandis que la deuxième aile du support d'un tel dispositif de fixation s'étend dans le prolongement du volume interne du mur préfabriqué, ceci latéralement et extérieurement par rapport à cette peau du mur préfabriqué.The invention also relates to a prefabricated wall as mentioned above and comprising, on the one hand, two skins, made of a hydraulic material, connected together by connecting means, and positioned at a determined distance from one another. other in order to define an internal volume to said prefabricated wall. In this prefabricated wall, the at least one fixing device has the characteristics described above and the first support wing of such a fixing device extends inside one of the two skins of the prefabricated wall while that the second wing of the support of such a fixing device extends in the extension of the internal volume of the prefabricated wall, this laterally and externally with respect to this skin of the prefabricated wall.

Ainsi, le dispositif de fixation comporte un support comportant des moyens d'ancrage de ce dispositif dans le matériau du mur préfabriqué. Ceci permet, avantageusement et pour équiper un tel mur préfabriqué avec un tel support, de positionner ce support dans un moule lors de la fabrication en usine du mur préfabriqué et évite de devoir percer un tel mur préfabriqué (voire d'y sceller une cheville) et/ou d'intervenir en hauteur.Thus, the fixing device comprises a support comprising means for anchoring this device in the material of the prefabricated wall. This makes it possible, advantageously and to equip such a prefabricated wall with such a support, to position this support in a mold during factory manufacture of the prefabricated wall and avoids having to drill such a wall. prefabricated (or even seal ankle) and / or intervene in height.

Un tel dispositif de fixation comporte, encore, une platine comportant des moyens de protection pour protéger la ou les vis de fixation contre un contact avec un matériau de construction. De tels moyens de protection permettent, avantageusement, d'éviter à une telle vis d'être bloquée par un tel matériau de construction et de toujours préserver la possibilité d'actionner une telle vis, plus particulièrement en vue de son retrait.Such a fixing device also comprises a plate comprising protection means for protecting the fixing screw or screws against contact with a construction material. Such protection means advantageously make it possible to prevent such a screw from being blocked by such a construction material and to always preserve the possibility of actuating such a screw, more particularly with a view to its removal.

La platine de ce dispositif de fixation comporte, aussi, des moyens de guidage pour guider la ou les vis de fixation en direction du ou des orifices taraudés du support. La présence de ces moyens de guidage permet, avantageusement, d'assurer un positionnement approprié de la ou des vis de fixation par rapport au support, plus particulièrement par rapport à l'orifice taraudé ou aux orifices taraudés que comporte la deuxième aile de ce support laquelle, en raison de l'épaisseur de la peau du mur, est positionnée en retrait par rapport à une face avant du mur préfabriqué, destinée à être orientée vers l'extérieur d'une construction, et à partir de laquelle la platine est fixée sur le support.The plate of this fixing device also comprises guiding means for guiding the fixing screw (s) towards the threaded hole (es) of the support. The presence of these guiding means advantageously makes it possible to ensure appropriate positioning of the fixing screw or screws with respect to the support, more particularly with respect to the threaded orifice or to the threaded orifices which the second wing of this support comprises. which, because of the thickness of the skin of the wall, is positioned recessed with respect to a front face of the prefabricated wall, intended to be oriented towards the outside of a building, and from which the plate is fixed on the support.

De manière avantageuse, ces moyens de guidage sont constitués par au moins un canal de guidage défini par une partie des moyens de protection ainsi que par une partie de moyens d'appui, que comporte la platine, et qui sont conçus pour permettre à cette platine de prendre appui sur le chant supérieur du mur.Advantageously, these guiding means consist of at least one guiding channel defined by a part of the protection means as well as by a part of support means, which comprises the plate, and which are designed to allow this plate to take support on the upper edge of the wall.

L'invention concerne, alors, un mur préfabriqué comportant au moins une peau réalisée en un matériau hydraulique ainsi qu'au moins un dispositif de fixation présentant les caractéristiques décrites ci-dessus. En particulier, ce dispositif de fixation comporte une deuxième aile, comportant au moins un orifice taraudé, et s'étendant, d'une part, latéralement et extérieurement par rapport au mur préfabriqué ainsi que par rapport à la peau de ce mur à l'intérieur de laquelle s'étend la première aile d'un tel dispositif de fixation, et, d'autre part, selon un deuxième plan, parallèle au plan selon lequel s'étend ladite peau, et s'étendant extérieurement par rapport à cette peau.The invention relates, then, to a prefabricated wall comprising at least one skin made of a hydraulic material and at least one fixing device having the characteristics described above. In particular, this fixing device comprises a second wing, comprising at least one threaded orifice, and extending, on the one hand, laterally and externally with respect to the prefabricated wall as well as with respect to the skin of this wall at the interior of which extends the first wing of such a device fixation, and, secondly, in a second plane, parallel to the plane along which said skin extends, and extending outwardly with respect to this skin.

Une telle caractéristique permet, avantageusement, un positionnement d'un mur préfabriqué amont par-dessus un mur préfabriqué aval comportant le ou les dispositifs de fixation, ceci sans qu'un tel dispositif de fixation n'entrave une telle superposition. En particulier, cette caractéristique permet, avantageusement, à la deuxième aile du support du dispositif de fixation du mur préfabriqué aval d'être positionnée, par rapport à une peau du mur préfabriqué amont, ceci de manière décalée, plus particulièrement dans le volume interne d'un tel mur préfabriqué amont, ceci sans entraver cette superposition.Such a feature advantageously allows a positioning of an upstream prefabricated wall over a downstream prefabricated wall comprising the fixing device or devices, this without such a fixing device hinders such a superposition. In particular, this characteristic advantageously allows the second wing of the support of the downstream prefabricated wall fixing device to be positioned, with respect to a skin of the upstream prefabricated wall, in a staggered manner, more particularly in the internal volume of the wall. such an upstream prefabricated wall, without hindering this superposition.

Cette caractéristique permet, également, de positionner le support d'un tel dispositif de fixation en sorte que le ou les orifices taraudés, que comporte un tel support, ne soient pas visibles en face avant et/ou externe du mur préfabriqué, ceci après retrait de la ou des vis de fixation et, donc, après démontage du garde-corps ou de la platine de réception d'un tel garde-corps. Etant donné que ce ou ces orifices ne sont pas visibles, il n'est pas nécessaire d'en assurer l'occultation par une intervention additionnelle, notamment réalisée en hauteur.This characteristic also makes it possible to position the support of such a fastening device so that the threaded hole or openings, which such a support comprises, are not visible on the front and / or outer face of the prefabricated wall, this after withdrawal. of the fixing screw or screws and, therefore, after dismantling the railing or the receiving plate of such a railing. Since this or these orifices are not visible, it is not necessary to ensure the occultation by additional intervention, especially performed in height.

D'autres buts et avantages de la présente invention apparaîtront au cours de la description qui va suivre se rapportant à des modes de réalisation qui ne sont donnés qu'à titre d'exemples indicatifs et non limitatifs.Other objects and advantages of the present invention will become apparent from the following description relating to embodiments which are given by way of indicative and non-limiting examples.

La présente invention concerne le domaine du bâtiment et trouvera une utilité toute particulière lorsqu'il s'agit de fixer, de manière temporaire, un garde-corps sur un mur préfabriqué.The present invention relates to the field of the building and will find a particular use when it is a question of fixing, temporarily, a railing on a prefabricated wall.

En fait, un tel mur préfabriqué 1 comporte au moins une peau (2 ; 2') réalisée en un matériau hydraulique, plus particulièrement constitué par du béton.In fact, such a prefabricated wall 1 comprises at least one skin (2; 2 ') made of a hydraulic material, more particularly constituted by concrete.

Une telle peau (2 ; 2') présente, d'une part, une face avant 20 destinée à être orientée vers l'extérieur d'une construction et, d'autre part, une face arrière 21 destinée à être orientée vers l'intérieur d'une construction. Une telle peau (2 ; 2') présente, également, un chant supérieur 22 s'étendant selon un plan.Such skin (2; 2 ') has, on the one hand, a front face 20 intended to be oriented towards the outside of a construction and, on the other hand, a rear face 21 intended to be oriented towards the inside a building. Such skin (2; 2 ') also has an upper edge 22 extending in a plane.

Selon un premier type de réalisation non représenté, un tel mur préfabriqué 1 comporte une unique peau 2, réalisée en un tel matériau hydraulique, et s'étendant selon un plan.According to a first type of embodiment not shown, such a prefabricated wall 1 comprises a single skin 2, made of such a hydraulic material, and extending in a plane.

Selon un deuxième type de réalisation, un tel mur préfabriqué 1 comporte, d'une part, deux peaux (2 ; 2'), réalisées en un matériau hydraulique (plus particulièrement constitué par du béton), raccordées entre elles par des moyens de raccordement (non représentés), et positionnées à une distance déterminée l'une (2 ; 2') de l'autre (2' ; 2) en sorte de définir un volume interne 3 audit mur préfabriqué 1.According to a second type of embodiment, such a prefabricated wall 1 comprises, on the one hand, two skins (2; 2 '), made of a hydraulic material (more particularly constituted by concrete), connected together by connecting means. (not shown), and positioned at a determined distance one (2; 2 ') from the other (2'; 2) so as to define an internal volume 3 to said prefabricated wall 1.

Les deux peaux (2 ; 2') de ce mur préfabriqué 1 s'étendent, chacune, selon un plan tandis que les plans selon lesquels s'étendent ces deux peaux (2 ; 2') sont parallèles.The two skins (2; 2 ') of this prefabricated wall 1 extend each in a plane while the planes along which these two skins (2; 2') extend are parallel.

Un premier mode de réalisation de ce deuxième type de réalisation concerne un mur préfabriqué 1 dont le volume interne 3 est dépourvu d'une couche d'un matériau isolant. Un tel mur préfabriqué 1 est usuellement connu sous la dénomination de « mur précoffré », « mur précoffré classique », ou « mur à coffrage intégré » (MCI).A first embodiment of this second embodiment relates to a prefabricated wall 1 whose internal volume 3 is devoid of a layer of an insulating material. Such a prefabricated wall 1 is usually known by the name of "Precast wall", "conventional precast wall", or "integrated form wall" (ICM).

Un deuxième mode de réalisation de ce deuxième type de réalisation, illustré dans les figures en annexe, concerne un mur préfabriqué 1 comportant un panneau 4, réalisé en un matériau isolant thermique (laine de roche, polystyrène, polyuréthane ou analogue), positionné à l'intérieur du volume interne 3 du mur préfabriqué 1, ceci à proximité d'une 2 des peaux (2 ; 2') du mur préfabriqué 1 ou en applique contre cette peau 2. En fait, un tel panneau 4 est usuellement positionné à proximité ou (et de préférence) en applique contre la peau 2 externe du mur préfabriqué 1, c'est-à-dire la peau 2 destinée à être orientée en direction de l'extérieur de la construction au moins en partie réalisée avec un tel mur préfabriqué 1.A second embodiment of this second embodiment, illustrated in the figures in the appendix, relates to a prefabricated wall 1 comprising a panel 4, made of a thermal insulating material (rockwool, polystyrene, polyurethane or the like), positioned at a distance of interior of the internal volume 3 of the prefabricated wall 1, this close to a 2 of the skins (2; 2 ') of the prefabricated wall 1 or applied against this skin 2. In fact, such a panel 4 is usually positioned near or (and preferably) applied against the outer skin 2 of the prefabricated wall 1, that is to say the skin 2 intended to be oriented towards the outside of the construction at least partly made with such a wall prefabricated 1.

Un tel mur préfabriqué 1 est usuellement connu sous la dénomination de « mur précoffré thermique » ou « mur à coffrage intégré isolant » (MCII).Such a prefabricated wall 1 is usually known as "thermal precoated wall" or "insulating integrated form wall" (MCII).

L'invention concerne, en fait, un dispositif de fixation 5 pour fixer, de manière temporaire, un garde-corps (non représenté) sur un mur préfabriqué 1 tel que décrit ci-dessus.The invention relates, in fact, a fastening device 5 for temporarily fixing a railing (not shown) on a prefabricated wall 1 as described above.

Un tel dispositif de fixation 5 comporte un support 6 qui comporte, d'une part, des moyens d'ancrage 7 pour ancrer ce support 6 dans le matériau du mur préfabriqué 1 et, d'autre part, au moins un orifice taraudé (8 ; 8').Such a fixing device 5 comprises a support 6 which comprises, on the one hand, anchoring means 7 for anchoring the support 6 in the material of the prefabricated wall 1 and, on the other hand, at least one threaded orifice (8 8 ').

Tel que visible sur les figures 1 à 3, ledit support 6 comporte, d'une part, une première aile 60, constituant au moins en partie les moyens d'ancrage 7, et s'étendant selon un premier plan, d'autre part, une deuxième aile 61, comportant le ou les orifices taraudés (8 ; 8'), et s'étendant selon un deuxième plan parallèle au première plan et, d'autre part encore, une portion de raccordement 62 pour raccorder la première aile 60 et la deuxième aile 61.As visible on the Figures 1 to 3 said support 6 comprises, on the one hand, a first flange 60, constituting at least partly the anchoring means 7, and extending in a first plane, on the other hand, a second wing 61, comprising the or the threaded orifices (8; 8 '), and extending along a second plane parallel to the first plane and, secondly, a connecting portion 62 for connecting the first wing 60 and the second wing 61.

En fait et tel que visible sur ces figures 1 à 3, la première aile 60 se situe dans le prolongement de la portion de raccordement 62 et s'étend à partir d'une extrémité de cette portion de raccordement 62, ceci dans une direction déterminée. La deuxième aile 61 se situe également dans le prolongement de la portion de raccordement 62 et s'étend à partir d'une extrémité opposée (plus particulièrement opposée à celle à partir de laquelle s'étend la première aile 60) de cette portion de raccordement 62, ceci dans une direction opposée à celle de la première aile 60.In fact and as visible on these Figures 1 to 3 , the first flange 60 is in the extension of the connecting portion 62 and extends from one end of this connecting portion 62, this in a specific direction. The second wing 61 is also in the extension of the connecting portion 62 and extends from an opposite end (more particularly opposite to that from which the first flange 60 extends) of this connecting portion. 62, this in a direction opposite to that of the first wing 60.

Plus précisément, cette première aile 60 et cette deuxième aile 61 s'étendent à partir de la portion de raccordement 62, ceci selon une direction perpendiculaire à une direction générale selon laquelle s'étend cette portion de raccordement 62.More precisely, this first wing 60 and this second wing 61 extend from the connecting portion 62, in a direction perpendicular to a general direction along which this connecting portion 62 extends.

Tel que visible sur la figure 2, ce support 6 est constitué par une unique pièce comportant la première aile 60, la deuxième aile 61 ainsi que la portion de raccordement 62 pour raccorder cette première aile 60 et cette deuxième aile 61.As visible on the figure 2 this support 6 is constituted by a single piece comprising the first wing 60, the second wing 61 and the connecting portion 62 for connecting the first wing 60 and the second wing 61.

Cette unique pièce présente une section en forme de « S » ou de marche d'escalier.This single piece has an "S" shaped section or stair step.

De manière alternative ou (et de préférence) additionnelle, cette unique pièce est constituée par une plaque métallique comportant au moins une déformation définissant la première aile 60, la deuxième aile 61 et/ou la portion de raccordement 62.Alternatively or (and preferably) additional, this single piece is constituted by a metal plate having at least one deformation defining the first flange 60, the second flange 61 and / or the connecting portion 62.

Une autre caractéristique consiste en ce que ledit support 6 comporte encore un organe d'ancrage 70, constituant en partie les moyens d'ancrage 7, équipant la première aile 60 du support 6, et s'étendant à partir de cette première aile 60 du support 6.Another feature is that said support 6 further comprises an anchoring member 70, constituting part of the anchoring means 7, equipping the first flange 60 of the support 6, and extending from this first flange 60 of the support 6.

Ledit organe d'ancrage 70 s'étend selon un plan parallèle au premier plan selon lequel s'étend la première aile 60 du support 6. Cet organe d'ancrage s'étend, de préférence, dans une direction opposée à celle dans laquelle s'étend la première aile 60.Said anchoring member 70 extends in a plane parallel to the first plane according to which the first flange 60 of the support 6 extends. This anchoring member extends, preferably, in a direction opposite to that in which s 'extends the first wing 60.

Quoi qu'il en soit, ledit organe d'ancrage 70 est solidaire de la première aile 60 du support 6, plus particulièrement par une soudure.Anyway, said anchoring member 70 is secured to the first flange 60 of the support 6, more particularly by a weld.

Un tel organe d'ancrage 70 est constitué par au moins une tige ou (et de préférence comme visible sur les figures 1 à 3 en annexe) par une pièce adoptant une forme en « U » et comportant deux tiges, notamment parallèles.Such an anchoring member 70 is constituted by at least one rod or (and preferably as visible on the Figures 1 to 3 in annex) by a piece adopting a "U" shape and comprising two rods, in particular parallel.

Le dispositif de fixation 5 comporte, encore, une platine 9, que comporte un garde-corps (non représenté) ou (et de préférence comme visible sur les figures en annexe) qui comporte des moyens de réception 10 pour recevoir un tel garde-corps (non représenté).The fixing device 5 further comprises a plate 9, which comprises a railing (not shown) or (and preferably as visible in the appended figures) which comprises receiving means 10 for receiving such a railing (not shown)

Tel que visible sur la figure 5, de tels moyens de réception 10 peuvent adopter la forme d'une rainure (notamment de section en « T ») conçue apte à coopérer avec une nervure (ou analogue) que comporte ou qui équipe un garde-corps (non représenté). C'est, plus particulièrement, un côté antérieur, que comporte ladite platine 9, qui comporte alors de tels moyens de réception 10.As visible on the figure 5 such receiving means 10 may take the form of a groove (in particular of "T" section) designed adapted to cooperate with a rib (or the like) that includes or equips a railing (not shown). It is, more particularly, an anterior side, that comprises said plate 9, which then comprises such receiving means 10.

Ladite platine 9 comporte, encore, au moins un orifice traversant (11 ; 11').Said platen 9 also comprises at least one through orifice (11; 11 ').

Le dispositif de fixation 5 comporte, alors également, au moins une vis de fixation (12 ; 12') conçue pour traverser le au moins un orifice traversant (11 ; 11') de la platine 9 et pour coopérer par vissage avec le au moins un orifice taraudé (8 ; 8') du support 6, ceci en vue de la fixation de la platine 9 sur le support 6 et, par conséquent, de la fixation du garde-corps sur le mur préfabriqué 1.The fastening device 5 also comprises at least one fastening screw (12; 12 ') designed to pass through the at least one through hole (11; 11') of the plate 9 and to cooperate by screwing with the at least one a threaded orifice (8; 8 ') of the support 6, this for fixing the plate 9 on the support 6 and, consequently, the fixing of the railing on the prefabricated wall 1.

Une autre caractéristique consiste en ce que la platine 9 comporte des moyens de protection 13 pour protéger la ou les vis de fixation (12 ; 12') contre un contact avec un matériau de construction.Another feature is that the plate 9 has protection means 13 for protecting the fixing screw or screws (12; 12 ') against contact with a construction material.

En fait, un tel matériau de construction peut être constitué par le matériau (plus particulièrement constitué par du béton) d'une dalle coopérant avec le mur préfabriqué 1 qui comporte ledit dispositif de fixation 5.In fact, such a building material may consist of the material (more particularly constituted by concrete) of a slab cooperating with the prefabricated wall 1 which comprises said fixing device 5.

Ce matériau de construction peut, encore, être constitué par le matériau (notamment du béton) de remplissage du volume interne 3 d'un mur préfabriqué 1 (qui comporte ledit dispositif de fixation 5, notamment un mur préfabriqué isolant 1) ou d'un joint horizontal entre deux murs préfabriqués 1 superposés (et dont le mur préfabriqué 1 inférieur comporte ledit dispositif de fixation 5).This construction material may also be constituted by the material (especially concrete) for filling the internal volume 3 of a prefabricated wall 1 (which comprises said fixing device 5, in particular an insulating prefabricated wall 1) or a horizontal joint between two prefabricated walls 1 superimposed (and whose lower prefabricated wall 1 comprises said fixing device 5).

Finalement, ce matériau de construction peut, encore, être constitué par le matériau de construction d'une peau d'un mur préfabriqué superposé au mur préfabriqué 1 qui comporte ledit dispositif de fixation 5.Finally, this building material may, again, be constituted by the material of construction of a skin of a prefabricated wall superimposed on the prefabricated wall 1 which comprises said fixing device 5.

En fait, ces moyens de protection 13 permettent, avantageusement, d'éviter à une vis (12 ; 12') d'être bloquée (notamment en étant noyée, voire ancrée, dans le béton ou en étant écrasée par une peau d'un mur préfabriqué superposé) et ainsi de toujours préserver la possibilité d'actionner une telle vis (12 ; 12'), plus particulièrement en vue de son retrait.In fact, these protection means 13 advantageously make it possible to prevent a screw (12; 12 ') from being blocked (in particular by being embedded, even anchored, in the concrete or by being crushed by a skin of a superimposed prefabricated wall) and thus always preserve the possibility of actuating such a screw (12; 12 '), more particularly with a view to its removal.

Tel que visible sur les figures 4 à 6, les moyens de protection 13 sont constitués par un déflecteur 130, solidaire de la platine 9 (notamment par une soudure), et s'étendant latéralement à partir de cette platine 9, plus particulièrement dans une direction globalement perpendiculaire à un plan selon lequel s'étend cette platine 9.As visible on the Figures 4 to 6 , the protection means 13 are constituted by a baffle 130, integral with the plate 9 (in particular by a weld), and extending laterally from this plate 9, more particularly in a direction generally perpendicular to a plane according to which s 'extends this deck 9.

On observera que ce déflecteur 130 s'étend à partir d'un côté postérieur de la platine 9, opposé au côté antérieur de cette platine 9 comportant les moyens de réception 10 susmentionnés.It will be observed that this deflector 130 extends from a rear side of the plate 9, opposite the front side of this plate 9 having the aforementioned receiving means 10.

En fait, ce déflecteur 130 s'étend, à partir de cette platine 9, en direction du support 6, ceci en position de fixation de cette platine 9 sur ce support 6.In fact, this deflector 130 extends, from this plate 9, towards the support 6, this in the fixing position of this plate 9 on this support 6.

Tel que visible sur les figures 4 et 5, ledit déflecteur 130 comporte une aile 131 ainsi que deux rabats (132 ; 132'), se situant dans le prolongement de l'aile 131, et s'étendant chacun à partir d'une extrémité latérale de cette aile 131.As visible on the figures 4 and 5 , said deflector 130 comprises a wing 131 and two flaps (132; 132 '), located in the extension of the wing 131, and each extending from a lateral end of the wing 131.

En fait, ladite aile 131 s'étend à partir de la platine 9, ceci dans une direction perpendiculaire au plan selon lequel s'étend cette platine 9.In fact, said wing 131 extends from the plate 9, this in a direction perpendicular to the plane along which this plate 9 extends.

Lesdits rabats (132 ; 132') s'étendent, d'une part, à partir de ladite platine 9 et, d'autre part, à partir de ladite aile 131, ceci dans une même direction et/ou dans une direction sensiblement perpendiculaire à un plan selon lequel s'étend ladite aile 131.Said flaps (132; 132 ') extend, on the one hand, from said plate 9 and, on the other hand, from said wing 131, this in the same direction and / or in one direction substantially perpendicular to a plane along which said wing 131 extends.

En fait, ledit déflecteur 130 présente une section en « U » renversé.In fact, said deflector 130 has an inverted "U" section.

Tel que visible sur la figure 5, l'aile 131 est positionnée en amont de l'orifice traversant 11 ou des orifices traversant (11 ; 11') de la platine 9 tandis que les rabats (132 ; 132') sont positionnés de part et d'autre de cet orifice traversant 11 ou de ces orifices traversant (11 ; 11') et s'étendent en aval de l'aile 131, ceci en position de service de la platine 9.As visible on the figure 5 , the flange 131 is positioned upstream of the through-orifice 11 or the through holes (11; 11 ') of the plate 9 while the flaps (132; 132') are positioned on either side of this orifice 11 or 11 'and extending downstream of the wing 131, this in the service position of the plate 9.

Il en découle que l'orifice traversant 11 ou les orifices traversant (11 ; 11') sont positionnés, d'une part, entre les rabats (132 ; 132') du déflecteur 130 et, d'autre part, en dessous de ladite aile 131.It follows that the through orifice 11 or the through orifices (11; 11 ') are positioned, on the one hand, between the flaps (132; 132') of the deflector 130 and, on the other hand, below said wing 131.

Une autre caractéristique consiste en ce qu'au moins une partie du déflecteur 130 présente une forme en dépouille. En effet et tel que visible sur la figure 6, les rabats (132 ; 132') du déflecteur 130 s'étendent à partir de la platine 9, ceci en convergeant. Une telle forme en dépouille permet, avantageusement, de faciliter le démontage du dispositif de fixation 5, plus particulièrement le retrait de la platine 9 hors d'un interstice ménagé entre deux murs préfabriqués 1 superposés, voire au moins en partie rempli par un matériau de construction (notamment du béton).Another feature is that at least a portion of the baffle 130 has a flush shape. Indeed and as visible on the figure 6 , the flaps (132; 132 ') of the deflector 130 extend from the plate 9, this converging. Such a flank shape advantageously makes it possible to dismantle the fastening device 5, more particularly the removal of the plate 9 from a gap formed between two prefabricated walls 1 superimposed, or even at least partially filled with a material of construction (including concrete).

Encore une autre caractéristique consiste en ce que la platine 9 comporte des moyens d'appui 14 pour permettre à cette platine 9 de prendre appui sur le chant supérieur du mur préfabriqué 1, plus particulièrement sur le chant supérieur d'une peau 2 (notamment la peau externe 2) de ce mur préfabriqué 1.Yet another characteristic is that the plate 9 comprises support means 14 to allow the plate 9 to bear on the upper edge of the prefabricated wall 1, more particularly on the upper edge of a skin 2 (especially the outer skin 2) of this prefabricated wall 1.

Tel que visible sur les figures en annexe, ces moyens d'appui 14 sont constitués par une gouttière 140 solidaire de la platine 9 (notamment par une soudure) et s'étendant latéralement à partir de cette platine 9, plus particulièrement dans une direction globalement perpendiculaire à un plan selon lequel s'étend cette platine 9.As can be seen in the appended figures, these support means 14 are constituted by a channel 140 secured to the plate 9 (in particular by a weld) and extending laterally from this plate 9, more particularly in a direction generally. perpendicular to a plane according to which this plate 9 extends.

On observera que cette gouttière 140 s'étend à partir du côté postérieur de la platine 9, opposé au côté antérieur de cette platine 9 comportant les moyens de réception 10 susmentionnés.It will be observed that this channel 140 extends from the rear side of the plate 9, opposite to the front side of this plate 9 having the aforementioned receiving means 10.

En fait, cette gouttière 140 s'étend, à partir de cette platine 9, en direction du support 6, ceci en position de fixation de cette platine 9 sur ce support 6.In fact, this channel 140 extends, from this plate 9, towards the support 6, this in the fixing position of this plate 9 on the support 6.

Tel que visible sur les figures 4 et 5, ladite gouttière 140 comporte une aile 141 ainsi que deux rabats (142 ; 142'), se situant dans le prolongement de l'aile 141, et s'étendant chacun à partir d'une extrémité latérale de cette aile 141.As visible on the figures 4 and 5 , said channel 140 comprises a wing 141 and two flaps (142; 142 '), located in the extension of the wing 141, and each extending from a lateral end of the wing 141.

En fait, ladite aile 141 s'étend à partir de la platine 9, ceci dans une direction perpendiculaire au plan selon lequel s'étend cette platine 9.In fact, said wing 141 extends from the plate 9, this in a direction perpendicular to the plane along which this plate 9 extends.

Cette aile 141 présente une surface d'appui 143 conçue pour prendre appui sur le chant supérieur du mur préfabriqué 1.This wing 141 has a bearing surface 143 designed to bear on the upper edge of the prefabricated wall 1.

Lesdits rabats (142 ; 142') s'étendent, d'une part, à partir de ladite platine 9 et, d'autre part, à partir de ladite aile 141, ceci dans une même direction et/ou dans une direction sensiblement perpendiculaire à un plan selon lequel s'étend ladite aile 131 et/ou dans une direction perpendiculaire au plan selon lequel s'étend cette platine 9 et/ou parallèlement entre eux et/ou en direction de l'aile 131 des moyens de protection 13.Said flaps (142; 142 ') extend, on the one hand, from said plate 9 and, on the other hand, from said wing 141, this in the same direction and / or in a substantially perpendicular direction to a plane along which said wing 131 extends and / or in a direction perpendicular to the plane along which this plate 9 extends and / or parallel to each other and / or in the direction of the wing 131 of the protection means 13.

En fait, ladite gouttière 140 présente une section en « U ».In fact, said channel 140 has a section "U".

Tel que visible sur la figure 5, l'aile 141 est positionnée en aval de l'orifice traversant 11 ou des orifices traversant (11 ; 11') de la platine 9 tandis que les rabats (142 ; 142') sont positionnés entre ces orifices traversant (11 ; 11') et s'étendent en amont de l'aile 141, ceci en position de service de la platine 9.As visible on the figure 5 the flange 141 is positioned downstream of the through hole 11 or the through holes (11; 11 ') of the plate 9 while the flaps (142; 142') are positioned between these through holes (11; 11 ') ) and extend upstream of the wing 141, in the service position of the plate 9.

Il en découle que les rabats (142 ; 142') de la gouttière 140 sont positionnés entre les orifices traversant (11 ; 11') tandis que l'aile 141 de cette gouttière 140 est positionnée en dessous de ces orifices traversant (11 ; 11'). Ceci permet, avantageusement et lorsque la platine 9 repose sur le chant supérieur du mur préfabriqué 1, à la vis de fixation 12 ou aux vis de fixation (12 ; 12') de se positionner dans l'interstice entre deux murs préfabriqués 1 superposés.It follows that the flaps (142; 142 ') of the channel 140 are positioned between the through holes (11; 11') while the flange 141 of this channel 140 is positioned below these through holes (11; '). This allows, advantageously and when the plate 9 rests on the upper edge of the prefabricated wall 1, the fixing screw 12 or the fixing screws (12; 12 ') to be positioned in the gap between two prefabricated walls 1 superimposed.

Selon une autre caractéristique, ladite gouttière 140 est surmontée par le déflecteur 130 qui coiffe, en fait, ladite gouttière 140 laquelle s'étend par-dessus l'intégralité de cette gouttière 140.According to another characteristic, said channel 140 is surmounted by the deflector 130 which caps, in fact, said channel 140 which extends over the entire of this channel 140.

L'aile 141 de la gouttière 140 est sensiblement parallèle à l'aile 131 du déflecteur 130 des moyens de protection 13 tandis que les rabats (142 ; 142') de la gouttière 140 s'étendent en direction de l'aile 131 du déflecteur 130 de ces moyens de protection 13.The flange 141 of the gutter 140 is substantially parallel to the flange 131 of the deflector 130 of the protection means 13 while the flaps (142; 142 ') of the gutter 140 extend towards the flange 131 of the deflector 130 of these protection means 13.

Une autre caractéristique du dispositif de fixation 5 consiste en ce que la platine 9 comporte des moyens de guidage 15 pour guider la vis de fixation 12 ou les vis de fixation (12 ; 12') en direction du ou des orifices taraudés (8 ; 8') du support 6.Another characteristic of the fixing device 5 consists in that the plate 9 comprises guide means 15 for guiding the fastening screw 12 or the fastening screws (12; 12 ') in the direction of the threaded orifice (8; ') of the support 6.

En fait, de tels moyens de guidage 15 sont constitués par au moins un canal de guidage défini par une partie des moyens de protection 13 ainsi que par une partie des moyens d'appui 14.In fact, such guide means 15 consist of at least one guide channel defined by a part of the protection means 13 as well as by a part of the support means 14.

Plus précisément, un tel canal de guidage est défini, d'une part, par les rabats (131 ; 131') du déflecteur 130 des moyens de protection 13, d'autre part, par les rabats (142 ; 142') de la gouttière 140 des moyens d'appui 14 et, d'autre part encore, par une partie de l'aile 131 du déflecteur 130 de ces moyens de protection 13.More specifically, such a guide channel is defined, on the one hand, by the flaps (131; 131 ') of the deflector 130 of the protection means 13, on the other hand, by the flaps (142, 142') of the gutter 140 support means 14 and, secondly, by a portion of the wing 131 of the deflector 130 of these protection means 13.

Finalement, la platine 9 comporte, encore, des moyens de guidage pour guider un mur préfabriqué 1 superposé, ceci lors du positionnement de celui-ci par-dessus un mur préfabriqué 1 comportant le dispositif de fixation 5 comportant ladite platine 9.Finally, the plate 9 comprises, again, guide means for guiding a prefabricated wall 1 superimposed, this during the positioning thereof over a prefabricated wall 1 comprising the fixing device 5 comprising said plate 9.

En fait, ces moyens de guidage sont constitués par une partie du côté postérieur de la platine 9, opposé au côté antérieur de cette platine 9 comportant les moyens de réception 10, et comportant les moyens de protection 13 et/ou les moyens d'appui 14.In fact, these guide means are constituted by a portion of the rear side of the plate 9, opposite to the front side of this plate 9 comprising the receiving means 10, and comprising the protection means 13 and / or the support means 14.

On observera que cette partie de côté postérieur est, de préférence, constituée par une partie supérieure d'un tel côté postérieur s'étendant à partir desdits moyens de protection 13 et en direction d'une extrémité libre de cette platine 9.It will be observed that this posterior side portion is preferably constituted by an upper part of such a posterior side extending from said protection means 13 and toward a free end of this plate 9.

A ce propos, on remarquera que, lorsque la platine 9 est fixée sur le support 6, le côté postérieur de cette platine 9 est appliqué contre une face de la peau (2 ; 2') du mur préfabriqué 1. Les moyens de guidage permettent, alors, de guider le mur préfabriqué 1 superposé qui vient, alors également, en applique contre le côté postérieur de cette platine 9, ceci de sorte que ces murs préfabriqués 1 se trouvent, alors avantageusement, alignés.In this regard, it will be noted that when the plate 9 is fixed on the support 6, the rear side of this plate 9 is applied against one face of the skin (2; 2 ') of the prefabricated wall 1. The guiding means allow then, to guide the prefabricated wall 1 superimposed that comes, then also, applies against the rear side of the plate 9, so that these prefabricated walls 1 are, then advantageously, aligned.

L'invention concerne, également, un mur préfabriqué 1, d'une part, présentant les caractéristiques décrites ci-dessus (en particulier au moins une peau 2 ; 2' réalisée en un matériau hydraulique) et, d'autre part, comportant au moins un dispositif de fixation 5 d'un garde-corps, ledit au moins un dispositif de fixation 5 présentant les caractéristiques décrites ci-dessus.The invention also relates to a prefabricated wall 1, on the one hand, having the characteristics described above (in particular at least one skin 2; 2 'made of a hydraulic material) and, on the other hand, comprising less a device 5 for fixing a railing, said at least one fastening device 5 having the characteristics described above.

En particulier, ledit au moins un dispositif de fixation 5 comporte ladite première aile 60 et ladite deuxième aile 61 du support 6 d'un tel dispositif de fixation 5.In particular, said at least one attachment device 5 comprises said first wing 60 and said second wing 61 of the support 6 of such a fixing device 5.

Dans ce mur préfabriqué 1, au moins une partie (de préférence l'intégralité) de la première aile 60 du support 6 d'un tel dispositif de fixation 5 s'étend à l'intérieur de la peau 2 du mur préfabriqué 1 (plus particulièrement lorsque celui-ci 1 comporte une unique peau 2) ou de l'une 2 des peaux (2 ; 2') du mur préfabriqué 1 (plus particulièrement la peau externe 2 de ce mur préfabriqué 1 lorsque celui-ci 1 comporte deux peaux 2 ; 2'), ceci selon un premier plan au moins parallèle au plan selon lequel s'étend cette peau 2.In this prefabricated wall 1, at least a part (preferably all) of the first flange 60 of the support 6 of such a fastening device 5 extends inside the skin 2 of the prefabricated wall 1 (plus particularly when the latter 1 comprises a single skin 2) or one 2 of the skins (2; 2 ') of the prefabricated wall 1 (more particularly the outer skin 2 of the prefabricated wall 1 when the latter 1 has two skins 2; 2 '), this in a first plane at least parallel to the plane along which this skin 2 extends.

On observera que ladite au moins une partie de la première aile 60 du support 6, s'étendant à l'intérieur d'une telle peau 2 du mur préfabriqué 1, est noyée à l'intérieur du matériau de cette peau 2 du mur préfabriqué 1.It will be observed that said at least part of the first flange 60 of the support 6, extending inside such a skin 2 of the prefabricated wall 1, is embedded inside the material of this skin 2 of the prefabricated wall. 1.

La deuxième aile 61 du support 6 d'un tel dispositif de fixation 5 s'étend latéralement et extérieurement par rapport à ce mur préfabriqué 1 ainsi que par rapport à la peau 2 de ce mur 1 à l'intérieur de laquelle 2 s'étend la première aile 60 du support 6 de ce dispositif de fixation 5, ceci selon un deuxième plan, d'une part, parallèle au plan selon lequel s'étend cette peau 2 et, d'autre part, s'étendant extérieurement par rapport à cette peau 2.The second wing 61 of the support 6 of such a fastening device 5 extends laterally and externally with respect to this prefabricated wall 1 as well as with respect to the skin 2 of this wall 1 inside which 2 extends the first flange 60 of the support 6 of this fixing device 5, this in a second plane, on the one hand, parallel to the plane along which this skin 2 extends and, on the other hand, extending outwardly with respect to this skin 2.
