Description

Title of the invention: Device for fixing to a trellis in a slab

[0001] The invention relates to the technical field of devices for fixing ducts and / or tubes, more particularly to fixing devices used for fixing ducts and / or tubes in a concrete slab.

[0002] The invention also relates to a fixing system comprising several fixing devices connected to each other vertically and / or horizontally.

[0003] It is known in the prior art to fix a sheath and / or a tube to use a device in the form of a snap-fastening means comprising at least two branches made of elastically deformable material defining an annular shape provided with an opening intended to receive said sheath or said tube on one side and an anchoring pin in a wall or other means of retaining the fixing device on an opposite side.

[0004] Generally, the dowel is hollow and opens between the branches in order to receive a means of fixing, most of the time a fixing screw.

[0005] Thus, prior to fixing said sheaths and / or tubes, the operator must carry out a step of fixing the fixing device by means of a screw, which makes the method of fixing said sheaths and / or tubes long and tedious, particularly when numerous sheaths and / or tubes must be fixed.

[0006] In addition, such fixing devices require the use of too many fixing elements such as screws or tools necessary for said fixing such as hammers or other necessary tools.

[0007] Furthermore, these devices are not modular and can hardly be aligned to facilitate their placement end to end in order to cover large surfaces.

[0008] In the same way, it is not possible to be able to accumulate several levels of sheaths and / or tubes on the same surface. Indeed, once fixed against a wall, the device takes up a surface on which no other fixing device can be positioned, making their use difficult.

[0009] Furthermore, once fixed, the fixing devices of the prior art are difficult to remove, which is necessary if the operator has to modify the position of the device, for example following a positioning error.

[0010] The invention therefore falls within this context and seeks to meet all of the aforementioned needs while resolving all of the aforementioned drawbacks.

[0011] Thus, the invention seeks to propose a device for fixing sheaths and / or tubes that are easy to use, modular, also allowing a large surface area to be covered, reliable, and also inexpensive, in particular by reducing the number of parts required and reducing the time for fixing said sheaths and / or tubes, all while being adaptable.

[0012] Indeed, the invention also makes it possible to adapt to all the needs of operators on site, whether in length or height of the positioning of said sheaths and / or tubes or their diameters. Presentation of the invention

[0013] The subject of the invention is a fixing device which is easy to use, adaptable, modular, inexpensive and reliable.

[0014] To this end, according to the invention, a modular fixing device has been developed comprising a support comprising a first face and a second face, at least one first fixing means arranged on the first face of the support extending in a first direction, at least one second fixing means arranged on the second face of the support extending in a second direction opposite to the first direction, at least one first connecting means arranged on a free end of the support and at least one second connecting means arranged on the first face of the support extending in the first direction, said second face of the support comprising an element for complementing the second connecting means.

[0015] It is then understood, according to the invention, that the fixing device is adjustable in length with the presence of the first connecting means arranged on the free ends of the support in order to fix the fixing devices to each other, but also in height with the second connecting means intended to be fixed with the complementary element arranged on the second face of the support.

[0016] Thus, it is easy for the operator to add and / or remove a fixing device depending on the desired length or height, all without requiring a definitive fixing operation of said fixing device before positioning the sheaths and / or tubes.

[0017] Indeed, the second fixing means arranged opposite the first fixing means is intended to be fixed, preferably to a trellis in a reversible manner in order to facilitate its positioning.

[0018] In the same way, it is understood that the first fixing means is different from the second connecting means and is therefore intended to receive said sheaths and / or tubes in order to form networks, for example water or electricity.

[0019] Preferably, the support of the fixing device extends in a longitudinal direction of the fixing device according to the invention.

[0020] Furthermore, the fixing device according to the invention is more suitable for being arranged at against a trellis intended to be positioned in a slab, particularly in concrete, in order to be able to form water or electricity networks inside the concrete slab.

[0021] Preferably, the first fixing means comprises at least two branches made of elastically deformable material defining a U shape, said branches comprise on their free end at least one flap curved towards the center of the first fixing means.

[0022] It is thus understood that the sheaths and / or tubes are intended to be slid into the first fixing means, more particularly between the two branches against the flaps in order to position and hold the sheaths and / or tubes in position.

[0023] Advantageously, the first fixing means make it possible to adapt to several diameters of the sheaths and / or tubes, while making it possible to maintain said sheaths and / or tubes in position with the presence of the flaps. Indeed, the fact that the branches of the first fixing means are made of elastically deformable material allows the latter to be able to adapt to different diameters of sheaths and / or tubes.

[0024] Preferably, the branches of the first fixing means define a space intended to receive the sheaths and / or tubes which extend in a transverse direction of the fixing device.

[0025] Thus, it is understood that the support and the space of the branches of the first fixing means extend along substantially perpendicular planes.

[0026] In a preferred embodiment, the second fixing means comprises at least two branches made of plastically deformable material and capable of being moved apart or brought together, each branch defining a half-opening, respectively intended to grip a fixing element.

[0027] It is thus understood that the branches of the second fixing means extend in the second direction, opposite to the first and define a clamp intended to grip the fixing element.

[0028] Preferably, the fixing element is a tube of a trellis intended to be arranged in a concrete slab.

[0029] In a particular embodiment, and in order to facilitate the separation and bringing together operations, the branches of the second fixing means comprise at least one gripping element arranged on each of the free ends of the branches of said second fixing means.

[0030] In a particular embodiment, and in order to facilitate the use of the fixing device, the branches of the second fixing means comprise a base fixed to the second face of the support comprising a height greater than that of the fixing element.

[0031] In a particular embodiment, the branches of the second fixing means define a space in which a fixing element is intended to be fixed, said space extending in a longitudinal direction of the fixing device.

[0032] Thus, it is understood that the support and the space of the branches of the second fixing means extend along substantially parallel planes.

[0033] In a particular embodiment, the branches of the second fixing means are arranged opposite each other.

[0034] In another embodiment, and in order to extend the contact surface between a fixing element and the branches of the second fixing means, the branches of the second fixing means are arranged next to each other.

[0035] In a preferred embodiment, the first connecting means comprises a male type fixing means on one free end and a female type fixing means on the other free end.

[0036] It is understood that the fixing device comprises on each of its free ends a first connecting means in order to allow the different fixing devices to be connected together along the length.

[0037] Preferably, the female part of the first connecting means is in the form of a groove into which the male part of the first connecting means, in the form of a projecting element, is intended to slide inside.

[0038] More particularly, the female part of the first connecting means is in the form of a hollow cylinder in which is arranged a slot into which the male part in the form of a cylinder slides.

[0039] In a preferred embodiment, the second connecting means comprises at least two rods, made of elastically deformable material, each provided on its free end with a wedging means.

[0040] It is understood that the rods extend in the same direction as the first fixing means and make it possible to fix another fixing device on a height of the fixing device in order to form levels of fixing devices and consequently of sheaths and / or tubes.

[0041] Preferably, the wedging means are in the form of a heel key intended to clip against the edges of the retention element.

[0042] In a preferred embodiment, the second connecting means extends to a height greater than that of the first fixing means.

[0043] Preferably, the first fixing means are spaced apart by a predetermined distance.

[0044] Thus, the sheaths and / or tubes are spaced apart by a predetermined distance, namely the distance separating two first fixing means.

[0045] In a particular embodiment, the predetermined distance is similar on the entire fixing device.

[0046] In another embodiment, the predetermined distance is different from one first fixing means to the other.

[0047] In a preferred embodiment, and in order to reduce production and usage costs, the entire fixing device is a single piece.

[0048] The invention also relates to a fixing system comprising at least two fixing devices according to the invention.

[0049] In a particular embodiment, the system comprises at least two fixing devices connected to each other by the first connecting means and / or by the second connecting means.

[0050] The invention also relates to a slab, preferably made of concrete, comprising at least one trellis and at least two fixing devices according to the invention.

[0051] Other advantages and characteristics of the present invention are now described with the aid of examples which are purely illustrative and in no way limitative of the scope of the invention, and from the appended drawings, drawings in which the various figures represent:

[0052] [Fig-1] is a schematic representation seen from the front of the fixing device according to the invention.

[0053] [Fig.2] is a schematic perspective representation of the second means of fixing the fixing device.

[0054] [Fig.3] is a schematic representation, front view, of the fixing system of the sheaths and / or tubes comprising at least two fixing devices according to the invention.

[0055] For reasons of simplicity and clarity of illustration, the elements represented in the figures have not necessarily been produced to scale. Thus, the dimensions and relative proportions of certain elements may be exaggerated or even attenuated.

[0056] In the following description, elements that are identical, by structure or by function, appearing in different figures retain, unless otherwise specified, the same references.

[0057] It should be noted that in these figures the structural and / or functional elements common to the different variants may have the same references.

[0058] Of course, various other modifications may be made to the invention within the scope of the appended claims.

[0059] With reference to [Fig.l] to [Fig.3], the invention relates to a device 1 for fixing sheaths and / or tubes 8 which is easy to use, modular and inexpensive, comprising a support 2 having a first face 21 and a second face 22 opposite the first face 21.

[0060] In order to fix sheaths and / or tubes 8, the support 2 of the fixing device 1 comprises on its first face 21 first fixing means 3 extending in a first direction.

[0061] The first fixing means 3 comprise two branches 31, made of elastically deformable material, defining a U shape, said branches 31 comprise on their free end at least one flap 32 curved towards the center of the first fixing means 3.

[0062] In addition, the first fixing means 3 are spaced apart by a predetermined distance in order to optimize the structuring and location of the sheaths and / or tubes 8 intended to slide into the first fixing means 3.

[0063] The support 2 comprises on its second face 22 second fixing means 4 extending in a second direction opposite to the first, so as to fix said fixing device 1 against a fixing element 7 against which said fixing device 1 is fixed.

[0064] As illustrated in [Fig.2], the second fixing means 4 comprise two branches 41, made of deformable plastic material, capable of being separated or brought together, each branch 41 defining a half-opening 42, respectively intended to grip the fixing element 7.

[0065] In addition, and in order to facilitate the separation and bringing together operations, the branches 42 of the second fixing means 4 comprise at least one gripping element 43 arranged on each of the free ends of the branches 42 of said second fixing means 4.

[0066] The two branches 42 of the second fixing means 4 are arranged next to each other in order to extend the contact surface between the fixing element 7 and the branches 42 of the second fixing means 4, which makes it possible to improve the fixing of the fixing device 1 to the fixing element 7.

[0067] In order to make the fixing device 1 modular, said fixing device 1 comprises on the free ends of the support 2 first connecting means 5, said first connecting means 5 comprise on one free end of the support 2 a male type fixing means 51 and on its other free end a female type fixing means 52.

[0068] In the same way, and in order to produce stages of ducts and / or tubes 8, said fixing device 1 comprises on the first face 21 of the support 2 second connecting means 6 extending in the first direction.

[0069] The second connecting means 6 comprise two rods 61, made of elastically deformable material, each provided on its free end with a wedging means 62, intended to be fixed to a retention element 23 arranged in the second face 22 of the support 2.

[0070] The rods 61 comprise a height greater than that of the branches 31 of the first fixing means 3, so as not to hinder the positioning of a second fixing device 1 on a first fixing device 1 to create said stages of ducts and / or tubes 8.

[0071] In order to reduce costs, the fixing device 1 is a single-piece device.

[0072] As illustrated in [Fig.3], the invention also relates to a fixing system 10 comprising fixing devices 1 fixed to each other by their first 5 and their second connecting means 6.

[0073] In any event, the invention cannot be limited to the embodiments specifically described in this document, and extends in particular to all equivalent means and to any technically effective combination of these means.
