Description

 The present invention relates to a device for transporting at least one prefabricated wall consisting of at least one concrete slab or the like.

This invention relates to the field of manufacturing devices designed to receive at least one prefabricated wall and to transport it between a manufacturing plant of such a wall and the site on which such a wall must be implanted.

Already known such transport devices comprising, in fact, a plate or the like on which are arranged in a vertical position, such walls.

It will be observed that such a tray may be provided with wheels and then adopt the form of a transport trailer suitable for connection to a tractor for its on-site routing. However, according to another type of embodiment, such a tray may also be designed to be associated with a frame, including that comprises a transport vehicle or a transport trailer to be connected to a tractor or the like. Such a chassis adopts substantially the shape of a "U" inside which are reversibly engaged the walls and / or said plate which is then secured to this frame to allow its displacement. It will be observed that such a transport device may, advantageously, include means capable of ensuring the lifting of the plate, in particular from the ground on which it rests, in order to bring it to an elevated position compatible with road transport.

Such a plate has, usually, a rectangular shape and comprises, at a lateral end, a vertical support for receiving means designed to maintain a wall in a vertical position, at least during its delivery on site .

Such holding means are in the form of a rod, engaged through said support, and having, on the one hand, a first portion extending on one side of this support and inside the prefabricated wall, between the two braced concrete plates constituting such a wall, and, on the other hand, a second portion extending on the other side of this support and in front of it.

In this respect, it will be observed that such a rod is of removable type and must, in order to maintain the wall in vertical position on the plate, be immobilized, on the one hand, with respect to this wall and, on the other hand, compared to its support.

To do this, such a rod is completed by a first wedge, in particular of metal type, engaged in an eyelet that has the second portion of this rod and abuts against said support, this, in particular to prevent this rod completely crosses this support and falls inside the wall.

This rod is, furthermore, completed by a second wedge, wedge-shaped, in particular made of wood, engaged inside the wall and interposed between a first wall of the wall and the rod, which can either be in abutment against a second wall of the wall, or cooperate with a third wedge interposed between the second wall wall and the rod, or be free on the side of the second wall. It will be observed that the placement of these holds (more particularly the second block) is in force, in particular with the aid of a hammer. This implementation has disadvantages consisting, in particular, in that it requires the use of a tool and in that it proves to be difficult because of, on the one hand, the difficulty to engage such a wedge inside the wall, especially in the presence of the support and a first wedge, on the other hand, the accessibility of such a wedge to hit it with a hammer, while avoiding to cause problems. damage to the wall. In addition, when it is a matter of removing such a wall from its plate, it is first necessary to unblock at least one of the wedges, which requires the intervention of an operator, the use of a tool, and the application of consistent efforts, all of which combined with the aforementioned accessibility issues. In view of the difficulties encountered by such an operator in removing such a wedge, the latter is usually content to remove only the second wedge positioned inside the wall when it is not content merely to push it back to the wall. inside the wall, while leaving in place the rod and the first shim associated therewith.

In this regard, it will be recalled that the rod extends inside the wall and is then likely to be positioned above a spacer connecting the two walls of the wall. Also, when it comes to removing the wall of the plate with a lifting device, it is essential to give the wall, first, a horizontal movement to avoid a collision between a such rod and a spacer and then an upward vertical movement. It also happens that the operator is not able to remove the second shim and proceeds, then, only to the removal of the first shim leaving in place the rod and the second shim.

In this case, it is, again, essential to confer on the wall, first of all, a horizontal displacement so as to allow withdrawal of the rod from its support and then an upward vertical movement.

The multiplication of these movements and / or the need for a strictly horizontal movement, on the one hand, for which the lifting gear is usually poorly adapted and, on the other hand, during which the wall is likely to rub or hanging the tray at risk of damage, constitute a major drawback in the unloading process of a transport device. In addition, the rods and / or the second shims remaining in place on the wall are all likely objects, during the handling of the wall, to fall from the wall on an individual and cause him injuries which is unacceptable . Finally, it will be observed that the rods and the wedges are of the removable type and are in no way fixed permanently on the support. That being so, these stems and wedges are likely to be removed from the support or fall from the wall (or this support) and, thus, end up in a place on the site where they are forgotten, which happens, in fact , for a quarter of this type of material.

The present invention aims to overcome the disadvantages of the prior art transport devices.

In this connection, the invention relates to a device for transporting at least one prefabricated wall consisting of at least one concrete slab or the like, this device comprising, on the one hand, a means for receiving at least one such a wall in a vertical position and, secondly, at least one means for maintaining such a wall in such a vertical position, characterized in that the means for maintaining the wall in the vertical position is constituted by at least one means of support adapted to cooperate with an outer side wall of a plate of the wall for lateral support thereof.

According to another characteristic, this device comprises, in fact, two vertical wall holding means arranged on either side of this wall and each constituted by a support means designed to cooperate with an external lateral wall. a plate of this wall and between which is pinched this wall.

According to the invention, the support means is constituted by an element extending over at least part of the height of the wall and defining at least one plane support surface intended to come into contact with an external lateral wall of a wall .

More specifically, such an element may be constituted by a flat plate or the like, more particularly of the removable type, in particular provided with cutouts.

According to an additional feature, the transport device comprises means for moving the support means on this device.

In addition, this device comprises means for reversibly immobilizing the support means in a specific holding position. Another feature is that the means for receiving at least one wall is constituted by a frame made by assembling profiles, in particular tubular, more particularly of metal type. Finally, said device comprises a vertical support, on the one hand, implanted at a lateral end of the means for receiving a wall and, on the other hand, which are secured to the one or more holding means in a vertical position. from this wall. The advantages of the present invention consist in that the means for maintaining the wall in a vertical position is positioned outside this wall and at the outer face of a wall of this wall, which, on the one hand, facilitates its accessibility and secondly, allows to have two walls side by side being only separated by such a holding means. This holding means allows, then advantageously, to ensure the maintenance of these two walls at once and to avoid any degradation of one wall by the other, especially by friction.

In addition, such a holding means may be in the form of a thin flat plate which is not detrimental to the load capacity of a transport device according to the invention.

In addition, such a holding means, although of removable type, is secured, permanently, the device which avoids its introduction, removal and possibly loss.

An additional feature is that the device comprises displacement mounting means of such a holding means which advantageously allows an adjustment of its position relative to the wall wall to maintain.

Yet another feature is that these mounting means are supplemented by immobilizing means advantageously, after appropriate positioning to avoid any movement. Note that the device may comprise two holding means may be arranged, each on both sides of a wall and in contact, each with a side wall of the wall. Such holding means act, then, such a clamp ensuring the maintenance of the wall.

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. The understanding of this description will be facilitated by reference to the appended drawings in which:

- Figure 1 is an overall view, schematically and in perspective of the transport device according to one invention; Figure 2 is a schematic side view of the device shown in Figure 1 and corresponding to a detail of this device relating to a support receiving a plurality of holding means;

- Figure 3 is a schematic and detailed view of a holding means. The present invention relates to the field of manufacture of devices designed to receive at least one prefabricated wall and to transport it between a factory manufacturing such a wall and the site on which such a wall must be implanted. As can be seen in FIG. 1, such a device 1 is, more particularly, designed to transport at least one prefabricated wall 2 consisting of at least one concrete plate 3 or the like.

In this regard, it will be observed that if, in the remainder of the description and in the drawings, reference will be made, more particularly, to a particularly appropriate use of the invention for the transport of at least one prefabricated wall constituted by two plates 3, 3A parallel, spaced and interconnected by means of spacers embedded in the concrete of each of these plates 3, 3A, the present invention is not limited and will find, also, a application well suited in the context of transporting a wall consisting of a single plate.

Thus and as shown in FIG. 1, such a transport device 1 comprises at least one means 4 for receiving at least one such wall 2 in a vertical position.

In fact, such a receiving means 4 may, at least in part, be constituted by a frame 5 made by assembling (in particular by welding) sections 6, more particularly of metal type, in particular tubular, shaped "H", of "I", "T", "L", "U" or other.

Such a frame 5 may then comprise longitudinal profiles 6A and transverse profiles 6B, connecting said longitudinal profiles 6A, and implanted at least at the lateral ends 7A, 7B, of the frame 5, and even more preferably distributed , in particular on a regular basis, over the entire length of the chassis 5.

It will be observed that such a chassis 5 is designed to be associated with a transport vehicle or a transport trailer (not shown) which ensures, in fact, the lifting, or even the loading, of this chassis 5 for the purpose of moving it . To do this, said chassis 5 has means 8 designed to cooperate with gripping means (not shown) that comprise such a machine or such a trailer.

As can be seen in FIG. 1, such cooperation means 8 may consist of a groove, a groove or the like, of horizontal type and defined at the level of the longitudinal profiles 6A (more particularly in the form of "H") that the chassis 5. It is, more particularly, within such a groove or the like that engage the gripping means, or even that slide these gripping means during a moving maneuver of such a machine or of such a trailer with respect to such a frame 5, to ultimately exert an upward traction on the edges of such a groove or the like for the lifting of the frame 5. It will be observed that the prefabricated wall or walls 2 can , in fact, come to rest directly on the transverse profiles 6B chassis 5, or even (and preferably) on a decking (including wood) covering such profiles 6B.

Another embodiment not shown is that this or these walls 2 may, again, come to rest on at least one plate disposed in particular over such transverse profiles 6B (solution not shown).

As can be seen in FIGS. 1 and 2, said transport device 1 also comprises a support 9 implanted at a lateral end 7A of the frame 5, more particularly that 7A located at the top of the device 1, that is, say that 7A directed towards the tractor of a transport trailer or the cab of a transport vehicle likely to cooperate with such a device 1.

Such a support 9 may, again, be constituted by an assembly (particularly by welding) of profiles, in particular tubular, more particularly of metal type.

This support 9 is of vertical type and extends, in particular perpendicularly, from said frame 5 of which it is secured, in particular by interlocking (more particularly of the reversible type to allow disassembly of the support 9 for the purpose of a stack of a plurality of frames 5 for storage or transport) or by welding.

Another feature of the invention is that this transport device 1 further comprises at least one means 10 for holding a prefabricated wall 2 of the aforementioned type in a vertical position.

In this regard, it should be observed that such a holding means 10 can be used to maintain the wall 2 at an outer sidewall 12 thereof 2 while at 1 ' another external lateral wall 12A of this wall 2, the maintenance can be provided by another wall that receives the device 1.

However, and according to a preferred embodiment of

The invention visible Figure 1, the device 1 comprises, for each wall 2, two holding means 10; 10 'arranged on both sides of this wall 2 and employees, each, to ensure the maintaining this wall 2 at an external lateral wall 12;

12A of the latter 2.

According to the invention, such means 10; 10 'of maintaining in the vertical position of the wall 2 is constituted by at least one support means 11; 11 'adapted to cooperate with an outer side wall 12; 12A of a plate 3; 3A of this wall 2 for lateral support of the latter 2.

In fact, such a support means 11 is constituted by an element 13 extending over at least a portion of the height of the wall 2 and defining at least one flat bearing surface 14 intended to come into contact with a side wall external 12 of the wall 2.

In this respect, it should be observed that, as can be seen in FIG. 1, such an element 13 may be constituted by a wing 15 or the like extending, on the one hand, longitudinally with respect to the frame 5 and, d on the other hand, laterally relative to the support 9 of which such a wing 15 is made integral, in particular by welding. In fact, the device 1 according to the invention may comprise a plurality of these wings 15 implanted, in particular in a regular manner, at the level of at least one of the lateral uprights 16, 16A (preferably at the level of the two uprights 16, 16A ) that includes the support 9. Such a wing

15 is then implanted at a lateral end of the support 9 and may have a single flat bearing surface 14 intended to come into contact with an outer side wall 12 of a wall 2 disposed most externally on the frame 5, in particular at the edge thereof.

In fact, it is, more particularly, against such a support means 11 in the form of a wing 15 that an outer side wall 12 of an outer wall 2 will be pressed to bear on this means 11 , this during the loading of the transport device 1.

A particular embodiment not shown is that these wings 15 can be connected to each other by a plate (especially metal) located in the extension of these wings 15 and designed to increase the bearing surface 14.

However, and according to a preferred embodiment of the invention, such a support means 11 defines two planar bearing surfaces 14, 14A intended to come into contact, each with an outer lateral wall 12 of two juxtaposed walls 2.

Also and according to a preferred embodiment of the invention, said element 13 defining such a support means 1 is constituted by a flat plate 17 or the like, more particularly of the removable type, in particular made of a metallic material.

Such a plate has a small thickness, especially between 0.5 and 1.5mm. Such a thickness advantageously makes it possible to interpose such a plate 17 between two juxtaposed walls 2 while preserving the maximum loading capacity of the device 1.

It will be observed that such a plate 17 may be provided with cutouts 29 making it possible to lighten this plate 17, in particular with a view to facilitating its handling, more particularly its removal or its placement on the device 1.

Another feature is that such a plate 17 can be completed, at each of its bearing surfaces 14, 14A, by at least one protection means 28 of the wall 2 against which the plate 17 will bear. Such a protection means 28 may be constituted by at least one shim protection or the like (FIG. 3), in particular of rubber, or even by a coating (more particularly of rubber) applied (in particular by vulcanization) on at least a part of such a plate 17 (more particularly at its free end, especially over the entire height of the plate 17).

According to another characteristic of the invention, the device 1 comprises means 18 for mounting in displacement, on this device 1 (and, more particularly on the support 9 which this device 1 comprises), the support means 11, more particularly that adopting the form of an element 13 consisting of a flat plate 17 or the like.

Such means 18 for mounting in displacement advantageously allow a displacement of such a support means 11 so as to allow the positioning of such a support means 11 on the support 9 at a distance of one other support means 11 compatible with the reception of a wall 2 by fitting between these two support means 11, or even so as to allow such positioning after a wall 2 has been arranged on the frame 5, this of in order to make this support means 11 rest against a side wall 12 of such a wall 2.

It will be observed that such means 18 for mounting in displacement are constituted, on the one hand, by at least one rod 19; 19 'or the like equipping the support means 11; 11 '. In this regard, it will be observed that one embodiment of the invention consists in that a support means 11 is equipped with at least two rods 19, 19A implanted, preferably at each end of such a device. support means 11, or even and preferably at least a third rod 19B interposed between the two other rods 19, 19A (Figures 1 to 3).

On the other hand, such mounting means 18 are constituted by at least one slide 20, in particular horizontal, inside which at least one rod 19; 19 'of at least one support means 11; 11 'is slidably mounted. However, and as can be seen in the appended figures, the mounting means 18 preferably comprise, on the one hand, a plurality of parallel slides 20; 20A; 20B, in particular horizontal, and, secondly, a plurality of rods 19; 19A; 19B (19 '; 19'A; 19'B) fitted to the same bearing means 11 (11') and mounted, each (19, 19 '; 19A, 19'A; 19B, 19'B), in sliding inside such a slide 20; 20A; 20B.

A particular embodiment consists in that the number of slides 20 is greater than the number of rods 19 per holding member 13 which advantageously makes it possible to move such a holding member 13 vertically by relative to the support 9 to adapt to walls 2 which may have different heights.

Another feature is that behind the scenes

20; 20A; 20B and the rods 19; 19A; 19B of the same holding member 13 are regularly distributed at the level of the support

9 or the holding member 13 and are, in particular, implanted equidistant from each other.

In addition, the device 1 is arranged so that the rods

19 and the slides 20 are arranged in correspondence at the device 1, so as to allow their cooperation. Thus the distances between, on the one hand, the rods 19 and, on the other hand, the slides 20 are substantially identical. It will be observed that the device 1 comprises such a slide 20, 20A, 20B which is, in fact, implanted at the level of said support 9 and which can, as the case may be, be defined at a cross member 21 connected (in particular by welding) to the lateral uprights 16, 16A of the support 9 or, again (and preferably as visible in FIG. 2), be constituted by two crosspieces 21, 21 ', connected (in particular by welding) to the lateral uprights 16, 16A, and defining a light 22 of such a slide 20 within which 22 slides at least one rod 19.

In this connection, it should be observed that, to facilitate the sliding of such a rod 19 in a slide 20, this rod 19 is preferably coated (in particular by lining) with a material 23 having a low friction.

An additional feature is that the width of the slot 22 of a slider 20 and the diameter of the rod or rods 19 passing therethrough are dimensioned so as to allow tilting of the support means 11 relative to a vertical position maintaining a wall 2.

According to another characteristic of the invention, the device 1 comprises means 24 for reversibly immobilizing the support means 11 in a determined wall-holding position 2. In fact, this holding position corresponds, more particularly , to that in which support means 11 has been brought either to the recessed position of a wall 2 or to bear against an external lateral wall 12 of a wall 2 through a movement authorized by the presence of the mounting means 18 traveling above. According to a preferred embodiment of the invention, these immobilizing means 24 are constituted, on the one hand, by a thread 25 defined at the rod 19 and, on the other hand, by a bolt 26 engaged on this Thread 25 and intended to be manipulated to ensure a locking of the rod 19 in the slide 20.

In fact, such a bolt 26 is preferably located outside the slide 20 and in front of the support 9 in order to facilitate its handling.

Between this bolt 26 and this slide 20 may be interposed a washer 27 bearing against this slide 20.

Although the invention has been described with respect to a particular embodiment, it is understood that it is in no way limited and that various modifications of shapes, materials and combinations thereof can be made. various elements without departing from the scope and spirit of the invention.
