ASSEMBLY OF STRUCTURAL ELEMENTS FOR FORMING A

FLOOR PARKING WITH FLOORS, AND FLOOR PARKING WITH FLOORS

CORRESPONDING

The present invention relates to the field of multi-storey overhead car parks, and relates more particularly to such a car park of modular design.

In order to meet the need for parking facilities which are quick to install, multi-storey overhead parking lots have been proposed, formed by prefabricated modules which are assembled together on the site of the parking facility. Such modularity also makes it possible to enhance existing installations, by installing the modules to constitute one or more additional floors, as well as to obtain, using dismountable assembly means between the modules, a parking space which is itself removable, thus meeting the need for temporary parking facilities.

An example of such a modular parking lot is described in French patent application FR 2 642 784 A1, and generally comprises deck modules, posts and assembly brackets. More particularly, each deck module is formed of a rectangular metal frame composed of generally I-shaped profiles, in any event of the profiles having a bottom flange, and of a floor element covering the chassis and intended to form the deck. one floor of the car park once the installation of the latter is complete. Each deck module is handled by lifting means so as to come to rest, at each of its four corners, on a post, by plane support between said lower flanges and the upper end surfaces of the posts, posts to which the module deck is assembled by bolting via said brackets, so that each deck module is linked by embedding to the posts in order to allow the transmission to the posts of the weight and the forces applied to the deck modules.

Although the principle underlying this solution is satisfactory, assembling the different modules remains a tedious and time consuming operation due to the large number of bolts that must be put in place in order to definitively ensure the connection between the deck module and poles. The disadvantage is that as long as this embedding connection is not permanently ensured, the deck module remains held in position using the lifting means, and it is easily understood that this presents a risk from the point of view of the safety of the operator (s) providing bolting, in addition to mobilizing the lifting means during bolting.

The present invention thus aims to propose a solution for quickly and easily assembling different modules of an aerial parkinq with stalls while

improving the security of operators ensuring The assembly. The present invention has thus for object a

set of structural elements intended to be assembled to form an aerial parkinq at least one step, said structural elements comprising deck modules, called supported modules, which are substantially rectangular and arranged to, in the assembled position, form at least part of the deck of an overhead park stage, and posts arranged to support the modules supported in the assembled position, said set of structural elements being characterized in that each supported module comprises, at each of its two ends longitudinally opposite, at least one housing open at one end and capable of receiving a head of a pole, and support means capable of coming to bear on a respective pole after threading the housings on the heads of the poles so that the supported module is stably supported by poles.

Thus, according to the present invention, it suffices simply, with the aid of lifting means, to place the supported module on the posts so that the supported module is supported stably, without any other additional operation, and in particular before the final installation between the deck module and the posts is ensured. The operator (s) ensuring said final embedding will not work on a deck module whose stability is ensured only by lifting means, and the lifting means may be used to handle another supported module while the operator (s) on the ground ensure the final installation of the supported module which has just been installed. One can even envisage that the defined embedding is carried out after the assembly of the whole of the deck.

This final installation can be ensured by any appropriate means, in particular by bolting. One could provide a permanent embedding by bolting using brackets as in the prior art, but preferably one will make integral with one another a flange of the supported module and a flange of the post as described below.

According to a preferred embodiment, each supported module comprises two housings at each of its two longitudinally opposite ends.

Provision could be made for the support means of each supported module to be formed by the bottom of each housing, which bottom will then be flat and will come to bear on the free upper end surface of the head of the respective post.

However, preferably:

- Each post has a flange arranged to serve as a support for a lower surface of a supported module, which lower surface forms, in whole or in part, said support means;

- each supported module housing has, at its bottom, either at least one male centering element, or at least one female centering element, while each post has at its free end, respectively, or at least one female centering element , or at least one male centering element, the or each male centering element being arranged to be received in a respective female centering element; and

- The heads of the posts and the housings are dimensioned so that after threading the housings on the posts is present between the or each male centering element and the respective female centering element a first clearance greater than a clearance present between the other parts of the housing and of the head of the post, the first set being defined to allow a transmission of the forces between the supported module and the post via the male centering element (s) and the female centering element (s).

Still in this preferred embodiment, there can be provided, for each supported module housing and each post, a single male centering element and a single female centering element, both aligned on the longitudinal axis of the post.

Preferably, the head of each post ends in a frustoconical part to more easily thread a module housing supported on said head.

Preferably, each post comprises a tube which is filled with concrete and which carries, where appropriate, the flange, a part of the concrete projecting beyond one end and forming with the latter the head of the upper tube,

post, with the optionally the or the elements of male centering or the or the elements of female centering which are worn by the tube and who are protruding of said part of concrete itself in projection of the tube. Of

this way, are transmitted between the forces which module supported and the post, are it via the tube, and not concrete.

The set of structural elements according to the present deck, invention may further comprise modules of said suspended modules, intended to be placed each between two adjacent supported modules, so as to form with the supported modules the deck of a storey parking lot, the suspended modules and the supported modules having suspension means for suspending the suspended means from the adjacent supported modules.

Preferably, the suspension means are attachment means comprising:

- for each supported module, two pairs of hooks, one pair on each longitudinal side of the supported module and the hooks of the same pair being spaced from each other, preferably each at one of the longitudinally opposite ends of the supported module, the hooks projecting outwardly from said longitudinal side, the hooks each having an opening directed upwards and a cylindrical bottom whose axis is parallel to the longitudinal direction of the supported module, the axes of the cylindrical bottoms hooks of the same pair being aligned; and for each suspended module, two pairs of pivots, one pair on each longitudinal side of the suspended module and the pivots of the same pair being spaced by the same distance from which the hooks of a same pair are spaced, the pivots being dimensioned and positioned to be suitable for each to bear on the cylindrical bottom of a respective hook, preferably by forming with the respective hook a pivot connection.

Such a configuration of the suspension means makes it possible to authorize a misalignment of the upper plane of the different modules, which could be due to misalignment of the supports of the posts on the ground.

Each supported module, and optionally each suspended module, can comprise a metal frame and a floor part, preferably formed by a collaborating floor, which rests on the metal frame, the housing (s), and possibly the suspension means, being carried by the chassis of the supported modules and, if necessary, the chassis of the suspended modules.

In the case of the use of a collaborating floor and of a post comprising a tube filled with the advantages provided by the use of a metal structure (prefabrication in the factory of the modules, concrete weight as described above, the parking obtained will have a light, rapid assembly on site, absence of foundations, flexibility in the arrangement of the structure, ability to adapt to the configuration of the installation site) and the advantages provided by concrete, in particular its fire resistance.

It is emphasized here that the configuration described above, with flange and element (s) of male / female centering (s) makes it possible both to ensure a quasi-continuity of the concrete of the post with the concrete of the collaborating floor and a transmission of the forces between the post and the deck module. Thus, in the event of a fire, the stability of the entire car park remains ensured even if the means ensuring permanent embedding no longer have any effectiveness, since they are not protected from fire. This prevents the parking lot from collapsing in the event of a fire.

In addition, it can be seen that the means described above allow a removable connection between the various structural elements, with disassembly just as easy, by simply lifting the modules supported from the posts and modules suspended from the supported modules.

The present invention also relates to an air car park comprising at least one floor, characterized in that it is formed by a set of structural elements as defined above.

It is emphasized here that the principle of suspending modules between modules supported by posts is not limited to a support of the modules supported in the manner described above. In other words, the suspended modules described above could be used with modules which are supported by poles in accordance with the prior art, namely resting, at each of their four corners, on a pole, by plane support between the lower flanges of the supported module and the upper end surfaces of the posts, with permanent embedding carried out while the module is still held by lifting means. However, these supported modules will be modified to present suspension means

Thus, there is also disclosed herein a set of structural elements intended to be assembled to form an overhead parking lot with at least one storey, said structural elements comprising deck modules, called supported modules, which are arranged to, in assembled position, forming at least part of the deck of a storey in the overhead parking area, and posts arranged to support the modules supported in the assembled position, said set of structural elements being characterized in that it further comprises deck modules, called suspended modules, each intended to be placed between two adjacent supported modules, so as to form, with the supported modules, the deck of an overhead parking space, the suspended modules and the supported modules having suspension means for suspend the means suspended from the adjacent supported modules. The suspension means, the supported modules and the posts can be as described above, and in particular the suspension means can be said attachment means.

Also disclosed herein is an overhead parking lot comprising at least one floor, characterized in that it is formed by such a set of structural elements.

To better illustrate the object of the present invention, there will be described below, by way of indication and not limitation, a particular embodiment with reference to the accompanying drawing.

reference 1, intended to form part of an apron of a

If we refer first to Figures 1 and

2, we can see that a part of a so-called supported deck module has been shown there, designated by the number of π

floor of an air parking lot in accordance with a particular embodiment of the present invention.

The supported module 1 comprises a metal chassis 2, shown alone in Figures 1 and 2, and a floor part fixed to the chassis 2 and having a substantially planar upper surface on which vehicles will circulate and be parked. The present invention is not specific to the part advantageously a floor 2a, visible in the appropriate figure on the chassis 2.

The chassis 2 is re joists 3 parallel and is: limited to a floor configuration, which will be collaborating including the steel tank

6 is fixed by any triangular means and formed by two extending in the longitudinal direction of the chassis 2, and two edge beams 4 each connecting two ends of the joists 3. The joists 3 are assembled to the edge beams 4 by any appropriate means, in particular by bolting a plate secured to the joist 3 to a plate secured to the edge beam 4. The joists 3 may be profiles IPN, IPE or PRS for example.

The chassis 2 thus has a mean plane, a longitudinal direction and a transverse direction, which will be substantially horizontal in the assembled position.

Such a chassis 2 is in itself conventional.

The chassis 2 is remarkable in that each edge beam 4 comprises two housings 5 and two attachment parts 6.

If we also refer to Figures 7 and 8, we can see that each edge beam 4 is formed by an upper wing 4a and a lower wing 4b horizontal, parallel to each other and connected to each other by two cylindrical 4c tubes, a central 4d core and two plates

4th side.

The two tubes

4c each form a housing 5.

The tubes 4c are spaced 1 from each other in the longitudinal direction of the edge beam 4, with a spacing corresponding overall to the spacing between the two joists 3, or greater or less than this.

The tubes

4c are vertical, and thus have an axis perpendicular to the mean plane of the chassis 2. The lower wing 4b has a circular annular region 4k surrounding each tube 4c and in which are provided through holes (not shown) whose function will be explained below. -after.

The lower end of each tube 4c is open, and thus opens onto the outside, a corresponding opening being provided in the lower wing 4b. The upper end of each tube 4c is closed by the upper wing 4a, the latter forming a bottom of the housing 5. This bottom is however only partially closed, because a circular hole 4f is provided in the upper wing 4a and whose the center is on the axis of the tube

4c. A cylindrical tubular part 4g (female centering element) open at its two ends, the axis of which is aligned with the axis of the tube 4c, extends upwards from the upper surface of the upper wing 4a. Thus, the tube 4c and the tubular part 4g communicate with each other via the hole 4f, the diameter of the tubular part 4g being equal to that of the hole 4f but less than that of the tube 4c. The function of the hole 4f and of the tubular part 4g will be explained in more detail below.

The 4d core is perpendicular to the upper wings

4a and lower 4b and extends from one tube 4c to the other tube

4c.

The core 4d is located on the longitudinal axis of the edge beam 4 and is in contact with the wings 4a and 4b and the tubes 4c, to which it is fixed by any suitable means, such as for example by welding.

The side plates 4e are also perpendicular to the upper wings 4a and lower 4b and located on the longitudinal axis of the edge beam 4, but they each extend outwards from a tube 4c. Again, the side plates 4e are fixed to the wings 4a and 4b and to the respective tube 4c by any suitable means, such as for example by welding.

Each side plate 4e thus has a free outer edge 4h, and this outer edge 4h is shaped to present a hook 4i, the opening of which is directed upwards and perpendicular to the mean plane of the chassis 2, and the bottom of which is cylindrical. The function of the hook 4i will be explained in more detail below. It is emphasized here that the end of the upper wing 4a is offset inwards relative to the end of the lower wing 4b, so that an edge region, including the hook 4i, is located beyond the end of the upper wing 4a.

The supported module 1 is a prefabricated element intended to rest on two pairs of posts 7, one of which is shown in FIG. 3. Each post 7 has a foot, by which it will rest on a floor in the assembled position, and a head 7a, by which it will cooperate with a supported module 1.

In the embodiment illustrated in the

Figures, and as can best be seen in Figures 3 to

5, the post 7 comprises a cylindrical tube 8, open at its two ends and intended to be filled with concrete, in particular reinforced concrete, and a base 9. The base 9 comprises a flat base 9a (or “pad”), intended to rest on a floor, from which extends a cylindrical housing 9b dimensioned to receive the lower end region of the tube 8 once the latter filled with concrete.

The upper end region of the tube 8 has a circumferential flange 8a which has an upper surface 8b perpendicular to the longitudinal axis of the tube 8, hereinafter simply designated by the "axis" of the tube 8 or of the post 7.

It can be seen that FIGS. 4 and 5 show bolts B, which pass through through holes (not visible) provided for this purpose in the flange 8a, and which in practice serve to bolt the flange 8 to the annular region 4k of the edge beam 4 to ensure the permanent embedding between the post 7 and the supported module 1. For reasons of clarity, these bolts B are not shown in FIGS. 7 and 8.

The upper end of the tube 8 is open, from which extend two vertical plates 8c intersecting perpendicularly at the axis of the tube 8 and carrying a centering pin 8d (male centering element).

In particular, a plate 8c has a vertical notch which opens onto the upper edge of the plate 8c and through which the second plate 8c extends. Each plate 8c has two vertical edges 8e which are in the lower part fixed to the inner wall of the tube 8 and which are in the upper part, projecting from the tube 8, inclined towards the axis of the tube 8.

The centering pin 8d is a piece comprising a cylindrical part 8f which is received in a notch 8g provided for this purpose in each of the plates 8c, by which the centering pin 8d is fixed to the plate 8c by any suitable means, such as by example by welding. The piece forming the centering pin 8d also includes a point part 8h extending from the end

upper part cylindrical 8f, at know beyond 5 of the plates 8c. As indicated above, of concrete 10, preferably concrete armed, is sunk at inside the tube 8, as we can see Figures 7 and 8. The

part of the concrete 10 protruding from the tube 8 is shaped to end in a truncated cone whose outer surface is flush with the inclined edges 8e.

The post 7 is a prefabricated element.

In the example illustrated in FIGS. 3 and 5, the two posts 7 of the same pair are connected by two crosspieces 11, in the upper part and in the lower part of the posts 7, in order to improve the rigidity of the assembly. . Of course, other stiffening means, such as for example a cross, can be provided. It is emphasized that it is also possible not to provide such stiffening means.

If we now refer more particularly to Figures 6 to 8, we can see that there is shown a supported module 1 in the assembled position on two pairs of posts 7, in particular that the supported module 1 is supported at each edge beam 4 by one

pair of posts 7. According to the present invention, each accommodation 5 is strung on the head of a post 7 respective. In this effect: - the diameter interior of the accommodation 5 is at least

so that the latter easily enters the interior of the housing 5, which entry is further facilitated by slightly greater than that of the head 7a of the post 7, the frustoconical shape given to the head 7a and which will guide said entry;

the distance, along the axis of the post 7, between the upper surface 8b of the flange 8a and the upper end surface of the concrete 10 of the post 7 is substantially equal to the distance, always along the said axis, between the lower surface of the lower wing 4b and the bottom of the housing 5, so that in the assembled position the supported module 1 is supported both on the flange 8a and on the post 7; and

- The diameter of the centering pin 8d, in particular of the cylindrical part 8f, is slightly less than the diameter of the hole 4f of the upper wing 4a, and therefore the internal diameter of the tubular part 4g, so that a portion of the cylindrical part 8f and the pointed part 8h extend into the tubular part 4 passing through said hole 4f.

There will be between the centering pin 8d and the tubular part 4f a clearance that is sufficiently small that the forces applied to the supported module 1 are transmitted to the post 7, in particular from the tubular part 4f to the centering pin 8d, before the supported module 1 has not moved relative to the post 7 in an inadmissible manner.

It can therefore be seen that, strictly speaking, each head 7a of the post 7 is connected to a housing 5 of the edge beam 4 with the only degree of freedom being a rotation about the axis of the post 7. It will be readily understood that after the supported module 1 is threaded onto the two posts 7, this degree of freedom is blocked due to the combination of the two pivot connections between each post 7 and the respective housing 5, so that the forces applied to the supported module 1 can effectively be taken up by the posts 7 via each edge beam 4.

It will also be readily understood that this stable connection is obtained automatically by simply threading the edge beam 4 onto the pair of posts 7, without any other operation to be carried out by an operator: the stability of the connection is ensured as soon as the module supported 1 is supported on the posts 7, since the centering pin 8d is simultaneously placed in the tubular part 4f. The bolts B can then be used to ensure the final embedding between the posts 7 and the supported modules 1.

According to the particular embodiment illustrated in the drawings, the deck of a storey in the air car park is also formed by so-called suspended deck modules, designated by the reference numeral 12, intended to be placed each between two supported modules 1 and to be hung from them as illustrated in Figure il. If we refer to Figure 9, we can see that there is shown a part of a suspended module 12.

The suspended module 12 differs from the module supported 1 mainly by the structure of the edge beams. Thus, the suspended module 12 also comprises a metal frame 13, shown alone in FIGS. 9 and 10, and a floor part fixed thereto and which can for example be formed by a collaborating floor of which only the steel tank 13a is shown in Figure 11.

The frame 13 is rectangular, at least the same dimension as the frame 2 in the longitudinal direction, and formed by two joists 14 and two edge beams 15.

Each edge beam 15 has an I-shaped profile over most of its length, with an upper wing 15a and a lower wing 15b connected by a core 15c. Blade

15c extends between two plates 15d perpendicular to the longitudinal axis of the edge beam 15, each located near a respective end of the edge beam 15 and fixed by any suitable means, such as by welding, wings 15a, 15b and core 15c.

Two plates 15e, parallel to each other and to the core 15c, extend from the face of each plate 15d opposite to that fixed to the core 15c.

These two plates 15e are spaced from each other with a spacing at least slightly greater than the thickness of the side plate 4e of an edge beam 4 of a supported module 1.

Furthermore, each plate 15e further comprises a circular through hole 15f aligned with the through hole 15f of the opposite plate 15e.

In addition, each plate 15e has a free edge 15g which extends perpendicular to the upper wing 15a and from one end of the latter, up to the vicinity of the lower wing 15b to which it is connected by a rounded part, the end of the lower wing 15b being slightly offset inwards relative to the end of the upper wing 15a. Thus, the free edge region 15g of each plate 15e, including

the hole crossing Respective 15f, is beyond of the end of the lower wing 15b. If 1 ' we no longer refers particularly to the Figures 12 and 13, we can see that each end of

each edge beam 15 of a suspended module 12 is connected by a pivot connection to a side plate 4e of an edge beam 4 of a supported module 1, and that this pivot connection is obtained by hooking, in the hook 4i of the side plate 4e, of a pivot 16 fixedly mounted in the two through holes 15f of the plates 15e. In particular, the pivot 16 extends parallel to the axis of the cylindrical bottom of the hook 4i and the diameter of the pivot 16 is chosen so that the pivot 16 can be introduced into the hook 4i, passing through the opening of the latter , until it comes to rest on the bottom of the hook 4i while being able to rotate relative to the latter.

Again, the pivotal connections between the suspended module 12 and the two adjacent supported modules 1 are obtained automatically: after said two supported modules 1 have been assembled on posts 7, the suspended module 12 is handled to be placed above the space between said two supported modules 1, then is lowered, each pair of side plates 15e of the suspended module 12 being threaded around a respective side plate 4e of a supported module 1, which is possible due to the offset between the upper wings 4a and 15a and the lower wings 4b and 15b of the edge beams 4 and 15. Once the pivots 16 bear in the hooks 4i, the suspended module 12 is released by the

means Handling, and East so hanging from his four corners. We aknowledge so than operators have not to

perform additional operations, such as bolting, for the assembly of the suspended modules.

The advantage of providing that the pivots 16 can additionally rotate in the respective hooks 4i, is that this allows the suspended module 12 to pivot relative to the supported module 1 at least slightly around an axis of rotation formed by the two pivots 16 located on the same longitudinal side of the suspended module 12, which allows a misalignment of the upper plane of the deck modules, as indicated above, while ensuring the transmission of forces between the modules supported 1 and suspended modules 12.

If we now refer to the

Figure 14, we can see that there is shown schematically an example of an air parking one floor mounted

Using the prefabricated modules and 12 and the posts described above.

car park

The aerial principle according to the present basis of the invention process is extremely simple.

First of all, the posts 7 are installed in the appropriate locations, using conventional handling means, in particular of the lifting type.

It is emphasized here that the bases 9 will advantageously be positioned first on the ground, then partially filled with sand before

This makes it possible to compensate for any irregularities in the ground level (for example, because the sand will provide the tube with a substantially horizontal surface on which to rest.

Then always at

Using conventional handling means, each supported module 1 is handled so that each of its housings 5 is located above the head 7a of a respective post 7, and the supported module 1 is then lowered until it comes take support on the post 7, then released, the stability of the connection between the supported module 1 and the posts 7 being obtained automatically.

Then, still using conventional handling means, each suspended module 12 is handled and assembled with two adjacent supported modules 1 as described above with reference to FIGS. 12 and 13.

It is emphasized here that one could just as well mount all the supported modules 1 on the posts 7 and then mount all the suspended modules 12, as mount first two adjacent supported modules 1, then a suspended module 12 between said first supported modules 1, then a second supported module 1 adjacent to one of said first supported modules 1, then a suspended module 12 between said first and said second supported module 1, and so on.

The final embedding can be just as well carried out as the modules 1 are assembled as after the assembly of the entire first stage.

One or more ramps will also be installed to access and exit the overhead parking area, the ramp (s) also being advantageously made of several modules assembled together, for example in a conventional manner by bolting, and a ramp module being also assembled to a supported module 1 or suspended 12, again for example by bolting plates provided for this purpose on the ramp module and the supported 1 or suspended 12 module.

It is also possible to install railings 17 on the edge beams 4 and 15, for example here again in a conventional manner by bolting on plates carried by the edge beams 4 and 15, such as for example the plates 4j visible in the Figures 2, 7 and 8 for the supported modules 1 and the 15h plates visible in Figures 10, 12 and 13 for the suspended modules 12. The guardrails 17 will advantageously be installed on site before handling the modules 1 and 12, which allows operators to bolt to the floor, rather than using nacelles to do it at height.

The marking on the ground on the upper surfaces of the supported 1 and suspended modules 12 can be carried out in the factory, on site before installation or on site after installation.

If we finally refer to Figures 15 and 16, we can see that there is shown a two-level overhead parking, formed of supported modules 1, suspended modules 12 and posts 7 as described above .

In order to facilitate the description, the posts which are used to support the modules 1 and 12 forming the apron of the second floor are designated by the reference numeral they are in themselves and which serve similar to the posts to support the apron of the ground floor first floor.

Each post the upper surface of a supported module 1 of the first stage and its longitudinal axis is aligned with that of the corresponding post 7.

The supported modules are supported from above, and the same in the same way as suspended modules 12 of that described second stage are suspended from said supported modules 1 also in the same way as that described above.

According to the preferred embodiment of the present invention, the posts 18 differ from the posts 7 in that their base 19, which comprises a flat base or pad 19a and a cylindrical housing 19b in which the lower end region of the tube is received forming the post 18 and filled with concrete, also comprises an axis 19c which extends downward from the base 19a, opposite side to that from which extends the housing 19b. This axis 19c is dimensioned so that it can be introduced into the tubular part 4g of the supported module 1 of the first stage, and be embedded therein in order to position the base 19.

In other words, the junction between the first stage and the second stage is ensured by the cooperation between the axes 19c of the bases 19 of the posts 18 and the tubular parts 4g of the supported modules 1 of the first stage: the axes 19c allow the times the correct positioning of the posts 18 relative to the posts 7 and also the transmission of the wind forces from the second stage to the deck of the first stage.

In practice, after the elements forming the first stage have been assembled, the bases 19 are positioned as described above, then the posts 18 are positioned in the bases 19, then the supported modules 1 are positioned on the posts 18 as described for the first floor.

It is emphasized here that it will be possible, as for the bases 9 of the posts 7, to partially fill the bases 19 with sand in order to compensate for any level irregularities.

It is also emphasized here that there are no additional fastenings of the base 19a on the supported module 1, only the embedding of the axis 19 in the tubular part 4g is sufficient for the proper maintenance of the assembly. The dimensions of the base 19a will thus be advantageously defined so as to correctly distribute the descending vertical loads, on the concrete slab of the first floor and on the mix on the ground floor.

It is understood that the preferred embodiment which has just been described has been given as edge beams 4 having other structures in indicative and non-limiting and that modifications can be made without being deviates from the scope of the present invention.

Thus, for example, the present invention is not limited to the specific structure described above for the edge beams 4, and it will thus be possible to foresee which the housings 5 and the hooks 4i can be formed otherwise, provided that the lower ends of the housings 5 are open and the hooks 4i have a cylindrical bottom whose axis is parallel to the longitudinal direction 5 of the chassis 2.
