Description

TECHNICAL FIELD TO WHICH THE INVENTION RELATES

The present invention relates generally to the field of road equipment and works. It relates more particularly to a hybrid metal-concrete traffic lane separator module intended to produce traffic lane separation barriers, and in particular temporary ones. A method of making a traffic lane separation barrier by connecting modules is also presented.

TECHNOLOGICAL BACKGROUND

Modular dividers that are assembled to form a delimitation of traffic lanes must have sufficient capacity to restrain vehicles striking them. These capacities are generally recommended in standards.

Modular dividers are known from documents EP1380696 and EP3029202 . If they have certain advantages in terms of ease of handling compared to modules made of concrete blocks, they however have a relatively low inertia because of their relatively low weight. In addition, for the first document, the operations of securing the modules together can prove to be tedious due to the fact that it is necessary to aim correctly so that the pins come to be placed opposite the corresponding insertion holes at the ends of the modules. This is all the more difficult as the machine handling the module must take it in the middle to best balance the load represented by the module, this constraint being all the more critical as the weight of the module is important, and the The operator of the machine is therefore generally at a distance from the ends of the module and, what is more, these ends are partly hidden by the body of the module. Besides the weight, this masking and this distance also increase with the length of the module.

We also know the document EP0997582 A1 which discloses a metal-concrete module in which the screws of the connecting means between adjacent ends of modules are constrained in terms of their head spacing from the end of the module carrying them due to the presence of pegs (elongated wedges) 44. In addition, due to the funnel shape of the part 141 and inclined 143, an automatic longitudinal and transverse alignment of the elements is obtained (cf. paragraph 69).

The present invention is distinguished from it by the possibility of offset between the modules to follow a bend or a slope, thanks to the freedom of rotation of the pin screws ensuring the connection between the modules.

It is therefore desirable to have modules having a greater inertia, in particular by increasing the weight, and greater ease of joining the modules together, even for modules of great unit length. It is also useful to be able to adjust the integral modules to the shape of the roadway on which they are installed, whether for a break in slope or for a bend and, this, without causing a detrimental reduction in the holding capacity. from the whole.

OBJECT OF THE INVENTION

In order in particular to remedy the aforementioned drawbacks of the state of the art, the present invention proposes a hybrid metal-concrete module for separating traffic lanes, the modules being intended to be placed on a traffic road in order to form a barrier delimiting the traffic lanes. traffic lanes, the module being a straight element with a main axis elongated longitudinally between two connecting ends intended to be connected to the connecting ends of two other adjacent modules to form an alignment of modules joined together, each module comprising downwards a base part, upwards a ridge part, interconnected by uprights extended between the base part and the ridge part, the module being substantially symmetrical with respect to a longitudinal vertical median plane, the base part being wider than the ridge portion, each connecting end having a perpendicular vertical metal end face e to the main axis of the module, the end face being intended to be placed opposite an end face of another adjacent module in the alignment of modules.

The connecting ends comprise on their end faces complementary means for securing the modules to each other, the complementary securing means comprising pins and elongated slots, a given pin fixed on a connecting end being intended to be passed and positioned. in a slot in correspondence with the other connecting end in order to prevent the modules from separating from each other at least along the main axis, each mushroom-shaped pin comprising a barrel terminated at its free end by a head that is wider than the shank, each pin projecting horizontally and parallel to the main axis of the module outwards from the end face to which it is attached, and each slot is lengthened vertically and passes through the thickness of the end face , at least a part of each slot having a width allowing the passage of the shank of the pin but not of the head of the pin in order to be able to retain in said part of the slot a pawn passed through the corresponding slot.

The spacing of the pin head from the end face to which it is fixed is adjustable in order to be able to adjust the clamping or the axial spacing and maximum angular tolerated between the link ends of two connected modules.

The invention also relates to a method of producing a traffic lane separation barrier by connecting modules, the modules comprising a metal frame and concrete, the modules being placed on a traffic roadway of a site, in which method modules according to the invention are used, either the metal frames are transported to the site and, once on site, concrete is poured in the base part of the modules, or the modules with their concrete in the base part, and to connect a new module to a module already installed on the ground, we bring the new module raised above the ground substantially in the axis of the module already installed on the ground so that their opposite end faces include securing means which are complementary to each other, and one engages between them the means of fastening of the type of pins and slots, the descent to the ground of the new module joining the two modules, and the spacings are adjusted. ents of the pin heads relative to the end face to which said pins are fixed in order to be able to adjust the clamping or the maximum axial and angular spacing tolerated between the connecting ends of the two modules.

In a particular implementation of the method where two interconnected modules are angularly offset, and for the two screw-type pins located at the level of the base part, the spacing of the head of the pin is adjusted differently for each of said two pins by relative to the end face to which it is fixed so that the connecting ends of the two connected modules are further apart on a lateral side relative to the other lateral side.

In particular implementations of the method, the connecting ends of the two connected modules can be force-tightened one against the other or, on the contrary, leave the possibility of a predefined play.

It is understood that this principle of angular offset in the configuration of joining the modules can relate to an angulation in a horizontal plane if the roadway has for example a bend but also an angulation in a vertical plane if the road has a break in slope and, more generally , the invention allows angular offsets combining the vertical and the horizontal in order to be able to adapt to all forms of pavement.

Device

The hybrid metal-concrete separator module of the invention comprises a metal framework made up of metal parts welded together and the lower part of which, called the base part, forms a permanent formwork in which concrete has been poured, or can be poured. . Concrete significantly increases the weight of the module. Concrete also provides additional relative resistance against deformation of the metal in the event of an impact. However, in the preferred embodiment, concrete is not chosen and / or implemented to have optimum impact resistance and, in particular, it is not reinforced or prestressed or loaded with fibers or the like. A standard concrete is preferably used, the main characteristic of which is that it is inexpensive.

The proposed module makes it possible to retain a light vehicle or a heavy vehicle with a relatively reduced deformation of the barrier made up of separator modules connected together, and this typically according to the T3W2, H1W4 standards. It also makes it possible to prevent the wheels and in particular the bolts for fixing the wheels of heavy vehicles from resting on the metal parts of the module, risking lifting the vehicle.

On the figure 1 , the hybrid module 1 has three main parts, upwards a ridge part 2, downwards a base part 3 and between the two of the uprights 4, 5 and 6 connecting the two. The area between the ridge part and the base part is essentially empty with the exception of the uprights. Among the uprights, those at the two longitudinal ends of the module form the connecting ends 5, 6 of the module 1. The module is straight and it is elongated longitudinally, that is to say in the direction of the length forming its main axis. . The module is substantially symmetrical with respect to a longitudinal vertical median plane and presents, when viewed transversely, a template of truncated pyramidal shape, with a broad base towards the bottom.

The area of module 1 between the ridge part and the base part is essentially empty except for the uprights. In certain methods of implementation, provision is made to fill this zone by any useful means and for example plates extended between the ridge and base parts.

Each link end 5, 6 of the module 1 has a vertical metal end face 50, 60 perpendicular to the main axis of the module. Each end face is intended to be placed opposite a complementary end face of another adjacent module in an alignment of modules. The connecting ends 5, 6 comprise on their end faces 50, 60 complementary means for securing the modules together. These additional securing means are in this example screw type pins 9 and slots 19. The screws 9 have maneuverable screw heads and threaded shanks and can be screwed and unscrewed on the connecting end 5, 6 the bearing, which makes it possible to adjust the spacing of the head of the pin, the head of the screw 9 in this case, relative to the end face to which it is fixed. The shanks of the screws 9 can be passed through the slots 19 in correspondence with the screws 9. This results in an interlocking fastening, of the button type.

The ridge portion 2 consists of two continuous horizontal parallel side slides 20 separated and held together by transverse horizontal spacers 21. The two lateral slides 20 are also fixed to the upper ends of the uprights 4, 5 and 6. The slides 20 are extended longitudinally between the two connecting ends 5, 6 of the module 1. Each slide forms a side wall of the ridge part which is vertical. The slides 20, spacers 21, uprights 4, 5, 6 are metallic and welded together.

The base part 3 has two longitudinal lateral sides each consisting of two parallel metal side rails, horizontal and superimposed vertically. The rails 30 are metallic and are welded to the lower ends of the uprights 4, 5, 6. The two rails 30 on each lateral side can be welded together. The two rails 30 on each lateral side form a side wall of the base part which is vertical. The side rails 30 are extended longitudinally between the two connecting ends 5, 6 of the module 1. A bottom element 31 in particular visible on the figures 2 , 5A and 5C , closes down the base part 3 and is extended transversely between the side rails 30 of the two lateral sides of the base part 3. This bottom element 31 in one piece or resulting from an assembly of several plates is extended longitudinally between the two connecting ends 5, 6 of the module 1. The bottom element 31 in the case where it is metallic, is welded to the rails 30. The bottom element can be removable and is removed once the concrete solidified. The bottom element can be made of wood.

Preferably, the slides 20 and the rails 30 are standard U-shaped metal sections and those of the U-shaped legs 70 with returns, in particular of the type serving as a stake / support for stringers at the edge of the whole. It can be the same for the spacers 21 of the ridge part 2. In the example shown, the spacers 21 of the ridge part 2 and the upper parts of the connecting ends 5, 6 of the module 1 are cut sheets. , shaped if necessary and assembled by welding and the same for the connecting ends 5, 6. Still in this example, the slides 20 and the rails 30 are standard U100 profiles. The metal parts have suitable thicknesses with for example 10 mm for the connecting ends, 5 mm for the spacers, between 4 and 5 mm for the rails and slides

The entire framework of the module, made up of welded metal parts, is hot-dip galvanized.

The module 1 shown has three uprights 4 intermediate between the two link ends 5 and 6. The module 1 shown has four spacers 21 in the ridge portion, each substantially equidistant from the two adjacent uprights 4, 5 or 6.

The rails 30, the bottom element 31 and the connecting ends 5, 6 form a lost formwork in which a concrete 8 is poured as can best be seen in fig 2 or figures 5A and 5C . The module 1 therefore comprises a mass of concrete 8 longitudinal median. The concrete is preferably continuous between the two ends, the uprights being drilled at the height of the base part so that the concrete communicates on both sides of the uprights. In one variant, the concrete is compartmentalized.

Once the concrete is in place and solidified / set, the module has a total mass of approximately 1155 kg for a module of 6 m useful length (approximately 6.15 m overall), 0.3 m wide at the level of the base part and 0.71 m high. The width of the module at the ridge part is 0.26 m. The assembled metal parts forming the framework of the module have, before concrete pouring, an approximate weight of 390 Kg and the concrete alone, after drying, an approximate weight of 765 Kg. The volume of concrete is approximately 0.310 m ³ per module.

It can be noted that the width of the ridge part, approx. 260 mm is suitable for handling the block with existing standard grippers for unloading and loading on a semi-trailer. In the example shown, the modules have a unit length of 6 m but in variants, provision is made for modules with a length of 2 m, 4 m and 12 m for specific uses.

In implementation variants, it is possible to replace the concrete in part or in whole with other heavy materials, for example gravel, or even liquids such as water. In a particular case, concrete is provided towards the bottom of the base part 3 and cultivated soil above, in the permanent formwork and flowers are cultivated there, for example. Note that one can provide for the installation of flower boxes or other plants between the two slides 20 of the ridge part 2.

Optionally, spacers (not visible and not provided in the preferred embodiment) can be fixed transversely between the rails 30 of the two lateral sides of the base part 3 and taken in the concrete.

More particularly on figure 5C and 5D , we can see a reservation in the concrete surface and which comprises a housing 11 which is therefore caught in the concrete. This housing 11 can internally include any document and / or device, mechanical or electronic, useful and, for example an RFID identifier or equivalent, a mechanical or electronic shock detector. In the latter case, provision can be made for the shock detector to be able to generate electricity during the shock and that this electricity can supply the device temporarily to allow certain operations, including recording the shock in a memory, in particular FLASH®. In other embodiments, the box 11 comprises an electric battery or, optionally, a rechargeable battery if an external electric power source such as for example a photovoltaic panel, is available. It should be noted that the term box is generic and that this can equally well correspond to an encapsulation by resin or the like of the device, as to a box inside which the device is placed.

The module 1 rests on the roadway by means of feet 7 comprising U-shaped sections with returns 10 fixed longitudinally to the underside of the base part 3 and a plate on which a layer of an elastomer 71 is fixed. An elastomeric interface is therefore present between the module 1 and the roadway, which ensures satisfactory grip capacity. In variants, provision can be made for the plate on which a layer of an elastomer 71 is fixed to further include points downwards and protruding from the elastomer and sinking into the roadway or the ground to further increase the adhesion. Finally, in some cases, provision is made for piles to be inserted through the module and driven / forced or screwed into the roadway to positively anchor the module to the ground.

We will now detail the connection ends 5, 6 of module 1 with the figures 3, 4 and 8 . The connecting ends 5, 6 have a general profile substantially H in horizontal section with two vertical transverse walls parallel to each other and medially connected to each other by a vertical median axial wall, one of the two transverse walls corresponding to the end face of the module 1. Thus, on the side of the connecting end referenced 5 in the figures, one of the two transverse walls corresponds to the end face 50, the other to the internal wall 52, the two being connected by the axial wall. median 51. On the side of the connecting end referenced 6 in the figures, one of the two transverse walls corresponds to the end face 60, the other to the internal wall 62, the two being connected by the median axial wall 61. .

The complementary screw-type securing means 9 and the slots 19 are distributed between the two connecting ends 5, 6 to be complementary between the modules and to provide retaining forces against the separation of the modules with a certain symmetry. On the side of the connecting end referenced 5 in the figures, two slots 19 are arranged on the end face 50 downwards, at the level of the base part 3, and a screw upwards, at the level of the ridge part 2. The screw protrudes from the end face 50 and can be screwed in, which brings the head of the screw closer to the end face 50, or unscrewed, which keeps it away. The screw is placed on the vertical median plane of the module.

On the side of the connecting end referenced 6 in the figures, a slot 19 is arranged on the end face 60 upwards, at the level of the ridge part 2 and two screws downwards, at the level of the part. 3. The screws protrude from the end face 60 and can be screwed in, which brings the screw heads closer to the end face 60, or unscrewed, which pushes them apart. The two screws are placed on the same level and symmetrically with respect to the vertical median plane of the module.

This alternation between the slots and the screws between the two ends of the module prevents unhooking between assembled modules in the event of a collision of a vehicle against the barrier.

In the exemplary embodiment shown, the slots 19 have a uniform width over their height and which allows the passage of the threaded shank of the screws 9 but not of their heads. The slots open onto the top or bottom edge, as the case may be, of the corresponding end face. As a result, the modules are joined together by essentially vertical translation between two opposite ends of two adjacent modules so that the shank of the screw enters the slot and the head of the screw passes from the other side of the end face as can be seen on the figure 8 .

When installing the modules to secure them together, care should be taken to unscrew the screws somewhat in order to have sufficient play to facilitate the insertion of the screw drums into the slots. Once the insertion has been made, the screws can be tightened again to press the two end faces against each other for a straight barrier without angulation between modules. If one wishes an angulation between two modules, one will leave a certain play in the screws in order not to press the end faces and to leave an angulation between them. Thanks to this angulation between the end faces of the modules, it is possible to produce a barrier with an admissible radius of curvature of 72 m for modules 6 m long. This radius of curvature is adjustable according to the tightening of the screws. It can be noted that in this case of angulation, there is a possibility of small angular displacement of the modules between them in the event of an impact. It is therefore possible to provide for the insertion of a wedge between the end faces which form an angle between them in order to block / eliminate this play once the barrier is installed.

The screws are of the M42 type and a washer is welded to the head of the screw. A nut 18 is welded to the end face 50, inner side of the connecting end 5, by means of a support washer as visible figure 8 for the ridge part 2. The same principle is used for the two screws of the base part 3, the nuts with welded support washers being this time welded to the end face 50 on the inside of the connecting end 6. In order to be able to access the heads of the screws 9 for screwing or unscrewing them, a free space is left on the side inside the uprights forming the connecting ends 5 and 6. For the ridge part 2, as visible figure 8 , this space is further completed by a cutout of the internal wall 62 of the connecting end 6. For the base part and as better visible figure 4 , the free space is behind the plate 53 and, preferably, this plate 53 is removable to improve access to the screw head. Preferably, the removable plate 53 can be clipped and unclipped. For screwing and unscrewing, a ratchet key is preferably used which has the advantage of not requiring a large angular movement and can remain engaged on the head of the screw during screwing and unscrewing.

The figure 9 allows you to visualize more precisely the way in which a module can be constructed. It should be noted immediately that on the exploded view of the figure 9 , the concrete 8 which is represented therein is schematically / symbolically because it is well understood that it does not appear in reality as a homogeneous bar given that it crosses and is taken in the uprights 4. It is in fact recalled that this concrete is poured into the lower part of the metal frame. It can be noted that the two metal feet 7 are fixed on two of the uprights 4. During the manufacture of the metal frame, on the one hand, the intermediate uprights 4 and ends 5 and 6 are made, then welded therein, by at the top, two side rails 20 and the spacers 21 between the rails 20, and at the bottom, two side rails 30 on each lateral side. It can be noted that in this embodiment, the bottom element has not been shown because it is used temporarily during the pouring and setting of the concrete 8 to close down the lost formwork of the lower part and it is then reused for pouring concrete into another frame and so on. In another embodiment, the bottom element is left in place definitively in the module, this bottom element possibly being metallic or wooden. Finally, we can note on the upper face of the concrete 8 a reservation corresponding to the housing 11.

For the transport of the hybrid metal-concrete separator modules, a semi-trailer with a platform of about 13.6 m and a useful loading height on the platform of 2.65 m can be used. Under these conditions we can load 20 blocks with concrete or 120 linear m of barrier as shown. figure 6 in rear view of the load with the stack of modules. The bottom row of five modules is aligned along the length of the top and the top layers are installed at an angle for better stability, four modules for the middle row and one for the top of the stack. The The limit on the number of modules transported is here imposed by the unit weight of each module with concrete with regard to the capacities of the semi-trailer, in this example a 44 T truck.

Provision can be made to transport only the framework of the module and to pour the concrete only once it has arrived at its destination and the frameworks unloaded. The concrete is poured with a router on arrival at the depot or even on the site once the barrier is installed. In this case and for the same type of semi-trailer, forty-two frames (modules without concrete) can be transported, ie 252 linear m of barrier. This possibility is shown in the figure 7 . In addition, the frames can be loaded and unloaded with a simple “Manitou®” due to the relatively low weight of each frame unlike the module with concrete.

It can therefore be seen that the modules and frames are stacking / stackable at several heights thanks to the base part forming a flat base and to the robustness and stability of the product. This stability is obtained although the module has a relatively narrow base, which is an advantage in work areas where the available space can be relatively small, such as in an urban environment.

The module and the framework composing it can be used in many other ways. The metal parts constituting it, in particular the slides and rails may have dimensions and / or shapes different from those of the example shown. Various accessories can be combined such as optical deflectors, lighting, masking or anti-glare screens. It is also possible to provide a jumper plate for cladding / integral blackout screen, delineators with reflectors, connection covers on DBA, GBA and DBAT. More generally, openings are originally provided on the metal parts of the framework of the module and which can be used to fix accessories thereto. At the end of the barrier produced, a connection kit can be installed on a Walt temporary shock attenuator, a special anti-tilt and line interruption casing, a connection kit on the site gate / service access, one end lowered. If the modules are particularly useful for the realization of temporary barriers, simply placed on the roadway, it is possible to provide for long-term anchoring and / or installation, or even definitive installation. It is thus possible to provide a module allowing the installation of anchoring piles in particular for the treatment of the end modules of the barrier in final installation.
