Definitions
- the invention relates to the floating assembly of internal floors of railway or road vehicles, naval vessels or aircraft. It relates more particularly to the use of non-rigid connecting elements - which allow damping vibrations and noise - to suspend an internal floor structure on the support structure of an aircraft, a building naval or rail or road vehicle, for example on the floor of a rail vehicle cauldron.
- EP 0 576 394 discloses elastic connection elements which are particularly efficient in terms of damping of vibrations and noise and which are currently in use, in particular for the floating mounting of internal floors on the floors of the cooking tanks of the vehicles. rail.
- These elastic connection elements comprise a lower element (“Grundprofil”) having a first support wall intended to be fixed on the support structure, an upper element (“Deckprofil”) having a second support wall, substantially parallel to said first support wall and intended to be attached to said inner floor and a resilient mass (“elastische MaBe”) arranged between said lower member and said upper member such that said lower member and said upper member can move one by relative to the other in a direction substantially perpendicular to said first support wall, while remaining distant from one another.
- the time devoted to the preparation of the support structure before the placement of the floor elements is of the order of 5-12 h.
- the connecting elements are obstacles that operators must avoid when moving, so that the intervention devoted to the floating assembly of such floors is particularly long and delicate.
- the floor elements constituting the internal floor are typically panels, slabs or planks, of wood, plastic, metal, or composites, for example having a multilayer structure typically containing two outer metal layers and a core in foamed polymer or having a honeycomb structure. We will then designate them by the general term "panels". They are then assembled and fixed, typically by screwing, on the upper elements of the connecting elements, for example using self-tapping screws.
- the support structure of the cauldron is not perfectly flat, it is necessary, if it is desired to obtain an internal floor of satisfactory flatness, that each connecting element is controlled and adjusted in height before the installation and fixing of the floor element, to account for local height differences resulting from the imperfect flatness of the support structure.
- European patent application EP 1 880 914 describes a vehicle floor structure which comprises at least one rigid bending beam and extending in the longitudinal direction of the vehicle, on which the passenger seat legs are fixed. Between said longitudinal beam and a support floor forming part of the frame, lies an elastic material for decoupling oscillations particularly acoustic which forms with said beam a pre-assembled unit.
- German utility model DE 200 02 265 Ul also describes a floor structure for railway vehicles.
- the floor is supported above the frame provided with transverse beams by means of tubular sections which are arranged longitudinally and which are fixed on said transverse beams, a first compensation of height tolerances being effected by means of shims placed between said transverse beams and said hollow sections, a second height compensation being effected by depositing elastic cords of adhesive between the floor panels and the hollow sections at appropriate intervals.
- the applicant has sought to achieve the floating assembly of an internal floor on a support structure, typically the cauldron of a railway vehicle, resulting in a response time as short as possible, the floor must also present a perfect flatness, independent of flatness defects of the support.
- a first object of the invention is a method of assembling internal floor elements to be fixed on the support structure of railway or road vehicles or ships or aircraft, comprising the following sequence of steps a) at least one elongated structural element, typically a spar, a rail or a slide, which will be designated below by the general term "profiled”, advantageously an extruded profile made of alloy of aluminum, having at least one lower bearing surface, typically horizontal and downward, for attachment to the support structure and an upper support surface, typically horizontal and upwardly oriented, for fastening the panels internal floor;
- each internal floor element is placed so that it rests on said upper support face of said profile and is fixed each internal floor element with second fixing means.
- Said method is characterized in that said height positioning means are grouped together with said first fixing means to obtain height-adjustable connection means.
- the assembly method according to the invention is based on the introduction of at least one profile between the support structure of the vehicle, the ship or the aircraft and the internal floor elements.
- This profile must be set at a predetermined level, corresponding to the altitude of the floor to be mounted.
- As access to this section is relatively easy until the floor panels are mounted, it is possible to introduce between said lower bearing face and said support structure as many height positioning means as necessary to perform the level adjustment.
- the profile and the next step corresponding to the laying of the floor elements is greatly facilitated, since there is more leveling and lateral positioning to be performed on each of said floor elements.
- connection means adjustable in height may be for example sets comprising a lower part having a first support wall, intended to be fixed on the floor of the frame structure and an upper part having a second wall of support substantially parallel to said first support wall and intended to be fixed on said profile, the two parts being movable relative to each other in a direction substantially perpendicular to said support walls.
- Said lower part and said upper part are interconnected by a mechanical connection, called "incomplete", which has at least one degree of freedom, in that it allows said lower part and said upper part to move. one with respect to the other in a direction substantially perpendicular to said first and second support walls.
- said connecting means adjustable in height, that is to say by imposing a relative displacement of the lower part relative to the upper part, it is possible to compensate for height differences related to the lack of flatness chassis structure without there being any need to pre-equip said chassis structure with foreign elements such wedges, bases, supports, etc.
- This incomplete mechanical connection is for example a slide connection which provides 5 degrees of connection and allows only a translational movement in the intended direction.
- This can be a sliding pivot connection with anti-rotation (typically a cylindrical shaft sliding in a bore without rotating about its axis), a helical connection (typically a screw-nut system), or a connection "double plane support” with secant contact planes (typically a system of wedges sliding support).
- the relative movement of the lower part relative to the upper part can be directly imposed manually. It can also be achieved using an intermediate piece whose movement causes the relative movement of the lower part relative to the upper part.
- This intermediate part we will call later this intermediate part "spacer".
- the spacer may be either part of a screw-nut system, one or more translational corners, the body or rod of a cylinder.
- the screw-nut system can be used directly or by means of a pantograph, which makes it possible to orient differently and / or to refine the adjustment of the displacement.
- the spacer can be moved by hand or with the aid of an actuator powered by an auxiliary energy source, such as a compressed spring, an electromechanical, pneumatic or hydraulic cylinder or a deformable enclosure pressurized with air to be used as a pneumatic support.
- auxiliary energy makes it possible to automate and / or remotely control the movement of the lower part relative to the upper part to reach the target gap, for example to allow the profile to be leveled.
- said displacement can be performed after the installation of the profile, even if access to the spacer or the actuator is not very easy.
- step c) the position of said profile is adjusted in the horizontal plane of said profile so that it is correctly positioned relative to a predetermined reference, typically the side walls of said support structure, so that it is also positioned in the horizontal plane relative to the support structure of the vehicle.
- said height-adjustable connection means is also provided with a means for moving in the plane necessary to perform the said adjustment, for example a ball joint.
- said height-adjustable connection means which has been subdivided into two integral and movable parts with respect to each other, is also provided with an immobilization means which immobilizes said lower part relative to to said upper piece, so that said first bearing wall and said second bearing wall can be kept away from each other by a determined constant distance.
- an immobilization means which immobilizes said lower part relative to to said upper piece, so that said first bearing wall and said second bearing wall can be kept away from each other by a determined constant distance.
- the immobilizing means may be a specific means, for example a bead secured to the lower part trapped in a groove secured to the upper part (or vice versa) or any fastening means, such as a screw , to secure the lower part and the upper part.
- a screw-nut connection may be used to provide the retractor function.
- a screw-nut connection is preferably chosen with helical threads of high slope and in low friction contact so that it is preferable to use specific immobilization means, typically a self-locking screw. tap threaded through the screw portion and the nut portion of the screw-nut system, for example at the common area of the fast nets.
- the great advantage of the invention lies in the possibility of pre-equipping the profiles with said connecting means adjustable in height so that at the time of mounting of the profile, there is no loss of time in the preparation of the chassis structure, which, free of prefixed assembly parts, remains easy to access and can be treaded by operators without special precautions.
- the first bearing wall is in the form of a plate which projects beyond the space occupied by the upper part, the periphery of said plate being provided with orifices or being intended to be pierced for the passage of fixing screws.
- the lower face of the first support wall is provided with an adhesive layer or is intended to be coated with an adhesive material, preferably just before the establishment of the profile on the structure. -frame.
- the periphery of the lower face of the first support wall is surrounded by a continuous bead, so that when the connecting element is brought into contact with the floor of the structure, frame, it is formed between said floor and said first support wall a cavity adapted to receive the adhesive material injected from the top of the profile.
- said second support wall is advantageously provided with an orifice whose diameter is defined to allow access to said spacer and / or said actuator (to adjust the gap between the part lower and the upper piece) and / or said immobilizing means (to fix said gap), or even to the first support wall (for fixing the connecting element on the floor of the frame structure).
- connecting means adjustable in height and their implementation on the profile depends on the width of said profile and its rigidity in the longitudinal direction.
- the spacing between connecting means adjustable in height is defined so that the height position of the profile can be easily adjusted at any point of attachment and that a straight profile is obtained in a horizontal plane of predetermined altitude.
- said height-adjustable connection means are associated with vibration damping and noise damping elements, so that they form height-adjustable elastic connection elements.

- an upper element having a second support wall substantially parallel to said first support wall and intended to be fixed on said profile
- Said lower element (respectively said upper element) comprises at least two moving parts relative to each other in a direction substantially perpendicular to said support walls.
- Said first moving part is adjacent to said elastic mass and said second moving part is or comprises said first bearing wall (respectively the second support wall).
- the profile may be pre-equipped with said elastic connecting elements adjustable in height so that at the time of mounting of the profile, there is no loss of time in the preparation of the floor of the chassis structure, which, free of prefixed parts, remains easy to access and can be trodden by operators without special precautions.
- the number, the distribution and the adjustment stroke of said height-adjustable elastic connecting elements arranged on said profile depend on the morphology of the support structure and the rigidity of the profile.
- the gain in preparation time and laying of floorboards is considerable because these, automatically at the right height, are placed in the same plane so that it is no longer necessary to perform the global upgrade mentioned above, which consists of pouring over all of said panels a self-leveling semi-liquid mass, which adds weight to the whole vehicle and requires a long drying time.
- the panels no longer requiring finishing operations after installation, can perform other functions. They can for example be immediately covered with a floor covering, be provided with anchoring means, integrated heating system, etc.
- the preparation and laying time of an internal floor typically from 24 hours to 8 hours, and the time can be reduced considerably. cycle, that is to say the time of passage from one step to another of the assembly process while avoiding at least the waiting time associated with the global upgrade, where it It takes several hours for the self-leveling mass to dry before being able to work on the floor again.
- the floor elements When a single rail is laid, the floor elements, preferably pre-equipped with elastic connecting elements arranged at least at their ends, are fixed on said profile following a mediator said element, which is in general a rectangular panel.
- At least two rails or elongate structural members are placed on the support structure, sufficiently distant from each other so that they can serve as supports for said floor elements. They are placed for example on the longitudinal edges of said support structure, or possibly in the transverse direction, or even diagonally. They must be sufficiently distant from each other, preferably parallel to each other, so that they serve as a support for the floor panels, preferably in the vicinity of each of their ends.
- the support structure is a rail vehicle boiler, in which the profiles used are placed longitudinally, their length substantially corresponding to the target length of the floor, that is to say, in general , approximately the length of the cauldron. They are preferably placed on the lateral edges of the cauldron, the distance between them corresponding to the target width of the floor, typically the width of the cauldron, the inner floor panels to be deposited having a length that corresponds substantially to said width of the cauldron.
- profiles may optionally be placed between the profiles placed on the side edges, preferably parallel to them.
- Said profiles in particular if they are extruded aluminum profiles that may have sections of complex shape, may perform functions other than "floating floor support”: they may for example have a wall facing inwards of the floor. cockpit, whose "bowl edge” shape prevents accumulation and stagnation of water, so as to facilitate the cleaning of the vehicle and limit the risk of corrosion; they can also be used for seat attachment or as cable ducts, as hot air ducts, or as runners along which they can slide. mobile frames, assembly tools for preparing and / or assisting the fastening of vertical panels, etc. ...
- the floor elements are fixed on the profiles with the aid of said second fixing means.
- said second fixing means are advantageously associated with non-rigid connecting elements.
- these are semi-rigid connecting elements, for example rivets, screws or bolts associated with washers or wedges of resilient material, or elastic connecting elements, for example those described in EP 0 576 394, or possibly, a set of elastic connecting elements adjustable in height similar to those described in WO2011 / 160755.

- the foam blocks the height must be such that each block must be compressed after mounting the floor element between said floor element and said support structure. In this way, most of the vibrations are damped, at least in the vertical direction.
- said elastic connection elements are regularly distributed, at least close to a lateral edge of a floor element, preferably near the two lateral edges, preferably on the entire surface of the element. floor.
- elastic connection elements adjustable in height such as those described in WO2011 / 160755 is advantageous because the latter, especially if they are fixed on the profiles before laying them on the support structure , allow to simplify and accelerate the adjustment by avoiding the use of shims to place the profiles at the right level.
- These elements are arranged in limited numbers on the rails and are intended to support dynamic and static loads greater than the elastic connection elements which, more numerous, directly support the floor elements.
- the resilient mass must be of an elastic material able to withstand for a long time the said significant static and dynamic forces.
- the section of the profile also has a curved wall facing the interior of the passenger compartment of the railway vehicle, the shape of which "bowl edge" prevents the accumulation and stagnation of liquid - typically the water brought by passengers when it is raining or snowing or detergents and washing water used for cleaning the vehicle - which limits the risk of corrosion, the cauldron in particular.
- the present invention allows to individualize the anti-vibration function, to adapt to each floor element.
- the elastic connecting elements are more suitable in the case where the profiles used must perform other functions, the vibration damping required for a floor is not necessarily the same as that required for a seat, or the one required for a panel decorative. Designed to support long-term static and dynamic forces of less amplitude, the elastic connecting elements can be smaller, less bulky than those used for fastening the profiles.
- the panels are advantageously provided on their underside - the face to be placed vis-à-vis the support structure of the vehicle - elastic connecting elements.
- said elastic connection elements are regularly distributed over the surface of said floor elements. It could be:
- each block must be such that each block is, after mounting the floor element, compressed between said floor element and said support structure.
- Said foam blocks have the advantage of not requiring any adjustment after installation and fixing of the floor element;
- non-height-adjustable elastic connection elements such as those described in EP 0 576 394, judiciously disposed on the floor element, for example regularly distributed near the edge of the floor element intended to rub an element of panel already installed, so that the establishment on the support structure wedges for their proper leveling can be done easily, panel after panel, as and when the laying of said floor.
- these panels especially if the set of second fastening means is not a set of connecting elements adjustable in height, may also be already provided with a floor covering (carpet , linoleum, ...), anchor points (inserts), or even an integrated heating system.
- a floor covering carpet , linoleum, ...), anchor points (inserts), or even an integrated heating system.
