Description

La présente invention concerne un concerne un ensemble support pour un élément de toiture, un abri comprenant un tel ensemble support et un procédé de montage d'un tel abri.The present invention relates to a support assembly for a roof element, a shelter comprising such a support assembly and a method of mounting such a shelter.

On a représenté sur la figure 1 un abri selon l'état de la technique. Il comprend un mât central 2 et un élément de toiture constitué d'un cadre quadrangulaire 3, formant armature, et d'une toile tendue 4. La toile tendue 4 comporte un orifice central traversé par le mât 2. La périphérie de cet orifice est fixée à une cerce 5 montée sur le mât 2. La périphérie externe de la toile 4 est fixée au cadre 3. Des câbles 6 de maintien du cadre et de tension de la toile relient des points de fixation 7 du cadre à une bride 8 fixée au sommet du mât central.We have shown on the figure 1 a shelter according to the state of the art. It comprises a central mast 2 and a roof element consisting of a quadrangular frame 3, forming a frame, and a stretched fabric 4. The stretched fabric 4 comprises a central orifice through which the mast 2 passes. The periphery of this orifice is attached to a pole 5 mounted on the mast 2. The outer periphery of the fabric 4 is fixed to the frame 3. Cables 6 for maintaining the frame and tension of the fabric connect attachment points 7 of the frame to a fixed flange 8 at the top of the central mast.

Le montage de cet abri se déroule de la manière suivante. La toile 4 est posée sur le sol de sorte que le socle devant recevoir le mât central 2 apparaisse dans l'orifice de la toile 4. Le cadre 3 est ensuite amené ou assemblé sur le sol autour du socle puis le mât 2, comprenant la cerce 5, est érigé à l'aide d'une grue. La périphérie interne de la toile 4 est alors fixée à la cerce 5 et sa périphérie externe est fixée au cadre 3. Dans cette position la toile 4 n'est pas tendue.The assembly of this shelter takes place in the following way. The fabric 4 is placed on the ground so that the base to receive the central mast 2 appears in the hole of the fabric 4. The frame 3 is then brought or assembled on the ground around the base and the mast 2, including the cerce 5, is erected using a crane. The inner periphery of the fabric 4 is then fixed to the hoop 5 and its outer periphery is fixed to the frame 3. In this position the fabric 4 is not stretched.

La mise en place du cadre est réalisée elle aussi avec la toile détendue. Le cadre 3 est soulevé à l'aide de la grue. Les câbles 6 sont alors mis en place et leur longueur ajustée. La mise en tension de la toile 4 est obtenue en augmentant la distance verticale entre le cadre 3 et la cerce 5. Ceci peut être réalisé par l'utilisation d'un mât central de type télescopique que l'on allonge (dans la partie entre la cerce et le sommet du mât) ou par l'utilisation d'un mât non télescopique, en descendant la cerce le long du mât puis en la verrouillant dans la position finale désirée.The setting up of the frame is also carried out with the relaxed canvas. Frame 3 is lifted using the crane. The cables 6 are then put in place and their length adjusted. The tensioning of the fabric 4 is obtained by increasing the vertical distance between the frame 3 and the hoop 5. This can be achieved by using a telescopic central mast that is extended (in the part between the mast and the top of the mast) or by the use of a non-telescopic mast, in descending the circle along the mast and locking it in the desired end position.

Le procédé de montage de l'abri selon l'état de la technique présente des limitations. En effet, du fait de la nécessité d'utiliser une grue, notamment pour soulever le cadre, il est parfois difficile de monter l'abri lorsque la hauteur libre au-dessus de l'abri est limitée, par exemple en raison de la présence d'arbres, ou lorsque l'emplacement où doit être monté l'abri est exigu et ne permet pas à la grue d'évoluer facilement.The mounting method of the shelter according to the state of the art has limitations. Indeed, due to the need to use a crane, especially to lift the frame, it is sometimes difficult to mount the shelter when the free height above the shelter is limited, for example due to the presence trees, or when the location where the shelter is to be mounted is small and does not allow the crane to move easily.

Dans le domaine des ensembles supports pour éléments de toiture ne nécessitant pas de grues pour leur montage, on connaît déjà une tente, objet du brevet US 3 875 952 , qui comporte un ensemble support comprenant un mât central, une cerce fixée au mât central pour recevoir une partie de la toile, une bride fixée sur la partie supérieure dudit mât central comportant un ensemble de poulies radiales et une bague montée coulissante sur le mât. Toutefois, l'ensemble poulies câbles sert à relever les cotés de la toile pour rendre accessible l'intérieur de la tente et non au montage de ladite tente.In the field of support assemblies for roof elements that do not require cranes for their assembly, a tent is already known which is the subject of the patent. US 3 875 952 , which comprises a support assembly comprising a central mast, a cerce attached to the central mast to receive a portion of the fabric, a flange fixed on the upper portion of said central mast having a set of radial pulleys and a ring slidably mounted on the mast. However, the cable pulleys assembly is used to raise the sides of the canvas to make accessible the interior of the tent and not the mounting of said tent.

On connaît aussi un chapiteau de grande superficie, objet du brevet US 3 743 734 , qui comporte une pluralité de mâts destinés à supporter une toile et comportant un ensemble de trois poulies radiales. Sur chaque mât, sont montés coulissant du haut en bas un premier, un deuxième et un troisième anneaux qui sont chacun retenus par le biais d'une corde, d'une chaîne et desdites poulies, pour les mettre en place et éviter qu'ils ne chutent au sol. Toutefois, les dits mâts ne disposent pas de bagues de tension et la mise sous tension de la toile en partie solidaire du troisième anneau est obtenue par l'action de la gravité et de plusieurs bras articulés sur le premier anneau et maintenus en position par le deuxième anneau.There is also a capital of large area, object of the patent US 3,743,734 which comprises a plurality of masts for supporting a fabric and having a set of three radial pulleys. On each mast, are mounted sliding from top to bottom first, second and third rings which are each retained by means of a rope, chain and pulleys, to put in place and prevent them do not fall to the ground. However, the said masts do not have tension rings and the tensioning of the fabric partially integral with the third ring is obtained by the action of gravity and several arms articulated on the first ring and held in position by the second ring.

Un but de la présente invention est de proposer une solution alternative d'abri dont la structure est telle que son montage est avantageusement facile et peut être effectué sans grue, et donc an particulier dans des environnements exigus ou encombrés et/ou de hauteur libre faible.An object of the present invention is to provide an alternative shelter solution whose structure is such that its mounting is advantageously easy and can be carried out without crane, and therefore particularly in confined or congested environments and / or low free height .

Plus précisément, la présente invention a pour objet un ensemble support d'un élément de toiture, cet élément de toiture comportant un cadre et une toile destinée à être tendue entre le cadre et l'ensemble support, cet ensemble support comprenant un mât central; une cerce fixée au mât central, pour recevoir une partie centrale de la toile; une bride fixée dans une partie supérieure du mât central, cette bride comportant un ensemble de poulies radiales; et une bague de tension montée coulissante et verrouillable sur le mât central.More specifically, the subject of the present invention is a support assembly for a roof element, this roof element comprising a frame and a fabric intended to be stretched between the frame and the support assembly, this support assembly comprising a central mast; a cerce attached to the central mast, to receive a central part of the canvas; a flange fixed in an upper part of the central mast, this flange comprising a set of radial pulleys; and a tension ring mounted sliding and lockable on the central mast.

Cette structure particulière de l'ensemble support permet de monter l'abri sans devoir recourir à une grue, comme on le décrira plus en détail dans la suite de la description.This particular structure of the support assembly allows to mount the shelter without having to resort to a crane, as will be described in more detail in the following description.

De manière avantageuse, l'ensemble support comporte également une pluralité de câbles, chaque câble ayant une première extrémité fixée à la bague de tension et étant passée sur une des poulies.Advantageously, the support assembly also comprises a plurality of cables, each cable having a first end attached to the tension ring and passed over one of the pulleys.

La présente invention a également pour objet un abri du type à mât central et élément de toiture monté sur le mât central, ledit abri comprenant un ensemble support conforme à l'invention, un cadre autour du mât central de l'ensemble support, et une toile tendue dont une partie centrale est fixée à la cerce de l'ensemble support et une partie périphérique est fixée au cadre, une deuxième extrémité de chaque câble étant fixée au cadre et la bague de tension étant verrouillée sur le mât central dans une position telle que les câbles sont tendus.The present invention also relates to a central pole type shelter and roof element mounted on the central mast, said shelter comprising a support assembly according to the invention, a frame around the central mast of the support assembly, and a stretched canvas, a central portion of which is attached to the bracket of the support assembly and a peripheral portion is attached to the frame, a second end of each cable being fixed to the frame and the tension ring is locked on the central mast in a position such that the cables are tensioned.

Selon un mode de réalisation préféré, le cadre est quadrangulaire. Les câbles sont de préférence fixés sur le cadre en des points de fixation régulièrement répartis.According to a preferred embodiment, the frame is quadrangular. The cables are preferably fixed to the frame at regularly distributed fixing points.

L'invention a encore pour objet un procédé de montage d'un abri comprenant les étapes suivantes :

  • ériger un ensemble support selon l'invention,
  • disposer ou assembler un cadre autour de l'ensemble support,
  • fixer la deuxième extrémité de chaque câble à des points de fixation respectifs du cadre,
  • fixer une toile ayant une périphérie externe et un orifice central définissant une périphérie interne sur le cadre par sa périphérie externe et sur la cerce de l'ensemble support par sa périphérie interne,
  • tirer la bague de tension vers le bas pour élever le cadre, et
  • verrouiller la bague de tension sur le mât central.
The invention further relates to a method of mounting a shelter comprising the following steps:
  • erect a support assembly according to the invention,
  • arrange or assemble a frame around the support assembly,
  • attaching the second end of each cable to respective attachment points of the frame,
  • attaching a fabric having an outer periphery and a central orifice defining an inner periphery on the frame by its outer periphery and on the cerce of the support assembly by its inner periphery,
  • pull the tension ring down to raise the frame, and
  • lock the tension ring on the center mast.

On comprend que ces étapes peuvent ne pas être exécutées dans l'ordre indiqué. Par exemple, la toile peut être disposée sur le sol autour du socle avant d'ériger l'ensemble support et l'étape de fixation de la toile peut précéder l'étape de fixation des câbles sur le cadre.It is understood that these steps may not be executed in the indicated order. For example, the fabric can be placed on the floor around the base before erecting the support assembly and the step of fixing the fabric can precede the step of fixing the cables to the frame.

Le procédé peut comprendre une étape de déplacement de la cerce vers le haut, avant l'étape de tirage de la bague de tension vers le bas et/ou une étape de tirage de la cerce vers le bas après l'étape de tirage de la bague de tension vers le bas.The method may include a step of moving the cerce upward, before the step of pulling the tension ring down and / or a step of pulling the cerce down after the pull step of the tension ring down.

On décrira ci-après à titre d'exemple non limitatif, une forme d'exécution de la présente invention, en référence au dessin annexé sur lequel :

  • la figure 1, déjà décrite, représente un abri selon l'état de la technique,
  • les figures 2 à 8 représentent des vues de côté ou en perspective illustrant les différentes étapes du montage de l'abri selon l'invention, et
  • la figure 9 montre en détail le sommet du mât central au moment où le cadre est en train d'être élevé.
One embodiment of the present invention will be described hereinafter by way of nonlimiting example, with reference to the appended drawing in which:
  • the figure 1 , already described, represents a shelter according to the state of the art,
  • the Figures 2 to 8 represent side or perspective views illustrating the different stages of assembly of the shelter according to the invention, and
  • the figure 9 shows in detail the top of the central mast at the moment the frame is being raised.

On a représenté sur la figure 2 un ensemble support 10 amené à proximité d'un socle 12, comprenant un massif en béton 14 et des crosses de scellement 16, sur lequel l'ensemble support 10 va être ériger.We have shown on the figure 2 a support assembly 10 brought close to a base 12, comprising a concrete base 14 and sealing butts 16, on which the support assembly 10 will be erected.

Conformément à l'invention, cet ensemble support comprend un mât central 18 comprenant une cerce 20 destinée à recevoir la périphérie interne d'une toile, une bride 22 fixée dans une partie supérieure, et par exemple au sommet, du mât central 18 et une bague de tension 24. La bride 22 est équipée d'une série de poulies 26 sur chacune desquelles est passé un câble 28, une extrémité de chaque câble étant fixée à la bague de tension 24, l'autre extrémité étant libre.According to the invention, this support assembly comprises a central mast 18 comprising a hoop 20 intended to receive the inner periphery of a fabric, a flange 22 fixed in an upper part, and for example at the top, of the central mast 18 and a 24. The flange 22 is equipped with a series of pulleys 26 on each of which is passed a cable 28, one end of each cable being fixed to the tension ring 24, the other end being free.

Avant la mise en place de l'ensemble support 10 sur son socle, les câbles 28 sont maintenus provisoirement contre le mât central 18 par une fixation, tel qu'un lacage 30. Par ailleurs, une bride de levage 32 est montée provisoirement sur le mât central 18, de préférence à proximité de son centre de gravité.Before placing the support assembly 10 on its base, the cables 28 are temporarily held against the central mast 18 by a fastener, such as a lacing 30. Moreover, a lifting flange 32 is temporarily mounted on the central mast 18, preferably near its center of gravity.

L'ensemble support est d'abord accroché à un câble 34 d'un mât de levage 36 par sa bride de levage 32. On enroule alors le câble 34 à l'aide d'une manivelle 38 jusqu'à ce que l'ensemble support 10 soit à une hauteur suffisante pour pouvoir être pivoté en position verticale (cf. fig 3). On redescend ensuite l'ensemble support 10 sur son socle 12 en déroulant le câble 34. On concoit que cette opération peut être effectuée aisément par deux monteurs, l'un actionnant la manivelle 38 et l'autre faisant pivoter l'ensemble support 10 et l'engageant dans les crosses de scellement 16.The support assembly is first hooked to a cable 34 of a lifting mast 36 by its lifting flange 32. The cable 34 is then wound using a crank 38 until that the support assembly 10 is at a height sufficient to be pivotable in a vertical position (cf. fig 3 ). The support assembly 10 is then lowered back onto its base 12 by unwinding the cable 34. It is understood that this operation can be performed easily by two assemblers, one actuating the crank 38 and the other rotating the support assembly 10 and engaging him in the sealing sticks 16.

On notera que pour cette étape d'érection de l'ensemble support il n'est pas nécessaire de recourir à une grue. L'utilisation d'un mât de levage est également intéressante en ce que sa hauteur peut être égale, voire inférieure, à celle de l'ensemble support de sorte que l'abri peut être monté même dans des endroits où la hauteur libre au-dessus de l'abri est négligeable.Note that for this erection stage of the support assembly it is not necessary to resort to a crane. The use of a hoist mast is also advantageous in that its height may be equal to or even less than that of the support assembly so that the shelter can be mounted even in places where the free height beyond above the shelter is negligible.

Comme représenté sur la figure 3, la toile 40 est mise en place sur le sol avant scellement de l'ensemble support 18, voire avant le pivotement de l'ensemble support 10, l'orifice central 42 de la toile étant en regard du socle.As shown on the figure 3 , the fabric 40 is placed on the floor before sealing of the support assembly 18, or even before the pivoting of the support assembly 10, the central orifice 42 of the fabric facing the base.

L'ensemble support 10 étant scellé, le mât de levage 36 est dégagé, les câbles 28 sont libérés de leur fixation 30 et la bride de levage 32 est retirée.The support assembly 10 being sealed, the lifting mast 36 is disengaged, the cables 28 are released from their attachment 30 and the lifting flange 32 is removed.

L'étape suivante consiste à mettre en place le cadre 44 comme représenté sur la figure 4. Pour cette opération, on apporte les éléments du cadre 44 formés de profilés 46 et de traverses 48. Les profilés 46 sont posés sur des tréteaux 50 et le cadre 44 est monté sur place par fixation, par exemple par boulonnage, des traverses 48 sur les profilés 46 et des extrémités de profilés entre elles.The next step is to set up frame 44 as shown on the figure 4 . For this operation, the elements of the frame 44 made of profiles 46 and crosspieces 48 are provided. The profiles 46 are placed on trestles 50 and the frame 44 is mounted on site by fixing, for example by bolting, sleepers 48 on the rails. sections 46 and ends of profiles between them.

Comme représenté sur la figure 5, l'extrémité libre des câbles 28 est ensuite fixée aux points de fixation 52 du cadre 44 et, après avoir retiré les tréteaux 50, la toile 40 est fixée, d'une part, sur la cerce 20 par sa périphérie interne et, d'autre part, sur le cadre 44 par sa périphérie externe. La toile peut être fixée par tout moyen connu et notamment collage, soudage, clipsage ou autre.As shown on the figure 5 , the free end of the cables 28 is then fixed to the attachment points 52 of the frame 44 and, after removing the trestles 50, the fabric 40 is fixed, on the one hand, on the cerce 20 by its inner periphery and, secondly, on the frame 44 by its outer periphery. The fabric can be fixed by any known means and especially bonding, welding, clipping or other.

On soulève ensuite le cadre 44 jusqu'à la hauteur désirée. Dans cette étape, et contrairement aux procédés selon l'état de la technique, il n'est pas nécessaire d'utiliser une grue.The frame 44 is then raised to the desired height. In this step, and contrary to the methods according to the state of the art, it is not necessary to use a crane.

Il suffit en effet de tirer la bague de tension 24 vers le bas. Ceci peut être réalisé simplement, comme représenté sur la figure 6, en installant un tire-câble 54 à main par exemple de type TIRFOR (Marque déposée) sur une bride 56 provisoire fixée au mât central 18 et de relier la bague de tension 24 au tire-câble 54 par un câble 58 (voir Fig. 9), la cerce 20 comportant au moins une lumière pour le passage du câble 58. Cette installation est effectuée avant la fixation de la toile 40 sur le cadre 44 et la cerce 20, et de préférence avant l'assemblage du cadre 44, comme représenté sur la figure 4.It suffices to pull the tension ring 24 downwards. This can be done simply, as shown on the figure 6 , by installing a cable puller 54 for example of type TIRFOR (registered trademark) on a temporary flange 56 fixed to the central mast 18 and to connect the tension ring 24 to the cable puller 54 by a cable 58 (see FIG. Fig. 9 ), the bar 20 comprising at least one slot for the passage of the cable 58. This installation is performed before the fixing of the fabric 40 on the frame 44 and the bar 20, and preferably before the assembly of the frame 44, as shown. on the figure 4 .

Avant d'actionner le tire-câble 54 pour faire monter le cadre 44, il peut être nécessaire de faire coulisser vers le haut la cerce 20 de manière à ce que, lorsque le cadre 44 atteindra la hauteur désirée, la toile 40 ne soit pas tendue (cf. Fig 7). Alternativement, si on connaît d'avance les positions finales du cadre 44 et de la cerce 20 pour obtenir la tension de toile désirée, on peut placer la cerce 20 dans cette position finale et actionner ensuite le tire-câble 54.Before operating the cable puller 54 to raise the frame 44, it may be necessary to slide up the hoop 20 so that when the frame 44 reaches the desired height, the cloth 40 is not tense (cf. Fig 7 ). Alternatively, if the final positions of the frame 44 and the hoop 20 are known in advance in order to obtain the desired fabric tension, the hoop 20 can be placed in this final position and then actuate the cable puller 54.

Dans le premier cas, tel que représenté sur la figure 7, après avoir verrouillé la bague de tension 24 sur le mât central 18, on utilise le tire-câble 54 pour faire descendre la cerce 20 jusqu'à ce que la toile 40 soit tendue correctement, et on verrouille la position de la cerce 20 sur le mât central 18.In the first case, as shown on the figure 7 after having locked the tension ring 24 on the central mast 18, the cable puller 54 is used to make down the hoop 20 until the fabric 40 is stretched correctly, and locks the position of the hoop 20 on the central mast 18.

Le montage est maintenant terminé. On peut alors retirer le tire-câble 54 et la bride 56 provisoires de l'ensemble support 10. L'abri monté présente l'aspect illustré sur la figure 8.The editing is now complete. The temporary cable puller 54 and flange 56 can then be removed from the support assembly 10. The mounted shelter has the appearance illustrated in FIG. figure 8 .
