ELEMENTS DE ωuVERTURE GONFLABLES ET ENSEMBLE OBTENU PAR LEUR JUXTAPOSITION SUR UNE STRUCTURE PORTANTE INFLATABLE OPENING ELEMENTS AND ASSEMBLY OBTAINED BY THEIR JUXTAPOSITION ON A SUPPORTING STRUCTURE
DESCRIPTIONDESCRIPTION
L'invention concerne des éléments de couverture gonflables du genre:The invention relates to inflatable cover elements such as:
- comportant deux films souples superposés, en matière plastique, remplis d'air, et des cordes de tension associées auxdits films;- comprising two superimposed flexible films, made of plastic, filled with air, and tension cords associated with said films;
- reposant sur une structure portante apte à soutenir au moins deux éléments de couverture juxtaposés;- resting on a supporting structure capable of supporting at least two juxtaposed cover elements;
- destinés à abriter un volume bien déterminé à usage agricole, horticole, sportif ou autre;- intended to house a clearly defined volume for agricultural, horticultural, sporting or other purposes;
Les ensembles connus destinés à constituer des abris, plus particulièrement pour les cultures de toutes natures, sont généralement de deux types :The known assemblies intended to constitute shelters, more particularly for cultures of all kinds, are generally of two types:
- ceux qui associent des couvertures en verre (simple ou double paroi) et des structures portantes (en bois ou métalliques) qui sont d'un coût très élevé et qui sont limités en volume d'air disponible;- those which combine glass covers (single or double wall) and load-bearing structures (wood or metal) which are very expensive and which are limited in the volume of air available;
-ceux qui associent des couvertures en film plastique (simple ou double, gonflable ou non) et des structures tubulaires (généralement métalliques) qui sont relativement onéreux par rapport au coût de la couverture et qui sont également limités en volume d'air disponible.-those which combine plastic film covers (single or double, inflatable or not) and tubular structures (generally metallic) which are relatively expensive compared to the cost of the cover and which are also limited in the volume of air available.
De nombreux ensembles comportant des couvertures gonflables et des structures portantes ont fait l'objet de divers brevets (US-4805355, FR-2544213, FR-2204744).Numerous assemblies comprising inflatable covers and supporting structures have been the subject of various patents (US-4805355, FR-2544213, FR-2204744).
Malheureusement, de tels ensembles ne sont pas adaptés aux cultures sous- abri qui nécessitent essentiellement :Unfortunately, such sets are not suitable for cover crops, which essentially require:
- des grands volumes d'air pour diminuer les carences en C02 et pour mieux réguler les températures (avec réduction des échanges) ; - des structures "légères" qui diminuent les lignes de contact avec la couverture (abrasion, brûlure...) et qui suppriment les ombres portées sur les cultures (plus grande luminosité);- large volumes of air to reduce C02 deficiencies and to better regulate temperatures (with reduced exchanges); - "light" structures which reduce the lines of contact with the cover (abrasion, burns, etc.) and which remove the shadows cast on the crops (greater luminosity);
- de très grandes portées avec un minimun de structure pour une plus grande liberté d'exploitation (travail facilité); - de grandes hauteurs pour une plus grande variété de cultures (arboriculture fruitière par exemple);- very large spans with a minimum of structure for greater freedom of operation (easier work); - great heights for a greater variety of crops (fruit trees for example);
- une grande résistance aux vents violents et réguliers; - un prix de revient relativement bas et en rapport avec les marges bénéficiaires des exploitations agricoles et horticoles actuelles et futures;- great resistance to strong and regular winds; - a relatively low cost price and in relation to the profit margins of current and future agricultural and horticultural operations;
- une bonne aération.- good ventilation.
L'ensemble objet de la présente invention répond à toutes ces exigences.The object of the present invention meets all these requirements.
Elle concerne à cet effet des éléments de couverture gonflables, du genre comportant deux films souples superposés et des cordes de tension associées > destinés à reposer sur une structure portante et qui se caractérisent essentiellement en ce que : a) les deux films souples superposés appartiennent à une même gaine fermée ; b) les cordes de tension sont positionnées longitudinalement à l'intérieur de la gaine :To this end, it relates to inflatable cover elements, of the type comprising two superimposed flexible films and associated tension cords> intended to rest on a bearing structure and which are essentially characterized in that: a) the two superimposed flexible films belong to the same closed sheath; b) the tension ropes are positioned longitudinally inside the sheath:
- pour deux d'entre elles, aux extrémités opposées de celle-ci; - pour les autres, à intervalles réguliers entre lesdites deux cordes d'extrémité; c) lesdites cordes de tension sont placées à l'intérieur de fourreaux obtenus par soudage linéaire longitudinal des deux films superposés de la gaine à raison d'une ligne de soudure pour les fourreaux d'extrémité et de deux lignes de soudure pour les fourreaux intermédiaires (10).- for two of them, at the opposite ends thereof; - for the others, at regular intervals between said two end cords; c) said tension cords are placed inside sheaths obtained by longitudinal linear welding of the two superimposed films of the sheath at the rate of one weld line for the end sleeves and two weld lines for the intermediate sleeves (10).
La structure portante se caractérise essentiellement en ce qu'elle est constituée de poteaux reposant sur le sol et de traverses hautes, reposant sur lesdits poteaux, aptes à soutenir au moins deux éléments de couverture juxtaposés. L'ensemble selon l'invention se caractérise également par :The supporting structure is essentially characterized in that it is made up of posts resting on the ground and high crosspieces, resting on said posts, capable of supporting at least two juxtaposed covering elements. The assembly according to the invention is also characterized by:
- ses moyens d'ancrage dans le sol (film et cordes en particulier);- its means of anchoring in the ground (film and ropes in particular);
- l'utilisation de gaines de grandes largeurs (3,30 m par exemple) utilisant des films qui possèdent un très haut pouvoir de diffusion de la lumière et qui permettent une bonne régulation des échanges thermiques entre l'extérieur et l'intérieur.- the use of large width ducts (3.30 m for example) using films which have a very high power of light diffusion and which allow a good regulation of the heat exchanges between outside and inside.
L'association de l'air souflé dans la double paroi de la couverture et des cordes de tension, assure une bonne tenue mécanique à la couverture. Les moyens d'ancrage dans le sol du film de couverture et des cordes de tension, assurent à l'ensemble "couverture et structure" également une bonne tenue mécanique. La couverture obtenue est tendue et très légère.The association of the blown air in the double wall of the cover and the tension cords, ensures good mechanical resistance to the cover. The anchoring means in the ground of the cover film and the tension cords, ensure that the "cover and structure" assembly also has good mechanical strength. The blanket obtained is stretched and very light.
Les caractéristiques et les avantages de l'invention vont apparaître plus clairement à la lecture de la description détaillée qui suit d'au moins un mode de réalisation préféré de celle-ci donné à titre d'exemple non limitatif et représenté aux dessins annexés. Sur ces dessins :The characteristics and advantages of the invention will appear more clearly on reading the following detailed description of at least one preferred embodiment of the latter given by way of non-limiting example and shown in the accompanying drawings. In these drawings:
- la figure 1 est une vue en perspective partielle de l'élément de couverture;- Figure 1 is a partial perspective view of the cover element;
- la figure 2 est une vue en perspective de la jonction existant entre deux éléments de couverture consécutifs;- Figure 2 is a perspective view of the junction between two consecutive cover elements;
- la figure 3 est une vue en perspective de l'ensemble comprenant des éléments de couverture juxtaposés et leur structure portante;- Figure 3 is a perspective view of the assembly comprising juxtaposed cover elements and their supporting structure;
- la figure 4 est une vue de profil en coupe dudit ensemble;- Figure 4 is a sectional side view of said assembly;
- la figure 5 est une vue de dessus dudit ensemble. Les éléments de couverture gonflables (1) représentés aux figures 1 et 2 sont du genre :- Figure 5 is a top view of said assembly. The inflatable cover elements (1) shown in Figures 1 and 2 are of the type:
- comportant deux films souples superposés (2,3), en matière plastique, remplis d'air, et des cordes de tension (4,5) associées auxdits films;- comprising two superimposed flexible films (2,3), made of plastic, filled with air, and tension cords (4,5) associated with said films;
- reposant sur une structure portante (6) apte à soutenir au moins deux éléments de couverture (1) juxtaposés;- resting on a supporting structure (6) capable of supporting at least two juxtaposed cover elements (1);
- destinés à abriter un volume bien déterminé à usage agricole, horticole, sportif ou autre.- intended to house a clearly defined volume for agricultural, horticultural, sporting or other purposes.
Lesdits éléments de couverture présentent les particularités nouvelles et originales suivantes : - les deux films souples superposés (2,3) appartiennent à une même gaine fermée;Said cover elements have the following new and original features: - the two superimposed flexible films (2,3) belong to the same closed sheath;
- les cordes de tension (4,5) sont positionnées longitudinalement à l'intérieur de la gaine :- the tension ropes (4,5) are positioned longitudinally inside the sheath:
.. pour deux d'entre elles (4), aux extrémités opposées de celle-ci; .. pour les autres (5), à intervalles réguliers entre lesdites deux cordes d'extrémité (4);.. for two of them (4), at the opposite ends thereof; .. for the others (5), at regular intervals between said two end cords (4);
- lesdites cordes de tension (4,5) sont placées à l'intérieur de fourreaux (9,10) obtenus par soudage linéaire longitudinal des deux films superposés (2,3) de la gaine à raison d'une ligne de soudure (11) pour les fourreaux d'extrémité (9) et de deux lignes de soudure (12) pour les fourreaux intermédiaires (10).- Said tension cords (4,5) are placed inside sheaths (9,10) obtained by longitudinal linear welding of the two superimposed films (2,3) of the sheath at the rate of a weld line (11 ) for the end sleeves (9) and two weld lines (12) for the sleeves intermediaries (10).
Selon la réalisation préférée de l'invention, dans le cas de l'utilisation de gaines de grandes largeurs (3,30 mètres par exemple), les cordes de tension intermédiaires sont au nombre de deux. II résulte que, dans ce cas, les lignes de soudure longitudinales (11,12) sont au nombre de six.According to the preferred embodiment of the invention, in the case of the use of sheaths of large widths (3.30 meters for example), there are two intermediate tension cords. It follows that, in this case, the longitudinal weld lines (11,12) are six in number.
Les bords latéraux des éléments de couverture (1) comportent des moyens (13) assurant la liaison des éléments de couverture consécutifs entre eux de manière fixe ou de manière modifiable sur commande. Les moyens (13) de liaison de deux éléments de couverture (1) consécutifs peuvent être associés à un moyen (14,15) de réglage de l'écartement des bords latéraux desdits éléments de couverture (1) de manière à constituer l'ouvrant d'aération de l'ensemble "éléments (1) et structure (6)". Le moyen (14,15) de réglage de l'écartement des bords latéraux de deux éléments de couverture (1) consécutifs est du type tige filetée (14) et écrou (15) solidaire d'un des bords latéraux. Il peut être de tout autre type.The lateral edges of the covering elements (1) comprise means (13) ensuring the connection of the consecutive covering elements with one another in a fixed manner or in a modifiable manner on command. The means (13) for connecting two consecutive covering elements (1) can be associated with a means (14,15) for adjusting the spacing of the lateral edges of said covering elements (1) so as to constitute the opening ventilation of the assembly "elements (1) and structure (6)". The means (14,15) for adjusting the spacing of the lateral edges of two consecutive covering elements (1) is of the threaded rod (14) and nut (15) type secured to one of the lateral edges. It can be of any other type.
L'ensemble représenté aux figures 3, 4 et 5, comporte une structure portante (6) et des éléments de couverture (1).The assembly shown in Figures 3, 4 and 5, comprises a supporting structure (6) and cover elements (1).
La structure portante (6) comporte essentiellement des poteaux (7) reposant sur le sol et des traverses hautes (8), reposant sur lesdits poteaux, aptes à soutenir au moins deux éléments de couverture (1) juxtaposés. Les autres particularités dudit ensemble sont :The supporting structure (6) essentially comprises posts (7) resting on the ground and high crosspieces (8), resting on said posts, capable of supporting at least two juxtaposed covering elements (1). The other particularities of this set are:
- les extrémités (16) des films (2,3) de couverture sont ancrées dans le sol;- The ends (16) of the cover films (2,3) are anchored in the ground;
- les extrémités (17) des cordes de tension (4,5) sont ancrées dans le sol.- The ends (17) of the tension ropes (4,5) are anchored in the ground.
Il comporte en outre une tubulure (18) de distribution de l'air puisé qui alimente chaque compartiment (19) de chaque élément de couverture (1). Les éléments de couverture (1) sont placés perpendiculairement à l'axe longitudinal de l'ensemble selon l'invention.It further comprises a manifold (18) for distributing the forced air which feeds each compartment (19) of each covering element (1). The cover elements (1) are placed perpendicular to the longitudinal axis of the assembly according to the invention.
On obtient ainsi une structure tendue très légère. Les cordes sont préférentiellement des câbles textiles à base de fibres aramides ou analogue dont la tenue n'est pas modifiée ni par l'humidité, ni par la tension. De telles fibres procurent une résistance supérieure à celle de l'acier avec un poids très inférieur. Elles présentent en outre, l'avantage d'être isolantes ce qui évite la formation de points chauds. Il n'existe aucune liaison fixe constituant des zones de déchirure entre les cordes et la gaine de couverture. La gaine peut ainsi se déformer en fonction des sollicitations auxquelles elle est soumise. La couverture reste ainsi fondamentalement souple. La pression à l'intérieur de la gaine est relativement basse et sert simplement à répartir les surpressions ponctuelles tout en constituant un isolant thermique. Le film plastique est préférentiellement constitué par une gaine en polyéthylène complexe résistant bien aux rayonnements U.V. Il s'agit d'un film multicouches incluant du polyéthylène et de 1"'EVA".A very light tensile structure is thus obtained. The cords are preferably textile cables based on aramid fibers or the like, the behavior of which is not modified either by humidity or by tension. Such fibers provide superior strength than that of steel with a much lower weight. They also have the advantage of being insulating, which prevents the formation of hot spots. There is no fixed connection constituting tear zones between the cords and the covering sheath. The sheath can thus deform depending on the stresses to which it is subjected. Coverage thus remains fundamentally flexible. The pressure inside the sheath is relatively low and is used simply to distribute the point pressures while constituting a thermal insulator. The plastic film is preferably constituted by a complex polyethylene sheath resistant well to UV radiation. It is a multilayer film including polyethylene and 1 "EVA".
Le procédé de réalisation des éléments de couverture consiste à réaliser sur une gaine à plat et en continu les soudures longitudinales des fourreaux.The method for producing the covering elements consists in carrying out the longitudinal welds of the sleeves on a flat sheath and continuously.
Les cordes sont ensuite introduites lors de l'installation, élément par élément, après découpe de celui-ci à la longueur désirée.The strings are then introduced during installation, element by element, after cutting it to the desired length.
Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés pour lesquels on pourra prévoir d'autres variantes en particulier dans :Of course, the invention is not limited to the embodiments described and shown for which other variants can be provided, in particular in:
- la nature et les largeurs des gaines;- the nature and widths of the sheaths;
- la nature et le nombre de cordes de tension;- the nature and number of tension strings;
- la nature et la configuration des poteaux et des traverses entrant dans la composition de la structure; - les types de moyens de liaison des éléments de couverture entre eux qui peuvent être par exemple du type bande de renfort (13) prenant en "sandwich" les bords latéraux des éléments de couverture (1) et pourvus, dans le cas d'une liaison non ouvrante, de moyens d'accrochage et, dans le cas d'une liaison ouvrante, de moyens (14,15,20), du type vis-écrou, où (15) est l'écrou solidaire de la bande (13) appartenant à l'un des éléments de couverture et (20) est le support de l'extrémité de la tige filetée (14) solidaire de la bande (13) appartenant à l'autre élément de couverture, ladite tige filetée constituant la manivelle d'ouvrant. - the nature and configuration of the posts and sleepers used in the composition of the structure; - the types of means for connecting the covering elements together, which may for example be of the reinforcing strip type (13) sandwiching the lateral edges of the covering elements (1) and provided, in the case of a non-opening connection, hooking means and, in the case of an opening connection, means (14,15,20), of the screw-nut type, where (15) is the nut secured to the strip (13 ) belonging to one of the cover elements and (20) is the support for the end of the threaded rod (14) integral with the strip (13) belonging to the other cover element, said threaded rod constituting the crank opening.
