De tels équipements sont généralement réalisés par l'assemblage d'une structure porteuse métallique et de vitres en verre ou en polycarbonate .  Such equipment is generally made by assembling a metal support structure and glass panes or polycarbonate.
État de la technique State of the art
On connaît dans l'état de la technique le brevet français FR995184 décrivant une construction démontable constituée de plusieurs pièces reliées entre elles d'une manière amovible pour réaliser une serre de culture qui soit économique et qui peut être montée et démontée aisément. Des fermes en aluminium ou métal léger présentant une section transversale en forme de T sont assemblées par des attaches. Un cadre en bois référencé 12 assure la liaison longitudinale entre deux fermes adjacentes .  It is known in the state of the art the French patent FR995184 describing a dismountable construction consisting of several parts interconnected in a removable manner to achieve a culture greenhouse that is economical and can be mounted and dismounted easily. Aluminum or light metal trusses having a T-shaped cross-section are joined by fasteners. A referenced wooden frame 12 provides the longitudinal connection between two adjacent farms.
Le brevet français FR943248 décrit un autre exemple de serre démontable, dont les surfaces situées de part et d'autre de son faite sont constituées chacune par au moins un panneau formé de chevrons perpendiculaires audit faîte et dont les extrémités supérieures, reliées par une pièce de bois formant demi-poutre faîtière. The French patent FR943248 describes another example of a removable greenhouse, whose surfaces located on either side of its fact are each constituted by at least one panel formed of chevrons perpendicular to said ridge and whose upper ends, connected by a piece of wood forming ridge half-beam.
Le brevet US4437273 décrit un système en treillis pour la construction du cadre d'une habitation comprenant: une pluralité de fermes préassemblées planes et rigides, lesdites fermes étant espacées et s'étendant dans des plans sensiblement parallèles, au moins deux fermes adjacentes de ladite pluralité de fermes étant sensiblement identiques les unes aux autres, lesdites au moins deux fermes adjacentes comprenant chacune une solive de plancher allongée. US4437273 discloses a lattice system for the construction of the frame of a dwelling comprising: a plurality of flat and rigid pre-assembled trusses, said wherein the trusses are spaced apart and extending in substantially parallel planes, at least two adjacent trusses of said plurality of trusses being substantially identical to each other, said at least two adjacent trusses each comprising an elongated floor joist.
Le brevet chinois CN105453948 concerne un cadre de remise à effet de serre à structure combinée en béton de bambou comprenant des fermes en franges et des poutres en arc. La poutre arquée est constituée d'un matériau de section en bambou de section transversale en forme de T. L'extrémité supérieure de la ferme à franges est munie d'une rainure en forme de T. La poutre arquée est reliée de manière fixe à la rainure en forme de T de la ferme à franges. Le treillis à franges, le matériau de coupe en bambou de section transversale en forme de T et le treillis à franges sont utilisés pour former un cadre de hangar à cadre unique .  Chinese Patent CN105453948 relates to a bamboo concrete composite frame greenhouse comprising fringed trusses and arched beams. The arched beam consists of a bamboo section material of T-shaped cross-section. The upper end of the fringe farm is provided with a T-shaped groove. The arched beam is fixedly connected to the T-shaped groove of the fringe farm. The fringed mesh, the T-shaped cross section bamboo cutting material and the fringed mesh are used to form a single frame shed frame.
Inconvénients de l'art antérieur Disadvantages of prior art
Les solutions de l'art antérieur ne sont pas totalement satisfaisantes car elles se traduisent par des structures relativement lourdes, dont l'assemblage est complexe car il nécessite la réalisation d'une armature autoporteuse, puis la pose des panneaux de polycarbonate sur cette armature autoporteuse, en procédant à un ajustement précis de chaque panneau sur la fenêtre destinée à le recevoir. The solutions of the prior art are not completely satisfactory because they result in relatively heavy structures, the assembly is complex because it requires the realization of a self-supporting armature, and the installation of polycarbonate panels on this self-supporting armature , by making a precise adjustment of each panel on the window intended to receive it.
Par ailleurs, le taux de dilatation de la structure est supérieur au taux de dilatation des panneaux de polycarbonate, ce qui peut conduire à des déformations des panneaux en polycarbonate par rapport à la structure en bois.  Furthermore, the expansion rate of the structure is greater than the expansion ratio of the polycarbonate panels, which can lead to deformations of the polycarbonate panels relative to the wooden structure.
Solution apportée par l'invention Solution provided by the invention
Afin de remédier à ces inconvénients, l'invention concerne selon son acception la plus générale une serre constituée par une armature en bois formée par des éléments de charpente en bois et des panneaux de polycarbonate supportés par lesdits montants en bois pour former des murs et un toit, caractérisée en ce que ladite armature est constituée par une pluralité de fermes en bois reliées deux à deux par lesdits panneaux en polycarbonate, à l'exclusion de traverses longitudinales. Lesdites fermes ne sont pas reliées par des traverses longitudinales à l'exception de la liaison assurée par 1 ' embase . In order to remedy these drawbacks, the invention relates, in its most general sense, to a greenhouse constituted by a wooden frame formed by elements of wood frame and polycarbonate panels supported by said wooden uprights to form walls and a roof, characterized in that said frame is constituted by a plurality of wooden trusses connected two by two by said polycarbonate panels, to the exclusion of longitudinal sleepers. Said trusses are not connected by longitudinal crosspieces with the exception of the connection provided by one base.

Description d'un premier exemple de réalisation Description of a first exemplary embodiment
La serre représentée en figure 1 selon un premier exemple de réalisation est formée par une armature constituée par une pluralité de fermes (1 à 9).  The greenhouse shown in Figure 1 according to a first embodiment is formed by an armature constituted by a plurality of farms (1 to 9).
Chaque ferme (1 à 9) est formée par un assemblage de deux montants verticaux (10, 11) présentant une section transversale rectangulaire, reliés par deux arbalétriers (12, 13) inclinés et reliés par un lien de faîtage (14).  Each farm (1 to 9) is formed by an assembly of two vertical uprights (10, 11) having a rectangular cross section, connected by two rafters (12, 13) inclined and connected by a ridge link (14).
Ces éléments de charpentes (10 à 13) sont constitués par des pièces en bois de section 70x28 mm, en mélèze imputrescible classe 3 selon la norme NF EN 335-1 à 3 créée par l'institut technologique Forêt, Cellulose, Bois-construction et Ameublement (FCBA) .  These frame elements (10 to 13) consist of wooden pieces of section 70x28 mm, rustproof larch class 3 according to standard NF EN 335-1 to 3 created by the forest technology institute, Cellulose, Bois-construction and Furniture (FCBA).
Typiquement, la hauteur des montants verticaux (10, 11) est de 1,5 mètres, et la hauteur au niveau du faîtage est de 2,3 mètres . La distance entre deux fermes consécutives est de 49 centimètres . Typically, the height of the uprights (10, 11) is 1.5 meters, and the height at the ridge is 2.3 meters. The distance between two consecutive farms is 49 centimeters.
Les fermes ( 1 à 9 ) sont indépendantes et ne sont pas reliées entre elles par des éléments longitudinaux.  The trusses (1 to 9) are independent and are not interconnected by longitudinal elements.
Elles sont engagées dans une embase périphérique (20) formant un cadre rectangulaire assurant la liaison au sol.  They are engaged in a peripheral base (20) forming a rectangular frame providing the connection to the ground.
La liaison entre deux fermes consécutives est assurée par les panneaux (30) en polycarbonates pouvant recouvrir plusieurs fermes. A titre d'exemple, un panneau (30) présente une largeur de 1,5x2 m pour relier et recouvrir latéralement cinq fermes (1 à 5).  The connection between two consecutive farms is provided by panels (30) made of polycarbonates that can cover several farms. For example, a panel (30) has a width of 1.5x2 m to connect and cover laterally five farms (1 to 5).
Chaque panneau (30) en polycarbonate présente une épaisseur de 2 millimètres, préférentiellement entre 1,5 et 5 millimètres. Il présente des alignements de perçages espacés de 316 millimètres, les alignements étant eux-mêmes espacés d'une longueur correspondant à la distance entre deux fermes consécutives, soit 49 centimètres dans l'exemple visé.  Each polycarbonate panel (30) has a thickness of 2 millimeters, preferably between 1.5 and 5 millimeters. It has drill alignments spaced 316 millimeters, the alignments being themselves spaced a length corresponding to the distance between two consecutive farms, or 49 centimeters in the example.
Les perçages des panneaux présentent une section de 6 millimètres, pour permettre la fixation du panneau (30) sur un montant vertical par des vis d'une section de 4 millimètres. Les vis sont complétées par une rondelle en élastomère pour assurer une liaison mécanique étanche.  The holes of the panels have a section of 6 millimeters, to allow the fixing of the panel (30) on a vertical upright by screws with a section of 4 millimeters. The screws are completed by an elastomer washer to ensure a tight mechanical connection.
Description d'un deuxième exemple de réalisation Description of a second exemplary embodiment
La figure 2 représente une variante de réalisation qui se distingue de la variante décrite précédemment par le fait que la liaison entre les montants verticaux (10, 11) sont reliés non pas par deux arbalétriers assemblés au niveau de la ligne faîtière, mais par un seul arbalétrier (14) en bois arquée. FIG. 2 shows an alternative embodiment that differs from the variant described above in that the connection between the vertical uprights (10, 11) are connected not by two assembled rafters at the ridge line, but by a single archway (14) made of arched wood.
Détail des assemblages des éléments de charpente Detail of assemblies of structural members
Les éléments de charpente sont reliés par des ferrures dont la figure 3 représente un exemple. Elles sont formées par une pièce métallique (30) coudée en acier galvanisé d'une épaisseur de 3 millimètres et d'une largeur de 50 millimètres pour des montants (10, 12) d'une section de 70 millimètres. La pièce (30) présente une forme de boomerang, les deux ailes (31, 32) étant écartées de 30°. The frame members are connected by fittings, Figure 3 shows an example. They are formed by a metal piece (30) bent galvanized steel with a thickness of 3 millimeters and a width of 50 millimeters for amounts (10, 12) of a section of 70 millimeters. The piece (30) has a boomerang shape, the two wings (31, 32) being spaced apart by 30 °.
Chaque aile (31, 32) présente des perçages (33, 34 ; Each wing (31, 32) has bores (33, 34;
35 , 36 ) . 35, 36).
Les ferrures (30) sont engagées dans une fente médiane prévue à l'extrémité des pièces (10, 12) à assembler et fixées par des écrous-relieurs traversant la pièce à assembler.  The fittings (30) are engaged in a median slot provided at the end of the parts (10, 12) to be assembled and fixed by bookbinding nuts passing through the part to be assembled.
Ferrure de liaison entre les montants et l'embaseConnecting piece between the uprights and the base
La figure 4 représente une vue d'une ferrure (35) de liaison entre les montants verticaux (10, 11) et l'embase (30). Figure 4 shows a view of a fitting (35) connecting the vertical uprights (10, 11) and the base (30).
Elle est formée par une pièce métallique pliée en acier galvanisé d'une épaisseur de 3 millimètres présentant sur une de ces ailes (36) un perçage oblong (37) décalé par rapport à l'axe. Cette aile (36) vient s'insérer dans une fente latérale prévue sur le montant vertical (10). L'aile inférieure (38) est vissée sur l'embase.  It is formed by a bent piece of galvanized steel with a thickness of 3 millimeters having on one of these wings (36) an oblong hole (37) offset with respect to the axis. This wing (36) is inserted into a lateral slot provided on the vertical upright (10). The lower wing (38) is screwed onto the base.
Aération de la serre Aeration of the greenhouse
Pour assurer l'aération de la serre, les panneaux de faîtage (40) présentent une bordure périphérique libre, non fixée sur les fermes, pour permettre par déformation le déplacement entre une position fermée et une position où le bord est écarté de la ligne faîtière. To ensure aeration of the greenhouse, the ridge panels (40) have a free peripheral edge, not fixed on the trusses, to allow by deformation the movement between a closed position and a position where the edge is separated from the ridge line .
Le panneau de polycarbonate (40) présente le long de son bord de faîtage un tronçon de faîtière en bois (41) dont la section correspond à l'encoche formée sur les fermes au niveau de la ligne de faîtage. Lorsque la serre est fermée, ce tronçon de faîtière en bois (41) vient se loger dans ces encoches et le bord du panneau (40) vient au contact avec le panneau (42) complémentaire . Un vérin (43) commande le déplacement de ce tronçon de faîtière (41) dans une direction écartée de la ligne faîtière, ce qui crée une déformation de la bordure libre du panneau de polycarbonate (40), pour libérer une fente d'aération. The polycarbonate panel (40) has along its ridge edge a section of wooden ridge (41) whose section corresponds to the notch formed on the trusses at the ridge line. When the greenhouse is closed, this section of wooden ridge (41) is housed in these notches and the edge of the panel (40) comes into contact with the panel (42) complementary. A jack (43) controls the movement of this ridge section (41) in a direction away from the ridge line, thereby deforming the free edge of the polycarbonate panel (40) to release a vent slot.
Assemblage de la serre Assembly of the greenhouse
Pour construire la serre, on commence par assembler les fermes (1 à 9) à plat, au sol, ainsi que l'embase (20). To build the greenhouse, we first assemble the farms (1 to 9) flat on the ground, and the base (20).
On positionne ensuite deux fermes médianes (2, 3) correspondant au milieu d'un panneau de polycarbonate (30) et on procède à un vissage provisoire du panneau (30), avec les vis d'extrémité de l'alignement, sur les deux fermes (2, 3). A ce stade, les fermes ne sont pas encore fixées à l'embase.  Two middle trusses (2, 3) corresponding to the middle of a polycarbonate panel (30) are then positioned and the panel (30) is temporarily screwed together with the end screws of the alignment on both sides. farms (2, 3). At this stage, the trusses are not yet attached to the base.
On pose ensuite le panneau de polycarbonate correspondant au mur opposé, en le vissant provisoirement avec les vis aux extrémités de l'alignement.  The polycarbonate panel corresponding to the opposite wall is then laid, screwing it temporarily with the screws at the ends of the alignment.
On procède de même pour les tronçons de mur suivants pour assembler toutes les fermes avec les panneaux de mur.  The same procedure is followed for the following wall sections to assemble all the trusses with the wall panels.
On positionne ensuite les panneaux de toit, en les vissant provisoirement avec les vis d'extrémité.  The roof panels are then positioned by temporarily screwing them with the end screws.
L'étape suivante consiste à finaliser la fixation des panneaux de polycarbonate sur les fermes, ces panneaux formant la liaison structurelle longitudinale des fermes, contrairement aux solutions de l'art antérieur où la rigidité longitudinale est assurée par des traverses.  The next step is to finalize the fixing of the polycarbonate panels on the trusses, these panels forming the longitudinal structural connection of the trusses, unlike the solutions of the prior art where the longitudinal rigidity is provided by cross members.
On finalise le serrage de la totalité des vis.  We finalize the tightening of all the screws.
Ensuite, on positionne l'armature ainsi réalisée sur l'embase (20) par un glissement, puis on fixe les ferrures de liaison entre les montants (10,12) avec l'embase et on finalise le vissage.  Then, the reinforcement thus formed is positioned on the base (20) by sliding, then the connecting fittings between the uprights (10, 12) are fixed with the base and the screwing is completed.
Les panneaux de polycarbonate recouvrent latéralement l'embase, et sont ensuite fixés par des vissages traversant la bordure inférieure des panneaux de mur.  The polycarbonate panels laterally cover the base, and are then secured by screw connections passing through the bottom edge of the wall panels.
