Description

PROCEDE D'ENCASTREMENT D'UNE STRUCTURE SOLAI RE  METHOD FOR RECOVERING A SOLAR STRUCTURE
L'invention concerne le domaine des panneaux solaires suiveurs, c'est-à- dire dont leur orientation peuvent changer en fonction de la variation de l'ensoleillement durant la journée et durant l'année. The invention relates to the field of solar tracking panels, that is to say whose orientation can change depending on the variation of sunshine during the day and during the year.
L'invention concerne plus particulièrement l'encastrement dans le sol des structures de support des panneaux solaires, appelées par la suite « structure solaire ». The invention relates more particularly to the embedding in the ground of the support structures of the solar panels, hereinafter called "solar structure".
Arrière plan de l'invention Background of the invention
Communément, un panneau solaire selon l'état de la technique, illustré par exemple à la figure 2, comprend une structure de support 2 (appelée par la suite « structure solaire ») qui permet le support d'un élément (non représenté) portant un panneau de traitement des rayons solaires (généralement constitué d'une pluralité de cellules photovoltaïques). Le panneau de traitement peut être monté fixe. En variante, le panneau solaireCommonly, a solar panel according to the prior art, illustrated for example in Figure 2, comprises a support structure 2 (hereinafter referred to as "solar structure") which allows the support of an element (not shown) bearing a solar ray treatment panel (generally consisting of a plurality of photovoltaic cells). The treatment panel can be fixed mounted. Alternatively, the solar panel
I comprend également un système d'actionnement du panneau de traitement des rayons solaire permettant de contrôler l'inclinaison générale dudit panneau de traitement autour d'un axe X par rapport au sol. I also includes an actuation system of the solar ray treatment panel for controlling the overall inclination of said treatment panel about an axis X with respect to the ground.
C'est pourquoi il est important que la structure solaire 2 soit fermement encastrée dans la bonne position afin que le contrôle de l'inclinaison générale du panneau solaire ne soit pas faussé par un mauvais positionnement de la structure solaire 2. Therefore it is important that the solar structure 2 is firmly embedded in the correct position so that the control of the overall inclination of the solar panel is not distorted by a poor positioning of the solar structure 2.
II est connu dans l'état de la technique un procédé d'encastrement des structures solaires qui comprend les étapes suivantes : It is known in the state of the art a method of embedding solar structures which comprises the following steps:
réalisation de trous dans un sol afin d'y encastrer une ou plusieurs structure(s) solaire(s),  making holes in a ground so as to embed one or more solar structures,
coulage d'une couche de béton afin de réaliser une dalle de béton en y encastrant des moyens d'attache et de réglage d'une structure solaire dans une position prédéterminée, après un temps de séchage adéquat (prise du béton), mise en place sur les moyens d'attache et de réglage ou sur la dalle de béton d'une structure solaire, pouring a layer of concrete to make a concrete slab by embedding means for attaching and adjusting a solar structure in a predetermined position, after a suitable drying time (setting of the concrete), placing on the means of attachment and adjustment or on the concrete slab of a solar structure,
réglage du positionnement spatial de la structure solaire à l'aide des moyens d'attache et de réglage.  adjusting the spatial positioning of the solar structure by means of attachment and adjustment means.
Cependant des critiques ont été émises concernant un tel procédé d'encastrement de structure solaire. En effet, le béton ayant une masse volume importante et une rhéologie le rendant peu fluide, l'étape de coulage peut apporter des problèmes de déstabilisation des moyens d'attache et de réglage de la structure solaire qui peuvent donc être déplacés hors de la position prédéterminée. En conséquence, après le séchage de la couche de béton, la structure solaire encastrée dans le sol avec un mauvais positionnement peut engendrer des erreurs d'inclinaison dans la commande du panneau solaire, ce qui engendre une dégradation du rendement du panneau solaire, notamment lors d'un mauvais alignement en hauteur de la structure porteuse portant le panneau solaire. However, criticisms have been made about such a solar structure embedding method. In fact, since the concrete has a large volume and a rheology which makes it not very fluid, the casting step can bring destabilizing problems to the fastening and adjustment means of the solar structure, which can therefore be moved out of the position. predetermined. Consequently, after the drying of the concrete layer, the solar structure embedded in the ground with a bad positioning can cause tilt errors in the control of the solar panel, which leads to a degradation of the performance of the solar panel, especially when misalignment in height of the supporting structure carrying the solar panel.
Ainsi, un but de la présente invention est de fournir un procédé d'encastrement d'une structure solaire rapide et peu coûteux qui permette d'éviter tout mauvais placement de la structure solaire lors de l'encastrement de cette dernière, notamment lors de l'étape de coulage de la couche de béton. Résumé de l'invention Thus, an object of the present invention is to provide a method for embedding a fast and inexpensive solar structure that makes it possible to avoid any mispositioning of the solar structure during the embedding of the latter, in particular during casting step of the concrete layer. Summary of the invention

Chacun des sommets reçoit une extrémité de pied d'ancrage de la structure solaire 2 à assembler. Le gabarit de montage comporte une barre médiane 25 traversant la base polygonale 25. Perpendiculairement à la base polygonale 25, deux montants 22 et 23 s'élèvent de la barre médiane 25 aux extrémités libres desquelles est fixée une barre de renfort 21 , ici sensiblement parallèle à la barre médiane 24. A chacune des extrémités de la barre de renfort 21 , des mors 26 et 27 sont prévus. Ces mors 26 et 27 permettent de maintenir, en vue de l'assemblage de la structure solaire 2, les pieds d'ancrage 5a, 5b et 5c. Les mors 26 et 27 sont positionnés de sorte à maintenir une position spatiale relative entre les différents pieds d'ancrage de la structure solaire 2 à assembler. Un mors 28 supplémentaire est prévu pour recevoir la barre de liaison 4. Cela évite un éventuel basculement de la structure solaire 2 lors de son assemblage. Lors de l'assemblage de la structure solaire 2, les pieds d'ancrage 5a, 5b et 5c sont positionnés spatialement sur le gabarit de montage 20 en appui dans les mors 26 et 27, l'extrémité d'ancrage de chacun des pieds d'ancrage étant position au droit d'un sommet de la base polygonale 25. Dans le cas d'espèce, le pied d'ancrage 5c repose en appui dans le mors 26, alors que les pieds d'ancrage 5a et 5b reposent en appui dans les mors 27 de sorte à ce que leurs extrémités opposées aux extrémités d'ancrage soient en contact, comme illustré sur la figure 1 . De là, les deux pieds d'ancrage 5a et 5b sont fixés l'un à l'autre par agrafage 7 et/ou l'installation d'une plaque de liaison 8. Tout autre moyen de liaison idoine peut être utilisé à cet effet. Ensuite, l'extrémité de montage 3a est assemblée au niveau des extrémités en contact des pieds d'ancrage 5a et 5b. L'extrémité de montage 3b est assemblée sur l'extrémité opposée à l'extrémité d'ancrage du pied d'ancrage 5c. La barre de liaison 4 relie les deux extrémités de montage 3a et 3b. In order to assemble such a solar structure 2, a mounting template 20 is provided. This mounting template 20 has a tubular polygonal base 25 (here tubes of square section) mounted on feet 28 located at each vertex of the polygonal base. In the case illustrated in Figure 1, the polygonal base is a triangle. In general, the polygonal base has as many vertices as there are anchoring feet 5a, 5b, 5c of the solar structure 2. Each of the vertices receives an anchor foot end of the solar structure 2 to be assembled . The mounting jig has a middle bar 25 passing through the polygonal base 25. Perpendicularly to the polygonal base 25, two uprights 22 and 23 rise from the middle bar 25 at the free ends of which is fixed a reinforcement bar 21, here substantially parallel at the center bar 24. At each end of the reinforcing bar 21, jaws 26 and 27 are provided. These jaws 26 and 27 are used to maintain, for the assembly of the solar structure 2, the anchoring feet 5a, 5b and 5c. The jaws 26 and 27 are positioned so as to maintain a relative spatial position between the different anchoring feet of the solar structure 2 to be assembled. An additional jaw 28 is provided to receive the connecting bar 4. This avoids a possible tilting of the solar structure 2 during its assembly. During the assembly of the solar structure 2, the anchoring feet 5a, 5b and 5c are positioned spatially on the mounting jig 20 resting in the jaws 26 and 27, the anchoring end of each of the feet anchoring being positioned at the right of a top of the polygonal base 25. In the case in point, the anchoring foot 5c rests in support in the jaw 26, while the anchoring feet 5a and 5b rest in support in the jaws 27 so that their opposite ends to the anchoring ends are in contact, as shown in Figure 1. From here, the two anchoring feet 5a and 5b are fixed to each other by stapling 7 and / or the installation of a connecting plate 8. Any other suitable connection means can be used for this purpose . Next, the mounting end 3a is assembled at the contacting ends of the anchor legs 5a and 5b. The mounting end 3b is assembled on the opposite end to the anchoring end of the anchor foot 5c. The connecting bar 4 connects the two mounting ends 3a and 3b.
La structure solaire 2 est alors ainsi assemblée. Une ceinture de maintien et de manipulation 1 0 est positionnée autour des pieds d'ancrage 5a, 5b et 5c. Ici, la ceinture de maintien et de manipulation 10 est fixée au niveau de la moitié inférieure en hauteur des pieds d'ancrage au moyen d'axes traversant 1 1 a, 1 1 b et 1 1 c. En variante de réalisation, la ceinture de maintien et de manipulation est positionnée au niveau du tiers de ladite hauteur des pieds d'ancrage. Tout autre moyen de fixation peut être utilisé pour fixer ladite ceinture 1 0 à la structure solaire 2. En référence aux figures 2 et 3, nous allons maintenant décrire un procédé d'encastrement selon l'invention de la structure solaire 2 dans le sol. Le procédé d'encastrement selon l'invention de la structure solaire 2 comprend les étapes suivantes :  The solar structure 2 is then assembled. A holding and handling belt 10 is positioned around the anchor legs 5a, 5b and 5c. Here, the holding and handling belt 10 is fixed at the level of the lower half height of the anchoring feet by means of axes passing through 11a, 11b and 11c. In an alternative embodiment, the holding and handling belt is positioned at a third of said height of the anchoring feet. Any other fastening means may be used to fasten said belt 1 0 to the solar structure 2. With reference to Figures 2 and 3, we will now describe a method of embedding according to the invention of the solar structure 2 in the ground. The embedding method according to the invention of the solar structure 2 comprises the following steps:
- réalisation (étape 100) de deux trous T1 et T2 dans lesquels les extrémités d'ancrages des pieds d'ancrages 5a, 5b et 5c sont destinées à être encastrées. La réalisation de ces trous T1 , T2 est connue de l'état de la technique et ne sera pas plus détaillée. Il est prévu, afin d'améliorer l'encastrement des structures solaires 2, d'aménager un treillis soudé 40 placé sur des cales 41 au fond des trous T1 , T2.  - Realization (step 100) of two holes T1 and T2 in which the anchoring ends of the anchoring feet 5a, 5b and 5c are intended to be recessed. The realization of these holes T1, T2 is known from the state of the art and will not be more detailed. It is intended, in order to improve the embedding of solar structures 2, to develop a welded mesh 40 placed on shims 41 at the bottom of holes T1, T2.
- réalisation (étape 1 10) d'un ou plusieurs piquetage(s) pour le positionnement d'une côte d'implantation dans chaque trous T1 et T2, ainsi que le positionnement des extrémités d'ancrage de la structure solaire 2. Plus précisément, le but est de déterminer l'épaisseur d'une dalle 30 de béton à couler, d'une part, et, d'autre part, le positionnement de moyens de liaison 50 de la dite structure solaire 2.  - Realization (step 1 10) of one or more stakes (s) for the positioning of an implantation rib in each hole T1 and T2, and the positioning of the anchoring ends of the solar structure 2. More precisely , the aim is to determine the thickness of a concrete slab 30 to be cast, on the one hand, and, on the other hand, the positioning of connection means 50 of said solar structure 2.
- mise en place (étape 120) de moyens de liaisons 50 dans un voisinage de la position des extrémités d'ancrage de la structure solaire 2. Ces moyens de liaison 50 sont ici des fers à béton déformés de manière à comporter une boucle en U fixés fermement au treillis 30, un sommet de la boucle en U étant positionné au dessus de la côte d'implantation, - Establishment (step 120) of connection means 50 in a vicinity of the position of the anchoring ends of the structure solar 2. These connecting means 50 are here deformed reinforcing bars so as to comprise a U-shaped loop firmly fixed to the mesh 30, an apex of the U-shaped loop being positioned above the implantation rib,
coulage (étape 1 30) de la dalle de béton 30 dans chacun des trous T1 et T2 à la côte d'implantation.  casting (step 1 30) of the concrete slab 30 in each of the holes T1 and T2 at the implantation edge.
sur le gabarit de montage 20, assemblage (étape 140) de la structure solaire 2 comme décrit précédemment. Le gabarit est installé de préférence au voisinage des trous T1 et T2. une fois la(es) dalle(s) de béton sèche(s) (prise du béton), repérage (étape 150) de la position exacte des pieds d'ancrage de la structure solaire 2 sur la(es) dalle(s) de béton,  on the mounting template 20, assembly (step 140) of the solar structure 2 as previously described. The template is preferably installed in the vicinity of the holes T1 and T2. once the dry concrete slab (s) (setting the concrete), locating (step 150) the exact position of the anchoring feet of the solar structure 2 on the slab (s) of concrete,
déplacement (étape 1 60) de la structure de liaison depuis le gabarit de montage jusqu'au trous T1 et T2 et installation de ladite structure solaire 2 sur la(es) dalle(s) de béton, l'extrémité d'ancrage de chacun des pieds d'ancrage 5a, 5b et 5c de la structure solaire 2 venant en appui sur la(es) dalle(s) de béton au droit de sa position respective précédemment repérée, fixation (étape 170) des pieds d'ancrage aux moyens de liaison 50. cette fixation est réalisée à l'aide de fers à béton positionnés à travers les orifices traversant 6a, 6b et 6c et ensuite reliés fermement aux moyens de liaison, ici au niveau des sommets des boucle en U émergeant de la(es) dalle(s) de béton. La ceinture de maintien et de manipulation 1 0 est retirée de la structure solaire 2. encastrement (étape 180) de la structure solaire 2 en coulant une couche supplémentaire de béton 70. Un coffrage peut être réalisé autour de chaque pied d'ancrage afin de réduire la quantité de béton utilisé pour réalisée la couche supplémentaire 70. Une fois la couche supplémentaire de béton sèche (prise du béton), chaque trou T1 , T2 est rebouché avec la terre de remblai 80.  displacement (step 1 60) of the connection structure from the mounting template to the holes T1 and T2 and installation of said solar structure 2 on the concrete slab (s), the anchoring end of each anchoring feet 5a, 5b and 5c of the solar structure 2 resting on the concrete slab (s) in line with its respective previously identified position, fixing (step 170) of the anchoring feet to the means link 50. this fixing is carried out using concrete irons positioned through the through orifices 6a, 6b and 6c and then firmly connected to the connecting means, here at the vertices of the U-shaped loop emerging from the ) slab (s) of concrete. The holding and handling belt 1 0 is removed from the solar structure 2. embedding (step 180) of the solar structure 2 by casting an additional layer of concrete 70. A formwork can be made around each anchor foot to reduce the amount of concrete used to make the additional layer 70. Once the additional layer of concrete dry (setting the concrete), each hole T1, T2 is closed with the earth embankment 80.
En variante de réalisation, un béton fibré peut être utilisée pour le coulage afin d'améliorer l'encastrement et /ou la résistance de la(des) dalle(s) de béton 30. Dans ce dernier cas, le treillis 40 peut être omis. Avec un tel procédé, il est possible de contrôler le positionnement des structures solaires 2 (±25 mm) durant l'étape de coulage de la couche de béton permettant ainsi de ne pas fausser le contrôle de l'inclinaison des panneaux solaires installés sur lesdites structures solaires, notamment en garantissant le positionnement de la structure solaire. In an alternative embodiment, a fiber-reinforced concrete may be used for casting in order to improve the embedding and / or the resistance of the concrete slab (s). In the latter case, the lattice 40 may be omitted. . With such a method, it is possible to control the positioning of the solar structures 2 (± 25 mm) during the pouring step of the concrete layer thus making it possible not to distort the control of the inclination of the solar panels installed on said solar structures, in particular by guaranteeing the positioning of the solar structure.
D'autre part, lors d'un tel procédé d'encastrement selon l'invention, l'outillage est réutilisable de suite sans nécessité d'attendre la prise du béton. Ainsi, le gabarit de montage 20 et la ceinture de maintien et de manipulation 20 sont de suite réutilisés pour l'assemblage d'une nouvelle structure solaire. On the other hand, during such a method of embedding according to the invention, the tool is reusable immediately without the need to wait for the setting of the concrete. Thus, the mounting jig 20 and the holding and handling belt 20 are immediately reused for assembling a new solar structure.
