  • - des murs munis de portes étanches et installés dans le parking pour diviser chaque niveau en salles dont la capacité d'occupation est à l'échelle humaine,
  • - un puits creusé dans le terrain à l'extérieur de l'ossature du parking et contenant une colonne technique préfabriquée, monolithique et compartimentée, noyée dans une enveloppe en béton qui est coulée sur place en réservant, à chaque niveau que cette colonne dessert en regard d'au moins une salle, des passages d'accès traversant ladite ossature, la colonne comprenant notamment un escalier hélicoïdal avec paliers devant les passages d'accès, une gaine d'admission d'air frais et une gaine d'évacuation d'air usé
  • - et au moins une cabine technique intérieure par niveau, dimensionnée au gabarit des rampes d'accès existantes du parking et de préférence limitée à la surface au sol d'un emplacement d'automobile, cette cabine comprenant un local machinerie et un local de ventilation branchés sur les deux gaines précitées, ainsi qu'un sas reliant la ou les salles à l'escalier.
In accordance with the invention, the installation comprises:
  • - walls fitted with watertight doors and installed in the car park to divide each level into rooms whose occupancy capacity is on a human scale,
  • - a well dug in the ground outside the framework of the car park and containing a prefabricated, monolithic and compartmentalized technical column, embedded in a concrete envelope which is poured on site reserving, at each level that this column serves in look of at least one room, access passages passing through said framework, the column comprising in particular a helical staircase with bearings in front of the access passages, a fresh air intake duct and an exhaust duct waste air
  • - And at least one interior technical cabin per level, sized to the size of the existing access ramps to the car park and preferably limited to the floor area of an automobile location, this cabin comprising a machine room and a ventilation room connected to the two aforementioned ducts, as well as an airlock connecting the room or rooms to the staircase.

En outre, suivant une forme de réalisation préférentielle, la gaine d'admission d'airfrais de la colonne coopère avec un empilage de locaux de préfiltrage qui sont branchés chacun sur les filtres du local de ventilation de la cabine technique de même niveau; la gaine d'admission d'airfrais débouche à l'extérieur par une bouche située à proximité de la trappe de l'escalier, tandis que la gaine d'évacuation présente, à sa partie supérieure, une déviation par laquelle elle débouche à l'extérieur par une bouche, ainsi disposée à distance de la bouche d'admission; l'installation comporte deux cabines techniques intérieures raccordables l'une à l'autre, la première comportant le sas et une chambre machinerie dans laquelle se trouvent notamment un réservoir à combustible de grande capacité et un groupe électrogène, tandis que le deuxième comporte un compartiment à filtres et à ventilateurs ainsi qu'une chambre de commande, le sas présentant, d'une part, une porte s'ouvrant sur la ou les salles et, d'autre part, deux portes s'ouvrant respectivement sur l'escalier et sur la chambre machinerie.In addition, according to a preferred embodiment, the fresh air intake duct of the column cooperates with a stack of prefiltering rooms which are each connected to the filters of the ventilation room of the technical cabin of the same level; the fresh air intake duct opens to the outside through a mouth located near the staircase hatch, while the evacuation duct has a deviation at its upper part through which it opens to the outside by a mouth, thus disposed at a distance from the intake mouth; the installation comprises two interior technical cabins that can be connected to each other, the first comprising the airlock and a machinery chamber in which there is in particular a large-capacity fuel tank and a generator, while the second comprises a compartment with filters and fans as well as a control chamber, the airlock having, on the one hand, a door opening onto the room or rooms and, on the other hand, two doors opening respectively onto the staircase and on the machinery room.

Avantageusement, les passages d'accès entre la colonne et la cabine de chaque niveau sont constitués par des éléments de couloir et de conduites traversant des percements de l'ossature bétonnée ou maçonnée du parking et soudés, à une extrémité, sur la cage métallique d'escalier et les deux gaines métalliques, respectivement, à l'autre extrémité, sur la paroi métallique de la cabine, le béton étant alors coulé entre ladite colonne et la paroi du puits et un joint, notamment en résine, étant ensuite injecté à travers au moins un trou des éléments précités entre ceux-ci et la paroi des percements.Advantageously, the access passages between the column and the cabin of each level are formed by corridor elements and conduits passing through holes in the concrete or masonry framework of the car park and welded, at one end, to the metal cage d staircase and the two metal sheaths, respectively, at the other end, on the metal wall of the cabin, the concrete then being poured between said column and the wall of the well and a joint, in particular made of resin, then being injected through at least one hole of the aforementioned elements between them and the wall of the openings.

Divers autres caractéristiques et avantages de l'invention ressortent d'ailleurs de la description détaillée qui suit.Various other characteristics and advantages of the invention will also emerge from the detailed description which follows.

Une forme de réalisation de l'objet de l'invention est représentée, à titre d'exemple non limitatif, sur le dessin annexé.An embodiment of the object of the invention is shown, by way of nonlimiting example, in the accompanying drawing.

Sur ce dessin:

  • la fig. 3 est une coupe-élévation partielle prise suivant la ligne III-III de la fig. 2,
  • la fig. 4 est une autre coupe-élévation partielle prise suivant la ligne IV-IV de la fig. 2.
On this drawing:
  • fig. 1 is a schematic plan view showing a parking level equipped with the installation according to the invention,
  • fig. 2 is an enlarged plan view illustrating a well of the installation and the cooperating cabins for a parking level,
  • fig. 3 is a partial sectional elevation taken along line III-III of FIG. 2,
  • fig. 4 is another partial sectional elevation taken along line IV-IV of FIG. 2.

Ainsi que cela ressort de la fig.1, chaque niveau de parking souterrain 1 comporte des murs 2 et 3 séparant des salles 4.1, 4.2, 4.3, 4.4 ... dont la capacité d'occupation est à l'échelle humaine. Ces salles sont desservies en temps normal, à travers des ouvertures 5.1, 5.2, 5.3, 5.4..., par les allées 6 d'un réseau de communication auquel il est possible d'accéder, pour les véhicules, par des rampes inclinées et, pour les piétons, par des escaliers internes, ces rampes et escaliers n'étant pas représentés sur le dessin.As shown in fig.1, each level of underground parking 1 has walls 2 and 3 separating rooms 4.1, 4.2, 4.3, 4.4 ... whose occupancy is on a human scale. These rooms are normally served, through openings 5.1, 5.2, 5.3, 5.4 ..., by aisles 6 of a communication network to which it is possible to access, for vehicles, by inclined ramps and , for pedestrians, by internal stairs, these ramps and stairs are not shown in the drawing.

Pour transformer ces salles en abris pour la protection N B C, il faut d'abord pouvoir les isoler avec étanchéité parfaite les unes des autres; à cet effet, des portes à fermeture étanche 7.1, 7.2, 7.3, 7.4 ... et 8.1, 8.2, 8.3, 8.4 ... sont prévues pour obturer les ouvertures 5 précitées, Par ailleurs, il faut pouvoir, d'une part, permettre à la population de se rendre dans chaque abri et d'en sortir vers l'extérieur en respectant les consignes de sécurité N B C, d'autre part, changer l'air vicié de l'abri considéré et le remplacer par de l'air frais convenablement filtré. A cet effet, des puits 9.1, 9.2, 9.3, 9.4 ... sont creusés pour desservir le même emplacement des niveaux superposés des salles correspondantes 4.1, 4.2, 4.3, 4.4 ... et des cabines 10.1, 10.2, 10.3, 10.4 ... sont implantées à cet emplacement desdits niveaux pour coopérer avec lesdits puits.To transform these rooms into shelters for protection N B C, it must first be able to isolate them with perfect sealing from each other; for this purpose, watertight closing doors 7.1, 7.2, 7.3, 7.4 ... and 8.1, 8.2, 8.3, 8.4 ... are provided to close the aforementioned openings 5. Furthermore, it must be possible, on the one hand , allow the population to go to each shelter and exit to the outside while respecting the NBC safety instructions, on the other hand, change the stale air of the shelter considered and replace it with properly filtered fresh air. For this purpose, wells 9.1, 9.2, 9.3, 9.4 ... are dug to serve the same location of the superimposed levels of the corresponding rooms 4.1, 4.2, 4.3, 4.4 ... and the booths 10.1, 10.2, 10.3, 10.4. .. are located at this location of said levels to cooperate with said wells.

Comme le montrent les figures 2 à 4, chaque puits 9 est creusé à l'extérieur de l'ossature 11 du parking, généralement en béton armé, depuis la surface du sol jusqu'au niveau le plus bas. Ce puits 9 contient une colonne technique 12, préfabriquée en tolerie métallique, en béton armé ou autre; la colonne est monolithique et compartimentée; elle comprend un escalier hélicoïdal 13, une gaine d'admission d'air frais 14 et une gaine d'évacuation d'air usé 15. En regard de chaque niveau, l'escalier 13 présente un palier 16 sur lequel débouche, d'une part, un élément de couloir 17 traversant un percement 18 de l'ossature 11 et solidaire de la cage de cet escalier, d'autre part, une porte de visite 19 s'ouvrant sur un local de préfiltrage 20 interposé entre la gaine d'admission d'air frais 14 et un élément de conduite 21 traversant un percement 22 des l'ossature 11. De même que l'élément de conduite 21 est solidaire de la paroi du local 20 communiquant avec la gaine d'admission 14, un autre élément de conduite 23 est solidaire de la gaine d'évacuation 15 et traverse un percement 24 de l'ossature 11.As shown in FIGS. 2 to 4, each well 9 is dug outside the framework 11 of the car park, generally made of reinforced concrete, from the ground surface to the lowest level. This well 9 contains a technical column 12, prefabricated in metal sheet metal, reinforced concrete or other; the column is monolithic and compartmentalized; it includes a helical staircase 13, a fresh air intake duct 14 and a spent air discharge duct 15. Opposite each level, the staircase 13 has a landing 16 onto which opens out on the one hand, a corridor element 17 passing through a hole 18 in the frame 11 and secured to the cage of this staircase, on the other hand, an inspection door 19 opening onto a pre-filtration room 20 interposed between the sheath fresh air intake 14 and a pipe element 21 passing through a hole 22 in the framework 11. Just as the pipe element 21 is fixed to the wall of the room 20 communicating with the intake duct 14, another pipe element 23 is fixed to of the evacuation sheath 15 and passes through a hole 24 in the frame 11.

Au niveau du sol (fig. 4), la colonne 12 est entourée par une clôture 25 munie d'une porte 26. Une trappe 27 obture normalement l'escalier dans le but de n'être ouverte qu'en cas de service; de toute façon, la forme hélicoïdale de l'escalier interdit aux poussières radioactives qui pourraient franchir cette trappe de parvenir aux niveaux inférieurs. De plus, la bouche d'admission 28 de la gaine 14 est munie d'une grille 29 située dans l'enceinte définie par la clôture 25; par contre, la partie supérieure de la gaine 15 est solidaire d'une déviation 30 s'étendant latéralement dans le sol et communiquant avec l'extérieur par une bouche d'évacuation 31 pourvue d'une grille 32 située à distance suffisante de la précédente pour éviter la pollution.At ground level (fig. 4), the column 12 is surrounded by a fence 25 provided with a door 26. A hatch 27 normally closes the staircase in order to be opened only in the event of service; in any case, the helical shape of the staircase prevents radioactive dust which could cross this hatch from reaching the lower levels. In addition, the inlet mouth 28 of the sheath 14 is provided with a grid 29 located in the enclosure defined by the fence 25; on the other hand, the upper part of the sheath 15 is integral with a deflection 30 extending laterally into the ground and communicating with the outside by a discharge mouth 31 provided with a grid 32 located at a sufficient distance from the previous one to avoid pollution.

Lorsque la colonne 12 est en place et raccordée aux cabines intérieures 10, de la manière décrite dans ce qui suit, du béton est coulé autour pour remplir le puits et constituer une enveloppe ou coque protectrice 33.When the column 12 is in place and connected to the interior cabins 10, as described below, concrete is poured around it to fill the well and form a protective shell or shell 33.

Ainsi que cela apparaît clairement sur les figures 2 et 3, l'installation comporte à chaque niveau, sur un emplacement d'automobile, au moins une cabine technique intérieure 10; en réalité, dans l'exemple représenté, deux cabines 34 et 35, juxtaposables et raccordables entre elles, sont prévues pour pouvoir être amenées chacune en entier par le réseau de communication du parking, c'est-à-dire en empruntant sans difficultés les rampes inclinées, les allées 6 et les ouvertures 5. Ces cabines 34 et 35 sont de préférence métalliques, mais elles peuvent aussi être réalisées en tout autre matériau du moment que les conditions de résistance et d'étanchéité sont respectées.As is clearly seen in FIGS. 2 and 3, the installation comprises at each level, on a car site, at least one interior technical cabin 10; in reality, in the example shown, two cabs 34 and 35, juxtaposed and connectable to each other, are provided to be able to be brought each entirely by the parking lot communication network, that is to say without difficulty using the inclined ramps, aisles 6 and openings 5. These cabs 34 and 35 are preferably metallic, but they can also be made of any other material as long as the conditions of resistance and sealing are respected.

La cabine 34 comporte un sas 36 et une chambre machinerie 37 dans laquelle sont installés un réservoir à combustible de grande capacité 38 et un groupe électrogène 39 de puissance suffisante pour subvenir aux besoins de la salle 4 correspondante. Le sas 36 présente une porte 40 le faisant communiquer avec ladite salle et deux autres portes 41 et 42 livrant accès respectivement à la chambre 37 et à l'élément de couloir 17 desservant l'escalier. Les portes sont à fermeture étanche et au moins la porte 42 est munie d'une soupape de surpression permettant de mettre le sas à la pression atmosphérique extérieure, aloirs qu'il se trouve, comme la salle considérée, en légère surpression dès que ladite porte 42 est refermée.The cabin 34 includes an airlock 36 and a machinery chamber 37 in which are installed a large capacity fuel tank 38 and a generator 39 of sufficient power to meet the needs of the corresponding room 4. The airlock 36 has a door 40 making it communicate with said room and two other doors 41 and 42 providing access respectively to the bedroom 37 and to the corridor element 17 serving the staircase. The doors are watertight and at least door 42 is provided with a pressure relief valve allowing the airlock to be brought to outside atmospheric pressure, aloirs that it is, like the room considered, under slight overpressure as soon as said door 42 is closed.

La cabine 35 comprend un compartiment 43 dans lequel sont installés en parallèle des filtres 44 et un appareil de ventilation 45 alimenté, à travers ceux-ci, par une canalisation 46 branchée sur les préfiltres de la chambre 20 raccordés à la gaine d'admission 14; l'appareil de ventilation 45 débite l'air frais dans la salle 4 considerée dont l'air vicié s'échappe à travers des soupapes de surpression vers une canalisation, non représentée, raccordée à la gaine d'évacuation 15. La cabine 35 comprend également une chambre de commande 47 dont une porte 48 s'ouvre sur la salle 4 et qui livre accès aux filtres 44, à l'appareil de ventilation 46 et à leurs équipements, contenus dans le compartiment 43.The cabin 35 comprises a compartment 43 in which filters 44 are installed in parallel and a ventilation device 45 supplied, through these, by a pipe 46 connected to the prefilters of the chamber 20 connected to the intake duct 14 ; the ventilation device 45 delivers the fresh air into the room 4 considered from which the stale air escapes through pressure relief valves to a pipe, not shown, connected to the exhaust duct 15. The cabin 35 comprises also a control chamber 47, a door 48 of which opens onto room 4 and which provides access to the filters 44, to the ventilation device 46 and to their equipment, contained in the compartment 43.

Les cabines 34et 35 de chaque niveau sont raccordées à la colonne 12 au moyen des éléments 17, 21 et 23. Ainsi, après installation, l'élément de couloir 17 est soudé à ses extrémités sur la cage d'escalier et sur le sas 36, l'élément de conduite 21 sur la paroi du local de préfiltrage 20 et la canalisation 46, l'élément de conduite 23 sur la gaine d'évacuation 15 et la canalisation d'échappement ou la paroi de la chambre 37. La solidarisation étanche étant ainsi assurée entre la colonne extérieure 12 et les cabines intérieures 34, 35, le béton est coulé entre la paroi du puits 9 et ladite colonne pour constituer l'enveloppe protectrice 33. Puis, des trous percés dans les éléments 17, 21 et 23 pour injecter un joint, en résine par exemple, entre ces éléments et la paroi des percements 18, 22 et 24.The cabins 34 and 35 on each level are connected to the column 12 by means of the elements 17, 21 and 23. Thus, after installation, the corridor element 17 is welded at its ends to the stairwell and to the airlock 36 , the pipe element 21 on the wall of the prefilter room 20 and the pipe 46, the pipe element 23 on the evacuation sheath 15 and the exhaust pipe or the wall of the chamber 37. The tight connection thus being ensured between the outer column 12 and the inner cabins 34, 35, the concrete is poured between the wall of the well 9 and the said column to form the protective envelope 33. Then, holes drilled in the elements 17, 21 and 23 to inject a seal, in resin for example, between these elements and the wall of the holes 18, 22 and 24.
