Description

Storage building such as chai

The invention relates to a storage building, including a cellar, containing a vat room composed of a plurality of storage tanks 5 resting on foundation elements. In the usual way, the traditional cellars consist of industrial buildings in which generally prefabricated storage tanks are distributed, for example aligned in bays separated by aisles. One of the drawbacks of such a conventional design lies in the fact that it leads to the construction of buildings with large dead volumes resulting in significant additional construction costs (storage volume ratio / total building low volume, significant lengths of the pipes and electrical wiring ...), and maintenance and upkeep. The present invention aims to overcome this drawback and its main purpose is to provide a storage building whose construction cost and the ratio of useful volume to total volume are optimized. For this purpose, the invention relates to a storage building, in particular a cellar, containing a vat room resting on foundation elements 20 and composed of a plurality of storage tanks each comprising an upper wall, a lower wall and a peripheral wall, said building being characterized, according to the invention, in that it comprises storage tanks, called peripheral tanks, having, in plan view, a generally convex trapezoidal section delimited by two at least substantially parallel front walls connected by two convergent side walls, said peripheral tanks being: - contiguous by their side walls so as to form an annular structure, said external, having an outer wall constituted by one of the front walls, said outer wall, peripheral tanks, and a wall interior, constituted by the other end wall, said internal wall, peripheral tanks, delimits an interior space for access to said peripheral tanks, said external annular structure having at least one communication passage with the interior space, 2944043 -2

- Maintained contiguous by means of connecting elements providing mechanical locking of all the peripheral vessels forming the outer annular structure. According to the principle of the invention, the peripheral storage tanks thus constitute, not only the vat room installed in the building, but also the general superstructure of this building, so that the production costs are reduced optimally. In addition, the annular shape adopted to achieve the building provides a very strong superstructure from basic elements, namely the storage tanks, light structure. With a view to the construction of a building, such storage tanks can in particular be prefabricated to dimensions allowing their road transport. It should be noted, moreover, the dismountability of the superstructure of the building made, for example in view of its transfer. This annular shape, combined with the use of storage tanks to carry out the infrastructure, also leads to obtaining a useful storage volume / total building volume ratio optimized. This annular shape also facilitates access to the storage tanks, both for the connection of different cabling and pipes, 20 than during filling and emptying operations of these storage tanks. According to an advantageous embodiment intended to optimize the modular concept of the invention, the peripheral tanks have, seen in plan, a section of generally isosceles trapezoidal shape. Furthermore, the connecting elements intended to ensure the mechanical rigidity of the building advantageously comprise at least one continuous locking belt relative to one of the front walls of the peripheral tanks, advantageously comprising: in at least one mechanical locking belt peripheral vessels forming a strapping extending in contact with the outer front walls of said peripheral tanks. and / or in at least one mechanical locking belt of the peripheral tanks, integral with the inner end walls of said peripheral tanks. 2944043 -3

Furthermore, in order to access the interior space of the building, and advantageously according to the invention, at least one of the peripheral tanks has a height less than that of the other peripheral tanks, said peripheral tank being positioned so that its bottom wall 5 is raised relative to the lower walls of the juxtaposed peripheral tanks, in order to delimit, with the adjacent side walls of said juxtaposed peripheral tanks, a gantry forming a communication passage with the interior space of the outer annular structure.

According to another advantageous characteristic of the invention and with a view to closing the building, the latter comprises a roof structure provided with supports adapted to bear on the upper walls of the peripheral tanks. In addition, the roof structure is then advantageously adapted to form a central blanking cover of the internal space of the outer annular structure, the peripheral tanks having an inclined upper wall adapted to form, concentrically around the central cover, a roof surface complementary to said central cover.

Moreover, particularly with a view to regulating the temperature inside the storage tanks, at least one of the walls of the peripheral tanks advantageously consists of a wall incorporating fluid circulation ducts. Such conduits are, in addition, stiffening elements of the storage tanks.

Regarding the increase of this stiffening, another advantageous solution consists in integrating in the peripheral tanks at least one spacer extending between the side walls of the latter. With a view to increasing the storage capacity, the building according to the invention may advantageously comprise a storage tank, called a central tank, disposed in the center of the interior space of the outer annular structure, so as to define a circulation lane. ring-shaped with the peripheral tanks. By the way, with a view to accessing the upper part of the 2944043 -4

internal volume of the storage tanks, each peripheral tank comprises at least one filling or visiting orifice formed in the upper wall and / or in the inner end wall of said peripheral tank, and the building advantageously comprises a so-called central staircase arranged in the space 5 inside the outer annular structure, serving, for each filling or visiting orifice, a platform access to said orifice. Such a staircase can advantageously be secured to the inner end walls of the peripheral tanks. As advantageous alternative embodiments, this central staircase may also consist of a spiral staircase: - carried by a central mast, each platform being carried by integral profiles of the inner end walls of the peripheral tanks and by said central mast, - housed inside a central shaft disposed in the inner space 15 of the outer annular structure, each platform being carried by integral sections respectively of the inner end walls of the peripheral tanks and the peripheral wall of the central shaft, - wrapping around the central tank, each platform being carried by integral sections respectively inner end walls 20 of the peripheral tanks and the peripheral wall of the central tank. In addition, the support of this spiral staircase, central mast, central shaft, or central vessel, advantageously has a height adapted to support the central portion of the roof structure. Regarding the internal volume of the storage tanks, the latter 25 may, in particular, either form a single tank, or be internally divided into two superimposed compartments, said upper and lower, separated by a transverse wall. In this second case, furthermore, the upper compartment may advantageously consist of a storage tank, and the lower compartment form a storage area communicating with the interior space of the outer annular structure through an opening in the internal front wall of the peripheral tank. Alternatively, the two superposed compartments may 2944043 -5

also advantageously consist of separate storage tanks. With regard to the production of the peripheral tanks, the latter may advantageously consist of metal tanks, made of a material such as stainless steel, and be carried by foundation elements consisting of a foundation block in the form of an annular ring. In this case, in addition, the lower wall of the peripheral tanks and the upper face of the foundation mass advantageously have a conjugate inclination adapted to define a slope converging towards the center of the internal space of the outer annular structure. The peripheral tanks may also be made of a material such as concrete, and each of said peripheral tanks may then be constituted by the superposition of two separate tanks, said upper and lower, each constituting an independent storage volume. In this case, moreover, in order to release a large circulation width at ground level, the upper tank advantageously has a depth greater than that of the lower tank, so as to extend partially in overflow relative to the plumb with the inner front wall of said lower vessel. On the basis of the concept of the invention which consists in producing an external annular structure, various solutions may be provided for the interior space of this annular structure. Thus, according to an advantageous embodiment, the building 25 may comprise at least a second annular structure, called internal, consisting of contiguous storage tanks having, in plan view, a convex generally trapezoidal shaped section, said internal annular structure s' extending concentrically within the outer annular structure and being separated therefrom by an annular circulation path.
