Definitions
- the present invention relates to the process for constructing enclosures or swimming pools used in the nuclear industry and to the swimming pool obtained according to this process in accordance with the preambles of claims 1 and 4.
- swimming pools of this kind are formed by a massive concrete polygonal profile whose vertical wall facing inward is covered by a metal coating, usually consisting of an assembly of stainless steel sheets.
- This coating must obviously have a perfect seal and homogeneity, so that it has proved essential to carry out the radiographic verification of the welds for joining the sheets, this verification having to take place both immediately after construction of the pool and periodically during the use thereof.
- French patent application No. 2 383 289 proposed to carry out the assembly welds of the sheets of the coating at the level of hollow metal profiles arranged vertically so that their face turned towards the he interior of the swimming pool is at the level of the concrete wall intended to form a support for the aforementioned coating.
- the support surface is thus preserved in its entirety and the interior space delimited by each profile can receive an X-ray film engaged by the upper end of the profile considered, which film is capable of cooperating with a source or probe lowered into the pool. .
- the present invention aims to remedy the aforementioned drawbacks of the prior art and to allow the simple and economical construction of a swimming pool for the nuclear industry of the aforementioned type, that is to say in which the internal metallic coating is applied against a bearing face interrupted by vertical metal sections provided hollow.
- the invention essentially consists, according to the characterizing parts of claims 1 and 4, of constituting the bearing face by superimposition on edge of rigid plates of cement or fiber cement with smooth walls, the superimposed plates being retained by projecting lateral fins provided facing each other on the vertical sections so as to behave in the manner of a lost formwork for pouring the concrete mass intended for filling the empty space formed between the solid and the superposition cited above.
- the reference 1 designates the vertical wall of the concrete block, the face la of this wall being set back with respect to the dimension provided for the swimming pool, by a distance which can vary to a large extent and which in this case will assume to be of the order of 60 to 100 mm.
- a distance which can vary to a large extent and which in this case will assume to be of the order of 60 to 100 mm.
- a pair of irons 2 Across the side there are, in the usual way, referred to regular horizontal spacings, superimposed pairs 2 of vertical angle irons, fixed in place in any suitable manner, for example using sealed bolts or the like; each pair of irons 2 embraces a vertical profile 3 with a U-shaped cross section which opens towards the interior of the pool, that is to say opposite to the face 1 a.
- Each of the sections 3, assembled to the irons 2 by welding or otherwise, is closed by a vertical strip 4 made of stainless steel to form a hollow section.
- Such an assembly corresponds to the conventional construction in terms of swimming pools for the nuclear industry, for example according to French patent application No. 2 383 289 and therefore does not require a more detailed description.
- each slat 4 is established at a width slightly greater than that of the profile 3 which supports it, so as to thus determine two fins which project laterally with respect to said profile 3.
- the protruding fins, turned in the direction of one another, two contiguous slats 4 constitute a kind of clean vertical slide ensuring the retention of a series of superimposed plates 5, made of cement or, advantageously, of fiber cement.
- the vertical edges of these plates 5 are milled at 5a over a width equal to that of the fins projecting from the slats 4, so that the outer wall of said plates is at the same level as the free face of the aforementioned slats.
- these plates 5 constitute a formwork which determines, with the face 1a of the block 1, a free space referenced 9 in FIG. 2.
- the space 9 then has a relatively reduced height and it is easy under these conditions to operate the lining by introducing an appropriate amount of mortar or concrete, for example using a simple pump. After the mass thus injected has hardened, the operation is repeated, in the sense that a suitable number of plates 5 are again superimposed and that the new space 9 thus formed is filled with concrete.
- the reinforcement ladder 6 is dismantled after sectioning the fasteners 8.
- the plates 5 obviously remain incorporated in the assembly obtained, comprising it in the manner of a lost formwork.
- the value of this formwork can be considered negligible, especially if we take into account that its surface is presented in an absolutely smooth manner, without requiring any finishing work.
- the stainless steel sheets shown diagrammatically at 10 in FIG. 2, can bear against the plates 5 without any risk of deformation or of punching, in the same way, so that at the level of the vertical slats 4 associated with the profiles 3.
