Definitions

• the present invention relates to a device for protection against the flow of fluids.
• It relates more particularly to a device composed of several modules, intended to be used to protect buildings or premises against the consequences resulting from phenomena such as floods or mudslides.
• bags of non-coagulable powder materials such as sand, are piled up around the areas to be protected.
• Document FR 2 488 300 thus discloses an individual assemblable structure, provided for making cofferdams.
• the structure described in this document comprises a closed metal hollow profile, the periphery of which is arranged to define a succession of projections and recesses allowing the fitting of similar profiles to form a wall.
• the device is not modular since once mounted, it must be placed in a sealing frame, so that it is not possible to adapt the device either by adding elements or by removing or moving it or adjusting its position, without at least partial disassembly of the assembly.
• European patent application 0 163 292 describes a device for stopping flood waters which is composed of longitudinal elements fitted one on top of the other, each element comprising in its lower part a groove designed to engage a rail formed on the part top of the element below. According to the method described, the profiles are superimposed and secured by means of a part forming a lag screw.
• This device can only be validly used on a flat and regular surface. Indeed, the basic element is placed on a plate anchored in the ground, and is not held in place by means of a specific element. The device has no means of compensating for any irregularities in the implantation surface.
• this device is not modular, insofar as it is necessary due to the presence of permanently installed lag bolts and an anchoring in the ground, to predefine the dimensions of the panel before its installation without subsequent possibility of adaptation or modification, except for completely dismantling the panel and resuming its dimensions.
• Document FR 2 601 054 describes a dam for a watercourse which is composed of a frame and a movable vertical door composed of hollow metal profiles having on each side a succession of shoulders and hollows.
• This dam which is designed to be used on a watercourse, is composed of a frame formed by a threshold associated with vertical uprights, this frame being sealed on the ground and on the sides. Sealing at the base of the dam is achieved by insertion before the installation of a seal in a groove located at the base of the first section forming the vertical door.
• Document DE 196 49868 also describes a protective panel made up of elements fitted one on top of the other and engaged in a profile forming a support frame.
• This frame consists of a large piece in the shape of a "U" whose two vertical branches have a recess provided for receiving superimposed elements making up the panel.
• the lateral uprights which hold the profiles forming the panel in place are neither independent nor dissociated from the threshold part.
• This solution also does not offer perfect modularity of the panel, because it will be necessary once the phenomenon of fluid flow is complete to disassemble and completely remove the structure if one wishes to be able to clear the opening which had been protected.
• the present invention proposes to remedy the drawbacks mentioned above by providing a modular device for protection against the flow of fluids, characterized in that it comprises a protective panel produced by means of different planar surface elements having no roughness or relief, and designed to fit into each other.
• the device comprises a threshold seal which is compressed vertically, and side seals which are compressed horizontally, so as to ensure perfect sealing of the assembly.
• FIG. 1 is a section in side section of a device according to the present invention
• FIG. 2 is a top view of a protective panel
• FIG. 3 is a top view of an alternative embodiment of a protective panel
• Figure 4 is a front view of one end of the device.
• Figure 1 shows the general principle of assembly of the device according to the invention.
• the device according to the invention comprises a panel (1) composed of different elements (2) designed to fit into each other and held in position by two lateral slides (3), positioned on the sides of the area or of the structure to be protected.
• the panel (1) is made from identical longitudinal elements (2) which are associated with each other to form a set of determined size.
• Each element (2) has on its lower part a longitudinal U-shaped groove (12) and on its upper part a shoulder (22) of corresponding dimension, also covering the entire length.
• the element (2) located at the base of the panel will receive over its entire length a compressible block (5), which will be in direct contact with the ground.
• the dimensions and thickness of the block (5) are defined so as to compensate for any irregularities in the ground or the support.
• the vertical compression is carried out under the sole effect of the pressure exerted by the different elements (2) superimposed to constitute the protective panel (1).
• This characteristic is particularly important. Thanks to the presence at the base of the panel of a compressible block forming a joint and in direct contact with the ground, without the interposition of threshold elements or a rigid base, the device can very easily adapt to its own configuration at each site to be equipped. Irregularities or deformations of the ground will be absorbed and compensated for solely by the differentiated compression exerted on the compressible block as a result of the superposition of the various profiles forming the panel.
• the device also comprises two identical side rails (3) which are arranged one opposite the other on either side of the opening to be closed.
• a protection device it suffices to have a panel (1) formed by assembling several elements (2) as described above, and to insert the assembly by sliding inside the two side rails (3) which will have been fixed beforehand on the uprights of the opening to be closed.
• the side rails (3) are composed of a U-shaped profile (13), the bottom part of which faces outward in the plane perpendicular to that of the opening to be closed, so as to form a stop for the panel. (1) which will be inserted there by sliding.
• the U-shaped profile (13) has in section a dimension greater than the thickness of the elements (2) of the panel (1), which therefore leaves a space between the lateral wings of said profile and the walls of said elements.
• a vertical seal carrier rail (6) designed to receive an engaged seal (16) is mounted on the rear wing of the profile (13), to ensure the seal between the end of the rear wall of the panel (1) and the amount of the structure to be protected.
• the seal is made at the front of the device, that is to say between the front wall of the panel (1) and the corresponding wing of the profile (13) , by interposing a joint of bodywork type (7), that is to say having a double tube, one of which is open.
• the open tube of the seal (7) is engaged by simple clipping on the end of the front wing of the profile (13), and its free part formed by the closed tube fills in the rear the residual space between the front wing of the profile and the front wall of the panel (1), thereby ensuring both the maintenance and sealing of the assembly.
• the compression may be carried out by any suitable means allowing the panel (1) to be pressed against the slide (3) by compressing the side seals (7) or (16) according to the variant used.
• one or more slide-type clasps (8) will be used, arranged at each lateral end of the panel.
• the lateral slides (3) can be arranged inside the frame of the opening to be closed.
• each element (2) comprises at least one handle (10) extending over at least one of its sides, in order to allow the panel (1) to be easily moved or the elements which compose it to be separated, the maximum weight of each element being 25 kg. It is thus possible to produce panels which will ensure balanced compression on three sides, thus guaranteeing a perfect seal.
• the number of elements used, as well as their thickness or width dimension may vary depending on the water heights or the dimensional characteristics of the openings to be protected.
• the main advantage of the device according to the invention is that it limits the right-of-way works to the strict minimum, and therefore does not impose any structural modification, while maintaining the possibility of installation and subsequent disassembly at both simple and fast.
• the claimed device is not limited to the embodiment described above, which may be subject to any modification obvious to those skilled in the art without departing from the scope of the invention.
• both the dimensions and the materials used can be modified without this jeopardizing the essential characteristics of the device according to the invention.
