Description

DESCRIPTION

Watertight roller shutter and flood protection procedure

Technical sector

The present invention is in the general field of flood and flood protection of buildings.

It refers in particular to a set of protection against floods that makes it possible to protect houses, or other constructions made, from sudden rises in water, whose heights reached, at the time of its construction, were not indicated or even conceivable.

State of the art

The new risks of flooding in building land seem to be increasing, hence the protection set proposed below, designed mainly for private homes, shops, warehouses, private garages at street level, or underground, or underground public car parks.

This set, of conventional implementation, constitutes a watertight barrier, at a minimum height of one (1) meter for:

- allow its automatic start-up, easy, fast if necessary, without human intervention,

- comply with the regulations and standards in force in the corresponding countries,

- take into account the obligations that are sometimes imposed in insurance contracts that define the possible heights of the protections (cofferdams or equivalent) installed by the owners of the premises to protect themselves from possible floods,

- when regulations, decrees or laws leave owners free, the height of the watertight barrier can be increased without risk, in particular for underground garage descents.

This new barrier that blocks water in the event of a flood is permanently installed, connected and easy to build.

In order to take into account the global aesthetics of the barrier, the whole of the mechanism necessary for its operation is integrated in a closed box, which itself forms part, if desired, of an adapted window.

- Place above an entrance door, when it comes to a home, or an adapted support when it comes to a private or public garage descent.

This watertight barrier makes it possible to protect homes thus equipped to the maximum against floods, floods whose consequences are always economically heavy, morally difficult to live with, especially when they become repetitive.

technological background

The results of research carried out to find the available operational solutions for flood protection in the indicated niche, clearly show that there are a large number of possibilities offered for industry, seaside locations, storage locations, housing developments. ... etc., but there are few solutions for housing, its underground garages, houses near rivers.

For homes, private houses, underground garages, the proposed solutions range from sandbags placed one on top of the other, wooden cofferdams or other components that must be placed manually, when the risk of flooding becomes real. There are some more industrial proposals, all apparently manual, non-automatic, non-connected, such as the proposal disclosed in document DE102016009648 A1.

Except for the solution proposed in document EP1028219 A2, there are no permanent systems, which automatically start up when necessary, except for action controlled by the owner of the premises or by an automatic signal emitted nearby. In the latter case, reference may advantageously be made to patent application FR3039584 A1 in the name of one of the present inventors.

Therefore, there is a pressing need for a watertight flood protection barrier, the original design of which enables the drawbacks of the prior art discussed above to be overcome.

Object of the invention

The present invention refers to a flood protection assembly to protect a building, of simple design and mode of operation, which responds to the aforementioned drawbacks.

Another object of the present invention is a protection set of this type that comprises, for each opening of a building, a protection device, and that guarantees an automated deployment of the set of these protection devices when the beginning of a flood is detected. , and this before the fluids (water, mud, etc.) associated with this flood reach the base of this building.

The present invention also refers to a roller shutter for the implementation of this protection assembly, this roller shutter being economical, resistant and offering a watertight closure of the opening it condemns.

Another object of the present invention is a particularly simple and reliable method of protecting a building against flooding, which guarantees an effective protection of this building against flooding.

Brief description of the invention

To this end, the invention relates to a flood protection assembly for a building according to claim 3.

Advantageously, therefore, the security zone at least partially surrounds the building to be protected and is determined in terms of its spatial extent, preferably in order to guarantee the complete deployment of each protection equipment with which the building is equipped before that these fluids reach the base of the building. In fact, it is observed that the opening caulking devices of the state of the art are ineffective because they are deployed too late, the fluids associated with the flood being already in the building to be protected when they start to activate.

Thus, by way of illustration only, at least some of the detection means may be located outside the security zone, for example in an exterior zone contiguous to it and, therefore, further from the building than said security zone.

Certain means of detection, such as CCD cameras, can make it possible to obtain images of an area of interest located beyond the security zone in such a way that the latter are not necessarily located outside the security zone or the building.

Preferably, these detection means are autonomous and independent so that each one sends its data to the central unit. Advantageously, the deployment of each piece of equipment will be automatic when the start of a flood is detected by the detection means or means. Alternatively, when these detection means are multiple, one or more of them can be placed in a network so that the detection of the presence of water or of an abnormal level of water by a measuring device leads to the activation of one or more of them. various of other measuring devices, put on standby to save battery or energy consumption, in particular when not connected to the electrical network, to confirm or invalidate this presence of water or an abnormal level of water outside the safety zone. A confirmation stage of the existence of this flood can then be provided before the deployment of each protection team by the central unit, in particular when the arrival of fluids associated with the flood shows that the latter is slow.

According to the invention, said watertight roller shutter body is inflatable.

According to the invention, at least the lateral edges of the watertight roller shutter body are inflatable, the central part of the roller shutter body comprising a flexible wall that can be reinforced with rigid reinforcement elements, or stiffeners, spaced apart from one another. These mechanical reinforcing elements can be reinforcing slats or bars received in housings provided for this in the flexible wall. The flexible wall can be multi-layered and comprise a protective outer coating such as a carbon/Innegra® type fabric.

In different particular embodiments of this protection assembly, each one having its own advantages and susceptible to numerous possible technical combinations:

- said detection means are chosen from the group comprising at least one imaging device, at least one means for retrieving meteorological data, in particular rainfall data (quantity, spatial distribution) in a geographical region of interest, at least one pluviometer , at least one water level sensor, at least one radar level sensor ("radar level gauge" - "RLG") that allows non-contact measurement of a water level and combinations of these elements. Preferably, said detection means comprising one or more imaging devices, said central unit comprises an image analysis device configured to detect in the images acquired by said imaging device(s) the presence of an abnormal water level such as a wave.

- Each sealed roller shutter is monobloc.

Each roller shutter is therefore mechanically more resistant to the aggressions associated with its use.

- said shutter body presenting a longitudinal dimension greater than said pair of guides intended to be fixed on said wall, each watertight roller shutter comprises a free end capable of adopting a first unfolded configuration in which it can be inserted into said guides and a second configuration so-called unfolded in which, when inflated and placed protruding from the lower ends of said guides, the shape and dimensions of said free end of said roller blind lock it in position against the free ends of said guides.

As said guides are judiciously placed on both sides of a corresponding opening, this free end of the roller shutter can end up wedged between said guides and the ground to guarantee sealing on the ground.

Good sealing is thus obtained at the base of an opening without it being necessary to arrange a rail in the lower part of this opening and thus facilitate the passage of users at the level of this opening when it includes a door or a leaf and the equipment protection is not activated.

Alternatively, as each protective equipment comprises an anchor rail, each watertight roller shutter comprises a free end intended to be received in the corresponding anchor rail, this anchor rail comprising a base from which two lips depart, said free end being susceptible of adopting a first unfolded configuration in which it can be inserted in said anchor rail and a second configuration called unfolded in which, when inflated, the shape and dimensions of said free end lock it in position in said anchor rail.

Each anchor rail is intended, for example, to be applied to said wall or to be fixed to the ground.

Advantageously, one or more anchor rails can be pre-installed, for example by burying them at least partially to level or flush with the rest of the surrounding ground, in particular at the level of a passage.

Preferably, said free end comprises at least one longitudinal shaping element to shape said free end when it is inflated and guarantee its anchoring in said rail or in the end of said guides.

This shaping element is placed, for example, inside the free end.

- Each protection equipment includes an autonomous power supply located in said box for its power supply in the event of a general power outage,

- this assembly comprises a central alarm device to which said central unit is connected, said central unit being configured to activate said alarm device during the start of a flood to warn the person or persons present in the building and/or in the outer security zone.

This alarm device may comprise a device for emitting an audible and/or visual signal.

- Said central unit comprises a wired or wireless communication means to send at least one alert message to a mobile communication terminal of the owner of the building and/or to an emergency center. For illustrative purposes only, said at least one alert message is sent via an Internet network or a communication network.

For example, this transmission may implement a cellular access network comprising a set of cellular access points to which a terminal used to transmit this or these images is connected. The cellular access network can be of various types (2G, 3G, 4G), each type of network being able to be accessed according to various cellular access technologies (2G: EDGE, GPRS, 3G: UMTS, HSDPA, HSUPA, HSPA, HSPA+, 4G: LTE). Alternatively, it may be an Internet network, a network comprising non-cellular wireless access points such as a WLAN network, for example Wi-Fi or WiMAX, or even a Li-Fi network.

- Said central unit is configured to guarantee the simultaneous and instantaneous deployment of each protection equipment with which said building is equipped.

By "instant deployment" is meant, in the sense of the invention, the sealing of an opening by the watertight roller shutter of the corresponding protection equipment in less than the time necessary for the fluids associated with said flood to travel through the safety zone. and reach the base of the building, for example in the order of thirty (30) seconds.

The present invention also relates to a flood protection system for at least two buildings.

According to the invention, each building comprising a set of protection against floods as described above, said central units are connected to each other in such a way that the detection of the beginning of a flood by a first central unit, activates the deployment of each team of protection. protection with which the building(s) managed by the other central unit(s) is equipped.

The present invention also relates to a roller shutter according to claim 1.

According to yet another aspect of the blind of the invention, the free end of said roller blind comprises at least one longitudinal shaping element to shape said free end when it is inflated and guarantee its anchorage in said rail or at the end of said guides. .

The present invention also relates to a method of protecting a building comprising at least one opening, said building being equipped with a flood protection assembly as described above.

According to the invention, the following steps are carried out:

a) define a security zone around said building,

b) monitor the presence of an abnormal water level in an area of interest outside said security zone, and eventually

c) retrieve rainfall data (quantity, spatial distribution) relating to a geographical region of interest, spatially more extensive than said security zone, for n instants, where n is an integer strictly greater than 1, to estimate a flood risk factor , Y

d) activate each protection equipment when the beginning of a flood is detected in said area or region of interest.

According to one aspect of the method of the invention, the activation of each protection equipment of said building is carried out simultaneously.

According to another aspect of the method of the invention, in step b), at least one of the following operations is carried out:

- acquiring images of at least one area of interest located outside said security zone, analyzing said images to detect in them the presence of an abnormal water level, such as a wave,

- obtaining data on the presence of an anomalous water level in said area of interest.

According to yet another aspect of the method of the invention, the data on the presence of an anomalous water level is determined from at least one detection means located at the limit of the security zone.

Detailed description of the invention

First, it is noted that the figures are not to scale.

The flood protection device is composed of three main elements:

- First element: a watertight barrier, formed by a curtain that unrolls.

A membrane with its components, flexible, elastic, light, like those used to make cisterns for the recovery and storage of rainwater.

Made of EPDM, a material of remarkable qualities, it allows the tanks thus constructed to combine solidity, lightness, elasticity while benefiting from an exceptional useful life.

EPDM membranes are used in construction, industry, the residential sector, but also in many industrial processes.

This type of membrane or its equivalent will constitute the watertight barrier against flooding itself; it will in turn be protected on its entire surface by a carbon/Innegra® type fabric. In the family of hybrid technical fabrics, the carbon/Innegra® fabric benefits from the best flexibility/resistance/weight ratio.

Made with an epoxy resin, it provides a very high resistance to shocks and violent impacts, much higher than a carbon-Kevlar fabric.

The casing thus made has a series of rigid bags (figures 1/6 and 2/6) that are completely sealed, all the welding being done by vulcanization; the finished thickness of this membrane of the order of 2 mm, gives it characteristics of high performance, durability, ultra-resistance and indestructible. After vulcanization and gluing, the assembly forms a single homogeneous material.

When the width of the watertight barrier is greater than a certain dimension, the EPDM watertight membrane is reinforced. It is made up of two strips, placed one on top of the other, in which a strip of raw EPDM tape is inserted that will allow vulcanization to be carried out by crosslinking; fusion of molecules of matter with each other.

This membrane, once brought to useful dimensions, will be protected, on the visible sides, as already indicated, by a carbon/Innegra® type fabric.

The watertight barrier can also be made up of other components such as Yamamoto® Japanese neoprene with trilaminate fabric or Cordura®, a material that has good tear and abrasion resistance while retaining good flexibility.

Professional grade XPR 900g PVC banners can also be used.

If the characteristics of these canvases are observed, one has:

Material: PVC (poly(vinyl chloride)), thermoplastic polymer

Weight: 900g/m2.

Fabric: 1100 dTex coated polyester.

Tear resistance of 60/50 daN.

Breaking strength of 420/480 daN.

Cold resistance of -30°.

70° heat resistance.

The membranes that make up the 900 gr PVC coated polyester plastic tarps are tear-resistant, waterproof and rot-proof.

Regardless of the choice of material chosen, the structure (i.e., the rigid assembly) of the created barrier curtain is made by installing, incorporated into the membrane, aluminum or steel stiffening tubes (figure 1, page 1/6 and figure 2 , page 2 /6).

These tubular reinforcements will make it possible to guarantee the efforts experienced by the flow of flood water and the various forces produced by the current, the transported objects and possible eddies.

These stiffening tubes placed at defined intervals (figure 2, page 2/6) also maintain the correct width of the barrier; its height being defined by the programmed tension of the belts under the control of tensiometers; suspension straps that support the watertight flood barrier.

At certain intervals, these aluminum or steel tubes allow the barrier curtain to be perfectly maintained and guided during its operational start-up.

System programming will direct the barrier curtain to lower as needed:

- By setting the drum carrying the sealing barrier curtain in downward rotation where it was rolled up.

- From its descent to contact with the ground, guided by the two U-profiles provided for this purpose and placed on both sides of the opening to be protected.

- The vertical translation guides of the barrier described above will be made of aluminum sheet forming a U (figure 3, page 3/6 and figure 4, page 4/6) of 60 * 60 * 5 or 90 * 100 * 10. some installations these dimensions of the U may be different.

On both sides of the wings of the U, sliding elements of Cestidur® or material with the same sliding and resistance qualities will be positioned, preferably maintained by gluing.

- Second element: the drawer with its equipment and mechanisms.

The upper part is made up of a protected galvanized sheet metal box or other protections according to convenience and aesthetics (figure 5, page 5/6).

It will contain the watertight barrier lowering/raising translation equipment, made up of a motorized tube carrying the barrier curtain winding drum; the selected electric motor is the Somfy® Sunea io motor or its equivalent. It is placed inside the tube; this motor is programmed to stop and raise the barrier curtain again if it encounters an obstacle; This motor, widely used for the operation of automatic roller shutters or shutters, is controlled, as is the chosen camera, by io-home control.

The box will contain the compressor to apply air pressure or air vacuum, the peripheral gasket according to system programming; its pressure setting will block the barrier at the bottom when it is unrolled, the air vacuum will unblock it; the height of the barrier is maintained according to programming by the suspension straps.

The weatherstrip is characterized by the fact that it forms an integral part of the membrane that constitutes the barrier curtain. The membrane forms a single piece assembly. It is a single weatherstrip that acts on each of the three vertical sides of the support guides and on the lower part in contact with the ground when it is put under pressure. It guarantees vertical and ground tightness through its inflation that remains constant and controlled according to programming.

The left and right U-guides will have their upper end widened (figure 5, page 5/6) to form a sink that facilitates, during the unrolling of the flexible barrier, an easy passage for its movement. These guides will fit a few cm into the drawer.

The first element that constitutes the lower part of the barrier curtain is hooked, when raised, a few centimeters in the upper part of each of the guides (figure 5, page 5/6).

This first element, the one in contact with the ground (figure 6, page 6/6) is different from those placed at regular intervals in the cavity of the waterproof membrane. It does not comprise a 30 mm diameter steel or aluminum tube, but rather a flat bar (beveled corners) of 70 * 30. It is followed by a hard steel hinge element (figure 6, page 6) formed by two mobile wings that are kept apart by a return spring.

Due to its shape and location, this component guarantees two main functions:

- the lower curtain/floor tightness, as well as the locking of the barrier assembly in the lowered position when it is put into operation (figure 6, page 6). This essential locking makes it possible, when the weatherstrip part is inflated, to guarantee the necessary pressure for a good seal between the weatherstrip itself and the concrete on which it rests. Without blocking, the weight of the barrier alone will not allow a true seal, the barrier may move upwards due to the vibrations received, thus creating water leaks. Inside the drawer will be placed all the other useful components:

- 1- The air compressor, to inflate or deflate the weatherstrips designed with the same membrane in the same part as the one that guarantees the watertightness of the barrier curtain.

- 2- The 12 or 24 volt battery that guarantees the necessary energy for the different functions.

- 3- The drawer of general operating programs that allows the device to carry out its mission of protection against flood risks without human intervention.

- 4- The site monitoring camera under the control of io-home control.

- 5- The location, visible from the outside, of the two flashing lights that warn of the lowering of the barrier curtain.

- 6- The casing of the drawer or window, if any, will serve as a support for the photovoltaic panels for energy production for charging and maintaining the charge of the mentioned battery.

- 7- The io-home control casing, a new wireless, universal, secure communication protocol shared with the main manufacturers in the home world.

lo-control allows all comfort and safety equipment to communicate with each other and be controlled by a single control point.

lo-homecontrol allows to support the evolution of the needs of a house: roller shutters, entrance door, external shutters, gate, garage door, garden lighting, flood protection device, etc. The user can manage the different functions of their installations in a personalized way; It receives real-time feedback on its control orders and perceives warning signals in the event of unforeseen events. This home automation option provides comfort, security and energy savings on a daily basis by making all the equipment in the house effective and efficient, managed locally or remotely.

The proposed Sunea io engine also uses io-homecontrol.

- 8- The set of cables, signals from rising water sensors, redundant for double security with the camera monitoring software that informs if this is the administrator's choice. - Third element: possible installation of a window over the entrance door.

Four important criteria serve to define the features and optional options of such a device: - aesthetic, integrated drawer.

- Sufficient space for installation.

- Choice of the window that allows its installation.

- client budget.

The flexible watertight barrier curtain as described is perfectly suitable for widths of opening to be protected less than 2 meters.

If the dimensions of the opening to be protected against flooding, such as private underground parking ramps, public underground parking or other needs that require protection are between 2 m and 4 m, the flexible barrier curtain can be replaced by a metal curtain arranged on the same principle as the flexible curtain indicated above.

The curtain that forms a watertight barrier will in this case be made up of stapled two-layer steel slats, with interior insulation, phenolic foam or another identical one, the purpose of this insulation being to dampen noise, without reducing flexibility or lightness of each slat but improving the rigidity of each of them. Watertightness will always be guaranteed by means of EPDM membrane applications adhered to the stapled double-skin steel slats, reinforced and protected in the same way as the description already made, with carbon/Innegra® fabric.

The lower sealing by means of the inflatable weatherstrip resting on the ground, the vertical sealing by means of the inflatable weatherstripping supported on the guide slides.

The inflatable weatherstrips are always made with the same membrane that only forms a single piece (figure 2, page 2/6).

These stapled slats are wound on a steel drum driven by a chain and toothed wheel, integrating the assembly into a larger drawer, a drawer that includes the same useful auxiliary elements indicated above.

Summary of the invention:

Flood protection device formed by a flexible curtain that characterizes it, permanently installed watertight reinforced curtain; rolls up and unrolls; at rest, it is rolled up on a drum housed in a box above the opening to be protected; automatically unrolls as soon as a risk of flooding is detected; guides on both sides of the opening keep it in its correct place, sealing the guides/curtains through the automatic inflation of peripheral weather stripping.

This flexible waterproof flood curtain is characterized by its specificities of adaptation to the dimensions of the openings to be protected; for small widths, the specified membranes of reinforced EPDM or equivalent material are maintained by steel or aluminum reinforcements inserted into them; for greater widths, the membranes are placed on stapled two-layer steel slat supports. Flood protection device that is characterized by its peripheral weatherstrips that guarantee, when put under air pressure, the tightness between the membrane and the guides, in turn fixed to the walls that frame the opening to be protected against water floods.

The peripheral gaskets are not added, what characterizes them is that they are an integral part of the membrane against flooding that constitutes the sealing of the opening to be protected, the membrane and the peripheral gaskets form a single piece that guarantees vertical and floor simply by putting it under air pressure by the compressor provided for it.

The air compressor, started automatically according to programmed instructions, is characterized by its two main functions; put the weatherstrips under air pressure so that they guarantee, once under pressure, the tightness of the device, but also empty them by sucking out the air they contain to unblock the flood barrier as soon as the risk of flooding disappears.

Locking at ground level of the device against flooding that characterizes it by the longitudinal hinge system held open by a low force spring; the two sides of the hinge wings separate when the weatherstrip in question is put under air pressure, thus locking the entire device on the ground; the support straps are automatically tensioned by rotation of the drum according to defined needs.

Device against floods that is characterized by its autonomy in terms of electrical energy produced by its own photovoltaic cell plant in sufficient quantity for its operation, without any other connection; This electrical independence that characterizes it eliminates all risks due to unforeseen power outages from the official distribution networks.

The rotation of the lowering/rising drum, characterized by the choice of its drive motor, of the Sunea-io type or equivalent, also uses io-control, as does the camera installed in the drawer. This protocol of wireless, universal and secure communication characterizes the management of the entire device, allowing the protected area, the water level, the device against flooding to be displayed in place by smartphone.
