Description

Purpose of the invention described. 1 - Allow to protect his home or other defined areas following rapid rise of water whose heights reached were not at the time of construction of the housing considered, indicated or even thinkable.

The new risks of flood even on building land seem more and more important, hence the protection system proposed below, designed mainly for private homes.

This simple implementation system provides a watertight barrier, at a given height, that takes into account the history of the highest water levels already observed, at the constructed site.

This waterproof barrier will be positioned in front of any low opening of a house, entrance door, window, garage entrance in the basement, garden gateway etc ... etc. where the inhabitant will wish to guarantee the maximum of floods with heavy consequences financially, morally painful to live, in particular when they become repetitive. 2 - Implementation of a waterproof barrier.

Three important criteria serve to define the characteristics and optional choices of such a system. 1 - The technical possibilities of installation. 2 - Desiderata of the client, the budget retained. 3 - The possibilities of commissioning the waterproof barrier. 3 - Main components of this waterproof barrier.

In basic solution, an aluminum sheet of the 5000 series; main room damming the water. Its dimensions will depend on those of the opening to protect and its location: in front or between the amounts of framing of the opening.

U-shaped profiles in aluminum sheet will be welded to the main room indicated above. These profiles will serve as housing inflatable tubes ensuring tightness between the framing walls and the main room.

Inflatable cushions: they ensure once inflated sealing between vertical walls, entrance threshold and main room damming the water.

Built-in safe: if necessary for housing secondary components.

Fixing parts of the watertight barrier assembly thus constistué. Realization: 1 - Watertight barrier installed in facade in front of the opening to be protected.

The main part, aluminum sheet thickness 4mm, 5000 series is cut to meet the dimensions of the opening to be protected, (page 1 sketch 1/5 part 1)

This flat sheet metal part 1 is folded, angle of about 45 °, on each of the vertical left and right sides according to (page 1/5 sketch 2 piece 2). (This angle is a function of the wing heights of the profiles U so that all the ends of the sheet and wings of the U, housing of the inflatable tubes, are on the same plane.Therefore the angle of folding may be slightly different.)

Corner pieces (page 2/5 sketch 3 piece 3) are welded to the folded ends to make the assembly formed rigid.

U-sections (page 2/5 sketch 4, part 4) are welded to part 2 sketch 2 page 1/5; their arrangement corresponds to the path chosen for the inflatable tubes to ensure contact with the built elements. These profiles U are arranged so as to constitute a continuous housing for the inflatable tubes. Small holes are made on each edge of the wings of the profiles U, allowing the fixation of the elastic nets holding in place the inflatable tubes, when they are empty of air ..

This set consists of hinges (page 2/5 piece 5) allowing the rotation of the panel in the same way as a conventional brace.The low hinge (page 3/5 sketch 6) will remain fixed permanently, the upper hinge will be put in place once the waterproof barrier is positioned on the bottom hinge provided for this purpose, gond securely sealed in the corresponding wall.

The high hinge (page 3/5 sketch 6) will then be put in place from bottom to top, the corresponding hinge (part 6 sketch 7 page 4/5) being reversed, its axis turned downwards.

This assembly will prevent the barrier from being able to come out of its hinges, when the low inflation inflatable bead is put under pressure; at this time, the "sandwiched" bead between the threshold of the opening and the U of its housing will exert sufficient pressure causing total sealing of the threshold of the opening.

The inflatable bead not put in air pressure is put in place, retained by the installation of elastic nets. (Sketch 6 page 3/5 part 8)

This done, if we close the waterproof barrier, it will pivot on its hinges, just as would a brace; when the barrier is completely closed, it locks automatically with its movable hooks (page 3/5 sketch 6 piece 7) tilting on the fixed receivers (page 4/5 sketch 7 part 9) sealed to the corresponding wall. This lock blocks the barrier at the height of the initial setting. This blocking also helps prevent the barrier from rising when the inflatable bead that will seal at the threshold will be pressurized air.

Once the barrier is closed, the inflatable barrier sill and the two left and right sides are pressurized with a foot pump, or any other possibility. The pressurized tubes are supported on the parts built, thus ensuring a complete seal.

This principle, whatever the width or height dimension of the watertight barrier, is that which is retained to ensure the tightness between barrier and walls built.

The closure of the barrier is done in the above explanation, manually when the rise of the water level becomes worrying; its opening, when the water level is no longer disturbing is also done manually, the locking system (page 3 sketch 6 parts 7) being released by manual action on the opening rod provided for this purpose.

The barrier is in the normal non-service position. 2 - Watertight barrier installed between the jambs of the opening.

The main piece, 4mm thick aluminum sheet, 5000 series is cut to meet the dimensions of the opening to be protected. (page 5/5 sketch 8 piece 10).

The left and right vertical sides according to (page 5 sketch 8 piece 10) of this sheet are bent, forming an angle of 90 °. The outer distance between these two sides must correspond to the width of the opening leaving a reduced clearance to position it without difficulty; the edges of the sheet forming a right angle being directed towards the interior of the room.

At the high and low ends, a 10 mm diameter hole will be made, before or after folding according to the choice chosen by the manufacturer, to allow the passage of the rod lock locks mounted at each of the top and bottom corners of the barrier plate made . (page 5/5 sketch 8 pieces 11)

The housing of the inflatable tubes are positioned opposite to the bolts, so that the wing of these U allows the inflatable tubes to be opposite the masonry portion of the frame of the opening and its threshold; (page 5/5 sketch 8 piece 10).

The elastic threads for holding the strands are then put in place. The sealed barrier is operational. It will be sufficient to put it in place when the water level reaches a warning height.

The barrier is held in good position by the four locks, which will fix it, themselves being once in the locked position thus maintained by a pendulum blocking, preventing it from changing position.

The tubes are inflated according to the recommended pressure indications, by a foot pump or any other preferred solution. 3- Use of existing possibilities.

When an opening that is to be protected from rising waters, is already equipped with a conventional brace, it is possible, if it is in good condition, to use it as the main basis of the sealing system .

If the inner part of the brace has a Z reinforcement, (scarf 7 page 2/5) it will be removed. On the face of the breather from the outside when it is open) will be glued a sheet of polyester.If it is necessary to reinforce the resistance of this part of the weakened flap by the removed part, at the end of setting up the components ensuring overall waterproofness, additional stiffeners will be added.

On the side of the brace (when viewed from the outside when it is open) a sheet of polyester or other satisfactory product will be glued to a height corresponding to the maximum level of water intake retained.

This part of the shutter will become waterproof.

U-shaped aluminum profiles cut to the right dimensions will be positioned around the perimeter of the polyester sheet so that when the tubes are in place and then inflated, they come to bear on the solid part of the frame of the opening considered. Fixed by screws or rivets, they will serve as housing deflated and inflated blood sausages.

When they are at rest, ie not inflated they are held in their housing by elastic nets, themselves attached to the wings of U concerned.

If a risk of rising water is announced, the flap to ensure tightness will be closed and then locked manually by the inhabitant of the housing.

With a manual foot pump or any other model, the tubes will be inflated to the pressure provided for this purpose. They will rely on the solid part of the frame, guided by the wings of the path formed by the U aluminum set up. Watertightness is thus ensured, the water can not penetrate through this opening.

This safe and economical solution can be used whenever it is convenient for the customer if the equipment of the closures of his house are in good condition. 4- Variations and possible automations.

With the above detailed systems flooding due to rising water levels can be avoided by commissioning the chosen and installed solution, when a flood risk is reported.

This commissioning of the flood barrier is done by the inhabitant; Although it requires very little time and effort, it is imperative that the informed person be present at home when a rapid risk of rising water is reported.

To avoid this worry and constraint of a mandatory presence on the spot, it is possible according to the system adopted that the installation of the waterproof barrier is done automatically either by a given order remotely, or by the actual detection of the system installed.

This possibility of remote commissioning is feasible when the waterproof barrier pivots on hinges such as a brace. This corresponds to the watertight barriers installed on the facade of the opening, or those installed on existing shutters.

In both cases, all manual operations can be completely autonomous.

Installation of the waterproof barrier. Locking of the barrier in the closed position.

Inflating flanges ensuring tightness. 4-Secondary components necessary for the automatic setting up:

Photovoltaic cell panel + power box for battery charging.

Battery supplying energy to different electrical systems. Lock keeper and holds in the closed position of the base panel. Electric cylinder for closing and locking the watertight barrier.

Electric pump to automatically inflate the sealing beads.

Home automation box for remote control by smartphone closing the base panel.

Installation of components allowing the system to be completely autonomous.

To automate the watertight barrier bearing on the pivoting facade on the hinges sealed to the building, it is necessary to have an independent power supply, reserved for the sealed barrier.

To do this a small panel of photovoltaic cells will be positioned on the aluminum sheet in the center of the surface delimited by the U profiles that are assembled. (Page 3/5 sketch 6)

Threshold U, left and right profiles.The upper limit will be caused by the realization of a safe that will house all the additional accessories that will be cited following.

To store the energy produced by the photovoltaic cell panel, a 12 or 24 volt battery will be used depending on the type of installation. This battery will be maintained permanently under load thanks to the photovoltaic cells as long as the sealed barrier will not be in the closed position.

The battery as well as the power supply boxes of the connected elements will be housed in the trunk located above the limit zone of rising waters.

This chest is not intended to be watertight because placed above the limit of the water rise is not floodable.

Electric pump to inflate the flanges as well as other accessories will be positioned in this trunk.

The closing mechanism of the barrier will be by cylinder + chain + pinion or engine type actuators electric robo cylinder.
