Description

The invention relates to a flexible flood protection system for a building according to the features of patent claim 1.

Certain settlements on rivers and coasts are increasingly flooded by floods. If water penetrates into buildings due to the increased water level, damage is not only caused to the interior fittings but also to the entire building fabric in the longer term. Damage to the environment can occur when contaminated water such. B. fire-fighting water in industrial fires uncontrolled in waters or groundwater, flows.

Known measures against a temporarily increased water level are stacks / planks or dykes from sandbags. These allow smaller amounts of water to seep through, can be scoured and require a time-consuming build-up before the flood and removal after the flood. In addition, such protective measures can only be adapted to changing flood levels with a great deal of work and time. Therefore, systems are required which locally protect the entire structure, are flexibly adaptable to changing flood levels and, if necessary, can be set up quickly and easily.

Out DE 20 2008 012 907 U1 a system is known in which a building is protected by means of a foil. There is a channel around the building, in which the foil is stored and, if necessary, can be pulled up by the building. The disadvantage here, however, is that the film can be pulled up and fixed only with great effort on the building.

Out EP 1 528 187 A1 Another flood protection system is known which protects a building by means of a film. A portion of the film is permanently attached to the waterproof substructure of the building to be protected. If necessary, another section of the film is attached to it and attached to the building. The disadvantage here proves the great effort in attaching the film to the building.

DE 39 05 660 A1 discloses a sealing device of building openings and land enclosures for flood protection. In this case, a collapsible Abdichtkissen of elastic material is held together in the rest position in a container and mounted below the building opening in the outer area. The Abdichtkissen is divided several times. In the case of use, first the lifting chamber and then the pressure chamber are filled with compressed air. In the application, the Abdichtkissen is inflated via a permanently installed air duct and pressed into the end position. A disadvantage here is that the sealing device is limited only to individual building openings and can not straighten the Abdichtkissen in case of damage to the lifting chamber. Another generic inflatable barrier is off DE 101 11 905 A1 known.

Out DE 10 2010 046 504 A1 is a generic inflatable barrier known for flood protection. The protective barrier is arranged in a U-shaped channel system and consists of several air-filled hoses in a steel or plastic net, both of which are anchored in the channel system.

Out EP 0 586 364 A1 is a generic flood barrier known. This protective wall consists of several cylindrical air chambers, which are surrounded by a protective cover. The air chambers are stored in a channel around the protective building. If necessary, the air chambers are filled. The protective wall is on the building side if necessary on supports, whereby the protective barrier is maintained.

All known flood protection systems have the disadvantage that they are not modular, d. H. can not be adapted individually to the building structure / building floor plan and thus protect the entire building complex and that they no longer provide sufficient protection in the event of a leak. In addition, they can not be easily and flexibly adjusted to changing high water levels.

The object of the invention is to provide an improved flood protection system in the sense of an integrated overall system, which invisibly embeds / stored at rest in ei-nem, laid around the building to be protected channel system and in case of danger with little effort ready and easy to changing Flood level is customizable and thus eliminates the disadvantages of the prior art.

This object is achieved with the flood protection system for buildings according to the features of the valid claim 1. Advantageous embodiments of the invention are the subject of dependent claims.

A flood protection system is proposed for a building comprising a protective wall and a channel system for receiving the protective wall when not in use, wherein the protective wall comprises a plurality of interconnected flexible, inflatable tubular elements, in particular cylinder and / or box and / or pillow-shaped tubular elements and the protective barrier from a foil is wrapped. The flood protection system according to the invention is characterized in that the protective barrier is made up of several air chamber modules, which are individually and separately inflatable, wherein a plurality of tubular elements form an air chamber module, in particular the air chambers of an air chamber module. The flood protection system according to the invention is further distinguished by the fact that the film which covers the protective wall is connected to a watertight substructure of the building. The film is designed as a protective film for the tubular elements and the air chamber modules, ie as a protective film for the protective barrier.

An advantage of the flood protection system according to the invention is that it is designed to be flexible and encloses the entire building or the building to be protected by water-impermeable. In addition, the inventive flood protection system can be individually adapted to the building structure or the building floor plan. It is possible that the flood protection system is individually expandable. Due to the modular design of the flood protection system according to the invention, individual components of the flood protection system are independently exchangeable and expandable. So it is z. B. possible to adapt individual protective wall elements according to the building floor plan or changes in the building floor plan, z. B. by correspondingly angled tubular elements, which can be joined together according to building corners angled air chamber modules.

In order to protect the building against contact with water (flooding or groundwater rising due to flooding), buildings with a cellar of a well-known construction, known as the "Schwarzer Wanne", d. H. equipped with sealing membranes outside or inside the building, which enclose the entire invisible structure (foundation, basement) or "white bathtub" d. H. built with waterproof concrete and joint tape. The flood protection system according to the invention is characterized in that the protective wall by means of the film enclosing the protective wall (visible part of the building) with the waterproof substructure (invisible part of the building) is impermeable to water. This ensures that no ingress of water into the structure can occur.

Another advantage of the proposed flood protection system is that the height of the protective wall formed by the air chamber modules flexible, depending on the expected high water level, can be adjusted gradually. So it is z. B. possible that the individual air chamber modules can be inflated sequentially depending on the high water level. This represents an individual adaptation of the protective wall to the current and expected high water level.

In addition, the protective wall continues to provide sufficient protection for the building to be protected if an air chamber module is not inflatable due to a defect. By a corresponding high number, z. B. five or more air chamber modules at a height to be protected of up to 3 m, each air chamber module forms quasi a redundancy for another air chamber module. By inflating individual air chamber modules, the protective barrier is formed.

The individual tubular elements and the film expediently consist of plastics, for. As PVC or coated polyester fabric. The film can z. B. be a rubber sheet. In particular, the materials used in the tubular elements or films are light and weather resistant.

The protective barrier of the flood protection system according to the invention is constructed of a plurality of air chamber modules and a plurality of tubular elements, wherein a plurality of tubular elements, for. B. form five tubular elements, an air chamber module. The individual air chamber modules are each individually inflatable by inflating the tubular elements forming the air chamber module. The tubular elements of an air chamber module are interconnected, as known in a conventional inflatable air mattress, and inflatable together. The individual air chamber modules are connected to each other by means of an adhesive or welded joint and inflated separately.

In one embodiment, the individual cylindrical tubular elements of an air chamber module are arranged in series. The series runs in the longitudinal axis of the tubular elements and adjacent tubular elements are in this connection. In other words, the individual tubular elements lie in a plane next to each other and adjacent tubular elements are connected to a common, contacting surface line, z. B. glued, welded. Along this generatrix openings are made between adjacent tubular elements, so that the tubular elements of an air chamber module form a coherent, with air or other gas, fillable volume.

In a further embodiment, the individual air chamber modules are in one plane arranged side by side. The individual air chamber modules are welded or glued together. In contrast to the tubular elements forming the individual air chamber modules, the volumes enclosed by the individual air chamber modules are not coherent.

Suitably, the film on the building and / or water-facing side of the protective wall reinforcements. These gains can be z. B. additional air chambers or introduced into the film metal elements. On the water side, these reinforcements serve to prevent flotsam driven by the flood from damaging the individual tubular elements. On the building side, the reinforcements serve to prevent movement of the protective wall on the building wall caused by the movements of water from damaging a hose element.

In a further embodiment, the film encases the protective barrier, wherein the film is in direct contact with the outer surface of the individual tubular elements. The film is firmly connected to the outer surface of the tubular elements, z. B. glued or welded.

In the present invention, a distinction is made between a casing and a casing. In a wrapper is a loose connection between the shell material, z. B. a film and the material to be wrapped, z. B. tubular elements, as it is z. In EP 0 586 364 A1 is described. In a jacket, the shell material is firmly connected to the outer surface of the material to be wrapped, so the protective wall. The wrapping material thus forms a kind of reinforcement of the protective wall. In the invention, the film thus serves, on the one hand, to hold together the protective barrier with its air chamber modules. On the other hand, the film also reinforces the individual tubular elements, as by the solid compound, for. As bonding or welding, the jacket of the individual tubular elements is reinforced. This brings further advantages with respect to a mechanical stability of the protective wall with respect to external influences.

In a further embodiment, the protective barrier is fastened to a weight element. This weight element is in the channel system, which surrounds the building to be protected, or firmly anchored in the channel system. In addition, the weight element is covered by the film. This brings further advantages in terms of a watertight connection of the film to the substructure of the building.

In a further embodiment of the invention guiding and supporting elements are provided for the protective wall, which can be set up, if necessary, around the building to be protected, in particular in the area of terraces, staircases and / or exits or window fronts. The guide and support elements serve to ensure the stability of the inflatable protective barrier when erecting the protective wall.

In a further embodiment, an air filling unit is provided, from which air supply lines are routed to each individual air chamber module of the protective wall. Suitably, this air filling unit is integrated in the building to be protected. The air supply lines are appropriately suitably sealed from the interior of the building to the air chamber modules introduced. The air filling unit is expediently additionally designed as a control and monitoring unit with which the filling or emptying of the individual air chamber modules can be controlled and malfunctions detected and output by means of a warning message.

Suitably, each air supply line to a single controllable valve, which controls the supply and removal of air to the corresponding air chamber module. The individual air chamber modules are appropriate individually, in particular successively and independently with air, z. As compressed air, another gas or a liquid filled. In addition, it is possible that the individual air chamber modules with different pressures (according to the respective flood levels) are filled. This is z. B. therefore necessary if an air chamber module due to high load from the outside, z. B. flowing waters and flotsam, must be inflated more.

Instead of building up emergency ramps, walls and waterproofing in the event of danger with high logistics and personnel costs, the flood protection system according to the invention provides an inconspicuous but permanently deployable and quickly activatable protection system which is flexibly adaptable to the respective building and flood situation and at the same time operationally reliable.

The invention and further advantages will be explained in more detail with reference to figures. Show it:

1 a perspective view of a building / building,

2 a schematic representation of an exemplary protective wall in case of danger in sectional view,

3 a schematic representation of a flood protection system at rest,

4 a schematic representation of a flood protection system with a protective barrier in flood in a sectional view,

5 a schematic representation of a building floor plan in plan view.

1 shows the perspective view of a building or building. The building to be protected 2 has a waterproof tub system 5 on. This bathtub system 5 can z. B. be a waterproof concrete cellar or sealed with a waterproof film basement. The tub system 5 prevents floods or rising groundwater from touching the wall of the building, possibly leading to the interior of the building 2 can penetrate. Around the building 2 around, is a channel system 4 in which a deployable protective wall 3 is stored from a foil material. In the event of danger, the protective barrier is inflated plane-by-layer by filling the air chamber modules with air, depending on the expected flood level. The barrier 3 is water impermeable with the tub system 5 of the building 2 connected.

The barrier 3 consists of the air chamber modules 8th , which are identified by the reference symbols A, B, C, D, E. Exemplary are in 1 the air chamber modules A, B, C filled with air and deployed. The possible through the air chamber modules D and E protective height of the protective wall 3 is indicated by the corresponding dashed lines.

The channel system 4 is when not in use the protective wall 3 , with sealing lids 17 ( 3 ) for the channel system 4 covered. This ensures that there is no damage to the protective wall 3 when not in use comes.

The flood protection system 1 to protect the building 2 thus consists of the tub system 5 of the building 2 , the protective wall 3 and the channel system 4 for receiving the protective wall 3 at rest. In addition, around the building 2 around at sensitive points (building entrances or exits, building openings) or terraces guiding and supporting elements 6 for the protective wall 3 arranged. At these points assume the leadership and support elements 6 the house wall function, by showing the water pressure on the protective wall 3 at floods, catch. In this way, sensitive components such. As doors, windows, staircases or exits and terraces especially protect without affecting the operation of the overall system. At the same time, it offers flexible application of the flood protection system to a wide variety of structures and building forms.

These guiding and supporting elements 6 in case of danger at the sensitive places in the gutter system 4 provided for this purpose sleeve elements 19 plugged in.

The flood protection system 1 especially during the completion of the building 2 be installed. But it is also possible that an existing structure with the flood protection system 1 is retrofitted. Inside the building 2 or in a watertight container outside the building 2 is a unit 7 arranged for air filling, control and monitoring of the air filling. This unit 7 is via air supply lines 13 ( 2 ) with the inflatable rampart 3 , in particular with each air chamber module 8th the protective wall 3 connected. Suitably, the unit comprises 7 a control device which manually or automatically the protective barrier 3 filled with air in case of danger and a monitoring unit for monitoring the functional condition (air pressure control). Malfunctions are signaled by warning messages and can be eliminated immediately. Furthermore, the air filling, control and monitoring unit 7 designed so that when dismantling the protective wall 3 the air from the protective wall 3 can be sucked out, so that the protective barrier 3 folded again and in the channel system 4 can be stowed.

If necessary, ie in the impending flood event, in a first step, the cap 17 ( 3 ) away. This can be done either manually or automatically. Subsequently, first the lower air chamber module A is filled with air. As a result, the first air chamber module A unfolds, creating a protective barrier 3 is formed, which is around the entire building to be protected 2 sets. In next steps, the air chamber modules B, C, D and E can be filled with air in succession. This will be the protective wall 3 higher and can be adapted to the respective flood situation. Suitably, the filling of the individual air chamber modules A, B, C, D, E takes place in succession, ie only after complete filling of an air chamber module is the adjacent, higher air chamber module filled with air. The filling of the individual air chamber modules A, B, C, D, E takes place, as already described above, by means of the air filling unit 7 , This unit 7 is in this case designed such that during the filling process of the individual air chamber modules A, B, C, D, E continuously the pressure in the individual air chamber modules A, B, C, D, E is over-wacht to a rupture of the individual air chamber modules A, B, C, D, E to avoid.

2 shows a schematic representation of an exemplary protective wall in case of danger in a sectional view. 2 shows an air chamber module 8th in case of danger, ie the air chamber module 8th is filled with air. The flexible, inflatable air chamber module 8th is in 2 by way of example four tubular elements arranged in series 9 shown. The individual tubular elements 9 of the air chamber module 8th are stacked one above the other and connected to each other. These are between adjacent tubular elements 9 perforations 16 present, whereby the air chambers of the individual tubular elements 9 are connected. An air chamber module 8th thus includes a contiguous volume of air to be filled.

Adjacent air chamber modules A, B are connected to each other airtight. For this purpose, the upper hose element 9 the air chamber module A with the lower hose member 9 of the adjacent air chamber module B (of this air chamber module B is the sake of clarity, only a tubular element 9 pictured). However, this connection is in contrast to the connection of the tubular elements 9 within an air chamber module A o the B is not continuous, ie air can not flow from an air chamber of an air chamber module A in an air chamber of an air chamber module B. These are adjacent air chamber modules 8th connected by means of welding or adhesive connection.

The barrier 3 comprising a plurality of air chamber modules 8th is from a slide 10A , in particular a protective and / or sliding foil, encased. Enclosed means here that the film 10A with the outer circumferential surface of the individual tubular elements 9 connected, z. B. glued or welded. This will provide a reinforcement of the individual tubular elements 9 reached.

In the slide 10A are reinforcements 18 brought in. These are on or in the slide 10A on the building 10A facing side G of the protective wall 3 and / or on the water-facing side W of the protective wall 3 reinforcements 18 educated. For clarity, the reinforcements 18 only on the upper tubular element 9 of the air chamber module A drawn. These reinforcements 18 can z. B. additional air chambers or in the film 10A be introduced metal elements. Through the reinforcements 18 Can the slide slide 10A along the building wall of the building 2 be relieved. On the water side W, the reinforcements provide additional protection of the protective wall 3 from flotsam in flood.

The barrier 3 consisting of the individual tubular elements 9 and the foil 10A is in particular made of plastic or rubber materials o-the polyester fabric. The barrier 3 is made in particular of water-impermeable, oil and chemical repellent, UV-resistant, weather-resistant and mechanically resistant material.

The barrier 3 is with a weight element 11 connected. This weight element 11 is with the lower air chamber module A, in particular with the lower hose element 9 the air chamber module A of the protective wall 3 connected, z. B. welded or glued. The foil 10A which the protective wall 3 encased, also encases the weight element 11 , Besides, the foil is 10A impermeable to water via a connection 15 with the tub system 5 (please refer 3 ) of the building 2 connected.

Each air chamber module 8th has a hose connection for an air supply line 13 an air filling, control and monitoring unit 7 ( 1 ) on. This unit 7 is appropriate within the building 2 arranged and the air supply lines 13 are suitably sealed accordingly from the building 2 led to the outside, so no water in the building 2 can penetrate.

Each hose connection of an air supply line 13 is with an inlet and outlet valve 14 provided with which the air supply into the respective air chamber module 8th can be regulated. It is thus possible that the air chamber modules 8th individually and separately filled and emptied again after the end of the flood.

3 shows a schematic representation of a flood protection system at rest in a sectional view. In the canal system 4 of the flood protection system 1 is a folded barrier 3 inserted. The barrier 3 hereby includes, by way of example, five air chamber modules 9 which are expediently completely emptied. The individual air chamber modules are identified by the reference symbols A, B, C, D, E, wherein the air chamber module A is the lower and air chamber module E is the upper air chamber module of the protective wall 3 represents. The channel system 4 is with cover elements 17 covered, which in case of danger, however, can be quickly removed to the protective barrier 3 to be released for commissioning.

The lower air chamber module A is with a weight element 11 connected. This weight element 11 serves in the event of danger, the buoyancy of the protective wall 3 counteract and the rampart 3 in the canal system 4 to keep. The weight element 11 is also in the channel system 4 provided fasteners 12 held.

The channel system 4 has guide bushes 19 for the guide and plug-in elements 6 on. These guide and plug elements 6 In the event of danger, they can quickly insert into the corresponding guide bushings 19 be introduced. The air chamber modules 8th are from the slide 10A jacketed. The foil 10A is from the air chamber modules 8th over the weight element 11 (see above at 2 ) to the tub system 5 of the building 2 led where the slide 10A at the junction 15 impermeable to the film 10B (dashed line) of the bathtub system 5 of the building 2 connected.

The area 20 around the guide bushes 19 for the guide and support elements 6 is against the wall of protection 3 to the tub system 5 of the building 2 guided foil 10A waterproof sealed. In other words, in case of danger, water can not be in the guide bushings 19 penetrate and from there to the building if necessary 2 approach flow.

The channel system 4 is by means of a fastener 21 to the building 2 attached. Appropriately, the fastener 21 designed such that a watertight connection is ensured and no water along the fastener 21 to the building 2 can flow.

4 shows a schematic representation of a flood protection system in case of danger in a sectional view. Exemplary is a flood protection system 1 with a protective barrier 3 from five air chamber modules 8th each with five tubular elements 9 shown in case of danger, with the flood on the water side W against the rampart 3 suppressed. Here are the air chamber modules 8th or tubular elements 9 each filled with air. The barrier 3 becomes out of the sewer system in case of danger 4 folded out. For this purpose, the air chamber modules 8th plane wise, suitably from below (air chamber module A) upwards (air chamber module E) filled with air, causing the protective barrier 3 from the canal system 4 rises out. Depending on the number of used air chamber modules 8th it is possible to realize an above-ground building protection up to 4.0 to 4.5 m. Suitably spans each air chamber module 8th in case of danger a height of 60-70 cm.

The foil 10A encases the barrier 3 , in particular, the film encases 10A the individual air chamber modules 8th , The basement of the building 2 , expedient the tub system 5 is with a foil 10B sealed. The foil 10A and the foil 10B are connected to each other waterproof. The junction of the two films 10A and 10B is in 4 by reference numerals 15 shown. The connection of these two slides 10A and 10B can be realized by means of an adhesive and / or welded connection, so that a watertight connection point 15 is guaranteed.
