Description

Description and explanation of the utility model application
"Flood protection device for buildings"

It is known that buildings can suffer considerable damage from flooding.

Not only can sludge-like masses penetrate into cellars, living spaces, garages or other storage halls, but also after the flood water has drained away, severe bacterial contamination remains on the building itself, which poses a risk to people, animals or even stored goods, especially food.

It has been found that in buildings that have been affected by flooding, up to 10 x more mushroom-shaped growths have formed in the building than in a bio-waste bin. Normally, no people are allowed to stay there until the building has been completely cleaned and denatured.

To avoid this, it is proposed to provide the structure to be protected with a pull-on and/or inflatable waterproof, elastic and at the same time stretchable skin.

This skin can be completely attached at the beginning of the foundation under the foundation plate and then provided with a sealing edge that protrudes below the foundation plate, whereby another sealing skin can be welded to this sealing edge or mechanically sealed, which has a denaturing effect, i.e. is not eaten, destroyed or stressed by vermin, so that it can be laid folded in a channel around the entire building, for example, and then, when flooding threatens, an inflatable body technology, e.g. ribs that are placed on the film, which are filled with compressed air via a small compressor or with normal tap water and then expand due to the stretching movement of the

expanding filling medium upwards to hug the building structure, even if stairs or other entrances are bridged, this must be taken into account in the design of the skin and thus encloses the entire building structure to a height of e.g. 2.3 or even 4 m, so that an absolute guarantee against water penetration into the building structure is given.

This waterproofing skin is preferably rubber-like, i.e. it can expand without tearing.

A further feature is ensured by the fact that, in existing houses, a non-floating gutter is installed around the house or the building, which is provided with a folded skin-shaped elastic bactericidal sealing body, whereby this body can be docked to the gutter itself by mechanical sealing connections via lips and screw connections or the gutter itself has an internal plastic and/or rubber reinforcement, so that it can be welded, glued or otherwise connected to the sealing skin according to the rules of technology:

in ribs that are then placed on this skin, e.g. welded on and are also flexible, the medium from a compressor and a domestic water pipe is introduced into these ribs, e.g. at 0.1 or 0.2 bar, for example via a pressure reducer, and the skin-shaped body automatically pulls itself up to the building structure to seal it.

Shutters or sharp edges must of course be replaced by appropriate non-edged bodies so that the skin can be pushed or pulled up without causing damage.

Of course, this skin can also be pulled up using mechanical means or even pulled up by hand in the case of smaller single-family homes. This sealing skin is designed to be bactericidal, so that negative influences from animals and bacteria, fungi and the like are not present.

The gutter around the house must be designed to be denatured so that vermin cannot penetrate the deposits and/or water there does not cause bacterial or germ-forming contamination for humans, animals and thus for health.

with (3) the sealing channel which surrounds the warehouse and which also serves as a disposal channel for the elastic sealing skin

with (4) the highly elastic sealing skin that is pulled up in the event of a flood alarm or can be raised using its own compressed air or water pressure bridges

with (5) the structure of a warehouse

This flood protection device shown in the drawing is intended in particular for houses or buildings made from prefabricated elements, since these are usually flooded at the connection points by flooding or are disadvantaged in terms of bacteria due to pressure influences.

Of course, the proposals are not limited to the forms of construction described and illustrated in detail above, but numerous modifications are possible without, however, deviating from the basic idea of installing a sealing skin beneath or at the lowest point of the building or a channel enclosing the building that is pulled up during flooding and thus protects the building from the negative influence of flooding, whereby this sealing, elastically deformable and highly stretchable skin is designed to be bactericidal in order to warn germs and bacteria against falling during storage and also during and after the flood.

Claims (1)

Protection claims: Claim 1 · Device for sealing building structures, characterized in that the seal consists of an elastic bactericidal skin which is preferably installed immediately when a new building is constructed under the building itself, i.e. under the foundation slab, and cantilever-shaped projections protrude from under the foundation slab and encloses the house by means of a welded or mechanically sealed connection with a skin-shaped body, whereby this skin-shaped body ends in a fold-like manner on the lower building structure and is stored in a channel or in a specially designed, beautifully landscaped depression and, according to the invention, is sealed with a bactericidal effect and/or egg-shaped overlays in a non-floating channel and/or in a trench-shaped depression in such a way that the skin can be pulled up in the event of a flood alarm, e.g. over a warehouse and/or single-family or multi-family houses, or according to the invention by means of inflatable body-shaped projections, ribbing and the like by pressurized water from the tap water and/or compressed air can be inflated so that these inflatable bodies automatically pull the skin up on the structure to be protected. Claim 2 Device for sealing building structures according to claim 1, characterized in that the sealing body is provided with a sealing device at the lowest point of the building which can be mechanically attached to the building structure itself in a sealing manner and is provided with inflatable stiffening ribs and lifting ribs specially attached to the sealing body and the building structure can also adapt to any shaped building structure in the area of stairs, entrances, etc. thanks to its generously designed and elastically acting, highly stretchable rubber-shaped skin. Claim 3 Device for sealing building structures according to claims 1 - 2, characterized in that the device is provided with a non-floating channel at the lowest point of the building structure, which is stored in the ground and itself has a bactericidal effect and is connected to the deposit of the sealing building structure skin provided with the floor channel. Claim 4 Device for sealing building structures according to claims 1 - 3, characterized in that the device can also be provided with attached eyelets and hooks with which this sealing skin can be pulled up successively around the building structure using conventional lifting and/or pulling devices, hoists and the like.
