Definitions

  • the invention relates to a method and an apparatus for protecting buildings against the ingress of dangerous gases, in particular radon, from the building ground, a barrier system consisting of several horizontal layers being built up between the building ground and the interior of the building, which is laterally through vertical walls of the building is limited.
  • the radon atoms are able to migrate through substances to different degrees. They come from the adjacent earth material through porous cover layers, cavities, thin release agents in the basement or living area.
  • the diffusion of the radon gas into a building is essentially dependent on the radon content in the subsoil under the building and the nature of the foundation.
  • the first method is to increase the mechanical resistance between the ground and the interior of the building. Foils, well-compacted concrete or similar materials prevent the air from moving further.
  • this method has the disadvantage that the smallest gaps in the barrier system (due to improper processing of the material, material deficiencies, changes in the material over time, e.g. due to aging, due to the effects of external forces on the barrier with the formation of cracks, etc.) have the effect decreased until completely canceled.
  • the diffusion process which is always present, increases with a consequent sealing by creating a greater pressure difference between the building site and the interior of the building, and in this way radon penetrates into the building.
  • radon-containing air Another known possibility is to extract radon-containing air under the building.
  • a vacuum is artificially built up in the ground.
  • the radon-containing air does not flow towards the building, but rather to an artificial pressure sink, a so-called radon fountain with a lower pressure. This redirects the air flow and extracts radon-containing air.
  • this process is the same as the construction of a barrier layer, with a distinction being made that simple foils of small thickness can suffice to prevent the low static pressure, while the material properties are more prevalent than the radon atoms against diffusion. However, this is much more complex.
  • the risk of radon is reduced by diluting the radon gas before the air enters the building.
  • Another form is when a specially designed cavity is created under the building through which outside air is drawn in.
  • this method does not prevent the lower radon concentrations from still being able to penetrate into the building in accordance with the air pressure differences that still exist.
  • it is also necessary to prevent the penetration of dangerous substances from structures into the ground.
  • the invention has for its object a method and an apparatus for protecting buildings against the ingress of dangerous gases, in particular radon, from the ground, whereby a barrier system consisting of several horizontal layers is built up between the ground and the interior of the building, which is laterally through vertical walls of the building is limited, which makes it possible to secure the entire building or parts thereof against the ingress of dangerous gases by convection and / or diffusion, the barrier system being arranged above the parting plane between the building site and the building.
  • the task continues to be to prevent gases from entering the building from entering the ground.
  • the object is achieved in that air is introduced into an intermediate layer lying between the passage of air and gases and an air pressure different from the ambient pressure is built up, the introduced one Air flows through the intermediate layer and exits again and harmful gases which have penetrated into this intermediate layer are thereby led out of the building.
  • the air pressure in the intermediate layer can be built up as an overpressure, but also as an underpressure.
  • the air flowing through the intermediate layer can also lead the harmful gases that have penetrated into the intermediate layer out of the building. At the same time, this prevents the penetration of dangerous substances from the building into the building ground, which meets the requirements of environmental protection.
  • the solution according to the invention comprises a device with a barrier system which consists of one or more barrier layers, an air-guiding intermediate layer having an air pressure which differs from the atmospheric pressure being arranged in a barrier layer between two layers which inhibit the passage of air and gas and which is at least with a pressure-adjustable air line is connected.
  • overpressure or underpressure can be generated in the intermediate layer via the air line.
  • the air line is designed as an overpressure line, it is expedient to arrange an exhaust air line in the intermediate layer, which connects the intermediate layer to the space outside the building and has a higher air resistance than the air line supplying the air.
  • the pressure-regulated air line can be connected to a pipeline that runs along the inner layer and has air outlet openings.
  • a further possibility is that in the air-guiding intermediate layer, the air and gas passage-inhibiting layers are connected to one another, which have interruptions serving for air circulation.
  • the lower layer which prevents the passage of air and gas, can be designed as a cleanliness layer lying on the building ground and the upper layer as the lowest floor in the building.
  • further layers can be arranged between the cleanliness layer and the floor layer, which are each separated from one another by an intermediate layer.
  • Embodiment of the invention in that a horizontal boundary layer of increased tightness is arranged on the upper and / or lower side of the air-guiding section of the intermediate layer.
  • the intermediate layer is designed as an air channel, the upper and lower side of which is formed by the boundary layer.
  • the air duct forms the upper part of the intermediate layer and rests on the upper layer which prevents air and gas passage and the lower part of the intermediate layer as one Thermal insulation is formed, which rests on the lower inhibitory layer.
  • a cost-reducing solution is that the air duct and the thermal insulation form a section, heat-insulating, air-permeable material being arranged in the air duct and the upper and lower boundary layers being arranged on the outside thereof.
  • a solution is particularly suitable for residential buildings in which underfloor heating is arranged in the intermediate layer.
  • a preferred solution for forming the air channel is that the webs are firmly connected to one of the boundary layers or to both boundary layers.
  • the air duct can be rolled out from one or more Plastic films is formed. The assembly times are reduced by using prefabricated parts.
  • guide webs serving for air guidance are arranged in the section of the intermediate layer designed as an air duct.
  • the boundary layers between the foundation and the wall can be arranged as a horizontal barrier layer.
  • boundary layers are horizontally integrated into the wall adjacent to the barrier layer, a spacer layer being provided and a privacy screen in the form of a baseboard.
  • a spacer layer being provided and a privacy screen in the form of a baseboard.
  • the device according to the invention is designed in such a way that in a building which has a plurality of rooms arranged on the building site and separated by walls, a barrier system is arranged at least in two rooms between these and the building site, with all rooms having the are provided with the barrier layer, the air-conducting intermediate layers of which are connected to one another via air lines and have a common, central air supply via an air line.
  • An expedient embodiment is that for connecting the barrier layers of the individual rooms via the air line, a connecting piece from the intermediate layer is guided vertically upwards over the floor, a horizontal connection through the Wall takes place and then the air line is led vertically downwards into the intermediate layer of the barrier layer of the next room via a second connecting piece, with a control device for checking the content of dangerous gases in the intermediate layer under the individual rooms on the part of the air line lying above the floor is arranged.
  • the air-guiding intermediate layer of the individual rooms guide webs are arranged, through which the air from the air inlet is guided under all rooms having barrier layers, and via which air lines connecting the rooms to one another return a circuit to the air inlet is.
  • the air line at the air inlet and in the region of the section of the air line which is returned in the circuit has a control device which has an air dryer for the incoming air, a control device for checking the content of dangerous gases in the air flowing in the circuit, and a pump with pressure - or has suction for the air circulation and a check valve and a pressure limiter controlling the air outlet and the pump.
  • the barrier systems are designed differently between the individual rooms, the barrier system between the basement of a building, which is arranged on the building site, having the structure of a floor in which the lower, the air and gas leakage-inhibiting layer is designed as a sub-concrete and the upper inhibitory layer forms the screed of the floor, on which a wear layer is arranged and between the layers there is an air-bearing intermediate layer of relatively low height and the barrier system, in which a basement is arranged between the basement and the building ground is designed so that the floor of the basement the lower inhibitory layer and the The ceiling of the basement forms the upper barrier layer and the basement room itself forms the air-guiding intermediate layer, whereby the barrier systems with different structures are connected by an air-guiding connection and the air pressure in the intermediate layer of the barrier system designed as a floor is higher than in the barrier system designed as a basement and the air enters via the air line into the barrier system designed as a floor at a higher pressure, so that the air flows into the barrier system of low
  • the lower and / or upper inhibiting layer of the basement is covered with a horizontal boundary layer of higher density.
  • a building 2 is shown in the form of a house, which is built on a building ground 1.
  • the temperature Te in the subsoil 1 and the gas pressure pe of the gases contained in the pore volume of the soil are influenced by the outside temperature Ta and the outside air pressure pa. These act on the floor of the building 2. This results in a flow 17a in the ground. If there is not a sufficient barrier system 3 between the building site 1 and building 2, a flow 17b continues in the house. Due to the internal temperature Ti and the internal pressure pi, the gases penetrating into the building 2 through the soil rise upwards and are distributed over the basement 4, the basement 5 and the upper floor 6 throughout the building 2.
  • the device shown in FIGS. 2 and 3 ensures adequate protection against the penetration of gases into the structure 2. At the same time, of course, it also prevents gases from penetrating into the ground, especially through diffusion.
  • the 2 shows a device with a barrier layer. This is arranged in the parting plane between the building ground 1 and the lowest room of the building 2, in the present case the basement 4.
  • the lowest room can also be a living room or another usable room.
  • the barrier layer has a lower layer 9, which is designed as a layer 9 which inhibits the passage of air and gas. In the present case it is the cleanliness layer lying on the building ground 1 and consists of concrete. Furthermore, an upper layer 10, which inhibits the passage of air and gas, is formed, which at the same time forms the floor of the basement 4 above. Between these two Layers 9; 10, an air-guiding intermediate layer 12 is arranged. The air pressure in this intermediate layer 12 is different from the ambient pressure. The air pressure can be greater than the pressure pe in the subsoil 1 and the internal pressure pi in the building 2. But it is also possible that it is less than this and thus forms a vacuum.
  • the latter is connected to a pressure-regulatable air line 13.
  • the pressure regulation is expediently carried out via a pressure or suction fan, which can also be correspondingly adjustable. Ambient air is pressed into the intermediate layer 12 or sucked out of it via this fan (not shown). Since the intermediate layer 12 has a relatively small volume of air, the energy expenditure for ventilation is relatively low.
  • the intermediate layer 12 can have a different structure, which can be designed according to the intended use. This makes it possible to arrange coarse gravel in the intermediate layer, which enables good ventilation.
  • a pipeline 15 can additionally be provided, which is connected to the air line 13 and in which the air exits through openings at various points in the intermediate layer 12 (FIG. 2) .
  • a nonwoven fabric and, in connection therewith, webs 16 made of concrete can be arranged, as is shown in FIG. 3.
  • exhaust air ducts 14 can be provided in the wall, through which the air escapes, especially in the event of overpressure. It is possible to air this lead up into the atmosphere, as shown in Fig. 3.
  • the barrier effect can be increased if several barrier layers are arranged one above the other.
  • a further layer 11 is provided which inhibits the passage of air and gas.
  • These layers 9; 10; 11 then enclose two air-conducting intermediate layers 12 which are separate from one another. Their structure then corresponds to the intermediate layer 12 described in more detail with reference to FIG. 2.
  • the solution according to the invention ensures that the layers 9; 10; 11 inhibit the passage of air and gas, but do not have to completely prevent it. This is also not practically possible, since the floors in older buildings in particular generally have cracks and also become porous. This also occurs in particular because shifts occur in soils in which dangerous gases such as radon are present, which cause stress cracks in the buildings.
  • radon-poor air is largely pressed out of the building or from the open both into the ground and into the basement 4 in the event of air pressure and at low air pressure, radon-rich air is drawn from the ground and low-radon air from the basement 4 into the intermediate layer 12.
  • a physical problem can arise if condensation can form within the layer. This becomes possible if the air flowing into the layer is warmer than the temperature of the adjacent materials and if the air flow is too low to remove condensates. This is avoided if a device for air drying is provided in the air line 13.
  • the solution according to the invention can be provided for buildings to be renovated and for new buildings.
  • the surface to be sealed can also include only parts of a building 2. This is particularly advantageous when a building is being renovated in sections, for example to avoid a temporary move out of residential buildings.
  • the solution according to the invention is also possible for the individual protection of buildings 2, where area-wide measures, such as radon wells, are provided. This provides additional protection.
  • the barrier system 3 in buildings that are used for the storage or interim storage of radioactive materials, hazardous waste or hazardous substances. Gases that form, such as radon or volatile halegonated carbons, can penetrate into the barrier system 3, in particular by diffusion. Such penetration is promoted if the bearing surfaces have leaks. Penetration into the floor is prevented by drainage in the air-bearing intermediate layer.
  • the barrier layers shown in FIGS. 2 and 3 are also well suited for this.
  • Adequate protection is provided against an exchange of gases by convection and / or diffusion between the interior of a building 2 and the building ground 1 when on a horizontal boundary layer 21 is arranged on the upper and / or lower side of the intermediate layer 12.
  • This boundary layer has an increased tightness.
  • a preferred embodiment is their formation from a plastic film. This training is also particularly well suited to protecting against the penetration of dangerous substances into the ground.
  • Fig. 4 the arrangement of the device in a floor with thermal insulation 19 is shown.
  • the barrier layer has a lower layer 9 which is arranged on the building ground and is formed by the sub-concrete 18.
  • the air-guiding intermediate layer 12 is arranged above this layer 9. In the present exemplary embodiment, this is formed in two parts.
  • Thermal insulation 19 is applied to the sub-concrete 18.
  • the actual air duct 25 is arranged above this. It consists of two dense or nearly dense boundary layers 21, which are held at a distance from one another by force-absorbing webs 16, so that the air supplied via the air line 13 (not shown) can flow through it.
  • the air duct 25 Above this air duct 25, the screed 22 of the floor is arranged, which forms the upper layer 10 of the barrier layer, which prevents the passage of air and gas.
  • the wearing layer 23 of the floor is applied to the screed 22 in a manner known per se.
  • the air duct 25 is located as an air-guiding part of the intermediate layer 12 above the thermal insulation 19 inside the building 2.
  • the temperature difference between the temperature in the building 2 and the air flowing through the air duct 25 is therefore less than when the air duct is arranged 25 between thermal insulation 19 and sub-concrete 18. This reduces the risk of condensation. This is particularly advantageous if the air in the intermediate layer 12 has an overpressure.
  • FIG. 5 shows a further example of the arrangement of the device in a floor.
  • the embodiment corresponds essentially to the structure according to FIG. 4.
  • the thermal insulation 19 itself forms the air-guiding layer. This eliminates the need to install an additional air duct 25, as a result of which the construction costs can be reduced.
  • the thermal insulation 19 is encased at the top and bottom to form the suction and pressure space through boundary layers 21.
  • the insulating material itself can also be so dense at the bottom or / and above that it forms the boundary layers 21 from their material.
  • FIG. 6 Another embodiment is shown in FIG. 6. This is particularly suitable for residential buildings.
  • the basic structure corresponds to that described with reference to FIG. 4.
  • the intermediate layer 12 also has an air duct 25 arranged above the thermal insulation 19.
  • a floor heating 24 known per se is installed in this air duct 25, a floor heating 24 known per se is installed. This not only increases living comfort, but at the same time the higher temperature of the floor ensures that no condensation can form.
  • the lower layer 9 and the upper layer 10 have the same structure as described in FIG. 4.
  • An upper wear layer 23 is also arranged here.
  • underfloor heating 24 directly in the thermal insulation 19 if, as in FIG. 5, it forms the air-guiding layer at the same time.
  • the arrangement must be such that the radiation of the underfloor heating 24 into the interior of the building 2 is guaranteed.
  • the air lines 13 for air supply and air discharge into the intermediate layer 12 lie diagonally opposite one another.
  • Guide bars 25 are arranged in the room transversely to the direction of flow of the air between the air lines 13. This makes it possible for the air flowing through to reach all areas of the room evenly, so that "dead corners" in which gas concentrations can form are avoided.
  • These guide webs 26 can be firmly connected to the boundary layers 21, so that they simultaneously fulfill the function of the webs 16 to serve as support elements for ensuring the sufficient strength of the floor.
  • a part of the guide webs 26 serves as supporting elements like the webs 16, while another part exclusively fulfills its function as a guide webs 26.
  • the latter designed as flow barriers, can have a smaller width, are provided with interruptions and can also be connected on one side to the upper or lower boundary layer 21, while on the opposite side there is a slot for the air to flow through.
