In this installation element may be any component which is provided in a recess in a wall or in a bottom plate. Preferably, however, the installation element is a tubular installation element, but particularly preferably a frame, in particular a window frame.

"Flange-like" in the sense of the present invention means in particular that the thickness of the flange is smaller than the thickness of the component on which it is provided, so that the heat insulation is indeed around extends the entire circumference of the component, but this does not completely cover

Thermal insulation has a thickness of 6 - 20, more preferably 6 - 10 cm. Thermal insulation reduces heat losses in the direction of the environment, in particular into the soil. In particular, it is a thermal insulation of a heat insulating rigid foam material. Preferably, this rigid foam material is extruded polystyrene foam marketed under the trade name Styrodur. The average specific gravity of the material of the thermal insulation is advantageously less than 0.2 g / cm ³ , in particular less than 0.1 g / cm ³ . The rigid foam is particularly preferably poly-urethane foam (PUR foam).

CONFIRMATION COPY Preferably, the thermal insulation is connected to the mounting element, in particular materially connected. Preferably, the mounting element with the

Envelopes foamed heat insulation material, so that the flange-like heat insulation results, which during foaming a cohesive bond between the

Thermal insulation and the installation element results. In order to improve this material connection, the installation element may have appropriate means. For example, the

Roughen surface of the mounting element.

Preferably, an anchoring means is provided on the heat insulation, which forms a material, positive and / or non-positive connection with hardening concrete.

Preferably, at least one, preferably two or more anchoring means are respectively provided to the right and left of the mounting element. These anchoring means are also material, positive and / or non-positively connected to the thermal insulation and are particularly preferably from the inner surface out. after the

Heat insulation has been poured with concrete, and this concrete is cured, comparatively high loads, such as a concrete light shaft can be mounted directly on the heat insulation, without fear that the bond between the thermal insulation and the concrete dissolves. Preferably, a rail or the like is provided in or on the thermal insulation, which can accommodate a plurality of anchoring means. The number of anchoring means can then be variably provided, for example, in terms of number and location per rail.

Preferably, in each case one rail is arranged in particular vertically to the right and left of the recess. The rail is positively and / or cohesively with the

Thermal insulation connected. The anchoring means are connected to the rail.

The installation element according to the invention preferably has one or more

Another object of the present invention is a device with the

installation element according to the invention, wherein on the front side of the heat insulation is a connection heat insulation provide. Preferably, the heat insulation and the connection heat insulation each have on its inner surface a sealing means which are sealingly connected to each other, wherein subsequent to the sealant, a concrete / stone layer is provided, which enters into a Kriechwasserfeste compound with the sealant.

The connection heat insulation can be made of a water-repellent or a

be made of waterproof material.

In the component according to the invention, the thermal insulation of the installation element is surrounded by a connection heat insulation. In this case, the heat insulation of the installation element and the connection heat insulation are at least partially,

preferably completely in the same vertical plane, d. H. the connection heat insulation is arranged on the front side of the heat insulation of the installation element and preferably has the same thickness. In the present case, both the

Heat insulation of the mounting element, as well as the connection heat insulation each at its inner surface a sealing means, as described above, which, after the elements have been placed side by side, are joined together. This connection is preferably carried out with a sealing strip and / or in that the respective sealing means overlap at least partially. Subsequently, this sealant is brought into contact with a liquid concrete / stone layer, which forms a creep waterproof connection after curing of the concrete with the sealant. Preferably, the connection between the thermal insulation and the sealant is also watertight.

Installation element placed in a formwork, which is then filled with concrete, especially with water-impermeable concrete. That is, this concrete surrounds directly or indirectly both a surface of the thermal insulation, as well as their front side and cures there. During curing, a preferably present anchor element is firmly connected to the concrete, so that subsequent to the heat insulation a heavy

Connection elements, such as a light well, can be arranged without the connection between the heat insulation and the concrete layer dissolves.

Thermal insulation, which is provided flange on the mounting element according to the invention or preferably overlaps. As a result, thermal bridges are avoided. Preferably, these heat insulation are directly adjacent to each other or are at most by a

Sealant separated.

The statements made to the installation element according to the invention apply equally to the components according to the invention and vice versa.

Another object of the present invention is a device having an outer heat insulating layer and a concrete / stone layer, wherein between the heat insulating layer and the concrete / stone layer, a sealing means is provided and the component has a recess into which a mounting element is used, wherein the mounting member has a flange which bears against the sealing means.

The component according to the invention can be, for example, a wall element, a ceiling element and / or a base plate.

According to the invention, the component has a heat insulation layer which reduces heat losses of the component in the direction of the environment, in particular into the ground. In particular, it is a thermal insulation layer of a thermally insulating rigid foam material. Preferably, this hard foam material extruded polystyrene foam marketed under the trade name Styrodur. The average specific gravity of the thermal insulation material is advantageously less than 0.2 grams per cm ^{3, more} preferably less than 0.1 grams per cm ³ .

Furthermore, the device according to the invention has a concrete / stone layer. This concrete / stone layer can be erected on the construction site or the entire component according to the invention is prefabricated delivered to the site. The stones are preferably gas concrete blocks.

According to the invention, a flat sealant is provided between the thermal insulation layer and the concrete / stone layer, which prevents the water from entering the structural element and thus from building to be erected. This sealant can be applied to the outer formwork member by casting, brushing, spraying, and the like. However, it can also be connected as a geomembrane to the outer formwork element. Preferably, the sealing element at least partially on bitumen, so that it is strongly adhesive. The sealant forms with the fresh concrete to be cast or with a stone layer a very intimate cohesive and Kriechwasserdichte compound. With the fastener according to the invention is now prevented that this compound is at least partially dissolved during the casting of the ceiling and thus in particular the sealing effect is reduced.

A geomembrane according to the present invention is in each case a planar, preferably flexible, particularly preferred waterproof carrier, in particular a plastic film which is provided with a sealing material at least on its side facing the concrete / stone layer, which is to be hardened with fresh concrete and / or with a stone layer forms a creep-water-tight interface, as known for example from EP 796 951 B1.

Furthermore, according to the invention, there is a recess in the component which penetrates the heat insulation layer, the sealant and the concrete / stone layer. In this recess, a built-in element, for example, a pipe, eg for the waste water supply and waste water discharge, a gas line, a conduit, a cable, a window, a door or the like, are arranged. The mounting element can be made of any material or any combination of materials. Preferably, however, the mounting element is at least partially made of plastic. According to the invention, the mounting element has a flange which surrounds the mounting element on its entire circumference and which is either waterproof, in particular materially connected to the mounting element or is provided integrally with the mounting element. This flange is now provided on the mounting element, that it rests after the installation of the mounting element in the component, preferably with one of its two end faces, on the sealing means and thereby cooperating sealingly with the sealing means. This prevents water entering through the recess from getting between the thermal insulation layer and the concrete / stone layer.

The component according to the invention is preferably created by providing the heat insulation layer with the sealing means provided on one side of the surface. In the heat insulation layer and the sealant is then or the recess is already provided, in which then the installation element is used. When inserting and / or after the subsequent creation of the concrete / stone layer then the flange of the mounting element is applied to the sealing layer and ensures a watertight connection.

Preferably, the voltage applied to the surface of the flange of the flange materially connects to the sealant.

Preferably, the flange is biased against the sealant. This bias is preferably generated by the concrete / stone layer pressing the flange against the sealant.

In a preferred embodiment of the present invention, the flange is provided flexibly. As a result, unevenness in the thermal insulation layer and / or in the sealant can be compensated for and / or the flange can be better pressed against the sealant by the concrete / stone layer.

Another object of the present invention is a mounting element which is arranged in a wall or a floor plate of a building and which has a flange which can be brought into abutment with a sealing means of the wall or a bottom plate.

Preferably, the flange is provided flexibly. The inventions will be explained below with reference to FIGS. 1 to 7. These

Explanations are merely exemplary and limit the general

Inventive idea not one. The explanations apply equally to all inventive articles of the present invention.

FIG. 1 shows an embodiment of the installation element according to the invention.

Figure 2 shows details of the anchoring and fastening means on the

installation element according to the invention.

FIG. 3 shows a first embodiment of the component according to the invention.

FIG. 4 shows another embodiment of the component according to the invention.

Figures 5a and 5b show the installation element according to the invention with an attachment element, here a light shaft.

FIG. 6 shows a further embodiment of the component according to the invention. FIG. 7 shows yet another embodiment of the component according to the invention.

FIG. 1 shows the installation elements 1 according to the invention, in the present case a basement window which has a frame 2 and a window pane 3. On the outer circumference of the frame 2, a flange-like heat insulation 4 is provided, which is in particular integrally connected to the frame. In the present case, the thermal insulation is a hard foam, with which the frame 2 has been foamed. It can be clearly seen that the thickness of the thermal insulation is less than the thickness of the frame. The thickness of the heat-insulating flange is comparatively small compared to its extension in a plane provided perpendicular thereto. Preferably, the thermal insulation ends flush with one end of the frame or the component to be installed in a wall. Preferably, the heat insulation on its inner

Surface 4.5, especially preferred on the entire inner surface 4.5 a

Sealant 4.1, which enters into the thermal insulation, preferably a cohesive, particularly preferably Kriechwasserdichte connection. Also preferably, the heat insulation on its inner surface at least one, preferably at least two, anchoring means 6, which is provided on the right and left of the element to be installed, here the basement window, and those with concrete, with the inner surface of the 4.5 Heat insulation is poured behind, after its curing, form a solid connection, so that even at a high load, the thermal insulation 4 does not dissolve from the concrete layer 10. FIG. 2 shows details of the thermal insulation 4 according to FIG. 1. As already mentioned, this preferably has a sealing means 4 on its inner surface 4. 4, which prevents water from penetrating into the building. In a preferred embodiment, this agent also partially extends into the boundary layer between the thermal insulation 4 and the window frame 2. Furthermore, it can be seen from the representation according to FIG. 2 that the anchoring means 6 preferably has at least one, preferably a plurality of anchoring means 6.1, which are enclosed by the fresh concrete at their circumference. Furthermore, the anchoring means 6 preferably has a flange 6.2, which preferably presses against the sealant 4.1. In the present case, the heat insulation, a fastening means 7, for example a sleeve, which is preferably foamed into the heat insulation and a fastening means 7.1 for the

An anchoring means, here for example a threaded hole, and having on its opposite side a fastening means 7.2 for a mounting element 11,

for example, also has a threaded hole. Preferably, there is a distance between the two means 7.1 and 7.2, so that no cold bridges can arise.

FIG. 3 shows a first embodiment of the component according to the invention. In the present case closes at both end face 4.2 of the thermal insulation 4 a

Connection heat insulation 9 flush, which are arranged in a common vertical plane and preferably each having the same thickness. Both insulation 4, 9 have on their inner side in each case the sealing means 4.1, 9.1 described above, which preferably forms a plane substantially. To prevent creeping water in the gap between the heat insulation 4 of the mounting element 1 and the

Connection heat insulation 9 passes, this is sealed, preferably covered with a sealing strip 8 before the sealant 4.1, 9.1 are back-filled with fresh concrete 10. During curing, the concrete preferably forms a creep-tight connection with the sealant. Furthermore, the anchoring means 6 form and

non-positively connected possibly also cohesively with the concrete 10. Thereby, on the outer surface 4.4 of the thermal insulation 4 of the mounting element 1, a comparatively heavy attachment element 11, for example, a light shaft made of concrete, be arranged without the connection between the heat insulation 4 and the sealant 4.1, or between the sealant 4.1 and the Concrete 10 releases. The person skilled in the art will understand that, alternatively or additionally, an anchoring element can be provided on the connection heat insulation 9 and / or that the attachment element can alternatively or additionally be connected to the connection heat insulation.

FIG. 4 shows another embodiment of the component 5 according to the invention. In the present case, the component has no terminal insulation, which adjoins the End 4.2 of the insulation 4 connects, but this connection insulation is provided with the outer surface 4.4 of the insulation 4 overlapping. As a result, fresh concrete 10, with which the thermal insulation 4 is poured behind, surrounds the thermal insulation 4 on its inner surface 4.5 and on the end face 4.2. By the anchoring means 6 in turn creates an intimate bond between the heat insulation 4 and the concrete 10, so that a heavy attachment element 11, for example, a light shaft made of concrete, can be arranged on the insulation, without the bond between the

Thermal insulation 4 and the concrete 10 separates. The terminal insulation 9 is arranged here on the outer side of the concrete layer 10 and that the shape that it overlaps the insulation 4 at least partially. As a result, there is no thermal bridge. The concrete 10 can be made in the present case as water-impermeable concrete. However, it is also possible to provide a sealing layer, for example as described above. The person skilled in the art will understand that, alternatively or additionally, an anchoring element 6 can be provided on the connection heat insulation 9 and / or that the attachment element can alternatively or additionally be connected to the connection heat insulation.

Figures 5a and 5b show an inventive installation element 1, here a window frame with a window. Clearly visible here are four anchoring elements 6, each having anchor means 6.1, here arranged V-shaped anchor means 6.1 and a flange 6.2 which against a seal, on the entire inner surface of the

Heat insulation is provided, presses. On the opposite side are

Fixing means 7.2, for example holes with a thread, indicated, with which a mounting element 11, here a light shaft can be attached to the heat insulation 4. The anchor means 6.1 are encapsulated with concrete, so that after curing forms a very intimate bond between the heat insulation 4 and the concrete layer, which can not be solved by a comparatively heavy component 11.

FIG. 6 shows a component 1 which has a heat insulation layer 2. The outer side 2.1 of the thermal insulation layer is exposed to environmental influences, in particular moisture. Furthermore, the component according to the invention has a concrete or stone layer 4. Between the concrete or stone layer 4 of the component, a planar sealing means 3 is provided, which covers the entire interface between the thermal insulation layer and the concrete / stone layer. Furthermore, the component according to the invention has a recess 6 which extends through the heat insulation layer 2, the flat sealing means 3 and the concrete or stone layer 4. In this recess 6 a pipe, for example, a fresh water, sewage or empty pipe is provided in the present case, which has a flange 5.1 at its outer periphery. This flange 5.1 can be watertight connected to the cylindrical part of the tube or in one piece be provided. In the axial direction of the flange 5.1 is arranged so that it rests against the sealing means 3, when the end face of the tube is in the region of the outer side 2.1 of the component, is preferably flush therewith or beyond. Preferably, the flange 5.1 is provided flexibly and very particularly preferably the flange 5.1 is pressed by the concrete / stone layer 4 against the sealing means 3. The component according to the invention can preferably be produced by providing the heat insulation layer 2 with a recess 6 into which the installation element 5, in this case the tube, is pushed so far that the flange 5.1 bears against the sealant 3. Then, the concrete or stone layer 4 is erected by, for example, pouring concrete onto the sealant layer 3. By the concrete layer 4, the flange 5.1 is pressed against the sealant 3, so that there is a particularly intimate and Kriechwasserdichter preferably cohesive bond between the flange 5.1 and the sealant 3. When the concrete hardens, a cohesive water-tight connection is formed between the sealant layer 3 and the concrete 4.

FIG. 7 essentially shows the component according to FIG. 1, so that reference is made to the statements made there. Instead of the tube, a window with a frame 5.2 is inserted into the recess 6 in the embodiment of Figure 2. On this frame, a flange 5.1 is also waterproof arranged along its entire circumference, which enters into a kreichwasserdichten composite with the sealant 3. The flange 5.1 is arranged in the axial direction so that the window has the desired installation depth in the wall.
