Description

[0001] The present invention relates to a wall module, in particular an element of a house wall basement wall or similar elements of a house wall.

[0002] Within the scope of this invention, the term "insulating device" encompasses all types of insulating devices, such as sound-insulating devices or thermal insulation devices. Connecting elements can also be of any kind, such as adhesives of all kinds, adhesive tapes, sealing tapes, or other means capable of creating a watertight connection between two elements.

[0003] It is common practice to install light wells on house walls to allow basement windows to enter the underground part of the house. A problem that arises is that the light wells and windows must be securely connected to the house wall to withstand water pressure due to standing groundwater, heavy rain, or flooding. Furthermore, it is desirable to avoid thermal bridges when installing a basement window, as these can lead to condensation on the window frame.

[0004] As described in DE 20 2011 000 637 U1 and in the ACO Therm® Block brochure with integrated window frame or recess for standard and watertight installation (01 / 2011), it is common practice to attach an insulation unit around the window opening to the completed house wall. This insulation unit is then bonded to the house wall in a watertight manner. The perimeter insulation typically used in the underground parts of a house can then be installed around this insulation unit. A light well, usually made of plastic or concrete, can then be attached to the insulation unit in a watertight manner. All of these steps normally take place on the construction site, making it complex to coordinate the various trades involved.It has become apparent that on construction sites, it often happens that light wells are initially installed watertight in the area around the windows and directly onto the concrete basement wall. A watertight installation of light wells directly onto the perimeter insulation is not possible. After the light wells are installed, the perimeter insulation is then laboriously applied in and around the light well.

[0005] In the next phase, perimeter insulation is installed around the entire house wall. This is usually secured with a bitumen coating, for example. This leads to significant additional costs and a longer construction time.

[0006] A house wall consisting of several prefabricated wall elements is known from DE 10 2004 040 201 A1. In this design, a core concrete layer is poured on-site between an inner shell and an outer shell made of insulating material. DE 10 2004 040 201 A1 discloses the features of the preamble of claim 1. Furthermore, certain materials cannot be processed under all weather conditions, which in turn can delay construction and thus quickly increase overall costs.

[0007] The invention is therefore based on the objective of providing a wall module of the type mentioned above that can be fully assembled outside the construction site.

[0008] This task is accomplished by the wall module according to claim 1.

[0009] According to the invention, the problem is solved by a wall module which includes, among other things, the following features - a concrete wall, in particular a basement wall, with an outside and an inside, wherein the concrete wall forms at least one first passage, in particular a basement window opening, from the inside to the outside; - an insulating device arranged on the outside, which defines a second passage that is at least partially aligned with the first passage; - at least one first connecting element for a pressure-resistant connection of the insulation device to the wall, wherein the first connecting element is arranged between the insulation device and the concrete wall, and the first connecting element forms a fresh concrete bond between the concrete wall and the insulation device during the production of the concrete wall.

[0010] A complete wall module is provided, with the first connecting element forming a bond between the concrete wall and the insulation system within the fresh concrete. This has the advantage that the insulation system is attached to the concrete while it is still fresh, and especially while it is still damp. This allows steps that are very complex on the construction site to be carried out easily in a factory under controlled conditions. This saves both time and money.

[0011] According to the invention, the insulation device has a first flange which rests flat against the outside of the concrete wall.

[0012] Such a first flange on the insulation device has the advantage that the surface area of ​​the insulation device is increased beyond the area of ​​the insulating effect. The surface area of ​​the insulation device is comprised of the area of ​​the insulating effect and the surface area of ​​the surrounding flange. This ensures that no water can penetrate between the insulation device and the concrete wall.

[0013] According to the invention, the wall module has a window frame, wherein the window frame is arranged in the first passage or in the second passage and, wherein the window frame has a second flange, wherein the second flange is connected to the concrete wall via at least one second connecting element, wherein the second connecting element forms a fresh concrete bond between the concrete wall and the second flange.

[0014] According to the invention, a window frame is arranged in the opening of the concrete wall or in the opening of the insulation system. Subsequent installation on the construction site or plastering of the reveal is then unnecessary. The window frame can also have a second flange that rests on the concrete wall in such a way that a second connecting element creates a bond between the second flange and the concrete wall. Thus, the window frame is also installed in a way that protects against pressurized water, providing increased protection against water ingress into the basement of a building.

[0015] Preferably, the wall module can have a protective device arranged on the outside of the concrete wall around the insulation device.

[0016] In addition to the insulation, a protective device, particularly perimeter insulation, can be attached to the concrete wall at an early stage. This involves carrying out another work step off-site, leading to similar advantages as described above.

[0017] Preferably, the concrete wall can be either a double-shell or a monolithic concrete wall.

[0018] A variety of construction methods are used for exterior walls in buildings. A monolithic concrete wall has the advantage of being very easy to construct. A double-shell concrete wall has the advantage of creating an additional thermal and moisture barrier.

[0019] Preferably, the wall module can have a reveal element that is arranged on the said window frame, wherein the reveal element is connected to the window frame, in particular glued.

[0020] When a reveal element is installed on the window frame, the window frame can be positioned in the first opening to achieve optimal thermal insulation without thermal bridges. The reveal element can extend through the entire second opening, thus providing a neat appearance. Furthermore, the connection between the reveal element and the frame can be adhesive. If a watertight adhesive bond is chosen between the reveal element and the frame, an additional sealing layer is provided. This ensures optimal protection against water ingress into the interior of a basement.

[0021] The following method for manufacturing the wall module, in particular a wall module as described above, is proposed. - Inserting an insulation device into a formwork or vibrating table; - Fixing the insulation device using fixing means, in particular using magnets; - Laying a protective device around the insulation device; - Applying at least one first bonding agent to the insulation device; - Pouring fresh concrete into the formwork or vibrating table so that the first bonding agent and the second bonding agent create a bond between the fresh concrete and the insulation device. - and thus forms a fresh concrete bond between the fresh concrete and the window frame.

[0022] In addition to the advantages already mentioned in connection with the wall module, it is further beneficial that the wall module can be produced in a formwork or vibrating table. Formwork tables are standard components in concrete plants, and therefore the process does not require any expensive new equipment. Another advantage is that, with the described method, all elements are already in place before the concrete dries, so a finished wall module is ready when the concrete is dry. Work on the next wall module can therefore begin while the current one is drying.

[0023] It is even possible to provide a wall module including the light well. This eliminates a further step that would otherwise have to be carried out on the construction site. This in turn saves costs and time and simplifies quality assurance.

[0024] Preferred embodiments of the invention will become apparent from the following description of exemplary embodiments, which are explained with reference to the figures. These show Fig. 1 an exploded view of the wall module in one embodiment in a side front view; and Fig. 2 an exploded view of the wall module in the embodiment in a side rear view; Fig. 3 a profile view of a window frame.

[0025] In the following, the same reference numbers are used for identical and equivalent components.

[0026] Fig. Figure 1 shows an exploded view of an embodiment of the wall module 1. Here, an insulating device 20 is attached to an outer surface 12 of a concrete wall 11, around a window opening 14. A protective device 30 is arranged around the insulating device 20. The insulating device 20 provides thermal insulation in the area of ​​the window opening 14 of the concrete wall 11. This is advantageous because thermal bridges can easily occur in this area. Condensation can then form, especially on windows. The protective device 30, on the other hand, protects the concrete wall 11 from the soil, which would otherwise come into direct contact with the concrete wall 11 in the case of basement walls.

[0027] The Fig. Figure 2 shows that a first connecting element 2 is arranged between the concrete wall 11 and the insulation device 20. This element is preferably a sealing tape that is applied to the still-damp concrete of the concrete wall 11, thus creating a fresh concrete bond between the insulation device 20 and the concrete wall 11. The connection between the concrete wall 11 and the insulation device 20 prevents the ingress of pressurized water. The connection via the first connecting element 2 therefore constitutes a first sealing layer.

[0028] The protective device 30 is a perimeter insulation system, typically located underground on a house wall. It protects the house wall from direct contact with the soil and provides thermal insulation.

[0029] Preferably, a window frame 40 is arranged in the plane of the insulation device 20 in a passage 21. The window frame 40 is connected to the concrete wall 11 in a watertight manner.

[0030] Furthermore, it shows Fig. 2. A reveal element 44 is arranged on the window frame 40 and projects through the opening 14 in the concrete wall 11. The reveal element 44 is connected to the window frame 40, in particular by bonding, so that a watertight connection, i.e., an additional sealing layer, is present. Furthermore, the reveal element 44 ensures that the concrete wall 11 has an aesthetically pleasing finish for the user.

[0031] Fig. Figure 1 shows an exploded view of a wall module 1 in an embodiment, in a side front view. In particular, it shows Fig. 1. The protective device 30 itself can consist of many individual elements, e.g., closed-cell foam panels. In this embodiment, the insulating device 20 has a first flange 22, which is arranged between the concrete wall 11 and the protective device 30.

[0032] The first flange 22 of the insulation device 20 is connected to the concrete wall 11 via a first connector 2. The first connector 2 forms a fresh concrete connection between the insulation device 20, namely the first flange 22 of the insulation device 20, and the concrete wall 11.

[0033] Furthermore, it shows Fig. 1, that a window frame 40 is arranged in the plane of the insulation device 20.

[0034] Fig. Figure 4 is a side rear view of the same embodiment as that of the Fig. 1. Fig. Figure 2 shows that a second flange 41 is arranged on the rear side of the window frame 40. The second flange 41 of the window frame 40 is connected to the concrete wall 11 via a second connector 42. The second connector 42 establishes a fresh concrete connection between the second flange 41 of the window frame 40 and the concrete wall 11. Furthermore, the fresh concrete connection between the second flange 41 and the concrete wall 11 provides an additional sealing layer that protects against water ingress.

[0035] Fig. Figure 2 further clearly shows that the first connecting element 2, which is used to connect the insulation device 20 to the concrete wall 11, is only attached in the area of ​​the first flange 22 of the insulation device 20.

[0036] In the embodiment of the Fig. 2 A reveal element 44 is arranged on the window frame 40, which projects through the opening 14 defined by the concrete wall 11 to the inside 13 of the concrete wall 11. This reveal element 44 is bonded to the window frame 40 in a watertight manner, thus forming an additional sealing layer.

[0037] The Fig. 1 and Fig. Figure 2 also shows that the concrete wall 11 can be designed as a double shell.

[0038] The second flange 41 of the window frame 40 is arranged between the insulation device 20 and the concrete wall 11. The second flange 41 is clearly in Fig.Figure 3 shows that in one embodiment, the second flange 41 is bonded to the window frame 40 in a watertight manner. A second fastener 42 is attached to the second flange 41 of the window frame 40 in such a way that a fresh concrete bond is formed between the second flange 41 of the window frame 40 and the concrete wall 11. The second fastener 42 then forms a further sealing layer that protects against water ingress.

[0039] The first and second connecting agents 2, 42 can of course also be the same type of connecting agent, e.g. a specific adhesive or a specific sealing tape, e.g. SikaProof Tape or an equivalent.
