    Description Light wells are used to allow light to enter through windows in rooms below the floor level. For this purpose, a light shaft is attached to the building around a window opening and thus guarantees a certain free space in front of the window opening. In order to allow light to enter, such a light shaft has at least one opening on the top, while the other sides, apart from the side intended for contact with the building, are closed in order to prevent the ingress of water and / or moisture. A finishing shaft is retrofitted to the building and fastened there, usually via screw connections. In order to make the light well completely watertight, the contact surface on the building must also be sealed. However, the wall of the building to which the light well is to be mounted is often of an uneven quality. Secure sealing is made considerably more difficult.
    Thermal insulation is common today to insulate buildings thermally and so reduce the energy required to heat the building. The sealing of building openings is of particular importance. If the thermal insulation is inadequate, light wells in particular represent thermal bridges and significantly reduce the energy efficiency of the building. In order to ensure a secure hold of the light well, it is attached to the building structure of the building and not to the comparatively soft thermal insulation. This gives rise to the problem that the light well is very close to the building relative to the surrounding thermal insulation and thus the incidence of light is reduced compared to an otherwise identical arrangement on a non-thermally insulated building.
    It was therefore the object of the present invention to provide a light well that is securely sealed even with different building wall properties and maximizes the incidence of light when there is thermal insulation on the building, in particular in comparison to an otherwise identical arrangement without thermal insulation.
    The object is achieved with a light shaft, in particular a finishing shaft, for mounting on a building opening, with an open side intended for contact with the building and with an opening on the top and with one of the areas intended for contact with the building Open side arranged seal, wherein the seal has an integrated soul. By combining a (plasto) elastic seal with an (elastic) core, i.e. an integrated core, secure tightness is advantageously made possible and guaranteed, since zero compression is avoided and unevenness in the building, in particular the building structure, is compensated for.
    The light well preferably has a U-shaped cross section. The light well particularly preferably has a box-shaped cross section. The light well preferably has four essentially flat parts, and the two side parts are particularly preferably formed symmetrically. As a result, it is advantageously possible to produce the light well according to the invention in a simple, modular and inexpensive manner. However, it is also conceivable for the light well to have other, in particular asymmetrical, shapes and / or cross sections. This advantageously enables the light well to be adapted to the floor and / or building conditions. In particular, the light well is essentially designed with circular segment-shaped or parabolic elements. Such a rounded shape is particularly advantageous statically.
    Preferably, the light well (around a building opening) on a building wall, i.e. attached to a building, alternatively the light well is attached to thermal insulation (so-called perimeter insulation) located on the outer wall of the building.
    Preferably, the light shaft can be screwed to the building, in particular via mounting brackets. The connection is particularly preferably provided by hiding or latching. Through a screw connection, a permanent and stable connection of the light well to the building is advantageously possible without excessive interventions in the building structure of the building. In addition, a screw connection allows the seal to be flexibly adapted to local requirements and / or conditions, since the seal is pressed by the screw connection.
    Preferably, the light well is essentially, in particular except for the seal made of concrete or a concrete-like, stone-like material and particularly preferably made of plastic. The light well is very particularly preferably formed in one piece with the exception of the seal, alternatively the light well is made in several pieces, the individual pieces preferably being connected in a watertight manner. A one-piece construction enables a particularly dense and simple installation of the light well, while a multi-piece construction enables particularly simple manufacture and easy transportation to a destination.
    [0009] The seal is preferably watertight, in particular watertight. The seal is particularly preferably elastically deformable. The seal is very particularly preferably insensitive to temperature, in particular heat and / or cold. In particular, the seal is provided from a butyl rubber. This makes it possible to create a secure seal between the interior of the light well and the surrounding soil (or other material). In particular, tightness is thus advantageously ensured even under changing environmental conditions, such as, for example, frost, excessive heat, rising groundwater or the like. It is beneficial to Butylkau2
    CH 707 463 B1 tschuk to use because it is an inexpensive and proven material with the above properties.
    [0010] The seal preferably has at least partially cavities. This advantageously enables an additional insulating effect.
    [0011] The seal is preferably connected to the light well in a positive, non-positive and / or integral manner. In particular, the seal is connected to the light well by an adhesive connection or by a form-fitting receptacle in a corresponding depression (for example a depression) in the light well.
    This ensures that the seal remains in position relative to the light well during assembly and thus a secure seal is guaranteed.
    Preferably, the integrated core with the surrounding seal is positively, non-positively and / or cohesively connected, particularly preferably the integrated core is cohesively connected to the surrounding sealing material.
    Preferably, the integrated core is provided from a substantially pressure-insensitive material, in particular ethylene-propylene-diene monomer rubber (EPDM). The integrated core particularly preferably has a circular diameter, in particular a diameter of 4 mm to 18 mm, for example 4 mm or 6 mm or 8 mm or 10 mm or 12 mm or 14 mm or 16 mm or 18 mm. While the elastically deformable material of the seal advantageously allows adaptation to the nature of the building, the pressure-insensitive integrated core prevents leakage due to excessive deformation of the seal (to a virtually zero level). EPDM is advantageous as a material for the integrated core, since it has good and long-term resetting behavior and thus permanently ensures the tightness of the connection of the light well to the building. In addition, the compatibility of butyl rubber and EPDM is good and a seal constructed in this way is very resistant to aging. The assembly, preferably the screw connection, deforms the seal and a (pressure) water-resistant double seal with limit stop is achieved. Another advantage of such a seal with an integrated core is that the seal can be checked easily by visual inspection, in particular from the inside and / or from the outside.
    [0015] A coating, in particular a thick bitumen coating, in particular a thick bituminous plastic coating, is preferably provided on the side of the seal. This increases the tightness in a particularly advantageous manner. Butyl rubber and / or EPDM are particularly compatible with bitumen.
    Preferably, between the surfaces intended for bearing against the building and the seal and / or in the assembled state between the seal and the building and / or in the assembled state between the surfaces intended for bearing against the building and the building A spacer is arranged on both sides of the seal.
    Preferably, the spacer is a plastic plate, in particular a plate made of isothermal. This makes it possible in an advantageous manner to avoid a thermal bridge, i.e. to isolate the light shaft from the building thermally and / or to bring the light shaft to the same distance as any thermal insulation of the building and thus to increase the incidence of light while still ensuring tightness. The spacer is particularly preferably water-repellent or water-impermeable. As a result, it is advantageously possible to bridge larger distances without impairing the tightness between the light shaft and the building.
    Furthermore, the object is achieved by a system comprising a light well, preferably a light well as described above, and a preparation means, in particular a special primer, the preparation means being provided for application to the places in the building intended for installation with the light shaft is and wherein the preparation is sealing and configured such that it changes color after application, depending on the nature of the wall, in particular from white to transparent. The color change of the preparation preferably indicates the ability of the system to be installed. This makes it possible in a particularly advantageous manner to check the nature of the building before installation. In this way, any necessary disassembly and reassembly of the system can advantageously be avoided, which would be necessary in the case of non-dense substrates or otherwise a proper connection between the light shaft and building-preventing properties and / or conditions of the building. In addition, such a color change is safe and easily recognizable, especially by non-specialists, which further simplifies assembly.
    The invention is explained below with reference to FIGS. 1 to 4. These explanations are only examples and do not limit the general idea of the invention.

    In Fig. 1, a light well according to the invention according to a first exemplary embodiment is shown in a schematic detailed view. A light shaft side wall 1 intended for contact with a building 2 or a building wall 2 is shown on the left. Alternatively, the light well according to the invention can also be mounted on thermal insulation of a building. The building comprises a building opening, usually a window opening, shown here as a window pane 5. There is a seal on the end face of the light shaft side wall 1 intended for bearing against the building wall 2, but also on the other surfaces of the light shaft intended for bearing against the building wall 2 3 arranged, the seal 3 has an integrated core 4. This integrated core 4 is shown here as a tubular element with an approximately circular cross section. The integrated core 4 is made of EPDM and enclosed by butyl rubber. The integrated core 4 is integrally connected to the butyl rubber. The seal 3 here has an essentially elliptical cross section, but it can also take any other form known to the person skilled in the art, for example a band-like cross section or a circular cross section, or an irregularly shaped cross section, in particular with sealing lips on both sides of the integrated core 4 the installation, the sealing material will usually completely enclose the integrated core 4. During installation, the light shaft is brought into contact with the building wall 2 and preferably screwed to it. The resulting contact pressure causes the seal 3 (elastic) to be deformed and its cross section is reduced in the direction perpendicular to the building wall 2. The integrated core 4 is not or only slightly deformed, in particular reduced in cross section. As a result, even at high contact pressure or a comparatively high unevenness of the building wall 2, the seal is never deformed in such a way that the light shaft side wall 1 has approximately direct contact with the building wall 2, but there is always a minimum distance between the building wall 2 and the light shaft side wall 1 The cross-sectional length of the integrated core 4 in the direction perpendicular to the building wall 2 is retained, which enables a tightness between the light shaft and the building. During and after the installation of the light well, the correct fit and thus the correct functionality of the seal 3 can be checked visually, both from inside the light well and from the outside.
    In Fig. 2, a light well according to the invention is shown according to a second exemplary embodiment in a schematic detailed view. The second embodiment essentially corresponds to the first embodiment, the difference being that a bitumen thick coating 6 is arranged on the side of the seal 3, in particular on both sides, or alternatively only on one side. According to a further embodiment, not shown, it is flexibly adapted to the shape of the seal 3 and / or is flush with the light shaft side wall 1.
    In Fig. 3, a light well according to the invention according to a third exemplary embodiment is shown in a schematic detailed view. The third embodiment essentially corresponds to the first embodiment, the difference being that a spacer 7 is arranged between the light shaft side wall 1 and the seal 3. The spacer 7 here is a high-strength plastic plate, in particular made of isothermal. The spacer 7 has an essentially rectangular cross section, the extension in the direction perpendicular to the building wall 2 preferably being greater than the extension parallel to the building wall 2. The spacer 7 is watertight, in particular watertight and not elastically deformable. As a result, it ensures a greater distance between the light shaft and the building, as a result of which the incidence of light through the window 5 is increased in comparison to the otherwise identical arrangement without spacing means 7.
    4 shows a light well according to the invention in accordance with a fourth exemplary embodiment in a schematic detailed view. The fourth embodiment essentially corresponds to the third embodiment, the difference being that the spacing means 7 is arranged between the seal 3 and the building wall 2. If, for example, thermal insulation is arranged on the building, the spacing means is flush with the thermal insulation, is firmly connected to the building wall and the light well together with the seal is arranged flush at the level of the thermal insulation.
    5 shows a light well according to the invention according to a fifth exemplary embodiment in a schematic detailed view. The fifth embodiment essentially corresponds to the first embodiment, with the difference that a spacing means 7, 7 'is arranged on each side of the seal 3. The spacing means 7, 7 'are preferably essentially identical in terms of their shape and dimensions, but alternatively the outer spacing means T has a greater thickness than the inner spacing means 7. The spacing means 7, 7' additionally protect the light well eintre4
    CH 707 463 B1 tending water and ensure an even distance from the building wall 2, whereby an excessive application of force to the seal 3, corresponding to excessive deformation, is avoided.
    6 shows a light well according to the invention in accordance with a sixth exemplary embodiment in a schematic detailed view. The sixth embodiment essentially corresponds to the fifth embodiment, with the difference that a spacing means 7 is arranged only on the outward-facing side of the seal 3. While in the other embodiments the seal 3 is arranged essentially in the middle of the end face of the light well side wall 1, the seal 3, i.e. the center of the cross-section of the seal 3, according to the sixth embodiment, preferably arranged further inside, but of course the seal can still be arranged essentially in the center according to further not shown embodiments. Such a combination of spacing means 7 and seal 3 makes it possible to combine the advantages of both elements. The light well is redundantly watertight, a minimum distance between the building wall 2 and the light well side wall 1 is guaranteed and the correct seating of the seal 3 can still be checked from the inside by visual inspection.
