    description
    COMPONENT
    The invention relates to a component with a frame for receiving a window or door frame, the frame, which can be installed in a building wall, consists of a load-bearing insulating material through and through and on its outer peripheral surfaces for a firm connection to the adjacent Areas of the building wall is prepared.
    A component of this type is known from DE 20 2018 003 132 U1. In this known arrangement, the outer peripheral surfaces of the frame are provided with a coating consisting of a material that binds with the adjacent building material of the building wall, preferably sand, in order to achieve a reliable connection to the surrounding building material and thus good integration into the building wall. However, the production of the coating proves to be comparatively complicated and expensive.
    On this basis, it is therefore the object of the present invention to improve a component of the type mentioned in such a way that a comparatively simple and inexpensive production is possible.
    This object is achieved in that in a component of the type mentioned above, the outer peripheral surfaces of the frame have an at least partially open-pored, absorbent structure.
    The porous, absorbent surface structure ensures that the building material used to form the building wall, in the form of a commonly used concrete slurry, can get into the near-surface areas of the outer peripheral surfaces of the frame used in the formwork when the building wall is poured, so that a reliable, internal micro-serration and thus a good connection. A coating with sand etc. can advantageously be omitted here.
    [0006] Advantageous refinements and expedient developments of the higher-level measures are specified in the dependent claims. Thus, in the case of a frame consisting of a hard foam, such as PUR hard foam, which has a smooth surface per se, the desired surface structure can be obtained simply by roughening the outer peripheral surfaces. The roughening of the surface damages the pores of a closed-pore rigid foam at least partially in such a way that the desired open-pore, absorbent structure results. It is therefore advantageously possible to use a closed-cell, surface-compacted hard foam with the desired good load-bearing capacity to form the frame and still achieve the desired good connection to the surrounding building material of the wall.
    A further supporting measure can be that in the area of the outer peripheral surfaces of the frame over its length and/or width distributed, radially outwardly open, preferably radially inwardly widening peripheral grooves are provided. These lead to a form-fitting macro-interlocking with the surrounding building material that supports the aforementioned micro-interlocking, and thus to a particularly reliable connection.
    In a further development of the higher-level measures, it can be provided that the frame, the width of which corresponds to the thickness of the building wall without thermal insulation provided on the outside, has an insulating frame made of a pressure-resistant insulating material on the outside of the housing with the thickness of the thermal insulation adjoining it on the side corresponding thickness is upstream, which has in the area next to the frame on both sides in each case at least one integrated into the building wall holding member, preferably in the form of a threaded sleeve, associated hole. These measures allow a simple attachment of components that can be hung on the building wall, for example a light well assigned to a basement window. Simultaneously or alternatively, a reliable fastening of the insulating frame can also be achieved in this way.
    A further advantageous measure can consist in that an insulating frame consisting of a similar or the same insulating material as the frame and extending to the outside of the building rests against the edge region of the frame projecting towards the outside of the building in relation to the window or door frame. In this way, thermal bridges can be reliably avoided, particularly in conjunction with the neighboring insulation frame.
    The frame can expediently be provided on the front side with a circumferential seal in each case. The front seals advantageously allow the frame used in a formwork for casting the building wall to be sealed off from the formwork, so that the building material used for casting the building wall cannot crawl past the frame installed in the formwork.
    Further advantageous refinements and expedient developments of the higher-level measures are specified in the remaining subclaims and can be inferred from the example description below in connection with the claims.
    In the drawing described below:
    Figure 1 is a partial view of a basement wall with a built-in component containing a basement window and
    [0014] FIG. 2 shows a horizontal section through a side area of the arrangement according to FIG.
    1 shows a section of a building wall 1 in the form of a basement wall, in which a component 3 associated with a building opening 2 in the form of a window or a door is installed. A building wall of the type present here usually consists of concrete, which is poured into a formwork into which the component 3 is already inserted, so that it is poured into the building wall when it is poured. The component 3 designed as a prefabricated component contains an outer frame 4, in which a window or door frame 5 assigned to a window or a door is already accommodated. On the outside of the building wall 1 made of concrete, etc., as can be seen from FIG. The width of the frame 4 corresponds to the width of the building wall 1 without the outer thermal insulation 6. In simple cases, the thermal insulation can cover the end face of the frame 4 pointing to the outside of the building.
    The frame 4 consists thoroughly of a sufficiently stable insulating material, which is advantageous for avoiding thermal bridges. A rigid foam, preferably a PUR rigid foam, can expediently be used to form the frame 4 . A foam material with a density of 0.40 to 0.50 g/cm*®* and a compressive strength of at least 3 and preferably 3.5 N/m* has proven to be particularly useful. With such a foam material, a maximum heat transfer coefficient of 2.0 to 2.2 W/m°K can be achieved, which reliably prevents the formation of thermal bridges.
    The frame 4 is in the creation of the building wall 1, which is usually made of concrete in the case of a basement wall, as already mentioned, concreted into this. In order to achieve a firm connection of the frame 4 with the surrounding building material of the building wall 1, the radially outer surfaces of the frame 4 have an at least partially open-pored, absorbent structure into which the concrete slurry used for casting the building wall 1 can penetrate, so that in the hardened state, a micro-serration of the outer sides 7 of the frame 4 results with the surrounding building material. A rigid foam of the above-mentioned type used to form the frame 4 is usually a closed-pore rigid foam with a smooth surface. In order to achieve the desired open-pored, absorbent structure here, the radially outward-facing surface of the frame 4 is roughened accordingly. For this purpose, a thin layer close to the surface can be machined from the foam on which the frame 4 is based, e.g. B. by milling, which injures a sufficient number of pores and thus a partially open-pored, absorbent structure is achieved. Said roughening of the foam on which the frame 4 is based can be expedient
    be made before the creation of the frame 4 and are thus available practically from the beginning.
    In the example shown, the frame 4, as can be clearly seen from FIG. 2, is provided in the region of its roughened outer sides 7 with circumferential grooves 8 which are distributed over its length and/or width and are open radially outward. These result in macro-interlocking of the frame 4 with the surrounding building material of the building wall 1 in addition to the above-mentioned micro-interlocking.
    As already mentioned, the frame 4 is concreted into the building wall 1 when it is made and is installed in the formwork created for the production of the building wall 1 before casting. In order to prevent the concrete slurry coming into contact with the frame 4 installed in the formwork from creeping through the joint between the formwork and the frame 4 when concreting the building wall 1, the frame 4, as shown in FIG. 2, is attached in the area of both provided with a peripheral first seal 9, expediently designed as a sealing lip.
    The component 3 contains in addition to the frame 4 and the associated building opening 2 associated closure element in the form of a window or door, the associated window or door frame 5 is inserted into the frame 4 from the start. For this purpose, as can be seen from FIG. 2, this is provided with an inner profile 11 that matches an outer profile of the window or door frame 5, so that mutual engagement is possible. To achieve an airtight arrangement, the frame 4 is provided in the area of its inner profile 11 with at least one peripheral seal 12 that interacts with the inserted window or door frame 5, preferably in the form of a so-called compriband.
    In order to enable the window or door frame 5 interlocked with the frame 4 to be installed in the frame 4, the frame 4 is produced as a built-up component, the legs forming the sides of the rectangular frame 4 being joined at their ends and fixed to one another get connected. The window or door frame 5 is already inserted into the frame 4 when the frame 4 is assembled before the last leg is attached. The frame legs forming the frame 4 can be produced as sections of a longer profile floorboard, with the side forming the outer side 7 of the frame 4 being roughened before it is divided into the desired sections. Since the roughening results in a certain amount of material being removed, the extent of this removal is taken into account in the initial thickness of the profiled floorboard, so that the desired thickness of the legs of the frame 4 results after the roughening process.
    In the example on which Fig. 2 is based, an insulating frame 13 is arranged in front of the frame 4 on the outside of the building, which with its inward-facing side is attached to the outward-facing end face of the frame 4 and an area adjacent to it on the outside of the building wall 1 rests and connects to the thermal insulation 6 with its radially outer peripheral surface. The thickness of the insulating frame 13 corresponds to the thickness of the thermal insulation 6. The plaster layer forming the outside 7 can also extend over the insulating frame 13. This consists of an insulating material that is significantly more rigid than the thermal insulation 6 and is provided on both sides in the area next to the frame 4 with at least one bore 14 each, which is assigned to a retaining element built into the building wall 1, expediently in the form of a threaded sleeve 15. This makes it possible to subsequently attach a required component, for example a light shaft etc. assigned to a basement window, to the outside of the insulating frame 13 and to fasten it to the building wall 1 with the aid of screws that are passed through the lateral bores 14 and can be screwed into the assigned threaded sleeves 15 , At the same time the insulating frame 13 is secured. In simple cases, it is of course also conceivable to provide screws serving only to secure the insulating frame 13 . The insulating frame 13 can be designed in one piece or also be assembled from several parts.
    [0023] In order to prevent the formation of thermal bridges in a particularly reliable manner,
    2, an additional insulating frame 16 is provided, which rests with its radially outer peripheral surfaces on the radially inner peripheral surfaces of the insulating frame 13 and on the area of the inside of the frame 4 outside of the window or door frame 5 and which extends from the extends to the outside of the building pointing flank of the window or door frame 5 to the outside of the building and there is flush with the outer side 7 formed by the plaster layer or can be covered by this as the insulating frame 13. The insulating frame 16 can expediently consist of the same material as the frame 4, although roughening can be dispensed with here and a smooth, closed-pore surface is provided on all sides. Likewise, the insulating frame 16, like the frame 4, can be produced as a built-up frame with frame legs attached to one another. When using the same starting material, the insulating frame 16 therefore has a thickness of the insulating frame 16 that exceeds the thickness of the frame 4 by the thickness of the material removal required to roughen the outer peripheral surface of the frame 4.
