Description
[0001] The invention relates to a building closure arrangement for mounting on the building envelope of a building, comprising a building closure and a fastening element for attaching the building closure to the building envelope, wherein the building closure has a frame, in particular one supporting glazing, with several frame members, wherein the fastening element is provided and designed for positive locking attachment of at least one of the frame members to the building envelope and for this purpose has a positive locking area overlapping the at least one frame member and a fastening area connected to the positive locking area and arranged next to the frame member for attachment to the building envelope, wherein the positive locking area overlaps a frame member area of the at least one frame member in cross-section, so that the frame member area is held clamped in a first direction in cross-section between the positive locking area and the building envelope.wherein the fastening area has a bearing surface for support on the building envelope, which is aligned with a bearing surface of the at least one frame member facing the building envelope.
[0002] The invention further relates to a building with a building envelope and a building closure arrangement for placement on the building envelope.
[0003] For example, the prior art document EP 2 886 772 A1 describes a device for fixing a window or door in a wall opening of a building, comprising at least one wall bracket and a component bracket connectable to the wall bracket, wherein the wall bracket has at least two fixing openings and at least one connecting opening. The connecting opening is designed as a slot open towards the window or door.
[0004] Furthermore, EP 3 683 377 A1 discloses an insulating frame for a roof window mounted in a sloping roof structure of a building, comprising an upper, a lower and side frame members, each having an insulating member and a support member, and a plurality of connector brackets, wherein the insulating frame defines an inner opening designed to surround a frame of the roof window, and wherein the insulating frame has an inner side designed to face into the interior of the building and an outer side designed to face outwards, and wherein each frame member has an inner side facing the inner opening and an outer side facing away from the inner opening, wherein the insulating frame further defines a base plane on the inner side of the insulating frame members that is substantially parallel to the inner opening.The insulation frame is provided to include a set of roof connector brackets designed to connect the insulation frame to the roof structure and at least one attachment section, each roof connector bracket comprising a first connection section and a second connection section, the first connection section being connected to an attachment section and the second connection section being designed to be connected to the roof structure, and extending in the assembled state parallel to the base plane and beyond the outside of the frame member to which the roof connector bracket is attached, away from the inner opening of the insulation frame, the attachment section(s) allowing each roof connector bracket to be attached in several different positions depending on the design of the roof structure.
[0005] Further state of the art is described in the publications EP 1 512 806 A1, WO 99 / 35355 A1, US 4,995,208, US 2008 / 0086878 A1 and FR 2 725 263 A1.
[0006] The object of the invention is to propose a building closure arrangement for placement on the building envelope of a building, which has advantages over known building closure arrangements, in particular enabling quick and convenient mounting of the building closure on the building envelope, which also achieves a permanent and reliable attachment of the building closure to the building envelope.
[0007] According to the invention, this is achieved with a building closure arrangement for mounting on the building envelope of a building with the features of claim 1. It is provided that the positive locking area encompasses the frame member area of the at least one frame member in cross-section, such that, viewed in cross-section, it engages the frame member area on opposite sides in a second direction different from the first.
[0008] Advantageous embodiments with appropriate further developments of the invention are specified in the dependent claims.
[0009] The building closure device serves to close the building, at least temporarily, and in particular to close an opening formed in the building envelope. The building closure device comprises both the closure itself and the fastening element by which the closure is attached, or at least can be attached, to the building envelope. The building envelope preferably consists of the building's walls or roof. Both the walls and the roof lie between the building's exterior and interior spaces, thus separating them. The opening in the building envelope, which is closed, at least temporarily, by the building closure device or the closure itself, is therefore either a wall opening or a roof opening.
[0010] The wall is designed specifically as the exterior wall of the building. The roof, on the other hand, essentially consists of a roof structure and a roof covering. The roof structure includes, for example, one or more rafters and one or more battens. The battens can be divided into counter battens and purlins, although the presence of counter battens is purely optional. The purlins are usually angled, particularly perpendicular, to the rafters and attached to them. The counter battens, however, preferably run at an angle to the purlins, particularly perpendicular to them, and / or parallel or at least substantially parallel to the rafters.
[0011] The roof covering is attached to the exterior of the roof structure, thus defining its boundary with the outside environment. The roof covering refers specifically to the roofing material or roof waterproofing. This roofing material might consist of a variety of roof tiles, shingles, or similar materials. On the interior side, the roof structure is typically bounded by an interior wall. This interior wall is attached to the roof structure on its interior-facing side. For example, the building's exterior wall might be connected to the interior wall via an interior lining.
[0012] The building closure is preferably designed as a door or a window. The window can be a roof window, in particular a residential roof window or a skylight, or alternatively a facade window. The building closure can be designed to close the opening in a light-transmitting or opaque manner. If the building closure is light-transmitting, it includes glazing, which can be single glazing or multiple glazing, in particular double glazing or triple glazing. In any case, the building closure includes a frame, which in turn has several frame members. If glazing is present, it is supported by the frame. Preferably, it is enclosed by the several frame members.
[0013] The frame members are attached to one another in such a way that they enclose a section of the building closure between them. The frame members thus form a closed frame. The frame, or the multiple frame members, are specifically designed to overlap and / or cover the opening in the building envelope. Preferably, the frame members are arranged and designed such that, together with the glazing, they completely close the opening, at least temporarily. The building closure can be permanently closed, i.e., designed to permanently close the opening. However, it can also be provided that the building closure can be opened and closed. In this case, the frame is preferably a frame with a sash frame of the building closure that is movable, in particular pivotable.If the sash frame is present, the glazing is preferably attached to it and is only indirectly supported by the frame or blind frame via the sash frame.
[0014] The building lock is attached to the building envelope using a fastening element. It is common practice to use multiple screws as fasteners. However, this usually requires a large number of screws, especially if the frame is made of plastic. In this case, screws must be spaced between 100 mm and 300 mm apart, resulting in a significant number of screws. This leads to high material consumption and considerable effort during the installation of the building lock, specifically when attaching it to the building envelope. Alternatively, the frame can be reinforced, particularly with steel, and mounting brackets can be attached to this reinforcement. In this case, the mounting brackets are fastened to the building envelope using screws, thus ultimately securing the building lock to it.This results in poorer thermal insulation due to the reinforcement, a higher weight of the window, and in turn, a higher material usage.
[0015] For this reason, the invention provides that the fastening element serves to positively lock the frame, or at least one of the frame members, to the building envelope and is designed accordingly. The fastening element comprises a positive locking area and a fastening area, which are connected or attached to each other. Preferably, the fastening element is made in one piece from a single material; preferably, the positive locking area and the fastening area are manufactured together and connected, for example, by extrusion.
[0016] The positive locking area overlaps at least one frame member, at least partially, in such a way that it presses the frame member towards the building envelope after the building closure assembly has been mounted on the building envelope, or holds it in place there. The fastening area, on the other hand, is located next to the frame member and is attached to the building envelope, or at least attachable to it. The fastening element, and in particular the fastening area, is preferably screwed to the building envelope, using at least one fastening device, especially at least one screw.
[0017] It is possible for the fastening element to engage only a single frame member. However, it is also possible for the fastening element to engage several frame members, particularly on multiple sides of the building closure. In this case, the fastening element can be designed as a fastening frame, preferably a closed fastening frame, which completely encircles the building closure element or its frame. Of course, the fastening element can also be an open frame and, for example, be L-shaped or U-shaped. In the former case, the fastening element has two legs angled towards each other; in the latter case, three legs are provided, with two of these legs spaced apart and connected to each other via a third leg.
[0018] Preferably, the building closure is attached to the building envelope using multiple fastening elements. In addition to the primary fastening element, at least one further fastening element is provided, which engages a different frame member than the primary fastening element. In other words, the primary fastening element engages at least one of the frame members, and at least one further fastening element engages at least one other of the frame members. Particularly preferred in this type of fastening of the building closure to the building envelope is that each frame member is attached to the building envelope with its own separate fastening element.
[0019] Alternatively or additionally, the building closure can be attached to the building envelope on its side opposite the fastening element by means of a rear-engaging device. The rear-engaging device comprises a first rear-engaging element located on the building closure and a second rear-engaging element attached to the building envelope. The two rear-engaging elements are brought into engagement with each other in a specific installation direction. This means that the building closure is moved along the installation direction from a first position relative to the building envelope to a second position, whereby the building closure is freely movable in the first position relative to the building envelope and is fixed in at least one direction relative to the building envelope in the second position, different from the installation direction.After the locking mechanisms are engaged, the frame is additionally secured to the building envelope using the fastening element. The fastening element specifically prevents the building closure from shifting out of the second position, thus keeping the two locking mechanisms engaged and ensuring a reliable and permanent attachment of the building closure to the building envelope.
[0020] Preferably, the building closure, or the at least one frame member attached to the building envelope by means of the fastening element, has a projection that extends beyond a base element of the frame member and is overlapped by the positive locking area. If the building closure has a cover plate, in particular a cover plate that overlaps the sash frame and / or the frame, the projection preferably extends beyond this cover plate in cross-section. In cross-section, the cover plate overlaps, in particular, a sash frame member and the base body of the frame member completely, but not the projection. Preferably, however, the cover plate overlaps, in cross-section, at least partially, in particular by at least 50%, at least 75%, or at least 90%. This ensures a weatherproof design of the building closure assembly.
[0021] A further development of the invention provides that the positive locking area, spaced apart from the fastening area, has a positive locking projection which engages in a positive locking recess formed in the at least one frame member. The positive locking projection and the positive locking recess serve to additionally secure the fastening element and the at least one frame member to one another. The positive locking recess is preferably in the form of a groove which extends longitudinally along the frame member and penetrates at least 50%, at least 75%, or completely through it in this direction. Similarly, the positive locking projection is in the form of a continuous web which also extends over at least 50%, at least 75%, or over the entire longitudinal extent of the frame member and engages continuously in the positive locking recess. Particularly preferably, the positive locking projection projects towards or extends in the direction of the building envelope.For example, in cross-section it stands perpendicular to this, ensuring a particularly reliable hold of the fastening element on at least one frame member.
[0022] Additionally or alternatively, the form-fitting recess projects towards the building envelope. In the case of a form-fitting projection, this means that a free end of the projection points towards the building envelope. The depth direction of the form-fitting recess, i.e., the direction between its opening and its base opposite the opening, runs towards or intersects the building envelope. The form-fitting recess, or its depth direction, is angled relative to the building envelope and forms an angle of more than 0° and less than 180° with it, in particular an angle of at least 80° and at most 100°, preferably approximately or exactly 90°.Preferably, the positive locking projection and / or the positive locking recess extend in the same direction as a fastening means by which the fastening element can be attached to or is attached to the building envelope, i.e., they are arranged or aligned parallel to it. The described design of the building closure assembly ensures reliable and permanent attachment of the building closure to the building envelope.
[0023] According to the invention, the positive locking area overlaps a frame member section of the at least one frame member in cross-section, such that the frame member section is arranged between the positive locking area and the building envelope. The frame member section essentially corresponds to the aforementioned projection. The frame member section has a lower height than the entire frame member, particularly in a direction perpendicular to the building envelope. For example, the frame member section has an extent in this direction of at most 50%, at most 40%, at most 30%, or at most 20% of the extent of the entire frame member in the same direction. The frame member section is arranged between the positive locking area of the fastening element and the building envelope such that it is pressed by the positive locking area toward or against the building envelope.According to the invention, the frame member area is clamped between the positive locking area of the fastening element and the building envelope. This ensures a permanent and reliable fastening of the building closure to the building envelope.
[0024] The invention provides that the positive locking area encompasses the frame member area of at least one frame member in cross-section, so that it is located on opposite sides of the frame member area in cross-section. This is achieved in particular by the engagement of the positive locking projection in the positive locking recess. Thus, the positive locking area is located on opposite sides of the frame member area in a direction parallel to the building envelope. This further improves the holding effect of the fastening element on the building closure.
[0025] Furthermore, the invention provides that the fastening area has a bearing surface for contact with the building envelope, which is aligned with a bearing surface of the at least one frame member facing the building envelope. Thus, both the fastening area and the building envelope each have a bearing surface over which they rest against or are supported by the building envelope. At least after the building closure is fastened to the building envelope, but preferably even before, the two bearing surfaces of the fastening area and the at least one frame member are aligned with each other. This ensures a reliable fastening, particularly without excessive deformation of the fastening element.
[0026] A further development of the invention provides that the fastening element has at least one through-opening in the fastening area for receiving a fastening element by means of which the fastening element can be attached to the building envelope. The fastening element is understood to be, in particular, a screw. The through-opening is thus designed as a screw hole. The through-opening is dimensioned such that the head of the screw arranged in the through-opening holds the fastening element to the building envelope or presses it towards the building envelope. Preferably, the fastening element has several through-openings for receiving several fastening elements or screws.Preferably, no more than five screws are provided for fastening at least one frame member to the building envelope, so that the fastening element used to fasten the entire frame member has no more than five through-holes. This results in less effort when attaching the building closure to the building envelope. The fastening element, or the through-hole in which the fastening element is arranged, preferably runs parallel or at least nearly parallel to the positive-locking projection and / or the positive-locking receptacle. In other words, a longitudinal center axis of the through-hole is aligned parallel or nearly parallel to the positive-locking projection and / or the positive-locking receptacle. Consequently, the positive-locking projection is pressed into the positive-locking receptacle by the fastening element and securely held therein.
[0027] A further development of the invention provides that the frame member is designed as a hollow profile member. This means that the frame member is not made of solid material, but rather has air chambers which are at least partially or completely enclosed by the frame member material. This results in a particularly low weight combined with high stability of the frame member. It is especially preferred that the section of the frame member which is attached to the building envelope by means of the fastening element is designed with such a hollow profile, so that the frame member section is partially hollow. The hollow profile is characterized in particular by several air chambers which are aerodynamically separated from one another by webs made of the frame member material.
[0028] A further development of the invention provides that the frame member area is designed with a single material, in particular without reinforcement. At least in the frame member area, the frame member consists solely of a specific material and not of different materials. This is not contradicted by the fact that the frame member area, as explained above, has the hollow profile or is designed as such. The hollow profile is formed by the specific material; for example, the webs consist of the specific material. Specifically, the material-uniform design means that at least the frame member area, but preferably the entire frame member and / or the entire frame, is designed without reinforcement, i.e., it has no reinforcement made of a reinforcing material that is different from the material of the frame member and, in particular, is stiffer than it.
[0029] Reinforcement is typically used to stiffen the frame member or the frame itself. As previously explained, reinforcement can also serve to attach the frame to the building envelope, for example, by attaching fasteners to both the reinforcement and the building envelope. However, such a design should be avoided whenever possible, as it results in a heavy building closure. The described material-uniform and, in particular, reinforcement-free design of the frame member area thus creates a particularly lightweight building closure element that can also be attached to the building envelope easily and reliably.
[0030] A further development of the invention provides that the frame is a wooden frame or a plastic frame, or at least partially made of plastic, and / or that the fastening element is a plastic element. The material of the frame is either wood or a plastic, preferably a thermoplastic polymer. In the former case, the frame is particularly solid, so that the frame member is not a hollow profile. In the case of the plastic frame, the frame member is preferably a hollow profile. The frame can also consist only partially of plastic or contain plastic. For example, the frame is a wooden frame encased in plastic. For instance, polyvinyl chloride (PVC) is used as the material for the frame or the frame member. For the plastic frame, the frame consists entirely or at least predominantly, i.e., in particular to at least 75% by weight, of plastic.-%, at least 90% by weight or at least 95% by weight of plastic. This allows for a particularly lightweight building closure.
[0031] Additionally or alternatively, the fastening element is made of plastic. For example, the fastening element is made of the same plastic as the frame. Preferably, however, the material of the fastening element is stiffer than the material of the frame. Overall, the described design of the building closure assembly achieves a stable and easy-to-manufacture fastening of the building closure to the building envelope.
[0032] A further development of the invention provides that the fastening element is an extruded element. This means that the fastening element is manufactured by extrusion. Preferably, a blank is first formed by extrusion and then cut to length to produce the fastening element. In particular, the fastening element is manufactured exclusively by extrusion and cutting to length. Optionally, at least one through-hole is formed in the fastening element, for example, by drilling. This enables a cost-effective implementation of the fastening element.
[0033] The invention further relates to a building with a building envelope and a building closure arrangement for mounting on the building envelope, in particular a building closure arrangement as described in this description, wherein the building closure arrangement comprises a building closure and a fastening element for attaching the building closure to the building envelope of the building, and the building closure has a frame, in particular one supporting glazing, with several frame members, wherein at least one of the frame members is positively attached to the building envelope by means of the fastening element, and the fastening element for this purpose has a positive locking area overlapping the at least one frame member and a fastening area connected to the positive locking area and attached to the building envelope and arranged next to the frame member for attachment to the building envelope.
[0034] The positive locking area overlaps a frame member section of the at least one frame member in cross-section, such that the frame member section is clamped between the positive locking area and the building envelope in a first direction. The positive locking area also encompasses the frame member section of the at least one frame member in cross-section, so that it engages the frame member section on opposite sides in a second direction, different from the first. The fastening area has a bearing surface for contact with the building envelope, which is aligned with a bearing surface of the at least one frame member facing the building envelope.
[0035] The advantages of such a building design and / or building closure arrangement have already been mentioned. Both the building and the building closure arrangement can be further developed as described in this document, and reference is made to those details.
[0036] The features and combinations of features described in the description, in particular those described in the following figure description and / or shown in the figures, can be used not only in the combinations specified, but also in other combinations or individually, without departing from the scope of the invention as defined in the accompanying claims. Thus, embodiments that are not explicitly shown or explained in the description and / or the figures, but which emerge from or can be derived from the explained embodiments, are also to be considered as encompassed by the invention.
[0037] The invention is explained in more detail below with reference to the exemplary embodiments shown in the drawing, without limiting the invention. The only embodiment shown is... Figure 1 is a schematic representation of a building with a building envelope and a building closure arrangement.
[0038] The Figure 1Figure 1 shows a schematic sectional view of a building 1, which has a building envelope 2 and a building closure assembly 3. In the embodiment shown here, the building envelope 2 is a roof, specifically a flat roof. A recess 4 is formed in the building envelope 2, which extends completely through the building envelope 2 and thus connects an exterior environment 5 of the building 1 with an interior environment 6 of the building 1, particularly in terms of airflow and / or optics or lighting. The recess 4 is closed by a building closure 7 of the building closure assembly 3, particularly in terms of airflow. In the embodiment shown here, the building closure 7 is a skylight with glazing 8, so that an optical connection between the exterior environment 5 and the interior environment 6 is maintained through the recess 4.
[0039] In the embodiment shown here, the building closure 7 has a frame designed as a frame 9 and a sash frame 10, wherein the sash frame 10 supports the glazing 8 and is displaceable, in particular pivotable, relative to the frame 9. In cross-section, the sash frame 10 is completely and the frame 9 at least partially covered by a cover plate 11. In cross-section, the cover plate 11 extends over the glazing 8 and, in the direction away from the glazing 8, over the frame 9. At least one seal 12 can be arranged between the cover plate 11 and the frame 9 and / or the sash frame 10. At least one further seal 13 can be present between the frame 9 and the sash frame 10.
[0040] The frame 9 has several frame members 14, of which only one is shown here. The frame member 14 has a base body 15 from which a frame member section 16 extends, particularly in cross-section, in the direction away from the glazing 8, i.e., outwards. On its side facing the glazing 8, the frame member 14 has a first positive locking device 17, which interacts positively with a second positive locking device 80 formed by the recess 4 to secure the building closure 7 laterally with respect to the building envelope 2. For this purpose, the first positive locking device 17 is designed as a positive locking projection that engages in the recess 4 and bears, at least temporarily, preferably permanently, against an edge 19 of the recess 4 formed by the building envelope 2 and bounding the recess 4.However, the fastening of the building closure 7 by means of the first positive locking device 17 and the second positive locking device 18 is purely optional and can be omitted.
[0041] A fastening element 20 serves to permanently attach the building closure 7 to the building envelope 2, by means of which the frame member 14 is positively locked to the building envelope 2. For this purpose, the fastening element 20 has a positive locking area 21 and a fastening area 22. The positive locking area 21 overlaps the frame member 14, in particular the frame member section 16, at least partially. The fastening area 22, on the other hand, is arranged next to the frame member 14 and in particular next to the frame member section 16 and rests at least partially against the building envelope 2. Preferably, the fastening area 22 is fastened to the building envelope 2 by means of at least one fastening element 23, here designed as a screw. The fastening element 20 is designed and arranged and fastened to the building envelope 2 in such a way that it holds the frame member 14 and thus the building closure 7 to the building envelope 2.Additionally, it prevents the positive locking devices 17 and 18 – if present – from disengaging from each other. Accordingly, the building closure 7 is reliably and permanently fixed to the building envelope 2.
[0042] It is evident that the positive locking area 21 overlaps the frame member area 16 in cross-section, completely so in the initial example shown here. Accordingly, the frame member area 16 is clamped between the positive locking area 21 and the building envelope 2 in a first direction. Furthermore, the positive locking area 21 encompasses the frame member area 16 in such a way that, in cross-section, it engages it on opposite sides of the frame member area 16 in a second direction, different from the first.
[0043] The frame member section 16 is thus arranged in the first direction between the positive locking area 21 and the building envelope 2, and in the second direction, which differs from the first, between opposite sides of the positive locking area 21. The second direction is angled relative to the first direction, thus forming an angle with it that is greater than 0° and less than 180°. Preferably, the angle is at least 70° and at most 110°, at least 80° and at most 100°, or approximately or exactly 90°. In the embodiment shown here, the fastening element 20, or rather its positive locking area 21, has a positive locking projection 24 that engages in a positive locking recess 25 of the frame member 14, which is a groove. This effectively prevents the building closure 7, or the frame member 14, from detaching from the fastening element 20 and thus from the building envelope 2.
[0044] The described design of building 1, or rather of the building closure assembly 3, enables the reliable and permanent attachment of the building closure 7 to the building envelope 2. This is also achieved with extremely simple installation, since ultimately only the building closure 7 needs to be positioned on the building envelope 2 and fastened using the fastening element 20. Of course, several fastening elements 20 are preferably provided for attaching the building closure 7 to the building envelope 2, which are arranged on different sides of the building closure 7 and engage with it.
