Abstract

The burglar-proof building facade (1) has a frame structure (2) with an outer frame profile (4) fitted with security strips (23), held by screw bolt and nut fasteners (25) to the frame structure. The fasteners cannot be accessed from the facade exterior and can only be reached when the filling (7) is absent. Reinforcement profiles are parallel to the frame structure, at the inside or outside and/or are bonded to the inner frame profile (3). The strips are resistant to abrasion, breakage or distortion.

Description

The invention relates to a building closure according to the preamble of claim 1.

For the purposes of the present application, a building closure is a flat closure element which can be designed to be openable or firmly closed and can be provided with a transparent or opaque filling. Such building closures are generally known as so-called post-and-beam facades whose vertical frame elements ("posts") and horizontal frame elements ("bars") form fields in which or in front of which filling elements are arranged. Windows of all kinds also fall under the definition of a building contract in the sense of this application.

The connecting elements of the inner and outer frame profile and the fastening elements of the frame profiles of the known from the prior art Gebäudeabschlüsse of buildings, which are usually protected by optical reasons by covers, can be relatively easily manipulated from the outside of the building by unauthorized persons, causing them Access to the interior of the building gain. Although the fasteners are protected by the protective strip and the inaccessibly arranged fasteners and difficult to locate for an intruder, but the fasteners are usually formed too weak, so that a levering of the entire protective strip is possible.

From the EP 0 825 323 A2 a burglar-proof window is known, the wooden frame is provided in each case on the inside and the outside with a metal strip, wherein the two opposite metal strips are connected to a bolt. The bolt is introduced from the inside of the window, so that it is inaccessible from the outside. The connection of the bolt with the outside facing metal strip via a weld.

The DE 34 01 877 A1 discloses a holding device for glazings, wherein a cover plate and a double pane are held between profile bars. The inner frame profile of the double disc is connected by means of a clamping screw with the outer frame profile, wherein the clamping screw is inserted from the inside and screwed into a nut located on the outside. Here, the mother is covered by a clamping bar, which is shaped so that its two ends engage under webs of the mother.

Furthermore, the describes EP 1 010 829 A2 a mullion-transom façade with an outer and inner frame profile. To secure the screwing of the outer frame profile with the inner frame profile, a collar bush made of a high-strength stainless steel is provided with a bore through which the screw is passed.

task

It is an object of the present invention to develop a building closure known type such that it is characterized by a further improved burglar resistance.

solution

The object is achieved with the features in characterizing the part of claim 1.

This means that an unauthorized person is unable to access the fastening element from the outside of the building closure or to destroy or move it in such a way that the connection to the building component would be lifted and after removal of the protective strip and further disassembly steps Access to the building interior is possible. In the case of a reinforcing profile tearing out of the fasteners together with the protective strip from the i.d.R. made of aluminum existing outer frame profile prevented. If the end of the fastening element to be actuated is located in the glazing rebate area, then manipulation with built-in filling is impossible, because then there is a covering of this area.

For the purposes of the present application, the protective strip is understood as the element that provides an initial resistance to an attack from the exterior of the building closure.

The fastener may simultaneously be the connecting element between the inner and outer frame profile, which is mounted against the usual practice of the interior of the building closure ago. For this purpose, an opening must be provided on the inside of the inner frame profile, so that the insertion of the connecting element, which is at the same time fastening element, is possible.

If the protective strip is threaded only up to a central region of its thickness, into which the fastening element is screwed in, the latter is not at all visible from the outside of the building closure, but from the outside Material of protective strips covered. The formation of the protective strips of a highly resistant material, the discovery and manipulation of the covered fastener is almost impossible.

Even in the event that the fastener completely penetrates the protective strip, it remains inaccessible from the outside insofar as at most the end thereof is recognizable from the outside, which, however, offers no possibility of attacking the dismantling or destruction of the fastening element. The fastener (which here is simultaneously connecting element), in particular the screw head or a nut on which only an actuation of the fastener is possible by rotation, thus remains inaccessible.

If the protective strips have a through-thread, which in turn is not completely penetrated by the fastening element, it is particularly advantageous if an end section of the threaded bore which is open to the outside of the building closure in the protective strip is fitted flush with the outer side of the closure body by means of a press-fitted closure body Closes protective tape, is closed. The fastener is thus covered by the closure body, which would have to be removed by an unauthorized person first, before the person could get to the end of the fastener. The end of the fastener is in turn difficult to manipulate or destructible, that the fixation of the protective strip and thus the connection of the frame members could be repealed. In particular, the introduction of a torque to unscrew the fastener is almost impossible for lack of appropriate targets.

For particularly high demands on the burglar resistance of a building closure, the protective strips made of hard metal, so that they can not be equipped with a threaded hole. In this case, it is particularly advantageous if the coupling element at the back of the protective strip materially connected thereto, that is in particular welded thereto, for example, soldered or shot (by stud welding), wherein the protective strips are rectangular in cross-section While the protective strip a Manipulation of the outside of the building closure make impossible, the coupling element, which can be advantageously equipped with a threaded hole, used to attach the protective strip with the frame profile.

An embodiment of the present invention provides that the fastening element is connected to a inside of the inner frame profile arranged reinforcing profile, wherein the reinforcing profile may be formed, for example, as a hollow profile. Such a reinforcing profile, which in contrast to the frame elements should be made of steel, is arranged inside the inner frame profile in order to increase the stability of the building closure and the connection between the frame profiles.

In all cases, the arrangement of the protective strips to protect the fastener also provides a good bullet resistance in the same area.

According to the invention, it is further provided that the protective strip has at its rear side at least one, preferably integrally connected, coupling element which runs approximately at right angles to the plane formed by the protective strip and into a chamber formed by the outer frame profile or into a gap region the end face of the filling protrudes, wherein the outer frame profile has at least one slot, which penetrates the at least one coupling element, and the Kopp-Iungselemente are each connected by means of a fastening element with the associated frame member. In building closures, which have a glare and sash, the gap area may in particular also be the fold area.

In addition, the building closures according to the invention achieve particularly good results, both with regard to their burglar resistance and with respect to their bullet resistance, if the protective strip has at least a thickness of 6 mm, preferably 8 mm, preferably 10 mm, preferably 12 mm, more preferably 15 mm and is made of metal, preferably steel, hard steel or hard metal or aluminum with a high tensile strength (> 250 N / mm ² ).

Fig. 2

a horizontal section of another alternative building closure.

In the FIG. 1 is a horizontal section through a building completion 1 according to the invention, from which the structure of the frame elements 2 emerges. The frame members 2 made of aluminum consist of an inner frame profile 3 and a parallel thereto extending outer frame profile 4, which are connected to one another via a connecting element 5, namely a screw. In the frame sections 3, 4 each sealing rubbers 6 are clipped, between which filling elements 7 of the building closure 1 are held so that the end faces 8 are circumferentially bordered by the frame members 2. The connecting element 5, which is introduced from an inner region I of the building closure 1 via an opening 9 in the inner frame section 3, is supported by a trained as a head 10 end over a washer 11 on an outer region A of the building 1 facing wall 12 of the inner Frame profile 3 from. In the event that the inner frame profile 3 is equipped with a reinforcing profile (not shown in the figure), for example a hollow profile, the connecting element 5 can likewise be connected to the reinforcing profile, so that the stability of the building closure 1 is increased.

For reasons of appearance, the inner frame profile 3 is provided with a cover 13 from the inner region I, so that the openings 9 are not visible.

The inner frame profile 3 has in each case an integrally formed screw channel 14 and is provided on the side facing the outer region A with a connection profile 15, through which the connecting element 5 is guided. The connection profile 15 is geometrically adapted to the outer contour of the inner frame profile 3 in such a way that it covers the screw channel 14. It is in the inner frame profiles 3 located grooves with undercuts 16 inserted in the longitudinal direction of the profiles and connected by engagement with the undercuts 16 with this form-fitting manner.

In the area of the end faces 8 of the filling elements 7, the connecting element 5 is further surrounded by a sleeve 17 made of steel, so that the connecting element 5 is protected in this area from violent destruction. Furthermore, a good bullet resistance is also achieved in the shaft region between the filling elements 7 by a continuous profile 18 arranged there, which is provided in the region of connecting elements 5 with a through-bore 19 in each case.

The outer frame profile 4 is composed of a profile 20 and an attachment profile 21. On the outside A side facing the outer frame profile 4 is provided with a threaded bore 22 having protective strip 23 made of flat steel, in which a thread 24 of the connecting element 5 engages, whereby the attachment profile 21 and the profile 20 are held together with the inner frame profile 3. The connecting element 5 is also used as a fastening element 25 which connects the protective strips 23 to the frame element 2, in particular to the inner frame profile 3, and thus performs a dual function. Also, the outer frame profile 4 is provided with a cover 26, on the one hand serves to improve the optical properties of the building closure 1, because the protective strips 23 are not visible from the outside, and on the other hand represents a first, albeit weak obstacle in a break-in attempt. The fastening element 25 or the connecting element 5 is embedded in the protective strip 23, which is made of steel or an alternative resistant material, so that it is inaccessible from the outer area A of the building closure 1. Although an unauthorized person can first remove the cover 26 of the outer frame profile 4, but then they find only a minimal of the protective strip 23 protruding end of the fastener 25 and not about an exposed screw head, which may be rotatable and the due to the nature of the invention Screw would thus be solvable. Even with the aid of any typical breaking tools, such as lever-type (cow-foot) or even a drill or angle grinder, access to the fastener 25 is impossible during the time period prescribed for the test because the protective strips 23 have high strength and machining the same is not possible without further notice.
On the one hand, the destruction of the fastener 25 is prevented due to its embedding in the protective strip 23, on the other hand, however, the fastener 25 can not be rotated and thus not solved. Access to the building interior is therefore not possible by dismantling the frame members 2.

Further, in the outer frame profile 4 in a region between the profile 20 and the attachment profile 21, a further inner protective strip 27 is arranged, which is also connected by means of the connecting element 5, which engages in a through hole 28 of the inner protective strip 27 with the inner frame profile 3 , The inner protective strip 27, which has significantly smaller dimensions than the protective strip 23, in turn increases the burglary resistance, since it represents a second "blockade" for the attack of an unauthorized person. Alternatively, the inner protective strip 27 instead of the through hole 28 have a threaded bore, so that the connecting element 5 can also be screwed to the inner protective strip 27.

Further, it is possible to have the inner protective strip 27 in one not in the FIG. 1 level shown, for example, by means of a countersunk screw from the outside with the profile 20 of the outer frame member 4 to screw and thus to fix.

The horizontal section shown in Figure la of a building closure 1 according to the invention differs from that according to the FIG. 1 only by the connecting element 5 ', which is formed substantially longer and extends approximately over the entire depth of the building closure 1. The connecting element 5 'is also formed from the interior of the building closure 1 via an opening 9', which is smaller than according to the FIG. 1 , inserted into the inner frame profile 3, wherein the head of the connecting element 5 'is supported by a washer in the edge region of the opening 9' on a wall 29 of the inner frame profile 3 facing the inner region I. The protruding from the inner frame section 3 head 10 of the connecting element 5 'is covered by the cover 13.

In the Figures 1b and 1c are shown alternative embodiments of the connection of the protective strip 23 with the frame member 2, wherein the remaining structure does not differ from that in the FIG. 1 shown differs.

In the FIG. 1b If the thread 24 of the connecting element 5 "is shorter, so that it engages only approximately halfway into the threaded bore 22 of the protective strip 23. This corresponds to a shorter design of the fastening element 25, formed here by the connecting element 5" by the double function becomes. The open to the outside area A of the building completion 1 end portion of the threaded hole 22 of the protective strip 23 is closed by means of a fitted with a press fit closure body 30 in the form of a hardened steel ball, which is flush with the outer side 31 of the protective strip 23. In this way, access to the fastening element 25 from the outer area A of the building closure 1 is prevented. In the Figure 1c For example, the connecting element 5 "is designed so short that it does not engage in the protective strip 23. Instead, a coupling element 32 designed as a sleeve and having a threaded bore is soldered to the protective strip 23, into which the connecting element 5" is screwed. Such a design is required when the protective strip 23 is made of hard metal, which can not be provided with a threaded hole, nor can be welded to other elements.

The fastening element 25, which serves to connect the protective strips 23 to the frame element 2, is again formed by the connecting element 5 "Since the protective strip 23 shields the coupling element 32 from the outer region A of the building closure 1, this and the fastening element 25 are unauthorized Persons arranged inaccessible and greatly impeded or prevented penetration of the same in the building.

In Figure 1d is a building completion 1 shown, the inner frame section 3 'consists of a square hollow section. The outer frame profile 4 'is designed such that it itself forms a burglar-resistant protective strip 23'. At its rear side, the protective strip 23 'integrally formed with the outer frame profile 4' is analogous to that in FIG Figure 1c illustrated protective strip 23 equipped with a coupling element 32 ', in which the fastening element 25', which is thus covered by the outer region A forth by the protective strip 23 ', is screwed.

In the FIG. 2 Another example of an embodiment of the present invention is shown. The outer frame profile 4 of the building closure 1 'has a rear chamber 37, which projects into a gap area along the end face 8 of the filling element 7. The rear chamber 37, which has two parallel webs 38 is coupled by means of glass fiber reinforced polyamide Dämmstegen 39 as connecting elements 33 with the two-part outer frame profile 4.

The protective strip 23 located in the outer frame profile 4 is connected via welds 40 to a coupling element 41, which is designed as a flat steel and embedded in the rear chamber 37 of the outer frame profile 4, wherein the coupling element 41 is formed as a continuous element or only as a short piece can be. For this purpose, an adapted slot 42 is provided in each case in the outer frame profile 4. For frictional connection of the protective strip 23 with the outer frame section 4 is designed as a screw fastening element 34 which connects the two webs 38 of the rear chamber 37 with the coupling element 41.

Due to its location, the fastening element 34 is not accessible from the exterior area A of the building closure 1 '.

The two-part inner frame profile 3 consists of a first chamber-like profile 44 with two webs and a second profile 45. The chamber formed by the first chamber-like profile 44 may be provided with an aluminum insert, not shown in the figure. A screw 47 connects the two elements of the inner frame profile 3 and forms a glass retaining strip. The filling element 7 arranged between the inner frame profile 3 and the outer frame profile 4 is held on both sides by means of sealing rubbers 6. A pressure-resistant back-lining 49 arranged in the region of the end face 8 of the filling element 7 ensures a non-positive retention of the building closure 1 '.

At the in Fig. 2 In the embodiment shown, the fastening element 34 designed in the form of a screw penetrates not only the two webs 38 of the rear chamber 37 into which the coupling element 41 is inserted. The fastening element 34 is further screwed with its threaded portion still in a consisting of a flat steel reinforcing insert 43 in threaded holes introduced therein. The attachment of the protective strip 23 thus takes place not only on the two webs 38 of the existing relatively comparatively soft aluminum outer frame profile 4, but in addition to the much more stable reinforcing profile 43, extending in a gap region S between the soffit L of an adjacent building part 52 and the outer frame profile 4 is located and is therefore secured against tearing. The inner frame section 3 and the outer frame section 4 are each connected by means of anchors 51 to the building part 52.
