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 in burglar-resistant design, with a frame structure formed from frame elements and at least one peripherally bordered by frame elements filling, wherein the frame elements are each composed of an inner frame profile and thus connected by at least one connecting element outer frame profile, wherein the outer frame profiles are each provided with a burglar-resistant protective strip made of a resistant to abrasion, breakage and deformation material or the outer frame profiles themselves consist of a resistant to abrasion, breakage and deformation material and form a burglar-resistant protective strip, wherein the protective strips in each case at least by means of a fastener the associated inner and / or outer frame profile are connected.

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 profiles 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 Gain access to the interior of the building.

Furthermore, the gap areas between the filling elements weak points in the sense of bullet resistance, since they are even weaker compared to bullet-resistant filling elements.

task

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

solution

Starting from the known Gebäudeabschlüssen is proposed according to the invention on the one hand, that the protective strip on its back at least one, preferably integrally connected thereto, coupling element which extends approximately at a right angle to the plane formed by the protective strip and in one of the outer Frame formed profile frame or in a gap region on the front side of the filling, wherein the outer frame profile has at least one slot, which penetrates the at least one coupling element, and the coupling elements 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.

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. 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 coupling element may be a web welded to the respective protective strip, which runs continuously in the longitudinal direction of the respective protective strip, or may be formed by individual webs welded to the respective protective strips, which are arranged one behind the other in the longitudinal direction of the respective protective strips. In the case of individual spaced webs located in the outer frame profile Slot in the longitudinal direction of the protective strip run continuously or consist of individual, adapted to the webs slits.

As a further development of the invention, it is provided that the protective strips are in each case at least by means of a fastener with a profile region located in a space which is bounded on one side by the end face of the filling and on the other by the levels of the inner and outer sides of the filling, in particular one arranged there additional reinforcing insert, are connected. On the one hand, this significantly increases the stability of the connection and, on the other hand, the burglar resistance is increased by the additional coupling.

In one embodiment of this variant, the coupling element is connected to the reinforcing insert.

It is advantageous if the coupling element and / or the reinforcing inserts in an area between a first plane, defined by the outside of the filling, and a second plane, defined by the inside of the filling, is located.

Finally, it is advantageous if the protective strip fixing screw penetrates two walls of the rear chamber of the outer frame profile and the interposed coupling element in the form of a web and then with a parallel to the web and outside the chamber of the outer frame profile extending reinforcing insert in the form of a flat profile is screwed.

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

If the attachment of the protective strips such that they are each connected at least by means of a fastener to the associated outer frame profile and the latter in turn via at least one inner connecting element with the inner frame profile, the above object is achieved in that the fastening element is a bolt-shaped element, preferably one Screw, in particular a countersunk screw, which is secured by a securing element against rotation relative to the protective strip, wherein the securing element produces a positive connection between an outer shell of the bolt-shaped element and the protective strip. On Although this way the head of the fastening element can be visible from the outside of the building closure, it can not be dismantled by the fixing by means of the non-removable securing element.

An embodiment of the invention provides that a head of the bolt-shaped element are arranged in the protective strip, and a threaded portion of the bolt-shaped element (fastening element) is screwed to or in the inner frame profile or arranged in the inner frame profile reinforcing profile.

However, it is also conceivable that the screwing of the protective strips takes place by means of the fastening elements from the inside, so that the head of the fastening elements is located inside the outer frame profile, wherein the longitudinal direction of the frame elements staggered arrangement of the connecting elements in the conventional manner from the outside can take place.

Further, it is advantageous if the head of the bolt-forming element forming screw is penetrated by a securing element in the form of a locking pin or pin, which is used with an interference fit in a hole in the protective strip and the bolt-shaped element, in particular taken. Thus, the bolt-shaped element is fixed and a relative movement between the bolt-shaped element and the protective strip is no longer possible. Preferably, the outside end face of the securing element is flush with the outside of the protective strip.

It is particularly advantageous if the locking pin or bolt produces a form-fitting connection between the screw and the protective strip in a subsequent to the head shaft area. In this way, even after a possibly successful boring of the screw head, a relative movement between the then remaining screw shaft and the protective strip is prevented.

Furthermore, it is provided according to the present invention that the screw has a countersunk head, which does not project beyond the outside of the protective strip, and that the locking pin or bolt at the same angle to the outside of the protective strip, as the inclination angle of a Senkkegels a Through hole in the protective strip for the countersunk screw corresponds, and that the locking pin also does not protrude beyond the outside of the protective strip. This in turn serves for Prevention of relative movement between the fastener and protective strip and to prevent removal of the locking pin.

Advantageously, the inner connecting element connects an inner protective strip arranged in the outer frame profile below the protective strips to the inner frame profile, wherein the fastening element penetrating the (outer) protective strips is connected to the inner protective strips. The connection thus created is thus constructed in two stages. On the one hand, the (outer) protective strips are connected via the fastening element with the inner protective strips and, on the other hand, the inner protective strips are in turn connected by means of an inner connecting element with the inner frame profile, wherein the fastening element and the inner connecting element are offset from one another. It does not matter whether the inner connecting element is screwed from the inside, so that the screw head is located in the inner frame profile, or - as in the conventional case - from the outside.

For all the above-described embodiments of the invention, it is also particularly advantageous if at least one protective strip covers at least one edge region of one or more fillings.

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 ).

as FIG. 2 ; but with alternative attachment of the protective strip.

In the FIG. 1 is a horizontal section through a building completion 1 'according to the invention clarified, 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 each other via an inner connecting element 33, namely a screw. In the frame profiles 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 inner frame profile 3 in each case has an integrally formed screw channel 14 and is provided on the side facing the outer region A with a connecting profile 15, through which the inner connecting element 33 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 inner connecting element 33 is further surrounded by a sleeve 17 made of steel, so that the inner connecting element 33 is also protected in this area from violent destruction. Furthermore, a good bullet resistance in the shaft region between the filling elements is likewise achieved by a continuous profile 18 arranged there, which is provided in each case with a through-bore 19 in the region of connecting elements 33.

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.

The inner connecting element 33 is inserted from the outer side A of the building closure and formed by a countersunk screw, the countersunk head completely penetrates into an inner protective strip 27 between the profile 20 and the attachment profile 21. The thread of the countersunk screw engages in the connecting profile 15 and in the screw 14 of the inner frame profile 3 and thus connects this with the profile 20 of the outer frame profile 4th

In the event that the inner frame profile is in turn equipped with a reinforcing profile extending therein and not shown in the figure, the latter can likewise be equipped with a threaded bore in which the thread of the inner connecting element 33 engages.

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 33 can also be screwed to the inner protective strip 27.

In a behind or before lying level of the protective strip 23 is connected to a likewise formed as a countersunk screw fastener 34 so with the outer frame profile 4, that the thread of the fastener 34 first in the protective strip 23, then in the attachment profile 21 and finally in the inner protective strip 27 engages. Accordingly, the inner connecting element 33 and the fastening element 34 form separate elements. The countersunk head of the fastening element 34 is so far embedded in the protective strip 23 that it is flush with the outer edge 31 of the inner protective strip 23. Although the fastener 34 is already difficult to access in this way or arranged difficult to disassemble, however, two fuse elements 35 are provided in the form of locking pins to further increase the burglar safety, the head and a portion of the thread penetrate the countersunk screw and thus prevent movement of the same. The locking pins are hammered into the protective strips 23 by means of an interference fit such that their longitudinal axes run in each case parallel to that of the fastening element 34.

The outer frame profile 4 is provided with a cover 26, which serves on the one hand 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 represents a first, albeit weak obstacle in a break-in attempt.

The FIG. 1a shows the outside view of the protective strip 23 with the fastening means 34 and the two securing elements 35th

The Indian FIG. 1b For this reason, a stabilizing element 36 is arranged in the region of the end faces 8 of the filling elements 7, through whose threaded bore the inner connecting element 33 is guided or screwed. Alternatively to those in the FIG. 1 illustrated fuse elements 35 are the locking pins in the Figures 1b and 1c taken at an angle corresponding to the angle of inclination of the countersunk cone of the countersunk screw.

The Figure 1d shows a building closure 1 'in which the outer frame profile 4' is an integrally formed protective strip 23, which consists of an abrasion, breakage and deformation resistant material. The fastening element 25 'is screwed in from the outside area A, wherein it penetrates a sealing 52 located immediately behind the protective strip 23' and an insulating profile 53 and a hollow profile 54 located in the gap region of the filling elements 7 and is screwed into the inner frame profile 3 '. The head of the fastener 25 'is fixed by two securing elements 35 such that a rotation of the same even with the aid of all tools, such as a cutting disc, is not possible. For optical reasons, the outer frame profile 4 ', which simultaneously represents the protective strip 23', provided with a cover 26.

In the Figure 1e a building closure 1 'is shown, which has a frame 55 and a sash 56 and thus an inner frame profile 57, an inner sash profile 58, an outer frame profile 59 and an outer sash profile 60 comprises, wherein the respective outer and inner frame profiles in a conventional manner Dämmstege are interconnected. The filling element 7 ', a panel, is composed of a steel plate 61 facing the outer region A and an insulation 62 facing the inner region. The building closure 1 'is in turn provided on its side facing the outside area A with a protective strip 23 "which covers both the window frame 55 and the wing frame 56 - and thus a part of the filling 7' - The protective strip 23 'is by means of a fastening element 63, which is screwed in from the outside area A, connected to the frame 55, wherein the fastening element 63 penetrates the outer frame profile 59 and is screwed into a steel frame 64 arranged in the inner frame profile 57, which forms a connection profile 43 ' the fastening element 63 forming countersunk screw is in turn fixed with securing elements 35 and the protective strip 23 'is provided with a cover 26 for optical reasons.

In the FIG. 2 For example, a final 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 existing 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 formed 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 profile 4 is designed as a screw fastener 34 ', which connects the two webs 38 of the rear chamber 37 with the coupling element 41. To one To achieve greater stability of this compound, parallel to the webs 38 of the rear chamber 37 may be arranged a not shown in the figure reinforcing insert made of flat steel, which is provided with a threaded bore into which the fastener 34 'also engages. Thus, a kind of reinforcement of the threaded connection would be created.

Due to its location, the fastening element 34 'is not accessible from the outer 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 backfilling 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 ".

In order to connect the inner frame profile 3 and the outer frame profile 4 to the building, the profiles can be anchored to the building by means of dowels, which for the sake of clarity are only represented by the axes 50 in the figure.

At the in Fig. 2a shown alternative embodiment penetrates the likewise executed in the form of a screw fastener 34 'not only the two webs 38 of the rear chamber 37, in 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 of comparatively soft aluminum material outer frame profile 4, but in addition to the much more stable reinforcing profile 43 in a gap region S between the soffit L of an adjacent building part G and the outer frame profile 4 is located and therefore against tearing is secured. The inner frame profile 3 and the outer frame profile 4 are each connected by means of anchors 51 to the building part G.
