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 plate-shaped filling, wherein the frame elements are each composed of an inner frame profile and thus connected by at least one fastener outer frame profile, each Filling is held by at least two arranged on opposite end faces of the filling outer frame profiles, which are each provided with a burglar-resistant protective strip of a resistant to abrasion, breakage and deformation material or even made of a resistant to abrasion, breakage and deformation material and a form burglar-resistant protective strip, wherein the protective strips are connected in each case by means of at least two fastening elements with the inner frame profile and the Fastening elements of a provided with the protective strip outside of the Gebäudeabschlusses forth the associated protective strip, possibly penetrate the outer frame profile and a gap between two adjacent fillings or between a filling and an adjacent part of the building, wherein the fastening elements are each designed as a bolt-shaped element and on a protective strip associated first end are each provided with a first head member projecting in the radial direction over a diameter of the bolt-shaped element, so that in cooperation with a breakthrough in the protective strip, a positive connection between the fastener and the protective strip with respect to a transmission of a longitudinal direction the bolt-shaped element directed tensile force is formed.

Under a building contract within the meaning of the present application, on the one hand facade constructions, typically those in mullion-transom design, but also objects of the so-called "element building", ie window and door constructions, as well as arranged inside buildings partition wall constructions are to be understood with one part of the building is closed to another part of the building.

Due to the use of burglar-proof protective strips, such building closures can also withstand massive tool attacks (angle grinder, drill, "cow's foot", sledgehammer, etc.) within a certain time and can therefore be used e.g. meet the requirements of the burglary resistance standard in resistance class WK5 of DIN V ENV 1627. The fillings used in each case must also be made very resistant, which usually runs out in transparent fillings on the use of multi-layer glued together individual glass or polycarbonate glass, whereas alternatively also massive metallic fillings are possible if transparency is not required. With appropriate design of the protective strip, it is also possible that with such building completions the requirements for bullet resistance are met.

State of the art

A building completion of the type described above is for example from the EP-A-1 970 523 known. The aforementioned document discloses three different variants of how a disassembly of the protective strip can be prevented in an attack attempt from the outside of the building closure ago. A disassembly of the protective strip is therefore for an attacker usually the key to a successful burglary, because then without much difficulty the possibly underlying outer frame profiles that press the fillings against the inner frame profiles as a kind of clamping rail, can be destroyed. Once this condition has been reached, it is possible, after the removal of at least three outer frame profiles, to remove one and the same rectangular filling, the latter, so that access to the interior of the building has been created.

In a first embodiment of the building closure according to the EP-A-1 970 523 the protective strips are connected from the inside of the building closure by means of helical connecting elements with the respective inner frame profile. The coupling of the fasteners to the protective strip is carried out either through therein threaded holes into which an end-side threaded portion of the bolt is screwed from the inside, or via a coupling element, for example in the form of a soldered threaded sleeve, in turn, the end-side threaded portion of the fastening screw is screwed.

Conversely, a second embodiment of the aforementioned document is based on a mounting of the fastening screws from the outside. In the inner frame profiles are assigned threaded holes into which the screws are screwed. In order to prevent unauthorized manipulation from the outside, bores are introduced in the region of the screw head in the boundary region between the screw head and the protective strip, which are located partly in both the screw head and in the protective strip material. In the holes then a dowel pin is hit, which has a certain radial excess over the bore diameter and terminates flush after flushing with the top of the guard strip. In this way, unscrewing the screw is reliably prevented and as a result made disassembly of the protective strip impossible.

The third in the EP-A-1 970 523 described embodiment relates, in contrast to the first two variants no post and beam facades, but classic window or door constructions. In this case, attached to the protective strip on the inside of the building closure side facing a coupling element which extends through a slot in the outer frame profile in the interior and through a transverse to the coupling element, ie in a direction parallel to the plane of the Fill running fastener is connected to the inner or outer frame profile. This construction makes use of the fact that the glazing, ie the insertion of the fillings from the inside of the building closure, takes place in the case of window and door constructions, whereas glazed mullion-transom facades are glazed from the outside. The accessibility to the fastening screw for the protective strip is in the third embodiment only as long as the filling is not yet used. Once inserted, the filling makes accessibility to the fastener, ie, the head of the screw forming it impossible, so that the protective strip can perform its desired protective function.

In the first and the second embodiment mentioned above, there is some difficulty in mounting the fixing screws from the outside and the

Pass inside of the building closure forth through the respective frame profiles and screw with the respective opposite frame profile.

task

The invention has for its object to provide a building closure in burglar-resistant design, in which the fasteners can be mounted to secure the protective strip in a simple way and also provide a high level of security against burglary attempts.

solution

Based on a building completion of the type described above, this object is achieved in that the fasteners are also provided at a second, the inner frame profile associated end each with a second head element projecting in the radial direction over a diameter of the bolt-shaped element, so that in cooperation with a breakthrough in the inner frame profile, a positive connection between the fastening element and the inner frame profile is formed with respect to a transmission of a directed in the longitudinal direction of the bolt-shaped element tensile force, wherein the bolt-shaped element and the two head elements together form a rotationally fixed unit, so at a manipulation of the first head element in such a way that the first head element is rotated, the whole unit is rotated and a distance between the two head elements remains substantially unchanged.

The solution according to the invention is based on the recognition that it is not necessary to prevent any movement, in particular rotational movement of the bolt-shaped element, but that it is sufficient to ensure the required burglary resistance to ensure a fastening function of the fastener to the effect that removal of the protective strip is suppressed by the respective associated outer or inner frame profile. In contrast, the known solutions were based on the principle of completely fixing the fastener in its mounting position. According to the teachings of the present invention is a movement, in particular a rotational movement of the fastener in an attempted attack as long as harmless, as the attachment function can not be canceled by a positive connection both in the region of the protective strip and in the region of the inner frame profile. Under a positive connection with respect to a longitudinal force transmission is understood in the context of the present application, in particular a radial projection of the head elements on the bolt-shaped element, in conjunction with a bore diameter both in the protective strip and in the inner frame profile is smaller than the largest diameter of the respective head element. The fastener of the present invention performs its attachment function as long as the fins closing properties are maintained on both headers despite unauthorized rotational movement of the head facing the outside. By a "substantially unchanged distance" between the two head elements is to be understood that a slight elongation of the head element for functional safety is harmless, as long as there is no possibility to penetrate into a gap region between the protective strip and the outside of the filling eg with lever tools.

A particularly simple development of the invention is that the bolt-shaped element is integrally formed.

In a possible two-part design of the bolt-shaped element, this may have a sleeve which has an internally threaded portion into which an externally threaded portion of the bolt-shaped element is screwed, preferably from the sleeve, the first head element is integrally formed. The use of such threaded sleeves is therefore useful in certain applications, because in building closures with a large, measured perpendicular to the filling plane depth screws with sufficiently long length are often difficult to obtain, whereas threaded bolts of any length are easily available or produced. In order to produce a rotationally fixed unit between the bolt-shaped element and two head elements, in a multi-part embodiment of the bolt-shaped element and its individual parts must be rotatably coupled together. In the case of a combination of threaded sleeve and threaded bolt, the bolt-shaped element, in particular its outer threaded portion, can be glued or welded to the sleeve.

According to one embodiment of the invention, it is provided that the bolt-shaped element and the first head element are made in one piece in the form of a screw with a screw head, in particular a countersunk head, in particular with a hexagon socket. If the depth of the respective building completion is not too large, this is the simplest form to implement the fastener of the invention.

In order to reduce the possibility of attack on the first, the outside of the building closure facing head element, the countersunk head of the screw should be placed in a correspondingly lowered hole in the protective strip and the hexagon socket preferably be closed with a steel ball.

A particular simple way of producing a rotationally fixed connection between the bolt-shaped element and the second head element is that the latter is formed by two nuts which are screwed onto an externally threaded portion of the bolt-shaped element and locked against each other. In this way, a very simple Aufhebbarkeit the screw from the inside of the building closure is possible. As an alternative to using two lock nuts, the second head element can also be a pin or pin inserted transversely to the bolt-shaped element into a bore in the same. Between the second head element and the bore, it makes sense to arrange a washer.

Preferably, not only the fastening elements provided with the two head elements connect via the protective strips the two associated inner frame profiles. Rather, the outer frame profiles by means of other fasteners, preferably by means of screws, more preferably by means of self-tapping screws, with the respective associated inner frame profile, preferably connected to a connected to the inner frame profile on the outside of the building closure side facing screw. Such attachment corresponds to the standard attachment of the outer frame profiles to the inner frame profiles in facades, which are not subject to any safety requirements. The additional fastening elements make it possible that in the case of the fastening elements provided with two head elements according to the invention, there are no requirements for the transmission of compressive forces. So it is not necessary to transmit a greater axial pressure on the protective strips and the inner and outer frame profile over the invention, two head elements having fasteners. This function can be taken over solely by the further fastening elements explained above.

In connection with the installation of the building closure according to the invention, this results in further advantages: For example, the building completion can initially be mounted as a conventional, by the filling elements are used and fixed in place with the help of the inner frame profiles. Subsequently, bores are introduced at locations between adjacent further fastening elements which penetrate both the outer and the inner frame profile (at least its outer wall). These holes for the two head elements having fastener are introduced at a distance corresponding to the prefabricated counterbores in the protective strip. Then, the protective tape can be laid up and fastened by passing screws through the holes by attaching from the inside the second head element (e.g., two lock nuts), whereas the first head element is preferably formed by a countersunk head of the screw.

To meet the requirements of a bullet resistance, all outer frame profiles may be provided with a protective strip, or form such.

A further increase in burglary resistance can be achieved if the bolt-shaped elements are each surrounded by a sleeve, which preferably extends in the axial direction from a rear side of the outer frame profile facing an inner side of the building closure to a front side of the inner frame profile facing the outer side of the building closure and is either rotatably pressed about the bolt-shaped element or in an adapted bore in the inner frame profile or the outer frame profile. Such a sleeve leads, in particular, to an increase in the protection against attacks by means of a flat chisel through a gap region between the protective strip and the surface of the filling. In particular, when the sleeve is rotatable, it turns away under the attack force of a chisel tip.

In order to meet the requirements of the Heat Insulation Ordinance, should in the gap area between two adjacent fillings or a filling and a adjacent building part a Dämmzone be formed of a material with thermal insulation properties.

Finally, it is envisaged that the building completion is stirred in the form of a mullion-transom façade and is formed from vertically extending posts and horizontally extending bars, wherein at least the post associated outer frame profiles have the protective strips or form them, or at least the the bars associated outer frame profiles have or form the protective strips.

An in FIG. 1 imaged building closure 1 has a plurality of posts 2, which are arranged on an inner side of the building I conclusion and extend in the vertical direction. The shown comparatively small section of the building closure 1 reveals that two fillings 5, 6 are arranged between inner frame profiles 3 and outer frame profiles 4 arranged on an outside A of the building closure 1. The fillings 5, 6 are clamped by means of fastening elements 7 between mutually facing surfaces of the respective inner frame profile 3 and the outer frame profile 4.

Between the running as an extruded aluminum inner frame section 3 and inner sides 8, 9 of the fillings 5, 6 each sealing strip 10 are arranged from a rubber-elastic material. These ensure a uniform distribution of the contact pressure and thus prevent punctual overloading of the fillings 5, 6 and ensure due to the high static friction for a slip-resistant fixation of the fillings 5, 6. In the same way are located between a back 11 of the outer frame profile 4 and outsides 12, 13 of the fillings 5, 6 sealing strip 14th

The filling 5 is an insulating glass composite pane ("bulletproof glass"), which has a plurality of individual pane arrangements glued to one another on both sides of a gas-filled insulating intermediate space 15. In contrast, the filling 6 is a non-transparent panel whose outer side 13 and inner side 9 are each formed by a cover plate 16, 17. To increase the burglar-resistant effect is located on the outside of the panel adjacent to the cover plate 16, a tabular steel insert 18th

The inner frame profile 3 is provided on its side facing the outside A in a known manner with an open towards the outside A screw 19. About the screw 19 a coupling profile 20 is clipped, which serves to hold an insulating profile, which extends in a gap region 22 between opposite end faces 23, 24 and forms a Dämmzone.

The outer frame profile 4 is made of an abrasion, breakage and deformation resistant material, e.g. made of hard metal, steel or aluminum with high tensile strength and forms a burglar-resistant protective strip S. The outer frame profile 4 is insofar as a special profile as therein undercut grooves for the sealing strips 14 are arranged, as well as a lateral contouring is present a clipping of an outer cover shell 25 allows, whereby the aesthetics of the building closure 1 is designed to be appealing when viewed from the outside.

Similarly, the inner frame profile 3 has grooves for the sealing strip 10 and has on its inside a retaining profile 26, to which an inner cover shell 27 is clipped. This cover shell 27 serves to make the interior of the post 2 appealing.

The attachment of the integrally formed with the outer frame profile 4 protective strip S is carried out with a plurality of fasteners 7, which are bolt-shaped elements in the form of countersunk screws 28. The fastening element 7 has two head elements 29, 30, which are arranged at opposite ends of the fastening element 7. The head element 29 is a countersunk head of the countersunk screw 28, which is embedded in a correspondingly lowered bore in the outer frame profile 4. An outer surface of the countersunk head terminates flush with an outer surface of the outer frame profile 4. The arranged on the inside of the head element 30 is formed by two nuts 31, 32 and a washer 33. The two nuts 31, 32 are screwed onto a threaded portion 34 of the countersunk screw 28 and locked against each other. In this way, both head elements 29 and 30 and the bolt-shaped element located therebetween form a rotationally fixed unit.

In a burglary attempt, the removal of the outer cover shell 25 is possible for an attacker with simple means. Even if the attacker then rotates the countersunk head of the countersunk screw 28, for example by means of a small chisel, this does not lead to a loss of the fastening function of the fastening element 7, since the head element 30 rotates synchronously in the form of both countered nuts 31, 32 and the head element 30 thus can not be solved by the bolt-shaped element. If the attachment of the fillings 5 and 6 takes place exclusively with the aid of the fastening elements 7, that is, a certain bias for secure fixation of the fillings 5, 6 is required, it makes sense, the sliding surfaces between the support section 26 and the washer 33 and between the latter and the To provide nut 31 with a lubricant in order to keep the friction low and thus to prevent the lock of the two nuts 31, 32 can be lifted. Typically, the attachment of the fillings 5, 6 takes place in a first step, however, with the aid of shorter, in FIG. 1 not shown screws which are arranged offset to the fastening elements 7. The other fasteners preferably have a self-tapping threaded portion which is screwed into the screw 19 of the inner frame profile 3. This corresponds to the standard attachment of fillings in mullion-transom facades without safety features. In the present case, a stainless steel ball 35 is hammered into a hexagon socket of the countersunk head of the countersunk screw 28 in order to prevent the head element 29 from being drilled open and to maintain the form-fit there securely. Another advantage is that in this solution, the fasteners 7 also solve again and then 5,6 can reuse when installing a new filling, so that disassembly and assembly of the fillings 5,6 without destroying the fastener is possible.

An in FIG. 2 shown building closure 41 differs from that in FIG. 1 explained building completion 1 insofar as the inner head member 30 'is designed as a pin which is pressed into a bore in an end portion of the countersunk screw 28 without being able to move after its assembly in the axial direction. The inner frame profile 3 'is provided in this case with retaining strips 36, on which the inner cover shell 27 is clipped. The use of a separate inner holding profile as in the embodiment according to FIG. 1 is thus expendable. The mode of operation such as unauthorized dismantling of the fastener 7 at the building completion 41 according to FIG. 2 is not fundamentally different from the one previously described by means of FIG. 1 explained principle.

Basically the same applies to the in FIG. 3 shown embodiment of the building closure 51, in which the inner head member 30 "is designed as a sapwood

Head element 30 "has a loop-shaped thickening 37 at one end and two leg ends 38 spread apart in a Y-shape at the opposite end, so that slipping out of the split pin from an adapted bore in one end section of the countersunk screw is prevented.

In a building closure 61 according to FIG. 4 is the inner header 30 as in the embodiment according to FIG. 1 executed in the form of two lock nuts. However, the bolt-shaped element does not consist in this case of a continuous countersunk screws, but is divided into two parts in the form that a threaded bolt which extends from the head member 30 into the outer frame profile 4, with its the outer side A of the building closure end facing it has a male threaded portion, is screwed into a sleeve 40 having a corresponding female threaded portion and integrally formed on a countersunk head, which forms the outer head member 29. As in the case of the embodiments already described above, the sleeve 40 is inserted flush with the head element 29 in an adapted, lowered bore in the outer frame profile 4 forming the protective strip S. In a frontal hexagon socket of the sleeve 40, in turn, a stainless steel ball 35 is hammered to effect a tapping.

In addition, the threaded bolt 39 is surrounded in an area between the sleeve 40 and the inner head member 30 by an elongated steel sleeve 42. Further, in an area between a coupling profile 43, which is positively inserted into groove portions of the inner frame profile 3, and the inner side 11 of the outer frame profile 4, an insulating strip 44 made of a plastic material with good thermal insulation properties, placed in the holes and into which the steel sleeves 42 are used.

Out FIG. 4a , which shows, for example, a vertical section through a horizontally extending bolt, illustrates that the attachment of the fillings 5, 6 takes place at least in the region of the bolt exclusively with the aid of the outer frame profiles 4. In the embodiment of the building closure 61 according to the FIGS. 4 and 4a the outer frame profile 4 and the associated protective strip 5 are designed as separate components. If no bullet-resistant properties of the building 61 would be required, the Use of the protective strip S alone on two opposite edge strips of the respective filling 5, 6 sufficient to prevent unauthorized removal of the respective filling 5, 6. In this case, the protective strips S could - as in FIG. 4 shown - only be present in the area of the posts, but not in the area of the bars ( FIG. 4a ). For reasons of optical uniformity, the outer cover shell 25 in the same construction depth as in the area of the posts can also be arranged in the region of the bars.

In the region of the posts, the fixings of the fillings 5, 6 can in principle also be carried out solely with the aid of the fastening elements 7. However, it is also advantageous to screw the outer frame profiles 4 by means of further fastening elements, eg in the form of the countersunk screws 45 shown A tip section of the countersunk screws 45 is connected in a force-transmitting manner to a holding section 46 of the coupling profile 43 and / or to the screw channel 19 formed on the inner frame profile 3. Also in the area of the bars, as in FIG FIG. 4a shown - inserted between the coupling profile 43 and the inside of the outer frame profile 4, a sleeve 44 for protection purposes.

Finally shows FIG. 5 Yet another embodiment of a building closure 71, in turn, the fastening element 7 "is constructed in two parts and is composed of a sleeve 40 facing the outside A and a threaded bolt 39. In the region of the connection between the threaded bolt 39 and the sleeve 40, the two together This also applies to the embodiment according to FIG. 4 to get there also a non-rotatable unit between the two headers 29 and 30.

The variant according to FIG. 5 is particularly suitable for retrofitting a standard façade, in which commercially available outer frame profiles 4 "are used An attached coupling profile 46 extends on the one hand to the outer sides 12, 13 of the fillings 5, 6 and moreover has retaining strips 47 facing away from the fillings 5, 6 between which on the one hand the protective strip S is inserted and on the other hand serve to fasten the outer cover shell 25 'by clipping on the inside of the building closure 71 the characteristics coincide with those of the building closure 61, with the exception that in the embodiment according to FIG. 5 no elongated steel sleeve 42 is present.

Essential for the functioning of the building closures 1, 41, 51, 61, 71 according to the invention, in addition to ensuring a free rotation of the fastening elements 7, 7 ', 7 "is the fact that a sufficient mass of abrasive material in the form of the protective strip S is kept ready.

An in FIG. 6 shown once again slightly modified building completion 81 has respect to the building closure 61 according to FIG. 4 a modified so protection strip S on that the holes introduced therein have a first cylindrical portion 49, to which then a conical portion corresponding to the building closure 61 according to FIG. 4 followed. Due to the recess thus recessed, an upper side 50 of the sleeve 40 is arranged offset back relative to a surface 52 of the protective strip S, whereby the protection against tampering is further improved.

Again, in the building closure 81, the bolt-shaped element of the fastener 7 '' 'formed on the one hand by the threaded portion of the sleeve 40 and the other by a bolt portion of a screw 53 which is screwed with a threaded portion in the threaded portion of the sleeve 40 and the head of the second header 30 '' 'forms. The length of the screw 53 is dimensioned so that when the threaded portion is firmly screwed with its front side to the end of the threaded portion of the sleeve, a certain clearance 54 between the head member 30 '' 'and a washer or a surface of the coupling profile 53 remains , This clearance 54 serves as in the embodiments described above, to ensure safe untwisted manipulation of the fastener 7 '' ', without the unit of sleeve 40 and rear machine screw is released. As an alternative to the fixed screwing of the machine screw into the sleeve 40, the threaded portion of the screw can also be glued into the sleeve 40.

The last in FIG. 7 illustrated embodiment of a building closure 91 has the same protective strip with the recessed countersink as the building completion in FIG. 6 differs from the latter, however, in the form of the fastener 7 ", which in turn with the according to FIG. 4 coincides where the head member 30 is formed by two lock nuts. Again, in the hexagon socket of the sleeve 40, a stainless steel ball are hammered to serve as a tapping.
