This application claims the priority of German Patent Application Serial No. DE 20 2007 001 653.0, filed Jan. 31, 2007, pursuant to 35 U.S.C. 119(a)-(d), the subject matter of which is incorporated herein by reference.
The present invention relates to a structural terminus implemented to limit explosive effects and relates in particular to a structural terminus of the type which includes at least two panel elements and a frame element situated in a gap area between the panel elements, which encloses each of the two panel elements together with further frame elements, where the frame element situated in the gap area are assembled from external and internal frame profiles.
A structural terminus in the meaning of the present application is a window, a door, or another planar terminus element. The structural terminus may be openable or permanently closed and may be provided with a transparent or opaque panel. Generally known structural termini which form the species are particularly so-called window façades.
The present invention is embodied in a structural terminus having desirable and advantageous features of an improved structural terminus to obviate prior art shortcomings and in particular, to provide a significant stiffening to the structural terminus which also has a significantly better stabilization effect.
According to one aspect of the present invention, the structural terminus implemented to limit explosive effect includes at least two panel elements and a frame element situated in a gap area between the panel elements, which, together with further frame elements encloses each of the two panel elements the frame element situated in the gap area being assembled from an external frame profile which is situated outside the plane defined by the exterior sides of the panel elements and an internal frame profile running parallel thereto, which is situated inside the plane defined by the interior sides of the panel elements at least one insulating profile being situated between the two frame profiles and an adapter profile being situated in front of the external frame profile on the outside or the internal frame profile on the inside, wherein the adapter profile is connected to the frame profile opposite thereto using connecting elements which are situated distributed in its longitudinal direction and pass through the area of the at least one insulating profile.
Another feature of the present invention is that the adapter profile is connected to the frame profile opposite thereto using connecting elements which are situated distributed in its longitudinal direction and pass through the area of the at least one insulating profile. The connection of the adapter profile to the opposing frame profile results in significant stiffening of the structural terminus in an especially simple way. In particular, according to the present invention, the particular other frame profile contributes significantly better to the stabilization effect than in the prior art, in that the insulating profile, which always forms a weak point in regard to the strength, is more or less bypassed and/or reinforced by the connecting elements. The thermal separating effect of the insulating profile is maintained as much as possible by the connecting elements, which are only provided punctually.
The connecting elements of a structural terminus according to the present invention are preferably connected to a reinforcement profile situated in the interior of the external frame profile. The structural terminus is stiffened further by the connection to a reinforcement profile in the internal frame profile.
The adapter profile of a structural terminus according to the present invention is especially preferably assembled from a reinforcement profile and a mantle profile which covers it on the exterior. The use of a reinforcement profile also causes further stiffening of the structural terminus here, the covering mantle profile being able to be adapted especially easily to the desired visual appearance of the structural terminus as a separate module.
The mantle profile is advantageously fastened to a retention profile, in particular clipped thereon, the retention profile being connected to the external or internal frame profile. The use of a separate retention profile (instead of integrating a retention unit for the mantle profile in the affected frame profile) allows the use of the particular frame profile without mantle profile or different frame profiles with the same mantle profiles in a building block system as well as the subsequent add-on of a mantle profile to an existing frame profile.
Furthermore, it is advantageous if the internal and/or external reinforcement profile of a structural terminus according to the present invention is a hollow profile, in particular a rectangular profile. The particular reinforcement profile then has an improved ratio of the rigidity to mass and material used in relation to a solid profile.
The external and internal frame profiles of a structural terminus according to the present invention are preferably connected to one another via insulating webs and the connecting elements run in an intermediate space between the insulating webs. The insulating webs ensure a thermal separation of the internal and external frame profiles.
The connecting elements of a structural terminus according to the present invention are advantageously screws or bolts. In relation to the alternative use of cast connecting elements, the structural terminus according to the present invention may be implemented more cost-effectively by using standard and mass-produced parts.
These screws or bolts are preferably guided from the exterior side of the structural terminus through holes in the external reinforcement profile and the external frame profile and screwed into a threaded hole in the interior reinforcement profile. These screws or bolts are thus not visible on the interior side of the structural terminus.
Furthermore, the external frame profile implemented as a hollow profile is preferably provided with an insert, which covers edge strips of the neighboring panel elements on both sides. The security of the structural terminus against break-ins is thus increased. The security against penetrating gunshots and explosive effect is improved, in particular if the insert is made of steel.
This insert advantageously extends over a joint between the frame element located in the gap area and at least one adjoining frame element through a recess in a lateral face of the adjoining frame element into the latter. The structural terminus is further stiffened by this overlap of the insert into the adjoining frame element.
Furthermore, on a structural terminus according to the present invention, an external reinforcement profile located in the adapter profile preferably extends on at least one side beyond the external outline of a screen frame formed by frame elements, is supported on a visible side of a structural part, and is preferably anchored there. The structural terminus is also improved further in its stability by the overlap of the reinforcement profile and the support on the exterior side of the structural part, because large forces may be introduced into the affected structural part in this way.
The reinforcement profile of a structural terminus according to the present invention located in the adapter profile is especially advantageously connected on at least one end to a soffit of the structural part by anchors. The structural terminus is also stiffened further by the anchoring of the external reinforcement profile—instead of only support.
The connection between this reinforcement profile located in the adapter profile on one hand and the structural part on the other hand preferably allows a displacement of the structural terminus, in particular the adapter profile, in a direction perpendicular to the plane of the panel elements. The connection allows an elastic and/or plastic deformation of the structural part under a pressure wave.
Such a displacement in the area of the connection between the reinforcement profile in the adapter profile and the structural part also advantageously causes energy consumption, in particular via component deformation and/or via friction. The displacement may thus dissipate at least a part of the energy content of a pressure wave impinging the structural terminus.
Advantageously, this connection between the external reinforcement profile in the anchoring element and the adapter profile has an oblong hole-bolt combination. Such a connection may thus be implemented especially simply.
In a further advantageous embodiment, at least one of the panel elements of a structural terminus according to the present invention is openable. In particular, such an openable panel element may be attached to the frame element so it is pivotable and/or tiltable. The panel element may be implemented as frameless for this purpose or have a generally known casement.
