Definitions
- the invention relates to a screw connection of mutually perpendicular hollow profiles for window, door or the like.Frames, whereby on the front end of the hollow profile, which has at least one longitudinally axially extending screw channel, a metallic connecting body with its one side laid flat and thus is to be screwed over at least one screw fastening hole in its central area and a first connecting screw to be inserted therein, and this connecting body is to be placed with its other side over a wide area on the longitudinal side of the other hollow profile and thus via screw fastening holes located at both ends and opposite to the first connecting screw the second connecting screws must be screwed tight.
- a screw connection of the above type is known from FR-A-2 287 608. It is about the T-shaped connection of a substantially rectangular cross-section, made of metal hollow profiles, with open-ended screw channels are provided on the inside in the end-to-end hollow profile on the inside of its two opposite narrow walls, each consisting of two adjacent and through a longitudinal slot separated from each other, provided on their concavely curved inner sides with corresponding thread ribs.
- the inner, penetrating the central area of the connecting body designed as countersunk screws Screw in fastening screws, while the opposite connecting screws of the connecting body are screwed into screw holes machined in the thin wall facing them of the metal profile to be connected on the long side.
- the connecting body can be designed as a flat connecting plate to be inserted between the comparatively low edges of the metal profile to be longitudinally connected or, in the case of metal profile frames provided with high edges, have a correspondingly high bump in the middle into which the central screw thread holes are incorporated.
- the metallic connecting body and the fastening screws to be installed in the opposite direction enable an easy-to-manufacture T-shaped connection of two hollow frames, which does not appear to be an external disturbance, which, however, must consist of metal because of the comparatively small fastening seat of the connecting screws.
- screw connections are known for T-shaped plastic hollow profiles to be connected to one another, in which the connecting screws to be screwed into two screw channels of the end-supported hollow profile arranged in the inner wall penetrate completely the other hollow profile, i.e. also from the long side of the hollow side facing away from the front end of the one hollow profile other profiles must be used and screwed in.
- Such a screw connection is structurally simple.
- it has the disadvantage that the two-sided attachment of the screw fastening holes in the continuous hollow profile requires an exact alignment with the screw channels of the other hollow profile to be placed at the end.
- this screw connection also leaves something to be desired in terms of strength, since the long side of the continuous hollow profile facing away from the front end of a hollow profile gives way accordingly when the connecting screws are tightened, namely bulges inwards.
- this known screw connection provided with the through hollow profile completely penetrating connecting screw is not suitable for cross-shaped hollow profile connections.
- the invention has for its object to improve a hollow profile screw connection of the type mentioned in such a way that it is particularly suitable for the T-shaped connection of plastic hollow profiles while maintaining its simple design and easy assembly and ensures a better connection strength.
- the connecting body can with a continuously flat contact surface of the longitudinally connected plastic hollow profile be designed as a flat connecting plate, which can be effortlessly installed between the hollow plastic profiles to be connected in a T-shape by means of the connecting screws to be inserted in the opposite screw fastening holes.
- the connecting body or the connecting plate also makes it possible to create cross-shaped plastic hollow profile connections, because only one such connecting body or connecting plate is provided between the opposite longitudinal sides of the hollow profile passing through and the end faces of the two other hollow profiles which are supported thereon are needed.
- transverse transverse centering projections are preferably provided which tightly encompass the front end of the plastic hollow profile in question and thereby also help to increase the connection strength.
- These centering projections are advantageously rib-shaped and have an inner wall running perpendicular to the connecting plate surface and an inclined outer wall tapering therein. With their inner wall, these centering projections or ribs, which are arranged at a corresponding distance from one another, can tightly encompass the front end of the hollow plastic profile to be placed between them and thus also act to prevent rotation, which is particularly the case when only one screw channel of the hollow profile to be connected on the front side is closed connecting screw is important.
- sealing strips of a suitable sealing material lying flat on the connecting plate can be provided between the connecting plate and the adjacent hollow profiles.
- the profile connection point shown is formed by the plastic hollow profile 2 provided with an inserted metallic reinforcement hollow profile 1 and passing through at the connection point on the one hand and the plastic hollow profile 3 to be screwed on the end face thereof, which according to FIG. 2 is arranged with several, preferably two, on its inner wall opposite one another , longitudinal axially extending, all around closed screw channels 4 is provided.
- the connection between the two hollow profiles 2, 3 takes place via the metallic screw connection body 5, which is made, for example, of stainless steel but also of light metal, such as e.g. a suitable aluminum alloy. Since the plastic hollow profile 2 to be connected on the longitudinal side has a continuously flat supporting surface 2 'for the connecting body 5 to be placed thereon, the latter is advantageously designed here as a flat connecting plate.
- the connecting plate 5 is in the present case specifically of the nature shown in FIGS. 3 and 4. It has two screw fastening holes 6 on the inside for the connecting screws 7 to be inserted therein, which are to be screwed into the all-round screw channels 4 of the hollow section 3, and two screw fastening holes 8 at their ends 5 ', i.e. outside screw fastening holes 8 for the continuous hollow section 2 and the metallic one therein Reinforcement profile 1 to be inserted or screwed in connecting screws 9.
- the connecting plate 5 On its upper side facing the hollow profile 3 lying at the end, the connecting plate 5 is provided with transversely running, rib-shaped centering projections 10, each of which has an inner wall 10 'running perpendicular to the plate surface and an inclined outer wall 10''tapering therein. With these centering ribs 10, the connecting plate 5 can tightly encompass the end face 3 'of the hollow profile 3. In its central part 5 ′′, which lies within the centering ribs 10 and has the inner screw fastening holes 6, the plate 5 projects over its ends 5 ′ on both sides in order to fully correspond in profile to the hollow profile 3 to be placed on the end face.
- a lower and upper sealing strip 11 or 12 are preferably inserted, so that no water from the outside into the screw connection point formed and over it in the profile interiors can enter.
- the screw connection plate 5 together with the sealing layer 12 lying on its upper side is first fastened to the front end 3 'of the hollow profile 3 via the internal screws 7 to be screwed into the screw channels 4 which are closed all around.
- the connecting plate 5 with the lower sealing layer 11 with the hollow profile 3 can then be placed on the continuous hollow profile 2 and can be firmly connected to it by means of the external connecting screws 9.
- the same principle of connection is also used for the construction of cross-shaped hollow profile connections.

Abstract
Description
Die Erfindung betrifft eine Schraubverbindung von rechtwinklig zueinander verlaufenden Hohlprofilen für Fenster-, Tür- od. dgl. Rahmen, wobei auf das Stirnende des einen, in seinem Inneren mindestens einen längsaxial verlaufenden Schraubkanal aufweisenden Hohlprofils ein metallischer Verbindungskörper mit seiner einen Seite flach aufzulegen und damit über mindestens ein in seinem mittleren Bereich vorhandenes Schraubbefestigungsloch und eine darin einzusetzende erste Verbindungsschraube zu verschrauben ist und dieser Verbindungskörper mit seiner anderen Seite breitflächig auf die Längsseite des anderen Hohlprofils aufzulegen und damit über an seinen beiden Enden gelegene Schraubbefestigungslöcher und darin einzusetzende, entgegengesetzt zur ersten Verbindungsschraube gerichtete zweite Verbindungsschrauben fest zu verschrauben ist.The invention relates to a screw connection of mutually perpendicular hollow profiles for window, door or the like.Frames, whereby on the front end of the hollow profile, which has at least one longitudinally axially extending screw channel, a metallic connecting body with its one side laid flat and thus is to be screwed over at least one screw fastening hole in its central area and a first connecting screw to be inserted therein, and this connecting body is to be placed with its other side over a wide area on the longitudinal side of the other hollow profile and thus via screw fastening holes located at both ends and opposite to the first connecting screw the second connecting screws must be screwed tight.
Eine Schraubverbindung obiger Art ist durch die FR-A-2 287 608 bekannt. Es geht dabei um die T-förmige Verbindung von einen im wesentlichen rechteckigen Querschnitt aufweisenden, aus Metall bestehenden Hohlprofilen, wobei im stirnendig zu verbindenden Hohlprofil auf der inneren Seite seiner beiden gegenüberliegenden Schmalwände innenseitig offene Schraubkanäle vorgesehen sind, die jeweils aus zwei nebeneinander verlaufenden und durch einen Längsschlitz voneinander getrennten, an ihren konkav zueinander gekrümmten Innenseiten mit entsprechendem Gewinde versehenen Gewinderippen bestehen. In diese sind die den mittleren Bereich des Verbindungskörpers durchdringenden, als Senkkopfschrauben ausgebildeten inneren Befestigungsschrauben einzudrehen, während die dazu entgegengesetzt gerichteten äußeren Verbindungsschrauben des Verbindungskörpers in in der ihnen zugewandten dünnen Wandung des längsseitig zu verbindenden Metallprofils eingearbeitete Schraubgewindelöcher einzudrehen sind. Der Verbindungskörper kann dabei als zwischen den vergleichsweise niedrig gehaltenen Rändern des längszuverbindenden Metallprofils einzulegende flache Verbindungsplatte ausgebildet sein oder aber bei mit hohen Rändern versehenen Metallprofilrahmen mittig einen entsprechend hohen Höcker aufweisen, in den die mittleren Schraubgewindelöcher eingearbeitet sind. Der metallische Verbindungskörper und die in ihm entgegengesetzt gerichtet anzubringenden Befestigungsschrauben ermöglichen eine leicht herzustellende und noch dazu äußerlich nicht störend in Erscheinung tretende T-förmige Verbindung zweier Hohlrahmen, die dafür jedoch allein schon wegen des vergleichsweise geringen Befestigungssitzes der Verbindungsschrauben hier aus Metall bestehen müssen.A screw connection of the above type is known from FR-A-2 287 608. It is about the T-shaped connection of a substantially rectangular cross-section, made of metal hollow profiles, with open-ended screw channels are provided on the inside in the end-to-end hollow profile on the inside of its two opposite narrow walls, each consisting of two adjacent and through a longitudinal slot separated from each other, provided on their concavely curved inner sides with corresponding thread ribs. In these are the inner, penetrating the central area of the connecting body, designed as countersunk screws Screw in fastening screws, while the opposite connecting screws of the connecting body are screwed into screw holes machined in the thin wall facing them of the metal profile to be connected on the long side. The connecting body can be designed as a flat connecting plate to be inserted between the comparatively low edges of the metal profile to be longitudinally connected or, in the case of metal profile frames provided with high edges, have a correspondingly high bump in the middle into which the central screw thread holes are incorporated. The metallic connecting body and the fastening screws to be installed in the opposite direction enable an easy-to-manufacture T-shaped connection of two hollow frames, which does not appear to be an external disturbance, which, however, must consist of metal because of the comparatively small fastening seat of the connecting screws.
Im Gegensatz hierzu sind für T-förmig miteinander zu verbindende Kunststoff-Hohlprofile Schraubverbindungen bekannt, bei denen die in zwei innenwandseitig angeordnete Schraubkanäle des stirnendig sich abstützenden Hohlprofils einzudrehenden Verbindungsschrauben das andere Hohlprofil vollständig durchdringen, also auch von der dem Stirnende des einen Hohlprofils abgewandten Längsseite des anderen Profils her eingesetzt und eingedreht werden müssen. Eine solche Schraubverbindung ist zwar baulich einfach. Sie hat jedoch den Nachteil, daß die beidseitige Anbringung der Schraubbefestigungslöcher in dem durchlaufenden Hohlprofil eine exakte Ausrichtung zu den Schraubkanälen des stirnendig aufzusetzenden anderen Hohlprofils erfordert. Außerdem läßt diese Schraubverbindung aber auch an Festigkeit zu wünschen übrig, da die dem Stirnende des einen Hohlprofils abgewandte Längsseite des durchlaufenden Hohlprofils beim Anziehen der Verbindungsschrauben entsprechend nachgibt, sich nämlich nach innen wölbt. Das ist auch dann der Fall, wenn der durchlaufende Hohlprofilstab mit einem einliegenden metallischen Verstärkungshohlprofil versehen ist, da dieses regelmäßig nicht breitflächig an der Innenwandung des Hohlprofils, sondern lediglich an einzelnen Innenwandungsrippen des Hohlprofils anliegt und daher dem Anziehen der Verbindungsschrauben keinen hinreichend festen Widerstand entgegenzusetzen vermag. Schließlich ist diese bekannte, mit das durchgehende Hohlprofil vollständig durchdringenden Verbindungsschrauben versehene Schraubverbindung auch nicht für kreuzförmige Hohlprofil-Verbindungen geeignet.In contrast to this, screw connections are known for T-shaped plastic hollow profiles to be connected to one another, in which the connecting screws to be screwed into two screw channels of the end-supported hollow profile arranged in the inner wall penetrate completely the other hollow profile, i.e. also from the long side of the hollow side facing away from the front end of the one hollow profile other profiles must be used and screwed in. Such a screw connection is structurally simple. However, it has the disadvantage that the two-sided attachment of the screw fastening holes in the continuous hollow profile requires an exact alignment with the screw channels of the other hollow profile to be placed at the end. In addition, this screw connection also leaves something to be desired in terms of strength, since the long side of the continuous hollow profile facing away from the front end of a hollow profile gives way accordingly when the connecting screws are tightened, namely bulges inwards. This is also the case when the continuous hollow profile rod is provided with an inserted metallic reinforcing hollow profile, since this does not regularly cover the inner wall of the hollow profile, but rather only on individual inner wall ribs of the hollow profile and is therefore unable to oppose the tightening of the connecting screws with a sufficiently firm resistance. Finally, this known screw connection provided with the through hollow profile completely penetrating connecting screw is not suitable for cross-shaped hollow profile connections.
Der Erfindung liegt die Aufgabe zugrunde, eine Hohlprofil-Schraubverbindung der eingangs erwähnten Gattung dahingehend zu verbessern, daß sie unter Beibehalt ihrer einfachen Bauart und leichten Montierbarkeit speziell auch für die T-förmige Verbindung von Kunststoff-Hohlprofilen geeignet ist und dafür eine bessere Verbindungsfestigkeit gewährleistet.The invention has for its object to improve a hollow profile screw connection of the type mentioned in such a way that it is particularly suitable for the T-shaped connection of plastic hollow profiles while maintaining its simple design and easy assembly and ensures a better connection strength.
Diese Aufgabe wird ausgehend von einer Schraubverbindung der eingangs beschriebenen Gattung erfindungsgemäß dadurch gelöst, daß die miteinander schraubzuverbindenden Hohlprofile aus Kunststoff bestehen, der im stirnendig zu verbindenden Kunststoff-Hohlprofil vorhandene Schraubkanal ringsum geschlossen ist und im längsseitig zu verbindenden Kunststoff-Hohlprofil ein metallisches Verstärkungs-Hohlprofil eingeschoben ist, in das die beiden endseitig im Verbindungskörper sitzenden zweiten Verbindungsschrauben einzuschrauben sind. Auf diese Weise kommt man zu einer auch bei der T-förmigen Verbindung von Kunststoff-Hohlprofilen hinreichend festen Schraubverbindung, wofür einerseits die ringsum geschlossene Ausbildung des oder der im Inneren des stirnendig zu verbindenden Kunststoff-Hohlprofils vorhandenen Schraubkanäle sorgt und andererseits das im längsseitig zu verbindenden Kunststoff-Hohlprofil vorhandene metallische Verstärkungs-Hohlprofil beiträgt, da in beide die entsprechenden Verbindungsschrauben hinreichend fest eingedreht bzw. eingeschraubt werden können. Die bei der Verwendung von Kunststoff als Hohlprofil-Werkstoff nie ganz zu vermeidende geringfügige Flexibilität des Kunststoffs ist dabei ohne Belang, da in beiden Fällen ein hinreichend fester Befestigungssitz der Verbindungsschrauben gewährleistet ist.This object is achieved on the basis of a screw connection of the type described at the outset in that the hollow profiles to be screwed together are made of plastic, the screw channel present in the end-to-end plastic hollow profile is closed all around and a metallic reinforcing hollow profile in the plastic hollow profile to be connected on the longitudinal side is inserted into which the two second connecting screws located at the end in the connecting body are to be screwed. In this way, one obtains a sufficiently firm screw connection even in the case of the T-shaped connection of plastic hollow profiles, which is ensured on the one hand by the all-round closed design of the screw channels present inside the plastic hollow profile to be connected at the end face, and on the other hand that to be connected in the longitudinal direction Plastic hollow profile existing metallic reinforcement hollow profile contributes, since in both the corresponding connecting screws can be screwed in or screwed in sufficiently firmly. The slight flexibility of the plastic, which can never be completely avoided when using plastic as a hollow profile material, is irrelevant, since in both cases a sufficiently firm fastening fit of the connecting screws is ensured.
Der Verbindungskörper kann bei durchgehend plan verlaufender Auflagefläche des längsseitig zu verbindenden Kunststoff-Hohlprofils als flache Verbindungsplatte ausgebildet sein, die über die in ihre Schraubbefestigungslöcher entgegengesetzt einzusetzenden Verbindungsschrauben mühelos zwischen den miteinander T-förmig zu verbindenden Kunststoff-Hohlprofilen montiert werden kann.The connecting body can with a continuously flat contact surface of the longitudinally connected plastic hollow profile be designed as a flat connecting plate, which can be effortlessly installed between the hollow plastic profiles to be connected in a T-shape by means of the connecting screws to be inserted in the opposite screw fastening holes.
Der Verbindungskörper bzw. die Verbindungsplatte ermöglicht es aber auch, kreuzförmige Kunststoff-Hohlprofil-Verbindungen zu schaffen, weil dazu lediglich je ein solcher Verbindungskörper bzw. Verbindungsplatte zwischen den gegenüberliegenden Längsseiten des hindurchgehenden Hohlprofils und den sich darauf gegenüberliegend abstützenden Stirnenden der beiden anderen Hohlprofile vorgesehen zu werden braucht.The connecting body or the connecting plate also makes it possible to create cross-shaped plastic hollow profile connections, because only one such connecting body or connecting plate is provided between the opposite longitudinal sides of the hollow profile passing through and the end faces of the two other hollow profiles which are supported thereon are needed.
Auf der dem stirnendig aufliegenden Kunststoff-Hohlprofil zugewandten Oberseite des Verbindungskörpers sind vorzugsweise noch quer verlaufende Zentriervorsprünge vorgesehen, die das Stirnende des betreffenden Kunststoff-Hohlprofils eng umgreifen und dadurch zugleich auch noch die Verbindungsfestigkeit zu steigern helfen. Diese Zentriervorsprünge sind vorteilhaft rippenförmig ausgebildet und besitzen eine senkrecht zur Verbindungsplattenoberfläche verlaufende Innenwandung sowie eine darin scharfkantig auslaufende schräge Außenwandung. Mit ihrer Innenwandung können diese in entsprechendem Abstand voneinander angeordneten Zentriervorsprünge bzw. -rippen das Stirnende des zwischen ihnen aufzusetzenden Kunststoff-Hohlprofils eng umgreifen und dadurch auch verdrehungssichernd wirken, was insbesondere beim Vorhandensein nur einer in den entsprechenden, ringsum geschlossenen Schraubkanal des stirnseitig zu verbindenden Hohlprofils einzudrehenden Verbindungsschraube wichtig ist.On the front side of the plastic hollow profile facing the top of the connecting body transverse transverse centering projections are preferably provided which tightly encompass the front end of the plastic hollow profile in question and thereby also help to increase the connection strength. These centering projections are advantageously rib-shaped and have an inner wall running perpendicular to the connecting plate surface and an inclined outer wall tapering therein. With their inner wall, these centering projections or ribs, which are arranged at a corresponding distance from one another, can tightly encompass the front end of the hollow plastic profile to be placed between them and thus also act to prevent rotation, which is particularly the case when only one screw channel of the hollow profile to be connected on the front side is closed connecting screw is important.
Um die Schraubverbindungsstellen zwischen den über die Verbindungsplatte miteinander zu verbindenden Hohlprofilen gegen eindringende Feuchtigkeit wirksam abzudichten, können zwischen der Verbindungsplatte und den anliegenden Hohlprofilen flach auf der Verbindungsplatte aufliegende Abdichtungsstreifen aus geeignetem Dichtungswerkstoff vorgesehen sein.In order to effectively seal the screw connection points between the hollow profiles to be connected to one another via the connecting plate against ingress of moisture, sealing strips of a suitable sealing material lying flat on the connecting plate can be provided between the connecting plate and the adjacent hollow profiles.

Die dargestellte Profilverbindungsstelle wird von dem mit einem eingesetzten metallischen Verstärkungshohlprofil 1 versehenen, an der Verbindungsstelle durchlaufenden Kunststoff-Hohlprofil 2 einerseits und dem darauf stirnendig zu verschraubenden Kunststoff-Hohlprofil 3 gebildet, das entsprechend Fig.2 mit mehreren, vorzugsweise zwei an seiner Innenwand gegenüberliegend angeordneten, längsaxial verlaufenden, jeweils ringsum geschlossenen Schraubkanälen 4 versehen ist. Die Verbindung zwischen den beiden Hohlprofilen 2,3 erfolgt über den metallischen Schraubverbindungskörper 5, der beispielsweise aus nicht rostendem Stahl aber auch aus Leichtmetall, wie z.B. einer geeigneten Aluminiumlegierung, bestehen kann. Da das längsseitig zu verbindende Kunststoff-Hohlprofil 2 eine durchgehend plan verlaufende Auflagefläche 2' für den auf ihr aufzulegenden Verbindungskörper 5 besitzt, ist letzterer hier vorteilhaft als flache Verbindungsplatte ausgebildet.The profile connection point shown is formed by the plastic
Die Verbindungsplatte 5 ist im vorliegenden Falle speziell von der in den Fig.3 und 4 dargestellten Beschaffenheit. Sie besitzt je zwei innenliegende Schraubbefestigungslöcher 6 für die darin einzusetzenden, in die ringsum geschlossenen Schraubkanäle 4 des Hohlprofils 3 einzudrehenden Verbindungsschrauben 7 und zwei in ihren Enden 5', also außen liegende Schraubbefestigungslöcher 8 für die in das durchlaufende Hohlprofil 2 und das darin vorhandene, metallische Verstärkungsprofil 1 einzusetzenden bzw. einzudrehenden Verbindungsschrauben 9. Als Verbindungsschrauben 7,9 dienen vorzugsweise selbstschneidende Senkkopfschrauben, die mit ihren Köpfen an den entgegengesetzt konisch verlaufenden Begrenzungswandungen der inneren und äußeren Schraubbefestigungslöcher 6 bzw. 8 fest anliegen. Auf ihrer dem stirnendig aufliegenden Hohlprofil 3 zugewandten Oberseite ist die Verbindungsplatte 5 mit quer verlaufenden, rippenförmigen Zentriervorsprüngen 10 versehen, die jeweils eine senkrecht zur Plattenoberfläche verlaufende Innenwandung 10' und eine darin scharfkantig auslaufende schräge Außenwandung 10'' besitzen. Mit diesen Zentrierrippen 10 kann die Verbindungsplatte 5 das Stirnende 3' des Hohlprofils 3 eng umgreifen. In ihrem innerhalb der Zentrierrippen 10 liegenden, die inneren Schraubbefestigungslöcher 6 aufweisenden Mittelteil 5'' springt die Platte 5 beidseitig über ihre Enden 5' vor, um auch insoweit dem darauf stirnendig aufzusetzenden Hohlprofil 3 profilmäßig voll zu entsprechen.The connecting
Zwischen der Schraubverbindungsplatte 5 und den an ihr unter- und oberseitig anliegenden Kunststoff-Hohlprofilen 2 bzw. 3 sind vorzugsweise noch je ein unterer und oberer Dichtungsstreifen 11 bzw. 12 eingelegt, so daß von außen kein Wasser in die so gebildete Schraubverbindungsstelle und über sie in die Profil-Innenräume gelangen kann.Between the
Zur Montage der T-förmigen Hohlprofil-Verbindung wird zunächst die Schraubverbindungsplatte 5 mitsamt der auf ihrer Oberseite aufliegenden Dichtungsschicht 12 über die in die ringsum geschlossenen Schraubkanäle 4 einzudrehenden, innenliegenden Schrauben 7 am Stirnende 3' des Hohlprofils 3 befestigt. Sodann kann die Verbindungsplatte 5 mit der unteren Dichtungsschicht 11 mit dem Hohlprofil 3 auf das durchlaufende Hohlprofil 2 aufgesetzt und mittels der außenliegenden Verbindungsschrauben 9 damit fest verbunden werden. Die prinzipiell gleiche Verbindungsweise wird auch für die Errichtung kreuzförmiger Hohlprofilverbindungen verwendet. Dazu wird je eine metallische Verbindungsplatte 5 zwischen deren gegenüberliegenden Längsseiten des hindurchgehenden Hohlprofils, z.B. 2, und den sich darauf gegenüberliegend abstützenden Stirnenden 3' der beiden anderen Hohlprofile 3 vorgesehen. Da die Enden 5' der Verbindungsplatte 5 mitsamt den in ihnen liegenden Senkköpfen 9' der Verbindungsschrauben 9 äußerlich kaum in Erscheinung treten, wird dadurch das Äußere dieser Kunststoff-Hohlprofil-Verbindung praktisch nicht beeinträchtigt, insbesondere dann nicht, wenn die Verbindungsplatten 5 etwa mit einem den über sie miteinander zu verbindenden Kunststoff-Hohlprofilen entsprechenden Farbüberzug versehen werden.To assemble the T-shaped hollow profile connection, the
