Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Balkons oder einer Terrasse in situ, wobei zunächst eine untere Schalplatte und mindestens eine seitliche Stirnschalung bereitgestellt werden, um flüssigen Beton aufzunehmen.The invention relates to a method for producing a balcony or a terrace in situ, wherein initially a lower formwork panel and at least one lateral end formwork are provided to receive liquid concrete.

Die Herstellung von Gebäuden unterliegt ständig steigenden Qualitäts- und Sicherheitsanforderungen. Darüber hinaus besteht durch den vorherrschenden Kostendruck ein hoher Bedarf nach einfachen und effizienten Verfahren zur Herstellung von Gebäuden und deren Einzelteilen, sowie nach Bauelementen die einen raschen und kostengünstigen Baufortschritt ermöglichen.The manufacturing of buildings is subject to constantly increasing quality and safety requirements. In addition, there is a high demand for simple and efficient processes for the manufacture of buildings and their individual parts, as well as for components that allow rapid and cost-effective construction progress due to the prevailing cost pressure.

Insbesondere ist die Herstellung von Balkonen und Terrassen nach wie vor nicht vollständig befriedigend gelöst. Üblicherweise werden Balkone hergestellt, indem eine Schalung hergestellt wird, die zunächst die erforderliche Bewehrung und daran anschließend der flüssige Beton eingebracht wird. Wasserablaufrinnen können hergestellt werden, indem die Schalung entsprechend modifiziert wird. Um eine Stützkonstruktion für ein Geländer einer Verglasung oder dergleichen anzubringen, ist es erforderlich, Bohrungen einzubringen und Öffnungen zu schaffen, die in der Folge wieder verschlossen werden müssen. Dabei kann das Austreten von Wasser nur durch eine entsprechende Abdichtung verhindert werden, um unschöne Wasserablaufspuren auf der Sichtseite zu vermeiden. Erfahrungsgemäß gelingt es in vielen Fällen nicht, diese Abdichtung zuverlässig herzustellen und überdies altern die Dichtelemente im Zeitablauf, so dass immer wieder Baumängel auftreten, die zu Reklamationen und zu aufwendigen Nachbesserungen führen.In particular, the production of balconies and terraces is still not completely satisfactorily solved. Usually balconies are made by a formwork is made, which is first introduced the required reinforcement and then the liquid concrete. Drainage channels can be made by modifying the formwork accordingly. In order to provide a support structure for a railing of a glazing or the like, it is necessary to introduce holes and create openings that must be closed again in the sequence. In this case, the leakage of water can only be prevented by an appropriate seal to avoid unsightly traces of water drainage on the visible side. Experience has shown that it is not possible in many cases to reliably produce this seal and, moreover, the sealing elements age over time, so that again and again building defects occur that lead to complaints and to costly rework.

In der DE 33 31 434 ist ein Verfahren zum Montieren von Balkonen beschrieben. Die Befestigungsmittel für das Balkongeländer werden dabei an der Außenseite des Balkons eingebracht, wodurch sich die oben beschriebenen Nachteile ergeben.In the DE 33 31 434 a method of mounting balconies is described. The fastening means for the balcony railing are thereby introduced on the outside of the balcony, resulting in the disadvantages described above.

Weiters beschreibt die WO 94/25696 ein Profil für die Herstellung eines Balkons, das eine Wasserablaufrinne beinhaltet. Dieses Aluminiumprofil wird bei der Herstellung des Balkons in den Beton eingegossen und beinhaltet eine Wasserablaufrinne sowie Befestigungsstellen für eine Stützkonstruktion. Die Sichtfläche des Balkons ist dabei stets durch das Aluminiumprofil vorgegeben, was in vielen Fällen aus architektonischen Gründen nicht erwünscht ist. Darüber hinaus sind die zulässigen Kräfte und Momente, die von der Stützkonstruktion auf das Profil übertragen werden dürfen, begrenzt, da die entsprechenden Hebelarme für die Kraftübertragung klein sind. Wenn jedoch das Profil ausreichend robust und schwer ausgeführt wird, um die auftretenden Kräfte aufnehmen zu können, so ergibt sich eine entsprechend aufwendige und kostenintensive Lösung.Further describes the WO 94/25696 a profile for making a balcony that includes a drainage channel. This aluminum profile is poured into the concrete during the manufacture of the balcony and includes a water drainage channel and attachment points for a support structure. The visible surface of the balcony is always given by the aluminum profile, which is not desirable in many cases for architectural reasons. In addition, are the permissible forces and moments that may be transmitted from the support structure to the profile are limited because the corresponding lever arms for power transmission are small. However, if the profile is sufficiently robust and heavy to be able to absorb the forces occurring, so there is a correspondingly complex and costly solution.

Aufgabe der Erfindung ist es, diese Nachteile zu vermeiden und ein Verfahren anzugeben, das einfach und sicher in der Anwendung ist. Dabei soll die Gefahr von Schäden durch Unachtsamkeit auf der Baustelle oder dergleichen soweit wie möglich verringert werden. Eine weitere Aufgabe der Erfindung ist es, ein Verfahren anzugeben, das eine sichere und robuste Anbringung von Haltekonstruktionen ermöglicht.The object of the invention is to avoid these disadvantages and to provide a method which is simple and safe in the application. The risk of damage due to carelessness on the construction site or the like should be reduced as much as possible. Another object of the invention is to provide a method which allows a secure and robust attachment of support structures.

Darüber hinaus ist es eine Aufgabe der Erfindung, einen Betonfertigteil, sowie ein Betonfertigteilsystem anzugeben, mit dem ein solches Verfahren effizient ausgeführt werden kann.Moreover, it is an object of the invention to provide a precast concrete element, as well as a precast concrete system, with which such a method can be carried out efficiently.

Erfindungsgemäß werden diese Aufgaben dadurch gelöst, dass eine erste Stirnschalung als Betonfertigteil ausgebildet ist, der eine Wasserablaufrinne aufweist und eine Haltekonstruktion im Bereich der Wasserablaufrinne befestigt wird.According to the invention, these objects are achieved in that a first end formwork is designed as a precast concrete part, which has a water drainage channel and a support structure is fastened in the region of the water drainage channel.

Mit der erfindungsgemäßen Lösung werden verschiedenen Aufgaben gleichzeitig in vorteilhafter Weise gelöst. Zum einen ist die Sichtfläche des Balkons bzw. der Terrasse eine fabriksmäßig hergestellte Betonoberfläche und somit von hoher optischer Qualität, zum anderen ist die Herstellung wesentlich vereinfacht, da keine gesonderte Stirnschalung erforderlich ist und keinerlei zusätzliche Maßnahmen zur Herstellung der Wasserablaufrinne erforderlich sind.With the solution according to the invention various tasks are simultaneously solved in an advantageous manner. On the one hand, the visible surface of the balcony or the terrace is a factory-made concrete surface and thus of high optical quality, on the other hand, the production is much easier because no separate front formwork is required and no additional measures to produce the water gutter are required.

Die Herstellung kann insbesondere dadurch weiter vereinfacht werden, dass weitere Stirnschalungen verwendet werden, die als Betonfertigteile ausgebildet sind und die Seitenflächen des Balkons oder der Terrasse bilden. Wenn man beispielsweise von einem rechteckigen Balkon ausgeht, der vollständig von einer Gebäudefassade vorragt, so wird die zur Gebäudefassade parallele Stirnfläche des Balkons durch die erste Stirnschalung ausgebildet, und die weiteren Stirnschalungen bilden die zur Gebäudefassade senkrechten Seitenflächen des Balkons aus. Zur Herstellung des Balkons ist daher nur noch eine untere Schalplatte erforderlich, die die Unterseite des Balkons definiert. Im Fall einer Terrasse ist in vielen Fällen überhaupt kein zusätzliches Schalungselement erforderlich.The production can be further simplified in particular by using further front formworks, which are designed as precast concrete elements and form the side surfaces of the balcony or the terrace. For example, assuming a rectangular balcony projecting entirely from a building facade, the front face of the balcony parallel to the building facade is formed by the first front formwork, and the further formwork forms the side surfaces of the balcony perpendicular to the building facade. For the preparation of the balcony, therefore, only a lower formwork panel is required, which defines the underside of the balcony. In the case of a terrace in many cases no additional formwork element is required.

Ein besonders einfacher Arbeitsfortschritt ist gegeben, wenn die Oberfläche des Balkons oder der Terrasse gebildet wird, indem der flüssige Beton unter Verwendung von geneigten Abzugsflächen an den weiteren Stirnschalungen abgezogen wird. Auf diese Weise ist die Herstellung eines Balkons oder einer Terrasse besonders kostengünstig möglich.A particularly simple work progress is given when the surface of the balcony or the terrace is formed by the liquid concrete withdrawn using inclined Abzugsflächen on the other front formworks becomes. In this way, the production of a balcony or a terrace is particularly inexpensive possible.

Eine Verschmutzung der Wasserablaufrinne und damit erforderliche Nacharbeiten können in vorteilhafter Weise dadurch verhindert werden, dass beim Einbringen und Abziehen des Betons die Wasserablaufrinne verschlossen wird.Contamination of the water drainage channel and thus required rework can be advantageously prevented by the fact that the water drainage channel is closed during introduction and removal of the concrete.

Eine besonders begünstigte Ausführungsvariante des erfindungsgemäßen Verfahrens sieht vor, dass vor dem Einbringen des Betons mindestens ein Anker zur Anbringung einer Haltekonstruktion eingelegt wird, der sich in der Wasserablaufrinne abstützt und teilweise in den Beton eingegossen wird. Ein besonderer Vorteil dieser Ausführungsvariante liegt darin, dass eine sichere Verankerung der Haltekonstruktion nicht nur in der Schalung, sondern im Ortbeton selbst ermöglicht wird. Ein weiterer wesentlicher Vorteil dieser Ausführungsvariante gegenüber gesonderten Befestigungsöffnungen oder Befestigungsmitteln im Betonfertigteil liegt darin, dass der Ort der Anbringung der Haltekonstruktion auf der Baustelle völlig frei wählbar ist, indem die Anker entsprechend ausgerichtet werden.A particularly favored embodiment of the method according to the invention provides that at least one anchor for the attachment of a support structure is inserted before the introduction of the concrete, which is supported in the water drainage channel and is partially poured into the concrete. A particular advantage of this embodiment is that a secure anchoring of the support structure is made possible not only in the formwork, but in the in-situ concrete itself. Another significant advantage of this embodiment over separate mounting holes or fasteners in precast concrete is that the place of attachment of the support structure on the site is completely free selectable by the anchor are aligned accordingly.

Weiters betrifft die vorliegende Erfindung einen Betonfertigteil zur Herstellung eines Balkons oder einer Terrasse in situ, mit einer vorderen Sichtfläche, die dazu vorgesehen ist, eine Stirnfläche des Balkons oder der Terrasse zu bilden, einer oberen Begrenzungsfläche, die dazu vorgesehen ist, bündig mit einer Oberfläche des Balkons oder der Terrasse zu sein, einer unteren Begrenzungsfläche, die dazu vorgesehen ist, bündig mit einer unteren Fläche des Balkons oder der Terrasse zu sein, und einer Anschlussfläche, die der vorderen Sichtfläche gegenüberliegt und die dazu vorgesehen ist, formschlüssig dem eingegossenen Beton verbunden zu sein. Erfindungsgemäß ist vorgesehen, dass der Betonfertigteil eine Wasserablaufrinne aufweist, die dazu ausgebildet ist, eine Haltekonstruktion wie beispielsweise ein Geländer zu befestigen. Ein solcher Betonfertigteil ist in besonders begünstigter Weise zur Durchführung der oben beschriebenen Verfahren geeignet.Furthermore, the present invention relates to a precast concrete element for producing a balcony or terrace in situ, with a front visible surface intended to form an end face of the balcony or terrace, an upper boundary surface intended to be flush with a surface the balcony or the terrace, a lower boundary surface, which is intended to be flush with a lower surface of the balcony or the terrace, and a connection surface, which is opposite to the front visible surface and which is provided, positively connected to the cast concrete to be. According to the invention it is provided that the precast concrete part has a water drainage channel, which is adapted to secure a support structure such as a railing. Such a precast concrete part is particularly suitable for carrying out the method described above.

Eine konstruktiv besonders begünstigte Lösung sieht vor, dass er aus einem im Querschnitt im Wesentlichen rechteckigen Hauptkörper besteht, in dem die Wasserablaufrinne aufgenommen ist, sowie aus einer vom Hauptkörper vorstehenden Längsrippe, die eine vordere Sichtfläche des Balkons bildet. Ein Vorteil dieser Lösung ist, dass durch die sich ergebende Abstufung des Profils ein besonders guter Halt im Ortbeton erreicht wird. Darüber hinaus ist es möglich, die Betonfertigteile mit geringem Gewicht auszubilden, so dass die Manipulation auf der Baustelle erleichtert wird.A structurally particularly favored solution provides that it consists of a substantially rectangular in cross section main body in which the water gutter is received, as well as from the main body projecting longitudinal rib, which forms a front visible surface of the balcony. An advantage of this solution is that the resulting gradation of the profile a particularly good hold in site concrete is achieved. In addition, it is possible to form the precast concrete parts with low weight, so that the manipulation on the construction site is facilitated.

Der erfindungsgemäße Betonfertigteil kann eine Wasserablaufrinne aufweisen, die nach oben hin offen ausgebildet ist, so dass das vom Balkon ablaufende Wasser in optimaler Weise aufgenommen werden kann. In Bereichen, in denen eine offenen Wasserablaufrinne aus optischen oder funktionellen Gründen störend ist, kann jedoch auch ein geschlossenes System mit mindestens einem Gully vorgesehen sein.The precast concrete part according to the invention may have a water drainage channel, which is designed to be open at the top, so that the water draining from the balcony can be received in an optimum manner. In areas where an open water gutter is disturbing for optical or functional reasons, however, a closed system with at least one drain can also be provided.

Eine weitere Verbesserung der Verbindung mit dem Ortbeton kann dadurch erfolgen, dass aufgeraute Oberflächenabschnitte vorgesehen sind.A further improvement of the connection with the in-situ concrete can be achieved by providing roughened surface sections.

In weiterer Folge betrifft die Erfindung ein Betonfertigteilsystem mit einem Betonfertigteil oben beschriebenen Art. Erfindungsgemäß ist ein solches Betonfertigteilsystem insbesondere durch einen Anker gekennzeichnet, der einen Abstützabschnitt aufweist, der dazu ausgebildet ist, sich in der Wasserablaufrinne abzustützen, sowie einen Eingussabschnitt, der dazu vorgesehen ist, in den Beton eingegossen zu werden. Besonders günstig ist es in diesem Zusammenhang, wenn der Anker einen in Einbaulage waagrechten Abschnitt aufweist, von dem zwei Schenkel vorspringen, deren Neigung den Seitenwänden der Wasserablaufrinne angepasst ist, und die den Abstützabschnitt bilden. Der Anker hat in diesem Fall einerseits die Funktion einer optimalen Abstützung der Haltekonstruktion, zum anderen aber auch die Funktion einer zusätzlichen Verankerung des Betonfertigteils gegenüber dem Ortbeton.In the following, the invention relates to a precast concrete system with a precast concrete part described above. According to the invention, such precast concrete system is characterized in particular by an anchor having a support portion which is adapted to support itself in the water gutter, and a sprue section, which is provided for this purpose to be poured into the concrete. In this connection, it is particularly favorable when the armature has a horizontal section in the installation position, from which project two legs whose inclination is adapted to the side walls of the water drainage channel, and which form the support section. The anchor has in this case, on the one hand, the function of an optimal support of the support structure, on the other hand, but also the function of an additional anchoring of the precast concrete part against the in-situ concrete.

Eine in der Praxis besonders vorteilhafte Gesamtlösung wird erreicht, wenn weiters mindestens ein Stirnschalelement vorgesehen ist, das als weiterer Betonfertigteil ausgebildet ist und das eine Aufnahmefläche zur Abstützung des Betonfertigteils mit der Wasserablaufrinne aufweist.A particularly advantageous in practice overall solution is achieved if further provided at least one end formwork element, which is designed as another precast concrete element and which has a receiving surface for supporting the precast concrete part with the water drainage channel.

Um ein sicheres Ablaufen von Regenwasser zu ermöglichen, wird stets gefordert, dass die Oberfläche eines Balkons oder Terrasse eine geringfügige Neigung aufweist. Die Herstellung dieser Neigung wird insbesondere erleichtert, wenn das Stirnschalelement eine in Einbaulage geneigte Abzugsfläche zur Herstellung einer Ortbetonoberfläche aufweist. Oftmals wird es jedoch als unschön empfunden, wenn die Neigung einer Balkonoberfläche in einer Seitenansicht sichtbar ist. In diesem Zusammenhang ist es daher aus optischen Gründen besonders bevorzugt, wenn die Abzugsfläche nach außen von einer Rippe überdeckt ist, die eine in Einbaulage waagrechte Oberkante aufweist. Ein solcher Balkon besitzt daher in einer seitlichen Ansicht scheinbar eine waagrechte Oberfläche.To ensure a safe drainage of rainwater, it is always required that the surface of a balcony or terrace has a slight incline. The production of this inclination is particularly facilitated if the end formwork element has an inclined in installation position deduction surface for the production of an in-situ concrete surface. Often, however, it is perceived as unattractive when the inclination of a balcony surface is visible in a side view. In this context, it is therefore particularly preferred for optical reasons, when the withdrawal surface is covered to the outside by a rib which has a horizontal upper edge in the installed position. Such a balcony therefore apparently has a horizontal surface in a lateral view.

Letztlich betrifft die vorliegende Erfindung ein Gebäude mit einem Balkon oder einer Terrasse, die einen Betonfertigteil der oben beschriebene Art aufweist oder die unter Verwendung eines Betonfertigteilsystems der oben beschriebenen Art hergestellt ist.Finally, the present invention relates to a building with a balcony or a terrace, which has a precast concrete part of the type described above or fabricated using a precast concrete system of the type described above.

Das Betonfertigteilsystem von Fig. 1 besteht aus einem Betonfertigteil 1, einem Stirnschalelement 2 und einem Anker 3. Es ist klar, dass je nach Art und Abmessungen des herzustellenden Balkons mehrere Betonfertigteile 1 in Axialrichtung nacheinander vorgesehen sein können, dass an der gegenüberliegenden Seite ein spiegelbildliches Stirnschalelement 2 vorgesehen sein kann, und dass je nach Bedarf, d.h. je nach Anzahl der Stützen der anzubringenden Haltekonstruktion, beliebig viele Anker 3 eingelegt sind, die dazu ausgebildet sind, eine Haltekonstruktion 4 beispielsweise für ein Geländer oder einen Wintergarten aufzunehmen.It is clear that, depending on the type and dimensions of the balcony to be produced, several precast concrete elements 1 can be provided successively in the axial direction, that on the opposite side a mirror-image Front scarf element 2 may be provided, and that as needed, ie depending on the number of supports of the support structure to be mounted, any number of anchors 3 are inserted, which are adapted to receive a support structure 4, for example, for a railing or conservatory.

Ein Betonfertigteil 1 besteht aus einem Hauptkörper 5, von dem nach unten eine Längsrippe 6 vorsteht, deren Vorderseite gemeinsam mit der Vorderseite des Hauptkörpers die Sichtfläche 7 des herzustellenden Balkons bildet. Im Hauptkörper 5 ist ein sich in Längsrichtung erstreckende Wasserablaufrinne 8 ausgebildet, die geneigte Flanken 9, 10 aufweist. An der Unterseite der Längsrippe 6 ist eine Nut 11 zur Ausbildung einer Tropfnase vorgesehen. Gegebenenfalls kann bereits bei der Herstellung eine nicht dargestellte Abflussöffnung nach unten vorgesehen sein oder auch auf der Baustelle hergestellt werden, um ein Fallrohr anzuschließen.A prefabricated concrete part 1 consists of a main body 5, projecting from the bottom of a longitudinal rib 6, the front side together with the front of the main body forms the visible surface 7 of the balcony to be manufactured. In the main body 5 is a longitudinally extending water drainage channel 8 is formed, the inclined flanks 9, 10 has. At the bottom of the longitudinal rib 6, a groove 11 is provided for forming a drip nose. Optionally, a drain opening, not shown, may already be provided at the bottom or may be produced at the construction site in order to connect a downpipe.

Der Betonfertigteil 1 wird bei der Herstellung des Balkons auf einer in Fig. 2 nur angedeuteten unteren Schalplatte 12 aufgelegt und bildet somit eine erste Stirnschalung. In besonders bevorzugter Weise werden zuvor seitliche Stirnschalelemente 2 aufgelegt, die an ihrem vorderen Ende eine waagrechte Aufnahmefläche 14 und eine senkrechte Aufnahmefläche 15 aufweisen, auf denen der Betonfertigteil 1 aufliegt. Danach werden die Anker 3 an den erforderlichen Stellen eingelegt, und es wird Ortbeton 3 in die so hergestellte Schalung eingebracht.The prefabricated concrete part 1 is placed in a production of the balcony on a in Fig. 2 only indicated lower formwork panel 12 and thus forms a first end formwork. In a particularly preferred manner previously lateral end formwork elements 2 are placed, which have at their front end a horizontal receiving surface 14 and a vertical receiving surface 15, on which the precast concrete part 1 rests. Thereafter, the anchors 3 are inserted in the required places, and it is in-situ concrete 3 is introduced into the formwork so produced.

In Fig. 3 ist ein Stirnschalelement 2 detailliert dargestellt. Das Stirnschalelement 2 besitzt eine im Wesentlichen ebene Auflagefläche 16, mit der es auf einer unteren Schalplatte 12 aufliegt. Im oberen Abschnitt ist eine leicht geneigte Abzugsfläche 17 vorgesehen, deren Neigung dem geforderten Gefälle des Balkons entspricht. Eine Rippe 18 steht über die geneigte Abzugsfläche 17 nach oben vor und besitzt eine in Einbaulage waagrechte Oberfläche 19. Die Abzugsfläche 17 dient als Lehre zum Abziehen der Oberfläche des Betons 13.In Fig. 3, an end formwork element 2 is shown in detail. The front shell element 2 has a substantially flat support surface 16 with which it rests on a lower shell plate 12. In the upper section, a slightly inclined withdrawal surface 17 is provided, whose inclination corresponds to the required slope of the balcony. A rib 18 protrudes upwards beyond the inclined withdrawal surface 17 and has a horizontal surface 19 in the installed position. The withdrawal surface 17 serves as a jig for removing the surface of the concrete 13.

Fig. 4 zeigt einen Anker 3 im Detail. Der Anker 3 besitzt einen in Einbaulage waagrechten Abschnitt 20, von dem schräg nach unten zwei Schenkel 21, 22 vorspringen, die dazu ausgebildet sind, an den Flanken 9, 10 der Wasserablaufrinne 8 anzuliegen. Der waagrechte Abschnitt 20 bildet zusammen mit den Schenkeln 21, 22 einen Abstützabschnitt 23. An diesen Abstützabschnitt 23 schließt ein senkrechter Schenkel 24 an, der sich in einen waagrechten Endabschnitt 25 fortsetzt, der zusammen mit dem senkrechten Schenkel 24 den Eingussabschnitt 26 bildet. Der senkrechte Schenkel 24 stützt sich außen am Betonfertigteil 1 ab, so dass der Anker 3 nach dem Einlegen in der gewünschten Lage verbleibt.Fig. 4 shows an armature 3 in detail. The armature 3 has a horizontal position in the mounting position 20, projecting obliquely downwards from two legs 21, 22, which are adapted to abut the flanks 9, 10 of the water drainage channel 8. The horizontal portion 20 forms together with the legs 21, 22 a support portion 23. At this support portion 23 includes a vertical leg 24, which continues in a horizontal end portion 25 which forms the sprue portion 26 together with the vertical leg 24. The vertical leg 24 is supported on the outside of the precast concrete part 1, so that the armature 3 remains in the desired position after insertion.

Im Bereich des waagrechten Abschnitts 20 ist ein Befestigungsmittel, wie beispielsweise eine Bohrung 27 oder ein Gewinde oder dgl. vorgesehen, um die Stützkonstruktion 4 befestigen zu können.In the region of the horizontal portion 20, a fastening means, such as a bore 27 or a thread or the like. Provided to secure the support structure 4 can.

Die vorliegende Erfindung ermöglicht es, Balkone und Terrassen in einfacher Weise herzustellen, wobei die an der Baustelle durchzuführenden Arbeiten minimiert werden. Insbesondere ist es möglich, Stützkonstruktionen, wie etwa Geländer, anzubringen, ohne Öffnungen oder Bohrungen anbringen zu müssen, die im Nachhinein aufwendig verschlossen werden müssen und eine häufige Nachbesserungen erforderlich machen.The present invention makes it possible to produce balconies and terraces in a simple manner, while minimizing the work to be carried out on the construction site. In particular, it is possible to support structures, such as railings to install without having to attach openings or holes that need to be closed consuming afterwards and make frequent repairs required.
