Description

Die Erfindung betrifft eine Einrichtung zum Auffangen und Ab­leiten von beim Bearbeiten von Bauwerkoberflächen, Gebäudefas­saden und dergleichen, insbesondere bei Sanierungsarbeiten an­fallenden, mit Schadstoffen belasteten Flüssigkeiten.The invention relates to a device for collecting and draining liquids that are contaminated with pollutants when machining building surfaces, building facades and the like, in particular during renovation work.

Bei der Oberflächenbehandlung von Bauwerken, beispielsweise beim Reinigen, Abbeizen und Konservieren von Gebäudefassaden fallen erhebliche Mengen an Schmutzwasser, Schlamm, Putz, Farbresten und dergleichen an. Aufgrund der verschärften Auf­lagen für den Umweltschutz sind diese Rückstände lückenlos aufzufangen, zu sammeln und sachgerecht zu entsorgen. Da Ar­beitserfolge vielfach nur mit Hilfe von Hochdruckreinigungsge­räten zu erzielen sind, besteht die Gefahr, daß die anfallen­den Reinigungs- und Schmutzwassermengen unkontrolliert im Erd­reich oder in der öffentlichen Kanalisation verschwinden. Die bisher bekannten Maßnahmen zum Auffangen und gezielten Ableiten der gesammelten Abwassermengen erwiesen sich insbesondere bei der Oberflächenbehandlung mittels Hochdruckgeräten als bei weitem nicht ausreichend. Hierzu gehören die am unteren Ende der zu bearbeitenden Oberflächen der Bauwerke aufgestellten Fangrinnen. Diese sind kaum in der Lage, an den Gebäudefas­ saden nach unten ablaufende flüssige Reinigungsmittel aufzu­fangen. Für das Auffangen und Sammeln der von Bauwerksober­flächen abspritzenden flüssigen Reinigungsmittel sind die bis­her bekannten Auffangrinnen gänzlich ungeeignet, denn durch Hochdruck aufgetragene Reinigungsmittel spritzen zu einem erheb­lichen Teil in das Baugerüst zurück und tropfen von dort un­kontrolliert auf das Erdreich. Die übliche, an der Außenseite eines Baugerüstes verwendete Schutzplane kann lediglich dafür sorgen, daß die zurückspritzenden Flüssigkeitsmengen nicht weiter nach außen gelangen, sondern sich überwiegend auf den Grundriß des aufgestellten Gerüstes beschränken. Das lücken­lose Auffangen wird insbesondere auch deshalb erschwert, weil Baugerüste dem Fassadenlauf folgen und zwangsläufig Ecken auf­weisen, welche die Sammeleinrichtungen unterbrechen. Eine Ein­richtung, die den behördlichen Auflagen für den Umweltschutz entsprechen und die zum Bearbeiten der Bauwerksflächen verwen­deten Flüssigkeiten wieder lückenlos auffangen, ist nicht be­kannt.In the surface treatment of buildings, for example when cleaning, stripping and preserving building facades, considerable amounts of dirty water, mud, plaster, paint residues and the like are produced. Due to the stricter environmental protection requirements, these residues must be collected, collected and disposed of properly. Since successful work can often only be achieved with the help of high-pressure cleaning devices, there is a risk that the amounts of cleaning water and wastewater generated will disappear in an uncontrolled manner in the ground or in the public sewer system. The previously known measures for collecting and deliberately discharging the collected wastewater quantities have proven to be far from sufficient, particularly in the case of surface treatment using high-pressure devices. This includes the gutters set up at the lower end of the surfaces of the structures to be processed. These are hardly able to work on the building facades saden to drain down liquid detergents. The previously known collecting channels are completely unsuitable for collecting and collecting the liquid cleaning agents spraying from building surfaces, because cleaning agents applied by high pressure spray to a considerable extent back into the scaffolding and drip uncontrollably from there onto the ground. The usual protective tarpaulin used on the outside of a scaffolding can only ensure that the splashing back liquid quantities do not reach the outside, but are mainly limited to the floor plan of the erected scaffolding. The seamless collection is particularly difficult because scaffolding follows the facade and inevitably have corners that interrupt the collection facilities. A facility that meets the official requirements for environmental protection and that gathers the fluids used to process the building surfaces is not known.

Der Erfindung liegt die Aufgabe zu Grunde, eine Auffangein­richtung der einleitend genannten Gattung zu schaffen, mit der es möglich ist, die gesamte zur Reinigung, zum Abbeizen, zum Konservieren und dergleichen verwendeten Flüssigkeit am unteren Ende der zu bearbeitenden Fläche aufzufangen und zwar auch dann, wenn sie mit Hilfe von Hochdruckgeräten gegen die zu bearbeitende Fläche gestrahlt wird. Die Einrichtung soll in der Lage sein, ohne Unterbrechung dem Verlauf des Baugerüstes zu folgen, auch wenn dieses an Gebäudeecken angeordnet ist und scharfen Rich­tungsänderungen der Bauwerksfronten folgt. Die Erfindung zur Lösung dieser Aufgabe ist durch handelsübliche Dachrinnenab­schnitte gekennzeichnet, die durch separate Verbindungsteile zusammenfügbar sind, welche im Bereich der Pfosten eines Bauge­rüstes mit Einbuchtungen zum Umfassen der Pfosten versehen sind, wobei die Rinnenabschnitte in an den Pfosten befestig­baren Haltern ruhen und die Abstände zwischen an den beiden Längsseiten des Gerüstes angeordneten Rinnen einerseits und zwischen der zu bearbeitenden Bauwerkfläche und der dieser be­nachbarten Rinne anderseits mit Folien überbrückbar sind.The invention is based on the object of providing a collecting device of the type mentioned in the introduction, with which it is possible to collect all of the liquid used for cleaning, stripping, preserving and the like at the lower end of the surface to be processed, even then, if it is blasted against the surface to be worked with the help of high-pressure devices. The facility should be able to follow the course of the scaffolding without interruption, even if it is arranged on building corners and follows sharp changes in direction of the building fronts. The invention for solving this problem is characterized by commercially available gutter sections which can be joined together by separate connecting parts which are provided in the area of the posts of a scaffolding with indentations for encompassing the posts, the gutter sections resting in holders which can be fastened to the posts and the distances between the two Channels arranged on the long sides of the scaffold can be bridged with foils on the one hand and between the building surface to be machined and the adjacent gutter on the other.

Weitere, den Erfindungsgegenstand vorteilhaft gestaltende Merk­male sind in den Unteransprüchen angegeben.Further features which advantageously shape the subject matter of the invention are specified in the subclaims.

Der gesamte Bereich zwischen der zu bearbeitenden Bauwerkfläche und der dem Bauwerk abgekehrten Seite des Baugerüsts kann dicht oberhalb des Erdreichs durch die Folien abgedeckt werden, wobei die sich darauf sammelnde Flüssigkeit in die Rinnen geleitet und von diesen gezielt in Lagerbehälter abgeführt wird. Selbst die von der zu bearbeitenden Fläche zurückspritzende Flüssig­keitsmenge kann mit Sicherheit aufgefangen werden, da die üb­licherweise an den Außenseiten der Baugerüste verwendete Plane im Bereich oberhalb der äußeren Rinnen endet und dadurch die an der Plane nach unten laufende Flüssigkeit darin gefangen und abgeführt werden kann.The entire area between the surface of the building to be processed and the side of the scaffolding facing away from the building can be covered by the foils just above the soil, the liquid collecting thereon being directed into the channels and being discharged from there into storage containers. Even the amount of liquid splashing back from the surface to be worked can be collected with certainty, since the tarpaulin usually used on the outside of the scaffolding ends in the area above the outer channels, and the liquid that runs down the tarpaulin can thereby be caught and removed.

Durch die Einbuchtungen der Verbindungsteile werden die Pfosten dichtend umfaßt. Die nicht flüssigkeitsdichte Spalte zwischen den Verbindungsteilen und dem Pfosten können durch elastische Dichtungsmasse oder durch eine am Verbindungsteil angebrachte Abdeckkappe abgedichtet werden. Die flexiblen Verbindungsteile sind in der Lage, auch rechtwinkligen Rich­tungsänderungen des Baugerüstes zu folgen. Die Befestigung ist an allen bekannten Gerüstsystemen möglich.Through the indentations of the connecting parts, the posts are sealed. The non-liquid-tight gaps between the connecting parts and the post can be sealed by means of elastic sealing compound or by a cover cap attached to the connecting part. The flexible connecting parts are able to follow right-angled changes in direction of the scaffolding. Attachment is possible on all known scaffolding systems.

Sofern bei Sanierungsarbeiten Feststoffe anfallen und dadurch die Gefahr besteht, die in diesem Bereich zwischen der zu be­arbeitenden Gebäudefläche und der innenseitigen Rinne aufge­spannte Folie zu beschädigen, sorgt ein oberhalb der Rinnen befestigbares Prallblech für das Auffangen der Feststoffe, bei­spielsweise Putzteile und Ziegelsplitter. Dabei kann Flüssig­keit durch siebartige Öffnungen in dem Prallblech nach unten abtropfen.If solids accumulate during renovation work and there is a risk of damaging the film stretched in this area between the building surface to be treated and the inside gutter, a baffle plate that can be attached above the gutters ensures that the solids are caught, for example cleaning parts and brick fragments. Liquid can drip down through sieve-like openings in the baffle plate.

Mit der erfindungsgemäßen Einrichtung ist es möglich, alle vor­kommenden variablen Abstände zwischen dem Baugerüst und dem Bau­werk auszugleichen. Es besteht aus wenigen vorgefertigten, hand­lichen Teilen, die problemlos montierbar sind. Das Herstellen von Bohrungen zum Anschrauben von Anschlußleisten an Bauwerken, was insbesondere bei historischen Bauwerken nicht zulässig ist, entfällt. Die durch Kraftschluß an den Pfosten befestigbaren Halter können an beliebiger Stelle und in jeder Höhe angeord­net werden.With the device according to the invention, it is possible to compensate for all occurring variable distances between the scaffolding and the building. It consists of a few prefabricated, handy parts that can be easily assembled. There is no need to drill holes for screwing connection strips onto structures, which is not permissible, particularly in historical structures. The brackets, which can be attached to the post by friction, can be arranged at any point and at any height.

Das Verbin­dungsteil 3 nach Fig. 2 zeigt zwei nebeneinander angeordnete Einbuchtungen für zwei nebeneinander angeordnete Gerüstpfosten, beispielsweise an Gerüstverbindungsstellen. Eine kurze Aus­führung 6 mit einer Einbuchtung ist in Fig. 3 dargestellt. Im Bereich zwischen den Pfosten sind Verbindungsteile 7, 8 und 35 (Fig. 11) ohne Einbuchtungen verwendbar. An den Enden der Verbindungsteile sind absatzartige Nuten 9 zur Aufnahme von Dichtstreifen 10 für die Herstellung flüssigkeitsdichter Ver­bindungen mit den sich daran anschließenden, nicht näher dar­gestellten, handelsüblichen Dachrinnenabschnitten 34 (Fig. 15,16).The connecting part 1 according to FIG. 1 is provided with an indentation 2 for enclosing a scaffold post 32. The connecting part 3 according to FIG. 2 shows two indentations arranged next to one another for two scaffold posts arranged next to one another, for example at scaffold connection points. A short version 6 with an indentation is shown in FIG. 3. In the area between the posts, connecting parts 7, 8 and 35 (FIG. 11) can be used without indentations. At the ends of the connecting parts are shoulder-like grooves 9 for receiving sealing strips 10 for the production of liquid-tight connections with the adjoining, not shown, commercially available gutter sections 34 (FIGS. 15, 16).

Die Rinnenhalter 11, 12 und 13 bestehen aus halbkreisförmigen Klemmringteilen 14 und 15, die mit Hilfe von Drehzapfen 16 scharnierartig verbunden und mittels Schrauben 17 nach Umfas­sen eines Gerüstpfostens fest gegeneinander preßbar sind. An einem der Klemmringteile sind Haltearme 18 angeschweißt, die ihrerseits angeschweißte flache Halteprofile 19 tragen, auf welchen die bügelförmigen Halter 20 zur Aufnahme der Rinnenab­schnitte befestigt, beispielsweise angeschweißt sind. Das Beispiel gemäß Fig. 6 unterscheidet sich von dem nach der Fig. 7 lediglich durch die Anordnung des Haltebügels auf der gegenüberliegende Seite des Klemmrings. Das Ausführungsbei­spiel gemäß Fig. 8 zeigt zwei bügelförmige Halter zu beiden Seiten des Klemmrings 14, 15.The gutter brackets 11, 12 and 13 consist of semicircular clamping ring parts 14 and 15, which are connected in a hinge-like manner with the aid of pivot pins 16 and can be pressed firmly against one another by means of screws 17 after embracing a scaffold post. Holding arms 18 are welded to one of the clamping ring parts, which in turn carry welded flat holding profiles 19, on which the bow-shaped holders 20 for receiving the channel sections are fastened, for example welded. The example according to FIG. 6 differs from that according to FIG. 7 only by the arrangement of the holding bracket on the opposite side of the clamping ring. The exemplary embodiment according to FIG. 8 shows two bow-shaped holders on both sides of the clamping ring 14, 15.

Um dem Verlauf von Gebäudefassaden mit Ecken und Vorsprüngen folgen zu können, zeigt das Verbindungsteil 21 gemäß Fig. 9 einen starren Verbindungsanschluß 22 und einen flexiblen Ver­ bindungsanschluß 23. Dieser besteht aus mehreren, mit Abstand zueinander angeordneten Rippen 24, zwischen denen sich flexible Wandteile 25 erstrecken.In order to be able to follow the course of building facades with corners and projections, the connecting part 21 according to FIG. 9 shows a rigid connecting connection 22 and a flexible Ver binding connection 23. This consists of several spaced-apart ribs 24, between which flexible wall parts 25 extend.

Das Verbindungsteil 26 gemäß Fig. 10 zeigt eine Doppeleinbuch­tung mit beidseitig angeordneten, flexiblen Anschlußteilen. Flexible Verbindungsteile ohne Einbuchtungen können gemäß Fig. 11 ausgeführt sein.The connecting part 26 according to FIG. 10 shows a double indentation with flexible connecting parts arranged on both sides. Flexible connecting parts without indentations can be designed according to FIG. 11.

Der aus Rinnen, Verbindungsteilen und Folien bestehenden Ein­richtung kann ein Prallblech 27 (Fig. 12) hinzugefügt werden, das an dem Baugerüst oberhalb der Folien befestigbar ist. Das Prallblech ist an seinen Schmalseiten mit nach unten abgekan­teten Blechstreifen 28 versehen, mit welchen es in U-förmige Halteprofile 29 eingehängt werden kann. Die U-Profile 29 wer­den durch Haltebügel 30 getragen, die ihrerseits jeweils mit einem zweiteiligen, verschraubbaren Klemmring 31 fest verbun­den sind. Das Prallblech 27 kann siebartig ausgeführt werden, um an den Feststoffpartikeln haftendes Schmutzwasser und der­gleichen abtropfen zu lassen.A baffle 27 (FIG. 12) can be added to the device consisting of channels, connecting parts and foils, which can be fastened to the scaffolding above the foils. The baffle plate is provided on its narrow sides with sheet strips 28 which are bent downwards and with which it can be hung in U-shaped holding profiles 29. The U-profiles 29 are carried by holding brackets 30, which in turn are each firmly connected to a two-part, screwable clamping ring 31. The baffle plate 27 can be designed in the form of a sieve in order to drain dirty water and the like adhering to the solid particles.

Das Ausführungsbeispiel gemäß Fig. 15 zeigt ein Baugerüst mit senkrechten Pfosten 32, das an einer zu reinigenden Ge­bäudewand mit einem Eckvorsprung 33 aufgestellt ist. Das Gerüst folgt diesem Vorsprung. Dementsprechend muß die gesamte Auf­fangeinrichtung mit allen Einzelteilen diesem Verlauf folgen. Die handelsüblichen Dachrinnenabschnitte 34 sind mit den in den Fig. 1 bis 11 dargestellten Verbindungsteilen an den senk­rechten Gerüstpfosten befestigt. Von den an der Innenseite des Gerüstes befestigten Rinnenabschnitten erstreckt sich eine Fo­lie 40 mit aufwärts gerichteter Neigung bis an die Gebäudewand und ist dort mit Hilfe eines Selbstklebestreifens 41 befestigt. Der Bereich zwischen den Rinnen, also innerhalb des Baugerüstes, ist mit einer weiteren Folie 42 überdeckt. Sie ist ebenfalls mit Klebestreifen an den Rinnenkanten befestigt. Um eine aus­reichende Neigung für die aufzufangende Flüssigkeit zu erhal ten, ist die gesamte an den Außenpfosten des Gerüstes be­festigte Rinne oberhalb der innenseitigen Rinne angeordnet. Die aufgefangene Flüssigkeit kann in einen Zwischenbehälter 50 geleitet werden, von wo sie über eine Tauchpumpe 51 in einen fahrbaren Tank 52 leitbar ist. Sofern vorhanden, kann bereits am Einsatzort die zu entsorgende Flüssigkeit in einen Neu­tralisierungs- und Reinigungstank 53 geleitet werden, von wo die Flüssigkeit im Recyclingverfahren über einen Kompressor 54 erneut zum Einsatz gelangen kann.15 shows a scaffolding with vertical posts 32, which is set up on a building wall to be cleaned with a corner projection 33. The scaffolding follows this lead. Accordingly, the entire collecting device with all its individual parts must follow this course. The commercial gutter sections 34 are fastened to the vertical scaffold posts with the connecting parts shown in FIGS. 1 to 11. A film 40 with an upward inclination extends from the gutter sections fastened to the inside of the scaffold to the building wall and is fastened there by means of a self-adhesive strip 41. The area between the channels, that is to say within the scaffolding, is covered with a further film 42. It is also attached to the gutter edges with adhesive strips. To get a sufficient inclination for the liquid to be collected ten, the entire gutter attached to the outer posts of the scaffold is arranged above the inner gutter. The collected liquid can be passed into an intermediate container 50, from where it can be conducted into a mobile tank 52 via a submersible pump 51. If available, the liquid to be disposed of can be fed into a neutralization and cleaning tank 53 at the place of use, from where the liquid can be used again in the recycling process via a compressor 54.

An der Außenseite des Baugerüstes werden üblicherweise Gerüst­schutzplanen 60 aufgehängt, die ein zu weites Abspritzen der mit Hochdruck verarbeiteten Flüssigkeit verhindern sollen. Diese Planen können bis in die Rinnen 34 reichen, so daß an den Innenseiten ablaufende Flüssigkeit mit Sicherheit aufgefangen und abgeleitet wird. Zu diesem Zweck ist die Außenseite der Rinne nach außen weisend am Gerüst befestigt.Scaffolding tarpaulins 60 are usually hung on the outside of the scaffolding and are intended to prevent the liquid processed under high pressure from spraying too far. These tarpaulins can extend into the grooves 34, so that liquid running off on the inside is collected and drained with certainty. For this purpose, the outside of the channel is attached to the scaffold pointing outwards.
