Beschreibung description
Der Bau von Eiformfaulbehältern, wie sie bei Kläranlagen gebaut werden, wird dadurch sehr erschwert, dass es keine zum Bau solcher Bauten geeigneten Arbeitsgerüste gibt. Mit behelfsmässigen Arbeitsgerüsten geht die Arbeit sehr langsam und ist dadurch auch sehr kostenaufwendig. The construction of egg-shaped digesters, such as those built in sewage treatment plants, is made very difficult by the fact that there are no working scaffolds suitable for the construction of such structures. With makeshift scaffolding, the work goes very slowly and is therefore also very expensive.
Die Erfindung stellt sich nun die Aufgabe, Arbeitsgerüste zu entwickeln, womit der Bau von Eiformfaulbehältern rasch und kostengünstig ausgeführt werden kann. The object of the invention is now to develop scaffolding with which the construction of egg digesters can be carried out quickly and inexpensively.
Dies wird mit Arbeitsgerüsten erreicht, welche die Merkmale des Patentanspruches 1 aufweisen. This is achieved with work scaffolds that have the features of claim 1.
Im folgenden werden nun einige Ausführungsbeispiele der Erfindung anhand der beiliegenden Zeichnungen eingehend beschrieben. Some exemplary embodiments of the invention will now be described in detail below with reference to the accompanying drawings.
Fig. 1 zeigt einen Eiformfaulbehälter im Schnitt, wobei ein Betonierabschnitt bis zum Äquator des Eiformfaulbehälters eingeschalt ist und Fig. 2 zeigt einen weiteren Betonierabschnitt über dem Äquator des Eiformfaulbehälters eingeschalt. 1 shows a section of an egg-shaped digester, wherein a concreting section up to the equator of the egg-shaped digester is formed, and FIG. 2 shows another concreting section above the equator of the egg-shaped digester.
Fig. 1 zeigt den unteren Teil eines Eiformfaulbehälters im Bau im Schnitt. Links in Fig. 1 ist der Trichter und der erste Betonierabschnitt mit zweifach gekrümmter Wand ausgeschalt. Der zweite Betonierabschnitt der zweifach gekrümmten Wand ist eingeschalt. An der Innenschalung sind drei Druckringe 3 angeordnet. Die Schalung ist nicht durchgebunden, wodurch beim Betonieren ein wesentlicher Ringdruck entsteht. Aus diesem Grunde ist in diesem Beispiel ein Breitflanschprofil für die Druckringe 3 und die Zugringe 4 vorgesehen. Die Breitflanschprofile 3 sind derart gerundet, dass die Flanschen der Profile vertikal angeordnet sind. Damit bildet der innere Flansch des Druckringes 3 eine ideale Laufschiene für in Umfangrichtung verfahrbare Arbeitsgerüste. In Fig. 1 auf der linken Seite ist ein Hänge-Arbeitsgerüst 6 dargestellt. Es ist mittels mehrerer seilrollenartiger Laufrollen 9, welche in Umfangrichtung im Abstand zueinander angeordnet sind, auf dem inneren Flansch des untersten Druckringes 3 in Umfangrichtung verfahrbar geführt. Mittels der Sicherung 13 sind die Laufrollen 9 in der Führung gesichert. Am unteren Ende des Hänge-Arbeitsgerüstes 6 sind im Abstand zueinander Bockrollen 10 angeordnet, welche auf dem ausgeschalten Beton abrollen. Am Hänge-Arbeitsgerüst Fig. 1 shows the lower part of an egg-shaped digester under construction in section. The funnel and the first concreting section with a double-curved wall are removed on the left in FIG. 1. The second concreting section of the double-curved wall is shuttered. Three pressure rings 3 are arranged on the inner formwork. The formwork is not tied through, which creates a significant ring pressure when concreting. For this reason, a wide flange profile for the pressure rings 3 and the pull rings 4 is provided in this example. The wide flange profiles 3 are rounded such that the flanges of the profiles are arranged vertically. The inner flange of the pressure ring 3 thus forms an ideal running rail for work scaffolds which can be moved in the circumferential direction. In Fig. 1 on the left side a suspended scaffolding 6 is shown. It is guided on the inner flange of the lowest pressure ring 3 so as to be movable in the circumferential direction by means of a plurality of pulley-like rollers 9 which are arranged at a distance from one another in the circumferential direction. The rollers 9 are secured in the guide by means of the fuse 13. Fixed castors 10 are arranged at a distance from one another at the lower end of the suspended work scaffold 6 and roll on the concrete that has been switched off. On the hanging scaffolding
6 sind zwei übereinander angeordnete Gerüstgänge 6 are two scaffold aisles arranged one above the other
7 an Stehern 5 angebracht. 7 attached to stands 5.
Eine andere Ausführung eines erfindungsgemäs-sen Arbeitsgerüstes ist in Fig. 1 zur Montage der Innenschalung des zweiten Betonierabschnittes mit zweifach gekrümmter Wand dargestellt. In der Mitte des zu bauenden Eiformfaulbehälters ist ein Fachwerkturm 1 bis zur Äquatorhöhe montiert. An diesem Turm 1 ist eine vertikal verstellbare Plattform 2 angeordnet. An dieser Plattform aufgelagert und in Umfangrichtung drehbar ist eine Brücke 11 Vorgesehen, welche rechts an deren Ende mittels mehrerer seilrollenartiger Laufrollen 9 auf dem inneren Flansch des zweituntersten Druckringes geführt ist. Diese Laufrollen 9 sind mittels der Sicherung 13 gesichert. Auf der Brücke 11 in der Nähe der Innenschalung rechts in Fig. 1 sind nach aussen geneigte Steher 5 angeordnet, an denen zwei Gerüstgänge 7 übereinander montiert sind. Die Steher 5 mit den übereinander angeordneten Gerüstgängen Another embodiment of a work scaffold according to the invention is shown in FIG. 1 for assembling the inner formwork of the second concreting section with a double-curved wall. A half-timbered tower 1 is mounted in the middle of the egg digester to be built up to the equator height. A vertically adjustable platform 2 is arranged on this tower 1. Mounted on this platform and rotatable in the circumferential direction, a bridge 11 is provided, which is guided on the right at its end by means of a plurality of rope pulley-like rollers 9 on the inner flange of the second lowest pressure ring. These rollers 9 are secured by means of the fuse 13. On the bridge 11 near the inner formwork on the right in FIG. 1, upright 5 is arranged, on which two scaffold aisles 7 are mounted one above the other. The uprights 5 with the scaffold aisles arranged one above the other
7 sind in der Neigung verstellbar und bilden eine andere Ausführung eines erfindungsgemässen Arbeitsgerüstes 12. 7 are adjustable in inclination and form another embodiment of a work scaffold 12 according to the invention.
Ganz rechts in Fig. 1 ist zur Montage der Aus-senschalung für den zweiten Betonierabschnitt der zweifach gekrümmten Wand eine andere Ausführung eines in Umfangrichtung verfahrbaren Arbeitsgerüstes dargestellt. Das Arbeitsgerüst 14 ist mittels mehrerer in Abstand zueinander angeordneter Laufrollen 9 am äusseren Flansch eines Zugringes 4 geführt. Damit das Arbeitsgerüst 14 sicher geführt ist, sind am unteren Rand des Flansches des Zugringes 4 im Abstand zueinander Gegenrollen 15 angeordnet. Nachdem der Zugring 4 beim Betonieren sehr straff gespannt wird, ist auch eine solche Lösung möglich. Das Hänge-Arbeitsgerüst 6, die Arbeitsgerüste 12 und 14, die zentrale Plattform 2 und die Brücke 11 sind mittels Schutzgeländer absturzgesichert, wobei aber nur die Geländerstützen On the far right in FIG. 1, another version of a work scaffold that can be moved in the circumferential direction is shown for installing the external formwork for the second concreting section of the double-curved wall. The work scaffold 14 is guided on the outer flange of a pull ring 4 by means of a plurality of rollers 9 arranged at a distance from one another. So that the scaffolding 14 is safely guided, counter rollers 15 are arranged at a distance from one another on the lower edge of the flange of the pull ring 4. After the tension ring 4 is stretched very tight during concreting, such a solution is also possible. The suspended work scaffold 6, the work scaffolds 12 and 14, the central platform 2 and the bridge 11 are secured against falling by means of protective railings, but only the railing supports
8 eingezeichnet sind. 8 are shown.
Fig. 2 zeigt denselben Eiformfaulbehälter im Schnitt. Der erste Betonierabschnitt über dem Äquator ist betoniert und der nächste Betonierabschnitt ist eingeschalt. Links in Fig. 2 ist ein Hänge-Arbeitsgerüst 6 zum Ausschalen der inneren Schalung dargestellt, wobei die innere Schalung schon entfernt ist. Ein solches Hänge-Arbeitsgerüst 6 kann auch zum Ausschalen der Aussenschalung eingesetzt werden. Der Fachwerkturm 1 in der Mitte des zu bauenden Eiformfaulbehälters ist aufgesetzt und die zentrale Plattform 2 ist auf die entsprechende Höhe hochgezogen und festgehalten. Die Brücke 11 ist auf einem Druckring 3 in Umfangrichtung verfahrbar geführt. Die Stützen 5 mit den übereinander angeordneten Gerüstgängen 7 sind nach innen geneigt und damit der zu bauenden zweifach gekrümmten Wand angepasst. Fig. 2 shows the same egg digester in section. The first concreting section above the equator is concreted and the next concreting section is shuttered. On the left in FIG. 2, a suspended work scaffold 6 for stripping the inner formwork is shown, the inner formwork having already been removed. Such a suspended work scaffold 6 can also be used for stripping the outer formwork. The lattice tower 1 is placed in the middle of the egg digester to be built and the central platform 2 is raised and held to the appropriate height. The bridge 11 is guided on a pressure ring 3 so as to be movable in the circumferential direction. The supports 5 with the scaffold aisles 7 arranged one above the other are inclined inwards and are thus adapted to the double-curved wall to be built.
Ganz rechts in Fig. 2 ist eine andere Ausführung eines Arbeitsgerüstes dargestellt. Das Arbeitsgerüst 14 ist an zwei übereinander angeordneten Zugringen 4 mittels Laufrollen 9 in Umfangrichtung verfahrbar geführt. Another embodiment of a work scaffold is shown on the far right in FIG. 2. The scaffolding 14 is guided on two pull rings 4 arranged one above the other by means of rollers 9 so as to be movable in the peripheral direction.
Es gibt viele Möglichkeiten, äussere und innere in Umfangrichtung verfahrbare Arbeitsgerüste zu entwickeln, Voraussetzung dafür ist, dass übereinander an der Aussenschalung und an der Innenschalung ringförmige Laufschienen angeordnet sind. Nachdem die Schalung nicht durchgeankert ist, sind Profile für die Aufnahme des Ringdruckes innen und des Ringzuges aussen notwendig. Diese Profile werden erfindungsgemäss durch Druckringe 3 und Zugringe 4 ersetzt, wodurch die für die Arbeitsgerüste 6, 12 und 14 notwendigen ringförmigen Laufschienen vorhanden sind. There are many options for developing outer and inner work scaffolds that can be moved in the circumferential direction, provided that ring-shaped running rails are arranged one above the other on the outer formwork and on the inner formwork. After the formwork has not been anchored, profiles are required to absorb the ring pressure on the inside and the ring pull on the outside. According to the invention, these profiles are replaced by pressure rings 3 and pull rings 4, as a result of which the annular running rails necessary for the work stands 6, 12 and 14 are present.
