Description
Schalung für langgestreckte Hohlkörper oder Kanäle Die Erfindung betrifft eine durch Luftdruckkörper formbare Schalung für langgestreckte Hohlkörper oder Kanäle aus Beton oder einem ähnlichen Baustoff.Formwork for elongated hollow bodies or channels The invention relates a formwork for elongated hollow bodies that can be shaped by air pressure bodies or Channels made of concrete or a similar building material.
Das Neue besteht darin, daß ein mit der Außenluft verbundener straffbarer Schalungsmantel durch ein oder mehrere innere Luftdruckschläuche zu ebenen Schalungsflächen formbar ist.The novelty consists in the fact that one connected with the outside air can be tightened Formwork jacket through one or more inner air pressure hoses to level formwork surfaces is malleable.
Am Umfang des oder der inneren Luftdruckschläuche können erfindungsgemäß feste Formkörper verwendet werden, welche dann die Kanten der ebenen Flächen abzeichnen.According to the invention, on the circumference of the inner air pressure hose or hoses solid moldings are used, which then mark the edges of the flat surfaces.
Als Verbindungsstücke für zusammenstoßende' Schalungsmäntel und als Träger der Formkörper für Aussparungen in den Wänden des Hohlkörpers oder Kanals können straffbare Manschetten Tiber den oder die Schalungsmäntel gezogen werden.As connecting pieces for colliding 'formwork jackets and as Carrier of the molded body for recesses in the walls of the hollow body or channel Taut sleeves can be pulled over the formwork jacket (s).
Die Erfindung ist in der Zeichnung beispielsweise veranschaulicht.The invention is illustrated in the drawing, for example.
Die Abb. i und 2 stellen schaubildlich und die Abb. 3 und q. in Schnitten verschiedene Schalungen nach der Ertindung dar.Figs. I and 2 represent diagrammatically and Figs. 3 and q. in cuts different formwork after the invention.
a ist ein straffbarer Schalungsmantel, welcher mit der Außenluft verbunden ist; c, cl, c2, c;, c4 sind aufblasbare Luftdruckschläuche und b, 1l, h2, b feste Formkörper, welche am Umfange des oder der inneren Luftdruckschläuche in den Schalungsmantel eingelegt werden. Mit e sind Manschetten bezeichnet, welche die Formkörper f für die Aussparungen fl.in den Wänden g des fertigen Kanals tragen. Die Manschette q dient als Verbindungsstück des Schalungsinantels a finit dem Schalungsmantel z-. Die Abb. 3 zeigt beispielsweise den Querschnitt eines Schalungsmantels a, der unter Verwendung eines Luftdruckschlauches c und eines starren Formkörpers b eine teils ebene, teils runde Schalungsfläche aufweist.a is a stretchable formwork jacket that is connected to the outside air; c, cl, c2, c ;, c4 are inflatable air pressure hoses and b, 1l, h2, b are solid molded bodies which are inserted into the casing around the circumference of the inner air pressure hose or hoses. Cuffs are designated by e, which carry the molded bodies f for the recesses fl in the walls g of the finished channel. The cuff q serves as a connecting piece of the formwork jacket a finitely the formwork jacket z-. Fig. 3 shows, for example, the cross-section of a formwork jacket a, which has a partly flat, partly round formwork surface using an air pressure hose c and a rigid molded body b.
Abb. q. zeigt beispielsweise den Querschnitt eines Schalungsinantels, welcher unter Verwendung von vier Luftdruckschlä nclien cl, c-, c :, c4 ohne Verwendung starrer Formstücke einen rechteckigen Querschnitt mit abgerundeten Ecken aufweist.Fig.q. shows, for example, the cross-section of a casing shell, which using four air pressure hoses cl, c-, c:, c4 without use rigid fittings has a rectangular cross-section with rounded corners.
