A formwork (1) for round structures of concrete has at least one internal formwork cladding (2), which is supported on longitudinal girders (5) spaced apart from one another. The girders (5) again are supported on an endless chain (6), which consists of a number of rails (7), which are adjustable in length but otherwise rigid, which can be angled to one another and fixed in an angled position. Each rail (7) in the endless chain (6) has the advantage of being able to be connected to the following rail (7) through a connector (8) on the girders (5) and can with the help of a joint angle block (9) be fixed in an angled position in relation to the connector (8). Such a formwork endless chain can easily be adapted to various formwork diameters and is furthermore of a very rigid construction, where the individual components are in a form-shaping engagement with one another.<IMAGE>
