A method for assembling a hollow rail (3) for guiding a lift car and/or a counterweight of a lift installation (1) comprises: arranging a first hollow-rail part (4) and a second hollow-rail part (5) at different heights in a lift shaft (2); aligning the first hollow-rail part relative to the second hollow-rail part with the aid of an alignment piece (8), so that the first and the second hollow-rail parts extend along a common longitudinal axis (12), wherein the alignment piece is arranged between the first and the second hollow-rail parts such that the alignment piece projects partly into an open end (6) of the first hollow-rail part and partly into an open end (7) of the second hollow-rail part; fastening a respective bracing element (17a, 17b) on the first and on the second hollow-rail parts; and applying a force to the bracing elements in mutually opposite directions parallel to the common longitudinal axis in order to bring the first and the second hollow-rail parts together to form the hollow rail, wherein the alignment piece is pressed into the open end of the first hollow-rail part and/or of the second hollow-rail part.
