Abstract
A method for assembling a hollow rail for guiding an elevator car and/or a counterweight of an elevator installation includes: arranging a first and second hollow rail parts at different heights in an elevator shaft; aligning the first rail part relative to the second rail part by an alignment piece so that the first and second rail parts extend along a common longitudinal axis, wherein the alignment piece protrudes partially into an open end of the first rail part and partially into an open end of the second rail part; fastening one clamping element to each of the first and second rail parts; and applying a force to the clamping elements in opposite directions parallel to the common longitudinal axis to bring together the first and second rail parts, wherein the alignment piece is pressed into the open end of the first and/or the second rail part.
