Abstract A method and a system of erecting tower buildings from segments of optional cross-sectional shapes to be mounted on top of each other. The object of the method is to facilitate the erection of tall buildings, such as pulp digesters, silos, chimneys and the like, in which mobile cranes cannot be utilized. This object is realized in that each segment is provided with at least one beam or profile member which serves as a guide for the crane used for the mounting of the segments, the beam or profile members on erection of the building are caused to form for the crane a continuous track which is extended as each further segment is mounted, and the crane is so adapted that it can perform a continuous upward climbing movement on the outer side of the building. The systm for carrying out the method includes the crane which is adapted to climb upward along the guides on the outer side of the building as the erection of the building progresses. The crane has a bracket structure which is coupled over jack units adjustable in length to a further bracket structure which serves as a movable abutment. Further, latch means are arranged at the two bracket structures to permit the alternate latching thereof to the guides.
A method for erecting a self-supporting tower-like building structure composed of a plurality of superimposable segments, each segment being provided with a vertically extending track secured to its outer periphery for guiding a crane and an associated lifting means for raising the crane to elevated positions along the track, said crane and lifting means being separately movable along the track, comprising mounting at least one of the segments with its attached track at the lowermost position and at the desired location, mounting the crane and lifting means on the track of the at least one lowermost segment with the crane above the lifting means, locking the crane to the track, raising another segment of the building structure with its attached track by the crane onto the previously erected at least one segment so that the track thereon is coextensive and aligned with the track of the erected segments, securing the new segment to the at least one lower segment, locking the lifting means on the track, raising the crane along the track by the locked lifting means a distance substantially equal to the vertical height of the new segment, locking the crane on the track at its new raised position, unlocking the lifting means, raising the lifting means to a position beneath the crane substantially equal to the original distance therebetween, the repeating the steps until the erected building structure has been completed.
