Abstract

The invention relates to a super high-rise core tube internal and external hanging tower crane support beam structure and a construction method thereof. Two parallel horizontal tower crane support girders are arranged, the sections form box shapes, a root part of each girder is connected with a core tube embedded part through a girder ear plate, inclined supports are circular pipes, one end of the inclined support is supported and connected to a core tube, the other end is connected with the vertical tail end of the corresponding girder, one end of a horizontal pull rod is connected to the core tube in an inclined manner, the other end is connected with the horizontal tail end of the corresponding girder, and the two girders are connected by a horizontal connection rod to form a main body frame support system. According to the super high-rise core tube internal and external hanging tower crane support beam structure and the construction method, the structure is simple, a tower crane is externally hung on the outside of the core tube so that influence of structural construction in the core tube is greatly reduced and utilization of the hanging scope of the tower crane is sufficient, the construction is simple, and the cycle is shortened.

Description

technical field

[0001] The invention relates to a construction method for a supporting structure of a core tube tower crane, in particular to a super-high-rise core tube hanging inside and outside a tower crane supporting beam structure and a setting method thereof. Background technique

[0002] At present, as buildings become higher and higher, this makes the vertical transportation of building materials more and more important in the process of building construction, and directly affects the smooth progress and construction period of engineering construction. In order to ensure vertical transportation and reduce economic costs, self-climbing tower cranes have emerged. However, as the height of the building becomes higher and higher, the difficulty of installing the tower crane support beam increases. The previous installation methods can no longer meet the construction requirements. Especially in the installation of super high-rise steel structures, the structural form i...
