technical background

With the development of society, there are more and more super high-rise buildings. The pursuit of building height can no longer meet people's needs, and more people begin to pursue beautiful, novel and graceful shapes of buildings, which makes curtain walls become the first choice of high-end buildings. Standard configuration, it can be seen that the curtain wall construction has become an important node in the whole project. Whether the curtain wall panels are made of aluminum gusset panels, glass curtain wall panels or other materials, they are all large in size and heavy, and can only be installed with the aid of equipment, especially for super high-rise buildings. Difficulties in hoisting and poor safety caused by the shape change.

The hoisting and positioning of the glass curtain wall of traditional super high-rise buildings is mainly carried out by construction elevators. At the same time, the tower crane can also be used for auxiliary hoisting when the tower crane is not dismantled. Waste of tower crane man-hours; when using construction elevators, considering the regular inspection and cost of construction elevators, usually only one or two are installed on the outside of the building, which cannot meet the curtain wall transportation at all, and transport glass to the construction elevator at the same time The curtain wall blocks and the transport from the construction elevator to the location where they need to be installed need to be re-transported, which not only wastes manpower, but more importantly, it is easy to cause damage to the glass curtain wall panels only through manual loading, unloading and transportation.

Patent CN106121255A discloses a super-high-rise Ouli curtain wall installation equipment, including Xie La steel wire, diagonal tie rods, pre-embedded wall parts installed on the multi-layer cavity, bracket connecting bolts, electric hanging baskets, cantilever brackets and other Electric hoist, the two ends of the cantilever bracket are respectively connected to the lowermost pre-embedded wall part and the bracket connecting bolt, the cable-stayed steel wire is connected between the bracket connecting bolt and the uppermost pre-embedded wall part, and the cable-stayed rod is connected to the bracket connection Between the bolts and the pre-embedded wall parts of the middle layer, the electric hanging basket and the electric hoist are connected on the I-beam track on the cantilever bracket. The utility model combines the vertical lifting and horizontal sliding of the glass curtain wall with the electric hoist, although it can improve the comfort and work efficiency of the curtain wall work, but it is only convenient for buildings with regular facades, and it is easy to use for irregular buildings. The installation of the curtain wall on the facade is prone to bumping into walls, and since the tracks are set separately for each side, it cannot solve the problem of hoisting and positioning at the corners of the building.

It can be seen that a device and construction method for super high-rise building glass curtain walls that are cost-effective and can be adapted to different facade structures are extremely important.
