Description
Technical field
It is sliding along the vertical-lift of shaped form alien invasion and level that the utility model belongs to high-rise building glass curtain wall unit body
Move the technical field of construction, specially a kind of irregular alien invasion glass curtain wall positioning apparatus of high-rise building.
Technical background
With social development, high-rise building is more and more, and the pursuit in building height can not meet people's need
Ask, and the profile for more starting to pursue building is beautiful, novel and beautiful design, this causes curtain wall into high-end building
Standard configuration, it is seen that curtain wall construction becomes an important node in whole engineering.No matter curtain wall plate is aluminum-pinch, glass curtain wall
Plate or other materials, have size it is larger, from great, auxiliary installation can only be carried out by equipment during installation, particularly with super
With greater need for the lifting in view of being brought by building height and variable topographies is difficult and the problem such as security difference for skyscraper.
The lifting of conventional ultra high layer building glass curtain wall is mainly transported using construction elevator in place, while also can be in tower
Hang and carry out auxiliary lifting using tower crane in the case of not removing, lifting one piece of block of needs in place using tower crane is carried out, and lifting is in place
The man-hour of tower crane can greatly be wasted;When being transported using construction elevator, it is contemplated that construction elevator needs periodic inspection and cost
Problem, one or two only generally is set in the outside of building, can not meet that curtain wall transports at all, while into construction elevator
Transport glass curtain wall block and from construction elevator to needing position transport to be mounted to be required to carry out secondary transhipment, not only waste people
Power, it is often more important that the damage of glass curtain wall plate is only easily caused by manual handling and transport.
Patent CN106121255A discloses a kind of Super High Ou Li curtain walls installation apparatus, including thanks to steel wire, tiltedly
Pull bar, the pre-buried wall-connecting piece on multi-layer cavity, support connecting bolt, driven hanging basket, cantilever supporting frame and wherein electronic calabash
Reed, the both ends of cantilever supporting frame connect undermost pre-buried wall-connecting piece and support connecting bolt respectively, and oblique pull steel wire is connected to support
