Description
Technical field
Climbed technical field of construction the present invention relates to inside-climbing tower crane, and in particular to a kind of large-scale swing arm tower crane of high-rise building
Original position is converted to plug-in construction method by interior climb.
Background technology
Tower crane is as most important vertical transport instrument in Construction of High-rise, and the vertical transport instrument in high-building construction is most
Frequently with for outer attached self-standing crane, but because being limited by standard section of tower crane after depth of building is more than 200m
Outer attached derrick crane can not meet needs of constructing, simultaneously as the smaller influence in view of group towers work of Core Walls Structure.Therefore superelevation
Change in layer construction in use and climb arm tower crane, arm tower crane of inside creeping is that one kind is arranged on interior of building elevator or building
Tower crane between ladder, it can progressively be climbed upwards with construction progress.Arm tower crane of inside creeping needs three sets of load-bearing in work progress
For girder steel to form support system, most lower one of girder steel is used for load-bearing, and up one of girder steel is used for fixed tower and offset by the level of power
Influence.It is most upper together in the construction of building concrete masterplate to being used in turn when needing to climb again below tower crane, by the section that climbs,
Jacking cylinder, climb band and change step successively and reach the purpose that makes tower crane integrally climb.
Because the most important condition of tower crane climbing finishes for most upper one of steel girder erection, therefore girder steel has bad luck work and seems extremely heavy
Will.Simultaneously because the high-level structure construction period is more and more tighter, traditional method is to have bad luck girder steel using another tower crane auxiliary
Work, but also take the normal of another tower crane and have bad luck the time and hang time, cause when tower crane is constructed, two tower cranes can not be simultaneously
The problem of construction, tower crane is caused efficiently to be used and the technical problem such as claim for eot.
Constructed in addition, ultra-large type swing arm tower crane is continued on in each Super High.Ultra-large type movable arm tower suspender have from it is great,
The characteristics of single lifting capacity is big, large arm elevation angle height etc.；When rising to hundreds of meters of high space-times, ultra-large type swing arm tower crane can produce huge
Vertical load and horizontal loading.In order to resist the support of huge vertical and horizontal loading, at present ultra-large type boom-type tower crane
System has generally comprised main support crossbeam, secondary beam and brace etc..It is common mainly by two that wall-attaching equipment is climbed in existing tower crane
The support beam be arrangeding in parallel between two wall bodies to be located with setting the C-type steel of tower crane to collectively form；Wherein, the support beam
Both ends by being welded with the pre-buried steel corbel that is fixedly arranged on wall, so as to be attached on wall.
It is worth noting that, as high-rise building constantly breaks through new high degree, structure type is from tube-in-tube structure to bundled tube
The development of structure, bundled-tube structure constantly contract mistake with the rise of building, at tower crane positioning the contracting of structure lose and necessarily result in tower crane
The affected missing of vertical applied force point, and the difference for having that the contracting of single wall is lost, the contracting of double walls is lost, the contracting of three walls is lost is lost in bundled tube contracting, contracting is lost again
It is layered and stage by stage, causes the attachment point contractings of tower crane needs and lost or do not contracted and lose wall and the problem such as hinder.Meanwhile beam
The small space of barrel structure also results in inside-climbing tower crane support system and has bad luck difficulty.
The content of the invention
In view of the foregoing, the present invention provide a kind of large-scale swing arm tower crane original position of high-rise building by it is interior climb be converted to it is plug-in
Construction method, with climbed in solution operating mode support system have bad luck it is difficult, have bad luck more than rod member quantity caused by have bad luck speed slowly, work
The technical problems such as phase extension, reach and be easy to tower crane being converted to plug-in, raising integral construction benefit by interior climb in situ.
To achieve the above object, the present invention, which adopts the technical scheme that, provides a kind of high-rise building large-scale swing arm tower crane original
Position is converted to plug-in construction method by interior climb, when the tower crane climbs operating mode inside between the interior wall and exterior wall of Core Walls Structure；Its
