This engineering tower crane plan view is as shown in Figure 7.By Fig. 7 it can be seen that every main building is configured with Liang Taita
It hangs, podium is whole all in tower crane lifting range, can carry out podium construction while ensure that high building construction.According to this engineering
Main building is divided into two flowing water sections by fabricated construction deployment, two tower cranes, i.e. a tower crane is responsible for left side flowing water section component and is hung
Dress, the shuttering supporting that another tower crane is responsible for right side are set up to bind with laminated floor slab reinforcing bar and construct, and work holdup phenomenon is avoided.Together
When, road arrangement is circumferential highway in field, and stockyard is arranged near main building, while in tower crane covering surface.It both avoids in this way
The situation that a large amount of components block up when marching into the arena also avoids the case where appearance of separate unit tower crane can not unload.
The comparison of tower crane attachment anchoring and scheme are selected.The attached form of tower crane is as shown in Figure 8, comprising: tower crane attachment in
Structural column, tower crane attachment are in Vierendeel girder side and tower crane attachment in frame back.
The comparison of tower crane attachment form is as follows: (1) the first tower crane attachment in structural column form is made in cast-in-place structural
With a kind of attached form the most universal.(2) second of tower crane attachment are the optimization based on the first in Vierendeel girder side form, excellent
Point has cantilevered structure in structural column, but this engineering main building outermost in avoiding drawknot, this attached form need to be in overhanging secondary beam
Upper indwelling construction joint has certain influence to cantilevered structure, at the same the later period need to spend it is more manually and the time is to constructing herein
Seam is repaired.(3) the third tower crane attachment is the optimization based on second in frame back, advantage in avoiding drawknot in
Structural column, while the problem of avoid the indwelling construction joint at cantilevered structure.
The ratio choosing of tower crane attachment form and grouting form are close not in fabricated construction in the work of tower crane attachment formal character
It can divide, i.e., live grouting form determines tower crane attachment anchor type.
Grouting is divided into following two kinds of forms in the selection work of grouting form: when layer grouting is in the milk with interlayer.When layer is in the milk
It is in the milk immediately after the completion of prefabricated post lifts, the advantages of such mode is that structural column is connect with floor plates and more may be used
It leans on, certain upper load can be carried.Disadvantage is that grouting construction is the key of progress monitoring during main structure construction
Node exists simultaneously interchange operation, there is some potential safety problems.Interlayer grouting is i.e. to pre- before shuttering supporting framed bent is removed
Cylinder processed carries out grouting construction, as shown in Figure 9.The advantages of such mode, is, although grouting construction is as progress key node
But it can be interspersed in main structure construction, as two-level node even three-level node, not influence the whole duration, and there is no vertical
Body crossed construction；The disadvantage is that, reinforcing bar and cushion block are only leaned in the connection of column and substructure before grouting construction, top is most of
Load is supported by supporting row frame.The construction of final choice interlayer grouting.
The grouting form based on interlayer grouting is again to three kinds of attached forms of tower crane in the selection work of tower crane attachment form
It carries out than choosing.The first attached form, when carrying out tower crane attachment, in-situ precast column is not in the milk, therefore, tower crane attachment
In there are biggish security risks in the prefabricated post not being in the milk；Second of attached form, need to overhanging secondary beam on indwelling construction joint,
There is certain influence to cantilevered structure, while the later period needs to spend and more manually repair with the time to construction joint herein；The
Three kinds of attached forms, attachment stress are undertaken by entire Core Walls Structure floor system, and prefabricated post and framed bent are subjected only to minimum part power,
The security risk for avoiding the first attached form has also evaded influence of second of attached form to cantilevered structure.Therefore,
In conjunction with this project actual conditions, final choice tower crane attachment is in the construction of frame back.
Tower crane plays an important role during prefabricated concrete structure prefabricated part hanging, and prefabricated components are main
Lifting, installation, correction rely on tower crane completion, therefore, the type selecting of tower crane, arrangement and adhere to the selection of anchor type and directly affect
The construction deployment and construction speed of entire project.Operating radius, maximum prefabricated components lifting capacity, tower are combined during type selecting
It hangs position and attached form etc. to comprehensively consider, matches grouting form and attached form, then match the grouting being in the milk using interlayer
Form and tower crane attachment are in the attached form of frame back.Interlayer grouting is as progress key node but can be interspersed in main body knot
In structure construction, the whole duration is not influenced, and there is no crossings on different level to construct, tower crane attachment is attached in the attached form of frame back
Stress undertaken by entire Core Walls Structure floor system, prefabricated post and framed bent are subjected only to minimum part power.Overcome in the prior art
The problems such as unbalanced between the inefficiency of simple-arranged tower crane, lifting operation region, have that tower crane is high-efficient, lifting operation area
The high advantage of equilibrium degree between domain.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
