Schematic diagram in tower crane.The tower crane includes that embedded foundation section 1, default basis strengthen section 2 and standard successively from bottom to top
Section, embedded foundation section 1 is fixed on the tower crane of bottommost, used as the support base of whole tower crane bottommost, the tower of bottommost
Hang basis high with the top mark of lower section building identical, support is played to whole tower crane.Strengthen section 2 and pre-buried base in default basis
Plinth section 1 is fixedly connected, and the rigidity that section 2 is strengthened on embedded foundation section 1 and default basis is larger, to the standard knot and other structures on top
Effectively support.
Embedded foundation section 1 and default basis strengthen section 2 and constitute first bases, the tower crane structure that the utility model is provided except
Outside including first base, also including second base, second base is located on first base, including the second base section 3 and the
Section 4 is strengthened on two bases, and the second base section 3 is located on first base, and can as the tower crane support base of its upper section, the
The top that section 4 is arranged at the second base section 3 is strengthened on two bases, and both are directly fixedly connected.Second base section 3 and the second basis add
Standard knot is set between the second base and first base of the strong composition of section 4, namely according to order from bottom to top, is included successively：
Embedded foundation section 1, default basis strengthen section 2, standard knot, second the 3, second basis of base section and strengthen the standard of section 4 and more top
Section.The wherein base section 3 of embedded foundation section 1 and second can be supported as tower crane support base to whole tower crane.
The tower crane provided using the utility model, in the architecture construction different to two or more bottom absolute altitudes, will most
The tower crane of bottom is arranged on top mark relatively low architectural plane high, and embedded foundation section 1 is fixed on the tower crane of bottommost
On, 2 pairs of whole tower cranes of section are strengthened by embedded foundation section 1 and default basis and is supported, carry out the relatively low building of bottom absolute altitude
Construction.Treat to carry out backfill operation after the completion of Underground Construction, the tower crane structure by the second base section below 3 is buried, backfill
Concrete is poured into a mould after completion at the second base section 3, the second tower crane is set, tower crane is entered on the second tower crane
Row jacking, is now supported by the second base section 3 to tower crane.Realize that the secondary of tower crane is used with this, do not removing tower crane
In the case of be applied to bottom absolute altitude architecture construction higher.Low cost, more than half is saved relative to traditional form of construction work
Expense；Security is higher, is equal to the normal tower crane for using, the performance of tower crane all the time in tower crane work progress
And the situation of tower crane does not change.
Generally, tower crane is only used for two kinds of different buildings of bottom absolute altitude and is constructed, therefore the He of the second base section 3
The quantity that section 4 is strengthened on second basis is respectively provided with one group, i.e., in addition to embedded foundation section 1 and default basis strengthen section 2, up
One the second base section 3 is only set and section 4 is strengthened on one second basis, there is dual tower crane with this.As shown in figure 3, being
The tower crane structure overall structure diagram on dual basis.
When setting, highly identical high with secondary tower crane top mark in the middle part of the second base section 3.Namely such as Fig. 4 institutes
Show, secondary tower crane top mark horizontal line high is located at the centre position of the vertical direction of the second base section 3.Second base section 3
Top half is protruded upward, such that it is able to pour into a mould concrete in its periphery.Specifically, the periphery of the second base section 3 can be set
Formwork for placing, the tower crane of after-pouring second is completed in backfill, and the periphery of the second base section 3 is provided for marking casting position
Mark, the position for determining cast.As shown in figure 5, including be coated and fixed for the second base section 3 by the second tower crane.
Further, in the utility model the second base section 3 and the second basis strengthens section 4 includes multiple cuboid frameworks
Structure, the second base section 3 at least includes two sections of base sections, and every section of size of base section is to be set in 2m*2m*7.5m, main chord
The round steel of diameter 80mm.Section 4 is strengthened on second basis at least includes six sections of reinforcement sections, and the size for strengthening section is 2m*2m*3m, main string
The round steel of diameter 50mm is set in bar.The size of standard knot is 2m*2m*3m, and round steel is not provided with standard knot, all standard knots
Diagonal web member is that channel-section steel is back-to-back to be welded.Base section mentioned here and reinforcement section refer both to a framework knot for cuboid
Structure.
When tower crane is designed, according to the actual conditions at scene, the absolute altitude of adjustment middle part base section, by changing standard knot
It is high that number adjusts secondary tower crane top mark.The construction of the tower body of whole tower crane is except normal embedded foundation section 1, default basis
Strengthen section 2, standard knot, stock etc., be also additionally arranged the second base section 3 and section 4, the second base section 3 and second are strengthened in the second basis
Basis is strengthened the standard knots that section 4 also serves as tower crane in early stage and is used, namely is used as support base by embedded foundation section and carries out
During support, the effect of the second base section 3 and the second basis reinforcement section 4 is identical with normal standard knot, in the conduct of the second base section 3
During support base, whole tower crane is strengthened section 4 and is supported by the second base section 3 and the second basis.
In polycrystalline substance colligation tower crane reinforcing bar, install tower crane template and embedded foundation section 1 after, start to pour tower
Hang the concrete on basis.After concrete strength reaches design strength, carried out according to tower crane installation specification and the scheme of formulation
The installation of tower crane.
Tower crane proceeds by backfill after the completion of Underground Construction.Returned using plain concrete according to design requirement
Fill out, be backfilled to the tower crane bottom absolute altitude that middle part sets tower crane position.
After backfill is completed, in the reinforcing bar of the periphery colligation tower crane of the second base section 4, the mould of tower crane is installed
Plate, pours the concrete of tower crane.
After the tower crane concrete strength for pouring for the second time reaches design strength, tower is carried out according to actual demands of engineering
The jacking hung.
