Abstract
The invention discloses a basement tower crane foundation construction method and structure adopting a reverse construction method. The method comprises the steps as follows: a tower crane is directly mounted on a basement roof by means of a permanent basement structure; the basement roof is reinforced by a cross beam; and a tower crane foundation is constructed on the cross beam, and the tower crane foundation, the cross beam and the basement roof are connected into a whole through steel bars. At the early stage of design, permanent basement structure pile foundations, steel pipe columns and the basement roof are utilized, and through reexamination and checking calculation of an original design institute, a tower crane model meeting selection requirements is directly mounted on the basement roof for mounting construction. The basement tower crane foundation construction method and structure adopting the reverse construction method have the advantages as follows: the permanent basement structure is utilized, a tower crane foundation pile and a built-up steel column are omitted, reserved holes in the basement structure are reduced, secondary construction of the basement structure is reduced, the construction period is shortened, the potential safety hazard is reduced, the construction measurement expense is saved, and meanwhile, normal use of the tower crane and safety of the permanent basement structure are guaranteed.

Background technology
along with the development of Building Trade in China, all kinds of types of construction continue to bring out, and the super dark engineering of super large is more and more.In conventional project reverse construction, modal a kind of tower crane mounting means is that tower crane is arranged on the basis of basement bottom board; Also having a kind of mounting means is first by tower crane requirement construction pile foundation, and then basement bottom board adopts laced of battened compression member to top board space, tower crane is raised to basement roof absolute altitude place, and then tower crane is arranged on laced of battened compression member.Above two kinds of methods all need to design separately tower crane pile foundation, reserving hole for tower crane.In basement construction, must strengthen the security protection to reserving hole, have potential safety hazard.After tower crane is removed, all need to carry out the structure secondary construction of tower crane position reserving hole.This practice causes larger waste, does not meet the thinking of energy-saving and emission-reduction.
Summary of the invention
the object of the invention is to, provide a kind of construction method and structure of basement top-down method tower crane, to save the construction period, reduce potential safety hazard, save working measure and take, ensure that tower crane normally uses and ensures the safety of basement permanent structure own simultaneously, thereby overcome the deficiencies in the prior art.
technical scheme of the present invention is achieved in that
the construction method of a kind of basement top-down method tower crane of the present invention is that the method is to utilize basement permanent structure directly tower crane to be arranged on basement roof; Described basement roof is reinforced by nine-squares beam, and the tower crane of constructing on nine-squares beam, and tower crane, nine-squares beam and basement roof are linked to be entirety by reinforcing bar.
in preceding method, described basement permanent structure comprises pile foundation, steel pipe column and basement roof, and its sequence of construction is followed successively by: pile foundation construction, steel pipe column construction, basement roof construction, nine-squares beam construction and tower crane construction; Tower crane is directly installed on tower crane.
the structure of the of the present invention a kind of basement top-down method tower crane building according to said method is that the structure of this basement top-down method tower crane comprises basement permanent structure; Basement permanent structure comprises pile foundation, steel pipe column and basement roof; Basement roof is provided with nine-squares beam, is provided with tower crane in nine-squares beam, and tower crane is installed on tower crane.
in the structure of above-mentioned basement top-down method tower crane, described basement roof is the strong concrete plate that intensity C35P6 thickness is 400mm.
in the structure of above-mentioned basement top-down method tower crane, described nine-squares beam is for being highly greater than 1200mm, and the strong concrete beam identical with basement roof intensity.
in the structure of above-mentioned basement top-down method tower crane, described tower crane intensity is C35 concrete.
owing to having adopted technique scheme, the present invention compared with prior art, the present invention utilizes basement permanent structure pile foundation, steel pipe column and basement roof at the design initial stage, checks checking computations through original design unit, meets the tower crane model selected and is directly installed on and on basement roof, carries out installation.Practice advantage is like this, utilize basement permanent structure, cancel tower crane stake and laced of battened compression member, reduce basement structure reserving hole, reduce the construction of basement structure secondary, save the construction period, reduce potential safety hazard, save working measure and take, ensure that tower crane normally uses and ensure the safety of basement permanent structure own simultaneously.

Detailed description of the invention
below in conjunction with drawings and Examples, the present invention is described in further detail, but not as any limitation of the invention.
the construction method of a kind of basement top-down method tower crane of the present invention, as shown in Figure 1, the method is to utilize basement permanent structure directly tower crane to be arranged on basement roof; Described basement roof is reinforced by nine-squares beam, and the tower crane of constructing on nine-squares beam, and tower crane, nine-squares beam and basement roof are linked to be entirety by reinforcing bar.Basement permanent structure comprises pile foundation, steel pipe column and basement roof, and its sequence of construction is followed successively by: pile foundation construction, steel pipe column construction, basement roof construction, nine-squares beam construction and tower crane construction; Tower crane is directly installed on tower crane.
as shown in Figure 2, the structure of this basement top-down method tower crane comprises basement permanent structure to the structural representation of the structure of the of the present invention a kind of basement top-down method tower crane building according to said method; Basement permanent structure comprises pile foundation 1, steel pipe column 2 and basement roof 3; Basement roof 3 is provided with nine-squares beam 4, is provided with tower crane 5 in nine-squares beam 4, and tower crane 6 is installed on tower crane 5.The strong concrete plate that basement roof 3 is 400mm for intensity C35P6 thickness.Nine-squares beam 4 is for being highly greater than 1200mm, and the strong concrete beam identical with basement roof 3 intensity.Tower crane 5 intensity are C35 concrete.
Embodiment
when concrete enforcement, as shown in Figure 3, this example is applicable to the engineering of three layers of above super dark contrary sequence method of basement.
its principle is to utilize basement permanent structure to carry out tower crane installation.Sequence of construction is followed successively by: pile foundation construction → steel pipe column construction → basement roof construction → tower crane construction → head tower hangs to be installed and uses.Specific construction step is as follows:
1, way is carried out pile foundation 1 and is constructed routinely;
2, way is carried out basement bottom board 7 and steel pipe column 2 is constructed routinely;
3, carry out basement roof 3 by mode of the present invention and construct, concrete steps are as follows:
