The invention discloses a kind of tower crane method to set up being applied on bridge, it is characterised in that the tower crane method to set up comprises the steps：After the concrete placings of lower king-post strut are finished, it is provided for the built-in fitting of tower crane is installed on the top surface of the lower king-post strut；Reinforcing bar and template are installed on the top surface of the lower king-post strut and the concrete placings of upper king-post strut are completed；To eject for connecting the basic component of the tower crane on the built-in fitting of the lower king-post strut top surface, complete the installation of the tower crane afterwards on the basic component.It is an advantage of the invention that construction method is easy, it is easy to operate, construction cost can be effectively reduced.
Description
Technical field
The invention belongs to technical field of bridge engineering, and in particular to a kind of tower crane setting side being applied on bridge
Method.
Background technology
It is for the setting of tower crane, extremely common in Bridges in Our Country is built.In large bridge construction it is especially
Vertical transport is solved the problems, such as, often arranges tower crane to solve the problem.But, the basis of its tower crane typically can all be arranged on
On cushion cap foundation, so relatively more directly perceived, stress is also clearer and more definite.
But, tower crane is set on cushion cap foundation, problems with is typically can be potentially encountered：
1）When the area of cushion cap is unsatisfactory for arranging tower crane, at this moment the side root meeting " falling through " of tower crane, can be used outstanding
Choose interim bracket on suspended deck structure side to solve；Or the interim pile foundation of injection is processing；
2）When lower king-post strut is higher, it is the column stabilizing measures for solving tower crane, sometimes between lower king-post strut and tower crane pier shaft
Temporary rod system is set.Built-in fitting to be set between concrete column, detrimental effect is brought to the presentation quality of concrete column；
3）When bridge floor design is more wide, original structure design can be typically " vase " style column superstructure design,
To meet the stable needs of cross-section of bridge；So, the setting to tower crane brings certain difficulty.
Therefore, it is not very high structure to superstructure, while needing tower crane to solve the problems, such as vertical transport, is protecting
Under the precondition of safety, high-quality, it is quick, economically realize job site Perpendicular Problems, becoming construction technical staff needs solution
Problem certainly.
The content of the invention
The purpose of the present invention be according to above-mentioned the deficiencies in the prior art in place of, there is provided a kind of tower crane base being applied on bridge
Plinth method to set up, the tower crane method to set up reduce tower crane tower by by the basis instrument of tower crane in the top surface of lower king-post strut
The sections of body, reduces operating expenses.
The object of the invention is realized being completed by technical scheme below：
A kind of tower crane method to set up being applied on bridge, it is characterised in that the tower crane method to set up includes
Following steps：After the concrete placings of lower king-post strut are finished, it is provided for the built-in fitting of tower crane is installed on the top surface of the lower king-post strut；
Reinforcing bar and template are installed on the top surface of the lower king-post strut and the concrete placings of upper king-post strut are completed；By positioned at the lower king-post strut top surface
Eject on built-in fitting for connecting the basic component of the tower crane, complete the peace of the tower crane afterwards on the basic component
Dress.
The lower king-post strut is made up of vertically arranged column and level to the side binder and middle binder that arrange, the tower crane
Supporting is installed on the side binder and the middle binder.
The basic component constitutes interim positioning by welding iron plate.
It is an advantage of the invention that（1）Solve on the basis of tower crane is arranged at cushion cap concrete or encorbelment on cushion cap foundation
Performance difficulty problem during " bracket " structure, it is economical and practical；（2）Tower crane is solved because cushion cap area is not enough arranged, and is made
The operation at sea of tower crane is set with interim injection pile foundation, construction cost is advantageously reduced by reducing operation at sea；（3）
As tower crane is arranged on the top of concrete column, reduce the sections of tower crane tower body, i.e., the tower body in the range of the stem height,
As the position for arranging is improved, the tower body structure of this section is reduced, the lease expenses of equipment is reduced.
Description of the drawings
Fig. 1 is 1/2 lower king-post strut top floor map in the present invention；
Fig. 2 is the positive elevational schematic view of 1/2 lower king-post strut in the present invention.
Specific embodiment
The feature and other correlated characteristics of the present invention is described in further detail by embodiment below in conjunction with accompanying drawing, with
It is easy to the understanding of technical staff of the same trade：
Such as Fig. 1-2, in figure, labelling 1-6 is respectively：Column 1, side binder 2, middle binder 3, built-in fitting 4, tower crane 5, lateral and
Diagonal brace 6.
Embodiment：As shown in Figure 1, 2, the present embodiment is specifically related to a kind of tower crane setting side being applied on bridge
Method, the bridge are the short tower girder stayed-cable bridge of six tower single cable planes, and full-bridge has 6 king-towers, and each king-tower substructure tower body is highly
21-25M, two-by-two symmetrically, king-post top is made up of 2 road binders.
The tower crane method to set up by by the basis instrument of tower crane in lower king-post strut top surface to simplify construction method, and
Construction cost is reduced, following steps are specifically included：
（1）The concrete placings of lower king-post strut are completed, lower king-post strut is made up of column 1, side binder 2 and middle binder 3, twice side binder
2 are symmetricly set in 3 both sides of middle binder, and three's horizontal cross is connected between twice vertical upright column 1；Install in lower king-post strut top surface
Pour the reinforcing bar and template needed for upper king-post strut；It is respectively provided with built-in fitting 4 afterwards on side binder 2 with middle binder 3, built-in fitting 4 has
Body is the iron plate that welding is embedded on 3 side of side binder 2 and middle binder in advance；
It should be noted that these built-in fittings 4 some be to be welded or prefabricated in factory or concentrated processing place,
During in-site installation, not weld with all kinds of reinforcing bars in column 1, side binder 2 and middle binder 3, to avoid affecting lower king-post strut main body
The intensity of structure；
（2）The concrete placings construction of upper king-post strut is completed, the intensity and elastic modelling quantity of upper king-post strut must reach wanting for concrete structure design
Ask；
（3）Eject on default built-in fitting 4 before for connecting the basic component of tower crane, i.e. lateral and diagonal brace 6, and profit
Temporary weld positioning is carried out with iron plate；
（4）The erecting and welding of tower crane 5 is completed according to the design drawing of tower crane 5；
（5）According to the administrative provisions of special equipment, carry out situ loading, and submit a report asking for relevant department carrying out an acceptance inspection.
The present embodiment has the characteristics of safe and reliable, construction is convenient, economical and practical, specifically includes following beneficial effect：
（1）Solve on the basis of tower crane is arranged at cushion cap concrete or encorbelment on cushion cap foundation " bracket " structure when reality
Difficult problem is applied, it is economical and practical；
（2）Tower crane is solved because cushion cap area is not enough arranged, and tower crane is set using interim injection pile foundation
Operation at sea, by reduce operation at sea advantageously reduce construction cost；
（3）As tower crane is arranged on the top of concrete column, the sections of tower crane tower body is reduced, i.e., in stem height model
Tower body in enclosing, as the position for arranging is improved, reduces the tower body structure of this section, reduces the lease expenses of equipment.
