Description
Technical field
The present invention relates to municipal construction fields, and in particular to a kind of steel-structure box girder analogy method.
Background technique
With the development of China's steel and iron industry and long strands, the quantity of steel construction municipal administration bridge is being continuously increased, case
Tee section has light-weight, and overall performance is good, and structure is beautiful, industrialized production degree is high, speed of application is fast, under-clearance is big etc.
Advantage, so that steel box girder is widely used in municipal Bridge Design and building course.At the same time, municipal steel case
The features such as complexity of beam construction environment, the diversity of functional requirement, large span, brings very to its production, installation and construction
It is different from the technical problem of railway, highway steel box girder construction more.Wherein, especially prominent is how to ensure completed region of the city just
Large-tonnage steel box beam is lifted in narrow construction space under the conditions of normal open row, under complicated structures environmental condition.
Summary of the invention

Key point is monitored；Numeral input is produced to new simulation into program according to the practical situation that changes, while adjusting the later period to apply
Work makes integral construction final result according to optimal generation.
Compared with the prior art, the invention has the following beneficial effects: BIM technology and numerical simulation is based on, using wireless
Transmission technology, selection is able to reflect steel box-girder virtual condition, the key point of control steel box-girder safety is monitored, thus in time,
Accurately understand the internal force deformation of hoisting process central sill piece and the stress variation of suspension procedure structure.By dividing monitoring data
The grasp of analysis and changing rule instructs steel box-girder suspension installation overall process, it is ensured that construction is gone on smoothly.
Further advantage, target and feature of the invention will be partially reflected by the following instructions, and part will also be by this
The research and practice of invention and be understood by the person skilled in the art.
Specific embodiment
In order to make the present invention realize technological means, creation characteristic, reach purpose and effect more clearly and be apparent to,
The present invention is further elaborated With reference to embodiment:
The invention proposes a kind of steel-structure box girder analogy method, includes the following steps 1), found steel case mould, including skeleton is built
Mould, the modeling of box beam shell and the modeling of box beam diaphragm plate, locating framework integrally catch on model, steel case for parameterizing change steel box-girder
Beam axis states formula by line number or flat ordinate fit approach creates, and the shell of box beam includes top plate and bottom plate and side plate, is passed through
Knife curved surface in model space creation diaphragm plate all directions, to cut diaphragm plate blank mould；2), secondary open is carried out using software
Hair, implementation model quickly generate, secondary to software progress using VB language on the basis of summarizing the modeling of traditional-handwork steel box-girder
Exploitation, establishment steel box-girder automatically generate plug-in unit, and implementation model quickly generates；3), modeling personnel are right in program for convenience
Process is monitored and scheme modifying, and steel box-girder is generated 3D axis, horizontal curve, crucial cross-sectional sketch and steel box-girder by program；4),
Program is automatically performed the whole of steel box-girder model and establishes；5), selection optimal result installation, while during the installation process in real time to pass
Key data is updated.
It determines truss installa-tion, temporary support and segmentation installation in conjunction with simulation as specific embodiment, is installed using segmentation,
And determine the space coordinate of each segmenting unit, then guarantee configuration and the spatial position of steel box-girder.
Simultaneously the invention proposes a kind of steel-structure box girder installation method, include the following steps,
1), construction material equipment prepares；It selects according to the actual situation and drives bridge machine, crane, portal frame, beam car, electric welding
Machine, wirerope and guide chain cucurbit
2), box girder transport；Box beam is lifted by crane using wirerope and then slings steel box-girder from the beam pedestal of storage, is then utilized
Portal frame is sent to beam car, is sent at Bridge Erector by beam car, and kickboard, the track laying of beam car are parked around Bridge Erector
To kickboard, box beam is directly placed using kickboard, facilitate expansion box beam stacks area, and a corral column is arranged around kickboard
Realize that kickboard is separated with surrounding water, there are water-heads for water and the outer water of fence in fence, with being continuously increased simultaneously for placement box beam
The water extracted in fence makes its water level decreasing, flushes the box beam of the top with track always；
3), pile equipment, including every beam and support center line, pinner and support inspection, equipment inspection are released, then press
It according to equipment and tries to hang, then feeding beam, hanging beam, fall beam, telephone-moving；Using BIM technology and digital simulation, it is practical to choose reflection steel box-girder
State, each feeding beam and examination hang after by data feedback to program, calculate best stress point herein using digital simulation, and control
Box beam safety-critical point is monitored；There is error since actual conditions inevitably have design, so again according to reality before every section of construction
Border change situation numeral input is produced to new simulation into program, while adjust construction in later period make integral construction final result by
According to optimal generation；Its total design of construction simulation adjusted is constant.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered at this
In the scope of the claims of invention.
