Description
Technical field
The present invention is a kind of observation platform device suitable for Large Span Bridges girder steel construction survey, and it is auxiliary to belong to engineering survey
Help engineering device technique field.
Background technique
During the main bridge steel girder erection of Long span, construction survey and monitoring measurement work are particularly critical, often direct relation
To the success or failure of engineering.Presence of the observation platform not only as measurement control point is measured, but also provides space and platform for measurement work,
It is the important foundation for carrying out measurement work.The main bridge steel truss erection of existing engineering highway and railway bi-purpose cable-stayed bridge, since bank controls
Point angle and visual field condition are poor, are unfavorable for the development of girder steel construction survey work, and construction site situation is complicated, and measurement is limited by condition
System should not set the method that station is observed using at bank control point.Earlier measurement method is by multiple turning point or repeatedly friendship
Instrument, is erected at girder steel and newly sets up on internode and measure by meeting, and field measurement effect reflection, this mode measures workload
Greatly, low precision, data integrity are poor.
Summary of the invention
Proposed by the present invention is a kind of observation platform device suitable for Large Span Bridges girder steel construction survey, and purpose exists
In overcoming in-site measurement operation difficult, measurement accuracy is poor, and the low problem of working efficiency, the present invention can be within the limited time
Rapidly and accurately complete a large amount of main bridge girder steel construction survey work.
Technical solution of the invention: a kind of observation platform device suitable for Large Span Bridges girder steel construction survey,
Including to mid-game 1, center steel-pipe pile 2, centering pier 3, guardrail 4, platform 5, frame leg 7, staircase 8, the wherein welding of 5 lower surface of platform
There are frame leg 7 and support 6, platform 5 leads to ground by staircase 8, and 5 upper surface of platform is surrounded by guardrail 4, and center is equipped with central steel
Tubular pole 2, installation center operating platform, the upstream and downstream of the center operations platform are respectively fixedly welded a forced centering pier 3, force
Forced centering plate 1 is installed at the top of centering pier 3.
The diagonal brace 6 is mounted between frame leg 7, plays reinforcement effect.
The observation platform device is welded on Main Pier of Bridges girder steel center, is set at pier top internode.
The long 2m of the observation platform device, width 2m, high 4.5m, the pressure pair of the upstream and downstream welding of Platform center operating platform
Middle pier is 1.2 meters high.
The observation platform device uses full steel structure.
Beneficial effects of the present invention:
1) observation platform is arranged at main pier pier top internode, and solid firm, Platform Designing stability is strong, and guarantee sets website stability series
Number is substantially reduced compared to setting at the end bay internode of station because of factors bring measurement errors such as girder steel shake and construction infections.For
It measures work and the reliable control point of most convenient and measuring condition is provided, greatly improve the precision and efficiency of measurement work.
2) i.e. customizable in steel construction processing factory, project management department using project current material, it is good and cheap, it is practical, it is economical
Type is good, is conducive to promote the use of in practice.
3) podium level is high, can cross girder steel itself and block, measurement control point of the backsight to setting on the coast.When observation
Construction equipment and heap loading on girder steel are crossed, the visual field is good, reduces the probability that measuring point blocks.
4) platform upstream and downstream is provided with two forced centering piers, and screening of the middle purlin to measurement sight can be avoided when setting up instrument
Gear sets station upstream when observing upstream measuring point, station downstream is set when observing downstream measuring point.The sight of all measuring points can be completed by setting station twice
It surveys.
