Description
Technical field
The present invention relates to municipal steel construction CONSTRUCTION OF CABLE-STAYED BRIDGE technical fields, and in particular to the installation of cable-stayed bridge anchor tie plate
Control method.
Background technique
Cable-stayed bridge anchor tie plate is connect in steel girder top surface with Main Girder Welding, is the pass of stay cable of cable-stayed bridge and the transmitting of beam body power
Key component, positioning accuracy request are very high.Since position of the anchor tie plate on girder is relatively fixed, to guarantee its installation accuracy, with
And it saves subsequent installation process and is integrally machined anchor tie plate and girder usually when processing steel girder beam.But one is also brought in this way
Determine problem, since girder is in the unified processing of processing space, the girder overall height for having installed anchor tie plate is higher, past from processing space
When girder is transported in erecting bed, the municipal cable-stayed bridge in urban district is located to construction location, the total height of girder steel haulage vehicle is frequent
It is limited by limit for height an outpost of the tax office or limit for height channel bridge, can not be successfully passage；Since anchor tie plate is fixed in advance with girder, in installation steel
If there is deviation when girder, the position deviation of anchor tie plate is also resulted in, influences the positioning accuracy of anchor tie plate.
Summary of the invention
The object of the present invention is to provide a kind of steel construction cable-stayed bridge anchor tie plate field installation process, by steel girder and anchor
Pulling plate separately transports, and to reduce the height of transport vehicle, avoids in the current limited and risk in transit in urban district, while installing anchor at the scene
Anchor tie plate installation site can be checked when pulling plate, improve its positioning accuracy.
Technical scheme is as follows:
A kind of steel construction cable-stayed bridge anchor tie plate field installation process, it is characterised in that the following steps are included:
(1) all steel box-girders of cable-stayed bridge processing space after processing is completed, carry out steel box-girder it is pre-splicing, when steel box-girder is pre-splicing according to
Design installation site of the anchor tie plate on steel box-girder carries out anchor tie plate prepackage, and the installation control of anchor tie plate is marked on steel box-girder
System point and position baseline, the installation control point are the axis of anchor tie plate cable guide pipe and the intersection point of steel box-girder top surface, described fixed
Position reference line is orthographic projection line of the anchor rope conduit axis on steel box-girder；
(2) steel box-girder and anchor tie plate are transported to construction site respectively；After steel box-girder is installed, full-bridge closes up, according to oblique
Cable setting angle installs control point to anchor tie plates all on steel box-girder and position baseline carries out repetition measurement, and according to multiple
Survey installation control point and position baseline that result redefines anchor tie plate；
(3) anchor tie plate component is transported on steel box-girder, it is mobile with jack pushing tow anchor tie plate, make anchor tie plate base plate center line
It is overlapped with the position baseline on steel box-girder, the axis extended line of anchor tie plate cable guide pipe and the intersection point of steel box-girder top surface and installation are controlled
System point is overlapped；
(4) plumb line that setting intersects vertically with cable guide pipe axis orthographic projection line in anchor tie plate upper end, uses flower basket bolt
Or chain block adjusts anchor tie plate angle, until plumb line is directed toward the position baseline of steel box-girder top surface, realizes anchor tie plate
Positioning；
(5) the above-mentioned positioning states of anchor tie plate are kept, while anchor tie plate bottom plate and steel box-girder top surface being welded and fixed, are completed
Anchor tie plate in-site installation.
The present invention is by anchor tie plate and steel girder split production and transport, it is possible to reduce the height of anchor tie plate beam section makes steel master
Whole height reduces when beam transports in urban district, avoids beam section transport superelevation, transfinites；After the completion of steel erection of main beam, scene
Carry out anchor tie plate measurement and positioning and installation, it can be ensured that the positioning accuracy of anchor tie plate.
Detailed description of the invention
Fig. 1 is construction process figure of the invention；
Fig. 2 is anchor tie plate along bridge to mounting structure schematic diagram.
Specific embodiment
Construction process of the invention is as shown in Figure 1, detailed process is as follows:
All steel box-girders of cable-stayed bridge processing space after processing is completed, carry out steel box-girder it is pre-splicing, according to anchor when steel box-girder is pre-splicing
Design installation site of the pulling plate on steel box-girder carries out anchor tie plate prepackage, and the installation control of anchor tie plate is marked on steel box-girder
Point and position baseline, the installation control point are the axis of anchor tie plate cable guide pipe and the intersection point of steel box-girder top surface, the positioning
Reference line is orthographic projection extended line of the anchor rope conduit axis on steel box-girder.
Steel box-girder and anchor tie plate component are transported to construction site respectively.After steel box-girder is installed, full-bridge closes up, according to rope
The design setting angle of the anchor point of suspension cable and suspension cable on tower installs control point and positioning to anchor tie plates all on steel box-girder
Reference line carries out repetition measurement, and installation control and the position baseline of anchor tie plate are redefined according to repetition measurement result.
As shown in Fig. 2, anchor tie plate 1 is transported on steel box-girder 2, it is mobile with jack pushing tow anchor tie plate, make anchor tie plate bottom plate 3
Center line be overlapped with the position baseline on steel box-girder, the friendship of axis 5 extended line and steel box-girder top surface of anchor tie plate cable guide pipe 4
Point is overlapped with installation control point 6.
The plumb line 7 that setting intersects vertically with 5 orthographic projection line of cable guide pipe axis in 1 upper end of anchor tie plate, uses flower basket bolt
Or chain block adjusts anchor tie plate angle, until plumb line is directed toward the position baseline of steel box-girder top surface, realizes anchor tie plate
Positioning.
The above-mentioned positioning states of anchor tie plate are kept, while anchor tie plate bottom plate and steel box-girder top surface being welded and fixed, complete anchor
Pulling plate in-site installation.
