Platform.
The utility model adopts the following technical scheme that to solve technical problem：
Slidably construction operation platform is structurally characterized in that for the utility model steel box-girder flange area：By top truss, vertically
Truss and bottom truss are fixedly connected into " C " the type component of opening towards steel box-girder side, and the top truss is in steel
The top in box beam flange area, the bottom truss are located at the lower section of steel box-girder flange area, are set in the bottom surface of the top truss
Multigroup pulley, " C " the type component chooses the top surface of arm using pulley support in flange area, and can be chosen using pulley in flange area
Moved along the bridge on arm；Shaped steel scaffold board is equipped with the bottom truss as construction operation platform.
The design feature of the utility model steel box-girder flange area slidably construction operation platform is lain also in：The top purlin
Frame, vertical truss and bottom truss are formed by the weldering of channel-section steel group.
The design feature of the utility model steel box-girder flange area slidably construction operation platform is lain also in：In the top purlin
Between frame, vertical truss and bottom truss, it is welded to connect using fixation, or be connected by screw bolts.
The design feature of the utility model steel box-girder flange area slidably construction operation platform is lain also in：In the vertical purlin
Oblique drawbar is set between the rod member in the both sides montant and bottom truss of frame on correspondence position, forms reinforcement structure.
The design feature of the utility model steel box-girder flange area slidably construction operation platform is lain also in：In the vertical purlin
The outside of frame is provided with vertical cat ladder.
The design feature of the utility model steel box-girder flange area slidably construction operation platform is lain also in：In the bottom purlin
Frame is surrounded by railing.
Compared with the prior art, the utility model has the beneficial effect that：
1st, the utility model operating platform is simple in construction, and materials are few, and involved material is conventional shaped steel, and feeding is held
Easily, make simple；Only need a loop wheel machine lifting can be in place by its Fast Installation, polyvinyl chloride is convenient.
2nd, the utility model operating platform relies solely on artificial passage in work progress can meet that full-bridge flange area is constructed
Needs, be advantageous to accelerating construction progress.

Fig. 1 is the utility model facade main structure diagram；
Fig. 2 is Fig. 1 side view；
Fig. 3 is Fig. 1 plan；
Label in figure：1 top truss, 2 vertical truss, 3 bottom truss, 4 pulleys, 5 steel box-girder flange areas, 6 scaffold boards, 7
Oblique drawbar, 8 cat ladders, 9 railings, 10 steel box-girders, 11 flange areas choose arm.
Embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, the structure type of steel box-girder flange area slidably construction operation platform in the present embodiment
It is：" C " type of opening towards the side of steel box-girder 10 is fixedly connected into by top truss 1, vertical truss 2 and bottom truss 3
Component, top truss 1 are in the top of steel box-girder flange area 5, and bottom truss 3 is located at the lower section of steel box-girder flange area 5, at top
The bottom surface of truss 1 sets multigroup pulley 4, and " C " type component is supported on the top surface that flange area chooses arm 11 using pulley 4, and using sliding
Wheel 4 can be chosen in flange area to move along the bridge on arm 11；Shaped steel scaffold board 6 is equipped with bottom truss 3 and is used as constructing operation
Platform.
In order to ensure pavement direction across bridge draining, flange area chooses arm and is typically designed to 1.5% high outside and low outside horizontal slope,
The presence of this gradient force operating platform can only inside side slip, safety that operating platform moves along the bridge ensure that with this
Property, meanwhile, during manually passage operating platform reach, if trickle skew occurs for traveling process, using instruments such as crowbars very
Easily rectified a deviation, operated again after correction.
In specific implementation, top truss 1, vertical truss 2 and bottom truss 3 are formed by the weldering of channel-section steel group；In top truss
1st, between vertical truss 2 and bottom truss 3, it is welded to connect using fixation, or be connected by screw bolts；For strengthen vertical truss 2 with
Stability between bottom truss 3, between the rod member in the both sides montant and bottom truss 3 of vertical truss 2 on correspondence position
Oblique drawbar 7 is set, forms trivet reinforcement structure；Vertical cat ladder 8 is provided with the outside of vertical truss 2, is easy to workmen
Into scaffold board 6；To improve security, railing 9 is surrounded by bottom truss 3.
In specific implementation, make top truss 1, vertical truss 2 and bottom truss 3, each truss in steel structure workshop and indulge
Formed to by two, horizontal welded by some rod member groups, each rod member uses 10# channel-section steels；Top truss 1 and the structure of bottom truss 3
Identical, the long 2500mm of direction across bridge is made, it is identical to choose the width of arm 11 with flange area；Along bridge to long 1800mm, top truss 1 is in direction across bridge
Both sides rod member on each two pulleys 4 of installation, realize along bridge to slip；Shaped steel scaffold board 6 uses 5# channel-section steel rod member vertical, horizontal groups
Entirety is welded into, and 10# I-steel is used in top surface welding steel net, the vertical rod of railing 9, cross bar uses diameter 48mm steel pipes；It is perpendicular
Operated to the design height of truss 2 with convenient construction, it is wide with vertical truss 2 to long 1800mm, the height of cat ladder 8 along bridge
600mm, formed using the weldering of 5# equal leg angles group；Oblique drawbar 7 is made using Two bors d's oeuveres 10# channel-section steels.
