Technical field
Equipment for bridge construction field is the utility model is related to, constructs and uses more particularly to steel structure bridge flange area Operating platform.
Background technology
Steel structure bridge with its light weight, large carrying capacity, span ability is strong, speed of application is fast the advantages that, bridge at home It is widely used in beam construction.In steel structure bridge, set mostly in steel box-girder both sides and choose arm and be used for pedestrian or non-machine Motor-car passes through.Influenceed by transporting limit for width and preventing from choosing deforming in arm transport, cargo handling process, generally, flange area chooses arm It is separately installed after steel box-girder agent structure is in place, is chosen in flange area after arm is completed to install, it is necessary to implement below flange area Choose the welding of arm and steel box-girder web, the embedding section of mending of longitudinal rib is welded, and paints the processes such as coating.In existing construction technology, for Operation below flange area, it is that aerial ladder or extraordinary high-altitude operation vehicle are coordinated as operating platform using truck crane mostly, or By the way of choosing in flange area and building temporary operating platform below arm, the former plant equipment machine-team takes high, mobile inconvenient, work Industry efficiency is low;The latter need to weld interim rod member to build operating platform on steel box-girder web, and construction cost is high and to steel case Girder construction has certain damage.
Utility model content
The utility model is to avoid the weak point present in above-mentioned prior art, there is provided it is a kind of simple in construction, make Conveniently, only need manually to elapse the steel box-girder flange area that can meet full-bridge flange area construction needs slidably constructing operation during operation 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.
Brief description of the drawings
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.
Operating platform is after spelling shaping in the utility model, and integral hoisting is in place, manually to elapse operating platform Meet full-bridge flange area construction needs.
