Abstract

The invention belongs to field of bridge construction, and in particular to a kind of construction method for hanging of bridge floor shoulder pole girder, comprise the following steps:Step 1: setting horizontal shoulder pole girder on cable suspension hook, control cable crane steel wire rope length tilts shoulder pole girder;Step 2: the corresponding two ends of floorings hang steel wire rope lifting floorings on shoulder pole girder, two floorings are once lifted by crane;Step 3: the first floorings of cable crane dolly handling are to installation site, highly, then the first floorings low side is positioned to bridge location screens, and shoulder pole girder continues to reduce for shoulder pole girder reduction, and the high-end positioning of the first floorings completes the first floorings and installed to bridge location;Step 4: the positioning construction of the second floorings is identical with the first floorings;Shoulder pole girder two ends hang the different steel wire rope of length respectively, and contraposition is assembled during facilitating floorings to fall beam.

Description

A kind of construction method for hanging of bridge floor shoulder pole girder
Technical field
The invention belongs to field of bridge construction, and in particular to a kind of construction method for hanging of bridge floor shoulder pole girder.
Background technology
Bridge steel box-girder, because bridge location geographical position is special, the multiple factors such as bridge structure complexity take cable crane to bridge Component is lifted.In bridge floor Slab element carries out installation process, former construction method is to use cable crane monolithic bridge counter plate list Element is installed, and there is lifting progress slowly, installation effectiveness is low.In view of this, the applicant provides a kind of bridge floor shoulder pole girder Construction method for hanging, thus this case produce.
The content of the invention
It is an object of the invention to provide a kind of construction method for hanging of bridge floor shoulder pole girder, shoulder pole girder two ends hang length respectively The different steel wire rope of degree, contraposition is assembled during facilitating floorings to fall beam.
To achieve the above object, the technical scheme that the utility model is specifically provided is:A kind of lifting of bridge floor shoulder pole girder is applied Work method, comprises the following steps:
Step 1: setting horizontal shoulder pole girder on cable suspension hook, control cable crane steel wire rope length tilts shoulder pole girder;
Step 2: the corresponding two ends of floorings hang steel wire rope lifting floorings on shoulder pole girder, two bridge floors are once lifted by crane Plate;
Step 3: the first floorings of cable crane dolly handling are to installation site, shoulder pole girder reduces height, then the first floorings Low side is positioned to bridge location screens, and shoulder pole girder continues to reduce, and the high-end positioning of the first floorings completes the first floorings peace to bridge location Dress;
Step 4: the second floorings of cable crane dolly handling are to installation site, shoulder pole girder reduces height, then the second floorings Low side is positioned to one end screens of the first floorings, and shoulder pole girder continues to reduce, and the high-end positioning of the second floorings is completed to bridge location The installation of integrated deck plate;Step 5: repeat the above steps two to four, the installation up to completing integrated deck plate.
Further, in the step one:Cable crane steel wire rope length is controlled to make the inclined angle of shoulder pole girder be 5 degree to 15 Degree.
Beneficial effects of the present invention:First, the construction method after improving, substantially increases the lifting speed of live floorings, The daily workload that can be only done five was lifted with cable crane monolithic in the past, by eight plain films can be completed after improvement daily, was pacified Dress efficiency is doubled, and shortens installation period, to completing construction task on schedule there is provided powerful guarantee.
2nd, in-site installation cost is substantially reduced, and the operating efficiency of workman and plant equipment is substantially increased after improvement, is reduced The unnecessary work holdup and plant equipment are idle, greatly save construction cost.
3rd, compared with before improvement, assembled Quality advance.The lifting of shoulder pole girder point two, is easy to assembled positioning, to the big of appearance Gap, beam section torsional deformation, can more accurately judge adjustment, improve the assembled welding quality of beam section
Brief description of the drawings
Fig. 1 is present invention construction simple diagram.
Embodiment
As shown in figure 1, disclose is a kind of construction method for hanging of bridge floor shoulder pole girder to the present invention, comprise the following steps:
Step 1: setting horizontal shoulder pole girder 1 on cable suspension hook, control cable crane steel wire rope length tilts shoulder pole girder Angle is 5 degree to 15 degree, typically takes 10 degree;
Step 2: the corresponding two ends of floorings hang steel wire rope lifting floorings on shoulder pole girder 1, two bridge floors are once lifted by crane Plate;
Step 3: the first floorings of cable crane dolly handling 2 are to installation site, shoulder pole girder reduces height, then the first bridge floor The low side of plate 2 is positioned to bridge location screens, and shoulder pole girder continues to reduce, and the high-end positioning of the first floorings 2 completes the first bridge floor to bridge location Plate 2 is installed;
Step 4: the second floorings of cable crane dolly handling 3 are to installation site, shoulder pole girder reduces height, then the second bridge floor The low side of plate 3 is positioned to one end screens of the first floorings 2, and shoulder pole girder continues to reduce, the high-end positioning of the second floorings 3 to bridge Position, completes the installation of integrated deck plate;
Step 5: repeat the above steps two to four, the installation up to completing integrated deck plate.
