Abstract

The invention belongs to the field of bridge construction and particularly relates to a hoisting construction method of a bridge deck carrying pole beam. The method comprises the following steps that firstly, the transverse carrying pole beam is arranged on a cable rope hoisting hook, and the length of a steel wire rope of a cable rope hoister is controlled to make the carrying pole beam incline; secondly, steel wire ropes are hung at the two ends, corresponding to bridge deck slabs, of the carrying pole beam to hoist the bridge deck slabs, and two bridge deck slabs are hoisted at a time; thirdly, a cable rope hoister trolley hoists the first bridge deck slabs to installation positions, the height of the carrying pole beam is decreased, the lower ends of the first bridge deck slabs are positioned to bridge site clamping positions, the carrying pole beam is continuously descended, the higher ends of the first bridge deck slabs are positioned to bridge sites, and installation of the first bridge deck slabs is completed; and fourthly, positioning and construction of second bridge deck slabs and positioning and construction of the first bridge deck slabs are the same. The steel wire ropes with different lengths are hung at the two ends of the carrying pole beam correspondingly, so that the alignment and assembly of bridge deck slabs during beam lowering are facilitated.

Description

A kind of construction method for hanging of bridge floor shoulder pole girder
Technical field
The invention belongs to field of bridge construction, be specifically related to the construction method for hanging of a kind of bridge floor shoulder pole girder.
Background technology
Bridge steel box-girder, owing to bridge location geographical position is special, the multiple factors such as bridge structure is complicated, take cable crane that bridge member is lifted. Carrying out in installation process at floorings unit, former construction method is to adopt cable crane monolithic bridge counter plate unit piece to install, and there is lifting progress slow, and installation effectiveness is low. In view of this, the applicant provides the construction method for hanging of a kind of bridge floor shoulder pole girder, and this case thus produces.
Summary of the invention
It is an object of the invention to provide the construction method for hanging of a kind of bridge floor shoulder pole girder, shoulder pole girder two ends hang the steel wire rope that length is different respectively, with facilitate floorings fall beam time para-position assembled.
For achieving the above object, the technical scheme that the present invention specifically provides is: the construction method for hanging of a kind of bridge floor shoulder pole girder, comprises the steps:
Step one, horizontal shoulder pole girder is set on cable suspension hook, controls cable crane steel wire rope length and make shoulder pole girder tilt;
Step 2, the two ends that floorings are corresponding on shoulder pole girder hang steel wire rope lifting floorings, once two floorings of lifting;
Step 3, cable crane dolly handling the first floorings are to installation site, and shoulder pole girder reduces height, then the first floorings low side location is to bridge location screens, and shoulder pole girder continues to reduce, and the high-end location of the first floorings, to bridge location, completes the first floorings and installs;
Step 4, cable crane dolly handling the second floorings are to installation site, shoulder pole girder reduces height, then the second floorings low side location is to one end screens of the first floorings, and shoulder pole girder continues to reduce, the high-end location of the second floorings, to bridge location, completes the installation of integrated deck plate.
Further, in described step one: control cable crane steel wire rope length and make the angle that shoulder pole girder tilts be 5 degree to 15 degree.
Beneficial effects of the present invention: the construction method after, improving, substantially increase the lifting speed of on-the-spot floorings, can be only done the workload of five every day with the lifting of cable crane monolithic in the past, eight plain films can be completed by every day after improving, installation effectiveness is doubled, shorten installation period, provide powerful guarantee to completing construction task on schedule.
Two, in-site installation cost is substantially reduced, and substantially increases the work efficiency of workman and plant equipment after improvement, decreases the unnecessary work holdup and plant equipment is left unused, be greatly saved construction cost.
Three, compared with before improving, assembled Quality advance. Shoulder pole girder divides two to lift, it is simple to assembled location, to the wide arc gap occurred, beam section torsional deformation, can judge more accurately to adjust, improve beam section assembly welding quality.
Accompanying drawing explanation
Fig. 1 is that the present invention constructs simple diagram.
Detailed description of the invention
As it is shown in figure 1, what the present invention disclosed is the construction method for hanging of a kind of bridge floor shoulder pole girder, comprise the steps:
Step one, horizontal shoulder pole girder 1 is set on cable suspension hook, controls cable crane steel wire rope length and make shoulder pole girder angle of inclination be 5 degree to 15 degree, generally take 10 degree;
Step 2, the two ends that floorings are corresponding on shoulder pole girder 1 hang steel wire rope lifting floorings, once two floorings of lifting;
Step 3, cable crane dolly handling the first floorings 2 to installation site, shoulder pole girder reduces height, then the first floorings 2 low side location is to bridge location screens, and shoulder pole girder continues to reduce, and the high-end location of the first floorings 2, to bridge location, completes the first floorings 2 and installs;
Step 4, cable crane dolly handling the second floorings 3 to installation site, shoulder pole girder reduces height, then the second floorings 3 low side location is to one end screens of the first floorings 2, and shoulder pole girder continues to reduce, the high-end location of the second floorings 3, to bridge location, completes the installation of integrated deck plate.
