Technical field
The present invention relates to a kind of bridge construction construction, be specifically related to a kind of installation method for PBL shear connector in the steel case beam of steel reinforced concrete adapter section.
Background technology
Along with domestic bridge development, steel case beam and concrete box girder adapter section version are used widely. Steel reinforced concrete adapter section is that solution steel-mixed rigidity transition between the two is smooth-going, all even steel of stress transmission-mixed in conjunction with the reliable structure position connecting.
Tradition steel reinforced concrete adapter section PBL shear connector length is long, rigidity is large, should not weld, construction precision requirement is high, and steel reinforced concrete adapter section PBL shear connector construction at present does not still have ripe method.
In concrete construction, the method that conventionally adopts the PBL shear connector method construction of just first installing or PBL shear connector is cut into trifle section after adapter section steel box girder assembling completes welding after installing or sleeve to connect before adapter section steel box girder assembling is installed. The former brings a lot of inconvenience to steel reinforced concrete adapter section steel box girder assembling, welding and detection, and narrow space causes part weld seam to be difficult to welding; PBL shear connector is cut to short and small sections by the latter, and single PBL shear connector division sections is many, joint is many, be difficult to meet code requirement, and construction quality potential risk is comparatively outstanding.
Summary of the invention
The technical problem to be solved in the present invention is: propose a kind of easy construction, the assembled quick PBL shear connector installation method effective with being connected shearing resistance.
The present invention is that the technical scheme that solves the problems of the technologies described above proposition is: 1, a kind of installation method for PBL shear connector in the steel case beam of steel reinforced concrete adapter section, described steel case beam is by three sections of assembled being welded of beam body that are divided into left width beam body, stage casing beam body and right width beam body, in described left width beam body, stage casing beam body and right width beam body, comprise respectively multiple spaced biography shears, every passes and spaced apartly on shear is provided with multiple PBL shear connector installing holes, described PBL shear connector position of mounting hole respectively relatively, forms many group PBL shear connectors duct is installed; Comprise following characteristics step:
A, according to the structure of steel case beam and length, PBL shear connector is carried out to segmentation blanking and make PBL shear connector sections, and at the end mantle fiber of described PBL shear connector sections;
B, in every group of PBL shear connector installed in duct, wear two sections of PBL shear connector sections are installed, reserved position while welding between left width beam body, stage casing beam body and right width beam body is avoided in the installation site of described PBL shear connector sections, the adjacent end portion juxtaposition of described two sections of PBL shear connector sections, fixes with the interim colligation of iron wire;
C, described left width, stage casing and right width beam body are carried out to the assembled entirety that is welded into;
The iron wire of d, dismounting colligation PBL shear connector sections, adopts straight screw sleeve successively adjacent two sections of PBL shear connector sections to be connected, and the PBL shear connector piece sections that is divided into the most at last some sections connects into entirety.
Further, both sides, described steel case soffit form turning successively, described turning lays respectively at described left width beam body and Liang Ti junction, stage casing and right width beam body and Liang Ti junction, described stage casing, a described left side, in right width beam body, in PBL shear connector sections and stage casing beam body, between PBL shear connector sections, be connected by turning PBL shear connector sections, the length of turning PBL shear connector sections is less than biography shear spacing, the bending angle of described turning PBL shear connector sections and two ends mantle fiber consistent with described corner angle, at described left width, after stage casing and right width beam body are welded into entirety, turning PBL shear connector sections is just installed into biography shear, use straight screw sleeve to be connected with both sides PBL shear connector sections.
The invention has the beneficial effects as follows:
The installation method for PBL shear connector in the steel case beam of steel reinforced concrete adapter section in the present invention not only can adapt to complicated steel reinforced concrete adapter section structure, can freely adjust PBL shear connector section length and the high feature of flexibility according to design feature, also has that technique is simple, efficiency of construction is high, the field operation time is short and construction quality easily reaches the feature of the economic aspects such as related specifications requirement.
Installation method for PBL shear connector in the steel case beam of steel reinforced concrete adapter section provided by the invention, has solved the difficult problem that the steel reinforced concrete adapter section PBL shear connector installation time is long, efficiency is low, construction quality should not be controlled. Meanwhile, the installation method that the application study innovatively of carrying out for this field is used in PBL shear connector in the steel case beam of steel reinforced concrete adapter section has more wide promotional value.
