The production requirement of linear binode bolt weldering web.
Summary of the invention
The technical problem to be solved in the present invention is to provide joining section manufacturing process between a kind of Steel Bridge top plate, can solve
The problem of progress needed for the fabrication process that joining section between certainly general broken line type bridge top plate uses.
In order to solve the above technical problems, the technical solution of the present invention is as follows: joining section manufactures between a kind of Steel Bridge top plate
Technique, innovative point are: specific manufacturing method is as follows:
S1: three sections of bottom plate assembly: by the bottom board unit of three sections of equal breadth on moulding bed according to horizonal base plate, the first inclined floor and
Second inclined floor successively welds；In the angle structure less than 180 °, the second inclination between horizonal base plate and the first inclined floor
It is in 180 ° of angles between bottom plate and the first inclined floor；
The installation of S2:T rib and box baseplate stiffener: equidistantly successively welding is set in middle position on three sections of same surfaces of bottom plate
Several T ribs are equipped with, and are arranged in parallel with a pair of of box baseplate stiffener with T rib outside the two sides of T rib；
The installation of S3:T row: the direction that three sections of bottom plates and T rib are respectively perpendicular on the extending direction of three sections of bottom plates is arranged in parallel
There are several T row structures, and the welding between T row and three sections of bottom plates and T rib uses the form of fillet weld；
S4: the installation of box inside web: on the inside of the two sides of T row are perpendicular to T row and three sections of bottom plate direction welding upper boxes
Web；And stiffener is welded on box inside web before welding surface；
S5: on the direction perpendicular to box inside web, several box partitions equidistantly the installation of box partition: are welded with；
And fillet weld form is used between box partition and box inside web
S6: the installation of cabinet outboard web: perpendicular to box partition direction and box inside plate parallel and perpendicular to three sections of bottoms
The welding of plate progress cabinet outboard web；Full penetration, the outer flank of cabinet are used between cabinet outboard web and three sections of bottom plates
The form of fillet weld is used between plate and box partition；
S7: it the installation of box cover and box-shaped web bracket: is welded perpendicular between box inside web and cabinet outboard web
Box cover structure is connect, and welds bracket knot in box inside web and the web installing zone formed between cabinet outboard web
Structure；
S8: several H-type brackets the welding of the outer bracket of cabinet: are welded with the wherein outside of a cabinet outboard web is corresponding with T row
Structure.
Further, the T being located on the first inclined floor arranges to form T row's box structure.
Further, it is H-type bracket box knot that the H-type bracket structure in the S8, which corresponds to T row and is formed by T row's box structure,
Structure.
The present invention has the advantages that
1) for broken line type structure, such structure needs individually raw the joining section between the Steel Bridge top plate used in the present invention
It produces, common production technology is not achieved the requirement arched upward in dogleg section and is easy to cause bending degree inadequate；It is produced using the method
Bridge top plate joining section make it be easier to reach the demand to arch upward, reduce originally using linear type single node setting bending it is pre-
The difficulty of camber, production method of the invention complies fully with design compared with the technology of existing bridge setting bending camber
It is required that the setting of the bending camber of bridge can more easily be arranged, can shorten the construction period using the manufacturing method of the present invention.
