Description
Technical field
The present invention relates to a kind of bridge field, more particularly to a kind of bridge lower edge manufacture craft.
Background technology
Orthotropic plate integrated deck structure, floorings are with lower boom, beam is connected as a single entity in length and breadth, and structure detail is complicated, system
Fixed rational welding procedure, strict control welding quality are particularly important；The control stress point of lower boom manufacture, which is removed, includes lower boom weight
Outside point control point, rational group weldering and drilling order are even more the key for ensureing this rod member geometric accuracy.
The content of the invention
The technical problem to be solved in the present invention is to provide the complete high-quality bridge lower boom manufacture craft of one kind.
In order to solve the above technical problems, the technical scheme is that：A kind of bridge lower boom manufacture craft, its innovative point
It is：Its step is as follows：
1) group weldering top plate unit, bottom board unit and riser unit：Top plate unit is a rectangle, and one is welded at its center
The ribbed stiffener extended along long axis direction；Bottom board unit is similar to top plate unit structure, procedure of processing is identical, only bottom board unit
Width is less than top plate unit width；Riser unit is two pieces of identicals and flat board in irregular shape, and system is first drawn on flat board
The position line such as line and ribbed stiffener, dividing plate and node, and center-punching, ribbed stiffener is welded by line；
2) group weldering riser unit parts：Riser is placed on platform and surveys flat, repetition measurement dividing plate, chord of arch level board, chord member water
Flat position line, it is ensured that the accuracy of positioning and the perpendicularity of riser, and ensure chord of arch level board bolt hole concentricity；Will be each
Part is welded on riser by line；Two risers are welded assembled by riser system line perpendicularity above and below guarantee；
3) assembling top plate unit and bottom board unit：Top plate unit is divided into two pieces of size, is vertically disposed on riser list
First both sides, are in integrally groove profile, and weld the main weld of chord of arch level board and riser after welding by both sides flat board spot welding in place；Bottom
Slab element is divided into two pieces of size, and two pieces of bottom board units are put respectively and are welded in the riser opposite side parallel with top plate, overall after welding
In box；
4) main weldering seam welding and part are installed：It is placed on platform, can be carried out with special frock in inversion by overall
It is fixed, convenient processing；The side sway of each part, vertical curved, distortion are first detected, a series of finishings are then carried out according to testing result, repaiied
Group weldering lateral roof unit after whole, group postwelding is in integrally box, the rear welding for carrying out box main weld；After the completion of main weldering seam welding
Continue to weld lower chord of arch ribbed stiffener, lower chord of arch dividing plate and anticollision barrier connector；180 ° of upsets will be integrally done, are noted in switching process
Meaning prevents collision, is in integrally normotopia placement location after upset, and same recruitment clamping is fixed, and carries out top plate unit penetration weld seam weld
Connect, postwelding need to detect a flaw to ensure welding quality, after the completion of the flaw detection of top plate unit melt-through weld, continuation group burn-on chord of arch ribbed stiffener,
The upper embedding benefit section of chord of arch dividing plate and each floor；
5) positioning hole and bolt hole are bored：After rod member finishing is qualified, node when being rule on platform using riser unit is base
Standard draws system line；Node side chord member and chord of arch positioning hole line are drawn on the basis of node center, with gantry numerical control drilling positioning hole, it is ensured that
Both sides riser bolt hole is concentric；Then not a node side chord member positioning hole line is drawn on the basis of node center again, gantry is used after rotation
Numerical control drilling positioning hole；Card model connects brill riser remaining bolt hole, and line card model bores two bottom plate hole, number hole drill spilled water hole, so
Group welds top plate ribbed stiffener afterwards；
6) remainder is assembled：On the basis of system line line group weldering both sides beam joint plate lateral adapter plate and other
Part, the secondary part of group weldering on the basis of system line, rule on the basis of hole crop and hand hole, and by drawing to privileged sites
Putty is sealed.
Further, the step（2）And step（3）Middle electric welding is spot welding, and solder joint is closeer.
Further, the step（4）Symmetrical welding in the same direction is required during middle welding main weld.
Further, the step（5）Must be detected after the finishing of middle rod member it is qualified can upper mounting plate line, otherwise forbidden
Marking on slab and upper lathe drill positioning hole.
The advantage of the invention is that：
1) assembling unit is progressively decomposed, rationally connection precision is high for order, and rod member is using paperback and the side of flip bonded
Method is assembled, and takes into full account the shape of part, more complicated structure and higher precision prescribed are all taken into full account and met；
2) first positioned using spot welding, determine component locations, facilitate follow-up adjustment and the welding of miscellaneous part；Comparatively dense
Solder joint proof strength, it is to avoid deformed in subsequent operation；
3) it is symmetrically welded to reduce torsional deformation in the same direction；
4) can rule drilling after rod member is qualified, improve product quality reduction in the numbers of seconds.
